Economic incentives and the epidemiological indicators can contribute to the reduction of occupational hazards?

This article intends to discuss the interfaces of Decree No. 6042 and the adoption of its guidelines as a strategy to reduce the occupational hazards.     

Is occupational stress associated with work engagement ?

The occupational stress is associated with dissatisfaction, excessive demand at work and personal factors. Those factors can reduce work performance and can predispose workers to various diseases. Workers' health may be protected if there is encouragement to face challenges, which may lessen the impact on psychological and somatic stress and thus have greater personal and professional satisfaction. The aim of this study was to evaluate the association between occupational stress and work engagement. Participated in this study 457 male and female workers of a metallurgical industry. Subjects answered personal data, and the Job Stress Scale and Utrecht Work Engagement Scale were applied. Results showed an association between occupational stress and work engagement (P=0,001). The way the individual deals with his frustrations, or rather the work engagement, is associated with the occupational stress.     

Business games and implementation research

This paper reviews some recent research in OR implementation and suggests that a new approach is required, which will take fuller account of the perceptions of managers concerned with the problem. Research games in business settings seem to offer a means for such approach. Some lessons learned from a business game used in this way are described and their implications for modelbuilders are discussed.     

A DIRECT TEST OF THE BUFFER‐STOCK MODEL OF SAVING

Recent models with liquidity constraints and impatience emphasize that consumers use savings to buffer income fluctuations. When wealth is below anoptimal target, consumers try to increase their buffer stock of wealth by saving more. When it is above target, they increase consumption. This important implication of the buffer stock model of saving has not been subject to direct empirical testing. We derive from the model an appropriate theoretical restriction and test it using data on working‐age individuals drawn from the 2002 and 2004 Italian Surveys of Household Income and Wealth. One of the most appealing features of the survey is that it has data on the amount of wealth held for precautionary purposes, which we interpret as target wealth in a buffer stock model. The test results do not support buffer stock behavior, even among population groups that are more likely, a priori, to display such behavior. The saving behavior of young households is instead consistent with models in which impatience, relative to prudence, is not as high as in buffer stock models. (JEL: D91)     

DO TRANSFER TAXES REDUCE INTERGENERATIONAL TRANSFERS?

We estimate the effect of taxes on intergenerational transfers by exploiting a sequence of Italian reforms culminating with the abolishment of transfer taxes. We use the Surveys of Household Income and Wealth from 1993 to 2006, which have data on real estate transfers, and information on potential donors and recipients. Difference‐in‐differences estimates indicate that the abolition of transfer taxes increases the probability of high‐wealth donors making a transfer by two percentage points and increases the area transferred by 9.3 square meters relative to poorer donors.     

Assessment of quality of sleep and sleepiness in workers with rotating shifts

The study aims to evaluate the sleep quality and presence of daytime sleepiness in workers.     

A practical approach to the assesment of manual handling equipment for cargo: multinational abrasives in Brazil

The Manual Handling of Loads is an activity present in virtually all production system, when developed without ergonomic principles of design and sizing can generate several instances of discomfort and musculoskeletal disorders. This work was carried out to measure, set limits and risks and guide specifications for the cargo handling carts in a specific company, tracing the anthropometric profile of the productive population and performing a quantitative evaluation of forces and design models of cars used in the company.     

The World Bank model for global interdependence: A quantitative framework for the World Development Report

This paper describes the basic structure of the Global Model used in preparing various parts of the World Development Report (WDR) issued annually by the World Bank. The report is designed to help clarify linkages between the international economy and the domestic strategies of developing countries. The paper is divided in four parts. The first two present different aspects of the model structure and discuss the reasons that induced the authors to orient themselves towards given functional specifications. In the final parts the policy relevance of the exercise is studied in light of the results that the model has produced for 1975–1985.
