Homo machinus versus Homo sapiens: A knowledge management perspective of virtual communities in cyberspace

Abstract

Amidst debates on whether virtual communities can exist as a solution to technological developments, evidence suggests that knowledge creation and sharing are symptomatic of Home sapiens which may develop into idiosyncratic Homo machinus in cyberspace. According to Geyer (1996, 60), the communication revolution, backed up by accelerating technological development, has created a substructure for the emergence of virtual communities. Recent writings on virtual communities acknowledge Knowledge management as the most often used strategy to bring the human side into the equation. Enabled by online interactive communication technologies, this strategy allows virtual communities to create and share knowledge across the globe, thereby creating a global knowledge-based virtual reality in cyberspace. This article is essentially a theoretical discussion of virtual communities in cyberspace from a knowledge management perspective.     

House poor in Los Angeles: examining patterns of housing-induced poverty by race,nativity, and legal status

Housing affordability in the United States is generally operationalized using the ratio approach, with those allocating more than thirty percent of income to shelter costs considered to have housing affordability challenges. Alternative standards have been developed that focus on residual income, whether income remaining after housing expenditures is sufficient to meet non-housing needs. This study employs Los Angeles Family and Neighborhood Survey data to consider racial/ethnic, nativity and legal status differences in one residual income standard. Logistic regression analyses of housing-induced poverty focus on whether there are differences among five distinct groups: US born Latinos, Non-Hispanic Whites, and African Americans, authorized Latino immigrants, and unauthorized Latino immigrants. Results suggest that: (1) Latino natives are significantly more likely to be in housing-induced poverty than African Americans and Latino immigrants, and (2) unauthorized Latino immigrants are not more likely to experience the outcome than other groups. The present work extends previous research. First, the results provide additional evidence of the value of operationalizing housing affordability using a residual income standard. Alternatives to the ratio approach deserve more empirical attention from a wider range of scholars and policymakers interested in housing affordability. Second, housing scholarship to date generally differentiates among Latinos by ethnicity, nativity, and citizenship. The present study contributes to emerging research investigating heterogeneity among Latinos by nativity and legal status.     

Qiagen's Investigator™ Quantiplex Kit as a Predictor of STR Amplification Success from Low‐Yield DNA Samples,

Qiagen's Investigator? Quantiplex kit, a total human DNA quantitation kit, has a 200‐base pair internal control, fast cycling time, and scorpion molecules containing a covalently linked primer, probe, fluorophore, and quencher. The Investigator? Quantiplex kit was evaluated to investigate a value under which complete short tandem repeat (STR) failure was consistently obtained. Buccal swabs were extracted using the Qiagen QIAamp^® DNA Blood Mini Kit, quantified with the Investigator? Quantiplex kit using a tested half‐volume reaction, amplified with the ABI AmpFlSTR^® Identifiler kit, separated on the 3100Avant Genetic Analyzer, and data analyzed with GeneMapper^® ID v.3.2. While undetected samples were unlikely to produce sufficient data for statistical calculations or CODIS upload (2.00 alleles and 0.82 complete loci on average), data may be useful for exclusionary purposes. Thus, the Investigator? Quantiplex kit may be useful for predicting STR success. These findings are comparable with previously reported data from the Quantifiler? Human kit.     

Social Networks and Social Control of Probationers with Co-Occurring Mental and Substance Abuse Problems

Probationers with co-occurring mental and substance abuse problems (PCPs) are both subject to considerable social control, and at high risk of probation failure. In this study, we screened 601 probationers for symptoms, interviewed 82 identified PCPs about their relationships, and then followed these PCPs for eight months to record treatment nonadherence and other probation violations. First, PCPs’ social networks were small, heavily comprised of professionals and opposing forces who engaged in risky behavior, and saturated with pressure to adhere to treatment. Second, the size and composition of PCPs’ social networks were more relevant to rule compliance than social support and undermining. Third, the quality of PCPs’ relationships was key: satisfying relationships with clinicians and, to a lesser extent, officers and the core network related to low perceived coercion, high treatment adherence, and low risk of future violations. In particular, having a likable clinician who engaged in participatory decision-making reduced the risk of violations. Implications for contextually sensitive risk reduction efforts are discussed.     

A model of cross-cultural training in the transfer of technology

During the past few decades, many aspects of the transfer of technology from developed to less-developed countries have been examined in detail. Although much of the transfer has been done by transnational corporations (TNCs), one area that has received scant attention in the literature is the cross-cultural training of workers in the host country. A model is developed to show how critical training the worker is to the success of the TNC in the host country. This model emphasizes the need for workers to be trained to understand and use the new (foreign) technology and to understand the culture of the foreign corporation. Thomas S.

`Subjects' of Regulation/Resistance? Postmodern Feminism and Agency in Abortion-Decision-Making

This article explores the epistemological and strategic issues facing feminists embarking upon narrative explorations into women's experiences. It considers the implications for feminist epistemology of acknowledging women's participation in dominant ideologies about their social role. Focusing upon questions of women's agency, it asks how this `conforming knowledge' might complicate postmodernist feminist notions of resisting and reconstructing law's categorisation of `Woman'. It also represents an attempt to clarify, in advance of my own analysis of women's agency in abortion decision-making, why postmodern feminists might talk to women – the `subjects' of law's constructive power. It seeks additionally to open a discussion among a wider audience of feminists about what we might do with the information uncovered through listening to women's own stories in an area pronounced upon authoritatively by a multitude of discourses.
