‘Accueil’ is a French word that means feeling welcome somewhere and being introduced into a process that takes the visitor from being an outsider (a stranger) to being an insider (one of us). Accueil also means feeling the host’s genuine pleasure in welcoming his or her guests through words, attitudes, and actions. Based on a survey (n = 1,003) done for the Quebec Department of Tourism1, we look at how different segments of visitors perceived the ‘accueil’ they received while traveling in the province of Quebec. The results are analysed for lodging, restaurants and attractions. We found that accueil is perceived differently depending on the age of the visitor, the group size and its composition. To a lesser extend, it is also influenced by gender and social status. The characteristics of the trip (distance, purpose and length) have little impact on accueil.  相似文献

This paper presents a harmonized data set over the period 1972–2002, containing two-yearly data on the number of non-agricultural business owners and the size of the labour force for 23 OECD countries, as well as the quotient of these two variables which is called the business ownership rate of a country. The data set is called COMPENDIA, which means COMParative ENtrepreneurship Data for International Analysis. It has been constructed by EIM Business and Policy Research, using OECD statistics as well as other relevant sources. We make an attempt to make business ownership rates comparable across countries and over time.  相似文献

Social media outlets constitute excellent vehicles for fostering relationships with customers. One specific way to do this is to create brand fan pages on social networking sites. Companies can place brand posts (containing videos, messages, quizzes, information, and other material) on these brand fan pages. Customers can become fans of these brand fan pages, and subsequently indicate that they like the brand post or comment on it. This liking and commenting on brand posts reflects brand post popularity. In this article, we determine possible drivers for brand post popularity. We analyze 355 brand posts from 11 international brands spread across six product categories.Results show that positioning the brand post on top of the brand fan page enhances brand post popularity. But the findings also indicate that different drivers influence the number of likes and the number of comments. Namely, vivid and interactive brand post characteristics enhance the number of likes. Moreover, the share of positive comments on a brand post is positively related to the number of likes. The number of comments can be enhanced by the interactive brand post characteristic, a question. The shares of both positive and negative comments are positively related to the number of comments. Managers of brands that operate brand fan pages can be guided by our research with regards to deciding which characteristics or content to place at brand posts.  相似文献

The purpose of socially responsible investing (SRI) is to: (1) allow investors to reflect their personal values and ethics in their choices, and (2) encourage companies to improve their ethical, social, and environmental performance. In order to achieve these ends, the means SRI fund managers employ include the use of negative screening, or the exclusion of companies involved in “sinful” industries. We argue that there are problems with this methodology, both at a theoretical and at a practical level. As a consequence, current SRI offerings cannot accurately reflect the values and ethical beliefs they propose to represent. Moreover, the use of a␣priori criteria is potentially misleading, as we show by discussing examples of glue and wine making. Applying this flawed approach SRI funds fail to influence the direction of the firms they deem most in need of re-directing. Rather than engaging in the simple a␣priori assumption that some industries are “saints” while others are “sinners” (Freeman, 2007) we suggest a new framework upon which the SRI screening methodology could be grounded. Embracing the philosophical tradition of American pragmatism, we suggest that SRI methodology could be improved by engaging in an analysis based on (1) the actual impacts of the company’s products and services, (2) the company’s relationships with its specific, real stakeholders, and (3) the contingent environment (social, economic, political, legal, and cultural) in which the business operates.  相似文献

This article proposes a systematic approach to evaluating the performance of national statistical systems. Its starting point are the so-called Fundamental Principles of Official Statistics, which were adopted by the United Nations some time ago. The aim is to translate the principles into operational terms and concrete questions about 'how we are measuring up'.  相似文献

In a bankruptcy problem framework we consider rules immune to possible manipulations by the creditors involved in the problem via merging or splitting of their individual claims. The paper provides characterization theorems for the non manipulable rules, the no advantageous merging parametric rules and the no advantageous splitting parametric rules.

Alliances arise in a wide variety of domains, when a group of countries, political parties, people or other entities agree to work together because of shared interests or aims. They make sense, if the output obtained is somehow better than the outcome of acting individually. Revenue or cost sharing is key when determining if individuals are better off by contributing to an alliance or not. In our alliance each member owns a unique resource –or set of resources–, which is given to the alliance. The alliance sells services, which are supported thanks to one or a set of these resources. We focus on alliances that sell services in such a way that the total revenue of the alliance is maximized. We show that this kind of problems can be modeled through a Network Utility Maximization problem. We subsequently explore the problem of revenue sharing among the members of the alliance. Such a problem is a complex one since the interests of all participants must be ensured and correct incentives must be provided. We formally formulate the members’ interests through a set of properties the revenue sharing method should verify. We then discuss the existing methods for revenue sharing and conclude that none of them verifies the needed properties for the case of a revenue maximizing alliance. We finally propose a revenue sharing method based on projecting the contributions of each member of the alliance into an economic stable set. Through an exhaustive simulative study we conclude that our method provides, in addition to economic stability, fairness among members and the right incentives to them. Through our analysis Network Service Provider alliances, which sell quality-assured data transport services, are considered as an application example.  相似文献
