This paper studies heritage tourism experiences in the postcolonial World Heritage Site of Saint Louis, Senegal. Based on fieldwork and archival research, it shows the complexity and discrepancy linked with heritage presentation and design from the experiential realities encountered on the ground. The argument put forward is that colonial heritage, although it is simplified and controlled to meet specific tourist expectations by official authorities, appears to be dynamic, performative and subject to multiple interpretations from visitors, tourist guides and local residents. It further suggests that social and economic conditions of the communities living in the site affect the heritage space and shape vicariously or directly tourists’ experiences, despite professionals’ efforts of keeping the heritage visible in certain ways. The article extends its discussion to adjacent topics of power and gender issues, demonstrating how heritage tourism in postcolonial African context is intimately intertwined with the changing everyday realities of the communities.  相似文献

This paper proposes a new theoretical framework for assessing the influence of risk in shaping the governance form in biopharmaceutical inter-firm relationships. In particular, we propose a multidimensional operationalization of relational and performance risk and, by following Transaction Cost Economics (TCE) and Real Options (RO) theory constructs, we hypothesize a relation between the aforementioned risk components and the choice of governance form. Specifically, following TCE reasoning, we hypothesize that a high level of relational risk leads towards more hierarchical governance forms, while, following RO theory, we hypothesize that a high level of performance risk leads toward market-oriented governance forms; finally, we hypothesize a moderating effect of each risk component on the other. We empirically test our framework through the analysis of 353 inter-firm relationships signed worldwide between pharmaceutical and biotech companies from 2007 to 2010. The results show substantive support for our theoretical framework. Furthermore, we find a significant moderating effect of the performance risk on the TCE relation between relational risk and governance forms.  相似文献

When are contrarian profits due to stock market overreaction?   总被引:30,自引:0,他引:30  
If returns on some stocks systematically lead or lag those ofothers, a portfolio strategy that sells 'winners' and buys 'losers'can produce positive expected returns, even if no stock's returnsare negatively autocorrelated as virtually all models of overreactionimply. Using a particular contrarian strategy we show that,despite negative autocorrelation in individual stock returns,weekly portfolio returns are strongly positively autocorrelatedand are the result of important cross-auto-correlations. Wefind that the returns of large stocks lead those of smallerstocks, and we present evidence against overreaction as theonly source of contrarian profits.  相似文献

In this article we test the random walk hypothesis for weeklystock market returns by comparing variance estimators derivedfrom data sampled at different frequencies. The random walkmodel is strongly rejected for the entire sample period (1962-1985)and for all subperiods for a variety of aggregate returns indexesand size-sorted portfolios. Although the rejections are duelargely to the behavior of small stocks, they cannot be attributedcompletely to the effects of infrequent trading or time-varyingvolatilities. Moreover, the rejection of the random walk forweekly returns does not support a mean-reverting model of assetprices.  相似文献

Abstract

The purpose of this study is to examine the information search behavior of Hong Kong's inbound tourists, in particular business and leisure travelers. The study clearly shows that business and leisure travelers demonstrate different information search behavior. ‘Personal experience,’ ‘Travel agency/tour company,’ ‘Airlines’ and the ‘Internet’ are most frequently relied upon by business travelers in searching for travel information, while leisure travelers prefer ‘Travel agency/tour company,’ ‘Friends or relatives,’ ‘Travel guide books,’ and ‘Personal experience.’ The study also reveals that the total number of information sources used and the length of pre‐trip planning lead‐time are significantly different between these two groups of travelers. First time travelers also have a longer pre‐trip planning lead‐time than repeat travelers. Furthermore, business and leisure travelers perceive the levels of influence of several information sources, including ‘Corporate travel departments,’ ‘Friends or relatives,’ ‘Travel guide books,’ and the ‘Internet,’ differently. These information sources were classified into five different dimensions, including ‘Media,’ ‘Neutral,’ ‘Retail,’ ‘Interpersonal,’ and ‘Personal experience.’ Analysis based on travelers' purpose for traveling and demographic information was performed. Leisure travelers perceive the level of influence of ‘Neutral’ sources as significantly higher, and those with lower household incomes perceived the level of influence of ‘Personal experience’ as lower. The results of this study will allow marketers in Hong Kong to better understand travelers’ information search behavior so that they can more effectively tailor their marketing strategies to these two major markets.  相似文献

We examine the implications of portfolio theory for the cross-sectionalbehavior of equity trading volume. Two-fund separation theoremssuggest a natural definition for trading activity: share turnover.If two-fund separation holds, share turnover must be identicalfor all securities. If (K + 1)-fund separation holds, we showthat turnover satisfies an approximately linear K-factor structure.These implications are examined empirically using individualweekly turnover data for NYSE and AMEX securities from 1962to 1996. We find strong evidence against two-fund separation,and a principal-components decomposition suggests that turnoveris well approximated by a two-factor linear model.  相似文献

Using the decision- and experiential-oriented perspectives as theoretical guides, this article reported an empirical assessment of service quality in restaurant operations. We proposed and tested a conceptual model of service quality using structural equation modeling. Using data from a sample of 284 customers from two large full-service restaurants in southern China, we investigated the relationships of service quality, customer satisfaction, and frequency of patronage. The results supported the significant links between service quality and customer satisfaction, service quality and repeat patronage, but not customer satisfaction and repeat patronage. The study has provided important insights into service quality and customer satisfaction in the field of restaurant operations.  相似文献
