Atmospheric PM2.5 pollution has become a prominent environmental problem in China, posing considerable threat to sustainable development. The primary driver of PM2.5 pollution in China is urbanization, and its relationship with PM2.5 concentration has attracted considerable recent academic interest. However, the spatial heterogeneity of the effect of urbanization on PM2.5 concentration has not been fully explored. This study sought to fill this knowledge gap by focusing on the Beijing–Tianjin–Hebei (BTH) urban agglomeration. Urbanization was decomposed into economic urbanization, population urbanization, and land urbanization, and four corresponding indicators were selected. A geographically weighted regression model revealed that the impact of multidimensional urbanization on PM2.5 concentration varies significantly. Economically, urbanization is correlated positively and negatively with PM2.5 concentration in northern and southern areas, respectively. Population size showed a positive correlation with PM2.5 concentration in northwestern and northeastern areas. A negative correlation was found between urban land size and PM2.5 concentration from central to southern regions. Urban compactness is the dominant influencing factor that is correlated positively with PM2.5 concentration in a major part of the BTH urban agglomeration. On the basis of these findings, BTH counties were categorized with regard to local policy recommendations intended to reduce PM2.5 concentrations.

India has recently emerged as a major political and economic power in the world. The financial crisis that engulfed the world in 2008 needed developing countries like India to lead the rescue and recovery, instead of G7 westerns countries who dealt with such crisis in the past. Recently, discussions and negotiations are going amongst G20 countries regarding a new global financial architecture (G-20 Summit, 2008). The outcome will affect the relevant industries in India and hence it is a public interest issue for the actuarial profession in the country. Increased and more intrusive and costly regulations and red tapes are likely to be a part of the new deal (Economic Survey 2009-10). The objective of this paper is to study the perception of higher level authorities in Insurance sector regarding the role of regulator in minimizing the impact of global financial crisis. The primary data has been collected from 200 authorities in insurance industry. The data has been analyzed with statistical tools like MS-Excel. On the basis of the findings, various measures and policy recommendations for insurers have been suggested to minimize the impact of crisis.

The article examines the development of advanced digital manufacturing (as outlined in the ‘Made-in-China 2025’ government plan) from the perspective of the changing socio-technical paradigms of production. The analysis focuses on the transformations of value chains and work, based on theories of social shaping of technology, regulation theory and regimes of production. Analytically, the author proposes to distinguish between ‘production-driven’ and ‘distribution-driven’ pathways of manufacturing digitalisation. The transformation of semi-rural industrial areas (‘Taobao villages’, named after China’s largest e-commerce platform Taobao) into mass production clusters for e-commerce is depicted as a paradigmatic model of distribution-driven transformation and as a characteristic Chinese strategy in this field. The article examines the impact on industry supply chains and work, leading to ever-more precarious conditions of employment. Policy recommendations focus on local strategies to stabilise supply chain structures and working conditions, as an alternative to the present top-down approaches to manufacturing modernisation in China.

Purpose The purpose of the study is to develop a scale to identify and measure cultural factors and brand loyalty among rural consumers. The study also seeks to analyze the impact of identified cultural factors on the overall brand loyalty of rural consumers. Design/methodology/approach A questionnaire was developed to measure cultural factors and brand loyalty of rural consumers. Exploratory factor analysis was carried out to identify cultural factors, and a regression analysis was carried out to study the impact of the identified factors on brand loyalty. Findings Four dimensions of culture were identified from the study, i.e. virtuousness, religion, sociability and ethnocentrism. The analysis reveals that virtuousness is the most influencing factor on brand loyalty of rural consumers, followed by sociability and religion. Ethnocentrism was found to have insignificant influence on brand loyalty. Research limitations/implications The Indian rural market is a market of opportunity and unlimited business potential. An understanding of the cultural factors of rural markets and their influence on brand loyalty would help marketers and business organizations build an appropriate market strategy to explore benefits. Originality/value The paper attempts to explore the influence of certain cultural factors on the brand loyalty of Indian rural consumers, which has not been researched extensively. This provides a good insight for all marketers who want to succeed in this market.

During extreme air pollution events, such as bushfires, public health agencies often recommend that vulnerable individuals visit a nearby public building with central air conditioning to reduce their exposure to smoke. However, there is limited evidence that these “cleaner indoor air shelters” reduce exposure or health risks. We quantified the impact of a “cleaner indoor air shelter” in a public library in Port Macquarie, NSW, Australia when concentrations of fine particulate matter (PM2.5) were elevated during a local peat fire and nearby bushfires. Specifically, we evaluated the air quality improvements with central air conditioning only and with the use of portable high efficiency particulate air (HEPA) filter air cleaners. We measured PM2.5 from August 2019 until February 2020 by deploying pairs of low-cost PM2.5 sensors (i) inside the main library, (ii) in a smaller media room inside the library, (iii) outside the library, and (iv) co-located with regulatory monitors located in the town. We operated two HEPA cleaners in the media room from August until October 2019. We quantified the infiltration efficiency of outdoor PM2.5 concentrations, defined as the fraction of the outdoor PM2.5 concentration that penetrates indoors and remains suspended, as well as the additional effect of HEPA cleaners on PM2.5 concentrations. The infiltration efficiency of outdoor PM2.5 into the air-conditioned main library was 30%, meaning that compared to the PM2.5 concentration outdoors, the concentrations of outdoor-generated PM2.5 indoors were reduced by 70%. In the media room, when the HEPA cleaners were operating, PM2.5 concentrations were reduced further with a PM2.5 infiltration efficiency of 17%. A carefully selected air-conditioned public building could be used as a cleaner indoor air shelter during episodes of elevated smoke emissions. Further improvements in indoor air quality within the building can be achieved by operating appropriately sized HEPA cleaners.

In an ageing society, over-60s’ problems take an important place in the social policy. The State should be prepared for various implications, both positive and negative, of the ageing of the population, and should treat the potential problems of citizens as a challenge and an opportunity for the development of social policy, and within its framework, the policy aimed at the senior citizens. The senior citizens, by all means, constitute an important age group. This type of policy should be focused on both early and late old age people, addressing their different needs and expectations. This article attempts to show the challenges and the role of social policy addressed to the seniors, both at the early and late old age, especially at the local community level. The impact of the article is analysed in the three dimensions described, i.e. a brief outline of the ageing of the population from a demographic perspective, social policy towards seniors at the early and late old age, the challenge the 60 and over pose to the local policy versus their resources.

Urban agglomeration polders (UAPs) are often used to control flooding in eastern China. The impacts of UAPs on individual flood events have been extensively examined, but how flood risks are influenced by UAPs is much less examined. This study aimed to explore a three-dimensional joint distribution of annual flood volume, peak flow and water level to examine UAPs’ impact on flood risks based on hydrological simulations. The dependence between pairwise hydrological characteristics are measured by rank correlation coefficients and graphs. An Archimedean Copula is applied to model the dependence structure. This approach is applied to the Qinhuai River Basin where UAPs are used proactively for flood control. The result shows that the Frank Copula can better represent the dependence structure in the Qinhuai River Basin. UAPs increase risks of individual flood characteristics and integrated risks. UAPs have a relatively greater impact on water level than the other two flood characteristics. It is noted that the impact on flood risk levels off for greater floods.

This paper examines the implications of New Labour's approaches to crime and disorder on CCTV implementation. It concentrates on the usage of CCTV as one of the government's many initiatives, which are intended to address crime and disorder, including the fear of crime. In particular, the impact of the 1998 Crime and Disorder Act (CDA) - the cornerstone of this government's approach to crime reduction - on the generation of such strategies is examined. The paper revisits neo-Marxist and Foucauldian analyses of the so-called surveillance society through an appraisal of the complex relationship between structure and agency in the formulation and implementation of anti-crime and disorder strategies. Drawing on fieldwork data the paper considers the activities of practitioners at a local level by focusing on the influence of central government, local communities and 'common sense' thinking based on certain criminological theories. It is argued that a myriad of micro-level operations, obligations, processes, managerial concerns (particularly conflict resolution and resource issues), structures and agency - as well as the indirect influence of central government - shape CCTV policy. Ultimately, the creation of new local policy contexts under the CDA emphasise the need to consider incremental and malleable processes concerning the formulation of CCTV policy. In turn, this allows a re-examination of theoretical accounts of surveillance, and their attendant assumptions of sovereign or disciplinary power.

As a sudden public health event, the COVID-19 epidemic has brought a tremendous impact on the economic and social development of China. Its biggest and most direct impact is in the tertiary industry, especially the cultural tourism industry, which has a more far-reaching impact. This paper takes Guangxi as an example to study the current situation, problems, and future development direction of the cultural tourism industry in the post-epidemic era. The study found that the response to the epidemic in ethnic minority areas represented by Guangxi was timely and rapid, but due to their industrial resilience and the impact of the epidemic, the revitalization of the culture and tourism industry is still facing severe challenges. Therefore, this article put forward the key countermeasure to promote the cultural tourism industry revitalization of ethnic minority areas from list management, elements of development management, project construction, industry integration, and international cooperation, to provide policy recommendations and theoretical basis for the revitalization of the cultural tourism industry in ethnic minority areas.

The layout of public service facilities and their accessibility are important factors affecting spatial justice. Previous studies have verified the positive influence of public facilities accessibility on house prices; however, the spatial scale of the impact of various public facilities accessibility on house prices is not yet clear. This study takes transportation analysis zone of Wuhan city as the spatial unit, measure the public facilities accessibility of schools, hospitals, green space, and public transit stations with four kinds of accessibility models such as the nearest distance, real time travel cost, kernel density, and two step floating catchment area (2SFCA), and explores the multiscale effect of public services accessibility on house prices with multiscale geographically weighted regression model. The results show that the differentiated scale effect not only exists among different public facility accessibilities, but also exists in different accessibility models of the same sort of facility. The article also suggests that different facilities should adopt its appropriate accessibility model. This study provides insights into spatial heterogeneity of urban public service facilities accessibility, which will benefit decision making in equal accessibility planning and policy formulation for the layout of urban service facilities.
