Surveys were employed to explore the experiences of children in care and their carers about traditional fostering. They also examined the perspectives of randomly selected adults in the community about the practice of traditional foster care in the Tamale area of northern Ghana. The 74 participants responded to closed- and open-ended interview questions about traditional foster care. Frequencies and thematic grouping of qualitative responses showed that the need to keep family ties alive was the key reason for placement of children with family and kin. Majority of the children expressed satisfaction with living in foster care, even though they had experienced physical and emotional abuse and intimidation. Although most carers were not formally employed and had little personal income, they were positive about having the care role, but faced challenges in providing for many children in a difficult economic situation. The report highlights the role of reciprocity, altruistic and socio-cultural factors in quality of care, and the potential for the traditional kinship foster care to provide suitable avenues of placement for children as recommended by the Ghana child rights law. It also identifies the need for education for carers around children's needs and Ghana's child rights law. 相似文献

A recently identified reflex, termed the “cervico‐motor reflex,” was studied in 15 healthy women (mean age 36.6 years). The response of levator ani (LA) and puborectalis (PR) muscles to electrical and mechanical stimulation of the cervix uteri (CU) was determined. One concentric needle electrode was inserted into the CU (stimulating), a second into the LA (recording), and a third into the PR (recording). The vaginal pressure was measured at rest and on cervical stimulation by balloon‐tipped catheters. Electrical stimulation of the CU led to a reduction in pressure in the upper portion of the vagina (p < .05) and an increase in pressure in the middle and lower portions (p < .001). Stimulation also caused an increase in the electromyographic (EMG) activity of the LA and PR muscles (p < .01). Mechanical stimulation induced the same effects but to a lesser degree. Stimulation of the anesthetized CU, LA, or PR did not evoke the response. The data suggested the presence of a reproducible reflex relationship between the CU and both the LA and PR. During the sexual act and penile buffeting of the CU, levator contraction “balloons” the upper vagina, which acts as a “receptacle” for the semen. Meanwhile, PR contraction narrows the lower vagina, which may effect an increase of penile erection and rigidity. The cervico‐motor reflex may be incorporated as an investigative tool in sexual act disorders. 相似文献

The problem of pooling means is considered based on two samples in presence of the uncertain prior information that these samples are taken from possibly identical populations. Two discrete models, Poisson and binomial are considered in particular. Three estimators, i.e. the unrestricted estimator, shrinkage restricted estimator and estimators based on preliminary test are proposed. Their asymptotic mean squared errors are derived and compared. It is demonstrated via asymptotic results that the range of the parameter space in which shrinkage preliminary test estimator dominates the unrestricted estimator is wider than that of the usual preliminary test estimator. A Monte Carlo study for Poisson model is presented to compare the performance of the estimators for small samples. 相似文献

While more girls are now attending school in Afghanistan than prior to 2010, there is a lack of evidence on how school attendance is helping their cognitive development. We use data from a large sample of all‐girls state‐funded school students to estimate for the first time the “learning profile” for Afghanistan. Students enrolled in grades 4 to 9 were assessed using the Early Grade Reading Assessment (EGRA) and the Early Grade Mathematics Assessment (EGMA) test items. We find that higher grade progression (particularly in grades 6–9) leads to almost no gain in numeracy (addition and subtraction) skills that should have been achieved in early grades. Similar results follow from the analysis of student performance in the EGRA test, particularly in oral reading fluency (correct words read per minute) and oral reading comprehension (number of correct answers out of 12). These findings warn that simply enrolling girls in school without improving the relationship between grade completion and learning is unlikely to transform the lives of women in Afghanistan. 相似文献

This article examines the relationship between empowerment gaps between spouses and children's nutritional status and education using nationally representative data from the 2012 Bangladesh Integrated Household Survey. We measure relative empowerment of spouses using the recently developed Women's Empowerment in Agriculture Index. We find that while gender gaps in empowerment are only linked weakly to children's nutritional status, fathers’ and mothers’ empowerment have different effects on investment in children. Fathers’ empowerment is positively associated with younger children's nutrition and schooling, while mothers’ empowerment is more important for girls’ education in general and in keeping older boys and girls in school. 相似文献

Relatively few studies have attempted to identify factors that contribute to variation in parental behavior. The literature has revealed associations between both internal and external factors in the variation in parenting behaviors. In addition, the vast majority of the existing literature has focused almost exclusively on Western cultures (e.g., the USA). The current study addresses these limitations by examining direct and indirect pathways involving both internal and external sources of influence on parenting behaviors in a sample of adults from Saudi Arabia (N = 196). The employed statistical models revealed robust and consistent direct associations between the examined internalizing sources of influence (self-control and psychopathy) and parenting behaviors. Subsequent models revealed some evidence of mediation stemming from external sources of influence (namely, aggression). However, the resulting indirect effects were inconsistent, indicating that other, unmeasured mechanisms ultimately connect the examined internalizing problems and parenting behaviors. 相似文献

Three forms of a general null hypothesis Ho on the factorial parameters of a general asymmetrical factorial paired comparison experiment are considered. A class of partially balanced designscorresponding to each form of H0 is constructed and the A,D and ioptimal design, minimizing the trace, determinant and largest eigenvalue of a defined covariance matrix of related maximumlikelihoodestimators, in that class is determined. Moreover, the optimal design in each class maximizes the noncentrality parameter λ2 of the asymptotic noncentral chi-square distribution of the likelihood ratiostatistic -2 log λ for testing Ho under defined local alternatives. These results apply directly to symmetrical factorial paired comparison experiments as special casesExamples are given forillustrating applications of the developed results 相似文献
