Zusammenfassung Den Ausgangspunkt der überlegungen bildet die Interpretation von Dienstleistungen als Probleml?sungen, die eine M?glichkeit
zur formalen Analyse der Output-Flexibilit?t er?ffnet. Im vorliegenden Beitrag werden in einer eigenschaftsorientierten Betrachtung
zun?chst die Komponenten der Output-Flexibilit?t identifiziert, um dann darauf aufbauend ein Kalkül zur Gestaltung der Output-Flexibilit?t
von Dienstleistungsunternehmungen abzuleiten.
Summary Output flexibility enables the service provider to cope with both uncertainties in demand and the external production factor. This paper aims at formulating a calculus for the design of output flexibility based on production theory. The interpretation of services as specific problem solutions serves as a basis for a feature-oriented modelling of service production.

Mainstream brand management literature views brands as products or organisations carrying brand names and brand managers as being in control of brand-related actions and outcomes. By contrast, recent empirical research shows the substantial influence of stakeholders on brands. Together with brand management, stakeholders shape brands by participating in brand-related interaction. European brand research accordingly treats brands as ongoing and complex processes in constant flux. Nevertheless, literature suffers from a significant lack of theoretical underpinnings for understanding brands as complex processes; in this respect, building on European philosophy is a fruitful avenue. This paper introduces the metaphor of the rhizome and draws on European process philosophy to further develop an integrative processual understanding of brands. Brand management claiming control over brands as processes turns out to be a delusion. 相似文献

Waste management has become a major environmental issue in Germany. The siting of waste incineration especially arouses strong local opposition. The study presented here is related to such a case (i.e., a planned waste incineration facility in a small West German village). The study is based on a telephone survey aimed at the information needs of the residents. Two topics are stressed: (1) the thematic relevance of the siting project as seen by the public; and (2) the residents'information needs. The results show that a majority of residents are concerned about the planned facility, and the most important topics of their information needs refer to the risks and the safety systems of the planned facility, as well as information about waste management alternatives. Furthermore, the information needs depend on the personal relevance of the issue and the perceived knowledge deficit about it. Conclusions are drawn with regard to the design of a risk communication program. Here, four groups of residents are distinguished in terms of knowledge and motivation and, thus, need to be approached in different ways. 相似文献

Previous research has found that alternative employment arrangements are associated with both impaired and improved well-being. Since such inconsistencies are likely to derive from the type of employment contract as well as the characteristics of the job, this paper compares permanent full-time work with forms of alternative employment (permanent part-time, fixed-term and on-call work) in order to investigate how different employment contracts and perceptions of job conditions relate to individual well-being. This study contributes to the literature by addressing several questions. Different forms of alternative employment are distinguished and individual background characteristics that might be intertwined with the employment contract are controlled for. Moreover, the scope of this study extends to the effects of perceived job conditions, and possible interactive effects with type of employment are tested. Analyses of questionnaire data from 954 Swedish healthcare workers show that perceptions of the job (job insecurity, job control and demands), but not the type of employment contract, predicted health complaints. However, type of employment interacted with perceptions of job insecurity, in that insecurity was associated with impaired well-being among permanent full-time workers, while no relationship was found for on-call or core part-time employees. Despite the absence of interactions between employment contract and job demands or job control, it can be concluded that knowledge about the relationship between alternative employment arrangements and the well-being of workers can be enhanced when the combined effects of employment contract and job conditions are studied. 相似文献

Covariance matrices, or in general matrices of sums of squares and cross-products, are used as input in many multivariate analyses techniques. The eigenvalues of these matrices play an important role in the statistical analysis of data including estimation and hypotheses testing. It has been recognized that one or few observations can exert an undue influence on the eigenvalues of a covariance matrix. The relationship between the eigenvalues of the covariance matrix computed from all data and the eigenvalues of the perturbed covariance matrix (a covariance matrix computed after a small subset of the observations has been deleted) cannot in general be written in closed-form. Two methods for approximating the eigenvalues of a perturbed covariance matrix have been suggested by Hadi (1988) and Wang and Nyquist (1991) for the case of a perturbation by a single observation. In this paper we improve on these two methods and give some additional theoretical results that may give further insight into the problem. We also compare the two improved approximations in terms of their accuracies. 相似文献

This paper proposes and applies a test procedure for misspecification in a dynamic regression model with moving average errors. The test statistics are based on testing for unit roots in the moving average process when the model is deliberately overdifferenced. 相似文献

The study investigates phonological variation and change in two varieties of standard Dutch: southern standard Dutch (spoken in Flanders, the northern part of Belgium) and northern standard Dutch (spoken in the Netherlands). A new source for studying language change in progress is introduced: archived recordings of radio broadcasts. The study covers the period from 1935 to 1993. Changes in progress are studied by a combination of insight and techniques from historical linguistics and sociolinguistics. The outcomes of analyzing separate linguistic variables are presented, but the focus of the analysis is on the presence of more general patterns of covariation within the set of linguistic variables and on the possibility of distinguishing (prototypical) temporal and community-based varieties of standard Dutch. The results reveal a pattern of divergence between the two varieties of standard Dutch. The southern variety remained more or less stable between 1935 and 1993. Northern standard Dutch, however, changed substantially. 相似文献

This study presents the results of a survey of graduate students from three cultural backgrounds. English, German, and American business students responded to an eleven-item survey designed to assess one's beliefs about what is necessary to succeed in graduate business programs. The results indicate that the attributes which students believe are required to succeed differ among cultures, with the greatest differences occurring between the American and European respondents. 相似文献
