Social Trait

AbstractBacterial cooperation can be disrupted by non-producers, which can profit from public goods without paying their production cost. A cheater can increase in frequency, exhausting the public good and causing a population collapse. Here we investigate how interactions among two cheaters for distinct social traits influence the short and long-term dynamics of polymorphic populations. Using as a modelPseudomonas aeruginosaand its extensively studied social traits, production of the siderophore pyoverdine and the quorum sensing regulated elastase, we analyzed the social dynamics of polymorphic populations under conditions where the two traits are required for optimal growth. We show that cheaters for either trait compete with both the wild type and each other, and that mutants for pyoverdine production can prevent a drastic population collapse caused by quorum sensing cheaters. A simple mathematical model suggests that the observed social dynamics are determined by the ratio of the costs of each social trait, such that the mutant which avoids paying the highest cost dominates the population. Finally, we demonstrate how quorum sensing regulation can avoid the full loss of cooperation.

Reflection about the role of community engagement and corporate social investment in Brazil, associated with the presence of a large economic enterprise, is the major stimulus of this chapter. It seeks to present how cross-sector governance can contribute to the social development of a city and how this process can be led by a partnership comprising a corporate foundation, government, and civil society. The concept of the public–private social partnership (PPSP) is explored: a strategy for building a series of inter-sectoral alliances aimed at promoting the sustainable development of territories where the company has large-scale enterprises, through joint efforts towards integrated long-term strategic planning, around a common agenda. To this end, the case of Canaã dos Carajás is introduced, a municipality in the State of Pará, in the Amazon region, where large-scale mining investment is being carried out by the mining company Vale SA.

Complicated Nature

The economy of Southeast Asia has been in relatively good shape in spite of the instability of the world monetary system, trade deficits, and the worldwide oil crisis. There are promising factors for economic growth, opportunities for employment, and possibilities of rising income. But Asian development presents short-and long-term problems of a very complicated nature. One of the most serious problems is inflation and its impact on the social and political programs of individual countries. At the same time, there are severe shortages of basic commodities, such as oil and food. My own country, Japan, is among those affected.

Added Benefit

Citizen science is known for increasing the geographic, spatial, and temporal scale from which scientists can gather data. It is championed for its potential to provide experiential learning opportunities to the public. Documentation of educational outcomes and benefits for citizen scientists continues to grow. This study proposes an added benefit of these collaborations: the transference of program impacts to individuals outside of the program. The experiences of fifteen citizen scientists in entomology citizen science programs were analyzed using a constructivist grounded theory methodology. We propose the substantive-level theory of transference to describe the social process by which the educational and attitudinal impacts intended by program leaders for the program participants are filtered by citizen scientists and transferred to others. This process involves individual and external phases, each with associated actions. Transference occurred in participants who had maintained a long-term interest in nature, joined a citizen science program, shared science knowledge and experiences, acquired an expert role to others, and influenced change in others. Transference has implications for how citizen scientists are perceived by professional communities, understanding of the broader impacts and contributions of citizen science to wicked problems, program evaluation, and the design of these programs as informal science education opportunities.

The aim of the study is an historical analysis of the work undertaken by the Public Health organizations dedicated to the combat of the Aedes aegypti, as well as an epidemiolocal study of persons with unexplained fever, with a view to evaluating the ocurrence of dengue within the population. The Mac-Elisa, Gac-Elisa, hemaglutination inhibition, isolation and typage tests were used. Organophosphate intoxication in agricultural workers was also assessed by measuring concentrations of serie cholinesterase. A sera samples of 2,094 were collected in 23 towns, and the type 1 dengue virus was detected in 17 towns and autochthony was confirmed in 12 of them. The cholinesterase was measured in 2,391 sera samples of which 53 cases had abnormal levels. Poisoning was confirmed in 3 cases. Results reveal an epidemic the gravity of which was not officially know. The relationshipe between levels of IgM and IgG antibodies indicates the outbreak tendency. The widespread distribution of the vector is troubling because of the possibility of the urbanization of wild yellow fever, whereas the absence of A. aegypti in 2 towns with autochthony suggests the existence of another vector. Since there is no vaccine against dengue, the combat of the vector is the most efficient measure for preventing outbreaks. The eradication of the vector depends on government decisions which depend, for their execution, on the organization of the Health System and the propagation of information concerning the prevention of the disease using all possible means because short and long term results depend on the education and the active participation of the entire population.

Resumo: O cenário de instabilidade política, a recessão econômica e as mudanças nas regras de concessão de crédito pautaram o objetivo de examinar o relacionamento do crédito consignado, por segmento de concessão, com variáveis macroeconômicas, caso do consumo, da produção industrial e do produto agregado, na última década (2007-2017). Os resultados foram obtidos por meio da estimação do vetor de correção de erros, funções de impulso-resposta e decomposição da variância, possibilitando a análise das relações de curto e de longo prazo entre as séries temporais e indicaram que as diferentes modalidades do crédito consignado implicam efeitos distintos sobre as variáveis econômicas em curto prazo. O segmento de aposentados e pensionistas impacta positivamente ambas as variáveis analisadas, com destaque para os bens de consumo das famílias. Já a concessão ao setor privado, embora represente a menor parcela do crédito consignado concedido, mostrou elevada sensibilidade a alterações na oferta dessa modalidade de crédito, enquanto que o crédito ao setor público, de maior participação, apresentou efeitos reduzidos e de curta duração.Palavras-chave: Crédito consignado.

The results obtained by error correction vector estimation, and functions of impulse-response and variance decomposition, making it possible to analyze the short- and long-term relationships between the time series and indicated that the different modalities of payroll loans imply different effects on economic short-term variables. With retirees and pensioners segment positively impact on both analyzed variables, highlighting the household consumption goods. The concession to the private sector, although it represents the smallest portion of payroll loans granted, it showed high sensitivity to the changes of this modality. About credit to the public sector, which has the biggest portion, it showed reduced and short-term effects.Keywords: Payroll loans. Segments. Brazilian economy.

Systematic Framework

Wicked consumption behavior, namely the inflated consumption of unhealthy commodities such as tobacco and soft drinks, constitutes a leading risk for noncommunicable diseases including cancer and diabetes. Despite the fatal impact of wicked consumption on societal welfare, both the social marketing literature and the public policy literature lack a systematic framework capturing the unfolding of the wicked consumption cycle and providing guidance on when and how to intervene upstream. Drawing on historical data on tobacco and soft drink consumption in the U.S., we propose a four-stage epidemic life cycle of wicked consumer behavior. The biological and habitual factors that make different types of wicked consumption appealing to consumers are reinforced by the marketing activities of the manufacturers. To overcome the strong resistance posed by habitual wicked consumption, we articulate a typology of upstream intervention parameters and provide guidance on when and how to intervene depending on the desired long-term equilibrium.

Practical Implications

Purpose While the COVID-19 virus has been spreading worldwide, some studies have related the pandemic with various aspects of accounting and therefore emphasized the importance of accounting research in understanding the impact of COVID-19 on society as a whole. Recent studies have looked into such an impact on various industries such as retail and agriculture. The current study aims at applying a sociological framework, sociology of worth (SOW), to the gaming industry in Macau, the largest operator of state-allowed gambling and entertainment in China, which will allow for its development during the COVID-19 pandemic to be charted. Design/methodology/approach The study uses the theory of SOW as a framework and collects data from various sources, such as the government, gaming operators and the public, to create timelines and SOW frameworks to analyze the impact of the virus on the gaming industry and the society as a whole. Findings Detailed content analysis and the creation of different SOW matrices determined that the notion of a “lonely economy” during a time of a critical event may be ameliorated in the long term through compromises of the different worlds and actors of the SOW. Practical implications Though largely theory-based, this study offers a thorough account of the COVID-19 incident for both the government and the gaming industry to reflect on and to consider new ways to fight against degrowth caused by disasters or crises. Social implications The SOW framework divides society into different worlds of different worths. The current study shows how the worths of the different worlds are congruent during normal periods, and how cracks appear between them when a sudden crisis, such as COVID-19, occurs. The article serves as a social account of how these cracks are formed and how could they be resolved through compromise and reconstruction. Originality/value This study is a first attempt to apply SOW to a controversial industry (gaming) while the effects of the COVID-19 pandemic are ongoing. It offers a significant contribution to the social accounting literature through its consideration of the combination of unprecedented factors in a well-timed study that pays close attention to analyses and theoretical elaboration.

Ecological Science

There are many precedents for long-term research in the history of science. Long-Term Ecological Research (LTER) program’s current identity reflects significant change—intended and accidental, both consensual and conflictual—from research concerns that were prevalent in the 1980s. LTER program has pioneered modes of research organization and professional norms that are increasingly prominent in many areas of research and that belong to a significant transformation in the social relations of scientific research. The essays in this volume explore the impact of the LTER program, a generation after its founding, on both the practice of ecological science and the careers of scientists. The authors have applied the agenda of long- term scrutiny to their own careers as LTER researchers. They have recognized the LTER program as distinct, even perhaps unique, both in the ways that it creates knowledge and in the ways that it shapes careers. They have reflected on how they have taught (and were taught) in LTER settings, on how they interact with one another and with the public, and on how research in the LTER program has affected them “as persons.” A rationale for this volume is LTER’s distinctiveness. In many of the chapters, and in other general treatments of the LTER program, beginning with Callahan (1984), one finds a tone of defensiveness. Sometimes the concerns are explicit: authors (e.g., Stafford, Knapp, Lugo, Morris; Chapters 5, 22, 25, 33, respectively) bemoan colleagues who dismiss LTER as mere monitoring instead of serious science or who resent LTER’s independent funding stream. But more broadly, there is concern that various groups, ranging from other bioscientists to the public at large, may not appreciate the importance of long-term, site-specific environmental research. Accordingly, my hope here is to put LTER into several broader contexts. I do so in three ways. First, to mainstream LTER within the history of science, I show that the LTER program is not a new and odd way of doing science but rather exemplifies research agendas that have been recognized at least since the seventeenth century in the biosciences and beyond.

Increasing public pressure on Canada's land resources to produce a greater variety of social values indicates an urgent need for integrated resources management. This, in turn, requires a reorientation in the traditional "single resource" thinking of foresters and others. However, it is believed that the current major impediments to developing integrated resource management are to be found in the attitudes and opinions which prevail in the administrative centres of government in respect to social, political, economic, legal, and other matters. Integrated resource management is fundamentally a social concept and a prerequisite to long-term progress in this area is a better knowledge and awareness of the social-environmental needs of society on the part of all resource personnel. Foresters are closely identified in the public mind with responsibilities in wildland management and should be actively concerned with integrated resource management.

European universities responded in different ways to the ‘refugee crisis’ of 2015. Some subscribed to the agenda of higher education (HE) as a universal human right, while others stressed different long-term benefits of offering access to it. Yet, the unprecedented sense of moral urgency that guided immediate declarations of support and subsequent actions has largely remained unaddressed. With the crisis becoming a new reality for many countries, HE has a role to play in the social inclusion of refugees, even in countries that were not attractive destinations for refugees in the past. In this article, we provide an overview of the reasons why HE institutions supported refugees, and present the results of an empirical study of Poland and Austria during the 2015–2016 academic year. We then evaluate those first responses utilizing parts of Ager and Strang’s framework of integration, and discuss issues of institutional readiness, capabilities and the public role of HE stemming from this comparison. Our findings suggest that reasons such as acknowledgement of basic rights, or utilizing social capital are insufficient to explain and understand strong integrative support measures. We propose that refugee support by HE institutions is both better understood and promoted through the language of hospitality.
