Desde 1982 las sátiras de Guadalupe Loaeza han servido como radiografía de la sociedad mexicana durante los años de crisis económica de 1982-al presente. Mientras otras escritoras como Christina Pacheco y Elena Poniatowska se afanan por pintar la cruda realidad de las masas, Loaeza se concentra en los excesos de la burguesía—en su pretensión, materialismo y corrupción—como materia prima para poner de relieve el gran abismo que existe entre las clases sociales en México. Debido a la inmensa popularidad de sus artículos, Loaeza se ha convertido en cronista de la burguesía capitalina moderna, cuyo poder social y político se ve cada vez más amenazado por la crisis económica y la inestablilidad del gobierno. 相似文献

The Antecedents of Menarcheal Age: Heredity, Family Environment, and Stressful Life Events 总被引:5,自引:0,他引:5
Variations in pubertal timing, specifically age at menarche, have been associated with several antecedents, both genetic and environmental. Recent research has considered a broader range of environmental stressors and their influence on the development of the reproductive system. In this investigation, the following possible antecedents were considered: ( a ) hereditary transmission, ( b ) weight and weight for height, ( c ) stressful life events, ( d ) family relations, ( e ) absence or presence of an adult male in the household, and ( f ) psychological adjustment. Subjects were 75 premenarcheal girls between the ages of 10 and 14 drawn from a larger longitudinal investigation of adolescent development. Girls were from white, well-educated, middle- to upper-middle-class families and attended private schools in a northeastern urban area. While breast development, weight, family relations, and depressive affect were predictive of age at menarche, family relations predicted age at menarche above the influence of breast development or weight. A trend for maternal age at menarche to predict adolescent's age at menarche was found. Weight for height, presence of an adult male in the household, and stressful events were not predictive of age at menarche. These complex interactions of biological and psychosocial development demonstrated here may account to some extent for the inter- and intraindividual variation observed in pubertal development. 相似文献

Infants' Responses to Frustrating Situations: Continuity and Change in Reactivity and Regulation 总被引:1,自引:1,他引:1
We examined continuity, stability, and change in behaviors reflecting infant reactivity and regulation. Healthy infants were observed in laboratory situations designed to elicit frustration when they were 5 ( N = 87) and 10 months of age ( N = 82) Behaviors indicative of reactivity included objective ratings of average intensity cry, peak intensity cry, and latency to cry. In addition, durations of orienting, avoidant, and nonnegative communicative behaviors were assessed as measures of regulation at each age. Results showed that several behaviors changed in level over time. In addition, Confirmatory Factor Analysis revealed both structural continuity and discontinuity: Behaviors were organized into 2 similar factors at 5 and 10 months (Reactivity and Regulation), but the relation between reactivity and regulation became increasingly independent over time, such that reactivity and regulation were negatively correlated at 5 months but not at 10 months. Finally, model-fitting revealed cross-dimension but not within-dimension stability (5-month reactivity predicted 10-month regulation). 相似文献

This study investigated the effects of teachers’ use of focus questions on students’ knowledge structures and classroom teaching-learning process by re-analyzing selected data from a quasi-experimental pre-post video study (Wadouh, 2007). Focus questions are content-related anchoring questions highlighting the key content taught in individual lessons (Forbes & Davis, 2010). In Wadouh’ study, students answered a knowledge test before and after the lesson on “blood and the circulatory system” and one lesson per teacher was videotaped to investigate teaching practices in grade 9 biology classrooms. Students also completed a post-unit concept mapping exercise and a motivation-interest questionnaire. In this study, 30 lesson videos selected from 47 were re-analyzed for teachers’ use of focus questions—no focus questions, non-specific or simple focus questions, and specific and challenging focus questions. Individual students’ scores in the concept mapping exercise were aggregated as students’ topic-related knowledge structure. Multilevel analyses revealed a significant positive effect of teachers’ use of specific and challenging focus questions on students’ topic-related knowledge structure. Furthermore, a comparative case analysis of the classroom teaching-learning process was conducted in four lessons where teachers used specific and challenging focus questions in two of the lessons and non-specific or simple focus questions in the other two lessons. The findings indicate that specific and challenging focus questions anchored lessons on students’ co-construction of scientific explanations by activating their pre-instructional ideas, whereas non-specific or simple focus questions anchored lessons on their accumulation of canonical scientific knowledge. This study’s limitations and implications for teacher education reform are discussed. 相似文献

AbstractWhile the scholarly work on the second generation of immigrants has scrutinised both high educational achievers and marginalised groups, less attention has been paid to those in between and their aspirations. In this article, we draw on interviews with 35 adolescents pursuing vocational education in Norway. Our analysis takes as its point of departure a seemingly recurring paradox throughout the interviews. While all the interviewees are in their second year of vocational training, the majority express aspirations of moving beyond vocational occupations and attaining higher education. Building on the scholarship on class and moral worth, we argue that classificatory struggles about value represent an important but often overlooked context of integration. When the students position themselves as individuals who will move on to higher education, their aspirations can be understood as acts of self-constitution and moral boundary work. 相似文献

The growing awareness of serious difficulties in the learning of energy issues has produced a great deal of research, most
of which is focused on specific conceptual aspects. In our opinion, the difficulties pointed out in the literature are interrelated
and connected to other aspects (conceptual as well as procedural and axiological), which are not sufficiently taken into account in previous research. This paper aims to carry
out a global analysis in order to avoid the more limited approaches that deal only with individual aspects. From this global
analysis we have outlined 24 propositions that are put forward for debate to lay the foundations for a profound reorientation
of the teaching of energy topics in upper high school courses, in order to facilitate a better scientific understanding of these topics, avoid many students’ misconceptions and enhance awareness of the current situation of planetary
emergency.
This paper has been conceived as a contribution to the Decade of Education for Sustainable Development, established by the
UN General Assembly for the period 2005–2014. 相似文献

This article reports on an innovative pedagogical approach within the Learning Partnerships program in which school students help to ‘teach the teachers’ within pre-service teacher education. Classes of school students join with classes of pre-service teachers to provide input on how teachers can enhance school students’ engagement and wellbeing. The article draws on data collected from 125 students (aged 13–16) and 120 pre-service teachers in these workshops. Findings generated from a mixed methods study combining pre-workshop focus groups (n = Students: 38, Teachers: 33) and post-workshop focus groups (n = Students: 69, Teachers: 15) and post-workshop surveys (n = Students: 96; Teachers: 101) demonstrated that the workshops were mutually beneficial for both students and pre-service teachers. Participants found that workshopping together enhanced their belief in the possibility of positive student–teacher relationships. The pre-service teachers reported greater confidence in communicating with young people about the issues that affect student engagement and wellbeing. The school students reported that they were more willing to use teachers as a source of help. Implications include the need for increased attention to a ‘third space’ for learning in teacher development which provides opportunity for learning with and from young people about how to foster their engagement and wellbeing. 相似文献
