An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness. 相似文献

运动对GLUT4影响的研究进展 总被引:1,自引:0,他引:1
葡萄糖跨膜转运是机体利用葡萄糖的首要步骤。葡萄糖载体(GLUT)是细胞膜上介导葡萄糖跨膜转运的蛋白质,它们对机体的葡萄糖利用有重要意义。运动可有效增加外周组织(主要为骨骼肌和脂肪组织)细胞膜葡萄糖载体4(GLUT4)的数量,使细胞内GLUT4的囊泡数量增多,GLUT4mRNA的表达增强,有效地加快血糖的转移、吸收和利用,解除外周组织胰岛素抵抗,调节血糖平衡,对糖尿病人的治疗有积极的作用和意义。 相似文献

有氧运动对大鼠心血管自主神经调节功能的影响 总被引:2,自引:0,他引:2
首先对心率变异性(HRV)和动脉压力反射敏感性(BRS)的测试分析方法进行了选取和改进,然后以正常大鼠为实验对象,观察比较尾动脉血压、脉搏、左室内压、心肌收缩力、心率变异性、动脉压力反射敏感性等指标在8周中等强度游泳运动组大鼠和和安静对照组大鼠之间的差异,旨在分析长期参加有氧运动对心血管自主神经调节功能的影响,为心血管自主神经平衡状态发生改变提供实验证据。研究发现,与对照组大鼠相比,运动组大鼠心肌出现肥大、心脏泵血功能增强、心交感神经介导的动脉压力反射敏感性升高、心迷走神经介导的动脉压力反射敏感性未受影响、心交感神经紧张性变异和心迷走神经紧张性变异程度均增加。研究结果提示,长期有氧运动可增强心血管自主神经的调节功能,使交感神经和副交感神经的协调与对抗关系在一个更高的功能层面上建立新的平衡。 相似文献

当前,大学生心理问题日益严重。与专业的心理咨询与教育相比,提高全体教育工作者特别是思想政治工作者的职业敏感性发现大学生心理问题更为重要。提高职业敏感性要善于"捕风捉影",长于"小题大做",立足于"长远发展"。 相似文献

Abdominal obesity (AO) has a strong correlation with cardiovascular disease and has been linked to Alzheimer’s disease and type 2 diabetes. We investigated the association between AO and elevated serum butyrylcholinesterase (BChE) activity, insulin resistance and the serum lipid profile, including triglyceride (TG), HDL-cholesterol (HDL-C) and LDL-cholesterol (LDL-C) levels in AO and non-AO women subjects. A total of 500 AO subjects (age 49.1 ± 10.5 years), and 142 non-AO women subjects (age 49.9 ± 11.9 years) were enrolled for the general biochemistry tests, serum BChE, fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR). Body mass index, waist circumference, Blood pressure (BP), plasma glucose (Glu), triglyceride (TG), BChE, insulin, HOMA-IR were significantly higher and HDL-C levels were significantly lower in AO subjects (p < 0.05). Waist circumference was significantly correlated with BP, Glu, TG, BChE, insulin and HOMA-IR in AO subjects. Multiple logistic regression demonstrated that AO was associated with elevated BChE, HOMA-IR, hypertension and reduced HDL-C after adjusting for these variables. AO is associated with elevated BChE, insulin resistance, HT and reduced HDL-C. These may predict the development of type 2 diabetes mellitus and may be associated with cognitive disorder in the future, both are mediated through insulin resistance. 相似文献

Psoriasis is a chronic inflammatory disease associated with an increased insulin resistance, obesity and cardiovascular risk. The present study was aimed to assess insulin resistance and pattern of body fat deposition in psoriasis. Body mass index (BMI) and waist circumference (WC) were measured in 40 psoriatic patients and 46 age- and sex-matched control subjects. Fasting blood glucose (FBG) and serum insulin level were measured by standard photometric method and ELISA respectively. HOMA-IR (homeostatic model of insulin resistance) was calculated by appropriate software. The results indicated that case and control groups were comparable in terms of age and sex (p = 0.934) with an increased prevalence of psoriasis among male subjects (60 %). FBG and mean WC between the two groups were statistically not significant (p value = 0.271 and 0.21 respectively). BMI was significantly higher in case group compared to the control group (p = 0.049). Serum insulin level and insulin resistance in the psoriatic patients were significantly higher (p value <0.001). Multiple regression analysis revealed that insulin resistance (measured by HOMA) was dependent on BMI and WC at a significance level of p < 0.001 and 0.043 respectively. Therefore, the psoriatic patients in this region have significantly high amount of fasting serum insulin level along with an increased IR though their FBG level remains normal. Furthermore, these abnormalities are significantly dependent on total body fat as well as abdominal fat deposits. We suggest that psoriatic patients need to be evaluated for metabolic syndrome and managed accordingly. 相似文献
