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.     

The Tellado case study exercise: A metacritique

This paper provides an overview and critique of the papers in the Tellado Case Study Exercise. Two main themes are found in the critiques: the belief that Tellado lacked a clear audience for his evaluation and that he lacked an appropriate change orientation that would insure utilization. The sources of these criticisms are discussed from the perspective of evaluation as a linkage activity. The use of this perspective leads to the recognition that all parties to the case study may have focused on the wrong stakeholders in the utilization process. Thus, a major problem with utilization-focused and stakeholder based approaches to evaluation is revealed. Possible ways to avoid this problem are discussed. The paper concludes with a request for additional case studies to be contributed to the journal.     

The evaluator as program consultant

This paper presents a model for the role of the evaluator in which the evaluator acts as a Program Consultant who operates in three domains: Program Development, Planned Change, and Evaluation Technology. This permits the performance of evaluations that have greater validity and utility. The model is presented both from the theoretical perspective of linkage and from the context of the evaluation of a Case Management program operated by a Community Action Agency. Each of the domains is discussed with examples from the Case Management Evaluation. The paper concludes with a discussion of the contexts in which the model is best applied.     

Norwegian lottery winners: Cautious realists

The study investigated 261 lottery winners of prizes of NKR 1 million (US $150,000) or more in the years 1987–91 in a postal survey. The modal Norwegian winners were middle-aged married men of modest education, living in small communities. Emotional reactions to winning were few, aside from moderate happiness and relief. Winners emphasized caution, emotional control and unconspicuous spending, e.g. paying debts and sharing with children. There was only a slight increase in economic spending. A wish for anonymity was frequent, together with fear of envy from others. Betting was modest both before and after winning. Experiences with winning were predominantly positive. Life quality was stable or had improved. An age trend was observed, accounting for more variance than any other variable. The older winners seemed to represent a puritan subculture of caution, modesty and emotional restraint. A slightly more impatient pattern of spending was characteristic of younger winners. The results support Kaplan's 1987 and others' findings that lottery winners are not gamblers, but self-controlled realists and that tenacious, negative cultural expectations to the contrary are myths, but perhaps also deterrents of uncontrolled behavior.     

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.     

When should there be which kind of technology assessment? A plea for a strictly problem-oriented approach from the very outset

Technology assessment (TA) is generally classified as problem-oriented and thus transdisciplinary research. This is due to the fact that the aim of TA is to work out solutions for problems outside science in order to offer advice to its addressees, namely those working in politics and science and members of society in general. In this paper, we propose that the problem-oriented approach also be used as the basis for the decision regarding when a TA should be conducted in a particular situation, and which TA should be used. As a first step to this end, a broad range—almost like a kind of coarse radar—and large number of topics or problem sketches are created, which then serve as a basis for a discursive process of negotiation, during which topics are to be carried over into a detailed problem analysis (“fine radar”). These detailed problem analyses, which are important for transdisciplinary research, represent in themselves small research projects (pre-projects). They provide, in addition, some initial indications for a methodologically promising project design. The methodological approach described here is currently being tested in a procedure in which TA topics are being monitored for the German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF).
