论村民自治组织运作中的权力冲突与对策 总被引：6，自引：0，他引：6
冯毓奎 《上海师范大学学报(哲学社会科学版)》2002,31(6):8-14
村民自治组织作为人民公社制度解体后的替代组织出现,立即成为现阶段中国农村治理的重要方式。但是村民自治组织在实际运作过程中,乡镇政府的管理是基层党支部的直接领导机制依然在发挥重要作用,甚至在有些方面居于主导地位,从而引起村民委员会组织运作过程中难于避免的权力冲突,建立在农村党支部领导方式和职能转换基础上的“两委合一“是一种较为理想的制度选择。 相似文献

The literacy practices of many communities today show new ways of meaning making in the contemporary, technological and digital culture. A number of Malaysian adolescents belong to this culture. This pilot study reports the preliminary findings of a larger study aimed at describing the online activities of Malaysian adolescents. Fifty‐four participants from an urban secondary school in Penang took part in this study. One finding showed that the percentages of language use on the Internet were: 80.6 per cent in English, 10.6 per cent in Bahasa Malaysia and 8.8 per cent in Chinese. In addition, the study also revealed some common websites that these adolescents frequented. The findings point to the need to investigate the extent of these online literacy practices beyond school among the adolescent population in Malaysia and to look into the implications for ESL education. 相似文献

During the 1990s, there was considerable emphasis on promoting particular kinds of pupil grouping as a means of raising educational standards. This survey of 2000 primary schools explored the extent to which schools had changed their grouping practices in response to this, the nature of the changes made and the reasons for those changes. Forty‐eight per cent of responding schools reported that they had made no change. Twenty‐two per cent reported changes because of the literacy hour, two per cent because of the numeracy hour, seven per cent because of a combination of these and twenty‐one per cent for other reasons. Important influences on decisions about the types of grouping adopted were related to pupil learning and differentiation, teaching, the implementation of the National Literacy Strategy, practical issues and school self‐evaluation. 相似文献

Considering the importance of digital skills in university education, this article reports on a study which examined access to technology among first year students at a rural South African university. The study focused on the digital readiness of students prior to their admission to the university, since many universities provide access to computers and the internet. The survey of 156 first year students revealed that 73 per cent of the students had no access to computers at their high schools and 82 per cent of students from rural high schools had no computer access and internet at their schools. Most students from rural areas used a computer for the first time when they were 19 years and older. Many students gained access to computers and the internet for the first time at the university. As a result, they enter the university digitally disadvantaged. Solutions that involve initiatives to provide access to technology are required in addition to digital literacy for educators at high schools. 相似文献

《Journal of moral education》2012,41(2):231-232
This study examined the hypothesis that religiosity would be differentially related to six types of adolescent prosocial behaviour, and that these relations would be mediated by the prosocial value of kindness. Self‐report data were collected from 142 high school students (63 per cent female; 91 per cent White; M age?=?16.8, S?=?.80). Religiosity was a significant positive predictor of kindness, as well as compliant, anonymous and altruistic prosocial behaviour, but not public, dire and emotional prosocial behaviour. Associations between religiosity and both compliant and altruistic prosocial behaviours were mediated by kindness. Direct and indirect paths were found between religiosity and anonymous prosocial behaviour. Thus, partial support was found for the mediational hypothesis. Discussion focused on the utility of distinguishing among different types of prosocial behaviours and on the role of religion and values in promoting moral education. 相似文献

All cases of suspected or verified child abuse (the battered child syndrome) registered at the Department of Paediatrics in Malmö from 1967 through 1974 were surveyed. During this period 52 patients (54 incidents) were observed, the majority in the years 1970 to 1974. In 5 suspected cases the examination, social history and other circumstances excluded physical abuse. The incidence of child abuse in the city of Malmö for the years 1970 to 1974 was estimated at 35 cases per million inhabitants and year. When compared to the incidence reported in an earlier Swedish investigation (Barnmisshandel 1969) the figures suggest a real increase in the rate of child abuse. In comparison with the estimated incidence in USA and Great Britain the Malmö figures appear low, however. The age of the battered children, the family situation and the social characteristics were essentially in agreement with previous reports. Of the inflicted injuries 37 per cent were regarded as serious or very serious. One child died and in another the injuries resulted in permanent damage. Sixteen children had been repeatedly battered. Up to the end of 1974 10 per cent of the children had been rebattered in spite of what had been thought to be adequate measures to prevent further abuse. Forty-three families (6 were excluded for different reasons) were retrospectively analyzed with regard to the domestic and social situation. It was concluded that in 16 of these families it had not been possible to discern that the child was at risk. The investigation emphasizes the need for psychological assessment of battering parents, and suggests that cases of child abuse should be handled by a team of medical and social experts. 相似文献

This article reports and discusses a study which followed up, through case records, 726 children excluded permanently, indefinitely or for fixed–term periods in 1993/4 in 10 LEAs. The outcomes at secondary level in 1998/9 were found to be moderately poor with the problems intensifying for half the sample. Forty six per cent had further primary school exclusions and 36 per cent received exclusions in their secondary education. Looked–after children and those with special educational needs fared worse and achieved less. Case studies showed the kinds of commitment and support that can work even with very difficult cases. 相似文献

This study examined the records of the North Carolina Central Registry of Child Abuse and Neglect to determine which social, family, and child characteristics were most influential in the decision to place a child in foster care. These records contained all theoretically relevant factors as well as demographic data. Analysis included the computation of odds ratios for foster care for each of 250 variables. A maximum likelihood logistic regression model was constructed to obtain the independent and cumulative contribution of each factor. Some expected variables such as parental stress factors (substance abuse) and types of abuse (burns and scalds) placed a child at a significant risk for placement in foster care (p < 0.01). However, less obvious factors such as referral source (law enforcement agencies) or geographic area also placed children at risk. Overall, the model explained little of the variance of these decisions (R2 = 0.168) and poorly predicted placement (sensitivity 66.3 per cent, specificity 74.6 per cent). Using existing data. we were unable to adequately describe the decision process in selecting foster care. 相似文献
