Disasters are extraordinary situations that require significant logistical deployment to transport equipment and humanitarian goods in order to help and provide relief to victims. An efficient response helps to reduce the social, economic and environmental impacts. In this paper, we define and formulate a practical transportation problem often encountered by crisis managers in emergency situations. Since optimal solutions to such a formulation may be achieved only for very small-size instances, we developed an efficient genetic algorithm to deal with realistic situations. This algorithm produces near optimal solutions in relatively short computation times and is fast enough to be used interactively in a decision-support system, providing high-quality transportation plans to emergency managers. 相似文献

This paper addresses the heterogonous effects of adverse liquidity shocks on corporate cash holdings in an emerging market. We use a large panel dataset with quarterly financial information for Chilean firms during the period 1996–2009. We find three main results. First, liquidity crises have had a negative and economically significant effect on cash holdings, but mainly for small firms; medium‐sized and large firms have not been affected by liquidity crises. Second, liquidity crises reduce the ability of firms to adjust to optimal cash holdings. Finally, medium‐sized firms are less able to adjust cash holdings compared to small and large firms. 相似文献

The paper is a parametric and nonparametric analysis of past precipitation data. We analyze 90 years of daily precipitation data at the Sooke Reservoir in British Columbia, Canada, for evidence of climate change. We fit probability density functions (PDFs) to the data and find evidence of a structural break in the data generating process by using the Andrews-Ploberger test. To confirm this finding, we analyze higher moments of the distribution of precipitation and show that the PDFs have become more leptokurtic. The results show how the pattern of precipitation has changed. 相似文献

In spite of the rapid and large growth of niche tourism, and the proliferation of tour operators catering to such markets, limited information is available on the measurement of tour operator attributes that are critical to maximise the experience and needs of their tourists. Thus, a study was conducted to comprehensively evaluate different operational attributes of small storm-chasing tour operators. Findings reveal high internal reliability and utility for this niche market; additional testing is suggested to evaluate such scale among other small niche tourism operators. 相似文献

The concept of Orientalism has served to define post-colonial thinking, reflecting the West's interpretation of non-Western individuals and cultures. In this binary set, the West/us is approached as representing the standard, while the East/them represents that which is outside the norm. For the last few decades, Orientalism has continued to influence discussions in tourism studies; nevertheless, there is a dearth of empirical studies examining how the discourse lives out in daily tourism practices. Therefore, employing quantitative research methods, this study explores what Orientalism means to contemporary Americans and how it affects their attitudes toward Asian destinations. The result indicates that the imaginary construct of the East has reflected three different dimensions, namely contempt, curiosity, and fear, through which the Western world has traditionally framed the non-Western world; however, Americans generally believe that contemporary Asia cannot be adequately explained in these traditional and fixed ways. This study suggests that two terms, Asia and the East, connote very different meanings in contemporary American society, revealing how the traditional discourse of Orientalism is transformed and reinterpreted, although not totally changed, within the changing nature of the contemporary global environment. 相似文献

The Studi di Settore are used by the Italian tax administration to calculate reference revenue levels for small businesses and provide a kind of cut-off level for tax audits. Recently new rules have been introduced in order to render the Studi di Settore more efficient in producing realistic estimates, with the aim of reducing the “legalized evasion” that might arise in case of a systematic downward bias. Voices of the involved categories, however, convinced the Government to partially step back. Building upon the standard firm’s tax evasion model of Cowell [Cowell, F.A., 2004. Carrots and sticks in enforcement. In: Aaron, H.J., Slemrod, J. (Eds.), The Crisis in Tax Administration. The Brookings Institution, Washington DC, pp. 230–275] and the approach of Santoro [Santoro, A.C., 2006. Evasione delle società di capitali: evidenze empiriche e proposte di policy. In: Brosio, G., Muraro, M. (Eds.), Il Finanziamento del Settore Pubblico. SIEP, Angeli, Milano, pp. 163–186] we show that, under given conditions, a stringency increase might backfire implying a larger overall tax evasion and a smaller tax revenue. 相似文献

Despite the importance of the co-evolution approach in various branches of research, such as strategy, organisation theory,
complexity, population ecology, technology and innovation (Lewin et al., 1999; March, 1991), co-evolution has been relatively neglected in international business and ethics research (Madhok and Phene, 2001). The purpose of this article is to show how co-evolution theory provides a theoretical framework within which some issues
of ethics research are addressed. Our analysis is in the context of the contrasts between business systems (North, 1990), and in particular the distinction between informal systems and those systems where institutions are formalised in law.
This complements the growing research on comparative corporate governance and capitalisms (Chandler and Hikino, 1990; Choi et al., 1999; Whitley, 1994). The synthesis of co-evolution and analysis of divergent institutional environments in ethics research can also complement
the globalisation and MNE approaches to international business research. 相似文献

A new characterization of the Banzhaf semivalue on the domain of monotonic simple games is given. We use the well-known valuation
and dummy axioms plus two additional properties. The first one simply requires that the power-index be bigger for those players
belonging to more winning coalitions. The second one is the proportionality axiom introduced by Owen in (1982) which is suitable
for those simple games that represent an indirect voting process. 相似文献

This paper assesses the measurement errors inherent in segment reporting. Measurement errors are gauged by comparing the correlation
of segment results with their industry to the corresponding correlation for single line-of-business firms operating in the
same industry. The findings show that the measurement errors in segment information, particularly earnings, are larger than
those in the financial information reported by single line-of-business firms. The cross-sectional variation in the measurement
errors can be traced to cost/revenue allocations, management intervention in segment reporting, and the operational structure
of multi-segment firms. Market tests indicate that the information content of segment information is inversely related to
the estimated measurement errors.

An open debate these days is about how national income inequality could affect individuals’ health outcomes. Therefore, the present study aims to provide new evidence regarding life expectancy determinants and how they are related to the income inequality hypothesis. Precisely, it is provided new evidence on this relationship for 26 European countries during the period 1995–2014. The analysis is based on panel data techniques, with the latest data from both Eurostat and the OECD Health Statistics. Furthermore, data from the World Bank is also applied. Besides, we have tested the sensitivity of the estimates in our empirical analysis using three clusters of countries. Our results suggest that income inequality does not significantly reduce health in developed societies, like the European ones. Notwithstanding, as income inequality can be sometimes harmful for population health, these issues must be taken into account in order to improve health care policies. 相似文献
