An easy method to construct efficient blocked mixture experiments in the presence of fixed and/or random blocks is presented. The method can be used when qualitative variables are involved in a mixture experiment as well. The resulting designs are -optimal in the class of minimum support designs. It is illustrated that the minimum support designs are more efficient than orthogonally blocked mixture experiments presented in the literature and only slightly less efficient than -optimal designs.  相似文献

Action Research is Similar to Design Science   总被引:2,自引:0,他引:2  
In management information systems (MIS) action research is long considered as promising but low-level research approach. It has an utmost relevance because action researchers are working with practitioners to solve the important practical problem. Design science outlined some years ago is just winning a wider audience. Action research was traditionally classified into qualitative research methods. But it seems to be the “wrong” home of action research. We shall show that after comparison of the seven aspects: concrete results of the study, knowledge produced, activities, the intent and the nature of a study, the division of labor in a study and generation, use and test of knowledge, the concordance between the characteristics of action research on the one hand and of design science on the other hand is very good. Hence, action research and design science should next be considered as similar research approaches, and this is a turning point in the history of both action research and design science.  相似文献

This article is based on the number of engineering officers from 1994 to 2000 in Taiwan, and adopts a 6-year moving average to work out the transition probability of engineering officers and to construct an absorbing Markov Transition Matrix to forecast the terms of seniority and annual supply in each hierarchy. In order to estimate the minimum number of vessels needed, this article also employed the quantity of demand for imported consumer goods from 1994 to 2000 in Taiwan and applied a Grey model to predict the annual quantity of demand for imported consumer goods. Furthermore, this article estimated the minimum number of demand for engineering officers according to the minimum number of vessels needed. In addition, this paper used cross-analysis to investigate the manpower supply and demand of engineering officers in Taiwan and obtained some important results, which can be valuable references for pertinent authorities.  相似文献

In this paper, the validity of vignette analyses of various forms of deviant behavior in the presence of opportunities is analyzed on the basis of ideas derived from cognitive psychology. Abelson’s Script Theory together with insights into human memory of visual and verbal information, allow the assumption that vignette analyses using visual stimuli are valid measures of deviant behavior in particular. The study includes an empirical examination of these ideas (n = 450). Nonparticipant observations and vignette analyses with visual and verbal material were carried out with regard to three forms of deviant behavior occurring in the presence of opportunities presenting themselves in everyday life. Observed and self-reported frequencies of deviant behavior or deviant intentions were counted and cross-tabulated. Log-linear analyses with dummy coding using observation data as reference category were run. Data analyses yielded the result that frequencies of deviant behavior were related to the techniques of data collection under consideration. Especially vignette analyses of the return of ‘lost letters’ that use both visual and verbal stimuli overestimate ‘actual’ (i.e. observed) return rates. This result is discussed with regard to the underlying methodological assumptions as well as its implications.  相似文献

A comparison is given of (ordinal) measures of trust in government institutions that were collected with the aim of facilitating comparisons between different modes and contexts of data collection. Statistical analyses reveal that the mode effect could amount upto a 10% change of item nonresponse and a 9% change of the level of trust, whereas the context effect could lead upto a 19% change of the bivariate associations of trust. The observed changes of both measures of central tendency and of associations affect conclusions of social scientific research in isolated studies, which implies that comparative studies are seriously hampered by bias related to mode and context, two sources of obscurity adding to the two other threats which are differences of sample source and differences of question phrasing.  相似文献

Putting value on cultural goods is a messy business. Cultural value is not just an economic act but instead part of an intense social process of valorization and legitimization. Art/culture is socially consumed and socially aware. Economic value is determined by intangible (and ephemeral) social value formed from and within specific contexts by particular people, the “scene”, so to speak. What are the mechanisms by which the social dynamics of art/culture impact its economic legitimacy? This article looks at how art/culture attains market value, focusing on the social contexts by which culture is produced, evaluated and distributed.  相似文献

Zusammenfassung  Die theoretisch-konzeptionelle Würdigung der Balanced Scorecard steht trotz ihres Siegeszuges in der Praxis noch immer in den Anf?ngen. Der vorliegende Beitrag weist die Systemtheorie, das Shareholder Value-Konzept und das Stakeholder-Konzept als theoretisch-konzeptionelle Bezugsrahmen der Balanced Scorecard aus. Damit werden zugleich Modifikationsm?glichkeiten der Balanced Scorecard angedeutet, die sich aus einer noch konsequenteren Anlehnung an einen der drei Ans?tze ergeben k?nnten. Prof. Dr. Jan K?rnert ist Inhaber des Stiftungslehrstuhls für Allgemeine Betriebswirtschaftslehre, insb. Internationales Finanzmanagement/Kapitalm?rkte Dr. Cornelia Wolf ist Gesch?ftsführerin des Studentenwerkes Greifswald  相似文献

The financial crisis started in 2007–8, initially in the US, but its consequences have been felt throughout the global economy. However, its effects were far from uniform. While parts of Asia and Africa continued to grow fast, Europe experienced a large set back. This paper emphasizes three important factors: differences across countries in technological development; differences in capacities to exploit the opportunities offered by technology; and differences in the ability to compete in international market. A formal model, based on this approach, is developed and applied to data for 100 countries in the period 1997–2012. Empirical indicators reflecting the various factors are developed, a dataset constructed and econometric estimates of the model performed. The results are used to explore the factors behind the slowdown in economic growth, with a particular emphasis on the continuing stagnation in Europe. A major factor turns out to be the increased financialization of the economy. The negative effect of the growth of finance prior to the crisis is especially pronounced for the countries that suffered most during the crisis.  相似文献
