Evaluation of selected ergonomic assessment tools for use in providing job accommodation for people with inflammatory arthritis

Inflammatory arthritis (IA) is a leading cause of work disability, especially for those with jobs involving repetitive, hand-intensive or manual work. Ergonomic interventions may mediate against job loss. Our objective was to identify desirable features of an ergonomic tool for use in providing job accommodation for people with IA, and to evaluate a selection of ergonomic and rehabilitation tools against these features. Eight desirable features were compared across 16 assessment tools. None of the tools met all the pre-determined features. Ergonomic assessment tools should incorporate objective assessment of risk factors together with subjective perceptions of symptom aggravation, and identify risk factors that may not currently be causing problems, but may increase risk of aggravation or injury in the future. To accommodate the needs of people with IA, the tool should allow for evaluation of risks and generation of solutions without a worksite visit in situations where the client does not want to disclose their illness. Finally, an assessment tool needs to be applicable to a wide range of worksites, easy to use, valid, and reliable. Against these criteria, it appears that there is a lack of appropriate ergonomic assessment tools for use in people with IA.     

Use of Environmental Tobacco Smoke Constituents as Markers for Exposure

The 16-City Study analyzed for gas-phase environmental tobacco smoke (ETS) constituents (nicotine, 3-ethenyl pyridine [3-EP], and myosmine) and for particulate-phase constituents (respirable particulate matter [RSP], ultraviolet-absorbing particulate matter [UVPM], fluorescing particulate matter [FPM], scopoletin, and solanesol). In this second of three articles, we discuss the merits of each constituent as a marker for ETS and report pair-wise comparisons of the markers. Neither nicotine nor UVPM were good predictors for RSP. However, nicotine and UVPM were good qualitative predictors of each other. Nicotine was correlated with other gas-phase constituents. Comparisons between UVPM and other particulate-phase constituents were performed. Its relation with FPM was excellent, with UVPM approximately 1 1/2 times FPM. The correlation between UVPM and solanesol was good, but the relationship between the two was not linear. The relation between UVPM and scopoletin was not good, largely because of noise in the scopoletin measures around its limit of detection. We considered the relation between nicotine and saliva cotinine, a metabolite of nicotine. The two were highly correlated on the group level. That is, for each cell (smoking home and work, smoking home but nonsmoking work, and so forth), there was high correlation between average cotinine and 24-hour time-weighted average (TWA) nicotine concentrations. However, on the individual level, the correlations, although significant, were not biologically meaningful. A consideration of cotinine and nicotine or 3-EP on a subset of the study whose only exposure to ETS was exclusively at work or exclusively at home showed that home exposure was a more important source of ETS than work exposure.     

基于期望效用-熵模型的基金评级方法及其在中国基金评级中的应用

基金评级对于投资者来说具有重要的参考价值,研究合适的基金评级方法非常必要。本文针对晨星评级对风险调整和预测能力不足的特征,研究应用期望效用-熵（EU-E）模型基金评级方法对我国开放式基金进行评级的预测能力;并以Sharpe指数、Jensen、Fama-French三因素和Carhart四因素α作为业绩指标,利用固定效应面板数据回归模型对期望效用-熵模型和随机效应面板数据回归模型对晨星基金评级的预测能力进行比较分析。采用样本期由2011年2月到2016年6月的261只基金为研究样本进行评级;研究结果表明,基于期望效用-熵平衡系数λ=0.25和0.75时,EU-E模型基金评级方法评级具有良好的预测能力,而晨星评级预测能力较弱。特别地,λ=0.25和0.75时,EU-E模型评级的五星级基金业绩优于晨星评级对应的基金业绩,而且相比于晨星评级可以更好地区分不同星级基金的业绩。另外,研究结论对于短期、中期和长期的样本都是稳健的。     

Why Dora Left: Freud and the Master Discourse

The question of why Dora left her treatment before it was brought to a satisfactory end and the equally important question of why Freud chose to publish this problematic and fragmentary story have both been dealt with at great length by Freud’s successors. Dora has been read by analysts, literary critics, and not least by feminists.

The aim of this paper is to point out the position Freud took toward his patient. Dora stands out as the one case among Freud’s 5 great case stories that has a female protagonist, and reading the case it becomes clear that Freud stumbled because of an unresolved problem toward femininity, both Dora’s and his own. In Dora, it is argued, Freud took a new stance toward the object of his investigation, speaking from the position of the master. Freud presents himself as the one who knows, in great contrast to the position he takes when unraveling the dream. Here he is the humble scholar giving evidence of a great tolerance for not-knowing. These 2 positions run through Freud’s writings from “The Interpretation of Dreams” (1900b) to “Analysis Terminable and Interminable” (1937a). From the Dora case a line can be drawn to Freud’s metaphor of the bedrock of castration, the unsurpassable barrier to both analytical work and the theory of sex and gender.     

“Never enough hours in the day”: Employed mothers’ perceptions of time pressure

Finding sufficient time to meet work and family commitments poses immense challenges for employed mothers in 21st century contemporary life. Understanding how employed women with children manage their finite time resources requires deeper investigation of how time pressures accrue across work and home contexts. This study draws on data from in‐depth interviews with 18 working mothers from diverse occupations (professional, sales, service, clerical, technical and trades) and across a range of employment hours (full and part‐time). The findings from this study show that employed mothers endure high levels of time pressure related to time poverty (insufficient time for necessary or discretionary activities), time intensity (multitasking and merging work and home boundaries) and time density (familial emotion and organisation work). When women use strategies to increase time efficiency, it does not necessarily reduce their perceptions of time pressure. Juggling multiple tasks simultaneously distorts women's temporal experiences and diminishes the quality of time. Workplaces and policymakers need to find better ways to encourage employed fathers to share the responsibility for home‐ and family‐related care and organisational work. Such measures may reduce the time stress and time inequity women endure, particularly in the time management control centre of the home.     

Group Cohesion and Homework Adherence in Multi‐Family Group Therapy for Schizophrenia

This study examined the relationship between levels of group cohesion, defined as whole group relationships, and between‐session therapeutic homework adherence in a multi‐family group therapy (MFGT) for people with schizophrenia. Participants from 18 consenting families attending MFGT groups completed weekly homework adherence ratings, group cohesion and spontaneous between‐session activity measures. Levels of group cohesion at each session were compared with measures of scheduled and spontaneous homework adherence reported at the next session. It was hypothesised that higher levels of group cohesion would be related to homework adherence and other spontaneous between‐session therapeutic activity completed by group members. Results show higher levels of group cohesion were associated with higher rates of spontaneous between‐session therapeutic activity. However, contrary to expectations no significant relationship between cohesion and scheduled homework completion was found. The implications of the findings for group processes and homework adherence are discussed.     

Linking human factors to corporate strategy with cognitive mapping techniques

For human factors (HF) to avoid being considered of "side-car" status, it needs to be positioned within the organization in such a way that it affects business strategies and their implementation. Tools are needed to support this effort. This paper explores the feasibility of applying a technique from operational research called cognitive mapping to link HF to corporate strategy. Using a single case study, a cognitive map is drawn to reveal the complex relationships between human factors and achieving an organization's strategic goals. Analysis of the map for central concepts and reinforcing loops enhances understanding that can lead to discrete initiatives to facilitate integration of HF. It is recommended that this technique be used with senior managers to understand the organizations` strategic goals and enhance understanding of the potential for HF to contribute to the strategic goals.
