Police scandals are an untallied cost of the drug war Essay Example for Free

Police scandals are an untallied cost of the drug war Essay The FBI, the Drug Enforcement Administration, and even the Coast Guard have had to admit to corruption. The gravity of the police crimes is as disturbing as the volume. In New Orleans, a uniformed cop in league with a drug dealer has been convicted of murdering her partner and shop owners during a robbery committed while she was on patrol. In Washington, D. C. , and in Atlanta, cops in drug stings were arrested for stealing and taking bribes. New York State troopers falsified drug evidence that sent people to prison. And it is not just the rank and file. The former police chief of Detroit went to prison for stealing police drug-buy money. In a small New England town, the chief stole drugs from the evidence locker for his own use. And the DEA agent who arrested Panamas General Noriega is in jail for stealing laundered drug money. The drug war is as lethal as it is corrupting. And the police and drug criminals are not the only casualties. An innocent 75-year-old African-American minister died of a heart attack struggling with Boston cops who were mistakenly arresting him because an informant had given them the wrong address. A rancher in Ventura County, California, was killed by a police SWAT team serving a search warrant in the mistaken belief that he was growing marijuana. In Los Angeles, a three-year-old girl died of gunshot wounds after her mother took a wrong turn into a street controlled by a drug-dealing gang. They fired on the car because it had invaded their marketplace. The violence comes from the competition for illegal profits among dealers, not from crazed drug users. Professor Milton Friedman has estimated that as many as 10,000 additional homicides a year are plausibly attributed to the drug war. Worse still, the drug war has become a race war in which non-whites are arrested and imprisoned at 4 to 5 times the rate whites are, even though most drug crimes are committed by whites. The Sentencing Research Project reports that one-third of black men are in jail or under penal supervision, largely because of drug arrests. The drug war has established thriving criminal enterprises which recruit teenagers into criminal careers. It was such issues that engaged law-enforcement leaders most of them police chiefs from fifty agencies during a two-day conference at the Hoover Institution in May 1995. Among the speakers was our colleague in this symposium, Mayor Kurt Schmoke, who told the group that he had visited a high school and asked the students if the high dropout rate was due to kids being hooked on drugs. He was told that the kids were dropping out because they were hooked on drug money, not drugs. He also told us that when he went to community meetings he would ask the audience three questions. 1) Have we won the drug war? People laughed. 2) Are we winning the drug war? People shook their heads. 3) If we keep doing what we are doing will we have won the drug war in ten years? The answer was a resounding No. At the end of the conference, the police participants completed an evaluation form. Ninety per cent voted no confidence in the war on drugs. They were unanimous in favoring more treatment and education over more arrests and prisons. They were unanimous in recommending a presidential blue-ribbon commission to evaluate the drug war and to explore alternative methods of drug control. In sum, the tough-minded law-enforcement officials took positions directly contrary to those of Congress and the President. One hopes that politicians will realize that no one can accuse them of being soft on drugs if they vote for changes suggested by many thoughtful people in law enforcement. If the politicians tone down their rhetoric it will permit police leaders to expose the costs of our present drug-control policies. Public opinion will then allow policy changes to decriminalize marijuana and stop the arrest of hundreds of thousands of people every year. The enormous savings can be used for what the public really wants the prevention of violent crime.

Barriers and Methods for Inter-Professional Healthcare

Barriers and Methods for Inter-Professional Healthcare Understanding inter-professional healthcare In the field of healthcare, inter-professional healthcare is important while facing every patient. In this report, it will list out what is inter-professional healthcare, methods to implement and consider the benefits and the barriers to the implement. Definition of inter-professional healthcare Inter-professional healthcare seems to be a hard term; in fact, it is used to refer to â€Å"two or more professions working together as a team with a common purpose, commitment and mutual respect† (Freeth et al. 2005, cited in Dunston et al., 2009, p. 6). In a simple explanation, inter- professional healthcare is a group of medical professions work as a team and request teamwork to achieve their goal, as known as cure the patients. The definition of teamwork is Interdependent performance become possible which according to actual behaviors, cognitions and attitudes. (Sallie et al., 2013) Methods used to implement inter-professional In teamwork, three essential, overlapping jobs are need, which is coordination, communication and shared responsibility (Hayes, 2014). Here are some methods can be do during inter-professional healthcare. Team discussion Problem solving through a team discussion is one of the methods. During discussion, defining problem and goals decision is needed which making a clear direction for the team for follow and achieve it. Also, opinions seeking about the problem form appropriate profession may help the team to discuss and expand the problem. Each member contribute their own unique professional perspective may make the problem become easier to solve. After giving opinions and advices, it is possible to plan out some possible solutions or patient handling plans. Giving opinions about each solution then evaluate them and choose the best one to process. At the end, summarize the plan and agree on distribution of tasks across team members (Hayes, 2014). Conflict management Another method can be apply on inter-professional healthcare is conflict management. No matter in any discussion, conflict may be occur and disturb the progress of problem solving. The meaning of professional diversity is â€Å"the conflict is inevitable, but also necessary† (Hayes, 2014, p.9). According to helpguide.org, the ability to successfully resolve conflict as follow: manage stress as soon as possible while people still remain alert and calm, self-emotion and behavior management, the feelings which people being expressed has to be careful, also be aware of and respectful of differences. (Conflict resolution skills, n.d., para.9) Benefits of inter-professional healthcare For benefits, it can be divided into four groups: patients, health care professional, educators or students, and health care delivery system. Patients With healthcare professional applied inter-professional healthcare, the outcomes of patient are improved. Also, the patient will have an effective care and reduce in costs and mistakes form the professional (Menken, 2011). Health care professional In health care professional, continuous interaction, coordinated efforts and knowledge sharing among the professionals is needed during work (american speech-language-hearing association, n.d., para.1). With inter-professional healthcare applied, the professional may improve the skills which mention above. Furthermore, according form world health organization, it point out that each professional may learn about, with and from different professional members (world health organization, 2010) Health care delivery system According to American speech-language-hearing association, it point out that the health care system are facing an impact on several problem, such as the health care practitioners requirement increase, the number of health care practitioners having retirement in increase, greater demands being placed on existing health care professional by increasing complexity of patient care, ETC.(American speech-language-hearing association, n.d., para.2).With inter-professional healthcare, the human resources can be used to move toward optimal health-services and better health outcomes (world health organization, 2010). Barriers to inter-professional healthcare implementation Difficulty may appear while doing inter-professional healthcare. Here are some examples which may cause it hard to proceed. Miscommunication Quoting the words form a physician leader at Brigham and Women’s Hospital, â€Å"the communication line just wasn’t there. We thought it was, but it wasn’t. We talk to nurses every day but we aren’t really communicating.† (gittell, 2009, p.5). Communication is the main part in inter-professional healthcare. it is needed in every case, which helps the healthcare professional to understand the problem, doing discussion and plan a solution. When communication is misleading, problem solving will be disturb and hard to process. Miscommunication may occur in these situations: things happen in high frequency of changing and working with different professional. Things in rapid changing Things happen which rapidly changing may lead to miscommunication. Quoting the words from a nurse administrator at Massachusetts General Hospital â€Å"miscommunication between the physician and the nurse is common because so many things are happening so quickly.† (gittell, 2009, p.5). Giving an example, the patient in and out of the hospital is so quick. Working with different professional Every patient is a unique case, the need of the patients are different. As a result, the healthcare professional needs to work with different professional with different background. Giving an example, caring a diabetes patient in general needs a dietitan, oral health, podiatrist, GP, physiotherapist, MRS, OT and optometrisits. With different professional background, each of the professional has different level of understanding in the problem. The hardest part is let the team member understand other professional view. Quote back the physician leader from about, they seem to be communicating with nurses every day, but they cannot understand their words (gittell, 2009, p.5). For suggestion, different professional have to explain to the team member their wording because some of them may not appear in other field. Conflict management Good management of conflict may improve the effectiveness of the team, in opposite, bad conflict management may become a barrier to implement inter-professional healthcare. According to helpguide.org, one or both parties feel a dangerous in a situation is a conflict (Conflict resolution skills, n.d., para.6). in a simple way to express, two members of the team arguing the treating method for a patient and both members don’t give off their opinion. If the conflicts cannot be solved, it continues to fester (Conflict resolution skills, n.d., para.6) and have a possibility of harming the health of the patient. Clam the member down, discuss the problem again and finding the most suitable solution is the idea of solving a conflicts. Conclusion In conclusion, due to the problem we are facing in healthcare industry, such as healthcare professional loss, funding in medical field, ETC., inter-professional healthcare may become more important and be the best way to use most of the human resource, But there are some difficulty to proceed. In most of it, explain and conflict control are the solution. References: Dunston, R., Lee, A., Lee, A., Matthews, L., Nisbet, G., Pockett, R., Thistlethwaite, J., White, J.

Airline Reservation System Ars Software Requirements Specifications Computer Science Essay

Airline Reservation System Ars Software Requirements Specifications Computer Science Essay Airline reservations system (ARS) is a online software application used to reserve and retrieve information and perform transactions related to air travel. Originally designed and performed by airlines, ARSes were later developed for the use of travel agencies. Major ARS operations that book and sell tickets for multiple airlines are known as Global distribution systems (GDS). Airlines have divested most of their direct holdings to dedicated GDS companies, who make their systems accessible to consumers through Internet gateways. Modern GDSes are providing the services like booking hotel rooms and rental cars as well as airline tickets. They also provide access to railway reservations in some markets although these are not always integrated with the main system. REQUIREMENTS DOCUMENT First we are developing a Software Requirements Specification (SRS) document that specifies what an airline reservation system should and should not do. The SRS document is divided into five sections namely System Objectives Mainly we discuss the goals and objectives of the system categorized based on the viewpoint of the airline company and the customer. They help in a top-down development of the SRS. System Context This section clearly depicts the environment and boundaries of the ARS and the entities with which it interacts. It helps us see how the system fits into the existing scheme of things. What the system will do by itself and what it expects other entities to do is clearly delineated. Functional Requirements These requirements states the functions of the system what it should do and what it should not. This will includes the most common requirements of the customer in addition to some additional features. like reserving tickets, rescheduling tickets etc. Freedom from ambiguity and navigability were kept in mind while documentation. A consistent terminology has been followed throughout and the terms are explained in the appendix. The subsections follow a logical sequence that reflects the real world. For example, a customer cannot reschedule a ticket unless he has bought one earlier and cannot buy one unless he has checked its availability. Non-functional Requirements These are quality requirements that stipulate the performance levels required of the system for various kinds of activities. Numerical lower and upper limits set conditions on the response times, access times etc of the system. Sometimes, tradeoffs are necessary among various non-functional requirements. Future Requirements As technology improving day to day,users needs are also increasing.so we have to update our applications time to time in order to satisfy the customers.These are the specifications which are not provided for now in the current version of ARS but which could be incorporated into future versions. Some of these need advanced technologies and interfaces with other systems. The ARS could be designed in future to enhance the existing capabilities or add entirely new ones. The assumptions and limitations of the ARS have been interspersed in the SRS to present the same in their proper context. REQUIREMENTS ANALYSIS DOCUMENT 1. System Objectives 1.1 The Airline Reservation System (ARS) is a software application to assist an airline with transactions related to making ticket reservations, which includes blocking, reserving, canceling and rescheduling tickets. 1.2 From the viewpoint of the airline 1.2.1 Minimize repetitive work done by the system administrator and reservation clerks. 1.2.2 Maintain consistency among different access modes, e.g. by phone, by web, at the information desk and across different physical locations. The users should be basically taken through the same steps by the system as they go through in conventional desk-reservation systems. 1.2.3 Maintain customer information in case of emergency, e.g. flight cancellation due to inclement weather. The profile can also be used by the airline company to track user preferences and travel patterns to serve them better, plan routes, for better marketing and efficient scheduling of flights. 1.2.4 Maximize the revenue of the airline company by various means: 1.2.4.1 Increase awareness among frequent travelers about various special offers and discounts. 1.2.4.2 Minimize the number of vacant seats on a flight and maximize flight capacity utilization. 1.2.4.3 Maintain the capability to adopt a flexible pricing policy. The price of the tickets should be dynamically determined based on how early, before the date of departure, the customer buys the ticket. 1.3 A survey conducted by airline companies shows that users of an existing reservation system would respond favorably to an ARS that satisfied or helped them satisfy the following objectives: 1.3.1 Reduce effort and frustration for travelers in scheduling a trip, especially by reducing the search effort for the flight they need to take. 1.3.2 Show all possible combinations and itineraries available for a pair of origin-destination cities. 1.3.3 Reduce redundancy in the information required from the customers in order for them to buy tickets, create user accounts etc. 1.3.4 Check the validity of input data and give a feedback to the user in case of errors or inconsistency. 1.3.5 Provide flexible access modes to users internet, telephone, PDA. 1.3.6 Protect customers privacy concerns. 1.3.7 Make it easy for travelers to check the ticket status or make changes to their trip. 2. System Context 2.1 The ARS will provide the following types of easy-to-use, interactive, and intuitive graphical and telephonic interfaces. 2.1.1 The ARS will provide an easy-to-use, intuitive Graphical User Interface (GUI) as part of the Clerk/Administrators working desktop environment. 2.1.2 The ARS will also provide an interactive GUI, on the World Wide Web for the general customers. The above two ARS interfaces shall help provide the following functionalities to the users access to the ARS to check the flight schedule, availability of seats, ticket price and to block, reserve, cancel, and reschedule tickets. The ARS will also provide an easy-to-use, simple telephonic user interface, which can be accessed by the customers through telephone or cell phone from anywhere. This interface shall provide access, only to the following functionalities, namely, check flight schedule and check ticket status including any change in the flight timings. The functionality available through this telephonic interface is limited because of security constraints. 2.2 The system and its environment and the interactions between them are depicted in the diagram below. DB-Reservations Flight Schedule Database Customer Via Web DB-User DB-Schedule I N T E R F A C E CW DB-Geography ARS software INTERFACE Cp Customer Via Phone INTERFACE A Administrator The closed boundary above clearly delineates the system and the environment. The diagram shows the interactions between the ARS software and the databases inside the system. There are three databases internal to the system and which the system maintains. DB-user is the database containing all the personal information of the registered users of the ARS. This can be updated by the user by logging in to the system. Information from this database is used during transactions like charging the credit card etc. DB-schedule is a copy of the flight schedule database. The latter exists independently and is updated by a flight scheduler system which is out of scope of the ARS. DB-schedule is updated with the latest status of the flight schedule database whenever there is any change in the latter. For example, if a flight has been added to the schedule between two cities on Tuesdays, DB-schedule gets updated with this change through a process with which we are not concerned. It is external to th e system and is out of the scope of this SRS. DB-schedule also contains the base prices of tickets for various flight numbers. DB-reservations are a database containing information regarding the number of seats available on each class on different flights. It has provision for marking how many of the reserved seats have been blocked but not yet bought. DB-reservations should update itself using DB-schedule, for example, if a new flight is added. DB-geography is a database, which contains information about the cities and towns serviced by the airline. The distance between all cities and towns is contained in a matrix form. There are three interfaces, one for the administrator, one for the customer via web and another for the customer via phone. The administrator can update DB-schedule with any changes in the base prices of flight tickets. The system uses a pricing algorithm and dynamically determines the actual price from this base price depending on the date of reservation vis-Ã  - vis date of departure. The customer interfaces (web and phone) enable multiple functions which are described in the following section section 3. 3. Functional Requirements User Accounts Registration and creation of user profile Checking Availability Making Reservations/Blocking/Confirmation Confirm Ticket Reschedule Ticket Cancellation Update Profile View Ticket Status Query Flight Details Telephone access User Accounts The passenger, who will henceforth be called the user, will be presented with 3 choices by the reservation system, as the first step in the interaction between them. A user can choose one of these and his choice would be governed by whether he is a guest or a registered user and whether he wants to check the availability of tickets or also block/buy them. The terms registered user and guest are described below. A user who has traveled by the airline earlier would have been given a user id and a password. He would have his personal information stored in the database referred earlier as DB-user. This personal information would be henceforth referred to as profile. Such a user with a profile in DB-user shall be called a registered user. A registered user will be able to check the availability of tickets as well as block/buy a ticket by logging into the system. A new user, on the other hand, would either have to register himself with the system by providing personal information or log into the system as a guest. In case of a, the new user becomes a registered user. In case of b, the new user would remain a guest. A guest can only check the availability of tickets and cannot block or buy tickets. But a registered user can also act as a guest if he only wants to check the availability of tickets. Availability of tickets always refers to viewing the flight schedule for given days, the price of tickets and any discount offers. The system shall present the user with an option to exit from the system at any time during the following processes. Registration and creation of user profile The system shall require a user to register, in order to carry out any transactions with it except for checking the availability of tickets. It will ask the user for the following information at the least a user id, a password, first name, last name, address, phone number, email address, sex, age, preferred credit card number. The system will automatically create a sky miles field and initialize it to zero in the users profile. Checking Availability After logging in a user (either a registered user or a guest), the system shall request him to enter the following details origin city and destination city. City is a generic term and refers to a city or town as the case may be. The origin and destination cities would be entered as text. The system shall now refer to the flight schedule database, referred to as DB-geography earlier, and check if there is any ambiguity with the names of the cities. In case there are more than two cities with same name as entered by the user, the system shall list all of them (with more qualifications) and ask the user to select one of them. In case, either the origin or destination cities are not listed in DB-geography as being directly serviced by the airline, the system shall suggest the nearest city to which service is available, including the distance of the destination city from this nearest city. After the origin and destination cities are ascertained, the system shall now access the flight schedule database, referred to as DB-schedule , and checks if there is a direct operational service between the two cities. If not, the system shall suggest possible routes and transfer points using a route selection algorithm. The user shall now be presented with a choice of either selecting one of the routes. In case he selects a route, the system shall fill in the intermediate stop over points and create a multiple trip itinerary for the user. The system shall now ask the user to enter the following details class, one-way or round trip, departure date and the number of adult passengers, children and senior citizens. Class refers to business class/first class/club class/smoking/non smoking. This choice shall be made by the user through a drop down menu indicating all the possible combinations of choices. One-way/round trip shall be either a drop down menu or a check box selection. Departure date refers to either a single date or a range of dates, entered through a calendar-like menu. This menu shall not show dates in the past or those dates that are too ahead in the future(as determined by the airline policy). In case, the trip is a round trip, the system shall also ask the user to enter the departure date on the return trip. Having taken all the above input from the user, the system checks for any false entries like the departure date on the return trip being earlier than the departure date on the onward trip. In case of incompatibility, the system shall display a suitable error message and prompt the user to enter the information correctly. Having taken all of the information ,the system shall now access the flight schedule database DB-schedule and queries it using the input provided by the user. The system queries the reservation database DB-reservations to check which of the flights on the schedule have seats available. The system displays the results in a suitable form (a tabular form) with the following information depicted for each flight number the flight number, departure time in origin city, arrival time in destination city, the duration of the flight (taking into account the possibility of a change of time zone) and the number of seats available on that flight. There can be several flights between two cities and all of them will be listed for the particular date that the user wants to depart from the Origin City. In case, the user has entered a range of dates, the system shall display all the flights for all those dates in the range. If the user has requested a round trip, the system shall display two tables one for the onward trip and one for the return trip. There will be a check box in front of each line in the table representing a flight with available seats. The user is now asked to check one of the boxes reflecting a choice of a flight number and time. In case of a round trip, the user is asked to check one box each in the two tables. The system shall now display the price of the ticket for the trip. This will be the sum of the prices for all the members of the travel party being represented by the user. The system shall also list any rules regarding the cancellation of tickets what percentage of the price will be refunded within what date ranges. This will be displayed as a table. Making Reservations/Blocking/Confirmation After having taken the user through the, Checking Availability, The system will now ask the user if he wishes to block/buy the ticket. If yes, and if the user has been a guest, he will have to first register and become a registered user and then log onto the system. If the user is already a registered user, and if he has logged on already, he can block/buy the ticket, but if he has been acting as a guest, he will have to log on. Having ensured that the user is logged on validly according the system compares the departure date with the system date. If the departure date falls within 2 weeks of the system date, the system informs the user that he has no option to block the ticket and asks him if he would like to buy it. If the difference between the departure date and system date is more than 2 weeks, the system asks the user if he would like to block or buy the ticket. The system informs the user that he can block the ticket at no cost now. It also informs him that if he chooses to block the ticket, he should make a final decision before 2 weeks of the departure date. The system shall send an email to the user, 3 weeks before the departure date as a reminder, in case he decides to block the ticket now. Having taken the input from the user, the system shall now proceed to update the reservation database DB-reservation. It will decrement the number of available seats on the particular flight for the particular class by the number of travelers being represented by the user. In case of a blocking, the system makes a note of it in the database to be used if the user doesnt turn up before 2 weeks of the departure date. It generates a blocking number and displays it for the user to note down. In case the user buys the ticket, the system accesses his profile and charges the price of the ticket to his credit card number. It simultaneously generates a confirmation number and displays it to the user for him to note down. The ticket has been reserved. It adds the mileage of the trip (accounting for the number of travelers) to the skymiles in his profile. Confirm Ticket A user who has earlier blocked a ticket after going through the previous steps required to either confirm the ticket before two weeks of the departure date or the ticket stands cancelled. To let the user confirm a ticket, the system shall first log him on and ask for his blocking number. Then it accesses DB-reservation and removes the check mark, which so far represented a blocked seat. The seat is now confirmed and reserved for the user. The system accesses DB-user and charges the price of the ticket to the credit card number of the user. It simultaneously generates a confirmation number and displays it for the user to note down. The ticket has been reserved. It adds the mileage of the trip (accounting for the number of travelers) to the skymiles in his profile. Reschedule Ticket The system shall present the user with an option to re-schedule his travel partys trip. In order to do this, the system first logs on the user and requests his confirmation number. It will not allow a user to reschedule a blocked ticket but only a confirmed ticket. Using this, it queries DB-reservation and presents the details of the trip to the user, including but not limited to origin city, destination city, date of departure and date of arrival (in case the trip is a round trip). The system shall now ask the user to select new dates from the calendar-menu. In case, there are no available tickets for the dates entered, it displays a suitable message informing him that rescheduling to that date is not possible. In case there are tickets available, the system asks the user to select the flight number for the trip (another for the return trip if the trip is a round trip) and proceeds to update the database. The system accesses DB-reservation and decrements the number of available seats on the flight(s) by the number of members in the users travel party. It then increments the entry for the previous flight by the same number to reflect an increase in the available seats on it as a result of the rescheduling. The system now checks if there is any difference in the prices of the tickets. If so, it accesses DB-user and charges or credits the credit card as the case may be. The system generates a new confirmation number and displays it to the user. Cancellation The system shall also give the user an option to cancel a confirmed ticket or a blocked ticket. The latter case is simpler and will be dealt with first the system shall first log on the user and request the blocking number. Then it accesses DB-reservation and updates it by incrementing the number of available seats by the number of people in the users travel party. In the former case, i.e., for a confirmed ticket, it asks for the confirmation number and accesses DB-reservation and presents the details of the trip. It then lists the applicable rules for cancellation of tickets and depending on the system date and the departure date, it displays the % of the amount that would be refunded if the user cancels the ticket. After the user cancels the ticket, the system generates a cancellation number and displays it for the user to note down. It accesses DB-reservation and updates it by incrementing the number of available seats on that flight by the number of travelers in the users party. It accesses DB-user and credits the refund amount to his credit card number. The system then deducts the mileage of the trip (taking into account the number of travelers in his party) from the sky miles in his profile. Update Profile The system shall enable the user to update his profile at any time. Changes can be made in fields including but not limited to address, phone number and preferred credit card number. View Ticket Status The system shall allow a user to view all information about his trip. After logging him on, it asks for his blocking number or his confirmation number. It accesses DB-reservation and retrieves the details of the trip and presents them to the user in a convenient format, including any last minute changes to the flight timings etc. Such changes will be highlighted. Query Flight Details The system shall allow any user (registered or non registered) to access the details about the arrival and departure times of a flight by requesting the user to input the flight number and date. The system accesses DB-schedule and presents the time of arrival and departure. Telephone access The system shall be accessible through a touch-tone telephone. The telephonic interface shall, at the least, provide the customer with the facility to check availability of tickets and query flight details. The system shall walk the customer exactly through steps 3.3 and 3.9 respectively but through a telephonic interface. Non-functional Requirements Performance Response time of the Airline Reservation System should be less than 2 second most of the time. Response time refers to the waiting time while the system accesses, queries and retrieves the information from the databases (DB-user, DB-schedule etc) (A local copy of flight schedule database is maintained as DB-schedule to reduce this access time) ARS shall be able to handle at least 1000 transactions/inquiries per second. ARS shall show no visible deterioration in response time as the number of users or flight schedule data increases Reliability ARS shall be available 24 hours a day, 7 days a week ARS shall always provide real time information about flight availability information. ARS shall be robust enough to have a high degree of fault tolerance. For example, if the user enters a negative number of passengers or a value too large, the system should not crash and shall identify the invalid input and produce a suitable error message. ARS shall be able to recover from hardware failures, power failures and other natural catastrophes and rollback the databases to their most recent valid state. Usability ARS shall provide a easy-to-use graphical interface similar to other existing reservation system so that the users do not have to learn a new style of interaction. The web interface should be intuitive and easily navigable Users should be able to understand the menu and options provided by ARS. Any notification or error messages generated by ARS shall be clear, succinct, polite and free of jargon. Integrity Only system administer has the right to change system parameters, such as pricing policy etc. The system should be secure and must use encryption to protect the databases. Users need to be authenticated before having access to any personal data. Interoperability ARS shall minimize the effort required to couple it to another system, such as flight schedule database system.

The Negative Aspects of Animal Experimentation Essay -- Ethical Issues

Imagine your dog, your cat, or even your favorite animal being hit by a car. The tests that animals are put through during research are not much different. Every year millions of animals are forced to endure pain and suffering while being put through cruel and unnecessary tests (Newkirk 1). Animal experimentation should be illegal because there are other options for research, it is cruel and unfair to the animals, and because the results are not always accurate. There are several other ways to conduct experiments that do not use animals. Instead human tissue and living cells can be used to test new drugs and their chemical toxicity (Hayhurst 36). The cell cultures are placed in test tubes, assay plates, or other experimental containers and injected with a small amount of a drug. The cells create an artificial environment exactly like the environment inside a human’s body. Organs from humans or animals can also be used along with bacteria, fertilized chicken eggs, and from embryos (Day 98-99). Animal cells are more commonly used for testing than human cells are. Some human cells cannot be cultured in labs. Also there is a limited supply of cells from humans. The human cells used only come from tissue that is left over from surgery or from cadavers. A single animal can supply a large amount of cells as well as many different kinds of cells. These cells can be used for toxicity testing and to evaluate the risk of the drug. When cell cultures are used the dosage required is only a very small amount, which prevents the drug from being wasted. The dosage can also be carefully controlled and measured resulting in more accurate data (Day 99). Organ cells can be used to predict toxicity in target organs such as the l... ...drug had been given to mice, rabbits, rats, and monkeys, and all of them showed no bad effects (Allen 1). Within minutes the volunteers were writhing on the floor in agony. The drug was designed to dampen the immune response, but instead it supercharged theirs, unleashing a cascade of chemicals. All six of them were sent to the hospital. Several of them suffered permanent organ damage. One man’s head swelled up so badly that the case was referred to as the â€Å"elephant man trial† (Allen 1). Every year millions of animals are used to test products before they are used on humans. People use these products without thinking about the animals that the suffered and died for their benefit. They are selfish, and they never stop to think about the other options for testing, the cruelty of the experiments, or whether or not the test results are even accurate.

Sarkar-Singer Hypothesis Essay -- International Trade

Sarkar-Singer Hypothesis Introduction Since terms of trade deterioration hypothesis was proposed by Prebisch and Singer in 1950, comparative advantage was doubted. Due to the export structure of developing countries (DCs) is dominated by primary products, and the export structure of industrialised countries (ICs) dominated by manufactured products; they compared primary products export of DCs and manufactured products export of ICs, and indicated that the terms of trade trend to deteriorate over time. This hypothesis is supported by many studies, such as Grilli and Yang (1998) and Spraos (1980); therefore the widening gap like existed. This hypothesis is confronted the traditional view, international trade and specialisation may not be better off. The Prebisch-Singer hypothesis also impacts on the trade policy of the majority of DCs to become inward looking. However, many studies appeal that the defected of Prebisch-Singer hypothesis, Sarkar and Singer analysis is the important appeal. Due to Singer (1958) views that the export structure of the DCs was dominated by primary products; export structure of the ICs by the manufactured products. Therefore, theearly studies use the terms of trade between primary products and manufactures as a proxy. Sarkar (1986) express that the growth of manufactured sectors, however, Singer (1987) proposes that even the change in the commodity composition of exports, the disadvantages in DCs lead the deterioration be continuous. Sarkar and Singer (1991) focuses on this subject, examines the impact of the shift in the commodity composition of exports of DCs. They proposed that the changes in commodity composition of exports are the important factor, as the primary sectors of DCs have a lower rat... ...ent, Vol. 19, No. 4, Page 333-340 Singer, H. W.

Philosophy †Free Will vs. Determinism Essay

The dialogue between philosophers over the existence of free will versus the inevitability of determinism is a debate that will always exist. The discussion centers around the true freedom of humans to think and act according to their own judgment versus the concept that humans are intrinsically bound by the physical laws of the universe. Before I enter this chicken and the egg debate I need to quantify my terms: Free will is defined by the great philosopher, St. Thomas Aquinas as â€Å"vis electiva† or free choice. It is the ability of man to contemplate and judge the effects of the actions he is about to take. â€Å"†¦But man acts from judgment, because by his apprehensive power he judges that something should be avoided or sought. But because this judgment, in the case of some particular act, is not from a natural instinct but from some act of comparison in the reason, therefore he acts from free judgment and retains the power of being inclined to various things. † (Aquinas. Suma Theologica) Determinism is a complex notion but is best described by David Hume as the notion that something cannot come from nothing and that all actions have causes preceding them. â€Å"I conceive that nothing taketh beginning from itself, but from the action of some other immediate agent without itself. And that therefore, when first a man hath an appetite or will to something, to which immediately before he had no appetite nor will, the cause of his will, is not the will itself, but something else not in his own disposing. So that whereas it is out of controversy, that of voluntary actions the will is the necessary cause, and by this which is said, the will is also caused by other things whereof it disposeth not, it followeth, that voluntary actions have all of them necessary causes, and therefore are necessitated. † (Hume. Liberty and Nessessity. ) Philosophy and world religion alike were born of the same origins. Each of the two ancient disciplines arose from the quest for the answers to life’s ominous questions. These human questions, archetypical to people of all geographic locations; where did we come from; why are we here; where do we go when we die; unite us as a race. It is no coincidence that each religion and theology from all four corners of the earth tackles these black holes of human logic. Each religion carves their own individual explanations of these unanswerable questions into their core belief systems, each one centrally different than others. However, they all share one common thought; each shares a belief in an afterlife determined by the choices made in life. Free will is the common denominator in all world religions, because all share the essential concept of morality. The widespread acceptance of the concept of morality implies that there is a choice to be had at each and every juncture or life. The choice comes from recognition of good and evil. For good and evil to exist, then there has to be the ability to decipher between the two and also decide to accept one over the other. The existence of morality alone proves that free will exists, because without the freedom to choose right or wrong in any given situation there would be no qualitative measure of the â€Å"rightness† or â€Å"wrongness† of ones actions. David Hume comments on the origin of morality and its place in our everyday decision making processes, â€Å"Only when you turn your reflexion into your own breast, and find a sentiment of disapprobation† (Hume.Treatise of Human Nature). In other words, there are no outside stimuli that can decipher good from evil; the line can only be drawn by internal thought. Hume was a naturalist in that his vision of the world and therefore stance of philosophy was based directly through the experiences of the senses. His stance on many issues directly originated from his ability to experience it with the five senses, and on the subject of morality he takes exception. Even he recognizes the existence of morality in everyday life, even though it cannot be explained through the lens of the senses. It would seem that morality’s acceptance must therefore prove that free will exists, but there is one essential school of thought yet to weigh on this topic; science. Science was the latest bloomer of the three major disciplines of existential explanation and in the post modern era is becoming more and more popular. As the world becomes further secularized and the reaches of scientific logic continue to exceed their grasp, many of the world’s intellectuals identify â€Å"truth† on a scientific scale. Science does not support the theory of morality, because it can’t be proven to exist. The notion of â€Å"free-will†, something which world religion and philosophies alike recognize as a fundamental part of our human anatomy, is called into question in a few simple and logical ways. Science supports the theory of determinism as the only logical explanation of the unfolding of the actions of our lives. First off, science has recently developed the discipline known to us as physics, in which the laws of the universe have been defined. In the short time in which humans have been graced by the scientific understanding of the laws of the universe, human kind has yet to fully step back and contemplate the magnitude of this discovery. In generations past, humans believed that we were made special with â€Å"free will†, but now we know that like all things in the universe we are subject to the physical laws. This is a huge step forward in rational thinking because it allows us to understand that our previously God given concept of â€Å"free will† was really a result of a lack of understanding of the deterministic laws of the universe. For instance a law as simple and commonly accepted as â€Å"gravity† challenges the idea of free will. Gravitational pull determines that no matter the size of an object, once separate from the surface of the earth will be dragged back down at the same force every time. This is a simple concept that we take for granted, but it works in the free will v. determinism argument. We are ruled by gravity, and therefore all of our lives activities answer to it. We can’t choose to jump off a building and float in the air because we’ll be pulled back to the ground to our imminent deaths. We can’t choose to stay younger and keep our skin tight to our faces because gravity’s long-term effect causes our skin to droop down towards the ground. The choices I just listed may seem farfetched to some, however, if we examine the notion that we have â€Å"free will† in the empirical sense of the word we see that not all of our decisions are controlled by us, and that we fall victim to the tyrannical rule of the physical laws of the universe. We aren’t truly â€Å"free† to create our own actions in life. Albert Einstein offers a particularly apt synopsis, â€Å"Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect as well as the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper. † (Albert Einstein) The rule of physical law aside, which hinders us from truly being â€Å"free† to choose our own actions in life, is a much more simple scientific argument that dispels the notion of free will. For example: Say a 20 year old man murders another man in cold blood. They have no affiliation, no prior knowledge of who each other is, or reason to dislike each other. Man A walks up to random Man B and shoots and kills him. Was this action of Man A a result of â€Å"free will†? To examine the notion fully you need to look at his action coming from two sources. Either Man A was born with the moral flaw to allow himself to find killing another human acceptable, or that Man A was influenced during the course of his life by interactions and actions of others and came to that conclusion based on his own experience. There is no other explanation for Man A to willingly choose to open fire on Man B and kill him. If we look at the first option, Man A’s natural moral compass was skewed, allowing for him to conceive the notion that killing another is okay. This speaks to the determinant nature of our chemical makeup. Its possible his DNA made a mistake coding somewhere and he developed overtime and understood that killing another is â€Å"wrong† or maybe that his entire sense of â€Å"right from wrong† was skewed inside his mind. This would lead Man A to lead a life normally on the outside, and yet without regard for consequence, open fire on another man and kill him as easily as he could have held a door for him. This is the idea that he naturally had the capacity to kill, and that he could not control it. Eventually one of his animalistic impulses would finally stick and he’d be in the right place at the right time, and that it was only a matter of time until he killed someone. If you don’t subscribe to that theory and believe that he chose to kill Man B that day, try and consider that the results will still be pre-determined. If Man A killed Man B due to his choice, then his own â€Å"free will† and judgment that he finds reprehensible to kill another man can’t be attributed to truly â€Å"free† will of choice. Not every human kills others as part of their natural lifestyle, as they might kiss or mate with another. In fact a very small percentage of people in the world murder other humans, and this begs the question of why? What makes this small percentage of people â€Å"choose† to kill another person? The answer is that if they choose to do it, and they weren’t previously miswired so as said in the prior paragraph, then they must have been influenced by their surroundings. When Man A was six years old he didn’t choose to murder Man B, the events of his life led him to make this decision about whether or not murder was okay. This is yet another reason that he wasn’t truly free to choose; outside influence hinders the ability to choose freely. Whether he was abused, molested, lost a loved one, or just plain fed up with the monotony of everyday life in society, something pushed him over the edge. Something allowed for him to justify his actions; that something is outside influence. This deterministic train of thought explains why people do what they do, but not when. What makes us actually hit the point of no return, or when will the right opportunity hit the right mood leading the right action? (In our example the murder of Man B) The paradox between â€Å"free will† and â€Å"determinism† exists because of the influence of the different schools of thought. If one aligns his personal truth based on religious fervor, then an understanding of â€Å"free will† can exist logically and on the other hand if one bases his logic around science then â€Å"determinism† seems to be the only answer. So where does that leave philosophy, the great bridge between the two polarized schools of thought? It leaves philosophy somewhere in the middle, examining the validity of both sides of the argument, and helping to shed light on the debate over whether or not we truly are free to make a choice or if we are merely floating along the currents of the universe. Personally, I’m lost somewhere in the middle, hoping that the answer to this time-old question will be revealed. Works Cited: * Aquinas, St. Thomas.

The Business Ethics Field of Study

The business ethics field of study has evolved through five distinct stages. These stages are before 1960, the 1960s, the 1970s, the 1980s, and the 1990s. It also continues to evolve in the twenty-first century. With each stage come new changes. In the last 30 years the ethics field of study, starting from the 1980s, has shown multiple changes. In 1980 business ethics was acknowledged as a field of study. A group of institutions with diverse interests promoted its study causing business ethics organizations to grow and include thousands of members.The 1980s also brought forth the development of the Defense Industry Initiative (DII) on Business Ethics and Conduct. This Defense Industry Initiative includes six principles. These six principles are as follows: 1. Supports codes of conduct and their widespread distribution 2. Member companies are expected to provide ethics training for their employees as well as continuous support between training periods. 3. Defense contractors must crea te an open atmosphere in which employees feel comfortable reporting violations without fear of retribution. . Companies need to perform extensive internal audits and develop effective internal reporting and voluntary disclosure plans. 5. DII insists that member companies preserve the integrity of the defense industry. 6. Member companies must adopt a philosophy of public accountability. Another change that occurred during the 1980s was the lift of many tariffs and trade barriers, and businesses merged and divested within an increasingly growing atmosphere.The fourth distinctive stage of the business ethics field that brought change over the last 30 years is the stage 1990s. In the 1990s Congress approved the Federal Sentencing Guidelines for Organizations. This set the tone for organizational ethical compliance programs in the 1990s. The guidelines broke new ground by codifying into law incentives to reward organizations for taking action to prevent misconduct such as developing eff ective internal ethical and legal compliance programs.Under the Federal Sentencing Guidelines for Organizations if a company lacks an effective ethical compliance program and its employees violate the law, they can incur severe penalties. The final change of the business ethics field that occurred in the last 30 years is from the twenty-first century. In 2002 Congress passed the Sarbanes-Oxley Act to try and improve ethical standards in business. This new act made securities fraud a criminal offense and stiffened penalties for corporate fraud. It also requires corporations to establish codes of ethics for financial reporting.In 2004 there was an amendment to the Federal Sentencing Guidelines for Organizations that requires that a business’s governing authority be well informed about its ethics program with respect to content, implementation, and effectiveness. All of these changes from the last 30 years have institutionalized the need to discover and address ethical risks. Th e twenty-first century brought forth changes but also has challenges too. I think the biggest challenge to business ethics in the twenty-first century is the fact that not all business managers and executives have high ethical standards.Fraud is something that happens quite frequently in this century and it’s very unfortunate. There seems to be an increasing number of businesses that need to improve their ethical standards and offer more training to prevent this. Business ethics is something that every company needs to take seriously and really enforce within their employees. It will not only contribute to loyalty and employee commitment, but it will also contribute to customer satisfaction and profit
