This study reports an investigation into the sources and levels of stress in relation to locus of control and self esteem in university students. Two stress questionnaires (ASQ and LSQ) were used to assess students’ stress. The first deals with academic sources of stress, and the second assesses the student's life stress levels. The achievement scale of the Multidimensional Multi‐attributional Scale Causality (MMCS) was used to measure locus of control, and the Rosenberg Self Esteem Scale to assess students’ self esteem. The study sample consisted of 675 (202 males and 473 females) second‐year undergraduate students. The results indicated that examination and examination results were the highest causes of stress in students, followed by studying for exams, too much to do and the amount to learn, respectively. Results showed that 77.6% and 10.4% of the students fall into the moderate and serious stress categories, respectively, and that there were significant differences between females and males students in both academic and life stress, with female students more stressed than males. Results also indicated a significant positive correlation between locus of control and academic stress, suggesting that students with external beliefs are more stressed than those with internal. A significant negative correlation between self esteem and both academic and life stress emerged, indicating that students with high self esteem are less stressed than are those with low. 相似文献

We report on low-cost fabrication and high-energy density of full-cell lithium-ion battery (LIB) models. Super-hierarchical electrode architectures of Li2SiO3/TiO2@nano-carbon anode (LSO.TO@nano-C) and high-voltage olivine LiMnPO4@nano-carbon cathode (LMPO@nano-C) are designed for half- and full-system LIB-CR2032 coin cell models. On the basis of primary architecture-power-driven LIB geometrics, the structure keys including three-dimensional (3D) modeling superhierarchy, multiscale micro/nano architectures and anisotropic surface heterogeneity affect the buildup design of anode/cathode LIB electrodes. Such hierarchical electrode surface topologies enable continuous in-/out-flow rates and fast transport pathways of Li+-ions during charge/discharge cycles. The stacked layer configurations of pouch LIB-types lead to excellent charge/discharge rate, and energy density of 237.6 Wh kg−1. As the most promising LIB-configurations, the high specific energy density of hierarchical pouch battery systems may improve energy storage for long-driving range of electric vehicles. Indeed, the anisotropic alignments of hierarchical electrode architectures in the large-scale LIBs provide proof of excellent capacity storage and outstanding durability and cyclability. The full-system LIB-CR2032 coin cell models maintain high specific capacity of ∼89.8% within a long-term life period of 2000 cycles, and average Coulombic efficiency of 99.8% at 1C rate for future configuration of LIB manufacturing and commercialization challenges. 相似文献

Research has suggested that academic stress may “spillover” into other life domains and have negative psychological or social
consequences for children and adolescents outside of school settings, but relatively few investigations have examined mediators
and moderators of spillover. The current study explored the mediating role of state affect and the moderating roles of prior
academic performance and mood disturbances on spillover in a sample of 131 French adolescents. Participants completed clinical
measures of anxiety and depression and participated in a 7-day ambulatory monitoring phase that involved multiple daily assessments
of mood, behaviors, and activities. Spillover was observed for family events and subsequent school-related events, as well
as between family and leisure events. These associations remained significant when controlling for immediate mood responses,
suggesting that state affect does not play a salient mediating role. There was no evidence that spillover was moderated by
academic difficulty, anxiety, depression, or gender. Results are discussed in terms of the role that emotional processes may
play in spillover phenomena as well as the reciprocal influence that academic and non-academic events may exert each other. 相似文献

This paper reports an investigation of cognitive style, gender, attitude toward using computer‐assisted learning (CAL) and academic achievement among university students. A Group Embedded Figures Test was used to assess students’ cognitive style and a questionnaire was used for the evaluation of students’ attitude toward CAL. The results revealed that students have positive attitudes toward CAL but they were not prepared to rely entirely on CAL. A 2 x 2 ANOVA was used to investigate the effect of cognitive style and gender on the attitude toward CAL. The results revealed that male students preferred using CAL significantly more than females and field dependent students were more prepared to rely entirely on CAL than field independent students. On the other hand, there was a significant difference between males and females in their achievement scores in favour of the male group. But there was no difference between field dependence and field independence groups in their achievement. The results also revealed no significant relationship between students’ attitudes toward CAL and their achievement in these courses. 相似文献

This study aims to identify sources of stress and consequent stress levels in university academic staff, to identify the coping strategies used by staff, and to examine the relationship between stress levels and job satisfaction. The study sample, consisting of 414 (305 males and 109 females) academic staff, was asked two open‐ended questions which invited them to specify the five main causes of stress in their lives in general and at work. The Life Stress Scale (LSS) was used to assess academics’ stress levels. A coping strategies list was used to identify the strategies used by academic staff during stressful periods. Two questions were asked to assess the level of satisfaction felt by academics with their jobs. The results indicated that academic staff rate work as the most significant cause of stress in their lives (74%) and conducting research (40.3%) was the main cause of stress at work. Results showed also that 74.1% and 10.4% of the academic staff fall into the moderate and serious stress categories respectively, and that there were no significant differences between males and females in stress levels. There were significant differences between the four academic rank groups in stress levels, with lecturers as the most stressed group. The results also indicated that academic staff use a wide range of coping strategies. A negative significant correlation between stress and job satisfaction (r= – 0.444) was found, indicating an inverse relationship between stress level and satisfaction. 相似文献

This study investigated the degree that Science and Engineering Practices (SEPs) criteria from the Next Generation Science Standards (NGSS) were included in self-reported teaching practices of twelfth-grade science teachers in Jordan. This study sampled (n?=?315) science teachers recruited from eight different public school directorates. The sample was surveyed using an instrument adapted from Kawasaki (2015). Results found that Jordanian science teachers incorporate (SEPs) in their classroom teaching at only a moderate level. SEPs applied most frequently included ‘using the diagram, table or graphic through instructions to clarify the subject of a new science,’ and to ‘discuss with the students how to interpret the quantitative data from the experiment or investigation’. The practice with the lowest frequency was ‘teach a lesson on interpreting statistics or quantitative data,’ which was moderately applied. No statistically significant differences at (α?=?0.05) were found among these Jordanian science teachers’ self-estimations of (SEP) application into their own teaching according to the study’s demographic variables (specialisation, educational qualification, teaching experience). However, a statistically significant difference at (α?=?0.05) was found among Jordanian high school science teachers’ practice means based on gender, with female teachers using SEPs at a higher rate than male teachers. 相似文献
