Computer Crime Essays (3095 words) - Software, System Software

Computer Crime Computer Crime It's the weekend, you have nothing to do so you decide to play around on your computer. You turn it on and then start up, you start calling people with your modem, connecting to another world, with people just like you at a button press away. This is all fine but what happens when you start getting into other peoples computer files. Then it becomes a crime, but what is a computer crime really, obviously it involves the use of a computer but what are these crimes. Well they are: Hacking, Phreaking, & Software Piracy. To begin I will start with Hacking, what is hacking. Hacking is basically using your computer to Hack your way into another. They use programs called scanners which randomly dials numbers any generating tones or carriers are recorded. These numbers are looked at by hackers and then used again, when the hacker calls up the number and gets on he's presented with a logon prompt, this is where the hacking really begins, the hacker tries to bypass this anyway he knows how to and tries to gain access to the system. Why do they do it, well lets go to a book and see Avid young computer hackers in their preteens and teens are frequently involved in computer crimes that take the form of trespassing, invasion of privacy, or vandalism. Quite often they are mearly out for a fun and games evening, and they get entangled in the illegal use of their machines without realizing the full import of what they are doing, I have a hard time believing that so lets see what a hacker has to say about what he does Just as they were enthraled with their pursuit of information, so are we. The thrill of the hack is not in breaking the law, it's in the pursuit and capture of knowledge., as you can see the hacker doesn't go out to do destroy things although some do. It's in the pursuit of knowledge. Of course this is still against the law. But where did all of this start, MIT is where hacking started the people there would learn and explore computer systems all around the world. In the views of professional hacking is like drugs or any other addictive substance, it's an addiction for the mind and once started it's difficult to stop. This could be true, as hackers know what they are doing is wrong and they know odds are they will be caught. But as I mentioned some hackers are just above average criminals, using there skills to break in banks and other places where they can get money, or where they can destroy information. What a hacker does at a bank is take a few cents or even a few fractions of a cents from many different accounts this may seem like nothing but when all compiled can be alot. A stick up robber averages about $8,000 each job, and he has to put his life and personal freedom on the line to do it while the computer hacker in the comfort of his own living room averages $500,000 a job. As for people destroying information, this is for taking some one down, destruction of data could end a business which for some is very attractive. It can cost a company thousands of dollars to restore the damage done. Now that you have an understanding of what a hacker is, it time to move on to someone closely associates with a hacker. This is a Phreak, but what is that. For the answer we turn to the what is known as the Official Phreakers Manual Phreak [fr'eek] 1. The action of using mischievous and mostly illegal ways in order to not pay for some sort of telecommunications bill, order, transfer, or other service. It often involves usage of highly illegal boxes and machines in order to defeat the security that is set up to avoid this sort of happening. [fr'eaking] v. 2. A person who uses the above methods of destruction and chaos in order to make a better life for all. A true phreaker will not go against his fellows or narc on people who

Everglades Flooding Essays - Everglades, Free Essays, Term Papers Everglades Flooding The Everglades: Florida's Dying Natural Wonder Perhaps we take it for granted that our beautiful homeland will be forever changed because of the effects of modern civilizations. The environment, local animals, plants, and neighboring niches are all being affected by a few factors. The insensitivity of humans towards our fellow living creatures has caused the Everglades to shrink dramatically in the last one hundred years. The health of the everglades has been compromised because we as humans need more space to live on, bigger roads, and adventures on which we embark. In the following paragraphs, I will explain one of the most threatening factors to Florida's Everglades, habitat loss. Originally, the Everglades consisted of nearly 8,100 square miles, now, it has been reduced to about 2,300 square miles of which about three-fifths is in set-designated water conservation areas. Two-thirds of the original everglades is the water that falls on one-thirds of the original watershed. In simpler terms, the water in the Everglades is being washed into the ocean at a faster rate than the animal and plant life can adapt to. If this problem continues on the same route it is on, the death toll of animals and plants will reach catastrophic proportions. Many years ago, the Everglades was much deeper than it is now and the wet season lasted many months. Now, huge amounts of water come in short intervals and are dried up more quickly than it can be replaced due to drainage. Grasses who survive in deep water are being killed rapidly. Due to the death of these grasses, several species of fish have decreased dramatically in number. The loss of these grasses allows the melalueca to dominate these areas as the supreme species of plants. Fourteen animal species in the everglades are endangered and many more are threatened. The loss of habitat and overcrowding of certain species are disturbing animal population. Since the 1900's, ninety percent of the bird population has died. In 1988 a serious drought left many animal species homeless and many dead. Food loss due to lack of water killed many plant species. By 1989, only 5,000 bird nests and 15 colonies were present in the watershed of the everglades. In only one year, that number dropped to 1,000 nests. As we all know and love, the food web explains how countless animal and plants are co-dependents of each other and how the domino effect can change each and every one of those species. Many conservation efforts have been done to save the everglades, yet they have all failed miserably in a feeble attempt to erase the damage cause by the most abundant predator to any species world wide, mankind. The Everglade Agriculture Area has been set up to enrich the soil in the Everglades, hopefully restoring the animal and plant life to the original numbers that they used to be. When the water levels plummet and new nutrients are added, the soil is exposed to large amounts of oxygen. This speeds up the bacterial growth and can further harm plant life. The soil can then turn to fine dust and lower the water level several feet. Another effort to save the everglades it to kill the melalueca trees, which suck up large quantities of water. Cutting down the trees was first attempted, but that effort further spread the melalueca seeds. Another method was tried, poison. Poisons are being developed to kill small islands of melalueca trees with out harming the neighboring plants. Everyone can agree on one thing, the distribution of melalueca trees in the Everglades by humans is one of the worst ideas to plague the Everglades epidemic. Overall, vast amounts of money have been spent to save the Everglades. The Clinton administration has donated 1.5 billion dollars on conservation efforts. The 13 billion-dollar tourism industry to the Everglades and the Keys has helped with funds for the Everglades Wildlife Fund and other organizations. On average, the amount of money donated per year to Everglade's conservation efforts is about 2 billion dollars. The reason I chose to do this report on the Everglade is because I got an offhand look at how the Everglades is being destroyed slowly. While going on an airboat tour of the Everglades,

Ethics Critique Essay Example | Topics and Well Written Essays - 1000 words - 1

Ethics Critique - Essay Example According to psychological research, moral judgments are shaped by the human mind and behavior (Ross, et al.345). On the same note, moral judgments are influenced by what a person perceives to be right or wrong. In this respect, the issues of ethics moral, norms, and ethics emerge. These three issues vary from one person to another for differentiated reasons, among them individual growth and development, cultural effects, and the impact of the society on an individual. Therefore, based on the work of the mind and the underlying human behavior, a person can make moral judgments that do not necessarily match those that might be made by another person. Psychological research essentially explains how human beings make moral judgments, based on the human mind and behavior (Ross, et al.358). The right or wrong factor at an individual level is accounted for, alongside virtues and ethics that are also based on the human mind and behavior. The link between all the aforementioned variables can help in explaining the thoughts, judgments, or actions that an individual, or society for that matter, undertakes regarding any given situation or condition. In this respect, judgments or actions by human beings can be justified through psychological research. In understanding how human beings act, feel, and think prior to making moral judgments, psychological research factors in a number of variables that influence the whole process. To start with, human beings must be aware of some given form of morals in order to enable them make moral judgments. In other words, they must be in a good position to distinguish between right and wrong. This aspect is shaped by the environment, behavior, culture, and society among other variables. Once the human being is potentially in a position to differentiate right and wrong, the issue of moral

FINAL PAPER Essay Example | Topics and Well Written Essays - 2500 words

FINAL PAPER - Essay Example ating phenomenon to mankind, the very essence of our existence and the ability for an individual to ponder reflectively on his/her life has been a puzzle to all generations, the problems of identity exist because we exist, on the same concept, the problems emanate from our natural awareness and inquisitiveness, firstly, our identity is directly attached to our personhood, but the question arises, what is a person? The answer most probably must mention some several key activities like locomotion and reproduction, Locke argued that a person is an organism that possess mental capability, Descartes, in his famous quote, I think, therefore I am also directly mentions the faculty of thought, but the challenge arises when we cannot prove whether other ‘things’ have similar capabilities as we do, for example cattle that possess locomotive and reproduction abilities, another question ensues with this issue in that we must wonder- do these other ‘things’ think as we do? And if they do, do they possess an identity as we do. Computers are capable of doing analytical tasks at a speed faster than an individual-so, does it think? So with such matters, it is not a simple task to draw a line between a person and a non person. Besides, it is a reasonable question to ask oneself, when does one become a person, and what would cause him to cease to be? If a person is an organism that possesses mental capability, where do we classify the lunatic or a fetus? No wonder there have been very controversial debates on abortion as some perceive a fetus as a non person while others perceive a fetus as a living organism. The debate further boils to when does life (person) begin, at birth or during conception? Personhood therefore can be clearly defined especially after considering other intelligent animals and automated robots and that are capable of imitating almost everything that we can do, unless we accept the common definition that a person is a human being. This definition

Quality Management Assignment - The assignment is based on the Eurocab Essay

Quality Management Assignment - The assignment is based on the Eurocab case study and appendices attached. Study the case and an - Essay Example One way of achieving both efficiency and effectiveness is through quality management which can be done using the total quality management (TQM) model. TQM is an organisational culture devoted to customer satisfaction through an integrated system of tools, techniques and training aimed at the continuous improvement of the products and services offered (Kotler & Armstrong, 2004). As such, this essay seeks to carry out a critique of EuroCab’s current approach to quality and how this compares with Crosby's fourteen point plans. The analysis will highlight the aspects of the plan being implemented as well as outline the points missed. The second part of the essay will look at the extent to which the six sigma methodology can be implemented within the organisation. 1. EuroCab is one of the leading European manufacturers of customised metal cabinets of various sizes and designs. These are sold to different customers to contain, support and securely protect electrical and electronic c ontrol systems from damage. However, the operations of this organisation are geared towards productivity and there are quality concerns since some of the products manufactured do not conform to the expected standards. Quality of a product or service is based on the judgement by the individual or organisation of a particular product with regards to benefits, value or satisfaction that can be derived from using it (Kotler & Armstrong, 2004). Organisations that are concerned about their viability should prioritise the aspect of quality in order to gain a competitive advantage. As noted, the aspect of quality is of concern to Eurocab and this section of the essay seeks to critique the company's current approach to quality and how this compares with Crosby's fourteen point plan. Philip B Crosby is a quality guru and is known for the concepts of â€Å"Quality is Free† and â€Å"Zero Defects. There are four absolutes of quality in his quality improvement process which are: Quality is conformance to requirements, the system of quality is prevention, the performance standard is zero defect and the measurement of quality is the price of non-conformance. Details of quality gurus can be viewed at the Department of Trade and Industry’s website at . His model is comprised of fourteen steps and these are going to be used to analyse the company’s current approach to quality. He suggests that the first step is that management should be committed to a formalised quality policy but in this case, it seems there is no such coordination between the management and the other members of the organisation in other departments. The management is primarily concerned with productivity while at the same time quality related issues are neglected. The blame for any faulty cab is given to the Quality, Manufacturing as well as the Electrical assembly departments. The management does not make follow up on its quality policies to ensure that that there is conformity in the o perations of the organisation as a whole to satisfy the quality needs of the customers as well as the company. The second aspect of Cosby’s 14 steps is the formation of a management level quality improvement team (QIT) with responsibility for quality improvement process planning and administration. As such, it can be noted that EuroCab has

Introduction To Rdbms Oodbms And Ordbms Information Technology Essay

Introduction To Rdbms Oodbms And Ordbms Information Technology Essay The relational model is based on the structure of a database. A database is simply a collection of one or more relations or tables with columns and rows. The use of set theory allows for data to be structured in a series of tables that has both columns and rows. Each column corresponds to an attribute of that relation, while each row corresponds to a record that contains data values for an entity. The main elements of RDBMS are based on Ted Codds 13 rules for a  relational system, the concept of relational integrity, and normalization. The three fundamentals of a relational database are that all information must be held in the form of a table, where all data are described using data values. The second fundamental is that each value found in the table columns does not repeat. The final fundamental is the use of Standard Query Language (SQL). Benefits of RDBMS are that the system is simple, flexible, and productive. Because  the tables are simple, data is easier to understand and communicate with others. RDBMS are flexible because users do not have to use predefined keys to input information. Also,  RDBMS are more productive because SQL is easier to learn. This allows users to spend more time  inputting instead of learning. More importantly, RDBMSs biggest  advantage is the ease with which users can  create and access data and extend it if needed. After the original database is created, new data categories can be added without the existing application being changed. There are limitations to the relational database management system. First, relational databases do not have enough storage area to handle data such as images, digital and audio/video. The system was originally created to handle the integration of media, traditional fielded data, and templates. Another limitation of the relational database is its inadequacy to operate with languages outside of SQL. After its original development, languages such as C++ and JavaScript were formed. However, relational databases do not work efficiently with these languages. A third limitation is the requirement that information must be in tables where relationships between entities are defined by values. Today, the relational model is the dominant data model as well as the foundation for the leading DBMS products, which include IBMs DB2 family, Informix, Oracle, Sybase, Microsofts Access and SQLServer, as well as FoxBase and Paradox. RDBMS represent close to a multibillion-dollar industry alone. To combat the limitations of RDBMS and meet the challenge of the increasing rise of the Internet and the Web, programmers developed object-oriented databases in the 1980s. The main objective of Object-Oriented Database Management Systems, commonly known as OODBMS, is to provide consistent, data independent, secure, controlled and extensible data management services to support the object-oriented model. They were created to  handle big and complex data that relational databases could not. There are important characteristics involved with object-oriented databases. The most important characteristic is the joining of object-oriented programming with database technology, which provides an integrated application development system. Object-oriented programming results in 4 main characteristics:  inheritances, data encapsulation, object identity, and polymorphism. Inheritance allows one to develop solutions to complex problems incrementally by defining new objects in terms of previously defined objects. Data encapsulation or simply encapsulation allows the hiding of the internal state of the objects. Encapsulated objects are those objects that can only be assessed by their methods instead of their internal states. There are three types of encapsulated objects users and developers should recognize. The first is full encapsulation, in which all the operations on objects are done through message sending and method execution. The second is write encapsulation, which is where the internal state of the object is visible only for reading operations. The third is partial encapsulation, which involves allowing direct access for reading and writing for only a part of the internal state. Object identity allows objects of the database to be independent of each other. Polymorphism and dynamic binding allow one to define operations for one object and then to share the specification of the operation with other objects. This allows users and/or programmers to compose objects to provide solutions without having to write code that is specific to each object. The language important to OODBMS is data definition and manipulation language (DDML). The use of this language allows persistent data to be created, updated, deleted, or retrieved. An OODBMS needs a computational versus a relational language because it can be used to avoid impedance mismatch. DDML allows users to define a database, including creating, altering, and dropping tables and establishing constraints. DDMLs are used to maintain and query a database, including updating, inserting, modifying, and querying data. The OODBMS has many advantages and benefits. First, object-oriented is a more natural way of thinking. Second, the defined operations of these types of systems are not dependent on the particular database application running at a given moment. Third, the data types of object-oriented databases can be extended to support complex data such as images, digital and audio/video, along with other multi-media operations. Different benefits of OODBMS are its reusability, stability, and reliability. Another benefit of OODBMS is that relationships are represented explicitly, often supporting both navigational and associative access to information. This translates to improvement in data access performance versus the relational model. Another important benefit is that users are allowed to define their own methods of access to data and how it will be represented or manipulated. The most significant benefit of the OODBMS is that these databases have extended into areas not known by the RDBMS. Medicine, multimedia, and high-energy physics are just a few of the new industries relying on object-oriented databases. As with the relational database method, object-oriented databases also has disadvantages or limitations. One disadvantage of OODBMS is that it lacks a common data model. There is also no current standard, since it is still considered to be in the development stages. Object-oriented database technology is a marriage of object-oriented programming and database technologies. Figure 1 illustrates how these programming and database concepts have come together to provide what we now call object-oriented databases. Introduction to RDBMS OODBMS and ORDBMS Perhaps the most significant characteristic of object-oriented database technology is that it combines object-oriented programming with database technology to provide an integrated application development system. There are many advantages to including the definition of operations with the definition of data. First, the defined operations apply ubiquitously and are not dependent on the particular database application running at the moment. Second, the data types can be extended to support complex data such as multi-media by defining new object classes that have operations to support the new kinds of information. Other strengths of object-oriented modeling are well known. For example, inheritance allows one to develop solutions to complex problems incrementally by defining new objects in terms of previously defined objects. Polymorphism and dynamic binding allow one to define operations for one object and then to share the specification of the operation with other objects. These objects can further extend this operation to provide behaviors that are unique to those objects. Dynamic binding determines at runtime which of these operations is actually executed, depending on the class of the object requested to perform the operation. Polymorphism and dynamic binding are powerful object-oriented features that allow one to compose objects to provide solutions without having to write code that is specific to each object. All of these capabilities come together synergistically to provide significant productivity advantages to database application developers. A significant difference between object-oriented databases and relational databases is that object-oriented databases represent relationships explicitly, supporting both navigational and associative access to information. As the complexity of interrelationships between information within the database increases, so do the  advantages of representing relationships explicitly. Another benefit of using explicit relationships is the improvement in data access performance over relational value-based relationships. A unique characteristic of objects is that they have an identity that is independent of the state of the object. For example, if one has a car object and we remodel the car and change its appearance, the engine, the transmission, and the tires so that it looks entirely different, it would still be recognized as the same object we had originally. Within an object-oriented database, one can always ask the question, is this the same object I had previously?, assuming one remembers the objects identity. Object-identity allows objects to be related as well as shared within a distributed computing network. All of these advantages point to the application of object-oriented databases to information management problems that are characterized by the need to manage: a large number of different data types,   a large number of relationships between the objects, and   objects with complex behaviors. Application areas where this kind of complexity exists includes engineering, manufacturing, simulations, office automation and large information systems. Object-Relational database (ORDBMS) is the third type of database common today. ORDBMS are systems that attempt to extend relational database systems with the functionality necessary to support a broader class of applications and, in many ways, provide a bridge between the relational and object-oriented paradigms. ORDBMS was created to handle new types of data such as audio, video, and image files that relational databases were not equipped to handle. In addition, its development was the result of increased usage of object-oriented programming languages, and a large mismatch between these and the DBMS software. One advantage of ORDBMS is that it allows organizations to continue using their existing systems, without having to make major changes. A second advantage is that it allows users and programmers to start using object-oriented systems in parallel. There are challenges in implementing an ORDBMS. The first is storage and access methods. The second is query processing, and the third is query optimization. Since the development of RDBMS, OODBMS, and ORDBMS, many vendors have extended their systems with the ability to store new data types such as images and texts, and with the ability to ask more complex queries. One rising technique is enterprise resource planning and management resource planning, which add another layer of application-oriented features on top of a DBMS. Included applications come from  Baan, Oracle, SAP, and Siebel. These programs each identify a set of common tasks encountered by a large number of organizations and provide a general application layer to carry out these tasks. More importantly, DBMS have advanced into the Internet and Web Age.  Stored data is widely being accessed through a Web browser. Today, queries are being generated through Web-accessible forms and answers are being formatted using a mark-up language such as HTML. In addition, many vendors and distributors are adding features to their DBMS aimed at making it better equipped for Internet usage. In summary, relational and object-oriented database systems each have certain strengths as well as certain weaknesses. In general, the weakness of one type of system tends to be strength of the other. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. Object Relational Database Management  System  (ORDBMS) is a DBMS or Database Management System akin to a relational database, but with an object oriented database model that allows  custom web development  professionals to combine the database with custom data types. It bridges the gap between relational databases and Object-Oriented Database Management System (OODBMS).   Traditional RDBMS (Relational Database Management System) focused on the efficient management from a limited set of data-types. Object relational DBMS allows  web sites development  experts to combine their own data types and methods.   The limitations of RDBMS have led to the introduction of object-relational database management systems ORDBMS systems occurred in the early 1990s out of research. One of the most notable research projects, the Postgres introduced two products Illustra and Postgre SQL. The mid-1990s saw many commercial products appearing. These included Omniscience, UniSQL and Illustra 2.   Objectives of Object Relational Databases: To bridge the gap between object-relational mapping and conceptual data modeling techniques. To bridge the gap between object oriented modeling techniques (used in programming languages like C++, C# and  Java) and relational databases. Advantages of ORDBMS: Object Relational Database Management Systems ensures large storage capacity, which is an important part in web based  development The access speed is fairly quick. ORDBMSs have massive scalability. ORDBMSs boast excellent manipulation power of object databases. Supports object functionality by adding separate APIs and  server  subsystems Redesigns the database engine completely Supports rich data types by adding a new object-oriented layer. Apart from these benefits, an object relational database management system has some drawbacks. One of the major disadvantages is its incapability for high-speed internet applications. However, ORDBMSs are designed to manage large amounts of information, an important aspect in the  development of website. The IDC opines that the ORDBMS market has the potential to surpass the size of ODBMS in the next couple of years in web based development.

An object relational database is also called an object relational database management system (ORDBMS). This system simply puts an object oriented front end on a relational database (RDBMS). When applications interface to this type of database, it will normally interface as though the data is stored as objects. However the system will convert the object information into data tables with rows and colums and handle the data the same as a relational database. Likewise, when the data is retrieved, it must be reassembled from simple data into complex objects. Performance Constraints Because the ORDBMS converts data between an object oriented format and RDBMS format, speed performance of the database is degraded substantially. This is due to the additional conversion work the database must do. ORDBMS Benefits The main benefit to this type of database lies in the fact that the software to convert the object data between a RDBMS format and object database format is provided. Therefore it is not necessary for programmers to write code to convert between the two formats and database access is easy from an object oriented computer language. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ To define Object-Relational Database Management System (ORDBMS) it is enough to take simple equation: ORDBMS = ODBMS + RDBMS = (O + R) * DB * MS. On a logical level, an ORDBMS is the MS process methods applied for DB data structure, which is complied with O object and R relational concepts. The R relational concept in the context of DBMS is based on the relations in the form of two-dimensional tables of rows and columns. Transformation of queries into relational algebra is the main confirmation that affiliates a database with the relational model. It is prejudice to think that SQL2 language is a single and necessary criterion of RDBMS just as to think that Java is a single language of OO programming. Noteworthy feature of RDBMS is the possibility to process a large mass of the uniform n-element tuples (rows or records) quickly. All necessary for object representation is available in the object DBMS (ODBMS). Often the ODBMS is equated to the OODBMS, namely DBMS integrated with an Object-Oriented (OO) programming language like C++ and Java. The characteristic properties of ODBMS are 1)  complex data, 2)  type inheritance, and 3)  object behavior. These features will be considered below regarding the ORDBMS. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ Complex data creation in most SQL ORDBMSs is based on preliminary schema definition via the user-defined type (UDT). The table remains a most clear form for representation of complex data in any ORDBMS. students id name course first last st031 Jane Hunter Economy Planning st072 Richard White Computers in Engineering The name attribute (or field or column) consists of the first and last attributes. The value of the course attribute is a set of Economy and Planning elements. Such structure is able, for example, for the Informix SQL (http://www-3.ibm.com/software/data/informix/pubs/library/index.html).

Constructors of the simple built-in types, with limitations like CHAR(5), came from SQL2. Is it necessary to define schema before filling a database? Historically, the answer was canonical yes for two reasons. Firstly, the definition of database schema essentially helped to control the type of input data. Secondly, the data type limitation made possible the early DBMSs to organize data with maximal memory and processor efficiency. Nevertheless, development of database schema is a most laborious process. There are a lot of situations related with complex data when precise schema description is not necessary or unreasonably slows project development. Furthermore, both reasons for schema predefinition are no longer valid. Control of input data should be executed by supporting an input form, (e.g., via JavaScript on the Web client side). With the hardware advances in modern database systems, the influence of data type limitation on performance is practically insignificant. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ An object-oriented database management system (OODBMS), sometimes shortened to  ODBMS  for  object database management system), is a database management system (DBMS) that supports the modelling and creation of data as  objects. This includes some kind of support for  classes of objects and the  inheritance  of class properties and  methods by subclasses and their objects. There is currently no widely agreed-upon standard for what constitutes an OODBMS, and OODBMS products are considered to be still in their infancy. In the meantime, the object-relational database management system (ORDBMS), the idea that object-oriented database concepts can be superimposed on relational databases, is more commonly encountered in available products. An object-oriented database interface standard is being developed by an industry group, the Object Data Management Group (ODMG). The Object Management Group (OMG) has already standardized an object-oriented data brokering interface betwee n systems in a network. In their influential paper,  The Object-Oriented Database Manifesto, Malcolm Atkinson and others define an OODBMS as follows: An object-oriented database system must satisfy two criteria: it should be a DBMS, and it should be an object-oriented system, i.e., to the extent possible, it should be consistent with the current crop of object-oriented programming languages. The first criterion translates into five features: persistence, secondary storage management, concurrency, recovery and an ad hoc query facility. The second one translates into eight features: complex objects, object identity, encapsulation, types or classes, inheritance, overriding combined with late binding, extensibility and computational completeness. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦.. http://www.versant.com/en_US/products/oodbms.html/ OODBMS (OBJECT DATABASE) ADVANTAGES Using an  OODBMS  /  ODBMS  (object database management system, object-oriented data management system) for data storage brings powerful advantages to applications that use complex object models, have high concurrency requirements, and large data sets.

Radio B92: Unbiased Civil War Coverage by Serbia’s Own :: Free Essays Online

Radio B92: Unbiased Civil War Coverage by Serbia’s Own Fair and impartial reporting of the Balkan wars in the 1990s was a difficult and lone venture. Almost all of the international media had their own biases due to their countries’ part in the war (through NATO or their proximity to the conflict), their acceptance of parts of Serbian government propaganda, or simply their overly exaggerated partialities against the Serbians because of a common belief that all Serbians were entirely responsible for the war. It is also widely accepted that Bosnia and Serbia’s media, if not influenced or controlled by the government and Milosevic, struggled greatly to remain independent – if that. So, throughout the conflict in the 1990's, Radio B92 was the only independent audio news source. It served as the principal alternative to the government controlled media, especially for the former Yugoslavia, but also to the biased international press. According to Jasminka Udovicki and James Ridgeway, the editors of a book about the fall of Yugoslavia titled Burn This House: The Making and Unmaking of Yugoslavia: It took almost a century, from the emergence of the South Slavic unification movement in the early nineteenth century to the end of World War I, to create Yugoslavia. It took only a few years to destroy it [. . .] Visions of national liberation and modernization brought the South Slavs [. . .] together at last in 1919. Seventy years later, a retrograde, mythical, antimodern vision tore them apart (11). The fall of Yugoslavia was brought about by brutal military force, but the energy needed to utterly dismantle the country was supplied by the political ethno-kitsch (1). An idea emerging here, one expressed by many, is that Yugoslavia may have been alright, or at least far better off and not torn apart if it were not for Milosevic’s means of gaining political power. While these factions did have their differences, they had coexisted for thousands of years before WWI and Tito, the former leader, was able to keep them together. This idea of â€Å"ethno-kitsch† began around 1987, and involved a sort of new taste for an almost vulgar fascination with Serbian nationalism. According to Udovicki and Ridgweway, it, â€Å"was everywhere in Serbia.† At the root of this â€Å"ethno-kitsch† in the late 1980s was a progressively growing perception that Serbian people had been wronged and were hated – completely undeservedly – by other ethnic groups in Yugoslavia.

Budweiser’s Internal Constraints

Budweiser is produced by Anheuser-Busch Companies (Anheuser-Busch), one of the world's largest brewers best known for its Budweiser and Bud Light brands. The group is a leading brewer and operates 12 breweries in the United States (Company Website, 2007). As a company, Anheuser-Busch’s internal constraints are as follows: 1. High dependence on domestic beer division Although the company operates through four business segments including domestic beer, international beer, packaging and entertainment it is still dependant on the domestic beer segment for majority of its revenue.During the fiscal year ending 2006, company generated approximately 74. 8% of its total revenue from the domestic beer segment. In contrast the other three segments accounted for only 25. 2 % of the total revenue during the same period. Strong dependence on a particular segment increases the business risk of the company thereby putting it in a competitive disadvantage (Anheuser-Busch Annual Report, 2006). This is why Anheuser-Busch is currently battling for a presence in China, the world’s largest beer market, as state owned breweries seek foreign help with privatization.In 2004, Anheuser-Busch outbid Miller for the Harbin Brewing Group of China (Modern Brewery Age, Weekly News Edition, June 14, 2004). This year, Anheuser-Busch may acquire Scottish & Newcastle's 37. 5% stake in India-based United Breweries. 2. ) Poor liquidity position Anheuser-Busch has substantial outstanding long-term debt. As of December 2006, the company had long term debt of approximately $7,653. 5 million. The company's debt equity ratio is 2. 2 times which is quite high as compared to industry average of 1. 3 times.The company's interest coverage ratio is 6. 2 as compared to industry average of 10. 1 times (Anheuser-Busch Annual Report, 2006). This ratio clearly signifies that the liquidity position of the company is bad and this would hamper company’s credibility in the market and would be diff icult for them to raise money from the market for their expansion plans. 3. ) High dependence on wholesalers Anheuser-Busch sells substantially all of its beer to independent wholesalers for distribution to retailers and ultimately consumers.During 2006, approximately 94% of the beer sold by the company, reached retail channels through more than 600 independent wholesalers (Anheuser-Busch Annual Report, 2006). In 2007, Anheuser-Busch was appointed as the United States importer for a number of the premium European brands of InBev (International Herald Tribune, 4 February 2008). Many of the wholesalers of these brands have not traditionally been wholesalers for Anheuser-Busch. As independent companies, wholesalers make their own business decisions that may not always align themselves with the company's interests.Dependence of the company on the wholesalers may affect the bargaining power of the company in the market, thus affecting its financial performance.

Message confidentiality Essays

Message confidentiality Essays Message confidentiality Essay Message confidentiality Essay Secret key cryptography is also known as Symmetric Encryption. Here same key is used for both the Encryption and Decryption processes [1]. In this approach, sender and receiver both should know the algorithm to use and the secret key. Sender and receiver should be kept the key secret and they should obtain the key in a secured way [2]. Most commonly used secret key cryptography algorithms are DES, 3DES, RC4 etc [1]. In this test DES has been used to encrypt/decrypt an arbitrary message. Here Base64 encoding has also been used to encode the message. We know that, while sending SMTP e-mails with attachments normal text files can be attached in plain text format, but binary files (such as image files) cannot be attached in the same way. Binary files need some sort of encoding process to be attached with STMP mail. And the most widely used encoding is Base64 [3]. Description of DES algorithm DES Encryption Process DES has a very strong internal structure [2]. The following figure presents an overview of the DES encryption process. Figure 1: DES Encryption process In DES encryption process 2 inputs are provided to the encryption function: a 64 bit plain text and a 56 bit secret key. At first, the 64-bit plaintext is initially permuted. In the next step combination of a permutation and substitution function is executed 16 times, it makes 16 rounds. Left half and right half of the output from the last round are swapped and permuted again. This permutation is an inverse function of the initial permutation function. At last we get a 64 bit cipher text as an output of the whole process [2]. DES Decryption Process DES decryption process uses the same algorithm as DES encryption process. But in this case the application of the subkeys is reversed [2]. Strength of DES The main strength of DES is usage of 56 bit keys. For using 56-bit long keys the number of possible key is 256 and so the bruit force attack needs 255 attempts which is quite impractical to complete. So DES is strong against Brute force attack. It is also strong against Differential Cryptanalysis and Linear Cryptanalysis as they need 247 and 243 attempts respectively [4]. Base64 Data Representation Base64 data representation is based on a 64 character alphabet [3]. The alphabet is presented in the following table. Sequence Characters 0 25 A Z 26 51 a z 52 61 0 9 62 + 63 / Table 1: Base64 Alphabet A binary file is a series of zeros and ones [3]. These bits are represented with a 0 or 1 character. In Base64 data encoding at first the zeros and ones are grouped into sets of 6 characters. Then these blocks of bits are converted by a single character, which can be calculated from table 1. In this way 6 characters are replaced by a single one. Thus Base64 alphabet allows converting binary zeros and ones into a compressed and human readable format [3]. Description of the demo Programming Language Java Java has been used here to implement DES including Base64. Java has been chosen as it has some advantages such as it is open source, platform independent, and it has automatic memory management [5]. Besides, the Java platform has some built in packages that make cryptographic implementation easier. Source code Result of test run The test result was as follows. Conclusion According to Microsoft Confidentiality is the ability to keep a message unreadable by anyone other than the intended recipient; this is achieved through cryptography [6]. So here to achieve confidentiality DES algorithm has been used including Base64 encoding and also have successfully retrieved the original message by using decryption process.

You Have the Right to Remain Silent Animal Rights Vs. The Need for Natural Products

You Have the Right to Remain Silent Animal Rights Vs. The Need for Natural Products Introduction: On the Relationships between People and Nature There is no need to mention the sad fact that the relationships between people and nature, including most of its elements, have been rather complicated, especially since the advent of technological progress and the consequent pollution issues.Advertising We will write a custom essay sample on â€Å"You Have the Right to Remain Silent†: Animal Rights Vs. The Need for Natural Products specifically for you for only $16.05 $11/page Learn More According to the humanist principles, animals must be granted the right to live, as well as the right to be treated in a humane way. However, in the late XX and early XXI century, with the progress of the humanist ideas peaking as they never have before, one of the aspects of the nature-vs.-nurture conflict has become especially debatable. Since in the age of democracy, it has become obvious that every single person has his/her own rights and freedoms, it h as been suggested that the concept of rights must be applicable not only to people, but also to every single living being, i.e., the animal world as well. Therefore, the given idea entails the prohibition of killing animals for the sake of fur, leather or food production (Fudge 75). Although modern technologies allow for creating artificial leather and fur, the problem of substituting meat remains open. Since most people are not ready to become vegetarian, giving animals an indefeasible right to live might be a hasty decision. From One Extreme to Another: From Beyond the Barricades It is worth admitting that both sides of the argument, i.e., the people who believe that animals should be given their indefeasible rights, as well as the people who do not consider it possible to provide animals with rights. To start with, the opinion of the proponents of animal rights crusade should be considered.Advertising Looking for essay on philosophy? Let's see if we can help you! Get your first paper with 15% OFF Learn More The reasons behind the actions of fighters for animal rights are quite simple. According to what the activists like PETA say, animals are living beings; they can feel pain, switch moods, display certain social behavior, and, therefore, must be provided with legal rights (Fox 203). Simple enough the given argument is still very convincing. The opponents of the fighters for animal rights often use the arguments of the latter to prove the point. According to what Cohen and Regan say, â€Å"for the advocates of animal rights in the strict sense, the utilitarian arguments of the ‘liberation’ camp are not only insecure but dangerous. In some cases, at last, the calculations of good and bad consequences of animal use is virtually certain to yield a result not favorable to the animals. But in such cases the liberationist defense of animals must collapse, resting as it does on the calculations of the worth of outcomes† (Cohen and Regan 8). It would be wrong, however, to consider that the arguments of those who are against providing animals with rights are restricted to nitpicking on the ideas of the animal rights proponents. As a rule, the key argument of the people who believe that animals do not need the human concept of rights is that in the animal kingdom, there is no concept of morality. Since rights arise in the sphere of the latter (Cohen and Regan 8), it can be considered that the concept of rights is inapplicable to any element of the animal kingdom, where morality as a notion does not exist and which is ruled by the key principle that only the strong survive (Jasper 170).Advertising We will write a custom essay sample on â€Å"You Have the Right to Remain Silent†: Animal Rights Vs. The Need for Natural Products specifically for you for only $16.05 $11/page Learn More Another argument that the fighters for treating animals like animals provide to the organ izations like PETA is that animals are the only option for testing new medicine or conducting any other scientific experiments. Indeed, given the fact that there is no alternative to testing newly developed medicine on animals, providing animals with such rights as the right to live will ensue a number of murder cases if some of the experiments prove lethal. As a result, the newly created medicine will become less efficient and more dangerous to use, with a number of unpredictable side effects. As Cohen and Regan explain, The animal rights movement†¦ as I conceive it, is committed to a number of goals, including: the total abolition of the uses of animals in science; The total dissolution of commercial animal agriculture; The total elimination of commercial and sport hunting and trapping†¦ You don’t change unjust institutions by tidying them up. (Cohen and Regan 9) Finally, admitting animals to have legal rights will presuppose that animals will be â€Å"consider ed to have legal standing† (Fox 204), which, given the gap between the development of animals and people, is simply absurd. Therefore, the key reasoning provided by the opponents of the animal rights crusaders is that a) the concept of morals is inapplicable to animal world and 2) there is little to no alternative for the use of animals in medicine testing.Advertising Looking for essay on philosophy? Let's see if we can help you! Get your first paper with 15% OFF Learn More My Opinion: Why Sustainable Approach Deserves to Be Applied Personally, I believe that the policy towards animals treatment must be less radical. To be more exact, it must be sustainable. To start with, it is crucial that animals should not be tortured in slaughterhouses and that the process of slaughter should be as quick and painless as possible. In addition, the laws concerning the maltreatment of animals must be revisited so that the people whose pets are being mistreated should be detected and that their pets should be taken to the animal shelter where they will be taken a proper care of. As for marketable fish, game birds, etc., there is no need to stress that people need these products to remain healthy. While protein can be obtained from the sources other than game bird and cattle, phosphorus contained in fish is not easy to replace with the phosphorus from any other sources. That being said, killing animals for the sake of providing people with the necessary minerals and vi tamins is inevitable, and no alternative for the given process has been found to this day (Hester and Harrison). Speaking of animals as resources various materials, such as fur, wool, leather, etc., one must mention that with the technological developments of the XXI century, providing the substitute for fur sand leather is relatively easy, which means that animals should not be used as the sources for various materials anymore. Once adopting the sustainable approach towards wild animals and providing the rules for treating domestic animals and pets in an appropriate way, setting the bar for the concept of â€Å"mistreatment,† one will be able to provide animals with their rights without infringing the rights of people. The Reasons for Holding the Universal Appeal: Why Giving Animals Rights Is not the Most Reasonable Idea The key idea that makes me choose the reasonable (i.e., sustainable) treatment of animals and a humanistic approach towards them instead of providing animal s with the rights that they deserve as much as people do is the fact that the need for animals to have rights comes from people’s concept of the universe. To be more exact, the problem is that these are not animals who demand their rights – these are people who demand rights for animals; the latter are not aware of the concept of rights at all. Therefore, the given situation can be regarded as an attempt to approach the principles of the animal world with the help of human morals, which is intrinsically wrong, seeing how animals do not have the concept of morals. As Fudge put it, Think for a moment about who asserts animals’ rights. Is it a laboratory rabbit, veal calf, or hunted fox? Not at all. Animal rights is exclusively asserted by society and it is intended to restrain human practices. It says that animals are morally the same as humans, and then asks humans to treat them as if they were human; it is up to us to struggle for animal rights because animals c annot fend for themselves. (Fudge 50) Therefore, it is impossible to approach the idea of animal rights from people’s perspective. Truly, in the light of the fact that people are equipped much better than animals, they should be more responsible about the means that they choose to build relationships with nature. However, there is a great difference between acknowledging the weakness of animals and, thus, being more responsible towards the wildlife and claiming that people have no rights to use animals for medicine testing, producing food, etc. Therefore, it is necessary not to be cruel towards animals, yet, unless an alternative for meat and medicine testing is provided, claiming that animals must not be killed will come at a price of many people’s lives. The Possible Objections: What Both Camps Have to Say It must be admitted that both camps will argue against the solution that I have provided. The fighters for animal rights will point at the fact that my solution pr esuppose treating animals as a resource instead of considering them beings with rights. Although the provided solution does allow to avoid cruelty in treating animals, it still fails to recognize their rights for the reasons mentioned above. The supporters of the idea that animals cannot have rights will consider the given solution as restrictive in that it does not allow to satisfy the tastes of people who would like to cater not only on tuna, but also on more exotic types of fish or animals and to enjoy natural fur. Therefore, their key argument may be that the provided solution infringes people’s rights, i.e., cares about animals better than it cares about people. In Response to the Counterarguments: Reasonability and Adequacy The latter argument can be argued by mentioning the fact that, though renewable, a number of natural resources, such as various species of animals, bird and fish, are endangered due to overconsumption. Therefore, it is in the interests of gourmets to abstain from eating exotic animals for a couple of years until certain species replenish their population. Hence, the provided solution takes both the interests of people and animals into account. As for the former argument, biologically, the human race is superior to any other species on the Earth, which means that people as superior beings must take care of animals instead of taking the campaign of animal rights to its absurd point. In addition, the issue concerning medicine testing, unfortunately enough, still remains open, which means that while other solutions are being sought for, animals will be used for experiments.

Native American Music and Dance - Essay Example Powwows, being a cultural display, are meticulously formed depictions, performances, or articulations of Native American past and contemporary reality as they want to express it. Organizing the occasion-- establishing the rules and regulations, registering partakers, and putting in order the activities (Heth 1992)— gives order and furnishes significance to this community gathering. The pan-Indian or supra-tribal feature of the powwow has encouraged scholars, especially anthropologists, to ridicule its recognition among early Indian cultures because they are anxious that it may displace culture-oriented rituals or practices (Heth 1992).

As stated by Toelken (1991) in his work Ethnic Selection and Intensification in the Native American Powwow (as cited in Stern & Cicala 1991, 137): â€Å"Perhaps because their participants seem to be having fun instead of playin g to the white stereotype of Indian stoicism†¦ the contemporary intertribal powwow, an increasingly popular vernacular dance expression among Native Americans, has not been given much attention by scholars, even though it has become one of the most common articulations of ‘Indianness’ among Indians today.† Kiowa Song As the language of Kiowa keeps on weakening in its commonplace usage, a song is surfacing as a leading representation for expressing the identity and legacy of the Kiowa people. However, a song cannot be deprived of its storyline perspective; specifically, for numerous Kiowa singers, narrative is entirely important for interpreting songs (May & Hood 1983).
