Advertising research has generally not gone beyond offering support for a positive effect where ethnic models in advertising are viewed by consumers of the same ethnicity. This study offers an explanation behind this phenomenon that can be useful to marketers using self-reference theory. Our experiment reveals a strong self-referencing effect for ethnic minority individuals. Specifically, Asian subjects (the ethnic minority group) self-referenced ads with Asian models more than white subjects (the ethnic majority group). However, this result was not evident for white subjects. Implications for academics and advertisers are discussed. 相似文献

Radical changes have occurred in distribution in the UK over the past three decades. These structural changes have stimulated most retailers to increase their real advertising expenditure. The author analyses the main factors that have brought about the growing intensity of retail advertising as a form of non-price competition. 相似文献

This paper tests the relation between stock excess returns and risk factors measured by volatility. The sources of the volatility are based on the volatility of macroeconomic factors and time-series volatility. To model the macroeconomic fundamentals, we divide the risk into real and financial volatilities pertinent to Taiwan's economic environment. By examining the data of indusry excess returns and market excess returns, we find evidence to reject the hypothesis that the stock excess returns are independent of the real and financial volatilities. 相似文献

The incidence of THA (total hip arthroplasty) will rise with an aging population and improvements in surgery, a feasible alternative in health care can effectively increase medical quality. The reason of a hip joint replaced is to relieve severe arthritis pain that is limiting your activities. Hip joint replacement is usually done in people age 60 and older. Younger people who have a hip replaced may put extra stress on the artificial hip. This paper uses a serious data screening function by experts to reduce data dimension after data collection from the National Health Insurance database. The proposed model also adopts an imbalanced sampling method to solve class imbalance problem, and utilizes rough set theory to find out core attributes (selected 7 features). Based on the core attributes, the extracted rules can be comprehensive for the rules of medical quality. In verification, THA dataset is taken as case study; the performance of the proposed model is verified and compared with other data-mining methods under various criteria. Furthermore, the performance of the proposed model is identified as winning the listing methods, as well as using hybrid-sampling can increase the far true-positive rate (minority class). The results show that the proposed model is efficient; the performance is superior to the listing methods under the listing criteria. And the generated decision rules and core attributes could find more managerial implication. Moreover, the result can provide stakeholders with useful THA information to help make decision. 相似文献

Since the early 1980s, development experts and donor agencies have agreed on the importance of structural adjustment programs (SAPs) aimed at ‘getting prices right‘. Adoption of reforms were made preconditions for new loans or grants in many sub-Saharan African countries. In both Malawi and Cameroon, one such required reform was government's eliminating fertilizer subsidies to the small farm sector, previously used to increase the profitability of intensive agriculture while keeping food prices artificially low. The aim of this paper is to review fertilizer subsidy removal programs for their impact on farmers, who in sub-Saharan Africa are women. In theory, SAP programs should benefit women producers, because much emphasis is placed on renewing agricultural production and aligning farmgate prices with world prices. But in practice, will they benefit? Are SAPs gender-neutral and affect men and women equally, or merely gender-blind? 相似文献

This article proposes a new approach to evaluate volatility contagion in financial markets. A time-varying logarithmic conditional autoregressive range model with the lognormal distribution (TVLCARR) is proposed to capture the possible smooth transition in the range process. Additionally, a smooth transition copula function is employed to detect the volatility contagion between financial markets. The approach proposed is applied to the stock markets of the G7 countries to investigate the volatility contagion due to the subprime mortgage crisis. Empirical evidence shows that volatility is contagious from the US market to several markets examined. 相似文献

The aim of this study, with the pedagogic meal in focus, was to identify pre‐school staff members’ attitudes to the role of food and meals as part of daily activities at pre‐school. Interviews were carried out at 12 pre‐schools and a total of 34 pre‐school staff participated. The staff revealed strong opinions as well as ambivalence towards how food and meals should best be integrated into their daily work and pedagogic activities. The pre‐school staffs’ lack of or insufficient education and knowledge regarding food and nutrition resulted in an ambivalent and uncertain situation with respect to how they should see themselves as teachers in the meal situation. Nevertheless, most of the staff had a clear perception of what it meant to practice a pedagogic meal. It meant helping and encouraging the children to help themselves and serving as an adult model for the children at table, though this pedagogic activity was uncommon. While the staff were satisfied with the pre‐schools’ role of catering for the children, they expressed concern about or even mistrust towards the children's parents. Despite, or perhaps due to, their inadequate knowledge about food and nutrition and the lack of specific aims for the pedagogic meal, they assumed that the public sector was a better educational institution regarding foods and a better guarantor for children's food habits and dietary intake. As the teachers’ identities have changed over the past years they have not yet found a solid ground for determining how food and meals could be integrated into their everyday work as pre‐school teachers and childminders. 相似文献

This article analyses recent empirical data to explain why the youth labour market has disappeared over the last 20 years. The findings demonstrate that some young people stayed in education to acquire credentials, while others did so merely as a substitute for unemployment. Government policy is discussed in the light of these findings. 相似文献

The recent advent of the interest rate futures markets has greatly enriched the hedging opportunities of market participants faced with undesired interest rate risk. The variety of futures contracts presently spans a number of instruments with different risk, maturity, and coupon characteristics. This paper modifies the concept of duration and extends the duration hedging approach to cases where futures contracts are used as the hedging instrument. The derived hedge ratios take into account differences in coupon, maturity, and risk for three different regimes. Usage of these hedge ratios should lead to more efficient hedging of interest rate risk. 相似文献
