ABSTRACT Long term problems associated with future immunological methods of fertility control include the following: (1) reversibility, (2) unscrupulous use, (3) unphysiological intervention giving rise, among other possibilities, to carcinogenesis, (4) deleterious genetical selection operating on antigens, and (5) deleterious genetical selection operating on the immune response. The first three of these constitute a hazard to individuals, and the last two to populations. None is considered to constitute a threat so serious as to inhibit further research on the subject. We should keep under review future developments in relevant areas of immunology, including particularly cell-cell cooperation as a mechanism in autoimmunity, and immune response genes as the objects of immunoselection. It will be important also to come to terms with the social, political, and economic consequences of any cheap, widely-applicable form of birth control, such as might develop from immunological research. The possibility is raised of wide-spread immunisation against a synthetic immunological determinant, as an aid to fertility control. Another possibility is to make women grandchildless.

The rise of the Internet has spawned the prolific use of the adjective “virtual.” Both the popular press and scholarly researchers have written about virtual work, virtual teams, virtual organizations, and virtual groups. But perhaps one of the most interesting phenomena to come to the forefront has been that of virtual communities. Many definitions of this term have been proposed and the term has been used in many different ways. This article will examine some of the most popular definitions and guidelines to understand what truly constitutes a virtual community. To define a virtual community, one needs to first examine the two words separately, particularly the sociological definition of “community.” The German sociologist Ferdinand Tonnies, in his 1887 book, made the distinction between two basic types of social groups: Gemeinschaft (community) and Gesellschaft (society). The former was often exemplified by the family or neighborhood (Tonnies, 1957). Sociology literature also often refers to the definition given by George Hillery, who reviewed 94 different definitions in academic studies. Three elements were common to the definitions, namely that community (1) was based on geographic areas, (2) included social interaction among people, and (3) had common ties such as social life, norms, means, or ends (Hillery, 1955). Thus the term community typically connotes a group of people within some geographic boundary, such as a neighborhood, or perhaps smaller subsection of a larger city. Further specification might have defined a community as a group of people within the geographic boundary with a common interest, such as the Jewish community of Brooklyn or the physician community of London. Therefore, members of the community were drawn together by both local proximity and common interest, even if the interest was in the geographic area itself. The term virtual, precipitated by the advent of information technology, and specifically, the Internet, means without a physical place as a home (Handy, 1995), or that which is electronic or enabled by technology (Lee, Vogel, & Limayem, 2003). Information technology therefore has expanded the means by which the social interaction in communities can be accomplished. While for most of human existence interaction was strictly limited to the face-to-face medium, social interaction can now be accomplished virtually, thus eliminating the necessity of being physically close enough to communicate. This type of communication is called computer-mediated communication (CMC). Combining the two terms together, thus, would mean eliminating the geographic requirements and allowing that the social interaction would occur virtually, that is, via information technology, among people with common ties. In fact, people have been coming together in virtual communities on the Internet for over 25 years. Usenet newsgroups, started in 1979, are widely regarded as the first virtual communities on the Internet (M. A. Smith, 1999), and The Well (www.well.com), started in 1985, is often referred to as an early exemplar of virtual community (Rheingold, 1993). Virtual communities may be part of a long-term shift away from geographic ties to common interest ties (Wellman & Gulia, 1999b). Formal definitions and understandings of the term virtual community still remain problematic, however (Lee et al., 2003). Perhaps the most cited definition is that of Howard Rheingold, a prominent author, consultant, and member of The Well: Social aggregations that emerge from the Net when enough people carry on those public discussions long enough, with sufficient human feeling, to form webs of personal relationships in cyberspace. (Rheingold, 1993, p. 5) Common to many of the definitions is the presence of shared interests or goals (Dennis, Pootheri, & Natarajan, 1998; Figallo, 1998; Kilsheimer, 1997). With the advent of information technology, locating/contacting others outside the local community has become relatively easy, especially when one seeks others who have a unique or uncommon interest. It may be that technology makes it easier for communities to form. For example, it may be difficult for someone interested in traditional bowhunting to locate others with the same inclinations by popping into the local tavern or socializing at a church function. However, a simple search in Google reveals a vibrant community centered around such an interest (www.bowsite.com/). There are virtual communities for nearly every interest that comes to mind, from medical afflictions (e.g., breast cancer, Parkinson’s, Down’s syndrome) to hobbies (e.g., coin collecting, wine, saltwater aquariums) to professions (e.g., nursing, law, finance). Implicit with the notion of community is some permanence among members and frequency of visits by members (A. D. Smith, 1999). Virtual communities must have a sense of long-term interaction (Erickson, 1997), not a place where people go only occasionally or where there are always different people. It is not uncommon for people to develop strong attachments to virtual communities, visiting them often enough to be described as “addicted” (Hiltz, 1984; Hiltz & Wellman, 1997). The members often feel part of a larger social whole within a web of relationships with others (Figallo, 1998). Indeed, many researchers have considered virtual communities as social networks (Hiltz & Wellman, 1997; Wellman, 1996; Wellman & Gulia, 1999a). Ridings et al. (2002) offer a comprehensive definition that incorporates the afore-mentioned concepts: Groups of people with common interests and practices that communicate regularly and for some duration in an organized way over the Internet through a common location or mechanism.

This chapter examines the foundational forces that shape health. Even without a pandemic, the United States is faced with public health threats that are shaped by foundational forces. From the political and economic roots of the obesity epidemic, to the social stigma that informs the opioid crisis, to the many structural drivers of climate change, the social, economic, political, and demographic foundations of health are central to the challenges that must be addressed, nationally and globally, in the years to come. Engaging with these forces helped inform the response to COVID-19; they can help in addressing these other challenges as well. And just as a virus can have long-term effects on the body, the pandemic reshaped the societal foundations, with lasting implications for the economy, culture, attitudes towards core issues like race, politics, and more. Whether the experience of the pandemic leads to significant long-term benefits will depend on whether Americans retain the hard lessons of that moment and apply them to foundational forces.

Purpose – The purpose of this paper is to explore common usage and understanding of the term “frailty”, which is increasingly used in health care debates in England. Design/methodology/approach – This is a commentary from the perspectives of health and social care researchers. Recent policy and research are drawn upon in the arguments presented. Findings – Most research on the subject of frailty comes from clinical practice although a parallel sociological or gerontological critique of the social construction is emerging. The public is likely to come across the term frailty through the media’s adoption of the term. Different definitions of frailty mean that estimates of the numbers of “frail people” will vary. Research limitations/implications – The commentary draws on material in the English language and on policy, commentary, and research material. Practical implications – The commentary may prompt reflection in practice and policy development on the usage of the term frailty and promote efforts to ensure that its meaning is clear and that it is acceptable to those to whom it is applied. Originality/value – The paper contributes to debates about frailty by considering the implications of using the term across health and social care and in integrated settings and encounters. It draws on medical presentations of the term frailty and on critiques of it as a powerful discourse.

This research note contributes to the emerging debate on the consequences of the COVID-19 pandemic for democracy, autocracy and regime change. Following a review of the literature on the short-term impact of the pandemic on citizen freedoms, I conduct a preliminary test showing that COVID-19 has widened the freedom divide between democracy and autocracy. I propose a prudential interpretation of this new finding and of its implications for medium- to long-term regime change dynamics. In an age of advancing autocratization, regaining awareness that democracies and autocracies treat citizens differently could help marginalize antisystem political forces in democratic countries. However, increased levels of repression in regimes that are already authoritarian are no good news in terms of prospective democratization. Moreover, the management of the social and economic consequences of the pandemic is likely to represent a key driver of future regime change, duo to its impact on the legitimacy and stability of both democracies and autocracies.

This chapter introduces the book as a whole. It explains the subject of interest—change in assets in rural areas. It also explains the methods used to examine them: longitudinal studies—revisits to previously surveyed villages and domestic units. It also outlines the argument. This is that contra to critics of smallholder farmers who decry their lack of activity and critics of neoliberal economic policies for the poverty they cause, the authors have found, surprisingly, that there is more wealth, in terms of assets than they were expecting to find. The chapter explains how the authors selected their study sites and presents brief summaries of each case and the chapters to come.

Beat reporting refers to thematic specialization and routines (places to go, people to see) in journalism. The term reflects the distinction between general assignment reporters and specialized (beat) reporters covering a specific area (beat) as well as the subject-matter or geographic divisions between areas of reporting by which media organizations seek to structure the social environment they cover. Beat reporting marks the beginning of modern journalism. It was invented at the end of the 19th century in the United States with the aim to increase the efficiency of journalistic work. Thus it relates to the professionalization and rationalization of newspaper journalism and the transformation of newspapers into a mass product. In everyday work, beat reporting has undeniable advantages. It saves resources since beat reporters are very experienced on their beat and know well where and how to get exactly the information they need. Due to their long-term relationship of trust with relevant sources, beat reporters obtain exclusive, trustworthy, and newsworthy information. Along with this specialization come, however, several challenges; for example, the diversity of views represented in a beat might be limited, which can also affect the diversity of news coverage. At the extreme, this can even lead to pack journalism as a form of groupthink. Concerning the reporter–source relationship, there are three risks of losing professional distance: (a) If beat reporters become too loyal toward their sources, they can be instrumentalized; (b) being too adversarial toward their sources might entail a loss of trust and an increasing cynicism of the audience; (c) if beat reporters start feeling like advocates of their own interests, they might behave as activists rather than detached observers. Most recently, online journalism has changed the understanding of beat journalism (e.g., data journalism, local online beat) compared to the traditional understanding. Research on beat journalism has so far focused on stable, high-income democracies and on the political beat as the most fundamental and prominent beat.

O construto autoeficácia está relacionado às crenças desenvolvidas pelos indivíduos em relação às ações que confiam poder realizar com sucesso em áreas específicas. É também de grande relevância nos processos de autorregulação dos sujeitos, sendo tais conceitos analisados em diferentes contextos, dentre eles o ambiente educacional, com o propósito de avaliar o comportamento dos estudantes diante dos desafios escolares. A evasão escolar é outro importante aspecto que merece destaque nos processos de avaliação institucional na área de educação, em virtude das consequências sociais, acadêmicas e econômicas. Assim, o presente estudo objetivou investigar conceitos referentes à autoeficácia e à autorregulação acadêmica, a fim de verificar se esses fatores contribuem para prever a evasão escolar, e auxiliar no planejamento de intervenções que possibilitem minimizar a evasão dos alunos. As análises indicaram que tanto a autoeficácia quanto a autorregulação acadêmica tratam-se de variáveis significativas, sendo que, do ponto de vista teórico, representam importantes preditores para a evasão dos estudantes. Portanto, o propósito da pesquisa foi alcançado, mas devido às limitações deste estudo que se baseou apenas em fontes bibliográficas, recomenda-se a realização de novas investigações que contemplem pesquisas de campo em diferentes instituições de ensino, a fim de aprofundar a compreensão sobre o assunto. Palavras-chave: Autoeficácia. Autorregulação Acadêmica. Evasão Escolar. SELF-EFFICACY AND ACADEMIC SELF-REGULATION CONTRIBUTING TO PREDICTIONOF THE ESCOLAR EVASION Abstract: The self-efficacy construct is related to beliefs developed by individuals in relation to the actions that trust can perform successfully in specific areas, it is also of great importance in the processes of academic self-regulation of the people, these concepts have been analyzed in different contexts, including the environment educational, in order to evaluate the behavior of students facing school challenges. The school evasion is another important aspect that deserves attention in institutional assessment processes in the education area, because of the social, academic and economic consequences. Thus, the present study aimed to investigate concepts related to self-efficacy and academic self-regulation to verify if these factors contribute to predict school evasion, and assist in planning interventions that enable minimize the evasion of the students. The analysis indicated that both self-efficacy and academic self-regulation are significant variables, and the theoretical point of view is important predictor for school evasion. Therefore, the purpose of the study was achieved, but due to the limitations of this study that was based only on literature sources, it is recommended to conduct further investigations that include field research in different educational institutions, to deepen understanding about the subject. Keywords: Self-Efficacy. Academic Self-Regulation. School Evasion.

The conservation community is increasingly focusing on the monitoring and evaluation of management, governance, ecological, and social considerations as part of a broader move toward adaptive management and evidence‐based conservation. Evidence is any information that can be used to come to a conclusion and support a judgment or, in this case, to make decisions that will improve conservation policies, actions, and outcomes. Perceptions are one type of information that is often dismissed as anecdotal by those arguing for evidence‐based conservation. In this paper, I clarify the contributions of research on perceptions of conservation to improving adaptive and evidence‐based conservation. Studies of the perceptions of local people can provide important insights into observations, understandings and interpretations of the social impacts, and ecological outcomes of conservation; the legitimacy of conservation governance; and the social acceptability of environmental management. Perceptions of these factors contribute to positive or negative local evaluations of conservation initiatives. It is positive perceptions, not just objective scientific evidence of effectiveness, that ultimately ensure the support of local constituents thus enabling the long‐term success of conservation. Research on perceptions can inform courses of action to improve conservation and governance at scales ranging from individual initiatives to national and international policies. Better incorporation of evidence from across the social and natural sciences and integration of a plurality of methods into monitoring and evaluation will provide a more complete picture on which to base conservation decisions and environmental management.
