Ergonomic evaluation of processes and products in the manufacture of upholstery

This study aimed to perform an ergonomic evaluation of industrial processes and products - upholstered sofas - produced in the furniture cluster of Ubá-MG. The used material was collected from two sofas upholstered industries associated with the union of the furniture industries of Ubá region, located in Minas Gerais estate, Brazil. As for the product were evaluated dimensionally 29 upholstered sofas, with 12 being produced by industry "A" and 17 being produced by industry "B". As for the process, were evaluated: the socioeconomic profile of the worker and environmental factors of lighting and noise. The main results of this study showed that the upholstered sofas produced by industries, in general, fulfilled to the recommendations set out in the work in relation to the backrest height and useful seat depth. All the sofas, however, proved to be inadequate in relation to the seat height to the floor and the dimensions of the armrests Regarding environmental aspects, it was observed that in both industries, the activities in most jobs are performed under adverse conditions to the health and safety of workers and nonconformity with the limits set by Brazilian regulatory standard used in this work.     

Pisa—My Holy Beauty

This month,each writer details an impressive place,or scenic area, encountered while living abroad.身处异乡,喜欢去的一个地方……It was a sunny morning when I headed for Pisa.I knew I would definitely visit Torre pendente di Pisa(the Leaning Tower of Pisa).To me,it is the soul of the city,in which lies its glory and vigor.Compared with the surroundings,where low buildings stand     

The folly of theorizing “A” but testing “B”: A selective level-of-analysis review of the field and a detailed Leader–Member Exchange illustration

Leadership research has recently begun to emphasize the importance of examining the level of analysis (e.g., individual, dyad, group, organization) at which phenomena are hypothesized to occur. Unfortunately, however, it is still not commonplace for theory to clearly specify, and for investigations to directly test, expected and rival level-of-analysis effects. This article first selectively reviews a cross-section of theories, models, and approaches in leadership, showing generally poor alignment between theory and the level of analysis actually used in its testing. A multiple levels of analysis investigation of the Leader–Member Exchange (LMX) model is next presented. This theory has as its foundation the dyadic relationship between a supervisor and his or her subordinates. Yet, less than 10% of published LMX studies have examined level of analysis—and none has employed dyadic analysis. Using within- and between-entities analysis (WABA) and two different samples, four LMX level-of-analysis representations are tested, which involve monosource data; three of these models are then tested using heterosource data. Overall, good support is found for the LMX approach at the within-groups and between-dyads levels. Implications for aligning theory with appropriate levels of analysis in future research are considered.     

Parents' beliefs about children's emotions,children's emotion understanding,and classroom adjustment in middle childhood

To explore how parental socialization of emotion may influence children's emotion understanding, which then guides children's interpretations of emotion‐related situations across contexts, we examined the pathways between socialization of emotion and children's adjustment in the classroom, with children's emotion understanding as an intervening variable. Specifically, children's emotion understanding was examined as a mediator of associations between mothers' beliefs about the value and danger of children's emotions and children's adjustment in the classroom within an SEM framework. Classroom adjustment was estimated as a latent variable and included social, emotional, and behavioral indices. Covariates included maternal education, and child gender and ethnicity. Participants were a diverse group of 201 third‐graders (116 African American, 81 European American, 4 Biracial; 48.8% female), their mothers, and teachers. Results revealed that emotion‐related beliefs (value and danger) had no direct influence on classroom adjustment. However, children whose mothers endorsed the belief that emotions are dangerous demonstrated less emotion understanding and were less well‐adjusted in the classroom. Mothers' belief that emotions are valuable was not independently associated with emotion understanding. Findings point to the important role of emotion understanding in children's development across contexts (family, classroom) and developmental domains (social, emotional, behavioral) during the middle childhood years.     

The Role of Metacognition in Pathological Gambling: A Mediation Model

Pathological gambling involves multitudinous costs related to financial, legal, and public health care aspects, as well as to specific psychological disorders. Despite the overall evidence suggesting that comorbid disorders represent a risk factor for pathological gambling, there is scant evidence on the appropriate treatments for gamblers with such disorders. In this context, metacognitive therapy is an interesting approach because it considers psychological disorders as a result of the activation of perseverative cognitive processes and attentional strategies in response to inner events. Several studies report that metacognition is associated with different psychological problems. This study investigated the relationship among comorbid disorders, metacognition, and pathological gambling. 69 pathological gamblers at the first hospital admission and 58 controls drawn from general population (matched for age, gender, education) completed a battery of self report instruments: Symptom Checklist-90-R, Metacognition Questionnaire 30, South Oaks Gambling Scale. Compared to controls, pathological gamblers showed higher level of comorbid symptomatology and metacognition. Correlation analyses showed that: comorbid symptomatology and metacognition were positively and significantly correlated with pathological gambling; metacognition was positively and significantly associated with comorbid symptomatology. Mediation analysis indicated that dysfunctional metacognitive strategies could have an indirect effect on pathological gambling mediated by concurrent psychological disorders. These findings provide some implications for gambling treatment programs: pathological gamblers should be screened for psychiatric disorders, and metacognitive therapy could be considered a correct treatment of pathological gamblers. Metacognitive therapy might lead to the reduction of the pathological gambling by the diminishing of the concurrent psychological disorders.     

Is the beautiful always so good? Influence of physical attractiveness on the social perception of sexual harassment / ¿Es lo bello siempre tan bueno? Influencia del atractivo físico en la percepción social del acoso sexual

Research has shown that the perception of sexual harassment depends on factors such as gender, the situational context, the type of harassment, the ideology of the perceiver, the physical attractiveness of the harasser and victim and the relationship between them. This study focuses on examining the influence of physical attractiveness in the perception of a situation like sexual harassment. Through a questionnaire, 205 participants read a scenario in which a male worker (attractive vs. unattractive) engaged in gender harassment against a female colleague (attractive vs. unattractive). The participants then answered the measurements on the perception of harassment, responsibility, motivation and ideology. The main results were that the situation was more often perceived as sexual harassment when the victim of the harassment was physically attractive than when she was unattractive. Furthermore, the higher the participants’ acceptance of harassment myths the more they tended to blame the victim. We can conclude from this study the importance of the influence of certain myths or preconceived ideas about sexual harassment, which are found in both men and women, on how these situations are perceived.     

FINANCIAL MARKETS' SHUTDOWN AND REACCESS

We employ a discrete‐time parametric duration model on a group of 121 countries over the period 1970–2011 and find that the probability of the end of financial markets' shutdown and reaccess falls as these events become longer. We also show that: (1) shutdown episodes are longer when economic prospects are poor and the degree of financial openness falls, the chief executive has been in office for long periods, and the country has a default history and (2) spells of reaccess tend to be longer when economic growth improves and financial openness increases, there are neither government crises nor government instability, and the country did not default in the past.

Social closure,micro‐class immobility and the intergenerational reproduction of the upper class: a comparative study

This article assesses how processes of social closure enhance intergenerational immobility in the regulated professions and thus promote persistence at the top of the occupational hierarchy. We compare four European countries (GB, Germany, Denmark and Sweden) that differ considerably in their degree of professional regulation and in their broader institutional arrangements. We run log‐linear and logistic regression models on a cumulative dataset based on three large‐scale surveys with detailed and highly comparable information at the level of unit occupations. Our analyses indicate that children of licensed professionals are far more likely to inherit the occupation of their parents and that this stronger micro‐class immobility translates into higher chances of persistence in the upper class. These results support social closure theory and confirm the relevance of a micro‐class approach for the explanation of social fluidity and of its cross‐national variations. Moreover, we find that, when children of professionals do not reproduce the micro‐class of their parents, they still display disproportionate chances of persistence in professional employment. Hence, on the one hand, processes of social closure erect barriers between professions and fuel micro‐class immobility at the top. On the other hand, the cultural proximity of different professional groups drives intense intergenerational exchanges between them. Our analyses indicate that these micro‐ and meso‐class rigidities work as complementary routes to immobility at the top.
