The purposes of the study were to (a) identify student attitudes toward older people according to three measures, (b) determine the relationships among the attitudes as shown by these measures, and (c) identify the relationships between age, gender, frequency of communication with older adults, and life experience with older adults. A total of 125 students completed the study at a university in the United States. The attitude measures used were Kogan's Scale for Attitudes toward Old People, a Facts on Aging Quiz (FAQ), and journal entries about beliefs, affects, and experience regarding older people. Results from the three measures were quantified and analyzed for positive and negative attitudes toward older people. 相似文献

The aim of this study was to develop and validate an assessment tool for research consent competence in older participants. A four-item instrument was developed to assess the capacity of the older adults to consent to research. Data were obtained from 203 nursing home residents from two facilities and 201 community-dwelling older adults in a metropolitan city in South Korea. The results revealed that the four-item instrument for assessing the capacity of older adults to consent to research had good internal consistency, convergent and concurrent validity, an acceptable model fit, and good sensitivity and specificity. The short form can be used for gerontological researchers to encourage their older participants to have the capacity to consent to research in informed consent process. 相似文献

This community-based, health promotion intervention for seniors provided a comprehensive review of the effect of body-mind-spirit (BMS) interventions on health behaviors. The 12-week curriculum offered sessions on exercise, nutrition, sexuality, leisure, stress management, cognitive behavioral therapy, forgiveness, and happiness. Gerontological experts carefully reviewed the adequacy of the program's objectives and instructional methods to meet the needs of older adults in South Korea. Seventy community-dwelling older adults were recruited at two community welfare centers and assigned to experimental (n = 32) and control (n = 38) groups. Extensive evaluations found that participation in the BMS program contributed to better outcomes in both physical and spiritual dimensions of health. 相似文献

This experimental study investigated connections between subject expertise and multitasking ability among college students. One hundred thirty college students participated in the study. Participants were assessed on their subject expertise and reading tasks under three conditions: (a) reading only (silence condition), (b) reading with a video playing in the background (background multitasking condition), and (c) reading and watching video simultaneously (test multitasking condition). The data indicated that the participants performed best in the background condition; the experts scored better than the novices; experts performed better when the reading-comprehension questions were more difficult. Implications for teaching are discussed. 相似文献

This article focuses on the role of adult education in community development initiatives that intentionally aim at more general and equitable power-sharing arrangements at local and regional levels. It argues that community-based learning is a necessary component of community development and the rejuvenation of democracy. In the new millennium, citizens participating in civil society need the vehicle of a city-wide broad-based organisation to act for the attainment of these goals. Adult education in North America was founded on citizen action—often around migrant issues: adequate shelter, jobs, English language acquisition, poverty, and urbanisation. Responses to common needs in the Mechanics Institutes, Citizens' Forums, and the Antigonish Movement are only a few examples of how citizen learning changed lifeworld conditions. In this unsettled and unsettling historical moment, as we move from late modernity or post-modernity to some version of a “new world order”, the potential contributions of critical adult education to the future well-being of a global civil society are becoming increasingly apparent. Identifying and assessing means of resistance to the escalating encroachments of international finance and administrative power into the domains of individual and community autonomy is one practical role for adult education. 相似文献

An artificial intelligence technique of back-propagation neural networks is used to assess the slope failure. On-site slope failure data from the South Cross-Island Highway in southern Taiwan are used to test the performance of the neural network model. The numerical results demonstrate the effectiveness of artificial neural networks in the evaluation of slope failure potential based on five major factors, such as the slope gradient angle, the slope height, the cumulative precipitation, daily rainfall and strength of materials. 相似文献

Chlorella vulgaris (CV) has been reported to have antioxidant and anticancer properties. We evaluated the effect of CV on apoptotic regulator
protein expression in liver cancer-induced rats. Male Wistar rats (200∼250 g) were divided into eight groups: control group
(normal diet), CDE group (choline deficient diet supplemented with ethionine in drinking water to induce hepatocarcinogenesis),
CV groups with three different doses of CV (50, 150, and 300 mg/kg body weight), and CDE groups treated with different doses
of CV (50, 150, and 300 mg/kg body weight). Rats were sacrificed at various weeks and liver tissues were embedded in paraffin
blocks for immunohistochemistry studies. CV, at increasing doses, decreased the expression of anti-apoptotic protein, Bcl-2,
but increased the expression of pro-apoptotic protein, caspase 8, in CDE rats, which was correlated with decreased hepatoctyes
proliferation and increased apoptosis as determined by bromodeoxy-uridine (BrdU) labeling and terminal deoxynucleotidyl transferase
mediated dUTP nick-end labeling (TUNEL) assay, respectively. Our study shows that CV has definite chemopreventive effect by
inducing apoptosis via decreasing the expression of Bcl-2 and increasing the expression of caspase 8 in hepatocarcinogenesis-induced
rats.
