Collective Coercion

When a collective-choice situation places coercive pressure on individual participants, the law’s traditional protection of individual autonomy against coercion must be reconciled with its necessary role in resolving problems of collective action. On the one hand, the law might seek to remove coercion from the equation so that individuals are free to make their own decisions. On the other hand, the law might empower a central authority to decide, thereby solving a problem of collective action in order to maximize the group’s shared interests. The tension between these two approaches creates deep uncertainty for the regulation of collective-choice situations. It is palpable in the law’s conflicted response to corporate takeover bids in that applicable federal and state laws simultaneously enhance and diminish shareholder choice. Elsewhere—for example, the structure of government buyout programs, or the imposition of mandatory fees for nonunion employees—the intersection of coercion and collective choice may be overlooked altogether. By situating the literature on coercion in the context of offers that exploit collective-action problems, this Article proposes a unifying framework for identifying and remedying problems of collective coercion

Scaffolding School Pupils’ Scientific Argumentation with Evidence-Based Dialogue Maps

This chapter reports pilot work investigating the potential of Evidence-based Dialogue Mapping to scaffold young teenagers’ scientific argumentation. Our research objective is to better understand pupils’ usage of dialogue maps created in Compendium to write scientific ex-planations. The participants were 20 pupils, 12-13 years old, in a summer science course for “gifted and talented” children in the UK. Through qualitative analysis of three case studies, we investigate the value of dialogue mapping as a mediating tool in the scientific reasoning process during a set of learning activities. These activities were published in an online learning envi-ronment to foster collaborative learning. Pupils mapped their discussions in pairs, shared maps via the online forum and in plenary discussions, and wrote essays based on their dialogue maps. This study draws on these multiple data sources: pupils’ maps in Compendium, writings in science and reflective comments about the uses of mapping for writing. Our analysis highlights the diversity of ways, both successful and unsuccessful, in which dialogue mapping was used by these young teenagers

Diffuse Atomic and Molecular Gas near IC443

We present an analysis of results on absorption from Ca II, Ca I, K I, and the molecules CH+, CH, C2, and CN that probes gas interacting with the supernova remnant IC443. The eleven directions sample material across the visible nebula and beyond its eastern edge. Most of the neutral material, including the diatomic molecules, is associated with the ambient cloud detected via H I and CO emission. Analysis of excitation and chemistry yields gas densities that are typical of diffuse molecular gas. The low density gas probed by Ca II extends over a large range in velocities, from -120 to +80 km/s in the most extreme cases. This gas is distributed among several velocity components, unlike the situation for the shocked molecular clumps, whose emission occurs over much the same range but as very broad features. The extent of the high-velocity absorption suggests a shock velocity of 100 km/s for the expanding nebula.Comment: To be published in Ap

The hullaballoo over e-learning? Technology and pluralism in economics

E-learning vs. “talk and chalk”: this binary opposition presents a conflict that has dominated existing pedagogical research. That technological innovation offers an alternative for pressured educationists to improve efficiency and question the cost-effectiveness of traditional teaching methods creates a false dichotomy. This paper addresses the influence of the erroneous “either/or” position and discards it. It claims that there is no fundamental antagonism between the two methods of instruction and proffers the alternative found in blended learning methods. The meticulous splicing of e-learning and traditional lectures liberates the Economics lecturer to deliver a pluralist perspective. Thus, technology becomes a vital tool enabling educators to escape from the limitation of monist teaching methods and guarantees that economics students can fully engage with the discipline’s vibrant debates. “Contest and controversy; orthodoxy and heterodoxy; critique and reject”: technology’s real role is to facilitate a workable space for the free thinking mind

Efficacy of Online Training for Improving Camp Staff Competency

Preparing competent staff is a critical issue within the camp community. This quasi-experimental study examined the effectiveness of an online course for improving staff competency in camp healthcare practices among college-aged camp staff and a comparison group (N = 55). We hypothesized that working in camp would increase competency test scores due to opportunities for staff to experientially apply knowledge learned online. Hierarchical linear modeling was used to analyse the cross-level effects of a between-individuals factor (assignment to experimental or comparison group) and within-individual effects of time (pre-test, post-test #1, and post-test #2) on online course test scores. At post-test #2, the difference in average test scores between groups was ~30 points, with the treatment group scoring lower on average than the comparison group. Factors that may have influenced these findings are explored, including fatigue and the limited durability of online learning. Recommendations for research and practice are discussed

Face-to-face: Social work and evil

The concept of evil continues to feature in public discourses and has been reinvigorated in some academic disciplines and caring professions. This article navigates social workers through the controversy surrounding evil so that they are better equipped to acknowledge, reframe or repudiate attributions of evil in respect of themselves, their service users or the societal contexts impinging upon both. A tour of the landscape of evil brings us face-to-face with moral, administrative, societal and metaphysical evils, although it terminates in an exhortation to cultivate a more metaphorical language. The implications for social work ethics, practice and education are also discussed

Watching me watching you: Black women in Britain on YouTube

YouTube and video bloggers (vloggers) have been a source of academic interest, yet few studies explore the representation or experiences of Black women on YouTube. The video blogs (vlogs) of Black women yield symbolic digital resources which young Black women may engage with in self-exploratory, self-educating, resistant and collective ways. This article reflects on 21 in-depth interviews with young Black women in Britain, aged 19–33 years. It addresses how their engagement with Black women’s vlogs intersects with identity and ideological work, including participation in Black digital diasporic dynamics. Influenced by research about Black women and media culture, resistant YouTube activity, as well as race and everyday uses of celebrity, this article explores the YouTube usage of young Black women in Britain, while reflecting on what this reveals about their lives in the early 21st century. This article forms part of ‘On the Move’, a special issue marking the twentieth anniversary of the European Journal of Cultural Studies

Phase I dose-escalation trial of the oral AKT inhibitor uprosertib in combination with the oral MEK1/MEK2 inhibitor trametinib in patients with solid tumors.

PurposeThis study aimed to determine the safety, tolerability, and recommended phase II doses of trametinib plus uprosertib (GSK2141795) in patients with solid tumors likely to be sensitive to MEK and/or AKT inhibition.MethodsThis was a phase I, open-label, dose-escalation, and dose-expansion study in patients with triple-negative breast cancer or BRAF-wild type advanced melanoma. The primary outcome of the expansion study was investigator-assessed response. Among 126 enrolled patients, 63 received continuous oral daily dosing of trametinib and uprosertib, 29 received various alternative dosing schedules, and 34 were enrolled into expansion cohorts. Doses tested in the expansion cohort were trametinib 1.5 mg once daily (QD) + uprosertib 50 mg QD.ResultsAdverse events (AEs) were consistent with those reported in monotherapy studies but occurred at lower doses and with greater severity. Diarrhea was the most common dose-limiting toxicity; diarrhea and rash were particularly difficult to tolerate. Overall, 59% and 6% of patients reported AEs with a maximum severity of grade 3 and 4, respectively. Poor tolerability prevented adequate delivery of uprosertib with trametinib at a concentration predicted to have clinical activity. The study was terminated early based on futility in the continuous-dosing expansion cohorts and a lack of pharmacological or therapeutic advantage with intermittent dosing. The objective response rate was < 5% (1 complete response, 5 partial responses).ConclusionsContinuous and intermittent dosing of trametinib in combination with uprosertib was not tolerated, and minimal clinical activity was observed in all schedules tested

Medium modification of jet fragmentation in Au+Au collisions at sqrt(s_NN)=200 GeV measured in direct photon-hadron correlations

The jet fragmentation function is measured with direct photon-hadron correlations in p+p and Au+Au collisions at sqrt(s_NN)=200 GeV. The p_T of the photon is an excellent approximation to the initial p_T of the jet and the ratio z_T=p_T^h/p_T^\gamma is used as a proxy for the jet fragmentation function. A statistical subtraction is used to extract the direct photon-hadron yields in Au+Au collisions while a photon isolation cut is applied in p+p. I_ AA, the ratio of jet fragment yield in Au+Au to that in p+p, indicates modification of the jet fragmentation function. Suppression, most likely due to energy loss in the medium, is seen at high z_T. The fragment yield at low z_T is enhanced at large angles. Such a trend is expected from redistribution of the lost energy into increased production of low-momentum particles.Comment: 562 authors, 70 insitutions, 8 pages, and 3 figures. Submitted to Phys.
