Xi Jinping’s Diplomatic Philosophy and Vision for International Order: Continuity and Change from the Hu Jintao Era

This article compares the diplomatic philosophy and vision for international order held by Xi Jinping and that of his predecessor, Hu Jintao. It focuses on foreign policy initiatives, including the Belt and Road Initiative, to explore how Xi sees the world, what his diplomatic agenda is, how he has contextualized this agenda, and what policies he has developed to achieve it. It also discusses the ways in which Xi has maintained the direction of his predecessor, Hu Jintao, and the ways in which he has altered it. The article concludes with an examination of how Xi’s vision for international order differs from the existing international system.     

Gender-related Risk and Protective Factors for Depressive Symptoms and Disordered Eating in Adolescence: A 4-year Longitudinal Study

The interplay between intrapersonal risk (low self-esteem, perfectionism and body dissatisfaction) and interpersonal protection (social support) appears relevant for delineating gender-specific pathways that lead to both depressive and eating psychopathology. The aims of this longitudinal study were to examine gender differences in the levels of depressive symptoms, disordered eating and the co-occurrence of both problems from preadolescence to mid-adolescence and to identify gender-specific risk and protective factors of depressive symptoms and disordered eating. A Spanish community-based sample initially comprising 942 early adolescents (49% females) was assessed at baseline (T1; X _age = 10.8 years) and at 2 and 4-year follow-up (T2 and T3). Gender differences emerged at T2 for disordered eating and at T3 for depressive symptoms and for co-occurring depressive symptoms and disordered eating. Predictors of depressive symptoms were body dissatisfaction, low self-esteem and fear of getting fat, for girls, and body dissatisfaction and low self-esteem, for boys. Predictors of disordered eating were body dissatisfaction, depressive symptoms, BMI and perfectionism, for girls, and low social support and BMI, for boys. In addition, for boys only, social support moderated the effect of body dissatisfaction on depressive symptoms and the effect of depressive symptoms on disordered eating. The hypotheses of the study were partially supported. Clinical implications are derived regarding the components that should be included in programs for preventing depression and eating disorders in both girls and boys.     

Friendship Dynamics of Adolescent Aggression,Prosocial Behavior,and Social Status: The Moderating Role of Gender

Interactions with friends are a salient part of adolescents’ experience at school. Adolescents tend to form friendships with similar peers and, in turn, their friends influence adolescents’ behaviors and beliefs. The current study investigated early adolescents’ selection of friends and friends’ influence with regard to physical aggression, prosocial behavior, and popularity and social preference (i.e., likeability) among fifth and sixth graders (N?=?736, 52% girls at wave1, N?=?677, 52% girls at wave 2) in elementary schools in South Korea. The moderating role of gender on early adolescents’ friend selection and influence was also examined. With longitudinal social network analysis (RSiena), we found that youth tended to select friends with similar levels of physical aggression and popularity, and their friends influenced their own physical aggression and popularity over time. The higher youth were in social preference, the less likely they chose physically aggressive peers as friends. Boys were more likely to select highly popular peers as friends compared to girls, and influence effects for physical aggression and popularity were stronger for boys compared to girls. The results underscore the importance of gender in friendship dynamics among Asian early adolescents.     

Sex differences in patterns of self-disclosure among adolescents: A developmental perspective

The purpose of this study is to explore relationships among sex, target, and aspects of adolescent self-disclosure. An adaptation of the Journal and Lasakow (1958) Self-Disclosure Questionnaire (SDQ) was administered to 97 secondary school volunteers with same-sex friend and opposite-sex friend as specified targets. SDQ scores were obtained for a stratified random sample of 30 Ss matched with volunteers for school, grade, age, and sex. Results indicated no sex differences in total disclosure; Ss disclosed differentially to same-sex and opposite-sex friend. Female same-sex disclosure was greater than male same-sex disclosure. A high disclosure cluster for females was Tastes and Interests and Personality; for males it was Tastes and Interests, Work (Studies), and Attitudes and Opinions. These findings reflect patterns for volunteers and nonvolunteers, suggesting that volunteering was not a factor in obtained outcomes. Sex differences in aspects of disclosure are discussed in terms of sex-role variations in establishment of ego identity.The larger study from which the data under discussion were drawn is entitled Cognitive Self-Modeling, Conventional Group Counselling and Change in Interpersonal Communication Skills. Two co-investigators were involved in the study—J. G. Schachter and W. E. Reitz. In addition, research assistance was provided throughout the study by K. H. Hough.

Forensic evaluation and haplotypes of 19 Y-chromosomal STR loci in Koreans

In this study, 19 Y-specific STR loci (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS385, DYS388, DYS434, DYS435, DYS436, DYS437, DYS438, DYS439, DYS446, DYS449, and DYS464) were analyzed in 301 unrelated Korean males by three multiplex PCR systems. The haplotype diversity using the classical set of Y-STRs (DYS19, DYS389I/II, DYS390, DYS391, DYS392, DYS393, and DYS385; multiplex I) was 0.9963. For the same individuals, the haplotype diversity value using the new set of highly informative Y-STRs (DYS385, DYS446, DYS449, and DYS464; multiplex III) was 0.9989, while that using the combined set of Y-STRs by adding DYS388 to the previously studied DYS434, DYS435, DYS436, DYS437, DYS438, and DYS439 (multiplex II) was 0.9509. A total of 297 different haplotypes were identified using the 19 Y-STR markers, of which 293 were unique and 4 were found twice. The overall haplotype diversity was 0.9999. The evaluation of the information of selected markers by combination of each marker with the minimal haplotype showed that DYS434, DYS435, DYS436, DYS437, and DYS438 do not significantly contribute to increment of haplotype diversity. However, respective conjunction of DYS464, DYS449, and DYS446 with the minimal haplotype considerably increased the haplotype diversity. Especially, DYS464 is expected to be the most useful marker that can be included in the expanded minimal haplotype. These results including the haplotype data at 19 Y-STR loci in the present study would provide useful information in forensic practice in a Korean population.     

Characterization of deletions in the DYS385 flanking region and null alleles associated with AZFc microdeletions in Koreans

Eight DYS385 allele size discrepancies and six DYS448 null types were detected among 708 Korean men when results of three in-house multiplex short tandem repeat (STR) systems were compared. The systems included both ordinary and reduced size amplicons. Sequence analysis revealed deletion mutations at two sites upstream of the DYS385 core repeats and deletion of the entire DYS448 locus. At DYS385, allele size differences were one or two repeats and were dependent on the primer set used for polymerase chain reaction (PCR) amplification. Location of the primer target sequence in a flanking region of the STR, distal or proximal to the deletion, determined allele size. Two widely used commercial kits amplify DYS385 so as to include the mutable sites. Arrangement analysis of sequence tagged sites demonstrated that the deletion patterns at DYS448 (and DYS464) were associated with arrangements of the azoospermia factor c gene (AZFc). The DYS448 deletion appears relatively frequent in Asians.     

Understanding Chinese Economy Accurately—John Wong and His China Research

How and to what extent can China be more accurately understood? Is China best understood as it is or through theories that appear to reveal its nature? John Wong is an example of the former approach, a pursuer of economic realism in the discipline of economic analysis. This paper first describes John Wong’s conceptual model of Chinese economic development, which consists of three major components: Singapore as the reference point; economic scale as the first adjusted variable; and economic development phase as the second variable. The paper further explores sources of his choice of methodology through the positionality of his research. He cannot be neatly categorized in any existing school of economic analysis of the Western academic tradition but pursues his accurate understanding of China through pragmatism; his institutionalized research position constitutes the methodological foundation for his research strategy and conceptual framework.
