Visitor perceptions of crime-safety and attitudes towards risk: The case of Table Mountain National Park,Cape Town 总被引:1,自引:0,他引:1
This paper investigates tourist perceptions of crime-safety and attitudes towards risk whilst visiting Table Mountain National Park (TMNP) in Cape Town in June and July 2008. The study examined survey data of 303 domestic and international tourists during their visit to TMNP. A linear regression analysis revealed that although visitors had concerns about their personal safety they are still likely to return to TMNP and recommend it to other people. In addition, visitor attitudes towards risk did not influence perceptions of crime-safety and its effect on their intentions to revisit or recommend TMNP. The results also show that respondent's individual characteristics such as age, nationality, and purpose of visit influenced their perceptions of crime-safety. Perceptions that TMNP is unsafe tended to increase with respondent's age. Respondents on holiday were more likely to perceive TMNP as safer than those on business or visiting friends and relatives. The study's findings add to the literature by offering more insight on tourist perceptions of crime-safety and attitudes towards risk and their impact on tourist behaviour. Various tourist-crime prevention measures to enhance visitor safety at national parks are also recommended to the tourism industry and law enforcement agencies. 相似文献

The conjuncture that ushered in the era of shareholder value served to embed capital market expectations into corporate governance aligning management and shareholder interests. Market arbitrage focussed on modifying contractual relations with stakeholders to extract a (higher) return on invested capital. In this article we focus on cash earnings on capital employed generated by the S&P 500 survivor group of firms covering the period 1990–2008. We use this financial data to construct three complementary perspectives on corporate financial performance: firm, firm-relative and macro. Within this framework the financial numbers and perspectives are analogous to a ‘hall of mirrors’ where ambiguity and contradiction are in play frustrating straightforward performative narratives that connect purpose with financial transformation an era of shareholder value. 相似文献

We introduce and study the f0-relevance property of a coherent measure of risk on a positions vector space with vector ordering. We show that it is equivalent to a special no arbitrage condition on bounded positions spaces. Continuity from below leads to representations of f0-relevant coherent measures of risk based on equivalent functionals in Banach subspaces of the order dual. We define and describe f0-martingales in a lattice, and present a solution to the hedging price problem: the asset price process is an order convergent f0-martingale. Under the f0-relevance hypothesis we study the relationship between worst conditional mean and value at risk. 相似文献

Major donations, especially for endowed chairs, put Colleges of Business and Universities in the spotlight and create a great
deal of excitement, highlighting the important role that educational institutions play in benefiting the students, the community,
and society in general. This kind of excitement needs to be sustained over time, signifying the link that the endowed Chair
or Professorship in Entrepreneurship creates between the past, the present, and the future. Consequently, there is a need
for a long-term personal connection and close relationship between the donor, the faculty holding the endowed chair, and the
institution represented by the Dean that should be preserved over time. This study reports findings of a survey of the perceptions
of AACSB Deans on what an Endowed Chair in Entrepreneurship is, and what it could, and should mean for their institution. 相似文献

Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the high-inflation steady state. These paths are shown to be stable under least-squares learning if agents can utilize contemporaneous data. In an economy with a mixture of agents, some of whom only have access to lagged data, stable hyperinflationary paths emerge only if the proportion of agents with access to contemporaneous data is sufficiently high. 相似文献

We consider time series forecasting in the presence of ongoing structural change where both the time series dependence and the nature of the structural change are unknown. Methods that downweight older data, such as rolling regressions, forecast averaging over different windows and exponentially weighted moving averages, known to be robust to historical structural change, are found also to be useful in the presence of ongoing structural change in the forecast period. A crucial issue is how to select the degree of downweighting, usually defined by an arbitrary tuning parameter. We make this choice data-dependent by minimising the forecast mean square error, and provide a detailed theoretical analysis of our proposal. Monte Carlo results illustrate the methods. We examine their performance on 97 US macro series. Forecasts using data-based tuning of the data discount rate are shown to perform well. 相似文献

County officials in the seven-county metropolitan area of the State of Minnesota's Twin Cities of Minneapolis and St Paul were seeking to redefine county roles in service delivery. This article reports on a process model that was piloted on two services. The model was commissioned by officials; was based upon and informed by literature and comparative experience; began with an examination of functions performed; involved participants in focusing the study; was context-focused; and involved local stakeholders in projecting the implications of alternative county roles. These characteristics complicated the research management process because the process took more time, involved more actors, and required more coordination than traditional research. However, having stakeholders identify alternatives and bring factual material to the process was critical to the success of the model and including the comparative and contextual research both strengthened the policy conclusions and improved the probability of their adoption and implementation. A case of a Minnesota county that followed the model in an effort to reform water governance within the county illustrated adoption of the approach. The stakeholder analysis process was previously applied in Africa, China and Southeast Asia and the model should be applicable to a wide range of settings and problems. 相似文献

Technical progress lowers costs and prices but appears to have an ambiguous effect on product reliability. This paper presents a simple model which explains this observation. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

This paper proposes a trustable mold redesign knowledge-sharing platform, known as CKshare, based on private cloud and blockchain technology. Firstly, we use private cloud to store the mold redesign knowledge of each party to meet its own privacy and data format requirements. Secondly, a blockchain network is used for recording the knowledge and its transactions to ensure security and trustfulness. Thirdly, a simple retrieval mechanism is developed based on k-nearest neighbors for retrieving the codified knowledge on the platform. To realize CKshare, a prototype platform has been developed and explained based on real data from the case mold company. 相似文献
