Creating safe learning environments: Developing and maintaining class cohesion

This paper reports on an Australian study that was conducted in two distinct phases. Phase One examined the belief systems of 28 experienced language teachers, while Phase Two used the theoretical framework generated by the teachers to document the social evolution of eight intensive English language classes containing adult learners from diverse cultural and linguistic backgrounds. Phase One revealed that language teachers place high value on class cohesion, believing that classes that operate as cohesive groups provide safe environments for language learning. Phase Two described a range of individual and collective classroom behaviours and identified a variety of strategies used by teachers in their attempts to develop and maintain class cohesion. The study has implications for pedagogy because it foregrounds the importance of class cohesion and identifies the kinds of classroom behaviours that can enhance the development of cohesiveness in language classes. It also raises the question of the degree to which students do actually feel safe in "safe" learning environments.     

Two permutation tests of equality of variances

The F-ratio test for equality of dispersion in two samples is by no means robust, while non-parametric tests either assume a common median, or are not very powerful. Two new permutation tests are presented, which do not suffer from either of these problems. Algorithms for Monte Carlo calculation of P values and confidence intervals are given, and the performance of the tests are studied and compared using Monte Carlo simulations for a range of distributional types. The methods used to speed up Monte Carlo calculations, e.g. stratification, are of wider applicability.     

Health-Promoting Influences of the Family on Late Adolescent Functioning

This study examined whether potentially modifiable health-promoting family factors during mid-adolescence (age 15) predicted adaptive functioning in late adolescence (age 18) among members of a working-class community cohort. Family factors included feeling valued in the family, cohesion, and social support. Late adolescent outcomes covered developmentally salient areas: academic functioning; mental health; suicidal behavior; and social, psychological, and behavioral functioning. Our findings demonstrate that a positive adolescent family milieu is related to both adaptive outcomes and a reduced likelihood of serious difficulties, including mental and behavior problems. Although each hypothesized health-promoting factor was significantly associated with multiple areas of age 18 functioning, the patterns of association differed by type of family factor. Taken together, results suggest that the family remains an important social context during mid-adolescence and that to be most effective programs designed by practitioners aimed at strengthening families should target multiple features of the family environment.     

Perceived Stigma and Depression among Black Adolescents in Outpatient Treatment

Despite the high prevalence of depression among children and adolescents, most that need mental health treatment do not seek care. This is especially true for ethnic minority adolescents. Prior research has shown that perceived stigma may act as a barrier to the initiation of and adherence to depression treatment, yet few studies have examined the relationship between stigma and depression among Black adolescents. This exploratory study examined the relationship between Black adolescents' depression severity and their current level of perceived stigma in an outpatient sample. Face-to-face interviews were conducted with a clinical sample of adolescents referred for mental health services at a community-based outpatient clinic (n =108), participating in a prospective pilot study on adolescents' patterns of mental health service use. The analyses revealed that greater depression severity was significantly associated with higher perceived stigma (p < .05), particularly among females. The results also suggest that Black adolescents appear to exhibit an appropriate level of self-assessment regarding their need for mental health services. These results are interpreted in relation to previous literature, and limitations and directions for future research are discussed.     

Correlates of African American female adolescent offenders 3, 4-Methylenedioxymethamphetamine (MDMA or “Ecstasy”) use and sexually transmitted infection morbidity

Abstract

The current study was designed to determine the extent to which self-reported ecstasy use in a population of juvenile adolescent detainees in a southern state is associated with high-risk health behaviors pertaining to sexually transmitted infection (STI) symptomology and past history of STI occurrence. Participants were 764 African American females extracted from an overall sample of 2,260 juvenile offenders housed at selected Youth Development Campuses in the state of Georgia. Significance tests were conducted using univariate logistic regressions to examine the independent associations of participant’s self-reported ecstasy use and dichotomized HIV risk behavior correlates and history of having a prior STI before the most recent incarceration Participants who reported ecstasy use prior to incarceration were 1.7 (OR = 1.68, 95% CI = 0.78–3.64) and 1.8 times (OR = 1.87, 95% CI = 1.24–2.81) more likely respectively to indicate having had genital warts or chlamydia, and were more than 1.5 times (OR = 2.21, 95% CI = 0.83–5.44) and two times more likely to report having had gonorrhea or herpes, accordingly. Prevention programs for adolescent offender populations should develop interventions that target adolescents’ substance use behavior as a function of STI risk taking as well as being culturally competent to deal specifically with these problem behaviors.     

大家都是过来人

最近跟朋友聊天,大家最关心的话题就是找工作了,因为都是初入职场,所以大家都渴望互相多交流一些情况。一般问起“工作、薪水”来,大家都挺愿意说的,不过至于说的内容里有没有水分我无法判断。我个人也只是问问,心里有个底,别人工作的好坏、薪水高低我是不会作评价的。因为我不看重这个,我想要的是经验,钱少点、工作累点都没
