Visitor management plans are increasingly seen by local authorities as an essential contribution they can make towards sustainable tourism. However, tourism is subject to many external influences and is only part of the system of activities and land uses at the destination. Successful visitor management must, therefore, be broadly based and rooted in a wide range of policies. The objectives for sustainable tourism in Cambridge are supported by policies at the European, national, regional, county and local level covering tourism, recreation, transport, the environment, land use and economic development. This results in an integrated policy framework that ensures consistency, encourages cooperation and long‐term planning, makes the best use of resources, opens up additional sources of finance and provides a firm justification for refusing undesirable development. Achieving integration requires the visitor management plan to be seen neither as an end nor as a beginning, but as part of a process. In Cambridge this has involved a commitment to monitoring and reviewing strategies and to ensuring a policy input on tourism issues at all levels of decision making. Appropriate ad hoc bodies have been set up. Visitor management cannot succeed in isolation: other policies must be made to work for it, not frustrate action.  相似文献

This paper explores the burden of racial harassment and abuse on Britain's black footballers and places this in the context of leisure time racism. It is based on research carried out between 1989 and 1994. It is suggested that the source of such racism has been a neglected issue and only gained significant recognition in 1993 when the Commission for Racial Equality launched its Let's Kick Racism Out of Football campaign. It is argued that the racial abuse and chanting aimed at black footballers are examples of racial harassment. The research gathered evidence from two locations - Leeds and Newcastle - to assess the extent to which players were being disproportionately affected by this harassment and introduces the concept of 'burden of abuse'. Some historical background is provided and football stadia are considered as key symbolic leisure sites where a basic white working class racism has found expression. The growth of black footballers since the 1970s is considered, as well as the way such players have survived the racial harassment, some of whom were interviewed as part of the research exercise.  相似文献

This article considers how directors' remuneration should be set. It does so in both general terms and in the light of the DTI (1999) paper entitled Directors' Remuneration. A Consultative Document . The DTI document forms part of a general review of company law that is being undertaken by the Department of Trade and Industry. This article explores the extent to which these government-directed developments can be seen as an extension of the Cadbury, Greenbury and Hampel Reports and the extent to which self-regulation as opposed to government regulation looks set to dominate this area.  相似文献

The authors take a critical view of the investment approach advocated by recent Nobel laureate Robert Shiller. A critic of efficient markets theory, Shiller has proposed that investors, when attempting to determine whether the S&P Index is under‐ or overvalued, should use a P/E ratio whose denominator is the 120‐month moving average of the company's EPS. But the authors find that such an approach does not provide consistently superior insights to those provided by conventional PEs—and that, for example, the use of both conventional and Shiller PE multiples would have indicated a highly overvalued S&P not only in early 2000—before the bursting of the dotcom bubble—but also in 1996, when Fed Governor Greenspan spoke prematurely of “irrational exuberance.” The authors also show that both the Shiller PE and the conventional PE ratios fail a critical statistical test: they are not mean‐reverting—and as a consequence, both ratios can be expected to indicate either undervaluation or overvaluation for very long periods of time. Complicating matters, current earnings are useful to investors in predicting future stock prices only insofar as they provide a reliable guide to future earnings and cash flows. And as one would expect in competitive capital markets, even perfect foreknowledge of future earnings is not likely to be much help since, according to the authors' analysis, five‐year earnings explain on average less than 20% of the variation in prices over consecutive five‐year periods.  相似文献

Prior work has examined the effects of absolute levels of outside director stock option grants on risk behavior without recognizing that relative stock option values could differentially affect risk taking. Drawing from the house money effect perspective, we extend this literature by examining how positive deviation from prior outside director option grants values influences firm strategic risk. Additionally we draw from the behavioral agency model and the power literature to develop a multiagent contingency framework suggesting the effect of positive director pay deviation depends on the incentives and power of CEOs reflected in CEO stock ownership and CEO duality, respectively. Our empirical results indicate positive pay deviation has a positive effect on firm risk taking while high ownership and duality independently and jointly weaken this base relationship.

This paper investigates the role played by the social media platform Reddit in the events around the GameStop (GME) share rally in early 2021. In particular, we analyze the impact of discussions on the r/WallStreetBets subreddit on the price dynamics of the American online retailer GameStop. We customize a sentiment analysis dictionary for Reddit platform users based on the Valence Aware Dictionary and Sentiment Reasoner (VADER) sentiment analysis package and perform textual analysis on 10.8 million comments. The analysis of the relationships between Reddit sentiments and 1-, 5-, 10-, and 30-min GameStop returns contribute to the growing body of literature on “meme stocks” and the impact of discussions on investment forums on intraday stock price movements.  相似文献

A genre is a category of texts marked out by the conventions employed in their production. A genre-theoretic approach draws out the complex, subtle and elusive nature of financial reporting as communication. It provides scope for examining the features of the reporting process that contribute to its complexities and subtleties in a systematic, comprehensive and integrated way, embracing both technical and social dimensions. This paper discusses aspects of genre theory, as employed in discourse analysis, and their application to financial reporting. Relevant features of the approach include financial statement composition as a challenging process; knowing users; an engaged discourse community; situated communication; intertextuality; and structural dynamism. A genre-based approach has a number of implications for financial reporting research, at both methodological and substantive levels, which are explored in the paper, and may ultimately offer the potential for integrating market-based and interdisciplinary work together with the best of the classical tradition.  相似文献

Challenging anticompetitive acquisitions of nascent competitors is a top priority of the Antitrust Division of the U.S. Department of Justice. It is especially important that competition agencies remain vigilant of such acquisitions in platform markets, where indirect network effects and other market forces tend to preserve the status quo at the expense of smaller, more innovative rivals and potentially final consumers. This article discusses two such attempted acquisitions: (1) Visa’s acquisition of technology firm Plaid that threatened to disrupt Visa’s monopoly power in online debit; and (2) Sabre’s acquisition of Farelogix, which is a firm that allows airlines to connect directly to travel agencies and thereby disintermediates Sabre and other global distribution systems.

We propose a simple method to infer the forecast error associated with quarterly estimates of earnings and revenue before the firm announces realized earnings and revenue. The method uses estimates of the profit margin implied by an analyst’s forecasts of both earnings and revenue to identify forecasts that are likely to be optimistic or pessimistic. The ability to anticipate forecast error permits a trading strategy that exploits the average market reaction following positive and negative earnings and revenue surprises.  相似文献
