Bias, racism and evidence-based practice: The case for more focused development of the child welfare evidence base

In spite of continuing concerns about disproportionate representation of African Americans, American Indians, and selected other groups in foster care, development of the practice and policy evidence base has paid scant attention to incorporating the specific concerns of these communities in intervention research. The authors review the current foundation of evidence-based practice and identify gaps in the knowledge base with specific reference to race/ethnicity/culture and class. They recognize the current concerns regarding disproportionality in child welfare services; and summarize the current research on bias and racism to establish potential mechanisms contributing to racially disproportionate outcomes. Addressing these literatures in concert with one another gives new meaning to the phrase, culturally competent evidence-based practice. Culturally competent practice goes beyond admonishing practitioners and policy makers to be more sensitive or to undertake such training. It is a pathway to the development of a more targeted and relevant evidence base: 1) rigorous intervention research with diverse populations could be more intentionally developed and 2) existing rigorous research on successfully addressing bias could be more broadly applied and tested in child welfare. A model for evaluating the validity of the evidence base with respect to diverse populations is proposed.     

Chafee Educational and Training Voucher Programs: System Coordination in Rural New England

This paper explores service providers’ perspectives on a series of issues associated with systemic coordination in the implementation of the Chafee Educational and Training Voucher (ETV) Program in three relatively rural states. Findings derived from mail surveys (N = 105) and in-depth interviews (N = 17) with child welfare and educational service providers highlight challenges and innovations related to working with Chafee ETV eligible youth. Findings suggest that raising awareness of the Chafee ETV program’s provisions, improving access to concrete services, and facilitating collaboration among service providers may aid the transition to post secondary education for youth in out-of-home care.     

Comparison of five approaches to keeping power line maintainers' hands warm during work in the cold

Electric utility workers in Canada must frequently work in the cold and must wear thick rubber gloves which can result in rapid fatigue and reduced performance. The purpose of the study was therefore to document the challenge of working in the cold wearing the standard five-finger rubber gloves and covers and compare them to two equipment options, mitten style gloves or a prototype wool liner, and two heating options, glove or torso heating. The dependent measures were grip force, temperature, dexterity (modified Purdue pegboard test and a simulated occupational task), finger sensitivity (Von Frey hair test), perceived effort and thermal sensation. The study population consisted of 10 experienced male utility workers. They worked in a controlled temperature walk-in chamber (-20 degrees Celsius) and performed simulated utility work for 45 minutes with interspersed test batteries. The mitten style glove and woolen liner in a standard glove reduced the effects of working in the cold compared to the standard five-fingered variety with a thin cotton liner. We found that the mitten style glove showed lesser drops in skin temperature for the 3rd and 5th digits than the other conditions (p < 0.05).     

Does Family Structure Really Influence Educational Attainment?

This paper examines the effects of family structure on educational attainment after controlling for common family influences, observed and unobserved, using data from siblings. The use of sibling data permits us to examine whether the apparent effects of family structure are due to unmeasured characteristics of families that are common to siblings. The data come from pairs of siblings in the National Longitudinal Survey of Youth, 1979–1992. The results suggest that taking into account the unmeasured family characteristics yields estimates of the effects of family structure on educational attainment that are smaller, but still statistically significant, than estimates based on analyses that do not take unmeasured family influences into account.     

A national evaluation of Safe Schools/Healthy Students: outcomes and influences

The Safe Schools/Healthy Students (SS/HS) Initiative has awarded over $2 billion in grants to more than 350 school districts in partnership with local mental health, law enforcement, and juvenile justice agencies. To estimate the impact of grantee characteristics, grant operations, and near-term outcomes in reducing violence and substance use, promoting mental health, and enhancing school safety, logged odds ratios (LORs) were calculated contrasting Year 3 with Baseline performance from grantee-provided data on seven outcome measures. After comparing grantee performance across outcomes and outcomes across grantees, the LORs were entered as dependent variables in a series of meta-regressions in which grantee characteristics, grant operations, and near-term outcomes were tested after controlling for pre-grant characteristics. Findings indicate that the SS/HS Initiative significantly improved most outcomes, that within-grantee performance varied greatly by outcome, and that random-effects meta-regression appreciably decreased the variance available for modeling. The approach demonstrates that the SS/HS Initiative is effective and that locally collected performance data can be used to estimate grantee success in improving youth outcomes.     

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.     

Follow the Leader: A Relational Demography, Similarity Attraction, and Social Identity Theory of Leadership Approach of a Team’s Performance

While voluminous research exists on managerial successions and the decline of female head coaches, limited research has evaluated the impact of the coach’s gender on a team’s performance. Therefore, this study focused on gendered coaching successions to determine if the gender of the head coach influenced the team’s performance when controlling extraneous variables (e.g., revenues, expenses, and team statistics). Utilizing the theoretical foundations of relational demography (Tsui et al. in Productivity and interpersonal relations in work teams characterized by diversity, American Psychological Association, Washington, DC, pp 97–130, 1995) , similar-attraction paradigm (Byrne in The attraction paradigm. Academic Press, New York, 1971) and social identity theory of leadership (SITL; Hogg in Pers Social Psychol Rev 5:184–200, 2001), we hypothesized coaching successions to similar demographic leader-member dyad relationships would positively impact team performance. Data from the National Collegiate Athletic Association and Equity in Athletic Data Analysis websites were collected on all Division I women’s basketball head coaching successions from 2003 to 2010. Coaching predecessors and successors were coded by gender, win-loss ratios, and performance statistics. Analysis of variance and repeated measures analysis of covariance were used to analyze the data. Results indicated demographic similarities in leader-member dyadic relationships do not advance team performance.     

Structured expert elicitation about Listeria monocytogenes cross-contamination in the environment of retail deli operations in the United States

Listeria monocytogenes is among the foodborne pathogens with the highest death toll in the United States. Ready‐to‐eat foods contaminated at retail are an important source of infection. Environmental sites in retail deli operations can be contaminated. However, commonly contaminated sites are unlikely to come into direct contact with food and the public health relevance of environmental contamination has remained unclear. To identify environmental sites that may pose a considerable cross‐contamination risk, to elucidate potential transmission pathways, and to identify knowledge gaps, we performed a structured expert elicitation of 41 experts from state regulatory agencies and the food retail industry with practical experience in retail deli operations. Following the “Delphi” method, the elicitation was performed in three consecutive steps: questionnaire, review and discussion of results, second questionnaire. Hands and gloves were identified as important potential contamination sources. However, bacterial transfers to and from hands or gloves represented a major data gap. Experts agreed about transfer probabilities from cutting boards, scales, deli cases, and deli preparation sinks to product, and about transfer probabilities from floor drains, walk‐in cooler floors, and knife racks to food contact surfaces. Comparison of experts' opinions to observational data revealed a tendency among experts with certain demographic characteristics and professional opinions to overestimate prevalence. Experts’ votes clearly clustered into separate groups not defined by place of employment, even though industry experts may have been somewhat overrepresented in one cluster. Overall, our study demonstrates the value and caveats of expert elicitation to identify data gaps and prioritize research efforts.     

Interventions for musculoskeletal disorders in computer-intense office work: A framework for evaluation

Workplace interventions for work-related musculoskeletal disorders (WMSDs) are usually multifaceted. These interventions tend to deal with multiple work organizational and physical risk factors and have components occurring at different organizational levels. The organizations are often changing, with shifting initiatives and priorities. Evaluation of such interventions poses challenges in documentation of implementation, reduction in exposures, and assessment of improved health outcomes. We describe a means-outcomes framework for evaluating field interventions that includes strategies, activities, objectives and metrics for outcomes using quantitative and qualitative methods. We demonstrate application of the framework to our work with a large newspaper, which builds on existing laboratory, aetiological and best practice evidence to improve musculoskeletal health. The newspaper had adopted several organizational strategies aimed at improving financial performance, including restructuring into teams, a major set of moves/renovations and introduction of new software. Concomitant WMSD-related organizational strategies include an ergonomics policy, human resources activities, promotion of team work, changes in environment and equipment specifications and development of information systems. We have found the framework useful for focusing the purpose of data collection and ensuring coverage of important components. At the same time, it provides sufficient flexibility to respond to the changing process of implementation.     

Inverse prediction for heteroscedastic response using mixed models software

Distributions of a response y (height, for example) differ with values of a factor t (such as age). Given a response y_* for a subject of unknown t_*, the objective of inverse prediction is to infer the value of t_* and to provide a defensible confidence set for it. Training data provide values of y observed on subjects at known values of t. Models relating the mean and variance of y to t can be formulated as mixed (fixed and random) models in terms of sets of functions of t, such as polynomial spline functions. A confidence set on t_* can then be had as those hypothetical values of t for which y_* is not detected as an outlier when compared to the model fit to the training data. With nonconstant variance, the p-values for these tests are approximate. This article describes how versatile models for this problem can be formulated in such a way that the computations can be accomplished with widely available software for mixed models, such as SAS PROC MIXED. Coverage probabilities of confidence sets on t_* are illustrated in an example.
