This book offers new ways of thinking about and assessing the impact of virtual reality on its users. It argues that we must go beyond traditional psychological concepts of VR "presence" to better understand the many varieties of virtual experiences. The author provides compelling evidence that VR simulations are capable of producing "virtually real" experiences in people. He also provides a framework for understanding when and how simulations induce virtually real experiences. From these insights, the book shows that virtually real experiences are responsible for several unaddressed ethical issues in VR research and design. Experimental philosophers, moral psychologists, and institutional review boards must become sensitive to the ethical issues involved between designing "realistic" virtual dilemmas, for good data collection, and avoiding virtually real trauma. Ethicists and game designers must do more to ensure that their simulations don’t inculcate harmful character traits. Virtually real experiences, the author claims, can make virtual relationships meaningful, productive, and conducive to welfare but they can also be used to systematically mislead and manipulate users about the nature of their experiences. The Ethics of Virtual and Augmented Reality will appeal to philosophers working in applied ethics, philosophy of technology, and aesthetics, as well as researchers and students interested in game studies and game design.
In the late nineteenth century, the disintegration of the silver-mining economy that had survived since the colonial period effected fundamental economic and social changes in southern Bolivia. The changes took three forms: increased conflict between peasants and elites, expanded concentration of land into large estates, and worsened labor conditions among the peasants. This study concentrates on the four provinces in the department of Chuquisaca, using them as case studies of how and why rural peoples adapted to and resisted the changes in their lives. Resistance took many forms: strikes, rebellions, insurrections, court challenges, banditry, and flight. In the reactions to change in these provinces, the author sees certain common characteristics that transcend the region and can be discerned in other parts of Latin America. On the basis of the Chuquisaca experience, he also questions the validity of current theories of peasant resistance and rebellion. The author describes the reactions of the oligarchy based in Sucre, the capital, to the decline of silver as Bolivia's major export, showing how they attempted to regain their preeminent financial and political position by a number of strategies, notably the expansion of the hacienda system. This expansion gave rise to different problems in each of the four provinces: in Yamparaez, fierce resistance by the Indian communities to any changes; in Cinti, violent labor disputes brought on by the creation of enormous agro-industrial estates; in Azero, Indian attempts to escape debt peonage by migrating or by joining Franciscan missions; and in Tomina, widespread banditry. The final chapter compares and contrasts the various forms of rural resistance in the context of their social, economic, and cultural foundations.
Vitamins are a group of physiologically very important, chemically quite complex organic compounds, that are essential for humans and animals. Some vitamins and other growth factors behave as antioxidants, while some can be considered as biopigments. As their chemical synthesis is laborious, their biotechnology-based synthesis and production via microbial fermentation has gained substantial interest within the last decades. Recent progress in microbial genetics and in metabolic engineering and implementation of innovative bioprocess technology has led to a biotechnology-based industrial production of many vitamins and related compounds. Divided into three sections, this volume covers: 1. water-soluble vitamins 2. fat-soluble vitamin compounds and 3. other growth factors, biopigments, and antioxidants. They are all reviewed systematically: from natural occurrence and assays, via biosynthesis, strain development, to industrially-employed biotechnological syntheses and applications.
Beyond Mobility" also seeks to rethink how projects are planned and designed in cities and suburbs at multiple geographic scales, from micro-designs such as parklets to corridors and city-regions. The book closes with a reflection on the opportunities and challenges in moving beyond mobility, with attention to emerging technologies such as self-driving cars and ride-hailing services and social equity topics such as accessibility, livability, and affordability.
