Study about upper limb on highly repetitive work in maquila operations

Industrial work is a very active sector in the economy of countries; an important part of people's work is done using the upper extremities. The purpose of this project is to characterize the effect of upper extremity work, analyze its relationship with the hand strength and the presence of fatigue and develop a model with the ability to estimate recovery times for the shoulder using variables different from the biomechanical variables.     

Analysis of mental workload of electrical power plant operators of control and operation centers

Electrical systems can be categorized as critical systems where failure can result in significant financial loss, injury or threats to human life. The operators of the electric power control centers perform an activity in a specialized environment and have to carry it out by mobilizing knowledge and reasoning to which they have adequate training under the terms of the existing rules. To reach this there is a common mental request of personnel involved in these centers due the need to maintain attention, memory and reasoning request. In this sense, this study aims to evaluate the Mental Workload of technical workers of the Control Centers of Electrical Energy. It was undertaken a research on operators control centers of the electricity sector in Northeast Brazil. It was used for systematic observations, followed by interview and application of the instrument National Aeronautics and Space Administration Task Load Index known as NASA-TLX. As a result there will be subsidies for an assessment of mental workload of operators, and a contribution to improving the processes of managing the operation of electric utilities and the quality of workers.     

What should I do?--a study about conflicting and ambiguous warning messages

Warnings are intended to reduce accidents caused by hazards. Behavioral compliance is the most important measure of warning effectiveness. However, in result of diverse circumstances (e.g., distraction, misuse, negligence), conflicting or ambiguous safety messages can be perceived. Since these are recurrent and can result in wrong behaviors encompassing severe consequences, such cases should be studied for safety purposes. We report findings on the participants' compliant behavior when performing a work-related task, while immersed in a virtual environment, and investigate the effect of conflicting messages on compliance with warnings. Two warnings (one regular and one with an appended out-of-order sign) and two types of signs (static and dynamic) were considered. The warning with the out-of-order sign configures the case of potentially conflicting messages. The gender effect was also investigated. The participants' behavior was assessed regarding to pushing a button as directed by the warnings. In the "out-of-order" warning, compliance was higher in the dynamic situation (53.3%) than in the static one (3.3%). Comparing with the non-conflicting warning, compliance was higher for both situations (static: 76.7%; dynamic: 100%). Women complied more than men. Although these results have limitations in their generalization, they are nonetheless relevant and deserve to be studied further.     

Measuring organizational effectiveness in information and communication technology companies using item response theory

The aim of this paper is to measure the effectiveness of the organizations Information and Communication Technology (ICT) from the point of view of the manager, using Item Response Theory (IRT). There is a need to verify the effectiveness of these organizations which are normally associated to complex, dynamic, and competitive environments. In academic literature, there is disagreement surrounding the concept of organizational effectiveness and its measurement. A construct was elaborated based on dimensions of effectiveness towards the construction of the items of the questionnaire which submitted to specialists for evaluation. It demonstrated itself to be viable in measuring organizational effectiveness of ICT companies under the point of view of a manager through using Two-Parameter Logistic Model (2PLM) of the IRT. This modeling permits us to evaluate the quality and property of each item placed within a single scale: items and respondents, which is not possible when using other similar tools.     

Implementation of an ergonomics program for the welding department inside a car assembly company

The premise for this project is to implement an ergonomics program for the welding department of a car assembly company, considering that this area represents the highest occupational risk in relation to musculoskeletal injuries. The project also allows the demonstration of the different implementation processes of an ergonomics program; it also permits the determination of individual risks faced by workers of the welding department, and finally gives a chance of improving common injuries using the sentinel system. The main challenge is to reduce musculoskeletal injuries and absenteeism among welders through actions implemented by the ergonomics program.     

The start up as a phase of architectural design process

Alterations made in the architectural design can be considered as a continuous process, from its conception to the moment a built environment is already in use. This article focuses on the "moving phase", which is the initial moment of the environment occupation and the start-up of services. It aims to show that the continuity of ergonomics interventions during the "moving phase" or start up may reveal the built environment inadequacies; clearly showing needs not met by the design and allowing making instant decisions to solve non-foreseen problems. The results have revealed some lessons experienced by users during a critical stage not usually included in the design process.

The circle of social reform: the relationship social work—social policy in Addams and Richmond

This article presents some results of a broader purpose of research on the thought and work of Addams and Richmond, particularly about the relationship between social work and social policy. First, we aim to contribute to deeper knowledge on the thought of these two pioneers on this relevant subject for social work nowadays and, particularly, to remove a relative veil of ignorance Richmond's involvement in social reform activities and elaboration on social reform in the context of the public and social policies process. Second, our proposal is to support a revision of the orthodox account on the antagonistic or irreconcilable nature of the two major traditions—social casework (or psychosocial approach) and social reform (or socio-political approach)—founded by two of the most influential figures of social work. Based on secondary and primary sources, the article focuses on the inseparable relationship between social policy and social work, clearly present in the thought and intervention of these seminal authors, and sheds new light on on-going debates and the disputed role of social policy perspectives within professionalised social work and the articulation between direct intervention with individuals, groups and communities and policy practice.     

Foreign Language Skills and Willingness to Move: The Case of a Spanish Region

This research is aimed at assessing the effect of foreign language skills on the geographical area selected by the Spanish unemployed when looking for a job. A Zero‐Inflated Ordered Probit (ZIOP) model has been estimated to analyse the impact of foreign language skills on the geographical scope of the search. The outcomes show that the job search area is broader in case of men, young unemployed, more educated people, and those who never received unemployment benefits. Likewise, foreign language skills (in English, German and French) are highlighted as one of the most influencing factors when widening the job search area.
