Invisible Users by Jenna Burrell Pdf

An account of how young people in Ghana's capital city adopt and adapt digital technology in the margins of the global economy. The urban youth frequenting the Internet cafés of Accra, Ghana, who are decidedly not members of their country's elite, use the Internet largely as a way to orchestrate encounters across distance and amass foreign ties—activities once limited to the wealthy, university-educated classes. The Internet, accessed on second-hand computers (castoffs from the United States and Europe), has become for these youths a means of enacting a more cosmopolitan self. In Invisible Users, Jenna Burrell offers a richly observed account of how these Internet enthusiasts have adopted, and adapted to their own priorities, a technological system that was not designed with them in mind. Burrell describes the material space of the urban Internet café and the virtual space of push and pull between young Ghanaians and the foreigners they encounter online; the region's famous 419 scam strategies and the rumors of “big gains” that fuel them; the influential role of churches and theories about how the supernatural operates through the network; and development rhetoric about digital technologies and the future viability of African Internet cafés in the region. Burrell, integrating concepts from science and technology studies and African studies with empirical findings from her own field work in Ghana, captures the interpretive flexibility of technology by users in the margins but also highlights how their invisibility puts limits on their full inclusion into a global network society.

People and Computers XVI - Memorable Yet Invisible by Xristine Faulkner,Janet Finlay,Francoise Detienne Pdf

For the last 20 years the dominant form of user interface has been the Graphical User Interface (GUl) with direct manipulation. As software gets more complicated and more and more inexperienced users come into contact with computers, enticed by the World Wide Web and smaller mobile devices, new interface metaphors are required. The increasing complexity of software has introduced more options to the user. This seemingly increased control actually decreases control as the number of options and features available to them overwhelms the users and 'information overload' can occur (Lachman, 1997). Conversational anthropomorphic interfaces provide a possible alternative to the direct manipulation metaphor. The aim of this paper is to investigate users reactions and assumptions when interacting with anthropomorphic agents. Here we consider how the level of anthropomorphism exhibited by the character and the level of interaction affects these assumptions. We compared characters of different levels of anthropomorphic abstraction, from a very abstract character to a realistic yet not human character. As more software is released for general use with anthropomorphic interfaces there seems to be no consensus of what the characters should look like and what look is more suited for different applications. Some software and research opts for realistic looking characters (for example, Haptek Inc., see http://www.haptek.com). others opt for cartoon characters (Microsoft, 1999) others opt for floating heads (Dohi & Ishizuka, 1997; Takama & Ishizuka, 1998; Koda, 1996; Koda & Maes, 1996a; Koda & Maes, 1996b).

Invisible Friends by Victor E. Furness and Barbara M. Horne Pdf

Every child has a fear or a special need. The Invisible Friends series was written with the sole purpose of reaching just one child that feels he or she is all alone or that nobody understands. The Logan's Poems section was written for Barbara's youngest grandson, who has special medical needs. This poetry section is meant to make children think, laugh, and remember. This book is also written to help both children and parents laugh, and it may possibly make them think and shake their heads. Invisible Friends is dedicated to Victor's mother and Barbara's friend, Hazel Furness. Logan, Barbara's youngest grandson, suffers from a mixture of ADHD, Asperger Syndrome, and light autism. The poems were written to help Logan learn to laugh and be proud of himself. This, in turn, makes life easier on his brothers and sisters. Barbara Horne was blessed with two daughters, Tammy and Connie, twin sons, James and John, and seven grandchildren. Writing poetry is her deep passion. As a cancer survivor, she knows the power of children's laughter. Victor Furness has a son, Robert, who has Aspergers syndrome. Being mentally challenged, Robert was bullied in school. This inspired Victor to write children's stories full of hope and understanding.

Invisible Friends by Doug Simpson Pdf

Listening to the chatter of her six-year-old daughter, Cammi, Connie Cantland begins to wonder if Cammi's imaginary friend could be more than just imaginary. Connie knows her friend and coworker, Dani, believes in the survival of souls after the death of bodies, and the reincarnation of souls, so she shares her concerns with Dani about Cammi's supposed friend. Dani introduces Connie to Dacque LaRose: a friend and mentor on souls and reincarnation. Connie and Dacque's conversations propel Connie and her husband Carson into an educational journey into reincarnation of souls, soul groups, past life regression sessions, spirit guides, and conversations with souls, of which Connie and Carson previously had absolutely no knowledge of.

Invisible Labor by Marion Crain,Winifred Poster,Miriam Cherry Pdf

"Demographic and technological trends have yielded new forms of work that are increasingly more precarious, globalized, and brand centered. Some of these shifts have led to a marked decrease in the visibility of work or workers. This edited collection examines situations in which technology and employment practices hide labor within the formal paid labor market, with implications for workplace activism, social policy, and law. In some cases, technological platforms, space, and temporality hide workers and sometimes obscure their tasks as well. In other situations, workers may be highly visible--indeed, the employer may rely upon the workers' aesthetics to market the branded product--but their aesthetic labor is not seen as work. In still other cases, the work occurs within a social interaction and appears as leisure--a voluntary or chosen activity--rather than as work. Alternatively, the workers themselves may be conceptualized as consumers rather than as workers. Crossing the occupational hierarchy and spectrum from high- to low-waged work, from professional to manual labor, and from production to service labor, the authors argue for a broader understanding of labor in the contemporary era. This book adopts an interdisciplinary approach that integrates perspectives from law, sociology, and industrial/labor relations"--Provided by publisher.

All My Friends Are Invisible by Jonathan Joly Pdf

*A mesmeric, harrowing and ultimately uplifting childhood memoir about identity, family and mental health that has touched so many readers around the world* 'So raw and full of so many emotions. I didn't want the book to end' @ftsworld 'It's hard to put into words how sacred this book is' @lisainthecity27 'I've literally read it in one sitting. Glued to every single word' @lorencoles 'Thank you for shining a light on 'different' children. Thank you for showing that there is no normal. But most of all thank you for proving that even when it's hard to make friends...there is always someone looking out for you' @gabrielle.rea It was an ordinary day in 2016. In Gatwick Airport, Jonathan and his wife Anna were having breakfast with their two little children while waiting for their flight to be called. And then it happened, a familiar sensation that Jonathan hadn't had for decades: an out-of-body experience that transported him to another place, the safe place he used to escape to in his mind when he was a boy. Because growing up in conservative 1980s Dublin, where there was little tolerance for children who were 'different', Jonathan Joly was, indeed, a different sort of child: creative, expressive, and - on the inside - a girl. The limitations of the people around him to understand his differences led to years of tyrannical bullying and abuse, forcing him to withdraw within himself to the point of clinical absence. His only chance for survival was the inner world he created for himself, rich with loving and supportive friends and playmates, that only he could see. Jonathan's invisible friends were his lifeline, and on that day at the airport, they came flooding back, and have remained with him to this day. This extraordinary childhood memoir is not only an important, thought-provoking and exhilarating read, it gives hope and community for all those who have ever felt 'other', and proves how vital it is to provide children with the safe space to be themselves. In All My Friends are Invisible, Jonathan Joly, known widely as one of social media's most successful content creators, shares the secret he's kept hidden these many years. He shows the beautiful world he retreated to time and time again when life was unbearable for his 'skin machine'. Most importantly, he introduces us to his invisible friends, and in so doing you may be transported back to the friends you had as a child that no one else could see, and who may have saved you, too. 'This will blow you away'- Stylist 'Joly's prose is sensitive and heartbreaking...darkly compelling' - Business Post 'An extraordinary and thought-provoking memoir' - Belfast Telegraph

MIMO Wireless Networks by Bruno Clerckx,Claude Oestges Pdf

This book is unique in presenting channels, techniques and standards for the next generation of MIMO wireless networks. Through a unified framework, it emphasizes how propagation mechanisms impact the system performance under realistic power constraints. Combining a solid mathematical analysis with a physical and intuitive approach to space-time signal processing, the book progressively derives innovative designs for space-time coding and precoding as well as multi-user and multi-cell techniques, taking into consideration that MIMO channels are often far from ideal.Reflecting developments since the first edition was published, this book has been thoroughly revised, and now includes new sections and five new chapters, respectively dealing with receiver design, multi-user MIMO, multi-cell MIMO, MIMO implementation in standards, and MIMO system-level evaluation. Extended introduction to multi-dimensional propagation, including polarization aspects Detailed and comparative description of physical models and analytical representations of single- and multi-link MIMO channels, covering the latest standardized models Thorough overview of space-time coding techniques, covering both classical and more recent schemes under information theory and error probability perspectives Intuitive illustration of how real-world propagation affects the capacity and the error performance of MIMO transmission schemes Detailed information theoretic analysis of multiple access, broadcast and interference channels In-depth presentation of multi-user diversity, resource allocation and (non-)linear MU-MIMO precoding techniques with perfect and imperfect channel knowledge Extensive coverage of cooperative multi-cell MIMO-OFDMA networks, including network resource allocation optimization, coordinated scheduling, beamforming and power control, interference alignment, joint processing, massive and network MIMO Applications of MIMO and Coordinated Multi-Point (CoMP) in LTE, LTE-A and WiMAX Theoretical derivations and results contrasted with practical system level evaluations highlighting the performance of single- and multi-cell MIMO techniques in realistic deployments

Erasing the Invisible Hand by Warren J. Samuels Pdf

This book examines the use, principally in economics, of the concept of the invisible hand, centering on Adam Smith. It interprets the concept as ideology, knowledge, and a linguistic phenomenon. It shows how the principal Chicago School interpretation misperceives and distorts what Smith believed on the economic role of government. The essays further show how Smith was silent as to his intended meaning, using the term to set minds at rest; how the claim that the invisible hand is the foundational concept of economics is repudiated by numerous leading economic theorists; that several dozen identities given the invisible hand renders the term ambiguous and inconclusive; that no such thing as an invisible hand exists; and that calling something an invisible hand adds nothing to knowledge. Finally, the essays show that the leading doctrines purporting to claim an invisible hand for the case for capitalism cannot invoke the term but that other nonnormative invisible hand processes are still useful tools.

User Interfaces for All by Constantine Stephanidis Pdf

User Interfaces for All is the first book dedicated to the issues of Universal Design and Universal Access in the field of Human-Computer Interaction (HCI). Universal Design (or Design for All) is an inclusive and proactive approach seeking to accommodate diversity in the users and usage contexts of interactive products, applications, and services, starting from the design phase of the development life cycle. The ongoing paradigm shift toward a knowledge-intensive information society is already bringing about radical changes in the way people work and interact with each other and with information. The requirement for Universal Design stems from the growing impact of the fusion of the emerging technologies, and from the different dimensions of diversity, which are intrinsic to the information society. This book unfolds the various aspects of this ongoing evolution from a variety of viewpoints. It's a collection of 30 chapters written by leading international authorities, affiliated with academic, research, and industrial organizations, and non-market institutions. The book provides a comprehensive overview of the state of the art in the field, and includes contributions from a variety of theoretical and applied disciplines and research themes. This book can also be used for teaching purposes in HCI courses at the undergraduate as well as graduate level. Students will be introduced to the human-, organizational-, and technology-oriented dimensions that call for a departure from traditional approaches to user interface development. Students will also get an overview of novel methods, techniques, tools, and frameworks for the design, implementation, and evaluation of user interfaces that are universally accessible and usable by the broadest possible end-user population. This comprehensive book is targeted to a broad readership, including HCI researchers, user interface designers, computer scientists, software engineers, ergonomists and usability engineers, Human Factors researchers and practitioners, organizational psychologists, system/product designers, sociologists, policy- and decision makers, scientists in government, industry and education, as well as assistive technology and rehabilitation experts.

Invisible Friends by Alan Ayckbourn Pdf

Alan Ayckbourn's play is about a very ordinary teenager called Lucy. With her father glued to the cowboys on the telly, her mother preoccupied with neighbourly gossip and her brother enclosed in his ear-phones, no one wants to know about her place in the school swimming team. So Lucy revives her childhood fantasy friend, Zara, setting a place for her at the very ordinary tea table. This time Zara materializes, bringing with her an idealized father and brother, and showing Lucy how to make her real family vanish. The moral of this cautionary tale is carefully spelt out - that when you get what you want it's not what you wanted - as Lucy's dream family turns out to be a nightmare. The play is supposedly for children of seven upwards, but there's a message here for parents, too, about listening to kids.
