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.     

Adolescent Adaptation to Parental Incarceration

This qualitative transcendental phenomenological study considered the lived experience of having a parent or parental figure incarcerated during one’s adolescence. The study analyzed 15 in-depth, in-person, semi-structured interviews with six participants between the ages of 18 and 29 from the city of Chicago. Textural-structural analysis indicated five separate results: the influence of parental incarceration on the developmental experience, the emotional influence of parental incarceration, the social influence of parental incarceration, the spiritual influence of parental incarceration, and the three key aspects of the experience (truth, the kind of relationship the participant had with the incarcerated parent, and the availability of an attuned subsequent caregiver). The analysis indicated that an adolescent’s adaptation to the world after experiencing this phenomenon fell into one of three spheres of adaptation. A number of clinical and social justice implications were identified along with avenues for future research to better understand the phenomenon and how it affects those who experience it.     

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.     

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).     

Ergonomic risk assessment with DesignCheck to evaluate assembly work in different phases of the vehicle development process

Occupational hazards exist, if the design of the work situation is not in accordance with ergonomic design principles. At assembly lines ergonomics is applied to the design of work equipment and tasks and to work organisation. The ignoring of ergonomic principles in planning and design of assembly work leads to unfavourable working posture, action force and material handling. Disorders of the musculoskeletal system are of a common occurrence throughout Europe. Musculoskeletal disorders are a challenge against the background of disabled workers. The changes in a worker's capability have to be regarded in the conception of redesigned and new assembly lines. In this way ergonomics becomes progressively more important in planning and design of vehicles: The objective of ergonomic design in different stages of the vehicles development process is to achieve an optimal adaptation of the assembly work to workers. Hence the ergonomic screening tool "Design Check" (DC) was developed to identify ergonomic deficits in workplace layouts. The screening-tool is based on the current ergonomic state of the art in the design of physical work and relevant EU legal requirements. It was tested within a federal German research project at selected work stations at the assembly lines at Dr.-Ing. h.c. F. Porsche AG / Stuttgart. Meanwhile the application of the screening-tool DC is transferred in other parts of the Porsche AG, Stuttgart. It is also realized as an ergonomic standard method to perform assembly work in different phases of the vehicle development process.     

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.     

Integrating regional and functional plans at Henkel

The article describes the planning system of the Henkel KGaA. The company is completely family owned. It is the fourth largest chemical company in Germany with affiliated companies nearly all over the world. The product range consists of consumer good articles such as detergents, cosmetics, household cleaners and adhesives and a wide range of chemical specialities which are sold to industry. The turnover world-wide is nearly DM7bn. The planning system of the Henkel KGaA is constructed in such a way that despite the necessity of short-term control the longer-term perspective still remains the basis for decision making. The planning structure and process throughout the company are explained in detail. The authors show that this system is an investment in managerial information processing.     

A process model of establishing knowledge management: Insights from a longitudinal field study

This paper contributes to the discussion on how to manage knowledge in organizations. Taking a perspective which acknowledges the importance of, but does not privilege, IT as the decisive element, it reports the results of a study investigating the process of establishing as opposed to conducting knowledge management. Based on a grounded theory approach to the analysis of the empirical data, a model of establishing knowledge management in organizations is developed. The model emphasizes how the organizational members make sense of the action and behavior of management, and how this understanding influences their own perceptions and actions in the process of establishing knowledge management. This leads to an understanding of knowledge management as an autonomous venturing process. The model is then used to suggest an explanation of why establishing knowledge management was not successful in the case which was investigated. Conclusions are provided on how the model can be further exploited for studying and improving the practice of knowledge management.
