Summary and response - Essay Example le media such as tv, books, computers, mp3 players and video games by children in the United States are cited, and questions are raised regarding the proper response to such emerging issues. A short questionnaire is supplied, and readers are invited to test themselves against these questions to see whether or not they suffer from internet addiction. The authors conclude with some advice regarding early interventions and treatment and there is a reference list with useful sources for further reading. This is an informative article which explains the relation between internet usage and other types of behavior which can be quite normal when carried out in moderation, but become pathological when taken to an extreme. It gives good advice on a rather simplistic level and this makes it suitable general public readership. The article describes what internet addiction is, how it can affect people, and what to do about it, but there is no consideration of the causes of this problem or any statistic on trends across countries and through time. The authors asked the question whether internet addiction is an epidemic or a fad, but they did not fully answer this question. They admit that it is a problem â€Å"for at least as subset of internet users† (Jaffe and Uhls, 2011, p.1) but it is hard to tell how serious or widespread this problem is. I would like to have seen a deeper analysis of the reasons why people are so drawn to the internet and what the bigger implications are for Ame rican lifestyle and culture now and in the future.

Rosetta Stone Essay Example | Topics and Well Written Essays - 1250 words

Rosetta Stone - Essay Example The Rosetta Stone contains a priestly decree in honour of Ptolemy V which was set up in a major temple. (Wilson, 2004, p. 31) It is said that European archaeology in Egypt began during the French expedition when French soldiers accidentally discovered the Rosetta Stone, however the greatest contribution to the stone was made by Jean-Francis Champollion who after twenty-three years of struggle and work out on studying hieroglyphs was able to uncover the secrets behind 'Rosetta stone' in 1822. Champollion was the one who is held responsible for opening the doors to modern Egyptology. According to Reid (2002) "The French expedition is solely responsible for finding Rosetta Stone as without their expedition there would have been no description of ancient Egypt. It is the stone who brought before us the decipherment of hieroglyphics, otherwise it would have been delayed and, until the decipherment, most pharaoh history would have remained missing. Therefore, the onus is on the stone who revealed modern Egypt and Egyptology". (Reid, 2002, p. 14) The French soldiers after discovering the Rosetta Stone while digging fortifications, left Egypt on the threshold of Anglo-French geopolitical rivalry. This situation fatally weakened the Mamluks (slave soldiers), thereby paving the way for Muhammad Ali. In this context the stone was responsible for a major change occurrence economically, politically and culturally through Muhammad Ali's reign. In archaeology, the French expedition and Muhammad Ali's reign ushered in a new era where the emphasis was given to decipher 'Rosetta Stone'. However the stone paved the way to the decipherment of hieroglyphics and the birth of modern Egyptology, and the Description advanced the documentation of pharaoh art, architecture, and topography. (Reid, 2002, p. 32) Most notably, the 1799 discovery of the Rosetta Stone, a trebly-inscribed stone fragment unearthed by his army during Napoleon's Egyptian campaigns, presented the general as the heroic person likely to unlock the mysteries of ancient Egypt by translating hieroglyphs. Linguistic Significance: Rosetta stone is actually the surviving fragment of granite is inscribed with the decree to guarantee lands and endowments to the temples of Egypt. What is carved on the stone is called the Ptolemaic decrees, written in praise of the then pharaoh. The written text on the Rosetta Stone revealed that the same text on the stone is written in three different languages: Greek (for the ruling administration of the day), Egyptian hieroglyphs (for the gods), and Egyptian Demotic (for a common man). The range of languages reflects the strata of Egyptian society at this time and the lines of communication. Even though the Rosetta Stone was handed over to the British as part of the spoils of the Napoleonic War, the texts had by then been copied and were later sent all over the world. The process of decipherment required several stages as each of the principles behind the script was discovered. With hindsight, it seems as if it were a step-by-step progression, but in fact often one person would have a good idea, but would continue to use other incorrect assumptions at the same time. So, the final triumph came from deciding which of the many permutations

Put a Girl in it Essay -- Sociology, Human Companionship

Put a Girl in it Human companionship is one of the most basic needs of humans that can be seen in the Creation story. It is tricky for any human to find the perfect companion, especially if one is one of a kind. In Mary Shelly’s Frankenstein two characters exemplify this need Dr. Victor Frankenstein and The Creature. They are in search of the same thing companionship, and they go to great lengths to try to achieve it from the traditional to scientific discoveries. The classic theme of perversion of family is a major component in Frankenstein. Dr. Frankenstein comes from a good family and in his adult life he longing for a loving companion is mainly found in the pursuit of the Creature and Elizabeth. The development for the need for the Creature starts when he falls in love with knowledge and is furthered when he leaves to study. In his childhood he finds â€Å"Natural philosophy is the genius that has regulated my fate; I desire, therefore, in this narration, to state those facts which led to my predilection for that science† (Shelley 36). This passion develops into his obsession in his adult life when he gains more accesses to scientific knowledge and new technology. Then it climaxes with start of the creation of the Creature because his accesses to bodies and tools. Victor sees his progression, â€Å"I read with ardour those works, so full of genius and discrimination†¦ it easily conceived that my progress was rapid† (48 ). His description of the creation makes it seem like he is mothering a child into birth. He distorts the sanctity of childbirth by creating a human in a lab. This also makes him the mother and father of the Creature. He realizes the immense power he holds, â€Å"When I found so astonishing a power placed within my han... ...led â€Å"You must create a female for me with whom can live in the interchange of those sympathies necessary for being† (145). Creature seems to be devout of all humanity except the meager scrapes of which it was made, but it still appears to have the deep emotional needs of all humans. Having to fight off the world he seems callus. The need for a female is so overpowering, it forsakes everything to just have a companion to love. The Creature is seen as a human. It really shares all the properties that humans have but it is ostracized because of his appearance. The basic need of compassion and a companion is shared by all humans.

Paper VS Electronic Media Essay

Paper vs. Electronic Media: Work Efficiency and Environmental Impact Hirohito Shibata; Fuji Xerox Co., Ltd., 6-1 Minatomirai, Nishi-ku, Yokohama, Kanagawa, 220-8668, Japan Abstract Table 1. CO2 emissions per unit quantity for each product This presentation quantitatively compares paper and  electronic media from the perspectives of CO2 emissions and work efficiency. Should we reject paper out of hand based on  environmental considerations? Can electronic reading devices replace paper books for leisure and work? I discuss these issues based on various analyses and experiments. Product Introduction Although the paperless office has been repeatedly dismissed  as a myth [1], since 2008, the consumption of office paper in Japan has actually declined. With the advent of electronic reading devices such as Apple’s iPad and the Amazon Kindle, the idea of the paperless office is back in the spotlight. How seriously should we take this second coming of the paperless office? What will happen to paper? What are the relative merits of paper and electronic media? My colleagues and I at Fuji Xerox are currently at work on a research project that seeks to answer these questions. This presentation consists of two parts. The first part  compares paper to electronic media from an environmental  perspective, comparing CO2 emissions generated by paper vs. electronic media (e.g., computer displays, projectors) for reading or reference work. I also compare work efficiency for paper vs. computer displays. The second part compares paper books and  electronic reading devices (e.g., iPad, Kindle) and discusses whether  electronic books might actually take the place of paper books. This paper is a brief report and addresses only the results of these specific analyses and experiments. Standard PC Specifications Desktop High-Performance Desktop PC 17-inch Display 19-inch Display Notebook PC Projector Printer CPU: Intel Core Memory: Less than 4GB CPU: Intel Core Memory: More than 4GB TFT TFT Resolution: More than 1290Ãâ€"800 Electro Photo A3 Printers CO2 emissions per unit quantity 49.60 g/hour 98.42 g/hour 23.36 g/hour 26.34 g/hour 27.59 g/hour 163.58 g/hour 2.58 g/sheet Environmental Impact: Paper vs. Computer Displays CO2 Emissions Table 1 presents CO2 emissions per unit quantity for each  product. This data is based on figures for life cycle CO2 emissions for each product obtained in November 2010 from the website of the Japan Environmental Management Association for Industry [2]. Figure 1 compares CO2 emissions associated with each medium when reading an eight-page document. Reading from  paper generates CO2 emissions only at the time the document is printed. In this case, the hours spent reading do not affect CO2 emissions. On the other hand, when we read from displays, CO2 emissions increase in proportion to the time spent reading. For extended reading sessions, CO2 emissions tend to be lower for paper; for reading many short documents, CO2 emissions tend to be lower with computer displays. NIP 27 and Digital Fabrication 2011 Figure 1. CO2 emissions associated with reading Figure 2 compares CO2 emissions for each medium for the case of a ten-page document shared in a meeting. If we deliver this document on paper, CO2 emissions increase in proportion to the number of individuals attending. If we use a projector and a single notebook PC, the number of participants doesn’t affect CO2 emissions. In general, if we are sharing documents for a large meeting, CO2 emissions are lower when we use  projectors than when we distribute on paper. When we share short documents in small groups of two or three, CO2 emissions tend to be lower when we distribute documents on paper. Technical Program and Proceedings 7 of key words in text when using paper and when using computer displays. Reading from paper was 6.8% faster than reading from displays. There was no significant difference between the media in the recognition test of key words. Paper allows faster reading without loss of understanding. Figure 2. CO2 emissions associated with meeting documents Work Efficiency The analyses of the previous section assume equal work efficiency for all media. However, efficiency may actually vary with different media. Lower work efficiency means longer  working hours, which in turn can mean higher CO2 emissions,  since elements of the workplace infrastructure (e.g., ventilation and lighting) need to run longer. I’ll describe three experiments that compare reading performance for each medium. The first experiment examines how different media affect  proofreading when the goal is to detect contextual errors. Figure 3 presents reading speed and percentage of errors detected when using paper vs. computer displays. Reading from paper was 11.9% faster than reading from the displays. There was no significant difference between media in percentage of errors detected. Figure 3. Reading speed and the percentage of errors detected in proofreading to detect contextual errors (N = 20) Figure 4. Reading speed and scores for a recognition test of key words when reading with frequent page turning (N = 18) The third experiment involved cross-reference reading for  multiple documents [4]. Figure 5 compares reading speed and  percentage of errors detected when using paper vs. computer  displays. Reading from the paper was 23.2% faster than reading from displays. Moreover, more errors were detected (a difference of 11.5%) with paper than with computer displays. In both speed and accuracy, paper was superior to displays in cross-reference reading. Figure 5. Reading speed and the percentage of errors detected in crossreference reading for multiple documents (N = 24) The second experiment looked at reading when the task  required frequent switching back and forth between pages [3]. Figure 4 compares reading speed and scores for a recognition test 8  ©2011 Society for Imaging Science and Technology Discussion Comparisons of CO2 emissions from paper and electronic  media indicate that the nature of a task determines which is more eco-friendly. The three experiments here point to the superiority of paper for different reading tasks: proofreading, reading with frequent movement back and forth between pages, and crossreference reading for multiple documents. Clearly, this is hardly an exhaustive listing of all tasks that involve reading. Still, the results suggest paperless work is not always the most eco-friendly work style. Paper should not be rejected out of hand on environmental grounds. Rather, we should select paper or electronic media depending on the specific task. Figure 7 compares task completion times and accuracy  (percentage of correct answers) for each medium in an experiment involving  scanning a manual to find answers. Subjects performed this task 38.6% faster with the paper book than with the iPad and 60.2% faster than with the Kindle. Of the five media, paper books were fastest for scanning text for answers. Work Efficiency: Paper vs. Electronic Reading Devices Reading fiction As a typical example of reading for leisure, I evaluated  electronic reading devices such as iPad and Kindle for reading fiction. Figure 6 shows reading speed with a paper book, an iPad, a Kindle, and a notebook PC. For reading that did not involve  moving from one page to the next, I found no significant  difference in reading speed among the four media. For reading that required page turns, I found that reading from the iPad was as fast as reading from paper books, but that reading from the Kindle was slower than reading from paper books. This suggests that the iPad is just as suited as paper books for tasks like reading fiction. Figure 7. Completion time and percentage of correct answers when scanning text to locate answers to questions (N = 20) Discussion Figure 6. Reading speed: Paper book vs. electronic media (N = 26) For reading fiction, our experiment showed iPads and paper  books offered equal reading speed for reading with and without page turns. This suggests that the current generation of electronic reading devices is perfectly suitable for reading for leisure, at least from the perspective of efficiency. Clearly, other factors such as cost, weight, and design will also determine whether such devices gain widespread acceptance for this purpose. Paper books proved the fastest of all five media in the  experiment involving scanning text to find answers to questions, the reading task ranked as the second most common in the study by Adler et al. Moreover, as discussed above, the current  generation of electronic reading devices remains poorly suited for cross-reference reading, the reading task ranked as the most common. These results suggest that the electronic reading devices currently available do not adequately cover the wide range of reading tasks required for knowledge work. Reading to answer questions Trademarks Adler et al. [5] observed various work-related reading tasks in actual work situations and assigned each instance to one of ten categories. Among the most frequently observed tasks was crossreference reading using multiple documents. Clearly, the current generation of electronic reading devices does not permit crossreference reading. These devices do not allow us to view multiple documents at the same time, and their form factors are too cumbersome to overlap or otherwise move frequently. For this reason, I evaluated these devices for the second-most common task in the study by Adler et al.: scanning text to answer questions.

Who Invented the Intel 1103 DRAM Chip

The newly formed Intel company publicly released the 1103, the first DRAM – dynamic random access memory – chip in 1970.  It was the bestselling semiconductor memory chip in the world by 1972, defeating magnetic core type memory.  The first commercially available computer using the 1103 was the HP 9800 series. Core Memory   Jay Forrester invented core memory in 1949, and it became the dominant form of computer memory in the 1950s. It remained in use until the late 1970s. According to a public lecture given by Philip Machanick at the University of the Witwatersrand: A magnetic material can have its magnetization altered by an electric field. If the field isnt strong enough, the magnetism is unchanged. This principle makes it possible to change a single piece of magnetic material – a small doughnut called a core – wired into a grid, by passing half the current needed to change it through two wires that only intersect at that core. The One-Transistor DRAM Dr. Robert H. Dennard, a Fellow at the IBM Thomas J. Watson Research Center, created the one-transistor DRAM in 1966. Dennard and his team were working on early field-effect transistors and integrated circuits. Memory chips drew his attention when he saw another teams research with thin-film magnetic memory. Dennard claims he went home and got the basic ideas for the creation of DRAM within a few hours.  He worked on his ideas for a simpler memory cell that used only a single transistor and a small capacitor. IBM and Dennard were granted a patent for DRAM in 1968. Random Access Memory   RAM stands for random access memory – memory that can be accessed or written to randomly so any  byte or piece of memory can be used without accessing the other bytes or pieces of memory. There were two basic types of RAM at the time: dynamic RAM (DRAM) and static RAM (SRAM). DRAM must be refreshed thousands of times per second. SRAM is faster because it does not have to be refreshed.    Both types of RAM are volatile – they lose their contents when power is turned off. Fairchild Corporation invented the first 256-k SRAM chip in 1970. Recently, several new types of RAM chips have been designed. John Reed and the Intel 1103 Team   John Reed, now head of The Reed Company, was once part of the Intel 1103 team. Reed offered the following memories on the development of the Intel 1103: â€Å"The invention? In those days, Intel – or few others, for that matter – were  focusing on getting patents or achieving inventions. They were desperate to get new products to market and to begin reaping the profits. So let me tell you how the i1103 was born and raised.In approximately 1969, William Regitz of Honeywell canvassed the semiconductor companies of the U.S. looking for someone to share in the development of a dynamic memory circuit based on a novel three-transistor cell which he – or one of his co-workers – had invented. This cell was a 1X, 2Y type laid out with a butted contact for connecting the pass transistor drain to the gate of the cells current switch.  Regitz talked to many companies, but Intel got really excited about the possibilities here and decided to go ahead with a development program. Moreover, whereas Regitz had originally been proposing a 512-bit chip, Intel decided that 1,024 bits would be feasible. And so the program began. Joel Karp of Intel was the circuit designer and he worked closely with Regitz throughout the program. It culminated in actual working units, and a paper was given on this device, the i1102, at the 1970 ISSCC conference in Philadelphia.  Intel learned several lessons from the i1102, namely:1.  Ã‚     DRAM cells needed substrate bias. This spawned the 18-pin DIP package.2.  Ã‚     The butting contact was a tough technological problem to solve and yields were low.3.  Ã‚     The IVG multi-level cell strobe signal made necessary by the 1X, 2Y cell circuitry caused the devices to have very small operating margins.Although they continued to develop the i1102, there was a need to look at other cell techniques. Ted Hoff had earlier proposed all possible ways of wiring up three transistors in a DRAM cell, and somebody took a closer look at the 2X, 2Y cell at this time. I think it may have been Karp and/or Leslie Vadasz – I hadnt come to Intel yet. The idea of using a buried contact was applied, probably by process guru Tom Rowe, and this cell became more and more attractive. It could potentially do away with both the butting contact issue and the aforementioned multi-level signal requirement and yield a smaller cell to boot!  So Vadasz and Karp sketched out a schematic of an i1102 alternative on the sly, because this wasnt exactly a popular decision with Honeywell. They assigned the job of designing the chip to Bob Abbott sometime before I came on the scene in June 1970. He initiated the design and had it laid out. I took over the project after initial 200X masks had been shot from the original mylar layouts. It was my job to evolve the product from there, which was no small task in itself.Its hard to make a long story short, but the first silicon chips of the i1103 were practically non-functional until it was discovered that the overlap between the PRECH clock and the CENABLE clock – the famous Tov parameter – was very critic al due to our lack of understanding of internal cell dynamics. This discovery was made by test engineer George Staudacher. Nevertheless, understanding this weakness, I characterized the devices on hand and we drew up a data sheet.  Because of the low yields we were seeing due to the Tov problem, Vadasz and I recommended to Intel management that the product wasnt ready for market. But Bob Graham, then Intel Marketing V.P., thought otherwise. He pushed for an early introduction – over our dead bodies, so to speak.  The Intel i1103 came to market in October of 1970. Demand was strong after the product introduction, and it was my job to evolve the design for better yield. I did this in stages, making improvements at every new mask generation until the E revision of the masks, at which point the i1103 was yielding well and performing well. This early work of mine established a couple of things:1.  Ã‚     Based on my analysis of four runs of devices, the refresh time was se t at two milliseconds. Binary multiples of that initial characterization are still the standard to this day.2.  Ã‚     I was probably the first designer to use Si-gate transistors as bootstrap capacitors. My evolving mask sets had several of these to improve performance and margins.And thats about all I can say about the Intel 1103s invention. I will say that getting inventions was just not a value among us circuit designers of those days. I am personally named on 14 memory-related patents, but in those days, Im sure I invented many more techniques in the course of getting a circuit developed and out to market without stopping to make any disclosures. The fact that Intel itself wasnt concerned about patents until too late is evidenced in my own case by the four or five patents I was awarded, applied for and assigned to two years after I left the company at the end of 1971! Look at one of them, and youll see me listed as an Intel employee!

Attention Deficit / Hyperactivity Disorder Essay - 1244 Words

Attention-deficit/hyperactivity disorder, also known as ADHD, is one of the most prevalent childhood and adolescence disorder. ADHD world prevalence rates is around 5% and â€Å"range from 1% to 20% among school-age children (Sciotto, †¦2016, p. 35). There is a variability in prevalence rates across countries, which has led to researchers to question whether ADHD diagnosis reflects the norms and biases of western cultures. Even though the diagnosis are thought to reflect western cultures and norms, it has been difficult to agree professionally on what ADHD is, what should be done about it, and how it should be approached (Timimi, S. Taylor, E., 2003, p. 8). There is a lack of specific cognitive, metabolic, or neurological procedures and medical tests for ADHD. In addition to this lack, considering the different cultures adds to the difficulty of accurately identifying ADHD. It is, however, important to realize that culture plays an important role in identifying, diagnosing, an d treating ADHD. Variations in diagnostic practices, medication treatment prevalence, school system policies, and cultural attitudes influences the availability to services for ADHD (Scuitto et al., 2016, p.35).

Astrophysics is the branch of astronomy that employs the principles of physics and chemistry to ascertain the nature of the heavenly bodies, rather than their positions or motions in space. A few of the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. The study of our very own Sun has a special place in observational astrophysics. Due to the tremendous distance of all other stars, the Sun can be observed in a kind of detail unparalleled by any other star. Our understanding of our own Sun serves as a guide to our understanding of other stars. Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, astrophysicists typically apply many disciplines of physics, including mechanics, electromagnetism, statistical mechanics, thermodynamics, quan tum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics. Modern astronomical research often involves a substantial amount of work in the realms of theoretical and observational physics. Some areas of study for astrophysicists include their attempts to determine: the properties of dark matter, dark energy, and black holes, whether or not time travel is possible, if wormholes can form, or the multiverse exists, and also the origin and ultimateShow MoreRelatedMy College Major Will Be Astronomy1759 Words   |  8 Pageswill be astronomy. Astronomy is the study of the universe beyond the Earth, such as the stars, planets, and other celestial objects. Astronomy pushes the limits of our technology, which leads to the development of new instruments and processes processes. Astronomy is considered to be an important because of the â€Å"space age†, where many new developments in technology and new ideas were introduced.

It’s hard to explain but OutSpace is the most fascinating thing to learn about. Everything from the stars at night to the possibility of having galactic neighbors puts me in complete awe. It’s just exciting to me and its impressive how vast and unexplored the universe is.

A question was brought up to Richard Quinn, a SETI Institute researcher with Ames Planetary Systems Branch, if Mars was a habitable environment? Based on what we know about life in extreme environments, interpretations of mission results indicate that we are currently exploring habitable ancient environments on Mars, and I believe that these are solidRead MoreThe Idea Of Black Holes1913 Words   |  8 PagesEinstein expanded his ideas to create a new sect of physics and ideas about how the world works. Einstein’s theory states that the law of physics are the same for all observers not in motion and acceleration and that the speed of light in a vacuum was indep endent of the motion. He worked with the ideas of space and time and proposed that same and time worked in a continuum called space-time. Space-time continuum creates an idea of how events that occur at the same time for one observer could occur at differentRead MoreForce9499 Words   |  38 PagesMaster Sheets Topics Available Year 7-8 General Science Disk Filename 01.Energy 02.Forces 03.Matter 04.Mixtures 05.Elements 06.Cells 07.Life 08.LifeSystems 09.Astronomy 10.Earth 11.Ecosystems Topic Name Energy Forces Solids, Liquids Gases Separating Mixtures Elements Compounds Living Cells Living Things Plant Animal Systems Astronomy The Earth Ecosystems Year 9-10 General Science Disk Filename 12.Waves 13.Motion 14.Electricity 15.Atoms 16.Reactions 17.DNA 18.Evolution 19.Health 20.UniverseRead MoreOrganisational Theory230255 Words   |  922 PagesOrganizational Theory takes you on a joyful ride through the developments of one of the great enigmas of our time – How should we understand the organization?
