Kaiser Permanente's manifesto 2005 demonstration: the promises and limits of devolution

In 1996, the eight-million member Kaiser Permanente HMO adopted a vision statement that said by 2005 it would expand its services to include home- and community-based services for its members with disabilities. It funded a 3-year, 32-site demonstration that showed that it was feasible to link HMO services with existing home-and community-based (HCB) services and that members appreciated the improved coordination and access. This private-sector project showed that devolution can produce innovative and feasible models of care, but it also showed that without federal financial and regulatory support, such models are unlikely to take hold if they are focused on "unprofitable" populations, for example, those who are chronically ill, poor, and/or disabled.     

The effects of coauthorship on the quality of financial research papers

This paper analyzes whether formal collaboration in terms of coauthorship enhances paper quality in financial research. Analyzing all papers presented at DGF annual meetings in the period from 1996 to 2005, we report the following major findings: First, we find superior paper quality of coauthored papers compared to single-authored papers. This holds true for two quality proxies, publication probability and publication quality (as measured by the original and the updated Jourqual rating). Second, the capability of scholars, measured by a citation measure derived from citations in Google Scholar, shows to be an additional important factor for explaining paper quality. Third, the employed methodology of a paper (e.g., empirical analysis, theoretical analysis) does not systematically affect paper quality. However, it is important to differentiate between empirical and theoretical papers. Whereas coauthorship shows to be a quality enhancing factor for empirical papers, this does not hold true for theoretical papers. Fourth, the origin of data is a crucial determinant of the publication success for empirical papers. In particular, papers which exclusively analyze data from Germany are published in less reputable journals.     

Technologiebasierte Spin-offs ?C Ein Forschungs??berblick zu Einflussgr??en ihrer Entwicklung

Technology-based spin-offs from academic institutions and private corporations represent an important proportion of young innovation-oriented ventures. They encounter specific starting conditions in terms of their core technology, the composition of the founding team, and the critical junctures during their establishment. This study analyses the state-of-the-art in quantitative empirical research on factors impacting the development of these types of firms. We present findings of both research fields and discuss them critically. Methodological and measurement issues receive particular attention in our analysis. Based on the literature review we identify factors impacting the development of both types of firms. Additionally we expose gaps in past and current research on academic and corporate spin-offs and suggest interesting opportunities for future research. Methodological shortcomings of existing studies are discussed. We derive implications for research on academic and corporate spin-offs and for the management of these types of firms.     

Management’s causal reasoning on performance and earnings management

We investigate the association between the intensity of causal reasoning on performance in a firm’s annual management commentary and its earnings management propensity. Anticipated earnings management concerns are argued to constitute a significant accountability predicament, bringing management to offer more intense causal reasoning in order to mitigate investors’ earnings management concerns. We use computer-intensive techniques to measure causal reasoning intensity as a generic disclosure quality in the management commentary of a large sample of US firms from 1999 to 2007. We find that accruals earnings management (signed discretionary accruals) is positively associated with causal reasoning intensity. The positive association holds for alternative specifications of accruals earnings management (an earnings management dummy model and an analyst expectations model) and in a change model. Our results are consistent with the assertion that firms strategically use causal reasoning on performance to establish appropriateness and cognitive legitimacy, increase perceived plausibility of reported performance and mitigate performance-related concerns of investors.     

Several recent Supreme Court decisions and their implications for political redistricting in Voting Rights Act context

This paper focuses on four recent United States Supreme Court decisions which have profound implications for political redistricting. These cases are Holder v. Hall, Johnson v. De Grandy, Shaw v. Reno and Miller v. Johnson. Each of these cases place limits on the scope of Section 2 of the Voting Rights Act when conducting a political redistricting or fashioning a remedy for a Section 2 violation. These cases have resolved a number of important issues in redistricting while creating yet new issues to be resolved. Although demographers are not in the business of practicing law, they must clearly understand the legal requirements and often subtle nuances imposed by the case law. The paper concludes that the combined force of these cases does not yet spell the end of race conscious redistricting and therefore, effectively repeal the Voting Rights Act but does require that more weight be given to traditional redistricting criteria when designing districts that will withstand legal challenges.     

Scenario Development for 2050 for the Israeli/Palestinian Water Sector

Scenario analysis suggests that by 2050 the population of Israel, the West Bank and Gaza will grow from its current 10 million to between 14 and 28 million. The scenarios developed are compared to available water resources and assessed for their viability. With all scenarios, except very high population growth in the context of inadequate co-operation between Israel and Palestine, the water resource needs of the entire population can be met. The analysis suggests that water need not be an obstacle to peace or economic development in the region.     

The Real Walmart

The Walmart Company is one of the favorite punching bags of market critics. They accuse this firm of underpaying employees, dealing unfairly with customers, exploiting suppliers, and bankrupting small competitors. Various political jurisdictions have banned this firm from their environs, either implicitly or explicitly. The present article offers a more nuanced position on the behemoth from Arkansas. Although it has some flaws, there is an overwhelming case to be made in its behalf as an employer, competitor, purchaser, benefactor of customers.
