Open Source Software Collaboration: Foundational Concepts and an Empirical Analysis

This paper has three primary goals. First, we provide an overview on some foundational concepts – “peer-production,” “user-centric innovation,” “crowdsourcing,” “task granularity,” and yes, open source and open content – for they are key elements of Internet-based collaboration we see today. Second, through this discussion on foundational concepts, we hope to make it clear why people interested in collaborative public management and administration should care about open source and open source-like collaboration. After this argument is made, we provide a very condensed summary of where we are to date on open source collaboration research. The goal of that research is to learn about the factors that lead to successful or abandoned collaborations in the open source domain, in part to help us understand how “open source-like” collaborations can be deployed in areas outside of software. We have a lot to cover. Let’s get right to it

Prescribing as affective clinical practice: Transformations in sexual health consultations through HIV pre-exposure prophylaxis

New medicines can transform routines and priorities in clinical practice, but how do clinicians think and feel about these changes, and how does it affect their work? In Australia, the HIV prevention regimen pre-exposure prophylaxis (PrEP) has been rapidly rolled out, transforming the sexual cultures and practices of users, but less attention has been given to the ways PrEP has reconfigured clinical practice. This paper draws on 28 qualitative semi-structured interviews conducted between 2019 and 2020 with PrEP-providing doctors and nurses in Australia to consider how they have affectively engaged with PrEP and put it into practice. Through a reflexive thematic analysis, we explore how clinicians adapted to PrEP, how the field of HIV prevention has been transformed, and how these developments have changed how clinicians approach patients. While the introduction of PrEP was initially received with uncertainty and shock, clinicians described PrEP as enjoyable to prescribe, and better aligned with the moral duties of sexual health consultations than existing HIV prevention strategies like condoms. Through approaching clinical work as an ‘affective practice’, we argue for attending not only to how new interventions change expectations and practices, but also how these changes are felt and valued by clinicians

Ethical considerations in determining standard of prevention packages for HIV prevention trials: Examining PrEP

The successful demonstration that antiretroviral (ARV) drugs can be used in diverse ways to reduce HIV acquisition or transmission risks – either taken as pre-exposure prophylaxis (PrEP) by those who are uninfected or as early treatment for prevention (T4P) by those living with HIV – expands the armamentarium of existing HIV prevention tools. These findings have implications for the design of future HIV prevention research trials. With the advent of multiple effective HIV prevention tools, discussions about the ethics and the feasibility of future HIV prevention trial designs have intensified. This article outlines arguments concerning the inclusion of newly established ARV-based HIV prevention interventions as standard of prevention in HIV prevention trials from multiple perspectives. Ultimately, there is a clear need to incorporate stakeholders in a robust discussion to determine the appropriate trial design for each study population

Literary and cinematic perspectives on gender studies

This project focuses on gender studies including women, men, and sexual diversity studies. Students explore gender and sexuality in the fields of literature and cinema related to cultural, social, and economic issues in Latin America and Spain. The analysis includes a diverse selection of topics: gender and science, gender and sexuality, gender and minority ethnicities, feminism and diversity, transgender identities, transgender healthcare, lesbian and gay figures and trends, and intersex and culture

Nuclear criticality safety calculations for a K-25 site vacuum cleaner

A modified Nilfisk model GSJ dry vacuum cleaner is used throughout the K-25 Site to collect dry forms of highly enriched uranium (HEU). When vacuuming, solids are collected in a cyclone-type separator vacuum cleaner body. Calculations were done with the SCALE (KENO V.a) computer code to establish conditions at which a nuclear criticality event might occur if the vacuum cleaner was filled with fissile solution. Conditions evaluated included full (12-in. water) reflection and nominal (1-in. water) reflection, and full (100%) and 20% {sup 235}U enrichment. Validation analyses of SCALE/KENO and the SCALE 27-group cross sections for nuclear criticality safety applications indicate that a calculated k{sub eff} + 2{sigma} < 0.9605 may be considered safely subcritical. Thus, a system with a calculated k{sub eff} + 2{sigma} {ge} 0.9605 is considered unsafe and may be critical. Critical conditions were calculated to be 70 g U/L for 100% {sup 235}U and full 12-in. water reflection. This corresponds to a minimum critical mass of approximately 1,400 g {sup 235}U for the approximate 20.0-L volume of the vacuum cleaner. The actual volume of the vacuum cleaner is smaller than the modeled volume because some internal materials of construction were assumed to be fissile solution. The model was an overestimate, for conservatism, of fissile solution occupancy. At nominal reflection conditions, the critical concentration in a vacuum cleaner full of UO{sub 2}F{sub 2} solution was calculated to be 100 g{sup 235}U/L, or 2,000 g mass of 100% {sup 235}U. At 20% {sup 235}U for the 20.0-L volume of the vacuum cleaner. At 15% {sup 235}U enrichment and full reflection, critical conditions were not reached at any possible concentration of uranium as a uranyl fluoride solution. At 17.5% {sup 235}U enrichment, criticality was reached at approximately 1,300 g U/L which is beyond saturation at 25 C
