A Monte Carlo simulation study on partially adaptive estimators of linear regression models

This paper presents a comprehensive comparison of well-known partially adaptive estimators (PAEs) in terms of efficiency in estimating regression parameters. The aim is to identify the best estimators of regression parameters when error terms follow from normal, Laplace, Student's t, normal mixture, lognormal and gamma distribution via the Monte Carlo simulation. In the results of the simulation, efficient PAEs are determined in the case of symmetric leptokurtic and skewed leptokurtic regression error data. Additionally, these estimators are also compared in terms of regression applications. Regarding these applications, using certain standard error estimators, it is shown that PAEs can reduce the standard error of the slope parameter estimate relative to ordinary least squares.     

Tracking public relations history in 1960s’ Turkey: The prevalence and reflections of development discourse

This study is based on a historical research, which focuses on the institutionalization of public relations in Turkey during the 1960s, and interprets this process in the frame of planned development discourse. Primary written sources collected from archive research and oral narratives generated from fourteen semi-structured interviews conducted with the pioneers in Turkey are analyzed through categorization and thematization. Findings of the historical research indicated that similar themes and orientations guided public relations practices in public and private sector in this period. Accordingly public relations education provided necessary intellectual background and human resources.     

Mediator role of intergroup anxiety in relationship between the social contact,intercultural sensitivity and attitudes towards Syrians among Turkish local society

Turkey is the country with the highest Syrian refugee population hosted in the world. Social acceptance of immigrants by the local community is as important as the social cohesion of immigrants regarding the social integration process. The aim of the current study was to examine the role of social contact, intercultural sensitivity, intergroup anxiety, gender, age, education, abroad experience and city on attitudes of Turkish local society towards Syrians. In this regard, data were collected from 207 local community members living in Ankara and Adana provinces of Turkey. According to the analysis, qualitative social contact, intercultural sensitivity and intergroup anxiety predicted the attitudes of the local community towards Syrians. In addition, intergroup anxiety had a mediating role between qualitative social contact, intercultural sensitivity and attitudes towards Syrians. When close social contact and intercultural sensitivity of Turkish local society increase, intergroup anxiety decreases and it increases positive attitudes towards Syrians. Lastly, while there was no gender difference in attitude towards Syrians, females were higher in intercultural sensitivity than males.     

Studying Modern Nation‐State in a World‐Historical Perspective: The Instance of Iraq

By examining conceptual and historical approaches on modern state and state formation in the context of Iraq, this paper addresses four interrelated methodological aspects of studying state formation (1) to contest the simplicity of Eurocentric knowledge production in studying state formation especially in the periphery, (2) to bring capital and nation‐state into a relational analysis and to call for research on how they constitute each other historically and geographically, (3) to integrate methodologically local and world‐historical context in understanding the historical complexity of state formation, (4) to problematize the concepts of “capital relation” in order to recognize nature and transformation of nature in the study of state formation.     

MARS as an alternative approach of Gaussian graphical model for biochemical networks

The Gaussian graphical model (GGM) is one of the well-known modelling approaches to describe biological networks under the steady-state condition via the precision matrix of data. In literature there are different methods to infer model parameters based on GGM. The neighbourhood selection with the lasso regression and the graphical lasso method are the most common techniques among these alternative estimation methods. But they can be computationally demanding when the system's dimension increases. Here, we suggest a non-parametric statistical approach, called the multivariate adaptive regression splines (MARS) as an alternative of GGM. To compare the performance of both models, we evaluate the findings of normal and non-normal data via the specificity, precision, F-measures and their computational costs. From the outputs, we see that MARS performs well, resulting in, a plausible alternative approach with respect to GGM in the construction of complex biological systems.

Towards a ‘Harmonious Society’? a brief case study of the post-Liberation settlement in Beijing of Uyghur intellectuals and their relations with the majority society

Currently, the construction of a ‘Harmonious Society’ is an important yet challenging official project in the People's Republic of China. Under Chinese Communist Party supervision, the government has undertaken some measures to achieve this goal. In the country's capital, Beijing, the majority society (‘social majority’) is composed of peoples considered to be Han Chinese (), but the population there also includes representatives from 55 recognised minority society groups (). Many such latter groups, especially Uyghurs and Tibetans, have long maintained distinctive cultural traditions, practices, languages, and ‘memories’ from those of the majority society – and are ‘different’ in physical appearance, customary dress and other features. Officially, however, all are ‘Chinese citizens’ (). Recently, some negative and disharmonious trends have appeared in majority-minority relations. Based on academic fieldwork research, this essay focuses on ‘Uyghur intellectuals’ in Beijing, analytically discussing their relationships with the majority society there, identifying issues and problems in those relationships, and offering informed, constructive suggestions to achieve a more ‘Harmonious Society’ in China.     

Recantation of Sexual Abuse Disclosure Among Child Victims: Accommodation Syndrome

Background: Disclosing the sexual abuse may be related on many individual and/or environmental factors in all age groups. The sociocultural context is the most influential factor of the disclosing process especially for those living in patriarchal cultural values. This study compares the impacts of sexual abuse and other sociodemographic variables between recanting and non-recanting victimized groups in Adana city from Turkey.

Methods: The samples attending our department were divided into two groups: group 1 comprised victims who recanted their first abuse disclosure, and group 2 comprised victims who insisted on the veracity of their first report at further evaluations. The characteristics of the child, family, and abuser were compared between recanting victims and non-recanting victims by retrospective data.

Results: Each group included 27 children, for a total of 54 subjects. All adverse social reactions after the sexual abuse, including keeping secrets and a repressive family attitude, were higher among group 1 victims than group 2 victims (p < 0.0001).

Conclusions: Although they are victimized by protecting family integrity, victims may show a tendency to keep secrets and to not immediately disclose an abuse event.
