Russian Bioscience Publications and Journals in International Bibliometric Databases

This article analyzes shares and rankings of Russian bioscience publications and journals in international bibliometric databases. Studying scholarly output, international collaboration, and the share of Russian papers both in national and international journals enables the authors to highlight the current state of biological science and journals in Russia and outline some pronounced trends. A comparative analysis with the leading countries confirms good representation of Russian bioscience journals among other international serials. Certain problems remain unsolved, however: low impact factors, overrepresentation of national papers, and poor online services. Thus, Russian publishers should correct their editorial policy to improve availability and performance of serials.     

Young,Black, and (Still) in the Red: Parental Wealth,Race, and Student Loan Debt

Taking out student loans to assist with the costs of postsecondary schooling in the US has become the norm in recent decades. The debt burden young adults acquire during the higher education process, however, is increasingly stratified with black young adults holding greater debt burden than whites. Using data from the NLSY 1997 cohort, we examine racial differences in student loan debt acquisition and parental net wealth as a predictor contributing to this growing divide. We have four main results. First, confirming prior research, black young adults have substantially more debt than their white counterparts. Second, we find that this difference is partially explained by differences in wealth, family background, postsecondary educational differences, and family contributions to college. Third, young adults’ net worth explain a portion of the black–white disparity in debt, suggesting that both differences in accumulation of debt and ability to repay debt in young adulthood explain racial disparities in debt. Fourth, the black–white disparity in debt is greatest at the highest levels of parents’ net worth. Our findings show that while social and economic experiences can help explain racial disparities in debt, the situation is more precarious for black youth, who are not protected by their parents’ wealth. This suggests that the increasing costs of higher education and corresponding rise in student loan debt are creating a new form of stratification for recent cohorts of young adults, and that student loan debt may be a new mechanism by which racial economic disparities are inherited across generations.     

Computing first-order sensitivity indices with contribution to the sample mean plot

In this paper, we investigate the use of the contribution to the sample mean plot (CSM plot) as a graphical tool for sensitivity analysis (SA) of computational models. We first provide an exact formula that links, for each uncertain model input X_j, the CSM plot C_j(·) with the first-order variance-based sensitivity index S_j. We then build a new estimate for S_j using polynomial regression of the CSM plot. This estimation procedure allows the computation of S_j from given data, without any SA-specific design of experiment. Numerical results show that this new S_j estimate is efficient for large sample sizes, but that at small sample sizes it does not compare well with other S_j estimation techniques based on given data, such as the effective algorithm for computing global sensitivity indices method or metamodel-based approaches.     

Inference for the Birnbaum–Saunders Lifetime Regression Model with Applications

The Birnbaum–Saunders distribution is a positively skewed distribution that is frequently used for analyzing lifetime data. Regression analysis is widely used in this context when some covariates are involved in the life-test. In this article, we discuss the maximum likelihood estimation of the model parameters and associated inference. We discuss the likelihood-ratio tests for some hypotheses of interest as well as some interval estimation methods. A Monte Carlo simulation study is then carried out to examine the performance of the proposed estimators and the interval estimation methods. Finally, some numerical data analyses are done for illustrating all the inferential methods developed here.     

The Economic Value of a Sustainable Supply Chain

The economic rationale to operate a global supply chain in a sustainable manner is developed. Arguments are made based on marketing, finance, and production theories that by engaging in socially responsible behavior the firm will increase sales, decrease costs, reduce financial risk, and increase profits, which will ultimately increase returns to the firm's shareholders. A model is developed of the mechanism by which modern production methods such as lean production and quality management result in sustainable corporate behavior that, in the long run, translates into higher stock valuations. The production effects cause marketing and financial risk effects that are complementary, and all three channels of influence synergistically result in higher stock values in the model. These effects also provide important benefits to other stakeholders of the firms including employees, customers, the environment, and the community. An important ethical issue in global supply chains is working conditions in foreign plants often leading to allegations of sweatshop labor conditions. This issue is used to illustrate how lean production practices can affectconsumers, employees, and financial risk. Conclusions from the sweatshop labor issue are shown to apply to other sustainability issues as well.     

Environmental issues affecting elder abuse victims in their reception of community based services

This study examined the dominant factors that predict the utilization of services by 129 identified elder abuse victims who reside in the community. Utilizing the Andersen Model, services accepted or rejected were analyzed from individual, family and environmental perspectives. Results indicated that service utilization is related to three "need" factors: (1) Victim has cognitive and ADL impairments, (2) Victim has poor health status (self rated), and (3) The abuser is financially dependent on the victim and is also the primary caregiver of the victim. "Enabling" factor (1) Victim lives alone. "Predisposing" factors (1) Abuser is substance abuser and (2) Abuser is female. A great proportion of the elder abuse victims in this study accepted services from an agency that provided a single entry point into the service system and had highly trained personnel utilizing a case management approach.     

Comments on how child protective services investigators decide to substantiate mothers for failure-to-protect in sexual abuse cases

This commentary discusses the decisions of child protective service (CPS) investigators to substantiate mothers for failure to- protect (FTP) in child sexual abuse cases. Four areas are identified in which the scientific literature remains inadequate to fully inform child maltreatment researchers, CPS practitioners and child welfare policymakers on models and outcomes for FTP substantiation decisions. Attention is called to the need for more information about how differences in statutory definitions, common guidelines, and professional education and training influence FTP substantiation decisions. Current gaps in the knowledge base on FTP and nonoffending caregivers are highlighted. doi:10.1300/J070v15n04_05.     

A Gender-based Examination of Past-year Recreational Gamblers

Background Most adults gamble recreationally yet few studies have systematically investigated for gender-related differences in recreational gamblers.Methods Logistic regression analyses were performed on data from a nationally representative sample of respondents from the 1998 Gambling Impact and Behavior Study. Results Female gamblers versus non-gamblers were more likely to report use of alcohol and drugs. Male gamblers versus non-gamblers were more likely to report alcohol use and abuse/dependence, any substance abuse/dependence, and lifetime incarceration. An analysis of gambling by gender group interaction effects did not identify significant differences in health-related measures. Male as compared with female gamblers reported beginning gambling earlier, experiencing higher past-year maximal losses and wins, and finding favorite and engaging in different types of gambling.Conclusions Despite heavier gambling in male as compared with female recreational gamblers, similar mental health functioning was observed in female and male past-year recreational gamblers. Types of gambling problematic for men and women are reflected in the gambling preferences of recreational gamblers.     

Financial Edgework and the Persistence of Rogue Traders

This work explores financial edgework by professional speculative traders as an explanation for the persistence of rogue trading in financial markets. The article joins in the scholarly application of “edgework,” the social psychological study of voluntary risk, to speculative trading. The discussion focuses on the origins and persistence of that subset of behavior wherein the trader knowingly creates the condition in which he or she endangers the brokerage house that employs them and even, at times, threatens the public's perception of the integrity of the securities industry. Going over the edge between risk taking and unauthorized rogue trading is explained by looking at five inducements to escalate risk taking provided in the securities industry. This examination of financial edgework demonstrates how and, to a lesser degree, why rogue trading is a result of the security industry's pursuit of and desire to capitalize upon yet not publicize an occupational culture stressing a “risk‐and‐win” ethos.     

Emotional intelligence and leadership emergence in small groups

We report the findings from two studies that examine the association between emotional intelligence and leadership emergence in small groups. In both studies, members of groups completed measures of emotional intelligence and other individual differences prior to working on a group project. Their peers rated their leadership emergence at the conclusion of the project. Overall emotional intelligence and a number of its dimensions were associated with leadership emergence over and above cognitive intelligence, personality traits, and gender. These findings were observed when emotional intelligence was measured with an ability test but not when it was measured with a self-report scale. Among the dimensions of emotional intelligence, the ability to understand emotions was most consistently associated with leadership emergence.
