ABSTRACT

This study aimed to advance theoretical and practical knowledge of political public relations and mediated public diplomacy through analyzing the agenda-building relationships between state-owned media and foreign news coverage in 16 countries during the 2014 Hong Kong protest. The results indicated significant correlations of issues and stakeholders between the Chinese state-owned media and the English language media outlets of 16 foreign countries, thereby supporting the international agenda-building role of Chinese state-owned media. An exploratory analysis was conducted to test the role of intercultural or international relations variables in the agenda-building process.  相似文献

We model two‐candidate elections in which (1) voters are uncertain about candidates' attributes; and (2) candidates can inform voters of their attributes by sending advertisements. We compare between political campaigns with truthful advertising and campaigns in which there is a small chance of deceptive advertising. Our model predicts that voters should vote in‐line with an advertisement's information. We test our model's predictions using laboratory elections. We find, in the presence of even a small probability that an advertisement is deceptive, voters become substantially more likely to elect a “low‐quality” candidate. We discuss implications of this for existing models of voting decisions. (JEL C92, D72, D82)  相似文献

Social network sites (SNS) have become increasingly pervasive in the daily lives of adolescents. This study explores the relationship between SNS use and perceived online social capital among adolescents using survey data from Australia and Korea. We conducted a face-to-face survey of adolescents (12–15-year-olds) in major cities in Australia (N?=?401) and Korea (N?=?644) in 2013. There was no significant difference in time spent on SNS between adolescents in the two countries; however, significant differences in the way adolescents use SNS were found. Australian adolescents tended to use SNS for group activities, whereas Koreans used it for social monitoring. There was a positive relationship between SNS use and online social capital in both countries. However, the types of social capital that were found to have a strong relationship to SNS use were different. Among Australian adolescents, SNS activities had a higher correlation with bonding social capital compared to bridging capital, whereas the result was contrasting among Korean adolescents. The impact of SNS use on online social capital differed between the two countries, showing that Australian adolescents reporting low SNS use gained online social capital if they used SNS more intensely. Finally, the impact of SNS use and culture on perceived online social capital was examined by conducting hierarchical multiple regressions. Interpersonal communication and group activities emerged as significant predictors of online social capital.  相似文献

A research gap exists with regard to examining the influence of career interventions and career readiness assessments on student retention in college majors related to science, technology, engineering, and mathematics (STEM). To address this gap, the authors examined 3 variables as potential predictors of retention in STEM‐related majors: (a) a STEM‐focused career planning intervention, (b) students' initial major declarations, and (c) changes in scores on a measure of career readiness. Results revealed that all 3 independent variables were significant predictors of STEM retention but did not accurately predict students who would not be retained. These results have implications for undergraduate STEM initiatives, college counselors and career advisors, and researchers investigating the predictors of STEM retention. Future research should include additional predictor variables.  相似文献

We present a counterexample to a lower bound for the power domination number given in Liao (J Comb Optim 31:725–742, 2016). We also define the power propagation time, using the power domination propagation ideas in Liao and the (zero forcing) propagation time in Hogben et al. (Discrete Appl Math 160:1994–2005, 2012).  相似文献

We analyze the effects of property rights and the resulting loss aversion on contest outcomes. We study three situations: in “gain” two players start with no prize and make sunk bids to win a prize; in “loss” both the players start with prizes and whoever loses the contest loses their prize; and in “mixed” only one player starts with a prize that stays with him if he wins, but is transferred to the rival otherwise. Since the differences among the treatments arise only from framing, the expected utility and the standard loss aversion models predict no difference in bids across treatments. We introduce a loss aversion model in which the property rights are made salient, and as a result the reference point varies across treatments. This model predicts average bids in descending order in the loss, the mixed, and the gain treatment; and higher bids by the player with property rights in the mixed treatment. The results from a laboratory experiment broadly support these predictions. There is no significant difference in bids in the loss (gain) treatment and bids by property rights holder (nonholder) in the mixed treatment. A model incorporating both loss aversion and social preferences explains this result. (JEL C91, C72, D23, D74)  相似文献

Background

Maternity care is facing increasing intervention and iatrogenic morbidity rates. This can be attributed, in part, to higher-risk maternity populations, but also to a risk culture in which birth is increasingly seen as abnormal. Technology and intervention are used to prevent perceived implication in adverse outcomes and litigation.

Question

Does midwives’ and obstetricians’ perception of risk affect care practices for normal birth and low-risk women in labour, taking into account different settings?

Methods

The research methods are developed within a qualitative framework. Data were collected using semi-structured interviews and analysed thematically. A purposive sample of 25 midwives and obstetricians were recruited from three maternity settings in Ireland. This included obstetric-led hospitals, an alongside midwifery-led unit and the community.

Findings

Midwifery is assuming a peripheral position with regard to normal birth as a progressive culture of risk and medicalisation affects the provision of maternity care. This is revealed in four themes; (1) professional autonomy and hierarchy in maternity care; (2) midwifery-led care as an undervalued and unsupported aspiration; (3) a shift in focus from striving for normality to risk management; and (4) viewing pregnancy through a ‘risk-lens’.

Discussion

Factors connected to the increased medicalisation of birth contribute to the lack of midwifery responsibility for low-risk women and normal birth. Midwives are resigned to the current situation and as a profession are reluctant to take action.

Conclusion

Improved models of care, distinct from medical jurisdiction, are required. Midwives must take responsibility for leading change as their professional identity is in jeopardy.  相似文献
