MultipLa--a tool for the combined overall estimation of various types of manual handling tasks

In the 1990ies the German Federal Institute for Occupational Safety and Health (FIOSH) published "Key Indicator Methods" (KIM) for the evaluation of manual material handling tasks. These methods served as a national German implementation of the EU Manual Handling Directive (90/269/EEC). These methods allow the evaluation of individual handling tasks like lifting or pushing. KIM tools do not allow evaluating complex handling tasks like a combined lifting and pushing task. With respect to the needs at shop floor level (e.g. logistics), MultipLa tries to bridge that gap by means of an EXCEL based worksheet using the KIM philosophy. In the past several algorithms for a risk assessment had been developed. At the moment MultipLa is in a test phase at several automotive OEMs.     

Charisma and organizational change: A multilevel study of perceived charisma,commitment to change,and team performance

What makes people perceive a leader as charismatic, and how do team leaders obtain performance outcomes from their followers? We examine leaders in times of organizational change and investigate the mechanisms through which leaders' change-promoting behaviors are associated with team performance. In a multilevel mediation model, we propose that the indirect relationship between change-promoting behaviors and team performance is sequentially transmitted through followers' perceptions of charisma and followers' commitment to change. A study of 33 leaders and 142 followers provides empirical support for the model, using multilevel structural equation modeling to analyze top-down relationships between leaders and followers and bottom-up relationships between followers and team outcomes. Results suggest that team leaders are perceived as more charismatic when they engage in change-promoting behaviors. These behaviors facilitate team performance through individual followers' perceived charisma and commitment to change.     

Issues for Men's Progression on English Social Work Honours and Postgraduate Degree Courses

This paper outlines the current knowledge base for men's experiences of studying social work in the UK. Given the relatively limited knowledge of these experiences, this paper also examines the findings from other literatures in order to inform this study, including nursing and primary school teaching educational literature. Men progress more poorly than women in social work, nursing and primary school teaching courses, and in other countries in addition to England. This paper also explores the educational experience of men in education and higher education more generally. The findings of a regression analysis are presented here. This analysis was conducted with secondary data from the GSCC of student progression on undergraduate and postgraduate social work courses in England between 2006 and 2011. Some potential reasons for these progression issues are identified from the related literatures and from the wider educational literature. Also indicated are some areas for further study to support a more diverse, representational profession and workforce.     

Stratified sampling using double samples

Usual stratified sampling design assume that one is able to draw units directly from given strata. If this is not possible, one can use the following double sampling procedure: First take a large simple random sample out of the whole population and find out, to which stratum each sample unit belongs. Out of these chosen units take a second stratified sample. In this paper unbiased estimators for this procedure in the cases of known (part I) and unknown (part II) stratum weights are proposed for sampling with replacement and sampling without replacement and their variances are evaluated.     

Freundschaftsnetzwerke in den neuen Bundesländern

Social networks were a very important component of the society of the GDR. This suggests a study of these networks — especially friendship networks — in Germany’s new federal states. Ego-centered friendship networks in the present, as well as for the final days of the GDR, are analysed with network-analytic methods. The 83 participants of the examination were selected via snowball sampling. The results are not homogenous. Some impressively document how people reacted to the circumstances in the GDR, while others do not show any difference to studies from the old German federal states. Some further results show that changes have taken place.     

Infants' Individuation of Rigid and Plastic Objects Based on Shape

Recent research suggests that 12‐month‐old infants use shape to individuate the number of objects present in a scene. This study addressed the question of whether infants would also rely on shape when shape is only a temporary attribute of an object. Specifically, we investigated whether infants realize that shape changes reliably indicate identity changes only in the case of rigid objects, but not in the case of deformable plastic objects. Twelve‐month‐old infants observed how either a rigid or a plastic object was placed in a box. When searching the box, they retrieved either an object with the same (no‐switch event) or with a different shape (switch event). Infants correctly inferred two distinct objects in the switch event in the case of rigid objects, but not in the case of plastic objects. A control experiment confirmed that this result was not due to a lack of salience of the shape transformation. Thus, infants' re‐searching behavior indicated that they viewed shape as being diagnostic in the individuation process of rigid objects only.     

Projective Identification and the Fear of Failing: Making Sense of Practice Educators' Experiences of Failing Social Work Students in Practice Learning Settings

The study focuses on emotional processes that may arise for practice educators when working with struggling or failing students in practice learning settings. Informed by a thematic review of the literature exploring the phenomenon of ‘failing to fail’, the study draws on two UK qualitative studies that highlighted the emotional distress experienced by practice educators when working with a marginal or failing student. The study draws key examples from these prior studies and argues that the psychoanalytic concept of projective identification offers a plausible and illuminating account of the states of mind experienced and reported by some practice educators in the ‘failing to fail’ dilemma. The notion is proffered as a conceptual framework for practice educators to explore and apply to their own practice as a means of making explicit unconscious states of mind, helping to recognise and rationalise these, thus supporting confidence in making appropriate assessment decisions.     

Correlations in between EAWS and OCRA Index concerning the repetitive loads of the upper limbs in automobile manufacturing industries

Upper limbs repetitive tasks are one of the main sources of risk for the workers of the manufacturing industries and the standards ISO 11228-3 and EN 1005-5 addressed this issue since 2007. EAWS (European Assembly Worksheet) is a 1st level ergonomic risk assessment method and it provides in its 4th section a score to measure the load level for the upper limbs based on a traffic light scheme. According to the relevant ISO/CEN standards, the OCRA Index is the preferred system to refer to in the evaluation of the biomechanical stress of hand-harm-shoulder system. This correlation study is based on a 45 workstations sample coming from the automobile manufacturing industry. According to the results, EAWS4 shows an excellent correlation with OCRA index (Spearman's rho correlation index 0.95). Being EAWS based on biometric statistical data distribution, its typical application is the process design phase, but adopting a conservative approach in the interpretation of EAWS4 score for risk mapping purposes, it provides an equivalent "reaction" pattern (countermeasures to be taken in the production phase) with respect of OCRA Index with an Odds Ratio ranging from 0.89 (OR-matched) to 1.00 (OR-conservative).     

Prevention of MSD by means of ergonomic risk assessment (tools) in all phases of the vehicle development process

In industrialized countries musculoskeletal disorders (MSD) play an import role and are often responsible for almost one third of the total sick leave. The changes in the demographic profiles, i.e. aging work forces might even worsen this situation in the future. For a highly productive and sustainable use of human resources in production systems, ergonomics offers high potentials. In the recent years the authors have developed several ergonomic risk assessment tools, especially for the use in automotive industries. These methods may be used during the planning phases in the Tech Centers as well as during the production phase at shop floor level. The tools might also be used for a standardized communication in between the Tech Center and the plants to improve the effects of "lessons learned" for the design and layout of workstations and processes and the optimization of vehicle components. This paper describes suitable risk assessment tools as well as the integration of these tools into the vehicle development process. It introduces a comprehensive management approach for the integration of ergonomics into the management of production systems.
