An Exploratory Study of the Role of Infidelity Typologies in Predicting Attachment Anxiety and Avoidance

Extradyadic involvement (EDI) is one of the greatest challenges that couples and couples therapists face. Many clinicians and researchers attempt to understand motivations for EDI; however, there is a lack of theory-driven research to support claims of infidelity typologies. The current study explored the relationship between adult attachment dimensions of avoidance and anxiety and the attachment-based typology proposed by Woolley (2010). Results indicate significant differences in attachment anxiety in high anxiety affair types versus low anxiety affair types. Results confirmed significant differences in mean attachment anxiety for participants endorsing multiple affairs.     

The Role of Curiosity in the Sociopolitical Development of Black and Latinx Adolescents

Sociopolitical development, the process of coming to understand and take action against systems of oppression, is associated with key outcomes for youth. Although rooted in Paulo Freire's work on critical consciousness, sociopolitical development models overlook a motivational attribute—curiosity—that Freire characterized as a catalyst of such development. This longitudinal study investigated the relationship between curiosity and two aspects of sociopolitical development (social analysis, societal involvement) in a sample of Black and Latinx adolescents (N = 659). Longitudinal growth models demonstrated positive growth in all constructs over 4‐years of high school. Multivariate growth models revealed a positive correlation at baseline between curiosity and both constructs; growth in curiosity was also positively correlated with growth in social analysis and societal involvement.

A Literature Review of Organizational Behavior Management Interventions in Human Service Settings from 1990 to 2016

We reviewed the Journal of Applied Behavior Analysis (JABA), Journal of Organizational Behavior Management (JOBM), and Behavior Analysis in Practice (BAP) from 1990 to 2016, to identify articles that evaluated organizational behavior management interventions in a human service setting. Of those articles, 75 articles met the inclusion criteria for the review, 44 from JABA (1990 to 2016), 22 from JOBM (1990 to 2016), and 7 from BAP (2008 to 2016). We categorized each selected article by setting, employee population, client population, assessment, dependent variable, independent variable, and outcome measures. Results from the review are discussed for all three journals. Recommendations are made to broaden the scope of population and dependent variable targets, include more assessments, and include outcome data when applicable.     

The Role of Media Exposure on Coordination in the Humanitarian Setting

Despite high demand and resource limitations, humanitarian organizations (HOs) typically do not share resources and/or coordinate in the field. While coordination enhances operational performance and saves costs, the general perception is that it dilutes the media attention that individual organizations might receive, and negatively influences their future donation income. In this study, we empirically unveil the impact of media exposure and operational performance on the donations obtained by HOs. Then, based on the empirical results, we develop a stylized model to characterize the structure of preferred coordination policies with respect to an organization's funding source and main mandate. Our findings shed light on the incentives and dynamics that drive behaviors in humanitarian operations and provide insights for policy makers on designing and implementing mechanisms that encourage humanitarian coordination.     

Risk Estimation and Value-of-Information Analysis for Three Proposed Genetic Screening Programs for Chronic Beryllium Disease Prevention

Genetic differences (polymorphisms) among members of a population are thought to influence susceptibility to various environmental exposures. In practice, however, this information is rarely incorporated into quantitative risk assessment and risk management. We describe an analytic framework for predicting the risk reduction and value-of-information (VOI) resulting from specific risk management applications of genetic biomarkers, and we apply the framework to the example of occupational chronic beryllium disease (CBD), an immune-mediated pulmonary granulomatous disease. One described Human Leukocyte Antigen gene variant, HLA-DP beta 1*0201, contains a substitution of glutamate for lysine at position 69 that appears to have high sensitivity (approximately 94%) but low specificity (approximately 70%) with respect to CBD among individuals occupationally exposed to respirable beryllium. The expected postintervention CBD prevalence rates for using the genetic variant (1) as a required job placement screen, (2) as a medical screen for semiannual in place of annual lymphocyte proliferation testing, or (3) as a voluntary job placement screen are 0.08%, 0.8%, and 0.6%, respectively, in a hypothetical cohort with 1% baseline CBD prevalence. VOI analysis is used to examine the reduction in total social cost, calculated as the net value of disease reduction and financial expenditures, expected for proposed CBD intervention programs based on the genetic susceptibility test. For the example cohort, the expected net VOI per beryllium worker for genetically based testing and intervention is $13,000, $1,800, and $5,100, respectively, based on a health valuation of $1.45 million per CBD case avoided. VOI results for alternative CBD evaluations are also presented. Despite large parameter uncertainty, probabilistic analysis predicts generally positive utility for each of the three evaluated programs when avoidance of a CBD case is valued at $1 million or higher. Although the utility of a proposed risk management program may be evaluated solely in terms of risk reduction and financial costs, decisions about genetic testing and program implementation must also consider serious social, legal, and ethical factors.     

Quantitative Methods for Environmental Justice Assessment of Transportation

Application of Executive Order 12898 to risk assessment of highway or rail transport of hazardous materials has proven difficult; in general, the location and conditions affecting the propagation of a plume of hazardous material released in a potential accident are unknown. Therefore, analyses have only been possible in a geographically broad or approximate manner. The advent of geographic information systems and development of software enhancements at Sandia National Laboratories have made kilometer-by-kilometer analysis of populations tallied by U.S. Census blocks along entire routes practicable. Tabulations of total or racially/ethnically distinct populations close to a route, its alternatives, or the broader surrounding area, can then be compared and differences evaluated statistically. This article presents methods of comparing populations and their racial/ethnic compositions using simple tabulations, histograms, and chi-square tests for statistical significance of differences found. Two examples of these methods are presented: comparison of two routes and comparison of a route with its surroundings.     

Organizations in the Public Sector in Hong Kong: Core Government, Quasi-Government and Private Bodies with Public Functions

Twenty-five years ago, the Hong Kong government was lauded as the model of a small, restricted government which was most suited to capitalist economic growth. Since that time, the government and the organizations which it has created have expanded to such an extent that there has been widespread concern that the public sector has grown too large. This article examines the reasons for the rapid growth in the size of the public sector, reflects on the organizational forms outside the traditional civil service that have been adopted, and analyzes the attempts that have been made to reduce the public bureaucracy by corporatizing and privatizing some of the services that it provides. Central to the argument presented is the question of whether an ideological commitment to small government or other functional and political factors have been the critical determinants of organizational change.     

Sample sizes for estimation in clinical research

A sample size justification should be given for all clinical investigations. However, sometimes the objective of a trial is to estimate an effect with a view to planning a later definitive study. This paper describes the calculations for designing studies where one wishes to adopt an estimation approach through using confidence intervals around the overall response. Calculations are given for data anticipated to take a Normal form. Copyright © 2004 John Wiley & Sons, Ltd.
