Voluntary and involuntary driving cessation in later life

This study explores the decision-making process of driving cessation in later life, with a focus on voluntariness. The sample included 83 former drivers from the Baltimore Epidemiologic Catchment Area Study. A majority of participants (83%) reportedly stopped driving by their own decision. However, many voluntary driving retirees reported external factors such as financial difficulty, anxiety about driving, or lack of access to a car as main reasons for driving cessation. These findings imply that distinction between voluntary and involuntary driving cessation is ambiguous and that factors beyond health status, including financial strain, play a role in the transition to non-driving.     

Barriers to evidence based practice in accommodations for an aging workforce

According to a recent Government Accountability Office report, the number of workers over age 55 is projected to increase significantly over the next twenty years, with this demographic group projected to comprise as much as twenty percent of the workforce by 2015 [12]. Accommodating the functional limitations of a large number of older workers may prove challenging for employers; however, policies and practices shaped over the course of the next few decades could allow aging workers to remain a valuable part of the US economy. Given these considerations, it is useful from a public policy perspective to determine the degree to which employers are currently addressing the accommodation needs of older workers. This paper presents the results of a study that attempted to determine the extent to which a sample of Fortune 500 employers was currently accommodating older workers. The study's methodology (in particular, its use of semi-structured telephone interviews) is reevaluated and new options (such as anonymous online employer surveys) are considered for the valid and reliable collection of data on accommodations for older workers.     

Employee Volunteering and Social Capital: Contributions to Corporate Social Responsibility

As employee volunteering (EV) is increasingly regarded as a means of improving companies' community and employee relations, we investigate the contribution of EV to corporate social responsibility, specifically whether and how it contributes to social capital. We investigate the dynamics of EV in three UK companies. We explore the social relations and resources which underpin social capital creation; the roles of opportunity, motivation and ability in bringing the actors together and enhancing their capacity for cooperation; and the ways in which alternative EV modes inform the different dimensions of social capital – networks, trust and norms of cooperation. Our paper contributes to our understanding of EV and the factors that enable it to create social capital. Finally we assess the contribution of EV to the overall corporate social responsibility agenda of companies.     

LM Test of Neglected Correlated Random Effects and Its Application

This article aims at achieving two distinct goals. The first is to extend the existing LM test of overdispersion to the situation where the alternative hypothesis is characterized by the correlated random effects model. We obtain a result that the test against the random effects model has a certain max-min type optimality property. We will call such a test the LM test of overdispersion. The second goal of the article is to draw a connection between panel data analysis and the analysis of multiplicity of equilibrium in games. Because such multiplicity can be viewed as a particular form of neglected heterogeneity, we propose an intuitive specification test for a class of two-step game estimators.     

News and information leadership in the digital age

This paper examines information networks on social media to draw conclusions about influence relationships among members of the mass media. The project considers social networks and information patterns using Twitter data, first at the newspaper level and second at the journalist level. Using a computational approach, we look for evidence of elite-directed information flows, as well as exploring whether we find evidence of an increase in the democratization of newsmaking. This study finds that elite voices continue to dominate information networks in the digital age; however, it also finds evidence that information can move expeditiously from journalists in local and regional outlets to elite ones, and vice versa. We move further to explore the content of tweets among the journalist network, finding that there are substantial, direct interactions among elite and regional and local journalists. Our results taken together uncover new network patterns and provide a novel insight on the role of information technologies in newsmaking in the digital age.     

The Effects of Social Comparison and Objective Feedback on Work Performance Across Different Performance Levels

This study investigated the interaction effects of feedback content type (social comparison feedback vs. objective feedback) and two different performance levels (high vs. low) on work performance. One hundred fifty participants were recruited and asked to perform a simulated work task in a preliminary session. Based on their performance, the upper 40% (high performance) and lower 40% (low performance) groups were selected for the main experiment. Participants in each group were randomly assigned to the two different experimental conditions: objective feedback and social comparison feedback. For the participants in the objective feedback condition, information on the number of correctly completed work tasks was provided. For the participants in the social comparison feedback condition, rank information on their performance was provided. The results indicated that social comparison feedback was more effective than objective feedback for the high performers, but was less effective for the low performers.     

Lambda number for the direct product of some family of graphs

An L(2, 1)-labeling for a graph \(G=(V,E)\) is a function f on V such that \(|f(u)-f(v)|\ge 2\) if u and v are adjacent and f(u) and f(v) are distinct if u and v are vertices of distance two. The L(2, 1)-labeling number, or the lambda number \(\lambda (G)\), for G is the minimum span over all L(2, 1)-labelings of G. When \(P_{m}\times C_{n}\) is the direct product of a path \(P_m\) and a cycle \(C_n\), Jha et al. (Discret Appl Math 145:317–325, 2005) computed the lambda number of \(P_{m}\times C_{n}\) for \(n\ge 3\) and \(m=4,5\). They also showed that when \(m\ge 6\) and \(n\ge 7\), \(\lambda (P_{m}\times C_{n})=6\) if and only if n is the multiple of 7 and conjectured that it is 7 if otherwise. They also showed that \(\lambda (C_{7i}\times C_{7j})=6\) for some i, j. In this paper, we show that when \(m\ge 6\) and \(n\ge 3\), \(\lambda (P_m\times C_n)=7\) if and only if n is not a multiple of 7. Consequently the conjecture is proved. Here we also provide the conditions on m and n such that \(\lambda (C_m\times C_n)\le 7\).     

Multifaceted Reality of Juvenile Delinquency: An Empirical Analysis of Structural Theories and Literature

The adolescent’s world of delinquent behaviors and risk and protective factors around each behavior is very complicated and articulating certain characteristics or contents of effective programs thus has been intricate. This paper reports the findings of a study examining an original model with the three problems of major juvenile delinquent behaviors: substance abuse, tobacco smoking and violent behavior, by testing their risk/protective factors derived from theories and past empirical studies. The satisfactory model fit was confirmed with the Structural Equation Modeling and structure of a multidimensional construct in the hypothesized model, which showed specified causal linkage, was validated. The authors also found 10 mediating effects among risk/protective factors either with theoretical/past literature result rationale or authors assumptions which led both to confirmatory and new findings.
