Why be Moral in a Virtual World

This article considers two related and fundamental issues about morality in a virtual world. The first is whether the anonymity that is a feature of virtual worlds can shed light upon whether people are moral when they can act with impunity. The second issue is whether there are any moral obligations in a virtual world and if so what they might be. Our reasons for being good are fundamental to understanding what it is that makes us moral or indeed whether any of us truly are moral. Plato grapples with this problem in book two of The Republic where Socrates is challenged by his brothers Adeimantus and Glaucon. They argue that people are moral only because of the costs to them of being immoral; the external constraints of morality. Glaucon asks us to imagine a magical ring that enables its wearers to become invisible and capable of acting anonymously. The ring is in some respects analogous to the possibilities created by online virtual worlds such as Second Life, so the dialogue is our entry point into considering morality within these worlds. These worlds are three dimensional user created environments where people control avatars and live virtual lives. As well as being an important social phenomenon, virtual worlds and what people chose to do in them can shed light on what people will do when they can act without fear of normal sanction. This paper begins by explaining the traditional challenge to morality posed by Plato, relating this to conduct in virtual worlds. Then the paper will consider the following skeptical objection. A precondition of all moral requirements is the ability to act. There are no moral requirements in virtual worlds because they are virtual and it is impossible to act in a virtual world. Because avatars do not have real bodies and the persons controlling avatars are not truly embodied, it is impossible for people to truly act in a virtual world. We will show that it is possible to perform some actions and suggest a number of moral requirements that might plausibly be thought to result. Because avatars cannot feel physical pain or pleasure these moral requirements are interestingly different from those of real life. Hume’s arguments for why we should be moral apply to virtual worlds and we conclude by considering how this explains why morality exists in these environments

Book review: why America needs a left: a historical argument

The United States today cries out for a robust, self–respecting, intellectually sophisticated left, yet the very idea of a left appears to have been discredited. In this recent book, Eli Zaretsky rethinks the idea by examining three key moments in American history: the Civil War, the New Deal and the range of New Left movements in the 1960s and after including the civil rights movement, the women′s movement and gay liberation. Emily Coolidge Toker recommends the book to anyone looking for a quick and convincing call to action

Why Didn’t Subprime Investors Demand a (Much Larger) Lemons Premium?

The subprime crisis would never have occurred had investors not been such enthusiastic consumers of subprime securities. The investors now say, somewhat self-servingly (but probably correctly), that they did not understand the securities -- securities for which they were willing to pay very high prices. Investors\u27 willingness to purchase these securities on terms that were favorable to the sellers, and unfavorable to them, presents a considerable puzzle. Investors do not want to miss out on the next big thing

Why the Tsirelson Bound? Bub's Question and Fuchs' Desideratum

To answer Wheeler's question "Why the quantum?" via quantum information theory according to Bub, one must explain both why the world is quantum rather than classical and why the world is quantum rather than superquantum, i.e., "Why the Tsirelson bound?" We show that the quantum correlations and quantum states corresponding to the Bell basis states, which uniquely produce the Tsirelson bound for the Clauser-Horne-Shimony-Holt quantity, can be derived from conservation per no preferred reference frame (NPRF). A reference frame in this context is defined by a measurement configuration, just as with the light postulate of special relativity. We therefore argue that the Tsirelson bound is ultimately based on NPRF just as the postulates of special relativity. This constraint-based/principle answer to Bub's question addresses Fuchs' desideratum that we "take the structure of quantum theory and change it from this very overt mathematical speak ... into something like [special relativity]." Thus, the answer to Bub's question per Fuchs' desideratum is, "the Tsirelson bound obtains due to conservation per NPRF."Comment: Contains corrections to the published versio

Why is it difficult to implement e-health initiatives? A qualitative study

<b>Background</b> The use of information and communication technologies in healthcare is seen as essential for high quality and cost-effective healthcare. However, implementation of e-health initiatives has often been problematic, with many failing to demonstrate predicted benefits. This study aimed to explore and understand the experiences of implementers - the senior managers and other staff charged with implementing e-health initiatives and their assessment of factors which promote or inhibit the successful implementation, embedding, and integration of e-health initiatives.<p></p> <b>Methods</b> We used a case study methodology, using semi-structured interviews with implementers for data collection. Case studies were selected to provide a range of healthcare contexts (primary, secondary, community care), e-health initiatives, and degrees of normalization. The initiatives studied were Picture Archiving and Communication System (PACS) in secondary care, a Community Nurse Information System (CNIS) in community care, and Choose and Book (C&B) across the primary-secondary care interface. Implementers were selected to provide a range of seniority, including chief executive officers, middle managers, and staff with 'on the ground' experience. Interview data were analyzed using a framework derived from Normalization Process Theory (NPT).<p></p> <b>Results</b> Twenty-three interviews were completed across the three case studies. There were wide differences in experiences of implementation and embedding across these case studies; these differences were well explained by collective action components of NPT. New technology was most likely to 'normalize' where implementers perceived that it had a positive impact on interactions between professionals and patients and between different professional groups, and fit well with the organisational goals and skill sets of existing staff. However, where implementers perceived problems in one or more of these areas, they also perceived a lower level of normalization.<p></p> <b>Conclusions</b> Implementers had rich understandings of barriers and facilitators to successful implementation of e-health initiatives, and their views should continue to be sought in future research. NPT can be used to explain observed variations in implementation processes, and may be useful in drawing planners' attention to potential problems with a view to addressing them during implementation planning

Why do gallium clusters have a higher melting point than the bulk?

Density functional molecular dynamical simulations have been performed on Ga$_{17}$ and Ga$_{13}$ clusters to understand the recently observed higher-than-bulk melting temperatures in small gallium clusters [Breaux {\em et al.}, Phys. Rev. Lett. {\bf 91}, 215508 (2003)]. The specific-heat curve, calculated with the multiple-histogram technique, shows the melting temperature to be well above the bulk melting point of 303 K, viz. around 650 K and 1400 K for Ga$_{17}$ and Ga$_{13}$, respectively. The higher-than-bulk melting temperatures are attributed mainly to the covalent bonding in these clusters, in contrast with the covalent-metallic bonding in the bulk.Comment: 4 pages, including 6 figures. accepted for publication in Phys.

Why Are Wage Profiles so Flat During the First Year on a Job?

This paper presents evidence that productivity net of general training costs rise 4 or 5 times more rapidly than wage rates during the first 2 years on a job. This occurs for three reasons. First, sorting, high job search costs and the reputational damages that result from premature separations cause workers to prefer front loaded compensation packages which reduce the likelihood of involuntary terminations. Second, due to progressive income taxation and poor access to credit, workers discount the future more heavily than employers. Front-loading compensation is, therefore, a relatively cheap way for employers to attract top quality new hires. Finally, the minimum wage and union contracts also tend to force flat wage profiles

Why Your Academic Library Needs a Popular Reading Collection Now More Than Ever

Do popular reading materials belong in college and university libraries? Although some librarians think not, others believe there are compelling reasons for including them. The trend towards user-focused libraries, the importance of attracting patrons to libraries in the age of the Internet, and, most importantly, the need to promote literacy at a time when it has reached its lowest levels are all reasons why academic librarians are reconsidering their ideas about popular reading materials. Librarians who decide to implement a leisure reading collection should consider a number of key issues
