Conventional Cytogenetic Report

This report is studying about conventional cytogenetic, and we will focus on a technique called ‘karyotyping’. This repot is going to introduce about the definition, the history and the improvements of karyotyping made before, what is the process and the working principle of this technique and also how if can be applied in our daily life. Karyotyping is a test to examine chromosomes in a sample of cells, which can help identify genetic problems as the cause of a disorder or disease. The term ‘karyotyping’ is come from ‘karyotype’, which is the characteristic chromosome complement of a eukaryote species.The preparation and study of karyotypes is part of cytogenetics. In the middle and late 18th century, scientists were aware of the presence of chromosomes but had difficulty studying them because of their extremely small size. Chromosomes were first observed in plant cells by a scientist called Karl Wilhelm von Nageli in 1842, but since the sample s they took had small chromosomes. After the development of genetics in the early 20th century, when it was appreciated that the set of chromosomes, the karyotype was the carrier of the genes.Another scientist Levitsky seems to have been the first to define the karyotype as the phenotypic appearance of the somatic chromosomes, in contrast to their genic contents. It took until the middle 1950s until it became generally accepted that the karyotype of humans included only 46 chromosomes. Rather interestingly, the great apes have 48 chromosomes. Human chromosome 2 was formed by a merger of ancestral chromosomes, which reducing the number. Investigation into the human karyotype took many years to settle by two famous scientists: Hans von Winiwarter and Theophilus Shickel Painter.Hans von Winiwarter examined normal human diploid cells to try and define the number of chromosomes that humans have. In his time, guesses ranged from 16 to 36. He used the most powerful microscopes available in his day in one of the first accurate karyotyping attempts, and counted specifically between 46 and 49 chromosomes in his samples in 1912. He concluded that females had two X chromosomes and males had only one X chromosome and no Y chromosome. Theophilus Shickel Painter in 1922 was not certain whether the diploid number of humans was 46 or 48, at first favouring 46.He revised his opinion later from 46 to 48, and he correctly insisted on humans having an XX/XY system. And there are two advanced skills in karyotyping. The first one is Single-Nucleotide Polymorphism (SNP), this method is going to investigate the use of virtual karyotypes for diagnostically challenging renal epithelial tumors. First is to evaluate 25 archived renal neoplasms where sub-classification could not be rendered based on morphology and other ancillary studies. Then it will generate virtual karyotypes with the Affymetrix 10 K 2. 0 mapping array platform and identify the presence of genomic lesions across all 22 autosomes.The second one is Comparative Genomic Hybridization (CGH), it is going  to scan the entire genome for variations in DNA copy number. Total genomic DNA is isolated from test and reference cell populations, differentially labeled and hybridized to metaphase chromosomes or DNA microarrays. The relative hybridization intensity of the test and reference signals at a given location is then proportional to relative copy number of those sequences in the test and reference genomes. The increases and decreases in the intensity ratio directly indicate DNA copy-number variation in the genome of the test cells.

Characteristics of the Accounting Information Systems

An accountant plays a vital role in any business; one can even say they are one of the most influential practitioners. For instance, accountants participant in generating rules and guidelines, advising day to day business activities, and even decision making. While the IT and IS communities are used frequently in many businesses, they are not the founders of the characteristics of useful information. The key reason behind this is due to the fact that accountants are the users of IS and IT communities.As being the primary users, one can expect the characteristics, rules, and guidelines for an information system to be designed by the accountants themselves. In a broader view, â€Å"accountants can assume three roles: designer, user, and auditor† (Gelinas, Dull 27). As a designer, the accountant can offer its knowledge of various principles (accounting principles and auditing principles), and various methods and techniques (information system and system development).In designing an accounting information system (AIS), the accountant can answer various questions that relate back to the seven characteristics of useful information systems. Some questions may include: â€Å"What will be recorded and how will transactions be recorded? When will the transaction be recorded and when will they be reported? What controls will be necessary to provide valid, accurate, and complete records? How much detail will reports need? † (Gelinas, Dull 27). If accountants did not design the AIS then these questions may be left unanswered without their expertise.Accountants perform many functions in an organization such as a â€Å"clerk, controller, treasurer, tax specialist, and financial analyst† (Gelinas, Dull 27). Therefore, it is necessary for them to use the AIS to perform their duties. As a user, it is imperative for the accountant to participant in the AIS process to make sure it contains the required features. In addition, knowing how to use the AIS technolo gy would be very beneficial in working effectively and efficiently. For example, a financial analyst would need to know how to store the data and access it, and how to present the information.Finally, as an auditor, one of their main interests in the AIS is the reliability of the data. Without reliability, auditors cannot â€Å"provide an opinion on the effectiveness and efficiency on internal controls† (Brazel 38). Accountants will remain the main users and as a user, an auditor as well. With the seven characteristics in mind, could they have evolved from the past? With technology not being as easily accessible as in today’s accounting world, one can assume that information was not as relevant, reliable, timely, or accessible.In relation, modern technology is so efficient in today’s world; therefore the flow of information can be quickly exchanged at any time. For example, Internet has allowed companies to send reports across the globe at any given time. This a bility gives accountants easy access to information and timely information. Without timely information, relevant and reliable information would be impossible. However, one possible disadvantage in today’s accounting world may be the relevance of the data. With such easy access to information, it can be more difficult to narrow down that information to its essence.Having too much information can make AIS more difficult to understand and increase uncertainty. Without being able to understand the AIS, an accountant cannot verify the same information. All these characteristics come hand in hand; if one characteristic fails then other characteristics will be affected. Although today’s accounting world has greatly shifted from the past, one cannot deny that the accounting community has always had a major impact in generating the characteristics of useful information.Older accounting communities created the building blocks of the characteristics. Technology merely enhanced th e flow of information and efficiency. Accounts will remain the designer, user, and auditors of the AIS.

Assessment of the Camel Cigarette Promotion and the Impact of Medical Doctors in Advertisements by Cigarette Companies

Assessment of the Camel Cigarette Promotion and the Impact of Medical Doctors in Advertisements by Cigarette Companies â€Å"More Doctors Smoke Camels†, But Does it Matter? An Analysis of Camel Cigarette Ads The 1940’s presented a far different version of America then we live in today, smoking was not only a widely accepted pastime, but many people didn’t even consider it a bad habit. While there were a few studies that had linked smoking to bad long-term effects they were few and far between and so, the habit was much more popular at the time. In 1946 the RJ Reynolds Tobacco Company produced a pro-Camel Cigarette Ad that seemed, at first glance, to be nothing more than a typical ad but upon closer examination it became clear that the ad used elements, such as a doctor, to give consumers a subconscious sense that purchasing Camels could actually benefit them somehow – almost as if the doctor were prescribing them Camels. The ad’s aesthetics create a medium where producers have highlighted certain features of their product as â€Å"important† whilst using misleading imagery to further their agenda of selling the product. The highlight of the ad seems to be the doctor, who dominates nearly half of the advertisement; his presence creates a sense of comfort and a false allusion of benefit to purchasing Camel cigarettes. As a typical consumer would you not assume that, â€Å"if doctors think it’s ok, it’s probably ok†? The use of a doctor almost implies that, as is his job, the doctor is prescribing the Camel’s to the consumers viewing the ad. Along with the doctor the ad includes a section that describes the study conducted and it’s results. These results are simple white text on a black background, so they pop, and a pack of camel cigarettes are featured next to the textual blurb, as a means to simultaneously show the consumer what a pack of Camels looks like, and to remind the consumer they are looking at a Camel ad. Lastly, in what seems to be an effort to broaden their market, the ad includes a female who references her â€Å"T-Zone†, a makeup term that is aptly reapplied to suit the producers need to sell cigarettes, but still has ties to the doctor and how he may influence women in their purchasing of cigarettes. Overall the ad uses very basic methods to appeal to those who don’t plan on further analyzing the ad and its content. The doctor used in the Camel cigarettes ad seems to communicate a sense of comfort and lull the average consumer into a state of ease, as most people would believe that what a doctor claimed to be true was true. Visually the doctor in the ad is what one would describe as the â€Å"typical wise man†. He’s old, as notable by his old, wrinkled appearance, and his greying hair. His age would imply he’s been a doctor for a significant period of time and not a newcomer to the field, and this, would further indicate that his opinion is based on years of experience, which ads further validity to what he is saying. Comparatively, the doctor is drawn in a much more detailed manor than the other character, the woman, featured on the ad as is expected due to the fact that he is the true focal point of said ad. His wrinkles are defined and his skin has a much more natural gradient – again, adding to the overall notion that this doctor and the fact that he is an experie nced doctor, are part of marketing these cigarettes. On top of visually portraying the doctor as a wise and astute man, the text bubble that accompanies the doctor refers to doctors as, â€Å"one of the busiest men in town† and â€Å"a scientist, diplomat, and friendly sympathetic human being†, each of which carry positions of influential power towards the consumer. A scientist’s opinion might be trusted when possible effects of the cigarette are being debated, a diplomat when logistics and cigarette sales are being debated, and a sympathetic human being’s when one is simply looking for a friends advice. The ad uses the doctor as a means to create someone that the typical consumer can trust, sympathize with, and believe, in doing so they also create the ideal person or people to market their Camel cigarettes. In terms of marketing for the specific brand of cigarettes, Camels, the ad places them in a variety of eye-catching places to draw, what one would assume to be, the first glance of the consumer. One cigarette sits in the doctor’s hand, and although it isn’t marked as a Camel cigarette it is still drawn to stand off of the background. Despite the fact that the doctor is wearing a white coat, the contrast between the white cigarette and the coat is still quite high, as to further highlight the cigarette. The name â€Å"Camel† is once again mentioned in large font below the image of the doctor in the tagline, â€Å"More Doctors Smoke Camels Than Any Other Cigarette†, not only does the tagline further support the claim that doctors are being used to persuade buyers to purchase cigarettes – note the bolded â€Å"M.D.† But it also shows that the Camels, although the product being sold, are secondary to the message. After appearing several times in the text blurb at the bottom of the ad the â€Å"Camel† cigarettes again pop up in the form of an image next to the aforesaid blurb. Yet again the cigarettes – now specially marked as Camel – stand out against the white background they are set on, despite the fact that they to are white cigarettes. As a whole, the ad highlights the cigarettes, specifically camels, as something good and worthwhile that a doctor might prescribe with his thoughtful and informed opinion. In an effort to broaden their market the ad includes another â€Å"mini-ad† in the bottom right corner. The mini-ad features a woman holding a cigarette – that once again is highlighted from both her and her background – to market the cigarettes to other women. â€Å"Your T-Zone Will Tell You/T for Taste/T for Throat†¦Ã¢â‚¬  is how the ad goes about expanding its influence with the T-Zone referencing a commonly used term when amongst women who frequently use makeup. However, unlike the makeup T-Zone, the ad moves the T-Zone downward to include the mouth and the throat in an effort to associate women as a whole with smoking and not correct application of makeup. Although it may seem disconnected at first, the mini-ads reinforcement of the fact that Camel’s won’t affect your throat is something a doctor would back, furthering the notion that the doctor, although not highlighted in this sector of the ad, plays an integral role in why Camelâ€⠄¢s are the best cigarettes to smoke. This Camel cigarette ad falsely uses the pedestal many place doctors and their opinions on as a means to promote their cigarettes to a larger audience. Seeing as the ad is from 1946 it’s consequences are already known to the world we live in today, we now know that smoking causes a plethora of issues in ones later life and cigarette smoking is far from a commonly accepted pastime. In terms of the this specific Camel cigarettes ad and how it may have played a role in changing society it would seem that, due to their misperception, many people were duped not only into buying cigarettes, but specially Camel cigarettes. With this notion in mind one could also adopt the idea that those who purchased the Camel’s on the â€Å"doctors orders† may have eventually developed a mistrust in doctors due to the repercussions of smoking. The RJ Reynolds Tobacco Company’s Camel cigarette ad uses doctors, their trustworthy nature, and their position of power amongst the average consumer to market their Camel cigarettes as the best on the market. The ad, produced in the 1940’s, uses the already widely recognized pastime of smoking cigarettes, and the extensively accepted notion that people trust doctors, particularly those with experience, to market and sell their cigarettes as the best on the coattails of a doctor-like prescription.

Economics Debt Essay Example | Topics and Well Written Essays - 1000 words

Economics Debt - Essay Example Historically, one of the main challenges to government leaders is the generation, and the application of a country’s wealth and resources towards â€Å"three main duties of great importance. These are as follows: protecting the country from violence and invasion; protecting, as far as possible, every member of the society from oppression and injustice, and thirdly, erecting and maintaining public works, public institutions, which can never be for the interest of any individual or group of individuals. Financing the state was basically through revenue raised through â€Å"taxes of one kind or another (Smith 476).1 Public debt was not unheard of, but was held suspect. In the last two decades, most countries have been experiencing periods where their outlays exceed their revenues, with no balanced budget in sight. Governments faced the formidable task of managing runaway budget deficits and growing public debts, both internal (owed to nationals), and external (owed to foreigners). To cover the shortfall or deficit, governments sell public assets, levy taxes, print and/or borrow money. Government borrowings to finance deficits create â€Å"public† debts, which need to be serviced through interest payments or through refinancing. Obligations of government resulting from issuing guarantees for a public sector enterprise added to the public debt become what are known as the â€Å"federal debt (Iqbal 2)2.† Available data showed that by 2007, 124 countries had been running on borrowings and that many of these countries had breached the acceptable level of public debt -to -GDP ratio. The US debt-to-GDP ratio had risen to 60.8 % in 2007. Other countries exhibited higher debt-to- GDP ratio; Japan’s debt-to-GDP ratio reached 170%, Germany, 64.9%, and Canada, 64.2 %( Nationmaster1)3. Public debt and budget deficits had become a global phenomenon and the principles of balanced budget and surplus became part of a

PRINCIPLES OF MARKETING Coursework Example | Topics and Well Written Essays - 2750 words

PRINCIPLES OF MARKETING - Coursework Example These aspects govern greater significance in the wake of the large scale competition which has emerged after globalisation where firm are trying to expand their reach beyond geographical boundaries. Customers come with a varied range of needs and wants. Products come in different categories and for customer’s having different preferences. Hence it becomes important for firms to segregate customers so as to effectively target them and prepare customised products for target markets. This can only be achieved if a firm follows an effective segmentation, targeting and positioning strategy. Segmentation is defined as â€Å"the process of splitting customer, or potential customers in a market into different groups, or in segments† (Mc Donald & Dunbar, 2007, p.34). Segmentation helps in segregating customers into groups so that the firm can prepare customised products that cater to the needs of specific segments. Segmentation segregates customer based on different characteristics which enables firms to cater to the needs of different individuals. Segmentation can be done in different ways which may be based on demographics, geography, marketing channels or products and services. Different firms segregate their customer on different basis depending on the product offering. The success of a segmentation strategy depends upon the following factors. Firstly, the segmentation strategy should cluster the market segment into a broad set of distinct customer groups. Mathematically, a customer segment must comprise of approximately 1.25 percent of the total volume of sales . Secondly firms must also look out for segments with a manageable size so as to effectively cater to the needs of the segment. Thirdly the constituents of a particular segment must display homogeneity i.e., they should have similar needs and wants and externally heterogeneous in nature which implies that the members of different segments must have different needs and wants. Fourthly the market

The Law on Occupiers Liability Essay Example | Topics and Well Written Essays - 4500 words

The Law on Occupiers Liability - Essay Example When the girl poured the contents in the glass, it contained the decomposed remains of a snail. The girl was ill in consequence and sued the manufacturer for damage in tort. It was held the defendant was liable as he owed her duty of care to ensure that the bottle should contain objectionable matter as it did. (Jertz, 2004) We find that the occupiers' liability act provides a limited duty of care on occupiers to ensure that measures for protection of properties or other people from the risks that exist, in this law we find that there are provisions that follow this act, these provisions are: it abolishes the old distinction between licensees and invitees this category of persons include anyone to whom the occupier has expressly or implicitly allowed to enter or use his premises in this case the trespasser is not included. The act provides that an occupier of premises owes to all visitors that duty to take care in all circumstances therefore, it is necessary for the occupier to ensure that the visitor will be safe in using the premises for the purpose for which he has been permitted to be there. We also find that under the act, the occupier however has a right to restrict his liability by giving adequate warning such as about slippery floors. Here the occupier is not liable where the accident has occurred through the defective work of an independent contractor was competent and so far as he was able he had inspected the work done. (Jertz, 2004) The law on occupiers' liability to an injured trespasser is usually classified under the law of tort according to the present law. Whereby tort is defined as a civil wrong free of contracts, meaning it is an act that causes harm to a determined person whether intentionally or not. The remedies for these acts are always unliquidated damages which indicate that the court has power to fix the damages. Tort normally vary from contracts whereby we find that in contracts the duties are usually fixed by the parties under agreement themselves while in tort the duties are imposed by the law. Also we find that the law of tort is an infringement of the civil rights belonging to an individual in this case we find that the wrong doer has to compensate the injured party, according to the recent law the action is brought by the aggrieved party so that he can obtain compensation. This law constitutes of three major elements that is there must be a wrongful act or omission by the defendant this means that there must a person who is being sued for his wrongful acts. Secondly there must be a legal damage and lastly the wrongful act must be of such nature as to give rise to a legal remedy in the form of an action for the damages. There also exist some civil wrongs that are actionable even though no damage is suffered by the plaintiff. An example of such a civil wrong is the trespass on land. In recent law we find that there are many types of torts such trespass and defamation but in the real sense it represents a civil wrong whose only remedy is a common law. In the case of the law on the occupier's liability to injured trespassers we find that it

Numerical Precision Research Paper Example | Topics and Well Written Essays - 1250 words

Numerical Precision - Research Paper Example In order to be concerned with the right resulting solution, Goldberg (1991) asserts that we must consider the memory and the running time of the computer. This issue is further worsened because a lot of computer algorithms add approximations to house discrete computer. Goldberg (1991) adds that Java uses a small unit of IEEE 754 binary floating point standard to signify floating point numbers and explain the results of arithmetic operations. He says that a float is signified by 32 bits and that each mixture of possible bits signify an actual number, meaning that 232 possible real figures can be signified even though there are a lot of markedly actual numbers. IEEE standards do use the inner picture same as scientific code but in binary rather than base 10. This shelters a range from +/-1.40129846432481707e-45 to around +/-3.40282346638528860e+3 and with about 6 or 7 important decimal digits, plus or minus infinity as well as not a number. The number contains ‘s’ denoting plus or minus, 8 bits for advocate ’e’ and then 23 bits for a mantissa ’M.’ Goldberg (1991) adds that the decimal number is represented by the formula given as, (-1)s * m * 2(e-127) , Where; Sign bit ‘s’ (bit 31), Exponent field ‘e’ (bits 30 - 23) and, Mantissa ‘m’ (22 - 0). Floating-point arithmetic is the famous method of representing real figures in the contemporary computers. Faking an immeasurable, real figures with the machine figures is not a job that is forthright, negotiations that are a bit ingenious must be found amid correctness, swiftness, the ease of using it, lively range as well as application and memory. I therefore argue that floating-point arithmetic along well chosen precision, radix or any other limit is a very good negotiation for a lot of numerical implementations. Good memory performance of CPUs is mostly around the locality of the orientation and this is the same with the GPUs though with se veral significant alterations. The figure below shows a comparison of memory performance of the GPU and CPU. Buck (2005) argues that it is the role of cache that gives the difference between the performance in memory of a GPU and that of a CPU. He adds that the cache in the GPU hurries filtering of surface and therefore they need to be so big as the size of the sieve kernel for the surface sampler hat is a little it tiny and being seeded computation. On he other hand, Buck (2005) vows that the GPU cache formats are enhanced for two sizes and are not wanted. This unlike to the Pentium 4 caches that works at a great clock rate with megabytes of statistics. Moreover, he Pentium 4 cache has the ability to read as well as written memory operations unlike GPU cache for read-only surface statistics. Binary Code Decimal is an example of binary indoctrination of decimal figures where every decimal factor is denoted by a secure number of bits, it is always four to eight. The main asset of Bin ary Coded Decimal is a more perfect picture and rounding of decimal units and make it informal for human-readable picture. It with an advantage that one decimal numeral can be signified by the use of

Fredricksons various models of ethnic and racial relations Essay

Fredricksons various models of ethnic and racial relations - Essay Example Stephen Cruz from the story by Terkel is a Mexican American young man whom is brought up by his father to be a hardworking and honest man, and in the process ends up acquiring education that qualifies him to work in big corporations. Initially when he is employed, he thinks that it is because of his qualification but later on, he realizes that he and other employees for the minority groups are only employed mainly for purposes of giving the company a good image and making it money.   This evidently shows and proves the ethnic hierarchy that Fredrickson identifies as one of the ethnic and racial relations. For Stephen Cruz, who was taught and brought up by his father to work hard in whatever he does and avoid taking things that he does not deserve, is seen in the story being told to fall in the line and learn the way of doing business as the dominant and powerful group does.   The Civil Acts of 1964 is used in this story to signify the way policies and legislations are used to ass imilate minority groups. Fredrickson’s one way assimilation methods is apparently used in this story as the minorities are being accepted and employed to and by the dominant group, but they still play a subordinate role and are not allowed to fully enjoy the freedoms nor fulfill their American dream (Fredrickson, 335). As Stephen Cruz rises up through the corporate ladder slowly with his sheer hard work, he continues to discover that maybe the American dream he is working on is not meant for him.(Fredrickson, 335).... This evidently shows and proves the ethnic hierarchy that Fredrickson identifies as one of the ethnic and racial relations.

As Stephen Cruz rises up through the corporate ladder slowly with his sheer hard work, he continues to discover that maybe the American dream he is working on is not m eant for him. This is because he discovers that the dream and the relations between the minority-weak and dominant-powerful, are to the advantage of the later. This relation is described by Fredrickson as group separatism. Although the method of doing so might not be as direct as it may be perceived to be, through taking advantages of various legislations and policies to their (dominant group), can be seen as a way to separate the dominant and the minority. The dominant and powerful in America continue to get stronger and wealthy and the expense of the minority. This separates the two groups even further and no equally is presented. Lastly, another

The Importance of Transformational Leadership During a Company Crisis Research Paper

The Importance of Transformational Leadership During a Company Crisis - Research Paper Example The Importance of Transformational Leadership during a Company Crisis: The Case of Wal-Mart Background of the Study A great deal of research on leadership has been carried out as such concept has been associated with a wide range of factors including the process of decision making, leader-follower interaction, and goal establishment and accomplishment, to name a few (Steane, Hua, and Teo, 2003). The notion that the concept of leadership can make significant contribution for research and development has been widely acknowledged by academicians and organizational leaders alike. Due to the rapid changes in globalization and technological trends, there has also been an increase in the need and attempt of companies to place more efforts in retaining a strong workforce while addressing the complex demands and preferences of their customers (Nielsen, Randall, Yarker, and Brenner, 2008). Because of these concerns, organizations have identified the need to effectively implement leadership, es pecially as it has been frequently linked to favorable outcomes such as an increase in performance, effectiveness, and commitment as well as improved organizational success. Hence, effective leadership becomes a crucial necessity for any company. Innovation and creativity alone may not be sufficient enough to address both internal and external pressures while the implementation of various policies and practices do not always necessarily take effect unless effective leaders are made. Leaders must possess the values and objectives that are necessary to instigate any needed change while retaining an empowered workforce to help achieve success (Jung and Sosik, 2002). The vision that they establish and the values that they live out and demonstrate to their followers plays a relevant role when such leaders make decisions that will impact the entire organization. Majority of leadership studies have indicated that transformational leadership can be the most effective form of leadership to b ring about change in any group of individuals by positively inspiring these people to create the necessary change for their success (Conger, 1999). Leaders who take the transformational approach are generally capable of motivating their followers to embrace such changes, improve their performance, and be prepared to open up to new practices, all for the better of the organization (Avolio, Zhu, Kho, and Bhatia, 2004). Company Background and Description of the Crisis Sam Walton founded Wal-Mart Stores Inc. in 1962, with its first headquarters located in Bentonville, Arkansas. It was first known across the United States as the â€Å"largest grocery retailer† and has actually expanded to include a total of 8,500 in 15 countries, with the stores taking a different name. For instance, in the United Kingdom, the stores are known as Asda, while in Mexico, some stores are known as Walmex, while India has taken to the name Best Price (Buerkle, 1999). Among the crises plaguing Wal-Mart include a negative image with regards to how it pays its workers. According to an article published in Bloomberg Businessweek, Wal-Mart has been struggling to improve its reputation because of the low wages it has been known to

Gothic Art Essay Example for Free

Gothic Art Essay Gothic art refers to an art movement in the middle ages (Van de Bogart 70) that started in France around 1140 (the time that the ambulatory of the Church of Saint-Denis was constructed [Encarta â€Å"Gothic Art and Architecture†]) and lasted up until late 16th century throughout Europe (Encarta â€Å"Gothic Art and Architecture†). In this paper, an introduction to Gothic art, with a concentration on Gothic church architecture, shall be discussed. To effectively provide an overview of this artistic style, this paper shall tackle the following: the roots of the term, â€Å"gothic†; a discussion of the characteristics of Gothic architecture; conclusion. Explaining the Term, â€Å"Gothic† The term â€Å"gothic† was used by Giorgio Vasari (1511-1574), the Italian artist and historiographer known for this book on the famous architects, to refer to the artistic style that characterize the French churches such as the Notre Dame de Paris and the Church of Saint-Denis (Chapuis â€Å"Gothic Art†). The term came from the barbarians called Goths who were then known to lack the civility that the people â€Å"civilized† people such as the Romans ought to have. These barbarians were one of the Nordic tribes likened to that of the Vandals as despoilers (Tarnocyova 69) that brought the â€Å"civilization-filled† Roman Empire into flames (Chapuis â€Å"Gothic Art†). As such, the Goths represent a regression or at the very least a certain sort of backwardness, crudeness, and lack of refinement. In fact, the Academie dArchitecture, meeting in 1710, still described unacceptable architectural manners as â€Å"gothic† (Tarnocyova 69). Hence, the term is originally a pejorative term that intends to put down an artistic style and say that the style is at the very least barbaric and rude. The reason why Vasari charged the artistic style as â€Å"gothic† has nothing to do with the merits or demerits of the style. It also has nothing to do with the logic and ingenuity that the artistic style exhibits. Rather, Vasari, just like most people during the Renaissance, were victims of the prejudices of their period. It should be recalled that the Renaissance was characterized by despise for tradition. As such, anything that belonged to the â€Å"dark ages† cannot be considered as good and of value. It is only fairly recent that the artistic manner and beauty of the gothic period is acknowledged for all its already-perceived merits. Gothic Architecture Gothic art is widely known primarily because of Gothic architecture. In fact, as was already stated in the introduction, the beginning of the Gothic period is pegged on the time of the construction of the chevet of the Church of Saint-Denis. It was 1127 when Abbott Suger, then the Abbott of Saint-Denis who was also the confidant of French Kings like Louis VI and Louis VII (Wikipedia â€Å"Gothic Architecture†), decided to rebuild the Church of Saint-Denis. This rebuilding eventually gave way to a new art period. How was this period initiated, then? At this point, it will be worthwhile to first state the Abbot’s philosophical ideas that contributed a lot to the underlying spiritual ideology of the Gothic Saint-Denis. Abbot Suger was some sort of philosopher/theologian in his own right. Corresponding with the theologian Dionysius from Syria (whose philosophy was some sort of Neoplatonist Christianity) (Helfrich â€Å"History of Gothic Architecture†), Suger came with the theory that God could best be represented as a powerful light, as a â€Å"supernatural light† as he would call it (Helfrich â€Å"History of Gothic Architecture†), who through his omnipotence, spiritualizes everything that is material. As such, God’s church ought to be a place where light is mostly present. God’s church, being the gathering place of his people, ought to also be the place where God, as light, could put his people together represented by an enveloping light. With this in mind, Abbot Suger started rebuilding the west front of the church first (the abbot left the Carolingian nave untouched and moved to reconstruct the eastern part of the church). The initial impetus that defined the changes that the abbot did on the church was the desire to put more light on the choir. He wanted the effect of having something like a â€Å"Heavenly Jerusalem† (Tarnocyova 69) that is primarily perceived to be luminescent, in one way reflecting the glory, majesty and power of the One True God. In this way, the Church acts truly as Christ’s earthly bride, bringing heaven-on-earth, making the physical reflect what is spiritual. It was this eastern reconstruction that would eventually be considered the very first Gothic art. Putting this ideal was not an easy task to do. In the first place, the Romanesque period created bulky churches with thick walls and fewer and smaller windows. The creation of light, then, would entail an architecture that was different from what was then mainstream. It was in the face of this task that Abbot Suger’s architects thought of using a more sophisticated technology, the pointed arch. The use of the pointed arch gave the architects additional flexibility that was not accessible through the curved arches. For one, the use of the arch meant lesser lateral thrust of the roof on the walls (Chapuis, â€Å"Gothic Art†). In addition to this, the new system of ribbed vaults allowed for thinner columns, allowing the stone material of the vaults to be lighter (Chapuis, â€Å"Gothic Art†) and space to be wider. Another important technology is the flying buttress that gave support to the thinner walls. These allowed for more space and more windows to be installed in these churches. More space and more windows meant more light penetrating the Church (or, in the case of Saint-Denis, the ambulatory of the church). Thus, Suger’s ideal is now a reality and Gothic architecture, with its characteristic pointed arches, ribbed vaults, and flying buttresses, is finally born. It does not mean of course that Abbot Suger thought of Gothic architecture from a vacuum. It has to be remembered that â€Å"ribbed vaults, buttresses, clustered columns, ambulatories, wheel windows, spires and richly carved door tympanums were already features of ecclesiastical architecture† (Wikipedia â€Å"Gothic Architecture†). Even the pointed arch which is used to typify Gothic architecture is not a product of a strike of genius. Assyrian architecture already made use of pointed arches as early as 720 B. C. (Wikipedia, â€Å"Gothic Architecture†). Islamic presence in Europe, most especially in Spain, would account for the introduction of these arches in the West. What characterizes Gothic architecture then is not the presence of these individual architectural traits but the putting of these elements together forming a unique architectural style that allows for spires, space, pointed arches, ribbed vaults, grand rose windows, clustered columns, ambulatories to exist in one magnificent monument. Actually, as it could be noticed, these characteristics were put together not out of whim; Abbot Suger did not put these traits together just because. Instead, these architectural traits were utilized because of a purpose: the creation of light and space in the choir of Saint-Denis. Thus, as is always acknowledged, these beautiful architectural traits came together out of technical need. Gothic architecture then is a product of a technical and spiritual need that eventually is characterized by the typical Latin cross floor plan at the same literally showing forth height and light (Helfrich â€Å"History of Gothic Architecture†). Everything in a Gothic church shows forth height. This vertical emphasis could immediately be felt by an external viewer who may rapture in awe over the spires and pinnacles of Gothic churches. The facade as well as the entire west front of a church has pointed arches, shafts, and main arcade all of which pointing up. These amplify the already overwhelming effect of spires that unanimously bring the gazer’s eyes to heaven. Entering the Gothic church would continue that ethereal experience since the nave of a Gothic church is usually very high in proportion to its width. Upon looking up, the gazer would be led to look the ribbed vaults all of which leading to a boss in a pointing way. Not only would the gazer be enamored by the height that uplifts the spirit; there is also the magnificent ray of lights that passes through strain glasses and more magnificently through rose windows. Gothic churches are famous for these magnificent rose wheel windows the best ones such as those in Notre Dame and Chartres create the effect of the flooding of light all over the cathedral. These light rays are complemented by the large and numerous other windows in the church. The flooding of light and the univocal stress on height is again complemented by the Gothic sculpture on the tympanum or columns or totally not attached at all to architecture (Encarta â€Å"Gothic Art and Architecture†). Such architecture is characterized by naturalism at the same time the constant solemn disposition (Encarta â€Å"Gothic Art and Architecture†). Conclusion Gothic art, specifically Gothic architecture, has been created initially out of the spiritual need that Abbot Suger problematized in Saint-Denis. This was then followed by the architectural-technical need to be able to answer to this spiritual need. These series of needs brought forth the fusion which is now acknowledged to be one of the greatest styles in architecture called gothic art.

Claudius Ptolemys Contributions to Science

Claudius Ptolemys Contributions to Science Claudius Ptolemy The ancient world can be traced back to times of mysterious and enigmatic people. Some mysteries, however, remained unfathomed till date. Life, during those times, was very different; humans performed activities and tasks that gave a lot of prominence to the Gods and were primarily based on the cycle of nature. On the contrary, today, life has taken 360 degrees turn. Our life today is almost dependent on technological gadgets. The transition from then to now has been enormous. There is a stark difference observed in the lifestyles of both the ages. And it is not just the lifestyle there is a vast difference even in the thinking. Since ages, many questions have often been accumulating in the human mind such as, what are the dimensions of the earth, how many continents are there on the Earth, and what are the functions of the Moon and the Sun in our day-to-day lives. Now, the answers to these questions are just a click away. But when a similar scenario must have emerged during ancient times, people might have associated it with some myth or an old wives’ tale. The transformation of people from an ancient era to the modern one was really a lengthy process where philosophers, thinkers, mathematicians, astronomers and geographers must have put across their observations and theories to the general public. However, change is never easy. Their ideas and concepts were not accepted instantly. In fact, they were all rejected outright and they were ridiculed as well as humiliated because of their beliefs and concepts. But all of them stood their ground and fought for what they believed was right. After a series of untiring efforts, they were rewarded and were proved right years after they passed away. It was the observation and contribution of these people which have now evolved into theories and concepts that help us simplify and demystify our lives. Let us shed light on the life of one such person who made a significant contribution in changing our lives. His name was Claudius Ptolemy. He was a Greek-Roman citizen, who displayed multiple talents of astronomy, mathematics, georgraphy, astrology and poetry. Decoding the Enigma In a distant town of Ptolemais Hermiou in Thebaid, Egypt, a child was born into the family of Ptolemies. The family was the descendant of Ptolemy Soter, a mighty General from the army of Alexander the Great in 90 AD. Although the family was rooted in Egypt, the Roman influence on the family was such that the infant was given a Roman name, Claudius. The name Claudius is a Roman nomen (Roman naming system) and the fact that Ptolemy bore it, indicates that he lived in Egypt under the rule of Romans . Nothing much is known about Claudius Ptolemy’s upbringing or his family. â€Å"Where did Ptolemy come from?†, â€Å"Where was he born?† are the questions which are still asked today but the answers have been lost with time. All that is known is Ptolemy started becoming renowned as someone who had a keen mathematical and astronomical sense. He became popular in Thebaid and later, in Alexandria, where he began to reside in his adulthood. Star Gazing Nothing much is known about Ptolemy’s ancestry, apart from what can be deciphered from the details of his name. However, the modern researchers are sure of one fact, that it was Ptolemy who wrote the great edict called Almagest at around 150 AD. Ptolemy wrote in Greek and utilised Babylonian astronomical data. In spite of being a Roman citizen, most of the scholars came to a common understanding that Ptolemy was ethnically Greek, although some others also had the opinion that he was a Hellenised Egyptian. In most of the later Arabic sources, he is referred to as, ‘the Upper Egyptian’, which means that he may have belonged to southern Egypt. Hence, the Arabic geographers and physicists referred to him by his Arabic name Batlaymus. Ptolemy built his reputation owing to his astronomical works, wherein he had recorded the existence of 1000 stars, out of which 300 were his finds. He is also credited with coming up with the first practical theory of Refraction of Light. He was precise in his discussions about the dimensions of the planet. Ptolemy came up with a compilation of the ancient view of astronomy in an astronomical manual called Almagest. He used the 800-year-old astronomical observations by his predecessors as a reference point for this purpose. He also added his conclusions on the basis of this reference as his vision of the universe. Ptolemy’s successors considered the Almagest to be the Gospel of astronomy for many centuries throughout medieval Europe. The ancient Greeks believed in the theory that the path of the planets was completely spherical, were discarded later as it was proved later that the orbits of the planets are elliptical. Even Ptolemy had been convinced by this earlier belief. Going Into the Orbit In Ptolemy’s manual, it was clearly seen that he followed the steps of Aristotle, whom he considered his ideal. Aristotle had come up with a theory that the planets moved in a continuous and uniform motion in perfect circles. As per Ptolemy’s observation he concluded that earth is a spherical object which remains freely suspended in the centre of the Universe. One of the studies revealed the stars to be bodies which were fixed to a strong exterior of the Universe which lay beyond the orbit of Saturn. A large number of these studies were based on Aristotle’s philosophy but Ptolemy added his inputs by calculating the motion of each planet in great detail and thus came up with his contribution to astronomy. One of his early works, the ‘Almagest’ provided a detailed study of the Mathematical theory of the movements of the Sun, the Moon and other planets. Ptolemy’s theory that the planets move in circular epicycles along their orbits, which was wel l-received during those days. The Almagest was preserved in Arabic manuscripts, like most of the Classical Greek Science. By the 12th century, it gained the desired reputation and was widely sought after. Due to its popularity, it was translated twice into Latin, once into Sicilian and then into Spanish. Like Ptolemy’s predecessors, his model was geocentric and received almost complete acceptance universally until simpler heliocentric models were introduced during the scientific revolution. Ptolemy’s theory of Planetary Hypotheses extended beyond the explanation given in the Mathematical model of the Almagest. The Planetary Hypotheses depicted the physical realisation of the Universe in the form of nestled spheres and used the epicycles of this planetary model to portray the dimensions of the Universe. According to his calculations, the sun was at an average distance of 1,210 earth radii, while the radius of the sphere of the fixed stars was 20,000 times the radius of the Earth. To calculate astronomical calculations in Handy Tables, Ptolemy introduced an efficient tool which tabulated all the data required to calculate the positions of the Sun, the Moon and the planets, as well as the rising and setting of the stars and the eclipses of the Sun and Moon. This Handy Tables became the basic model which was improvised later as astronomical tables or zijes. Ptolemy also worked on a star calendar or Almanac, which he prepared with the help of the positions of the hands and disappearances of stars during the solar year. This was presented in the Phaseis (Risings of the Fixed Stars). His observations made a huge impact in those days and made Ptolemy somewhat of a seer or scholar. Mapping it Out Apart from Ptolemy’s tremendous contribution to the understanding of astronomy throughout the world, he also laid down the groundwork to the future cartography or the study of maps. He wrote another treatise on the lines of the Almagest, compiling his knowledge of Geography, along with what was already known through the Roman Empire. An important source of information for the book, Geographia, written by Marinos of Tyre, an earlier geographer and the gazetteers of Roman and ancient Persian Empire. Ptolemy began the book with a discussion of the data and the methods used by him to write down the book. The book was written in a much organised pattern on the lines of following a grand scheme. He assigned co-ordinates to all the places and geographic features he knew in a grid that spanned the globe which was quite similar to the work of Marinos. The Latitude that we know of today and is measured from the equator was done by Ptolemy but he named it as climata, which was the length of the longest day rather than degrees of arc. For example, the length of the mid-summer day increased from 12 to 24 hours as one moved from the equator to the polar circle. In books 2 through 7, Ptolemy used degrees. He assigned 0 degrees longitude to the Blessed Islands or the Canary Islands, which was the most western land on the extreme left of blue sea of Ptolemy’s map. This was identified by the six dots that were also labelled as Fortunata islands. Most medieval mapmakers followed the instructions that Ptolemy had devised and mentioned it in the Geographia. The second part of the Geographia contained Ptolemy’s Oikoumene or the map of the whole world. The area of Oikoumene extended from 180 degrees of longitude from the ‘Blessed Islands’ in the Atlantic Ocean to the middle of China and about 80 degrees of latitude from Shetland to anti-Meroe or the east coast of Africa. His map indicated he knew only about the quarter of the globe. He improved the projections of his maps than they were since the third century BC. However, Ptolemy’s maps were inaccurate as compared to the modern maps because he took the size of the Earth as being only 500 stadia for a great circle degree on the globe. The Bible of Astrology Along with the Almagest which spoke at lengths about astronomy, it is believed by some that Ptolemy also wrote a 4-part treatise on astrology called the Tetrabiblos, which in Greek terms means, Four Books. But there are others who believe that Tetrabiblos wasn’t written by Ptolemy. In fact, many scholars state that he must have just given the term Apotelesmatika, meaning Astrological Outcomes, as it was found in some Greek manuscripts. It is said that Tetrabiblos was revered as much as the authority of a Bible by the astrological writers for more than thousand years. It is an extensive database based on the ancient principles of horoscopic astrology and as a result has been continuously reprinted. However, it could not come up to the level of Almagest as it did not touch upon some popular areas of the subject such as medical astrology and event astrology which was interpreting astrological charts for a particular moment to determine the outcome of a course of action to be initiated at that time. However, these were later incorporated into the treatise. Ptolemy was of the belief that astrology was a science which tried to describe the physical effects of the heavenly bodies on the terrestrial life but unsuccessfully. Although he had no issues with the basic validity of the traditional astrological doctrines but he worked at modifying the details so that aligns with the Aristotelian conception of nature, matter and change. Ptolemy had a practical view of astrology. He believed that astrology was conjectural like medicine as many variable factors had to be taken into account. While to assess the requirement of the medicine factors such as the race, country and upbringing of a person had been taken into account for astrology the deciding factors were the position of the Sun, Moon and the planets at the precise moment of their birth. So he considered astrology to be useful in life, but in no way, relied upon it completely. A later pseudepigraphical composition known as Centiloquium, a collection of 100 aphorisms ascribed to Ptolemy, was commented upon by the Arabic, Hebrew and Latin scholars. Striking a Chord Ptolemy had resided in the Roman Empire, where music was given a high status as an art form. His work called ‘Harmonics’, is an observation on Music theory and mathematics of music. Ptolemy was very critical of his predecessors’ approach to the Musical theory. As per his theory he based the musical intervals on mathematical ratios, which was contrary to the belief followed by Aristoxenus and in sync with the belief accepted by the followers of Pythagoras. Ptolemy further propounded the theory which was first spoken about by Pythagoras about the musical notes being translated into mathematical equations and vice versa in Harmonics. He also wrote at length about an intense diatonic scale, which was later incorporated by many musicians. Another commendable contribution of Ptolemy’s work is Optics. However today, the only Optics that has survived is in poor Arabic translations and in around 20 manuscripts of a Latin version of the Arabic, translated by Eugene of Palermo, Circa 1154. Ptolemy wrote about the properties of light, including reflection, refraction and the colour in it.. The work is a significant part in the early history of optics. The more famous Eleventh Century Optics by Alhazn (Ibn al-Haytham) was majorly influenced by this work. It contained the earliest surviving table of refraction from air to water, for which the values (with the exception of the 60 degree angle of incidence), although historically praised as experimentally derived, it seemed to have been obtained from an arithmetic progression. It had the earliest surviving table of refraction from air to water for the values with the exception of the 60 degree angle of incidence. It seemed to have been obtained from an arithematic progression although it is said to be derived experimentally. Ptolemy’s work is based on the combination of mathematical, philosophical and physiological traditions. His theory of vision was based on extramission-intromission theory; the rays (or flux) from the eye formed a cone, the vertex being with the eye and the base defining the visual field. The rays were sensitive and conveyed information back to the observer’s intellect about the distance and orientation of surfaces. The size and shape of the object get determined by the visual angle subtended at the eye, combined with perceived distance and orientation. This was one of the initial statements of size-distance invariance as a cause of perceptual size and shape constancy, which was a view supported by the stoics. Ptolemy provided explanations for many phenomena concerned with illumination, and colour, size, shape, movement and binocular vision. He also classified illusions according to those caused by factors such as physical, optical and judgmental. However, his explanatio n of the Sun or Moon illusion was obscure (the enlarged size on the horizon) which was the difficulty of looking upwards. Footprints in the Sand It is believed that Ptolemy died around 168 AD in Alexandria, the city where his work flourished. He left a lasting impression on most of the researchers existing during that time. Although his works were controversial, in recent times, it has been discovered that his studies still contain important clues and observations that are practical. Many objects or characters have been named after Ptolemy as a tribute to his immense contribution to the modern day Astronomy, Astrology and Geography. Some of them include, the crater Ptolemaeus on the Moon, the crater Ptolemaeus on Mars, the Asteroid 4001 Ptolemaeus, A Character in the Fantasy series, The Bartimaeus Trilogy, Track number 10 on Selected Ambient Works 85–92 by Aphex Twin, the Ptolemy Stone used in the Mathematics courses at both the St. Johns College campus. Sir Patrick Moore, an English astronomer and TV presenter called his cat by the name of Ptolemy and the name of a music magazine was called Ptolemaic Terrascope. With the information of Ptolemy’s life being virtually unknown, it is only his work and legacy that do justice to his biography.

Essay --

Can stem cells heal a broken heart? Aaron Cathcart of Franklinton, Louisiana suffered from congestive heart failure. His doctors had only given him a week to live because of the severity of his disease. Cathcart was accepted into an experimental stem cell trial program, where a sample of his bone marrow was taken and grown in a lab a few weeks before his open heart surgery. The cells were then multiplied in an incubator and then during his surgery, were injected into his heart. In the months to follow, Cathcart’s recovery was very remarkable and his repaired heart was almost as strong as a normal heart. His wife, Betty, was overjoyed that the trial gave her husband a longer life to live with her â€Å"Is stem cell research necessary?†.

Forestry Management Essay -- essays research papers

Forestry Management in Nova Scotia The Canadian forest sector has been a strong and vital element of national and regional well being. Through the management, harvesting, processing and marketing of timber resources, Canada has developed a reputation of being one of the largest timber resources in the forest industry. However, to maintain this reputation and economic well being there are several issues to address in order to protect and sustain this renewable resource. This paper will focus on the management of the forestry sector, particularly Nova Scotia. It will discuss the initiatives and techniques used of both private wood-lot owners and large industries in developing and implementing a forest management strategy. Nova Scotia is comprised of many forested ecosystems; hardwoods, others with softwoods and some with a mixture of both species. In order to maintain and develop these various ecosystems it is important to know how forest management impacts not only the forest itself but also other ecosystems within. For example, a clear-cut harvest can be compared to the same impact of a forest fire. However, forest fires do not remove everything which clear-cutting does. Recently clear-cutting techniques have changed to benefit Nova Scotia ecosystems by leaving clumps of trees, snags, and strips of forest to provide travel ways for wildlife. Forestry is also investigating other related issues of ecosystem management. To create and maintain the diversity of trees with a region (i.e. Hardwood and softwood), landowners leave several stands of both young and old growth within natural forest stands to enhance the biodiversity and health of the forest site. Normally clearcutting results in the re-pla nting of tree seedlings, however some species (spruce, pine) overpower the growth of the hardwood trees. This minimizes the level of specie diversity among a timber stand. By allowing these older sections of stands to remain aids to the natural growth and development of hardwood species. Also, the wood debris, a remnant of old forest growth is essential to the survival of many forest species and also acts as a recycler of nutrients back into the soil. During forest harvesting it is not always necessary to remove all the wood from the lot. Rotten or older growth can be left to contribute to the nourishment of natural forests. &nb... ... Systems.

Mohandas Ghandi Essay -- Biography Biographies

Mohandas Ghandi Satyagraha. Meaning "force or firmness of truth, Mohandas Gandhi worked and lived by this word. By peaceful, non-violent demonstrations he little by little took hold of the people of India's love and honor and freed them from British rule. This is his story: On October 2, 1869 in Porbandar, India, a region of Queen Victoria, Mohandas Gandhi was born to Kaba Gandhi and his wife. Although his father, Kaba, was the chief Minister for the Maharaja of Porbandar, he and his family lived in a small house and belonged to a Hindu caste of merchants called "banjas." As he grew, Mohandas became a small, shy and skinny boy, afraid of others' opinions. He never spoke out, but although he was never a clever child, others were surprised by his gentleness. At the age of thirteen, he was married to Kastaurbai, a pretty yet strongwilled girl of the same caste. He would now live with his wife, instead of his mother and father whom he had cared for for so long. Before this, Mohandas had told lies, had smoked, and had eaten meat, which was strictly forbidden of Hindus. Now, suddenly, he felt guilty and that he had hurt himself and in some ways those who he cared for. So, in desperation, he told his father, and they cried together. One year later Kaba Gandhi died. Mohandas was sixteen. At eighteen he traveled to England to study law and secretly to see for himself what made the English so powerful. He enrolled in a college of law but quit after one term. He felt that he didn't fit in, so he studied the " Standard Elocutionist" for use and knowledge of proper ettiquitte. After a while he quit this also because he saw no use anymore. Quitting became a popular theme in his early life. Sometimes he quit because he was bored with something and just grew out of it, or sometimes when he just couldn't accomplish anything. For example, he took English dancing and violin lessons to become more distinguished, but he was very clumsy and quit after six lessons. He did not quit every thing though. He worked at some things if he thought that it would in some way help him. He studied material on Common & Roman laws and had to pass major exams on it. Despite all of the quiting and studying, he became a lawyer. He was not a very distinguished or even good one at first, but later became respected by his friends and clients after his work on a case in South A... ...he was killed though, all of that changed. Everyone was sad, and the Hindu people were ashamed that it was one of them who had killed him. People began to worship Gandhi in the ways that he had hated. They knew that if he would have been able to speak a few words before he died he would have said to the people to "have mercy on the misguided Godse", but knowing this, they still hanged his assassin. Gandhi once said: "I have no strength, save what God gives me. I have no authority over my country men, save the purely moral." And he more than anyone knew how weak that authority could be. Over time, Mohandas freed India from the British rule, earning rights and respect for his people and a lasting place in history. In my opinion, like everyone else's. he was a great man putting others ahead of himself, but above all else wanting, hoping, and dying for peace. BIBLIOGRAPHY Franda, Marcus and Vonetta J.

Terry V. Ohio

Terry v. Ohio Case Project| | | | | Victoria Swannegan| 12/2/2010| | In 1968 a case called Terry v. Ohio took place. This case made a big impact on the police departments of the United States by giving officers more reasons to make an arrest. A â€Å"Terry Stop† is a stop of a person by law enforcement officers based upon reasonable suspicion that a person may have been engaged in criminal activity, whereas an arrest requires probable cause that a suspect committed a criminal offense.A Cleveland detective (McFadden), on a downtown beat which he had been patrolling for many years, observed two stranger on a street corner. He saw them proceed alternately back and forth along an identical route, pausing to stare in the same store window, which they did for a total of about 24 times. Each completion of the route was followed by a conference between the two on a corner, at one of which they were joined by a third man who left swiftly.Suspecting the two men of â€Å"casing a job, a stick-up,† the officer followed them and saw them rejoin the third man a couple of blocks away in front of a store. The officer approached the three, identified himself as a policeman, and asked their names. The men â€Å"mumbled something,† whereupon McFadden spun petitioner around, patted down his outside clothing, and found in his overcoat pocket, but was unable to remove, a pistol. The officer ordered the three into the store.He removed petitioner's overcoat, took out a revolver, and ordered the three to face the wall with their hands raised. He patted down the outer clothing of Chilton and Katz and seized a revolver from Chilton's outside overcoat pocket. He did not put his hands under the outer garments of Katz (since he discovered nothing in his pat-down which might have been a weapon), or under petitioner's or Chilton's outer garments until he felt the guns. The three were taken to the police station. Petitioner and Chilton were charged with carrying concealed weapons.The defense moved to suppress the weapons. Though the trial court rejected the prosecution theory that the guns had been seized during a search incident to a lawful arrest, the court denied the motion to suppress and admitted the weapons into evidence on the ground that the officer had cause to believe that petitioner and Chilton were acting suspiciously, that their interrogation was warranted, and that the officer, for his own protection, had the right to pat down their outer clothing having reasonable cause to believe that they might be armed.The court distinguished between an investigatory â€Å"stop† and an arrest, and between a â€Å"frisk† of the outer clothing for weapons and a full-blown search for evidence of crime. Petitioner and Chilton were found guilty, an intermediate appellate court affirmed, and the State Supreme Court dismissed the appeal on the ground that â€Å"no substantial constitutional question† was involved. Terry was protected b y â€Å"The Fourth Amendment† but the officer had a probable cause. The Fourth Amendment to the U. S.Constitution protects personal privacy, and every citizen's right to be free from unreasonable government intrusion into their persons, homes, businesses, and property, whether through police stops of citizens on the street, arrests, or searches of homes and businesses. The Fourth Amendment provides safeguards to individuals during searches and detentions, and prevents unlawfully seized items from being used as evidence in criminal cases. The degree of protection available in a particular case depends on the nature of the detention or arrest, the characteristics of the place searched, and the circumstances under which the search takes place.In the case, they used a term called â€Å"Stop and Frisk†. This is a situation in which a police officer who is suspicious of an individual detains the person and runs his hands lightly over the suspect's outer garments to determine if the person is carrying a concealed weapon. Unlike a full search, a frisk is generally limited to a patting down of the outer clothing. If the officer feels what seems to be a weapon, the officer may then reach inside the person's clothing.If no weapon is felt, the search may not intrude further than the outer clothing. A full search is called â€Å"Search and Seizure†. It is the legal term used to describe a law enforcement agent’s examination of a person’s home, vehicle, or business to find evidence that a crime has been committed. If evidence is found, the agent may then â€Å"seize† it. Search and seizure also includes placing an individual under arrest. The Terry v. Ohio case made a phenomenal change. It made a difference in which people can be searched arrested.

The Destructors and Lord of the Flies

The Destructor and the Lord of the Flies Being a successful leader doesn't mean that you have to be aggressive and to use the power of authority. Both, in the destructor story and Lord of the Flies novel we could find some similarities in the way how the young children managed to be leaders and to achieve what they wanted. In the Lord of the Flies we can find two characters of two young children that used to be leader. In one side we had Ralph whose aim was how to escape from the island and in the other side we had Jack whose grief was how to secure food.Ralph was very calm and well educated boy but he had one problem hat he couldn't managed to have under control Jack. This might be because of lack of knowledge since he was too young. Ralph ideas of taking care about the fire was brilliant, this is because if we have a list of equipment's that we need to survive in such places in the first place should be a mirror or light that would reflect the light , so that would be a chance for them to be identified from a long distance.Jack character was too aggressive and he wanted to be a leader and to take things under control, but the problem was that he didn't see any long term solution besides securing food. He was not cooperative with the others and wanted to control situation using his power which in most of cases doesn't work and this was shown as well since he started to get control in his tribe, some of them lost their lives. In the end of the film we can conclude that Ralph idea that he gave when he took leadership was realized.Soldiers wouldn't saw them, if there were not any fire on the field. In the Destructor story we can find some other characters of young children. In one side we had Blackleg who was appointed as a leader of a gang with voting but since he didn't have any new ideas he didn't manage to keep the leadership. When T comes and he gave his idea he immediately keep leading and he achieved to realize his goal by managing the team by delegating d uties to each of them in order to make them all involved.Finally we could say that having a good ideas and being creative and being able to manage and implement in proper way this is how usually works in many cases but you need to have an experience and to be able to keep things under control. In Jacks case he proved that being a leader and using authority and power doesn't really work and possibilities to fail are more than to win. Shaped. The Destructor and Lord of the Flies By Shipped

Advantage And Disadvantage Of CCTV

Closed-circuit television (CCTV) is a camera which is used to produce images or recordings for surveillance purposes. CCTV can be either video cameras, or digital stills cameras. Video cameras are either analogue or digital, which means that they work on the basis of sending analogue or digital signals to a storage device such as a video tape recorder or desktop computer or laptop computer wherelse digital stills cameras can take excellent pictures in most situations and can be plugged into the USB port of any computer and pictures can be taken of any camera scene.The name of the CCTV camera’s inventor is Marie Van Brittan Brown. CCTV is usually installed in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. In this days and age, it is critical to take security seriously. Some people think that only businesses and commercial properties need good security, but it is not only that our homes need good security too. Wit h the rapid increase of crime rates and breaking and entering, it is very important to mull over the available security options and choose one that is the best fit for us.Therefore using CCTV cameras and equipment is one of the most popular and cost effective ways of providing security in the home and place of work. The reason why CCTV cameras is used because it can act as a very successful deterrent to thieves and burglars, certainly making them think twice at the very least. The technology these days have made our work much easier. For example, it is even possible to hook the cameras up to an ordinary television or computer to watch the footage. In this report we are going to discuss on the pros and corns of a CCTV camera system.BODY:The use of CCTV (close circuit television) cameras in streets, stations, shops and other public places has increased rapidly in recent years. I completely agree with the statement above. We can’t overlook at the importance of CCTV in our daily lives. Indirectly CCTV makes our lives much easier because it protects the public, buildings and vehicles. One of the importance of CCTV are to prevent crime. All of us are worried about crime. CCTV cameras can not only catch criminals in the act, but the existence of CCTV systems can make a would-be criminal think twice beforecommitting any wrong-doing. There are many different types of crimes, including from crimes against persons to victimless crimes and also violent crimes to white collar crimes. Crimes against persons are also called personal crimes. For example, murder, forced attack, rape, and robbery. Next is a victimless crime. It is an offense that lacks an exclusive victim who is the object of the crime. This offense is usually against society itself through norms, values, attitudes, and beliefs.For example when someone smokes or uses cocaine they are going against cultural values about apposite behavior. They are eventually committing a crime, but there is no direct vict im, as there is when someone is robbed or murdered. Other example includes prostitution, illegal gambling, and illegal drug. White-collar crimes are crimes committed by people of high social status. For example, stealing money from one’s employer, insider trading and tax evasion. All this kind of crimes can be prevented by using a CCTV camera.There were some researchers conducted on the use of CCTV cameras and they found that surveillance systems were most effective in parking lots. The use of CCTV cameras resulted in a 51% decrease in crime As we all know CCTV cameras helps in preventing crime. Besides preventing crime CCTV cameras have other functions too which are beneficial to us. CCTV cameras can be used as a useful piece of evidence in lawsuits. In legal cases of robbery and other forms of crime, videos and images provided by the CCTV camera system can serve as a valid proof and evidence against the defaulter.To be more specific if a crime is committed around us and the person accused of committing the crime was caught on camera, we will have an extra and strong piece of evidence for a court case. To confirm that the person accused did indeed commit the crime, jurors and judges can watch footage or view photos that was recorded and captured from the security cameras. By doing so not only will we be preventing the same person from causing us more trouble in the future, but we'll be helping out our entire community. Eventually, this useful piece of evidence by the CCTV camera can help law enforcement to solve crime.Whenever someone is caught on CCTV camera committing a crime, police and other law enforcement officials resembling customs officers, probation officers, immigration officers, and corrections officers can use the footage to release video or photos to the public via various media outlets like newspapers, magazines and internet. Many of us don’t realize that having a picture of the suspect can make a world of difference when it comes to making an arrest and getting dangerous criminal off the street. Besides those that was stated above, with the use of CCTV camera we are able to keep an eye on children, elderly folks and things.Many of us are too busy out there that we are not aware of what is going on at home. With a CCTV system at home, we will be able to monitor the safety of children and elderly folks while we are away. More to the point, we can also keep an eye on maid and make sure nothing out of the ordinary is going on. That is if we were to keep track on what’s happening at home. What if it’s about work? If we can't be at the office all the time but like to know what's going on, installing a security camera can help do just that.We can keep an eye on things from our home computer with a few quick clicks of your mouse and at the same time we can make sure our work related matter is running smoothly and nothing out of the ordinary is going on. If we have our own business and staff working un der us, CCTV is the best equipment that can protect our staff physically against violence from customers. At the same time, it can also protect them against false accusations that perhaps may be coming from colleagues or even from client and customers.It is also helpful to keep track on the activities of the staff. Although we are told that a CCTV camera help in the fight against crime and has many benefits, however some people are opposed to their use. They believe that everyone has a right to privacy. As we all know where there is good there is bad also. Invasion of privacy is the major issue that everyone would bring up when it comes to any security system device like the CCTV camera system. The role of CCTV cameras is to constantly monitor the activities of people working and living in a location.This actuality alone upsets people, mainly because many of us simply don't like our privacy being marched into. We don’t look at the reason why the CCTV equipment is there. For e xample, when a CCTV camera is installed at a work place all the activities that are done by the employees are being recorded. Basically, it lowers the employee self-esteem and hampers productivity at times. Employees may feel ill at ease due to the constant monitoring of every activity. Besides that, hacking is one of the issues that is related to privacy.The value of CCTV information has increased as the value of shares in market. This results in a higher risk from hackers. Hacking CCTV footage has led to privacy issues. The most common issues and are happening often among our community are images captured by CCTV of naked women distributed across the Internet. Complete protection of public security systems from hackers is definitely not possible. The reason is because the system connects to a network, therefore hackers can hack into the system virtually from outside locations easily.Another example is if there is a CCTV camera installed near an ATM machine, hackers can easily hack the video of that camera and can easily get the pin code and any other information about a customer or ATM user which he wants. Therefore, installing a CCTV camera in the wrong place could lead to a privacy violation. Property managers should play their role by being sure they're not acquiring any legal risks before setting up CCTV equipment. Besides those disadvantages that were mentioned above there is another disadvantage of CCTV camera.Not everyone can afford to get it because the price range of CCTV camera is from RM1,500 (the cheapest) to RM10 000 and more depending on the brand. The initial cost per camera is high. Moreover the installation of CCTV camera may also increase the initial expenditure depending upon the complexity of the CCTV camera system as well. For example, if a property manager or owner is taking into account to equip a whole building with ample amount of surveillance equipment, then he's looking at quite a bulky bill.Not only that, once CCTV cameras are bou ght they must also be installed correctly by experts and monitored regularly, which eventually drives the cost up. Another disadvantage of CCTV camera system is that they can only monitor a limited area not every area of your office or home at all times. So many people don’t consider it as a foolproof method for crime prevention. Usually most CCTV cameras are installed out of the reach of humans, but sometimes a camera can still get damaged. Criminals who have intention to rob or do crime can vandalize the cameras in various ways, such as sticking gum or spraying something on the lens.With that the CCTV camera will not be able to monitor any wrong doing of theirs. Besides sticking gum and spraying, they may even be able to change the angle of the camera. As we all know technology are evolving all of the time. The same goes for CCTV systems. When older models are replaced by new systems, the result is often a mix of both modern and old cameras, and this can lead to incompatibi lities between systems. Older cameras might also produce low-quality footage that might not be accepted by a court as evidence if continued to be used for long.Other than that, the camera might miss details. For example, a covered weapon which is not immediately visible on a person might not show up on CCTV footage and a CCTV camera might not catch all activity due to its position. CCTV cameras can be sensitive to hostile weather and so are generally installed in sheltered or indoor locations. Lastly, CCTV equipment is sensitive to knocks and can malfunction if interfered with in this way. Therefore, the process of monitoring can be interrupted.CONCLUSION:In a nutshell, CCTV camera has its own pros and corns.  Some people agree that these cameras help in the fight against crime, but not all the five fingers are the same. However some people are opposed to their use because they believe that everyone has a right to privacy. I personally feel that CCTV cameras should be installed in most of the places to decrease the crime rate that is increasing rapidly in our country. One strong reason to support my opinion is despite all these disadvantages CCTV camera still allows us to secure our place to a great deal. I agree that it has disadvantages but we all know nothing is perfect.The disadvantage can be solved by using different methods. These days CCTV cameras are becoming increasingly affordable to install. In order to install CCTV surveillance systems it is a one-time expense. It is better to install a CCTV camera instead of hiring multiple security officers to monitor several different areas of your establishment or town. A handful of officers can practically â€Å"patrol† an area from a comfort that monitors a wide area, reducing manpower costs to provide the same level of security. I would like to stress that CCTV camera is very useful equipment and its advantage outweigh the disadvantage.
