Prior research supports an association between callous‐unemotional (CU) traits with relational bullying, but evidence associating CU traits with relational victimization is limited. Further, the relationship between CU traits with relational “bully,” “bully‐victim,” and “victim” classifications has been largely neglected. The current study addresses these critical gaps in the literature using a cross‐national study design. The sample comprised of 1887 (51.5% of girls) Greek and Cypriot children (MAge = 11.17) who completed a battery of self‐report measures. Group differences suggested that children in the relational bully and bully‐victim groups scored higher on CU traits compared to children in the victim and low‐risk groups. Although these associations were similar across countries, boys in Greece were more likely to be identified in the bullying only group. In contrast, boys in Cyprus represented the higher percentage identified as bully‐victims and girls in Cyprus represented the higher percentage identified as victim‐only. Regression analysis results indicated that CU traits predicted relational bullying but not victimization. Notwithstanding, other important unexamined factors known to contribute to relational bullying and victimization, our findings suggest that prevention efforts should consider CU traits in order to protect youth from relational bullying. However, differences between countries and gender should also be taken into account.  相似文献

Aim

Having a known midwife at birth is valued by women across the world, however it is unusual for women with fear of childbirth to have access to this model of care. The aim of this study was to describe the prevalence and factors related to having access to a known midwife for women referred to counseling due to childbirth fear. We also wanted to explore if women’s levels of childbirth fear changed over time.

Methods

A pilot study of 70 women referred to counseling due to fear of birth in 3 Swedish hospitals, and where the counseling midwife, when possible, also assisted during labour and birth.

Results

34% of the women actually had a known midwife during labour and birth. Women who had a known midwife had significantly more counseling visits, they viewed the continuity of care as more important, were more satisfied with the counseling and 29% reported that their fear disappeared. Fear of birth decreased significantly over time for all women irrespective of whether they were cared for in labour by a known midwife or not.

Conclusions

Although the women in the present study had limited access to a known midwife, the results indicate that having a known midwife whom the women met on several occasions made them more satisfied with the counseling and had a positive effect on their fear. Building a trustful midwife–woman relationship rather than counseling per se could be the key issue when it comes to fear of birth.  相似文献

Colombia has a unique history, which has been heavily conditioned by armed conflict lasting more than 50 years. This study examines the institutional conditions for success and failure in reducing poverty in Colombian departments by considering changes that took place between 2003 and 2014. Fuzzy‐set qualitative comparative analysis identifies the changes in regional conditions that reduce poverty over time. The pathways for poverty reduction are multidimensional, and many involve changes in institutional attributes such as government transparency, absence of violence, and electoral turnout. The framework developed in this paper can be used to monitor necessary and sufficient pathways in regional clusters.  相似文献

We analyse the evolution of vertical and horizontal inequality in Ecuador in the long-run (1990–2016), as well as during and after the recent commodities boom (2005–2014). Using data from censuses, living standard measurement surveys, and employment surveys we show that Ecuador has made significant progress in reducing inequality, particularly since 2000. However, inequality has not decreased further since 2011. We argue that a key factor behind the reduction and ensuing stagnation of inequality is the dynamic of oil revenues, particularly regarding its effect on economic growth and on the financing of redistributive policies. Using the decomposition of the Gini coefficient by income source proposed by Lerman and Yitzhaki (Rev Econ Stat 67:151–156, 1985) we show that during the last decade there has been a shift away from market sources towards sources of income derived from government expenditures. Following the end of the commodities boom, this process is no longer sustainable. Indeed, we show that the underlying causes that led to the change in the sources of income started long before the end of the boom. The temporary shock following the 2008 financial crisis already affected the structure of Ecuador’s public finances and its current account. And, since around 2011, its institutions and labour market indicators have also deteriorated. We conclude that sustainable inequality reductions require improving the current institutions.

In kindergarten, meals are framed and regulated by the adults and ideas within the institution. However, by inviting children to visualise their ideas, they can be included when trying to understand as well as develop the meals. The purpose was to explore children's pictures of good and desirable meals in kindergarten by using a visual, participatory approach together with children four to six years. The children related to various aspects of the meal, emphasising the importance of food, table artefacts and context, defined as platescape, tablescape and roomscape. The result further highlighted the complexity of listening to the plurality of children's voices.  相似文献

The linear regression model is commonly used by practitioners to model the relationship between the variable of interest and a set of explanatory variables. The assumption that all error variances are the same (homoskedasticity) is oftentimes violated. Consistent regression standard errors can be computed using the heteroskedasticity-consistent covariance matrix estimator proposed by White (1980). Such standard errors, however, typically display nonnegligible systematic errors in finite samples, especially under leveraged data. Cribari-Neto et al. (2000) improved upon the White estimator by defining a sequence of bias-adjusted estimators with increasing accuracy. In this paper, we improve upon their main result by defining an alternative sequence of adjusted estimators whose biases vanish at a much faster rate. Hypothesis testing inference is also addressed. An empirical illustration is presented.  相似文献

This article advances theory on social movements’ strategic adaptation to political opportunity structures by incorporating a narrative perspective. Our theory explains how people acquire and use knowledge about political opportunity structures through storytelling about the movement’s past, present, and imagined future. The discussion applies the theory in an ethnographic case study of the climate movement’s mobilization around the UN Climate Summit in Paris, 2015. This analysis demonstrates how a dominant narrative of defeat about the prior protest campaign in Copenhagen, 2009 shaped the strategizing process. While those who experienced Copenhagen as a success preferred strategic continuity, those who experienced defeat developed a “Copenhagen narrative” to advance strategic adaptation by projecting previously experienced threats and opportunities onto the Paris campaign. Yet by relying on a retrospective narrative, movement actors tended to overlook emerging political opportunities. We demonstrate that narrative analysis is a useful tool for understanding the link between structure and agency in social movements and other actors affected by (political) opportunity structures.

Relationships between species and their environment are a key component to understand ecological communities. Usually, this kind of data are repeated over time or space for communities and their environment, which leads to a sequence of pairs of ecological tables, i.e. multi-way matrices. This work proposes a new method which is a combined approach of STATICO and Tucker3 techniques and deals to the problem of describing not only the stable part of the dynamics of structure–function relationships between communities and their environment (in different locations and/or at different times), but also the interactions and changes associated with the ecosystems’ dynamics. At the same time, emphasis is given to the comparison with the STATICO method on the same (real) data set, where advantages and drawbacks are explored and discussed. Thus, this study produces a general methodological framework and develops a new technique to facilitate the use of these practices by researchers. Furthermore, from this first approach with estuarine environmental data one of the major advantages of modeling ecological data sets with the CO-TUCKER model is the gain in interpretability.  相似文献

Research indicates that a number of psychosocial interventions are effective for reducing behavioural problems in youth. These interventions are now often included on best practice lists aiming to facilitate informed treatment choices among practitioners. However, analyses in neighbouring research areas have highlighted serious shortcomings in how primary studies are analysed and how studies are synthesised in research reviews. This study took a closer look at the evidence of efficacy for psychosocial interventions that aim to reduce behavioural problems in youth, as shown in systematic research reviews by the Cochrane and the Campbell Collaborations (n = 8). The findings suggest a bias towards overemphasising the efficacy of the interventions in several reviews, an over‐confidence in the validity of the findings in some reviews and, overall, a somewhat uncertain evidence base for the efficacy of the interventions. Systematic reviews are crucial for summarising research but more attention to methodological issues may be needed in this area.  相似文献
