The current longitudinal study is the first comparative investigation across low‐ and middle‐income countries (LMICs) to test the hypothesis that harsher and less affectionate maternal parenting (child age 14 years, on average) statistically mediates the prediction from prior household chaos and neighborhood danger (at 13 years) to subsequent adolescent maladjustment (externalizing, internalizing, and school performance problems at 15 years). The sample included 511 urban families in six LMICs: China, Colombia, Jordan, Kenya, the Philippines, and Thailand. Multigroup structural equation modeling showed consistent associations between chaos, danger, affectionate and harsh parenting, and adolescent adjustment problems. There was some support for the hypothesis, with nearly all countries showing a modest indirect effect of maternal hostility (but not affection) for adolescent externalizing, internalizing, and scholastic problems. Results provide further evidence that chaotic home and dangerous neighborhood environments increase risk for adolescent maladjustment in LMIC contexts, via harsher maternal parenting.  相似文献

The present study aimed to verify the association between maternal depression and emotional and behavioral problems in school children in Pelotas, Southern Brazil, considering that maternal depression increases children’s vulnerability for developing psychiatric disorders. This is a cross-sectional study with a school-based sample conducted between August 2015 and November 2016 and it is part of a major project entitled ‘Healthy Childhood in Context: A Multidisciplinary Investigation’. Schoolchildren aged between 7 and 8 years and one of their respective parents or a primary caregiver were included in the study. Maternal depression was assessed using the Mini International Neuropsychiatric Interview (MINI). The presence of emotional and behavioral problems in children was verified by the Strengths and Difficulties Questionnaire (SDQ) – parents version. Children of depressed mothers exhibited higher mean scores in all SDQ domains and in the total score when compared to children of non-depressed mothers. Lower socio-economic status was also associated with higher SDQ scores. Our results showed the effects of both maternal depression and poverty on children emotional and behavioral problems, which evidence the need for child mental health preventive care, and free quality assistance for both mothers and their children.  相似文献

The aim of this study was to examine the use of video playback with student teachers to promote teacher learning and to analyse patterns of reflection. A total of 14 student teachers video recorded their lessons in the practice setting and later confronted their performance, facing their videotaped lesson during the course of an interview with their university supervisor. The interviews were then transcribed and coded. Our results indicate that video playback facilitates student teacher learning and that the quality of reflection ranges from routine to dialogic. This suggests that further research into how to elicit higher levels of reflection is needed. The role of the supervisor in promoting deeper thinking should be further examined.  相似文献

This paper addresses the greatest aspiration of the transhumanist movement: achieving immortal life through a procedure known as mind uploading. This procedure consists in keeping our minds fully and indefinitely operative after death by transferring them to a non-biological substrate that allows man to be liberated from his bodily confinement. My main thesis is that the mind uploading project presupposes a secular eschatology, consummating the Promethean utopia according to which human beings could redeem themselves, expelling God definitively from their existential horizon. On this basis, the paper offers meaningful contrasts between the uploading as secular eschatology and the Christian tradition.  相似文献

There is a need to explore variations in children’s safety perceptions for different settings (home, school and neighbourhood) and their relationship with subjective well-being (this including satisfaction with safety and satisfaction with life as whole) by comparing a variety of cultural contexts. A further objective is to explore to what extent gender, age group (10 and 12-year-olds) and level of SWB (measured using the SLSS -Student’s Life Satisfaction Scale- and the BMSLSS -Brief Multidimensional Student’s Life Satisfaction Scale) play a role in this prediction. Results obtained through binary logistic models with samples from Spain (n = 2,724), Algeria (n = 2432), South Africa (n = 2192) and Israel (n = 1914), show that children’s perceptions of safety are predicted by their different perceptions and evaluations of school, home and the nearby area. Perceptions of safety in the nearby area and satisfaction with safety (O.R. = 1.080) contribute to predicting higher levels of satisfaction with life as a whole to a greater extent than scores on the SLSS (O.R. = 1.036) and the BMSLSS (O.R. = 1.050) scales. The country participants live in (especially when combined with satisfaction with safety) and, to a lesser extent gender, also make important contributions. The age group they belong to plays a significant role in predicting higher perceptions of safety at home, in the area nearby, at school, and in predicting higher satisfaction with safety. Results open the door to the introduction of specific interventions (e.g. improving parent-child communication, enhancing public spaces for children to play and promoting children’s participation at school), aimed at promoting higher satisfaction with safety and also indirectly at higher satisfaction with life as a whole, on the basis of achieving positive changes of those factors which make the highest contribution.

Feeling support from the community is a vital aspect of adolescents’ quality of life. Negative experiences at school, such as bullying and cyberbullying can have an adverse impact on adolescents’ life satisfaction that can expand to different domains of their lives including community variables. The goal of the present study was to examine the association between peer victimization, life satisfaction and community support among Chilean adolescents. We used a sample of 497 youths enrolled in grades 9 to 12 of public and private schools in different Chilean districts. Results indicate a negative association between bullying and cyberbullying behavior on community support through life satisfaction. Peer victimization can have negative consequences for youths at a personal level on their assessments of life satisfaction, which can expand to feeling less support from the community. Feeling less support from the community can be detrimental to healthy youth development and adolescents’ quality of life. Community prevention efforts can thus provide emotional support for youth victims of bullying and cyberbullying.
