ABSTRACT 1 : A wide ranging set of reforms is being introduced into the English National Health Service (NHS). They are designed to increase the market‐like behaviour of providers of care with a view to improving efficiency, quality and responsiveness of services. This paper is concerned with one aspect of those reforms: namely the policy to increase the diversity of types of providers of care to NHS patients. In this context, increasing diversity means that providers will not all be standard publicly owned NHS organizations. They can be publicly owned but autonomous, or independent (both in for‐profit and not for profit). The paper discusses the wide range of organizational forms available, analyzing their governance structures It then discusses the small amount of evidence currently available about the performance of diverse providers of health care. 相似文献

Although text messaging as a communication tool in society is rampant, research on its effects within print advertisements is lacking. To help fill this void, we employ three between-subject experiments (i.e., Study 1: text message vs. no text message; Studies 2 and 3: text message vs. traditional language). We posit that using text message copy in print ads is a unique (as grounded in distinctiveness theory) and fitting (as grounded in communication trust theory) approach to commune with targeted viewers and, therefore, should lead to favorable advertising outcomes. The experimental results confirm this notion. For example, responses concerning ad novelty, attention toward the ad, attitude toward the ad, purchase intention, and perceived brand trust are more favorable toward the text message condition ads. Implications and directions for future text message-related research are discussed. 相似文献

The ease with which 3D CAD models may be modified and reused are two key aspects that improve the design-intent variable and that can significantly shorten the development timelines of a product. A set of rules are gathered from various authors that take different 3D modelling strategies into account. These rules are then applied to CAD strategic-knowledge learning methodology and included in 3D CAD modelling exercises for students following the degree in mechanical engineering at the University of Burgos (Spain). The experiment was conducted in two groups with a total of 75 students. The design-intent rules were introduced in the different exercises that the teacher explained in both the theoretical and the practical classes. In addition, a summary of the different design rules in each of the practical exercises was explained in the practical classes in only one of the groups. The experimental results, reported in this paper, tested the influence of these summaries on overall improvements in 3D modelling and on the design-intent variable, which is subdivided into four sections: skeleton, structures, alterations and constraints. The use of the summaries of the design intent rules led to statistically significant improvements in 3D modelling in the experimental group, in comparison with the group of students to whom those summaries were not explained. 相似文献

Comovement,information production,and the business cycle 总被引:1,自引:0,他引:1
Recent theoretical research suggests that information production is a positive externality of aggregate economic activity (Veldkamp, 2005). Both the quantity and quality of information increase during periods of economic expansion and decrease during periods of contraction. Based on this insight, we hypothesize and confirm that time-varying information production drives the comovement patterns observed in stock returns. We examine stock return comovement in 36 countries from 1980 to 2007 and show that, consistent with the theory, comovement patterns are countercyclical; that is, when information production is high (low), comovement is low (high). We also find that the relation between comovement and the business cycle is stronger in countries that experience large intertemporal swings in information production. Finally, we show that the relation between business cycle and comovement is stronger in poor countries, countries with less developed financial markets, and countries with weaker accounting and transparency standards. These results suggest that financial development and transparency are conducive to a steady flow of financial information over the business cycle. 相似文献

Comparison of Cramer–Rao lower bounds of variances for at least equal protection of respondents 下载免费PDF全文

In this paper, a new randomized response model is proposed, which is shown to have a Cramer–Rao lower bound of variance that is lower than the Cramer–Rao lower bound of variance suggested by Singh and Sedory at equal protection or greater protection of respondents. A new measure of protection of respondents in the setup of the efficient use of two decks of cards, because of Odumade and Singh, is also suggested. The developed Cramer–Rao lower bounds of variances are compared under different situations through exact numerical illustrations. Survey data to estimate the proportion of students who have sometimes driven a vehicle after drinking alcohol and feeling over the legal limit are collected by using the proposed randomization device and then analyzed. The proposed randomized response technique is also compared with a black box technique within the same survey. A method to determine minimum sample size in randomized response sampling based on a small pilot survey is also given. 相似文献

We examine the effect of American International Group's (AIG) bailout, and the events leading up to it, on its insurance industry rivals. The reaction of rivals to AIG‐related events depends on the relative strength of two competing effects. The contagion effect implies that rival returns will decrease following negative events affecting AIG. In contrast, competitive effects will occur if investors expect that rivals will be able to benefit from AIG's downfall. Using three‐factor multivariate regression model event study methodology, we find evidence of both effects around several key dates in AIG's decline. 相似文献

One of the strategies employed by companies to differentiate themselves from others, in the food market, has been to market organic products according to the assumption that environmental values are an important influence on people's behavior. However, studies of the behavior of organic food consumers show that there is some debate on this subject. Although some studies associate organic food consumption with motives and attitudes in which the environment plays a predominant role, a greater number conclude that the motives for consuming this type of food are basically egoistic (related to health, food safety, or the quality or flavor of the food). This can lead to problems in deciding the central thrust of the marketing strategy. The purpose of this paper is to analyze the meaning and interpretations placed on the term “organic,” and how they are integrated, as a way to explain consumption behavior. Qualitative research methods were adopted for this purpose. Four focus group sessions with different sociodemographic profiles, held in the cities of Madrid and Seville, in Spain, displayed two evident paradoxes, which could indicate that environmental motives are not important for consumers in this market. It is concluded that the term “organic” plays an important role as a heuristic cue to superiority, irrespective of the consumer's knowledge about the real features of organic food. Three alternative models are presented to explain consumer behavior. These results could be useful to food companies, largely in connection with positioning this type of product and with their communications policy. 相似文献

AbstractIn an extension of generational theory, the present research argues that ethical ideology (i.e. idealism vs. relativism) impacts attitude toward the ad (Aad), attitude toward the brand (Abrand), and purchase intention (PI). Additionally, this research examines how this relationship is mediated by the ethical appraisal of the ad and moderated by the level of ethnic identification (i.e. high vs. low). The results of this experiment provide additional evidence in support of generational theory which states that each generational cohort holds distinct ethical ideologies. Furthermore, this study identifies differences in the participants’ responses to alcohol ads resulting from their personal values (i.e. in this study we focus on strength of ethnic identification). 相似文献

We consider returns from rebalanced and buy and hold portfolios consisting of the same stocks. Theoretical properties are derived using Jensen’s inequality and the Hölder’s Defect Formula. Simulations are used to confirm theory and to investigate ambiguous cases where theory is silent. Rebalancing decreases total return volatility, while buy and hold produces greater expected return. Results are more opaque with respect to Sharpe Ratios and expected geometric means. Our empirical tests are based on portfolios composed of the risk-free asset, CRSP market value returns and returns from five Fama–French industries. While rebalancing reduces volatility and momentum effect, our tests largely favor the buy and hold strategy due to the high relative returns enjoyed by stocks vis-a-vis the risk-free asset. Transactions cost for rebalancing the portfolio are economically negligible. 相似文献
