Since the early 1970s the importance of mothers’ socioeconomic characteristics on their children’s educational and occupational
attainment has been acknowledged. However, it is not clear if fathers’ characteristics have a stronger influence because men
usually have stronger attachments to the labour market, or alternatively mothers’ characteristics are more important because
of their greater role in children’s socialization. This study addresses this question by comparing the influence of father’s
and mother’s education and occupation on student performance in literacy and numeracy using data from 30 countries. The impact
of mother’s education is usually greater or comparable to that of father’s education. In contrast, substantially stronger
effects for mother’s occupational status compared to father’s were rare. In most countries the impact of mother’s socioeconomic
characteristics (education plus occupation) on student performance is comparable to that for father’s. Of the four indicators
of socioeconomic background, father’s occupational status and mother’s educational attainment tend to have stronger effects,
although many countries do not conform to this pattern. There are indications that the relative importance of mother’s characteristics
have increased over time.

Differences in levels of academic achievement according to socio‐economic status (SES), and parental education in particular, have been a persistent feature of Australian education systems. Young people with highly educated parents are more likely than their peers with low‐educated parents to attain high levels of achievement at school. Students with low levels of achievement are less likely than their high achieving peers to complete Year 12 and are more likely to experience negative post‐school outcomes. The SES of the neighbourhood, and in particular, the school attended, has also been found to have an effect on levels of both academic achievement and attainment. For this paper, we conduct analyses of National Assessment Program – Literacy and Numeracy test scores for four cohorts of secondary school students attending government schools in the Australian Capital Territory to examine the associations between parental education, school attended and levels of educational achievement. Our findings show that students with university‐educated parents achieve at much higher levels than their peers with low‐educated parents and that attending a school with a higher proportion of students from educationally disadvantaged families has a negative effect on educational achievement. 相似文献

Research highlights lasting cognitive and academic challenges in youth internationally adopted from institutional care. However, there is a lack of research examining internationally adopted students' sense of membership at school and associated academic and psychological outcomes. The current study measured sense of school membership and academic and psychological outcomes in post-institutionalized internationally adopted high school students (n = 29) compared to adolescents internationally adopted from foster care (n = 28) and non-adopted adolescents (n = 32). Post-institutionalized males had a lower sense of school membership than males adopted from foster care or non-adopted males. Group differences in school membership were mediated by academic achievement and psychological well-being. 相似文献

This purpose of the study was to ascertain the level of ethnic identity formation and its perceived role on school engagement for Tibetan adolescents enrolled in public schools in two Midwestern states in the USA. The journey of these students from culturally encapsulated schools from Nepal, Bhutan, and India to multiculturally diverse settings was one of the most fascinating facets of the Tibetan Diaspora. Subjects included 16 girls, 25 boys, and 2 who did not identify their gender. The multigroup ethnic identity measure was used to determine the level of ethnic identity formation of Tibetan students while a questionnaire gathered information on school engagement. The overall ethnic identity measure for this sample was high with a mean of 3.58, while the cognitive and affective aspect of the measure was also high with a mean of 3.56 and 3.74, respectively. The girls showed more emotional commitment to ethnic identity, as their mean score was 3.92, while boys scored 3.62. The results clearly corroborated findings and conclusions drawn by other scholars. School and community partnership contributed to the healthy ethnic identity development of adolescents who were thus encouraged to be more engaged in meaningful school activities. 相似文献

人工智能技术的发展对传统著作权制度带来了显著的冲击。以人工智能生成物著作权第一案为例,通过审视作品构成要件判断标准发现,独创性始终贯彻以人类作者为中心的评价标准,同时,智力成果要件则是认定人工智能生成物构成著作权法意义上作品与否的重要标准。从人类是否实际参与作品的创作过程来看,多数人工智能生成物不构成作品,而保护人工智能生成物的价值追求与邻接权制度的基本理念相适应,且邻接权制度的扩张趋势也为把人工智能生成物纳入其保护范畴创造了机会。建议立法通过扩张邻接权制度的权利内容与客体类型以对人工智能生成物提供必要保护。而在当前阶段,反不正当竞争法可以为人工智能生成物相关利益主体提供一定限度的过渡保护。 相似文献

This paper disentangles the impact of schools and teachers in influencing achievement with special attention given to the potential problems of omitted or mismeasured variables and of student and school selection. Unique matched panel data from the UTD Texas Schools Project permit the identification of teacher quality based on student performance along with the impact of specific, measured components of teachers and schools. Semiparametric lower bound estimates of the variance in teacher quality based entirely on within‐school heterogeneity indicate that teachers have powerful effects on reading and mathematics achievement, though little of the variation in teacher quality is explained by observable characteristics such as education or experience. The results suggest that the effects of a costly ten student reduction in class size are smaller than the benefit of moving one standard deviation up the teacher quality distribution, highlighting the importance of teacher effectiveness in the determination of school quality. 相似文献

This paper is the first to study pricing and target oriented decision making together in the newsvendor model. Specifically, this paper studies a newsvendor who decides on order quantity and selling price to maximize the probability of achieving both profit and revenue targets simultaneously. First, it is shown that the probability of a newsvendor achieving both targets depends critically on the relative magnitudes of the profit margin and the ratio between the profit target and the revenue target. Second, the closed-form expressions of the optimal order quantity, the optimal selling price, and the maximal profit and revenue probability are obtained. It is shown that if the product has greater price elasticity, the best strategy is always to price lower and order more. 相似文献

Two approaches have been used for designing spatial surveys to detect a target. The classical approach controls the probability of missing a target that exists; a Bayesian approach controls the probability that a target exists given that none was seen. In both cases, information about the likely size of the target can reduce sampling requirements. In this paper, previous results are summarized and then used to assess the risk that Roman remains could be present at sites scheduled for development in Greater London. 相似文献
