Research Summary : Departing from the extant literature, which assumes that firms pursue strong environmental performance as a differentiation strategy, we analyze the general relationship between firms’ competitive strategy and their response to heightened market competition. We find that, using a large sample of Chinese manufacturing firms between 2000 and 2005, intensified market competition has an overall negative impact on firms’ environmental performance. The negative impact is exacerbated in firms adopting a cost‐leadership strategy, but is attenuated in those adopting a differentiation strategy. The results emphasize the importance of including an examination of the particular competitive strategies chosen by firms in seeking to understand the impact of intensified market competition. Managerial Summary : Advocates of corporate social responsibility (CSR) have long argued for the differentiation role of CSR. However, managers may be misguided if the assumed benefits of differentiation critically depend on certain presumptions. In the Chinese context and focusing on the environmental dimension of CSR, our study finds a negative relationship between market competition and corporate environmental performance. It suggests that firms, to a large extent, cannot escape competition via environmental differentiation. Managers should therefore be cautious about the value of strategic investment in CSR as a viable competitive device.

Abstract Supplier development for sustainability is a critical element of sustainable supply chain management and requires extensive multi‐stakeholder collaboration. This article establishes a conceptual four‐stage framework to analyse the collaborative mechanisms of supplier development practices, and presents an exploratory, qualitative analysis to identify the major contributors of sustainable supplier development practices, such as NGOs, industrial associations, consulting firms etc. Based on semi‐structured interviews about 63 organizations from different regions and industries, this article identifies three types of contributor: drivers, facilitators and inspectors. Instead of traditional stakeholder engagement processes, these contributors actively collaborate with buying firms and suppliers to design, implement and evaluate sustainable supplier development programs. The article then provides a matrix to describe the supply chain coverage and supplier performance of supplier development practices, given the absence or positive involvement of facilitators and inspectors. We conclude our study by suggesting future research directions as well as discussing managerial implications. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment

Abstract Whether globalization is good or bad for the environment has been studied intensively in recent years. However, few studies have explicitly provided a general picture of globalization around the world or considered the rich dimensions of globalization outside of economic globalization. By applying the new KOF globalization index in a panel data sample of 166 countries over the 1990–2009 period, our results suggest that, on average, overall carbon emissions rise with higher levels of economic, social and political globalization, although the effect varies by OECD and non‐OECD country group. After decomposing the main contributors of carbon emissions, our further data from the manufacturing and construction sector yield evidence consistent with a pollution haven effect in terms of climate change.

Technological change is one of the most effective methods to reduce carbon intensity. Meanwhile, cities are essential carriers of technological change and carbon emissions. Considering the extensive land expansion in urbanization which always manifests in the density of urban economic activity, this paper analyzes the relationship between urban density and carbon intensity and also the mediating role of directed technological change to explore the interaction among them. First, the authors construct a theoretical model that considers the knowledge production sector, final goods production sector, and technical choice. Second, based on the panel data of 280 cities in China from 2008 to 2017, the authors use the two-way fixed effect regression, mediation-effect regression, and panel-threshold model to examine the results. The results show that: (1) The increase in urban density helps to reduce carbon intensity. (2) Capital-saving technological change is a mediating factor in the path of urban density's effect on carbon intensity. (3) With the increase in market size, the effect of urban density on capital-saving technological change weakens, thereby weakening the inhibitory effect on carbon intensity. Findings can provide a reference for reducing carbon intensity in other countries to formulate reasonable and practical policies for sustainable urbanization, especially for developing countries.

Wolfberry (fruit of Lycium barbarum) has been prized for many years in China for its immunomodulatory property and its high specific antioxidant content. However, clear clinical evidence demonstrating the effect of wolfberry dietary supplementation is still lacking. After our earlier report showing that a proprietary milk-based wolfberry formulation (Lacto-Wolfberry) enhances in vivo antigen-specific adaptive immune responses in aged mice, the present study aimed at demonstrating the effect of dietary Lacto-Wolfberry supplementation on immune functions in the elderly, especially vaccine response known to decline with aging. A 3-month randomized, double-blinded, placebo-controlled study was conducted on 150 healthy community-dwelling Chinese elderly (65-70 years old) supplemented with Lacto-Wolfberry or placebo (13.7 grams/day). Immune response to influenza vaccine was assessed in the study, along with inflammatory and physical status. No serious adverse reactions were reported during the trial, neither symptoms of influenza-like infection. No changes in body weight and blood pressure, blood chemistry or cells composition, as well as autoantibodies levels were observed. The subjects receiving Lacto-Wolfberry had significantly higher postvaccination serum influenza-specific immunoglobulin G levels and seroconversion rate, between days 30 and 90, compared with the placebo group. The postvaccination positive rate was greater in the Lacto-Wolfberry group compared to the placebo group, but did not reach statistical significance. Lacto-Wolfberry supplementation had no significant effect on delayed-type hypersensitivity response and inflammatory markers. In conclusion, long-term dietary supplementation with Lacto-Wolfberry in elderly subjects enhances their capacity to respond to antigenic challenge without overaffecting their immune system, supporting a contribution to reinforcing immune defense in this population.

Based on a panel of 30 provinces and a timeframe from January 2009 to December 2013, we estimate the association between monthly human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) incidence and the relevant Internet search query volumes in Baidu, the most widely used search engine among the Chinese. The pooled mean group (PMG) model show that the Baidu search index (BSI) positively predicts the increase in HIV/AIDS incidence, with a 1% increase in BSI associated with a 2.1% increase in HIV/AIDS incidence on average. This study proposes a promising method to estimate and forecast the incidence of HIV/AIDS, a type of infectious disease that is culturally sensitive and highly unevenly distributed in China; the method can be taken as a complement to a traditional HIV/AIDS surveillance system.

This study applied a situational approach to understanding an environmental problem: PM2.5 (its resulted haze and smog air pollution) in China. Based on a national sample of 374 citizens living in China, it tested a situational model of problem solving and extended it by adding citizens' environmental engagement behaviour as an immediate consequence of their communicative action. Results of a structural equation modelling analysis supported all the causal links in the conceptual model. Moreover, communicative action significantly mediated the relationship between referent criterion and environmental engagement. Problem recognition, constraint recognition, and involvement recognition did not influence environmental engagement directly, but exerted their significant indirect impact via two key mediators in the model: situational motivation in problem solving and communicative action in problem solving. Theoretical and practical implications of the present study were discussed.

Abstract The year 2020 began with a glimpse into the darkness with the onset of the worldwide COVID‐19 pandemic. An invisible, threatening virus has forced many countries to practice restricted movement and impose lockdowns for the sake of their citizens’ safety and well‐being. In response, many business organizations have implemented various remote‐work arrangements. These arrangements have spurred the use of digitalization strategies and have landed many employees in the vulnerable virtual workplace. With employees facing all these uncertainties and vulnerabilities, their commitment to their workplace could come into question. At the same time, organizations facing tremendous challenges are searching for committed employees to navigate through this turbulent time. From a strategic management perspective, organizations could revisit their internal core competencies to prevail through internal corporate social responsibility (CSR) practices. Meanwhile, the rapidly growing pace of digitalization could further augment organizations’ survival and resilience. This research paper showcases the empirical outcomes of the promising match between internal CSR practices and digitalization strategy; and employees’ organizational commitment during times of crisis. The results reveal that internal CSR practices positively stimulate employees’ organizational commitment, while digitalization strategy intercedes in the nexus between internal CSR practices and affective commitment. The empirical outcomes shed light on business organizations and their ability to take a frugal approach in turbulent times.

To encourage economic progress, China's government has been pushing domestic consumption as a substitute for its waning growth in investment and exports. It has also been promoting greener policies for growth, of which green consumerism is a prime component. By examining the economy through the lens of household energy consumption, this paper lays out the challenges the nation must overcome through green consumption. We explore the trends in household energy use and decompose energy used indirectly by households into six factors: changes in total population, urbanization rate, energy efficiency, interindustry input mix, household consumption preferences, and per capita household consumption level. Doing so yields insights into how progress in industrial technology, household income, urbanization, and lifestyles has affected energy use in the production of goods and services used by households. It also offers policy suggestions on how China might guide lifestyle changes to effect green consumption.

As China’s economy enters the “new normal” phase, its growth model has gradually changed to focus more on domestic consumption. In this paper, we examine regional disparities in households’ total (direct and indirect) energy use in China from 2002 to 2012. Using a structural decomposition approach, we examine how changes in China’s technology, economic structure, urbanization, lifestyle, and interregional trade affect household energy use across different regions. We find that rising income levels contributed most to energy usage. Improved energy efficiency offset the rising effects of heightened household consumption in most regions. Rural-to-urban migration played an important role in enhancing energy use in all regions from 2002 to 2012. Moreover, households started to rely more heavily on interregional trade of final goods and services to meet their consumption demands. Based on this multi-regional and multi-angle study, we provide some regional-specific policies that would help curb household energy demand and promote sustainable consumption in China.

The emergence of multiple and shifting modes of governance both intranationally and supranationally has posed difficulties for analysts accustomed to refining or testing singular types of politics. When confronted with this changing complexity, a comprehensive framework can be a very useful diagnostic and organizational tool. This article devises one such conceptual framework to clarify and systematize varieties of state autonomy and state–society relations. By combining fundamental conceptions of action, elemental control mechanisms, and basic types of interaction, a comprehensive framework is constructed for characterizing and comparing governance modes in a conceptually coherent manner. Many of the abstract spaces within this conceptual field share affinities with types of state autonomy and state–society relations depicted in major theoretical approaches to national politics (i.e., authoritarianism, statism, pluralism, corporatism, institutionalism, and Marxism). This article uses this conceptual framework to systematize these major governance modes and to illuminate their coexistence in supranational governance by examining the European Union policy process.

Wind-related disasters will bring more devastating consequences to cities in the future with a changing climate, but relevant studies have so far provided insufficient information to guide adaptation actions. This study aims to provide an in-depth elaboration of the contents discussed in open access literature regarding wind disaster adaptation in cities. We used the Latent Dirichlet Allocation (LDA) to refine topics and main contents based on 232 publications (1900 to 2019) extracted from Web of Science and Scopus. We conducted a full-text analysis to filter out focal cities along with their adaptation measures. The results show that wind disaster adaptation research in cities has formed a systematic framework in four aspects: 1) vulnerability and resilience of cities, 2) damage evaluation, 3) response and recovery, and 4) health impacts of wind disaster. Climate change is the background for many articles discussing vulnerability and adaptation in coastal areas. It is also embedded in damage evaluation since it has the potential to exacerbate disaster consequences. The literature is strongly inclined towards more developed cities such as New York City and New Orleans, among which New York City associated with Hurricane Sandy ranks first (38/232). Studies on New York City cover all the aspects, including the health impacts of wind disasters which are significantly less studied now. Distinct differences do exist in the number of measures regarding the adaptation categories and their subcategories. We also find that hard adaptation measures (i.e., structural and physical measures) are far more popular than soft adaptation measures (i.e., social and institutional measures). Our findings suggest that policymakers should pay more attention to cities that have experienced major wind disasters other than New York. They should embrace the up-to-date climate change study to defend short-term disasters and take precautions against long-term changes. They should also develop hard-soft hybrid adaptation measures, with special attention on the soft side, and enhance the health impact study of wind-related disasters.

The Internet technology has had a visible impact on the daily work and lives of people, especially the youth. This paper aims to investigate the influence of Internet technology on labour income as well as the channels through which income is affected, with a variety of empirical methods. Using the Chinese Family Panel Survey (CFPS) in 2014 and 2018, we discover that a ‘digital gap’ in Internet use is emerging. First, young labour force with higher income and education, urban identity, and working in high-skilled industry earn more from Internet use than their peers. Second, the return of operational income is higher than the return of wage income. Third, the return on long-term Internet use is higher than the return on short-term Internet use; however, the return has tended to decline, particularly among the bottom 25% income groups. Forth, the Internet affects their income through three main channels: assisting learning, improving working efficiency, and promoting information sharing. We also offer a few policy suggestions (e.g. improving the allocation of Internet resources).

Pancreatic cancer (PC), one of the most lethal malignancies, accounts for 8%-10% of digestive system cancers, and the incidence is increasing. Surgery, chemotherapy, and radiotherapy have been the main treatment methods but are not very effective. However, only 20% of patients have the opportunity to undergo surgical operation. Approximately 30-40% of patients present with locally advanced, unresectable pancreatic cancer because of invasion of mesenteric vessels or adjacent organs. The first patient with unresectable pancreatic cancer was treated with Intraoperative radiotherapy (IORT) in 1959 [1]. Since then, new surgical and radiotherapeutic techniques have been developed, clinical trials have provided new evidence, and intriguing long-term effects have emerged from global metadatabases. IORT has the advantages of more accurate target, better local control rate, less complications, longer survival time and better life quality. During the past decade, IORT has been applied in some hospitals in the world, but there is little agreement on technical details and standards. A guidelines of IORT in pancreatic cancer is therefore necessary and timely. To develop standardized criteria for the application of IORT in pancreatic cancer, the experts from China to discuss treatment methods and arrive at a consensus on the indications, contraindications, and preferred techniques of IORT in pancreatic cancer. This detailed and agreed technical description of IORT may have implications on training, assessment, quality control, and future research.

As the West’s centrality fades, the global South may have a decisive influence in shaping future world order. Will that future see a retreat from globalisation to hard-edged particularisms? Or will the emerging post-Westphalian global society let the global South take over the baton of cosmopolitan institution building in its own way? This article draws on a multi-country survey of educated youth to find promising signs of imagined common ground with other countries. It suggests the flavours of cosmopolitan integration that the global South is likely to support in coming decades.

Abstract Background Suicidal ideation is subject to serious underestimation among existing public health studies. While numerous factors have been recognized in affecting suicidal thoughts and behaviors (STB), the associated environmental risks have been poorly understood. Foremost among the various environment risks were air pollution, in particular, the PM2.5. The present study attempted to examine the relationship between PM 2.5 level and local weekly index of suicidal ideation (ISI). Methods Using Internet search query volumes in Baidu (2017), the largest internet search engine in China, we constructed a prefectural panel data (278 prefectures, 52 weeks) and employed dynamic panel GMM system estimation to analyze the relationship between weekly concentration of PM2.5 (Mean = 87 μg·m − 3 ) and the index of suicidal ideation (Mean = 49.9). Results The results indicate that in the spring and winter, a 10 μg·m − 3 increase in the prior week’s PM 2.5 in a Chinese city is significantly associated with 0.020 increase in ISI in spring and a 0.007 increase in ISI in winter, after taking account other co-pollutants and meteorological conditions. Conclusion We innovatively proposed the measure of suicidal ideation and provided suggestive evidence of a positive association between suicidal ideation and PM 2.5 level.

One of sociological human ecology's classic hypotheses posits the existence of a positive relationship between social status and residence. The more similar the social characteristics of two populations, the greater their degree of residential propinquity. This study examines that hypothesis with data for the Han majority and each of the fifty‐five minority nationalities enumerated in the 1982 Census of the People's Republic of China. We find support for the hypothesis when we use a segregation measure that reflects the degree of unevenness of the residential distribution of a minority population from the Han. The paper also addresses the implications of these findings for the social and economic development of the Chinese minorities.

Frogs play an important role in ecological systems, while frog species across the globe are threatened and declining. Therefore, it is valuable to estimate the frog population based on an intelligent computer system. Due to the success of deep learning (DL) in various pattern recognition tasks, previous studies have used DL-based methods for frog call analysis. However, the performance of DL-based systems is highly affected by their input (feature representation). In this study, we develop a frog calling activity detection system for continuous field recordings using a light convolutional neural network (CNN) with multi-view spectrograms. To be specific, a sliding window is first applied to continuous recordings for obtaining audio segments with a fixed duration. Then, the background noise is filtered out. Next, a multi-view spectrogram is used for characterizing those segments, which has more distinctive information than a single-view spectrogram. Finally, a lightweight CNN model is used for the detection of frog calling activity with a twin loss, where different train and test sets are used to validate the model’s robustness. Our experimental results indicate that the highest macro F1-score was 99.6 ± 0.2 and 96.4 ± 2.0 using 2016 and 2017 as the train data respectively, where CNN-GAP is used as the model with multi-view spectrogram as the input.

Abstract International migration is changing the face of Europe, and the rapidly growing presence of the Chinese diaspora in Italy illustrates how longstanding migratory patterns are subject to global socioeconomic changes. Both Italy and China are traditionally points of emigration, but today, there is a unique juncture in the historical experience whereupon one community, the Italians, has become host to the other, the Chinese. Italy, with its promise of new or underdeveloped economic niches and relatively lax immigration policies, has served as a particular draw for Chinese migrants over the last two decades. The following article seeks to present a clearer picture of 20th century Chinese migration to Italy. First, I will establish the present state of immigration in Italy followed by an overview of contemporary Chinese migration to Italy. Second, I will consider the Zhejiangese migration to Europe, including Italy, and the motivations behind these global movements. Third, I will examine the traces of historical influence on the livelihoods of the Chinese residing in Italy today. The development of the Chinese community in Italy touches upon the need to learn from the past as Italy, and Europe, determines how to administer to and integrate the newest members of its society.

Global energy governance institutions pressure China, which has ungoverned domestic energy spaces, to reform and strengthen its capacity for domestic energy governance. Rather than reform, China has attempted to create an alternative global energy order and establish a leadership role using the BRICS framework. However, BRICS exist in the global ungoverned energy space and have not prioritised energy governance. Additionally, BRICS practice shared leadership, undermining potential Chinese leadership. Beijing has subsequently shifted to the “Silk Road Economic Belt,” a vehicle for uncontested Chinese leadership in energy.
