Mothers’ stress,resilience and early intervention

The aim of the study was to examine factors that predict maternal stress, reported by mothers whose infants were diagnosed as having developmental disabilities at the beginning of participating in an early intervention programme ‘Me and My Mommy’ and after one year. A second goal was to identify and to portray a subgroup of resilient mothers. The sample consisted of 70 mothers from intact families, whose infants were diagnosed mostly with Down’s syndrome. All mothers were receiving early intervention services. The mothers were presented questionnaires—Sense of coherence (SOC); Family adaptability and cohesion evaluation (FACES III); Coping scale of parenting stress index (PSI‐SF), at the beginning and at the end of the year. They were also interviewed at the end of the intervention regarding their satisfaction with the programme. The results showed that at the beginning of the year, the mothers’ sense of coherence had predicted the stress experience. After a year of participation in the intervention, in addition to the contributions of the initial stress and the mothers’ satisfaction with the intervention programme, the following variables: the mothers’ sense of coherence, coping style and family cohesion, assessed at the beginning of the intervention, were considered. A group of resilient mothers was identified and they revealed following intervention a higher sense of coherence, lower stress, an increased family cohesion and decreased family adaptation measures. The results have implications for the planning of effective intervention programmes.     

Preservice teachers’ work stress, self-efficacy, and occupational commitment in four countries

In this study, we examine the teaching-related stress, self-efficacy, and occupational commitment of preservice teachers from two culturally western and two culturally eastern countries. The sample included 1,187 participants from Canada (n?=?379), England (n?=?203), Hong Kong (n?=?211), and Thailand (n?=?394). Self-efficacy partially reduced (mediated) the effect of stress from student behavior and from workload on commitment in three of four contexts. Mediation tests with country as moderator revealed significant differences in the strength of the mediating effect across the four contexts. The results suggest that teachers’ self-efficacy changes the way in which work stress influences the commitment to continue teaching, although cultural milieu influences the nature of the relationship according to context.

Roles of position, stress, and proficiency in L2 children’s spelling: A developmental perspective

This study investigated the roles of phoneme position, stress, and proficiency in L2 spelling development by Taiwanese students learning English as a Foreign Language (EFL), an alphabetic writing system typologically different from the learners’ L1 logographic system. Structured nonword spelling tests were administered to EFL sixth-graders with lower and higher English proficiency level. The results showed that overall, final phonemes were spelled more poorly than their initial and medial counterparts; however, phoneme position effect decreased as learners’ English proficiency improved. Secondly, spelling of the stressed syllable was significantly better than that of the unstressed syllable. However, when phonemes were held constant, stress effect was significant only in the first, but not in the second syllable. Thirdly, higher proficient EFL children spelled significantly better than their lower proficient counterparts, and spelling errors were more systematic in the former. The findings of the study are discussed from linguistic, psychological, and developmental perspectives.     

Parents’ perception of child behavior,parenting stress,and child abuse potential: Individual and partner influences

Based on the Social Information Processing model of parenting risk for child abuse, the present study examined the associations between mothers’ and fathers’ perception of child behavior and child abuse potential, as well as whether parenting stress mediates the association between these constructs. Two hundred and fifty-nine mother-father couples raising preschool children answered the Child Behavior Checklist (CBCL), the Parenting Stress Index (PSI), and the Child Abuse Potential Inventory (CAPI). The results of dyadic path analysis showed that perception of child behavior was related to heightened parenting stress and abuse potential in both mothers and fathers. Concerning partner effects, we found that mothers’ perception of child behavior problems was positively associated with fathers’ parenting stress and that the higher the mothers’ distress, the higher the fathers’ risk of physical abuse. Finally, parenting distress partially mediated the association between parents’ perception of child behavior and child abuse potential, with mothers’ perception of their children as problematic showing a significant indirect effect through distress on their own abuse risk and on fathers’ CAP as well. These findings suggest that parental distress may represent a critical mechanism by which parents’ negative views of their children contribute to abuse potential. Moreover, mothers seem to influence fathers’ tendency towards abusive behaviors.     

Computer‐mediated support groups: An examination of relationships among social support,perceived stress,and coping strategies

This study examined social support, perceived stress, and coping strategies among participants (N = 148) within twenty‐four computer‐mediated support groups. The results indicated that the amount of time a person reported spending communicating with others in on‐line support groups was positively related to the size of his or her support group network and satisfaction with the support he or she received in online support groups. Satisfaction with both on‐line supportive relationships and face‐to‐face supportive relationships was correlated with degree of reduction in perceived life stress. Satisfaction with on‐line social support was predictive of the types of coping strategies used by participants.     

The best years of our lives? Coping with stress predicts school grades,life satisfaction,and feelings about high school

This study examines whether problem-focused, emotion-focused, and avoidant coping strategies predict key outcomes in a sample of 354 high school students. The four outcomes considered are: academic achievement, life satisfaction, positive feelings towards school, and negative feelings towards school. Results demonstrate that coping incrementally predicts all four outcomes above and beyond the effects of the Big Five personality factors, vocabulary, and demographic variables. Incremental prediction is strongest for school feeling variables, where coping predicts 17.4% of the variance in positive feelings, and 15.9% of the variance in negative feelings. All three coping styles are important in predicting different outcomes: problem-focused coping predicts grades, life satisfaction, and positive feelings about school; emotion-focused coping predicts negative feelings only; and avoidant-focused coping predicts both positive and negative feelings about school. Results suggest that coping styles are an important variable for school outcomes, and that the effectiveness of different strategies differs depending on the outcome considered.     

Simulation study on fluctuant flow stress scale effect

INTRODUCTION With the continuous development of science and technology, especially the rapid progress of electronic industry and micromachine, microparts are needed more and more, and their technical requirements are higher and higher (Geiger et al., 1994; 1996; Geiger and Engel, 2002). However, traditional processing technologies, like cutting, etc., do not meet these requirements. Traditional plastic forming technology has merits like high production rate, excellent me-chanical proper…     

Pedagogical staff in children’s day care centres in Germany – links between working conditions,job satisfaction,commitment and work-related stress

This article investigates links between staff working conditions in children’s day care centres (Kindertageseinrichtungen – known as Kitas in Germany), job satisfaction, commitment and perceived stress at work. Data are based on the nationwide, representative questionnaire survey AQUA (Arbeitsplatz und Qualität in Kitas – Workplace quality in children’s day care centres), a project conducted by the State Institute of Early Childhood Research in Munich. From the participants’ responses (N_total = 6606) regarding their working conditions, an index was established that permitted a categorisation into three groups of quality. Well-established instruments and scales were used to measure general job satisfaction and commitment. The Effort–Reward Imbalance (ERI) model by Siegrist and colleagues (2004) was used to examine stress at work. Results indicate that staff working under good conditions show higher job satisfaction, higher commitment values and less stress at work. Furthermore, distinct differences could be found between centre directors and staff without a leading function.     

The plant response: stress in the daily environment

STRESS IS NORMAL Like animals, plants have evolved to survive in almost every climatic and environmental niche available. They have, however, evolved more so-phisticated and varied methods to enable them to survive environmental changes in light, temperature, atmosphere composition, water and nutrients and salinity. This, in part, is necessary because of the sessile nature of plants; they do not have the ability to move to more favourable environments. Stress conditions that plants enc…     

Teachers’ stress intensifies violent disciplining in Tanzanian secondary schools

Violent forms of discipline in schools continue to be widespread across the globe despite their damaging effects. Since little is known about factors influencing the extent of violence applied by teachers, this study aimed to investigate the influence of teachers’ stress, work satisfaction, and personal characteristics on their disciplining style. Using structural equation modeling, associations between violent discipline, burnout symptoms, and job perceptions (pressure and difficulties in class) reported by 222 teachers from 11 secondary schools in Tanzania in 2015 were analyzed. Results indicated a direct association between perceived stress and emotional violent discipline (β = .18, p < .05) as well as physical violent discipline (β = .37, p < .001). Perceived stress also mediated the association between job perceptions and both forms of violent disciplining. The model showed good model fit (χ² [44, n = 222] = 67.47 (p = .013), CFI = .94, TLI = .91, IFI = .94, RMSEA = .049 [90%-CI = .02–.07, PCLOSE = .50], SRMR = .06). Our findings suggest that teachers’ personal perceptions of their work as well as their stress burden play a role in their disciplining styles. Our findings underline the importance of integrating topics, such as stress and coping as well as positive, nonviolent discipline measures into the regular teacher’s training and in addition to develop and evaluate school-based preventative interventions for teachers.

Constant-step stress accelerated life test of VFD under Weibull distribution case

Constant-step stress accelerated life test of Vacuum Fluorescent Display (VFD) was conducted with increased cathode temperature. Statistical analysis was done by applying Weibull distribution for describing the life, and Least Square Method (LSM) for estimating Weibull parameters. Self-designed special software was used to predict the VFD life. Numerical results showed that the average life of VFD is over 30000 h, that the VFD life follows Weibull distribution, and that the life-stress relationship satisfies linear Arrhenius equation completely. Accurate calculation of the key parameter enabled rapid estimation of VFD life.

Do maternal concerns at delivery predict parenting stress during infancy?

OBJECTIVE: In a previous study, we found that new mothers could and would express concerns about their parenting, including concerns about maltreatment and poor care. In this study, we examine the utility of early maternal concerns for predicting parenting stress in the first year. Parenting stress is important because it has been shown to be related to maltreatment and poor parent-child relationships. METHOD: A sample of 246 mothers were interviewed shortly after delivery in a publicly funded hospital about their parenting concerns, and 93% were reinterviewed in their homes about their parenting when the infants were 6 to 12 months old. Standardized measures with demonstrated psychometric properties were employed, including a measure of parenting stress due to the demands of the parenting role, characteristics of the child that make him or her difficult to care for, and stress due to difficult interactions. RESULTS: Multiple regression results indicate that both mothers concerns at delivery and sociodemographic variables are significant predictors of all three types of parenting stress in infancy. Maternal concerns were more powerful than sociodemographics in predicting stress related to the demands of parenting, while sociodemographics were more powerful for the prediction of stress related to difficult child characteristics and difficult mother-infant interaction. CONCLUSIONS: These findings suggest that knowledge of new mothers' parenting concerns might be useful for predicting parenting problems, as well as for engaging mothers' in and enhancing the effectiveness of parenting services.     

Finite element simulation of stress intensity factors in elastic-plastic crack growth

INTRODUCTION The finite element method (FEM) has been widely employed for solving linear elastic and elas-tic-plastic fracture problems. The evaluation of stress intensity factors in 2D geometries by FEM is a tech-nique widely used for non-standard crack configura-tions. Basically, there are two groups of estimation methods, those based on field extrapolation near the crack tip (Chan et al., 1970; Shih et al., 1976) and those using the energy release when the crack propagates. However…     

Decreasing students’ stress through time management training: an intervention study

The aim of this study was to examine the effects of a time management training program on perceived control of time and perceived stress in the context of higher education. Twenty-three undergraduate students attended a time management training intervention and reported demands, perceived stress and perceived control of time directly before 2 and 4 weeks after training. We used a “non-equivalent dependent variable design” (Cook and Campbell, Quasi-experimentation: design and analysis for field settings, p. 118, 1979) with perceived stress and perceived control of time as dependent variables, which should be influenced by the training, and demands as control variable, which should not be changed. As expected, perceived stress decreased and perceived control of time increased after training, whereas demands did not change. Therefore, time management training might be beneficial for undergraduate students’ well-being. Nevertheless, more intervention studies in this field are necessary, especially with lager samples, to contribute to more robust results and conclusions.     

Optimization design and residual thermal stress analysis of PDC functionally graded materials

INTRODUCTION Polycrystalline diamond compacts (PDC), con-sisting of a polycrystalline diamond (PCD) layer on a WC-Co substrate, and having high hardness and abrasive resistance, are used in a variety of drilling and machining applications (Farhad, 2001; Sadi and Muzaffer, 2001). However, due to differences of thermal and mechanical properties in diamond and WC-Co substrate, residual thermal stresses develop in regions near the interfaces during fabrication. The diamond coating exhib…     

The impact of short-term adventure-based outdoor programs on college students’ stress reduction

This study examines the effect of short-term adventure-based outdoor programs (AOP) on reducing college students’ stress levels. The effects of sex and different outdoor adventure activities in stress reduction are also evaluated. Thirty-three college students participated in selected short-term backpacking, canoeing, and kayaking programs. Student's salivary samples were collected to evaluate physiological stress response (as measured by levels of cortisol) and their psychological stress levels were collected through a modified 12-item questionnaire. Stress responses were measured at three different time points, including the second weekly meeting in the classroom, before the field trip, and at the conclusion of the field trip. Findings suggest that short-term AOP affords opportunities for college students to be away from daily challenges, and in turn reduce college students’ psychological stress levels and provide a temporary relief of physiological stress levels. No significant differences in college students’ stress levels were found between sex and different outdoor adventure activities.
