Beratungsforschung mit,für oder ohne die Praxis?

This article deals with the extent to which consulting research and consulting practice are pulling in the same direction or whether the gap between them still seems insurmountable. Therefore we examine the literature on consulting research, report what kind of research coaching practitioners would consider beneficial and introduce first findings from an empirical survey in which coaching practitioners were asked about their motivation for—or against—taking part in coaching research.     

How union mergers affect membership participation

Using data from a survey of union members, we explore how an amalgamation of two Swedish unions affects membership participation. The research literature on the topic is mostly anecdotal and speculative, suggesting that mergers might have detrimental effects on membership participation because they create large unions with centralized governance and administration. But in this study, we do not find a broad-based decline in membership participation measured before and after merger as well as in relation to a comparison union that did not merge. These results are discussed in terms of the national context of union mergers in Sweden and the ways that mergers are negotiated, presented, and implemented to preserve membership participation. An earlier version of this paper was presented at the Third International Conference on Emerging Union Structures: Reshaping Labour Market Institutions, Canberra, Australia in December 1997. The data collection for this project was supported by funds from the National Institute for Working Life in Stockholm.     

Ridge estimation of restricted parameters in production techniques

The problem of determining ridge estimates of the regression parameters in a two-input production function model,constrained to be non-negative,has been formulated as an exercise in quadratic programming. Relevant Kuhn-Tucker conditions have been derived and a small simulation studv has been carried out.     

Authority and the pursuit of order in organizational performance

The paper seeks to examine the site of performance, the spatial context of the dramatic act, and to consider the various ways in which performance is regulated, ordered and sustained. In particular, the paper is concerned with the relationship between authority and propriety in the regulation of the performance site and with the transformational metaphors which sustain the trajectory of the performance. The basic premise on which the argument rests is that there is a equivalence of sign-imagery as appropriate to liturgical performance which is the basis of some forms of organisational behaviour and that this equivalence permits more than the mere playing out of ritualistic behaviour: it appropriates the image in the reproduction and re-presentation of its forms. Consequently, the significance of the elevation, for instance, of The Cross or the consecrated Host, the notion of ritualistic cleansing, of humiliation, of redemptive acts, of public confession, become emblematic means of achieving organisational incorporations and of achieving movement from the isolated “I” to the collective “We”.     

Nanotechnology Risk Communication Past and Prologue

Nanotechnologies operate at atomic, molecular, and macromolecular scales, at scales where matter behaves differently than at larger scales and quantum effects can dominate. Nanotechnologies have captured the imagination of science fiction writers as science, engineering, and industry have leapt to the challenge of harnessing them. Applications are proliferating. In contrast, despite recent progress the regulatory landscape is not yet coherent, and public awareness of nanotechnology remains low. This has led risk researchers and critics of current nanotechnology risk communication efforts to call for proactive strategies that do more than address facts, that include and go beyond the public participation stipulated by some government acts. A redoubling of nanotechnology risk communication efforts could enable consumer choice and informed public discourse about regulation and public investments in science and safety.     

R–estimation of normed bivariate density functions

Normed bivariate density funtions were introduced by HOEFFDING (1940/41). In the present paper estimators for normed bivariate ranks and on a FOURIER series expansion in LEGENDRE polynomials. The estimation of normed bivarate density functions under positive dependence is also described     

The Relationship Between Aversive Conditioning and Risk-avoidance in Gambling

This study investigated the relationship between aversive conditioning, heart rate variability suppression, behavioral activation system/behavioral inhibition system and risk-avoidance on the Iowa gambling task (IGT) in a nonclinical sample (29 male, 29 female, mean age = 20.7). A laboratory based Pavlovian aversive conditioning paradigm was used where a 1500 Hz tone (CS+) was followed by a burst of loud white noise (US), and a 850 Hz (CS−) tone was never followed by the US. In a subsequent extinction phase where the CS+ and CS− were presented without the US, conditioned skin conductance responses to the CS+ indicated aversive conditioning. The results showed that the participants who did not show aversive conditioning (N = 26) exhibited significantly less risk-avoidance compared to participants who did show aversive conditioning (N = 32). Regression analysis showed that among the study variables, only aversive conditioning contributed significantly to explaining variance in risk-avoidance. These results may have implications for understanding risk-taking in gambling in general, and may be a starting point understanding the role of aversive conditioning in the development and maintenance of gambling problems.     

Changes in the structure of health complaints as related to shiftwork exposure

Abstract

Factor analyses of health complaints in groups with different length of shiftwork exposure show that the structure of these complaints changes with increasing shift experience, indicating the emergence of a shift-specific pattern of health complaints. After about 15 years of shiftwork, complaints related to disturbances of circadian-controlled functions can be found in the first factor whereas other complaints have their dominant loadings on a separate factor, representing general, non-shift-specific impairments. The results indicate that in this way shift-specific components of health impairment can be separated from other non-shift related components.     

Efficient estimation in the Pareto distribution

The maximum likelihood estimation (MLE) of the probability density function (pdf) and cumulative distribution function (CDF) are derived for the Pareto distribution. It has been shown that MLEs are more efficient than uniform minimum variance unbiased estimators of pdf and CDF.
