Jack the Ripper’s identity Essay

Presentation In August 1888 an exceptional who got known as Jack the Ripper submitted the first of a progression of murders. Right up 'til the present time the character of the executioner stays a puzzle. Five ladies were severely executed in the East End of London, by a crazy person who seemed to murder all of a sudden and with no regret. For what reason was the â€Å"Ripper† ready to pull off his killings? For what reason were the police frail to stop him? These are a portion of the inquiries that despite everything puzzle Ripperologists who scan for Jack the Ripper’s character till this day, glancing in old documents and books. Evaluation OBJECTIVES Examination and increase information on: †> The improvement of the police powers in Britain in the nineteenth century. > Law and request in London in the late nineteenth century. > Whitechapel in the nineteenth century. With this information you ought to have the option to address the accompanying inquiries: †1. Portray lawfulness in London in the late nineteenth century. (15 Marks) 2. For what reason did the Whitechapel murders pull in such a great amount of consideration in 1888 (15 Marks) 3. Why were police incapable to get Jack the Ripper? (20 Marks) QUESTIONS QUESTION 1 Depict LAW AND ORDER IN LONDON IN THE NINETEENTH CENTRY. (15 Marks) Peace in London in the late nineteenth century was at a creating level, with new acts presented this century, the manner in which lawfulness was managed changed as the century was reaching a conclusion. During the early and mid nineteenth century, guards watched the avenues of London and uncommon constables-this was incapable as the quantity of regular citizens living in London dwarfed those guardians and constables to an extraordinary level. In any case, the presentation of the new Metropolitan Police Force in 1829 was set up to change the circumstance. The new police power set up by Robert Peel, was first built of 3200 men, 17 divisions, 4 monitors and 144 constables. Likewise with any significant presentation of something, there were numerous early issues for the police power. In any case, as the years past on, the Metropolitan Police power increased more understanding, and had the option to bargain all the more adequately with surrenders of peace. To pick up the people groups prominence, the Police Force painstakingly picked the uniform for its constables. The power was given a blue uniform, with a tailcoat and a head protector, which supplanted the tall cap in 1870. The ‘blue’ shade of the uniform was picked on the grounds that Londoners disdained seeing the ‘redcoats’ of the military, as this was related with savagery. Blue was the shade of the naval force, which was given ‘hero status’ in view of their commitment to the British war exertion. This, I accept was a decent initial step for the Met as it caused the individuals to acknowledge and support them. During the 1880’s, the preparation of new cops was unsuitable, a significant part of the preparation was at work and constables could frequently begin their obligation the next day. Sick preparing implied some cops were unpracticed and couldn’t manage wrongdoing. This prompted numerous episodes as the police ignored guidelines. Sick policing additionally prompted the genuine occurrence named ‘Bloody Sunday’ on the thirteenth November 1887. Most importantly, towards the century's end, the police were viewed as victimizing Londoners of the lower classes and preferring individuals in the center and high society this harmed their notoriety. Criminologist work was additionally improved as the nineteenth century advanced. From the start, there were just two controllers and six sergeants. It was expected that criminologists would identify and turn out to be excessively indulgent with crooks and because of this-become degenerate. The late nineteenth century purchased radical changes to criminologist work. In 1869, the National Criminal Record was set up and managed notorious lawbreakers, in this manner lessening the quantity of violations. The Detective Department in London was updated in the late nineteenth century-this prompted the making of a Criminal Investigations Department (CID) in 1877. In a space of 5 years, the quantity of investigators expanded by 78, as did the quantity of captures made. Expanding the quantity of analysts alone was insufficient, as this didn’t increment the productivity of their work. The criminologists needed to change the strategies which they utilized in the early and mid nineteenth century in managing offensive violations. The criminologist techniques did anyway change in 1879 in managing murder cases. Presently, the body of a casualty was not expelled from its homicide site, or whatever else to do with it. These adjustments in the investigator division indicated that lawfulness was being authorized all the more proficiently and a larger number of crooks were being put to equity than previously. Another perspective that expanded the capability of investigator work in the late nineteenth century was the presentation of crime scene investigation, finger printing and the ‘Alphonse Bertillon strategy for distinguishing proof. With these techniques, investigators had the option to look at essential or auxiliary sources got to with a killer or casualty so as to get together proof and discover who the killer is. This was a significant change since killers could be distinguished not just by a conspicuous educate lying the homicide site-this subsequently implied killers turned out to be progressively threatened and scared to complete a murdering. Generally, the improvement of the police power in London in the late nineteenth century can be depicted as improving yet inadmissible. I accept that the upgrades made to reestablish lawfulness was as yet lacking. With the number of inhabitants in London around then being 5,255,069-I think having just 1383 cops on the job was incapable. Ordinary watches couldn't stop a decided lawbreaker. The police power would need to build its size by ordinarily to give opposition and scare lawbreakers. Being in its newborn child years, I figure just time will understand this issue; in light of the fact that over the long haul, there will be upgrades in innovation, the police will acquire understanding and improve their techniques for managing wrongdoing. With the Jack the Ripper kills round the corner, a wrongdoing like this will be sufficient to show the police power what they are deficient with regards to, how they are missing and what things should be mulled over. QUESTION 2 For what reason DID THE WHITECHAPEL MURDERS ATTRACT SO MUCH ATTENTION IN 1888? (15 Marks) Over the course of about two months or thereabouts, the occupants of Whitechapel were astonished at the five killings that happened in their general vicinity by a to some degree unremorseful sexual sequential killer that was obscure and couldn't be found. The secretive killer, who came to name himself ‘Jack the Ripper’ turned into the focal point of the press and media in late 1888, and pulled in such a great amount of consideration as he submitted his somewhat realistic killings to whores who lived on an everyday premise. In every one of the five killings that the Ripper completed; he ruthlessly ravaged the whores, removing from ever organs out of their bodies utilizing his begging to be proven wrong anatomical expertise. As I would like to think, I accept the Ripper possessed anatomical/careful aptitude, as he had the option to take out specific organs like the kidneys out of his victim’s bodies without causing insignificant cuts. He additionally utilized a long bladed blade like those utilized by specialists while doing removals. The Ripper utilized this aptitude while damaging the assortments of Annie Chapman who had her small digestive organs pulled back of her midsection. Mary Kelly additionally had her interior organs evacuated on the grounds that the Ripper had a great deal of time to submit the mutilations as he was separated from everyone else in a room and could have his protection; away from open sight. I trust it was a direct result of this explanation the awful mutilations on the whores that pulled in the most regard for the individuals and police power as it demonstrated what a decided killer could do. Another part of the Jack the Ripper case that pulled in such a great amount of consideration in 1888 was Jack the Ripper himself. Individuals were anxious to know who the Ripper was, his character, his experience, and basically; why he focused on whores and cut, cut and cut off them the manner in which he did. The letters that he sent to the police made individuals and the police themselves become much progressively dubious about the Ripper. For instance, the ‘Dear Boss’ letter made individuals imagine that he was American. He depicted himself as an insane person through this letter; advising the police regarding what he will do later on, ‘I shant quit tearing them till I do get buckled.’ All these inquiries should be replied by the Metropolitan Police Force; in any case, they weren’t ready to get the Ripper. This is the motivation behind why the world press corrupted them. English paper business were anxious to sell an ever increasing number of papers nowadays as the Education Act 1870 made it necessary for everybody to go to class, implying that now the greater part of the British populace was proficient. The Fleet Street papers contended by composing articles, that more probable were wrong and temperamental. Notwithstanding, the main thing that made a difference to the papers at the time was selling, and as the British populace was excited about the homicides did by Jack the Ripper, they distributed off base material. This shows how much consideration Jack the Ripper pulled in, as to keep him in the psyches of the British populace, the very source that everybody relied upon coming clean, lied! The world press additionally assumed a major job in standing out to the homicides. They profoundly explored the killings and on occasion created bogus data and bits of gossip that made the masses considerably increasingly dreadful and scared to walk around the rear entryways of Whitechapel around evening time. Offering rewards was a strategy that the police utilized later on, which it recently thought was lacking to gather proof about Jack the Ripper and his whereabouts. By this, numerous individuals were pulled in to the case and created bogus proof exclusively to

How Does Mcewan Depict the Breakdown in Joe and Clarissa’s?

How does McEwan portray the breakdown in Joe and Clarissa’s relationship in the center area of the novel? McEwan at first depicts Clarissa and Joe as the perfect couple, catching the apparently steady relationship between two scholastics. Be that as it may, McEwan looks to investigate the breaking down of the ‘superior’ white collar class sentiment, to stress how nothing is protected. To the unconscious peruser, everything about the relationship is quiet and honorable. However challenges start to surface right off the bat in the novel.The peruser figures out how Clarissa can't shoulder youngsters; something which the peruser can see is avoided day by day life, yet clearly profoundly affects the relationship. To add to this, Joe is miserable about his status in mainstream researchers. He feels his work as a speaker isn't sufficient, and this makes his self-esteem decrease after some time. Joe aches for an ideal life, with an ideal profession and for his inclination s to be fulfilled. Everything down to the costly wine at the cookout recommends Joe looks for perfection.Similarly, Clarissa additionally looks for flawlessness yet rather, makes progress toward the perfect sentiment, glorified by her abstract symbol, John Keats. McEwan centers around a breakdown of correspondence all through the center segment of the novel. Any discussions between the couple are brief and hurried, without thought for the other’s words. Part 9 is huge for the improvement of Joe and Clarissa’s connections breakdown as the peruser is welcome to observe the occasions from Clarissa’s perspective.Through McEwan’s procedure, the peruser can see the hardships of Clarissa’s day, to perceive the day by day worries of her own and expert life. We see Clarissa’s disarray at Joe’s clear hyper express, the correspondence issues, ‘All this talking and listening that’s expected to be useful for couples’. Joe just can't disregard Clarissa; he is subject to her for mental help and he neglects to perceive when she needs time to herself.Throughout Chapter 9, we discover that Joe is trusting Clarissa and going ahead rather firmly, ‘but his power is hindering her’. Notwithstanding, it is now where we perceive that Clarissa is being recounted to the entire story, in spite of cases later in the novel that she isn’t, she just doesn’t take the right measure of intrigue. The three clear achievements of the breakdown are the inflatable occurrence, Jed Parry’s intercession and Joe’s apparent gloom. Repel shows up as the primary impetus, as he features the couple’s flaws.Trust is an enormous issue among Joe and Clarissa, as made clear when Joe neglects to tell Clarissa of Parry’s late night call, ‘I realize I committed my first genuine error when I turned on my side and I said to her â€Å"It was nothing. Wrong number. †Ã¢â‚¬â„¢ His activ ities could propose he basically didn’t need to stress Clarissa at such a period, yet in addition could ring early alerts for issues of trust. Trust issues are likewise apparent when Joe assaults Clarissa’s study, hysterically scanning for proof of an undertaking. Not long after this, they start to stay in bed separate beds, stopping the late night conversations and energetic love-production.

Performance of Sdssu in the Licensure Examination for...

CHAPTER 1 THE PROBLEM AND ITS SETTINGS Introduction High percentage of LET passers contributes greatly to the accreditation of education programs of a certain college or university. This, aside from adding zest within the vicinity of school academe, is the reason why schools offering education courses crave for high percentage of LET passers (Philippine Journal of Education, 2005). Today, prospective teachers must clear a series of hurdles to obtain and maintain a teaching certificate - one of which is to pass the Licensure Examination for Teachers (Libman, 2009). States use licensing to ensure that the only qualified teachers can be hired. This builds anxiety not only among examinees but more so far schools who turn out prospective†¦show more content†¦Four teacher education program components with key predictor variables for each are identified. First, program resources (total program expenditures) must be adequate to ensure the achievement of the learning goals and outcomes. Second, there must be sufficient faculty (student-to-faculty ratio) with the necessary qualifications (degrees earned, teaching experience) to influence program processes and outcomes. Third, the curriculum (didactic, laboratory, and professional practice hours; comprehensive examination) must support the entry-level competencies of professional practice and the achievement of learning goals and outcomes. Fourth, in order to graduate and enter professional practice, students (mean cumulative college GPA on admission) must be evaluated on the ability to demonstr ate competencies measured on the Licensure Examination for Teachers. Taking and passing the LET is the ticket to enter teaching profession which is the desire result of education students. Licensure Examination for Teachers (LET) is the professional board examination given by Professional Regulation Commission (PRC) to determine who are to be allowed to teach and who are not (http://eduphil.org/how-to-pass-the-licensure-examination-for-teachers-let.html).LET performances in terms of passing scores are often perceived as the scale in measuring the quality of education of schools offering teacher education.

Burden Of Proof In Criminal And Common Law - Free Essay Example

Sample details Pages: 5 Words: 1399 Downloads: 9 Date added: 2017/06/26 Category Law Essay Type Narrative essay Tags: Criminal Law Essay Did you like this example? He who asserts must prove. This statement of law allows us to understand that in criminal cases the onus of proof rests with the prosecution and that the standard of proof is one that must be satisfied beyond a reasonable doubt  [1]  . However, there are exceptions to this in the form of both statutory exceptions and within case law  [2]  . The statement also allows us to see that in civil cases the onus of proof rests with the party who raises the issue and the standard of proof is lessened to on the balance of probabilities  [3]  . There are two types of burdens of proof: the first is the persuasive burden which is when a party satisfies the court to the appropriate standard  [4]  . It is possible for both parties to bear the persuasive burden depending on the case in hand  [5]  . The second is the evidential burden which is when a party has to bring enough evidence in order for the court to at least consider the issue in hand  [6]  . These burdens are matter of law and will apply in each issue which is raised within the court  [7]  . In criminal cases the basic rule is that the burden of proof rests with the prosecution in order to win their case  [8]  . In the case of Slater v HMA  [9]  it was stated that: The jury was told that what is familiarly known as the presumption of innocence in criminal cases applied to the appellant (in light of his ambiguous character) with less effect than it would have applied to a man whose character was not open to suspicion. This amounted, in our opinion, to a clear misdirection in law. The presumption of innocence applies to every person with a criminal offence in precisely the same way, and it can be overcome only by evidence relevant to prove the crime with the commission of which he is charged. The evidential burden is important when it comes to criminal matters due to the presumption of innocence. It used to be the case that it was thought that the acc used was required to prove special defences however the case of Lambie v HMA  [10]  stated that this is not the case and stated that it is for the prosecution to disprove the defence beyond a reasonable doubt  [11]  . The only thing which the accused has to do is meet the minimal requirements of pointing at some evidence which allows the defence to be raised the evidential burden  [12]  . The accused must also give notice when wishing to use a special defence. There are exceptions to the general rule that it is for the prosecution to bear the burden of proof in criminal cases. There are four exceptions in which the burden of proof will shift  [13]  . The first is when the accused pleads a special defence of either insanity or diminished responsibility (which is not technically a special defence as it does not result in the accused being acquitted)  [14]  . They are named special defences as they require the accused to give written notice to the court that the se defences will be used in order for the prosecution to understand the line of evidence the defence will take  [15]  . Hume stated that when an accused wishes to plead insanity the persuasive burden will for that reason rest on the accused  [16]  . However, the evidential burden would also switch to the accused  [17]  . This is due to the fact that it would be very difficult for the prosecution to disprove this defence as the prosecution cannot force the accused to have psychiatric examinations to be done; therefore the burden is placed with the accused  [18]  . The second exception to the general rule is when other special defences are used these include alibi, self-defence or incrimination  [19]  . There is no requirement for the accused to corroborate the evidence put forward  [20]  . As well as common law exceptions to the general rule that the burden of proof lies with the prosecution in criminal case there are also statutory exceptions. These inclu de Parliament switching the burden of proof through Acts of parliament in relation to defences plead by the accused to specific crimes  [21]  . An example of this can be seen in the Criminal Law (Consolidation) (Scotland) Act 1995  [22]  which states that Any person who without lawful authority or reasonable excuse, the proof whereof shall lie on him, has with him in any public place any offensive weapon shall be guilty of an offence. However, as it is unusual for a statute to make express provision as to where the burden of proof lies the Criminal Procedure (Scotland) Act 1995  [23]  states that Where, in relation to an offence create by or under an enactment any exception, exemption, proviso, excuse or qualification, is expressed to have effect whether by the same or any other enactment, the exception, exemption, proviso, excuse or qualification need not be specified or negative in the indictment or complaint, and the prosecution is not required to prove it, but the ac cused may do so. In civil cases, the burden of proof is said to lie with he who asserts a right given to him by the law must prove the facts necessary to establish it  [24]  which allows us to understand that the burden of proof will normally rest with the pursuer  [25]  . However, the burden of proof may switch between the parties when it comes to dealing with different issues, this will usually happen when the defender is pleading certain defences (for example contributory negligence)  [26]  . The reason for this is that the parties in a civil matter are not normally required to prove a negative therefore the burden of proof will rest with the defender to prove rather than the pursuer to disprove  [27]  . There are also statutory exceptions to the general rule that in civil cases the burden of proof will rest with the pursuer  [28]  . The leading case for statutory exceptions is Nimmo v Alexander Cowan Sons Ltd  [29]  . The statute under consideratio n in this case was the Factories Act 1962  [30]  and concerned safe working practices. It was held that the burden of proof rested with the purser in order to prove that the working conditions were not safe however, the pursuer was not required to prove that it was not reasonably practicable to make them safe and if the defender wished to rely on this then the burden of proof would switch  [31]  . The standard of proof in any case depicts both the amount and the quality of evidence which has to be lead in order for the burden of proof to be released  [32]  . In criminal cases this standard is said to be one of beyond reasonable doubt  [33]  therefore, the prosecution must prove the accuseds guilt beyond a reasonable doubt  [34]  . There has been difficulty is defining what can be classed as beyond a reasonable doubt and that there can be no quantitative amount place on it  [35]  . However, it has been described as something more than a merely speculative o r academic doubt  [36]  . When the burden of proof switches to the pursuer in criminal cases the question of what standard of proof shall be used must be asked  [37]  . The case of HMA v Mitchell  [38]  states the common law position, in relation to the defences of insanity and diminished responsibility, with Lord Justice-Clerk Thomsons charge to the jury stating that: The burden of proof is on the defence, because in our law there is a presumption that a man is sane. But you must keep clearly in mind that the burden in the case of an accused person is not so heavy a burden as the burden which is laid on the CrownÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ the Crown has to prove its case beyond a reasonable doubtÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ Where, however, the burden of proof is on the accused, it is enough if he brings evidence which satisfies you of the probability of what he is called upon to establishÃÆ' ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€šÃ‚ ¦ it is a question of the balance f p robabilities. Therefore, the standard of proof changes from on beyond a reasonable doubt to on the balance of probabilities  [39]  . In relation to all other common law issues, in criminal matters, the burden of proof will remain with the Crown and should there be a reasonable doubt in the mind of the trier then the accused should be acquitted as the Crown has failed in discharging the persuasive burden  [40]  . The standard of proof which is required when a statute places the burden of proof on the pursuer is also on the balance of probabilities  [41]  . Don’t waste time!

Directory Viruses Free Essays

There are many ways to sabotage a computer. Some malicious programs create software that automatically replicates itself and spreads throughout a computer’s file system to destroy it later. One of these virus types is called the Directory Virus. We will write a custom essay sample on Directory Viruses or any similar topic only for you Order Now From its name itself, one can know that it attacks the directory and file system of a computer. The computer uses a large file that contains information about its subdirectories and files. It includes information such as the starting cluster, the name, the time and date it was created or modified, attributes such as being read-only, and other information. Every time a file needs to be accessed, it searches for the directory entry and the starting cluster, an index to the File Allocation Table or FAT. All the other cluster addresses are in the FAT. So a Directory Virus infects clusters and allocates it in the FAT. It then targets other clusters and infects other files. The destructive code is usually with executable files such as the ones ending with . EXE or . COM. The location or paths to the computer’s files will then be changed by the Directory Virus so that it can infect other files. This will be done transparently, without the user’s knowledge, until the original files will be impossible to find. Eventually, the user’s files become useless (Spam Laws, 2009). In May 1991, the DIR II virus was discovered first in Bulgaria. It is also known as Creeping Death and was written by the same programmers who coded the DIR, MG and Shake viruses. At that time, it was considered to be unique since directory viruses were still unknown. It changed directory entries only and did not change the files (Hypponen, 2010). It was eventually followed by variants such as the DIR III and DIR BYWAY viruses. The BYWAY virus appeared first in mid 1995 in Venezuala, but was possibly authored by a Chinese programmer named Wai Chan since the code is signed â€Å"By Wai Chan† (PR Newswire, 1995). It is similar to the DIR II family of viruses but alters the technique slightly by modifying directories and cross linking executable files to point to a file named CHKLISTx. MSx, containing the viral code (Paris, 2010). The BYWAY virus has an interesting story since it reveals that people from different countries often disguise themselves using other countries. The Chinese search engine, Baidu, for example was attacked by malware that showed an Iranian flag, but Baidu doubts that it was Iranian. They believe that it was American hackers who did it. In the same way, the BYWAY virus claims that it was authored by Wai Chan on August 1994. And then when the virus is triggered, it pops out a message saying, â€Å"Trabajemos Todos Por Venezuela† which means, â€Å"We are all working for Venezuela.† It also plays music simultaneously, mimicking the Venezuelan national anthem. But it is likely that the real author is neither Venezuelan nor Chinese since crooks are not likely to leave their calling cards at the scene of the crime. It is also possible to remove the virus without using disinfecting software. Simply rename all . COM and . EXE files with non-executable extensions. The virus will automatically correct the FAT. Then reboot using a clean boot disk to remove the virus in memory, and rename everything back to its executable extensions. Do this for all hard disk partitions and the virus will be removed. Unfortunately, because viruses are popularly known to wreak havoc on computers, there is an urban myth propagating in the world that every time a PC doesn’t work properly, it is always caused by a virus (Rutter, 1999). However, the fact is that not all PC problems are caused by viruses. There may be manufacturer bugs in the software or incompatibility issues with the hardware or software. Or the computer may simply be malfunctioning like any other electronic device that eventually fails. How to cite Directory Viruses, Papers

Question: Discuss about the Communication and Computing Technology. Answer: Introduction: This is based on addressing the issues which are related to the network and how it is based on the different trusted client systems. The levels are implicit with the use of the dedicated authentication server which can be used on the machines with the distinct forms of the network services like the file or the printing servers. (Jenkins et al., 2016). For this, the authentication of the requests for the services with the workstation that cannot be trusted is mainly for the identification of the users and for handling the network services. The threats related are: The threats are based on the factors with the individuals and the client working which also includes the operating systems that are from any other work stations. The issues are related to the alteration process with the network address. The workstation handles the requests that is being sent with the focus on the impersonated workstations (Moussu et al., 2017). Here, the user also works towards handling the server operations as well as the disruption problems. Solutions: The check is on the reliability of the individual clients with assuring the identity and the user who are relying on the servers with the enforcement of the security based policies. The issues are with the user authentication ID as well. The requirement of the clients to properly handle and work on the system authentication is important with the trust that is given to the client. The concern is about the requirements of the user are administered with the services that are invoked. Hence, it also needs to work on the proving of the server identity to the client as well (Khurana et al., 2016). Complete Diagram (Explanation) This includes the security and the network patterns where the secured network eaves dropped are not able to properly work on the information with the user impersonating the information. Kerberos need to work on the potential opponents with the fact that it does not have to find for any weak links. The reliability is for the services and the working that goes on Kerberos with the access based on controlling and handling the lack of availability. This also includes the availability with the check on the supported services as well. Kerberos is working on the reliability patterns with the focus on how one should employ for the distributed server architecture which is able to handle one system with the backup of the other. Considering the differences between Kerberos 4 and 5 version, there is a need to work on the updates with the patterns that require to handle the authentication with the user identity process and the user requests as well. The internet can easily be found to be secured with the involvement and the exchange of the different information which are set with the related user patterns like the username and the passwords (Zhu et al., 2017). There are different financial transactions for working on the wide variety of the scrutiny by the hackers. For the elimination, Kerberos works on the development with the wide range of the scrutiny by the hackers with the information that is exchanged with the subjected to the wide range with the hackers, and malfeasants. The website includes experience with the heavy user traffic with the forms that are for sniffing out the details from the users with the use of the hacker advantage. The functioning is based on the user requests with the payment service s that allow the authentication and working on the generation with the particular sessions keys and ID. The user puts with the details and the focus is on obtaining the services with the passwords that are exposed on in the wire. The vital data works on the encryption with the stages of the transactions (Zhu et al., 2014). IdentificationThe Kerberos V5 authentication protocol processes and the interactions with the illustration of the Network Authentication Service. The Microsoft Security Support works on the interface with the mechanism that includes the access with the components like the keys, tickets and the Key Distribution Center. Kerberos SSP works on the remote server with the workstation management using the RPC, with the printing services, client server authentication. The remote file access works on the access with the use of the Common Internet File System, distributed file system management and the referrals. The Kerberos protocol works on the reliability with the authentication techniques that involve the shared secret keys with the concepts that include the verification and works on handling the secret (Moussu et al., 2017). The problems are set with the secret key cryptography rather than sharing of the password and the communication to share the cryptographic key, with the use of the k nowledge. The party knowledge is about the encryption with the information that provides the decryption of the information. Version 4 Kerberos Version 5 Kerberos Chronology This includes the releasing of the versions 5 in the time of 1980s This was in 1993 with the better appearance. Algorithm for Key Salt There is name partially entered for the principal. The use of the principal naming with the entire planning. Encode The receiver making it right with the encoding of the system. The usage of the ASN with the coding system patterns.

Local Gov essays

Federal Versus State/Local Gov essays Throughout the Civil Rights Movement, the federal and southern state/local government battled each other on many issues. When the federal government set mandates, often times the southern state/local government had much resistance with complying. The southern state/local government opposed the Civil Rights Movement by non-compliance to federal mandates, refusal to provide adequate protection to civil rights protesters and the abuse of civil rights protesters. There were many situations when the state/local government hindered the flow of the Civil Rights Movement. Instances where the local police force did not do their job occurred. The police force was a branch of the local government and the local polices duty was to protect and serve the community. This oath to serve and protect all did not apply to African Americans. During times of protest, either African Americans received much abuse from police officers or the police officers stood around and watched African Americans be beaten. During the freedom rides, the local government fought against the protests while the federal government protected not necessarily the cause but the citizens involved. Mobs of people attacked the Freedom Riders meanwhile the local government did nothing to protect the riders. They actually encouraged the mobs to beat the Freedom Riders by turning the other cheek when it came to stopping the mobs. Not a single police officer was in sight when the rid ers arrived in Montgomery, Alabama. As a result of this lackadaisical attitude to protect the riders, Robert Kennedy had federal marshals sent into Montgomery . Despite the protection in Montgomery, the Freedom Riders had a much different experience when they entered Mississippi. Local police officers arrested and jailed many of the Freedom Riders subsequently ending their freedom ride. This was an example of how local government hindered the Civil Rights Movement. The Freedo...

Primary Crime Data Sources in the United States Essay

Primary Crime Data Sources in the United States - Essay Example This means that unreported crimes are not covered by the data. Therefore, the Uniform Crime Reports can not be said to cover all crimes but only reported crimes. They conclude that alone the Uniform Crime Reports do not provide comprehensive and conclusive data on incidence of crime in the United States so they must be considered only one part of an analysis of crime an supplemented with other sources of evidence. While they do not consider the National Archive of Criminal Justice Datas National Incident-Based Reporting System the same could be said of it. Its data is based on reported crime and leaves unreported crime unconsidered and unaccounted for. No official publications on crime rates consider unreported crime. Arguably, by definition, unreported crime cannot be considered using strictly quantitative measures. Unreported crime is best studied using other research methods such as interviews with residents of and employees of social service agencies in the city or area under examination. They may be particularly true in areas where law enforcement agencies and the criminal justice system are distrusted or feared. Lynch and Jarvis (2008) point to an even greater problem with academic statistical analysis of the Uniform Crime Reports. They note that the data is produced by and for law enforcement agencies and is intended to provide broad indicators of crime trends to law enforcement agencies. They also note that the data is not statistically rigorous, nor does it claim to be, because it was never conceived as a tool for academic analysis. Unlike the Uniform Crime Reports the National Incident-Based Reporting System also includes data on clearance or the disposition of incidents. This is particularly useful data for researchers and is not impaired by the fact that only reported incidents are included in the data set. For example, Jarvis and Regoezci (2009) used the National Incident-Based Reporting System to

Composition of fish corkscrew Essay Example | Topics and Well Written Essays - 1000 words

Composition of fish corkscrew - Essay Example Symmetry is known to play a vital role in human visual perception and aesthetics1. When all the functional parts of the fish corkscrew are in closed position, the device appears to be almost symmetrical as can be seen from figure 1. Its symmetry is, however, imperfect given the shape of the corkscrew and a section of the knife. One of the elements of the device is the saw-tooth and sharp bladed knife. The knife which is attached to the tail of the fish is made of metal and can be used to cut different objects. The cutting edge of the knife has two sections; a flat blade and a serrated blade that form one unit. The flat section of the cutting blade can be used to cut objects like a razor or ordinary knife does even as the serrated section serves to cut like a saw. The cutting and non-cutting edges of the knife meet in a curve to form a pin point that can be useful in piercing or tearing materials. The knife is attached to the tail of the fish through a hinge so that the knife can be drawn out in case it needs to be used. When not in use, the knife is pushed down and its curved non-cutting edge forms the dorsal fins the fish. At the side of the knife that overlooks the wooden body of the fish, close to the curved edge is a notch that can be used to lift the knife out of its sheath. The tail of the fish is made up of metal. Apart from being the frame upon which the knife is fixed, the tail serves to give the device its characteristic aesthetics and fish shape as can be seen in fig 2. The body of the fish which is made of wood and metal similarly gives the device its characteristic fish-like shape. The body also acts as a sheath that hides the sharp edge of the knife from view when the knife is in closed position. The body also serves to protect the bearer of the knife from harm as it keeps the knife away from immediate contact in case it is not in use. The body of the fish also serves as a hand. The body is so shapes that

Development And Implementation Of Business Strategy Marketing Essay

Development And Implementation Of Business Strategy Marketing Essay The purpose of this paper is to critically discuss the strategic methods Bavarian Motor Works (BMW Group) applied to become one of the major leading automobile brand today. With reference of BMW automobiles Case Study by Mr. Valeriano Lencioni, I will further examine what happened with the company, what are the different business strategy approaches the company could use to overpower the high competition in the automobile industry, and what is in the future for the company. Like any other business companies, BMW went through rough time when they continuously keep on losing their market share and with the presence of tight competition, everything would have been unsuccessful. With the use of business strategies, BMW was able to determine what went wrong and what they could do to survive the pressure in the industry. Organisations in a similar environment are not identical but have different capabilities. BMW has strategic advantages that sets them apart from its competitors. BMWs resources and competences developed over years for the company to survive and grow. Every company needs a foundation to continuously keep up with its changing environment and with competition. Presently, BMW is a multi-billion company that manufactures several of the best-known cars in the market. BMW has gone way far ahead from its competitors even with the pressure from competition and still manage to survive and even growing and expanding globally. What are these business strategies BMW applied all these years to get there on top? How did the company even manage to be one of the biggest car manufacturers in the present time knowing the company went bankrupt in the year 1961? What is happening in the automobile industry and what is the position of BMW in the competition? Will it still manage to survive in the future? What are the challenges in store for the company for the next 10 years? BUSINESS ENVIRONMENT AND MAIN TRENDS IN 2004 The global car market started decline in 2003, led by the drop in the market in North America and Western Europe. Other regions of the world led by East Asia are seeing further car market expansion in 2003. In 2004, projections for livelier economic growth strengthen the continuation of car market growth in Western Europe and North America. Although how laws can get stricter and how badly it can affect the companies earnings, it also develop new technologies and markets. Another major external factor affecting the current situation of BMW is that industry structure is becoming more intense. BMW is a business which could face problems in the future if it doesnt take into consideration strategic alliances. Although, the problem was that the economy in North America and Western Europe has been affected by the overcapacity in the automobile industry. It became a global economic instability as consumers from the said part of the world decided to reduce spending on non essential goods. There was lower car demand and so, sales was automatically affected. The automobile industry is becoming more and more competitive, with 6 major groups which have recently formed. Car manufacturing presently is largely affected by external social and environmental pressures, which influence both current production practices and the development of future products and technologies. Environmental standards are mostly set by government regulation and even associations within the automobile industry. These acts aim to as anti-emission laws get stricter every year, and companies look to double or triple their fuel efficiency, alternative technologies are being developed to replace the traditional gasoline engines, and have started to hit the market. Increased fuel-economy and decreasing vehicle weight are gradual changes that slowly improve automobile performance; disruptive technologies include new fuel sources such as electricity, solar energy, and fuel cells. Please refer to Appendix III: UK car production in Year 2003. Within the automobile industry, it had too many difficulties and the players in this field have experienced the troubles of surviving. The change is needed as equity prices drops and geopolitical tensions arised, including the related threat to oil prices, all having a negative impact on the economy. Increasing the safety standards for automobiles also mean that nowadays cars take longer time to be developed and manufacturers should now focus on pre-marketing activities, making cars look more desirable to consumers due to their safety. Competitive forces determine the market power of competitors, the kind of competition they engage in, the factors that give some of them a competitive advantage, and the attractiveness of that market compared to others. BMW GROUP Bayerische Motoren Werke Aktiengesellschaft (BMW) or Bavarian Motor Works is a German automobile, motorcycle and engine manufacturing company founded in 1917. The BMW Group is now one of the ten largest car manufacturers in the world and, with its BMW, MINI and Rolls-Royce brands, possesses three of the strongest premium brands in the car industry. The group also has a strong market position in the motorcycle sector and operates a successful financial services business. The company aims to generate profitable growth and above-average returns by focusing on the premium segments of the international automobile markets. With this in mind, a wide-ranging product and market offensive was initiated in 2001, which has resulted in the BMW Group expanding its product range considerably and strengthening its worldwide market position. The companys brand is extremely strong and is associated with high performance, engineering excellence and innovation. Indeed, the BMW brand is often cited as on e of the best in the world, and the company continues to launch a stream of innovative products as part of its battle with German peer Mercedes to be the worlds largest luxury car maker. II. PESTEL Analysis for BMW; its impact and how these influenced its strategy Organisations, such as BMW, need to look into the macro environment in which they exist, as these factors will have an impact and influence upon their industry. The macro environment is broken up into six main categories forming the PESTEL analysis. Automobile manufacturers must identify and select the issues which are most important to their industry in order to conduct a valid external analysis. Political/ Legal Factors Trade barriers and restrictions, import tariffs and tax policies are critical factors to consider especially for global manufacturers as they can influence the pricing levels of their products in each market and affect the profitability of a company. Also, Environmental protection laws regarding the CO2 emissions; In 2007 the European Commission proposed binding rules to cut CO2 emissions on new cars to 130 gms/km and it shows Porsche whose cars have highest CO2 output fell 2% as a result and average BMW emissions drop to 170g/km. With the threat of legislation looming BMW has shown that even premium car makers can seriously reduce CO2, stated by Jos Dings, Transport and Environment Director. Please refer to Appendix IV: CO2 Emissions by Car Brand Economic Factors The overall economic health of the car industry will have a great effect on each of the industry players. Interest rates, exchange rates and the level of unemployment can also depress demand. Most importantly the level of consumers disposable income is a critical issue particularly for manufacturers such as BMW and Jaguar, who compete in the luxury car market, as an economic downturn can seriously damage sales and revenues. Socio-cultural Factors This is an important factor to consider especially with regard to the luxury car market such as BMW. The particular lifestyles of consumers determine which strategy the organisation should pursue in order to capture the needs of its market effectively. Levels of education also affect the industry, as a highly skilled labour force is required in order to produce high performance and excellently engineered cars. Other factors are the Population demographics, Income distribution, Social mobility, Attitudes to work and leisure and Environmental concern of the market. Technological With many organisations competing with one another innovation and technological developments can help differentiate the companys product. Years ago the level of technology that was available, limited and restricted the models and designs car manufacturers could produce. Nowadays, technology has significantly moved on and companies can deliver more and more to their customers resulting in fierce competition amongst industry players to stay ahead of the market and be the best. By incorporating the latest technology advancements, car producers can lead the market in this field and achieve a competitive advantage. Environmental Although not a major driving force, manufacturers must be aware of the advantages in producing cleaner cars as there is now greater emphasis on protecting the environment. BMW have taken this into consideration and launched their Hybrid model. The result is a reduction in fuel consumption by up to 20 per cent compared with a comparable BMW running on a combustion engine alone or it could be driven by electric power only, on the combustion engine alone, or with a combination of both power units. III. BMWs competitive advantage According to Mr Lencioni, the car market was already full of good quality cars and consumers found very few ways to distinguish between many of the available brands and models. Quality was no longer an issue in the industry since most models were well built and reliable. Design and Brand Appeal became the distinguishing elements and customers choice factors. Companies that had given attention to the look of their automobiles, even this strategy can only make small gains, rather than losing market share. With this realisation, Design became the biggest factor in the fight for market share, as this feature grabbed customers attention. And with this action, automobile companies had to hire the most talented car designers which leads to massive costs for the company as well as the car prices. Pursuing quality and appeal in design was putting pressure on companies resources, so was brand building and management. It had become clear that a brand identity was one of the most effective ways to be more competitive in an industry where more and more products came to the market. BMW brand which is the circular blue and white logo represents an aircraft propeller. As company grew, the emblem evolved as the white and blue colours of the flag of Bavaria. The logo has made it easier for people to remember and has given the company more recognition. The BMW logo represents power, stylish and elegance, thus making BMW much more competitive in the market. Please refer to Appendix V: BMW logo. Apart from brand and design, BMW has able to survive through developing strong customer knowledge, special levels of service and access to distribution channels. Another method we could clearly understand the competitive advantage of BMW is through its strength of five forces. Please refer to Appendix VI: The Five Forces that Shape Industry Competition. Threat of new entrants Analyse shows that threat for new entrants is low mainly due to huge capital and cutting-edge technology. Car industry is highly depended on their suppliers, because of advancement of technology and materials needed to build car. Even though all firms produce cars, no two firms are totally different and no two firms are exactly the same. Strategic group maps display different competitive positions that rival firms occupy. Based on Information contained in perceptual map it is easy to notice that more and more firms are going into all sort of alliances which help to offer more and more cheap cars. Additionally, there are many substitutes, but these decrease if the special features of material increase. Bargaining power of suppliers and buyers Overall suppliers are weak because they are spread all over the world and cannot easily integrate forward, however more and more companies move into close partnerships with suppliers, even by acquiring them in order to reduce costs and exclusivity. The buyer concentration ratio and information availability is high as well as ratio of firms producing cars, on the other hand the power of buyers is weak due to low demand for non-consumer goods- automobile, high switching costs and low ability to backward integrate. The threats of substitutes are moderately strong because there are many different and less expensive transportation facilities. On the other hand, intense rivalry is strong because the major players are dominant in the market by nearly same technology and manufacturing processes, suppliers relationship and distribution systems. The ease of differentiating cars and price based competition. BMW is looking at entering into alliances, joint ventures, partnerships as it is the safest way of securing a market share, product attractiveness and competitive prices. In a decision to purchase a BMW product or that of the competitor, an individual will be influenced by a group of people that he or she wants to join; people in a certain social class or in a certain income level. There are also three factors that affect the buyer behaviour that a marketer must consider; they are social, personal and psychological. It will therefore be highlighted how these factors affect the consumer behaviour and in turn how the consumer behaviour affects the buying decisions. Competitive rivalry within industry BMWs attractive product variations were a very good source of strength. BMW is having a repetition of building a driving machine that respond really good and enjoyably to their drivers commands whilst also providing the safety, style, quality, reliability, and durability that help make long term ownership. On the other hand BMWs factories are measured very supple and most dynamic in Germany utilising the latest technology in each phase of its value chain. All the above strengths and many others has places BMW in a good position with respect to the main strong competitors in terms of performance, features, dealer networks , foreign markets, for example Lexus, Mercedes-Benz or Cadillac where rivalry among these competitors increases when they compete globally in US car market, Europe and Eastern Europe and South-east Asia, but BMW strong brand is more costly to be switched especially for quality conscious customers which makes strong competitors. Please refer to Appendix VII: Global ve hicle production and financial performance 2005-2006. Threat of substitute products The global marketplace is in jeopardy by lower car demand in North America and Western Europe, both comparatively established car markets that have been badly impacted by high-energy prices and very less consumer response. The global automotive market is extremely competitive. Many large businesses operate on a worldwide scale. Competitors are constantly trying to find new technologies and markets to increase global market share. Recent years have seen globalisation and consolidation strategies increase by competitors resulting in competition intensifying. BMW faces strong competition worldwide in the luxury saloon market. Traditional competition, which has always been strong from Mercedes and Audi, has intensified with the emergence of Lexus as a major player, along came Fords new model, Lincoln. IV. The future challenges for BMW BMW has modernised model almost after every few months that might shift emphasis on getting a new model to market rather than focusing on issues that may develop with existing models, issues such as software, and mechanical problems. Reflecting this possibility, BMW stock shares have dropped 41% in year 2002 as it was relying too heavily on one model, the 1 Series to uphold its high edge. BMW also earning profits due to the strong sales of the loaded models of the Mini but need to diversify, or in other words not keep all their eggs in one basket. Although this can also be identified as strength it can also be a true weakness. Strong competition with the major players that BMW needs to look out for, Lexus, Mercedes-Benz, Audi, and even Cadillac. As an example, the Lexus RX300 SUV rivals the BMW X5; the Mercedes E-Class still outsells the BMW 5 Series worldwide; Audi 3, 6 and 8 Series compete directly with BMWs 3, 5 and 7 Series; Cadillac which has a whole new generation of models, leaving buyers with strong power in building preferences. The 1 series may weaken the BMW trademark with comparison to 7 Series buyers, the 1 Series models may be viewed as cheaper cars with less quality. It could also be viewed as a tactic for BMW to obtain higher sales volumes. V. The Global Business Environment A combination of strategic models and frameworks will be used to critically evaluate the competitive landscape of the car industry in order to identify the prevailing conditions in the wider environment and the dynamics of the industry that can ultimately impact and influence HONDA and BMW car manufacturers. Car industry represents oligopolistic type of market with differentiated product features, unrestricted but hard to force entry barriers, strong competition and few dominant firms that hold most of market share. Governments rely on the car sector as well as related suppliers and services in terms of employment, taxation, GDP and balance of payments. Demand fluctuations are appearing between country markets. Increase in taxations of production which represents significant government revenue. In 1980 there were thirty car manufactures, by 2000 this had fallen to thirteen where smaller manufactures (Saab, Rolls Royce, Jaguar, and Volvo) were bought by larger companies (General Motors, BMW, Ford) Changing the upstream supply chain as component suppliers split into layers and become total solution providers. Full cell technology will replace safety as the number one technology issue. The volume of traffic in many cities around the world is forcing governments to consider a range of road pricing, congestion charging, and car and petrol taxation measures to encourage more use of public transport, potentially reducing demand for cars. High competition encourages manufacturers to locate plants in low-wage countries (Hungary, Brazil, Romania) generating job loss and resentment in traditional car manufacturing countries (Britain, America) Global demand has also emerged extensively. Please refer to Appendix VIII: Development in global demand in from the year 2004 to 2012. VI. Development and implementation of Business Strategy The automotive industry is always seeing new legislation appearing on matters such as safety and the environment. For example legislation on end of life of vehicles changed practices of many car manufacturers in 2002 and 2003 regarding materials used in car manufacture and other factors. BMW successful competitive strategies are grounded on the brand representation of BMW as a constructive and powerful; BMW reflects typically style, high value, up-to-date manufacturing and good performance to an object audience. Customer Feelings BMW is perceived as Quality Company and therefore seen as producing quality products. As a result, it is accepted among customers that BMW might charge higher prices. The BMW Group stays in fifth place amongst the worlds car manufacturers. Based on the external challenges, opportunities and potential future trends in the industry BMW should consider technological innovations looking at government policies concerning environmental issues. BMW should consider product innovation to reduce toxic emissions and to develop more efficient engines such as full cell technology which will replace standard car engines. BMW should consider all opportunities and take advantage of its strengths. Looking at the macro environment BMW should carefully examine world sales of cars, customers behaviour and shift in economy such as interest rates. For BMW to stay ahead in terms of competition and remain gaining market share, the company should understand the increasing weight in the global automotive market in developing countries and emerging markets. Collaboration between companies should be maximised in order for BMW to remain competitive and create strong links with suppliers due to soaring prices for steel, aluminium, precious metals and plastic. Cross boarder alliances and mergers should be considered by BMW in order to draw near to the Asian car manufacturers. BMW has noted that sales of its 7-Series model are up in the US, the product has been met with less enthusiasm in Europe. As Germany remains the companys most important market, this may be classed as a risk. A commonly held view is the radical restyling of the 7-Series has failed to excite the traditional BMW driver. This may be especially worrying given the releases of the new 5- and 6-Series models, as they are believed to have undergone restyling as well. If the designs prove to be too innovative or radical, the companys short-term growth could be seriously impacted. The risks associated with the introduction of a number of new models into an underperforming segment are only likely to increase the threat of failure within the segment. Competitive Strategy fitting with the Maturing Automotive industry Looking on the Automotive Industry in general we can see that it is in a maturing life cycle, where nearly all potential buyers are already users of the industry products, demand consists mainly of replacement, with growth totally depends on the competing firms abilities to attract new buyers and convince existing buyers to upgrade their usage, also the critical success factor (CSF) is mainly the cost efficiency. Throughout the firms Industry Life Cycles (ILC) many challenges faces the BMW corporate managers that needs to tailor BMW strategy , these changes on the strategy called the Strategy Fit , essentially managers will depend on certain input factors which are weighted when choosing the best strategy to fit the current ILC, these factors that affects managers decisions in choosing the company strategy depends on the industry life cycle phase introduction, growth, mature, decline, focusing on maturing and growth ILC phases as they are related to the selected companies. Maturing i ndustries challenges are mainly the slow growth in demand which generates more head to head competition, buyer become more sophisticated more familiar with competing brands with hard bargaining due to repeated purchases, for BMW more focus is on service and price combination competition, challenge of innovating new product feature of find further use of the product current features to keep attracting buyers attention. VII. BMW Strategic Effectiveness in the Market BMW took good steps in driving the costs down by focusing on the design and production, it activates Operation activity in the value chain, although the shared component is a good idea for cost reduction, but also BMW high different in the prices of its product series could be an important factor in customer perception to the concept of the product features and design, perhaps focusing more on other cost reduction areas and avoid disturbance to customer perception can be a recommended option . Based on the research it is possible to distinguish customers who follow standard patterns; buying affordable but comfortable medium size cars, are those aged between 20 and 40 years old, regardless of the sex but dependant on income and household status. These clients tend to have more urbanised and settled lifestyle. On the other hand those at middle age, male with high income and preferences tend to pay fortunes regardless comfort, fuel usage or environment issues. With regards to a variety of car models it is impossible to aim at mass market just with standard type of car. More applicable is a differentiated marketing strategy like those developed by GM, Ford and Daimler Chrysler which target clients at high and low income and offers cars with separate marketing and mixed variables. This strategy favours merger and acquisitions to overcome mobility barriers and gain presence also in luxury car segment. Strategic success for BMW in maturing industries by introducing a wide selection of features in the products, enhancing the industry value chain for example increase use of advanced technology, integrate the suppliers by internet to streamline various value chain activities, drive down unit cost, developing more economical product design, increasing sales to present customers using promotions or more services, acquiring rival firms at bargain price, expanding internationally, adapting core competency according to customer requirements and expectations and pushing it towards distinctive competency where the firm better then rivals . As part of BMW strategy tailoring by developing more economical product design, and focusing more on the technology innovation that reduces the cost in the overall value chain, for example BMW has been using new technology called RoDip-3, it is a new method for pre-treatment of the electro coating vehicle bodies that provides many enhancements and reduce cost to this process as explained by Christoph Klocke from BMW group. The first of these new pre-treatment and electro coating plants to be installed anywhere in the world is now operating in BMW group. Being one of the market leaders, BMW was very successful in adapting its Sales strategy with customer new needs and new preferences, BMW offered the BMW financial service to facilitate the customer financial payments utilising the Internet technology and many payments facilities. VIII. Conclusion In order for BMW to compete effectively within their industry, they must first identify which issues are critical in achieving successful competitive strategies. Decisions concerning the direction and development of the company must take into consideration the whole range of external issues, which have been covered throughout this report. The significant factors affecting BMW have been raised and are summarised below. These issues are critical to BMWs success. Size of organisation There are many acquisitions and mergers between industry players and so a small sized companies such as BMW must understand their vulnerability have merged with other companies to fight off industry giants. Mass market organisations also need to achieve economies of scale to remain profitable, whereas for manufacturers in the luxury niche markets this is not as vital as they charge premium prices and achieve very high profit margins. Quality of resources High quality of resources can help companies achieve a competitive advantage over others. Quality is seen as a key success factors to becoming successful within the market. Technology and Innovation Customers are demanding newer products and developments in technology and innovation can achieve this. Using the latest technology will once again strengthen the companys competitive position in the marketplace. Strong Brand image BMW has and can continue to build up a strong brand image through high quality resources. This is essential in the automobile industry as it creates a unique position in the marketplace and builds up customer loyalty making it difficult for other competitors to steal market share. Differentiation This is the key to survival. Companies can either differentiate themselves on price or through their unique characteristics of their products. Differentiating themselves from competitors gives the company a strong competitive advantage as they offer customers something exclusive, which competitors do not already provide. IX.

The Soyuz 11 Space Disaster: a Case Study in Engineering Disasters

The Soyuz 11 Space Disaster: A Case Study in Engineering Disasters ENGG 123 November 20, 2011 ABSTRACT In 1971, Soyuz 11 was the first manned spaceship to contact the first space station. As the astronauts were preparing to re-enter the earth's atmosphere the crew cab depressurized and the astronauts were killed within seconds. This paper will discuss the events that happened and how they were investigated. It will also discuss how the disaster affected future engineering decisions regarding the Soyuz missions as well as other future space adventures. i Table of ContentsAbstract†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. i Table of Contents†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. ii List of Figures†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ iii 1. 0 Introduction†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 1 2. 1 What Happened†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 3. 1 What Went Wrong†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢ € ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. 4 3. 2 What Was Learned†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦.. 7 4. 0 Summary†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 8 Works Cited†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 9 List of Figures Figure 2. 1: a) a view of Soyuz 11 docked b) a view of Soyuz 11 taking off (Space Facts, n. . )†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 2 Figure 2. 2: a) seating chart for the astronauts b) the three astronauts inside Soyuz 11 c) astronauts preparing for takeoff (Space Facts, . n. d)†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 3 Figure 3. 1: a) map of the landing route for Soyuz 11 (Svens Space Page, n. d. )†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦ 6 Figure 3. 2: a) Soyuz 11 after landing b) workers covering up the astronauts.. 7 ii Figure 3. : a) Funeral held for the three Soyuz 11 astronauts†¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦. 7 1. 0 Introduction The purpose of this paper is to provide background and information on the Soyuz 11 space disaster. This disaster occurred in 1971 and took the lives of three astronau ts who took part in the first successful visit to the world's first space station. This paper will provide insight on how the disaster actually happened, what the causes were of this disastrous event. It will provide insight on how the events that occurred were investigated and also what was learned from these events and what changed. 2. 1 What HappenedUnless otherwise stated the information in this section is provided from About. com(n. d. ) 1 Salyut 1, a space station made by the Soviets was the first space station to ever be made. It was launched on April 19, 1971. It was a large cylinder with three compartments, could be used with or without people inside of it and it could only dock one spacecraft at a time. The primary use of this space station was to study the effects of long term space travel on a human body, as well as studying effects on growing plants.On April 19, 1971 Soyuz 10 was the first spacecraft to attempt a mission out to the space station however this mission wa s unsuccessful. As the space craft attempted to dock it failed so the astronauts had to return to earth. On the return the ships air supply turned toxic but only one man passed out, all three astronauts recovered fully. On 2 June 6, 1971 Soyuz 11 embarked on a journey to the space station. This ship was originally supposed to be manned by Valery Kubasov, Alexei Leonov, and Pyotr Kolodin. Just before the launch, Valery Kubasov was suspected to have tuberculosis so this crew was replaced by three other men.They were: Georgi Dobrovolski, Vladislav Volkov, and Viktor Patsayev. Soyuz 11 successfully reached the space station and managed to hand dock the ship once they were within 100 metres. Once docked, problems began to take over the mission. Instruments and telescopes were not working, cramped space made it hard to work, and personalities were clashing. A small fire had even broke out at one point. This is when the crew decided to cut the mission six days short and go home. Right afte r Soyuz 11 undocked and made its way back to earth, all communication with the crew was lost.This happened much earlier than was to be expected. The ship made its way to earth and was discovered on June 29, 1971. When it was opened, all three members of the crew were found dead. The following images are from Space Facts(n. d. ) Figure 2. 1: a) a view of Soyuz 11 docked b) a view of Soyuz 11 taking off (Space Facts, n. d. ) a b Figure 2. 2: a) seating chart for the astronauts b) the three astronauts inside Soyuz 11 c) astronauts preparing for takeoff (Space Facts, n. d) abc 3 3. 1 What Went Wrong Unless otherwise stated the facts provided in this section come from Engineering Failures(n. . ) All the people on earth at the time thought this was a normal re-entry of a space craft. However upon opening the capsule the discovered differently. It was obvious to the people there that the crew had suffocated. Located between the orbital module and the descent module was a ventilation valve. As the two modules had been separated this valve was forced open. The two modules were connected via explosive bolts, these bolts were intended to fire sequentially or one after the other, but they actually fired simultaneously or at the same time.Because of this there was extra force put onto internal parts of the space craft. The ventilation valve had been jerked open by all this extra force. This valve was intended to automatically adjust cabin pressure but because it was actually opened in outer space the cabin pressure of the space craft very quickly reached zero, a fatal pressure for the cabin to be at. This valve was located underneath of the astronauts chairs making it impossible for them solve the problem. One of the astronauts was wearing a suit with biomedical sensors that showed he died within 40 seconds of the pressure loss.It only took 935 seconds for the cabin to reach a pressure of zero. 4 The facts in the next paragraph are from abyss. uoregon. edu(n. d. ) What cau sed all this to go wrong was a poor design. It should have been placed in a more accessible place. When thoughts were going into its design it was thought that it would only need to be used in an emergency, however no one thought what would be happening that it would need to be closed. The valve was intended for emergency but proved no use in the emergency because it was inaccessible.This problem could have been solved if the design team performed more tests, however it is impossible for a design team of a safety device to know every single situation that could happen. The following is a quote from Geoff Perry, Senior Science Master at Kettering Grammar School. 5 â€Å"I picked up my first signals for over 7 days on 28 June around 2110 UT   – Salyut on 20. 008 MHz and assumed that recovery would take place on 29 June around 2000 UT. Consequently I set the alarm clock for 3. a. m. BST hoping to see two objects indicating that Soyuz-11 had separated from Salyut   but that was not to be.We had no signals during 29 June and when 2000 UT came and went I went off watch, but, fortunately, left the time switch to do the pass at 2230 and 0300 UT. I did not believe that the Russians would worry about a recovery in darkness at this time of the year, considering their usual precision landings. However, they did worry and Soyuz-11 went two extra revs to give a daylight recovery. The time switch recorded signals 45 s after it had operated with LOS at 2247:15 +/- 15 s (allowing for possible variations in mains frequency affecting the clockwork).Peter Bentley had banked on a daylight recovery and was listening at Menai Bridge and gives LOS at 2247:27 +/- 1 s (or, as he says, +/- 5 s for 99% accuracy). I have therefore adopted 2247:25 +/- 5 s as LOS and the time of separation of the descent module and instrument module. The tragedy must have occurred minutes, or even only seconds, later. Telemetry at LOS was normal for a Soyuz recovery†.

First off the USSR never again attempted to send astronauts to the Salyut 1 space station. Eventually Salyut 1 was deorbited and burnt up. It took more than two years for another man mission to be attempted About. om(n. d. ) The Soyuz spacecraft went through a lot of modifications. The first main difference was that it was redesigned to only carry two astronauts instead of three. This allowed more room inside which allowed for the astronauts to wea r space suits during the launch and the landing. The Soyuz capsule remained this way until a new design in 1980 which allowed three astronauts. 4. 0 Summary The Soyuz 11 space disaster was an extremely unfortunate event. Three astronauts died from a malfunction that should have been fixable. This is a

Prone Positioning On Critically Ill Health And Social Care Essay

In my nursing experience, I have worked in both the neonatal intensive attention unit ( NICU ) and the paediatric intensive attention unit ( PICU ) . When I worked in the NICU, our babies were positioned prone ( face down ) for comfort grounds for the bulk of a 24 hr period. Our neonatologists seldom used sedation or trouble direction resources for our automatically ventilated patients. In the PICU I presently work in, all of our automatically ventilated patients are given uninterrupted medicines for both sedation and hurting, nevertheless prone placement is about ne'er used. When I have positioned patients prone in the past, most nurses look cross-eyed at me as though I have done something incorrect. Past research has suggested that prone placement is a curative manoeuvre that improves oxygenation in both paediatric and big patient populations ( Curley et al. , 2006 ) . However, some clinical tests in both paediatric and big populations have demonstrated that there is no betterment in clinical results for the patient ( Curley et al. , 2006 ) . In other surveies, when a patient is placed in the prone place, it has been shown that there is an increased in terminal expiratory lung volume and improved ventilator-perfusion fiting taking to better oxygenation ( Gattinoni et al. , 2001 ) . As you can see, there is assorted informations from many surveies proposing prone positioning leads to break clinical results for patients. Besides, as I was researching, I truly could n't happen a survey or literature that was new within the last 5 old ages. There is a current demand for updated research surveies and information. Hopefully I can carry through and add to the research with my proposed survey.Purpose, Aims, and HypothesissThe intent of this research survey would be to bring forth informations to assist infirmaries develop a policy, process and protocol for prone placement in critically sick, paediatric patients. The informations collected from this survey can add to the literature and hopefully convey current evidence-based pattern to PICUs across the state. Harmonizing to Polit & A ; Beck ( 2008 ) , purposes can be defined as the particular accomplishments a research worker would trust to accomplish by carry oning a research survey. My proposed survey has two specific research purposes.Aim 1To prove the effectivity of prone placement in automatically ventilated, critically sick paediatric patients, related to betterments in oxygenation.Aim 2To analyze techniques in airway direction of a automatically ventilated, critically sick paediatric patient, to find the safest nursing pattern in prone placement.HypothesissFor Aim 1, the hypothesis is that paediatric patients, who are critically sick and automatically ventilated, will hold better positive clinical results related to betterment in oxygenation in prone placement than in supine placement. The void hypothesis is that there is no difference in prone or supine placement in patient clinical results. For Aim 2, the hypothesis is that there will be safe techniques in airway direction in prone placement for the automatically ventilated, critically sick paediatric patient. The void hypothesis is that there is no safe technique in airway direction in the prone place based on continued, critical inauspicious events.BackgroundThe reappraisal of literature on the effects of prone placement in automatically ventilated patients has mixed ideas. Surveies conducted by Dr. Martha Curley and her research squad from Boston Children ‘s Hospital have refuted and so accepted the usage of prone placement in automatically ventilated, critically sick paediatric patients. Curley et Al. ( 2000 ) researched the physiologic alterations of automatically ventilated paediatric patients and evaluated the safety of prone placement who experienced acute lung hurt. The information was collected from a single-center prospective instance series from October 1997 to March 1999. The sample was 25 paediatric patients with bilateral paranchymal disease necessitating mechanical airing with a partial force per unit area of arterial oxygenation ( PaO2 ) to the fraction of divine O ( FiO2 ) ratio of less than or equal to 300 millimetres of quicksilver ( mm Hg ) ( Curley et al. , 2000 ) . The patient ‘s ages ranged from 2 months to 17 old ages. The participants were placed prone for 20 hours a twenty-four hours â€Å" until clinical betterment or decease occurred † ( Curely et al. , 2000, p. 156 ) . After run intoing eligible standards, informations collected consisted of arterial blood gases, critical marks ( temperature, bosom rate and arterial blood force per unit area, and cardinal venous force per unit area. Ventilator scenes and the figure of staff utilized and the clip it took to turn a patient were besides collected. The research workers besides collected informations on the medicine profile, particularly comfort medicines such as morphia and diazepam, and assessed force per unit area ulcers and presenting. â€Å" Features of the survey population are expressed as frequences, mean ( +/- SEM ) , or average with interquartile scopes ( IRQs ; 25th and 75th percentile ) † ( Curley et al. , 2000, p. 158 ) . The survey revealed that when prone place informations measurings were compared to the patient ‘s supine measurings, there were immediate and cumulative betterments in oxygenation ( Curley et al. , 2000, p. 161 ) . The research workers conclude that their survey suggests informations that prone placement is both safe and effectual in paediatric patients with ALI. Dr. Curley and her co-workers believe that this survey provides a foundation for a hereafter randomized survey to look into early and repeated prone placement for this paediatric population. Dr. Curley and her co-workers took on a prospective, multi-center randomized survey from August 2001 to April 2004. The hypothesis of this survey was that kids with ague lung hurt treated with prone positioning would hold more ventilator-free yearss than those treated with supine placement. Patients were included if they were age 2 hebdomads to 18 old ages old, intubated and automatically ventilated with a ratio of a PaO2 to FiO2 of 300 or less, bilateral pneumonic infiltrates, and no clinical grounds of left atrial high blood pressure ( Curley et al. , 2005 ) . Exclusion standards included patients less than 2 hebdomads of age, less than 42 hebdomads post conceptual age, had relentless hypotension or intellectual high blood pressure, cardiac related respiratory failure, and a figure of other medical conditions listed by the writers in their article. Of 8017 patients screened, merely a sum of 102 participants were included in the survey. A information and safety supervising board stopped the test at the interim analysis based on the futility fillet regulation. Ninety-four patients had completes the 28-day survey period. Of these 94, 47 were in each of the groups. After statistical analysis had been done, it was determined that if the survey had reached the planned registration of 180 patients, the chance of showing a difference in ventilator-free yearss between intervention groups was less than one per centum ( Curley et al. , 2005, p. 232 ) . The survey found that there was no statistically important difference of ventilator-free yearss between supine and prone placement in paediatric patients with acute lung hurt. Dr. Curley and her co-workers do non back up the continued usage of prone placement of paediatric patients as a curative intercession to better results in acute lung hurt ( Curley et al. , 2005, p. 236 ) . This province counters the research decisions drawn from Curley et Al. ( 2000 ) . Interestingly, Dr. Curley continued her research by executing a secondary analysis on this information collected in 2006. The intent of this secondary analysis was to depict the effects of prone positioning on airway direction, mechanical airing, enteric nutrition, hurting and sedation direction and staff use in paediatric patients with acute lung hurt ( Curley et al. , 2006 ) . The research workers suggest that their informations really shows that prone placement can be accomplished safely in critically sick paediatric patients. The research workers besides province that they believe patients can be safely assess and managed piece maintained in the prone place for drawn-out periods of clip, every bit long as 20 back-to-back hours ( Curley et al. , 2006, p. 417 ) . In this article on secondary analysis performed by Dr. Curley and her co-workers ( 2006 ) , they province that prone placement should go on to be used in critically sick kids as a enlisting manoeuvre in acute lung hurt to better oxygenation, lessening force per unit area wounds, and decreased bronchopulmonary compaction. These research workers besides province that this is the first survey to clearly show that prone placement can be accomplished safely. After researching prone placement in critically sick, automatically ventilated paediatric patients, I wholeheartedly agree. I believe that this is why these surveies could be replicated to assist formalize the protocols developed by Dr. Curley and her co-workers.SignificanceThe significance of a research survey on prone placement in paediatric patients is overpowering. In my ain personal experience, there has ne'er been grounds presented to my nursing co-workers or myself on whether prone placement is really safe and effectual. As ant ecedently stated, in reexamining the literature, there are really few clinical surveies that would be considered good mentions as true province of the art, evidence-based nursing pattern. In fact, I can non believe that merely Dr. Martha Curley has taken this undertaking on for the paediatric population. This proposed survey will be able to place the effectivity of prone positioning on improved oxygenation in a automatically ventilated paediatric patient. From survey informations aggregation, techniques in safe air passage direction could assist ease the usage of prone placement in paediatric patients of all ages and sizes and possibly advance more positive clinical results. In my survey, I hope to retroflex Dr. Curley ‘s methods utilizing her protocols, with some minor tweaking. This proposed survey should add to the organic structure of literature. The significance of this survey could assist formalize Dr. Curley ‘s protocols from her past surveies and besides assist make a criterion of pattern for prone placement.Research MethodsSample, Setting and RecruitmentThe mark population to be studied would be critically sick, paediatric patients runing from ages 2 hebdomads to 18 old ages of age. Inclusion standards will besides include patients with acute respiratory hurt necessitating cannulation and mechanical airing. Exclusion standards will be patients with respiratory hurt or failure of cardiac nature. Patients will besides be excluded if they have spinal instability or hold had abdominal surgery, as it would non be safe for these patients to be prone positioned. Patients with tracheotomies will be excluded. I would trust to include patients on conventional airing and high frequence hovering airing. Patients will be excluded if they weigh over 200 lbs, as the protocol will merely utilize three staff members to turn the patient, and this may be insecure in a patient of this size. The survey participants will be recruited from paediatric intensive attention units from infirmary centres willing to take part. In day-to-day unit of ammunitions, we would allow the paediatric critical attention doctors determine if the patient ‘s medical position was stable plenty to be eligible for survey standard. Randomization of patients will be done between prone placement and supine placement by utilizing a consecutive figure system. Centers will be provided envelopes with cards denominating between prone and supine placement and assign as each new participant is eligible. A sample size that would mirror Dr. Curley ‘s would be ideal. I hope to obtain at least 100 participants, but purpose for 200 participants. With 200 participants, the hope is to duplicate the original sample size, duplicate the figure of prone-to-supine and supine-to-prone bends, and increase the cogency of the research.Data Collection and InstrumentationFor my research survey, I hope to develop a systematic extension reproduction of the old surveies done by Dr. Curley and her research squad ( Curley et al. , 2000 ; Curley et al. , 2005 ; Curley et al. , 2006 ) . Dr. Curley and her co-workers ( 2006 ) developed a prone placement protocol for bedside nurses to follow in respects to analyze participants. The protocol is attached in Appendix1, nevertheless a brief drumhead is provided to assist assistance in the shaping of informations aggregation and instrumentality. When a patient has been met standards and is designated as eligible for the survey, informations will be collected based on the Pediatric Risk for Mortality III ( PRISM III ) ( Pollack et al. , 1997 ) . Demographics such as age, race, and ethnicity will be categorized. An anteroposterior thorax radiogram, in the supine place, should be obtained to document and guarantee that the endotracheal tubing ( ETT ) is positioned decently in the deep windpipe. The security of the ETT shall be assessed every bit good, based on the establishments current protocols. The size of the ETT, whether it is cuffed or uncuffed, and arrangement shall be paperss as Ten centimetres ( centimeter ) at the gum, as in â€Å" the patient has a 4.5 cuffed ETT, taped firmly at 12 centimeter at the gum † . The turnup of an ETT should be inflated with the minimum leak technique: inflate turnup until an air leak is ascultated at end-inspiration while maintain turnup force per unit area & gt ; 25 millimeter Hg ( Curley et al. , 2006, p. 420 ) . Security of the ETT and arrangement at the gum will be documented after each bend from the supine-to-prone and prone-to-supine placement every bit good as every 4 hours while in the prone place. The nurse or respiratory healer will doc ument whether or non the patient had a nonelective extubation during the bend. In respects to soothe and clamber unity, the patient ‘s should hold separately sized caput, thorax, pelvic, and leg shock absorbers to place the patients while prone ( Curley et al. , 2006, p. 419 ) . The end is to hold the patient positioned prone, with their shoulders, hips and lower limbs supported while their venters has room to stick out ( towards the bed ) and custodies can be tucked under the venters. The existent shock absorber will be difficult to set up, as every infirmary uses different positioning devices, nevertheless, I will offer the thoughts of slackly rolled covers or the Eggcrate stuff cut to the appropriate size. It will be documented if the patient has developed a force per unit area ulcer, and the ulcer will be staged harmonizing to National Pressure Ulcer Advisory Panel ‘s ( NPUAP ) description. The NPUAP ( 2007 ) established four phases of force per unit area ulcers. The first phase includes force per unit area sores that include non-blanchable inflammation, with integral tegument, normally over a cadaverous prominence. Phase two includes shoal, unfastened ulcers with a ruddy or pink pigmentation, without sheding of the tegument. Stage three ulcers include a full thickness tissue loss. Hypodermic fat is normally seeable at this phase and shedding may be present. In a phase four ulcer, the ulcer is stage three with seeable bone, musculus or sinew. A patient will stay positioned prone for 20 hours of the twenty-four hours and supine for 4 hours a twenty-four hours. The length of clip a patient is prone and supine will be recorded. Ongoing measurement will be done on all organic structure systems, including pneumonic and circulatory. Arterial blood gases will be obtained 1 hr prior to a patient being positioned prone and 1 hr after the patient has been prone. To maximise safety, staff will use bedside nurses and respiratory healers during chances for turning. The respiratory healer should be responsible for the unity of the tubing and turning the patients head, bedside nurse 1 shall be responsible for the turning of the shoulders, thorax and weaponries, and beside nurse 3 shall be responsible for the turning of the hips and legs. The prone positioning protocol that is attached as Appendix 1 which will be at the bedside of every patient for the nurses and respiratory healers to follow consequently.Datas AnalysisHarmonizing to Polit & A ; Beck ( 2008 ) , there are two wide categories of statistical trials, parametric and nonparametric. Parametric trials normally involve the appraisal of parametric quantities, require measurings on an interval graduated table, and presume that the variables for distributed usually for a population. These trials are frequently considered the most power and are normally preferred by research workers ( Polit & A ; Beck, 2008, p. 591 ) . Nonparametric trials do non gauge parametric quantities, normally used when the sample size is little or the information is considered non-normal. Figure 22.5 in Polit & A ; Beck ( 2008, p. 592 ) is a speedy mention for choosing bivariate statistical trials. Harmonizing to Polit & A ; Beck ( 2008 ) , the Fisher ‘s exact trial will be used to prove the significance of the differences in the two interventions ( Polit & A ; Beck, 2008, p. 601 ) . Fisher ‘s exact trial or x2 trial will be used to compare prone and supine groups in their baseline features and results that will be calculated on an single patient footing. Based on the categorical informations, such as the oxygenation of the patient, related to the arterial blood gases, I think a Fisher ‘s exact trial will be the best trial. The accidental extubation rate during bends will be calculated utilizing an exact binomial trial for comparing the rates of two Poisson procedures. For prone patients, Wald ‘s statistic, distributed as a qi square, will be calculated based on results evaluated after alterations in placement. The figure of staff utilized and the length of clip involved in the place turns will be analyzed utilizing signed rank trials such as a Wilcoxon rank trial. Once all information has been collected, synthesized and analyzed, the research will be drafted into a manuscript and submitted to the Pediatric Critical Care diary. Before the survey begins, it will be reviewed, and hopefully approved, by the IRB. Before a patient becomes a participant of the survey, written informed consent will be obtained from a parent or legal defender. Both female and male patients will be utilized, and the exclusion standard is entirely based on patient safety. The participants will be allocated to the prone and supine placement groups reasonably by utilizing random assignment. Complete decrease of prejudice can non be established because it will be impossible for the clinicians to non cognize whether or non their patient is positioned prone or supine. With the assorted placement protocols and adjustments with pressure-reducing stuffs, I hope to diminish the incidence of compromised tegument unity and uncomfortableness. This survey does non object, and encourages the usage of sedation and hurting medicines while the participants are automatically ventilated.
