Estimating the extent and degree of Gambling related problems in the Australian population: A national survey

A stratified random doorknock method was used to interview 2744 respondents in four state capitals in Australia. The interview was in 3 parts with the latter two only administered to regular, once per week or more often gamblers (N=290). The measures completed by this group included the South Oaks Gambling Screen and a range of psychological measures. A conservative interpretation of the results was that problem gamblers, defined in terms of a range of personal and interpersonal gambling-related costs, comprised 1.16% (±0.34%) of the Australian population. It was estimated that problem players losses may account for about one quarter of all expenditures on gambling.     

The Impact of Authority Relations and Feedback Delivery Method on Performance

ABSTRACT

The proliferation of technology has been changing feedback delivery methods in organizations. However, the effectiveness of feedback delivery methods can vary depending on social dynamics (e.g., authority relations) in the organization. The current study was designed to examine the impact of authority relations and feedback delivery methods on performance. A total of 120 participants were recruited to work on a simulated cell-phone assembly task and were exposed to one of the four feedback conditions: (a) authority figure with face-to-face feedback, (b) authority figure with e-mail feedback, (c) non-authority figure with face-to-face feedback, and (d) non-authority figure with e-mail feedback. Results showed that while both feedback delivery methods resulted in high performance with the presence of an authority figure, only face-to-face feedback resulted in high performance with a non-authority figure. Practical considerations for effective feedback delivery methods in relation to authority figures are also discussed.     

The Effects of Parenting Stress,Perceived Mastery,and Maternal Depression on Parent–Child Interaction

ABSTRACT

The purpose of this study was to test a model that delineated the interrelationships among parenting stress, perceived mastery (defined as the belief that one's life chances are under one's own control), maternal depression, and parent–child interaction. A secondary data analysis of the Fragile Family and Child Well-Being Study was conducted, using a sample of 2,650 mothers. Results suggest that parenting stress undermines one's sense of perceived mastery which, in turn, resulted in depression. Moreover, the results also indicated that parenting stress directly affected maternal depression and parent–child interaction. There was no support for the hypothesis that parenting stress undermines one's sense of perceived mastery which, in turn, resulted in depression, which affected one's parent–child interaction. Implications of these findings for professionals working with mothers of young children are discussed. Future research should test this model using other forms of parenting behavior.     

Computation of percentage points

In this note, it is proved that in computing percentage points of a distribution, Halley's method yields convergent solutions under most conditions, and we demonstrate the efficiency of the method with some examples.     

Asymptotic normality and mean consistency for the weighted estimator in nonparametric regression models

In this paper, we mainly study the asymptotic properties of weighted estimator for the nonparametric regression model based on linearly negative quadrant dependent (LNQD, for short) errors. We obtain the rate of uniformly asymptotic normality of the weighted estimator which is nearly $O\left(n^{?1∕4}\right)$ when the moment condition is appropriate. The results generalize the corresponding ones of Yang (2003) from NA samples to LNQD samples and improve or extend the corresponding one of Li et al. (2012) for LNQD samples. Moreover, we obtain some results on mean consistency, uniformly mean consistency, and the rate of mean consistency for the weighted estimator. Finally we carry out some simulations to verify the validity of our results.     

Corporate Environmental Behaviors in Voluntary Programs: Does Timing Matter?*

Objective. Why do some firms participate in voluntary programs earlier than others? What conditions dictate whether firms participate in voluntary programs earlier rather than later? Current research on voluntary programs has not considered discrete processes in which corporate actors could have different motives and objectives in different time dimensions, that is, early versus late. Methods. We adopt a diffusion theory to disaggregate corporate voluntary participation behavior in the Environmental Protection Agency (EPA) sponsored Green Lights (GL) voluntary program. We focus on the GL participants during two periods—the early joiners in 1993–1994, and the late joiners in 1995–1996. Results. At the early diffusion stage, firms are more likely driven by the market motive that garners a “green” reputation, an important strategic asset to promote market competitiveness; at the late diffusion stage, firms are more driven by the institutional motive to improve their relationships with regulatory agencies and subsequently relieve regulatory pressures from them. Conclusion. We find that firms have different motives for GL participation at different diffusion stages. We suggest that policymakers who want to induce firms to join voluntary programs should pay more attention to program designs and implementation schemes that accommodate different corporate interests and objectives in different time orders of firms' participations in voluntary programs.
