The urbanization of the world, which is one of the most impressive facts of modern times, has wrought profound changes in virtually every phase of social life. The recency and rapidity of urbanization in the United States accounts for the acuteness of our urban problems and our lack of awareness of them. Despite the dominance of urbanism in the modern world we still lack a sociological definition of the city which would take adequate account of the fact that while the city is the characteristic locus of urbanism, the urban mode of life is not confined to cities. For sociological purpose a city is a relatively large, dense, and permanent settlement of heterogenous individuals. Large numbers account for inidividual variability, the relative absence of intimate personal acquaintanceship, the segmentalization of human relations which are largely anonymous, superficial, and transitory, and associated characteristic. Density involves diversification and specialization, the coincidence of social relations, glaring contrasts, a complex pattern of segregation, the predominance of formal social control, and accentuated friction, among other phenomena. Heterogeneity tends to break down rigid social structures and to produce increased mobility, instability, and insecurity, and the affilitation of the individuals with a variety of intersecting and tangential social groups with a high rate of membership turnover. The pecuniary nexus tends to displace personal relations, institutions tend to cater to mass rather than to individual requirements. The individual thus becomes effective only as he acts through organized groups. The complicated phenomena of urbanism may acquire unity and coherence if the sociological analysis proceeds in the light of such a body of theory. The empirical evidence concerning the ecology, the social organization, and the social psychology of the urban mode of life confirms the fruitfulness of this approach.

One of the most important developments over the past three decades has been the spread of liberal economic ideas and policies throughout the world. These policies have affected the lives of millions of people, yet our most sophisticated political economy models do not adequately capture influences on these policy choices. Evidence suggests that the adoption of liberal economic practices is highly clustered both temporally and spatially. We hypothesize that this clustering might be due to processes of policy diffusion. We think of diffusion as resulting from one of two broad sets of forces: one in which mounting adoptions of a policy alter the benefits of adopting for others and another in which adoptions provide policy relevant information about the benefits of adopting. We develop arguments within these broad classes of mechanisms, construct appropriate measures of the relevant concepts, and test their effects on liberalization and restriction of the current account, the capital account, and the exchange rate regime. Our findings suggest that domestic models of foreign economic policy making are insufficient. The evidence shows that policy transitions are influenced by international economic competition as well as the policies of a country's sociocultural peers. We interpret the latter influence as a form of channeled learning reflecting governments' search for appropriate models for economic policy.

BACKGROUND: Although at present there is broad agreement among researchers, health professionals, and policy makers on the need to control and combat health misinformation, the magnitude of this problem is still unknown. Consequently, it is fundamental to discover both the most prevalent health topics and the social media platforms from which these topics are initially framed and subsequently disseminated. OBJECTIVE: This systematic review aimed to identify the main health misinformation topics and their prevalence on different social media platforms, focusing on methodological quality and the diverse solutions that are being implemented to address this public health concern. METHODS: We searched PubMed, MEDLINE, Scopus, and Web of Science for articles published in English before March 2019, with a focus on the study of health misinformation in social media. We defined health misinformation as a health-related claim that is based on anecdotal evidence, false, or misleading owing to the lack of existing scientific knowledge. We included (1) articles that focused on health misinformation in social media, including those in which the authors discussed the consequences or purposes of health misinformation and (2) studies that described empirical findings regarding the measurement of health misinformation on these platforms. RESULTS: A total of 69 studies were identified as eligible, and they covered a wide range of health topics and social media platforms. The topics were articulated around the following six principal categories: vaccines (32%), drugs or smoking (22%), noncommunicable diseases (19%), pandemics (10%), eating disorders (9%), and medical treatments (7%). Studies were mainly based on the following five methodological approaches: social network analysis (28%), evaluating content (26%), evaluating quality (24%), content/text analysis (16%), and sentiment analysis (6%). Health misinformation was most prevalent in studies related to smoking products and drugs such as opioids and marijuana. Posts with misinformation reached 87% in some studies. Health misinformation about vaccines was also very common (43%), with the human papilloma virus vaccine being the most affected. Health misinformation related to diets or pro-eating disorder arguments were moderate in comparison to the aforementioned topics (36%). Studies focused on diseases (ie, noncommunicable diseases and pandemics) also reported moderate misinformation rates (40%), especially in the case of cancer. Finally, the lowest levels of health misinformation were related to medical treatments (30%). CONCLUSIONS: The prevalence of health misinformation was the highest on Twitter and on issues related to smoking products and drugs. However, misinformation on major public health issues, such as vaccines and diseases, was also high. Our study offers a comprehensive characterization of the dominant health misinformation topics and a comprehensive description of their prevalence on different social media platforms, which can guide future studies and help in the development of evidence-based digital policy action plans.

The importance of social trust has become widely accepted in the social sciences. A number of explanations have been put forward for the stark variation in social trust among countries. Among these, participation in voluntary associations received most attention. Yet there is scant evidence that participation can lead to trust. In this article, the authors examine a variable that has not gotten the attention it deserves in the discussion about the sources of generalized trust, namely, equality. They conceptualize equality along two dimensions: economic equality and equality of opportunity. The omission of both these dimensions of equality in the social capital literature is peculiar for several reasons. First, it is obvious that the countries that score highest on social trust also rank highest on economic equality, namely, the Nordic countries, the Netherlands, and Canada. Second, these countries have put a lot of effort in creating equality of opportunity, not least in regard to their policies for public education, health care, labor market opportunities, and (more recently) gender equality. The argument for increasing social trust by reducing inequality has largely been ignored in the policy debates about social trust. Social capital research has to a large extent been used by several governments and policy organizations to send a message to people that the bad things in their society are caused by too little volunteering. The policy implications that follow from the authors' research is that the low levels of trust and social capital that plague many countries are caused by too little government action to reduce inequality. However, many countries with low levels of social trust and social capital may be stuck in what is known as a social trap . The logic of such a situation is the following. Social trust will not increase because massive social inequality prevails, but the public policies that could remedy this situation cannot be established precisely because there is a genuine lack of trust. This lack of trust concerns both “other people” and the government institutions that are needed to implement universal policies.

BACKGROUND: In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. METHODS: GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. FINDINGS: Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990-2010 time period, with the greatest annualised rate of decline occurring in the 0-9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10-24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10-24 years were also in the top ten in the 25-49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50-74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. INTERPRETATION: As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and development investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

OBJECTIVES: To review the scientific data on the role of sexually transmitted diseases (STDs) in sexual transmission of HIV infection and discuss the implications of these findings for HIV and STD prevention policy and practice. METHODS: Articles were selected from a review of Medline, accessed with the OVID search engine. The search covered articles from January 1987 to September 1998 and yielded 2101 articles. Methods used to uncover articles which might have been missed included searching for related articles by author, and combing literature reviews. In addition, all abstracts under the category "sexually transmitted diseases" from the XI and XII International Conferences on AIDS (Vancouver 1996 and Geneva 1998) and other relevant scientific meetings were reviewed. Efforts were made to locate journal articles which resulted from the research reported in the identified abstracts. All original journal articles and abstracts which met one of the following criteria were included: (1) studies of the biological plausibility or mechanism of facilitation of HIV infectiousness or susceptibility by STDs, (2) prospective cohort studies (longitudinal or nested case-control) which estimate the risk of HIV infection associated with specific STDs or STD syndromes, or (3) intervention studies which quantitate the effect which STD treatment can have on HIV incidence. RESULTS: Strong evidence indicates that both ulcerative and non-ulcerative STDs promote HIV transmission by augmenting HIV infectiousness and HIV susceptibility via a variety of biological mechanisms. These effects are reflected in the risk estimates found in numerous prospective studies from four continents which range from 2.0 to 23.5, with most clustering between 2 and 5. The relative importance of ulcerative and non-ulcerative STDs appears to be complex. Owing to the greater frequency of non-ulcerative STDs in many populations, these infections may be responsible for more HIV transmission than genital ulcers. However, the limited reciprocal impact of HIV infection on non-ulcerative STDs and the evidence that non-ulcerative STDs may increase risk primarily for the receptive partner (rather than bidirectionally) may modulate the impact of these diseases. The results of two community level randomised, controlled intervention trials conducted in Africa suggest that timely provision of STD services can substantially reduce HIV incidence, but raise additional questions about the optimal way to target and implement these services to achieve the greatest effect on HIV transmission. CONCLUSIONS: Available data leave little doubt that other STDs facilitate HIV transmission through direct, biological mechanisms and that early STD treatment should be part of a high quality, comprehensive HIV prevention strategy. Policy makers, HIV prevention programme managers, and providers should focus initial implementation efforts on three key areas: (i) improving access to and quality of STD clinical services; (ii) promoting early and effective STD related healthcare behaviours; and (iii) establishing surveillance systems to monitor STD and HIV trends and their interrelations.

PURPOSE: This study illuminates the concept of "aging in place" in terms of functional, symbolic, and emotional attachments and meanings of homes, neighbourhoods, and communities. It investigates how older people understand the meaning of "aging in place," a term widely used in aging policy and research but underexplored with older people themselves. DESIGN AND METHODS: Older people (n = 121), ranging in age from 56 to 92 years, participated in focus groups and interviews in 2 case study communities of similar size in Aotearoa New Zealand, both with high ratings on deprivation indices. The question, "What is the ideal place to grow older?" was explored, including reflections on aging in place. Thematic and narrative analyses on the meaning of aging in place are presented in this paper. RESULTS: Older people want choices about where and how they age in place. "Aging in place" was seen as an advantage in terms of a sense of attachment or connection and feelings of security and familiarity in relation to both homes and communities. Aging in place related to a sense of identity both through independence and autonomy and through caring relationships and roles in the places people live. IMPLICATIONS: Aging in place operates in multiple interacting ways, which need to be taken into account in both policy and research. The meanings of aging in place for older people have pragmatic implications beyond internal "feel good" aspects and operate interactively far beyond the "home" or housing.

This study investigates the relationship between organisational commitment and employee perceptions of corporate social responsibility (CSR) within a model which draws on social identity theory.Specifically, we examine the impact of three aspects of socially responsible behaviour on affective commitment: employee perceptions of corporate social responsibility in the community, procedural justice in the organisation and the provision of employee training.The relationship between affective commitment and each aspect of CSR is investigated within a model which controls for job satisfaction, leadership, employee level, age and tenure and discriminates between the direct and moderating effects of gender.The analysis is based on a sample of 4,712 employees drawn from a financial services company.The results provide evidence of a positive relationship between all three measures of CSR and affective commitment and suggest that the contribution of CSR to affective commitment is at least as great as that of job satisfaction.Corporate social responsibility in the community has positive implications therefore not only to external stakeholders but also to the commitment of employees within the organisation.While no direct effect was found between gender and affective commitment, the results emphasise the moderating effect of gender on the relationship between CSR and affective commitment. The Contribution of Corporate Social Responsibility to OrganisationalCommitment * = significant at 0.10 level ** = significant at 0.05 level *** = significant at 0.01 level

Public policy instrumentation and its choice of tools and modes of operation are treated either as a kind of evidence (governing means making regulations, taxing, entering into contracts, communicating, etc.) or as if the questions it raises (the properties of instruments, justifications for choosing them, their applicability, etc.) are part of a rationality of methods without any autonomous meaning. This paper aims to explain the significance of a political sociology approach to public policy instruments in accounting for processes of public policy change: (1) public policy instrumentation is a major issue in public policy, since it reveals a (fairly explicit) theorization of the relationship between the governing and the governed: every instrument constitutes a condensed form of knowledge about social control and ways of exercising it; and (2) instruments at work are not neutral devices: they produce specific effects, independently of the objective pursued (the aims ascribed to them), which structure public policy according to their own logic.

Over the past two decades, "active aging" has emerged in Europe as the foremost policy response to the challenges of population aging. This article examines the concept of active aging and how it differs from that of "successful aging." In particular, it shows how active aging presents a more holistic, life course-oriented approach than successful aging. We provide a critical perspective on active aging too by, first, tracing its emergence in Europe and then showing how, in practice, it has been dominated by a narrow economic or productivist perspective that prioritizes the extension of working life. It has also been gender blind. Nonetheless, it is argued that an active aging approach has the potential to enable countries to respond successfully to the challenges of population aging because of its comprehensive focus and emphasis on societal as well as individual responsibility. Finally, we set out the basic principles that need to be followed if the full potential of active aging is to be achieved.

The Art and Craft of Policy Analysis "Even after half a century of reading public policy works, if I were to be limited to one professional book, it would be The Art and Craft of Policy Analysis. Aaron Wildavsky, a founder of the field, was determined to teach its members to above all question 'received' wisdom. Criticism, while essential, is not enough, he counseled. Policy analysis must contribute to addressing problems. The mark of good public policy is whether today's problems are less divisive and more soluble than those previously faced. At the end of the 1970s, after two tumultuous decades of revolutionary policies affecting civil rights, social welfare and the environment, Wildavsky was positive about the contribution of policy. Can we come to the same judgement today? This book can teach the reader how to do the analysis.

Transformative artificially intelligent tools, such as ChatGPT, designed to generate sophisticated text indistinguishable from that produced by a human, are applicable across a wide range of contexts. The technology presents opportunities as well as, often ethical and legal, challenges, and has the potential for both positive and negative impacts for organisations, society, and individuals. Offering multi-disciplinary insight into some of these, this article brings together 43 contributions from experts in fields such as computer science, marketing, information systems, education, policy, hospitality and tourism, management, publishing, and nursing. The contributors acknowledge ChatGPT’s capabilities to enhance productivity and suggest that it is likely to offer significant gains in the banking, hospitality and tourism, and information technology industries, and enhance business activities, such as management and marketing. Nevertheless, they also consider its limitations, disruptions to practices, threats to privacy and security, and consequences of biases, misuse, and misinformation. However, opinion is split on whether ChatGPT’s use should be restricted or legislated. Drawing on these contributions, the article identifies questions requiring further research across three thematic areas: knowledge, transparency, and ethics; digital transformation of organisations and societies; and teaching, learning, and scholarly research. The avenues for further research include: identifying skills, resources, and capabilities needed to handle generative AI; examining biases of generative AI attributable to training datasets and processes; exploring business and societal contexts best suited for generative AI implementation; determining optimal combinations of human and generative AI for various tasks; identifying ways to assess accuracy of text produced by generative AI; and uncovering the ethical and legal issues in using generative AI across different contexts.

During the past two decades, the public health community's attention has been drawn increasingly to the social determinants of health (SDH)-the factors apart from medical care that can be influenced by social policies and shape health in powerful ways. We use "medical care" rather than "health care" to refer to clinical services, to avoid potential confusion between "health" and "health care." The World Health Organization's Commission on the Social Determinants of Health has defined SDH as "the conditions in which people are born, grow, live, work and age" and "the fundamental drivers of these conditions." The term "social determinants" often evokes factors such as health-related features of neighborhoods (e.g., walkability, recreational areas, and accessibility of healthful foods), which can influence health-related behaviors. Evidence has accumulated, however, pointing to socioeconomic factors such as income, wealth, and education as the fundamental causes of a wide range of health outcomes. This article broadly reviews some of the knowledge accumulated to date that highlights the importance of social-and particularly socioeconomic-factors in shaping health, and plausible pathways and biological mechanisms that may explain their effects. We also discuss challenges to advancing this knowledge and how they might be overcome.

BACKGROUND: The quality and quantity of individuals' social relationships has been linked not only to mental health but also to both morbidity and mortality. OBJECTIVES: This meta-analytic review was conducted to determine the extent to which social relationships influence risk for mortality, which aspects of social relationships are most highly predictive, and which factors may moderate the risk. DATA EXTRACTION: Data were extracted on several participant characteristics, including cause of mortality, initial health status, and pre-existing health conditions, as well as on study characteristics, including length of follow-up and type of assessment of social relationships. RESULTS: Across 148 studies (308,849 participants), the random effects weighted average effect size was OR = 1.50 (95% CI 1.42 to 1.59), indicating a 50% increased likelihood of survival for participants with stronger social relationships. This finding remained consistent across age, sex, initial health status, cause of death, and follow-up period. Significant differences were found across the type of social measurement evaluated (p<0.001); the association was strongest for complex measures of social integration (OR = 1.91; 95% CI 1.63 to 2.23) and lowest for binary indicators of residential status (living alone versus with others) (OR = 1.19; 95% CI 0.99 to 1.44). CONCLUSIONS: The influence of social relationships on risk for mortality is comparable with well-established risk factors for mortality. Please see later in the article for the Editors' Summary.

The global burden of cancer continues to increase largely because of the aging and growth of the world population alongside an increasing adoption of cancer-causing behaviors, particularly smoking, in economically developing countries. Based on the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths are estimated to have occurred in 2008; of these, 56% of the cases and 64% of the deaths occurred in the economically developing world. Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among females, accounting for 23% of the total cancer cases and 14% of the cancer deaths. Lung cancer is the leading cancer site in males, comprising 17% of the total new cancer cases and 23% of the total cancer deaths. Breast cancer is now also the leading cause of cancer death among females in economically developing countries, a shift from the previous decade during which the most common cause of cancer death was cervical cancer. Further, the mortality burden for lung cancer among females in developing countries is as high as the burden for cervical cancer, with each accounting for 11% of the total female cancer deaths. Although overall cancer incidence rates in the developing world are half those seen in the developed world in both sexes, the overall cancer mortality rates are generally similar. Cancer survival tends to be poorer in developing countries, most likely because of a combination of a late stage at diagnosis and limited access to timely and standard treatment. A substantial proportion of the worldwide burden of cancer could be prevented through the application of existing cancer control knowledge and by implementing programs for tobacco control, vaccination (for liver and cervical cancers), and early detection and treatment, as well as public health campaigns promoting physical activity and a healthier dietary intake. Clinicians, public health professionals, and policy makers can play an active role in accelerating the application of such interventions globally.

This essay incorporates a general treatment of social interactions into the modern theory of consumer demand. Section 1 introduces the topic and explores some of the existing perspectives on social interactions and their importance in the basic structure of wants. In Section 2, various characteristics of different persons are assumed to affect the utility functions of some persons, and the behavioral implications are systematically explored. Section 3 develops further implications and applications in the context of analyzing intra-family relations, charitable behavior, merit goods and multi-persons interactions, and envy and hatred. The variety and significance of these applications is persuasive testimony not only to the importance of social interactions, but also to the feasibility of incorporating them into a rigorous analysis.

The use of the internet and social media have changed consumer behavior and the ways in which companies conduct their business. Social and digital marketing offers significant opportunities to organizations through lower costs, improved brand awareness and increased sales. However, significant challenges exist from negative electronic word-of-mouth as well as intrusive and irritating online brand presence. This article brings together the collective insight from several leading experts on issues relating to digital and social media marketing. The experts’ perspectives offer a detailed narrative on key aspects of this important topic as well as perspectives on more specific issues including artificial intelligence, augmented reality marketing, digital content management, mobile marketing and advertising, B2B marketing, electronic word of mouth and ethical issues therein. This research offers a significant and timely contribution to both researchers and practitioners in the form of challenges and opportunities where we highlight the limitations within the current research, outline the research gaps and develop the questions and propositions that can help advance knowledge within the domain of digital and social marketing.

ABSTRACT If we are to develop better methods of integrating elderly people into society then above all we need a better sociology of the ageing and the aged. In this paper I wish to put forward the thesis that the dependency of the elderly in the twentieth century is being manufactured socially and that its severity is unnecessary. The process can therefore be revised or at least modified. Certain major influences, which will be discussed below, are steadily deepening, or widening that dependency. There is the imposition, and acceptance, of earlier retirement; the legitimation of low income; the denial of rights to self-determination in institutions; and the construction of community services for recipients assumed to be predominantly passive.
