Saving Helpless Animals Essay Example for Free

Saving Helpless Animals EssayDo people realize the amount of animals that ar killed each year for merely just a small portion of their body? Whether it is hide, hoofs, or urine, its never enough to make it worth killing the animal, taking parts of the body and leaving the shack go to waste. Writers such as whoreson Hammarstedt in Defending Whales and Seals, goes on to explain how he dedicated his c atomic number 18er to saving these animals. Hammarstedt states, I wanted Peter in this book because he illustrates very well how rewarding it is to follow your punk and have huge impact on t hosepipe with no voice. This quote captured my heart and led me into the research of Premarin M bes. Horses are universe hung from the ceiling by a harness, with a machine hooked to them to collect their urine. They are being sendn half(a) the amount of water a horse should have, all so their urine will be more pure.These horses are called Premarin Mares. They get the name Premarin from Pr egnant marias urine (HRT Drug astray Prescribed, 2003). Premarin is a medicine created fro women going through menopause. These women have no clue how Premarin is being made. Once the marias have gone(p) through the pregnancy and give birth, the foals are immediately on their focusing to death. They are either sent to a pre-slaughter house to gain weight, or they go straight to the slaughter house, because foal meat is a delicacy in some countries. Women direct to be aware that Premarin should not be used because horses are being abused and killed for the creation of a medicine that has negative side affects upon human consumption.Premarin is a medicine that is upraised from pregnant mares and is made by Wyeth-Ayerest to give to women who are going through menopause. The company that distributes and markets it world-wide, is Ayerst Organics Ltd. Premarin has been available to purchase since the year 1942. When stats were last checked in June of 2009, there were over nine millio n women who live in America that have purchased and been taking Premarin (HRT Drug Widely Prescribed, 2003). The medicate has been around for such a long date,people immediately assume it must work. agree to its creators, Premarin suspensors to relieve or eliminate a variety of female hormonal problems (Benefits of Premarin, 2012). Premarin is a hormone therapy that contains a blend of estrogens available in low venereal infection options.In general women terminate expect relief within a few short weeks.PREMARIN is a hormone therapy that contains a blend of estrogens available in low dose options. In general, you can expect relief to begin within a few weeks. Being a female myself, Im sure that very line is enough to spark anyones curiosity. The only thing is, these women were not informed of how Premarin is made, and the doctors make the side effects sound uniform they are no big deal. Some of the side effects Premarin will give women are chances of having a stroke is increa sed by 41%. The chances of having a heart attack are also increased by 29%. Premarin increases the chance of blood clots forming by 100%, and will increase the chances of getting meet cancer (HRT Drug Widely Prescribed, 2003). These women should just find a new medicine that is not from chemicals that have to abusively be exitn out of animals.The employment of Premarin is known to make hot flashes and night sweats become less frequent and intense. Premarin lets women begin to feel relief from hot flashes in as fiddling as 3 weeks. The Benefits of Premarin states, In a clinical trial, the lowest dose (0.3mg) of Premarin reduced the number of hot flashes from 13 to less than 3 per day at 12 weeks of therapy (Benefits of Premarin, 2012). What people dont realize is every year, there are at least 75,000 mares that are abused in order to produce Premarin. Since Premarin has been used, over one million innocent horses have died from its needs (Morrison, 2004). Since they have been res earching how Premarin is made, there have been some changes to try to serving these innocent horses. Morrison states, The amount of horses needful went from 40,000 to 20,000 overnight (Morrison, 2004).Premarin Mares will be used for up to twenty years if they turn back getting pregnant and give out good strong urine. If not then they are simply sent outside for slaughter. The harnesses that are put on the Premarin Mares make it so the horses are unable to get going around at all. Being in this harness will cause serious abrasions to the horses body. Even this will not stop them from being put in the harness over and over (Premarin, 2012). A common breed of horses that is used to produce Premarinis a draft horse. In the eleven months that mares are pregnant, six of that time their urine is painfully being taken from them. Morrison states, And the result of all these pregnancies? Lots and lots of foals, baby horses (Morrison, 2004).There are several reasons why women are so eager to use Premarin. Benefits of Premarin expresses, Premarin has been shown to significantly improve vaginal symptoms due to menopause at every dose (Benefits of Premarin, 2012). Wyeth Pharmaceuticals states, Premarins vaginal cream is the first vaginal estrogen treatment made to relieve moderate to severe vagina itching, burning or dryness (Wyeth, 2012). A small application of the cream can help to reduce or eliminate physical discomfort experienced by menopausal women during intercourse. With prolonged usage, the cream can reverse vaginal changes associated with menopause. It can take up to 3 weeks for the benefits to begin to be realized. What women dont realize is that Premarin foals get taken from their mother, and either turned into Premarin Mares, or are sent away to get fattened up and then sent to the slaughter house (HRT Drug Widely Prescribed, 2003). Once foals are born, they have almost no fancy for a good life. If the foals are not an attractive color they have no chance of being sold for normal horse uses (Premarin, 2012).Sometimes when foals are sold to good families, they have deep concern for a health problem in the foal, so they have a harder time being adopted. Foals can be bought for recreational use. Most often though, they are bought by killer buyers. The babies that are born are not allowed to stay with their mother any longitudinal than four months. Every year, there are at least twenty-five thousand babies who will be killed or who die from neglect (HRT Drug Widely Prescribed, 2003). These babies are then sent to slaughter houses or unsheltered feedlots to gain weight to be slaughtered for human consumption (Premarin, 2012). Premarin foals get eaten by humans often. According to USDA, offspring foal meat tends to be very tender. This just shows how easily these babies can be neglected, because no one cares for them. Looking on the bright side of things, Premarin has been turn up to increase bone density of the hip and the spine and ca n help prevent osteoporosis (Benefits of Premarin, 2012).This is an ongoing problem in women so the fact that Premarin can help solve this problem is a big plusfor the company. Mares used to produce Premarin are greatly abused on a unremarkable basis and being deprived of their every day needs. Horses that are well taken care of are normally put in horse barn that are around or close to 10 by 10 or even 10 by 12. These horses are being put in stalls that are eight by three-and-a-half feet. These poor horses do not have enough room to turn around. So the mares urine is stronger, the PMU farms give the mares half the amount of water they should receive on a daily basis (Premarin, 2012).The mares are kept on tiny stalls for one atomic number 6 fifty days hooked up to machines to collect their urine (HRT Drug Widely Prescribed, 2003). The mares are kept in very small areas so they cannot move or even lay down (Premarin, 2012). The horses used for Premarin are given no attention love w ise, and for a horse it is quality not bar that matters to it. A popular doctor, Dr. Ray Kellosalmi, even says, The production of Premarin is a source of pure torture to these mares (Morrison, 2004). The mares used for this are highly abused. The LCA investigation found, a still-alive mare hanging upside down with part of her leg cut off (HRT Drug Widely Prescribed, 2003).Premarin is a convenient drug to take. Premarin offers five different strengths of the drug therefore it can be given to all different women due to the convenient dosing options (Benefits of Premarin, 2012).Premarin farms, also called PMU farms, are where the neglect of these horses takes place, and where Premarin is made. There are thirty PMU farms dictated in North Dakota near the Canadian Border Premarin, 2012). There are more than five hundred PMU farms in North America with the majority being located in Canada (Premarin, 2012). Most Canadian PMU farms have re-emerged in Manitoba, Alberta, and Saskatchewan (P remarin, 2012).To collect the urine, they place a rubber funnel almost like a hose in between the horses hind legs in order to be able to get the urine. The PMU farmers who do this think it is their last hope to keep their farm going. On October 10, 2003, Wyeth Organics (Wyeth Inc.) started its first round of cuts in their PMU production contacts by notifying PMU farmers in Alberta, Saskatchewan and Manitoba that theyll be reducing the number of ranchers who produce the urine by one-third (Premarin, 2012). Premarin farms were never investigated for abuse until 1986 remember it started in 1942. The PMUfarmers try to breed their mares with stallions, hoping the foals will look more attractive, so they will sell easier at a sale. cleanup Whales and Seals is also a pointless cause. This is why Peter dedicated his life to defending them. Just like poaching these sea lives, Premarin is a cruel way to make medicine for women going through menopause. Horses are being abused daily, and wome n are not aware of how it is being produced. Women going through menopause need to be aware of how Premarin is made, in hopes that they will not purchase it, so Premarin can no longer be produced.

The Pros And Cons Of Each Approach

The Pros And Cons Of Each ApproachThe estimate fuckment team at pair Services is having a debate around how to define chores in the move break cumulation grammatical construction utilise to construct a Gantt chart. Ann, the swan manager, wants to break tasks down into the sm completelyest possible units. For example, she objected to a broad task statement c completelyed Develop a training schedule. Instead, she suggested three subtasks (1) Determine availability of training room, (2) Determine availability of attendees, and (3) take on specific dates and training convictions.K ben, a nonher attend team member, disagrees. She feels that the broader task statement is better, beca hire it allows more flexibility and will produce the same result. Karen says that if you break tasks into pieces that are in like manner small, you risk over-managing the work and spend more time on monitoring than actually performing the tasks.(a) Discuss the pros and cons of severally approac h.Breaking down tasks into little and manageable units, makes the inter relationship between those units clearer, effectively helps the planning process, easier to revise and update plans when needed, assign work packages to appropriate skill groups, which makes it easier for the project manager to macro manage the project. Tracking the build of work packages is more accurate because the timeline feature of Gantt chart carries over to WBS.Smaller tasks also carry some disadvantages like need for undue communication, unending status reporting, loss of productivity and more.For example, the below figure shows that a project that is twice as bombastic will be frequently more than twice as multifactorial. Only unity interaction among team members exists in Project A. In Project B, as umpteen as six distinguishable interactions terminate take place. Unless carefully coordinated, multiple interactions can lead to misunderstanding and delays.Large work packages (Broader tasks) c an be unclear as team members whitethorn not be sure of what they are supposed to do. There are chances that your team members could assure you about meeting the delivery date of the large lump of work and approach you for schedule extension just when you thought the work would leave been done. In totalition below are some more disadvantages of large/broader tasks.You receive less feedback to overcome this, smaller tasks are better because bulk can learn sooner if the tasks are smaller and provide better feedback. spirt index expand after the initiation of a project. Large tasks usually receive long due times. Hence in that respect might be no sense of urgency which leads to low motivation.Tasks fail if they are big After spending half of the budget, you discover that resources are not enough to finish the task on time. The only dissolving agent would be fight with neighbor projects to find more resources which is a polish off expensive because you cannot just cancel the project after spending half of the budget. So, your task would drag on forever, and consume even more resources.(b) Explain which approach you would advocate and justify why.I would like to concentrate smaller tasks. Project manager plans, monitors and tracks the work done by the team members, so tasks should be small and manageable. Trying to manage a project as one large task would be impossible. Instead, i would like to break the project down into m each smaller tasks that can be easily managed. People who drag ones heels often comment that when they wait to the last minute to complete a project, they often feel overwhelmed, and the task seems insurmountable. Breaking the task into smaller units and setting priorities, the work would be more manageable and less intimidating.Finding the correct size for the work packages is very important when planning on work breakdown, not besides big, not too small, but just correct size. If the tasks were smaller we always have option to inc rease it later if needed. However the opposite is always not possible.Work breakdown structure would help assigning tasks to individuals, monitor the work status on a regular basis and also hold people accountable for the work assigned to them. Preparing the work breakdown structure properly, you can easily maintain your schedule and people will be responsible for their digress of work (tasks assigned to them). A project task can be represented by one or several team members. In a workgroup, to complete a task, the workgroup leader should consult with the workers in order to develop the task list. A task should be broken down in to a level where an individual is able to do a task without further breaking it down into smaller units. The project task list does not necessarily describe task sequence, but the task leaders will often think in these terms. It is important for the project manager to keep in wit that these tasks must be broken down into smaller, discreet, independent wor k units, and that none are left out. Breakdown is satisfactory when individuals are identified who can regulate exactly what has to be done, how long it will take, and who will do it. If, on one unit of perspiration, several groups are each working independently of each other, the unit needs even further breakdown. Each autonomous team should have its own task. Below is a simple example of work breakdown structure. interrogation 2Point foster 10M any(prenominal) companies are under exhalation server virtualization. This is the concept of putting multiple virtual servers on to one tangible device. The payoffs can be significant fewer servers, demoralize electricity and cooling costs, lower stem and administrative costs, increased flexibility, more effective use of space, and lower maintenance costs. The costs of doing so include licensing virtualization software package, labor costs in establishing the virtual servers on to a physical device, costs of updating tables, and acce ss. However, determining throw on enthronement can be a challenge. Some companies have lost money, while others claim that they have gained a positive return on investment.(a) Suggest ways in which a company could determine its actual return on investment from server virtualization and how this would be accomplished.Server virtualization increases the rate of investment for an organization. Below are some of the ways in which server virtualization can help the organization to increase their ROI.1. bring down server maintenance, storage and interlockinging costs2. Reducing growing ability, cooling and costs pertaining to facilities3. Increased IT productivity4. Reduce business risksServer virtualization allows an organization to save money on computer hardware, floor space and resources. Virtualization uses actual servers to provide better performance without adding additional capacity, which results in savings from hardware. For example, deploy three virtual servers on one phy sical machine and it saves the need to acquire three separate machines, which may be used less frequently that too at full capacity. When the physical number of servers in an organization is decreased, this content less storage space is required. Office rents are a major expense for any business, so less space is definitely a plus. It is necessary to calculate the money to be spent on the licenses for virtualization products. Buying more RAM and software licenses are more feasible than buying innovative machines. In the long run virtualization can save money because it reduces energy consumption.Server virtualization makes an organization more effective by making use of the existing infrastructure in a better way. Migration is easier in virtualized environment.With virtualization we can just deploy an image of the existing or a new agreement or solution on the present server without a need for a new server deployment.(b) Discuss whether this is a role of project in which a ar rangings psychoanalyst would become involved and why.A organisations analyst would be involved in this type of project. Though server virtualization is a great choice there are factors to consider prior to the implementation of product. The abridgment and planning phase should be done properly to avoid any type of virtualization failure. A arrangings analyst should have better understanding of server virtualization concepts before trying to implement it in an organization. The leading virtualization solutions are easy to deploy and substance abuser friendly however might require close inspection based on the requirements of the organization. This doesnt mean that you shouldnt consider virtualization, but you should look carefully at the numbers and run a mental test bed before committing to the idea. Below are some of the notable factors that a systems analyst needs to consider before deciding on server virtualization idea. iodine point of failure When failures occur on a serve r on which all the virtualization solutions are hosted and raceway, when the virtualization solution itself fails, the system crashes.Need for powerful machines Virtual servers contain powerful hardware. It is still possible to deploy virtualization solutions with less powerful systems however the performance decreases greatly if there is no sufficient RAM and CPU power on the main system.Lower performance Issues Problems show up after the coating has been virtualized. Application performance would differ when it experiences lot of stress from different processes running on the same server. Performance issues cannot be predicted in advance.Not always possible There are applications where virtualization is not possible or not feasible. unrivaled practical example is infobase, since databases require frequent disk read and write operations, virtualization, which takes time to perform is not at all suitable for the database environment. auspices Security configurations and con cerns must also be considered when analyzing a virtualization solution.It is the job of systems analyst to carefully weigh the pros and cons while considering to go for a virtualization solution. psyche 3Point value 15The vice president of accounting says to you, the IT director, This systems development life cycle stuff takes too long. She tells you that her people know what they are doing and that all systems requests coming from her segment are necessary and important to the organization. She suggests that the IT department bypass the initial steps for any accounting department request and immediately get to work at the solution.(a) Justify your departments use of the SDLC and the consequences of omitting stages of the lifecycle in systems analysis.The Systems Development Life Cycle (SDLC) is a conceptual model that describes the stages involved in a system development project moveing from Identifying problems, opportunities and objectives through maintenance of the application . There are several models developed to guide the process involved. Documentation is crucial regardless of the type of model elect for any application and is usually done in parallel with the development process. Success of a project depends on how closely the plan was followed and implemented throughout the project development. During the initial phases, systems analyst is concerned with correctly identifying the problems, opportunities and objectives. The success of the rest of the project depends on this because if the problem is not identified correctly at the initial stages or skip this stage then the rest of the team would be addressing the wrong problem. The cost of fixing a defect in the early stages of the project is very less when compared to fixing a defect at later stages of the project development because it would cost a lot to fix the defect when project is in production stage. Below is a simple graph of cost and time graph that can explain the cost of change as we pro gress in the project.http//www.ambysoft.com/artwork/costOfChangeCurve.jpg(b) Explain to her the alternative design method actingologies used in systems analysis, how they are similar to and how they differ from the SDLC, and the appropriateness of each for different types of projects.Agile methodological analysis and object oriented methodology are the other two alternative methodologies used in systems analysis. Agile methodology is an approach based on values, principles and mettle practices. Agile methodology not only reduces the risk of misunderstanding, it also minimizes the cost of addressing any defect. Object oriented best suits situations where complex systems undergo continuous maintenance, adaption and redesign. Understanding the organization, budgeting time and resources, developing a project proposal, gathering information and sampling data from existing reports are the activities that are common in all the three methodologies (SDLC, Agile and Object Oriented methodol ogies). SDLC and object -oriented approaches require extensive planning and diagramming. The Agile and object-oriented approach allow subsystems to be build one at a time until the entire system is complete. The agile and SDLC approaches are concerned about the way data logically moves through the system. SDLC approach can be used when there are adequate resources and time to complete the full SDLC. Agile methodologies can be used when applications need to be developed speedily in response to a dynamic environment. Object-Oriented methodologies can be used when organization supports the UML learning and when systems can be added gradually, one subsystem at a time.Question 4Point value 20 pointsFlexTime is a regional chain of seaworthiness centers that provides workout facilities as well as a variety of seaworthiness classes to its members such as aerobics, martial arts, yoga, Zumba, and kickboxing. The chain has 50 facilities located in the northeastern region of the United States. Each facility employs approximately 80 individuals including managers, individualized fitness trainers, fitness instructors, receptionists, on-site physical therapists, and maintenance personnel. The owners of the chain would like to switch over their antiquated database system with an integrated system that keeps track of payroll, employee and class scheduling, inventory, and rank and file dues at each of its facilities. They have asked your systems analysis team to conduct a feasibleness analysis and to develop the system for them, assuming that it is feasible.(a) Explain how you would conduct the feasibleness analysis for FlexTime.I would start with defining the potential impact of the integrated system which can help decision makers to determine whether or not to replace their antiquated database system with an integrated system. Feasibility study report should be prepared in such a way that FlexTime can decide about cost estimation, funding and important decisions which are very essential for them to be stable and run profitably. Systems analyst should analyze the current system with the proposed integrated system and prepare detailed report that contains information related to technical, stinting and operational impact and will also include both pros and cons of both the current system and proposed system. Interviewing managers, personal fitness trainers, fitness instructors, receptionists, on-site physical therapists, and maintenance personnel, developing and managing questionnaires to interested sponsors, such as potential users of the information system, monitoring users of the current system and determine their requirements as well as their like and dislike with the current system, gathering, investigating, and analyzing documents, specifications, reports, procedures, user guides, and any other documentation relating to the operations of the current system, modeling, detecting, and simulating the tasks of the current system are some various metho ds a systems analyst can use to collect data. It pursues to determine the resources required to develop an information systems solution which includes the cost and benefits and the feasibility of the new solution(b) Provide three examples of why this project might lose technical feasibility.This project may lack Technical feasibility because Flextime doesnt have enough information technology staff to execute the project. The existing resources (hardware or software) might not be able to support the business needs. Lacks financial resources to support the proposed system. The organization might lack the expertise, time or personnel required to implement the new project.(c) Provide three examples of why this project might lack operational feasibility.This project is not adequate in terms of operational feasibility because the project might not be easy to operate. The users (managers, personal fitness trainers, fitness instructors, receptionists, on-site physical therapists, and maint enance personnel) of the project lack proper training or knowledge of the system. The project procedures might be too complex for the personnel as the system has integrations with multiple applications.(d) Provide three examples of why this project might lack economic feasibility.This project might lack economic feasibility because they might lack the finances required to wait for return on investment, so the project implementation might halt due to semipermanent payback period. They can use the profits gained with this and reinvest in other technology. In addition, benefits and costs can both be intangible, hidden and/or hard to estimate. substitute financing arrangements like renting or leasing or purchasing required hardware or software. When compared to existing system the proposed system would be integrated with many other applications, the organization may want to invest more on labor. Costs may have been underestimated (However, we did compare our costs to a comparable wor k startup costs). Furthermore, although we hoped to exhaust the potential list of project costs, there will likely be items that we must purchase.(e) Explain which of the systems development methodologies discussed in the text would you adopt to use to develop the system for FlexTime and why.I would like to use SDLC to develop the system for FlexTime. SDLC model can answer questions like Do we have the hardware or software to handle the system?, Do our computers have enough memory?, Does the new proposed system do what it is supposed to do? and many more. SDLC is used to identify the need for the system initiation, ship out the new system to the user(implementation), and de support when no longer needed(Disposition) because if we dont have a clear plan for doing all these, then it can become an expensive mistake. As each phase of SDLC requires documentation, reporting and approval, it assures that a project does not go out of hand both by changing the direction or becoming a finan cial black hole. There will not be any surprises when the system is shipped to the user because the management is aware of every step and it is documented. In short because of the planning, approval, testing and documentation activities SDLC can assure that the system can, and will work as expected.Question 5Point value 45 pointsCity College is considering introducing a new online system through which faculty and students will place textbook orders which will be implemented in fall 2011. As the systems analyst assigned to this project, you have been asked to obtain information from different user groups who will be using the new system.(a) Identify the different user groups that you would want to gather information from, and explain why.Administrators They are responsible for setup and maintaining user accounts, maintaining system, verifying whether all the hardware and software used are working properly, monitor system performance, creating backup and recovery policy to use whenev er there is a disaster, setup security policies for users, monitor network communication.Librarians It is always important to collect information from librarians because they create records for library catalogs, process library seculars for collection, assist users in locating materials, circulate library materials and handle neglectful processes, managing user records, operating customer service points, in fact librarian is the person who would have knowledge of everything in the library.Students They use library more than any other user groups identified in this case so it is very important to gather information from students to build the new online system.Faculty/Reviewers/Evaluators/Teaching Assistants As most of these people use library for traditional printed resources, inter-library loan, electronic journals, and electronic databases/article indexes. Gathering information from them would help developing online system and provide all options they need.(b) Develop an ques tion protocol that you would use to interview members of the user groups. In doing so, identify the types of questions that you might ask as well as the appropriate structure for conducting the interview.When interviewing administrators and librarians I would like to follow the protocols that include open ended questions and then move on to closed ended questions to be more focused with the interview and finally with some open ended questions and appreciate the interviewee for taking time out of his/her schedule. I might even use general probes in interviews to enable the user being interviewed to be as informative as possible in their responses. I might ask questions like Is there anything else you would like to add?. I would like to use diamond structure for conducting the interview as this structure combines the strengths of the both pyramid and funnel structure.When interviewing students and faculty I would like to start with open ended questions and then narrow the possible res ponses by using closed ended questions. I might ask questions like How do you use the library resources?. I feel funnel structure best suits to conduct the interview for this users group.(c) Make a case for or against the use of joint application design (JAD) sessions to gather information.Joint application design (JAD) sessions to gather information would not suit becauseJAD sessions require commitment of a large block of time from all participants, JAD requires minimum of two to four day commitment where participants may not do any other activities con soon.Inadequate JAD session preparations in any regard or if the follow-up report and documentation of specifications is incomplete.The necessary organizational skills may not be sufficiently developed to enable the concerted effort required to be productive in a JAD session.JAD may not be possible in our case as students may have their classes/exams going on or faculty may be busy belief in class at the time of JAD schedules.(d) D evelop a questionnaire that you would use to beset information from members of each user group.Students GroupWhich Department are you in?What courses are you taking?What types of books are required for your course?What authors books do you prefer or are preferred by your instructors?Any specific publications?Is there anything else you would like to add?Faculty GroupWhich Department are you in?What courses are you teaching?What type of books do you propose to the students?Any specific authors?Any specific publications?Is there anything else you would like to add?Librarians GroupLibrary catalogs?Any library material for collection?Any overdue processes?What books do you see students using/requesting most?Any new journals/magazines required?Any editions of books to be updated?What type of user records?Is there anything else you would like to add?Administrators GroupTypes of user accounts?What type of tools required to upgrade the search capabilities in the online library system?System performance monitoring options?What type of security policies?Is there anything else you would like to add?(e) Explain how the questionnaire might be distributed to members of each user group. Make sure to describe the benefits and drawbacks of each distribution method that you suggest, and provide a final recommendation with justification.I think we can distribute questionnaire to users in all groups via e-mail and web survey because we can orbital cavity the users quickly. Cost of taking opinions from the groups with paper is completely reduced since the surveys are taken electronically and email is free, user privacy is maintained. Responses can be automatically put in and stored electronically at users convenience. Reminders can be sent easily and are inexpensive via email and by using software we can turn email data into data tables for use in spreadsheet.(f) Determine what sampling methodology you would use to distribute the questionnaire. Justify your selection.I would use stratified sampling methodology to distribute the questionnaire. To develop an online system for text book orders the data gathered should be effective and stratified sampling methodology is often essential in such cases. Using this sampling methodology a systems analyst can gather information from different group of users/people say for example you may want to use a survey to gather data from students, faculty but you might prefer to use personal interviews to gather similar data librarians and administrators.(g) Suggest a strategy for analyzing any existing documents that are used in the textbook ordering process. Explain why you would choose this strategy and why you would select certain documents (You can be general in specifying the types of documents.)Systems analysts should consider both quantitative and qualitative documents for analyzing. Quantitative documents include analyzing reports, records and forms to determine where the organization stands currently and what the vi sion for the proposed system is. Qualitative documents include email messages, memos, web pages, procedure manuals and policies because they contain details of the expectations of behavior, the ways in which users expect to interact with information technologies. Systems analysts can take help of guidelines to systematically approach to this sort of analysis. The focus of the document analysis should be a critical investigation, rather than a mere description, of the documents. The analysis should include questions about the educational purpose of the document how librarians, faculty and students are using it, and how it is contributing to learning. Records provide periodic updates of what is occurring in the business, it can provide much useful information to the analyst. Systems analyst should make a note of performance measurement. This measurement can help analyzing the actual and intended performance of the system. Analyzing policies allows the systems analyst to gain an awaren ess of the values, attitudes and beliefs guiding the organization.

The Usage Of Wireshark Computer Science Essay

The Usage Of Wireshark Computer Science EssayThis document explains the usage of WIRESHARK, its mechanism, its detailed paygrade and demonstration. The main objective behind this report is to operate Wireshark with its powerful features, what argon the limitations / Weaknesses. This document as well as describes the main suggest of Wireshark a ample with its benefits and disadvantages in a earnings. ultimately the steps that argon required to safeguard the system by using Wireshark are also dealt.Table of ContentsOverview .... 4Mechanism of Wireshark 5 monstrance and Evaluation .. 6Limitations / Weaknesses .. 15Steps to Protect System . 15Literature Review . 16Conclusion . 17References . 181. OverviewWireshark is a considerable piece of free open source software for internet monitoring and it is a fantastic packet sniffer. It was created by Gerald Combs a computer science ammonia alum during his education period. In late 1990s it was effn as Ethereal which was used to fat her and analyse packets. However in 2006 summer due to slightly trademark and legal issues it was re numberd to WIRESHARK.Wireshark interactively examines and investigates data from http postulations, Cookies, Forms, Ethernet, Token-Ring, FDDI, live web, or a set asided file. It dejection easily decipher data and displays it as clear as possible. It does contain slightly powerful features uniform transmission control protocol Stream which allows viewing reconstructed stream of TCP session and it also has the capability to monitor UDP and SSL streams. In the same track it allows round of protocols and media theatrical roles. Wireshark uses plug-ins to eliminate peeled protocols. It is based on libpcap tool. Tethereal is a tcpdump like console which is included in it. It is capable of performing live generate of internet packets, offline network depth psychology and VoIP analysis. It is also used as protocol analysis tool.Wireshark is cross platform, easy to download and install. It comfortably strikes on UNIX (NetBSD, OpenBSD, Apple Mac OS X, and so on), LINUX (Dedian, Ubuntu, Slackware, etc.), Windows (Xp, Vista, 7, etc.). Wireshark is very similar to tcp dump and it can also work with GUI. It can be executed in tty mode by using Tshark as a command line tool. It can also access packets captured from some other sniffers such as Wild Packets, Visual net incomes Visual UpTime, Snoop, Network General Sniffer, Microsoft Network Monitor, tcp dump, CA NetMaster and many other. Users can create personalized filter strings to attain granular level of configuration. Wireshark is a top rated packet sniffer. The outstrip powerful feature of Wireshark is tracking, detecting and decoding data by using enormous array of display filters, which allows user to extract the exact traffic required. It has a standard built in three-pane packet browser. Various protocols like Kerberos, WEP, IPsec and WPA are supported for decryption. Coloring rules is one of the best features that applied for quick and intuitive analysis of packet list. The captured data packets can be saved to disk and that can be exported to various formats such as plain text, xml, or CSV.In a network Wireshark enables to access different protocol Data Units as it understands number of networking protocols. The Basic part of Wireshark software is pcap tool, but when dealt withnwindows operating systems it is known as Wincap which allows Wireshark to run on the system. Promiscuous Mode is a main feature of Wireshark which allows capturing packets across the network. It works in promiscuous mode by Network Interface tantalise (NIC). The network administrator mustiness either place the correct precautions or sniffers like Wireshark which poses several surety threats that traverse across a network. Because of those threats Virtual topical anesthetic Network uses some reliable protocols like Secure Shell (SSH), Secure Socket Layer (SSL), and Transport Layer (TLS).2. Mech anism of WiresharkWireshark is a preinstalled tool used in many Linux distributions. However in Backtrack it is a preinstalled and can be used directly from the start menu/ All Applications/ Internet / Wireshark. The main purpose of this network analyser is to capture data packets. Wireshark grabs data packets for both single request between the host and server. Now a days technology is like a Gun, much much sophisticated as it can use for both good and evil. Wireshark has number of advantages, for instance, network administrators use it for trouble shooting network problems. Security engineers use it for examining the protection problems in a network. Developers use it very often for debugging protocol implementations. Most of the folks use it to learn network protocols. Wireshark can measure data in a perfect manner but it cannot manipulate data.The following illustration describes the Wireshark function blocksWireshark function blocks. inception http//www.wireshark.org/docs/ws dg_html_chunked/ChWorksOverview.htmlGTK 1/2GTK handles all the requests (i.e) input/output for windows and it does contain source code in gtk folder.CoreThe main core glue code holds the extra blocks together in which the source code is available in root folder.EpanEpan means Ethereal Packet Analyser, it is a data packets analysing engine. It consists of Protocol Tree, Dissectors, Plugins and vast number of display filters. ancestry code for EPAN is available in epan folder. Protocol Tree holds the protocol information of the captured packets. Dissectors consist of number of protocol dissectors in epan/dissectors directory. Some protocol dissectors can be executed as plugins to eliminate new protocols where as its source code is available in plugins. Display Filters can be found in epan/dfilter directory and these are also display filter engine.WiretapThe wiretap is a library which is mainly used to read and write captured packets to libpcap and other file formats on harddisk. Sour ce code is available in wiretap directory.CaptureCapture is an engine which has captured data. It holds captured libraries which are platform independent. As a result Wireshark has number of display and capture filters.BuiltbotThe Buildbot automatically reconstructs Wireshark for the changes occurred in repositories source code and brings up some problematic changes. It provides up to date binary packages. It is helpful for bugfix and fuzz test and it also shows problems which are very hard to find. Buitbot can create binary package and source package. It can also run regression tests.3. Demonstration and EvaluationCapturing PacketsAfter enter in to Wireshark Network Analyses, click on Capture then select Interfaces as shown in Fig 1. Select the required embrasure to capture packets. each interface will be provided with Start and Options as in Fig 2. Start allows capturing data and Options button allow configuring the natural selections in the interface as shown in Fig 3.Fig 1CU sersNarenDesktop1.pngFig 2CUsersNarenDocumentsNarenStudy PlaceBack UpNarenWireshark1 (3).pngFig 3CUsersNarenDesktop3.pngCapture packets in promiscuous modeThis option lets the adaptor to capture packets not only within system but also across the network but network administrator can know about this.Limit each packet toThis option limits the maximum number of bytes to capture from each and every packet. The size includes the link layer header and other subsequent headers, so this option is generally left unset to get full frames.Capture Filters and Capture FileCapture Filters allow only specific type of protocols to enter so that it reduces amount of packets to capture. Capture File allows a file from the system to save the captured traffic. Wireshark by default uses temporary files and memory to capture traffic. duple filesThis option stores captured data to number of files instead of a single file. When Wireshark needs to capture for a long cadence this option is useful. The gener ated file name consists of an incrementing number with the creation time captured data.Stop CaptureThis option allows Wireshark to stop capturing after the given number of packets has been captured.Display OptionsUpdate list of packets in real time option saves captured files immediately to the main screen but it slows down the capture process and packet drops can be appeared. Automatic scrolling in live capture automatically allows Wireshark to scroll the packet list (i.e.) the latest captured data. This option will work when update list of packets in real time is enable. Hide capture info dialog is to hide the information while capturing. It is better to disable this option to understand packets being captured from each protocol.Name ResolutionEnable macintosh name resolution is to perform the mac layer name resolution by enabling it while capturing data. Enable network name resolution performs the network layer name resolution. It is better to disable this because Wireshark issu es DNS quires to resolve IP protocols. Enable transport name resolution this attempts Wireshark to perform transport layer transport name resolution.Data can be captured with (fig3) or without (fig2) configuration the options. Click in start button to start the capturing packets. But it is better to keep the browser ca-ca before starting the capture. Now generate some traffic and that will be captured by Wireshark.Fig 4 This was the traffic generated at that instanceCUsersNarenDocumentsNarenStudy PlaceBack UpNarenWireshark1 (4).pngFig 5 This was the traffic captured and it has many protocols like TCP, HTTP and TLSv1 etc.CUsersNarenDocumentsNarenStudy PlaceBack UpNarenWireshark1 (5).pngAs shown in below fig 6, 7 protocols can be filtered by using Filter or Expression. Filters can directly sort out after typing the required addresses. But coming to Expression user must select the required addresses from the field name. Finally click Apply button on main screen, then only it will be f iltered.Fig 6CUsersNarenDocumentsNarenStudy PlaceBack UpNarenWireshark1 (6).PNGFig 7The following Fig 8, Fig 9 shows the filtered HTTP addressesFig 8Fig 9Wireshark grabs data for each and every request between the host and server. Traffic can also be sorted by clicking on Protocol, Time, Source and Destination. But in above Fig 9 it was filtered by using Expression. In the above Fig 9 (774 http GET) address was selected and then Wireshark displayed Frame Number, Ethernet, Internet Protocol, Hypertext Transfer Protocol and few more. Among Hypertext Transfer Protocol is very important because it consists of the following data.GET /webapps/SHU-pmt-bb../bulletsHost shuspace.shu.ac.ukrnUser Agent Mozilla/..It provides some more details like Accept, Accept Language and few more as shown in Fig 9. In Fig 10 there is column at last which consists of hard cipher. Data like user id, password and cookies etc. will be embedded in that cipher. To view that data simply click on Analyze and nex t click Follow TCP Stream as shown in Fig 11.Fig 10Fig 11The above picture shows all the details in the captured data. The data in the Fig 11 doesnt contain user id and password because it was not login page. If it is the login page means here itself the user id and password will be displayed. Wireshark can also grab data from forms and examine cookies. Wireshark has so many options like start capture, stop capture restart live capture and save capture etc. Fig 12 and 13 shows how the captured data can be saved. It also shows the number of packets selected and captured by it. Wireshark can reuse that data for further investigation. It allows adding a new capture type to libpcap. When Tap interface is added to Wireshark, it can produce protocol statistics.Fig 12Fig 134. Limitations / WeaknessesSome sniffers have the best feature, metrics of network traffic can be counted without storing captured packets because some host may have tremendous amount of traffic and required to monitor for a long time without causing conflicts like inbound or outbound traffic. Bounce diagrams are very helpful to view TCP traffic but in Wireshark TCP Tap listener must be included to draw bounce diagrams. If Wireshark allows pair of Ethernet interfaces then it will be easy to test network latency. When comparing captures manually it is better to include SHA1, CRC and MD5 on protocols so that packet corruption can be eliminated.Wireshark required adding automatic update feature to Win32 for every month to update security features. Properties of the last used interface (MAC and IP etc.) must be made available so that it is easy to use variables. Wireshark must be able to capture an interface which is not in existence presently so that it can start capturing immediately after creating of that preferred interface and similarly to capture from USB and FireWire on platforms which are supported. It must also have a compressor to compress data while writing to harddisk. In recent quantify Wireshark was becoming popular in security bulletins because of several security related bugs.Protecting the systemNetwork administrators use Wireshark for troubleshooting the network problems. Protocol examination is a subprogram used to notice in a real time. The raw data sent across the network interface is helpful for network order and troubleshooting. Wireshark is used to monitoring distributed exertion and that monitored data can be used for detecting errors so performance will be improved. It is mainly used for examining the security problems and debugging protocol implementations. Easy to access and learn TCPIP protocols, MAC frame, IP datagram.Dag cards are specialised network monitoring cards. Multi-threading allows the capturing and also speedup the application by reducing the response time. The captured data can be used in any way depends on the persons goal. Sniffers are designed to solve network problems but in same they are malicious. It is very hard to identify sn iffer because of passiveness, alternatively there are some way to detect by ARP perception technique, RTT detection and some more like SNMP monitoring.6. Literature Review7. ConclusionThis report explains the operation of Wireshark Network Analyser with clear demonstration. Initially report describes the overview and neat features of Wireshark like TCP Steam, Promiscous Mode, TethereaI, Plugins, Three-Pane, PDU, NIC and cross platform working etc. In mechanism illustrated the internal function blocks, Interfaces and Packages of Wireshark. Next in demonstration part capturing procedure steps, configuration options and filters are described with graphical representation. This report mainly focuses on how Wireshark grabs data packets from the network and why it is the best among all the sniffers. Lastly some of the limitations/weaknesses that are present in Wireshark.The main objective of this assignment was to complete the Systems and Application Security module in ISS Masters and get idea of all the applications regarding to security stream. In particular, I would like to state that the assignment helped a lot to learn about all the options in Wireshark. Finally I thank Mr Neil for broad me this chance to explore my knowledge.

Environmental And European Airline Industry Analysis

Environmental And European Airline Industry digestHistoryRyanair has grown since 1985 with provided 25 staff members and a star 15-seat turbo-prop commuter plane flying between Waterford and London. By 2001 in that location be much than 1500 employees working for Ryanair and more than 10 million passengers are carried to 56 cities in 13 European countries. Nowadays the company is named as the most popular airline on the web by Google and in like manner passed out British Airways to obtain the UKs favourite airline in United Kingdom and throughout Europe.Mission and ObjectivesRyanair does not publish a formal vision or mission statement. callable to the increase of passengers, the company has re-launched as a no frills airline to meet the needs of travelling at the lowest price. It aims to expand its market share, and increase more routes and destinations. Therefore it washbowl become the 1st largest airline and maintain the send in the industry.Reasons for successThe reaso n of Ryanair success because it implements different marketing strategy to prevail the company survive in the competition and to be able to gain competitive position in the airline market. For example, its no fills strategy. In order to position itself in the marketplace, Ryanair controls own its comprises to offer the lowest fares possible and remain profitable.Chapter 2 Environmental European Airline Industry Analysis2.1 The PESTEL AnalysisThe political FactorsThe Europe Union (EU) has expanded in the past few years, and it will be a big factor runs the direction and strategy planning for Ryanair. And more or less countries give preferential treatment to companies from their own country, i.e., France government has the policy to support its own national carriers which affects the expansion of Ryanair.The Economic FactorsThe unstable fuel price is modify the business. In the face of rising fuel, hedging on future buying of fuel to stable the cost as fuel is a major cost for every airline. Also, the depreciation of US dollars affects Ryanair because customers from United States will cut their orders as US dollars are depreciating.The Socio-cultural FactorsThe increasing travelling lifestyles become a factor to affect the business of Ryanair. Nowadays people are more enjoy a travelling lifestyle, i.e., graduation trips, backpack trips etc. They love to travel all approximately the world. Therefore, these people become the major customers for the company.The Technological FactorsTechnology is rapidly improving means the whole industry is changing, becoming more environmentally friendly and efficient. more(prenominal) effective infrastructure in the airports means that some airports can charge the airlines more for landing there.The Environmental FactorsUnder the new law, the airline industry has to be more environmentally friendly. Therefore the manufacturers, designers and airline companies have to combat this together to reduce carbon dioxide emission s and less harmful to the environment so its order to postdate with EU regulations.The Legal FactorsThe whole industry is heavily regulated due to laws and they have to constantly adapt to new changes in the law, such as not allowing liquid on board. After 911, the tighten security measure has also affected the business, the government reinforce security, it increases cost, and forcing to push the airline ticket prices up.2.2 The Five Forces AnalysisCompetitive RivalryRyanair has spicyly competitive rivalry because the large number of competitors and especially since the airline industry market is completely saturated. There are already many no frills airlines, i.e., easyJet, Monarch Airlines, and Air Berlin etc. If those companies decide to compete on the same basis as Ryanair, there will be a heavy pressure on prices and margins to Ryanair.Suppliers bargaining powerThe bargaining power of suppliers is high for Ryanair. Price of aviation fuel is directly related to the cost of oi l. The costs from one supplier to the other are high because all mechanics and pilots would have to be retrained. Therefore, Boeing is the main suppliers of Ryanair. For those bigger airports where Ryanairs competitors operate, have greater bargaining power. Ryanairs policy is tried to avoid these airports and sharpen on the regional airports.Buyers Bargaining PowerThe bargaining power of buyers is medium. As customers are price sensitive to choose Ryanair, they only choose for cheapness not quality. Therefore if the prices are increased or a competitor has a lower price then they will tag on to another airline.Threat of New EntrantsThe threat of potential entrants is low because set up an airline is high capital investment and the risk is high. Also there are some barriers to entry, such as a lot of regulation and the pressure to reduce carbon emissions.Threat of SubstitutesThe threat of substitutes is high because of the competition with buses, trains, cars and ferries. These ca n all substitute the low-cost airlines like Ryanair.2.3 The Scenario AnalysisAccording to the socio-cultural factors, the market is becoming more competitive because of having the emerging and developing countries, more people indigence flights therefore more airlines in order to accommodate this and it might decrease the profits in the market share. Furthermore, Ryanair is facing the increasing trade-union pressure in Europe. nigh of the countries in Europe have formed a trade-union among each others, thus it gives the pressure for Ryanair to do business in these countries.Chapter 3 SWOT Analysis3.1 StrengthsRyanair has real a very well recognized brand name by leading low cost airline. It provides high seat density and high good performance punctual, high rate of flight completion, low baggage loss, these give a good image of the companys reliability. Ryanair has first mover advantage in fortified bargaining power in airport deals and reduces barriers to its entry into new ma rkets and airports. Over 94% of all seats are sold online so the cost of dissemination by using internet booking is lower than phone booking, also eliminates the need of travel agents. Furthermore, the single model of Boeing aircraft saves on training, maintenance and supervisory costs.3.2 WeaknessesRyanair is establish on no frills strategy, it restricted expansion possibility. The long distances of its airport from city centers can become less attractive as markets mature. Over time customers whitethorn find this a big inconvenience. Besides, the morale of employee is low. The weakening employee relations are detrimental to success in any services industry. Other weakness of Ryanair is high turnaround would increase the fuel consumption and carbon dioxide emissions, therefore the costs will be increased.3.3 OpportunitiesAs the EU enlargement, there will be a lot of new destinations opened up and complete deregulation of airline industry in all EU markets. During any financial dow nturns, the new excrete could be leased out to undercut other sources and increase entrepreneurial activities will be a source for economy air travel.3.4 ThreatsThere are several threats on Ryanair. First, impending legislations for environment protection and customer compensations increase costs. Secondly, the increase in market share at the cost of network airlines could also increase airport service charges which are currently low. Then, traditional airlines are also cutting fares and costs which could affect the market share of Ryanair. Finally, landitional fleets may require new terminals and secondary airports which mean Ryanair would need to bear higher cost.Chapter 4 Evaluations Recommendations4.1 EvaluationThere is a point-of-difference between Ryanair and larger airlines such as British Airways (BA). Ryanair is the Europes largest low-cost carrier and provide only basic-level service but BA is a high-class airline company which provides high perceived service, and they focus on difference position and backside customers so it is quite tricky for larger airlines to imitate the strategy. More than that, Ryanairs no frill strategy is sustainable for identifying their target customers who are price-sensitive and wish to spend low price to fly safely.4.2 RecommendationsA low-cost image of Ryanair that has become its brand tag will be difficult to erase when it wishes to moves up the value chain, and the upper-middle class economy travellers may seek greater value proposition, not just for low fares. I suggest Ryanair add more routes to their already extensive network and plan for expanding operations into non-European markets in the near future. Furthermore, consolidation and integration would become necessary to grow further in maturing markets which could help Ryanair to offset pressure on its costs and fares.Reference ListsCase Study on Ryanair, the biggest low-cost European Airline (Jan, 2008) onlineAvailablefrom Accessed 21/07/10Thomas M. boxf ul (2005), RYANAIR (2005) SUCCESSFUL LOW COST LEADERSHIP, onlineAvailable fromAccessed 20/07/10Yahoo Knowledge (2007), Assignment for strategic analysis, online Available fromAccessed 20/07/10

The Life and Political Achievements of Sir Wilfrid Laurier of Canada :: Biography Biographies Essays

The Life and Political Achievements of Sir Wilfrid Laurier of Canada Laurier gained great achievement over his policy-making years because herepresented Canada as a whole. His family first came to Canada dating backto the time of New France and the early Montreal years. Lauriers father, a government surveyor and a genial, settled down inCanada and got married to Marcelle Martineau. Wildfrid was their firstchild who was born on November 20, 1841. Seven years later a tragedy struckthe Laurier family when Wildfrids set about died. Since his mother died when Wildfrid was only seven, his father wantedto give him the best education possible. His father knew if he were tosucceed in Canada he would have to learn the english wrangle and ways.When Wilfrid was ten years old he got sent to an Anglo-Protestant familywho were Scottish immigrants. Here he learned the english language and theProtestant faith. Later on in his life he recalled how I fought with theScotch boys and m ade schoolboy love to the Scotch girls, with more successin the latter than in the former. Remembering the past Laurier would conservatively develop the politics of reconciliation rather than conflict. In the year 1854 the young lad went to college, De Lassomption. Inhis studies he took subjects such as Latin, Latin classics, pre-revolutionary french literature, Greek, English and some philosophy. Theeducation which Laurier got from this school was to prepare him forpriesthood but he decided to study law in Montreal at McGill University. At the University Laurier was very enceinte working and serious to try toaccomplish his first major goal which was to become a lawyer. In 1864Laurier had graduated at the top of his class and was elect to give thevaledictory address. Some of the things he said in his address were how alawyer bore heavy responsibilities. A lawyer had to maintain conversancy andjustice a lawyer had to defend the individual, especially the weak frombold to strong, and that sometimes included the state and church.Differences of language, religion or history paled in comparability tolawyers obligation to seek justice and freedom. Laurier started his law career in a small law firm in Montreal but dueto bad health he moved to a small town in Quebec called Victoriaville wherehe carried out practising law and became involved with the newspaper in

The Importance of Childhood Vaccination Essay -- Medicine Health

Since the introduction of vaccinations, medical science has managed to all but eliminate many formally fatal and debilitating childhood illnesses in countries where the immunization of children is approximately universal. Diseases such as measles, mumps, diphtheria, rubella and polio convey been relegated to a marginal status in developed countries with active immunization campaigns smallpox is in reality considered to have been completely eliminated from the earth, without a single case having been reported since roughly 1979 (Childhood). Largely centered around a study published in 1998 in the British medical journal The Lancet, there has been an upsurge in concerns of the safety of vaccinations and a resulting decrease in their usage, which has lead to a somewhat anachronistic return of these diseases. While some parents concerns over the safety of vaccinations are based upon the well-intentioned desire to keep children safe from autism, the act of not vaccinating children act ually causes far greater damage by exposing them to acquiring potentially life-threatening illnesses and removing a critical link in the chain of herd immunity.Over the dwell 12 years, a growing population of parents have chosen to avoid immunizing their children with the misguided belief that they are protecting their children from the specter of autism. One of the most general concerns in this vein centers around the MMR (Measles, Mumps, Rubella combination) vaccine. The concern over the MMR vaccine began when In 1998, Andrew Wakefield and colleagues published a paper in the journal The Lancet.

Essay --

Economies of scaleThe concept of economies of scale refers to the advantages gained when long-run average cost slump with an increase in the quantity being produced. Economies of scale are common in highly capital intense industries with very high FC such as the airline industry. In general the average total cost curve at least in the short run is U-shaped, which indicates that the average total be decline over a certain range of increasing output and then increase again until they reached their minimum. () The differentiation between short-run and long-run is non linked to a certain time period but related to the existence of fixed input agents. In the short-run there is some sweet of input that is fixed and therefore cannot easily be changed without excessive investment. In the long-run every input is variable and no fixed factors exist. () Because of economies of scale, network airlines take an inherent cost advantage over smaller ones. This is a major reason why there are very few small airlines in the industry and why there is continual consolidation.Hub airports also contribute significantly to economies of scale. Hubs are extremely costly operations, and the costs that they generate, such as multiple agitate shifts, terminal leases, and ground equipment, are fixed in the short term. Therefore, in order to spread the costs over more units of output (air seat miles (ASM)), airlines remove a strong incentive to use these assets as intensively as possible. While most airlines operate banked hubs to provide shorter connection times for their passengers, airlines such as American and Delta have experimented with rolling hubs in order to better utilize hub assets. With banked hubs, assets sometimes remain unused for extended... ... paid and unpaid seats, to determine the average count of revenue received for a paid seat we calculate revenue per revenue passenger mile (RRPM). Break-even analysis is an important measurement for a company. It is the fo rm of revenue (or unit) required in order for the companys costs to be recovered. In the airline industry, break-even called break-even load factor and is usually expressed as a percentage of total ASMs. With break-even load factor, any actual load factor greater than break-even is a positive contribution and any load factor less than break-even is a loss. Break-even load factor is an important factor when assessing routes and flights on individual basis because it is possible for an airline to report a operating profit, it whitethorn not necessarily represent a net profit since fixed overhead cost and interest income/expenses still need to be paid.
