This study examines the authoritarian conditioning of political expression on social media in three Chinese societiesby analyzing three parallel surveys comprising 6942 respondents from mainland China, Hong Kong, and Taiwan. Results demonstrate that the use of social media to gather political information triggers politically expressive use of social media and indirectly predicts offline non-institutionalized political participation. Individuals' authoritarian orientation, however, moderates such indirect effects. Only people who demonstrate low or moderate adherence to authoritarian value systems exemplify this mediation model. Those with high levels of authoritarian orientation are not exemplary. Furthermore, the extent to which social media use interacts with authoritarian orientation to build a relationship with political participation presents two different patterns across three Chinese societies. The moderated mediating effect described here exists in Hong Kong and Taiwan but not in mainland China. Finally, we discuss the implications of these findings.

Researchers who use surveys or long questionnaires assume that response sets are constant over time. Three studies of Hispanics & non-Hispanics being classified in US Navy jobs (N = 219, 145, & 128) who responded to 10-point scales in long questionnaires challenge this assumption. Three response sets were measured for each section of the questionnaire: acquiescence/directionality bias, response range, & extreme checking style. Although the studies used different formats & topics, the results were quite similar. Correlations of the response set measures across adjacent time periods formed a simplex structure, suggesting that such response sets are more similar than those across distant time periods. Three hypotheses about the causes of the fluctuation of response sets are presented, & preliminary data relevant to these hypotheses are discussed. 2 Tables, 1 Figure, 12 References. Modified AA

We have derived the analytical kernels of the pricing formulae of the
CEV knockout options with time-dependent parameters for a parametric class of moving
barriers. By a series of similarity transformations and changing variables, we are
able to reduce the pricing equation to one which is reducible to the Bessel equation
with constant parameters. These results enable us to develop a simple and efficient
method for computing accurate estimates of the CEV single-barrier option prices as
well as their upper and lower bounds when the model parameters are time-dependent.
By means of the multistage approximation scheme, the upper and lower bounds for
the exact barrier option prices can be efficiently improved in a systematic manner. It
is also natural that this new approach can be easily applied to capture the valuation
of other standard CEV options with specified moving knockout barriers. In view of
the CEV model being empirically considered to be a better candidate in equity option
pricing than the traditional Black-Scholes model, more comparative pricing and precise
risk management in equity options can be achieved by incorporating term structures
of interest rates, volatility, and dividend into the CEV option valuation model.

INTRODUCTION: The European Centre for Disease Prevention and Control is developing evidence-based guidance for voluntary screening, treatment and vaccine prevention of infectious diseases for newly arriving migrants to the European Union/European Economic Area. The objective of this systematic review protocol is to guide the identification, appraisal and synthesis of the best available evidence on prevention and assessment of the following priority infectious diseases: tuberculosis, HIV, hepatitis B, hepatitis C, measles, mumps, rubella, diphtheria, tetanus, pertussis, poliomyelitis (polio), Haemophilus influenza disease, strongyloidiasis and schistosomiasis. METHODS AND ANALYSIS: The search strategy will identify evidence from existing systematic reviews and then update the effectiveness and cost-effectiveness evidence using prospective trials, economic evaluations and/or recently published systematic reviews. Interdisciplinary teams have designed logic models to help define study inclusion and exclusion criteria, guiding the search strategy and identifying relevant outcomes. We will assess the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. ETHICS AND DISSEMINATION: There are no ethical or safety issues. We anticipate disseminating the findings through open-access publications, conference abstracts and presentations. We plan to publish technical syntheses as GRADEpro evidence summaries and the systematic reviews as part of a special edition open-access publication on refugee health. We are following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols reporting guideline. This protocol is registered in PROSPERO: CRD42016045798.

Migration to the European Union (EU)/European Economic Area (EEA) affects the epidemiology of infectious diseases, including tuberculosis (TB), HIV, hepatitis B/C, and parasitic diseases. Some sub-populations of migrants are also considered to be an under-immunised group and thus at risk of vaccine-preventable diseases. Providing high-risk migrants access to timely and efficacious screening and vaccination, and understanding how best to implement more integrated screening and vaccination programmes into European health systems ensuring linkage to care and treatment, is key to improving the health of migrants and their communities, alongside meeting national and regional targets for infection surveillance, control, and elimination. The European Centre for Disease Prevention and Control (ECDC) has responded to calls to action to improve migrant health and strengthen universal health coverage by developing evidence-based guidance for policy makers, public health experts, and front-line healthcare professionals on how to approach screening and vaccination in newly arrived migrants within the EU/EEA. In this Commentary, we provide a perspective towards developing efficacious screening and vaccination of newly arrived migrants, with a focus on defining implementation challenges and evidence gaps in high-migrant receiving EU/EEA countries. There is a need now to leverage the increasing momentum around migrant health to both strengthen the evidence-base and to advocate for universal access to health care for all migrants in the EU/EEA, including undocumented migrants. This should include voluntary, confidential, and non-stigmatising screening and vaccination that should be free of charge and facilitate linkage to appropriate care and treatment.

The dataset deals with the air quality perceived by citizens before and during the enforcement of COVID-19 restrictions in ten countries around the world: Australia, Brazil, China, Ghana, India, Iran, Italy, Norway, South Africa and the United States. An online survey conveniently translated into Chinese, English, Italian, Norwegian, Persian, Portuguese collected information regarding the perceived quality of air pollution according to a Likert scale. The questionnaire was distributed between 11-05-2020 and 31-05-2020 and 9 394 respondents took part. Both the survey and the dataset (stored in a Microsoft Excel Worksheet) are available in a public repository. The collected data offer the people's subjective perspectives related to the objective improvement in air quality occurred during the COVID-19 restrictions. Furthermore, the dataset can be used for research studies involving the reduction in air pollution as experienced, to a different extent, by populations of all the ten countries.

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands.
