This study examined how Turkey uses social media as a tool for public diplomacy and how the state’s soft-power efforts have recently changed on the global stage. The researchers constructed a dataset of 2769 Twitter posts by the Turkish government’s most influential public diplomacy accounts. The analyses revealed that the focus of Turkey’s Twitter public diplomacy has become concentrated on the Middle East and North Africa (MENA) region and is thematically focused on the political values embodied by the Turkish president. The findings suggest that public diplomacy remains to be the diplomacy of the government, not of the public, and social media is used as just another tool for propaganda, not as a means of engagement with foreign publics. Further, the findings indicate the emergence of a “new” cult of personality in public diplomacy and point out the instrumental role of social media in changing the dynamics of leader-follower relationship. The study contributes to public relations theory and practice by advancing the burgeoning public diplomacy scholarship at the intersection of social media and relational approaches.  相似文献

The joint models for longitudinal data and time-to-event data have recently received numerous attention in clinical and epidemiologic studies. Our interest is in modeling the relationship between event time outcomes and internal time-dependent covariates. In practice, the longitudinal responses often show non linear and fluctuated curves. Therefore, the main aim of this paper is to use penalized splines with a truncated polynomial basis to parameterize the non linear longitudinal process. Then, the linear mixed-effects model is applied to subject-specific curves and to control the smoothing. The association between the dropout process and longitudinal outcomes is modeled through a proportional hazard model. Two types of baseline risk functions are considered, namely a Gompertz distribution and a piecewise constant model. The resulting models are referred to as penalized spline joint models; an extension of the standard joint models. The expectation conditional maximization (ECM) algorithm is applied to estimate the parameters in the proposed models. To validate the proposed algorithm, extensive simulation studies were implemented followed by a case study. In summary, the penalized spline joint models provide a new approach for joint models that have improved the existing standard joint models.  相似文献

The Strengths and Difficulties Questionnaire (SDQ) was used to predict the positive and negative affects of emotional and behavioral difficulties among adolescent boys and girls aged between 14 and 21 years living in disadvantaged communities. A total of 316 adolescents—181 boys and 135 girls—living in the Seri Pantai and Pantai Ria Public Housing Projects in Kuala Lumpur were invited to complete the questionnaire. The results showed that conduct and peer problems were the most prevalent emotional and behavioral difficulties experienced by these adolescents. As expected, the emotional symptoms were more common among the girls than the boys. A further analysis showed that emotional symptoms, peer problems, and low prosocial behavior were predictors of the negative affect of emotional and behavioral difficulties while negative emotional symptoms and high hyperactivity were predictors of a positive affect. The findings suggested that three subscales of SDQ are required to produce a negative affect, and two subscales of SDQ for a positive affect.  相似文献

This case study examines a confrontation between WikiLeaks and Bank of America (BOA). Drawing upon Castells’ concept of mass self-communication and the cocreational approach to public relations, a triangulation of social network analysis and event study method allows this project to capture the structure of WikiLeaks’ global network and to document how the activist network affected BOA's stock value. The analysis reveals that WikiLeaks emerged as the center of a global mass self-communication network consisting of a diverse group of members, such as social media sites and mass media outlets. The study offers implications for a re-conceptualization of the role of activism in public relations.  相似文献

Neal, Sirgy and Uysal (1999) developed a model and a measure to capture the effect of tourism services on travelers quality of life (QOL). They hypothesized that travelers overall life satisfaction is derived from satisfaction with the primary life domains (e.g., family, job, health). Specifically, overall life satisfaction is derived from two sources of satisfaction, namely satisfaction with non-leisure life domains and satisfaction with leisure life. Satisfaction with leisure life is derived from satisfaction with leisure experiences that take place at home and satisfaction with travel/tourism experiences. Satisfaction with travel/tourism experiences results from satisfaction with trip reflections of the traveler (e.g., what the traveler remembers regarding perceived freedomfrom control, perceived freedom from work, involvement, arousal, mastery, and spontaneity experienced during the trip) and satisfaction with travel/tourism services. Satisfaction with travel/tourism services was hypothesized further to be derived from satisfaction with the service aspects of travel/tourism phases – pre-trip services, en-route services, destination services, and return-trip services. The model was tested using a study of university faculty and staff. The original model was extended by hypothesizing the moderation effect of length of stay. Specifically, we hypothesized that the relationshipsin the model are likely to be more evident in relation to travelers who have more time to experience the tourism services than those who do not. A survey of 815 consumers of travel/tourism services who reside in Southwest Virginia was conducted. As predicted, the data confirmed hypotheses as established in the original model. Satisfaction with tourism services affects travelers QOL through the mediating effects of satisfaction with travel/tourism experiences, and satisfaction with leisure life. Furthermore, the moderating effect of length of stay was confirmed by the data. In sum, this replication and extension study provided additional validational support of the original tourism services satisfaction measure in relation to QOL-related measures.  相似文献

Background

Women’s mental health in the perinatal period is understudied worldwide and in Arab countries especially.

Aim

This systematic review explores evidence of the association between women’s social resources for empowerment in the Arab World and their mental health in the prenatal and postnatal (≤1 year postpartum) periods.

Methods

Guided by Kabeer’s framework of empowerment, the authors applied a search string in PubMed and Web of Science databases to identify studies in countries of the Arab League (hereafter the Arab World) that address mental health and social resources for women’s empowerment in the perinatal period.

Findings

Of 1865 electronically retrieved articles, 23 met the inclusion criteria. Overall, the majority of studies found a positive association between social resources for empowerment and perinatal mental health. Seven studies explored the relationship between familial or general social support and prenatal mental health in Arab women, and found a significant positive association. Sixteen of the 18 studies of women in the postnatal period found that enabling familial, extra-familial, and/or general social support was positively associated with mental health.

Conclusion

This review demonstrates an association between social resources and perinatal mental health, but there is a dearth of research in this area. We call for additional research on Arab women in the perinatal period using context-specific but standardized tools to assess social resources and mental health. Evidence on positive mental health, resilience, and the influence of social resources can guide the improvement of prenatal and postpartum care services.  相似文献

The purpose of the present study was twofold: (1) to investigate the effects of sexual orientation (heterosexuals and gay men/lesbians) and gender difference on responses to romantic relationship problems (Exit, Voice, Loyalty, and Neglect [EVLN] responses) and of perceived partner’s EVLN responses in Turkey, and (2) to examine whether internalized homophobia was associated with EVLN responses and perceived partner’s EVLN responses for gay men and lesbians. Responses to Dissatisfaction Scale-Accommodation Instrument, Internalized Homophobia, and Demographics Information were administered to 187 participants (44 lesbians, 44 gay men, 53 heterosexual women, 46 heterosexual men).The MANCOVA results showed that men reported higher loyalty than women, whereas women presented more exit responses than men. Further, the interactions between gender and sexual orientation on the participants’ EVLN responses and on the perceived partner’s EVLN responses were significant. With respect to heterosexual women, heterosexual men displayed more loyalty responses. Lesbians had higher scores on loyalty than did heterosexual women. Lesbians also had higher scores on perceived partner’s exit response than did heterosexual women and gay men. On the contrary, heterosexual women reported more perceived partner’s voice response than lesbians. In addition, lesbians reported higher perceived partner’s neglect responses than heterosexual women. Compared to heterosexual women, heterosexual men reported higher perceived partner’s exit response. Finally, internalized homophobia was associated with destructive responses for both lesbians and gay men.  相似文献

This article unveils the voices of the international students of the Universiti Sains Malaysia by exploring their belongingness and community well-being in Malaysia. This study was conducted with 14 international students (seven males and seven females) studying at the Universiti Sains Malaysia for at least a year. A qualitative approach was employed using in-depth case interviews to examine the socio-cultural challenges they experienced while studying abroad. The specific challenges reported among the international students are their well-being in distinct aspects such as physical, mental, and emotional. This study seeks to explore the international students' reliability on conational communities for social support. When achieving belongingness with their conational friends, international students can flourish well in their current community in Malaysia, thus achieving social community well-being although they are far away. Besides maintaining established close friendships, the international students develop a sense of comfort and familiarity by forming new friendships with conational and other international students. Sharing similar backgrounds and nationalities, as well as experiences and struggles, are significant for international students in maintaining close friendships and situational harmony. This study highlighted the meaning behind physical and emotional distance, as well as the situation of “being temporarily abroad” and its relations to intimacy practices and belongingness in close friendships. The results presented in this article contribute to an increasing understanding of international students' challenges and the future of social harmony and community well-being while temporarily living in Malaysia. Correspondingly, as a result of this study, students will be more deferential of cultural differences and cross-cultural sensitivity, which will also help to decrease prejudice and discrimination.  相似文献

As the Horn of Africa is going through major political, societal and cultural transformations, how does photography construct visions that take them into account? This short paper looks then at four recent bodies of work that evoke and revolve around the different perceived temporalities that go along them, raising questions on history, memory, transmission and finally on photography itself.  相似文献
