Cash-based interventions: lessons from southern Somalia

Commodity distributions, the predominant relief response, are subject to growing criticism, while donors and humanitarian actors are increasingly viewing cash-based interventions as a viable alternative. This paper aims to contribute to the current debate on cash-based interventions by drawing on the experience of Action Contre la Faim in southern Somalia, where it has implemented cash for work programmes since 2004. The authors conclude that cash-based interventions are a feasible option in complex emergencies as well as in highly insecure environments as long as appropriate modalities are employed and objectives are clearly set in accordance with the needs and the context. Cash as a relief response offers wide-reaching possibilities for the future from both the perspective of the donor/agency and the standpoint of the beneficiary. It enables the beneficiaries to take control of the relief themselves and to adapt it to their individual requirements in a timely manner.     

Worker-centered investigation of issues with procedural systems: Findings from interviews with a representative sample of workers in high-risk process industries

Issues related to procedural systems have been found to contribute to incidents in many high-risk industries such as petrochemical, oil and gas, etc. While previous research has focused on understanding issues with procedural systems from the perspective of the workers (who are the end-users of procedures), most of this research suffers from samples that only include companies with programs focused on improving safety by improving procedures. These companies may have inherent differences in their safety practices and thus the experiences of these workers may not completely represent all workers’ experiences in this domain. The purpose of this study is to gain insights into the thoughts and perceptions from a representative and broad sample of workers concerning procedure use and purpose. To improve the generalizability of previous findings, interviews were conducted with workers from a broad range of high-risk process industries to investigate issues related to procedure adherence that may be present in companies not currently implementing. Findings from a qualitative data analysis provide support for the generalizability of issues previously discovered, such as: more experience workers being more likely to deviate; procedure quality being inconsistent; and the procedure revision process being problematic. However additional prominent issues were found as well. Most importantly, this study found that adherence to procedures is often motivated by potential liability issues instead of genuine concerns for safety in organizations and many deviations from procedures were due to pressure from immediate supervisors. These findings suggest a relationship between the effectiveness/quality of procedural systems and the safety climate of the organization or work unit.

Need for recovery after emotional labor: Differential effects of daily deep and surface acting

This diary study examines the psychological processes that contribute to daily recovery from emotional labor by combining emotion regulation with work‐home resources theories. We hypothesized that overall perceptions of display rules relate positively to daily deep and surface acting. Daily surface acting was expected to relate positively to exhaustion and negatively to flow during work and consequently, to a higher need for recovery at the end of the workday. In contrast, daily deep acting was hypothesized to relate positively to flow and negatively to exhaustion and consequently, to a lower need for recovery at the end of the workday. In turn, need for recovery was expected to associate negatively to vigor at bedtime through reduced relaxation during leisure. Fifty Dutch and Polish employees first filled in a survey, and then a diary for five consecutive workdays, twice per day: at the end of the workday and before sleep. Multilevel path analyses largely supported these hypotheses suggesting that surface acting has unfavorable implications, whereas deep acting has favorable implications for daily well‐being at work and recovery after work.     

Evaluation of effect of different membership functions on risk assessment

This study aims to define the relationship between risk degrees and risk indexes on different functional structures with the assumption that risk degrees may not always present a linear relationship with the risk indexes. In this way, risk indexes suitable for expert evaluation of working conditions and computed using three different membership functions are determined. Among the membership functions used, one is preferred as linear and the others are preferred as non-linear. Additionally, a new fuzzy risk assessment (RA) algorithm is developed using these three membership functions. With this new fuzzy RA algorithm, a more flexible and precise process becomes available, while information loss during the determination of the risk index of danger sources is prevented. As a result, non-linear increasing membership function is selected as most suitable for the expression of the relationship between risk degrees and risk indexes.     

The effects of hand force variation on shoulder muscle activation during submaximal exertions

Upper limb injuries are highly prevalent in the workplace and new tools are needed to proactively design workstations to reduce injury risk. The objective was to characterize spatial, load and direction dependency of muscle activity for hand exertions in the upper limb workspace. Electromyographic signals were collected from 14 upper limb muscles during exertions for all combinations of 4 submaximal hand forces (20/30/50/60?N) in 6 cardinal (up/down/left/right/forward/backward) directions at 5 hand locations. Linear muscle activity increases accompanied increased hand forces. Total muscle activity increases between 20 and 60?N hand forces ranged by direction from 92% (downward) to 189% (right). Prediction equations for all muscles depended on hand force, and linear, quadratic and interaction permutations of hand location. Muscle activity associated with manual tasks is load, direction and spatially dependent. Equations developed to describe these complex relationships can be used to better design future and evaluate current occupational activities.     

生活垃圾填埋场空气中VOCs组成及年际变化

采用SUMMA罐采样-气相色谱-质谱法采集并分析了2006—2010年4、10月上海某生活垃圾填埋场及周边环境空气中挥发性有机物(VOCs)的种类和含量变化情况。结果表明,共检测出34种VOCs化合物,以单环芳烃、甲基乙基酮、卤代脂肪烃为主,其中19种化合物属于美国环保局重点控制的空气中有害污染物;填埋区作业面是填埋堆体内部VOCs释放的重要途径之一,其中甲基乙基酮、甲苯、乙苯、间/对-二甲苯对TVOCs质量浓度贡献率超过60%;生活垃圾填埋场及周边环境空气中TVOCs质量浓度年季变化较稳定,但同年度内秋季浓度高于春季。
