Visitor perceptions of crime-safety and attitudes towards risk: The case of Table Mountain National Park,Cape Town

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.     

Modelling international tourism and country risk spillovers for Cyprus and Malta

Small Island Tourism Economies (SITEs) are developing sovereign countries that rely on tourism as a source of exports, and need a consistent inflow of foreign investment in order to facilitate economic growth. Access to international capital markets helps SITEs smooth out their consumption over time, while absorbing adverse domestic production shocks. This paper provides a comparison of tourism growth, country risk returns and their associated volatilities (or uncertainty) for 2 SITEs, namely Cyprus and Malta. Monthly data are available for both international tourist arrivals and composite country risk ratings compiled by the International Country Risk Guide (ICRG) for the period May 1986 to May 2002. The time-varying conditional variances of tourism growth and country risk returns for the 2 SITEs are analysed using multivariate models of conditional volatility. Empirical results show that Cyprus and Malta are complementary destinations for international tourists. Changes to tourism patterns in Cyprus lead to changes to tourism patterns in Malta. Hence, tour operators and national tourism promotion authorities in Cyprus and Malta should collaborate closely in marketing and promoting joint tourism products. Moreover, foreign entities interested in investing in the tourism sectors of Cyprus and Malta should consider investment projects that span a long period of time. The performance of the tourism sector and the associated composite risk are independent of each other for the two countries. However, there is a direct relationship between the tourism sectors of Cyprus and Malta and their respective country risk settings.

A hybrid modeling approach for resilient agri-supply network design in emerging countries: Colombian coffee supply chain

Sustainability and resilience in Agri-Food Supply Chains is a challenging topic of current interest in the research community. Resilience for Agri-Food Supply Chain (AFSC) is the capability of the supply network to manage and mitigate disruptions due to global warming and natural phenomena such as landslides and floods of crops, among others caused by humans. A significant challenge is to design efficient and resilient AFSCs in emerging countries while perishability constraints are considered. A methodology to design an AFSC for emerging countries is addressed in this research. The phenomena that aid in identifying critical aspects of the AFSC affecting their resilience are identified. The former approach combines optimization and simulation schemes by considering resilience metrics related to availability and connectivity. Indeed, the solution approach addresses the uncertainty by using simulation of disruptive events and finding resilient designs using mathematical programming. The proposed framework has been evaluated in a Colombian coffee supply chain. The obtained results show the efficiency of the proposed scheme to design AFSCs and allow the practitioners to measure, predict, compare, and improve the level of resilience of their supply chains (SCs).     

The views of key stakeholders on an evolving food risk governance framework: Results from a Delphi study

Evidence of a decline in public trust associated with food risk governance over recent years has called into question the appropriateness of the current dominant risk analysis framework. Within the EU-funded SAFE FOODS project a novel risk analysis framework has been developed that attempts to address potential shortcomings by increasing stakeholder (including consumer) input, improving transparency, and formally incorporating benefit and non-health aspects into the analysis. To assess the viability of this novel framework, the views of food risk experts from the EU and beyond were sought using a distributed online questionnaire process called Delphi. In this paper the main results of this survey are described, revealing varying levels of support for the key innovations of the novel framework. Implications of our results for the new and old frameworks, for the future of risk analysis, and for the policy community more widely, are discussed.     

模型危机还是应用不当造成的危机?——对《高盛风险之海市蜃楼》一文批驳VaR模型之反驳

次贷风波所引起的金融危机不但使国际银行业一度岌岌可危,而且沉重打击了世界经济。作为市场风险管理的核心,Vag模型遭到各方诟病。通过分析《高盛风险之海市蜃楼》一文,本文归纳了对Vag模型的几点认识误区,包括忽略对外部数据准确性的考核与检验,在模型应用上未能对正常市场情况与极端市场情况区别对待等。本文进而论证Vag仍是当前风险管理的首选工具,提出对收益率概率密度分布的选择将是Vag模型进一步发展的核心与关键,强调数据分析,指出量化研究应作为主观判断的前提与基础等观点。     

后金融危机时期的金融创新策略与风险监管

金融创新与金融风险两者之间是一种相互促进、相互发展的关系。金融创新在为转移和分散金融风险做出了巨大贡献的同时也带来了新的风险。后金融危机时期我们不能停止金融创新的步伐,但一方面应注意处理好虚拟经济与实体经济的关系、处理好市场导向与加强监管的关系、处理好交易所市场与场外市场的关系;另一方面应通过实施有效的监管安排来防范和化解市场的宏观风险。     

基于经济资本管理的贷款系统性风险防范研究

在系统性风险防范的视角下,本文对经济资本管理的基本方法进行了重新梳理,发现现行的经济资本管理会导致亲周期效应问题,削弱其防范系统性风险的能力。为此,要在系统性风险防范目标下改进经济资本计量方法,以科学的系统性风险预测为基础确定经济资本限额,优化经济资本在行业和地区层面的分配,以及通过贷款集中度管理追求风险分散最大化,从而实现对系统性风险的有效防范。

应收账款成因与对策的理论研究

企业的资产质量是评价一个企业的重要指标,也是企业生存发展的重要保证。应收账款是企业的一项流动性较差的资产,分析应收账款形成原因是治理应收账款的重要前提,传统观点主要从扩大销售提高市场占有率方面对应收账款进行分析。本文结合经济发展的新形势从全新的角度对应收账款进行了分析,并据此提出了治理对策,以供探讨。
