Analysis of the implementation of ergonomic design at the new units of an oil refinery

Ergonomic design is the adaptation of working conditions to human limitations and skills in the physical design phase of a new installation, a new working system, or new products or tools. Based on this concept, the purpose of this work was to analyze the implementation of ergonomic design at the new industrial units of an oil refinery, using the method of Ergonomic Workplace Assessment. This study was conducted by a multidisciplinary team composed of operation, maintenance and industrial safety technicians, ergonomists, designers and engineers. The analysis involved 6 production units, 1 industrial wastewater treatment unit, and 3 utilities units, all in the design detailing phase, for which 455 ergonomic requirements were identified. An analysis and characterization of the requirements identified for 5 of the production units, involving a total of 246 items, indicated that 62% were related to difficult access and blockage operations, while 15% were related to difficulties in the circulation of employees inside the units. Based on these data, it was found that the ergonomic requirements identified in the design detailing phase of an industrial unit involve physical ergonomics, and that it is very difficult to identify requirements related to organizational or cognitive ergonomics.     

Cognitive behavioral interventions for depression among Hispanic people: promising meta-analytic evidence for deep cultural adaptations

ABSTRACT

Depressive disorders are common among Hispanic people. Evidence-informed guidelines indicate cognitive behavioral interventions (CBI), but they were developed primarily with non-Hispanic White people. Narrative studies of clients and workers along systematic review evidence suggested that well-defines cultural adaptations of CBIs would likely improve outcomes among Hispanics people with diverse mental health problems. We advanced the meta-analytic hypothesis that CBIs incorporating so-called “deep structure” cultural adaptations will be more effective than otherwise similar, but more superficially, “surface structure” or non-adapted interventions with depressed Hispanic people. This meta-analysis synthesized evidence from nine typically randomized trials in the United States with one subsample from the Commonwealth of Puerto Rico. Most clients were young women, living in poverty and suffering a reactive depressive episode. We found statistical and practical support for our hypothesis. In most practice contexts, CBI success rates were between 15% and 30% better than those typically observed with other usual practices. Moreover, these effects were maintained at 6- to 12-month follow-up. Given the size and growth of the Hispanic American population, their prevalent experience of depression, and the size of the intervention effects, these synthesized findings seem of potentially great human, clinical, and policy significance.     

A Life-course Perspective on the "Gateway Hypothesis"

Drawing on stress and life-course perspectives and using panel data from 1,286 south Florida young adults, we assess three critical questions regarding the role of marijuana in the "gateway hypothesis." First, does teen marijuana use independently (causally) affect subsequent use of more dangerous substances? Second, if so, does that effect apply to the abuse of other illicit substances, as defined by the DSM-IV, or only to the use of such substances? Finally, does any causal effect of teen marijuana use survive beyond adolescence, or is it a short-term effect that subsides as adolescents transition to adulthood? Our results indicate a moderate relation between early teen marijuana use and young adult abuse of other illicit substances; however, this association fades from statistical significance with adjustments for stress and life-course variables. Likewise, our findings show that any causal influence of teen marijuana use on other illicit substance use is contingent upon employment status and is short-term, subsiding entirely by the age of 21. In light of these findings, we urge U.S. drug control policymakers to consider stress and life-course approaches in their pursuit of solutions to the "drug problem."     

Important Risk Factors in Home-Removal Decisions: Social Caseworker Perceptions

The current study identified factors that played a significant role in decisions to separate a child from his/her primary caretakers for 51 social service caseworkers. Participants rated and ranked the importance of 35 child risk/well-being factors used in recent child separation dispositions. Results indicated that boundary setting with a perpetrator of abuse and parental motivation played a significant role in decision-making. These preliminary findings suggest the need to prioritize services aimed at the promotion of the non-maltreating parent’s limit setting with the perpetrator of abuse, as well as caretaker motivation/cooperation.Virginia M.

Education for Cross-Cultural Social Work Practice

Abstract

Little attention has been given to the needs of international and American social work students who are preparing for direct practice outside of the United States. A preliminary model of cross-cultural social work practice is described as the basis for a course in direct social work practice in international settings.     

Food Expensiveness in Scotland's Remote Areas: An Analysis of Household Food Purchases☆

The purpose of this paper is to investigate whether consumers in Scotland's remote areas suffer from food prices that are higher than the average national prices (i.e., whether a “remoteness premium” exists). The question has been raised by several organizations in those communities looking at the high prices in local stores. This paper provides a new perspective using actual purchasing prices of a sample of 5,252 households in Scotland for 2017 and 2018. In this way, households' ability to shop for lower prices is considered, unlike in previous studies. An expensiveness index was computed to measure the expensiveness of food at household level and control for differences in quality. It showed that consumers in remote areas pay a small premium (0.3 to 0.4 percent) with respect to average prices, which is statistically significant but economically not relevant. To understand the effect of several factors, AHEI was regressed on a number of explanatory variables including local area characteristics and household demographics and consumers' shopping strategy. The results were used to simulate three hypothetical scenarios related to impact of changes in the population's age, access to discount stores, and social deprivation on food expensiveness.
