Cultural Orientation Trajectories and Substance Use: Findings From a Longitudinal Study of Mexican‐Origin Youth 下载免费PDF全文

Cultural adaptation may influence Latino youth substance use (SU) development, yet few longitudinal studies have examined cultural change over time and adolescent SU outcomes. Using longitudinal data collected annually across ages 10–16 from 674 Mexican‐origin youth (50% female), the authors characterized cultural adaptation patterns for language use (English and Spanish use), values (American values and familism values), and identity (ethnic pride), and examined whether these cultural adaptation patterns were associated with differential SU risk. Youth with increasing bilingualism and high/stable family values had lower SU risk compared to youth who primarily spoke English and endorsed decreasing family values, respectively. Ethnic pride trajectories were not associated with SU. Findings highlight the importance of considering cultural change related to Latino youth SU. 相似文献

This paper presents a game designed to support teaching and learning of Portuguese History to 6th grade students. Firstly, a state of the art of mobile game-based learning for History is presented. Then we describe shortly the research carried out which aimed at the analysis of the games most played by students, followed by the identification of the learning principles proposed by Paul Gee and the game mechanics to propose a game structure. Data was collected from students in the 2nd cycle of the Portuguese Educational System (n = 508) through a questionnaire. Finally, we describe the game, that was developed based on those findings, related to a Portuguese historical event - the Republic Implementation in 1910. 相似文献

ABSTRACT Valid and reliable tests of motor competence are necessary to allow researchers and practitioners to quantify levels of motor competence, identify skill deficiencies, and determine the effectiveness of motor skill interventions. The primary study aim was to systematically review the validity and reliability of scores derived from gross motor competence tests for typically developing child and adolescent populations. The secondary aim of this review was to identify the most prevalent motor skills assessed across all instruments. A search of seven electronic databases identified 57 different skill assessment tools from 107 studies. Construct validity was the most common measurement property examined (60 studies; 56%). Content validity (21 studies; 20%) was the least commonly explored measurement property. Scores derived from the Test of Gross Motor Development – second and third edition had the most support for validity and reliability. The most common skills included in these skill batteries were the overhand throw (n = 33), catch (n = 32), jump (n = 31) and hop (n = 26). Research efforts should focus on: (1) further investigation of measurement properties of existing tools rather than developing new assessments and (2) further investigation of existing tools and their measurement properties in adolescent populations. 相似文献

The purpose of this study is to analyse the effect of 12 weeks of non-linear resistance training (NLRT) on anthropometry, muscle strength and inflammatory biomarkers in persons infected with human immunodeficiency virus (PIHIV). Thirty previously sedentary PIHIVs were randomized into the NLRT (n?=?15) and control (CON, n?=?15) groups. NLRT group were submitted to 12 weeks of training, whereas the CON group maintained their daily habits. At baseline and after 12 weeks, both groups underwent anthropometric evaluations and blood sampling for the analysis of inflammatory biomarkers. Analysis of covariance using preintervention values as covariate was performed to determine the effects of exercise on anthropometry, muscle strength, cytokines levels and T cells. Significance was set at p?0.05. After 12 weeks of intervention, there was a decrease in subcutaneous body fat (p?.0001), neck, abdomen and waist circumferences (p .05), waist-to-hip ratio (p?=?.009), blood levels of interleukin (IL)-1β (p?=?.029), IL-6 (p?=?.005), IL-8 (p?=?.010), and tumour necrosis factor (TNF)-α (p?=?.001) and an increase in muscle strength (p?.0001), IL-10 levels (p?=?.030) and CD4+ (p?=?.004) and CD8+ (p?.0001) counts in the NLRT compared to CON group. Twelve weeks of NLRT promoted positive changes in the body fat, body circumferences, muscular strength and inflammatory profile in PIHIV. 相似文献

Previous research has shown that people often engage in cultural-deficit thinking when reasoning about racial/ethnic achievement gaps. However, it is unclear whether culture-blaming explanations are best thought of as group-level internal attributions, expressions of prejudice against a lower status group, or self-serving bias. In this study, White and Latino participants (N = 328) responded to items that were written to express either a White-critical or pro–Asian American perspective on the White–Asian American achievement gap. Results indicated that Latinos were more likely to engage in pro-Asian than White-critical culture blaming, whereas expressions of culture blaming did not vary across frames among White participants. 相似文献

Few studies have evaluated resilience in an academic environment as it relates to academic success or failure. This work sought to assess resilience in regular and remedial students of gross anatomy during the first and second semesters of medical school and to correlate this personal trait with academic performance. Two groups of students were compared: the first group included first‐year medical students in the regular course, and the second group included first‐year medical students who did not pass the regular anatomy course and so were enrolled in the remedial course. Both groups completed anonymous surveys designed to gather demographic data and establish scores on the Connor‐Davidson resilience scale, which includes 25 statements rated zero to four on a Likert scale (maximum score 100). The average resilience score was the same for both groups, 80 ± 9. The average anatomy grades differed significantly between regular students (67± 15.0) and remedial students (61 ± 12.0). While there was no overall correlation between resilience score and anatomy grade, regular students with resilience scores of 75 or greater showed slightly better academic performance than their classmates. Similarly, remedial students with resilience scores of 87 or greater faired better academically. Resilience does not predict academic performance in gross anatomy, and further work is necessary to identify those intrinsic and extrinsic factors that influence students' achievements.

In this paper, the application of Bayesian networks to student modeling is discussed. A review of related work is made, and then the structural model is defined. Two of the most commonly cited reasons for not using Bayesian networks in student modeling are the computational complexity of the algorithms and the difficulty of the knowledge acquisition process . We propose an approach to simplify knowledge acquisition. Our approach applies causal independence to factor the conditional probabilities and decrease the parameters required for each question to a number linear in the number of concepts. This also provides the new parameters with an intuitive meaning that makes their specification easier. Finally, we present an example to illustrate the use of our approach. 相似文献
