This research seeks to reconcile inconsistent results obtained in prior framing research in prosocial persuasion contexts by proposing that the reference point (self or self‐other) invoked in a persuasive appeal moderates the impact of a particular message frame (positive or negative) on attitudes and behavioral intentions. Two experiments were conducted in which frame and reference point were manipulated in persuasive messages promoting either recycling or prevention of HPV, a sexually transmitted disease. The results indicate that in persuasive social contexts, negative frames may be most persuasive with self‐referencing appeals while positive frames work best when benefits to self as well as others are emphasized. This suggests that developers of prosocial communications should be cognizant of both the message frame and the reference point invoked in these messages in order to have maximum persuasion impact. © 2007 Wiley Periodicals, Inc.  相似文献

The teaching of learning and thinking skills has become a primary objective of accounting education. Recent cognitive research has emphasized the importance of a framework for the organization of knowledge in attaining these skills. This paper examines whether a systems framework leads to improved long-term learning and higher level thinking skills. The systems framework involves the identification of objectives, users, inputs, and outputs, in addition to the calculation process. A learning experiment was conducted in which the systems framework was used for organizing material presented to students and for practice exercises. This study suggests that the systems framework enhances long term learning and higher level thinking skills. These results support the recent emphasis on information systems in accounting education.  相似文献

At the inception of the internal market in health care GP fundholding was seen rather as a 'sidesho' to the main reforms. But as the reforms have worked through, GP fundholding has emerged as pivotal to the purchaserlprovider agenda and the changes now associated with GP fundholding will be major issues in directing future health care policy initiatives. Drawing on empirical data from three Scottish regions, this paper argues that fundholding is now significant because GPs perceive benefits for primary health care. The paper uses the data collected from the case studies in the regions to assess these gains on two levels: the 'micro' impact of fundholding on primary health care processes and the 'macro' issues raised for health care policy by involving GPs more closely in resource management. Some GPs wish to use resource management as a vehicle for enhancing equity within the NHS, others are more concerned to manage resources so as to expand their practices into sites which combine primary, secondary and community health care, still others envisage developing the market to include monetary rewards for 'efficient' practices.  相似文献

Illiquidity, volatile returns and lack of information are sources of the high risk that characterise the investments made by venture capitalists (VCs). Despite the importance of such investments in the contemporary business and technological environment, and the associated risk-related difficulties, little Australian research has been conducted into the decision-making processes of VCs. This study investigates both the investment process and some of the strategies used by VCs for reducing selected risks. The specific source of risk examined is information asymmetry, which is caused by lack of information on the part of the VCs, and which can lead to the added risks of adverse selection and moral hazard. Four Australian VC firms were surveyed using a comprehensive open-ended questionnaire. A manual content analysis was employed to analyse the questionnaire responses. Consistent with prior research, the Australian VCs sampled are found to employ Berger and Udell' three steps of investment: selection, contracting and monitoring. Furthermore, the semi-formal selection step of the investment process is found to consist of three distinct stages: deal sourcing, screening and evaluation. A number of techniques are used to minimise the risks of information asymmetry during the screening and evaluation stages, as well as during the later steps of contracting and monitorin.  相似文献

It has always been assumed that consumer education serves the purpose of empowering people in their consumer role. This paper reviews the conventional understanding of consumer education and empowerment and then suggests an alternate approach. The argument is made for consumer education that helps people find their inner power and social potential to challenge the status quo, to change the system from a holistic perspective. Consumer empowerment of this type is totally self‐sustaining. Once learned, it cannot be unlearned. This form of sustainable consumer empowerment is the preferred direction for the future of consumer education.  相似文献

Among the different factors pertaining to the demand for durable inputs in agriculture, the way the input depreciates over time is an important issue. This study investigates four alternative capacity depreciation patterns for farm tractors. While published estimates from government agencies implicitly assume convex capacity depreciation patterns, the results of this study demonstrate that the use of agricultural engineering data which depict a concave rather than convex pattern better reflect farmers' investment decisions. An implicit rental price measure is also proposed to account for the fact that the purchase price of a durable input is not an appropriate measure of the implicit rental cost of the asset.
Parmi les facteurs déterminants de la demande pour les biens durables en agriculture, la rapidité avec laquelle I'intrant se déprécie est certainement importante lors des décisions d'investissement. La présente etude analyse quatre différents scénarios de dépréciation pour les tracteurs agricoles au Canada. Bien que les données publiées par les agences gouver-nementales supposent implicitement que les biens durables se déprécient à un taux annuel constant, les résultats de cette etude montrent que I'utilisation de données basées sur la valeur productive de I'intrant telle que calculée sur une base expkrimentale donne de meil-leurs résultats statistiques dans I'estimation de la demande pour les tracteurs agricoles. De plus, une mesure du coût implicite de I'intrant est également proposée pour tenir compte du fait que le prix d'achat n'est pas une mesure appropriée dans I'analyse de la demande pour un bien durable.  相似文献

L'objectif de cette étude est d'estimer les fonctions d'offre et de demande & quota de lait & transformation au Québec et en Ontario et d'évaluer les impacts potentiels d'un marché des quotas entre ces deux provinces. Les fonctions d'offre et de demande sont estimées par la méthode des moindres carrés à deux étapes et ce, pour quatre marchés, soit les marches des quotas produits et non produits dans chaque province.
Les résultats montrent que la flexibilityé de la demande est en général plus élévie en valeur absolue que celle de l'offre. Les résultats indiquent de plus que l'offre de quotas est élastique par rapport aux prix. Le modèle est utilisé pour simuler l'ouverture des marchés entre le Québec et l'Ontario. Les résultats indiquent que si un marché des quotas avait existé en 1992, le Québec aurait vu son quota de mise en marché augmenter de 3,4 % durant l'année, au détriment de l'Ontario qui aurait vu le sien diminuer d'environ 5,1%.  相似文献
