Distribution of Arsenic and Copper in Sediment Pore Water: An Ecological Risk Assessment Case Study for Offshore Drilling Waste Discharges

Due to the hydrophobic nature of synthetic based fluids (SBFs), drilling cuttings are not very dispersive in the water column and settle down close to the disposal site. Arsenic and copper are two important toxic heavy metals, among others, found in the drilling waste. In this article, the concentrations of heavy metals are determined using a steady state "aquivalence-based" fate model in a probabilistic mode. Monte Carlo simulations are employed to determine pore water concentrations. A hypothetical case study is used to determine the water quality impacts for two discharge options: 4% and 10% attached SBFs, which correspond to the best available technology option and the current discharge practice in the U.S. offshore. The exposure concentration ( C_E ) is a predicted environmental concentration, which is adjusted for exposure probability and bioavailable fraction of heavy metals. The response of the ecosystem  ( R_E )  is defined by developing an empirical distribution function of predicted no-effect concentration. The pollutants' pore water concentrations within the radius of 750 m are estimated and cumulative distributions of risk quotient  ( RQ = C_E / R_E )  are developed to determine the probability of RQ greater than 1.     

Talking about Beauty: A Study of Everyday Aesthetics among Low‐Income Citizens of Milan

This paper reports on research undertaken into the aesthetics of the everyday. As well as the subject matter of aesthetic philosophy, art criticism and of the sociology of art, beauty, and beautiful are of course very ordinary matters too. To shed light on the meanings of beauty as used in everyday settings and in natural language, we use the data collected in a study conducted with a group of low‐income residents of the city of Milan. In this study we were interested in analyzing their lifestyle in terms of their relationship with aesthetics, i.e., with “beautiful” objects and/or experiences. Participants' self‐reported aesthetic appreciations suggest that conceptions of “beauty” are used as devices to narrate pieces of identity, memories, experiences, etc. Their aesthetic judgements take on an anthropological function, creating a framework of meanings that help the participants make sense of the world of objects and of their own lives with/through them.     

纳粹屠杀与南京暴行的研究:范式转变与比较启示

相对于第二次世界大战期间侵华日军南京暴行,纳粹屠杀的研究成果更为丰富、多样和体系化,研究范式经历了从极权主义到结构主义,再到魅力权威的转变.这一转变将加害者从希特勒及纳粹领导层扩展到整个德国社会,进而产生了颠覆性的结果,即第三帝国的犯罪不仅是大规模受害者意义上的大,而且还在于参与者的多;这一转变还揭示纳粹屠杀的受害者不仅仅是犹太人,还包括境内外大量的非犹太人.这一事实表明除了反犹主义外,第三帝国的系列意识形态信条,如民族主义、殖民主义等构造了众多德国人愿意参与纳粹犯罪的条件.民族主义的心态和认同导致了受害者和加害者之间共有的人性感的降低,进而导致后者的道德标准的丧失;殖民活动与种族上的他者的出现使优越感和轻蔑的态度盛行,这些心态提供了纳粹屠杀和南京暴行比较研究的重要起点,而殖民地经历及暴力制度文化则是比较研究的重要内容.     

Perception of job satisfaction, service effectiveness and burnout among Arab social workers in Israel

Over the past three decades, the topics of job satisfaction and burnout have become a major focus of interest in research and professional training in the field of social work. However, there is a serious lack of studies focusing on these issues in the context of Arab social workers in Israel. This paper presents the results obtained from a subsample of Arab participants in a national study of Israeli social workers. It focuses on the correlations between several career outcomes and organizational conditions such as role characteristics, work conditions, job mastery, and power. Challenge at work and job mastery were found to be the most significant and consistent predictors of the outcome results. The implications of the results are also discussed.     

How Effective is Peer Education in Addressing Young People’s Sexual and Reproductive Health Needs in Developing Countries?

This review article questions the assumptions at the core of peer education interventions adopted in young people’s sexual and reproductive health programmes in developing countries. Peer education is a more complex and problematic approach than its popularity with development agencies and practitioners implies. Its rise to prominence is more indicative of the desire to find effective tools to address the HIV/AIDS pandemic, than of peer education’s proven effectiveness. The often simplistic model of social relations that underlies peer education interventions leads to the reinforcement of gendered power relations, and a failure to take account of the social dynamics of poverty. The dominant rationales for peer education are examined and contested. In spite of the mismatch between rhetoric and experience, the appeal of the approach remains powerful, stemming largely from the objective of engaging young people in health interventions in a way that increases their autonomy and capacity .     

The bothersome details of the world: Richard Byrd,Little America,and the problem of retreat

Abstract

In 1934, Admiral Richard E. Byrd retreated from his crew at the remote Little America encampment in Antarctica to an even more isolated setting: a small underground shack on ‘the dark immensity of the Ross Ice Barrier, on a line between Little America and the South Pole’. Byrd remained there in solitude for a little over four months and later wrote about his ordeal in Alone. This essay considers Byrd’s account alongside his earlier Antarctic writings in order to ask what they reveal about the difficulties of retreating and maintaining critical distance from ‘civilisation’.     

The Future Lives of Sociology Graduates

After earning a bachelor's degree, the fate of sociology undergraduates is mysterious. We know little about how many Canadians have sociology degrees and even less about what they do after graduation. Using a variety of data sources from Statistics Canada, we paint a historical portrait of the discipline by charting how many people, and who, become sociologists. We also examine where they are employed, how much they earn, and how satisfied they are with their degrees. Our findings show that sociology graduates are competitive with other fields of study on both wages and employment, but are less satisfied with their degrees. We stress how the discipline would be wise to pay more attention to our graduates and their opportunities. Nous en savons peu sur l'avenir et le nombre de Canadiens ayant des diplômes de sociologie et encore moins ce qu'ils font après la graduation. Grâce à des données de Statistiques Canada, nous dressons un portrait historique de la discipline en montrant combien de personnes, et quel genre de personnes, deviennent sociologues. Nous examinons aussi où ils travaillent, combien ils gagnent et leur niveau de satisfaction par rapport à leurs diplômes. Nos résultats démontrent que les gradués en sociologie sont compétitifs par rapport aux autres champs d’étude en termes de salaire et de taux d'emploi, mais qu'ils sont moins satisfaits de leurs diplômes. Nous notons que la discipline aurait intérêt à porter plus d'attention sur les gradués et leurs opportunités.     

A study of grouped failure time data and the misapplication of recurrent event modeling

Clinical trials often assess whether or not subjects have a disease at predetermined follow-up times. When the response of interest is a recurrent event, a subject may respond at multiple follow-up times over the course of the study. Alternatively, when the response of interest is an irreversible event, a subject is typically only observed until the time at which the response is first detected. However, some recent studies have recorded subjects responses at follow-up times after an irreversible event is initially observed. This study compares how existing models perform when failure time data are treated as recurrent events.
