HIV/AIDS impacts significantly on pregnant women and on children in Ethiopia. This impact has a multiplier effect on household economies and on productivity losses, and is expected to vary across rural and urban settings. Applying the human capital approach to data collected from 131 respondents, this study estimated productivity losses per HIV-positive pregnant woman–infant pair across urban and rural health facilities in Ethiopia, which in turn were used to estimate the national productivity loss. The study found that the annual productivity loss per woman–infant pair was Ethiopian birr (ETB) 7,433 or United States dollar (US$) 378 and ETB 625 (US$ 32) in urban and rural settings, respectively. The mean patient days lost per year due to inpatient admission at hospitals/health centres was 11 in urban and 22 in rural health facilities. On average, urban home care-givers spent 20 (SD = 21) days annually providing home care services, while their rural counterparts spent 23 days (SD = 26). The productivity loss accounted for 16% and 7% of household income in urban and rural settings, respectively. These high and varying productivity losses require preventive interventions that are appropriate to each setting to ensure the welfare of women and children in Ethiopia.  相似文献

Sleep architecture as well as memory function are strongly age dependent. Slow wave sleep (SWS), in particular, decreases dramatically with increasing age, starting already beyond the age of 30. SWS normally predominates during early nocturnal sleep and is implicated in declarative memory consolidation. However, the consequences of changes in sleep across the life span for sleep-associated memory consolidation have not been evaluated so far. Here, we compared declarative memory consolidation (for word-pair associates) during sleep in young and middle-aged healthy humans. The age groups (18–25 vs. 48–55 yr) did not differ with regard to learning performance before retention periods that covered, respectively, the first and second half of nocturnal sleep. However, after early retention sleep, where the younger subjects showed distinctly more SWS than the middle-aged (62.3 ± 3.7 min vs. 18.4 ± 7.2 min, P < 0.001), retrieval of the word pairs in the middle-aged was clearly worse than in the young (P < 0.001). In contrast, declarative memory retention did not differ between groups after late sleep, where retention was generally worse than after early sleep (P = 0.005). Retention of declarative memories was the same in both age groups when sleep periods containing equal amounts of SWS were compared, i.e., across late sleep in the young and across early sleep in the middle-aged. Our results indicate a decline in sleep-associated declarative memory consolidation that develops already during midlife and is associated with a decrease in early nocturnal SWS.  相似文献

We developed theoretical extensions of Huttenlocher, Hedges, and Duncan's (1991) category-adjustment model of human spatial memory to incorporate the use of fuzzy boundariesand cue-determined prototypes. In two experiments, people reproduced locations of dots in a circle, while the number of external reference cues varied. In Experiment 1, the task field was stable and results were consistent with the use of fixed categories unaffected by number of cues. In Experiment 2, the task field was made dynamic by rotation on most trials, with results evaluated for nonrotation trials. The large cue effects observed for angular bias were consistent with the proposed cue-based fuzzy-boundary model. Large cue effects were also observed for absolute error, consistent with a model in which proximity to cues predicts stability of memory. Results point to the key role of orientation to the task environment in determining whether categorical encoding is based on cues.  相似文献

Studies comparing personality across cultures have found inconsistencies between self‐reports and measures of national character or behaviour, especially on evaluative traits such as Conscientiousness. We demonstrate that self‐perceptions and other‐perceptions of personality vary with cultural mindset, thereby accounting for some of this inconsistency. Three studies used multiple methods to examine perceptions of Conscientiousness and especially its facet Competence that most characterizes performance evaluations. In Study 1, Mainland Chinese reported lower levels of self‐efficacy than did Canadians, with the country effect partially mediated by Canadian participants' higher level of independent self‐construal. In Study 2, language as a cultural prime induced similar effects on Hong Kong bilinguals, who rated themselves as more competent and conscientious when responding in English than in Chinese. Study 3 demonstrated these same effects on ratings of both self‐perceived and observer‐perceived competence and conscientiousness, with participants changing both their competence‐communicating behaviours and self‐evaluations in response to the cultural primes of spoken language and ethnicity of an interviewer. These results converge to show that self‐perceptions and self‐presentations change to fit the social contexts shaped by language and culture.

The focus of this investigation was to determine the possible relationship of workload typologies and other selected demographic variables to levels of burnout among full-time faculty in Seventh-day Adventist colleges and universities in North America. Four typologies of academic workload emerged from the study of the data. The results revealed that there was a significant relationship between academic workload typologies and other selected demographic variables in levels of emotional exhaustion and depersonalization. No relationship was found between the variables studied and levels of personal accomplishment.  相似文献

Based on the responses of 5,557 Chinese secondary students in Hong Kong, the relationships among perceived hopelessness, family functioning, and suicidal ideation were examined. Results showed that suicidal ideation was positively related to hopelessness, but negatively related to parent‐adolescent communication. Compared with father‐adolescent communication, mother‐adolescent communication generally had a stronger association with adolescent suicidal ideation. It was further found that the linkage between hopelessness and adolescent suicidal ideation was stronger under a low parent‐adolescent communication condition, thus suggesting the moderating effect of parent‐adolescent communication on the effect of hopelessness on suicidal ideation. The theoretical and practical implications of the findings are discussed.  相似文献

新西兰对华传教史至今尚被忽略,本文尝试在国际差传体系的大视野下检视新西兰赴华传教的个案,先就人数、差会、性别比例、阶段性发展等因素作通史性勾勒,再以"英属殖民地差传国"、"小型次传教国"和"对华传教对新西兰本土的反向影响"为理论进路挖掘一些易为"外史型"学者所忽略的问题。在海内外中国教会史研究日臻细化的趋势下,新西兰兼具"中心"与"边缘"、"接收"与"差派"的双重属性,加上国土之"小"、人口之"少"、教会史之"短"、宗派之"简"等特点,皆增添了这一课题所潜藏的学术价值。  相似文献

This study examined whether widowhood was associated with physical and mental health, health behaviors, and health outcomes using a cross-sectional (N=72,247) and prospective (N=55,724) design in women aged 50-79 years participating in the Women's Health Initiative observational study (85.4% White). At baseline, married women reported better physical and mental health and generally better health behaviors than widowed women. Whereas women who remained married over the 3-year period showed stability in mental health, recent widows experienced marked impairments and longer term widows showed stability or slight improvements. Both groups of widows reported more unintentional weight loss over the 3-year period. Changes in physical health and health behaviors were inconsistent, with generally small effect sizes. Findings underscore the resilience of older women and their capacity to reestablish connections, but point to the need for services that strengthen social support among women who have difficulty during this transition.  相似文献
