Does HRD have a moral duty to respond to matters of social injustice?

The purpose of this article is to question whether or not social injustice should matter to human resource development (HRD). The goal is to invoke a sense of moral agency and responsiveness within the HRD community for having more candid and open conversations about social injustice and the lived experiences of marginalized individuals. In this article, a social justice paradigm will be suggested as a dedicated platform for studying social justice as a necessary outcome of social injustice. Organizational social justice will be introduced as a progressive workplace norm that envisions an equal balance of social justice outcomes for all members in organizations and places of work.     

A continuous-time Markov model for estimating readmission risk for hospital inpatients

Research concerning hospital readmissions has mostly focused on statistical and machine learning models that attempt to predict this unfortunate outcome for individual patients. These models are useful in certain settings, but their performance in many cases is insufficient for implementation in practice, and the dynamics of how readmission risk changes over time is often ignored. Our objective is to develop a model for aggregated readmission risk over time – using a continuous-time Markov chain – beginning at the point of discharge. We derive point and interval estimators for readmission risk, and find the asymptotic distributions for these probabilities. Finally, we validate our derived estimators using simulation, and apply our methods to estimate readmission risk over time using discharge and readmission data for surgical patients.     

Location of Inventories in an MRP Environment

Previous research on MRP systems has rarely considered at what level in a modular sub-assembly product structure to hold inventories. Based on a simulation study of an MRP environment, we show that the correct decision concerning where to hold inventory depends on the variance in end-item demand, the amount of inventory investment, and concomitantly, the desired level of customer service. In particular, for small investment in inventories and moderate end-item demand variance, it is equally effective to hold inventories at the subassembly level or the end-item level. But when end-item demand variance is high, subassembly level inventories are better. As inventory investment grows, however, it is best to use a diversified approach of holding both subassembly and end-item inventories, irrespective of end-item demand variance. The robustness of these conclusions is validated by simulating a hypothetical firm that also uses safety time to hedge against uncertainties.     

The impact of missing data and how it is handled on the rate of false-positive results in drug development

In drug development, a common choice for the primary analysis is to assess mean changes via analysis of (co)variance with missing data imputed by carrying the last or baseline observations forward (LOCF, BOCF). These approaches assume that data are missing completely at random (MCAR). Multiple imputation (MI) and likelihood-based repeated measures (MMRM) are less restrictive as they assume data are missing at random (MAR). Nevertheless, LOCF and BOCF remain popular, perhaps because it is thought that the bias in these methods lead to protection against falsely concluding that a drug is more effective than the control. We conducted a simulation study that compared the rate of false positive results or regulatory risk error (RRE) from BOCF, LOCF, MI, and MMRM in 32 scenarios that were generated from a 2(5) full factorial arrangement with data missing due to a missing not at random (MNAR) mechanism. Both BOCF and LOCF inflated RRE were compared to MI and MMRM. In 12 of the 32 scenarios, BOCF yielded inflated RRE compared with eight scenarios for LOCF, three scenarios for MI and four scenarios for MMRM. In no situation did BOCF or LOCF provide adequate control of RRE when MI and MMRM did not. Both MI and MMRM are better choices than either BOCF or LOCF for the primary analysis.     

Users as Citizens: Collective Action and the Local Governance of Welfare

Self-organization amongst users of community care services preceded the consumerist developments of the 1980s and early 1990s, but can be considered to have been "legitimized" by top-down objectives relating to "user involvement". Nevertheless, the objectives and value bases of disabled people's organizations and organizations of users (or survivors) of mental health services have not always been consistent with those of consumerism, and user groups have experienced tensions in determining the extent to which they should respond to official agendas. Drawing on theories of new social movements and of citizenship, this paper considers the developing place of user organizations within systems of local governance. It looks at the way in which groups have sought to assert the legitimacy both of experiential knowledge and of their position as citizens in the face of official responses which have constructed them as self-interested pressure groups. It draws on empirical research investigating local groups of disabled people and of mental health service users conducted in the first part of the 1990s. It discusses the significance of shared identity as a basis for collective action alongside more pragmatic motivations to influence the nature of health and social care services. In the context of appeals to "community" and "partnership" which are starting to replace the discourse of markets and contracts as the key metaphor for both policy-making and service delivery, the article considers likely future roles for groups comprising people often excluded from community.     

Marriage and Desistance From Crime: A Consideration of Gene–Environment Correlation

An impressive body of research has examined the effect of marriage on desistance from a criminal career. Although extensive efforts have been made to control for potential confounders, almost no research has considered the role that genetic influences play in the relationship. In this study, the authors revisited the marriage–desistance connection by analyzing sibling data drawn from the National Longitudinal Study of Adolescent Health (Add Health; Ns ranged between 2,224 and 3,745 siblings) and by using a statistical design that controls for confounding genetic influences. The findings revealed that both marriage and desistance were under genetic influence (h² = .56 and .49, respectively). In addition, before controlling for shared genetic influences, marriage was predictive of desistance. After genetic influences were controlled, the marriage effect remained statistically significant but was reduced by 60%. The implications of these findings for life course criminology are considered.     

Implementing the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP): Teaching Assessment Techniques

The Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) is an assessment tool used with individuals diagnosed with autism spectrum disorder and other language delays (Sundberg 2008). The milestones assessment section of the VB-MAPP is used to determine an individual’s current skill level. The results of the milestones assessment can be used to identify instructional goals and objectives. The current study examined the effects of behavioral skills training (BST) on the administration of the milestones assessment by two educational professionals. The BST intervention resulted in immediate increases in performance for both participants.     

Reducing Risk for Youth Violence by Promoting Healthy Development with Pyramid Mentoring: A Proposal for a Culturally Centered Group Mentoring

This article proposes ways to promote healthy psychosocial development among at-risk young African American males with a multigenerational culturally centered group mentoring intervention. The potential for addressing commonalities of risk factors for both internalized and externalized responses to environment stressors is discussed. The authors propose an innovative group intervention that is influenced by social learning theory, the triadic theory of influence, identity, and cognitive development theory. The article also highlights research that suggests benefits of culturally and therapeutically centered group mentoring. The focus of the proposed intervention is on psychosocial assets that are utilized to nurture life skills developed within the framework of a culturally centered multigenerational group mentoring process called pyramid mentoring.     

Social services for sexual minority youth: Preferences for what,where, and how services are delivered

As part of an internet-based study to investigate experiences of sexual minority youth in the U.S., 544 youth, ages 14–19, were surveyed about their need for services, where they preferred to receive these services, and their preferred method of service delivery. The survey was anonymous and youth were recruited from LGBTQ-specific listservs and venues as well as through social networking sites as a way of reaching youth often not represented in LGBTQ surveys. Youth highly endorsed many types of services, settings, and modes of delivery. Some subgroup differences emerged. Transgender youth and those uncertain about their gender identity expressed stronger interest than others in services to address stress, family issues, and self-defense, and in receiving support and guidance from LGBTQ adults. Few differences in service preferences along demographic lines such as race/ethnicity emerged; however, African American youth were more likely than others to prefer services offered in a place of worship. Contrary to predictions, geographic and community variables were not related to service type, delivery format, or location preferences.
