Advertisements often display ideal female bodies which create unattainable standards of beauty, generating body anxiety and disorders in female viewers. Accordingly, public health concerns would encourage the use of natural, unedited models in advertisements. However, the advertising performance of natural models remains contentious. We argue that previous inconsistent findings about this performance may result from a complex causal framework in which natural models impact performance through two affective mediators (body anxiety, and repulsion toward the model), while allowing moderation by the viewer's own body mass index (BMI). Data collected in a nationally representative sample of 400 young women largely (but not entirely) validate this causal framework. Natural models triggered repulsion in viewers with higher BMI, which hurt advertising performance. Body anxiety, however, was positively correlated with advertising performance, and did not mediate any effect of natural models. 相似文献

The emerging market of the UAE has chosen attracting international tourism as one of the main strategies during the recent decades in order to diversify its economy. The main goal has been to achieve sustainable growth without overreliance on the volatile oil sector. This article investigates the impact of tourism on economic performance in the UAE by using bootstrapped causality tests with leverage adjustments. The results show that the tourism-led growth hypothesis can be supported empirically. Thus, the conducted policy by the UAE government to promote international tourism for achieving economic growth might be considered as a sustainable strategy. 相似文献

This paper aims to test whether the regional house prices are convergent or divergent in China using a monthly panel data set of China’s 70 large and medium-sized cities from July 2005 to December 2010. This issue is closely related to understanding the efficiency of the country-level housing policies made by China’s central government. The test results suggest that the regional house prices in China are generally divergent, and thereby the country-level policies may be inefficient since they do not explicitly take the strong heterogeneity of China’s regional housing markets into consideration. As a consequence, it may be better for China’s central government to further decentralize and devolve its governance toward the housing market to the local governments. 相似文献

The diversity between the country-scores of Hofstede, Schwartz, GLOBE, Håkanson and Ambos and Dow and Karunaratna is the main focus of this study. To investigate the correlation between the country-scores of these CD (Cultural Distance), pPD (perceived Psychic Distance) and PDs (Psychic Distance stimuli) instruments we apply the Mantel test, a test predominantly used in anthropology and genetics, which can be particularly insightful when examining “distance” data. The matrix correlation findings provide evidence supporting the high diversity between these measures and their lack of consistent results for the same countries. Therefore, despite the similarity between the way of conceptualizing and operationalizing CD that Hofstede, Schwartz and GLOBE share, these CD measures do not report consistent findings. Consistently, the lack of correlation, between the PDs measure of Dow & Karunaratna and pPD of Håkanson & Ambos, indicates the diversity between PD stimuli measures and perceived PD measures. At the same time, while the two Psychic Distance (PD) measures indicate high correlation in some cases, overall they are highly diverse from the CD measures. We argue, therefore, that identical studies could reach significantly different conclusions by simply using different measures of CD,pPD&PDs which then denotes significant implications for the reliability of research findings. Additionally, we point out potential weaknesses of these measures when examining culturally proximate countries and multicultural nations. 相似文献

This short note investigates the ability of Islamic banks (IBs) to play a leading role in revamping and driving conventional banking. To this end, we used a panel of 10 major conventional banks (CBs) and 10 IBs over the period 2006–2013. We applied panel regression tests and carried out a panel causality analysis. Our findings identified no significant causality effect from IBs to CBs and indicated that IBs are not able to play a role of leader. 相似文献
