Purpose: Intergroup contact is an effective strategy to improve intergroup relationships. Although intergroup relationships have been studied extensively, the individual roles of quantity and quality of contact in relationships with cognition, emotion, and intention of behavior toward other ethnic minority groups are not fully understood. This study explores the situation via network analysis among Zhuang and Yao ethnic minorities in Southwest China.

Methods: We investigated the quantity and quality of intergroup contact and cognition, emotion, and intention of behavior among a sample of 543 Zhuang and 490 Yao ethnic group members. Data were analyzed using the R-package. Network structures were analyzed via the Qgraph package, and the accuracy and stability of the network were measured via the Bootnet package; communities were detected via the Igraph package; bridge analyses were conducted via the Networktools package; and the network difference was compared via the Network Comparison Test package.

Results: The results indicated perceived intimacy is the central node. Quantity of contact constructed a community with "perceived connection," "sense of community," "knowledge about out-group," and "perceived similarity." Meanwhile, quality of contact constructed a community with "intergroup attitude" and a "feeling thermometer." The remainder of the nodes constructed two additional communities. The network global connectivity and structure between the two ethnic groups were highly similar.

Conclusion: The study examined the quantity and quality of intergroup contact via network analysis for two ethnic minority groups. It was shown that the two groups' global network structures of intergroup contact and their effects are highly similar. Specifically, quantity and quality of contact produce different effects on intergroup relations. Quantity of contact has proximal effects, including instant cognitive and emotional response without depth cognition, while quality of contact has proximal effects that may change deep-seated cognition and subsequently improve intergroup relations.

is one of the species in the China-Vietnam Collective Fishery Zone, which has a few relevant studies. In this study, the mitochondrial genome of was determined for the first time using next-generation sequencing; the overall base components of mitogenome consisting of 17,784 bp was 32.45% for A, 25.76% for T, 15.72% for G, 26.08% for C, and its GC content was 41.8%. The mitochondrial circular genome was composed of 13 protein-coding genes, 22 transfer RNAs, 2D-loop, and 2 ribosomal RNAs. Polygenetic analysis showed that the was very close to . It can provide data reference for the analysis of genetic evolution of this species.

The Importance of Ethnicity: Developing a Measure of Minority Ethnic Value and Value-Expressive Behavior Among Chinese Ethnic Minorities.

Front Psychol 2019 19;10:2603. Epub 2019 Nov 19.

Center for Studies of Education and Psychology of Ethnic Minorities in Southwest China, Southwest University, Chongqing, China.

In this study we developed the Chinese Minority Ethnic Value Questionnaire (CMEVQ) and the Chinese Minority Ethnic Value-Expressive Behavior Questionnaire (CMEVEBQ) to assess the importance of ethnicity from the standpoint of diverse ethnic values and behavioral manifestations. Drawing on self-construal theory, social identity theory, and value theory, we conducted a review of literature, in-depth interviews, semi-structured questionnaires, and expert reviews. A total of 18 items for the CMEVQ and CMEVEBQ were developed. Data were collected from three samples of Chinese ethnic minorities (mainly college students). We generated two sets of item pools from the pilot sample ( = 438). Then we examined the dimensions and final items of the CMEVQ and CMEVEBQ using exploratory factor analysis (EFA) with sample 1 ( = 665). After that, we conducted a confirmatory factor analysis (CFA) to recheck the factor structure of two refined, mutually matched, yet independent scales obtained from Study 1 with sample 2 ( = 1309); meanwhile criterion-related, K-means cluster, -tests, and multiple regression analyses were used to test the validity of and relationship between the CMEVQ and CMEVEBQ. Results showed that the multidimensional constructs with six shared first-order factors (Minority Ethnic Consciousness, Exploration, Involvement, Alienation, Inheritance, and Mastery) demonstrated a better fit for the data and supported the conceptual framework. Both questionnaires demonstrated adequate internal consistency reliability, convergent and discriminant validity, and ecological validity. That is, as practical, psychometrically sound measures, the CMEVQ and CMEVEBQ can be used to measure the importance of ethnicity for Chinese ethnic minorities. They also extend the content and sample fields of value research.

Health risk assessment of arsenic in Realgar and NiuHuangJieDu Tablets based on pharmacokinetic study.

J Trace Elem Med Biol 2018 Jul 14;48:81-86. Epub 2018 Mar 14.

NiuHuangJieDu Tablets (NHJDT), a popular realgar (AsS) containing patented traditional Chinese medicine (TCM), is widely used in the treatment of acute tonsillitis, pharyngitis, periodontitis and mouth ulcer. However, arsenic is considered as one of the most toxic elements, leading to growing concerns about the quality and safety of realgar-containing TCMs recently. In this study, health risk assessment of arsenic in realgar and NHJDT was conducted through oral administration of both substances to rats with single and multiple doses, respectively. The total blood arsenic concentration was used as the health risk indicator and determined by hydride generation-atomic fluorescence spectrometry after modified Kjeldahl digestion, and then applied to the pharmacokinetic study. For single oral dose study in rats, the low, medium, and high doses of realgar and NHJDT were set equivalent to 1, 5 and 20 times the human therapeutic dose (1.3 mg realgar/kg), respectively. Multiple doses were given at low and high dose levels every 12 h for seven consecutive days, respectively. Significant differences in the total blood arsenic pharmacokinetic profiles were observed between the corresponding realgar and NHJDT groups. These results indicated that NHJDT significantly reduced the total blood arsenic exposure present in realgar, and the detoxification mechanism might be attributed to herb-herb interactions in NHJDT. However, the accumulation of blood total arsenic was significant due to the long elimination half-life and high accumulation index in both realgar and NHJDT groups. Therefore, the potential health risk of arsenic caused by the administration of realgar-containing TCMs should be taken into account for excessive or long-term medication. Precautions should be taken for the clinical application of realgar-containing TCMs.
