Analysis of the Risk and Protective Factors Among Low-Income, First-Generation College Students
One population of particular concern for college-employed social workers is the low-income, first-generation (LIFG) student population. As the national pressure to increase retention in college has intensified, many students are graduating from universities across the country and starting professional careers. In the college population, some students may be classified as either low-income, first-generation, or both. The two classifications combined define a vulnerable population within colleges and universities – those students who are both low-income and first-generation students. The need to examine LIFG college students’ experiences after admittance, particularly in relation to degree attainment, can help social workers determine what programs are effectively helping this population and what needs have yet to be met for this population. Resiliency theory may be especially useful in understanding LIFG college students’ experiences. This study will also examine LIFG students’ mental health needs. By assessing LIFG students’ mental health, this study will build upon what is already known about the mental health problems among college students, as well as build upon existing resilience research. Risk and protective factors were evaluated between academic and nonacademic variables including: factors related to matriculation and characteristics of the current college experience. Mental health needs were also assessed using the MHI-38 (Veit & Ware, 1983). Results showed LIFG students had high parental press, high valuation of college, high academic integration, and high social integration. LIFG students in the sample also showed low psychological distress, with inversely high psychological well-being and high overall mental health scores. These results have implications for future research, policy, practice, and social work education
Youth Sport Spectating among Parents During the COVID-19 Pandemic
The COVID-19 pandemic caused significant changes to family life and youth sports activities around the globe. In efforts to promote continuity and youth participation in sports, and in lieu of risks for spreading the virus at competitions and games, the youth sport environment adapted to meet emerging health and safety protocols. The cancellation of youth sports and shifts to virtual spectating (i.e., watching children play sports online) were often enacted to protect families, yet little is known about how these changes physically, socially, and psychologically impacted parents and the family system. In response, we conducted a mixed-methods study to explore the lived experiences of parents of youth sport participants during the COVID-19 pandemic. This novel and exploratory research discovered several shifts in the physical environment of youth sport, including challenges with technology and limitations in the number of spectators at youth sporting events. Findings also revealed an array of psychosocial experiences among parents including feelings of grief, frustration, and sadness due to restrictions and sport cancellations, as well as fewer child-parent interactions and a diminished connection to sport in response to virtual spectating. We developed a conceptual model of how shifts in the youth sport environment influenced parent spectators. Our findings have important implications for practice and inform future areas of research regarding youth sports and the family system.

Distance Functions and Attribute Weighting in a K-Nearest Neighbors Classifier
To assess environmental health of a stream, field, or other ecological object, characteristics of that object should be compared to a set of reference objects known to be healthy. Using streams as objects, we propose a k-nearest neighbors algorithm (Bates Prins and Smith, 2006) to find the appropriate set of reference streams to use as a comparison set for any given test stream. Previously, investigations of the k-nearest neighbors algorithm have utilized a variety of distance functions, the best of which has been the Interpolated Value Difference Metric (IVDM), proposed by Wilson and Martinez (1997). We propose two alternatives to the IVDM: Wilson and Martinez\u27s Windowed Value Difference Metric (WVDM) and the Density-Based Value Difference Metric (DBVDM) developed by Wojna (2005). We extend the WVDM and DBVDM to handle continuous response variables and compare these distance measures to the IVDM within the ecological k-nearest neighbors context. Additionally, we compare two existing attribute weighting schemes (Wojna 2005) when applied to the IVDM, WVDM, and DBVDM, and we propose a new attribute weighting method for use with these distance functions as well. In assessing environmental impairment, the WVDM and DBVDM were slight improvements over the IVDM. Attribute weighting also increased the effectiveness of the k-nearest neighbors algorithm in this ecological setting.

Tailoring Supports to Youth in Schools: One Approach to Identifying Needs and Targeting Intervention
Youth experiences intersect along their race, gender, language and socioeconomic status, schools must consider the intersectionality in order to improve outcomes. The current study sought to understand if, and to what extent, different clusters of youth in one large urban high school perceive their psychosocial behaviors as well as social and interpersonal skills. Cross-sectional survey data from 1,164 high school youth were collected using four valid scales: Internalizing Behaviors, Externalizing Behaviors, Peer Relationships, and Social Skills. The analytic strategy was twofold. Cluster analysis was used to form homogeneous clusters of the 1,147 complete responses based on a combination of race/ethnicity, socioeconomic status, English language learner status, and gender. Next, a multivariate analysis of variance (MANCOVA) was used to compare cluster profiles on the aforementioned measures. The cluster analysis revealed a 5-factor solution. Findings of the MANCOVA showed that the clusters differed significantly on the set of psychosocial behaviors, social skills, and peer relationships variables (p\u3c0.05, η2= 0.08), with significant univariate differences (p \u3c 0.05) emerging on all four variables. Results point to cluster analysis as an emerging way to identify needs and tailor supports to youth in schools. Youth with identified needs could receive more specialized Tier II and III interventions aligned with their intersecting cultural and personal experiences, in addition to universal interventions to meet school wide priorities

Long term effect of a medical emergency team on cardiac arrests in a teaching hospital
INTRODUCTION: It is unknown whether the reported short-term reduction in cardiac arrests associated with the introduction of the medical emergency team (MET) system can be sustained. METHOD: We conducted a prospective, controlled before-and-after examination of the effect of a MET system on the long-term incidence of cardiac arrests. We included consecutive patients admitted during three study periods: before the introduction of the MET; during the education phase preceding the implementation of the MET; and a period of four years from the implementation of the MET system. Cardiac arrests were identified from a log book of cardiac arrest calls and cross-referenced with case report forms and the intensive care unit admissions database. We measured the number of hospital admissions and MET reviews during each period, performed multivariate logistic regression analysis to identify predictors of mortality following cardiac arrest and studied the correlation between the rate of MET calls with the rate of cardiac arrests. RESULTS: Before the introduction of the MET system there were 66 cardiac arrests and 16,246 admissions (4.06 cardiac arrests per 1,000 admissions). During the education period, the incidence of cardiac arrests decreased to 2.45 per 1,000 admissions (odds ratio (OR) for cardiac arrest 0.60; 95% confidence interval (CI) 0.43–0.86; p = 0.004). After the implementation of the MET system, the incidence of cardiac arrests further decreased to 1.90 per 1,000 admissions (OR for cardiac arrest 0.47; 95% CI 0.35–0.62; p < 0.0001). There was an inverse correlation between the number of MET calls in each calendar year and the number of cardiac arrests for the same year (r(2 )= 0.84; p = 0.01), with 17 MET calls being associated with one less cardiac arrest. Male gender (OR 2.88; 95% CI 1.34–6.19) and an initial rhythm of either asystole (OR 7.58; 95% CI 3.15–18.25; p < 0.0001) or pulseless electrical activity (OR 4.09; 95% CI 1.59–10.51; p = 0.003) predicted an increased risk of death. CONCLUSION: Introduction of a MET system into a teaching hospital was associated with a sustained and progressive reduction in cardiac arrests over a four year period. Our findings show sustainability and suggest that, for every 17 MET calls, one cardiac arrest might be prevented
A Comparative Examination of How Program Design Components Influence Youth Leadership-Skill Development
A growing interest in how adolescents can prepare for the workforce has contributed to the development of positive youth development (PYD) programs focused on youth leadership. This study explored what mechanisms and design components support leadership skill development among youth participating in 3 different PYD leadership programs. All of these programs involve high school students, have a focus on leadership, and emphasize college and workforce readiness. The aims of the study were to (a) examine what commonalities and differences in program design components contribute to skill development, (b) identify what leadership skills youth develop by participating in PYD leadership programs, and (c) explore what underlying mechanisms youth perceive contribute to their skill development over time. A total of 3 focus groups were conducted, each lasting 90 minutes, with a total of 18 youth (i.e., 6 youth per program). Nvivo, a qualitative software, and thematic analysis were used to distill common and differential themes related to the program design components the participants recognized as integral parts of the programs that contributed to their leadership skill development. Common skills developed across all 3 programs included working in groups, public speaking, and problem solving, yet differences in skills were also reported and linked to differences in program design. Additional findings showed several underlying mechanisms supported leadership skill development among youth participants. Findings can inform the development of effective youth leadership PYD programs, thereby further supporting youth in achieving their goals; avoiding harmful behaviors; and developing the competencies, confidence, and values youth need to successfully transition to adulthood
The p68 and p72 DEAD box RNA helicases interact with HDAC1 and repress transcription in a promoter-specific manner
BACKGROUND: p68 (Ddx5) and p72 (Ddx17) are highly related members of the DEAD box family and are established RNA helicases. They have been implicated in growth regulation and have been shown to be involved in both pre-mRNA and pre-rRNA processing. More recently, however, these proteins have been reported to act as transcriptional co-activators for estrogen-receptor alpha (ERα). Furthermore these proteins were shown to interact with co-activators p300/CBP and the RNA polymerase II holoenzyme. Taken together these reports suggest a role for p68 and p72 in transcriptional activation. RESULTS: In this report we show that p68 and p72 can, in some contexts, act as transcriptional repressors. Targeting of p68 or p72 to constitutive promoters leads to repression of transcription; this repression is promoter-specific. Moreover both p68 and p72 associate with histone deacetylase 1 (HDAC1), a well-established transcriptional repression protein. CONCLUSIONS: It is therefore clear that p68 and p72 are important transcriptional regulators, functioning as co-activators and/or co-repressors depending on the context of the promoter and the transcriptional complex in which they exist
