Parameter estimation based upon nonparametric function estimators

By considering the solution to a linear approximation of a nonlinear regression problem, a procedure for developing a para¬meter estimator, based upon a nonpammetric estimator of a para¬metric function, is given. The resulting estimators, which are determinable in closed form, are asymptotically normally distri¬buted and are optimal among the class of estimators based upon the function estimator. Further, in many cases, the estimator will have the same asymptotic distribution theory as the correspond¬ing maximum likelihood estimator. Estimators based upon the Kaplan-Meier quantile function are developed for randomly censored samples.     

Corporate eLearning: Human resource development implications for large and small organizations

Abstract

This paper compares and contrasts the current attitudes towards, awareness of and take-up of eLearning in large and small organizations and outlines the implications for human resource development (HRD) professionals. An in-depth study was conducted in Ireland with a number of large multinational organizations and a number of small and medium-sized enterprises (SMEs) in the engineering, electronics, aerospace, pharmaceutical and medical device sectors. The study focused on awareness, perceptions, technology support infrastructure, current and planned involvement, most frequent and most preferred methods of delivery, benefits, barriers, the motivational factors and overall attitudes to eLearning. The comparison describes a number of similarities and a number of differences both within the large organization sector and within the SME sector and between the two sectors. Finally, the implications for HRD professionals are discussed.     

Introduction to the special issue on welfare conditionality in Australia

Conditionality in Australia’s welfare state has sustained a significant academic critique, including the critique published in this journal. In this Special Issue of the Australian Journal of Social Issues, we contribute to the existing critical literature on welfare conditionality. This Special Issue aimed to provide empirical scrutiny into welfare reform and conditionality in Australia. The articles extend our understanding of welfare conditionality’s underpinnings and its lived effects. These case studies illuminate the aspects of welfare conditionality that have not received enough attention: the role of technology, the question of mobility, the relationship with housing and the little thought given to the state’s role in mutual obligation. What is clear is that the individualisation of structural problems is not just a theoretical and political misstep ripe for critique, but leads to the formulation of policies that impact marginalised people’s capacity to shape life on their own terms. Through different empirical foci, all papers in this Special Issue demonstrate how welfare conditionality is put forward as a solution to address the consequences of structural disadvantage.     

Costs of Health Damage from Atmospheric Emissions of Toxic Metals: Part 2—Analysis for Mercury and Lead

In this part of the series we explain the detailed literature review and the calculations of impacts and damage costs of mercury and lead. Methodology and general assumptions are explained in the companion article, Part 1 of this series, and the spreadsheet with the calculations is available as a supplementary file of Part 1.³ For mercury, the damage cost is 22,937 €₂₀₁₃/kg if there is a no‐effect threshold, 52,129 €₂₀₁₃/kg if there is none; 91% is due to mortality from heart disease, the rest from loss of IQ points. For lead, the damage cost is 29,343 €₂₀₁₃/kg, about 80% due to mortality and 20% due to IQ loss; there does not seem to be a no‐effect threshold. These costs are per kg of emitted pollutant.     

Cultural convergence 10 years later: A reexamination of intergroup bias among journalists in the digital media age

This study revisits Filak’s 2004 research of print and broadcast journalists to assess whether changes in the field have diminished the levels of intergroup bias for these groups. The findings here demonstrate that print and broadcast journalists (n = 191) remained biased against each other, even in the face of obvious outside threats and outgroup benefits. In addition, the journalists were more likely to view convergence efforts negatively when these efforts were perceived to be the work of outgroup members. In comparing the data gathered here to that in the original study, dislike and distrust of each other remain consistent. Finally, the influx of digital media, although viewed as valuable by all participants, has had little impact regarding the levels of bias the journalists espoused.     

The impact of CEO turnover on firm performance around interim successions

Prior research reports that financial performance of firms that hire interim CEO successors is worse following interim CEO appointments than those that hire permanent successors. We find that this underperformance occurs only following voluntary turnover interim appointments, which represent a small fraction of all voluntary turnovers and roughly a quarter of all interim appointments. We do not observe poor performance when boards hire interim successors following instances of forced departure. Further analysis shows that poor performance during voluntary turnover interim successions are limited to using operating performance measures; market performance is not significantly worse following interim successions. Our results indicate that many interim appointments should not be viewed as value decreasing endeavors and future research on post-succession financial performance should consider the circumstances surrounding the turnover of the predecessor.     

Women’s Empowerment in the Context of Millennium Development Goal 3: A Case Study of Married Women in Ghana

This paper assesses women’s empowerment in Ghana in the light of the Millennium Development Goal 3. Data for the study were drawn from the 2008 Ghana Demographic Health Survey with an analytic sample of 1,876 married women aged 15–49. Using binary logistic regression in determining the factors that influence women empowerment, this paper examines the relationship between wealth and women’s involvement in household decision-making in the context of healthcare, large household purchases, daily house hold purchases and mobility. The findings show that wealthier married women were significantly more likely to be involved in decision-making on their own healthcare (OR = 2.14, p ≤ 0.001). Also, age, tertiary education and employment significantly shaped the involvement of married women in household decision-making in Ghana. Surprisingly, married women in the Upper East region (the second poorest) were significantly more likely to be involved in three measures of decision-making except for decisions on large household purchases relative to those in the Greater Accra region (the capital). Policies oriented towards an increase in accessibility to tertiary education, employment equity and the creation of income generating activities for women would enhance women’s empowerment in Ghana.     

Correlates of Suicide Ideation Among LGBT Nebraskans

The aim of this investigation is to outline correlates of suicide ideation among LGBT individuals living in Nebraska. A community-based participatory research approach was utilized to develop a 30-minute, online anonymous survey. Almost half of the sample had seriously considered suicide at some point in their lives. Significant correlates of increased likelihood of suicide ideation are age, gender, transgender identity, income, depression, and discrimination. Suicide ideation is a serious concern for the health of LGBT Nebraskans. Steps should be taken to incorporate individuals who fall into these high-risk categories in suicide outreach programs.     

Broken Boundaries or Broken Marriages? Racial Intermarriage and Divorce in the United States

Objective: Several recent studies have investigated the consequences of racial intermarriage for marital stability. None of these studies properly control for first-order racial differences in divorce risk, therefore failing to appropriately identify the effect of intermarriage. Our article builds on an earlier generation of studies to develop a model that appropriately identifies the consequences of crossing racial boundaries in matrimony. Methods: We analyze the 1995 and 2002 National Survey of Family Growth using a parametric event-history model called a sickle model. To appropriately identify the effect of interracial marriage we use the interaction of wife's race and husband's race. Results: We find elevated divorce rates for Latino/white intermarriages but not for black/white intermarriages. Seventy-two percent of endogamous Latino marriages remain intact at 15 years, but only 58 percent of Latino husband/white wife and 64 percent of white husband/Latina wife marriages are still intact. Conclusions: We have identified an important deficiency in previous studies and provide a straightforward resolution. Although higher rates of Latino/white intermarriage may indicate more porous group boundaries, the greater instability of these marriages suggests that these boundaries remain resilient.
