Greg Conderman  Toni Van Laarhoven  Jesse Johnson  Lisa Liberty 《Support for Learning》2021,36(4):664-677

Students with disabilities typically experience academic, social, and behavioural challenges in school. Some of these students also often experience anxiety and stress associated with school situations and events. Wearable technologies are an emerging innovation in the United States that can support students with disabilities during stressful academic or social situations. This article discusses issues associated with wearables, offers questions to consider when considering a wearable device for a student, and describes several wearable technologies for students with disabilities.  相似文献   

Acculturative stress and cultural identity styles as predictors of psychosocial functioning in Hispanic Americans     

《Int J Intercult Relat》2021

We test acculturative stress, Hybrid (HIS) and Alternating (AIS) Identity Styles, and their interaction effects as predictors of psychosocial functioning over a 12-day period among Hispanic American university students. Participants completed measures of acculturative stress, HIS, AIS, and internalizing (anxiety and depression) and externalizing (social aggression and rule-breaking) symptoms on Day 1; on Day 12 they completed the symptom measures a second time. Structural equation modelling was used to examine the Day 1 effects of acculturative stress, cultural identity styles, and their interactions on Day 12 symptoms controlling for the Day 1 symptoms. We hypothesized that acculturative stress would predict more, and the HIS would predict fewer, symptoms and that the AIS would moderate the relationship between acculturative stress and symptoms over time. Results indicated that: (1) acculturative stress predicted an increase in internalizing symptoms; (2) the HIS predicted a decrease in internalizing and externalizing symptoms; and (3) the AIS attenuated the relationship between acculturative stress and externalizing symptoms. The results are discussed in relation to the distinctive features of internalizing and externalizing symptoms, and recommendations for future research are advanced.  相似文献   

肺动脉高压发病机制及有氧运动干预对其改善的分子机制研究进展     

滑艺杰  王友华 《中国体育科技》2020,(5):71-79

肺动脉高压(pulmonary arterial hypertension,PAH)是一类以肺动脉渐进性闭塞导致肺血管阻力逐渐升高继而诱发右心室衰竭的一种恶性肺血管疾病。PAH病理发生、发展的机制包括炎症反应诱发的内质网应激(endoplasmic reticulum stress,ERS),继而促使血管平滑肌细胞过度增殖和迁移;以及线粒体自噬相关蛋白PINK1和Parkin以及LC3的表达增加,使血管平滑肌呈现抗凋亡表型,并伴随有氧氧化功能损伤,无氧酵解依赖性增加等问题。PAH进一步发展会诱发多种并发症,包括低氧血症、肺纤维化以及右心肥大,可直接引起肺动脉压增加,继而增加心脏压力导致心力衰竭,这是病理发展的主要方向。作为可能治疗PAH的手段之一,有氧运动可从调控ERS、线粒体自噬、改善机体代谢3个方面抑制PAH病理进程。研究综述了近年来关于PAH发生、发展的分子机制的研究进展,进一步论述了有氧运动对PAH改善的分子机制。  相似文献   

Audience management,online turbulence and lurking in social networking services: A transactional process of stress perspective     

《International Journal of Information Management》2021

In social networking services (SNSs), users’ unclear understanding of the large and invisible audience increases the chances of online turbulence, which is a key source of SNS-induced stress. This growing phenomenon has gained increasing attention in academia and industry due to the undesirable consequences for users and SNS platforms. In this study, we draw from the transactional model of stress to examine how audience management strategies impact online turbulence and lead to neglected unintended audience concern and lurking. We also investigate the role of self-monitoring as a stress inhibitor. We test our model with data collected from 301 SNS users. The results show that the four types of audience management strategies have different effects on online turbulence, which significantly impacts neglected unintended audience concern especially when users have high self-monitoring skills. We believe that this work contributes, both from scientific and practical standpoints, to the understanding of the interventions and stressful responses of online turbulence in SNSs.  相似文献   

Psychological responses to reservation-based discrimination: A qualitative study of socially marginalized youth at a premier Indian university     

《International Journal of Educational Development》2020

Given the history of caste politics in India, it is not surprising that the socially marginalized students face discrimination, especially after the introduction of the reservation policy (affirmative action) in educational institutes. Our qualitative study, informed by Meyer’s Minority Stress model, analysed in-depth interviews with 30 undergraduate students, 3 faculty members, and 4 administrative officials at a premier Indian university to examine the psychological wellbeing of the reserved category students. We analysed how the discrimination processes contributed to students’ poor academic performance, low self-esteem, and weak motivation. Student group affiliations and university resources created a supportive environment for the socially marginalized, despite a small risk of stigmatization due to enrolment in a few campus support-programs. Moreover, there existed a palpable frustration among the socially privileged students, resulting in discriminatory attitudes against reserved categories but not “lower” caste. Our findings call for the attention of college administrators, policymakers, and the society at large to ensure that well-intended social justice policies are efficiently implemented, to deliver justice to the underprivileged students of India.  相似文献   

Effect on growth and productivity of lutein from the chlorophyta microalga,strain MCH of Muriellopsis sp., when grown in sea water and outdoor conditions at the Atacama Desert     

《Electronic Journal of Biotechnology》2021

BackgroundMicroalgae are microorganisms that produce various products, for example, pigments, mainly carotenoids. This study aimed to used the strain of Muriellopsis sp. and to evaluate their behavior when grown in freshwater and seawater, along with indoor and outdoor conditions for both cultures. Growth of the strain was evaluated by determining its biomass, lutein productivity with high-performance liquid chromatography (HPLC), and antioxidant activity by using the 2,2-diphenyl-1-picrilhydrazil (DPPH method).ResultsMuriellopsis sp. strain in indoor cultures showed an increased antioxidant activity. In outdoor conditions, both cultures showed increased cells number, concentration of biomass, and lutein productivity. The percentage of lutein obtained from the strain MCH in indoor conditions was 25 times higher than that reported for calendula, reaching 0.75% of lutein in Muriellopsis sp. cultured in seawater, followed by 0.6% in Muriellopsis sp., cultures in freshwater at day 12 of both cultures. These values exceed that of microalgae Scenedesmus almeriensis, which reaches 0.53% lutein.ConclusionsThe results show that the native strain of the Atacama Desert is one of the largest producers of lutein as compared to those reported to date. The study demonstrated the feasibility of producing this carotenoid with well-known properties to prevent some diseases due to its high nutritional value. Muriellopsis sp. cultivation in open-air seawater is a good precedent for developing mass production of this species in an area where freshwater is scarce and costly.How to cite: Cruz-Balladares V, Marticorena P, Riquelme C.

目的观察12周惯性哑铃练习对轻度认知损害(MCI)老年人认知功能、身体活动能力、生活质量和睡眠质量的影响,并探讨认知改善与其他功能改变之间的关系。方法将45名MCI老年人随机分为干预组(n=22)和对照组(n=23)。干预组受试者进行惯性哑铃练习(3次/周,60 min/次,持续12周),对照组不进行运动干预。结果 12周后,干预组受试者阿尔茨海默病评定量表-认知部分(ADAS-Cog)总分/指令得分、蒙特利尔认知评估量表(MoCA)评分、起立行走计时(TUG)和SF-36健康调查问卷(SF-36)心理总得分均显著改善(均P<0.05)。与对照组相比,干预组受试者ADAS-Cog总分/单词回忆得分/注意力得分、简明精神量表(MMSE)评分、TUG和匹兹堡睡眠指数(PSQI)的改善程度均具有显著差异(P<0.05或P=0.05)。偏相关分析结果显示,SF-36心理总得分改变(r=-0.712)、PSQI改变(r=-0.380)与认知改善程度均呈显著负相关。结论 12周惯性哑铃练习可显著提高MCI老年人的认知功能,并对其移动能力、生活质量和睡眠质量具有积极影响,且心理和睡眠改变程度可能影响认知功能的改善效果。  相似文献   

Becoming Fathers: Initial Exploration of a Support Program for New Fathers     

Stephanie R. Rayburn  J. Douglas Coatsworth 《The Journal of perinatal education》2021,30(2):78

Emerging fathers experience a variety of stressors, including identity and role transitions, changes in their relationships, and challenges in developing caregiving skills. Increasing expectations for father involvement in childcare are emphasizing the importance of the father role, but social supports for new fathers remain scarce. Nineteen expectant and new fathers participated in a pilot 5-week group intervention aimed at improving stress coping and involvement attitudes using a combination of mindfulness practices and skill-building for parenting and partner communication. We administered surveys pre- and postintervention to assess efficacy in the areas of stress, depressive symptoms, father involvement attitudes, and mindfulness. Within-participant differences were compared across participants as well as examining individual reliable change. Results indicated initial reductions in stress and depressive symptoms and increases in the mindfulness constructs of nonjudgment and nonreactivity. No significant changes were found in father involvement attitudes. Perinatal intervention specific to fathers holds promise as an underexplored avenue for supporting families across the transition to parenthood.  相似文献

Attention‐Deficit/Hyperactivity Disorder Symptoms,Perceived Stress,and Resilience in College Students     

Stacey L. Hamilton  Amanda Baraldi  Shelia M. Kennison 《Journal of College Counseling》2021,24(1):49-62

This research investigated the relationships among symptoms associated with attention‐deficit/hyperactivity disorder (ADHD), perceived stress, and resilience in college students. In our study of 558 college students (175 men, 383 women), we confirmed the hypothesis that the relationship between ADHD symptoms and perceived stress is mediated by protective factors associated with resilience. The relationships were not significantly moderated by sex. Implications for increasing resilience in college students and lowering perceived stress for college students are discussed.  相似文献
