Coverage plots for assessing the variability of estimated contours of a density

Methods for assessing the variability of an estimated contour of a density are discussed. A new method called the coverage plot is proposed. Techniques including sectioning and bootstrap techniques are compared for a particular problem which arises in Monte Carlo simulation approaches to estimating the spatial distribution of risk in the operation of weapons firing ranges. It is found that, for computational reasons, the sectioning procedure outperforms the bootstrap for this problem. The roles of bias and sample size are also seen in the examples shown.     

THE IMPLICATIONS OF CHANGING EDUCATION AND GENDER INPUTS FOR POLICE DECISIONMAKING AND SUPERVISORY ROLES

This article reports the results of a survey of 43 Queensland police officers, half in supervisory roles and half immediately prior to induction. The purpose of the survey was to identify gender and educational differences between groups, and to identify any effect that these differences may have had on attitudes toward decision-making within the sample. The results were compared to a similar survey of American police chiefs. Attitudes toward decision-making were found to be similar among all groups with the exception of the perception of the ability to implement change. This was found to be significantly higher among women and those with a tertiary education. It was also suggested that female officers have the potential to excel in police managerial positions due to higher education levels, but they are currently seriously under-represented in supervisory and managerial positions.     

Career Counseling in the Twenty‐First Century: Beyond Cultural Encapsulation

The author analyzes the context in which professional career counseling in the U.S. exists at the beginning of the 21st century and makes recommendations to enhance the growth and development of the profession. The issues addressed include developing curricula, training career counselors, broadening the focus on career decision making to include work adjustment, improving the basic and advanced skills of career counselors, and extending career services to diverse groups in the U.S. and to people in other nations. Specific strategies that address each of these issues are discussed.     

COMPETITIVE INDUSTRY EQUILIBRIUM UNDER UNCERTAINTY AND FREE ENTRY

This paper investigates the properties of industry equilibrium under price uncertainty given free entry and exit. For any form of risk-averse behavior, it is shown that an increase in demand uncertainty (as measured by a mean-preserving spread) increases mean output price and reduces output of firms in long-run equilibrium.     

Career Interventions for Gay and Lesbian Clients: A Synopsis of Practice Knowledge and Research Needs

This article provides a comprehensive review of the professional literature on career counseling interventions with gay and lesbian clients. It summarizes the practice knowledge gleaned from that literature and makes recommendations on what research needs to be conducted to establish the area of gay and lesbian career development in the published research literature.     

Understanding exponential smoothing via kernel regression

Exponential smoothing is the most common model-free means of forecasting a future realization of a time series. It requires the specification of a smoothing factor which is usually chosen from the data to minimize the average squared residual of previous one-step-ahead forecasts. In this paper we show that exponential smoothing can be put into a nonparametric regression framework and gain some interesting insights into its performance through this interpretation. We also use theoretical developments from the kernel regression field to derive, for the first time, asymptotic properties of exponential smoothing forecasters.     

Review of educational interventions to increase traditional birth attendants’ neonatal resuscitation self-efficacy

Background

Annually, up to 2.7 million neonatal deaths occur worldwide, and 25% of these deaths are caused by birth asphyxia. Infants born in rural areas of low-and-middle-income countries are often delivered by traditional birth attendants and have a greater risk of birth asphyxia-related mortality.
