Stress and psychological distress among trainee secondary teachers in England

The relationships between stress and psychological distress were investigated among a cohort of trainee secondary school teachers in England. Specifically, the study examined the structure of a Teacher Stress Scale and its relationship to mental health as measured by the 12‐item General Health Questionnaire. Three factors were identified: behaviour management, workload, and lack of support. Differences were identified between men and women in respect of stressors and psychological distress. Stress attributed to pupils’ disruptive behaviour and stress attributed to perceived occupational stress were found to be significant predictors of psychological distress. The findings are discussed in relation to the degree to which trainees are prepared for the challenges they are likely to experience as teachers.     

Maternal goal factors in adaptive and maladaptive childhood perfectionism

In this project, 72 middle school students responded to a questionnaire tapping three aspects of perfectionism: self‐striving, socially‐prescribed perfectionism, and concern for mistakes. Their mothers completed a questionnaire assessing goal expression along three dimensions defined as direct expectations (e.g., ‘I set high standards for my child’), controlling expectations (e.g., ‘Only outstanding performance is good enough in our family’), and noncontingent encouragement (e.g., ‘Trying hard is more important than being the best’). Path modelling, using SmartPLS, revealed that direct expectations were associated positively with students' self‐striving, but negatively with socially‐prescribed perfectionism. Controlling expectations were associated with socially‐prescribed perfectionism. Hence, adaptive and maladaptive aspects of students' perfectionism appear to be associated with differential patterns of maternal goal expression.     

School climate factors relating to teacher burnout: A mediator model

The present study investigated components of school climate (i.e. parent/community relations, administration, student behavioral values) and assessed their influence on the core burnout dimensions of Emotional Exhaustion, Depersonalization, and feelings of low Personal Accomplishment. The study weighed the relative contributions of demographic factors (i.e. gender, age, years of teaching experience), teacher satisfaction, and teacher-rated school climate that predict resultant levels of teacher stress and burnout from 17 rural schools in southeastern Ohio. Results revealed that different aspects of school climate related to each of the three primary burnout dimensions. Further, the inverse relationship between school climate and burnout was mediated by teacher satisfaction levels for both Emotional Exhaustion and Depersonalization dimensions. Results from the present study may be used in the development of future intervention targets for reducing teacher stress and burnout.

传统的皖江地区农耕文化表现为安土重迁、勤力农亩的特征。近代前后,伴随着对外交流的加强和市场的刺激因素,皖江地区农耕文化开始呈现出明显的重商求利的特征,实现了由安土重迁向出外谋利、由因循守旧向迎合市场的转变。     

独立同分布R-S(t)串并联系统的结构可靠度

通过定义两种类型的指数分布，运用实用分析法的思想，提出四种系统的当量指数方法，获得四种R—S(t)串并联系统的结构可靠度，证明了四系统可靠度都是K=μR/μS的函数，分别得到了在不同的情况时四类系统可靠度的结论，而且近似地获得显示的可靠性设计表达式，最后用事例给予了证实。     

复合维生素添加剂对高温期淮北麻鸡生产性能和免疫功能的影响

目的:研究饲粮中添加不同水平的复合维生素添加剂对淮北麻鸡生产性能和免疫功能的影响及其相关性。方法:选取480只28周龄淮北麻鸡,随机分为4组,每组3个重复,每个重复40只鸡,饲喂在基础日粮分别添加复合维生素添加剂0(Ⅰ组,对照组)、100 mg/kg(Ⅱ组)、500 mg/kg(Ⅲ组)、1000 mg/kg(Ⅳ组),预试期2周,正试期8周。结果:与对照组比较,1)Ⅲ、Ⅳ组产蛋率比显著提高(P0.05),料蛋比显著降低(P0.05),蛋的受精率、孵化率及出雏率显著提高(P0.05);而Ⅱ组产蛋率、料蛋比、蛋孵化率和出雏率的变化不显著(P0.05);2)Ⅲ、Ⅳ组中血清免疫球蛋白A(Ig A)、免疫球蛋白M(Ig M)和补体C4含量显著提高(P0.05);而Ⅱ组中以上指标含量变化不显著(P0.05);3)Ⅲ、Ⅳ组血清超氧化物歧化酶活性和血清谷胱甘肽过氧化物酶活性及总抗氧化能力明显提高(P0.05),而Ⅱ组变化不明显(P0.05)。结论:饲粮中添加500~1000 mg/kg复合维生素添加剂能提高热应激条件下淮北麻鸡的生产性能、抗氧化能力和免疫功能。

Analytical solution for functionally graded anisotropic cantilever beam under thermal and uniformly distributed load

The bending problem of a functionally graded anisotropic cantilever beam subjected to thermal and uniformly dis-tributed load is investigated,with material parameters being arbitrary functions of the thickness coordinate. The heat conduction problem is treated as a 1D problem through the thickness. Based on the elementary formulations for plane stress problem,the stress function is assumed to be in the form of polynomial of the longitudinal coordinate variable,from which the stresses can be derived. The stress function is then determined completely with the compatibility equation and boundary conditions. A practical example is presented to show the application of the method.     

The desire to emulate parental emotional strategies and its relation to emotion dysregulation among emerging adults

Emotion regulation (ER) is an integral aspect of emerging adults’ mental health, yet little is known about interpersonal factors that influence ER in during this period. This investigation examines emerging adults’ desire to emulate parental ER skills in the relation between perceived parental ER and emerging adults’ emotion dysregulation.A sample of 79 emerging adults (M_age = 18.55 years, SD = .32; 88.6% female, 69.6% White) completed measures of perceived parental ER (Affective Style Questionnaire [ASQ]Hofmann and Kashdan 2010), emotion dysregulation (Difficulties in Emotion Regulation Scale [DERS]Gratz and Roemer 2004), and desire to emulate parental ER (Perception of Emotion Regulation Scale [PERS]).A desire to emulate parental ER skills moderated the relationship between perceived parental ER and emerging adults’ emotion dysregulation in general (B = -.10, SE = .048, t = ?2.07, p = .043), and low emotional awareness in particular (B = -.04 SE = .02, t = ?2.47, p = .02).Findings suggest that emerging adults with an increased desire to emulate parents with lower ER skills report greater emotion dysregulation. Implications for clinical practice, along with future directions for the field of ER, are discussed.
