Facebook use and acculturation: The case of overseas Chinese professionals in western countries

The emergence of social network sites has provided new opportunities for intercultural communication. This study is one of the first to explore the role of Facebook on the acculturation of Chinese professionals overseas. Through qualitative interviews, we explored how overseas Chinese professionals use Facebook to maintain their social networks, manage their multicultural identities, and adapt to Western culture in their host countries. Our research reveals that overseas Chinese professionals tended to manage their identity with little self-awareness, and their Facebook communication reflected Chinese traditional culture in many ways. Facebook was regarded as a useful acculturation tool for them to learn about popular social topics in the host countri

Oligorotaxane radicals under orders

A strategy for creating foldameric oligorotaxanes composed of only positively charged components is reported. Threadlike components-namely oligoviologens-in which different numbers of 4,4'-bipyridinium (BIPY(2+)) subunits are linked by p-xylylene bridges, are shown to be capable of being threaded by cyclobis(paraquat-p-phenylene) (CBPQT(4+)) rings following the introduction of radical-pairing interactions under reducing conditions. UV/vis/NIR spectroscopic and electrochemical investigations suggest that the reduced oligopseudorotaxanes fold into highly ordered secondary structures as a result of the formation of BIPY(\u2022+) radical cation pairs. Furthermore, by installing bulky stoppers at each end of the oligopseudorotaxanes by means of Cu-free alkyne-azide cycloadditions, their analogous oligorotaxanes, which retain the same stoichiometries as their progenitors, can be prepared. Solution-state studies of the oligorotaxanes indicate that their mechanically interlocked structures lead to the enforced interactions between the dumbbell and ring components, allowing them to fold (contract) in their reduced states and unfold (expand) in their fully oxidized states as a result of Coulombic repulsions. This electrochemically controlled reversible folding and unfolding process, during which the oligorotaxanes experience length contractions and expansions, is reminiscent of the mechanisms of actuation associated with muscle fibers

Homelessness coverage, social reality, and media ownership: Comparing a national newspaper with two regional newspapers in Canada

The media plays an important role in the discourse of homelessness. The purpose of this study was to compare how two Alberta newspapers (Calgary Herald and Edmonton Journal) and one national newspaper(the Globe and Mail) covered homeless issues in terms of population, main themes, article type, monthly differences, and critical time periods. Through purposive sampling technique, 449

Understanding the Chinese Hui Ethnic Minority’s Information Seeking on Cardiovascular Diseases: A Focus Group Study

The Chinese Hui ethnic minority group is an Islamic minority. The Hui people comprise the third largest minority population in China and are widely distributed throughout the country. Previous research shows that the Hui had a higher prevalence of cardiovascular risk factors (CVRFs) than most other ethnic groups. Therefore, the availability of health information relating to these factors is especially important for the Hui minority’s preventive healthcare. They do, however, experience difficulties in obtaining health-related information. The current research aims to identify the needs of the Hui people on where and how they obtain cardiovascular disease (CVD) related information from the media and other sources. Six focus groups were conducted in Shenyang City. The results revealed that the participants relied on different sources to get advice about CVDs, of which the internet and television were the most prominent ones. The participants expressed a desire for credible and professional information from different sources and asked for mediated health communication programs specifically targeted at the Hui. In addition, the participants felt ignored by the Chinese mainstream media at large, which created barriers for them to get health information

Chinese Urban Hui Muslims’ Access to and Evaluation of Cardiovascular Diseases-Related Health Information from Different Sources

Abstract: This research aims to identify the sources that urban Hui Muslims access to get health information related to cardiovascular diseases (CVD) and how they evaluate the information from different sources. This paper focuses on health information related to cardiovascular diseases among Hui Muslims. The data was gathered by means of an online survey administered on mobile devices. To put the answers given by Hui Muslims into perspective and make a comparison between Hui Muslims and the Han people, we also gathered information from Han—the dominant group in China. The results showed that Chinese Hui Muslims mostly used mediated sources, while Han people mainly used interpersonal sources. Both Hui Muslims and Han people trusted and preferred health information about cardiovascular diseases provided by health organizations, doctors, and healthcare providers. The information given by religious leaders was trusted the least, although Hui Muslims were significantly more positive about religious authority than the Han people. The current results are relevant for Chinese health information promoters and can help them diffuse CVD health information more effectively to urban Hui Muslims

A fluorescence-switchable luminogen in the solid state: a sensitive and selective sensor for the fast "turn-on" detection of primary amine gas

The emission of pyrrole-substituted benzoic acid can be repeatedly switched between the dark and bright states in the solid state by chemical fuming and heating processes, enabling it to work as a rapid sensitive fluorescent sensor for primary amine detection

Homelessness Coverage in Major Canadian Newspapers, 1987 – 2007

This article describes how the Canadian printed news media depicted the homeless and their situations between 1987 and 2007. Our study used a descriptive, cross-sectional design and a content analysis was conducted on selected newspaper articles on homelessness issues. The main themes were housing-related issues, profiling of homelessness, health-related issues, economic factors, illegal activities, community aid and support, and social factors as cause of homelessness. Housing related issues, community aid and support, profiling of homelessness and economic factors were addressed in 85.3% of the stories. This study provides a retrospective examination of the media’s interests in and portrayal of the homeless and homelessness issues

Anisotropic, Intermediate Coupling Superconductivity in Cu0.03TaS2

The anisotropic superconducting state properties in Cu0.03TaS2 have been investigated by magnetization, magnetoresistance, and specific heat measurements. It clearly shows that Cu0.03TaS2 undergoes a superconducting transition at TC = 4.03 K. The obtained superconducting parameters demonstrate that Cu0.03TaS2 is an anisotropic type-II superconductor. Combining specific heat jump = 1.6(4), gap ratio 2/kBTC = 4.0(9) and the estimated electron-phonon coupling constant ~ 0.68, the superconductivity in Cu0.03TaS2 is explained within the intermediate coupling BCS scenario. First-principles electronic structure calculations suggest that copper intercalation of 2H-TaS2 causes a considerable increase of the Fermi surface volume and the carrier density, which suppresses the CDW fluctuation and favors the raise of TC.Comment: 16pages, 5figure

HIV Screening and Awareness Survey for Pregnant Women in a Remote Area in Xinjiang Uyghur Autonomous Region of China

Objective: The number of people infected with human immunodeficiency virus (HIV) in China has increased in recent years. HIV screening for pregnant women was performed in a remote area in Xinjiang, as an effort to promote universal HIV screening in pregnant women and to help prevention of mother-to-child transmission. Methods: Pregnant women in Burqin and Jeminay Counties in Xinjiang were offered free voluntary HIV screening. Local mid-level medical workers were trained to use Determine® HIV-1/2 kit for HIV screening. All the tested pregnant women signed a consent form, received HIV education material, and participated in an HIV knowledge survey. Results: All the 890 pregnant women receiving HIV test had negative result. Among these women, 67.6% were Kazakh and 40.9% were farmers. Survey of HIV knowledge showed that these women's awareness about mother-to-child transmission was limited. The levels of HIV knowledge were related with ethnic background, age, education and profession of the pregnant women. Conclusion: The results suggested that HIV infection had not become a significant problem among the pregnant women in this remote area of Xinjiang, but continued efforts to improve the awareness of HIV, especially the knowledge about mother-to-child transmission of HIV, in pregnant women were needed

Comparison of Population-Based Association Study Methods Correcting for Population Stratification

Population stratification can cause spurious associations in population–based association studies. Several statistical methods have been proposed to reduce the impact of population stratification on population–based association studies. We simulated a set of stratified populations based on the real haplotype data from the HapMap ENCODE project, and compared the relative power, type I error rates, accuracy and positive prediction value of four prevailing population–based association study methods: traditional case-control tests, structured association (SA), genomic control (GC) and principal components analysis (PCA) under various population stratification levels. Additionally, we evaluated the effects of sample sizes and frequencies of disease susceptible allele on the performance of the four analytical methods in the presence of population stratification. We found that the performance of PCA was very stable under various scenarios. Our comparison results suggest that SA and PCA have comparable performance, if sufficient ancestral informative markers are used in SA analysis. GC appeared to be strongly conservative in significantly stratified populations. It may be better to apply GC in the stratified populations with low stratification level. Our study intends to provide a practical guideline for researchers to select proper study methods and make appropriate inference of the results in population-based association studies
