Only recently have researchers begun to study the causes of crime in tourist destinations, particularly in those areas which offer casino gaming. Critics, who cite the high crime rates of Atlantic City, New Jersey and Las Vegas, Nevada, fail to understand the relationship between tourism and crime. Casino gaming is a catalyst for tourism and one of the social consequences of tourism is increased crime.The mean crime rates of three tourist areas (including Atlantic City) and two urban centers in New Jersey were examined to determine if the rates were significantly different. Additionally, the study examined and identified which types of crime have changed since the advent of tourism in Atlantic City.Policy makers who reject gaming in favor of other mechanisms for urban revitalization need to take note. Tourist destinations have mean crime rates significantly different (higher) from urban areas, at least in New Jersey. Gaming-free tourism initiatives will have similar consequences for a community, as gaming has been identified to have had on Atlantic City. 相似文献

Methods for constructing confidence intervals for variance component ratios in general unbalanced mixed models are developed. The methods are based on inverting the distribution of the signed root of the log-likelihood ratio statistic constructed from either the restricted maximum likelihood or the full likelihood. As this distribution is intractable, the inversion is rather based on using a saddlepoint approximation to its distribution. Apart from Wald's exact method, the resulting intervals are unrivalled in terms of achieving accuracy in overall coverage, underage, and overage. Issues related to the proper “reference set” with which to judge the coverage as well as issues connected to variance ratios being nonnegative with lower bound 0 are addressed. Applications include an unbalanced nested design and an unbalanced crossed design. 相似文献

Robert Nisbet returned to full time teaching at the University of California, Riverside, in 1964, after ten years as Dean and Vice-Chancellor. The author was an undergraduate student in sociology at Riverside during the years 1965-67 and recalls Nisbet as a teacher. This was a prolific period in Nisbet’s writing career and many of the ideas that appeared in his books were introduced and explored in the courses that he taught. Two of these courses – “Community” and “History and Systems of Sociology” – are discussed in detail. The presentation of the material in these courses provides insight into how Nisbet understood the themes of the sociological tradition and how he thought these were best communicated to students. The paper also considers how Nisbet, an avowed conservative, was perceived by some of his undergraduate students during a time of cultural ferment and political unrest in America. 相似文献

An approximation to the exact distribution of the Wilcoxon rank sum test (Mann-Whitney U-test) and the Siegel-Tukey test based on a linear combination of the two-sample t-test applied to ranks and the normal approximation is compared with the usual normal approximation. The normal approximation results in a conservative test in the tails while the linear combination of the test statistics provides a test that has a very high percentage of agreement with tables of the exact distribution. Sample sizes 3≤m, n≤50 were considered. 相似文献

We examine the effect of nonnormality on the distributions of near-replicate lack-of-fit F-tests. We show that when the number of clusters is large, the distributions of the lack-of-fit tests depend on the kurtosis of the error distribution, and that heavy-tailed error distributions can inflate significantly the sizes of the tests. This behaviour is also evident in small samples, where some lack-of-fit tests are clearly more affected than others by nonnormality. Two modifications of the F-tests are suggested to eliminate the effect of the kurtosis on the limiting null distributions, and their behaviour is studied for small samples. 相似文献

Soaring food and energy prices sparked the revolts in Northern African countries at the end of 2010. This article investigates empirically the impact of world food prices on inflation and government subsidies for Algeria, Egypt, Israel, Jordan, Lebanon, Morocco, the occupied Palestinian territories and Tunisia during the ten‐year period 2002–11. Its findings reveal an asymmetry in the response of consumer‐price inflation to shocks in world food prices that made inflation rise fast while nominal rigidities prevented it from falling. Moreover, it shows that government balances deteriorated to 2% of GDP in 2008 and 2011 owing to the incremental government food subsidies, while they hardly improved in value terms when world prices fell sharply in 2009. 相似文献
