Emotion regulation is assumed to play an important role in depressive and anxiety symptoms in youth. However, the role of core components of emotion regulation, such as emotional awareness, is not well understood so far. Thus this meta-analysis aimed to examine the relationship between depressive and anxiety symptoms with emotional awareness in youth. A systematic literature search (PsycINFO, Medline, Google Scholar) identified 21 studies, from which 34 effect sizes were extracted. Results from random effects models showed that difficulties in emotional awareness were significantly correlated with a medium effect size for each, depressive and anxiety symptoms separately, and for their combined effects (overall outcome). Additionally, further analyses revealed that age was a significant moderator of the relationship between emotional awareness with depressive and anxiety symptoms, with younger samples (mean age?≤?12 years) showing a stronger association between difficulties in emotional awareness and depressive and anxiety symptoms as compared to older samples (mean age?>?12 years). The results suggest that emotional awareness may be of relevance for depressive and anxiety symptoms in youth. Future work is required to examine longitudinal developments, moderators, and mediators in multi-method approaches. Moreover, children and adolescents may benefit from interventions that aim to enhance emotional awareness.  相似文献

In the early 1960s, India and Brazil started developing space capabilities covering three major complementary areas: (1) satellites; (2) launch vehicles; and (3) ground systems. More than 50 years later, India is among the most active and successful spacefaring countries and is developing cost-effective space technologies. On the other hand, Brazil still does not possess a launch system and has put into orbit only small and non-commercial satellites, several of them built with Chinese cooperation and launched on Chinese launch vehicles. The goal of this article is to compare Brazilian and Indian space programs, which present different levels of accomplishments. This analysis contains three elements. The first part discusses the two space programs’ evolutions and their contemporary features. The second part compares the space programs’ models from two observation variables: (1) the state administrative organization; and (2) international cooperation in the space sector. Finally, the third part of the article compares the strengths and challenges of each program, highlighting that an international partnership between Brazil and India in space opens a window of opportunity for Brazil to take part in a much wider range of projects than is possible if funded alone.  相似文献

This article provides a review of the theoretical perspectives on civic and political participation. Four distinct views were identified in the literature: (a) The orthodox view: “Civic and political participation are always positive”; (b) The broad view: “Civic and political participation are multidimensional”; (c) The qualitative view: “Civic and political participation are not always good”; and (d) The nonconformist view: “The need to redeem the political dimension of participation.” This article intends to sophisticate simplistic assumptions about civic and political participation and to provide an original organization of the theoretical perspectives in this field. Based on this analysis, this article presents suggestions for an alternative approach to citizenship education.  相似文献

As the COVID-19 lockdowns were implemented, Latin American countries raced to announce plans to address gender-based violence in response to the increase in reports of intrafamily abuse. However, states' interventions had limited results. This article explores the Ecuadorian case. The Andean country's emergency strategy was based on reporting violence via the 911 emergency number, a plan that failed to consider that women quarantined with their aggressors would not have the opportunity to make the call. This article lays bare the extent of the gap between policy and practice in gender mainstreaming and the acute consequences of this during the pandemic.  相似文献

Paid domestic workers (PDWs) in Peru, who are predominantly women, are one of the most vulnerable labour sectors in the country. We argue that an important factor explaining this is linked to national legislation that grants only partial rights to the sector, thus maintaining inferior labour conditions for such workers. Here we share our analysis of a survey of 314 PDWs, conducted between April and May 2020, confirming that PDWs in Peru are highly unprotected, particularly during the COVID pandemic, in which there has been a lack of comprehensive social protection schemes.  相似文献

DNA analysis has been widely used in the forensic field in order to contribute to identifying the perpetrator of a crime. Forensic investigation in sexual assaults usually focuses on locating and identifying biological fluids, followed by DNA analysis. The identification of certain compounds present in condoms can be useful to reconstruct the occurred event, especially in cases of sexual assaults where the DNA analysis did not show the presence of a male profile and where RNA analysis did not show the presence of sperm markers. Herein we describe the case of a woman reporting to be victim of sexual assault, who was not able to provide accurate information concerning the dynamics of the event; she remembered only forced penile–vaginal penetration by a single perpetrator. We performed short tandem repeat (STR) analyses and mRNA typing for forensic genetics testing on vaginal and rectal swabs collected on the victim, and Fourier-transform infrared spectroscopy (FTIR) followed by chromatographic analyses for the detection of condom compounds on the same swabs. The STR analysis showed only the victim’s genetic profile, and RNA analysis showed only the presence of vaginal and skin markers. In this situation, the identification of condom compounds residues on vaginal swabs became important as it complemented other collected evidences allowing the Court to reconstruct the events. A proposal of likelihood ratio (LR) calculation for the assessment of the weight of evidence in this case is described.  相似文献

Abstract

The literature on gender-based discrimination in credit markets is recently expanding, but the results are not yet definitive and have not been generally agreed upon. This paper exploits a new dataset on Barbados, Jamaica, and Trinidad and Tobago, which provides detailed information about female ownership and management in firms for investigating the existence of a gender gap in access to finance. The evidence presented herein suggests that more precise measures of the gender composition of the firm show that women-led businesses are more likely to be financially constrained than other comparable firms.  相似文献

By focusing on the second half of the nineteenth century, the article will demonstrate that girls’ success in public examinations has a long history. It will highlight that opportunities for girls to take such examinations were limited by Victorian perceptions of what might be acceptable for their gender and, more especially, by their social class. The data presented in the article is analysed using a Bourdieusian framework.  相似文献

In Italy, women have long been stereotypically marked as either objects of sexual desire or as producers of new life. This changed radically in the 1970s, when second-wave feminism redefined gender relations and experimented with new paths of life not determined by matrimony and maternity. The legalisation of abortion, during the second half of the decade, is now hailed as one of the primary achievements of the women's movement. A theme closely connected to abortion such as motherhood, on the other hand, seems to have been excluded from the public memory of 1970s feminism. Drawing on the outcomes of an oral history project, this article unearths the dominant discourses and individual and collective silences within the public memory of the 1970s women's movement in the Italian city of Bologna, and explores the processes of creating ‘composure’ among women as they remember their experiences of motherhood and abortion.  相似文献
