Identifying the Meaning of Acculturative Stress in Latino Adolescent Girls

poster abstractThere are significantly high depression and suicide attempt rates among Latino adolescents in Indiana. Recently, in a large Community-Based Participatory Research Study (CBPR) meant to identify predictors of depression in Latino adolescents and determine if predictors differ by gender found that Latino adolescent females are more impacted by acculturative stress as a predictor of depression than their male counterparts. Acculturative stress is the stress of navigating two cultures, one at home, one outside the home, and affects immigrants and children of immigrants. The Social, Attitudinal, Familial, and Environmental (SAFE) scale is the research instrument that was used to currently evaluate acculturative stress in the CBPR study. Although psychometrically sound, the scale does not provide details about the experience of acculturative stress, just the presence. As a result, it was concluded that qualitative data in the form of interviews should be gathered from Latino adolescent females in order to complement the quantitative data collected. Interviews with 10-20 Latino females ages 14-17 are being conducted to gain a better understanding of the meaning and influence of acculturative stress in the lives of Latino adolescent females. Once the Latino adolescent interviews have been collected, they will be transcribed and analyzed. Themes will be retrieved from the data and conclusions will be made. The data collected will inform the Latino adolescent camp intervention Your Life. Your Story. (YLYS). With new insight into the meaning attributed to acculturative stress in Latino adolescent females, the curriculum of the YLYS intervention will be adjusted to better serve the needs of its participants and provide a more comprehensive understanding of the topic to the scientific community.

Authenticity, Vulnerability, and Shame in Peer Relationships among Marginalized Youth Living with Mood and Anxiety Disorders

Meaningful peer relationships are developmentally important for adolescents and young adults. Yet trauma histories and stigma around mental illness can impede connection for marginalized youth living with mental health challenges. This study was grounded in relational-cultural theory, which posits that relationships characterized by authenticity and supported vulnerability foster growth; however, in the absence of support for vulnerability, people are likely to relate inauthentically. This qualitative study explored how young people living with mental health challenges navigated issues of authenticity, shame, and vulnerability in peer relationships. As part of a broader feasibility study of an intervention providing services to youth living with mental illness, in-depth interviews were conducted with 11 young women, ages 17–20. Participants were ethnically diverse, primarily low-income, and most had histories of child maltreatment. Interviews focused on participants’ peer relationships, and were audio recorded and transcribed verbatim. Coders analyzed transcripts using thematic analysis and interpreted results using relational-cultural theory. While nearly all participants identified a friend or romantic partner as a significant peer, their experiences within these relationships varied considerably. These are described as a continuum of authenticity, along which participants varied in their experiences of supported vulnerability, feelings of shame, and willingness to represent themselves authentically in these relationships. Some participants who lived with mental health challenges and histories of trauma experienced close, supportive relationships with friends and intimate partners. The ability of marginalized youth to navigate issues of authenticity, vulnerability, shame and stigma in their peer relationships is a worthwhile focus for both practitioners and researchers

Comparative Analyses of Plant Transcription Factor Databases

Transcription factors (TFs) are proteinaceous complex, which bind to the promoter regions in the DNA and affect transcription initiation. Plant TFs control gene expressions and genes control many physiological processes, which in turn trigger cascades of biochemical reactions in plant cells. The databases available for plant TFs are somewhat abundant but all convey different information and in different formats. Some of the publicly available plant TF databases may be narrow, while others are broad in scopes. For example, some of the best TF databases are ones that are very specific with just one plant species, but there are also other databases that contain a total of up to 20 different plant species. In this review plant TF databases ranging from a single species to many will be assessed and described. The comparative analyses of all the databases and their advantages and disadvantages are also discussed

Aspectualidad y semántica argumentativa : estativos puros y estativos delimitados El caso de los predicados de ser/estar y saber/conocer

Desde luego, ser y estar, por una parte, y saber y conocer, por Ia otra, están emparentados. Y, según nuestra perspectiva, lo están desde su descripción semántica argumentativa. Pero, al mismo tiempo, ser y saber comparten ciertas propiedades y estar y conocer comparten otras propiedades. En efecto, ser y saber por un lado y estar y conocer por el otro presentan características que permiten agruparlos en dos subclases diferenciadas: Ia de los estativos puros para los primeros y La de los estativos delimitados para los segundos. Así, con el objetivo de verificar nuestra hipótesis, analizamos el comportamiento diferenciado de unos y otros predicados considerados desde Ia perspectiva de Ia Teoría de los Bloques Semánticos. De acuerdo con esa perspectiva, los dos miembros de cada par se relacionan entre si porque conforman polos transpuestos del mismo bloque semántico, en el que el primer verbo del par es descripto según una definición que no contiene Ia noción de limite y el segundo miembro es descripto según una definición que si contiene una noción de limite. Pero no solo eso. Además, los miembros que Ilamamos estativos puros —los primeros miembros de cada par— admiten La correferencia inclusiva cuando concurren con un predicativo, sustantivan los infinitivos de sus verbos y admiten una lectura incoativa en perfectivo. Por su parte, los estativos delimitados correspondientes —es decir, los segundos miembros de cada par—, son externalizados de los primeros, admiten Ia internalización por medio de la ocurrencia con sintagmas de alto grade, se relacionan con un predicado evidencial y sustantivan los participios de sus verbos.Fil: Ramirez, Silvia Patricia.

Resilient outcomes among youth aging-out of foster care: Findings from the National Youth in Transition Database.

The period of transition from foster care to independent living is frequently associated with poor outcomes. While some studies have conveyed patterns of resilience among transition-age foster youth, additional research is needed to examine its stability over time. The present study used data from the National Youth in Transition Database (NYTD) and the Adoption and Foster Care Analysis and Reporting System (AFCARS) to examine the rates and stability of positive, or “resilient” outcomes among foster youth at ages 19 and 21 (N = 4,631). We included domains such as education, employment, and risky behaviors in our assessment of resilient outcomes. About 40% of youth met the criteria for resilience at ages 19 and 21 (i.e., “sustained resilience” group), an additional 28% met the criteria for resilience at one time point only (i.e., “periodic resilience” group), and 30% did not meet the criteria for resilience at any point (i.e., “sustained non-resilience” group). Several risk, protective, and child welfare factors were associated with manifestations of resilient outcomes during the period of transition to adulthood. Implications for policy, practice, and research are discussed

An automated method to extract three-dimensional position data using an infrared time-of-flight camera

Traditional motion capture systems can be prohibitive in healthcare settings from time, cost, space and user-expertise perspectives. Ideally, movement analysis technologies for healthcare should be low-cost, quick, simple and usable in small spaces. This study demonstrates a simple, low-cost and close-range time-of-flight depth-camera system, for automatic gait analysis. A method to automatically track three-dimensional position and orientation of retro-reflective marker-triads in real-time was developed. A marker-triad was applied to a participant (self-selected walking pace): thigh angle (wrt. global-vertical) was calculated. Trials were concurrently recorded using a motion capture system. Root-mean-square error was 2.5°, 1.3° and 2.2° for depth-camera distances of 0.8 m, 1.1 m and 1.4 m respectively. Results indicate that walking distances of 1.1 m are optimal for the current system. Further development and investigation into potential healthcare applications (e.g., low-cost, close-range gait analysis) is warranted

Who Voted in 2016? Using Fuzzy Forests to Understand Voter Turnout

Objective: What can machine learning tell us about who voted in 2016? There are numerous competing voter turnout theories, and a large number of covariates are required to assess which theory best explains turnout. This article is a proof of concept that machine learning can help overcome this curse of dimensionality and reveal important insights in studies of political phenomena. Methods: We use fuzzy forests, an extension of random forests, to screen variables for a parsimonious but accurate prediction. Fuzzy forests achieve accurate variable importance measures in the face of high‐dimensional and highly correlated data. The data that we use are from the 2016 Cooperative Congressional Election Study. Results: Fuzzy forests chose only a small number of covariates as major correlates of 2016 turnout and still boasted high predictive performance. Conclusion: Our analysis provides three important conclusions about turnout in 2016: registration and voting procedures were important, political issues were important (especially Obamacare, climate change, and fiscal policy), but few demographic variables other than age were strongly associated with turnout. We conclude that fuzzy forests is an important methodology for studying overdetermined questions in social sciences
