Gulsah Kemer 《Counselor Education & Supervision》2020,59(1):74-92

Beginning and expert supervisors’ cognitions and cognitive structures were compared via concept mapping, a mixed methods design. Both beginning and expert supervisors reported a variety of cognitions representing developmental characteristics in 3 areas: assessment of supervisees, conceptualization and management of supervision, and supervisory relationship.  相似文献   

School exclusion,substance misuse and use of weapons: an interpretative phenomenological analysis of interviews with children     

Sarah Martin-Denham 《Support for Learning》2021,36(4):532-554

The study presents data drawn from semi-structured interviews with five young people permanently excluded from schools in North East England. The research aimed to investigate the risk factors that lead to the children using illegal drugs, to determine the drivers and implications for drug misuse and the carrying of knives into school. The research also hoped to elicit from the young people, the solutions that could have prevented their exclusion from school. The interviews were analysed using interpretative phenomenological analysis to understand how a homogenous sample made sense of their lived experiences. The findings highlight the importance of prompt identification and support for children with learning and subsequent mental health needs as the evidence suggests they lead to perceived negative behaviours by teachers. The research provides further evidence that behaviour sanctions in mainstream schools such as detention and isolation booths do not improve behaviour but make it worse. Original to this research is the finding that children are consuming drugs before school to cope with their inability to access the learning, to aid their concentration and to medicate themselves to reduce the likelihood of being sanctioned by teachers.  相似文献

李东巧  陈芳  韩涛  杨艳萍  王学昭  王燕鹏  Cynthia Liu  Yingzhu Li 《图书情报工作》2020,64(21):120-129

[目的/意义] 通过构建二模复杂网络模型，揭示隐藏在海量文献中的隐性知识。[方法/过程] 通过NetworkX复杂网络工具包，依据任意两个节点的共现关系构建二模复杂网络模型；对网络模型中节点的共现关系进行加权，计算网络的拓扑信息并进行AP聚类，提取节点间的直接关系；采用AUC方法对AA、JC、加权改进的wAA和wJC等4种链路预测算法进行评价，遴选出最合适的预测算法，并对复杂网络的隐性关系进行预测分析。[结果/结论] 以潜在药物靶点挖掘为例进行的实证研究结果表明，wAA链路预测算法为最优的链路预测算法；二模复杂网络模型、指标和方法体系在美国化学文摘社数据库中的药物靶点挖掘中具有一定的有效性。下一步计划在其他数据库中或其他研究领域中进行尝试，以进一步验证该模型的通用性和有效性。  相似文献   

Improving cognitive and physical function through 12-weeks of resistance training in older adults: Randomized controlled trial

ABSTRACT

We performed a randomized, controlled trial to analyse the effects of resistance training (RT) on cognitive and physical function among older adults. Fifty participants (mean age 67 years, ~60% woman) were randomly assigned to an RT program or a control group. Participants allocated to RT performed three sets of 10-15RM in nine exercises, three times per week, for 12-weeks. Control group did not perform any exercise. Variables included cognitive (global and executive function) and physical function (gait, mobility and strength) outcomes. At completion of the intervention, RT was shown to have significantly mitigated the drop in selective attention and conflict resolution performance (Stroop test: -494.6; 95%CI: -883.1; ?106.1) and promoted a significant improvement in working memory (digit span forward: -0.6; 95%CI: ?1.0; ?0.1 and forward minus backward: -0.9; 95% CI: ?1.6; ?0.2) and verbal fluency (animal naming: +1.4, 95%CI 0.3, 2.5). No significant between-group differences were observed for other cognitive outcomes. Regarding physical function, at completion of the intervention, the RT group demonstrated improved fast-pace gait performance (?0.3; 95% CI: ?0.6; ?0.0) and 1-RM (+21.4 kg; 95%CI: 16.6; 26.2). No significant between-group differences were observed for other mobility-related outcomes. In conclusion, RT improves cognitive and physical function of older adults.  相似文献   

Supervisor Cultural Humility Predicts Intentional Nondisclosure by Post-Master's Counselors     

Ryan M. Cook  Connie T. Jones  Laura E. Welfare 《Counselor Education & Supervision》2020,59(2):160-167

The authors examined supervisor cultural humility as a predictor of supervisee intentional nondisclosure. Using multiple regression in a sample of 101 post-master's counselors, the authors found that 20% of supervisees' intentional nondisclosure was explained by their perceptions of their supervisors' level of cultural humility.  相似文献   

白藜芦醇/富勒烯纳米组装体的制备——在胆管支架抗炎涂层中的应用评估     

高建  刘永佳  戚晓亮  徐汪节  乔中东 《实验室研究与探索》2021,(2):58-62

采用白藜芦醇(Res)和富勒烯(C60)结合制备Res/C60纳米组装体并验证其安全性和抗炎性。通过扫描电子显微镜(SEM)、拉曼光谱和X射线衍射研究了纳米组装体形貌、粒径大小及波谱峰值特征。其次,通过紫外分光光度法研究了Res的药物缓释行为。最后,通过MTT法在人脐静脉内皮细胞(HUVECs)层面验证了Res/C60纳米组装体的安全性以及体外的抗炎性。研究发现,Res/C60纳米组装体呈短棒状,横截面平均直径为(379.74±33.47)nm。拉曼光谱和X射线衍射特征峰显示Res/C60纳米组装体被成功制备。Res/C60纳米组装体的聚氨酯(PU)涂层中Res药物在30 d内累积释放量可达60%左右。胆管支架涂层对HUVECs细胞毒性较低,且通过释放Res可显著抑制炎症因子的释放。  相似文献   

临床诊疗应注重合理用药     

郑庆云 《淮北职业技术学院学报》2021,(2)

药物的主要作用是防治疾病、保障健康、延缓生命。临床上为提高疗效,缩短病程,往往采取联合用药,若联合用药不当,不仅给病人造成经济上的浪费,也会对人体造成不良反应,危害健康,带来难以弥补的损失,这种现象在基层医院尤为突出。因此,必须明确合理用药的意义、必要性及应用原则,方可做到科学配伍,趋利避害。  相似文献
