Chemistry and Biotechnology

1. What specific topic did you choose to research and evaluate? I decided to conduct research on stem cells for medical use.2. List the resources that you used in your research of your topic.http://www.ama-assn.org//ama/pub/physician-resources/medical-science/genetics-molecular-medicine/related-policy-topics/stem-cell-research/basics-stem-cell-research.page http://stemcells.nih.gov/info/basics/pages/basics6.aspx3. Describe, in a few paragraphs, the biotechnology that you researched. How is it currently being used and/or what are the hopes for its use in the future?Stem cell research is a fairly new study which has gained a large amount of popularity lately. Stem cells are cells that have the potential to become specialized into different types of cells within the body. What this can do is help replace damaged cells with healthy new cells since stem cells are able to adapt to what is needed. The research going on is to discover how this can be used medically to help cure major disease s out there in the world.There are many ways to acquire stem cells. The most popular form is through the umbilical cord from the birth process. The other way to acquire this is through the bone marrow and from blood. Some other minor methods include germ cells or organs of an aborted fetus, embryos made by in vitro fertilization and mature adult tissue cells reprogrammed to behave like stem cells. Most commonly however, stem cells are acquired through bone marrow and umbilical cords.4. Describe the positive aspects of this biotechnology, being as specific as possible.The positive outcomes of this can include a wide variety of possibilities. This has the potential to create multiple cures for diseases such as Parkinson’s, Alzheimer’s, vision/hearing loss and much more. Also, if a soldier was to be wounded with a burn or fatal injury, stem cells may be able to repair these problems and help lower casualty and death rates in our military. In addition, with how convenient bone marrow can be found (seeing as every person has it), this can help those people, who are in need of stem cells, easily acquire it on such short notice.5. Describe the negative  aspects of this biotechnology, being as specific as possible.There is currently not enough research on stem cells to fully determine their potential as to what they can do. This is bad on both ends of the spectrum. If stem cells were to be proven useless, this would be considered a waste of time and money. If they prove to be extremely powerful and can transform into any cell possible, there may be talk that this kind of technology can be overwhelming. Overwhelming in the sense that what if these stem cells are powerful enough to make a brand new human being? What if people use these stem cells on themselves to make themselves look 21 years old until they die or remodel certain aspects of their body to make it so it fits their desire? It will be a sense of cheating out life by just getting the easy way out of a lot of issues. 6. Based on your research, what is your conclusion about whether or not this biotechnology should be used? Be sure to explain your answer.After conducting my own research I believe stem cells should have more research put into them to discover their complete potential. If proven to be used for medical reasons such as to cure certain diseases, this should definitely be implemented into the medical field (assuming there are no major side effects). This can be a huge advancement in the medical field and may be a breakthrough in saving many lives of dying individuals. I do believe that regardless of its potential, whether stem cells prove to be useful or useless, they should be kept away from the public and should only be kept in medical facilities and only used for medical purposes. I would not feel comfortable having people running around the streets with stem cells in their back pocket not knowing what they can do with them.

Business Rules and Data Models Essay

A database is a structure that contains information about many different categories of information and about the relationships between those categories (Pratt & Adamsk 2010). Database objects are entities that exist within a database to support operations such as storing, retrieving and manipulating data. Organizations use large amounts of data and database management system to store and transform data into information to support making decisions. A database management system consists of the following three elements: 1. The physical database: the collection of files that contain the data. 2. The database engine: the software that makes it possible to access and modify the contents of the database. 3. The database scheme: the specifications of the logical structure of the data stored in the database. As we know, database is structured collection of data; computer based databases are usually organized into one or more tables. A table stores data in a format similar to a published table and consists of a series of rows and columns. In a database model, each object that we want to track in the database is known as entitiy. For example, in a college database there might be several entities which is known as set of similar objects. Some of the entities in college database are: 1. Student 2. Professor 3. Courses 4. Employees Attributes describes one aspect of an entity type. Entity type is described by set of attributes. An entity is a real-world item or concept that exists on its own (Shiflet, 2002). The set of all possible values for an entity is the entity type. Each entity has attributes, or particular properties that describe the entity. For example student Indra Paudel has properties of his own studentID, StudentName and StudentGrade. Figure 1 E-R Diagram notation for an attribute domain ( StudentGrade ) of an entity type (Student). Let’s have a close look of each entity and their attributes. Figure 1.1 the attributes of Student entity. Figure 1.3 the attributes of course entity. An entity is a distinguishable object in the enterprise. An entity has attributes that describe the properties of the entity. For example, a course is an object in the student information system. The course number, title, credits, and prerequisites are the attributes for the course. All the courses have same type of attributes. A collection of entities of the same attributes is called an entity set. Since each entity is distinct, no two entities can have the same values on the attributes. Each entity class has an attribute or a set of attributes that can be used to uniquely identify the entities. In case there are several keys in the entity class, we can designate one as the primary key. For example, we can designate the course title to be the key, assume that every course has a different title. A composite attribute is an attribute that is composed of two or more sub-attributes. For example, the Student entity class has the address attribute that consists of street, city, state, and zipcode. A multivalued attribute is an attribute that may consist of a set of values. For example, the Course entity class has the prerequisites attribute. A course may have several prerequisites. Therefore, the prerequisites attribute is a multivalued attribute. A derived attribute is an attribute that can be derived or calculated from the database. A derived attribute should not be stored in the database. For example, we may add an attribute named numOfPrerequisites to the Course entity class. This attribute can be calculated from the prerequisites attribute. Example of business rule: Department——offers——Course Course——Generates——-Class Professor——Teaches——Class A conceptual data model identifies the highest level relationships between the different entities, whereas physical data models represent how the model will be built in the database. A physical database model shows all table structure including column name, column data type, column constraints, primary key, foreign key, and relationships between tables.

Statistic Analysis Term Paper Example | Topics and Well Written Essays - 1250 words

Statistic Analysis - Term Paper Example As a student interested in international studies, with a goal of eventually entering a business or public administrative realm that deals with international technologies and markets, I have prepared this brief paper to analyze a number of variables that pertain to population demographics of a number of Western and non-Western societies in order to determine variables that have an effect on quality of life. Specifically, I have gathered a series of data from the world rankings dataset of educational, sociopolitical, and quality of life characteristics produced for statistical analysis by the Statistics Online Computational Resource center at UCLA, titled the SOCR Data 2008 World Countries Rankings. This data presents a range of information on variables dealing with country size, economic dynamism, literacy rates, health and wellbeing, quality of life, and religiosity for the top 100 countries in the world. I analyzed the data for these countries to determine some of the major characte ristics of the demographic trends within each nation in order to summarize the overall international standings of countries relative to their population demographics. I present a variety of data analysis compilations drawn from this dataset in the brief summary that follows. In order to weigh the overall trends regarding general quality of life as determined by the SOCR dataset, I developed a histogram and stem and leaf plot for the quality of life measure tabulated in the dataset, defined as a multivariate measure including inequality, gender-based, poverty, homicide, environment, and employment indices. Figures 1 and 2 below present the findings relative to this measure. As can be seen from this data, the distribution seemed to follow a relatively normal pattern. This indicated that there were a wide range of countries in the middle of the quality of life demographic

PROBLEM-BASED LEARNING Essay Example | Topics and Well Written Essays - 1250 words - 1

PROBLEM-BASED LEARNING - Essay Example Cheryl’s husband was sent to jail the previous year and Cheryl is stressed up. Cheryl’s children are aged 13, 14 and 17 seem aggressive to her and even to the nurses in her presence. She confessed that she is a self harmer for several years as a tissue scar was noticed during examination. This trigger was a very personal matter to some of the group members as they had relatives who had undergone such situations. This made our group work harder than I thought (Jasper, 2003). As a result on our first day of presentation one such member failed to turn up. I personally felt bad and betrayed since we had really worked hard in our daily group discussions. I felt that that member was a letdown and did not deserve to be in our group any more. My feelings kept being pushed form bitter to pity since I put myself in their shoes and I understood the pain and trauma. Conversely, I thought that members should learn to separate their feelings and work so that there would be no conflict of interest. I felt that the member was just lazy and used their bad experience to intimidate the other group members to do their work as we quickly researched their part and presented the presentation. To my surprise this was just the beginning of the bad side of being in a group. During the following group discussion meetings, there were conflicts surrounding the group leader and the ordinary members. It is normal for groups to have conflict especially at the forming stages (Hackman, 1990). This member actually wanted to be the chairperson. Moreover, she expected the other group members to agree with her suggestions and responses without question (Burtis & Turman, 2010). In short she was always right and everyone else was wrong or should just follow her. As expected some members hit back and this led to more problems in the group as little work was being done and more conflict added (Corey, Corey & Corey, 2010). By this time I was almost giving up and since I am not

Frida Kahlo and Surrealism Movement Essay Example | Topics and Well Written Essays - 2000 words

Frida Kahlo and Surrealism Movement - Essay Example The essay "Frida Kahlo and Surrealism Movement" states the surrealism movement and Frida Kahlo. Frida unconsciously painted from a surrealist style, though not a disciple or even admirer of surrealism- a result maybe due to her dramatic nature and extreme emotional and physical pain that she suffered. She often experimented with styles, icons and motifs and her work reflected strong sexual overtones, though she had no special explanations for her methods and once said "I put on the canvas whatever comes into my mind." Her paintings often shocked people due to their sexual boldness and exquisite starkness, her ruthless representation of herself in her paintings like ‘My Birth’, ‘What Water Gave Me’ ‘Henry Ford Hospital’ and ‘The Two Fridas’ are emotionally breathtaking. In 1953, when Frida Kahlo had her first and only solo exhibition in Mexico during her lifetime, a local critic wrote: 'It is impossible to separate the life and work of this extraordinary person. Her paintings are her biography.' Frida Kahlo was a passionate, dramatic and clever woman, the product of a Hungarian –Jewish father and a devout Catholic of Spanish-Mexican Indian decent mother. She was closest to her father who shared her interest in art but had a cold relationship with her mother. This potent cultural fusion, plus being surrounded by women (three sisters of her own and two half sisters) and witnessing the Mexican revolution, seems to have had a great hand in shaping Frida’s personality early on.

Writing as Art Essay Example | Topics and Well Written Essays - 1500 words

Writing as Art - Essay Example According to Mills (1), a writer develops words, makes them true, emphasize, and illuminate the words through images. He further argues that there are characteristics that identify writing as an art, and they have a significant impact on the readers and the writers; these features include world, story, image, and voice. Writing campaigns is one of methods through which writers, activists, and lobbyists protest social problems. Writing campaigns have been in use for many years. Some have been effective while others have not. However, they serve the same purpose of educating and spreading the message, they want done. The paper will discuss writing as art, and the way writing campaign has used to protest social problems. Writing as Art Writers develop words, make them true, emphasize, and illuminate the words through images. Through the voices, they hold the reader’s attention and remind them of the changing tones of speech. Through the stories heard and told, they indicate the w ay the writer’s thoughts are molded by the narrative, how the writer shapes the lives and thoughts of others and their lives. There are features that are used to identify writing as a form of art, and they have a strong impact on the readers and writers. ... Writing as art assists us to determine the images, stories, worlds, and voices individuals inhibit and which inhabit writers, in other words, the acquired culture (Mills 2). Writing in its creative form is not limited to the voice of one principal authority, or to a type of address by a single speaker, for instance, a middle-class white educated British-American. Currently, individuals from various ethnic and racial backgrounds, representing differences of sexuality, gender, and age, practice writing as an art. The readers and the audiences actively look for all these voices whose numbers indicate the same range of experience and culture (Mills 4). The idea of the writer’s voice finding a voice indicates the writer’s position towards all the creative characteristics of writing as art including those of the voice. The voice is generated by the recurrent places, qualities and aspects of the world being represented, images chosen to highlight, what the writer writes about, and the story-like events or story that hold a special fascination to the writer. The choice of words relies more on what the writer thinks on the undercurrents and currents of speech. Creative language entails what individuals say, and the manner they speak with themselves and to each other, and this creates a rich supply of spoken rhythms. From each single voice are many voices, some are calm and angry, some perverse and moral, others overheard and native. An important skill to the writer is learning the virtue of listening to the voices, those within them and those that surround them, and those of the characters in the play or the story (Mills 7). It is important to note that all the writing is affected by the

How is inclusion understoodan examination of different approaches to meeting diverse needs - Essay Example vely developed in countries with different cultural and moral beliefs; The above questions are related to the following facts: the level at which social inclusion is supported by the government of a particular country is depended not only on the willingness of the political parties involved to face the specific problem but also on the level at which the relevant policies will be accepted by the local society. Current paper focuses on the social inclusion policies developed in Britain during the 21st century; emphasis is given on teenage mothers and the terms under which their inclusion in the British society is promoted. It is concluded that the position of British governments in regard to the specific issue has not been standardized being depended by the social conditions of each particular period; however, it is clear that the Labour party has been more supportive to teenage mothers compared to the Conservatives who emphasize on the moral aspects of the particular problem. The poli cies developed in Britain for the social inclusion of teenage mothers during the 21st century are analyzed by referring primarily to the concept of social inclusion – as a reflection of the social relationships and ethics of modern societies. The concept of social inclusion, as an element of social policies of governments worldwide has been explained using different approaches. In accordance with Munck (2005) the social inclusion should be considered as the result of globalization; it is noted that through the establishment of ‘global cities’ – ‘like New York, Tokyo, London, Paris’ (Munck 2005, p.33) new modes of life were developed; moreover, not all people have been able to align their daily activities with the new style of life; the exclusion of certain people of these cities, which was developed gradually, led to a series of severe social problems and turbulences which could be confronted only by developing effective social inclusion policies.

Commodity chain & a pair of Steve Madden shoe - Assignment Example Mars family and there exist varieties of other Snickers goods such as the, dark chocolate, ice cream, bars that contain almonds as well as bars made out of peanut butter. The ingredients that go into the production of Snickers include milk chocolate that consists of sugar, cocoa butter, skim milk, lactose, milk fat, soy lecithin as well as artificial flavor. Other ingredients are salt, peanuts, soybean oil that has been moderately hydrogenated, egg whites, corn syrup, chocolate and synthetic flavors2. The Snicker bar is actually the bestselling chocolate of all time that is manufactured by the Mars group, which is situated in New Jersey in the United States, but the ingredients that go into the final product are sourced from different places in the Americas. For instance, the paper that is used to wrap the bar after it has been manufactured is produced in Canada, sugar that goes into the Snickers Bars comes from Brazil, peanut from Argentina, corn syrup from Iowa, chocolate cocoa from Guyana, vanilla from Mexico and milk from Wisconsin. All these ingredients are sourced and brought together in the manufacturing stage to come up with the final product that is the Snickers Bar. Once all the ingredients that are needed in the manufacturing process have been collected by the company, the processes of manufacturing the Snickers bar then begins. It is usually very rare to find companies that produce chocolate buying the cocoa that is needed in the manufacture directly from the farmers, as they have to buy through the intermediaries or the sub-suppliers. The cocoa is fermented in a process that may take almost a week and after this process3, the beans are supposed to be dried as soon as possible to makes sure that it does not grow mould and also to give it the rich chocolate flavor. After the semi-sweet chocolate has been processed, it is mixed with butterscotch chips, peanut butter, milk, sugar, vanilla, marshmallow cream and butter. The mixture of these ingredients

Lifelong learning is attitudinished that one should be open to the new ideas, decisions, skills or behaviours. English is neccessity of life and the same as lifelong learning when you want to live in the real world; English is very important and neccessity in your life. For example, when I was young I could not speak any language and then after I grew up my parents, my teachers; they tried to teach Thai language to me because they knew if I cannot understand Thai language it would be very difficult to live with another people when I grew up where I studied my teacher taught English to our students because he knew English is very important in the world, but I did not know why at that time I did not study hard. Sometime, English was boring; this is the reason why I did not have interest to study it, perhaps I think, I am lazy and it is not good for me. English is important key to success. If you want to do anything in the world such as, to study, to do your business, to make a new friends, to go aboard etc. Especially when you go aboard to study another course. It is teach in English and then when you graduate and want to get a good job, it is very important for you to do anything in your business.

If you think and do in the right way it is good for you and anybody, but on the other hand it is good for you only and then it can destroy someone.

Why singapore failed to be a major trading centre?

Why singapore failed to be a major trading centre? â€Å"No historian has yet adequately explained why Singapore failed to be a major trading centre before the nineteenth century†. Raffles Professor of History, Wong Lin Ken. a. Do new Dutch/Portuguese reports, maps and scant archaeological evidence dating back beyond the 19th Century now suggest that Singapore was ALWAYS a strategic place after all? Numerous evidences had been uncovered, and reports and archaeological findings especially, certainly suggest that Singapore was largely strategic between the period of Temasek, in 14th century, and late 17th century. However, to conclude that Singapore was hence always strategic would probably be too much of an overstatement. This essay will discuss Singapores strategic significance, with the support of these evidences, during the different time periods. During the 14th century, trade was already ongoing between the West, South Asia and East Asia. The Melaka Straits was crucial for traders to sail to and fro the Indian Ocean to the South China Sea. Sailing in the past depended on wind direction, thus ships had to stop in Southeast Asia (SEA) to wait for a change in wind direction to bring them towards either China or India. Singapore was hence a strategic port because she was located in SEA and along Melaka Straits, making it a convenient stopover hence the central of international trade. Bits of celadon (from China), Chinese coins, fragments of stoneware (mainly from Guangdong and South Fujian) and earthernware (from Sumatra, Java and Borneo)and under-glazed blue and white stem cup (more expensive of porcelains from Jingdezhen during Yuan Dynasty)recovered support the above claim as they suggest extensive trade links Temasek had with China and SEA, and that its inhabitants, especially the wealthier ones inhabiting Fort Canning, were able to afford the more exquisite products of Jingdezhen. Temasek then, was able to attract maritime trade by providing unique products that rival ports were unable to supply. Recorded by Wang Da Yuan in Daoyi zhilue,Temasek supplied indigenous products like hornbills casques of excellent quality. Found only between north of Malay Peninsula and South of Borneo, traders can only lay their hands on it at Temasek or Palembang. Though Lakawood was in abundance, Temasek was one of the five ports that offer those of middle-quality. Celadon, white wares and stonewares uncovered at Riau Archipelago, dating back to the period of Temasek, had patterns and craft similar to those imported from Temasek. Furthermore, the origin of glassbeads of Riau Archipelago and Temasek should be identical given similar compositions. Hence, Temasek probably served as a collection centre and an entry to export for Riau Archipelago. In this case, evidences do suggest that Singapore was prospering and had an influence on regional economy and was thus strategic. During the 15th to 17th centuries, though Singapore declined slightly when Temasek was relocated to Melaka, fragments of under-glazed blue porcelains found at Kallang River, and Portuguese maps which indicate the presence of a shahbandars office, as elaborated in (b), suggest that she retained some of its strategic significance as a port by maintaining some trade with China. As mentioned, being one of the strategically situated along the Melaka Straits, the power that was able to erect a strategic dominance around the waters around Singapore would be advantaged in terms of security and economically. The Dutch had wanted to destroy Luso (Portuguese-Spanish) monopolies in SEA when they first started attacking Portuguese trading ships around Singapore waters and declared war with the Portuguese when they raided Santa Catarina and auctioned off its products. This saw the naval battles between the Dutch and Johor Sultanate, and Portuguese and Acehnese in the early 17th century and gave rise to the considerations of fortifying Singapore by both powers. Jacques De Coutre proposed to build forts at the east coast of Singapore and Muar River estuary and station a naval fleet at Sentosa to protect Portuguese trading ships from the Dutch. Dutch had the same places in mind for their fortification plans. Till this point, the Dutch and Portuguese reports do suggest th at Singapore was strategic. However, the plans never realised, which made us rethink if Singapore was really that strategic after all. Singapores strategic significance took a turn in the 18th century. There was not much evidence to prove this period of time, but by referencing to my contextual knowledge, we know that the Dutch shifted their focus from the Melaka Straits to the Sunda Straits, Portuguese diverted their trade to Japan having difficulties trading in the Melaka Straits and Johor Sultanate relocated their capital to the Lingga Archipelago, shifting the maritime silk road southwards. Singapore lost its value with the declination of Melaka Straits and was abandoned. She no longer held any strategic significance to participants of the maritime trade. Perhaps it is precisely that not much evidence was found that dates back to this period of time that it suggests that trading activities in Singapore was kept to its minimum. Moreover, no coins or porcelains were uncovered that dates beyond the Song and Yuan Dynasty, and the Ming Dynasty respectively, further supporting my contextual knowledge. It is evident that Singapores strategic significance changes with time, depending on human-related factors such as politics and economics, and hence is relative. The evidences may seem to imply that Singapore was always strategic, but when viewed from another angle, they can also suggest otherwise as stated in the previous paragraph. Therefore to say that they suggest that Singapore is always strategic may be a little too extreme. b.In light of this evidence, should Singapores history from 1511 to 1819 be written as (1) little more than a sleepy fishing village? (2) a declining but still thriving emporium astride hotly contested strategic waters (3) part of the Johor Sultanate?Please explain your preference. From the 15th century to 17th century, Singapore was a (3) part of the Johor Sultanate, but she was (2) a declining yet thriving emporium astride hotly contested strategic waters between the 16th and 17th century. It was only during the early 18th century that trade in Singapore started dipping, and she was perceived by the British as a sleepy fishing village when they stepped ashore in 1819. Hence, (1) little more than â€Å"a sleepy fishing village† suitably describes Singapores history between this period as it is a broader title and thus encompasses both (2) and (3), and the reduction of importance of Singapores port resulting from the declination of the Melaka Straits during the 18th century accounts for Singapore being â€Å"a sleepy fishing village†. When Singapore was (3), trade was still ongoing though insignificant compared to its Temasek period. Excavations on the north bank of Singapore River, where a settlement was once present, and Kallang River revealed fragments of ceramics and under-glazed blue porcelains with designs dating back to the rule of Ming Emperor Wanli (1573 to 1620). Similar findings in Johor Lama and Johor Shoal imply that the findings in Singapore belonged to the Johor River trade controlled by the Johor Sultans. Some may suggest that these pieces might have been disposed into the Kallang River when ships stopover for supplies because they broke during the voyage, and not because of trade present in Singapore. This may be true, however, according to two Portuguese maps, a shahbandar of the Johor Sultans office was featured on the southern coast of Singapore, proving the above conjecture wrong and showing that trade at the Kallang River was flourishing to the extent it needed a shahbandar to run it. This also indicates that Singapore then, was continuing some degree of trade with China, showing that she was (1). As mentioned, trade was also falling, compared to its Temasek period, as during this time, Melaka was the main port for international trade. Singapore then, supported Melaka by providing goods from herself for Melaka to export. An example being blackwood, which was brought from Singapore to Melaka, and then bought in bulk by Chinese traders. (2) may now seem to be plausible at this point in the essay since Singapore was a declining yet thriving emporium, and evidence show that its waters are hotly contested for between the Dutch and Johor Sultanate, and the Portuguese and Acehnese, and Singapore was seen by both as strategic to build a fort to achieve their individual aims as mentioned in (a). However, one may wish to note that Singapores waters may not be that strategic after all. In 1613, Aceh successfully attacked Batu Sawar as she was upset about the signing of the peace treaty between Johor Sultanate and Portuguese, uncovering the vulnerable position of Singapore waters, rendering it no longer strategic. Moreover, when Melaka Straits lost its importance to Sunda Straits in the late 17th century, Singapore was neglected and declined over the 18th century. Its waters were no longer contested and the issue on it being strategic or not became irrelevant. A village of Orang Lauts and Malays, not being much of a deal, were all that were left in Singapore. Melaka Straits was filled with pirates and Singapore, lying on the Straits, was hence seen as a sleepy fishing village by the British when they landed in the 19th century. (2) does not take into account these happenings, thus it is flawed in describing Singapores history. In conclusion, (1) best describes Singapore history as it accommodates the period when Singapore was (3), when trade was active though declining, the period when it was considered strategic and its waters contested by the Dutch and Portuguese, up to the period when British founded Singapore as a sleepy fishing village due to the decline of Melaka Straits. (2) was unsuitable as mentioned above, and (3) seems to be an understatement as Singapore was more than just part of the Johor Sultanate.

Miniaturization Of Computing Technology Information Technology Essay

Miniaturization Of Computing Technology Information Technology Essay The revolution of electronic miniaturization began during World War II and is continuing to change the world till now. Miniaturization of computer technology has been the source of a seemingly endless battle between technology giants over the world. The market has become so competitive that the companies that develop microprocessors are constantly working towards erecting a smaller microchip than that of their competitor, and as a result, computers become obsolete almost as soon as they are put out on the market. The concept that underlies technological miniaturization is the smaller the better; smaller is faster, smaller is cheaper, smaller is more profitable. It is not just companies that profit from miniaturization advances, but entire nations reap rewards through the capitalization of new developments. Devices such as personal computers, cellular telephones, portable radios, and camcorders have created massive markets through miniaturization, and brought billions of dollars to th e countries where they were designed and built. In the 21st century, almost every electronic device has a computer chip inside. The goal of miniaturization is to make these devices smaller and more powerful, and thus made available everywhere. It has been said, however, that the time for continued miniaturization is limited the smaller the computer chip gets, the more difficult it becomes to shrink the components that fit on the chip. Devices made of semiconductors, notably silicon, are essential components of most electronic circuits. A process of lithography is used to create circuitry layered over a silicon substrate. A transistor is a semiconductor device with three connections capable of amplification in addition to rectification. Miniaturization entails increasing the number of transistors that can hold on a single chip, while shrinking the size of the chip. As the surface area of a chip decreases, the task of designing newer and faster circuit designs becomes more difficult, as there is less room left for the components that make the computer run faster and store more data. Gordon E. Moore introduced the concept known as Moores law in 1965, and it has been used in the semiconductor industry to guide long-term planning and development. The law predicts a long-term trend in which the number of transistors inexpensively places on an integrated circuit would double approximately every two years. His original statement appeared in his publication Cramming more components onto integrated circuits, Electronics Magazine 19th April 1965: The complexity for minimum component costs has increased at a rate of roughly a factor of two per yearà ¢Ã¢â€š ¬Ã‚ ¦Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years. That means by 1975, the number of components per integrated circuit for a minimum cost will be 65,000. I believe that such a large circuit can be built on a single wafer (Appendix 1) The original statement made reference to one year, but was later altered to two years. Moores law describes a driving force of technological change in the late 20th and early 21st centuries. The development and capabilities of several digital devices are linked to Moores law. Some of these include processing speed, memory capacity, and sensors. These devises are still improving at an exponential rate and have dramatically increased the usefulness of digital electronics in every segment of the world economy. One such segment is that of Information and Communication Technologies (ICTs). This type of technology allows users to participate in a rapidly changing world in which work and other activities are increasingly transformed by access to varied and developing technologies. ICTs impact on several areas of the economy, including productivity and innovation, as well as advances in science and technology. They are the leading factor in improving innovation and creativity, and as such, a great portion of the productivity gains in the economy are due to the impact of ICTs on products and services. In science and technology, they transform the way researchers conduct their research. Owing to increasing economic and social demands, technology must be brought closer to people and organizational needs. This entails making technology functional and simple to use, affordable and available, as well as meeting new preferences and needs. This demand calls for the proliferation of miniaturization whic h results in the emergence of a new wave of technologies. The Benefits and Challenges of Miniaturization Miniaturization is one of the fastest changing megatrends. Although it can be a great benefit for society, it also has its downsides. The challenges include cost-expensive, data inaccuracy, software unreliability, information overload and may result in: Invasion of Privacy and Identity Theft On the side of problems, one of the biggest growing crimes in America is caused by the affects of miniaturization. Invasion of personal privacy and identity theft are two very dangerous crimes that can not only embarrass you, but can also cause financial problems as well. A report composed by the news organization PRWeb states that 10 million consumers in the US become identity theft victims every year and those people spend a countless amount of time and money to correct these attacks. Not all 10 million are caused by miniaturization related electronics, but with the advancement in technology, miniaturization has greatly helped to increase the number of identity theft victims. Miniaturization plays a role in this crime because it has created the technology of miniature spy cams which aid voyeurism. Voyeurism is a practice in which an individual derives sexual pleasure from observing other people  [1]  . Some forms of voyeurism are legal, but if the person being viewed is unaware of the action, then it is illegal and considered an invasion of privacy. Loss of Electronic Devices Another problem with the trend of miniaturization, due to computerized electronics to become extremely more portable, is the increased ability to lose your electronic devices or have them stolen. As stated in the Apple patent, Current portable electronic devices such as laptop computers, hand-held devices such as cellular telephones and personal media devices, such as the Ipod from Apple Computer, and even devices such as compact disc players, are sufficiently compact and lightweight as to make them easily movable. Unfortunately, such ease of transport also implies ease of theft. While the rightful owner of a portable electronic device may conveniently transport it almost anywhere, so can a thief. (MacNN.com: Apple Patent,2007) Hearing Loss A third problem with miniaturization is the growth in use of portable MP3 players. These players have caused physiological damage because of the extended use of the ear buds and playing the players music extremely loud  [2]  . Noise-induced hearing loss involves individuals losing the ability to hear higher frequencies, evidenced at times by mild ear-ringing or trouble following conversations in noisy situations  [3]  . This hearing loss is directly related to the use of the MP3 players. What are some of the devices that have been impacted by miniaturization? There are multiple examples that reflect miniaturization, but perhaps the most well known miniaturized device is the cellular phone. The theory of mobile telephones was born in the early 1900s in the United Kingdom and the United States.   They were born out of research on mobile car phones, and calculated out that by limiting the range of transmitters, they could recycle the same radio frequencies. This allowed them to theorize the possibility that with this technology, many users would be able to share the same network. They were unable to put a production system together to prove this theory, due to the limit of available technology. In the early 1970s, ATT and Bell Labs proposed the first commercial cellular, mobile phone network.   The proposal was for a cellular network,  which was to consist of many small broadcast towers, covering a small area (termed a cell), a few miles in radius.   As the mobile phone moved across this network, the call would be passed on from towe r to tower. The first fully automatic, first generation cellular network (1G), was developed by Nordic Mobile Telephone in 1981.   1G was still based on analog radio signals. The advent of Second generation (2G) was in 1991.   High speed, third generation (3G) cellular networks became a reality when the Japanese company NTT DoCoMo rolled out its commercial WCDMA network. In 1986 cost between $2,500 to $3,500 and weighed just under 3 pounds (Appendix 2). Today, they are razor thin, weighing between 4 and 6 ounces and can cost from JMD$1,000 to JMD$60,000. Some of the most prominent include Nokia  and  Motorola. Other examples are the iPod Nano, Motorola Razor V3 and Dell Inspirion 700m. Ipod Nano The Ipod Nano, manufactured by Apple Computer, Incorporated, is a digital compression music player that delivers up to 1,000 songs. It features a very slim and compact design with dimensions of only 3.5 x 1.6 x 0.27 inches and 1.5 ounces and supports a colour LCD screen, the Apple Click Wheel, plays continuously for 14 hours, and holds other information besides music files. It also contains 2 gigabytes of memory that holds 500 songs. The Ipod Nano is able to be used for many purposes when you are unable to use a CD player or even for replacing a CD player. A few examples are exercising, going on vacations, among others. Also in recent news, Apple released a new form of miniaturization with the Ipod Video. This device will replace the older Ipods and will be able to support not only playing songs, but also displaying video on a two and a half inch screen (Appendix 2.1). Moto Razr V3 The next example of miniaturization is the Moto Razr V3, which is made by the Motorola Corporation. The features of the Razr V3 include ring tone downloads, calculator and currency converter, date and clock, alarm clock, calendar, instant messaging, text messaging, video games, photo camera, and video clip downloads. The Moto Razr V3 supports all this while still only weighing 3.35 ounces and having dimensions of 3.86 x 2.08 x 0.54 inches. The applications of this phone basically compare to those of a palm pilot. By having a phone with this power, anyone will be able to keep a strict control on their life (Appendix 2.2) Dell Inspiron 700m The final example is the Dell Inspiron 700m notebook, made by Dell Incorporated. It is the slimmest and lightest of all of Dells laptops being 4.1 pounds and 1.5 inches thick. Other features on this laptop include an Intel Pentium M Processor, Windows XP, a minimum of 256 megabytes of RAM, 12.1 inch screen, a hard drive with 40, 60, or 80 gigabytes, and an ethernet card for internet access. This laptops applications are very broad and diverse and can be used for meeting other people through the internet, doing business, recreational purposes like watching DVDs, burning DVDs, listening to music, playing computer games, or  by applying this computer to almost any aspect of a persons life (Appendix 2.3) Convergence Traditionally, communications media were separate and their services were distinct. Broadcasting, voice telephony and on-line computer services were different and operated on different platforms: television and radio machines, telephones and computers. Convergence is the combination of all these into one operating platform. It is the merger of telecom, data processing and imaging technologies. This convergence is incubating a new era of multimedia, in which voice, data and images are combined to provide services to the users. Traditional convergence is noted in the combination of the personal computer and the internet technology. This combination provides a convergence of data processing, images and audio services. Convergence makes it possible for one element to provide multi-service. An illustrated example of this is in the mobile phone, which was initially designed for voice communications. These days cell phones offer more functions: They offer print and text media as in the Short Message Service (SMS); they provide reception links to radio stations and access to broadcast information, they provide links to access the web, they capture, send and receive pictures and so forth. New generation of mobile phones are designed to capture video images.This had led to the death of many traditional devices like the Personal Digital Assistant and the proliferation of miniaturized devices. Miniaturization and the Digital Divide In the early 1990s, when someone referred to the digital divide they were really making reference to gaps in society between individuals who owned and had access to computers and those who had not. As the term evolved it adopted new meanings, it came to refer to the gaps between people with effective access to digital and information technology and those with very limited or no access at all  [4]  as well as refer to the inequalities between groups of people in their ability to use information technology fully. It also speaks to the imbalances in resources and skills needed to manipulate information on the internet. Therefore, the term digital divide is really two folds, it relates to the imbalances created by the inability to physically access technology and the unequal acquisition of skill attained with the constant use of said technology. Due to this the term is often interchangeably used with the knowledge divide, as it is proposed that if there is little to no access to the vast amount of information provided via the internet and technology individuals will be deficient in the attainment of knowledge supplied via this source. The four major components that contribute to the digital divide, as discussed by Bharat Mehra (2004, Digital Divide, Wikipedia, the free encyclopedia) are socio economic status, income, educational level, and racing among other factors associated with technological attainment. These are all major issues that affect society on a whole on a social level. The global divide on the other hand, refers to the same concept but in relation to countries as oppose to individuals. It really refers to differences to technology accessibility between Countries or the whole world. Miniaturization of technology in its truest form, if utilized properly will make an attempt to drastically reduce the gap in society that has significantly helped to perpetuate this problem. The continuous miniaturization of technology will among other things make technology more accessible to everyone. This is due to the fact that as technology gets smaller, it uses less resource to manufacture them and hence cause a reduction in the production cost. This in turn, causes a reduction in the selling cost, making it cheaper and more accessible to everyone. Technology is no longer only for the wealthy or the wealthiest countries, nor is it a means by which the rich can showcase their wealth. Now that miniaturization has made it accessible to almost everyone, the digital divide as it pertains to access to technology is noticeably dwindling. Projects like One Laptop per Child offer a partial solution to the global digital divide; these projects tend to rely heavily upon open standards and free open source software. The OLPC XO-1 is an inexpensive laptop computer designed and intended to be distributed to children in developing countries around the world, to provide them with access to knowledge (Appendix 3). Organizations such as Geekcorps, EduVision and Inveneo also help to overcome the digital divide with the use of now miniaturized technology. They often do so through the use of education systems that draws on information technology. The technology they employ often includes low-cost laptops, subnotebooks, handhelds (eg Simputer, E-slate), tablet PCs, Mini-ITX PCs, and low-cost WiFi-extending technology as cantennas and WokFis. In addition, other information technology material usable in the classroom can also be made diy to lower expenses, including projectors. Surely one can see, by these examples, where the continuous miniaturization of technology is playing some part in diminishing the global digital divide. These and other continuous efforts are reducing the digital global divide in developing countries owing mainly to miniaturization. As time progresses individuals will find new and innovative ways to make technology smaller and smaller and hence making them more accessible to the general public and more importantly, to developing nations. The Future of Miniaturization The future of miniaturization is uncertain as there have been many different projections as to where designer and creators want it to go. Some believe that the idea is to get more transistors on a single chip. Increasing the number of transistors ultimately leads to more power in the computer, cell phone, handheld PDA and other electronic devices that have a computer chip inside. In our times just about every electronic device has a computer chip inside. The pursuit to make these devices more powerful, and thus effectively independent of a constant power source, is the focus for miniaturization in computer technology. Ultimately the goal is to have computers everywhere by making components smaller and more powerful. However, what we do know is that technology will get smaller and smaller until they are almost microscopic. Technology created in the future will all have a few similar characteristics, they will be smaller, lightweight, durable, reliable, tamper-proof, and consume very l ittle power. However with these advances comes a certain level of concern. One of the biggest and most common concerns in making computer technology smaller is the availability of the Internet. As computers are miniaturized down to the subatomic level, computers could literally be floating around in the air. By building computers on the subatomic level, the laws of physics do not apply as we know them. This allows for greater flexibility in computer connectivity, and may eventually make wiring computers together obsolete. While this and other concerns are valid, with the continuous creation and evolution of technology, they will soon no longer be relevant concerns.

Federalists vs. Anti-Federalists :: essays research papers

Federalists vs. Anti-Federalists From 1787-1790 the development of the American Constitution was a battle between two opposing political philosophies. America’s best political minds gathered in Philadelphia and other cities in the Northeast in order to find common ground in a governmental structure. The Federalists and the Anti-Federalists had both some political thoughts that agreed as well as some political thoughts that disagreed. However, both parties would compromise and ultimately come together. The Federalist Party, led by James Madison, was in favor of the newly formed Constitution. One of the main objects of the federal constitution is to secure the union and in addition include any other states that would arise as a part of the union. The federal constitution would also set its aim on improving the infrastructure of the union. This would include improvements on roads, accommodations for travelers, and interior navigation. Another consideration for the Federalist Constitution would be in regards to the safety of each individual state. They believed that each state should find an inducement to make some sacrifices for the sake of the general protection. The Anti-Federalist Party, led by Patrick Henry, objected to the constitution. They objected to it for a few basic reasons. Mostly the Anti-Federalists thought that the Constitution created too strong a central government. They felt that the Constitution did not create a Federal government, but a single national government. They were afraid that the power of the states would be lost and that the people would lose their individual rights because a few individuals would take over. They proposed a â€Å"Bill of Rights†, to make sure the citizens were protected by the law. They believed that no Bill of Rights would be equal to no check on our government for the people.

The Immeasurable Value of Science Essay -- Science, Scientific Theorie

Few people would disagree that the study of science is a vital part of the world we live in. It is when you take a step back and assess why is true that you are able to appreciate science for it’s many contributions to our daily lives. When thinking of science, people commonly think of some high school or college laboratories filled with students working with Bunsen burners and beakers bubbling with colored liquids, but science goes far beyond the walls of these educational facilities. Science can be found not only in laboratories and classrooms, but also outside in a meadow, or in the kitchen of a restaurant, or even in the night sky. From pharmaceutical labs that create medication to helps people fight diseases, to a seventh grade class excited to launch their hand-crafted rockets, to understanding that scientific theories are used to better describe natural occurrences; science is everywhere, and is utilized in all different types of mediums. It is important to remember t hat science plays a crucial role in society and each person individually because constantly effecting us all in so many extraordinary ways. Science is subject in which many people view as a study of creating, building, and experimenting with things to discover and form results. One aspect of science is about creating objects and building knowledge to find results and products that expand on current ideas and devices. A popular television show on the Discovery Science channel, â€Å"How It’s Made,† offers viewer a glimpse into the processes of how objects from our everyday lives are created and assembled. In one episode, the show follows the process from which plastic materials are melted, dyed, molded and then run through a series of machines to produce thousan... ...rough various examples of science thought of, explored, and applied in every day life, it is clear that science holds extreme value for individuals and society. Without science we would be drudgingly stuck with the same thoughts, ideas and products because we were uninterested in thinking rationally about how to improve upon these existing things to create and inspire better. Without science we would not be able to have an intellectual understanding and enjoyment of many processes and occurrences in our every day lives. Of course, without science, the white paper you read from, the shoes you walk in, and the car you drive would not exist. It is important to know that science plays a vital part in all of our lives, every day, at any given moment, and the value of science to the individual and society is immeasurable with all of these many things taken into account.
