Analyzing center specific outcomes in hematopoietic cell transplantation

Reporting transplant center-specific survival rates after hematopoietic cell transplantation is required in the United States. We describe a method to report 1-year survival outcomes by center, as well as to quantify center performance relative to the transplant center network average, which can be reliably used with censored data and for small center sizes. Each center's observed 1-year survival outcome is compared to a predicted survival outcome adjusted for patient characteristics using a pseudovalue regression technique. A 95% prediction interval for 1-year survival assuming no center effect is computed for each center by bootstrapping the scaled residuals from the regression model, and the observed 1-year survival is compared to this prediction interval to determine center performance. We illustrate the technique using a recent center specific analysis performed by the Center for International Blood and Marrow Transplant Research, and study the performance of this method using simulation.     

Processes of Religious and Spiritual Influence in Adolescence: A Systematic Review of 30 Years of Research

This is a systematic review of 30 years (1988‐2017) of empirical research on processes of religious/spiritual influence in adolescence. We followed a multi‐step process that resulted in 241 studies organized according to eight research questions and the corresponding methods and analyses typically used to address them. We coded these studies based on the dimensions of religiosity/spirituality and the youth outcomes involved. In some cases (quantitative studies of mediation and moderation, as well as qualitative studies) we also coded a third process variable. Results of the coding process revealed a number of interesting patterns. First, religiosity/spirituality is generally adaptive for adolescents, protecting them from negative outcomes (e.g., risk behaviors and mental illness), and promoting positive youth development and flourishing. Nevertheless, in some contexts, religiosity/spirituality may be at least partially maladaptive. Second, there is some evidence, from experimental and longitudinal studies, that relations between religiosity/spirituality and adaptive outcomes are causal. Third, there are numerous complex and dynamic processes by which religiosity/spirituality relate to youth outcomes. In terms of mediation studies, the most salient mediating processes seem to involve religiosity/spirituality dimensions, peers, values/attitudes, and social control/norms. Fourth, religiosity/spirituality is multidimensional, involving various interwoven facets at the individual and ecological levels. Private or personal aspects of religiosity/spirituality (e.g., religious/spiritual importance) tend to be more salient predictors of outcomes than public aspects of religiosity/spirituality (e.g., religious worship service attendance). The results of this systematic review point to promising directions for future research. First, more research is needed studying a broader range of dimensions of religiosity/spirituality, processes of influence, and outcomes. In terms of religiosity/spirituality, much of the prior work has focused on overall religiosity/spirituality, and religious/spiritual behaviors (e.g., worship service attendance). In terms of outcomes, the emphasis has been on religiosity/spirituality protecting against maladaptive outcomes (e.g., substance use). Second, more research is needed examining the role of culture, and using more rigorous methods (e.g., experience sampling, experimental design, longitudinal design, or mixed methods). This systematic review provides a detailed analysis of what is known regarding processes of religious/spiritual influence in the lives of adolescents, and hopefully better positions researchers to move the field forward.     

Elements of Social Capital and Academic Performance of Undergraduate Students

Lifetime childlessness has increased in Europe. The relationship between childlessness and psychological wellbeing varies by the wellbeing measures employed, life stage and societal context. Health-related predictors of childlessness (health selection) may mediate the relationship between childlessness and wellbeing and/or influence wellbeing directly. This paper examines the relationship between lifetime childlessness, depressive mood and quality of life in early old age using data from the Survey of Health, Ageing and Retirement in Europe (SHARE) (N = 21,295). Region-specific Ordinary Least Squares Analysis is performed to investigate this relationship and the mediating roles of health selection and marital status are explored. No main effect of childlessness is observed in any of the regions net of socio-demographic, economic and health factors. The significant role of health selection in this relationship is only evident in Eastern Europe. The findings of this study support a more in-depth analysis of the role of marital status in mediating the relationship between childlessness and psychological wellbeing. Consistent relationships between marital status and both measures of wellbeing support further analysis of marital selection in this regard.     

Integrative Intensive Retreats for Veteran Couples and Families: A Pilot Study Assessing Change in Relationship Adjustment,Posttraumatic Growth,and Trauma Symptoms

We assessed a brief, systemic retreat‐style intervention that was developed to address concerns about the utilization of services for veterans coping with traumatic stress. A total of 76 dyads (N = 152) were assessed before and after a 4‐day retreat, which included psychoeducation, group and conjoint therapeutic sessions, and recreational relaxation components. Overall, participants reported a reduction in trauma symptoms, but only support persons experienced a significant increase in posttraumatic growth from pretest to posttest. Both veterans and their romantic partners reported an increase in relationship adjustment after the retreat. Opportunities to address the needs of this population by removing barriers to treatment and reducing feelings of isolation, as well as implications for similar treatments are discussed.     

School co-ethnicity and Hispanic parental involvement

Scholars of immigration disagree about the role ethnic communities play in immigrant families’ engagement in educational institutions. While some researchers argue that the concentration of disadvantaged ethnic groups may prevent meaningful engagement with schools, others argue that ethnic communities can possess resources that help immigrant families be involved in their children’s schooling. In this study we use a nationally representative dataset of Hispanic children from the Early Childhood Longitudinal Study, Kindergarten Cohort (ECLS-K) to determine if the relative size of the Hispanic population in the school affects levels of their parents’ involvement in their education, as well as parents’ perceptions of barriers to their involvement. Our results suggest that a large Hispanic presence in a child’s school can help increase immigrant Hispanic parents’ involvement in their children’s schooling, but there are no benefits for US-born Hispanic parents, indicating that ethnic communities help immigrant families acculturate to American institutions.     

The Role of Historical Knowledge in Perception of Race-Based Conspiracies

We test the hypothesis that knowledge of historically documented, anti-black conspiracies affects perceived plausibility of new, anti-black conspiracies. In Experiment 1 (N = 78), African Americans and European Americans read about a current conspiracy aimed at undermining either African American or European American–elected officials. African Americans perceived the anti-black conspiracy as more plausible and the conspiracy informant as more credible than did European Americans. The difference in perception of informant credibility was mediated by recognition of historically documented, anti-black conspiracies. In Experiment 2, we manipulated European Americans’ (N = 105) exposure to information about historically documented, anti-black conspiracies. European Americans who learned about actual, past anti-black conspiracies perceived new anti-black conspiracies as more plausible than did European Americans who learned about race-silent conspiracies or who did not learn about conspiracies. To the extent that European Americans lack awareness of incidents of racism in US history, they are likely to underestimate the possibility that racism impacts contemporary events.     

Communicatively Managing Religious Identity Difference in Parent-Child Relationships: The Role of Accommodative and Nonaccommodative Communication

Guided by Communication Accommodation Theory, we examine the communicative management of religious difference in parent-child relationships. Using survey data from emerging adults (N = 409), we found that religious difference is associated with decreases in relational satisfaction and shared family identity. Further, parents’ religious communication has the potential to promote relational well-being. Accommodative communication (religious-specific supportive communication and respecting divergent values) was associated with increases in relational satisfaction and shared family identity. Two forms of nonaccommodative communication (inappropriate self-disclosure and emphasizing divergent values) were associated with decreases with relational satisfaction and shared family identity; giving unwanted advice was associated with decreases in relational satisfaction but not shared family identity. Giving unwanted advice moderated the relationship between religious difference and relational satisfaction. Differences were also discovered between families with inter- and intrafaith parental dyads. Findings suggest theoretical and methodological contributions to family communication, religious, and intergroup research.     

Bird and butterfly communities associated with two types of urban riparian areas

We examined the distribution of birds and butterflies at two types of urban riparian areas in the metropolitan area of Denver, Colorado, USA. The sites consisted of relatively natural areas containing native woody vegetation, and those that had been highly modified with trees and shrubs removed and planted with lawn grass. Species richness of both butterflies and birds differed significantly between the two types of sites. Species richness, however, was not significantly correlated between birds and butterflies. Bird abundance was similar between site types but consisted of two assemblages. Brewer's blackbirds, common grackles, bank swallows, and mourning doves were abundant at wooded sites while American robins, European starlings, house sparrows, house finches, and mallards were more abundant at lawned riparian sites. Butterfly abundance was less at lawned sites. This contrast in bird and butterfly response to habitats suggests they respond to different habitats in distinct ways. Both taxon groups, however, were important discriminators between habitat types. Overall, butterfly and bird species richness was 44% less at highly modified riparian sites.
