Does stakeholder theory provide a better basis for the development of Coursework

Does stakeholder theory provide a better basis for the development of Corporate Governance in the 21st century than agency theor - Coursework Example It is important to understand the meaning of corporate governance to be able to fully discuss its features. Even though there are different variables that come into play because of the different operating environments in different nations, corporate governance may refer to that process that leads to effective control, direction and accountability in organizations. As a result, corporate governance involves elements like control, co-ordination, direction and the checks and balances associated with management of organizations. In addition to the definition of the term corporate governance, it is equally important to point out that the practice has evolved over the years to become a more complex but essential feature for the success of contemporary organizations. The concept of corporate governance has been fast adopted in various parts of the world but with some major variations because of the different circumstantial variations of nations (Clarke 2004). Consequently, there have been d ifferent frameworks of corporate governance that have emerged as a result of this. However, there are two main approaches of corporate governance that can be identified. ... at had a tradition of common law like Australia, United Kingdom, USA, Canada and New Zealand developed corporate governance structures that focused on shareholders’ returns or interests. In their case, corporate governance was supposed to ensure that corporations achieved the objectives set by their owners. Consequently, the two main corporate governance approaches have been termed as insider and outsider approaches respectively. Having reviewed the background of corporate governance it is therefore important that the theories of corporate governance that have been put forth be discussed. Theories of Corporate Governance There are two theories of corporate governance that have been proposed by scholars and of which will form a basis for this discussion. They include the stakeholder theory and the agency theory as discussed below. The Stakeholder Theory Also referred to as the stewardship theory, the theory proposed by Freeman is based on the argument that organizations have a wider obligation of serving the general interests rather than just attaining the capitalistic goal of wealth maximization (Mulili and Wong 2011). The theory holds that firms are socially responsible to all parties that interact with it or those that are affected by the firms’ quest on achieving its set objectives (Freeman et al 2010). As a result, corporate are said to be socially responsible to their stakeholders, that is, the suppliers, employees, clients, shareholders, interest groups and the government among other industry actors they are directly or indirectly involved with. It has been noted that stakeholders are important to corporations because the manner in which they are handled determines their feedback (Gregg 2001). For instance, when they get more in terms of value or extra

Nanotechnology Applications in Medicine - Essay Example Atiyeh states â€Å"silver is a viable treatment option for burns and open wounds† (Atiyeh 139). The technology of nano medicines has blessed the human mankind with some exhilarating aptitudes and possibilities. Nanomedicines have made it possible to transform various techniques that were previously in the stage of imagination and testing to their actual usage in the present era. The technology involving utilization of nanoparticles in medication is at present under augmentation. However, long term prospects of research in this field suggest that the nano-robots can be used to make adjustments at cellular level in the human body. The advantages of nanotechnology in the discipline of medicine could refashion the fate of medicine by apprehending and medicating the human body in any kind of ailments related to various diseases. The bright future of nanotechnology also advocates that those techniques that were imagined a few years before are now making fortunate progress towards r ealism. Application of Nanomedicine in Drug Delivery One remarkable appositeness of nanotechnology in the field of medicine is the employment of nanoparticles to convey medicines, heat, light and various other type of materials to the disease causing cells for example cancer cells. These nanoparticles are manipulated in a way that they are lured towards diseased cells and then directly treat these cells. By this technique injuries to the healthy cells are reduced and disease is encountered much earlier as compared to other techniques. Nanoparticles that are involved in the allocation of chemotherapy drugs to the cancer cells are under the process of advancement. The consummation of Phase 1 Clinical Trial of the directly targeted chemotherapy annihilator drugs are communicated by some organizations like CytImmune and BIND Biosciences (Torchilin, 282). Although the tests are in progress but their approval for the ultimately final administration on cancer sufferers is still imminent. T he utilization of heat along with chemotherapy medicines to the cancerous cell is another alternate form of nanomedicine that is used to treat cancer patients. The remarkable technique involves usage of gold nanorods to which DNA strands are adhered. These DNA fibers serve as platform and grasp collectively together the gold nanorod along with the chemotherapy medicines. When the cancerous cells are irradiated with infrared light, these rods suck up the infrared light and convert it into heat energy. The warm temperature helps to liberate the drug and obliterate the cancer cells. Research is also being executed to develop a nanoparticle that is able to skirmish viruses. The nanoparticle does not itself consist of the ability to devastate viruses but it clement an enzyme that diable the reproductive mechanism of viruses in the patient’s body. Another investigation is being done on nanoparticles that can treat neurological disorders by releasing medicines through the brain barr ier. Increasing immune reactions by combining the vaccine particles to DNA nanoparticles is another practice on which explorations are going on. These special vaccine molecules mark the white blood cells directly and enhance their immune response many folds. Nanomedicine Application in Therapy Techniques The nanoparticles made up of polyethylene glycol-hydrophilic carbon clusters (PEG-HCC) have the ability to absorb free radicals at an elevated speed than the original free radicals

Study and Overview of Multinational Banking

Study and Overview of Multinational Banking Introduction: Banks have always been a topic of great discussion as well as great importance. The Banks have been an integral part of the whole economy of the country and hence add greater value to its existence. However, the past suggests that the banks have broken their domestic shackles and entered different markets in foreign countries. Global banking has then emerged as one the most important and biggest industry in the world. This was primarily because of the assessments made by bank management on the growth and profits associated with globalization. In the current scenario, almost every bank internationalizes its operation sooner or later and hence makes it even more important to understand the associated concepts in globalization policy. The research is to propose a well scrutinized description of its determinants and risks associated with it. A further emphasis is given in regards to the risks of multinational banking as the past decades have experienced a lot of banking crises which many regard as an adverse effect created by diversification of banks. Studies in the past have more been on the FDI made by Multinational corporations in trade industry however less has been written about FDI in banking industry even though they have been neck and neck with the other industries in terms of globalization with banks such as HSBC, ICICI, JP Morgan, Citibank, Royal Bank of Scotland and Barclays heading the way. The massive banking industry makes it very difficult to conduct a complete study of all its aspects and hence the key aspects of its globalization have been considered and researched. The involvement of the author in a research related to the study of multinational banking is caused because of the following reasons: Firstly, banking industry has been a key sector in the economy of any country and the success of a country has at times also depended on the functioning of its banks. Secondly, the author has immense interest in the banking field and has always been fascinated by the activities and operations of banks across the globe. Lastly, the personal interests of the author in the globalization field as how and when have firms entered foreign markets. Hence, the investigation of cross country banking industry has made the study very appealing The primary objective of this study is to investigate and highlight the determinants for the growth of multinational banks and to develop an integrated approach to explain the phenomenon of multi nationalization of the banking industry. Also, to intricate the risk associated with multi nationalizing of banking operations. The primary consideration underlying the study is the fact that most of the research and resulting hypothesis are confined to manufacturing and extractive industries. Indeed, lack of empirical studies on multinational banking was also highlighted by Aliber (1984) in the only survey of the literature on this subject. The following are the specific questions that have been dealt and explained in the research study: What are the key determinants behind a bank opting for globalization of its activities? Why do some banks and not others adopt this policy? Why is foreign rather than domestic operation advantageous in serving foreign markets? What are the risks associated with globalizing of banking activities? What are the key considerations in terms of which host country to invest and globalize activities in? The research strategy, design and methodology provide the reader with an in depth view into the framework of the research process undertaken for this study. A separate section has been created called Research Methodology which analyses all the various techniques used in the research such as a research design, difference between the various types of research and the ethod adopted. Also, it highlights the sample used for conducting the primary research and also the research method adopted to collect the primary data. The primary data to brief it up has been collected through a qualitative in depth interview covering a sample of five management level interviewees from banks of UK as well . This chapter starts of with the significance of the commencement of the study highlighting the key reasons behind the selection of the topic and includes a background to the study as well as the personal interests of the researcher which further motivated the specific research. Also, the chapter lays down the aims and objectives of the research with a brief introduction to all chapters included in the study. This chapter has been further divided into two chapters. Chapter 2A stresses on the multinational banking industry as a whole and lays down the definitions and the key characteristics of international banking. Also, it highlights the various entry method options available to a bank in entering specific foreign markets. Chapter 2B then emphasizes on the growth of this industry and reasons behind its outburst. Determinants and risks associated with global banking are discussed in the next section. The chapter ends with a schematic conceptual model developed by the researcher to diagrammatically explain the multinational banking phenomenon. This chapter has been prepared to give insight to the way the whole research has been conducted. The chapter starts of with a strategy of adopting the form of research design and then follows a pattern of discussing, differentiating and selecting among the various options available in conducting the research such as qualitative or quantitative, primary or secondary, questionnaire or interview. The chapter then lays down the difficulties faced by the researcher in his research. Before this chapter, the research has been primarily been related to collecting secondary data from literature resources and primary data from the sample selected for the survey. However, this chapter deals with the analysis and interpretations of the collected data. Hence, the chapter becomes even more important for the correct interpretation of all the data collected. This chapter has been divided into several sections putting light into all aspects discussed in the research method. Also, this chapter explains the information collected from the survey which is then compared and contradicted with the literature. This chapter then explains the conceptual model shown in the literature review chapter. The chapter summarizes the whole research process by laying down the key findings. It further highlights the answers suggested in the study for the aims and objectives laid in the introduction. The chapter further suggests how this study could be used in the banking field and how this research could be enhanced by the future researchers. To conclude the researcher expresses few recommendations to the management in the way the globalization of banking is conducted in the modern era. The key contents of the study have been laid down in this chapter to give an idea of what the study has been conducted for. The aims and objectives of the research have been briefly explained. Also, the research has been more of a personal interest as the study topic has been captivating for the researcher. The second chapter now focuses on the literature in the field of global banking highlighting the key findings and views made by the early researchers. LITERATURE REVIEW: Introduction to Multinational Banking This chapter explores critically the literature that has surrounded multinational banking for the past few decades. The literature has been divided into 2 parts. The first part (A) explores the multinational industry as a whole with a detailed explanation of its key characteristics and the modes of entry a bank can apply for it globalization. Whereas, part (B) highlights the background and the growth of multinational banking as a major industry in the world business followed by a scrutiny of its key determinations and risks. Concept of Multinational Banking This chapter emphasizes on the concept Multinational Banking and the various aspects related with it. The chapter is divided into four sections to make it simple and clear. The chapter begins with the basic meaning and definition of a multinational bank and the types of multinational banks. The second Section then highlights the key characteristics of MNB. The modes of entries for a MNB are then discussed illustrating the various ways in which a bank can internationalize. The chapter finishes with the concluding comments in fifth section. Definition of a Multinational Bank (MNB) Multinational banking involves the ownership of banking facilities in one country by the citizens of another [Baker and Bradford (1974), Baum (1974), Lees (1974 and 1976) and Robinson (1972)]. The definition of a MNB is subject to an array of interpretations and is also used interchangeably with terms such as International Bank or Transnational Bank. Broadly, a multinational bank can be classified as an institution through correspondent relationship, foreign direct investment or direct lending to customers from home offices that engages into cross country banking. In many instances, however, multinational bank is used to refer to a bank with physical presence outside its home country through a branch, an agency, a wholly or a majority owned subsidiary, or a bank formed by merger of two or more banks based in different countries and not the ones with a correspondent relationship or a representative office. Robinson (1972) defined Multinational banking as operating a bank in, and condu cting banking operations that derive from, many different countries and national systems. A multinational bank can be compared to a multinational company and can be classified as a financial multinational corporation as they enjoy similar advantages and disadvantages in host country. However, this theory can only be applied to commercial bank that engages in local banking activities in the host country and hence competes with the native banks. Whereas, a Multinational corporation can little be compared with the bank that operates in the super national markets such as Euromarkets as they do not compete with the local indigenous banks. (M.K Levis 1987). H. G Grubel (1977) was one of the first authors who offered a general theory to explain the existence of multinational banking. He argued that MNB had three different types, which needed different explanations. The first was the multinational retail banking, which entered foreign markets to serve local customers through the same local deposits and loans facilities as domestic banks in the host countries. The second category was the multinational service banking, which consisted of banks servicing the requirements of corporate clients and expatriates from its home economy in foreign markets. Lastly, the multinational wholesale banking, it involves taking large deposits, and the making of large loans and investment. It is worth mentioning that Hoschkaà ¢Ã¢â€š ¬Ã¢â€ž ¢s (1993) similar definition of a multinational financial services corporation (MFSC) is confined to firms that provide banking services. In his view the fact of possession of a representative office in a given country doe s not imply that the owner of this office may be called an MFSC, as it merely serve a liaison function for a parent firm but cannot actively operate in the host market. However, the definition the researcher has used for the multinational bank is of any bank which internationalizes it operation. (Jones. G) After we have discussed the related literature on multinational banking in the chapter two, this chapter discusses in depth the research strategy, design process and the methodology used for investigation. It provides the reader with an insight into the various methods and techniques used for this study. The main discussed issues are based on the proposed stages of the research process by Antonio as shown in the table below: Problem Discovery and Definition Research design Sampling Data collection Data processing and analysis Conclusion The stages of the research process Antonio Exploring Marketing Research, USA: The Dryden Press Problem discovery and definition The formulation of the problem is often more essential than the solution. Albert Einstein. According to Malhotra and Birks (2003), problem definition can be defined as the the general problem and the identification of the specific components of the marketing research problem. Problem discovery and definition is regarded as the primary method in any research and also one of the most important. Therefore, it is very important to understand the nature, scope and limitations of the problem in order to avoid any misinterpretation and to make it understandable to marketing decision makers and marketing researchers.

Use of Biblical Imagery in Margaret Laurences The Stone Angel :: Stone Angel Essays

Use of Biblical Imagery in Margaret Laurence's The Stone Angel In the novel The Stone Angel, Margaret Laurence introduces a character who seems to evolve her life around biblical imagery. Hagar Shipley, a ninety year-old woman, does not accept things easily, like life. Hagar is recognized as a biblical imagery because of her name. "Hagar" is introduced and recognized in the Old Testament as the Egyptian hand-maiden of Sarah, the wife of Abraham. By reason Sarah was unable to provide offsprings for Abraham. Since Sarah could not concieve, she gave her servant, Hagar, to her husband, so she can produce heir under Abraham's name. And Sarah said unto Abraham, Behold now, the Lord that restained me from bearing: I pray thee, go in unto my maid; it may be that i may obtain children by her. And Abraham hearkened unto the voice of Sarah... And he went in unto Hagar, and she conceieved, her mistress was aespised in her eyes". (Genesis 16, 2-4) Symbolically, Hargar Shipley became a house keeper in her younger years. Hagar has always felt that she was to take care, nurture, serve others, it bacame her natural positon. Hagar saw herself as the "chatelaine," or possibly an outcast when she was married to Bram. The Shipley house was square and frame, two-storied, the furniture shoddy and second-hand, the kitchen reeking and stale, for no one had scoured properly there since Clara died. Yet seeing it, I wasn't troubled in the slightest, still thinking of myself as a chatelaine. I wonder who I imagined would do the work? I thought of Polacks and Galicians from the mountains, half-breeds from the river valley of the Wachawa, or the daughters and spinster aunts of the poor, forgetting that Bram's own daughters had hired out whenever they could be spared, until they married very young and gained a permanent employment." (p. 50-51) Hagar is feeling like a prisoner in her own habitat, that she is not "free" in spirit; "I was alone, never anything else, and never free, for I carried my chains wihin me, and they spread out from me and shackled all I touched" (pp. 292). The imagery that Hagar is enslaved like the prisoners in the early era's, B.C.-A.C., she became a slave of her own emotions which is strugggling within her. Also noted, Hagar also was seen and explained as "a creature of wilderness". Like the pharaoh's daugheter, she left the security of her father and went to explore the wilderness.

History of Minnesota Multiphasic Personality Inventory Essay

The assignment was to select a significant event in the development of psychological testing, such as the Chinese use of essay exams for civil service selection, the use of alpha and beta testing in World War I, Wundt’s laboratory, or the development of the Minnesota Multiphasic Personality Inventory (MMPI). This paper will discuss the Minnesota Multiphasic Personality Inventory (MMPI); explain its significance and how it has affected the development of psychological testing in the 21st century. Significance The Minnesota Multiphasic Personality Inventory was published in 1940 and the second revised version was published in 1989 (MMPI-2). It is used to measure adult psychopathology and is the most commonly used measurement in the world (Drayton, 2009). The test was developed with a set of answers that healthy adults would answer and then provides indirect questions as to prevent individuals from being able to skew their answers to get a more favorable result. This allows clinicians to have an objective measure rather than basing a diagnosis off of their minimal assumptions. The test (MMPI-2) is a self-report measure of a person’s psychological state and includes 567 items of true/false questions. According to Drayton (2009), â€Å"It has nine validity scales (or ‘lie’ scales), assessing for lying, defensiveness, faking good and faking bad and among others. These scales make it very difficult to fake the MMPI-2 results. The measure has many clinical scales assessing mental health problems (i.e. depression, anxiety, post-traumatic stress disorder), personality characteristics (i.e. psychopathy) and general personality traits such as anger, somatization, hypochondriasis, ‘type A behavior’ addiction potential, poor ego strength and many others† (p. 135). The MMPI-2 can be used to assess major social and personal maladjustment, identify potential applicants for high-risk public safety positions as well as give the ability to support a clinician’s expert testimony. It can also assess clients in substance abuse programs and assist in selecting the most beneficial treatment methodology. With rising divorce rates, this assessment can provide valuable insight for marriage and family counseling. Lastly, this test has affected the college and career counseling sector by providing support for recommendations (Ben-Porath & Tellegen, 2008) Conclusion This paper discussed the brief history of the MMPI and the MMPI-2, what it measures and what is included in the assessment as well as the significance it has in modern culture. Included was the intended use of the assessment, the basic principles that the test contains as well as the vast modern use of the MMPI-2.

Architecture Essays – Baroque Architecture Characteristics

Baroque Architecture CharacteristicsIntroductionThe Baroque period took the humanist Roman position of Renaissance architecture and showed it in a new rhetorical, theatrical and sculptural manner they expressed the victory of absolutist church and province. The chief position of Baroque architecture was more concerned about colour, visible radiation and shadiness, sculptural values and strength which could be seen in its features. Baroque is defined periods in literature every bit good as music ; nevertheless critics perceived it to be unstructured, over ornamented, theatrical and grotesque. Although many things influenced the Baroque period it was besides influenced by faith every bit good as the states political relations. Architects were interested in the infinite of the unfolding existence every bit good as the workings of the head and attempted to portray passions of the psyche through facial looks.FeaturesThe characteristics of the Baroque epoch showed long, narrow naves that w ere replaced by a broader, or on occasion with round signifiers. It displayed dramatic usage of visible radiation that could be either strong light-and-shade contrast ( known aschiaroscuro) effects ; or they used unvarying lighting by agencies of several Windowss. Another characteristic was deluxe usage of decorations ( puttos made of wood ( frequently gilded ) , plaster or stucco, marble or fake coating ) , they used large-scale ceiling frescoes and Baroques external facade is frequently characterized by a dramatic cardinal projection, nevertheless the inside is frequently no more than a shell for picture and sculpture which was seen in the late Baroque period. Baroque features besides include illusive effects like trompe l'oeil and the blending of picture and architecture and in other states such as Bavaria, Czech, Polish, and Ukrainian the Baroque manner contained, pear domes that were are omnipresent.FeaturesThe chief features for the Baroque epoch were energy, great sums of ten seness and a sense of motion from the edifices. Its picture, sculpture and architecture evolved from idiosyncrasy and broke off from the regulations of modern-day architecture, they demanded freedom to program, design and adorn their edifices with what they wanted. Columns had twisted shafts which were placed in forepart of pilasters surrounded by valances and covered with curving and broken pediments. They contained â€Å"over the top† and frequently unsuitable inside informations with carven ornament. Insides had gilded sculptures frequently in awkward airss ; the architecture was noted for its curving lines. Many of Baroques add-ons were finished in bronze, marble, gold and Ag. Baroque had a dynamic expression and experience to its design ; it was a utile categorization for insulating the inclinations and merchandises of stylistic alteration. It was seen as broad, superb, theatrical, passionate, animal, enraptured, deluxe, excessive, various and ace. It was an age of enlar gement following on an age of find, its enlargement led to still farther find about architectural design and ornament. Section A: Insides S.Maria Della Salute ( 1631-1682 ) The inside of S.Maria Della Salute is a really good illustration of Baroque Architecture and design. It displays the Baroque kernel in a manner but is non wholly over ornamented nor does it incorporate any unsuitable inside informations. Marble is chiefly used in the columns and the base appears to be gilded in bronze. Sculptures are carved from marble and stand high in the unit of ammunition of the dome. An communion table can be seen and one might presume it is besides gilded in bronze. It is an graphics in a manner but it is non â€Å"over the top† in any manner which can be seen from this position point. S.Pietro ( 1656 – 1667 ) The S.Pietro is another great illustration of Baroque architecture and design. In this exposure we can see the bronze communion table that stands merely in forepart of the apsis, we can see pictures that are decorated with gold lodgers, marble columns and high walls, the domes contain gilded ceilings. Walls are decorated with sculptures in free standing places in the walls besides made of marble. Light is given through high standing Windowss and the chief dome from above through a sky visible radiation. Versailles ( 1660 – 1685 ) The Palace of Versailles is the most good known piece of Baroque Architecture and design known to day of the month. It defines what the Baroque period was approximately. It was excessive, animal, dynamic, passionate ( pictures ) , various and deluxe. Decorations were non silver but pure gold. Soft cloths, bright colorss and beautiful sculptures decorated the insides of the Palace. In the Hall of Mirrors as seen in figure 8 sculptures themselves were cast in gold high Windowss offered light and glass pendants hung from a ceiling decorated in picture and gilded gold lodgers. In the Queens Chambers as seen in figure 7 one can state that non even the sleeping rooms were unbroken simple. Gold was besides used and to an extent it was excessively used. The focal point of 1s oculus is led to the gold ornament and non the architectural values of the edifice. The outside as seen in figure 6 one can see that the balcony railings were gilded in gilded ornament as the Sun makes this easy to see. Marble is besides used on the facade of the edifice but it is chiefly decorated in gold. Rich vivacious colorss can be seen throughout the castle as seen in figure 7 of the Queens Chambers. Section B: Interior Design Although the Baroque epoch contributed to the great edifices we see today, one can non bury about the insides. Although extravagantly decorated the insides are really good designed to suit certain facets. Architects need to believe like that in order to obtain a good sense of what works and what does non. I believe interior design does really suggest about it along the lines. We design what we think the client would wish and so acquire an thought if the client likes it of non, if non we merely do a few alterations to acquire a better feel and a better position of what they want. It is the same now as it is so. Interior interior decorators design the infinite in which the client will be in every twenty-four hours. It requires a great trade of penetration and a cognition about a individual, one might see reading your client by speaking to them, when you do that you can acquire better thoughts. Simple designs frequently make better designs in these yearss nevertheless in the past if it was large, broad and contained munificent ornaments it was classified as good.DecisionSo from looking at the Baroque architecture one can state that it played a great function in the design of edifices today. Many people who obtain an over and above wage sometimes have one or two suites that give recollection to the Baroque manner. It was surely munificent, dynamic and â€Å"over the top† ornaments were decidedly a spot much for today’s modern society.BibliographyTansey, R.G & A ; Kleiner, F.S. 1954.

Spelling Reform and the Writer

Spelling Reform and the Writer Spelling Reform and the Writer Spelling Reform and the Writer By Maeve Maddox A reader, responding to Case of the Missing is: foliage, verbiage, miniature , asks reasonably: Can’t we change the spelling? Before the widespread use of dictionaries, the answer to this question would have been Of course we can! Not anymore. The free and easy use of personal spellings to convey the pronunciation of the word intended by the person writing has not been an option since the middle of the seventeenth centuryat least not for writers who wish to avoid having their credibility questioned. Attempts to regularize English spelling began as long ago as the 1550s and reform groups are still at it. Some of the suggestions would require quite a learning curve. Reformer Thomas Smith (1568) increased the alphabet to 34 letters and put marks over all the long vowels. John Hart (1570) added special characters for sounds that dont have letters in the English alphabet, such as /ch/ and /sh/. William Bullokar (1580) created a system that made use of extra letters, accents, apostrophes, and various hooks above and below letters. Printer Ben Franklin promoted spelling reform by having a special font cut with extra symbols, and efforts have been made in more recent times to change spelling to conform to pronunciation. In 1898 the National Education Association adopted 12 simplified spellings in its publications: tho, altho, thoro, thorofare, thru, thruout, program, catalog, prolog, decalog, demagog, and pedagog. A glance at the NEAs website suggests that theyve given up on all but two. In the 1940s the Bible and some classics were printed using a phonetic system of spelling invented in the 1830s by Isaac Pitman (the shorthand man). Traditional English spelling is like our relatives: to be complained about, but not easily dispensed with. This extract from an experiment by Noah Webster (quickly abandoned, by the way) illustrates how ugly and internally inconsistent a reformed system can be: There iz no alternativ. Every possible reezon that could ever be offered for altering the spelling of wurds, stil exists in full force; On the whole, English speakers remain indifferent to the efforts of spelling reformers, and that is a good thing for writers. Writers, of all people, need to appreciate and cherish the variety of English spelling. Take this example from Robert Sklars Movie-Made America: Once admitted to the intimacies of reel life, movie patrons wanted their fantasies continued unbroken into real life. Sklar could not have written that sentence with its play on reel and real if English had only one spelling for the long E sound.

Not All Iron Is Magnetic (Magnetic Elements)

Not All Iron Is Magnetic (Magnetic Elements) Heres an element factoid for you: Not all iron is magnetic. The a allotrope is magnetic, yet when the temperature increases so that the a form changes to the b form, the magnetism disappears even though the lattice doesnt change. Key Takeaways: Not All Iron Is Magnetic Most people think of iron as a magnetic material. Iron is ferromagnetic (attracted to magnets), but only within a certain temperature range and other specific conditions.Iron is magnetic in its ÃŽ ± form. The ÃŽ ± form occurs below a special temperature called the Curie point, which is 770  Ã‚ °C. Iron is paramagnetic above this temperature and only weakly attracted to a magnetic field.Magnetic materials consist of atoms with partially-filled electron shells. So, most magnetic materials are metals. Other magnetic elements include nickel and cobalt.Nonmagnetic (diamagnetic) metals include copper, gold, and silver. Why Iron Is Magnetic (Sometimes) Ferromagnetism is the mechanism by which materials are attracted to magnets and form permanent magnets. The word actually means iron-magnetism because that is the most familiar example of the phenomenon and the one scientists first studied. Ferromagnetism is a quantum mechanical property of a material. It depends on its microstructure and crystalline state, which can be affected by temperature and composition. The quantum mechanical property is determined by the behavior of electrons. Specifically, a substance needs a magnetic dipole moment in order to be a magnet, which comes from atoms with partially-filled electron shells. Atoms will filled electron shells are not magnetic because they have a net dipole moment of zero. Iron and other transition metals have partially-filled electrons shells, so some of these elements and their compounds are magnetic. In atoms of magnetic elements nearly all of the dipoles align below a special temperature called the Curie point. For iron, the Curie point occurs at 770  Ã‚ °C. Below this temperature, iron is ferromagnetic (strongly attracted to a magnet), but above it the iron changes its crystalline structure and become paramagnetic (only weakly attacted to a magnet). Other Magnetic Elements Iron isnt the only element that displays magnetism. Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. ÃŽ ±-iron, cobalt, and nickel are ferromagnetic, while ÃŽ ³-iron, manganese, and chromium are antiferromagnetic. Lithium gas is magnetic when cooled below 1 kelvin. Under certain condition, manganese, the actinides (e.g., plutonium and neptunium), and ruthenium are ferromagnetic. While magnetism most often occurs in metals, it also occurs rarely in nonmetals. Liquid oxygen, for example, may be trapped between the poles of a magnet! Oxygen has unpaired electrons, allowing it to react to a magnet. Boron is another nonmetal that displays paramagnetic attraction greater than its diamagnetic repulsion. Magnetic and Nonmagnetic Steel Steel is an iron-based alloy. Most forms of steel, including stainless steel, are magnetic. There are two broad types of stainless steels which display different crystal lattice structures from one another. Ferritic stainless steels are iron-chromium alloys that are ferromagnetic at room temperature. While normally unmagnetized, ferritic steel become magnetized in the presence of a magnetic field and remain magnetized for some time after the magnet is removed. The metal atoms in ferritic stainless steel are arranged in a body-centered (bcc) lattic. Austenitic stainless steels tend to be nonmagnetic. These steels contain atoms arranged in a face-centered cubic (fcc) lattice. The most popular type of stainless steel, Type 304, contains iron, chromium, and nickel (each magnetic on its own). Yet, atoms in this alloy usually have the fcc lattice structure, resulting in a nonmagnetic alloy. Type 304 does become partly ferromagnetic if the steel is bent at room temperature. Metals That Arent Magnetic While some metals are magnetic, most are not. Key examples include copper, gold, silver, lead, aluminum, tin, titanium, zinc, and bismuth. These elements and their alloys are diamagnetic. Nonmagnetic alloys include brass and bronze. These metals weakly repel magnets, but not usually enough that the effect is noticeable. Carbon is a strongly diamagnetic nonmetal. In fact, some types of graphite repel magnets strongly enough to levitate a strong magnet. Source Devine, Thomas. Why dont magnets work on some stainless steels? Scientific American.

Opening Premier Inn hotel in Mauritius Essay Example | Topics and Well Written Essays - 2000 words

Opening Premier Inn hotel in Mauritius - Essay Example There is also the strategy of wholly owned subsidiaries a form of foreign direct investment that includes acquisitions and the Greenfield investment. The Greenfield investment is preferable if there are no competitors in Mauritius and it is a high-risk strategy. In addition, the hotel can consider acquisitions since it is a technique that can help to actualize higher human potential. It also contributes to lower risk than most of the entry models (Hill, 2014). The best design for the hotel is Foreign Direct Investment by procuring land, plant, and workforce in the host country. The hotel can set up a subsidiary that is wholly owned in the country by establishing a branch from the ground. In doing so, the hotel will be using the Greenfield strategy; on the other hand, it can also acquire a plant in the target foreign market (Hill, 2014). The hotel will experience significant benefits in the acquisitions. Firstly, purchases are quick to execute. The hotel should acquire an already established enterprise in Mauritius, by doing so it can quickly build its presence in a foreign target market. Therefore, the Premier inn hotel should do the same (Razin and Sadika, 2007). Secondly, the hotel should make acquisitions as a tool to pre-empt competitors since in Mauritius there are many investors in the hotel industry. The need for the pre-emption is especially prominent in markets that are rapidly globalizing. Thirdly, managers of the Premier inn hotel may view acquisitions as less risky than a Greenfield venture. Practically when the hotel purchases another hotel in Mauritius, it buys a number of assets that generate a known profit stream and revenue. On the contrary, the profit stream and income produced by a Greenfield venture is indeed uncertain simply because it does not yet exist. Acquisition made at the Premier Inn hotel in Mauritius; it does not only acquire a number of tangible assets. For example, it will

Schmid compliance Essay Example | Topics and Well Written Essays - 500 words

Schmid compliance - Essay Example This is a dicey issue. On one hand, the school, since it must make budget cuts, is being forced to eliminate the women’s varsity softball team. Also, one of the mens’ teams is being cut as well, so it would appear that the university is not being unfair in any manner. However, since the school is approximately 50% men and 50% women, and since 39% of women compete in sports, it seems as though the school may have a difficult time making their case for why this program should be cut. On one hand, the womens’ softball team does have less athletes, than say, the womens’ swim team. It would therefore seem like a logical choice that, in the face of budget cuts, the womens’ softball team would be the first to go. However, considering the fact that the school is comprised of about almost the same amount of men, it seems that the university would want to comply with Title IX. The female student athletes could probably make a reasonable argument that they wer e not being given reasonable accommodation under Title IX. These are the facts. 3. On which of OCR’s three â€Å"benchmarks† for measuring effective accommodation of student athletes’ interests and abilities might the college base its defense? What arguments could the college raise under each? The first benchmark is one that the college might base its defense on. The college could raise the factors under each benchmark that: a) the college had to make budget cuts; b) the cuts that were made were made both to the mens’ and womens’ teams;

Audit Essay Example | Topics and Well Written Essays - 2250 words - 2

Audit - Essay Example Auditing procedure is also applicable in case of stock and inventory management because this is also an area where high chances of corruption take place. Many organization has own internal audit department by which the company can control and monitor business activities after certain period or as and when necessary. External auditors will generally visit any company once in a year to provide more biased free judgment about the financial position of the company. Independent reports are required by auditor to increase the faith of stake holders on the company’s activities and attract more amount of capital for the purpose of business. For the above mentioned reasons rotation of auditors are also important which is recognized as precaution to save the interests of all the parties who are related in the business activities. Auditor rotation also can be said as independence of auditor and this method can be applied on both internal and external auditors. At the time of conducting audit of any particular company day after day or year after year then he will get information about all the strategies the company has taken or will going to take. They can make friendly relationship with the management and employees of the organization which will affect to provide unbiased opinion about the current condition of the company (Loughran, 2010). So this is clear that auditor rotation is required for the independent opinion of auditors. There are generally 3 types auditor can be observed. These are external audit, internal audit and audit committee. In case of internal auditor independence means bias free opinion from those parties whose interests may be affected by the audit operation or the disclosure of auditor’s report (Clayman, Fridson and Troughton, 2012). Poor governance, inadequate risk management, inadequate internal control etc. are few reasons where

The Ocean in Crisis Research Paper Example | Topics and Well Written Essays - 2250 words

The Ocean in Crisis - Research Paper Example In some places like arid desert where fresh water is not readily available, ocean water serves as a lifeline for societies who can decrease its salt content to a safe level. Humanity’s dependence on the oceans is not a recent development, but has existed for thousands of years, ever since man first realized that he could master the resources that the ocean has to offer. Humans are not beyond that basic dependence on regulation and equilibrium in how they interact with the vast oceans of earth. Unfortunately, much of this equilibrium between the health of oceans and the health of civilizations has disappeared in the last century, with the rise of grave threats to the world’s seas. Problems such as acidification, climate change, pollution, and overfishing have resulted in the need for civilizations to rethink how they exploit the oceans to support necessary institutions. Of course, the existence of these threats is not always clear, so the purpose of this paper is to eluc idate some of the inevitable dangers humans pose to the oceans and how those dangers can be reversed. Acidification Acidification is a process of decreasing the pH level of some substance—in this case, earth’s oceans. The process of acidification is occurring at a faster rate because of higher levels of carbon dioxide in the atmosphere. Because levels of carbon dioxide in the earth’s atmosphere remain relatively stable, the excess carbon dioxide is taken up by the oceans (Raven and Falkowski). Dissolved carbon dioxide produces acids such as carbonic acid and bicarbonate. A lower pH has the effect of making ocean waters more acidic, which means most importantly that oceanic calcifying organisms such as corals, crustaceans, echinoderms, mollusks, foraminifera, and others will be vulnerable to the negative effects of a more acidic ocean. Fundamental disruptions to the ecosystems of these organisms that lie at the bottom of the ocean’s food chain will have pr ofound, and most likely irreversible, influences life in the ocean (Nienhuis, Palmer and Harley 10). Keith Sherwood and Craig Idso argue against those who claim ocean acidification poses a significant problem to earth’s largest ecosystem based on a review by Hendriks et al., published in 2010. According to the report, warnings that ocean acidification poses a significant long-term threat to marine biodiversity are based on theoretical models that do not account for numerous biological phenomena and are not supported by empirical observation. According to Sherwood and Idso, biological processes are capable of homeostasis against significant changes in pH levels within the range predicted during the 21st century. However, the essential contradiction here is that the conclusion being offered by Sherwood and Idso is based on the same theoretical models that they claim are not supported by empirical observation earlier; that is, â€Å"the range predicted during the 21st centuryâ €  is a prediction based on a theoretical model of how acid levels in the bulk waters of the oceans will change. A major problem Sherwood and Idso do not address is whether predictions about acid level increases are actually reliable when by their own admission, Sherwood and Idso do not think so. Perhaps acid levels will rise much more than predicted, which would call into the question their conclusion that homeostasis can make up the difference. Climate Change Climate change and ocean acidificati

Fred Jones Constructon Essay Example | Topics and Well Written Essays - 2500 words

Fred Jones Constructon - Essay Example Insofar as the products are concerned, there is also a need to define the branding strategy thast can compete against other brands in the market. And in order to be competitive, there should be some awareness of the competitors’ strategies against which the Fred Jones Construction strategies for storm roof repairs will strive to be more captivating to potential customers. I.Industry & Market Analysis The storm roofing business realized a boom in Dallas right after a tornado touched down in April 2-3.2012 and a year ago in April 27, 2011. $ 100 million worth of insurance claims had been reported in 2011 for Dallas alone, based on the news report of Nielsen and Richter (2012). There were 19 separate warnings about a tornado approaching Dallas population with 6.3 million people. Hail brought by the powerful wind could be as small as peas and as big as a baseball. In mid-June 2012, Dallas experienced â€Å"the massive hail storm† which was estimated to have resulted in $ 2 billion worth of insurance claims (Richter and Berkowitz 2012). And sop, even if 1,000 contractors of roof repairs are tapped to fix all roofing and housing repairs, each contractor would have a potential market of about $2 million. One of the major industry players, MyRoofDfw (2013) in the roof repair industry within Dallas Forth Worth Metroplex disclosed that there are more than 1,000 companies offering the same products and services in the location. But that company also forecasted only about 10% will remain operating within the next 10 years. That company boasts of having the expertise at roof replacement, leak repairs, insurance claims assistance, lowest pricing, free estimates, and free consultancy for home roof condition reviews. Aside from these, the company offers more than a dozen related services listed in its website. Six of those services are free because those are about inspections pertaining to different reasons for repairs. Competitors like Circle H Roofing & Constru ction have communicated to the public the problem of unpredictable weather changes that have damaged roofs due to hail, fallen trees, and strong winds. They have set the customer’s expectations (Circle H 2013) way ahead of the customer’s decision to secure the products and services from their respective companies. This is good because the homeowners can also plan ahead whatever would have to be prepared by the time the products and service crews arrive. Companies offering both products and services are transparent about schedules, how customers may pay through financing, and what repairs are to be expected. They also offer free inspections and quotation. Their products and services are all with warranty from the company that fixed the problems. Furthermore, they assist homeowners in claiming for property damages due to storms. Another competitor, Bennet Roofing (2013) gives importance to the presence and availability of its â€Å"experienced, professional staff† and the capability to â€Å"install and repair all types of residential and commercial roofing† aside from offering free inspection of roof damages. One of its strategies for storm roof repairs is the combination of educating the customers using their website about what needs to be done in order to claim for damages from insurance companies and then to mention towards the latter part that Bennet Roofing offers to perform all those long, tedious step-by-step process for

The Lottery by Shirley Jackson Essay Example for Free

The Lottery by Shirley Jackson Essay The short story, The Lottery, by Shirley Jackson is one pf the most shocking stories I have ever read. It caused controversy when it was published in a New York newspaper and for good reason. The ending is very unsettling and I would even categorize it as a horror story. The picture the story paints prepares you for the exact opposite of what actually happens, making this a confusing, yet unforgettable story. It is hard to figure out what the message is in this story. Starting from the beginning there are many things one must notice upon a second reading. Subtle symbolism is used in a genius manner so that only on a second reading can the reader understand what the author is doing in every paragraph she writes. Throughout the story we are never sure about what exactly this lottery is, which keeps the reader in suspense. The story begins with a cheerful mood. It is summertime in a small town of 300 people. Every character comes off as friendly and full of positive energy. Jackson sets the scene for a beautiful day by describing growing flowers and beautiful grass. The reader is reeled into a peaceful mood and becomes comfortable in knowing this is peaceful story. The only confusion in the beginning is when the children are gathering stones and making piles of them. The reader may indicate the children will be throwing the stones, yet in a childlike playful manner and no violent premonitions can be made due to the peaceful setting counteracting and overpowering any violent thoughts. The interaction between characters is 100% friendliness. The story informs us that everybody in town is gathering at the town square, which is located between a post office and a bank. At first this means nothing extraordinary until you realize that no other buildings are mentioned. No courts or police stations, which are usually found in a towns square, are mentioned. No mentions of authority whatsoever except for Mr. Summers, who runs the yearly lottery. It is also interesting how we are informed that he runs a Halloween program, which is known for trickery, yet no other holidays are mentioned. The mood of the story seems to take a turn when we learn about the villagers reaction to the black box that holds the lottery slips. They seem to be  nervous around the box. Once the winner was found, we notice his reaction is not a good one. Then we read on to find that the villagers will throw stones at the winner until they kill him. This is done so casually that it creates an eerie feeling as we read how the villagers surround the victim and prepare to kill him. The story ends there. The Lottery is definitely an interesting tale by Shirley Jackson. But what is she implying by this story? Surely she didnt write this ending because she felt it was cool. There is a not so obvious message we must analyze. My conclusion leads me to believe that this is a story about tradition. The villagers follow tradition without even knowing why the tradition exists. In the story, Old Man Warner states, Theres always been a lottery he said petulantly. In this statement, the reader sees the most ignorant of all excuses for doing anything. This, however, seems normal for the community. The reader then discovers That much of the ritual had been forgotten or discarded, Mr. Summers had been successful in having slips of paper substituted for the chips of wood that had been used for generations.' While reading, the reader starts to understand the lottery tradition from which many rules and regulations disappeared for convenience reasons. This leads the reader to believe that the villagers do not truly understand the origins of the lottery. Mrs. Jackson states The people had done the lottery so many times that they only half listed to the directions?' In this passage, the reader learns through the nonchalant ness of the villagers actions that an important event does not gander much attention. They kill the victim simply because its tradition. To put it simply, the author is trying to say that you shouldnt do things simply because others have done them. There may be a better way of doing things. I think she is implying that traditions found across the globe may be foolish at times and people should think logically and not do things simply because they were born doing it, like the baby who is handed stones, yet to make sense out of things, and discard those which do not make much sense. This is a strong message in todays society where tradition may cause destruction and hate amongst human beings. I could be wrong, but if I am correct, those who read should learn a powerful lesson and take a look at  their beliefs and make the right change.

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). CREATE ROW TYPE Student (      id CHAR(5),      name ROW (first VARCHAR(12), last VARCHAR(20)),      course SET (VARCHAR(128) NOT NULL)   );   CREATE TABLE students OF TYPE Student;   INSERT INTO students   VALUES (      st031,      ROW(Jane, Hunter),      SET(Economy, Planning)   );   INSERT INTO students   VALUES (      st072,      ROW(Richard, White),      SET(Computers in Engineering) ); Other SQL ORDBMS suggests other composite type constructors, for example VARRAY or ARRAY instead of the SET, and OBJECT instead of the ROW. 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.

Where data handling requirements are simple and suitable to rigid row and column structures an RDBMS might be an appropriate solutiuon. However,for many applications, todays most challenging aspect is controlling the inherent complexity of the subject matter itself the complexity must be tamed. And tamed in a way that enables continual evolution of the application as the environment and needs change. For these applications, an  OODBMS  is the best answer: COMPLEX (INTER-) RELATIONSHIPS If there are a lot of many-to-many relationships, tree structures or network (graph) structures then Versants  OODBMS  solutions will handle those relationships much faster than a relational database. COMPLEX DATA For many applications, the most challenging aspect is controlling the inherent complexity of the subject matter itself the complexity must be tamed. For these applications, a Versant  OODBMS  is the best answer. Architectures that mix technical needs such as persistence (and SQL) with the domain model are an invitation to disaster. Versants  OODBMS  solutions let you develop using objects that need only contain the domain behaviour, freeing you from persistence concerns. NO MAPPING LAYER It is difficult, time consuming, expensive in development, and expensive at run time, to map the objects into a relational database and performance can suffer. VersantsOODBMS  solutions store objects as objects yes, its as easy as 1, 2, 3. Versants object database solutions are designed to store many-to-many, tree and network relationships as named bi-directional associations without having the need for JOIN tables. Hence, Versants object database solutions save programming time, and objects can be stored and retrieved faster. Modern O/R mapping tools may simplify many mapping problems, however they dont provide seamless data distribution or the performance of Versants  OODBMS  solutions.

Friendship in The Kite Runner by Khaled Hosseini Essay examples -- Kit

Friendship in The Kite Runner by Khaled Hosseini Theme: Real Friendships are more than a stubborn act; they are actions that surround your soul in order to uncover the truth that you're seeking in a friend. Friendship, as understood here, is a distinctively personal relationship that is grounded in a concern on the part of each friend for the welfare of the other, for the other's sake, and that involves some degree of intimacy. As such, friendship is undoubtedly central to our lives, in part because the special concern we have for our friends must have a place within a broader set of concerns, including moral concerns, and in part because our friends can help shape who we are as persons. Given this centrality, important questions arise concerning the justification of friendship and, in this context, whether it is permissible to ?trade up? when someone new comes along, as well as concerning the possibility of reconciling the demands of friendship with the demands of morality in cases in which the two seem to conflict. In the novel, The Kite Runner, Khaled Hosseini explores the struggles that Amir faces that confront him on the path to manhood testing friendship. One of the highlights of their friendship is their competition in the kite fighting competitions that mark the start of winter in Kabul. Amir is a master kite fighter, and Hassan is a mysterious "kite runner? able to retrieve the fallen kites and bring them home as trophies. Amir and Hassan do wonderful things together like they are brothers, but still Amir tries to test Hassan?s loyalty all the time and still is afraid of accepting being Hassan?s true friend. ?Never Mind that we taught each other to ride a bicycle with no hands, or to bui... ...want to stay for a longer period of time with someone. But does this mean that we want to be friends with each other? Testing your friend?s loyalty in order to see how faithful they are is a fine idea, but when you get carried away it can cause negative feelings and possibly a loss of friendship. A real friend is not only a speaking mouth, but also a helping hand, and sometimes even a shoulder that you can depend on. A real friendship must be tested by a long period, sometimes for ten or more years. And of course, friendship can be promoted onto a higher level, such as love. If you both have love for each other, you will make good friendship. Amir?s ideal true friend was staring at him in the face all the time but it took a while for him to realize that Hassan was the one. Works Cited: Hosseini, Khaled. The Kite Runner.

Where is The God of Justice :: essays research papers fc

Why do thousands of God fearing Latin American Christians for instance, languish in the slums in abject poverty, while the drug cartels enjoy tequila and Cuban cigars? A few months ago there was a news report that a Missionary couple of Wycliffe Bible Translators, working the forests of Guyana had been brutally murdered. In third world countries in particular there is a marked, observable distinction between the lower, middle and upper classes. As one examines the à ¢Ã¢â€š ¬Ã…“haveà ¢Ã¢â€š ¬Ã¢â€ž ¢sà ¢Ã¢â€š ¬? and the à ¢Ã¢â€š ¬Ã…“have notà ¢Ã¢â€š ¬Ã¢â€ž ¢sà ¢Ã¢â€š ¬? from a religious perspective it often seems to be the case that those who are highly religious or shall we say those who are godly often tend to find themselves at the lower end of the economic ladder while those whose lifestyles are divergent from Biblical norms seem to be flourishing. This observation is no new phenomenon however. The Psalmist David raised series questions about it in Psalm 73, Job raises a lament about it in Job 21: 7 -25 and the prophet Habakkuk contemplates it in Habakkuk 1:13. à ¢Ã¢â€š ¬Ã…“ Habakkuk asks, how can Yahweh, whose eyes are too pure to behold evil, allow the wicked to swallow someone more righteous than he? Why do the wicked prosper?à ¢Ã¢â€š ¬? The question of the prosperity of the wicked is a question of theodicy (vindication of divine providence in view of the existence of evil). It is central to section of the Bible under review, Malachi 2:17 à ¢Ã¢â€š ¬Ã¢â‚¬Å" 3:5. According to The Expositorà ¢Ã¢â€š ¬Ã¢â€ž ¢s Bible Commentary , unlike most other prophets Malachi mentioned no dateable person or events in his brief prophecy. Clues to the origin and time of his book must therefore come from the text and its implications. It has always been placed last in the minor prophets. The Talmud regularly classes the book among the postexilic prophets. The contents of the book suggest that it was written some time after Ezra. Some of the exiles had returned, the temple had been rebuilt and the sacrificial system had been reestablished to the point that where it was being abused- a matter which Malachi addressed at length. The city of Jerusalem had returned to a substantial degree of normalcy; and the inevitable lethargy, laxity and leniency in spiritual matters had developed. It is to this declining state of affairs that the prophet addressed himself. Nothing is known of Malachi apart from his book. Even his name is questioned . Some take it to be a title rather than a proper name.

High School Experience Essay

When you start a new school or a new grade you never know what to expect, all different types of emotions are running through your head sometimes that could be stress. When I started high school, I didn’t know what to do, I was the â€Å"new† kid on the block. I had to try and be outgoing and meet new people. My freshman year my priorities were not right, the last thing on my mind were my grades, my first goal was to make friends, and make them quick I couldn’t stand the feeling of not knowing people, that’s when my grades started to drop and it was very difficult to bring them back up. People say that high school is going to be the best four years of your life and being that I’m a senior, I would have to agree. These last three years has been awesome. My personality hasn’t changed; I’m still a carefree girl, just with a little more wisdom and a lot more strength. I started off school with a horrible attitude because my parents sent me to a different school. They sent me to a school where I knew about two people, I was so angry at my parents. Read more: My high school life essay Sometimes I had the thought that maybe if I failed on purpose that would probably move me to the school of my choice, Bryan Adams High School, but that didn’t work out well, all that did was get me into trouble. High school experiences are helpful for the development from a child to a young adult. Students grow together and experience the good the bad and learn from one another. Some make new friends, some loose friends and that’s just life. The last day of my high school years is fast approaching and I can only imagine how I’ll be feeling when I step out of Skyline High School. Throughout these three years, I have felt a lot of urgency about graduating high school, just wondering how it is in the â€Å"Real World†? My parents always told me to be a kid and have fun because my time will be coming, I never really thought that through but now that I’m getting older I realize it’s much easier to be a kid you don’t have to worry about many things. The only thing I can say is that I have learned. The most important thing is that, not just that I had learned through the books, but I have learned about life and the road ahead of me. From being an inexperienced freshman to a somewhat mature junior, and now a excited senior, things have really changed for me. I will leave high school as a knowledgeable senior, knowing that there are many dangers to come upon in the real world. Really, I do not know what the world out there holds for me, all I can do is enter it with a open mind and hope for the best with a positive attitude.
