As social movements relying on the weak ties found in social networks have spread around the world, researchers have taken several approaches to understanding how networks function in such instances as the Arab Spring. While social scientists have primarily relied on survey or content analysis methodology, network scientists have used social network analysis. This research combines content analysis with the automated techniques of network analysis to determine the roles played by those using Twitter to communicate during the Turkish Gezi Park uprising. Based on a network analysis of nearly 2.4 million tweets and a content analysis of a subset of 5126 of those tweets, we found that information sharing was by far the most common use of the tweets and retweets, while tweets that indicated leadership of the movement constituted a small percentage of the overall number of tweets. Using automated techniques, we experimented with coded variables from content analysis to compute the most discriminative tokens and to predict values for each variable using only textual information. We achieved 0.61 precision on identifying types of shared information. Our results on detecting the position of user in the protest and purpose of the tweets achieved 0.42 and 0.33 precision, respectively, illustrating the necessity of user cooperation and the shortcomings of automated techniques. Based on annotated values of user tweets, we computed similarities between users considering their information production and consumption. User similarities are used to compute clusters of individuals with similar behaviors, and we interpreted average activities for those groups. 相似文献

A significant challenge in fitting metamodels of large-scale simulations with sufficient accuracy is in the computational time required for rigorous statistical validation. This paper addresses the statistical computation issues associated with the Bootstrap and modified PRESS statistic, which yield key metrics for error measurements in metamodelling validation. Experimentation is performed on different programming languages, namely, MATLAB, R, and Python, and implemented on different computing architectures including traditional multicore personal computers and high-power clusters with parallel computing capabilities. This study yields insight into the effect that programming languages and computing architecture have on the computational time for simulation metamodel validation. The experimentation is performed across two scenarios with varying complexity. 相似文献

Background
The expansion of the medicalisation of childbirth has been described in the literature as being a global phenomenon. The vignette described in this paper, selected from an ethnographic study of routine intervention in Saudi Arabian hospitals illustrates how the worldwide spread of the bio-medical model does not take place within a cultural vacuum.Aim
To illuminate the ways in which the medicalisation of birth may be understood and practised in different cultural settings, through a vignette of a specific birth, drawn as a typical case from an ethnographic study that investigated clinical decision-making in the second stage of labour in Saudi Arabia.Methods
Ethnographic data collection methods, including participant observation and interviews. The data presented in this paper are drawn from ethnographic field notes collected during field work in Saudi Arabia, and informed by analysis of a wider set of field notes and interviews with professionals working in this context.Findings
While the medicalisation of care is a universal phenomenon, the ways in which the care of women is managed using routine medical intervention are framed by the local cultural context in which these practices take place.Discussion
The ethnographic data presented in this paper shows the medicalisation of birth thesis to be incomplete. The evidence presented in this paper illustrates how local belief systems are not so much subsumed by the expansion of the bio-medical model of childbirth, rather they may actively facilitate a process of localised reinterpretation of such universalised and standardised practices. In this case, aspects of the social and cultural context of Jeddah operates to intensify the biomedical model at the expense of respectful maternity care.Conclusion
In this article, field note data on the birth of one Saudi Arabian woman is used as an illustration of how the medicalisation of childbirth has been appropriated and reinterpreted in Jeddah, Saudi Arabia. 相似文献44.

Background
Childbirth fear is the most common underlying reason for requesting a caesarean section without medical reason. The aim of this randomised controlled study was to investigate birth preferences in women undergoing treatment for childbirth fear, and to investigate birth experience and satisfaction with the allocated treatment.Methods
Pregnant women classified with childbirth fear (≥60 on the Fear Of Birth Scale) (n = 258) were recruited at one university hospital and two regional hospitals over one year. The participants were randomised (1:1) to intervention (Internet-based Cognitive Behaviour Therapy (ICBT)) (n = 127) or standard care (face-to-face counselling) (n = 131). Data were collected by questionnaires in pregnancy week 20–25 (baseline), week 36 and two months after birth.Results
Caesarean section preference decreased from 34% to 12% in the ICBT group and from 24% to 20% in the counselling group. Two months after birth, the preference for caesarean increased to 20% in the ICBT group and to 29% in the counselling group, and there was no statistically significant change over time. Women in the ICBT group were less satisfied with the treatment (OR 4.5). The treatment had no impact on or worsened their childbirth fear (OR 5.5). There were no differences between the groups regarding birth experience.Conclusion
Women’s birth preferences fluctuated over the course of pregnancy and after birth regardless of treatment method. Women felt their fear was reduced and were more satisfied with face-to-face counselling compared to ICBT. A higher percentage were lost to follow-up in ICBT group suggesting a need for further research. 相似文献45.

Understanding how survivors of complex trauma navigate towards resources can inform the design of interventions and health promotion strategies. However, there are little data on the resilience and help‐seeking experiences of this group or others who have experienced institutional abuse in childhood. This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse (ICA). Twenty‐two survivors of ICA were purposefully recruited from community organisations in the UK and data were collected via semi‐structured interviews. As a result of negative initial help‐seeking experiences in Ireland, most participants engaged in long periods of self‐management and disclosed information about their childhood as part of a redress scheme in later life. Outside of this scheme, turning points, such as illness or family problems, and the needs of children were influential in seeking help. Peer support networks played an important role as a trusted signposting pathway towards formal interventions. Participants identified interpersonal barriers to formal help‐seeking as helping professionals' failure to share control, insensitivity to identity loss and literacy issues, and the lack of explicit boundaries. The paper concludes with a discussion about the implications for research and future practice.
‘This empirical study sets out to illustrate the help‐seeking experiences of Irish emigrant survivors of institutional childhood abuse’Key Practitioner Messages:
- Turning points, such as illness and bereavement, and the desire to provide for children, influence the help‐seeking of survivors of ICA.
- Irish emigrant survivors of ICA cite failure to share control, insensitivity to identity loss, literacy issues and the lack of explicit boundaries as barriers to help‐seeking.
- General awareness of ICA can help practitioners in low‐threshold services prevent against culturally insensitive practice.
- Peer support networks can provide uniquely trusted signposting towards formal interventions.

Guided by the Common Ingroup Identity Model ( S. L. Gaertner & J. F. Dovidio, 2000 ) and Communication Accommodation Theory ( C. Shepard, H. Giles, & B. A. LePoire, 2001 ), we examined the role of identity accommodation, supportive communication, and self‐disclosure in predicting relational satisfaction, shared family identity, and group salience in multiracial/ethnic families. Additionally, we analyzed the association between group salience and relational outcomes as well as the moderating roles of multiracial/ethnic identity and marital status. Individuals who have parents from different racial/ethnic groups were invited to complete questionnaires on their family experiences. Participants (N = 139) answered questions about relationships with mothers, fathers, and grandparents. The results of the multilevel modeling analyses are discussed in terms of implications for understanding multiracial/ethnic families and family functioning. 相似文献
