In this qualitative study, we investigated the social class worldviews of Chinese International Students (CIS) in the United States. Social class worldviews are a constellation of beliefs, attitudes, and values that individuals use to maintain a sense of psychological equilibrium within their perceived social class groups and culture. Having interviewed eleven CIS in a midwestern city in the United States, the researchers found that their experiences reflected five themes: (1) social class consciousness; (2) social class socialization; (3) social class resources; (4) social class values; and (5) social class challenges. Suggestions for research and implications for higher education are discussed

Background Study: The effects of the flipped classroom (FC) on students' academic performance remain ambiguous, and the use of pre-class videos may be one of the main factors hindering students' progress. A software package called GeoGebra has been proposed as a substitute for pre-class videos to aid students' learning. Objective: This study investigates the effect of the FC using GeoGebra (FCG) on mathematical performance and memory among senior secondary students. Methods: One hundred and sixty students of a senior high school in China were selected. A quasi-experimental design was implemented in which the classes were split into the intervention group (FCG), control group A (FCV) and control group B (TL) by random assignment. Pretest, Post-test 1 and Post-test 2 were introduced. Results and Conclusion: The results indicate that both the FCG and the FC with pre-class videos (FCV) were more effective than traditional lectures in enhancing students' academic test scores, and that the effect of the FCG was comparable to its video counterpart, F(2, 136) = 3.752, [rho] = 0.026, [eta][superscript 2] = 0.052. Although their effects were similar, the qualitative results revealed some hidden benefits associated with the replacement of pre-class video with GeoGebra. Furthermore, although they were equally effective in promoting students' performance in the short-term, the long-term effects on academic performance of both forms of FC were non-significant when compared with traditional lectures.

This study consisted of two stages. In stage A, 38 students were divided randomly into an experimental and a control group. The experimental group received lectures assisted by dynamic geometry software (DGS) and the control group received lectures using chalk and blackboard. The effects of DGS on metacognition and its components were quantitatively assessed. In stage B, follow-up interviews were carried out to understand the mechanism by which DGS improves metacognition. The results reveal that metacognition, especially for prediction and planning, can be significantly improved by using GeoGebra instead of the traditional lecture format. The findings suggest that visualization, dragging, dynamic platforms and immediate feedback are the four main factors underlying such developments.

Background: It remains unknown whether good neighbourhood perception can enhance the benefits of favourable built environment to physical activity. Moreover, the moderation pattern is less understood in developing countries. Objectives: This work aims to examine the moderation effects of perceived neighbourhood safety and aesthetics on the relationship between built environment and time for recreational walking. Methods: We performed the examination using a sample of 760 residents in Fuzhou City, China. The Negative Binomial Regression Model was developed to examine the moderation roles of neighbourhood safety and aesthetics on the impact of built environment, adjusting for the effects of location, socioeconomic, personal preferences and social environment factors. Moreover, two sensitivity analyses were performed to test whether the moderators found are robust to the control of residential self-selection, and differential measures of conceptually-comparable aspects of built environment. Results: We found stronger associations of time for recreational walking with road density and proportion of parks and squares POIs for residents with high perception of neighbourhood safety, compared to those with low perception of neighbourhood safety. There was a greater effect of the proportion of parks and squares POIs, when perceived aesthetics was high than when perceived aesthetics was low. The findings of neighbourhood safety and aesthetics as moderator, were robust in the two sensitivity analyses. No significant moderation effect was found for land use diversity. Conclusions: High perceived neighbourhood safety can magnify the positive effects of road connectivity and accessibility to parks and squares. Neighbourhood aesthetics positively moderates the association of time for recreational walking with accessibility to parks and squares. The findings emphasize the need to consider safety- and aesthetics-specific differences in estimates of built environment effects. Improvements in neighbourhood safety and aesthetics are key to effective interventions in built environment to better promote physical activity. [ABSTRACT FROM AUTHOR]

Lay Description: What is already known about this topic: Flipped classroom is an effective strategy in teaching mathematics.Among those challenges, video may be one of the main factors hindering the effect of flipped classroom. What this paper adds: GeoGebra could be an effective alternative to video.Effect between the flipped classroom using GeoGebra and the flipped classroom using video were similar.Both the flipped classroom with GeoGebra and the flipped classroom with videos were more effective than traditional lectures. Implications for practice and/or policy: Students' short‐term performance could be enhanced by visualisation provided by flipped classroom.To enhance students' long‐term performance, an appropriate amount of homework is suggested.

Background: Climate change has shifted and will continue to alter the patterns of daytime and nighttime temperatures. However, it remains unclear whether hot days and nights, as well as cold days and nights, have varying impacts on mental disorders. Methods: Daily hospital-based data on 1.2 million outpatient visits for mental disorders were obtained from 15 Chinese cities (2011-2015). The index of hot day excess, hot night excess, cold day excess, and cold night excess were used to measure the intensity of hot/cold days and nights. Firstly, a distributed lag non-linear model was used to estimate the risk of mental disorders associated with hot/cold days and nights for each city. Secondly, city-specific estimates were pooled by multivariate meta-analysis to obtain national effect estimates. Thirdly, the attributable fraction of mental disorders was estimated for the nation, genders, age groups, heating methods, and air conditioning penetration rates. Results: Our findings revealed that both hot and cold nights were associated with a higher risk of mental disorders compared to hot and cold days. The attributable fraction of mental disorders was higher for cold (night: 25.74%; day: 19.65%) in contrast to heat (night: 16.91%; day: 7.24%). Males, the elderly, cities using central heating, and cities with low air conditioning penetration rates were vulnerable to cold nights. Conclusions: This nationwide study highlights the adverse effects and significant burden of hot and cold nights on mental disorders. It underscores the potential for mitigating these impacts through the adoption of air conditioning, particularly in southern cities across China. [ABSTRACT FROM AUTHOR]

Air pollution remains a major threat to cardiovascular health and most acute myocardial infarction (AMI) deaths occur at home. However, currently established knowledge on the deleterious effect of air pollution on AMI has been limited to routinely monitored air pollutants and overlooked the place of death. In this study, we examined the association between short-term residential exposure to China's routinely monitored and unmonitored air pollutants and the risk of AMI deaths at home. A time-stratified case-crossover analysis was undertaken to associate short-term residential exposure to air pollution with 0.1 million AMI deaths at home in Jiangsu Province (China) during 2016–2019. Individual-level residential exposure to five unmonitored and monitored air pollutants including PM1 (particulate matter with an aerodynamic diameter ≤ 1 μm) and PM2.5 (particulate matter with an aerodynamic diameter ≤ 2.5 μm), SO2 (sulfur dioxide), NO2 (nitrogen dioxide), and O3 (ozone) was estimated from satellite remote sensing and machine learning technique. We found that exposure to five air pollutants, even below the recently released stricter air quality standards of the World Health Organization (WHO), was all associated with increased odds of AMI deaths at home. The odds of AMI deaths increased by 20% (95% confidence interval: 8 to 33%), 22% (12 to 33%), 14% (2 to 27%), 13% (3 to 25%), and 7% (3 to 12%) for an interquartile range increase in PM1, PM2.5, SO2, NO2, and O3, respectively. A greater magnitude of association between NO2 or O3 and AMI deaths was observed in females and in the warm season. The greatest association between PM1 and AMI deaths was found in individuals aged ≤ 64 years. This study for the first time suggests that residential exposure to routinely monitored and unmonitored air pollutants, even below the newest WHO air quality standards, is still associated with higher odds of AMI deaths at home. Future studies are warranted to understand the biological mechanisms behind the triggering of AMI deaths by air pollution exposure, to develop intervention strategies to reduce AMI deaths triggered by air pollution exposure, and to evaluate the cost-effectiveness, accessibility, and sustainability of these intervention strategies.

Results of a study of children's performance on pseudohomophone naming, similarity judgment, and lexical decision suggest that training in pinyin, a system for spelling Chinese words in Latin letters, helps child readers pronounce unfamiliar words, and makes them more responsive to visual information but less precise in word recognition.

Discussion on environmental sustainability in the past two decades has often engendered more controversy than agreement. The Beijing Olympics in 2008 and 2022 are examples of state bureaucrats and international media outlets upholding polarized viewpoints on achieving carbon neutrality. The "original ecology" folk song of 21st-century China further demonstrates how anthropocentric interests could easily divert people's attention away from issues critical to planetary wellness.

This study used the contracting projects of a district branch of the Women's Federation in Guangzhou as case examples to demonstrate both the Chinese state's contractual controls over social work organisations (SWOs) and the pragmatic response strategies of SWOs and professionals. Semi-structured interviews were conducted with seventeen participants, including local officials of the Women's Federation and social workers from contracted SWOs. It was found that with the ultimate goal of consolidating the legitimacy of the Communist Party of China, the Women's Federation's dual role in politics and service provision had led to normative, managerial, technical and relational controls over SWOs. SWOs and professionals were generally submissive to these controls, but they employed diverse coping strategies, including compliance, bargaining, transformation and investment in personal relationships. The interactions within the contractual relationship created a pragmatic professionalism that embraced dominant political ideologies, employed de-politicising techniques, and personally depended on individual officials.

Traditional Chinese medicine (TCM) has long been used to treat diabetes mellitus and angina. It has also gained widespread clinical applications in China as a common adjuvant treatment. Although there is high-quality evidence that TCM is effective in regulating glucose and lipid metabolism, the cardiovascular protective effect of TCM in the treatment of diabetes mellitus has not been fully elucidated, especially in patients with both diabetes mellitus and coronary heart disease (CHD). We systematically assessed the efficacy and safety of TCM for the adjuvant treatment of patients with CHD and diabetes mellitus and examined the pharmacological effects and potential mechanisms of TCM medication/herbs on diabetes mellitus with CHD. We found that TCM could improve the control effect of conventional treatment on cardiac function, hemorheology, blood glucose, blood lipid, and inflammation, thus reducing the frequency of angina and the incidence of cardiovascular events and all-cause mortality. These findings indicate that TCM may be used as a complementary approach for patients with diabetes mellitus and CHD. Nevertheless, more rigorously designed randomized controlled trials and long-term evaluations are needed to support these findings. [ABSTRACT FROM AUTHOR]

Aims: To test the effectiveness of intractive, instant messaging chat‐based mobile phone support versus text‐based mobile phone support integrated with brief interventions on self‐reported smoking abstinence in workplaces. Design A two‐arm parallel cluster‐randomized controlled trial with follow‐up to 12 months. Setting: Seventy‐five companies in Hong Kong, China. Participants: Daily cigarette adult smokers (92.0% male, 90.9% not ready to quit within the next 30 days) from 75 companies (clusters). Interventions: Participants were cluster‐randomized to receive text‐based support (TBS, n = 375; 38 clusters) or chat‐based support (CBS, n = 304; 37 clusters). TBS participants received automated and fix‐scheduled text messages on cessation advice and support. CBS participants received fix‐scheduled text messages and additional real‐time psychosocial and cessation support via instant messaging services (e.g. WhatsApp) by counsellors. Both groups received a 1‐hour health talk at baseline and brief telephone counselling at 1 week and 1, 3, 6 and 12 months. Measurements: The primary outcome was self‐reported 7‐day point‐prevalence abstinence at 6 months post‐treatment initiation. Secondary outcomes included 7‐day point‐prevalence abstinence at 12 months, repeated 7‐day point‐prevalence abstinence, smoking reduction, quit attempts and intervention engagement, defined as having read text messages and/or engaged in conversation with counsellors. Findings By intention‐to‐treat assuming that dropouts were smoking, self‐reported abstinence was not significantly different between the CBS and TBS groups at 6 months [18.8 versus 21.6%, risk ratio (RR) = 0.87, 95% confidence interval (CI) = 0.61, 1.23, retention = 71.3%] and 12 months (21.4 versus 24.0%, RR = 0.90, 95% CI = 0.66, 1.21, retention = 70.8%). The repeated 7‐day point‐prevalence abstinence, smoking reduction and quit attempts were similar between the groups. The participants who were engaged in the text‐ and/or chat‐based interventions had greater abstinence (adjusted RR = 2.91, 95% CI = 1.87, 4.52) at 6 months compared with unengaged participants. Conclusions: Compared with a text messaging mobile phone intervention, a chat‐based instant messaging mobile phone intervention did not improve smoking abstinence over 12 months in workplaces. Engagement in text‐based or chat‐based interventions was associated with higher quit rates compared with non‐engagement. [ABSTRACT FROM AUTHOR]

It remains unknown whether exposure to ambient air pollution can be a mediator linking socioeconomic indicator to health outcome. The present study aims to examine the mediation effect of PM2.5 air pollution on the association between urban–rural division and the incidence (mortality) rate of male lung cancer. We performed a nationwide analysis in 353 counties (districts) of China between 2006 and 2015. A structural equation model was developed to determine the mediation effect of exposure to PM2.5. We also tested whether the findings of the mediation effect of exposure to PM2.5 are sensitive to the controls of smoking factors and additional air pollutant, and PM2.5 exposures with different lag structures. According to the results, we found that exposure to PM2.5 significantly mediated the association between urban–rural division and the incidence rate of male lung cancer. Specifically, there were significant associations between urban–rural division, exposure to PM2.5, and the incidence rate of male lung cancer, with PM2.5 exposure accounting for 29.80% of total urban–rural difference in incidence rates of male lung cancer. A similar pattern of results was observed for the mortality rate of male lung cancer. That is, there was a significant mediation effect by PM2.5 on the association of the mortality rate with urban–rural division. The findings of exposure to PM2.5 as a mediator were robust in the three sensitivity analyses. In conclusion, urban–rural difference in exposures to PM2.5 may be a potential factor that contributes to urban–rural disparity in male lung cancer diseases in China. The findings inform that air pollution management and control may be effective measures to alleviate the great difference in male lung cancer diseases between urban and rural areas in China.

China's practice of contracting out social services raises two related questions. The first one seeks to determine "the contractual relationship" between the Chinese government and its third sector in a mixed welfare regime. The second one inquires whether China's commissioning welfare strategy has increased the power of its civil society. This study attempts to address these two issues based on the experiences of non‐governmental organisations (NGOs) in a Chinese city. It was found that the contracted NGOs were unable to obtain an equal status but were treated as assistants of local governments. The NGOs were also asked to do extra work that was not listed in the service contracts. Moreover, the service performance assessment criteria were unable to accurately evaluate the work of NGOs. Thus, the welfare participation of Chinese NGOs has not brought with them more political power. It is proposed that China's welfare reform needs to be backed up by its legal reform to put in place a mechanism that tackles the unequal power distribution between welfare purchasers and welfare providers. The study further illustrates that the Chinese government has adopted a pragmatic instrumentalism strategy by placing NGOs in a supplementary and subordinate role. This paper offers a conceptual discourse on analysing the state‐NGOs relationship against China's market reform and its search for a better welfare management strategy. [ABSTRACT FROM AUTHOR]

In 1953, Shanghai Film Studio produced a Shaoxing opera film version of The Butterfly Lovers as the first color film of the People's Republic of China. Noted for its immense popularity in the Sinophone sphere throughout the 1950s, the film actually exemplifies a history of Shaoxing opera that is connected to urbanization and nationalism as well as women's liberation and the cultural politics of early communist China. It is an early example of how Chinese opera and modern media technology contribute to transnational negotiations and imaginations of Chinese identities. [ABSTRACT FROM AUTHOR]

Background Chlamydia trachomatis (CT) is a major cause of infertility and adverse birth outcomes, but its epidemiology among childbearing-age women remains unclear in China. This study investigated the prevalence of CT and associated factors among Chinese women aged 16–44 years who were either (1) pregnant, (2) attending gynecology clinics, or (3) subfertile. Methods We conducted a cross-sectional survey and recruited participants from obstetrics, gynecology, and infertility clinics in Guangdong between March and December 2019. We collected information on individuals' sociodemographic characteristics, previous medical conditions, and sexual behaviors. First-pass urine and cervical swabs were tested using nucleic acid amplification testing. We calculated the prevalence in each population and subgroup by age, education, and age at first sex. Multivariable binomial regression models were used to identify factors associated with CT. Results We recruited 881 pregnant women, 595 gynecology clinic attendees, and 254 subfertile women. The prevalence of CT was 6.7% (95% CI, 5.2%–8.5%), 8.2% (95% CI, 6.2%–10.7%), and 5.9% (95% CI, 3.5%–9.3%) for the above 3 populations, respectively. The subgroup-specific prevalence was highest among those who first had sex before age 25 years and older pregnant women (>35 years). The proportion of asymptomatic CT was 84.8%, 40.0%, and 60.0% among pregnant women, gynecology clinic attendees, and subfertile women, respectively. Age at first sex (<25 years), multipara, and ever having more than 1 partner increased the risk of CT. Conclusions Childbearing-age women in China have a high prevalence of CT. As most women with CT were asymptomatic, more optimal prevention strategies are urgently needed in China. [ABSTRACT FROM AUTHOR]

Population estimates for high-resolution spatial grid cells data can reflect detailed spatial distribution of population, which are valuable for epidemiological studies, disaster risk assessments, and public resource allocation. However, choice of source data and methods for producing gridded population data sets can introduce spatial bias, especially in regions with complex geography. We assess the performance of four gridded population data sets from 2015 for the Dian-Gui-Qian region of Southwest China: Gridded Population of the World version 4 (GPW4), Global Human Settlement (GHS), LandScan, and WorldPop. At the town-scale, we found that GHS and WorldPop most closely resembled the 2015 population data used for validation. At the intra-town scale, for which spatially disaggregated population validation data do not exist, we compared each data set against Google Earth high-resolution images and found that WorldPop most closely resembled the population distribution that could be inferred from the imagery. We conclude that in general, WorldPop performs better than GPW, GHS, and LandScan. [ABSTRACT FROM AUTHOR]

Brown carbon (BrC) is a special type of organic aerosol (OA), capable of absorbing solar radiation from near-ultraviolet (UV) to visible wavelengths, which may lead to an increased aerosol radiative effect in the atmosphere. While high concentrations of OAs have been observed in the Pearl River Delta (PRD) region of China, the optical properties and corresponding radiative forcing of BrC in the PRD are still not well understood. In this work, we conducted a set of comprehensive measurements of atmospheric particulate matter from 29 November 2014 to 2 January 2015 to investigate aerosol compositions, optical properties, source origins, and radiative forcing effects at a suburban station in Guangzhou. The particle absorption Ångström exponent (AAE) was deduced and utilized to distinguish light absorption by BrC from that by black carbon (BC). The results showed that the average absorption contributions of BrC were 34.1±8.0 % at 370 nm, 23.7±7.3 % at 470 nm, 16.0±6.7 % at 520 nm, 13.0±5.4 % at 590 nm, and 8.7±4.3 % at 660 nm. A sensitivity analysis of the evaluation of the absorption Ångström exponent of BC (AAE BC) was conducted based on the Mie theory calculation assuming that the BC-containing aerosol was mixed with the core–shell and external configurations. The corresponding uncertainty in AAE BC was acquired. We found that variations in the imaginary refractive index (RI) of the BC core can significantly affect the estimation of AAE BC. However, AAE BC was relatively less sensitive to the real part of the RI of the BC core and was least sensitive to the real part of the RI of the non-light-absorbing shell. BrC absorption was closely related to aerosol potassium cation content (K+), a common tracer of biomass burning emissions, which was most likely associated with straw burning in the rural area of the western PRD. Diurnal variation in BrC absorption revealed that primary organic aerosols had a larger BrC absorption capacity than secondary organic aerosols (SOAs). Radiative transfer simulations showed that BrC absorption may cause 2.3±1.8 W m -2 radiative forcing at the top of the atmosphere (TOA) and contribute to 15.8±4.4 % of the aerosol warming effect. A chart was constructed to conveniently assess the BrC radiative forcing efficiency in the studied area with reference to certain aerosol single-scattering albedo (SSA) and BrC absorption contributions at various wavelengths. Evidently, the BrC radiative forcing efficiency was higher at shorter wavelengths. [ABSTRACT FROM AUTHOR]

Rapid urbanization, which is closely related to economic growth, human health, and micro-climate, has resulted in a considerable amount of anthropogenic heat emissions. The lack of estimation data on long-term anthropogenic heat emissions is a great concern in climate and urban flux research. This study estimated the annual average anthropogenic heat fluxes (AHFs) in Beijing–Tianjin–Hebei region in China between 1995 and 2015 on the basis of multisource remote sensing images and ancillary data. Anthropogenic heat emissions from different sources (e.g., industries, buildings, transportation, and human metabolism) were also estimated to analyze the composition of AHFs. The spatiotemporal dynamics of long-term AHFs with high spatial resolution (500 m) were estimated by using a refined AHF model and then analyzed using trend and standard deviation ellipse analyses. Results showed that values in the region increased significantly from 0.15 W· m−2 in 1995 to 1.46 W· m−2 in 2015. Heat emissions from industries, transportation, buildings, and human metabolism accounted for 64.1%, 17.0%, 15.5%, and 3.4% of the total anthropogenic heat emissions, respectively. Industrial energy consumption was the dominant contributor to the anthropogenic heat emissions in the region. During this period, industrial heat emissions presented an unstable variation but showed a growing trend overall. Heat emissions from buildings increased steadily. Spatial distribution was extended with an increasing tendency of the difference between the maximum and the minimum and was generally dominated by the northeast–southwest directional pattern. The spatiotemporal distribution patterns and trends of AHFs could provide vital support on management decision in city planning and environmental monitoring. Image 1 • AHF increased significantly from 0.15 W· m−2 in 1995 to 1.46 W· m−2 in 2015 in BTH region. • Industrial energy consumption was the dominant contributor to AHF, accounting for about 69%. • The spatial distribution of AHF was generally dominated by the "northeast-southwest" directional pattern. The characteristics of spatiotemporal dynamics of anthropogenic heat flux are conducive for providing holistic information related to urban heat island study and vital support on management decision in city planning and environmental monitoring for policy makers.

This randomized controlled trial explored the effects of a Ving Tsun (VT) Chinese martial art training program on reactive standing balance performance, postural muscle reflex contraction latency, leg muscle performance, balance confidence and falls in community-dwelling older adults. We randomly assigned 33 healthy older adults to either a VT group (mean age = 67.5 years) or a control group (mean age = 72.1 years). The VT group received two 1-hour VT training sessions per week for three months (24 sessions). Primary outcome measures collected before and after the intervention period were electromyographic muscle activation onset latencies of the hamstring and gastrocnemius and the center of pressure path, length and movement velocity in standing (reactive balance performance). Secondary outcome measures included isometric peak force and time to isometric peak force of the knee extensors and flexors, the Activities-Specific Balance Confidence Scale score, and fall history. Results revealed that the mean gastrocnemius muscle activation onset latency was significantly longer (22.53 ms) in the VT group after the intervention. The peak force of the knee flexors significantly increased (by 1.58 kg) in the control group over time but not in the VT group. The time to reach peak force in the knee flexors was significantly longer (by 0.51 s) in the control group (but not the VT group) at posttest compared with the pretest value. No other significant group, time, or group-by-time interaction effects were noted. We discussed possible reasons for the failure of three months of martial art training to benefit fall risks among these older adults. [ABSTRACT FROM AUTHOR]

Aerosol mass spectrometry was used to characterize submicron aerosols before and after aging in a Gothenburg Potential Aerosol Mass (Go:PAM) reactor at two suburban sites in China, one in northern China at Changping (CP), Beijing, and a second in southern China at Hong Kong (HK). Organic aerosol (OA) dominated in the ambient nonrefractory particulate matter <1 μm (NR‐PM1) for both CP (42–71%) and HK (43–61%), with a large contribution from secondary OA factors that were semivolatile oxygenated (SVOOA) and low‐volatility oxygenated (LVOOA). Under constant OH exposure, OA enhancement (78–98%) dominated the NR‐PM1 mass increment at both sites, while nitrate was enhanced the most among the inorganic species (7–9%). Overall, the CP site exhibited higher OA oxidation potential and more enhancement of SVOOA than LVOOA (7.5 vs. 2.7 μg/m3), but the reverse was observed in HK (0.8 vs. 2.6 μg/m3). In CP, more enhancement of the less oxygenated SVOOA suggests that aerosol aging was more sensitive to the abundant locally emitted primary OA and volatile organic compound precursors. On the contrary, the more formation of the highly oxidized LVOOA in HK indicates that aerosol aging mainly escalated the degree of oxygenation of OA as ambient aerosol was already quite aged and there was a lack of volatile organic compound precursors. The comparative measurements using the same oxidation system reveal distinct key factors and mechanisms that influence secondary aerosol formation in two suburban locations in China, providing scientific insights to assist formulation of location‐specific mitigation measures of secondary pollution. Plain Language Summary: Atmospheric submicron particles have significant impacts on the climate and human health. A large part of these particles are formed secondarily through successive aging of primary emissions. To study such aging processes, we used a reactor that can provide highly oxidizing conditions to simulate the oxidation of ambient aerosols at accelerated rates. An online mass spectrometer was connected after the reactor to measure changes in aerosol mass concentration and chemical composition between the ambient samples and the oxidized ones. We presented the first comparative measurements of the aging potentials of ambient aerosols in two suburban sites in northern and southern China (Changping District in Beijing, and Hong Kong). Results showed that generally aerosols at the Changping site had higher aging potentials after passing through the oxidation reactor, probably due to more local emissions of precursors, while air masses in Hong Kong were already in a higher oxidation state with lower aging potentials, mainly because of strong impacts from long‐range transported pollution sources. Distinct aerosol aging pathways related to different ambient precursors were observed at the two sites. Understanding of the different characteristics of aerosol aging processes can lead to advances in air quality modeling and pollution management. Key Points: Aging processes of submicron nonrefractory aerosols were investigated comparatively at two suburban sites in northern and southern ChinaBoth sites showed dominant mass increment from organics after aging, but aerosols in northern China had higher aging potentialThe distinct aging processes at the two sites reflected influence from ambient precursors [ABSTRACT FROM AUTHOR]

This study examines the myth of whether China's public assistance scheme is creating welfare dependency. It first analyses the benefit levels of the Urban Minimum Living Standard Guarantee (UMLSG) according to the international poverty measurements. Then it employs in-depth interviews to reveal the life experiences of 15 UMLSG beneficiaries and the views of 8 welfare officials in Guangzhou city. It concludes that the UMLSG assistance is actually too low to reduce the work motivation of beneficiaries. Instead, supplementary welfare associated with the UMLSG contributes to the staying of beneficiaries, to facilitate access to basic housing, health and educational services. [ABSTRACT FROM AUTHOR]

Abstract Rural residential land has been increasingly abandoned in China given the rapid and massive rural-to-urban migration. From the aspect of land-use planning and policy making, it is important to understand the determinants of residential land abandonment across rural areas as well as to know what rural residential land is vulnerable to be abandoned. However, neither of these can be known via qualitative evaluation of residential land abandonment or via remote sensing applications and land-use modelling. In this study, we develop an approach of combining machine learning techniques (Random Forest, Supported Vector Machine, and Naive Bayes) and land-as-an-object analysis to identify the rural residential land that has a high possibility of being abandoned in mountainous areas. We applied this approach to Fang County, Central China. The results indicate a reasonable and reliable prediction of rural residential land abandonment based on our approach, particularly in estimating the potential occurrence of local land abandonment. The geographic characteristics of the land and the living conditions of the land user were found to have relatively significant impacts on rural residential land use. Our approach also provides a pathway to evaluate specific land use and identify its potential change. This approach can be useful for the development of a standardized protocol for the evaluation of residential land abandonment across other rural areas and may be applicable for the investigation of other land types that may be vulnerable to abandonment. Quantitatively assessing the influential factors of residential land use can also provide alternative insights for the development of planning protocols in order to ultimately improve the quality of life and living environments in rural areas. Highlights • Abandoned rural residential land refers to lands with rural houses that are either destroyed/vacant or expected to be so. • Rural residential land use is associated with transport accessibility, elevation and anthropogenic factors. • Land identification using machine learning techniques provides more reliable predictions. • Rural residential land vulnerable to be abandoned was predicted to be substantial.

This study adopted content analysis to examine policy papers concerning the eligibility requirements of the Minimum Living Standard Scheme (MLSS) in China's 31 capital cities. It was found that local officials not only assess applicants’ assets and incomes, but also their living space, quality of home decoration, possession of luxury goods, leisure activities, and behavior. The local governments’ use of a lifestyle assessment approach is caused by financial constraints and the lack of an effective mechanism to check applicants’ incomes. The lifestyle approach leads to regional inequalities in accessing public assistance, because some of the terms, which define the quality of life, are too ambiguous. The lifestyle approach, which requires applicants to live in very poor living conditions and also demonstrate their hardship to local officials, will be a barrier preventing poor people from being integrated into their communities. This study suggests that the key words and terms in the policy documents need to be clearly explained and similar criteria should also be adopted across different regions. It also proposes that the gap between MLSS eligibility criteria in the policy papers and their actual implementation requires further study in order to understand the impact of special local factors and the quality of life of poor people in China.

Purpose There is no comparative research into the Chinese (PSB) police and the Indian police generally and none on police corruption in particular. This paper aims to show what police corruption and malpractices look like in China and India and offer up some suggestions as to why wide spread malpractices persists.Design/methodology/approach Horses’ mouth qualitative research is supported by primary public and police survey data.Findings There are many similarities in corruption “tricks of the trade” in both the countries, as well as in the reasons for its persistence. However, petty police corruption is more pervasive and less subtle in India. But both the forces suffer from politicization of policing, criminalization of politics, culture of tolerance towards substantive justice over procedural justice and master/servant attitude towards the public. In China, the police have administrative powers beyond criminal legislation, and Indian corruption is underscored by the culture of “Jugaad”.Research limitations/implications This is largely a qualitative research, so the usual arguments regarding limitations on its generalization applies. However, the insights in this article may provide some understanding of this under-researched topic and may stimulate further research in this field. It may also offer pointers to potential solutions for practitioners and policymakers.Practical implications By providing data on what corruption looks like and why it persists, policymakers can use the findings of this study to develop measures to address them. In so doing they would create a police service in India and China that is less prone to corruption and misconduct, thereby increasing public trust in these institutions.Social implications Peace and security is a prerequisite condition for economic and social modernization through the rule of law. Reform of the police is a critical success factor in this process. Therefore, by reforming the police, India and China stand a better chance of eradicating poverty and reducing inequality.Originality/value There is little in the way of research into the Chinese Police and none into Chinese police corruption. There is also no comparative study of the Chinese and Indian police generally and none on police corruption in particular. [ABSTRACT FROM AUTHOR]

The ongoing COVID-19 pandemic is a great challenge to mental health, but fine particulate matter (PM 2.5), an increasingly reported risk factor for mental disorders, has been greatly alleviated during the pandemic in many countries. It remains unknown whether COVID-19 outbreak can affect the association between PM 2.5 exposure and the risk of mental disorders. This study aimed to investigate the associations of total and cause-specific mental disorders with PM 2.5 exposure before and after the COVID-19 outbreak in China. Data on daily emergency department visits (EDVs) and hospitalizations of mental disorders from 2016 to 2021 were obtained from Anhui Mental Health Center for Hefei city. An interrupted time series analysis was used to quantify the impact of COVID-19 outbreak on EDVs and hospitalizations of mental disorders. A time-stratified case-crossover analysis was employed to evaluate the association of mental disorders with PM 2.5 exposure before and after the COVID-19 outbreak, especially in the three months following the COVID-19 outbreak. After COVID-19 outbreak, there was an immediate and significant decrease in total mental disorders, including a reduction of 15% (95% CI: 3%–26%) in EDVs and 44% (95% CI: 36%–51%) in hospitalizations. PM 2.5 exposure was associated with increased risk of EDVs and hospitalizations for total and cause-specific mental disorders (schizophrenia, schizotypal and delusional disorders; neurotic, stress-related, and somatoform disorders) before COVID-19 outbreak, but this PM 2.5 -related risk elevation significantly decreased after COVID-19 outbreak, with greater risk reduction at the first month after the outbreak. However, young people (0–45 years) were still vulnerable to PM 2.5 exposure after the COVID-19 outbreak. This study first reveals that the risk of PM 2.5 -related emergency mental disorders decreased after the COVID-19 outbreak in China. The low concentration of PM 2.5 might benefit mental health and greater efforts are required to mitigate air pollution in the post-COVID-19 era. [Display omitted] • A reduction was found in emergency mental disorders after the COVID-19 outbreak. • The adverse effect of PM 2.5 on mental disorder decreased after the COVID-19 outbreak. • The greatest risk reduction occurred in the first month (Feb 2020) after the outbreak. • PM 2.5 remains a threat to mental health for young people even at a low concentration.

This article uses the Integrated Family Services Centres (IFSCs) as an example to illustrate the contractual relationship between the state and non-governmental organizations (NGOs) and the capacities of government officials to implement the contracting-out of services in China. The data from 12 focus groups in 2015 indicated that local governments treated IFSCs as foot soldiers by asking them to fulfil duties beyond their service contracts. Moreover, Guangzhou government’s fragmented service evaluation arrangements and workload-oriented criteria were unable to effectively assess the impact of social work practices. The study concludes that appropriate legislation is required to safeguard the rights of NGOs. [ABSTRACT FROM AUTHOR]

Particulate matter (PM) pollution on the peripheries of Chinese megacities can be as serious as in cities themselves. Given the substantial vehicular emissions in inner-city areas, the direct transport of primary PM (e.g., black carbon and primary organics) and effective formation of secondary PM from precursors (e.g., NOx and volatile organic compounds) can contribute to PM pollution in "buffer" zones between cities. To investigate how traffic emissions in inner-city areas impact these adjacent buffer zones, a suite of real-time instruments were deployed in Panyu, downwind from central Guangzhou, from November to December 2014. Nitrate mass fraction was higher on high-PM days, with the average nitrate-to-sulfate ratio increasing from around 0.35 to 1.5 as the PM mass concentration increased from 10 to 160 μgm-3. Particulate nitrate was strongly correlated with excess ammonium (([NH+ 4 ]/[SO2- 4]-1.5)×[SO2- 4]), with higher concentrations in December than in November due to lower temperatures. The organic mass fraction was the highest across all PM1 levels throughout the campaign. While organic aerosols (OA) were dominated by secondary organic aerosols (SOA = semi-volatile oxygenated organic aerosols + low-volatility oxygenated organic aerosols) as a campaign average, freshly emitted hydrocarbon-like organic aerosols (HOA) contributed up to 40% of OA during high- OA periods, which typically occurred at nighttime and contributed 23.8 to 28.4% on average. This was due to daytime traffic restrictions on heavy-duty vehicles in Guangzhou, and HOA almost increased linearly with total OA concentration. SOA increased as odd oxygen (Ox =O3 +NO2) increased during the day due to photochemistry. A combination of nighttime traffic emissions and daytime photochemistry contributed to the buildup of PM in Panyu. The mitigation of PM pollution in inner-city areas by reducing vehicular traffic can potentially improve air quality in peripheral areas. [ABSTRACT FROM AUTHOR]

Traditional researches on Chinese calligraphy tend to emphasize the analysis of stylistic lineages and the artistic aspect of works of calligraphy. By contrast, the purpose of this paper is to examine how Chinese calligraphy was practiced in Hong Kong in the twentieth and pre-twentieth century, and the historic and societal circumstances in which works of calligraphy were produced. Based on a thematic framework, the work examines pertinent issues in Hong Kong calligraphy including 1.) Chinese intellectuals' encounter with the West; 2.) The propaganda of the revolutionaries; 3.) The pride of Qing dynasty's "left-over subjects"; and 4.) From erudition to contemporary life. Calligraphic works under examination are viewed as both art objects and vehicles projecting a strong sense of social and cultural identity. [ABSTRACT FROM AUTHOR]

Aim The present study aimed to examine effective clinical strategies that facilitate homework adherence among Chinese older adults who participated in group therapy using Instrumental Reminiscence Intervention ( IRI) to reduce depressive symptoms. Methods Examination was based on IRI for 15 groups of older adults, with four to eight participants in each group. Homework assignment was included as a core component of the intervention in each session, except the first session. Particular emphasis was put on both homework design and assignment strategies. Results Two effective strategies were developed. The first was the development of a tactic card as a tool for homework content and assignment. The second strategy was interventionist training. Clinical examples are used to illustrate how these strategies can enhance homework adherence in a Chinese context. Conclusions The two clinical strategies were found to be effective in enhancing homework adherence among Chinese older participants in a group therapy setting. These strategies are recommended for use in group clinical settings for Chinese participants. Geriatr Gerontol Int 2016; 16: 1153-1160. [ABSTRACT FROM AUTHOR]

Background: Different studies in the past have shown that the risk of cancer development is increased in chronic dialysis patients. However, data concerning the cancer risk in Asian dialysis patients was scarce. More importantly, there was lack of information about the cancer-specific mortality in dialysis patients.Methods: A multicenter retrospective cohort study of 6,254 patients who started either chronic peritoneal dialysis or hemodialysis between 1994 and 2014 in 4 renal units in Hong Kong. Patterns of cancer incidence and mortality in our dialysis patients were compared with those of the general population using standardized incidence ratios (SIRs) and standardized mortality ratios (SMRs) respectively.Results: With 14,887 person-years of follow-up, 220 cancers were recorded. The SIR of all cancers was 1.44 (95% CI 1.26-1.65). A trend of an increased SIR was observed in young patients and within the first year of dialysis. Colorectum was the most common site of cancer (20%) while kidney cancer carried the highest risk (SIR 12.28, 95% CI 8.44-17.08). The SMR of all cancers was 0.91 (95% CI 0.72-1.13) and only kidney cancer had higher cancer mortality risk (SMR 4.92, 95% CI 1.80-10.70). SMR was highest in young patients and then decreased with age.Conclusions: The incidence of cancers in our chronic dialysis patients was elevated. Our findings of substantially increased risks in young patients, particularly in relation to kidney cancer, suggest that we can adopt a more individualized approach to cancer screening in chronic dialysis patients.

Objective Previous genome-wide association studies (GWAS), which were mainly based on single-variant analysis, have identified many systemic lupus erythematosus (SLE) susceptibility loci. However, the genetic architecture of this complex disease is far from being understood. The aim of this study was to investigate whether using a gene-based analysis may help to identify novel loci, by considering global evidence of association from a gene or a genomic region rather than focusing on evidence for individual variants. Methods Based on the results of a meta-analysis of 2 GWAS of SLE conducted in 2 Asian cohorts, we performed an in-depth gene-based analysis followed by replication in a total of 4,626 patients and 7,466 control subjects of Asian ancestry. Differential allelic expression was measured by pyrosequencing. Results More than one-half of the reported SLE susceptibility loci showed evidence of independent effects, and this finding is important for understanding the mechanisms of association and explaining disease heritability. ANXA6 was detected as a novel SLE susceptibility gene, with several single-nucleotide polymorphisms (SNPs) contributing independently to the association with disease. The risk allele of rs11960458 correlated significantly with increased expression of ANXA6 in peripheral blood mononuclear cells from heterozygous healthy control subjects. Several other associated SNPs may also regulate ANXA6 expression, according to data obtained from public databases. Higher expression of ANXA6 in patients with SLE was also reported previously. Conclusion Our study demonstrated the merit of using gene-based analysis to identify novel susceptibility loci, especially those with independent effects, and also demonstrated the widespread presence of loci with independent effects in SLE susceptibility genes.

Purpose – This study aims to investigate how Chinese hotel employees (Zhejiang province in mainland China) perceive unethical managerial behavior. It targets to identify any underlying dimensions that exist among the hotel employees. This study also aims to discover any relationship between overall job satisfaction and the derived dimensions. The effects of demographic variables on employees’ job satisfaction and its relationship with unethical managerial behavior are also investigated. Recommendations are presented to hoteliers and human resources practitioners on developing an ethical climate in the hotel industry. Design/methodology/approach – Quantitative mixed methods incorporated both in-depth interviews on identifying 20 unethical managerial behaviors among hotel employees, and statistical analyses of the dimensions of the said behaviors were applied to this research. As quantitative analysis was the principal data analysis method adopted to test the hypotheses on hotel employees’ perception of unethical managerial behavior and job satisfaction, a self-administrated questionnaire was developed. A total of 268 completed questionnaires were collected, and factor analysis, multiple regression, independent t-test and ANOVA were conducted to analyze the data. Findings – Three factors of unethical managerial behavior were developed: unethical treatment of employees; unfair and broken promises to employees; and inequity and unsympathetic treatment of employees. “Unethical treatment of employees” was found to be significantly related to overall job satisfaction among hotel employees in multiple regression analysis. Demographic differences were also found to exert effects on the three factors and overall job satisfaction. Practical implications – This paper successfully identified three underlying dimensions that exist among Chinese hotel employees’ perception of unethical managerial behavior. Three recommendations are presented to hoteliers as well as human resources practitioners for developing an ethical climate in the hotel industry. Originality/value – This study contributes to advance the understanding of the hotel employees’ perception of unethical managerial behavior. The relationship between job satisfaction and the derived three underlying dimensions is discovered. [ABSTRACT FROM AUTHOR]

This paper explores the motivations and aspirations of African students who choose Hong Kong as their destination for university studies. Based on the findings of in-depth interviews with ten African students in Hong Kong, this research postulates that academic reputation and financial incentives are the two main motivations for attending university in Hong Kong. Other factors such as good teaching, research supervision, and treating Hong Kong as a stepping-stone to China also motivate some students. However, this paper identifies a general pattern that indicates most of the African students do not intend to stay behind in Hong Kong after graduation. While internationalization is a major strategic development of Hong Kong universities, there remain an insignificant number of African students on Hong Kong campuses. We suggest that recruiting more African university students can enhance the international profile of Hong Kong universities and strengthen academic internationalization at large.

Objective: To establish Down syndrome (DS)-specific growth charts for Hong Kong Chinese children. Design and setting: Growth data were collected from (1) members of the Hong Kong Down Syndrome Association (cross-sectional); (2) DS children attending special schools or living in residential homes (crosssectional); and (3) the paediatric departments of seven public hospitals (retrospective). Patients: 425 DS children (57% males and 4 3 % females) born in 1977-2000, yielding 4987 observations. Main outcome measures: The LMS method was used to construct reference centile curves of weight, height, body mass index (BMI) from birth until 14 years and head circumference for the first 4 years. Results: The median birth length was 49.8 cm and height at age 14 was 146.7 cm for DS boys. Corresponding figures for DS girls were 49.5 and 142.1 cm. The median birth weight was 3.0 kg for DS boys and 2.9 kg for DS girls. At age 14, 26% DS boys (BMI >22.6 kg/m²) and 12% DS girls (BMI >23.3 kg/m²) were overweight. The median head circumference at birth was 32.8 cm for boys and 32.0 cm for girls. Conclusions: Chinese DS children had a shorter stature, lower weight and tendency to be overweight than local non-DS children. Their growth patterns differed from those of Chinese DS children in Taiwan, and DS children in the USA and Sweden. Growth retardation was most salient during the first year of life.

This study presents an exploratory analysis aimed at improving understanding of the variability of Hong Kong air quality associated with different climate conditions. Significantly negative correlations were found when Niño 3 led particulate matter ⩽10 μm PM) and NO by 2-3 months over the Hong Kong territory, while the other pollutants (e.g., O, SO) showed modest correlations. A significant decreasing trend in visibility was observed during the autumn and winter, which has potential implications for the air-quality degradation and the endangerment of human health in Hong Kong. In an El Niño summer, the visibility was relatively better, while visibility in other seasons was diminished. On the other hand, in La Niña events, significant changes occurred in visibility in winter and autumn. Air pollution indices were less sensitive to the South China Summer Monsoon (SCSM), but a relatively high correlation existed between the East Asian Winter Monsoon (EAWM) and air pollutants. Rainfall was lower during most of the strong EAWM years compared to the weak years. This result suggests that the pollutants that accumulate in Hong Kong are not easy to wash out, so concentrations remain at a higher level. Finally, based on the conditional Air Pollution Index (API) risk assessment, site-specific vulnerabilities were analyzed to facilitate the development of the air-quality warning systems in Hong Kong.

Objective. This study aims to identify the existence of, and relationship between autoantibody clusters and clinical subsets in Chinese SLE patients.Methods. Data from 1928 SLE patients from Hong Kong were analysed. Using cluster analysis, patients were grouped by autoantibodies into clusters. The frequencies of various clinical manifestations were then compared between each cluster. Separate association analyses between individual autoantibodies and clinical manifestations as well as between clinical manifestations were also performed without any prior clustering.Results. Three separate autoantibody clusters were identified, each with significantly different clinical manifestations. Cluster 1 was characterized by anti-dsDNA and the greatest prevalence of renal disorder but the lowest frequencies of other clinical manifestations. Cluster 2 was represented by the predominance of anti-Smith, anti-RNP and aPL, with greater prevalence of malar rash, oral ulcers, arthritis and serositis. Cluster 3 was characterized by anti-Ro and anti-La with greater prevalence of discoid rash, photosensitivity and haematological involvement. Individual association analysis also revealed similar findings. Patients of clusters 2 and 3 were more closely related, while cluster 1 was more distinct, associated with renal disorder only and negatively associated or not associated with other manifestations.Conclusion. We conclude that autoantibody clustering and clinical subsets exist in SLE patients of our locality. These clusters may be viewed as a bipolar spectrum of related autoantibody and clinical manifestations. At one end are patients with over-representation of anti-dsDNA and renal disorder, while at the other end are two distinct autoantibody clusters (anti-Sm/anti-RNP/aPL and anti-Ro/anti-La) with overlapping of other clinical manifestations.

Abstract: Scholarly concerns in organizational citizenship behaviors (OCBs) have increased dramatically over the past two decades. Nevertheless, there are significant issues yet to be addressed and resolved, one of which relates to the influences of cultural values on such voluntary behaviors. In view of the importance of OCB in meliorating hotel service and cultivating customer loyalty, the current study seeks to investigate a possible mechanism through which Chinese values (CVs) may function on employee citizenship behaviors within the hotels in Mainland China. The research questions focus on whether CVs have a direct impact on OCB and its verified antecedents, leader–member exchange (LMX) and employee organizational commitment (OC). Eventually, the research findings have verified the conceptual model and confirmed all the postulated linkages among the constructs under study. [Copyright &y& Elsevier]

This article discusses how China's institutional constraints combine with its integration into the global economy to suppress its workers' rights. The rapid expansion of China's market economy is the consequence of the government's active embrace of global capitalism and global capitalists' ongoing search for new markets and lower production costs. China's traditional socialist labor relationships collapsed as a result of state-owned enterprise(SOE) reform and the emergence of private enterprises. In the wake of these events,China's leaders promulgated new labor legislation and social insurance schemes, but these initiatives fail to safeguard workers' rights effectively. This is because the SOEs fail to compensate their workers properly, local authorities do not actively monitor labor abuses, the judicial system cannot effectively defend workers' rights, and the Chinese government suppresses efforts to organize independent labor unions. In short, global capitalism, together with China's authoritarian polity, has limited workers' rights and undermined their well-being. [ABSTRACT FROM AUTHOR]

The article discusses a study by Mo Yin Mok and colleagues who evaluated the relationship between coronary artery calcium score (CACS), and conventional cardiovascular and disease-specific risk factors in systemic sclerosis (SSc) patients. Findings revealed SSc and disease duration to be independent determinants for CACS. It is inferred that apart from the conventional risk factors including age and hypertension, SSc is an independent risk factor for coronary calcification.

Chan CK. Hong Kong: workfare in the world's freest economy Int J Soc Welfare 2011: 20: 22-32 © 2009 The Author(s), Journal compilation © 2009 Blackwell Publishing Ltd and the International Journal of Social Welfare. Workfare was introduced in many countries to suppress welfare dependency and reduce social security expenditures. However, workfare was launched in Hong Kong when there was only a relatively small social security budget and its citizens still strongly adhered to the ideologies of self-reliance. It was found that workfare has performed several functions in Hong Kong. First, by forcing unemployed claimants to give up benefits, Hong Kong has been able to save on social security expenditures. Second, workfare has combined with Hong Kong's semi-democratic polity so that extremely stigmatising welfare measures have been implemented. Third, it has pushed poor citizens into the labour market without having any protection over wages and working hours. Thus, the combination of workfare and a semi-democratic polity has successfully suppressed Hong Kong's welfare demands and strengthened its self-help spirit. As a result, Hong Kong's minimal social security scheme and its low tax policy have been maintained. [ABSTRACT FROM AUTHOR]

The paper focuses on the close collaborative work our research team has been engaged in with two local schools to study how action research measures may help to facilitate the improvement of the Integrated Humanities (IH) curriculum through school-university partnerships. It attempts to understand action research as a form of cultural practice for education, and examines how such collaborative work with local schools may contribute to sustainable cultural work of education and intervene at different levels of the schooling practices. In all, the paper seeks to offer preliminary analysis and reflection on the re-orientation of Cultural Studies as a research and problem-solving, intellectual and critical project with a potential for long-term input to cultural policy-making. It also aims at examining the role of cultural studies practitioners as action researchers in the process of doing cultural work of education. [ABSTRACT FROM AUTHOR]

This paper explores the construction of local and national identities among secondary school students in post-colonial Hong Kong. As a Chinese society that has undergone a prolonged period of British colonial rule, the reunification of capitalist Hong Kong with the motherland under socialism in 1997 has set the context for a negotiation of identities. It has been revealed that the Government of the Hong Kong Special Administrative Region has tried to foster a stronger sense of national identity and a sense of belonging among the younger generations through its education reform measures in the new millennium. Nation-building is part and parcel of the reform, although it is being interpreted and implemented diversely by local officials, school principals and teachers. The intersecting and overlapping nature of students' different identities has set the parameters of their identity formation but allows different latitudes of observance and/or choice of different identities.

The article focuses on a study of the pandemic influenza A (2009-H1N1) infection in patients of pediatric oncology in Hong Kong, China. It says that a territory-wide study was made to evaluate the clinical course of the infection in hospitalized pediatric oncology patients with such infection. It states that young patients was among the highest risk groups of pandemic H1N1 infection, and that they had experienced an uncomplicated clinical course which allowed them to recover from the infection.

Many commentators contend that the Chinese government adopted an incremental approach to welfare policy reform because its leaders lacked an overall blueprint for it, allowing initiatives to be implemented only after lengthy experimentation. While this perspective has provided an essential account of the implementation and changes of some welfare programmes, it has inadequately addressed the slow progress in rural areas' welfare programmes and the different welfare entitlements for rural and urban residents. Further investigation is therefore required to resolve these anomalies. Using the minimum standard of living scheme (MSLS) as a case example, this article illustrates how the Chinese government's legitimacy needs, during different stages of its economic reforms, have been the principal motivation for the implementation of such schemes. The introduction of an urban MSLS in 1997 aimed to reduce laid-off workers' dissatisfaction following the government's reforms of state-owned enterprises (SOEs). The implementation of a rural MSLS in 2007 was intended principally to minimise conflicts between land-losing farmers and local officials after widespread rural riots. These MSLSs are also minimal and stigmatising public-assistance schemes that fulfil the dual objective of securing a stable political environment for economic reform and maintaining poor people's work ethic for China's mixed economy.

Grown nucleated particles > 50 nm in diameter are an important source of cloud condensation nuclei (CCN) and when the size is > 100 nm, they can also have direct influence on the climate. In this study, the nucleation and growth of new particles in the atmosphere in Hong Kong were investigated during dry season (monthly averaged RH < 75%). The maximum size of grown nucleated particles was generally less than 40 nm during new particle burst and growth events. The exception, accounting for ∼ 20% of all burst and growth events, was those induced by strong photochemical reactions, in which subsequent particle shrinkage occurred. Temporal particle and gas concentration variability and meteorological conditions support the occurrence of particle shrinkage. The shrinkage rate calculated (∼ 8 nm h-1) was close to the growth rate. The observation of particle shrinkage sheds new light on particle transformation dynamics and it would add to the understanding of particle behavior in the atmosphere. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to investigate the risk of cerebrovascular adverse events (CVAEs) in patients with behavioural and psychological symptoms of dementia (BPSD) treated with typical or atypical antipsychotics in Hong Kong Method: This was a retrospective cohort study. Patients aged 65 or above, diagnosed with Alzheimer's disease, vascular or mixed dementia, and first attended the psychiatric service of our unit between 1st January 2000 to 30th June 2007 were studied. The patients were divided into three groups according to their antipsychotic usage. They were compared on sociodemographic and clinical characteristics. The risk of CVAEs was studied by means of Cox regression analysis. Results: The studied cohort consisted of 1089 patients. The antipsychotic non-user, typical and atypical users groups consisted of 363, 654 and 72 patients, respectively. Incidence rate of CVAE for the three groups were 44.6/1000, 32.7/1000 and 49.6/1000 person years, respectively. The risk of developing CVAEs did not differ in typical or atypical antipsychotic user groups compared with non-user group. The adjusted hazard ratio of typical and atypical antipsychotic user groups were 0.964 (95% CI —0.584- 1.591) and 1.036 (95% CI —0.350-3.066), respectively. Subgroup analyses of individual antipsychotic did not show a significant increase in risk of CVAEs. Conclusion: This study showed that there was no statistical difference in risk of cerebrovascular events in treatment of BPSD with typical and atypical antipsychotics compared with non-user group. Nonetheless, given the side effects of antipsychotics, prescription of antipsychotics should be reserved for severe and distressing symptoms with careful consideration.
