Twenty years after the conclusion of the Ecumenical Decade of the Churches in Solidarity with Women, this article considers the development and the need for inclusion of gender in the sphere of theological reflection and education in Latin America and the Caribbean. Rather than a historical account, it proposes an approach that works toward thinking about and developing a new form of relationship between women and men, and between them and today's society and church.  相似文献

Earthquakes are unpredictable events, thus seismic preparedness of households should be fostered, considering the specific needs of each family. Children, for example, are particularly vulnerable to disasters and to the effects of their consequences, but can also act as promoters of preparedness within families. Being part of a wider research, this qualitative study intends to better understand seismic preparedness within families with children in S. Miguel, the largest and most populated island of the volcanic archipelago of the Azores. Two semi-structured interviews were conducted. The first interview was conducted with 125 family representatives, addressing their current preparedness measures. From these representatives, 105 families that had non-existent or insufficient preparedness were selected for a second interview. In the time between the two interviews, the families were instructed to develop seismic preparedness measures. The process of development of these measures was also assessed. Data were analysed using content analysis and frequency analysis. Results point to low levels of preparedness, both at the time of the initial interview and developed subsequently, and families adopted few preparedness measures specifically targeting their children's needs. The results highlight, therefore, that household seismic preparedness should be promoted, with clear indications regarding preparedness specifically for families with children.  相似文献

The literature provides solid documentation of the negative consequences of poor psychosocial functioning and behavioral problems in early childhood. Children facing economic disadvantage are at higher risk for poor socio-emotional development and problem behaviors, which draws attention to the need for prevention targeted at this risk group. The aim of our study was to analyze the impact of an evidence-based teacher-training program, the Incredible Years Teacher Classroom Management (IY-TCM), on the behavior of economically disadvantaged Portuguese children. Participants were 1030 children aged 3–6 years, from 65 preschool classrooms selected for their high percentage of children from economically disadvantaged backgrounds. The study followed an experimental randomized controlled between-group design, with pre- and post-intervention assessments. Teachers in the experimental group attended the IY-TCM program, implemented in six monthly workshops, and four sessions of individual in-class support. Children outcomes were evaluated with the Preschool and Kindergarten Behavior Scales—2nd Edition (Social Skills and Problem Behavior scales). After the intervention, preschoolers in the IY-TCM classrooms showed more improvements in their social skills and more decreases in problem behavior. Children with lower levels of social skills (high risk) at pre-intervention and those coming from families in economic need showed greater improvements in social skills, but these effects were not observed for problem behavior. Results support the growing evidence of the effectiveness of the IY-TCM as a stand-alone, non-adapted program in a Portuguese cultural context, which can play a protective role in children’s lives and thus bridge the gap between children coming from different economic backgrounds.  相似文献

Recognition of predation risk from cues released from injured heterospecific could be beneficial when prey belongs to the same prey guild. Here, we performed three experiments. Experiment 1 showed that P. thaul tadpoles reduced their activity levels when exposed to conspecific injury cues, but not when exposed to amphipod injury cues. Experiment 2 tested whether P. thaul tadpoles can learn to recognize predation risk from chemical cues released from injured heterospecifics from the same prey guild (amphipod, Hyalella patagonica). A group of tadpoles were conditioned by exposing them to a specific concentration of amphipod injury cues paired with conspecific injury cues. Two days later, we evaluated changes in the activity of tadpoles when they were exposed to amphipod cues. As a control of learning, we used an unpaired group. Additionally, we used more control groups to fully investigate the learning mechanism. Our results showed that tadpoles can learn to recognize predation risk from injured amphipods and that the mechanism underlying the observed learned response could be associative. Experiment 3 replicated Experiment 2 and also showed that a low concentration of amphipod cues did not sustain that learning.  相似文献

Differential‐reinforcement‐of‐low‐rate (DRL) schedules are used to decrease the overall rate of, but not eliminate, a target response. Two variations of DRL, spaced‐responding and full‐session, exist. Preliminary comparative analyses suggest that the two schedules function differently when unsignaled. We compared response rates under these two DRL variations with and without signals. In Experiment 1, five preschool students played a game in which points were earned under DRL schedules. In some sessions, a stimulus signaled when responses would be reinforced (S+) or not reinforced (S‐). In others, only an S‐ was present. Signals (S+/S‐) facilitated and maintained responding in both types of DRL schedules. In Experiment 2, we modified the signals with five different preschoolers. Instead of an S‐ only, we did not present any signals. Elimination and high variability of the target response were observed with the S‐ only and absence of S+/S‐, respectively. Signaled DRL schedules are recommended for application.  相似文献

The aim of the present study was to investigate the relationship between mental toughness, stressor appraisal, coping strategies and coping effectiveness among a sample of athletes. Participants were 482 athletes (male n = 305; female n = 177), aged between 16 and 45 years (M age = 20.44 years, SD = 3.98). In support of a priori predictions, mental toughness was associated with stress intensity and control appraisal, but not the type of stressor experienced by athletes. Total mental toughness and its six components predicted coping and coping effectiveness in relation to the self-selected stressor. In particular, higher levels of mental toughness were associated with more problem-focused coping, but less emotion-focused and avoidance coping. Coping effectiveness was influenced by the coping strategy employed by the athletes.  相似文献

Laboratory studies have routinely demonstrated that testing often leads to greater learning and retention than repeated studying. In the classroom, this effect has been replicated with memory and application tasks. However, studies of classrooms involving mathematical problem solving are sparse and have had mixed results. This paper presents the results of a quasi-experimental study in an undergraduate science, technology, engineering, and mathematics course that investigated more frequent testing that incorporated aspects of mastery testing and second-chance testing. Students in the frequent testing cohort scored seven percentage points higher and earned twice the number of As and half the number of failing grades. The advantage of frequent second-chance mastery testing was found for both multiple-choice and free-response questions and remained after controlling for differences in student ability. Women and underrepresented minority students benefited from the altered testing environment to the same extent as the general population.  相似文献
