Effects of Linguistic Distance on Second Language Brain Activations in Bilinguals: An Exploratory Coordinate-Based Meta-Analysis

In this quantitative meta-analysis, we used the activation likelihood estimation (ALE) approach to address the effects of linguistic distance between first (L1) and second (L2) languages on language-related brain activations. In particular, we investigated how L2-related networks may change in response to linguistic distance from L1. Thus, we examined L2 brain activations in two groups of participants with English as L2 and either (i) a European language (European group, n = 13 studies) or (ii) Chinese (Chinese group, n = 18 studies) as L1. We further explored the modulatory effect of age of appropriation (AoA) and proficiency of L2. We found that, irrespective of L1-L2 distance—and to an extent—irrespective of L2 proficiency, L2 recruits brain areas supporting higher-order cognitive functions (e.g., cognitive control), although with group-specific differences (e.g., the insula region in the European group and the frontal cortex in the Chinese group). The Chinese group also selectively activated the parietal lobe, but this did not occur in the subgroup with high L2 proficiency. These preliminary results highlight the relevance of linguistic distance and call for future research to generalize findings to other language pairs and shed further light on the interaction between linguistic distance, AoA, and proficiency of L2.

Phylogeographic Relationships among Bombyx mandarina (Lepidoptera: Bombycidae) Populations and Their Relationships to B. mori Inferred from Mitochondrial Genomes

We report 37 mitochondrial genome (mitogenome) sequences of Bombyx mori strains (Lepidoptera: Bombycidae) and four of B. mandarina individuals, each preserved and collected, respectively, in South Korea. These mitogenome sequences combined with 45 public data showed a substantial genetic reduction in B. mori strains compared to the presumed ancestor B. mandarina, with the highest diversity detected in the Chinese origin B. mori. Chinese B. mandarina were divided into northern and southern groups, concordant to the Qinling–Huaihe line, and the northern group was placed as an immediate progenitor of monophyletic B. mori strains in phylogenetic analyses, as has previously been detected. However, one individual that was in close proximity to the south Qinling–Huaihe line was exceptional, belonging to the northern group. The enigmatic South Korean population of B. mandarina, which has often been regarded as a closer genetic group to Japan, was most similar to the northern Chinese group, evidencing substantial gene flow between the two regions. Although a substantial genetic divergence is present between B. mandarina in southern China and Japan, a highly supported sister relationship between the two regional populations may suggest the potential origin of Japanese B. mandarina from southern China instead of the Korean peninsula.

Investigation Into Motivation Types of Saudi and Chines EFL Learners and Gender Role Differences

This study investigates motivation types of Saudi and Chines EFL learners and gender role differences. I selected these two groups because they constituted the most dominant groups that study English abroad. The descriptive and correlational approaches were used to examine the participants’ motivation by collecting the data through questionnaire and interviews. Twenty-five Saudi and Chinese college level English language students were selected as samples for collecting data for answering the research questions. The findings showed that both groups have extrinsic and intrinsic motivation as well integrative and instrumental motivation. The Chinese group’s intrinsic motivation is stronger than the extrinsic motivation. 

Ramadan Fasting Leads to Shifts in Human Gut Microbiota Structured by Dietary Composition

The structure and diversity of human gut microbiota are directly related to diet, though less is known about the influences of ethnicity and diet-related behaviors, such as fasting (intermittent caloric restriction). In this study, we investigated whether fasting for Ramadan altered the microbiota in Chinese and Pakistani individuals. Using high-throughput 16S rRNA gene sequencing and self-reported dietary intake surveys, we determined that both the microbiota and dietary composition were significantly different with little overlap between ethnic groups. Principal Coordinate Analyses (PCoA) comparison of samples collected from both groups before and after fasting showed partial separation of microbiota related to fasting in the Pakistani group, but not in the Chinese group. Measurement of alpha diversity showed that Ramadan fasting significantly altered the coverage and ACE indices among Chinese subjects, but otherwise incurred no changes among either group. Specifically, Prevotella and Faecalibacterium drove predominance of Bacteroidetes and Firmicutes in the Pakistani group, while Bacteroides (phylum Bacteroidetes) were the most prevalent among Chinese participants both before and after fasting. We observed significant enrichment of some specific taxa and depletion of others in individuals of both populations, suggesting that fasting could affect beta diversity. Notably, Dorea, Klebsiella, and Faecalibacterium were more abundant in the Chinese group after fasting, while Sutterella, Parabacteroides, and Alistipes were significantly enriched after fasting in the Pakistani group. Evaluation of the combined groups showed that genera Coprococcus, Clostridium_XlV, and Lachnospiracea were all significantly decreased after fasting. Analysis of food intake and macronutrient energy sources showed that fat-derived energy was positively associated with Oscillibacter and Prevotella, but negatively associated with Bacteroides. In addition, the consumption of sweets was significantly positively correlated with the prevalence of Akkermansia. Our study indicated that diet was the most significant influence on microbiota, and correlated with ethnic groups, while fasting led to enrichment of specific bacterial taxa in some individuals. Given the dearth of understanding about the impacts of fasting on microbiota, our results provide valuable inroads for future study aimed at novel, personalized, behavior-based treatments targeting specific gut microbes for prevention or treatment of digestive disorders.

More than carrots and sticks: Economic statecraft and coercion in China–Taiwan relations from 2000 to 2019

China has become one of the most important trading partners for many Asian countries, and Taiwan is at the forefront of China’s economic coercion. It also leads to the following empirical puzzle: When can Beijing’s economic sanctions and incentives achieve their desired outcomes? Why and how do they often fail? Given the power asymmetry between China and Taiwan, how Taiwan resists China’s coercive measures contributes significantly to theoretical development in international relations. Taiwan has responded to Chinese economic pressure by diversifying its trade with and investment in Southeast Asian and South Asian countries to lessen dependence on China. It also securitizes China–Taiwan relations by raising public awareness about over-reliance on China’s market. Taiwan is not only a target of China’s coercion, but an active actor in its own right as well. This article re-evaluates the literature on East Asian politics and economic statecraft. First, it highlights the salience of power asymmetry to the field of economic statecraft. Second, it offers a three-level analysis of when and how China exercised economic coercion and incentives towards Taiwan. Third, it examines how Taiwan addressed Beijing’s sanctions on Chinese group tourists starting in 2016. The final section discusses some conclusions that can be drawn and suggests some avenues for future research.

The influence of zero-fare tours on the host–guest understanding

PurposeThe aim of this study is to explore the host–guest relationship at a macro level, investigating the sociopsychological relationship between a destination and its markets.Design/methodology/approachThis study adopted netnography to fulfill the research purpose. Data were collected from Sina Microblog, the predominant social media platform in China, focused on bloggers responses to a fatal conflict between a tour participant and the guide during a shopping tour.FindingsBloggers' attributional discussions help to understand the nature of the host–guest relations. Responses from Chinese and Hong Kong bloggers showcased criticism toward the other community and criticism of one's own community. These were reflected in three themes: concerns with the place of conflict or the identities of the perpetrators, hospitableness or discrimination and the Chinese and Hong Kong cultures.Research limitations/implicationsThe major limitation is that the subject of this study (young bloggers) does not represent a complete cross section of the residents of China and Hong Kong. This study suggests a need for a broader theoretical perspective of the host–guest encounter. The study results have practical implications for destinations receiving Chinese group package tours.Practical implicationsThe study results have practical implications for destinations receiving Chinese group package tours.Originality/valueOn-site interaction has been the focus of previous studies of the host–guest relationship, and off-site interactions were seldom explored. This study bridges the gap and extends the discourse on the host–guest relationship to a wider temporal (by taking a post event view) and spatial (by assessing the issue off-site) scale.

The Comparison of Clinical analysis of Chinese and German Patients with Obstructive Sleep Apnea Syndrome

Objective: To compare the sex ratio, age distribution, severity of the illness, comorbidities, and the treatment of the patients with obstructive sleep apnea syndrome in China and Germany. Methods: A retrospective study of the data was conducted, and a total of 200 patients diagnosed with obstructive sleep apnea syndrome in Germany and China from March 2013 to October 2015 were analyzed. The sex ratio, age distribution, severity of the illness, comorbidities and treatment methods were analyzed. Results: There was no significant difference in the severity of disease, sex ratio, and age distribution between the patients with obstructive sleep apnea syndrome in China and Germany(P>0.05). In terms of comorbidities, the combination of moderate and severe patients in the German group, compared with the moderate and severe patients in the Chinese group, except for cerebrovascular disease, the comorbidities were less than those in the Chinese group(P<0.05), the difference was statistically significant. In terms of treatment, the patients in the German group were compared with the patients in the Chinese group with light, moderate, and severe patients. Except for the German patients who received oral appliances and surgical treatment, more patients were treated than Chinese patients(P<0.05), the difference is statistically significant. Conclusion: The two country(Germany and China) are basically the same in the diagnosis and treatment of obstructive sleep apnea syndrome, but Germany pays more attention to details and individualization in treatment.

Mistakes in gender categorization in speech production of foreigners studying Russian

The failure to determine the grammatical gender category of adjectives, ordinal numerals and possessive pronouns in the speech production of foreigners representing a monoethnic (Chinese) group of students is considered from the perspective of cognitive linguistics. The analysis of the written works and oral statements of students studying Russian as a foreign language reveals a mechanism that leads to typical mistakes in this aspect of Russian grammar. Categorization by gender of nouns occurs through cognitive mechanisms of correlation and comparison, namely: by biological gender – motivated, by formal attribute – unmotivated; categorization by gender of adjectives, possessive pronouns and ordinal numerals, as the categorization of secondary (unmotivated) features, is absent for foreign residents. Accordingly, for a foreigner, a cognizable category that does not have an ontological character becomes a difficult obstacle to overcome at the initial stage of language learning.
