This article presents data from a study of Syrian diaspora organizations providing assistance to conflict‐affected Syrians in Europe, the Middle East, and North America. Using interview data from leaders in four Syrian diaspora non‐profit organizations, this article examines the social mechanisms used to ensure accountability within the challenging environments where the organizations operate. We find that Syrian diaspora organizations benefit from informal social accountability mechanisms that derive from individuals’ social network ties. Personal, social forms of accountability are particularly valuable to these organizations because these mechanisms help circumvent uncertainty and challenges in the operational environment. These findings reflect an important theme in the extant literature on diaspora philanthropy: diaspora members may have an advantage over other actors because of dense personal networks that make them adept at identifying dependable partners and enforcing agreements even in places where banking and legal systems are fragile.  相似文献

Disordered gambling is best conceptualized as a continuum of severity. Previous research has demonstrated the utility of studying individuals at all points of this spectrum. The sequence of the development of gambling problems and change in gambling involvement along this continuum of severity is not well understood. The present study examined the interplay between cognitive distortions and gambling involvement in a population sample recruited in Alberta, Canada. Data from 1372 participants over 4 assessment waves (5 years) were used to generate a 2-factor latent structure using gambling fallacies and gambling involvement measurements. Structural equation modelling showed that cognitive distortions more strongly predicted future gambling involvement than the reverse relationship, using the comparative fit index (CFI) and the root mean square error of approximation (RMSEA) to assess the models. In addition, cognitive distortions declined over time, whereas gambling involvement remained stable. The results of the study suggest that focusing primarily on cognitive mechanisms in public health initiatives for gambling disorders may be a more effective strategy than focusing on behavioural solutions.  相似文献

Despite the fact that sickle-cell disease (SCD) is perhaps the most “racialized” medical condition in the USA, very little is known about how “race” impacts public support for health policies related to the condition. We embedded an experiment within the 2011 Cooperative Congressional Election Study in order to assess perceptions about SCD among 1250 participants from diverse backgrounds and evaluate the extent to which these perceptions were associated with support for government spending on SCD-related benefits. We manipulated the racial phenotype of SCD advocates who requested additional government funding and asked participants to indicate how much the government should provide. Overall, participants expressed moderately positive attitudes about SCD, and there were no differences in funding support based on the race of the advocate. However, white participants supported less funding compared to nonwhite participants, even after adjusting for a number of demographic and attitudinal covariates. These findings suggest that a complex relationship between racial identification and implicit racism may shape public perceptions about SCD that negatively influences perceivers’ support for SCD-related policy.  相似文献

In a recent study, Mahmood and Soon [26] identified and operationalized a set of variables that can be potentially impacted by information technology. The lack of factor analysis to verify the dimensionality of different variables is a notable omission in the study. This paper describes and employs the limited-information factor analysis approach and the minimum average partial criterion for testing the unidimensionality of different variables in the Mahmood and Soon study. While reconfirming the construct validity of eight variables, our results question the unidimensionality of two original variables. Further testimony is provided in favor of our results by citing previous research studies.  相似文献

This study examined how changes in at‐home parents' mental health and parenting practices related to changes in their children's adjustment throughout the course of a service members' military deployment. Participants included at‐home parents from 114 National Guard families who were interviewed at four different occasions across the deployment cycle. The results revealed changes across the deployment cycle among the following three indicators: parental warmth, depressive symptoms, and children's externalizing behaviors. Changes in parental warmth were associated with changes in children's adjustment. Overall, these findings indicate that during parental separation, at‐home parents' responses to children have important implications for children's adjustment.  相似文献

This article investigates how the social media site Reddit hindered the collective action efforts stemming from the Gamergate controversy. Using forum posts from two time-points, one early in the movement and another six months later, this work describes how the Reddit platform impeded movement efforts over time. More specifically, we examine how the nature of Reddit discussions created barriers to each of three key movement processes: narrative construction of collective identity, framing, and boundary work. We argue that unlike social media platforms such as Facebook, some sites–Reddit in this case–may negatively impact movement success depending on its structure. We also discuss the importance of differing ICT structures and implications for online interactions more generally.  相似文献

Problem

Research suggests that the skill and experience of the attendant significantly affect the outcomes of vaginal breech births, yet practitioner experience levels are minimal within many contemporary maternity care systems.

Background

Due to minimal experience and cultural resistance, few practitioners offer vaginal breech birth, and many practice guidelines and training programmes recommend delivery techniques requiring supine maternal position. Fewer practitioners have skills to support physiological breech birth, involving active maternal movement and choice of birthing position, including upright postures such as kneeling, standing, squatting, or on a birth stool. How professionals learn complex skills contrary to those taught in their local practice settings is unclear.

Question

How do professionals develop competence and expertise in physiological breech birth?

Methods

Nine midwives and five obstetricians with experience facilitating upright physiological breech births participated in semi-structured interviews. Data were analysed iteratively using constructivist grounded theory methods to develop an empirical theory of physiological breech skill acquisition.

Results

Among the participants in this research, the deliberate acquisition of competence in physiological breech birth included stages of affinity with physiological birth, critical awareness, intention, identity and responsibility. Expert practitioners operating across local and national boundaries guided less experienced practitioners.

Discussion

The results depict a specialist learning model which could be formalised in sympathetic training programmes, and evaluated. It may also be relevant to developing competence in other specialist/expert roles and innovative practices.

Conclusion

Deliberate development of local communities of practice may support professionals to acquire elusive breech skills in a sustainable way.  相似文献

In this study, we propose a prior on restricted Vector Autoregressive (VAR) models. The prior setting permits efficient Markov Chain Monte Carlo (MCMC) sampling from the posterior of the VAR parameters and estimation of the Bayes factor. Numerical simulations show that when the sample size is small, the Bayes factor is more effective in selecting the correct model than the commonly used Schwarz criterion. We conduct Bayesian hypothesis testing of VAR models on the macroeconomic, state-, and sector-specific effects of employment growth.  相似文献
