What is gained and what is left to be done when content analysis is added to network analysis in the study of a social movement: Twitter use during Gezi Park

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.     

Cumulative correspondence analysis of ordered categorical data from industrial experiments

Most studies of quality improvement deal with ordered categorical data from industrial experiments. Accounting for the ordering of such data plays an important role in effectively determining the optimal factor level of combination. This paper utilizes the correspondence analysis to develop a procedure to improve the ordered categorical response in a multifactor state system based on Taguchi's statistic. Users may find the proposed procedure in this paper to be attractive because we suggest a simple and also popular statistical tool for graphically identifying the really important factors and determining the levels to improve process quality. A case study for optimizing the polysilicon deposition process in a very large-scale integrated circuit is provided to demonstrate the effectiveness of the proposed procedure.

Turkey's Education Policies towards Syrian Refugees: A Macro‐level Analysis

This study discusses the transformation of Turkey's education policies towards Syrian refugees in three major stages. It argues that education policies in these different stages reflect the general perception of and political vision for Syrian refugees by the Turkish state, and that they are also instruments through which this political vision is materialized and declared. The remarkable evolution of Turkey's education policies towards Syrian refugees, from early policies that aimed at temporary accommodation to later policies that have aimed at full integration, needs to be understood in this framework of a changing vision in addition to the security concerns. Lastly, the article argues that, while the current strategy of complete integration of Syrians into formal education system is certainly positive, it also brings about a number of significant challenges related to the political and legal context in Turkey that will have to be handled in its realization.     

Considering social ergonomics: the effects of HIT on interpersonal relationships between patients and clinicians

This study explored physicians' interactions with EHRs to understand the qualities that contribute to patient satisfaction with their use of the technologies and patient satisfaction with physician. Video-taped observations of 100 medical consultations were used to distinguish interaction patterns between physicians and EHRs. Quantified observational methods were used to contribute to ecological validity. Ten primary care physicians and 100 patients from five clinics participated in the study. Visits were videotaped and coded using an objective coding methodology to understand how physicians interacted with electronic health records. Results indicate, a variety of EHR interaction styles may be effective in providing patient-centered care.     

The effects of exchange rate regimes on economic growth: evidence from propensity score matching estimates

This is the first study that employs the propensity score matching framework to examine the average treatment effect of exchange rate regimes on economic growth. Previous studies examining the effects of different exchange regimes on growth often apply time series or panel data techniques and provide mixed results. This study employs a variety of non-parametric matching methods to address the self-selection problem, which potentially causes a bias in the traditional linear regressions. We evaluate the average treatment effect of the floating exchange rate regime on economic growth in 164 countries. Time period of the quasi experiment starts in 1970, capturing the collapse of the Bretton Woods fixed exchange rate commitment system. Results show that the average treatment effect of floating exchange rate regimes on economic growth is statistically insignificant. Verifying the results with the Rosenbaum's bounds, our findings are strong and robust. The research states that there is no evidence that employing a floating exchange rate regime compared to a fixed one leads to a higher economic growth for the countries that use this particular policy.     

A Comparison of Workers Employed in Hazardous Jobs in Terms of Job Satisfaction,Perceived Job Risk and Stress: Turkish Jean Sandblasting Workers,Dock Workers,Factory Workers and Miners

The purpose of this study is to compare job satisfaction, perception of job risk, stress symptoms and vulnerability to stress of miners, dock workers, jean sandblasting workers and factory workers. A job satisfaction scale and stress audit scale were applied to 220 workers. Results revealed that dock and jean sandblasting workers perceived their work as more risky compared to other workers. Jean sandblasting workers also had the lowest scores on job satisfaction subscales (organisational policies, physical conditions, interpersonal relations, individual factors, autonomy and wage) and total job satisfaction. Likewise, dock workers had lower scores on job satisfaction than factory workers and miners. Analyses also showed that miners did not differ from factory workers in terms of job satisfaction and stress symptoms. Moreover, jean sandblasting workers and dock workers obtained higher scores on stress symptoms. Jean sandblasting workers were also found to be the group that had the highest level of vulnerability to stress. Perceived job risk, vulnerability to stress and stress symptoms were the most important predictors of job satisfaction.     

Does the unification of health financing affect the distribution pattern of out‐of‐pocket health expenses in Turkey?

Turkey has implemented health reforms for over a decade and has taken significant steps toward unifying health financing. This study investigated the financial burden associated with out‐of‐pocket (OOP) expenditures under universal health coverage, using national 2003–2015 household budget data from the Turkish Statistical Institute. Progress was evaluated using Kakwani–Suits indices and Lorenz concentration curves. The results indicate that overall, more than a decade after its unification, redistribution of wealth in the Turkish health financing system has benefitted the wealthy but not the poor. Both curve and index approaches (Kakwani index 2003 = ?0.50; 2015 = ?0.44) reveal an increasingly regressive pattern of OOP health expenditures. The effective use of fiscal space and good political leadership are essential for the successful continuation of reforms to combat poverty in Turkey.
