Patients decide on where to consume hospital services in Germany. Thus, the understanding of the exact hospital selection criteria and their weights is important. This research reviews the antecedents of hospital selection utilizing the conjoint methodology with regard to six questions. (1) Which are the relevant choice criteria, and (2) what are their weights? (3) Which criteria receive an increased importance in the absence of experience? (4) Do differences between compulsory and privately insured patients, (5) between hospitals with regard to their size, and (6) between female and male patients exist? The relevance and importance of nine pre-selected criteria are determined through two conjoint analyses. Experience is found to be most important followed by referral by general practitioner, certified quality management system, positive press coverage, recommendation by relatives and acquaintances and distance to the hospital. Reception area design and the personnel's friendliness, the website quality and the published quality report are less relevant. Without experience, reception area design, personnel's friendliness and distance to the hospital receive an increased importance. In addition, for some criteria notable discrepancies between female and male patients and between patients with different insurance policies are found.  相似文献

Consumers worldwide are increasingly concerned with sustainable production and consumption. Recently, a comprehensive study ranked 17 countries in regard to their environmentally friendly behaviour among consumers. Brazil was one of the top countries in the list. Yet, several studies highlight significant differences between consumers' intentions to consume ethically, and their actual purchase behaviour: the so‐called ‘Attitude‐Behaviour Gap’. In developing countries, few studies have been conducted on this issue. The objective of this study is therefore to investigate the gap between citizens' sustainability‐related attitudes and food purchasing behaviour using empirical data from Brazil. To this end, Brazilian citizens' attitudes towards pig production systems were mapped through conjoint analysis and their coexistence with relevant pork product‐related purchasing behaviour of consumers was investigated through cluster analysis. The conjoint experiment was carried out with empirical data collected from 475 respondents surveyed in the South and Center‐West regions of Brazil. The results of the conjoint analysis were used for a subsequent cluster analysis in order to identify clusters of Brazilian citizens with diversified attitudes towards pig production systems, using socio‐demographics, attitudes towards sustainability‐related themes that are expected to influence the way they evaluate pig production systems, and consumption frequency of various pork products as clusters' background information. Three clusters were identified as ‘indifferent’, ‘environmental conscious’ and ‘sustainability‐oriented’ citizens. Although attitudes towards environment and nature had indeed an influence on citizens' specific attitudes towards pig farming at the cluster level, the relationship between ‘citizenship’ and consumption behaviour was found to be weak. This finding is similar to previous research conducted with European consumers: what people (in their role of citizens) think about pig production systems does not appear to significantly influence their pork consumption choices. Improvements in the integrated management of this chain would better meet consumers' sustainability‐related expectations towards pig production systems.  相似文献

Peter Boettke (2007) argues that economists need not act pluralistically in order for pluralism to thrive in the marketplace of economic ideas. From a market process perspective, Boettke sees intellectual diversity and openness as catallactic outputs, not inputs—emergent by-products of academic specialization and trade. To expect individual scholars to behave in a pluralistic manner is unnecessary and “completely inappropriate” since it detracts from their central task: “to commit themselves to an approach and pursue it doggedly, even in the face of great doubt and resistance by one’s peers” (Boettke 2007). This paper proposes a Smithian revision of Boettke’s position. The author argues that scholarly pluralism is best understood as a constitutional rule of academic life—a virtue ethic that promotes learning and intellectual freedom by mitigating tyranny and autarky in the republic of science. Drawing from the writings of Adam Smith, Friedrich Hayek, Deirdre McCloskey, Bruce Caldwell, James Buchanan, Don Lavoie, and Boettke himself, the author argues that scholarly pluralism has been, and continues to be, a necessary condition for the flourishing of Austrian economists as free, responsible, efficacious thinkers.  相似文献

This article explores project management offices (PMOs) through community of practice theory. Preliminary results from a national health care case study are used to confirm the legitimacy of this approach. Today's knowledge‐based economy calls for mechanisms to share knowledge. The issue of making more with less is at stake in order to reuse good practices, support innovative practice, and prevent the reinvention of the wheel. Members of these communities are at the heart of the learning process. The originality of this research is that it sheds light on PMOs in a new theoretical perspective within the field of knowledge management.  相似文献

We examine determinants of different types of International New Ventures (INVs), namely Export Start‐up, Geographically Focused Start‐up, Multinational Trader, and Global Start‐up. Whereas this typology of INVs has been widely accepted in the literature, empirical testing of the determinants of INV types is largely missing. Our arguments build on the International New Venture Theory (INVT). Hypotheses generated from our framework are tested on 195 German high‐tech enterprises. Results show that growth orientation, prior international experience, knowledge intensity, product differentiation, and learning orientation distinguish significantly between the different INV types.  相似文献

Nach der Atomkatastrophe in Fukushima hat die Bundesregierung beschlossen, bis Mitte Juni die Zukunft der Atomenergie in Deutschland zu überdenken. Dabei k?nnen unterschiedlich weitgehende Szenarien betrachtet werden. Sie reichen von einer Rücknahme der im letzten Herbst beschlossenen Laufzeitverl?ngerung bis hin zum vollkommenen Ausstieg aus der Kernkraft. Die Autoren vertreten grunds?tzlich die Auffassung, dass die wirtschaftlichen Folgen eines Atomausstiegs zu bew?ltigen sind. Mit einer Steigerung der Energiepreise muss allerdings gerechnet werden — wie deutlich diese ausf?llt, und welche Referenzwerte herangezogen werden müssen, h?ngt von vielen Faktoren ab.  相似文献

In light of the shortcomings of the Stability and Growth Pact, there has been a recognition that a surveillance framework is needed which goes beyond fiscal issues to cover wider macroeconomic factors. The question arises whether the surveillance and connected reform criteria should be applied symmetrically, to all members of the eurozone, or whether they should specifically target countries with current account deficits.  相似文献
