IEA/WHO toolkit for WMSDs prevention: criteria and practical tools for a step by step approach

When studying WMSDs, several determinants and their interrelationship are considered as relevant. Hence the necessity of an "holistic" approach to prevention, especially when preparing technical rules and strategic plans. There is a strong request, from OSH agencies and operators, for developing "simple" tools for risk assessment and management. In this context WHO asked IEA to develop a "Toolkit for WMSD prevention". The paper presents one of the main contribution to this WHO project, focused on selecting tools at different level for hazard identification, risk estimation and management. Proposals are based on two essential criteria: Acting on a step-by-step approach; Taking into account the presence of multiple influencing factors. The proposals consider: A Basic Step devoted to hazard identification by operative "key-enter" questions, that can be operated also by non-experts. A First Step, (quick assessment), for identifying 3 possible conditions: acceptable; high risk present; more detailed analysis (via tools presented at second step) necessary. This step can be operated by non-experts with only some specific training. A Second Step, where recognized (i.e. from international standards or guidelines) tools for risk estimation are used. This step can be operated only by persons with some specific training.     

Ergonomics in designing process: dialogue between designers, executors and users in the maintenance activity of radars in an oil refinery

This paper aims to discuss the role of ergonomics in design process using the dialogue developed by designers, implementers and users in an oil refinery. It was possible to identify the need of minimizing the postural constraints, risk of accidents, mechanical shocks and to enlarge safety perception in the access and permanency of the users at the workspace. It has been determined and validated by workers and managers to implement different deadlines depending on programming, viability and execution time for the improvements proposed. In a long-term: it was proposed the substitution of the ladders with time planning according to the maintenance program of the tanks; in a short-time: it was suggested the expansion of the existing platforms, implementation of a walkway connection provided with guardrails between the upper access of the side ladder and the repositioning of radar set and aerial aiming at the usage by workers at the workstation of the new platform. It was also elaborated eight typologies of intervention, according to the request, type of tank, material stored, and its setting place. The design process arises from ergonomics workplace analysis that presents concepts for solutions which was a mediator tool to be settled between users and implementers.     

Facts and Theories of the Italian Labour Market (1970-1985): A Time Series Analysis of Wages,Employment and Prices

ABSTRACT: ln this paper an attempt is made to determine whether observed patterns of intertemporal variability in a number of Italian labour market characteristics are consistent with the predictions forthcoming from three prominent models of aggregate labour market behaviour. The behavioral models included in the analysis are: a) intertemporal substitution labour supply, b) staggered wage contracts, and c) intertemporal labour demand with adjustment costs. The empirical results provide relatively more support for the validity of the adjustment cost model.     

Employment Trajectories Beyond Retirement

Within the political and academic debate on working longer, post-retirement employment is discussed as an alternative to maintain older workers in the labor market. Our article enhances this discussion by studying determinants of transitions into post-retirement jobs within differing work environments of birth cohorts 1940–1942. We estimate proportional subhazard models accounting for competing risks using unique German social security data linked to pension accounts. Our findings suggest that individuals’ preferences to take up post-retirement jobs are not mutually exclusive. Our study provides evidence that taking up post-retirement jobs is related to seeking financial security, continuity, and work ability, suggesting that public policy has to develop target-oriented support through a public policy mix of different measures aligned to the different peer groups in the labor market.     

Making sources of energy: the case of coal (1900–1936)

Recent contributions to a sociological analysis of energy and society focus mostly on its political, economic and technological organization. Yet contrary to other parts of nature, little social scientific attention has been paid to how politics, economics and technology have come to produce and stabilize the concept of energy in the first place and how different natural materials were transformed into “sources of energy.” Drawing from insights of the sociology of comparison, quantification and commensuration, “energy” in this paper is conceived as a “statistical object,” around which a public discourse develops in which comparisons between resources are drawn. Since the beginning of the twentieth century, this discourse has been more and more stabilized by the regular, public production and ever tighter net of elements of comparison, the creation of a highly abstract, potentially quantified point of comparison, and the definition of various criteria tying the compared entities together with more general models and narratives. This theoretical framework is put into practice by an explorative analysis of coal classification in the first quarter of the twentieth century. In this empirical analysis, three fields are identified where coals were “made the same”: engineering, economics and resource statistics. It is shown that the “calorific value” plays an important role for classification in all three fields and, furthermore, constitutes a measure that links coal to other fuels.     

How Leaders Affect Followers’ Work Engagement and Performance: Integrating Leader−Member Exchange and Crossover Theory

Drawing on leader?member exchange and crossover theory, this study examines how leaders’ work engagement can spread to followers, highlighting the role of leader?member exchange as an underlying explanatory process. Specifically, we investigate if leaders who are highly engaged in their work have better relationships with their followers, which in turn can explain elevated employee engagement. For this purpose, we surveyed 511 employees nested in 88 teams and their team leaders in a large service organization. Employees and supervisors provided data in this multi‐source design. Furthermore, we asked the employees to report their annual performance assessment. We tested our model using multilevel path analyses in Mplus. As hypothesized, leaders’ work engagement enhanced leader?member exchange quality, which in turn boosted employee engagement (mediation model). Moreover, employee engagement was positively linked to performance and negatively linked to turnover intentions. As such, our multilevel field study connects the dots between work engagement research and the leadership literature. We identify leaders’ work engagement as a key to positive leader?follower relationships and a means for promoting employee engagement and performance. Promoting work engagement at the managerial level may be a fruitful starting point for fostering an organizational culture of engagement.     

Health and Well–Being in the Young Old and Oldest Old

Most individuals experience a decline in health status during old age. Paradoxically, there are proposals that older adults nevertheless maintain a positive sense of well–being, an indicator of successful aging. Data from the Berlin Aging Study (BASE: Baltes & Mayer, 1999), a locally representative sample of men and women aged 70 to 100+ ( N = 516, M = 85 years), suggest that cumulative health–related chronic life strains set a constraint on the potential of oldest old individuals to experience the positive side of life. The young old in BASE reported significantly higher positive SWB than did the oldest old. Chronic illness and functional impairments (e.g., vision, hearing, mobility, strength) limit well–being especially in very old age.     

Child-Care Choices by Working Mothers: The Case of Italy

In spite of relatively generous public subsidies and a reputation for high quality, only a very limited proportion of Italian families use public child-care and a large proportion use informal care. In this paper, we attempt to explore the determinants of the use of child-care among dual workers families. Given the limitations of data available we match two different data sets: the Bank of Italy (SHIW) and ISTAT Multiscopo. We find evidence that the availability of public child-care affects in an important way its demand. We also find that increases in costs of public child-care reduce the use of public as well as private indicating a shift to informal child-care. The presence of a grandmother who lives near and is in good health is an important explanation of the choice especially in presence of very small children. An understanding of the importance of these factors is relevant in the evaluation of child-care policies. This is particularly important in Italy, where the majority of families with children have only one child and children would benefit also from the socialization aspects of the child-care system. We would like to thank Christopher Flinn, Massimiliano Bratti, and Maria Concetta Chiuri for helpful comments, Donald Rubin for useful hints on the matching procedure, and participants at the ESPE meeting in New York 2003, the EALE meeting in Lisbon 2004.
