Detecting alcohol abuse: the value of carbohydrate deficient transferrin

The author, an advocate of CDT testing for insurance applicants, senses considerable uncertainty among medical directors concerning the value of the test. This review of CDT literature and the history of CDT testing in insurance laboratories is an attempt to mitigate that confusion. Two principle problems are identified: 1) the expected sensitivity of the CDT test in insurance applicants will be 50% at most, usually considerably less. 2) adapting CDT testing to commercial laboratories has been, and still is, an unsolved problem for there remains an important disparity between the method used at Clinical Reference Laboratories and LabOne. Other important issues are also reviewed: gender differences, ethnicity, LFT's and CDT, and technical facts.     

Educating limited resource older adults for better choices to lower risk of food insecurity

United States (U.S.) national and North Carolina state data on older adult food insecurity in combination with associated poor nutrition‐related health outcomes point to a critical need for interventions to improve their food security. Nearly 8% of North Carolinians aged 60 and older and 11% of those aged 50–59 are food insecure, placing North Carolina in the top ten states in the U.S. for food insecurity for both age groups. Therefore, the Better Choices intervention was designed to educate limited‐income older adults in ways to manage their meager resources to purchase more and healthier foods. The purpose of this study was to determine the effectiveness of the Better Choices intervention in improving the knowledge, attitude, and behavior of participants concerning their food money resource management. Older adults (n = 453) with ages ranging from 59 to over 90 years participated in 8 weeks of educational programming delivered by educators in 15 participating North Carolina counties. In a cross‐over program design participating counties were randomly assigned to two groups, to create a control for the food money resource management treatment. A three‐points‐in‐time survey supported longitudinal measurement. Independent samples t‐tests showed no significant differences between groups at baseline. Paired sample t‐test results show the intervention was effective with statistically significant improvement of participants' knowledge regarding preparing a healthy meal on a budget, beans as a low‐cost alternative to meat, and the use of unit pricing to compare products to identify the best value. Participant‐developed action plans reflected planned behavior change. Study results show this group of older adults were capable of and willing to adopt new behaviors for a healthier lifestyle. While not a representative sample, the broad applicability of adult learning and planned behavior theories underpinning the program lead us to conclude that the methods and theories applied in this intervention should be of use to educators and practitioners serving limited‐resource older adult populations.     

A Markov switching analysis of contagion in the EMS

This paper applies the multivariate version of the Forbes and Rigobon (2002) contagion test, as proposed by Dungey et al. (2005a), to detect contagion effects in the Exchange Rate Mechanism (ERM) of the European Monetary System (EMS). Crisis and non-crisis observations are determined endogenously via a Markov-switching vector autoregression (MSVAR). We show that the MSVAR is suitable for this purpose, as it does particularly well in identifying the 11 realignments of the ERM. We examine whether Denmark’s rejection of the Maastricht Treaty and Italy’s competitiveness problems affected other EMS participants and find evidence for contagion.     

START FILLING YOUR TALENT GAP-NOW

As businesses steer their way out of turbulence, they have a unique opportunity to identify their leadership supply and demand and then to close the talent gap in their organization. Alan Bird, Lori Flees and Paul DiPaola explain how you can take immediate steps to build the right team now – and lay the groundwork for a long-term approach for nurturing talent within the organization.     

Defining the “global” in global leadership

While scholars have begun to develop the conceptual foundations of global leadership, few attempts have been made to unify the plethora of existing definitions. We argue that the lack of a precise, rigorous and commonly accepted definition of global leadership limits the field's conceptual and empirical progress. Building on recommended practice for construct definitions, we first review and critique existing definitions of global leadership. Second, we specifically focus on explicating the global construct encompassed by the global leadership phenomenon and propose three dimensions along which this sub-construct can be analyzed: complexity, flow, and presence. Finally, we offer a revised construct definition and conclude with implications for research and practice.     

Dual VATs and Cross-Border Trade: Two Problems, One Solution?

In recent years, two distinct but related questions have been raised with respect to value-added taxes (VATs). Concern has been expressed over whether it is desirable or even possible for both national and subnational governments in federal countries such as India, Argentina, and Russia to impose VATs. One reason for thinking that such subnational VATs are unlikely to be workable on a destination basis is the problem of cross-border trade. Of course, this same problem also arises within the European Union, where there is no EU VAT. Drawing upon Canadian experience, we argue that not only is it possible to have two-tier or dual VATs on a destination basis in a single country but that the existence of dual VATs may help deal with some of the problems of cross-border trade.     

THE WEALTH EFFECTS OF INCOME INSURANCE

Precautionary savings models suggest that wealth should rise with income risk. Risk is reduced by means-tested transfers, however, which implies that transfer programs should discourage private wealth accumulation. We offer a comprehensive empirical assessment based on variation across states in the generosity of a number of programs, specifically unemployment insurance and means-tested transfers (Aid to Families with Dependent Children and Food Stamps). We use monthly data on married couples from the Survey of Income and Program Participation (SIPP) to regress wealth on income, income risk, and various measures of transfer generosity. The results support the precaution-ary savings model and reveal moderate negative wealth effects of both unemployment insurance and means-tested transfers, with an elasticity of about −0.18.     

Mexico and the United States: Common border,common negotiating orientations

With a growing cadre of people conducting business across the U.S.–Mexico border, there is a need for information about the negotiation orientations they are likely to encounter. While information on negotiating orientations is available, it is often anecdotal, stereotyped, and contradictory. Empirical work that systematically compares Mexico and the United States across a range of negotiating dimensions is scarce. We have clarified, refined, and operationalized 12 negotiation dimensions in a comprehensive conceptual framework proposed over 20 years ago by Weiss and Stripp (1985). Our findings suggest that U.S. and Mexican negotiators may have more in common than they think and that negotiation orientations in both countries may run counter to conventional wisdom. © 2008 Wiley Periodicals, Inc.
