STATE DRUG CONTROL SPENDING AND ILLICIT DRUG PARTICIPATION 总被引:1,自引:0,他引:1
The purpose of this article is to estimate the effect of state criminal justice expenditures and state public health expenditures on deterring illicit drug use. The empirics are based on a demand-and-supply model of drug markets. The effect of a given expenditure on criminal justice or public health programs is dependent on the magnitude of the resulting shifts in the two functions and the demand price elasticity. A reduced form of the demand-and-supply model is also estimated. The data employed come from the 1990 and 1991 National Household Surveys on Drug Abuse (NHSDA). Data on state and local spending for drug-related criminal justice and drug-related public health programs were merged with the NHSDA. The main findings from the regression results are that drug control spending reduces drug use. However, the results suggest that for marijuana users, the marginal cost of drug control exceeds the social benefits of drug control. This may not be the case for users of other illicit drugs. Spending for drug enforcement by police and drug treatment is found most effective in deterring drug use. However, spending for correctional facilities is never significant, which suggests that a more efficient method of reducing drug use might be to reduce correctional facilities spending and increase spending on treatment. 相似文献

Self-employment rates and project size vary greatly across countries. The main message of this paper is that these broad regularities are consistent with an environment in which a common self-employment technology is available worldwide, but where (a) financial intermediation costs and (b) alternatives in “paid” work differ greatly. Our model indicates that alternatives in paid work are crucial for explaining self-employment rates, whereas high financial intermediation costs primarily affect the scale of projects. We also show that credit use is not informative for predicting either rates of self-employment or the scale of self-employment projects. 相似文献

Like any value‐creating staff function, HR departments should operate as a business within a business. Others have focused on the strategy and direction of HR departments. This article examines the next evolution for how HR department organization structure can deliver value based on two premises: (1) HR organization should be structurally aligned with the organization structure of the business and (2) because diversified/allied business models prevail, it is important to lay out the five roles and responsibilities of HR that respond to this organization model: service centers, corporate, centers of expertise, embedded HR, and operational HR. The article lays out the duties of each role, the relationship among these roles, and suggestions for implementing this new HR structure. © 2008 Wiley Periodicals, Inc. 相似文献

Shopping format choice has been an interesting and important area of research in the academic literature from long time. However, research in this area is presently at a nascent stage in India. There are a very few studies which focus on store format choice in India which includes the works of Anand and Sinha (2009), Prasad and Aryasri (2008), Sinha and Banerjee (2004) and Tripathi and Sinha (2008). The present study compares three different retail formats (Discount stores, Exclusive stores and Multi-brand outlets) based on the shopper's perception of relationship quality (RQ) of these stores using multivariate techniques. For addressing, the objective of this study a sample of 313 shoppers is used. Results suggest that “conflict due to store” and “combined overall RQ due to the store and its employees” influence the store format choice. The RQ levels among the apparel store format are highly competitive. 相似文献

Customer expectations form the standards against which organisation performance is often assessed. Additionally, knowledge relating to customer expectations provides information concerning the differentiated performance requirements of heterogeneous customer groups. Relatively few studies have explored the segmentation potential of ‘customer expectations, und to the best of this author. knowledge, none of these has addressed the issue it1 the non-profit sector. This study addresses this need by investigating the extent to which demographics constitute expectation segmentation criteria in the context of the police service. Both the desired and predictive expectation standards are considered. Managerial arid research implications are given. 相似文献

We adopt realized covariances to estimate the coefficient of risk aversion across portfolios and through time. Our approach yields second moments that are free from measurement error and not influenced by a specified model for expected returns. Supporting the permanent income hypothesis, we find risk aversion responds to consumption-smoothing behavior. As income increases, or as the consumption-to-income ratio falls, relative risk aversion decreases. We also document variation in risk aversion across portfolios: risk aversion is highest for small and value portfolios. 相似文献

In recent years numerical investigations of tsunami wave propagation have been spurred by the magnitude 9.3 earthquake along the Andaman–Sumatra fault in December, 2004. Visualization of tsunami waves being modeled can yield a much better physical understanding about the manner of wave propagation over realistic seafloor bathymetries. In this paper we will review the basic physics of tsunami wave propagation and illustrate how these waves can be visualized with the Amira visualization package. We have employed both the linear and nonlinear versions of the shallow-water wave equation. We will give various examples illustrating how the files can be loaded by Amira, how the wave-heights of the tsunami waves can be portrayed and viewed with illumination from light sources and how movies can be used to facilitate physical understanding and give important information in the initial stages of wave generation from interaction with the ambient geological surroundings. We will show examples of tsunami waves being modeled in the South China Sea, Yellow Sea and southwest Pacific Ocean near the Solomon Islands. Visualization should be a part of any training program for teaching the public about the potential danger arising from tsunami waves. We propose that interactive visualization with a web-portal would be useful for understanding more complex tsunami wave behavior from solving the 3-D Navier–Stokes equation in the near field. 相似文献

Canned food once represented an astonishingly innovative technology although it is now largely ignored in food discourse. As with so much in our lives, familiarity renders an object invisible. To explore the changing social significance of canned food, as the format developed from scientific curiosity to domestic ubiquity, this paper examines reports in The Scotsman newspaper from the late 1870s to the 1930s. Although canned foods were slow to break into the mass market they were little short of revolutionary in the way they brought new tastes from across the world to ordinary British households. A few cans in the larder provided simple storage and reassurance that the unexpected visitor could be fed – perhaps with something a little out of the ordinary. Against this background of quiet assimilation into our food culture, canned food has been controversial and provided an unwitting rehearsal for contemporary food narratives. In these old newspapers, it was somewhat surprising to find reports of disquiet that are recognizable in our own times – the convenience of canned food posed a threat to culinary skills; questions were raised about the nutritional value and safety of processed food; we had become excessively reliant on imported food and disregarded our own produce. 相似文献
