Social media,legacy media and gatekeeping: the protest paradigm in news of Ferguson and Charlottesville     

Amani Ismail  Gayane Torosyan  Melissa Tully 《The Communication Review》2013,16(3):169-195

ABSTRACT

This study investigates the site of intersection between legacy and social media, whereby it asks how local legacy media (St Louis Post-Dispatch and Richmond Times-Dispatch) invoked social media (Facebook and Twitter) discourse within their coverage of the Ferguson (2014) and Charlottesville (2017) events. It thus explores how gatekeeping is manifested and, consequently, how the protest paradigm emerged in a news landscape of proliferating social media. Thematic textual analysis indicates that coverage of Charlottesville and Ferguson clearly relied on indulging the social media sphere in important ways. Common themes of social media as multipurpose platforms, as interfacing with law and order, and as reconciling material and digital modes culminating in social activism were revealed. The study shows that the protest paradigm that has long characterized legacy media’s coverage of social protest is not as “pure” as it may once have been, since a social media component is helping define the contours and content of legacy media’s landscape.  相似文献   

Maternal Leptin,Adiponectin, Resistin,Visfatin and Tumor Necrosis Factor-Alpha in Normal and Gestational Diabetes

Gestational diabetes mellitus (GDM) is a common medical complication associated with pregnancy. The present study evaluates the changes in maternal adipocytokines (leptin, adiponectin, resistin, visfatin and tumor necrosis factor-alpha; TNF-α) in pregnancy complicated with GDM compared to normal pregnancy at 2nd and 3rd trimesters. The study included total number of 142 pregnant women classified into 4 groups: normal pregnancy (n = 33) and pregnancy with GDM (n = 24) both at 2nd trimester and normal pregnancy (n = 38) and GDM (n = 47) at 3rd trimester. Both GDM groups were significantly presented with elevated body mass index, fasting blood sugar and abnormal oral glucose tolerance test compared to their matched control. Results indicated reduction in maternal serum leptin and adiponectin in GDM compared to normal pregnancy at 3rd trimester. Elevated resistin and TNF-α were evident among pregnancy complicated with GDM at both tested trimesters. On the other hand, significant elevation in maternal visfatin was noted between GDM and matched control at 2nd trimester only. Significant increase in maternal leptin and visfatin and resistin was noted by advances in gestational period in healthy pregnancy. On the other hand, reduced adiponectin and elevated visfatin mean values were noticed in GDM at 3rd compared to 2nd trimester. It could be concluded that increased insulin resistance accompanies GDM is associated with suppressed leptin and adiponectin and increased resistin and TNF-α which might suggest their involvement in the development of GDM.  相似文献

Building community in academic settings: the importance of flexibility in a structured mentoring program     

Robyn Ewing  Mark Freeman  Simon Barrie  Amani Bell  Donna O’Connor  Fran Waugh 《Mentoring & Tutoring: Partnership in Learning》2013,21(3):294-310

Academic mentoring is increasingly being used by many universities as a tool to enhance the quality of research‐led teaching, promote cross‐faculty collaboration and encourage a mentoring culture and community. This article reports on a pilot project established to investigate the benefits of building flexibility into a structured academic mentoring program at the University of Sydney. Twenty‐six academics from the Faculty of Business and Economics and the Faculty of Education and Social Work participated in the program. The mentors ranged in position from lecturer to professor and the mentees from associate lecturer to senior lecturer. Flexible arrangements were shown to be important in a variety of ways, from the pairing of mentor with mentee, to focussing on issues of work survival and life balance, research outcomes and career advancement. The project highlighted the lower number of male academics involved in formal mentoring, which merits further exploration. All participants reported positive outcomes, although refinement of the pairing process was recommended. A variety of unanticipated outcomes was reported by mentees.  相似文献   

A confidence interval test for the detection of structural breaks     

Ismail H. Genc 《Journal of The Franklin Institute》2011,348(7):1615-1626

This paper develops a simple confidence interval test around the first difference of time series data to identify a structural break over time. Simulations show the robustness of the test. We also apply the test to the popular debate on the adoption of inflation targeting in New Zealand. Using the NZ inflation data, our test fails to find a structural break around the adoption date of the inflation targeting policy. The test rather supports an early reaction to the expected policy change. As the effectiveness of inflation targeting is a controversial issue, the insight provided by our test sheds some light on the debate. Our test has a wide range of possible applications in empirical literature.  相似文献

Cluster searching strategies for collaborative recommendation systems     

Ismail Sengor Altingovde  Özlem Nurcan Subakan  Özgür Ulusoy 《Information processing & management》2013

In-memory nearest neighbor computation is a typical collaborative filtering approach for high recommendation accuracy. However, this approach is not scalable given the huge number of customers and items in typical commercial applications. Cluster-based collaborative filtering techniques can be a remedy for the efficiency problem, but they usually provide relatively lower accuracy figures, since they may become over-generalized and produce less-personalized recommendations. Our research explores an individualistic strategy which initially clusters the users and then exploits the members within clusters, but not just the cluster representatives, during the recommendation generation stage. We provide an efficient implementation of this strategy by adapting a specifically tailored cluster-skipping inverted index structure. Experimental results reveal that the individualistic strategy with the cluster-skipping index is a good compromise that yields high accuracy and reasonable scalability figures.  相似文献

Self reported awareness of child maltreatment among school professionals in Saudi Arabia: impact of CRC ratification     

AlBuhairan FS  Inam SS  AlEissa MA  Noor IK  Almuneef MA 《Child abuse & neglect》2011,35(12):1032-1036

Objectives

The Convention on the Rights of the Child (CRC) was ratified by Saudi Arabia 15 years ago; yet addressing the issue of child maltreatment only began in more recent years. School professionals play a significant role in children's lives, as they spend a great deal of time with them and are hence essential to protecting and identifying those in danger or at risk. The objective of this study is to identify school professional's awareness of child maltreatment and the existing national policies and procedures to examine the extent of efforts made in Saudi Arabia and to activate the roles of schools and school professionals in protecting children from violence and implementation of Article 19 of the CRC.

Methods

This was a cross-sectional study, where school professionals from randomly selected schools throughout the country were invited to participate in a self-administered questionnaire.

Results

A total of 3,777 school professionals participated in the study. Fifty-five percent of professionals had at least 10 years of work experience. A low-level of awareness of child maltreatment was found in about 1/3 of school professionals. Only 1.9% of school professionals had ever attended any sort of specific training on child maltreatment, though 69.3% of those who had not, were willing to attend future training. With regards to awareness of CRC Article 19 or policies and procedures addressing child maltreatment, only 22% reported being aware of it.

Conclusion

The majority of school professionals in Saudi Arabia have a low-intermediate level of awareness of child maltreatment, ratification of CRC, and related national policies and procedures, yet most are willing to attend training programs on this subject matter. Efforts need to be made in the country to fill this gap.  相似文献
