Downloading culture: community building in a decentralized file-sharing collective

File-sharing collectives have significantly disrupted models of digital media distribution since their emergence and widespread popularization in the late 1990s. This study investigates how semi-anonymous and decentralized collectives construct their communities of practice. Conducting a case study of a private torrenting community, data were gathered via participant observation, interviews, and online postings (i.e., blogs and forums). Findings challenged dominant notions of opportunism, selfishness and task-oriented individualism advanced by Human–Computer Interaction scholars. Three key constructs were identified in private torrent community building: boundary construction, membership maintenance, and a sense of belonging and solidarity. Findings illustrate how a file-sharing community cultivates the formation of prosocial digital peers, fosters an affective approach to peer-to-peer collectives, and ultimately forges a downloading virtuoso community. This sisyphean, goal-oriented community seeks to create a comprehensive archive of media artifacts independent of and in opposition to dominant corporate platforms. The community demonstrates a downloading culture inspired by technological design, yet driven by trust and solidarity.     

Computer experiments: a review

In this paper we provide a broad introduction to the topic of computer experiments. We begin by briefly presenting a number of applications with different types of output or different goals. We then review modelling strategies, including the popular Gaussian process approach, as well as variations and modifications. Other strategies that are reviewed are based on polynomial regression, non-parametric regression and smoothing spline ANOVA. The issue of multi-level models, which combine simulators of different resolution in the same experiment, is also addressed. Special attention is given to modelling techniques that are suitable for functional data. To conclude the modelling section, we discuss calibration, validation and verification. We then review design strategies including Latin hypercube designs and space-filling designs and their adaptation to computer experiments. We comment on a number of special issues, such as designs for multi-level simulators, nested factors and determination of experiment size.     

Utilitarianism and discrimination

Since Becker (1971), a common argument against asymmetric norms that promote minority rights over those of the majority is that such policies reduce total welfare. While this may be the case, we show that there are simple environments where aggregate sum of individual utilities is actually maximized under asymmetric norms that favor minorities. We thus maintain that without information regarding individual utilities one cannot reject or promote segregation-related policies based on utilitarian arguments.     

Parents Differentiate Between Their Personal Values and Their Socialization Values: The Role of Adolescents' Values

This study focuses on the differentiation process, involving the emergence of a distinction between parents' own personal values and their socialization values (the values they want their children to adopt), and on the contribution of children's values to their parents' socialization values. Measures of personal and socialization values were administrated to 603 Israeli adolescents and their parents. As we hypothesized, parents differentiate between their personal values and their socialization values. Moreover, adolescents' values had a specific contribution to their parents' socialization values. These findings provide new support to the notion that the socialization process should be considered as the result of the interaction between parents and their adolescent children rather than as a unidirectional process affected by parents alone.

Quantitative assessment of response shift in QOL research

Two assumptions which characterize the measurements of quality life (QOL) studies, are questioned by the present report: First, the assumption that QOL is the same thing for all subjects, is usually related to health problems and can easily be measured across subjects. Second, when this assumption is given up by introducing subjective base-rates in an intra-subject (before-after) design, researchers still tend to assume that no response shifts occur on the QOL scales, e.g., that these scales maintain the same meaning and values for subjects over time and interventions. In our study we found that QOL had different subjective interpretations [1--4]. While for some certain issues in their family-life determined their quality of life, for others these were issues at their workplace or of their health conditions. Second, when QOL was tested against a subjective base-line (for each individual according to their choices of domains), about eleven percent of the hypertensives and normotensives showed a clear response shift of scale-calibration over the period of one year. When the scores of these subjects were excluded, the significance of certain previously reported results changed. For example, the significant difference between normotensives and hypertensives concerning the change in their subjective evaluation of QOL over the year and their initial depression became more significant, while similar changes in their evaluation of sexual impairment and control at their work-place became insignificant. These results suggest that response shifts have to be traced and quantified, before one can claim any results (or lack of results) in 'before-after' designs, concerning subjective meaningful issues like quality of life.     

The Endowment Effect on Academic Chores Trade-Off (ACTO)

The present study aimed to investigate three questions concerning Kahneman’s Endowment Effect. (a) Does the Endowment Effect apply to negotiations on intangible items such as intellectual resources and time invested in academic chores? (b) Does the sequence in which proposals are presented to the negotiators influence the Endowment Effect and, if so, how? (c) Does the Endowment Effect have the same impact in on-going negotiations as in one-shot negotiations? The investigation focused on the trade-off made by students between advanced courses and seminars, which we term as Academic Chores Trade-Off (ACTO). The results indicated the existence of the Endowment Effect in negotiations on the above intangible items (ACTO) but could also be partially interpreted as reflecting the negotiators attempts to improve their positions. The results also supported the existence of a Sequence Effect combined with an intensification of the Endowment Effect. The Endowment Effect in on-going negotiations was not found to be significantly different from that in the one-shot format.     

Utilitarian Preferences With Multiple Priors

This paper proposes a method for aggregating individual preferences in the context of uncertainty. Individuals are assumed to abide by Savage's model of Subjective Expected Utility, in which everyone has his/her own utility and subjective probability. Disagreement on probabilities among individuals gives rise to uncertainty at the societal level, and thus society may entertain a set of probabilities rather than only one. We assume that social preference admits a Maxmin Expected Utility representation. In this context, two Pareto‐type conditions are shown to be equivalent to social utility being a weighted average of individual utilities and the social set of priors containing only weighted averages of individual priors. Thus, society respects consensus among individuals' beliefs and does not add ambiguity beyond disagreement on beliefs. We also deal with the case in which society does not rule out any individual belief.     

Attitudes towards judicial review in Japan and South Korea: indications for the existence of a liberal-democratic civic culture

Though very close geographically and culturally, postwar Japan and the Republic of Korea – both non-classical Western democracies – each experienced a very different democratization process and adopted a different kind of democratic regime. This is strongly expressed in the form of their judicial review mechanisms that are aimed in different ways at assisting citizens in encouraging the courts to review laws and policies. Given this backdrop, through the analysis of the attitudes of the Japanese and Korea's citizens to their judicial review mechanisms we search for civic attitudes in these societies. By doing so, we try to contribute to the great debate regarding the capability of non-Western societies that did not develop from a well-rooted liberal culture to adopt and internalize liberal-democratic values.
