Arguments Against Nuclear Weapons
Arguments Against Nuclear Weapons Nuclear weapons. Without a doubt, the deadliest form of weapon man has ever invented, capable of killing millions of people and annihilating entire cities. They are inhumane weapons that carry catastrophic effects when used which are present for many years after the explosion. Despite this, there are thousands of nuclear weapons in possession of several nations around the world. Even if these weapons of mass destruction were never actually used for the purpose of causing harm, their very existence still carries significant consequences. I firmly believe that the only way to bring an end to the needlessly harmful effects that such weapons carry is a ban on both their use and possession or at least a reduction in countries nuclear arsenal and in this essay I will be explaining why. Obviously, one of the main arguments against the possession and use of nuclear weapons is their devastating effect on both the people and the environment. So far, the only use of nuclear weapons for the purpose of warfare was the USAs use of atomic bombs in Japan during the events of World War 2. These bombs were relatively small compared to the weapons possessed by some nations today, but their use still had catastrophic effects. After the bomb ironically named Little Boy was dropped on Hiroshima, 5 square miles of the city was destroyed, 70,000 80,000 people were immediately and mercilessly killed by the blast. Others died either from the collapsing buildings or from the intense radiation exposure. The suffering did not end there, the increased radiation levels in the area caused a massive increase in the cancer occurrences in people and birth deformities. The environment was also inevitably affected; the radioactive fallout caused plants and wildlife to be affected. While this ma y seem bad, the technological advances in society today has spawned even more destructive and dangerous nuclear weapons that, if used would have effects far worse than what was seen during World War 2. In addition, some scientists hypothesise that a small scale nuclear war between India and Pakistan would result in megatons of black carbon being released into the atmosphere, causing what scientists call a Nuclear Winter. This would lead to global temperatures falling and we would receive 9% less rain every year. This would ultimately cause crop failure worldwide and an estimated 2 billion people would starve. Chemical reactions would also occur in the atmosphere which would thin the Earths ozone layer, which protects us from the suns ultraviolet rays. In a couple of years after the nuclear exchange, the ozone layer would be approximately 20 to 25 percent thinner. The decreased protection from UV radiation from the sun would lead to an increased occurrence of skin cancer in people and a further amount of crop failure. Furthermore, possessing and maintaining nuclear weapons is also very costly, the scientists have high salaries and the materials are expensive. The weapons need to be continuously maintained and money also needs to be spent on waste management. The UK spends an enormous  £2 billion each year on running and maintaining Trident (the UKs nuclear weapon arsenal). That is around the amount spent on the NHS each week. There are also discussions on whether the Trident submarines should be replaced. This would cost around  £100 billion. That is a massive amount of money which could be much better spent on essential services such as healthcare and education. This is especially important considering the financial crisis that the NHS is in which may force them to abandon free healthcare for the public unless they get more funding. Needless to say, this would have a very undesirable effect on the public. One of the most popular arguments for the possession of nuclear weapons is that they are very useful as deterrents and help to maintain peace between nations. In order for the idea of nuclear deterrence to be effective, we must assume that all nation leaders think the best interest of the people of their country. However, it is well known that some nations do not play by this very delicate ruleset. These include terrorist organisations. This is a gamble on millions of human lives that is not worth taking. Because most nuclear threats come from dictatorships and terrorist organisations instead of genuine governments, it would be morally wrong to cold-bloodedly kill tens of thousands of civilians because of the actions of a select few. There is also the risk of accidental firings because of mistakes, errors in calculations or moments of panic. The fact that just one single mistake or irrational decision can take the lives of millions of people is yet another reason why it is wrong for anyone to possess such weaponry. The possession of nuclear weapons also brings about the risk of loss or theft. With the growing nuclear arsenal of nations such as Russia, other nations may find it necessary to upgrade their nuclear arsenal to counteract the possible threat. An increased number of nuclear weapons means a greater risk of them being stolen, lost or even worse, detonated. This issue is becoming increasingly more important with the new president of the United States Donald Trump wanting his countrys nuclear arsenal to be above all else. This nuclear superiority the US desires will surely increase the tension between nations and amplify the risk of a nuclear attack or accident. In conclusion, the possession of nuclear weapons will continue to bring its vast array of disadvantages, whether that be the catastrophic effects that a nuclear weapon explosion could bring. Using valuable money that could be much better spent elsewhere such as in healthcare or education. Or by being the cause of many conflicts and suffering across the world. As long as nations possess nuclear weaponry, they will most likely be used again, either on purpose or by accident. The only way to prevent this would be for nuclear weapons to follow the same fate as chemical and biological weapons and receive a worldwide ban on both their possession and use.

Northern Californias Coastal Redwoods :: Essays Papers
Northern California's Coastal Redwoods ~A Brief Overview ~ "chain saw rising, whining out of a cut, falling thump of a log, limbed & bucked & loaded and where it spills over rocks as if another truck pulling back up the ridge, empty only there-- there was no hearing it only water and the rock where it turns the water singing the forest cut down and there only rock to hear it fall." GRAPH The average Redwood's life spans from around 800 to 1500 years. These anciet Redwoods were here when the dinosaurs roamed the earth, and 65 million years later we can now stroll through these living artifacts in coastal California. Typically people think that redwood forests are made up entirely of redwoods. But that isn't so--a healthy old-growth redwood forest is a mix of redwoods, deciduous trees, ferns, vines, flowers and wildlife. Giant redwoods are so tall, dense, and so crowded in the canopy, that some ground areas rarely see the sunlight, and little grows beneath these large giants. But whenever a tree does fall by Mother Nature or man, it leaves a gaping hole, that goes noticed. GRAPH Redwoods were named for the color of their bark and heartwood. These trees have a high resistance to fungus and diseases due to the high tanin content in the wood. The dense, fibrous bark has an even higher content, and acts as an insulator from periodic fires which have plagued the countryside for centuries. Though these trees are immense, they have delicate foliage. The needles are narrow and sharp-pointed, and combine to form feathery sprays. The cones are an inch long and typically contain fourteen to twenty-four seeds. The older trees offspring sprout form their parents' roots in order to take advantage of the established root system.

Possessing The Secret Of Joy: Four Men To Find A Cure :: essays research papers
Four Men to Find a Cure The four main men in Possessing the Secret of Joy have roles that contradict a stereotypical male; they are the cure to Tashi's happiness. Alice Walker gives Adam, Mzee, Pierre, and Benny roles that show a softer side to men. These four men are very different from each other but they do have some resemblance of each other. These men who were all very devotedly attached to Tashi took care of her and never gave up on her. Instead of deceiving and being indolent, these four men were very likeable. The men tend to symbolize and represent different aspects of Tashi's life. Tashi's husband Adam symbolized love. He was the only lover of Tashi that we read about. He cared for her and watched over her even when he did not have control over her. Adam may not have been loyal to Evelyn, but he loved her and took care of her. He knew the real Tashi that many people never saw. He was loyal to Tashi, but after the circumcision he would barely ever see her. He was more of a great friend than a good husband was. He lets her know that he loves her several times in the book. At their marriage he cuts the same lines in his face as Tashi had to represent the Olinkans. He goes with her to Mzee's house in Switzerland while she is cured. He also dreams about her and her livelihood, like when she used to say, "But what is it?" when she was happy. Adam, Olivia's brother, was daring at heart. He and Tashi used to go the fields to have sex that was considered very taboo. His mentors were Lisette and Pierre. He learned from them. He was in love with Lisette. Sh e was the contrast to Tashi. She was the opposite of her. Adam probably would have rather lived in France with her, but he stood by Tashi to give her love and affection. Adam was not a bad guy at all. He helped Tashi through the years and was always there whenever she needed somebody. It was unfair of him to be cheating on Tashi with Lisette, and Tashi resented him for that. He was always honest with Tashi though. Adam, like many of the other men in this book, was not a terrible person. He was good at heart.

The Meaning of Abstract Art Essays -- essays research papers
There are generally two types of paintings- representational and abstract. While representational painting portrays recognizable objects, abstract painting does not look like a particular object. Instead, abstract art is made up of designs, shapes and colors. (http://www.harley.com/art/abstract-art/ ) The meaning of abstract art is, in its most simplified form, art that relies on the emotions of the artist and the elements of design rather than exact representation. This broad definition allows artists almost unlimited freedom of expression. Some abstract artists create compositions that have no precedent in nature. Other abstract artists work from nature and then interpret their subjects in a nonrepresentational manner. In other words, as found on Wikipedia by Answers.com, when abstract art represents the natural world, it â€Å"does so by capturing something of its immutable intrinsic qualities rather than by imitating its external appearance.†(http://www.answers.com/topic /abstract-art)      Historically, abstract art has existed for centuries, as Jewish and Islamic traditional forbids the use of representational art. (http://www.artelino.com/articles/abstract_art.asp) However, the roots of what we generally term â€Å"abstract art†can be traced to the Impressionism movement of the 1880s-1890s. Impressionism disregarded the notion that art was supposed to portray images. Post Impressionism continued this trend and placed more emphasis on the artist’s emotions and expression. Wassily Kandinsky and Kasimir Malevich were the first to really create works that were pure abstraction. Kandinsky was the founder of the Abstraction movement and even published a book detailing his theories on art and spirituality, On the Spiritual in Art. (http://www.artelino.com/articles/abstract_art.asp) Kandinsky created a series of pieces with numbered titles beginning with, â€Å"Improvisation†and â€Å"Composition.†(http://www.ibiblio.org/wm/ paint/auth/kandinsky/) These works were studies in color and line, without an emphasis on representation. While Kandinsky worked in Germany, Malevich spent much of his time in the Russian city of Vitebsk where he taught and founded the UNOVIS, which stood for â€Å"Affirmers of the New Art†and was founded to promote â€Å"collectivity in the creative process†and create a new way of teaching and creating art. (http://www.russianavantgard... ...tational designs and elements, his work can be considered some of the greatest examples of abstract art to date.      Leger, Boccioni and Rothko were all expressing their inner vision. Art is a form of creative expression. Abstract art allowed artists to push the boundaries of creative freedom by favoring design and emotion over representation. But, as the question is posed at paintings.name, â€Å"How free can art be?†(http://paintings.name/) The answer is clear. The only constraint placed by abstract art is that the works are generally nonrepresentational. The artists are free to explore their subjects from various perspectives, geometries and situations. Movement can be show like never before. Merely by adding abstract elements to their works, artists can increase their range. As paintings.name states, â€Å"Contemporary paintings no longer reflect a contraposition between abstract art and figurative art, but these styles either flow together in paintings by contemporary artists, or exist side by side in pure abstract paintings or pure figurative paintings.†(ht tp://paintings.name/) The meaning of abstract art is found in this freedom of choice and expression.

1. 0. INTRODUCTION Meaning of Open Source Software (OSS) Open source software (OSS) is defined as computer software for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that meets the Open Source Definition or that is in the public domain. This permits users to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Meaning of Hardware A computer's hardware consists of the physical components necessary to operate and interact with a computer.Since a computer's primary language is binary, devices are necessary to convert our input into that language. The binary code coming out of the computer must also be translated into something usable for the operator. Meaning of Software Software is often divided into two categories: 1. System software: Includes the operating system and all the utilities that enables the computer to function. `2. Application software: Includes prog rams that do real work for users. For example, word processors, spreadsheets, and database management systems fall under the category of applications software. 4.

The words pervasive and ubiquitous mean â€Å"existing everywhere. † Pervasive computing devices are completely connected and constantly available. Pervasive computing relies on the convergence of  wireless technologies, advanced electronics and the Internet. The goal of researchers working in pervasive computing is to create smart products that communicate unobtrusively. The products are connected to the Internet and the data they generate is easily available. 5. 2 Examples of Pervasive Computing Smart TV [p ic]*Samsung Smart TVSmart TV, which is also sometimes referred to as â€Å"Connected TV†or â€Å"Hybrid TV†, (not to be confused with Internet TV, Web TV, or LG Electronics's upcoming â€Å"SMART TV†branded NetCast Entertainment Access devices), is the phrase used to describe the current trend of integration of the internet and Web 2. 0 features into modern television sets and set-top boxes, as well as the technological convergence between computers and these television sets /set-top boxes. These new devices most often also have a much higher focus on online interactive media, Internet TV, over-the-top content, as well as on-demand streaming media, and less focus on traditional broadcast media like previous generations of television sets and set-top boxes always have had.The technology that enables Smart TVs is not only incorporated into television sets, but also devic es such as set-top boxes, Blu-ray players, game consoles, and other companion devices. These devices allow viewers to search and find videos, movies, photos and other content on the web, on a local cable TV channel, on a satellite TV channel, or stored on a local hard drive. GPS [pic]*Garmin GPS The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. It is maintained by the United States government and is freely accessible by anyone with a GPS receiver.The GPS project was developed in 1973 to overcome the limitations of previous navigation systems, integrating ideas from several predecessors, including a number of classified engineering design studies from the 1960s. GPS was created and realized by the U. S. Department of Defense (USDO D) and was originally run with 24 satellites. It became fully operational in 1994. 6. 0 Conclusion Open Source can be used by anyone and because it has no copyright claims, so users are free to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Pervasive Computing is to make our lives easier because we can interact with computers. Besides that, we can easily give the computer commands and the computer will grant your wish. 2. 0 The Latest Open Source Operating System (OS) 2. 1 Meaning of Open Source OSOpen Source Operating System is the most important program that runs on a computer that is free to use, change, and improve the software, and to redistribute it in modified or unmodified forms. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on t he disk, and controlling peripheral devices such as disk drives and printers. 2. 2 Examples of Open Source OS a) Dream Linux [pic] DreamLinux is a modern and modular Linux system that can be run directly from the CD and optionally be easily installed onto your HD. Dreamlinux comes with a selection of the best applications designed to meet mostly of your daily needs.It is based on Debian and Morphix, which means it takes advantages of their best features and adds its own modern development tools. b) Haiku [pic] Haiku is an open-source operating system currently in development designed from the ground up for desktop computing. Inspired by the BeOS, Haiku aims to provide users of all levels with a personal computing experience that is simple yet powerful, and free of any unnecessary complexities. Haiku is developed mostly by volunteers around the world in their spare time. 3. 0 The Latest Open Source Application Software 3. 1 Meaning of Open Source Application Software Open Sourc e Application Software includes database programs, word processors, and spreadsheets and others.It is free to use, change, and improve the software, and to redistribute it in modified or unmodified forms. 3. 2 Examples of Open Source Application Software Web Browser [pic]*Mozilla Firefox A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resourceis identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content. Hyperlinks present in resources enable users easily to navigate their browsers to related resources. The major web browsers are Internet Explorer, Mozilla Firefox, Google Chrome, Apple Safari, and Opera. Spreadsheet [pic]*Microsoft Office ExcelA spreadsheet is a computer application that simulates a paper, accounting worksheet. It displays multiple cells usually in a two-dimensional matrix or grid consisting of rows and columns. Each cell contains alphanumeric text, numeric values or formulas. A formula defines how the content of that cell is to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated. Spreadsheets are frequently used for financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made. A pseudo third dimension to the matrix is sometimes applied as another layer, or layers/sheets, of two-dimensional data.

Art history formal analysis Renoir luncheon of the boating party Essay
The subject matter of the painting consists of a group of people assembled on an outside deck that has a wooden railing and a red and white striped canopy. The deck is surrounded by marsh grass and some trees with a river visible beyond them. Upon the river a few boats can be seen, one of them a sailboat. In the immediate foreground there’s a square table with a white tablecloth on which rests several empty wine glasses with apparent red wine residue. A few plates are also visible with fluted glasses upon them, discarded morsels of food and silverware can also be seen. A centerpiece dish of fruit composed of Grapes and pears is flanked by several bottles of red wine. A few discarded white cloth napkins have been casually cast among the dishes. Seated to the left of center at the table in the foreground is a young woman wearing straw hat with a red flowered hat band. She wears a fine black dress with white lace edging at the neck and cuffs, a dark red scarf draped over neck and down the front of the dress. She wears a black choker around her neck. She’s holding a small brown furred dog close to her face from under its forelegs the dog sits upright upon the table facing her. Behind her to the left standing and leaning with his backside against the wooden railing of the deck, his right arm gripping the railing stands a large man, his face in profile as he looks to the right and slightly back. He wears a dome shaped straw hat with the brim curved upwards its edge trimmed in blue. He has close cropped reddish brown hair and has a full beard and mustache of the same color. He wears a white tank top shirt and white pants. To his right along the railing several feet behind the foreground table stands a woman bent forward, her left arm and right elbow resting upon the railing as she faces the table. She wears a straw hat with a blue hat band the brim curved down. Her dresses is off white and trimmed in red that the neck and cuffs. Facing her with his back to the table sits a man wearing a brown suit and a brown and bowler hat. Behind the woman at the railing at the far left corner of the deck facing forward stands a man wearing a brown jacket with a light blue shirt wearing a cap. Facing him standing with his back to the viewer facing left is a man wearing a black overcoat and a black top hat with a beard. In the right foreground seated facing the table on a wooden chair that is turned backward is a man who looks left toward the railing of the deck, his face in profile. He faces the woman seated opposite him who holds the dog. He is wearing a straw hat with a flat top and black hatband its brim turned up at the back. He has brown hair and a light brown short mustache. He wears a white tank top shirt and dark colored pants. His arms rest forward on the reversed chair back; in his right hand he holds a cigarette. To his right seated at the table is a woman wearing a white brimless hat with a few blue stripes. Her dress is blue with white ruffles trimmed in red at the neck and white cuffs. Her hair is brown a small round earring can be seen hanging from her right ear as she looks up and to the right. Standing behind her over her left shoulder is a man wearing a cream colored jacket with wispy blue stripes. He wears a white shirt and a black cravat. His hair falls over his forehead and is reddish brown. He has a small mustache and a goatee beard. He is leaning over the woman’s shoulder with his hand resting on the back of her chair, looking down at her. Behind him in the background over his left shoulder is a woman standing facing left, with black gloved hands raised to the sides of her face. She wears an ornate black hat with feathers and a black dress. Standing next to her with his arm around her is a man with a straw hat with a red hat band, wearing a red and white striped shirt. He faces forward looking at her intently. To his right stands another man facing the woman he has his arm around. This man has a full beard and wears a black hat. Behind him seated at the back table is a woman in a flowered straw hat who is drinking from a glass, she looks directly out of the picture plane past the table in the foreground at the viewer. A man seated to her left is barely visible in profile and past the shoulder of the man in the cream colored jacket. The entire scene is brightly lit with ambient light from the open sides of the porch the majority of which were enters from the front left of the picture plane. The white tablecloth on the table in the foreground glows with reflected light and the glasses and bottles on the table twinkle in the light. Part IV – Examination of the Art Objects Medium/Technique/Process Used: The medium used is this painting by Renoir is oil on canvas. The work was painted en plein air (outside) utilizing the alla prima (wet on wet) technique and also the classical layering technique of oil painting employed by the old masters. In these processes the first step would require the preparation of a surface on which to apply the oil paint. A linen canvas would be stretched around a wooden frame and tacked into place. The surface of the canvas would then be protected from the acidic qualities of the oil paint by applying layers of rabbit skin glue and chalk known as a ground. Next a primer of white lead paint or glue mixed with chalk â€Å"gesso†is added to provide a base layer for the painting. A rough outline of the scene would then be sketched onto the canvas as a guide for painting. Next the creation of a palette from which to paint from would require selecting the proper pigments. (Eastlake pg.234) For the portions of this work that were painted en plein air in the alla prima technique in the Impressionist style such as the tableware in the foreground Renoir would have used portable tubes of pigmented paint. Other portions that were executed in his studio employed classical oil painting techniques of layering colors and then glazing which creates a lustrous glow and provides the three dimensional quality of modeling. This technique is evident in the modeling of the forearm and the hand holding the cigarette of the man seated at the table in the right foreground. Colors would then be applied to their proper regions according to the sketch starting with the darkest and ending with the lightest, a mosaic upon which the details and highlights could then be painted. Finally upon completion the painting would be sealed with a varnish to protect its surface. (Sanders pg.11) Part V Examination of the Art Objects Composition (its Form Organization): 1. Identify and describe a specific incidence of composition from the list found below: A. Line: Renoir uses a sharp clean line to define the arm of the man seated at the table in the right foreground. The precise outline of the arm adds to the contrast of color between the arm and the man’s white shirt, the white tablecloth, and chair adding perceived depth to the shape of the arm. In contrast Renoir’s use of line in creating the marsh grasses outside the balcony is loose and diffused, giving the grass a perceived movement and depth. B. Shape: The semi circular shape of the awnings scalloped edge is distorted into curving points giving the illusion that the awning is swaying in the breeze adding a sense of movement to the air that is picked up by the grasses beyond it. C. Space: The open space left of center, framed by the two men in white tank tops allows for an unobstructed view of the landscape beyond providing perspective and contrasts the densely populated right side of the picture adding to the intimacy of the assembled group. This open space also directs the viewer gaze to the centerpiece of the table which is the symbolic heart of this painting. D. Color: Applications red are spread about the painting accenting the amorous qualities of the subjects depicted. Most evident in the women in varying profusion and intensity, the color red highlights the garments at the cuffs and necks, in the flowers they wear on their hats, and on their lips. Although more subtle, accents of red are present on the men as blushes to their face or on their lips. The most overtly amorous male in the right to the back wears a shirt and hat both striped with red. The most overtly sexual female seated, at the table in the left foreground has red tracing her neck and an explosion of red in the flower on her hat. Finally the red striped awning with its tong like flaps covers the entire flirtatious scene. E. Texture: Renoir employs variations in color, shadowing, and white highlights to render the textural appearance of the straw hat worn by the man seated at the table in the right foreground. F. Pattern: The diffused lines of blue/green create a layered pattern in the marsh grasses outside the porch rendering the effect of overlapping leaves with combined density. G. Time and Motion: The motion in this painting is imparted by the marsh grasses and awning gently swaying in the breeze. The aspect of time slowly passing is expressed through the sailboats gliding along the river and in the leisurely poses of the subjects along the railing. 2. At the end of this set of paragraphs identify any art elements you think is not found or used in the art objects composition.

Identifying Emerging Issues in Mobile Learning Essay
The workshop series was funded by the UK’s Joint Information Systems Committee (JISC) as part of the Emerge Community within JISC’s own Users and Innovation research programme. This exploration focused on identifying emerging issues for the sector arising from the increasingly likely large scale use of Smartphones, PDAs and camera phones by learners in HE and FE, both on campus and in the workplace. This was carried out through scenario generation using three different futures prediction tools in three workshops. The following issues were identified as being the most likely to appear in the future of mobile learning five years from now: the increasing use of ‘just in time’ and ‘as and when necessary’ training. the need for always on affordable connectivity and power. increased support for an approach to teaching and learning that is more collaborative than didactic. concerns over scalability; learning communities are divided over whether there is a role for mobile devices in formal teaching, especially in large groups and lectures. oncerns over the merging of personal and vocational information and practice. The strong match between affordances of mobile devices and learning opportunities in work based and experiential learning across the board. increased peer to peer networking and collaboration. the need for design specifications for a secure online all-purpose data repository accessible by different browsers according to device at hand. Other emerging issues for mobile learning in HE and FE include both ethical and practical implications. These include cultural barriers and resistance to change amongst lecturers and associated teaching professionals. Examples are: fears for the erosion of lecturers’ personal time; concerns over security related to the increasing amount of information and number of images to be stored and privacy issues related to the ease with information can be captured in a range of locations. There is also the opportunity to reconsider assessment practices, recording the process of developing an assignment rather than simply marking the product. One last issue, one that is in need of urgent attention, is the need for the development by students and staff of agreed practice, establishing how mobile devices are to be used responsibly in institutions before inconsiderate use or ignorance of their potential to enhance learning results in banning a valuable learning tool.

The workshop series was funded by the UK’s Joint Information Systems Committee (JISC) as part of the Emerge Community within JISC’s own Users and Innovation research programme. This current exploration focuses on identifying emerging issues for the sector arising with the increasingly likely large scale use of Smartphones and mobile phones with the capability to record both video and audio by learners both on campus and in the workplace in HE and FE. These devices have become well established throughout the student community, a survey of 177 students at the University of Southampton found that 94% were regular users and owners of mobile phones (Davidson and Lutman 2007). This dovetails with data from Ofcom (2008) which shows that mobile phone ownership in the 15-24 age group of the UK population is stabilising at around 95% and students to come will be even more experienced in their use. For example, older students in schools that ostensibly ban mobile phones are now regularly being allowed to use the cameras on their ‘phones to record special events or experiments in lessons to help them revise. What is mobile learning? The field of mobile learning has been developing fast as a research topic over the past eight years and accordingly ideas of what exactly mobile learning is have also developed. Winters (2006) noted how various groups researching mobile learning have used definitions that fall into four categories: one – mobile learning as technocentric, where learning is seen as something that makes use of mobile devices, personal digital assistants (PDAs) and mobile phones; two – defined by its relationship to e-learning, where mobile learning is seen as an extension of elearning; three – as augmenting formal education and four – as learner centred, enabling the possibility of lifelong learning. These does not address the unique selling point of mobile learning which is closely linked to the capability of the mobile learner moving between traditionally separate contexts such as the work place and the teaching base supported by handheld technology that they can work with interactively to capture, access and store quantities of information in different multimedia formats. Thus mobile learning can be best described as â€Å"the processes (both personal and public) of coming to know through exploration and conversation across multiple contexts amongst people and interactive technologies†(Sharples, Arnedillo Sanchez, Milrad & Vavoula 2007). Mobile learning in post-compulsory education in the UK A presentation from Traxler & Sugden (2007) places the current state of mobile learning in the UK as consisting of considerable numbers of small scale trials and pilots taking place over fixed periods of time. Confirmation that the practice of using mobile technology to support learning in post-compulsory education is not yet embedded in current practice within institutions was demonstrated during the search for previous research for this paper, where no ongoing large scale uses were found. From currently available sources there is little or no indication as to the extent to which mobile devices are being used in Higher and Further Education. Findings from interviews conducted by Bird and Stubbs (2008) with mobile learning innovators in ten Higher Education Institutions (HEIs) were surprisingly consistent with most respondents reporting that they experienced or expect to experience the same kind of issues. These were mostly in the form of barriers to establishing and sustaining an m-learning innovation in a university 2 environment. Issues which dominated were: skills gaps (in IT support and especially academic staff and somewhat unexpectedly students who despite being heavy users ), lack of technical support (IT services provision), procurement and accounting policies based around PC usage, inclusion issues due to cost of devices and/or data, ethical and legal issues, quality assurance especially with respect to data ownership, sustainability (all projects were based on external funding), device limitations, standards churn, privacy and security, and lack of a ‘killer application’ for the context. Interviews with users trialling PDAs at the Open University (Pettit and Kukulska-Hulme, 2008) indicated that the wireless infrastructure was widely regarded as a critical factor in influencing adoption of the device. Most papers reviewed for the current investigation referred to theoretical speculation about future potential, others discussed projects outside of the UK in Europe or East Asia, however, in the remaining 20%, an impressive range of pilots with different handheld devices was described. These indicate that there is considerable potential for engaging and supporting learners via mobile technologies. These pilots point to greater use of context relevant information especially images and video in learning and to greater collaboration enabled by easily portable, handheld devices connected to the internet via wi-fi or broadband. The following examples indicate the range of activities tested and are included by sector. Higher education Lecturers have evaluated a range of devices from multi-function PDAs and Smartphones to simple texti messaging (SMS). In one of the first examples of the use of PDA’s in an undergraduate setting Ramsden (2005) successfully tested giving undergraduate Economics students at the University of Bristol access to VLE’s and course materials via internet-enabled PDAs. As well as enabling access to course resources any time, anywhere, having the PDA allowed the students to hold question and answer sessions via the online discussion board during lectures which they found this particularly helpful. The University of Birmingham has evaluated the use of PocketPC handheld computers to offer multiple mobile applications to university students in the form of a ‘mobile learning organiser’. The main uses were for issues of time and course management and access to course materials. Other functions included the ability to communicate via email and instant messaging and to organise notes. The participating students made good use of the calendar and timetable facilities as well as communication tools and were keen for more content to be delivered in this manner. (Corlett et al, 2005) At London Metropolitan University the Reusable Learning Objects (RLO) Centre for Excellence in Teaching and Learning (CETL) works on the design, development and use of learning objects many of which run on mobile phones. Smith et al (2007) discuss the motivation they have seen in students (sports science in this case) to learn via subject specific learning objects (programs) such as Flash animations of muscle groupings and movements that run on their own or loaned mobile phones. Other animated tutorials, language learning for example, include multiple choice quizzes (Tschirhart et al, 2008). In another study Cook, Pachler and Bradley (2008) found that loaning postgraduate students Nokia N91 phones to make notes and take images for upload to web based media board such as Lifeblog and tribal’s Mediaboard led to blurring the boundaries between study, work, and personal time and between formal and informal practice. In the Spatial Literacy in Teaching (SPLINT) CETL at the Universities of Nottingham and Leicester applications aimed at Geography students are being developed for PDAs and tablet PCs where the PDA screen is held up towards the real scene to offer additional information about that scene, ‘augmenting’ reality for the user (Priestnall and Polmear, 2007). For example, trials of a PDA application designed to teach the geomorphology of the Lake District, NW England showed that students the students learned to appreciate the power of geocontextualised visualisation to support their understanding of landscape processes (Jarvis et al, 2008). The University of Nottingham has used mobile phones and similar software to enable group blogging as a tool to support Chinese students in the process of enculturation as they get used to a new society and to enter the local community. The â€Å"learners showed a obvious interest in flexibility of time and space that potentially extends ‘antennas’ of the group blog to deeper insight of local culture. †(Shao, Crook & Koleva, 2007). Other examples used simpler devices and text messaging. The Mobiles Enhancing Learning and Support (MELaS) project saw the University of Wolverhampton test using text messaging with first year undergraduates in five departments aiming to enhance the student learning experience. In all 27 staff successfully interacted with 938 different students through at least one of: one way (staff to learner) communication, formative assessment with feedback, and a collaborative learning discursive tool (Brett, 2008). In another study sports education students at the University of Bath reported that SMS messages to their mobile phones from faculty were found welcome in assisting them to learn time management skills and as an extension of the tutor’s voice beyond the traditional lecture environment. This helped to reduce the perceived psychological distance between students, their peers and tutors (Jones, Edwards & Reid, 2008). SMS messaging has been trialled in lecture theatres too. Elliman (2006) reports successfully using a system that allowed students to provide feedback by SMS on their level of comprehension during a lecture. The system displays a histogram showing understanding level which is continually updated during the lecture together with comments and question in a scrolling area of the screen. At Brunel University, first year undergraduate Information and Communications Technology (ICT) students found that revision podcasts, downloaded to their personal digital media players were popular and perceived as more effective than revising from traditional textbooks (Evans 2008). In a review of podcasting to support distance learning in the Open University, UK Minocha and Booth (2008) conclude that audio technologies such as podcasts can not only support mobile learning but also entice, motivate, inform and reinforce. Further Education Mobile technology has been used in a number of colleges as a means to bring new learning opportunities to students who might otherwise not have access to college education. Many of these projects have been funded by the Learning and Skills Council under the MoleNET initiative or by the JISC e-Learning Programme. At Pembrokeshire College, an mlearning trial project was carried out from 2005-7 to support NEET students (NEET – not in education, employment or training) with reentry to education, training or work. Giving students access to PDA’s helped to engage them and improve communication with a difficult to reach group. The use of SMS messaging enabled the teachers to keep in touch with this very transient group of learners and helped identify opportunities for learning as when they occurred. (Pembrokeshire College 2007). Similar projects working with NEET learners have also been carried out at Accrington and Rossendale College, Tower Hamlets College and Weston College (MoLeNET 2008). 4 Having the capability to learn anywhere by means of handheld PDAs allowed Dewsbury College and Bishop Burton College, West Yorkshire to provide learners in outreach centres and workplace learning environments with similar access to learning resources as their peers on the main college campus (JISC 2005a). Mobile phones have also been found useful to help in location based learning. The City of Southampton College has been assisting ESOL (English for speakers of other languages) students to improve their opportunities for meaningful language interactions. Visiting locations within the city to help get to know their locality, students were asked location specific questions answered through SMS messaging and posting images to an interactive website. The project found that such techniques enhanced the students’ literacy and numeracy skills and helped to engage hard to reach learners such as those from the multiethnic Southampton community where many students have English as a second language (JISC 2005b). As in Higher Education bulk text messaging services to support managing learning have proved popular with most students. There are those for whom this sort of service is particularly useful. Derwen College (JISC, 2008a) found that their students who have varying degrees of physical disabilities and learning difficulties responded well to reminders to students for things like surgery and other appointments, dinner times and class notifications. Simple text based interaction was also used at Lakes College West Cumbria (JISC, 2008b) who piloted the use of iPod nanos to provide multiple choice revision quizzes for Construction students, many of whom have learning difficulties and struggle with paper-based revision processes. The iPod quizzes proved popular with every student in the cohort making use of the iPods during the revision period. The use of handheld devices to record or view multimedia to support learning is also proving popular. At Southwark College students are using low-priced, pocket-sized camcorders to overcome some of the technical and organisational barriers to using video in the classroom and for recording evidence of learning (JISC, 2008c). Examples included recording students’ oral presentations in English which were then used by the students for practice and reviewing with each other and Level 2 students in Art and Design recording technique demos and talking about their work to inform Level 1 students hoping to progress. Other projects, such as My Podcast at New College, Swindon (Warren, 2008), involve podcasting with lecturers creating both audio and video podcasts that students can download and play on handheld PDA’s or MP3 players for revision or extra support with a topic wherever they happen to be, in the workplace, at home or in college or moving between the two. Work Based Learning Both HE and FE institutions place students training for professions, whether medicine, building, teaching or hairdressing etc. in the workplace for a significant proportion of their course. Students, often at considerable distance from their teaching bases, need online access to course materials and other context specific information, to communicate with their tutors and to produce records of their progress and assignments for assessment. Mentors in the workplace need to authenticate and support this student learning. A number of pilots have been set up to test how mobile technologies can successfully be used to support students on work placements. For instance, mobile devices have been used to give instant hands on access to information that would be difficult to carry around on the job. At the James Cook University Hospital in 5 Middlesborough, 5th year medical students tested the use of PDA’s providing access to formulae, clinical guidelines, electronic portfolios and other web-based materials. They found portable access to these facilities useful, as was the ability for supervisors to ‘sign-off’ log books using their normal signatures on the PDA. (Cotterill et al, 2008). Reynolds et al (2007) found that a PDA proved to be a convenient and versatile mode of access to online education for dentistry students at King’s College, London. The 12 students were most positive about being able to make notes for individual study, to keep a diary of their commitments to teaching sessions and to having on the spot access to online support materials, particularly videos. Teaching is another profession where students need access to a wealth of information. Wishart et al (2007) found that when student teachers trialled the use of PDA’s in school they deemed the calendar or diary to be articularly supportive. Email was also used, primarily to maintain contact with other students and the university tutor, and the web browser was used to access information both in class and for personal reasons. Some students used spreadsheets to record pupils’ attendance and grades and most, in this pilot involving 14 trainees, used the word processor to make notes from meetings and on lesson observations for essays. However, the prevailing sociocultural climate where mobile phones are often banned and PDA’s a rarity meant that trainees often felt uncomfortable using their device on school premises. In FE mobile technology has been used in the work place for just in time problem solving, such as through the Hairdressing Training programme developed by the University of Manchester’s data centre, Mimas, and now used by 500 students at Stockport College, which offers step-by step guides to hairdressing techniques for styling, colouring and cutting (Smith, 2008) Also PDA’s have been found to be useful in connecting work based learners in FE who may otherwise be isolated from learning opportunities. Such devices have been used to assist apprentices in remote rural locations in Lincolnshire to give flexible learning options and to build achievement and self-esteem (Lambourne, 2008) and to provide learning and social networking opportunities to care workers in schools and nursing establishments in the Bourneville area of Birmingham (Brown, 2008). Finally, one of the largest trials of mobile technology in the workplace, currently ongoing with around a 1000 students in five universities in Yorkshire, is that being run by the Assessment of Learning in Practice Settings (ALPS) CETL1, a Centre for Excellence in Teaching and Learning that focuses on assessment and learning in practice settings and involving nursing and allied health care practitioner trainees. Initial indications (Dearnley et al, 2008) showed that both students and lecturers were positive about a range of benefits having a PDA enables however, introducing mobile technology into the clinical setting will require a significant shift in culture and a significant level of training and support. 1 http://www. alps-cetl. ac. uk/ 6 Summary While the above mentioned projects demonstrate the range of learning activities that have been trialled in UK institutions, recent advances in the abilities of the mobile devices themselves offer the chance to deliver new services to learners that have not yet been tested. The 2009 Horizon Report notes how the adoption of novel interfaces (like the iPhone), the new ability of mobile devices to download applications and to be location aware through GPS signals, all offer new opportunities for learning. With the addition of broadband-like data connections, the boundary between what is a mobile phone and a portable computer are being ever more blurred (New Media Consortium 2009). It is in this technology context that the workshop participants came together to imagine future scenarios for the use of mobile technology in learning, drawing on their wide experiences of previous research projects and contemplating how developing mobile technologies could open up new opportunities for connecting learners and teachers. 7 Methods: Developing Future Scenarios In this project three different tools were used to support future predictions. The first used for the workshop focusing on the practice of users in Higher Education (HE) in the future five years from today was the Cognitive Foresight toolkit available from the UK Government Department for Innovation, Universities and Skills (Office of Science and Technology, 2005). It was developed for strategic futures planning and provides guidance on different techniques that can be used in the different stages of developing future scenarios and the ways they can be combined. This first workshop employed driver analysis to build internally consistent future scenarios from an assessment of the way current trends and drivers are influencing the present use of mobile technologies in HE. First the workshop participants ‘brainstorm’ a range of drivers for the currently observable trends. Next scenarios are produced by taking the drivers identified as having the highest importance and highest impact as orthogonal pairs of axes and visualising up to four scenarios that match the chosen combinations. This method is illustrated in the example below. More of †¦ Scenario Decrease in †¦ Increase in †¦ Less of †¦ The second used the Futures Technology Workshop method (Vavoula and Sharples, 2007) to look at future scenarios in work based learning. This is a structured method whereby people, in this case with experience in the specific area of the use of mobile technologies in education, envision and design the interactions between current and future technologies and an activity. Through a series of structured workshop sessions they collaborate to envisage future activities related to technology design, build models of the contexts of use for future technologies, act out scenarios of use for their models, re-conceive their scenarios in relation to present-day technologies, list problems with implementing the scenarios exploring the gap between current and future technology and activity. The workshop method was edited slightly within the time constraints of the day so that the structured sessions comprised: i. i. Imagineering: brainstorm on desired future learning activities. Modelling: in groups, producing models that demonstrate the envisioned activities, complete with related props. 8 iii. iv. Retrofit: developing a role play for another group’s scenario using only current technologies. Futurefit Requirements: listing requirements for the future technologies that have to be in place for the scenario to be realised. The third workshop on future scenarios in Further Education (FE) followed a method devised by FutureLab, an educational thinktank aimed at transforming the way people learn that focuses on the potential offered by digital and other technologies. This method for developing scenarios uses non-specific images of people of different ages in different locations printed on cards as a stimulus to thinking. The workshop used cards such as these shown below from the Building Visions for Learning Spaces sequence of cards. The workshop participants are then asked to envision first a range of learning activities that could be happening within the image and the people involved in them, then the anticipated outcomes and the technological resources that will be needed. One of these activities is then chosen by each of the groups for fuller development into a future scenario. In each of the above three cases the workshop was set up to start with two initial keynote presentations designed to stimulate thought and discussion from recognised experts. These keynotes (found under workshops 8-10) are available from the Adding a Mobile Dimension to Teaching and Learning web site2. These were followed by a series of discussion activities informed by the futures prediction method being used and facilitated by the research team. A discussion workshop is a recognised method of collaborative knowledge construction through discussion and debate amongst peers or experts. The workshops were run as focus groups with the facilitator encouraging discussion and debate and following a qualitative, phenomenological research approach.
