  1. A Global Public Goods Approach to the Health of Migrants

    Widdows, Heather; Marway, Herjeet

    2015-01-01

    This paper explores a global public goods approach to the health of migrants. It suggests that this approach establishes that there are a number of health goods which must be provided to migrants not because these are theirs by right (although this may independently be the case), but because these goods are primary goods which fit the threefold criteria of global public goods. There are two key advantages to this approach: first, it is non-confrontational and non-oppositional, and second, it provides self-interested arguments to provide at least some health goods to migrants and thus appeals to those little moved by rights-based arguments.

    2001-01-01

    We examined recent special health initiatives to control HIV/AIDS, malaria, and tuberculosis, and make four policy recommendations for improving the sustainability of such initiatives. First, international cooperation on health should be seen as an issue of global public goods that concerns both poor and rich countries. Second, national health and other sector budgets should be tapped to ensure that global health concerns are fully and reliably funded; industrialized countries should lead the way. Third, a global research council should be established to foster more efficient health-related knowledge management. Fourth, managers for specific disease issues should be appointed, to facilitate policy partnerships. Policy changes in these areas have already begun and can provide a basis for further reform.

  3. The global public good concept: a means of promoting good veterinary governance.

    PubMed

    Eloit, M

    2012-08-01

    At the outset, the concept of a 'public good' was associated with economic policies. However, it has now evolved not only from a national to a global concept (global public good), but also from a concept applying solely to the production of goods to one encompassing societal issues (education, environment, etc.) and fundamental rights, including the right to health and food. Through their actions, Veterinary Services, as defined by the Terrestrial Animal Health Code (Terrestrial Code) of the World Organisation for Animal Health (OIE), help to improve animal health and reduce production losses. In this way they contribute directly and indirectly to food security and to safeguarding human health and economic resources. The organisation and operating procedures of Veterinary Services are therefore key to the efficient governance required to achieve these objectives. The OIE is a major player in global cooperation and governance in the fields of animal and public health through the implementation of its strategic standardisation mission and other programmes for the benefit of Veterinary Services and OIE Member Countries. Thus, the actions of Veterinary Services and the OIE deserve to be recognised as a global public good, backed by public investment to ensure that all Veterinary Services are in a position to apply the principles of good governance and to comply with the international standards for the quality of Veterinary Services set out in the OIE Terrestrial Code (Section 3 on Quality of Veterinary Services) and Aquatic Animal Health Code (Section 3 on Quality of Aquatic Animal Health Services).

    Since at least the 1990s, there has been growing recognition that societies need global public goods (GPGs) in order to protect and promote public health. While the term GPG is sometimes used loosely to denote that which is 'good' for the global public, we restrict our use of the term to its technical definition (goods that are non-excludable and non-rival in consumption) for its useful analytical clarity. Examples of important GPGs for health include standards and guidelines, research on the causes and treatment of disease, and comparative evidence and analysis. While institutions for providing public goods are relatively well developed at the national level - being clearly recognized as a responsibility of sovereign states - institutional arrangements to do so remain fragmented and thin at the global level. For example, the World Health Organization, mandated to provide many GPGs, is not appropriately financed to do so. Three steps are needed to better govern the financing and provision of GPGs for health: first, improved data to develop a clearer picture of how much money is currently going to providing which types of GPGs; second, a legitimate global political process to decide upon priority missing GPGs, followed by estimates of total amounts needed; and third, financing streams for GPGs from governments and private sources, to be channeled through new or existing institutions. Financing should go toward fully financing some GPGs, complementing or supplementing existing national or international financing for others, or deploying funds to make potential GPGs less 'excludable' by putting them into the public domain. As globalization deepens the degree of interdependence between countries and as formerly low-income economies advance, there may be less relative need for development assistance to meet basic health care needs, and greater relative need to finance GPGs. Strengthening global arrangements for GPGs today is a worthy investment for improved global

  5. Global public goods and the global health agenda: problems, priorities and potential

    2007-01-01

    The 'global public good' (GPG) concept has gained increasing attention, in health as well as development circles. However, it has suffered in finding currency as a general tool for global resource mobilisation, and is at risk of being attached to almost anything promoting development. This overstretches and devalues the validity and usefulness of the concept. This paper first defines GPGs and describes the policy challenge that they pose. Second, it identifies two key areas, health R&D and communicable disease control, in which the GPG concept is clearly relevant and considers the extent to which it has been applied. We point out that that, while there have been many new initiatives, it is not clear that additional resources from non-traditional sources have been forthcoming. Yet achieving this is, in effect, the entire purpose of applying the GPG concept in global health. Moreover, the proliferation of disease-specific programs associated with GPG reasoning has tended to promote vertical interventions at the expense of more general health sector strengthening. Third, we examine two major global health policy initiatives, the Global Fund against AIDS, Tuberculosis and Malaria (GFATM) and the bundling of long-standing international health goals in the form of Millennium Development Goals (MDG), asking how the GPG perspective has contributed to defining objectives and strategies. We conclude that both initiatives are best interpreted in the context of traditional development assistance and, one-world rhetoric aside, have little to do with the challenge posed by GPGs for health. The paper concludes by considering how the GPG concept can be more effectively used to promote global health. PMID:17888173

    2004-05-01

    Genomics, the comprehensive examination of an organism's entire set of genes and their interactions, will have a major impact on the way disease is diagnosed, prevented and treated in the new millennium. Despite the tremendous potential it holds for improving global health, genomics challenges policy-makers to ensure that its benefits are harnessed equitably across populations and nations. The classification of genomics as a global public good and the inequity encountered in the development and application of genomics knowledge are outlined in this paper, We examine the effect of the current patent system on the distribution of costs and benefits relating to genomics knowledge between countries of different economic strength. The global public goods concept provides a normative economic rationale for the modification of certain aspects of the current patent system and for the creation of complementary mechanisms to respond to the health needs of low-income and middle-income countries.

  7. Is international agricultural research a global public good? The case of rice biofortification.

    PubMed

    Brooks, Sally

    2011-01-01

    The status of international agricultural research as a global public good (GPG) has been widely accepted since the Green Revolution of the 1960s and 1970s. While the term was not used at the time of its creation, the Consultative Group on International Agricultural Research (CGIAR) system that evolved at that time has been described as a 'prime example of the promise, performance and perils of an international approach to providing GPGs'. Contemporary literature on international agricultural research as a GPG tends to support this view and focuses on how to operationalize the concept. This paper adopts a different starting point and questions this conceptualization of the CGIAR and its outputs. It questions the appropriateness of such a 'neutral' concept to a system born of the imperatives of Cold War geopolitics, and shaped by a history of attempts to secure its relevance in a changing world. This paper draws on a multi-sited, ethnographic study of a research effort highlighted by the CGIAR as an exemplar of GPG-oriented research. Behind the ubiquitous language of GPGs, 'partnership' and 'consensus', however, new forms of exclusion and restriction are emerging within everyday practice, reproducing North-South inequalities and undermining the ability of these programmes to respond to the needs of projected beneficiaries.

  8. Can Migration Health Assessments Become a Mechanism for Global Public Health Good?

    Wickramage, Kolitha; Mosca, Davide

    2014-01-01

    Migrant health assessments (HAs) consist of a medical examination to assess a migrant’s health status and to provide medical clearance for work or residency based on conditions defined by the destination country and/or employer. We argue that better linkages between health systems and migrant HA processors at the country level are needed to shift these from being limited as an instrument of determining non-admissibility for purposes of visa issuance, to a process that may enhance public health. The importance of providing appropriate care and follow-up of migrants who “fail” their HA and the need for global efforts to enable data-collection and research on HAs are also highlighted.

    In real situations, the value of public goods will be reduced or even lost because of external factors or for intrinsic reasons. In this work, we investigate the evolution of cooperation by considering the effect of depreciation of public goods in spatial public goods games on a square lattice. It is assumed that each individual gains full advantage if the number of the cooperators nc within a group centered on that individual equals or exceeds the critical mass (CM). Otherwise, there is depreciation of the public goods, which is realized by rescaling the multiplication factor r to (nc/CM)r. It is shown that the emergence of cooperation is remarkably promoted for CM > 1 even at small values of r, and a global cooperative level is achieved at an intermediate value of CM = 4 at a small r. We further study the effect of depreciation of public goods on different topologies of a regular lattice, and find that the system always reaches global cooperation at a moderate value of CM = G - 1 regardless of whether or not there exist overlapping triangle structures on the regular lattice, where G is the group size of the associated regular lattice.

  10. Toward a treaty on safety and cost-effectiveness of pharmaceuticals and medical devices: enhancing an endangered global public good

    Faunce, Thomas Alured

    2006-01-01

    • Expert evaluations of the safety, efficacy and cost-effectiveness of pharmaceutical and medical devices, prior to marketing approval or reimbursement listing, collectively represent a globally important public good. The scientific processes involved play a major role in protecting the public from product risks such as unintended or adverse events, sub-standard production and unnecessary burdens on individual and governmental healthcare budgets. • Most States now have an increasing policy interest in this area, though institutional arrangements, particularly in the area of cost-effectiveness analysis of medical devices, are not uniformly advanced and are fragile in the face of opposing multinational industry pressure to recoup investment and maintain profit margins. • This paper examines the possibility, in this context, of States commencing negotiations toward bilateral trade agreement provisions, and ultimately perhaps a multilateral Treaty, on safety, efficacy and cost-effectiveness analysis of pharmaceuticals and medical devices. Such obligations may robustly facilitate a conceptually interlinked, but endangered, global public good, without compromising the capacity of intellectual property laws to facilitate local product innovations.

    Faulkner, Larry R.

    2005-02-01

    At every turn now, one encounters sharply debated issues and important public policies that rest on chemical information. This is true in practically any arena where public interest intersects with the material world: health care practice and public health; energy; quality of air, water, and food; manufacturing standards and product liability; criminal justice; national and international security, including the defense against terrorism. The scale can be truly global, as in the case of the current debate over climate change, which extends into international efforts to regulate gaseous emissions. Sometimes the relevant chemical measurements and applicable theory are sound and their scope is appropriate to the policy; often they are inadequate and a policy or debate overreaches the analytical capability needed to support it. In the decades ahead, the issues with us today will become even more pressing and will drive a still greater reliance on analytical chemistry. This presentation will have four parts covering (a) illustrations of the impact of analytical chemistry on public debate and public policy, including instances where analytical capabilities actually gave rise to new issues and policies, (b) the manner in which chemical information is handled and understood in public debates, (c) areas of analytical chemistry that will be critical to sound public policy in the future, and (d) implications for the education of leaders and general citizens of modern societies.

  14. Religiosity as a public good.

    PubMed

    Sherlock, Richard

    2008-09-01

    Public Goods can be seen as one important way in which societies sustain themselves over time. These are part of the puzzle of the development of political order. Public goods like the rule of law are non-substractable and non-excludable . For economists the classic textbook examples are national defense and police protection. In this paper I argue that religiosity can function like police protection, a means of sustaining order through fear of punishment from a transcendent source. As a means of reducing defection from social norms it has a role to play as a public good. But religion cannot at the same time be seen as the source of such norms or dissention will undermine the very order that punishment seems to reinforce.

  15. Paying for international environmental public goods.

    PubMed

    Arriagada, Rodrigo; Perrings, Charles

    2011-11-01

    Supply of international environmental public goods must meet certain conditions to be socially efficient, and several reasons explain why they are currently undersupplied. Diagnosis of the public goods failure associated with particular ecosystem services is critical to the development of the appropriate international response. There are two categories of international environmental public goods that are most likely to be undersupplied. One has an additive supply technology and the other has a weakest link supply technology. The degree to which the collective response should be targeted depends on the importance of supply from any one country. In principle, the solution for the undersupply lies in payments designed to compensate local providers for the additional costs they incur in meeting global demand. Targeted support may take the form of direct investment in supply (the Global Environment Facility model) or of payments for the benefits of supply (the Payments for Ecosystem Services model).

  17. Going public: good scientific conduct.

    Meyer, Gitte; Sandøe, Peter

    2012-06-01

    The paper addresses issues of scientific conduct regarding relations between science and the media, relations between scientists and journalists, and attitudes towards the public at large. In the large and increasing body of literature on scientific conduct and misconduct, these issues seem underexposed as ethical challenges. Consequently, individual scientists here tend to be left alone with problems and dilemmas, with no guidance for good conduct. Ideas are presented about how to make up for this omission. Using a practical, ethical approach, the paper attempts to identify ways scientists might deal with ethical public relations issues, guided by a norm or maxim of openness. Drawing on and rethinking the CUDOS codification of the scientific ethos, as it was worked out by Robert K. Merton in 1942, we propose that this, which is echoed in current codifications of norms for good scientific conduct, contains a tacit maxim of openness which may naturally be extended to cover the public relations of science. Discussing openness as access, accountability, transparency and receptiveness, the argumentation concentrates on the possible prevention of misconduct with respect to, on the one hand, sins of omission-withholding important information from the public-and, on the other hand, abuses of the authority of science in order to gain publicity. Statements from interviews with scientists are used to illustrate how scientists might view the relevance of the issues raised.

    2009-01-01

    The production, consumption, and exploitation of common resources ranging from extracellular products in microorganisms to global issues of climate change refer to public goods interactions. Individuals can cooperate and sustain common resources at some cost or defect and exploit the resources without contributing. This generates a conflict of interest, which characterizes social dilemmas: Individual selection favors defectors, but for the community, it is best if everybody cooperates. Traditional models of public goods do not take into account that benefits of the common resource enable cooperators to maintain higher population densities. This leads to a natural feedback between population dynamics and interaction group sizes as captured by “ecological public goods.” Here, we show that the spatial evolutionary dynamics of ecological public goods in “selection-diffusion” systems promotes cooperation based on different types of pattern formation processes. In spatial settings, individuals can migrate (diffuse) to populate new territories. Slow diffusion of cooperators fosters aggregation in highly productive patches (activation), whereas fast diffusion enables defectors to readily locate and exploit these patches (inhibition). These antagonistic forces promote coexistence of cooperators and defectors in static or dynamic patterns, including spatial chaos of ever-changing configurations. The local environment of cooperators and defectors is shaped by the production or consumption of common resources. Hence, diffusion-induced self-organization into spatial patterns not only enhances cooperation but also provides simple mechanisms for the spontaneous generation of habitat diversity, which denotes a crucial determinant of the viability of ecological systems.

    Szolnoki, Attila; Chen, Xiaojie

    2015-10-01

    Leaving the joint enterprise when defection is unveiled is always a viable option to avoid being exploited. Although loner strategy helps the population not to be trapped into the tragedy of the commons state, it could offer only a modest income for nonparticipants. In this paper we demonstrate that showing some tolerance toward defectors could not only save cooperation in harsh environments but in fact results in a surprisingly high average payoff for group members in public goods games. Phase diagrams and the underlying spatial patterns reveal the high complexity of evolving states where cyclic dominant strategies or two-strategy alliances can characterize the final state of evolution. We identify microscopic mechanisms which are responsible for the superiority of global solutions containing tolerant players. This phenomenon is robust and can be observed both in well-mixed and in structured populations highlighting the importance of tolerance in our everyday life.

    Miller, Cassandra

    If you are interested in food science, looking for a meaningful career path, and are motivated by the desire to make a difference, you may find that a career working for the public good can be very rewarding. Often, such opportunities address issues of social responsibility, sustainability, public health, and/or economic development. Food scientists who choose this path typically have an interest in social and public health issues, and are usually driven by the achievement of some sort of social, health, or societal gain. As food science in itself is a very broad discipline, applying this knowledge for the public good can also take a variety of paths. Whether you're interested in manufacturing, food safety, nutrition, food policy, product development, quality control, marketing and sales, or any other discipline that makes up the diverse field of food science, various opportunities exist to make a difference to society.

    NASA Astrophysics Data System (ADS)

    Shi, Dong-Mei; Zhuang, Yong; Wang, Bing-Hong

    2012-02-01

    In this work, the depreciation effect of public goods is considered in the public goods games, which is realized by rescaling the multiplication factor r of each group as r‧=r( (β≥0). It is assumed that each individual enjoys the full profit r of the public goods if all the players of this group are cooperators. Otherwise, the value of public goods is reduced to r‧. It is found that compared with the original version (β=0), the emergence of cooperation is remarkably promoted for β>0, and there exist intermediate values of β inducing the best cooperation. Particularly, there exists a range of β inducing the highest cooperative level, and this range of β broadens as r increases. It is further presented that the variation of cooperator density with noise has close relations with the values of β and r, and cooperation at an intermediate value of β=1.0 is most tolerant to noise.

    In this work, the optional public goods games with punishment are studied. By adopting the approximate best response dynamics, a micro model is given to explain the evolutionary process. Simultaneously, the magnitude of rationality is also considered. Under the condition of bounded rationality which provides a light to interpret phenomena in human society, the model leads to two types of equilibriums. One is the equilibrium without punishers and the other is the equilibrium including only punishers and cooperators. In addition, the effects of rationality on equilibriums are briefly investigated.

    We investigate the evolution of cooperation with evolutionary public goods games based on finite populations, where four pure strategies: cooperators, defectors, punishers and loners who are unwilling to participate are considered. By adopting approximate best response dynamics, we show that the magnitude of rationality not only quantitatively explains the experiment results in [Nature (London) 425 (2003) 390], but also it will heavily influence the evolution of cooperation. Compared with previous results of infinite populations, which result in two equilibriums, we show that there merely exists a special equilibrium and the relevant high value of bounded rationality will sustain cooperation. In addition, we characterize that loner's payoff plays an active role in the maintenance of cooperation, which will only be warranted for the low and moderate values of loner's payoff. It thus indicates the effects of rationality and loner's payoff will influence the cooperation. Finally, we highlight the important result that the introduction of voluntary participation and punishment will facilitate cooperation greatly.

    2016-01-01

    Understanding the causal impact of beliefs on contributions in Threshold Public Goods (TPGs) is particularly important since the social optimum can be supported as a Nash Equilibrium and best-response contributions are a function of beliefs. Unfortunately, investigations of the impact of beliefs on behavior are plagued with endogeneity concerns. We create a set of instruments by cleanly and exogenously manipulating beliefs without deception. Tests indicate that the instruments are valid and relevant. Perhaps surprisingly, we fail to find evidence that beliefs are endogenous in either the one-shot or repeated-decision settings. TPG allocations are determined by a base contribution and beliefs in a one shot-setting. In the repeated-decision environment, once we instrument for first-round allocations, we find that second-round allocations are driven equally by beliefs and history. Moreover, we find that failing to instrument prior decisions overstates their importance.

    2007-10-22

    Voluntary participation in public goods games (PGGs) has turned out to be a simple but effective mechanism for promoting cooperation under full anonymity. Voluntary participation allows individuals to adopt a risk-aversion strategy, termed loner. A loner refuses to participate in unpromising public enterprises and instead relies on a small but fixed pay-off. This system leads to a cyclic dominance of three pure strategies, cooperators, defectors and loners, but at the same time, there remain two considerable restrictions: the addition of loners cannot stabilize the dynamics and the time average pay-off for each strategy remains equal to the pay-off of loners. Here, we introduce probabilistic participation in PGGs from the standpoint of diversification of risk, namely simple mixed strategies with loners, and prove the existence of a dynamical regime in which the restrictions ono longer hold. Considering two kinds of mixed strategies associated with participants (cooperators or defectors) and non-participants (loners), we can recover all basic evolutionary dynamics of the two strategies: dominance; coexistence; bistability; and neutrality, as special cases depending on pairs of probabilities. Of special interest is that the expected pay-off of each mixed strategy exceeds the pay-off of loners at some interior equilibrium in the coexistence region.

    2016-12-01

    In the public goods games, players attempt to optimize their payoffs, following as fair, generous, and extortionate rules according to the pattern needed for obtaining their expected profits compared to those of their opponents. In first type of rule (the fair one), players seek equal profits of the opponent, and the generous rule induces to lower payoff than that of opposite players, while the extortionate rule leads to higher payoffs than that of their opponents. To model the three types of behaviors, we introduce a conditional strategy with a parameter χ, which control conditions of existence of the three behaviors. Therefore, players may contribute in a group, but may not contribute in the other group, because it depends on conditions of their opponents. Simulation results show that there exists a pure cooperation state when parameter χ is moderate, even for a lower multiplication factor. Because conditional players cautiously contribute they can form compact clusters to prevent the invasion of defection and finally spread the cooperation when defectors die out.

    PubMed

    Dollar, D

    2001-01-01

    Four points are made about globalization and health. First, economic integration is a powerful force for raising the incomes of poor countries. In the past 20 years several large developing countries have opened up to trade and investment, and they are growing well--faster than the rich countries. Second, there is no tendency for income inequality to increase in countries that open up. The higher growth that accompanies globalization in developing countries generally benefits poor people. Since there is a large literature linking income of the poor to health status, we can be reasonably confident that globalization has indirect positive effects on nutrition, infant mortality and other health issues related to income. Third, economic integration can obviously have adverse health effects as well: the transmission of AIDS through migration and travel is a dramatic recent example. However, both relatively closed and relatively open developing countries have severe AIDS problems. The practical solution lies in health policies, not in policies on economic integration. Likewise, free trade in tobacco will lead to increased smoking unless health-motivated disincentives are put in place. Global integration requires supporting institutions and policies. Fourth, the international architecture can be improved so that it is more beneficial to poor countries. For example, with regard to intellectual property rights, it may be practical for pharmaceutical innovators to choose to have intellectual property rights in either rich country markets or poor country ones, but not both. In this way incentives could be strong for research on diseases in both rich and poor countries.

In the past 20 years several large developing countries have opened up to trade and investment, and they are growing well--faster than the rich countries. Second, there is no tendency for income inequality to increase in countries that open up. The higher growth that accompanies globalization in developing countries generally benefits poor people.

We first show mathematically and numerically that prior agreements with posterior compensations provide a strategic solution that leads to substantial levels of cooperation in the context of public goods games, results that are corroborated by available experimental data. Notwithstanding this success, one cannot, as with other approaches, fully exclude the presence of defectors, raising the question of how they can be dealt with to avoid the demise of the common good. We show that both avoiding creation of the common good, whenever full agreement is not reached, and limiting the benefit that disagreeing defectors can acquire, using costly restriction mechanisms, are relevant choices. Nonetheless, restriction mechanisms are found the more favourable, especially in larger group interactions. Given decreasing restriction costs, introducing restraining measures to cope with public goods free-riding issues is the ultimate advantageous solution for all participants, rather than avoiding its creation.

  7. Public goods games with reward in finite populations.

    2011-07-01

    Public goods games paraphrase the problem of cooperation in game theoretical terms. Cooperators contribute to a public good and thereby increase the welfare of others at a cost to themselves. Defectors consume the public good but do not pay its cost and therefore outperform cooperators. Hence, according to genetic or cultural evolution, defectors should be favored and the public good disappear - despite the fact that groups of cooperators are better off than groups of defectors. The maximization of short term individual profits causes the demise of the common resource to the detriment of all. This outcome can be averted by introducing incentives to cooperate. Negative incentives based on the punishment of defectors efficiently stabilize cooperation once established but cannot initiate cooperation. Here we consider the complementary case of positive incentives created by allowing individuals to reward those that contribute to the public good. The finite-population stochastic dynamics of the public goods game with reward demonstrate that reward initiates cooperation by providing an escape hatch out of states of mutual defection. However, in contrast to punishment, reward is unable to stabilize cooperation but, instead, gives rise to a persistent minority of cooperators.

This intervention is tested in a large-scale field experiment (n = 770,946) in which people are encouraged to vote through get-out-the-vote letters. We vary whether the letters include the message, “We may call you after the election to ask about your voting experience.” Increasing the perceived observability of whether people vote by including that message increased the impact of the get-out-the-vote letters by more than the entire effect of a typical get-out-the-vote letter. This technique for increasing perceived observability can be replicated whenever public goods solicitations are made in private. PMID:27114553

    2014-01-01

    Summary: Bacteria frequently live in densely populated surface-bound communities, termed biofilms [1-4]. Biofilm-dwelling cells rely on secretion of extracellular substances to construct their communities and to capture nutrients from the environment [5]. Some secreted factors behave as cooperative public goods: they can be exploited by non-producing cells [6-11]. The means by which public-good-producing bacteria avert exploitation in biofilm environments are largely unknown. Using experiments with Vibrio cholerae, which secretes extracellular enzymes to digest its primary food source, the solid polymer chitin, we show that the public goods dilemma may be solved by two very different mechanisms: cells can produce thick biofilms that confine the goods to producers, or fluid flow can remove soluble products of chitin digestion, denying access to non-producers. Both processes are unified by limiting the distance over which enzyme-secreting cells provide benefits to neighbors, resulting in preferential benefit to nearby clonemates and allowing kin selection to favor public good production. Our results demonstrate new mechanisms by which the physical conditions of natural habitats can interact with bacterial physiology to promote the evolution of cooperation. PMID:24332540

    Smallholder agricultural systems, strongly dependent on water resources and investments in shared infrastructure, make a significant contribution to food security in developing countries. These communities are being increasingly integrated into the global economy and are exposed to new global climate-related risks that may affect their willingness to cooperate in community-level collective action problems. We performed field experiments on public goods with private and collective risks in 118 small-scale rice-producing communities in four countries. Our results indicate that increasing the integration of those communities with the broader economic system is associated with lower investments in public goods when facing collective risks. These findings indicate that local public good provision may be negatively affected by collective risks, especially in communities more integrated with the market economy.

  18. Globalization of public health law and ethics.

    Sohn, Myongsei

    The Constitution of the World Health Organization (1946) states that the "enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being without distinction of race, religion, political belief, economic or social position." The international legal framework for this right was laid by the Universal Declaration of Human Rights (1948) and reaffirmed in the International Covenant on Economic, Social, and Cultural Rights (1966) and the Declaration of Alma-Ata (1978). In recent years, the framework has been developed on 10 key elements: national and international human rights, laws, norms, and standards; resource constraints and progressive realization; obligations of immediate effect; freedoms and entitlements; available, accessible, acceptable, and good quality; respect, protect, and fulfill; non-discrimination, equality, and vulnerability; active and informed participation; international assistance and cooperation; and monitoring and accountability. Whereas public health law plays an essential role in the protection and promotion of the right to health, the emergence of SARS (2003) highlighted the urgent need to reform national public health laws and international obligations relating to public health in order to meet the new realities of a globalized world, leading to the WHO Framework Convention on Tobacco Control (2003) and the revision of the WHO International Health Regulations (2005). The Asian Institute for Bioethics and Health Law, in conjunction with the Republic of Korea's Ministry of Health and Welfare and the WHO International Digest of Health Legislation, conducted a comparative legal analysis of national public health laws in various countries through a project entitled Domestic Profiles of Public/Population Health Legislation (2006), which underscored the importance of recognizing the political and social contexts of distinct legal cultures, including Western, Asian, Islamic, and African.

  19. A public goods approach to major evolutionary innovations.

    PubMed

    Erwin, D H

    2015-07-01

    The history of life is marked by a small number of major transitions, whether viewed from a genetic, ecological, or geological perspective. Specialists from various disciplines have focused on the packaging of information to generate new evolutionary individuals, on the expansion of ecological opportunity, or the abiotic drivers of environmental change to which organisms respond as the major drivers of these episodes. But the critical issue for understanding these major evolutionary transitions (METs) lies in the interactions between environmental, ecologic, and genetic change. Here, I propose that public goods may serve as one currency of such interactions: biological products that are non-excludable and non-rivalrous. Such biological public goods may be involved in either the generation of new evolutionary variation, as with genetic sequences that are easily transferred between different microbial lineages, or in the construction of new ecological niches, as with the progressive oxygenation of the oceans and atmosphere. Attention to public goods emphasizes the processes by which organisms actively construct their own evolutionary opportunities. Such public goods may have facilitated some METs.

  20. The role of noise in the spatial public goods game

    NASA Astrophysics Data System (ADS)

    Javarone, Marco Alberto; Battiston, Federico

    2016-07-01

    In this work we aim to analyze the role of noise in the spatial public goods game, one of the most famous games in evolutionary game theory. The dynamics of this game is affected by a number of parameters and processes, namely the topology of interactions among the agents, the synergy factor, and the strategy revision phase. The latter is a process that allows agents to change their strategy. Notably, rational agents tend to imitate richer neighbors, in order to increase the probability to maximize their payoff. By implementing a stochastic revision process, it is possible to control the level of noise in the system, so that even irrational updates may occur. In particular, in this work we study the effect of noise on the macroscopic behavior of a finite structured population playing the public goods game. We consider both the case of a homogeneous population, where the noise in the system is controlled by tuning a parameter representing the level of stochasticity in the strategy revision phase, and a heterogeneous population composed of a variable proportion of rational and irrational agents. In both cases numerical investigations show that the public goods game has a very rich behavior which strongly depends on the amount of noise in the system and on the value of the synergy factor. To conclude, our study sheds a new light on the relations between the microscopic dynamics of the public goods game and its macroscopic behavior, strengthening the link between the field of evolutionary game theory and statistical physics.

Biofilm-dwelling cells rely on secretion of extracellular substances to construct their communities and to capture nutrients from the environment. Some secreted factors behave as cooperative public goods: they can be exploited by non-producing cells.

Both processes limit the distance over which enzyme-secreting cells provide a benefit to neighbors, resulting in preferential benefit to nearby clonemates. Our results demonstrate how bacterial physiology and environmental conditions can interact with social phenotypes to influence the evolutionary dynamics of cooperation within biofilms.

    Background Experience with public engagement activities regarding the risks and benefits of science and technology (S&T) is growing, especially in the industrialized world. However, public engagement in the developing world regarding S&T risks and benefits to explore health issues has not been widely explored. Methods This paper gives an overview about public engagement and related concepts, with a particular focus on challenges and benefits in the developing world. We then describe an Internet-based platform, which seeks to both inform and engage youth and the broader public on global water issues and their health impacts. Finally, we outline a possible course for future action to scale up this and similar online public engagement platforms. Results The benefits of public engagement include creating an informed citizenry, generating new ideas from the public, increasing the chances of research being adopted, increasing public trust, and answering ethical research questions. Public engagement also fosters global communication, enables shared experiences and methodology, standardizes strategy, and generates global viewpoints. This is especially pertinent to the developing world, as it encourages previously marginalized populations to participate on a global stage. One of the core issues at stake in public engagement is global governance of science and technology. Also, beyond benefiting society at large, public engagement in science offers benefits to the scientific enterprise itself. Conclusion Successful public engagement with developing world stakeholders will be a critical part of implementing new services and technologies. Interactive engagement platforms, such as the Internet, have the potential to unite people globally around relevant health issues. PMID:18492256

    2016-09-01

    We study the coevolution of culture and cooperation by combining the Axelrod model of cultural dissemination with a spatial public goods game, incorporating both noise and social influence. Both participation and cooperation in public goods games are conditional on cultural similarity. We find that a larger "scope of cultural possibilities" in the model leads to the survival of cooperation, when noise is not present, and a higher probability of a multicultural state evolving, for low noise rates. High noise rates, however, lead to both rapid extinction of cooperation and collapse into cultural "anomie," in which stable cultural regions fail to form. These results suggest that cultural diversity can actually be beneficial for the evolution of cooperation, but that cultural information needs to be transmitted accurately in order to maintain both coherent cultural groups and cooperation.

    We present a simple yet effective mechanism promoting cooperation under full anonymity by allowing for voluntary participation in public goods games. This natural extension leads to ``rock-scissors-paper''-type cyclic dominance of the three strategies, cooperate, defect, and loner. In spatial settings with players arranged on a regular lattice, this results in interesting dynamical properties and intriguing spatiotemporal patterns. In particular, variations of the value of the public good leads to transitions between one-, two-, and three-strategy states which either are in the class of directed percolation or show interesting analogies to Ising-type models. Although volunteering is incapable of stabilizing cooperation, it efficiently prevents successful spreading of selfish behavior.

    In this paper we test the effect of non-binding defaults on the level of contribution to a public good. We manipulate the default numbers appearing on the decision screen to nudge subjects toward a free-rider strategy or a perfect conditional cooperator strategy. Our results show that the vast majority of our subjects did not adopt the default numbers, but their stated strategy was affected by the default. Moreover, we find that our manipulation spilled over to a subsequent repeated public goods game where default was not manipulated. Here we found that subjects who previously saw the free rider default were significantly less cooperative than those who saw the perfect conditional cooperator default. PMID:26717569

    One of the most continually vexing problems in society is the variability with which citizens support endeavors that are designed to help a great number of people. In this article, we examine the twin roles of cooperative and antagonistic behavior in this variability. We find that each plays an important role, though their contributions are, understandably, at odds. It is this opposition that produces seeming unpredictability in citizen response to collective need. In fact, we suggest that careful consideration of the research allows one to often predict when efforts to provide a collectively beneficial good will succeed and when they will fail. To understand the dynamics of participation in response to collective need, it is necessary to distinguish between the primary types of need situations. A public good is an entity that relies in whole or in part on contributions to be provided. Examples of public goods are charities and public broadcasting. Public goods require that citizens experience a short-term loss (of their contribution) in order to realize a long-term gain (of the good). However, because everyone can use the good once it is provided, there is also an incentive to not contribute, let others give, and then take advantage of their efforts. This state of affairs introduces a conflict between doing what is best for oneself and what is best for the group. In a public goods situation, cooperation and antagonism impact how one resolves this conflict. The other major type of need situation is a common-pool resource problem. Here, a good is fully provided at the outset, and citizens may sample from it. The resource is usually, but not necessarily, partially replenished. Examples of replenished resources are drinking water and trees; examples of resources that are functionally not replenished are oil and minerals. Common-pool resources allow citizens to experience a short-term gain (by getting what they want in the early life of the resource) but also present

    Recent decades have been marked by the explosive development of innovative scientific, technological and business products and processes. Despite their immense impact on health globally, little has been accomplished in the field of global public health to incorporate, address and harness such innovations in practice. In order to meet the world's growing health needs, it is essential that global public health accepts and adapts to these innovations. Moreover, such innovations must be implemented equitably in ways that will best serve their intended recipients, without deepening health- and access-related disparities. This article will briefly discuss the wide array of technologies in the pipeline that will affect global public health practice, their impact on the field and on populations and the issues facing the field in adopting these innovations.

    The challenges posed by a globalised world have made it imperative for society to search for solutions to emerging issues and to develop new ways of looking at old problems. Current discussions about global public health demand a shift in paradigms and the strategic positioning of public health within broader policy discussions that will enable it to influence political and action agendas. Critical to responding to these challenges is the generation, transmission and dissemination of new knowledge to create value. Recognising the cutting-edge role of knowledge, as a new form of capital that drives innovation and transforms society, the formation of knowledge networks is viewed as a strategy for developing a shared intellectual, conceptual and ethical infrastructure for the field of global public health. These knowledge networks are envisioned as a vehicle for sharing diverse perspectives, encouraging debate and sustaining alternative ways of thinking about and responding to the challenges that confront global public health today and in the future.

  11. Optional contributions have positive effects for volunteering public goods games

    Public goods (PG) games with the volunteering mechanism are referred to as volunteering public goods (VPG) games, in which loners are introduced to the PG games, and a loner obtains a constant payoff but not participating the game. Considering that small contributions may have positive effects to encourage more players with bounded rationality to contribute, this paper introduces optional contributions (high value or low value) to these typical VPG games-a cooperator can contribute a high or low payoff to the public pools. With the low contribution, the logit dynamics show that cooperation can be promoted in a well mixed population comparing to the typical VPG games, furthermore, as the multiplication factor is greater than a threshold, the average payoff of the population is also enhanced. In spatial VPG games, we introduce a new adjusting mechanism that is an approximation to best response. Some results in agreement with the prediction of the logit dynamics are found. These simulation results reveal that for VPG games the option of low contributions may be a better method to stimulate the growth of cooperation frequency and the average payoff of the population.

  12. Directional learning and the provisioning of public goods

    We consider an environment where players are involved in a public goods game and must decide repeatedly whether to make an individual contribution or not. However, players lack strategically relevant information about the game and about the other players in the population. The resulting behavior of players is completely uncoupled from such information, and the individual strategy adjustment dynamics are driven only by reinforcement feedbacks from each player's own past. We show that the resulting ``directional learning'' is sufficient to explain cooperative deviations away from the Nash equilibrium. We introduce the concept of k-strong equilibria, which nest both the Nash equilibrium and the Aumann-strong equilibrium as two special cases, and we show that, together with the parameters of the learning model, the maximal k-strength of equilibrium determines the stationary distribution. The provisioning of public goods can be secured even under adverse conditions, as long as players are sufficiently responsive to the changes in their own payoffs and adjust their actions accordingly. Substantial levels of public cooperation can thus be explained without arguments involving selflessness or social preferences, solely on the basis of uncoordinated directional (mis)learning.

    Encouraged by the interaction between two species of microbes, in which one species is capable of replenishing the public resources and the other is not, the dilemma structure (the long-term sustainability of the population) hidden in a system where public goods are defined as diffusible was examined. In a series of simulations in which the three major parameters governing the dynamics of the system were varied, following the effect of the spatial structure that results from resource diffusion and distribution, the dynamics show a rich diversity, including cooperator-dominated, extinct, and coexistent results. If the dilemma is strong, the chance of surviving cooperators is small and the population tends to extinction even though coexistence is possible. By contrast, if a weak dilemma is given, the affluent resources make cooperators dominant over defectors.

    In this paper, we study the public goods games with punishment by adopting the well-known approximate best response dynamics. It shows that the evolution of cooperation is affected by two aspects when other parameters are fixed. One is the punishment mechanism which can avoid the dilemma of lacking investment, and the other is the degree of rationality. Theoretical analysis and numerical results indicate that the existence of punishment mechanism and distribution of rationality are the keys to the enhancement of cooperation level. We also testify that they can heavily influence the payoffs of system as well. The findings in this paper may provide a deeper understanding of some social dilemmas.

    2016-08-01

    This article offers an integrated account of two strands of global health justice: health-related human rights and health-related common goods. After sketching a general understanding of the nature of human rights, it proceeds to explain both how individual human rights are to be individuated and the content of their associated obligations specified. With respect to both issues, the human right to health is taken as the primary illustration. It is argued that (1) the individuation of the right to health is fixed by reference to the subject matter of its corresponding obligations, and not by the interests it serves, and (2) the specification of the content of that right must be properly responsive to thresholds of possibility and burden. The article concludes by insisting that human rights cannot constitute the whole of global health justice and that, in addition, other considerations-including the promotion of health-related global public goods-should also shape such policy. Moreover, the relationship between human rights and common goods should not be conceived as mutually exclusive. On the contrary, there sometimes exists an individual right to some aspect of a common good, including a right to benefit from health-related common goods such as programmes for securing herd immunity from diphtheria.

    Classic socio-ecological theory holds that the occurrence of aggressive range defence is primarily driven by ecological incentives, most notably by the economic defendability of an area or the resources it contains. While this ecological cost–benefit framework has great explanatory power in solitary or pair-living species, comparative work on group-living primates has always found economic defendability to be a necessary, but not sufficient condition to account for the distribution of effective range defence across the taxon. This mismatch between theory and observation has recently been ascribed to a collective action problem among group members in, what is more informatively viewed as, a public goods dilemma: mounting effective defence of a communal range against intrusions by outgroup conspecifics. We here further develop this framework, and report on analyses at three levels of biological organization: across species, across populations within a single lineage and across groups and individuals within a single population. We find that communal range defence in primates very rarely involves collective action sensu stricto and that it is best interpreted as the outcome of opportunistic and strategic individual-level decisions. Whether the public good of a defended communal range is produced by solitary, joint or collective action is thus the outcome of the interplay between the unique characteristics of each individual, local and current socio-ecological conditions, and fundamental life-history traits of the species.

    2016-08-01

    Tolerance implies enduring trying circumstances with a fair and objective attitude. To determine whether evolutionary advantages might be stemming from diverse levels of tolerance in a population, we study a spatial public goods game, where in addition to cooperators, defectors, and loners, tolerant players are also present. Depending on the number of defectors within a group, a tolerant player can either cooperate in or abstain from a particular instance of the game. We show that the diversity of tolerance can give rise to synergistic effects, wherein players with a different threshold in terms of the tolerated number of defectors in a group compete most effectively against defection and default abstinence. Such synergistic associations can stabilise states of full cooperation where otherwise defection would dominate. We observe complex pattern formation that gives rise to an intricate phase diagram, where invisible yet stable strategy alliances require outmost care lest they are overlooked. Our results highlight the delicate importance of diversity and tolerance for the provisioning of public goods, and they reveal fascinating subtleties of the spatiotemporal dynamics that is due to the competition of subsystem solutions in structured populations.

  20. Public-private interactions in global food safety governance.

    2014-01-01

    In response to an apparent decline in global food safety, numerous public and private regulatory initiatives have emerged to restore public confidence. This trend has been particularly marked by the growing influence of private regulators such as multinational food companies, supermarket chains and non-governmental organizations (NGOs), who employ private standards, certification protocols, third-party auditing, and transnational contracting practices. This paper explores how the structure and processes of private food safety governance interact with traditional public governance regimes, focusing on Global Good Agricultural Practices (GlobalGAP) as a primary example of the former. Due to the inefficiency and ineffectiveness of public regulation in the face of global problems, private governance in food safety has gradually replaced states' command-and-control regulation with more flexible, market-oriented mechanisms. The paper concludes by emphasizing the importance of constructive regime interaction instead of institutional boundary building to global food safety governance. Public and private ordering must each play a role as integral parts of a larger, dynamic and evolving governance complex.

International environmental law offers a viable strategy for enhancing public health through the promotion of increased awareness of the linkages between health and environment, mobilization of technical and financial resources, strengthening of research and monitoring, enforcement of health-related standards, and promotion of global cooperation. An enhanced capacity to utilize international environmental law could lead to significant worldwide gains in public health. PMID:12571726

    Environmental public goods--including national parks, clean air/water, and ecosystem services--provide substantial benefits on a global scale. These goods have unique characteristics in that they are typically "nonmarket" goods, with values from both use and passive use that accrue to a large number of individuals both in current and future generations. In this study, we test the hypothesis that neural signals in areas correlated with subjective valuations for essentially all other previously studied categories of goods (ventromedial prefrontal cortex and ventral striatum) also correlate with environmental valuations. We use contingent valuation (CV) as our behavioral tool for measuring valuations of environmental public goods. CV is a standard stated preference approach that presents survey respondents with information on an issue and asks questions that help policymakers determine how much citizens are willing to pay for a public good or policy. We scanned human subjects while they viewed environmental proposals, along with three other classes of goods. The presentation of all four classes of goods yielded robust and similar patterns of temporally synchronized brain activation within attentional networks. The activations associated with the traditional classes of goods replicate previous correlations between neural activity in valuation areas and behavioral preferences. In contrast, CV-elicited values for environmental proposals did not correlate with brain activity at either the individual or population level. For a sub-population of participants, CV-elicited values were correlated with activity within the dorsomedial prefrontal cortex, a region associated with cognitive control and shifting decision strategies. The results show that neural activity associated with the subjective valuation of environmental proposals differs profoundly from the neural activity associated with previously examined goods and preference measures.

  3. Infectious disease surveillance in the United States and the United Kingdom: from public goods to the challenges of new technologies.

    Infectious diseases are a long-standing and continuing threat to health and welfare, with their containment dependent on national disease surveillance and response capacities. This article discusses infectious disease surveillance in the United States and the United Kingdom, examining historical national traditions for identifying and controlling infectious disease risks and how globalization and technical advances have influenced the evolution of their respective approaches. The two systems developed in different but parallel ways. In the United States, surveillance remained quite localized at the state level until the early twentieth century and still retains many of those features. The U.K. approach became centralized from the latter part of the nineteenth century and has principally remained so. In both cases, disease surveillance was traditionally conceived as a public good, where national or local authorities held sovereign rights and power to protect public health. With the increasing globalized nature of infectious disease, such notions shifted toward surveillance as a global public good, with countries responding in turn by creating new global health governance arrangements and regulations. However, the limitations of current surveillance systems and the strong hold of national interests place into question the provision of surveillance as a global public good. These issues are further highlighted with the introduction of new surveillance technologies, which offer opportunities for improved disease detection and identification but also create potential tensions between individual rights, corporate profit, equitable access to technology, and national and global public goods.

    Public goods and common-pool resources are fundamental features of biological and social systems, and pose core challenges in achieving sustainability; for such situations, the immediate interests of individuals and the societies in which they are embedded are in potential conflict, involving game-theoretic considerations whose resolution need not serve the collective good. Evolution has often confronted such dilemmas--e.g., in bacterial biofilms--in the challenges of cancer, in nitrogen fixation and chelation, in the production of antibiotics, and in collective action problems across animal groups; there is much to learn from the Darwinian resolution of these situations for how to address problems our societies face today. Addressing these problems involves understanding the emergence of cooperative agreements, from reciprocal altruism and insurance arrangements to the social norms and more formal institutions that maintain societies. At the core are the issues of how individuals and societies discount the future and the interests of others, and the degree that individual decisions are influenced by regard for others. Ultimately, as Garrett Hardin suggested, the solution to problems of the commons is in "mutual coercion, mutually agreed upon," and hence in how groups of individuals form and how they arrive at decisions that ultimately benefit all.

    The public goods game is one of the most famous models for studying the evolution of cooperation in sizable groups. The multiplication factor in this game can characterize the investment return from the public good, which may be variable depending on the interactive environment in realistic situations. Instead of using the same universal value, here we consider that the multiplication factor in each group is updated based on the differences between the local and global interactive environments in the spatial public goods game, but meanwhile limited to within a certain range. We find that the adaptive and bounded investment returns can significantly promote cooperation. In particular, full cooperation can be achieved for high feedback strength when appropriate limitation is set for the investment return. Also, we show that the fraction of cooperators in the whole population can become larger if the lower and upper limits of the multiplication factor are increased. Furthermore, in comparison to the traditionally spatial public goods game where the multiplication factor in each group is identical and fixed, we find that cooperation can be better promoted if the multiplication factor is constrained to adjust between one and the group size in our model. Our results highlight the importance of the locally adaptive and bounded investment returns for the emergence and dominance of cooperative behavior in structured populations.

    Humans often cooperate in public goods games and situations ranging from family issues to global warming. However, evolutionary game theory predicts that the temptation to forgo the public good mostly wins over collective cooperative action, and this is often also seen in economic experiments. Here we show how social diversity provides an escape from this apparent paradox. Up to now, individuals have been treated as equivalent in all respects, in sharp contrast with real-life situations, where diversity is ubiquitous. We introduce social diversity by means of heterogeneous graphs and show that cooperation is promoted by the diversity associated with the number and size of the public goods game in which each individual participates and with the individual contribution to each such game. When social ties follow a scale-free distribution, cooperation is enhanced whenever all individuals are expected to contribute a fixed amount irrespective of the plethora of public goods games in which they engage. Our results may help to explain the emergence of cooperation in the absence of mechanisms based on individual reputation and punishment. Combining social diversity with reputation and punishment will provide instrumental clues on the self-organization of social communities and their economical implications.

    2010-11-01

    The promise of punishment and reward in promoting public cooperation is debatable. While punishment is traditionally considered more successful than reward, the fact that the cost of punishment frequently fails to offset gains from enhanced cooperation has lead some to reconsider reward as the main catalyst behind collaborative efforts. Here we elaborate on the "stick vs. carrot" dilemma by studying the evolution of cooperation in the spatial public goods game, where besides the traditional cooperators and defectors, rewarding cooperators supplement the array of possible strategies. The latter are willing to reward cooperative actions at a personal cost, thus effectively downgrading pure cooperators to second-order free-riders due to their unwillingness to bear these additional costs. Consequently, we find that defection remains viable, especially if the rewarding is costly. Rewards, however, can promote cooperation, especially if the synergetic effects of cooperation are low. Surprisingly, moderate rewards may promote cooperation better than high rewards, which is due to the spontaneous emergence of cyclic dominance between the three strategies.

    2015-08-21

    Recently, Press and Dyson have proposed a new class of probabilistic and conditional strategies for the two-player iterated Prisoner's Dilemma, so-called zero-determinant strategies. A player adopting zero-determinant strategies is able to pin the expected payoff of the opponents or to enforce a linear relationship between his own payoff and the opponents' payoff, in a unilateral way. This paper considers zero-determinant strategies in the iterated public goods game, a representative multi-player game where in each round each player will choose whether or not to put his tokens into a public pot, and the tokens in this pot are multiplied by a factor larger than one and then evenly divided among all players. The analytical and numerical results exhibit a similar yet different scenario to the case of two-player games: (i) with small number of players or a small multiplication factor, a player is able to unilaterally pin the expected total payoff of all other players; (ii) a player is able to set the ratio between his payoff and the total payoff of all other players, but this ratio is limited by an upper bound if the multiplication factor exceeds a threshold that depends on the number of players.

    It is becoming increasingly difficult to reconcile the observed extent of horizontal gene transfers with the central metaphor of a great tree uniting all evolving entities on the planet. In this manuscript we describe the Public Goods Hypothesis and show that it is appropriate in order to describe biological evolution on the planet. According to this hypothesis, nucleotide sequences (genes, promoters, exons, etc.) are simply seen as goods, passed from organism to organism through both vertical and horizontal transfer. Public goods sequences are defined by having the properties of being largely non-excludable (no organism can be effectively prevented from accessing these sequences) and non-rival (while such a sequence is being used by one organism it is also available for use by another organism). The universal nature of genetic systems ensures that such non-excludable sequences exist and non-excludability explains why we see a myriad of genes in different combinations in sequenced genomes. There are three features of the public goods hypothesis. Firstly, segments of DNA are seen as public goods, available for all organisms to integrate into their genomes. Secondly, we expect the evolution of mechanisms for DNA sharing and of defense mechanisms against DNA intrusion in genomes. Thirdly, we expect that we do not see a global tree-like pattern. Instead, we expect local tree-like patterns to emerge from the combination of a commonage of genes and vertical inheritance of genomes by cell division. Indeed, while genes are theoretically public goods, in reality, some genes are excludable, particularly, though not only, when they have variant genetic codes or behave as coalition or club goods, available for all organisms of a coalition to integrate into their genomes, and non-rival within the club. We view the Tree of Life hypothesis as a regionalized instance of the Public Goods hypothesis, just like classical mechanics and euclidean geometry are seen as regionalized

    Visual-tactile carry-over effects of global/local processing (attention to the whole, versus the details) have been reported under active touch conditions. We investigated whether carry-over effects of global/local processing also occur for passive touch and whether global/local processing has differential effects on affective and discriminative aspects of touch. Participants completed two tactile tasks involving pleasantness rating and discrimination of a set of tactile vibrations before and after completing a version of the Navon task that encouraged a focus on the global (n = 30), local (n = 30), or both (n = 30) features of a series of visual stimuli. In line with previous research suggesting a link between global processing and positive emotion, global processing increased pleasantness ratings of high-frequency (but not low-frequency) tactile vibrations. Local processing did not improve the ability to discriminate between vibrations of different frequencies, however. There was some evidence of a tactile-visual carry-over effect; prior local processing of tactile vibrations reduced global precedence during the Navon task in the control group. We have shown carry-over effects of global versus local processing on passive touch perception. These findings provide further evidence suggesting that a common perceptual mechanism determines processing level across modalities and show for the first time that prior global processing affects the pleasantness of touch.

    Cooperation is fundamental to human societies, and one of the important paths for its emergence and maintenance is reciprocity. In prisoner’s dilemma (PD) experiments, reciprocal strategies are often effective at attaining and maintaining high cooperation. In many public goods (PG) games or n-person PD experiments, however, reciprocal strategies are not successful at engendering cooperation. In the present paper, we attribute this difficulty to a coordination problem against free riding among reciprocators: Because it is difficult for the reciprocators to coordinate their behaviors against free riders, this may lead to inequality among players, which will demotivate them from cooperating in future rounds. We propose a new mechanism, institutionalized reciprocity (IR), which refers to embedding the reciprocal strategy as an institution (i.e., institutionalizing the reciprocal strategy). We experimentally demonstrate that IR can prevent groups of reciprocators from falling into coordination failure and achieve high cooperation in PG games. In conclusion, we argue that a natural extension of the present study will be to investigate the possibility of IR to serve as a collective punishment system. PMID:27248493

    Altruistic punishment for defectors is considered as a key motive for the explanation of cooperation. However, there is no clear border between the cooperative and defective behaviors in a continuous strategy game. We propose a model to study the effect of punishment on the evolution of cooperation in continuous public goods game, wherein individuals have the traits to punish the co-players based on social tolerance. We show that a reasonable punishment with a uniform tolerance can spur individuals to make more investments. Additionally, for a fixed punishment cost and a fixed fine, a moderate value of tolerance can result in the best promotion of cooperation. Furthermore, we investigate the coevolutionary dynamics of investment and tolerance. We find that the population splits into two branches: high-tolerance individuals who make high investments and low-tolerance individuals who make low investments. A dynamic equilibrium is achieved between these two types of individuals. Our work extends punishment to continuous cooperative behaviors and the results may enhance the understanding of altruistic punishment in the evolution of human cooperation.

  17. Heuristics guide cooperative behaviors in public goods game

    In public goods game (PGG), player's cooperative behavior is not pure economical rationality, but social preference and prosocial intuition play extremely important roles as well. Social preference and prosocial intuition can be guided by heuristics from one's neighbors in daily life. To better investigate the impacts of heuristics on the evolution of cooperation, four types of agents are introduced into our spatial PGG. Through numerical simulations, results show that the larger percentages of cooperators with independent thought, the easier emergence and maintenance of collective cooperative behaviors. Additionally, we find that differentia heuristic capability has great effect on the equilibrium of PGG. Cooperation can be obviously promoted, when heuristic capability of cooperators with independent thought is stronger than that of defectors with independent thought. Finally, we observe that cooperators with independent thought and defectors with independent thought are favorable for the formation of some high quality clusters, which can resist the invasion between each other. Our work may help us understand more clearly the mechanism of cooperation in real world.

    Economic experiments are often used to study if humans altruistically value the welfare of others. A canonical result from public-good games is that humans vary in how they value the welfare of others, dividing into fair-minded conditional cooperators, who match the cooperation of others, and selfish noncooperators. However, an alternative explanation for the data are that individuals vary in their understanding of how to maximize income, with misunderstanding leading to the appearance of cooperation. We show that (i) individuals divide into the same behavioral types when playing with computers, whom they cannot be concerned with the welfare of; (ii) behavior across games with computers and humans is correlated and can be explained by variation in understanding of how to maximize income; (iii) misunderstanding correlates with higher levels of cooperation; and (iv) standard control questions do not guarantee understanding. These results cast doubt on certain experimental methods and demonstrate that a common assumption in behavioral economics experiments, that choices reveal motivations, will not necessarily hold.

    Prosociality is one of the most distinctive features of human beings but there are individual differences in cooperative behavior. Employing the twin method, we examined the heritability of cooperativeness and its outcomes on public goods games using a strategy method. In two experiments (Study 1 and Study 2), twin participants were asked to indicate (1) how much they would contribute to a group when they did not know how much the other group members were contributing, and (2) how much they would contribute if they knew the contributions of others. Overall, the heritability estimates were relatively small for each type of decision, but heritability was greater when participants knew that the others had made larger contributions. Using registered decisions in Study 2, we conducted seven Monte Carlo simulations to examine genetic and environmental influences on the expected game payoffs. For the simulated one-shot game, the heritability estimates were small, comparable to those of game decisions. For the simulated iterated games, we found that the genetic influences first decreased, then increased as the numbers of iterations grew. The implication for the evolution of individual differences in prosociality is discussed. PMID:25954213

    Network reconstruction is a fundamental problem for understanding many complex systems with unknown interaction structures. In many complex systems, there are indirect interactions between two individuals without immediate connection but with common neighbors. Despite recent advances in network reconstruction, we continue to lack an approach for reconstructing complex networks with indirect interactions. Here we introduce a two-step strategy to resolve the reconstruction problem, where in the first step, we recover both direct and indirect interactions by employing the Lasso to solve a sparse signal reconstruction problem, and in the second step, we use matrix transformation and optimization to distinguish between direct and indirect interactions. The network structure corresponding to direct interactions can be fully uncovered. We exploit the public goods game occurring on complex networks as a paradigm for characterizing indirect interactions and test our reconstruction approach. We find that high reconstruction accuracy can be achieved for both homogeneous and heterogeneous networks, and a number of empirical networks in spite of insufficient data measurement contaminated by noise. Although a general framework for reconstructing complex networks with arbitrary types of indirect interactions is yet lacking, our approach opens new routes to separate direct and indirect interactions in a representative complex system.

  4. Stigmatized ethnicity, public health, and globalization.

    2008-01-01

    The prejudicial linking of infection with ethnic minority status has a long-established history, but in some ways this association may have intensified under the contemporary circumstances of the "new public health" and globalization. This study analyzes this conflation of ethnicity and disease victimization by considering the stigmatization process that occurred during the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS) in Toronto. The attribution of stigma during the SARS outbreak occurred in multiple and overlapping ways informed by: (i) the depiction of images of individuals donning respiratory masks; (ii) employment status in the health sector; and (iii) Asian-Canadian and Chinese-Canadian ethnicity. In turn, stigmatization during the SARS crisis facilitated a moral panic of sorts in which racism at a cultural level was expressed and rationalized on the basis of a rhetoric of the new public health and anti-globalization sentiments. With the former, an emphasis on individualized self-protection, in the health sense, justified the generalized avoidance of those stigmatized. In relation to the latter, in the post-9/11 era, avoidance of the stigmatized other was legitimized on the basis of perceiving the SARS threat as a consequence of the mixing of different people predicated by economic and cultural globalization.

    We found that a network-organized metapopulation of cooperators, defectors, and destructive agents playing the public goods game with mutations can collectively reach global synchronization or chimera states. Global synchronization is accompanied by a collective periodic burst of cooperation, whereas chimera states reflect the tendency of the networked metapopulation to be fragmented in clusters of synchronous and incoherent bursts of cooperation. Numerical simulations have shown that the system's dynamics switches between these two steady states through a first order transition. Depending on the parameters determining the dynamical and topological properties, chimera states with different numbers of coherent and incoherent clusters are observed. Our results present the first systematic study of chimera states and their characterization in the context of evolutionary game theory. This provides a valuable insight into the details of their occurrence, extending the relevance of such states to natural and social systems.

    International efforts to provide global public goods often face the challenges of coordinating national contributions and distributing costs equitably in the face of uncertainty, inequality, and free-riding incentives. In an experimental setting, we distribute endowments unequally among a group of people who can reach a fixed target sum through successive money contributions, knowing that if they fail, they will lose all their remaining money with 50% probability. In some treatments, we give players the option to communicate intended contributions. We find that inequality reduces the prospects of reaching the target but that communication increases success dramatically. Successful groups tend to eliminate inequality over the course of the game, with rich players signaling willingness to redistribute early on. Our results suggest that coordination-promoting institutions and early redistribution from richer to poorer nations are both decisive for the avoidance of global calamities, such as disruptive climate change.

    2010-07-01

    Drug Policy and the Public Good was written by an international group of scientists from the fields of addiction, public health, criminology and policy studies to improve the linkages between drug research and drug policy. The book provides a conceptual basis for evidence-informed drug policy and describes epidemiological data on the global dimensions of drug misuse. The core of the book is a critical review of the cumulative scientific evidence in five general areas of drug policy: primary prevention programmes in schools and other settings; health and social services for drug users; attempts to control the supply of drugs, including the international treaty system; law enforcement and ventures into decriminalization; and control of the psychotropic substance market through prescription drug regimes. The final chapters discuss the current state of drug policies in different parts of the world and describe the need for future approaches to drug policy that are coordinated and informed by evidence.

  12. Effects of income redistribution on the evolution of cooperation in spatial public goods games

    2017-01-01

    Income redistribution is the transfer of income from some individuals to others directly or indirectly by means of social mechanisms, such as taxation, public services and so on. Employing a spatial public goods game, we study the influence of income redistribution on the evolution of cooperation. Two kinds of evolutionary models are constructed, which describe local and global redistribution of income respectively. In the local model, players have to pay part of their income after each PGG and the accumulated income is redistributed to the members. While in the global model, all the players pay part of their income after engaging in all the local PGGs, which are centred on himself and his nearest neighbours, and the accumulated income is redistributed to the whole population. We show that the cooperation prospers significantly with increasing income expenditure proportion in the local redistribution of income, while in the global model the situation is opposite. Furthermore, the cooperation drops dramatically from the maximum curvature point of income expenditure proportion. In particular, the intermediate critical points are closely related to the renormalized enhancement factors.

  1. Umbilical cord blood banking: public good or private benefit?

    PubMed

    2008-05-05

    Haematopoietic stem cell transplantation (HSCT) is an accepted curative therapy for many malignant and non-malignant conditions affecting children and adults. Where possible, stem cells for HSCT are provided by human leukocyte antigen (HLA)-matched, related donors. Only 30% of patients have a suitable matched donor; for other patients, donors are sought from bone marrow registries or public umbilical cord blood (UCB) banks. While public UCB banks have been established to support transplant programs in Australia and internationally, parents also have the option of storing their child's UCB in a private commercial UCB bank for personal or family use. In contrast with public UCB banks, there is little social or medical justification for private UCB banking, as it provides no benefit to the community and little benefit to parents (other than reassurance and amelioration of regret), due to the very low likelihood of requiring autologous UCB later in life. Should UCB prove to be beneficial for tissue repair or replacement in the management of degenerative disorders, such as diabetes and Parkinson's disease, then a stronger case may be made in support of commercial banking of UCB for personal use. This may have a major impact on public UCB programs.

    In an experiment we investigate preferences for allocation of a public good among group members who contributed unequally in providing the public good. Inducing the group goal of productivity resulted in preferences for equitable allocations, whereas inducing the group goals of harmony and social concern resulted in preferences for equal final outcomes. The study makes a contribution by simultaneously treating provision and allocation of a public good, thus viewing these as related processes. Another contribution is that a new paradigm is introduced that bears closer resemblance to real life public good dilemmas than previous research paradigms do. PMID:28179890

    Dysfunctional features of American penology are mitigated somewhat by the application (though uneven) of modern science. Unfortunately, these advances do not address major flaws in the ideas on which the system is erected. These include retribution, proportional punishment, and all-or-none notions of criminal responsibility. We propose abandoning retribution for its own sake; making punishment proportional to its effectiveness for behavior change rather than to the indignation evoked by the offense; and incorporating punishment into sentences based on the clinical and behavioral characteristics of the offender, including containment as necessary for public safety. Every offender would be held responsible, but the meaning and consequences thereof would change. The proposed changes could only occur incrementally. New systems of oversight and accountability would be required. Legislative bodies could provide guidelines, and courts could oversee, but neither could micromanage. Few are better qualified to work toward these goals than readers of this journal.

  6. Making abortions safe: a matter of good public health policy and practice.

    PubMed Central

    Berer, M.

    2000-01-01

    Globally, abortion mortality accounts for at least 13% of all maternal mortality. Unsafe abortion procedures, untrained abortion providers, restrictive abortion laws and high mortality and morbidity from abortion tend to occur together. Preventing mortality and morbidity from abortion in countries where these remain high is a matter of good public health policy and medical practice, and constitutes an important part of safe motherhood initiatives. This article examines the changes in policy and health service provision required to make abortions safe. It is based on a wide-ranging review of published and unpublished sources. In order to be effective, public health measures must take into account the reasons why women have abortions, the kind of abortion services required and at what stages of pregnancy, the types of abortion service providers needed, and training, cost and counselling issues. The transition from unsafe to safe abortions demands the following: changes at national policy level; abortion training for service providers and the provision of services at the appropriate primary level health service delivery points; and ensuring that women access these services instead of those of untrained providers. Public awareness that abortion services are available is a crucial element of this transition, particularly among adolescent and single women, who tend to have less access to reproductive health services generally.

    The good performance of publicly-produced health services is of vital importance, well beyond the health sector. Taking into account the great complexity of the health services in the public sector due both to their public and professional nature, we identify seven Gordian Knots as being responsible for the most frequent problems of publicly produced health services in Spain and Latin America. From the concept of good governance we take its character as a normative and ethical benchmark and its potential to renew and invigorate the government of the public sector. From comparative analysis of publicly-produced health services in the best performing countries, we extract eight characteristics which contribute significantly to good performance. A final reflection is on the relevance of the importance of offsetting the potential hostility to a reformist impulse of the status-quo with alliances that strengthen public trust and the social contract between health professionals and citizens based on the values of public health systems.

    Silver in nanoparticle form is used extensively worldwide in hospital and general practice settings, in dressings as a treatment for external wounds, burns and ulcers. Nanosilver is also an increasingly important coating over embedded medical devices, inhibiting the development of biofilm. Nanosilver disinfectant sprays and polymer coatings are being widely promoted as protective against viral infections. In addition, nanosilver is widely used for its antibacterial properties in food processing and packaging, as well as in consumer products used for domestic cleaning and clothing. This article argues that medical devices, therapeutic products, and domestic food and goods containing nanosilver, although offering therapeutic benefits, must be subject to precautionary regulation owing to associated public health and environmental risks, particularly from large volumes of nanosilver in waste water. The article first examines the use of nanosilver in a variety of contemporary medical and domestic products, the utilization of which may assist in resolving global public health problems, such as restricted access to safe food, water and medical care. It then discusses the mechanisms of toxicity for nanosilver, whether it should be classified as a new chemical entity for regulatory purposes and whether its increased usage poses significant environmental and public health risks. The article next critically analyses representative international regulatory regimes (the USA, EU, UK and Australia) for medical and domestic use of nanosilver. The conclusion includes a set of recommendations for improving international regulation of nanosilver.

  17. Defining and Developing a Global Public Health Course for Public Health Graduates

    Global public health is increasingly being seen as a speciality field within the university education of public health. However, the exact meaning of global public health is still unclear, resulting in varied curricula and teaching units among universities. The contextual differences between high- and low- and middle-income countries, and the process of globalization need to be taken into account while developing any global public health course. Global public health and public health are not separable and global public health often appears as an extension of public health in the era of globalization and interdependence. Though global public health is readily understood as health of global population, it is mainly practiced as health problems and their solutions set within low- and middle-income countries. Additional specialist competencies relevant to the context of low- and middle-income countries are needed to work in this field. Although there can be a long list of competencies relevant to this broad topic, available literature suggests that knowledge and skills related with ethics and vulnerable groups/issues; globalization and its impact on health; disease burden; culture, society, and politics; and management are important.

    Introduction At the present time, higher education institutions dealing with education for public health in Europe and beyond are faced with a complex and comprehensive task of responding to global health challenges. Review Literature reviews in public health and global health and exploration of internet presentations of regional and global organisations dealing with education for public health were the main methods employed in the work presented in this paper. Higher academic institutions are searching for appropriate strategies in competences-based education, which will increase the global attractiveness of their academic programmes and courses for continuous professional development. Academic professionals are taking advantage of blended learning and new web technologies. In Europe and beyond they are opening up debates about the scope of public health and global health. Nevertheless, global health is bringing revitalisation of public health education, which is recognised as one of the core components by many other academic institutions involved in global health work. More than ever, higher academic institutions for public health are recognising the importance of institutional partnerships with various organisations and efficient modes of cooperation in regional and global networks. Networking in a global setting is bringing new opportunities, but also opening debates about global harmonisation of competence-based education to achieve functional knowledge, increase mobility of public health professionals, better employability and affordable performance. Conclusions As public health opportunities and threats are increasingly global, higher education institutions in Europe and in other regions have to look beyond national boundaries and participate in networks for education, research and practice.

    The Google Lunar XPRIZE is igniting a new era of lunar exploration by offering the largest international incentive prize of all time. A total of $30 million in prizes are available to the first privately funded teams to safely land a robot on the surface of the Moon. Currently 23 teams are competing for the Google Lunar X PRIZE, with team headquarters spread across the world, including Germany, Hungary, Spain, Croatia, Denmark, Romania, Russia, India, Israel, Malaysia, Japan, Chile and Brazil as well as the USA. Building awareness and involving the public with the competition presents an outreach challenge on a global scale. A strong presence on social media is one of the core requirements for teams participating in the competition. To engage and inspire young people, Google Lunar XPRIZE has for the past three years run a junior version of the competition, MoonBots, a LEGO®MINDSTORMS® Challenge. A kit based on the competition has now been developed for use in Science Centres. In Autumn 2013, a full-dome planetarium show will be launched entitled 'Back to the Moon -For Good.' This show will be available to planetaria around the world at a no-cost lease. This suite of outreach activities aim to build excitement over the next two years as the teams prepare for launch before the Google Lunar XPRIZE expiry date of December 2015.

  20. "Globalized public health." A transdisciplinary comprehensive framework for analyzing contemporary globalization's influences on the field of public health.

    2009-01-01

    The current phase of globalization represents a "double-edged sword" challenge facing public health practitioners and health policy makers. The first "edge" throws light on two constructs in the field of public health: global health (formerly international health) and globalized public health. The second "edge" is that of global governance, and raises the question, "how can we construct public health regulations that adequately respond to both global and local complexities related to the two constructs mentioned earlier (global health and globalized public health)?" The two constructs call for the development of norms that will assure sustained population-wide health improvement and these two constructs have their own conceptual tools and theoretical models that permit a better understanding of them. In this paper, we introduce the "globalized public health" construct and we present an interactive comprehensive framework for critically analyzing contemporary globalization's influences on the field of public health. "Globalized public health", simultaneously a theoretical model and a conceptual framework, concerns the transformation of the field of public health in the sociohistorical context of globalization. The model is the fruit of an original theoretical research study conducted from 2005 to 2008 ("contextualized research," Gibbons' Mode II of knowledge production), founded on a QUAL-quant sequential mixed-method design. This research also reflects our political and ideological position, fuelled with aspirations of social democracy and cosmopolitical values. It is profoundly anchored in the pragmatic approach to globalization, looking to "reconcile" the market and equity. The model offers several features to users: (1) it is transdisciplinary; (2) it is interactive (CD-ROM); (3) it is nonlinear (nonlinear interrelations between the contextual globalization and the field of public health); (4) it is synchronic/diachronic (a double-crossed perspective permits

    Over the last 100 years the average temperature on the Earth has risen approximately 1ºFahrenheit (F), increasing at a rate twice as fast as has been noted for any period in the last 1,000 years. The Arctic ice cap is shrinking, glaciers are melting, and the Arctic permafrost is thawing. There is mounting evidence that these global climate changes are already affecting human health. This article provides a brief overview of global warming and climate changes, discusses effects of climate change on health, considers the factors which contribute to climate changes, and reviews individual and collective efforts related to reducing global warming.

    Traditional fiscal federalism theory postulates that devolution for the provision of local public goods increases welfare. However, most of the services offered at local level are local impure public goods whose characteristics may prevent devolution from being efficient. Our paper shows that devolution is the optimal choice only for local impure public goods. For an environment characterised by coordination and asymmetry of information problems, we propose the optimal grants-in-aid formula that Central Government should use to reduce welfare losses and we compare it with what suggested by the mainstream literature. Finally, we show under which conditions devolution should be preferred to a centralised solution. From a policy point of view, our paper may explain the heterogeneity in the choices made by countries in terms of devolution in the provision of merit and impure public goods.

    In traditional public good experiments participants receive an endowment from the experimenter that can be invested in a public good or kept in a private account. In this paper we present an experimental environment where participants can invest time during five days to contribute to a public good. Participants can make contributions to a linear public good by logging into a web application and performing virtual actions. We compared four treatments, with different group sizes and information of (relative) performance of other groups. We find that information feedback about performance of other groups has a small positive effect if we control for various attributes of the groups. Moreover, we find a significant effect of the contributions of others in the group in the previous day on the number of points earned in the current day. Our results confirm that people participate more when participants in their group participate more, and are influenced by information about the relative performance of other groups. PMID:27459070

  4. Green marketing, renewables, and free riders: increasing customer demand for a public good

    Retail electricity competition will allow customers to select their own power suppliers and some customers will make purchase decisions based, in part, on their concern for the environment. Green power marketing targets these customers under the assumption that they will pay a premium for ``green`` energy products such as renewable power generation. But renewable energy is not a traditional product because it supplies public goods; for example, a customer supporting renewable energy is unable to capture the environmental benefits that their investment provides to non-participating customers. As with all public goods, there is a risk that few customers will purchase ``green`` power and that many will instead ``free ride`` on others` participation. By free riding, an individual is able to enjoy the benefits of the public good while avoiding payment. This report reviews current green power marketing activities in the electric industry, introduces the extensive academic literature on public goods, free riders, and collective action problems, and explores in detail the implications of this literature for the green marketing of renewable energy. Specifically, the authors highlight the implications of the public goods literature for green power product design and marketing communications strategies. They emphasize four mechanisms that marketers can use to increase customer demand for renewable energy. Though the public goods literature can also contribute insights into the potential rationale for renewable energy policies, they leave most of these implications for future work (see Appendix A for a possible research agenda).

  5. The Durability of Public Goods Changes the Dynamics and Nature of Social Dilemmas

    PubMed Central

    Brown, Sam P.; Taddei, François

    2007-01-01

    An implicit assumption underpins basic models of the evolution of cooperation, mutualism and altruism: The benefits (or pay-offs) of cooperation and defection are defined by the current frequency or distribution of cooperators. In social dilemmas involving durable public goods (group resources that can persist in the environment–ubiquitous from microbes to humans) this assumption is violated. Here, we examine the consequences of relaxing this assumption, allowing pay-offs to depend on both current and past numbers of cooperators. We explicitly trace the dynamic of a public good created by cooperators, and define pay-offs in terms of the current public good. By raising the importance of cooperative history in determining the current fate of cooperators, durable public goods cause novel dynamics (e.g., transient increases in cooperation in Prisoner's Dilemmas, oscillations in Snowdrift Games, or shifts in invasion thresholds in Stag-hunt Games), while changes in durability can transform one game into another, by moving invasion thresholds for cooperation or conditions for coexistence with defectors. This enlarged view challenges our understanding of social cheats. For instance, groups of cooperators can do worse than groups of defectors, if they inherit fewer public goods, while a rise in defectors no longer entails a loss of social benefits, at least not in the present moment (as highlighted by concerns over environmental lags). Wherever durable public goods have yet to reach a steady state (for instance due to external perturbations), the history of cooperation will define the ongoing dynamics of cooperators. PMID:17611625

    2014-07-11

    The healthy public policy movement rests on the belief that a range of public policies should be at least partly informed by evidence demonstrating the positive effects of these policies on population health, health inequalities and their determinants. In order to address certain difficulties that the movement faces, knowledge produced in various scientific disciplines regarding public policies may provide some valuable guidance. In this short commentary, we examine how knowledge from the scientific disciplines investigating public policies makes it possible to address two difficulties in the development of healthy public policies: 1) adequately anticipating the effects of public policies, and 2) assessing the political viability of the policies being promoted. Since urban traffic policies are of interest to most of the other contributors to this supplement, we use examples from this field to illustrate some of our points.

    How to exploit public non-renewable resources is a public goods dilemma. Individuals can choose to limit the depletion in order to use the resource for a longer time or consume more goods to benefit themselves. When the resource is used up, there is no benefit for the future generations any more, thus the evolutionary process ends. Here we investigate what mechanisms can extend the use of resources in the framework of evolutionary game theory under two updating rules based on imitation and aspiration, respectively. Compared with imitation process, aspiration dynamics may prolong the sustainable time of a public resource.

    This updated Good Publication Practice (GPP) guideline, known as GPP3, builds on earlier versions and provides recommendations for individuals and organizations that contribute to the publication of research results sponsored or supported by pharmaceutical, medical device, diagnostics, and biotechnology companies. The recommendations are designed to help individuals and organizations maintain ethical and transparent publication practices and comply with legal and regulatory requirements. These recommendations cover publications in peer-reviewed journals and presentations (oral or poster) at scientific congresses. The International Society for Medical Publication Professionals invited more than 3000 professionals worldwide to apply for a position on the steering committee, or as a reviewer, for this guideline. The GPP2 authors reviewed all applications (n = 241) and assembled an 18-member steering committee that represented 7 countries and a diversity of publication professions and institutions. From the 174 selected reviewers, 94 sent comments on the second draft, which steering committee members incorporated after discussion and consensus. The resulting guideline includes new sections (Principles of Good Publication Practice for Company-Sponsored Medical Research, Data Sharing, Studies That Should Be Published, and Plagiarism), expands guidance on the International Committee of Medical Journal Editors' authorship criteria and common authorship issues, improves clarity on appropriate author payment and reimbursement, and expands information on the role of medical writers. By following good publication practices (including GPP3), individuals and organizations will show integrity; accountability; and responsibility for accurate, complete, and transparent reporting in their publications and presentations.

  13. Molecular and regulatory properties of a public good shape the evolution of cooperation

    Public goods cooperation abounds in nature, occurring in organisms ranging from bacteria to humans. Although previous research focused on the behavioral and ecological conditions favoring cooperation, the question of whether the molecular and regulatory properties of the public good itself can influence selection for cooperation has received little attention. Using a metapopulation model, we show that extended molecular durability of a public good—allowing multiple reuse across generations—greatly reduces selection for cheating if (and only if) the production of the public good is facultatively regulated. To test the apparent synergy between public goods durability and facultative regulation, we examined the production of iron-scavenging pyoverdin molecules by the bacterium Pseudomonas aeruginosa, a cooperative behavior that is facultatively regulated in response to iron availability. We show that pyoverdin is a very durable public good and that extended durability significantly enhances fitness. Consistent with our model, we found that nonsiderophore-producing mutants (cheats) had a relative fitness advantage over siderophore producers (cooperators) when pyoverdin durability was low but not when durability was high. This was because cooperators facultatively reduced their investment in pyoverdin production when enough pyoverdin had accumulated in the media—a cost-saving strategy that minimized the ability of cheats to invade. These findings show how molecular properties of cooperative acts can shape the costs and benefits of cooperation. PMID:20944065

  16. Cooperation and charity in spatial public goods game under different strategy update rules

    2010-03-01

    Human cooperation can be influenced by other human behaviors and recent years have witnessed the flourishing of studying the coevolution of cooperation and punishment, yet the common behavior of charity is seldom considered in game-theoretical models. In this article, we investigate the coevolution of altruistic cooperation and egalitarian charity in spatial public goods game, by considering charity as the behavior of reducing inter-individual payoff differences. Our model is that, in each generation of the evolution, individuals play games first and accumulate payoff benefits, and then each egalitarian makes a charity donation by payoff transfer in its neighborhood. To study the individual-level evolutionary dynamics, we adopt different strategy update rules and investigate their effects on charity and cooperation. These rules can be classified into two global rules: random selection rule in which individuals randomly update strategies, and threshold selection rule where only those with payoffs below a threshold update strategies. Simulation results show that random selection enhances the cooperation level, while threshold selection lowers the threshold of the multiplication factor to maintain cooperation. When charity is considered, it is incapable in promoting cooperation under random selection, whereas it promotes cooperation under threshold selection. Interestingly, the evolution of charity strongly depends on the dispersion of payoff acquisitions of the population, which agrees with previous results. Our work may shed light on understanding human egalitarianism.

    How ought public officials address policy choices that entail trade-offs between desirable public health goods? Increasing cycling improves public health both by promoting physical activity and by decreasing vehicle use, thus reducing vehicular emissions. Proponents of bicycle helmets argue that, used properly, they protect individual cyclists; however, there is concern that mandating helmet use may result in a decrease in cycling. In 2012, New York City Mayor Michael Bloomberg opposed a bicycle helmet mandate, concerned that it would have a negative impact on the city's cycling rate, which he had sought to increase. The mayor did not explain his rationale, leaving constituents unsure why he opposed the proposal. This case study underscores the challenge of creating public policy in the context of competing public health goods. PMID:24825196

  18. Why the MDGs need good governance in pharmaceutical systems to promote global health

    PubMed Central

    2014-01-01

    Background Corruption in the health sector can hurt health outcomes. Improving good governance can in turn help prevent health-related corruption. We understand good governance as having the following characteristics: it is consensus-oriented, accountable, transparent, responsive, equitable and inclusive, effective and efficient, follows the rule of law, is participatory and should in theory be less vulnerable to corruption. By focusing on the pharmaceutical system, we explore some of the key lessons learned from existing initiatives in good governance. As the development community begins to identify post-2015 Millennium Development Goals targets, it is essential to evaluate programs in good governance in order to build on these results and establish sustainable strategies. This discussion on the pharmaceutical system illuminates why. Discussion Considering pharmaceutical governance initiatives such as those launched by the World Bank, World Health Organization, and the Global Fund, we argue that country ownership of good governance initiatives is essential but also any initiative must include the participation of impartial stakeholders. Understanding the political context of any initiative is also vital so that potential obstacles are identified and the design of any initiative is flexible enough to make adjustments in programming as needed. Finally, the inherent challenge which all initiatives face is adequately measuring outcomes from any effort. However in fairness, determining the precise relationship between good governance and health outcomes is rarely straightforward. Summary Challenges identified in pharmaceutical governance initiatives manifest in different forms depending on the nature and structure of the initiative, but their regular occurrence and impact on population-based health demonstrates growing importance of addressing pharmaceutical governance as a key component of the post-2015 Millennium Development Goals. Specifically, these challenges need

  19. The coevolution of partner switching and strategy updating in non-excludable public goods game

    NASA Astrophysics Data System (ADS)

    Li, Yixiao; Shen, Bin

    2013-10-01

    Spatial public goods game is a popular metaphor to model the dilemma of collective cooperation on graphs, yet the non-excludable property of public goods has seldom been considered in previous models. Based upon a coevolutionary model where agents play public goods games and adjust their partnerships, the present model incorporates the non-excludable property of public goods: agents are able to adjust their participation in the games hosted by others, whereas they cannot exclude others from their own games. In the coevolution, a directed and dynamical network which represents partnerships among autonomous agents is evolved. We find that non-excludable property counteracts the positive effect of partner switching, i.e., the equilibrium level of cooperation is lower than that in the situation of excludable public goods game. Therefore, we study the effect of individual punishment that cooperative agents pay a personal cost to decrease benefits of those defective neighbors who participate in their hosted games. It is found that the cooperation level in the whole population is heightened in the presence of such a costly behavior.

  20. Social immunity of the family: parental contributions to a public good modulated by brood size.

    PubMed

    Duarte, Ana; Cotter, Sheena C; Reavey, Catherine E; Ward, Richard J S; De Gasperin, Ornela; Kilner, Rebecca M

    Social immunity refers to any immune defence that benefits others, besides the individual that mounts the response. Since contributions to social immunity are known to be personally costly, they are contributions to a public good. However, individuals vary in their contributions to this public good and it is unclear why. Here we investigate whether they are responding to contributions made by others with experiments on burying beetle (Nicrophorus vespilloides) families. In this species, females, males and larvae each contribute to social immunity through the application of antimicrobial exudates upon the carrion breeding resource. We show experimentally that mothers reduce their contributions to social immunity when raising large broods, and test two contrasting hypotheses to explain why. Either mothers are treating social immunity as a public good, investing less in social immunity when their offspring collectively contribute more, or mothers are trading off investment in social immunity with investment in parental care. Overall, our experiments yield no evidence to support the existence of a trade-off between social immunity and other parental care traits: we found no evidence of a trade-off in terms of time allocated to each activity, nor did the relationship between social immunity and brood size change with female condition. Instead, and consistent with predictions from models of public goods games, we found that higher quality mothers contributed more to social immunity. Therefore our results suggest that mothers are playing a public goods game with their offspring to determine their personal contribution to the defence of the carrion breeding resource.

  1. Comprehensive effective and efficient global public health surveillance.

    PubMed

    McNabb, Scott J N

    2010-12-03

    At a crossroads, global public health surveillance exists in a fragmented state. Slow to detect, register, confirm, and analyze cases of public health significance, provide feedback, and communicate timely and useful information to stakeholders, global surveillance is neither maximally effective nor optimally efficient. Stakeholders lack a globa surveillance consensus policy and strategy; officials face inadequate training and scarce resources.Three movements now set the stage for transformation of surveillance: 1) adoption by Member States of the World Health Organization (WHO) of the revised International Health Regulations (IHR[2005]); 2) maturation of information sciences and the penetration of information technologies to distal parts of the globe; and 3) consensus that the security and public health communities have overlapping interests and a mutual benefit in supporting public health functions. For these to enhance surveillance competencies, eight prerequisites should be in place: politics, policies, priorities, perspectives, procedures, practices, preparation, and payers.To achieve comprehensive, global surveillance, disparities in technical, logistic, governance, and financial capacities must be addressed. Challenges to closing these gaps include the lack of trust and transparency; perceived benefit at various levels; global governance to address data power and control; and specified financial support from globa partners.We propose an end-state perspective for comprehensive, effective and efficient global, multiple-hazard public health surveillance and describe a way forward to achieve it. This end-state is universal, global access to interoperable public health information when it's needed, where it's needed. This vision mitigates the tension between two fundamental human rights: first, the right to privacy, confidentiality, and security of personal health information combined with the right of sovereign, national entities to the ownership and stewardship

  2. Chicago neoliberalism versus Cowles planning: perspectives on patents and public goods in Cold War economic thought.

    Van Horn, Robert; Klaes, Matthias

    2011-01-01

    In post-Sputnik America, when many policymakers and social scientists feared the Soviet Union had a technological advantage over the United States, assessing the relative importance of patents for inventive activity and examining whether scientific research constituted a public good were paramount concerns. The neoliberals of the University of Chicago and the planners of the Cowles Commission both spoke to these issues. This paper sheds light on their views on patents and public goods in the late 1950s and early 1960s by examining representatives of Cowles and Chicago, Kenneth Arrow and Ronald Coase, respectively. Furthermore, it evaluates whether their views on patents and public goods clashed with the interests of RAND, at which both Arrow and Coase worked at some point during this time period. The paper argues that the Chicago-neoliberal position of Coase undermined the interests of RAND, while the Cowles-planning conclusions of Arrow furthered those interests.

Governments should thus oversee and fund clinical trials as the public good that they are. Clinical tests should be awarded to the most qualified scientists through a competitive process, financed in part with the decrease in drug costs to governmental health care programs and in part with drug developers' contributions, selected to maximize social benefit, and made global via intergovernmental bodies to maximize social return. This would reduce the cost of redundant investigations to the global public health system, lower supply costs to drug consumers, and lower the breakeven point for investment in research to discover new drugs.

Clinical tests should be awarded to the most qualified scientists through a competitive process, financed in part with the decrease in drug costs to governmental health care programs and in part with drug developers’ contributions, selected to maximize social benefit, and made global via intergovernmental bodies to maximize social return. This would reduce the cost of redundant investigations to the global public health system, lower supply costs to drug consumers, and lower the breakeven point for investment in research to discover new drugs.

    Our society is addicted to steel. Global demand for steel has risen to 1.4 billion tonnes a year and is set to at least double by 2050, while the steel industry generates nearly a 10th of the world's energy related CO₂ emissions. Meeting our 2050 climate change targets would require a 75% reduction in CO₂ emissions for every tonne of steel produced and finding credible solutions is proving a challenge. The starting point for understanding the environmental impacts of steel production is to accurately map the global steel supply chain and identify the biggest steel flows where actions can be directed to deliver the largest impact. In this paper we present a map of global steel, which for the first time traces steel flows from steelmaking, through casting, forming, and rolling, to the fabrication of final goods. The diagram reveals the relative scale of steel flows and shows where efforts to improve energy and material efficiency should be focused.

  8. Good and Bad Research Collaborations: Researchers’ Views on Science and Ethics in Global Health Research

    2016-01-01

    There has been a dramatic rise in the scale and scope of collaborative global health research. A number of structural and scientific factors explain this growth and there has been much discussion of these in the literature. Little, if any, attention has been paid, however, to the factors identified by scientists and other research actors as important to successful research collaboration. This is surprising given that their decisions are likely to play a key role in the sustainability and effectiveness of global health research initiatives. In this paper, we report on qualitative research with leading scientists involved in major international research collaborations about their views on good and bad collaborations and the factors that inform their decision-making about joining and participating actively in research networks. We identify and discuss eight factors that researchers see as essential in judging the merits of active participation in global health research collaborations: opportunities for active involvement in cutting-edge, interesting science; effective leadership; competence of potential partners in and commitment to good scientific practice; capacity building; respect for the needs, interests and agendas of partners; opportunities for discussion and disagreement; trust and confidence; and, justice and fairness in collaboration. Our findings suggest that the sustainability and effectiveness of global health research collaborations has an important ethical or moral dimension for the research actors involved. PMID:27737006

  11. Cooperation among cancer cells as public goods games on Voronoi networks.

    PubMed

    Archetti, Marco

    2016-05-07

    Cancer cells produce growth factors that diffuse and sustain tumour proliferation, a form of cooperation that can be studied using mathematical models of public goods in the framework of evolutionary game theory. Cell populations, however, form heterogeneous networks that cannot be described by regular lattices or scale-free networks, the types of graphs generally used in the study of cooperation. To describe the dynamics of growth factor production in populations of cancer cells, I study public goods games on Voronoi networks, using a range of non-linear benefits that account for the known properties of growth factors, and different types of diffusion gradients. The results are surprisingly similar to those obtained on regular graphs and different from results on scale-free networks, revealing that network heterogeneity per se does not promote cooperation when public goods diffuse beyond one-step neighbours. The exact shape of the diffusion gradient is not crucial, however, whereas the type of non-linear benefit is an essential determinant of the dynamics. Public goods games on Voronoi networks can shed light on intra-tumour heterogeneity, the evolution of resistance to therapies that target growth factors, and new types of cell therapy.

  15. Eco-evolutionary feedbacks between private and public goods: evidence from toxic algal blooms.

    PubMed

    Driscoll, William W; Hackett, Jeremiah D; Ferrière, Régis

    2016-01-01

    The importance of 'eco-evolutionary feedbacks' in natural systems is currently unclear. Here, we advance a general hypothesis for a particular class of eco-evolutionary feedbacks with potentially large, long-lasting impacts in complex ecosystems. These eco-evolutionary feedbacks involve traits that mediate important interactions with abiotic and biotic features of the environment and a self-driven reversal of selection as the ecological impact of the trait varies between private (small scale) and public (large scale). Toxic algal blooms may involve such eco-evolutionary feedbacks due to the emergence of public goods. We review evidence that toxin production by microalgae may yield 'privatised' benefits for individual cells or colonies under pre- and early-bloom conditions; however, the large-scale, ecosystem-level effects of toxicity associated with bloom states yield benefits that are necessarily 'public'. Theory predicts that the replacement of private with public goods may reverse selection for toxicity in the absence of higher level selection. Indeed, blooms often harbor significant genetic and functional diversity: bloom populations may undergo genetic differentiation over a scale of days, and even genetically similar lineages may vary widely in toxic potential. Intriguingly, these observations find parallels in terrestrial communities, suggesting that toxic blooms may serve as useful models for eco-evolutionary dynamics in nature. Eco-evolutionary feedbacks involving the emergence of a public good may shed new light on the potential for interactions between ecology and evolution to influence the structure and function of entire ecosystems.

  16. Evolutionary dynamics of interlinked public goods traits: an experimental study of siderophore production in Pseudomonas aeruginosa.

    2015-01-01

    Public goods cooperation is common in microbes, and there is much interest in understanding how such traits evolve. Research in recent years has identified several important factors that shape the evolutionary dynamics of such systems, yet few studies have investigated scenarios involving interactions between multiple public goods. Here, we offer general predictions about the evolutionary trajectories of two public goods traits having positive, negative or neutral regulatory influence on one another's expression, and we report on a test of some of our predictions in the context of Pseudomonas aeruginosa's production of two interlinked iron-scavenging siderophores. First, we confirmed that both pyoverdine and pyochelin siderophores do operate as public goods under appropriate environmental conditions. We then tracked their production in lines experimentally evolved under different iron-limitation regimes known to favour different siderophore expression profiles. Under strong iron limitation, where pyoverdine represses pyochelin, we saw a decline in pyoverdine and a concomitant increase in pyochelin - consistent with expansion of pyoverdine-defective cheats derepressed for pyochelin. Under moderate iron limitation, pyochelin declined - again consistent with an expected cheat invasion scenario - but there was no concomitant shift in pyoverdine because cross-suppression between the traits is unidirectional only. Alternating exposure to strong and moderate iron limitation caused qualitatively similar though lesser shifts compared to the constant-environment regimes. Our results confirm that the regulatory interconnections between public goods traits can significantly modulate the course of evolution, yet also suggest how we can start to predict the impacts such complexities will have on phenotypic divergence and community stability.

  17. Goodness of regularity in dot patterns: global symmetry, local symmetry, and their interactions.

    PubMed

    2007-01-01

    Goodness is a classic Gestalt notion defined as salience or perceptual strength of a given pattern. All operational models of goodness have assigned a central role to mirror symmetry but not much attention has been paid to the distinction between global and local mirror symmetry, and their possible interactions. We designed eight different types of dot patterns (all consisting of 80 dots), combining different numbers (0, 1, and 2) and relative orientations (parallel or orthogonal to each other) of local and global axes of symmetry (affecting 50% or 100% of the dots, respectively) at different absolute orientations (vertical and horizontal). Each of 640 trials consisted of a short presentation of a new dot pattern, which subjects had to classify as regular or random. We hypothesised that the overall goodness of patterns is not the simple sum of the amount of regularity present in them but depends on the cooperation and competition between symmetries. The results confirmed our hypothesis, showing that performance in this regularity-detection task did not increase in a linear way when some symmetries were added to other symmetries.

  18. Volunteering leads to rock-paper-scissors dynamics in a public goods game

    Collective efforts are a trademark of both insect and human societies. They are achieved through relatedness in the former and unknown mechanisms in the latter. The problem of achieving cooperation among non-kin has been described as the `tragedy of the commons', prophesying the inescapable collapse of many human enterprises. In public goods experiments, initial cooperation usually drops quickly to almost zero. It can be maintained by the opportunity to punish defectors or the need to maintain good reputation. Both schemes require that defectors are identified. Theorists propose that a simple but effective mechanism operates under full anonymity. With optional participation in the public goods game, `loners' (players who do not join the group), defectors and cooperators will coexist through rock-paper-scissors dynamics. Here we show experimentally that volunteering generates these dynamics in public goods games and that manipulating initial conditions can produce each predicted direction. If, by manipulating displayed decisions, it is pretended that defectors have the highest frequency, loners soon become most frequent, as do cooperators after loners and defectors after cooperators. On average, cooperation is perpetuated at a substantial level.

    We have asked whether the strategic purpose of the tobacco industry is something that a public resource, such as UK Biobank, should support. Tobacco industry health research has been known to work irreconcilably with the purposes of such institutions, which can be surmised as for the public good and defined to improve the provision, diagnosis, and treatment of illness and the promotion of health throughout society. We have isolated possible conflicts of interest that underlie vested research agendas of the tobacco industry and that may extend to tobacco industry–funded researchers. With respect to research, we find that the tobacco industry is entirely at odds with the purposes of public biobanking. PMID:25122018

    Regulatory science plays a vital role in protecting and promoting global public health by providing the scientific basis for ensuring that food and medical products are safe, properly labeled, and effective. Regulatory science research was first developed for the determination of product safety in the early part of the 20th Century, and continues to support innovation of the processes needed for regulatory policy decisions. Historically, public health laws and regulations were enacted following public health tragedies, and often the research tools and techniques required to execute these laws lagged behind the public health needs. Throughout history, similar public health problems relating to food and pharmaceutical products have occurred in countries around the world, and have usually led to the development of equivalent solutions. For example, most countries require a demonstration of pharmaceutical safety and efficacy prior to marketing these products using approaches that are similar to those initiated in the United States. The globalization of food and medical products has created a shift in regulatory compliance such that gaps in food and medical product safety can generate international problems. Improvements in regulatory research can advance the regulatory paradigm toward a more preventative, proactive framework. These improvements will advance at a greater pace with international collaboration by providing additional resources and new perspectives for approaching and anticipating public health problems. The following is a review of how past public health disasters have shaped the current regulatory landscape, and where innovation can facilitate the shift from reactive policies to proactive policies.

    Maintaining the Earth's climate within habitable boundaries is probably the greatest "public goods game" played by humans. However, with >6 billion "players" taking part, the game seems to rule out individual altruistic behavior. Thus, climate protection is a problem of sustaining a public resource that everybody is free to overuse, a "tragedy of the commons" problem that emerges in many social dilemmas. We perform a previously undescribed type of public goods experiment with human subjects contributing to a public pool. In contrast to the standard protocol, here the common pool is not divided among the participants; instead, it is promised that the pool will be invested to encourage people to reduce their fossil fuel use. Our extensive experiments demonstrate that players can behave altruistically to maintain the Earth's climate given the right set of circumstances. We find a nonzero basic level of altruistic behavior, which is enhanced if the players are provided with expert information describing the state of knowledge in climate research. Furthermore, personal investments in climate protection increase substantially if players can invest publicly, thus gaining social reputation. This increase occurs because subjects reward other subjects' contributions to sustaining the climate, thus reinforcing their altruism. Therefore, altruism may convert to net personal benefit and to relaxing the dilemma if the gain in reputation is large enough. Our finding that people reward contributions to sustaining the climate of others is a surprising result. There are obvious ways these unexpected findings can be applied on a large scale.

    In this paper, we discuss qualitative research for public health professionals. Quality matters in qualitative research, but the principles by which it is judged are critically different from those used to judge epidemiology. Compared to quantitative research, good quality qualitative studies serve different aims, answer distinct research questions and have their own logic for sampling, data collection and analysis. There is, however, no need for antagonism between qualitative research and epidemiology; the two are complementary. With theoretical and methodological guidance from experienced qualitative researchers, public health professionals can learn how to make the most of qualitative research for themselves.

    In public health, the generation, management, and transfer of knowledge all need major improvement. Problems in generating knowledge include an imbalance in research funding, publication bias, unnecessary studies, adherence to fashion, and undue interest in novel and immediate issues. Impaired generation of knowledge, combined with a dated and inadequate process for managing knowledge and an inefficient system for transferring knowledge, mean a distorted body of evidence available for decisionmaking in public health. This article hopes to stimulate discussion by proposing a Global Registry of Anticipated Public Health Studies. This prospective, comprehensive system for tracking research in public health could help enhance collaboration and improve efficiency. Practical problems must be discussed before such a vision can be further developed. PMID:17413073

  6. Evolution of cooperation in spatial public goods games with common resource dynamics.

    PubMed

    Wakano, Joe Yuichiro

    2007-08-21

    Investment in a common resource shared by all players is difficult to evolve despite higher returns because a non-investor (free-rider) always receives more than an investor (altruist). This situation is referred to as the Tragedy of the Commons and is often observed in various biological systems including environmental problems of human society. Punishment and reputation are effective mechanisms but require cooperator's ability to identify free-riders. Volunteering can work in anonymous public goods games but this requires voluntary participation, which is not always the case. Here, we show that the evolution of altruism is possible in anonymous and obligate public goods games if we consider the spatiotemporal dynamics of the common resource that incorporate spatial diffusion and internal dynamics of the commons. The investors' strategy to counter free-riders is to increase population density and to outnumber them with the common resource level kept as low as that of the free-riders.

    The tragedy of the commons predicts social collapse when public goods are jointly exploited by individuals attempting to maximize their fitness at the expense of other social group members. However, animal societies have evolved many times despite this vulnerability to exploitation by selfish individuals. Kin selection offers a solution to this social dilemma, but in large social groups mean relatedness is often low. Sociable weavers (Philetairus socius) live in large colonies that share the benefits of a massive communal nest, which requires individual investment for construction and maintenance. Here, we show that despite low mean kinship within colonies, relatives are spatially and socially clustered and that nest-building males have higher local relatedness to other colony members than do non-building males. Alternative hypotheses received little support, so we conclude that the benefits of the public good are shared with kin and that cooperative investment is, despite the large size and low relatedness of these communities, kin directed.

    The efficiency of institutionalized punishment is studied by evaluating the stationary states in the spatial public goods game comprising unconditional defectors, cooperators, and cooperating pool punishers as the three competing strategies. Fines and costs of pool punishment are considered as the two main parameters determining the stationary distributions of strategies on the square lattice. Each player collects a payoff from five five-person public goods games, and the evolution of strategies is subsequently governed by imitation based on pairwise comparisons at a low level of noise. The impact of pool punishment on the evolution of cooperation in structured populations is significantly different from that reported previously for peer punishment. Representative phase diagrams reveal remarkably rich behavior, depending also on the value of the synergy factor that characterizes the efficiency of investments payed into the common pool. Besides traditional single- and two-strategy stationary states, a rock-paper-scissors type of cyclic dominance can emerge in strikingly different ways.

    Group interactions on structured populations can be represented by the public goods game on networks. During the evolutionary games, selective investment mechanism fosters social cooperative behavior. First we focus on star-like graphs to provide some light on why selective investment mechanism can promote collective cooperation. Then we implement public goods game with this mechanism on scale free networks to investigate behavior properties of individuals within different social environments. We indicate that high-degree nodes are predominantly inert owning largely to their satisfaction with their status, while low-degree nodes are very active due to their strive towards higher prosperity. Besides, we introduce the Gini coefficient to describe social inequality and find that large multiply factor r favors social fairness. Our work is applicable for community supervision and social wealth regulation.

  13. Punishment in public goods games leads to meta-stable phase transitions and hysteresis

    NASA Astrophysics Data System (ADS)

    Hintze, Arend; Adami, Christoph

    2015-07-01

    The evolution of cooperation has been a perennial problem in evolutionary biology because cooperation can be undermined by selfish cheaters who gain an advantage in the short run, while compromising the long-term viability of the population. Evolutionary game theory has shown that under certain conditions, cooperation nonetheless evolves stably, for example if players have the opportunity to punish cheaters that benefit from a public good yet refuse to pay into the common pool. However, punishment has remained enigmatic because it is costly and difficult to maintain. On the other hand, cooperation emerges naturally in the public goods game if the synergy of the public good (the factor multiplying the public good investment) is sufficiently high. In terms of this synergy parameter, the transition from defection to cooperation can be viewed as a phase transition with the synergy as the critical parameter. We show here that punishment reduces the critical value at which cooperation occurs, but also creates the possibility of meta-stable phase transitions, where populations can ‘tunnel’ into the cooperating phase below the critical value. At the same time, cooperating populations are unstable even above the critical value, because a group of defectors that are large enough can ‘nucleate’ such a transition. We study the mean-field theoretical predictions via agent-based simulations of finite populations using an evolutionary approach where the decisions to cooperate or to punish are encoded genetically in terms of evolvable probabilities. We recover the theoretical predictions and demonstrate that the population shows hysteresis, as expected in systems that exhibit super-heating and super-cooling. We conclude that punishment can stabilize populations of cooperators below the critical point, but it is a two-edged sword: it can also stabilize defectors above the critical point.

  14. Adaptive evolution of cooperation through Darwinian dynamics in Public Goods games.

    Deng, Kuiying; Chu, Tianguang

    2011-01-01

    The linear or threshold Public Goods game (PGG) is extensively accepted as a paradigmatic model to approach the evolution of cooperation in social dilemmas. Here we explore the significant effect of nonlinearity of the structures of public goods on the evolution of cooperation within the well-mixed population by adopting Darwinian dynamics, which simultaneously consider the evolution of populations and strategies on a continuous adaptive landscape, and extend the concept of evolutionarily stable strategy (ESS) as a coalition of strategies that is both convergent-stable and resistant to invasion. Results show (i) that in the linear PGG contributing nothing is an ESS, which contradicts experimental data, (ii) that in the threshold PGG contributing the threshold value is a fragile ESS, which cannot resist the invasion of contributing nothing, and (iii) that there exists a robust ESS of contributing more than half in the sigmoid PGG if the return rate is relatively high. This work reveals the significant effect of the nonlinearity of the structures of public goods on the evolution of cooperation, and suggests that, compared with the linear or threshold PGG, the sigmoid PGG might be a more proper model for the evolution of cooperation within the well-mixed population.

  15. Competition between species can stabilize public-goods cooperation within a species

    Celiker, Hasan; Gore, Jeff

    2012-01-01

    Competition between species is a major ecological force that can drive evolution. Here, we test the effect of this force on the evolution of cooperation within a species. We use sucrose metabolism of budding yeast, Saccharomyces cerevisiae, as a model cooperative system that is subject to social parasitism by cheater strategies. We find that when cocultured with a bacterial competitor, Escherichia coli, the frequency of cooperator phenotypes in yeast populations increases dramatically as compared with isolated yeast populations. Bacterial competition stabilizes cooperation within yeast by limiting the yeast population density and also by depleting the public goods produced by cooperating yeast cells. Both of these changes induced by bacterial competition increase the cooperator frequency because cooperator yeast cells have a small preferential access to the public goods they produce; this preferential access becomes more important when the public good is scarce. Our results indicate that a thorough understanding of species interactions is crucial for explaining the maintenance and evolution of cooperation in nature. PMID:23149686

  16. Punishment Mechanism with Self-Adjusting Rules in Spatial Voluntary Public Goods Games

    The phenomena of cooperation in animal and human society are ubiquitous, but the selfish outcome that no player contributes to the public good will lead to the “tragedy of the commons”. The recent research shows that high punishment can improve the cooperation of the population. In this paper, we introduce a punishment mechanism into spatial voluntary public goods games with every individual only knowing his own payoff in each round. Using the self-adjusting rules, we find that the different cost for punishment can lead to different effects on the voluntary public goods games. Especially, when the cost for punishment is decreased, a higher contribution region will appear in the case of low r value. It means even for the low r value, individuals can form the contributing groups in large quantities to produce a more efficient outcome than that in moderate r value. In addition, we also find the players' memory can have effects on the average outcome of the population.

    2016-03-01

    Altruistic behaviors in multiplayer groups have obtained great attention in the context of the public goods game, which poses a riddle from the evolutionary viewpoint. Here we focus on a particular type of public goods game model in which the benefits of cooperation are either discounted or synergistically enhanced at the appearance of multiple cooperators in a group. Moreover, we focus on the three-strategies profile by adding the role of loners, besides the often-used cooperation and defection. Using the replicator dynamic equations, we investigate a range of dynamical portraits that characterizes the properties of the steady state. Analysis results indicate that loners and cooperators both have chances to be the stable equilibrium points in the presence of perturbations, while defectors fail to do so in this three-strategy competition.

    The persistence of cooperation in public goods situations has become an important puzzle for researchers. This paper considers the threshold public goods games where the option of insurance is provided for players from the standpoint of diversification of risk, envisaging the possibility of multiple strategies in such scenarios. In this setting, the provision point is defined in terms of the minimum number of contributors in one threshold public goods game, below which the game fails. In the presence of risk and insurance, more contributions are motivated if (1) only cooperators can opt to be insured and thus their contribution loss in the aborted games can be (partly or full) covered by the insurance; (2) insured cooperators obtain larger compensation, at lower values of the threshold point (the required minimum number of contributors). Moreover, results suggest the dominance of insured defectors who get a better promotion by more profitable benefits from insurance. We provide results of extensive computer simulations in the realm of spatial games (random regular networks and scale-free networks here), and support this study with analytical results for well-mixed populations. Our study is expected to establish a causal link between the widespread altruistic behaviors and the existing insurance system.

    Altruistic behaviors in multiplayer groups have obtained great attention in the context of the public goods game, which poses a riddle from the evolutionary viewpoint. Here we focus on a particular type of public goods game model in which the benefits of cooperation are either discounted or synergistically enhanced at the appearance of multiple cooperators in a group. Moreover, we focus on the three-strategies profile by adding the role of loners, besides the often-used cooperation and defection. Using the replicator dynamic equations, we investigate a range of dynamical portraits that characterizes the properties of the steady state. Analysis results indicate that loners and cooperators both have chances to be the stable equilibrium points in the presence of perturbations, while defectors fail to do so in this three-strategy competition. Moreover, the coexistence state, in which all three strategies exist in equilibrium, can be led by suitable parameters and stabilized for perturbations. These results elucidate the interplay between the characteristics of the public goods game and evolutionary dynamics in well-mixed systems.

  20. The public goods game with a new form of shared reward

    2016-10-01

    Altruistic contribution to a common good evenly enjoyed by all group members is hard to explain because of the greater benefits obtained by a defector than a cooperator. A variety of mechanisms have been proposed to resolve the collective dilemma over the years, including rewards for altruism. An underrated and easily ignored phenomenon is that the altruistic behaviors of cooperators not only directly enhance the benefits of their game opponents, but also indirectly produce good influences to other allied members in their surroundings (e.g. relatives or friends). Here we propose a shared reward, in the form of extensive benefits, to extend the traditional definition of the public goods game. Mathematical analysis using the Moran process helps us to obtain the fixation probability for one ‘mutant’ cooperator to invade and dominate the whole defecting population. Results suggest that a tunable parameter exists, above a certain critical value of which natural selection favors cooperation over defection. In addition, analytical results with replicator dynamics show that this critical value influencing the evolution of altruism is closely correlated with the population size, the gaming group size and the synergy factor of the public goods game. These results, based on an extended notion of shared reward and extensive benefits, are expected to provide novel explanations for the emergence of altruistic behaviors.

    The editors of medical journals should take the steps necessary to assure its readers that the contents of their publications are based in true data, that they are original and fulfill the ethical rules of biomedical and clinical research, including its reporting. This editors role has become increasingly difficult since the pressure to publish scientific papers is progressively stimulated by the role that those papers play in curricula vitae when the authors apply for university positions, academic promotions, research grants and for their personal prestige. As a consequence, increasing instances of misconduct in scientific publications are detected. Some cases are noticed during the editorial process, mostly when peer reviewers identify redundant publications or plagiarism. Other cases are denounced after a manuscript was published. It is the editors duty to verify the misconduct, request an explanation from the authors and, if their answer is unsatisfactory, report the problem to the institutional authorities supporting the authors. The editors should denounce the situation in a forthcoming issue of the journal. Universities should enforce the teaching of ethical rules that govern the report of scientific information. Revista Médica de Chile follows recommendations given by the International Committee of Medical Journal Editors, the World Association of Medical Editors and other groups, but honesty and good faith in all the actors involved in the process of biomedical publications (authors, reviewers, editors) remain the cornerstones of scientific good behavior.

Public health professionals need to be aware that the "sound science" movement is not an indigenous effort from within the profession to improve the quality of scientific discourse, but reflects sophisticated public relations campaigns controlled by industry executives and lawyers whose aim is to manipulate the standards of scientific proof to serve the corporate interests of their clients.

    Prospects have never seemed better for a truly global approach to science to improve human health, with leaders of national initiatives laying out their vision of a worldwide network of related projects. An extensive literature addresses obstacles to global genomic data sharing, yet a series of public polls suggests that the scientific community may be overlooking a significant barrier: potential public resistance to data sharing across national borders. In several large United States surveys, university researchers in other countries were deemed the least acceptable group of data users, and a just-completed US survey found a marked increase in privacy and security concerns related to data access by non-US researchers. Furthermore, diminished support for sharing beyond national borders is not unique to the US, although the limited data from outside the US suggest variation across countries as well as demographic groups. Possible sources of resistance include apprehension about privacy and security protections. Strategies for building public support include making the affirmative case for global data sharing, addressing privacy, security, and other legitimate concerns, and investigating public concerns in greater depth.

  6. Exploring the international arena of global public health surveillance.

    2007-01-01

    Threats posed by new, emerging or re-emerging communicable diseases are taking a global dimension, to which the World Health Organization (WHO) Secretariat has been responding with determination since 1995. Key to the global strategy for tackling epidemics across borders is the concept of global public health surveillance, which has been expanded and formalized by WHO and its technical partners through a number of recently developed instruments and initiatives. The adoption by the 58th World Health Assembly of the revised (2005) International Health Regulations provides the legal framework for mandating countries to link and coordinate their action through a universal network of surveillance networks. While novel environmental threats and outbreak-prone diseases have been increasingly identified during the past three decades, new processes of influence have appeared more recently, driven by the real or perceived threats of bio-terrorism and disruption of the global economy. Accordingly, the global surveillance agenda is being endorsed, and to some extent seized upon by new actors representing security and economic interests. This paper explores external factors influencing political commitment to comply with international health regulations and it illustrates adverse effects generated by: perceived threats to sovereignty, blurred international health agendas, lack of internationally recognized codes of conduct for outbreak investigations, and erosion of the impartiality and independence of international agencies. A companion paper (published in this issue) addresses the intrinsic difficulties that health systems of low-income countries are facing when submitted to the ever-increasing pressure to upgrade their public health surveillance capacity.

    Human activities are placing enormous pressures on the biosphere. The introduction of new chemicals and the increasing ambient levels of existing chemicals have resulted in atmospheric degradation. This paper reviews some of the adverse effects of stratospheric ozone depletion and global warming. Because the atmospheric effects of ozone depletion are fairly well characterized, quantitative risk estimates have been developed. However, because the atmospheric effects of global warming are less understood, public health problems that could be intensified by climate change are assessed qualitatively. The interactive effects of these two phenomena are also discussed.

    In landscapes where private land tenure is prevalent, public funds for ecological landscape restoration are sometimes spent subsidising the revegetation of cleared land, and the protection of remnant vegetation from livestock. However, the total area treated may be unclear because such projects are not always recorded, and landholders may undertake similar activities without subsidisation. In the absence of empirical data, in the state of Victoria, Australia, a reporting assumption has been employed that suggests that wholly privately funded sites match publicly subsidised sites on a hectare for hectare basis (a so-called "x2" assumption). Conversely, the "crowding out" theory of investment in public goods such as environmental benefits suggests that public investment may supplant private motivation. Using aerial photography we mapped the extent of revegetation, native vegetation fencing and restoration on 71 representative landholdings in rural south-eastern Australia. We interviewed each landholder and recorded the age and funding model of each site. Contrary to the local "x2" reporting assumption, about 75% of the total area of the 412 sites was from subsidised sites, and that proportion was far higher for the period after 1997. However, rather than displacing unsubsidised activity, our modelling showed that landholders who had recently been subsidised for a project were more likely to have subsequently completed unsubsidised work. This indicates that, at least in terms of medium-term economic impact, the large increase in public subsidies did not diminish privately funded activity, as might be expected according to the theory of crowding out.

    The eradication of smallpox owes its success first and foremost to the thousands of lay health workers and community members who, throughout the campaign and across continents, took on the roles of advocates, educators, vaccinators, care providers and contributors to epidemic surveillance and containment. Bangladesh provides a good example where smallpox eradication and the capacity enhancement needed to achieve this goal resulted in a two-way mutually beneficial process. Smallpox-dedicated staff provided community members with information guidance, support and tools. In turn, communities not only created the enabling environment for smallpox program staff to perform their work but acquired the capacity to perform essential eradication tasks. Contemporary global health programmes can learn much from these core lessons including: the pivotal importance of supporting community aspirations, capacity and resilience; the critical need to enhance commitment, capacity and accountability across the workforce; and the high value of attentive human resources management and support. We owe to subsequent global disease control, elimination and eradication ventures recognition of the need for social and behavioural science to inform public health strategies; the essential roles that civil society organizations and public-private partnerships can play in public health discourse and action; the overall necessity of investing in broad-based health system strengthening; and the utility of applying human rights principles, norms and standards to public health policy and practice.

    The need for public-private partnerships arose against the backdrop of inadequacies on the part of the public sector to provide public good on their own, in an efficient and effective manner, owing to lack of resources and management issues. These considerations led to the evolution of a range of interface arrangements that brought together organizations with the mandate to offer public good on one hand, and those that could facilitate this goal though the provision of resources, technical expertise or outreach, on the other. The former category includes of governments and intergovernmental agencies and the latter, the non-profit and for-profit private sector. Though such partnerships create a powerful mechanism for addressing difficult problems by leveraging on the strengths of different partners, they also package complex ethical and process-related challenges. The complex transnational nature of some of these partnership arrangements necessitates that they be guided by a set of global principles and norms. Participation of international agencies warrants that they be set within a comprehensive policy and operational framework within the organizational mandate and involvement of countries requires legislative authorization, within the framework of which, procedural and process related guidelines need to be developed. This paper outlines key ethical and procedural issues inherent to different types of public-private arrangements and issues a Global Call to Action. PMID:15282025

    Many microbes cooperatively secrete extracellular products that favorably modify their environment. Consistent with social evolution theory, structured habitats play a role in maintaining these traits in microbial model systems, by localizing the benefits and separating strains that invest in these products from 'cheater' strains that benefit without paying the cost. It is thus surprising that many unicellular, well-mixed microalgal populations invest in extracellular toxins that confer ecological benefits upon the entire population, for example, by eliminating nutrient competitors (allelopathy). Here we test the hypotheses that microalgal exotoxins are (1) exploitable public goods that benefit all cells, regardless of investment, or (2) nonexploitable private goods involved in cell-level functions. We test these hypotheses with high-toxicity (TOX+) and low-toxicity (TOX-) strains of the damaging, mixotrophic microalga Prymnesium parvum and two common competitors: green algae and diatoms. TOX+ actually benefits from dense populations of competing green algae, which can also be prey for P. parvum, yielding a relative fitness advantage over coexisting TOX-. However, with nonprey competitors (diatoms), TOX- increases in frequency over TOX+, despite benefiting from the exclusion of diatoms by TOX+. An evolutionary unstable, ecologically devastating public good may emerge from traits selected at lower levels expressed in novel environments.

    In a community-structured population, public goods games (PGG) occur both within and between communities. Such type of PGG is referred as multilevel public goods games (MPGG). We propose a minimalist evolutionary model of the MPGG and analytically study the evolution of cooperation. We demonstrate that in the case of sufficiently large community size and community number, if the imitation strength within community is weak, i.e., an individual imitates another one in the same community almost randomly, cooperation as well as punishment are more abundant than defection in the long run; if the imitation strength between communities is strong, i.e., the more successful strategy in two individuals from distinct communities is always imitated, cooperation and punishment are also more abundant. However, when both of the two imitation intensities are strong, defection becomes the most abundant strategy in the population. Our model provides insight into the investigation of the large-scale cooperation in public social dilemma among contemporary communities.

    Behavior is a major determinant of health, but changes in individual conduct are difficult, and health promotion lacks effectiveness. State intervention in the last century, rooted in the modernist movement, went far beyond dealing with externalities and built the framework of the welfare state. The crisis of the welfare state and post modernity after the 1970s led to a weakness of ideologies and values, narcissistic individualism, and lack of trust in institutions, all of which hampered the ability of society's perspective to influence individual behavior. A review of health economics (especially merit goods) and public health (ethics and values of health promotion and prevention) may be useful to understand certain dilemmas in the balance between public intervention and individual autonomy. Given that many unhealthy decisions come from biased or irrational individual preferences, a promising new field in public health interventions is being developed, known as , or, more appropriately, as goods>, which allow society to selectively influence those individuals whose decision biases lead to self-harming behavior, without constraining the autonomy of well informed autonomous individuals (even though their preferences may not coincide with society's recommended preferences).

    2012-01-01

    Globalisation is a defining economic and social trend of the past several decades. Globalisation affects health directly and indirectly and creates economic and health disparities within and across countries. The political response to address these disparities, exemplified by the Millennium Development Goals, has put pressure on the global community to redress massive inequities in health and other determinants of human capability across countries. This, in turn, has accelerated a transformation in the architecture of global health governance. The entrance of new actors, such as private foundations and multi-stakeholder initiatives, contributed to a doubling of funds for global health between 2000 and 2010. Today the governance of public health is in flux, with diminished leadership from multilateral institutions, such as the WHO, and poor coherence in policy and programming that undermines the potential for sustainable health gains. These trends pose new challenges and opportunities for global public health, which is centrally concerned with identifying and addressing threats to the health of vulnerable populations worldwide.

    Empirical research shows that good waste management practice in South Africa is not always under the volitional control of those tasked with its implementation. While intention to act may exist, external factors, within the distal and proximal context, create barriers to waste behaviour. In addition, these barriers differ for respondents in municipalities, private industry and private waste companies. The main barriers to implementing good waste management practice experienced by respondents in municipalities included insufficient funding for waste management and resultant lack of resources; insufficient waste knowledge; political interference in decision-making; a slow decision-making process; lack of perceived authority to act by waste staff; and a low priority afforded to waste. Barriers experienced by respondents in private industry included insufficient funding for waste and the resultant lack of resources; insufficient waste knowledge; and government bureaucracy. Whereas, barriers experienced in private waste companies included increasing costs; government bureaucracy; global markets; and availability of waste for recycling. The results suggest that respondents in public and private waste organizations are subject to different structural forces that shape, enable and constrain waste behaviour.

    2013-11-01

    Increasing complexity is following in the wake of rampant globalization. Thus, the discussion about Sustainable Development Goals (SDGs) requires new thinking that departs from a critique of current policy tools in exploration of a complexity-friendly approach. This article argues that potential SDGs should: treat stakeholders, like states, business and civil society actors, as agents on different aggregate levels of networks; incorporate good governance processes that facilitate early involvement of relevant resources, as well as equitable participation, consultative processes, and regular policy and programme implementation reviews; anchor adoption and enforcement of such rules to democratic processes in accountable organizations; and include comprehensive systems evaluations, including procedural indicators. A global framework convention for health could be a suitable instrument for handling some of the challenges related to the governance of a complex environment. It could structure and legitimize government involvement, engage stakeholders, arrange deliberation and decision-making processes with due participation and regular policy review, and define minimum standards for health services. A monitoring scheme could ensure that agents in networks comply according to whole-systems targets, locally defined outcome indicators, and process indicators, thus resolving the paradox of government control vs. local policy space. A convention could thus exploit the energy created in the encounter between civil society, international organizations and national authorities.

    The necessity for fairness and transparency during the processes of supply of consumables and capital goods within the Italian Health Service together with that of containing costs in line with budget reductions, are points outlined in the 2006 public and European Union allocation codes and related procedures. These include methods to guarantee open, limited negotiation both without or after the official announcement for competitive bidding has been made, plus mediation and framework agreement. The publicizing of announcements of bidding to potential Health Service suppliers, criteria for applicant selection and selection of personnel to comprise the panels who effectively make the choice of suppliers, are all phases that are carefully regulated at a legal level. Even small expenditures (down to 20,000) are covered by these regulations. An overview of specific responsibilities, the institution of boards of physicians and the application of sanctions ends the present review.

    2005-12-01

    Cooperation towards public goods relies on credible threats of punishment to deter cheats. However, punishing is costly, so it remains unclear who incurred the costs of enforcement in our evolutionary past. Theoretical work suggests that human cooperation may be promoted if people believe in supernatural punishment for moral transgressions. This theory is supported by new work in cognitive psychology and by anecdotal ethnographic evidence, but formal quantitative tests remain to be done. Using data from 186 societies around the globe, I test whether the likelihood of supernatural punishment-indexed by the importance of moralizing "high gods"-is associated with cooperation.

    2014-09-01

    Microbial cooperation typically consists in the sharing of secreted metabolites (referred to as public goods) within the community. Although public goods generally promote population growth, they are also vulnerable to exploitation by cheating mutants, which no longer contribute, but still benefit from the public goods produced by others. Although previous studies have identified a number of key factors that prevent the spreading of cheaters, little is known about how these factors interact and jointly shape the evolution of microbial cooperation. Here, we address this issue by investigating the interaction effects of cell diffusion, cell density, public good diffusion and durability (factors known to individually influence costs and benefits of public goods production) on selection for cooperation. To be able to quantify these effects across a wide parameter space, we developed an individual-based simulation platform, consisting of digital cooperator and cheater bacteria inhabiting a finite two-dimensional continuous toroidal surface. Our simulations, which closely mimic microbial microcolony growth, revealed that: (i) either reduced cell diffusion (which keeps cooperators together) or reduced public good diffusion (which keeps the public goods closer to the producer) is not only essential but also sufficient for cooperation to be promoted; (ii) the sign of selection for or against cooperation can change as a function of cell density and in interaction with diffusion parameters; and (iii) increased public goods durability has opposing effects on the evolution of cooperation depending on the level of cell and public good diffusion. Our work highlights that interactions between key parameters of public goods cooperation give rise to complex fitness landscapes, a finding that calls for multifactorial approaches when studying microbial cooperation in natural systems.

    Vitamin D deficiency is a major public health problem worldwide in all age groups, even in those residing in countries with low latitude, where it was generally assumed that UV radiation was adequate enough to prevent this deficiency, and in industrialized countries, where vitamin D fortification has been implemented now for years. However, most countries are still lacking data, particularly population representative data, with very limited information in infants, children, adolescents and pregnant women. Since the number of recent publications is escalating, with a broadening of the geographic diversity, the objective of the present report was to conduct a more recent systematic review of global vitamin D status, with particular emphasis in at risk groups. A systematic review was conducted in PubMed/Medline in April-June 2013 to identify articles on vitamin D status worldwide published in the last 10 years in apparently healthy individuals. Only studies with vitamin D status prevalence were included. If available, the first source selected was population-based or representative samples studies. Clinical trials, case-control studies, case reports or series, reviews, validation studies, letters, editorials, or qualitative studies were excluded. A total of 103 articles were eligible and included in the present report. Maps were created for each age group, providing an updated overview of global vitamin D status. In areas with available data, the prevalence of low vitamin D status is a global problem in all age groups, in particular in girls and women from the Middle East. These maps also evidenced the regions with missing data for each specific population groups. There is striking lack of data in infants, children and adolescents worldwide, and in most countries of South America and Africa. In conclusion, vitamin D deficiency is a global public health problem in all age groups, particularly in those from the Middle East. PMID:24239505

    The production of beneficial public goods is common in the microbial world, and so is cheating--the exploitation of public goods by nonproducing mutants. Here, we examine co-evolutionary dynamics between cooperators and cheats and ask whether cooperators can evolve strategies to reduce the burden of exploitation, and whether cheats in turn can improve their exploitation abilities. We evolved cooperators of the bacterium Pseudomonas aeruginosa, producing the shareable iron-scavenging siderophore pyoverdine, together with cheats, defective in pyoverdine production but proficient in uptake. We found that cooperators managed to co-exist with cheats in 56% of all replicates over approximately 150 generations of experimental evolution. Growth and competition assays revealed that co-existence was fostered by a combination of general adaptions to the media and specific adaptions to the co-evolving opponent. Phenotypic screening and whole-genome resequencing of evolved clones confirmed this pattern, and suggest that cooperators became less exploitable by cheats because they significantly reduced their pyoverdine investment. Cheats, meanwhile, improved exploitation efficiency through mutations blocking the costly pyoverdine-signalling pathway. Moreover, cooperators and cheats evolved reduced motility, a pattern that likely represents adaptation to laboratory conditions, but at the same time also affects social interactions by reducing strain mixing and pyoverdine sharing. Overall, we observed parallel evolution, where co-existence of cooperators and cheats was enabled by a combination of adaptations to the abiotic and social environment and their interactions.

  4. Group-Level Selection Increases Cooperation in the Public Goods Game

    When groups compete for resources, some groups will be more successful than others, forcing out less successful groups. Group-level selection is the most extreme form of group competition, where the weaker group ceases to exist, becoming extinct. We implement group-level selection in a controlled laboratory experiment in order to study its impact on human cooperation. The experiment uses variations on the standard linear public goods game. Group-level selection operates through competition for survival: the least successful, lowest-earning groups become extinct, in the sense that they no longer are able to play the game. Additional control treatments include group comparison without extinction, and extinction of the least successful individuals across groups. We find that group-level extinction produces very high contributions to the provision of the public good, while group comparison alone or individual extinction fail to cause higher contributions. Our results provide stark evidence that group-level selection enhances within-group cooperation. PMID:27574971

    Understanding the emergence of cooperation in spatial public goods game remains a grand challenge across disciplines. In most previous studies, it is assumed that the investments of all the cooperators are identical, and often equal to 1. However, it is worth mentioning that players are diverse and heterogeneous when choosing actions in the rapidly developing modern society and researchers have shown more interest to the heterogeneity of players recently. For modeling the heterogeneous players without loss of generality, it is assumed in this work that the investment of a cooperator is a random variable with uniform distribution, the mean value of which is equal to 1. The results of extensive numerical simulations convincingly indicate that heterogeneous investments can promote cooperation. Specifically, a large value of the variance of the random variable can decrease the two critical values for the result of behavioral evolution effectively. Moreover, the larger the variance is, the better the promotion effect will be. In addition, this article has discussed the impact of heterogeneous investments when the coevolution of both strategy and investment is taken into account. Comparing the promotion effect of coevolution of strategy and investment with that of strategy imitation only, we can conclude that the coevolution of strategy and investment decreases the asymptotic fraction of cooperators by weakening the heterogeneity of investments, which further demonstrates that heterogeneous investments can promote cooperation in spatial public goods game.

    Why humans cooperate in large groups and with non-kin remains a puzzle for researchers across the natural and social sciences. Investigating whether cooperation is sexually selected could contribute to an understanding of the evolution of human cooperation. Competition for access to mates could indeed select for cooperation. Using controlled laboratory experiments, we analyse whether and how the sex composition of a social environment, testosterone level, and relationship status affect contributions to a public good. The results show that variation in sex composition alters the amount of money that single men (but not men in a couple or women) contribute to a public good. Notably, in line with the competitive helping hypothesis, awareness of the presence of a woman leads to larger contributions by single men, most likely by triggering their competitiveness to be the most cooperative man in the group. However, we find no link between basal testosterone level and cooperativeness. We argue that men, notably single men, adopt cooperative behaviours as a signalling strategy in the context of mate choice and hence that cooperation is partly sexually selected. Our findings highlight the need to consider sexual selection as an additional mechanism for cooperation. PMID:27412070

  7. An evolutionary model of cooperation, fairness and altruistic punishment in public good games.

    PubMed

    2013-01-01

    We identify and explain the mechanisms that account for the emergence of fairness preferences and altruistic punishment in voluntary contribution mechanisms by combining an evolutionary perspective together with an expected utility model. We aim at filling a gap between the literature on the theory of evolution applied to cooperation and punishment, and the empirical findings from experimental economics. The approach is motivated by previous findings on other-regarding behavior, the co-evolution of culture, genes and social norms, as well as bounded rationality. Our first result reveals the emergence of two distinct evolutionary regimes that force agents to converge either to a defection state or to a state of coordination, depending on the predominant set of self- or other-regarding preferences. Our second result indicates that subjects in laboratory experiments of public goods games with punishment coordinate and punish defectors as a result of an aversion against disadvantageous inequitable outcomes. Our third finding identifies disadvantageous inequity aversion as evolutionary dominant and stable in a heterogeneous population of agents endowed initially only with purely self-regarding preferences. We validate our model using previously obtained results from three independently conducted experiments of public goods games with punishment.

  8. Resource and competitive dynamics shape the benefits of public goods cooperation in a plant pathogen.

    2012-06-01

    Cooperative benefits depend on a variety of ecological factors. Many cooperative bacteria increase the population size of their groups by making a public good available. Increased local population size can alleviate the constraints of kin competition on the evolution of cooperation by enhancing the between-group fitness of cooperators. The cooperative pathogenesis of Agrobacterium tumefaciens causes infected plants to exude opines--resources that provide a nearly exclusive source of nutrient for the pathogen. We experimentally demonstrate that opines provide cooperative A. tumefaciens cells a within-group fitness advantage over saprophytic agrobacteria. Our results are congruent with a resource-consumer competition model, which predicts that cooperative, virulent agrobacteria are at a competitive disadvantage when opines are unavailable, but have an advantage when opines are available at sufficient levels. This model also predicts that freeloading agrobacteria that catabolize opines but cannot infect plants competitively displace the cooperative pathogen from all environments. However, we show that these cooperative public goods also promote increased local population size. A model built from the Price Equation shows that this effect on group size can contribute to the persistence of cooperative pathogenesis despite inherent kin competition for the benefits of pathogenesis.

    2013-05-01

    We study the evolution of cooperation in the spatial public goods game, focusing on the effects that are brought about by the delayed distribution of goods that accumulate in groups due to the continuous investments of cooperators. We find that intermediate delays enhance network reciprocity because of a decelerated invasion of defectors, who are unable to reap the same high short-term benefits as they do in the absence of delayed distribution. Long delays, however, introduce a risk because the large accumulated wealth might fall into the wrong hands. Indeed, as soon as the curvature of a cooperative cluster turns negative, the engulfed defectors can collect the heritage of many generations of cooperators and by doing so start a waning-moon pattern that nullifies the benefits of decelerated invasion. Accidental meeting points of growing cooperative clusters may also act as triggers for the waning-moon effect, thus linking the success of cooperators with their propensity to fail in a rather bizarre way. Our results highlight that “investing in the future” is a good idea only if that future is sufficiently near and not likely to be burdened by inflation.

  12. The Water Quality in Rio Highlights the Global Public Health ...

    EPA Pesticide Factsheets

    Water quality issues in Rio have been widely publicized because of the 2016 Olympics. Recent concerns about polluted waters that athletes may be exposed to highlights the conditions that more than a billion people globally are exposed to daily. Despite these unhealthy conditions, much is unknown about the risks and exposure pathways associated with bathing in or drinking untreated or partially treated sewage. Beyond acute illness, we are learning more about the chronic sequelae that arise from repeated exposure to pathogens found in sewage. Additionally, we do not know enough about how to measure water quality, especially in developing countries. A consequence of these knowledge gaps is that data from developed countries are used to guide public health approaches in low· and middle-income settings. More data that are locally specific are needed to inform guidelines for improving sanitation and water quality in Rio and other cities in developing countries. Recent media reports of high levels of sewage contamination have caused wide-ranging concerns about the safety of sailing, rowing, and other open water events at the upcoming Olympics. This commentary discusses the global public health problem of exposures to untreated sewage and describes the need for context specific solutions to monitoring and communication and risk assessment.

  13. Competition and cooperation among different punishing strategies in the spatial public goods game

    2015-07-01

    Inspired by the fact that people have diverse propensities to punish wrongdoers, we study a spatial public goods game with defectors and different types of punishing cooperators. During the game, cooperators punish defectors with class-specific probabilities and subsequently share the associated costs of sanctioning. We show that in the presence of different punishing cooperators the highest level of public cooperation is always attainable through a selection mechanism. Interestingly, the selection does not necessarily favor the evolution of punishers who would be able to prevail on their own against the defectors, nor does it always hinder the evolution of punishers who would be unable to prevail on their own. Instead, the evolutionary success of punishing strategies depends sensitively on their invasion velocities, which in turn reveals fascinating examples of both competition and cooperation among them. Furthermore, we show that under favorable conditions, when punishment is not strictly necessary for the maintenance of public cooperation, the less aggressive, mild form of sanctioning is the sole victor of the selection process. Our work reveals that natural strategy selection cannot only promote, but sometimes also hinders competition among prosocial strategies.

  14. Role of investment heterogeneity in the cooperation on spatial public goods game.

    2014-01-01

    Public cooperation plays a significant role in the survival and maintenance of biological species, to elucidate its origin thus becomes an interesting question from various disciplines. Through long-term development, the public goods game has proven to be a useful tool, where cooperator making contribution can beat again the free-rides. Differentiating from the traditional homogeneous investment, individual trend of making contribution is more likely affected by the investment level of his neighborhood. Based on this fact, we here investigate the impact of heterogeneous investment on public cooperation, where the investment sum is mapped to the proportion of cooperators determined by parameter α. Interestingly, we find, irrespective of interaction networks, that the increment of α (increment of heterogeneous investment) is beneficial for promoting cooperation and even guarantees the complete cooperation dominance under weak replication factor. While this promotion effect can be attributed to the formation of more robust cooperator clusters and shortening END period. Moreover, we find that this simple mechanism can change the potential interaction network, which results in the change of phase diagrams. We hope that our work may shed light on the understanding of the cooperative behavior in other social dilemmas.

  15. The Imperative of Public Health Education: A Global Perspective.

    PubMed

    White, Franklin

    2013-01-01

    This review positions public health as an endeavour that requires a high order of professionalism in addressing the health of populations; this requires investment in an educational capacity that is designed to meet this need. In the global context, the field has evolved enormously over the past half century, supported by institutions such as the World Bank, the World Health Organization and the Institute of Medicine. Operational structures are formulated by strategic principles, with educational and career pathways guided by competency frameworks, all requiring modulation according to local, national and global realities. Talented and well-motivated individuals are attracted by its multidisciplinary and transdisciplinary environment, and the opportunity to achieve interventions that make real differences to people's lives. The field is globally competitive and open to many professional backgrounds based on merit. Its competencies correspond with assessments of population needs, and the ways in which strategies and services are formulated. Thus, its educational planning is needs-based and evidence-driven. This review explores four public health education levels: graduate, undergraduate, continuing professional education and promotion of health literacy for general populations. The emergence of accreditation schemes is examined, focusing on their relative merits and legitimate international variations. The role of relevant research policies is recognized, along with the need to foster professional and institutional networks in all regions of the world. It is critically important for the health of populations that nations assess their public health human resource needs and develop their ability to deliver this capacity, and not depend on other countries to supply it.

  16. Global Warming and Energy Transition: A Public Policy Imperative

    2006-12-01

    The historic transition from fossil fuels to alternative energy resources has begun. This development is commonly attributed to increasing energy costs and the need for energy security. Looming ever larger, however, is the issue that will soon drive the third energy revolution: global warming. A preponderance of evidence documents accelerating warming, enlarging impacts, and human causes -- principally combustion of fossil fuels. The carbon dioxide (C02) content of Earth's atmosphere has increased more than 35 percent since the beginning of the industrial revolution and is the highest in 650,000 years. This dramatic rise of C02 and attendant positive feedbacks are already forcing significant impacts worldwide. These include atmospheric warming with shifting climatic and habitat zones, spreading tropical disease, and more extreme weather events; rapid ice loss at high latitude and high altitude; ocean warming and acidification with coral reef bleaching and intensifying tropical storms; rising sea level; and accelerating extinction rates. The 2007 draft report of the Intergovernmental Panel on Climate Change (IPCC) predicts greater warming than in previous models. A tipping point to abrupt climate change may be imminent. It is incumbent upon geoscientists and geoscience educators to assume leadership in addressing this challenge through public outreach and general education. The following topics should be integrated into all appropriate courses: the evidence of global warming and its causes; observed present and predicted future impacts of global warming; mitigation and adaptation strategies; and implications for energy policies and economic opportunities. New entry-level science and general education courses -- such as Climate Change Fundamentals and Energy in Nature, Technology, and Society -- are proving to be effective should be widely developed In addition, by workshops and presentations to civic and business organizations and by demonstrated examples of

  17. Public goods and private interests: The role of voluntary green power demand in achieving environmental improvements

    NASA Astrophysics Data System (ADS)

    Wiser, Ryan Hayes

    This dissertation explores the role of consumer purchasing behavior in providing public, environmental goods. It does so by empirically evaluating one market---voluntary demand for renewable energy. The dissertation addresses the following five research questions: (1) What does early experience with green power marketing tell us about the prospects for this market to deliver environmental benefits? (2) What product design and marketing approaches might be used to increase voluntary demand? (3) What motivates non-residential customers to voluntarily purchase green power? (4) What role might public policy play in the creation of the green power market? (5) What preferences do individuals hold on the most appropriate forms of support for renewable energy? By helping to answer these questions, this dissertation seeks to better understand the gap between widespread positive attitudes for the environment and an often-anemic response to green product offerings. It contributes to not only the public goods and environmental marketing literatures, but also to contingent valuation methodology and to an emerging literature on the motivations of firms to contribute to environmental causes. The analysis performed is diverse, and includes: a literature review, a mail survey of green power marketers, a mail survey of non-residential green power customers, and contingent valuation and opinion surveys of U.S. residents. Detailed statistical analysis is performed on the data collected from the residential and non-residential surveys. The analysis reveals that customer participation in green power programs to date has been weak. The possibility that the traditional economic concept of "free riding" may explain this low response is raised, and the dissertation identifies a number of marketing approaches that might be used to partially combat this problem. Analysis of survey data shows that non-residential green power purchases have been motivated principally by altruistic concerns

    Spatial evolutionary games have mainly been studied on a single, isolated network. However, in real world systems, many interaction topologies are not isolated but many different types of networks are inter-connected to each other. In this study, we investigate the spatial evolutionary public goods game (SEPGG) on double-layered random networks (DRN). Based on the mean-field type arguments and numerical simulations, we find that SEPGG on DRN shows very rich interesting phenomena, especially, depending on the size of each layer, intra-connectivity, and inter-connected couplings, the network reciprocity of SEPGG on DRN can be drastically enhanced through the inter-connected coupling. Furthermore, SEPGG on DRN can provide a more general framework which includes the evolutionary dynamics on multiplex networks and inter-connected networks at the same time. PMID:27503801

    The evolution of cooperation among nonrelated individuals is one of the fundamental problems in biology and social sciences. Reciprocal altruism fails to provide a solution if interactions are not repeated often enough or groups are too large. Punishment and reward can be very effective but require that defectors can be traced and identified. Here we present a simple but effective mechanism operating under full anonymity. Optional participation can foil exploiters and overcome the social dilemma. In voluntary public goods interactions, cooperators and defectors will coexist. We show that this result holds under very diverse assumptions on population structure and adaptation mechanisms, leading usually not to an equilibrium but to an unending cycle of adjustments (a Red Queen type of evolution). Thus, voluntary participation offers an escape hatch out of some social traps. Cooperation can subsist in sizable groups even if interactions are not repeated, defectors remain anonymous, players have no memory, and assortment is purely random.

    2011-10-01

    We have studied the evolution of strategies in spatial public goods games where both individual (peer) and institutional (pool) punishments are present in addition to unconditional defector and cooperator strategies. The evolution of strategy distribution is governed by imitation based on the random sequential comparison of neighbors’ payoff for a fixed level of noise. Using numerical simulations, we evaluate the strategy frequencies and phase diagrams when varying the synergy factor, punishment cost, and fine. Our attention is focused on two extreme cases describing all the relevant behaviors in such a complex system. According to our numerical data peer punishers prevail and control the system behavior in a large segments of parameters while pool punishers can only survive in the limit of weak peer punishment when a rich variety of solutions is observed. Paradoxically, the two types of punishment may extinguish each other’s impact, resulting in the triumph of defectors. The technical difficulties and suggested methods are briefly discussed.

  1. Defector-accelerated cooperativeness and punishment in public goods games with mutations

    2010-05-01

    We study the evolution of cooperation in spatial public goods games with four competing strategies: cooperators, defectors, punishing cooperators, and punishing defectors. To explore the robustness of the cooperation-promoting effect of costly punishment, besides the usual strategy adoption dynamics we also apply strategy mutations. As expected, frequent mutations create kind of well-mixed conditions, which support the spreading of defectors. However, when the mutation rate is small, the final stationary state does not significantly differ from the state of the mutation-free model, independently of the values of the punishment fine and cost. Nevertheless, the mutation rate affects the relaxation dynamics. Rare mutations can largely accelerate the spreading of costly punishment. This is due to the fact that the presence of defectors breaks the balance of power between both cooperative strategies, which leads to a different kind of dynamics.

    2010-12-01

    We study the evolution of cooperation in spatial public goods games, whereby a coevolutionary rule is introduced that aims to integrate group penalty into the framework of evolutionary games. Existing groups are deleted whenever the collective gains of the focal individuals are less than a deletion threshold value. Meanwhile, newcomers are added after each game iteration to maintain the fixed population size. The networking effect is also studied via four representative interaction networks which are associated with the population structure. We conclude that the cooperation level has a strong dependence on the deletion threshold, and the suitable value range of the deletion threshold which is associated with the maximal cooperation frequency has been found. Simulation results also show that optimum values of the deletion threshold can still warrant the most potent promotion of cooperation, irrespective of which of the four topologies is applied.

    Inspired by the fact that opportunities in reality are heterogeneous for individuals due to social selection, we propose an evolutionary public goods game model considering the social selection of game organizers occurring on a square lattice. We introduce a simple rule that, depending on the value of a single parameter μ, influences the selection of players that are considered as potential game organizers. For positive μ players with a high payoff will be considered more likely. Setting μ equal to zero returns the random selection of game organizers. We find that increasing the probability of selecting the wealthier individuals as game organizers can effectively promote cooperation. We show that the promotion of cooperation attributes to the dominance of the clusters of cooperative organizers in the population by investigating the evolution of spatial patterns.

  4. Prosocial preferences do not explain human cooperation in public-goods games.

    Burton-Chellew, Maxwell N; West, Stuart A

    2013-01-02

    It has become an accepted paradigm that humans have "prosocial preferences" that lead to higher levels of cooperation than those that would maximize their personal financial gain. However, the existence of prosocial preferences has been inferred post hoc from the results of economic games, rather than with direct experimental tests. Here, we test how behavior in a public-goods game is influenced by knowledge of the consequences of actions for other players. We found that (i) individuals cooperate at similar levels, even when they are not informed that their behavior benefits others; (ii) an increased awareness of how cooperation benefits others leads to a reduction, rather than an increase, in the level of cooperation; and (iii) cooperation can be either lower or higher than expected, depending on experimental design. Overall, these results contradict the suggested role of the prosocial preferences hypothesis and show how the complexity of human behavior can lead to misleading conclusions from controlled laboratory experiments.

    Existing theory, empirical, clinical and field research all predict that reducing the virulence of individuals within a pathogen population will reduce the overall virulence, rendering disease less severe. Here, we show that this seemingly successful disease management strategy can fail with devastating consequences for infected hosts. We deploy cooperation theory and a novel synthetic system involving the rice blast fungus Magnaporthe oryzae. In vivo infections of rice demonstrate that M. oryzae virulence is enhanced, quite paradoxically, when a public good mutant is present in a population of high-virulence pathogens. We reason that during infection, the fungus engages in multiple cooperative acts to exploit host resources. We establish a multi-trait cooperation model which suggests that the observed failure of the virulence reduction strategy is caused by the interference between different social traits. Multi-trait cooperative interactions are widespread, so we caution against the indiscriminant application of anti-virulence therapy as a disease-management strategy.

    2010-06-01

    We propose a mechanism allowing strategy diversity instead of a common combination of cooperation and defection to study how cooperation evolves in public goods games. Each individual is assigned a variable valued in the unit interval as its cooperation degree. Thus, diverse cooperation degrees express the diversity of game strategies in the way of multiple contributions of players, and the investment in the common pool is positively correlated with cooperation degrees correspondingly. Moreover, we also define two particular roles named altruist and egotist defined locally since they depend on the behavior of their neighboring players. Numerical simulations show that the proposed diversity of strategies can substantially evoke the emergence and maintenance of cooperation. Notably, we also find that no player will act as a long-term exploiter (egotist) or exploitee (altruist) in the whole evolutionary process.

    Objective To provide a legal and ethical analysis of some of the implementation challenges faced by the Population Therapeutics Research Group (PTRG) at Memorial University (Canada), in using genealogical information offered by individuals for its genetics research database. Materials and methods This paper describes the unique historical and genetic characteristics of the Newfoundland and Labrador founder population, which gave rise to the opportunity for PTRG to build the Newfoundland Genealogy Database containing digitized records of all pre-confederation (1949) census records of the Newfoundland founder population. In addition to building the database, PTRG has developed the Heritability Analytics Infrastructure, a data management structure that stores genotype, phenotype, and pedigree information in a single database, and custom linkage software (KINNECT) to perform pedigree linkages on the genealogy database. Discussion A newly adopted legal regimen in Newfoundland and Labrador is discussed. It incorporates health privacy legislation with a unique research ethics statute governing the composition and activities of research ethics boards and, for the first time in Canada, elevating the status of national research ethics guidelines into law. The discussion looks at this integration of legal and ethical principles which provides a flexible and seamless framework for balancing the privacy rights and welfare interests of individuals, families, and larger societies in the creation and use of research data infrastructures as public goods. Conclusion The complementary legal and ethical frameworks that now coexist in Newfoundland and Labrador provide the legislative authority, ethical legitimacy, and practical flexibility needed to find a workable balance between privacy interests and public goods. Such an approach may also be instructive for other jurisdictions as they seek to construct and use biobanks and related research platforms for genetic research. PMID

  8. Coordination between veterinary services and other relevant authorities: a key component of good public governance.

    PubMed

    Bellemain, V

    2012-08-01

    Coordination between Veterinary Services and other relevant authorities is a key component of good public governance, especially for effective action and optimal management of available resources. The importance of good coordination is reflected in the World Organisation for Animal Health'Tool forthe Evaluation of Performance of Veterinary Services', which includes a critical competency on coordination. Many partners from technical, administrative and legal fields are involved. The degree of formalisation of coordination tends to depend on a country's level of organisation and development. Contingency plans against avian influenza led to breakthroughs in many countries in the mid-2000s. While interpersonal relationships remain vital, not everything should hinge on them. Organisation and management are critical to operational efficiency. The distribution of responsibilities needs to be defined clearly, avoiding duplication and areas of conflict. Lead authorities should be designated according to subject (Veterinary Services in animal health areas) and endowed with the necessary legitimacy. Lead authorities will be responsible for coordinating the drafting and updating of the relevant documents: agreements between authorities, contingency plans, standard operating procedures, etc.

    2015-01-01

    In the Royal Academy of Sciences of Paris (founded 1666), expressions of a masculine culture of science echoed contemporary language used to articulate the aristocracy's value to crown and state--even though the academy was not an aristocratic institution as such. In the eighteenth century, the pursuit of science became a new form of manly service to the crown, often described in terms of useful knowledge and benefit to the public good [le bien public]. This article explores the connection of academic scientific knowledge to the domestic spaces where it was made and, in particular, to the household of R.-A. Ferchault de Réaumur, an exemplary academician. Although Réaumur had neither wife nor children, a complex net of affective ties, some of them familial, linked the members of the household, which accommodated women (the artist Hélène Dumoustier and her female relatives) as well as men (a series of assistants, many of whom eventually entered the academy). As head of this dynamic household, Réaumur produced not only scientific results but also future academicians.

  10. Good governance of animal health systems and public-private partnerships: an Australian case study.

    Black, P F

    2012-08-01

    The animal health system in Australia has evolved over more than 100 years and includes innovative public-private partnership arrangements. The establishment in 1996 of Animal Health Australia (AHA), a not-for-profit company, was a crucial development which formalised arrangements for shared decision-making and funding across both government and industry stakeholders. However, Federal and State governments retain legislative authority for animal health control. Accordingly, all programmes must recognise that the public sector remains an executive arm of government, accountable for its actions. Hence, much effort has been invested in ensuring that the governance arrangements within AHA are lawful and transparent. The Emergency Animal Disease Response Agreement (EADRA) is a very good example of governance arrangements that are sustainably financed, widely available, provided efficiently, without waste or duplication, and in a manner that is transparent and free of fraud or corruption. The benefits of EADRA include certainty and greater transparency of funding; greater efficiency through increased probability of a rapid response to an occurrence of any of 65 diseases; and industry participation in the management and financing of such a response.

    A voluntary blood donation system can be seen as a public good. People can take advantage without contributing and have a free ride. We empirically analyse the extent of free riding and its determinants. Interviews of the general public in Spain (n = 1,211) were used to ask whether respondents were (or have been) regular blood donors and, if not, the reason. Free riders are defined as those who are medically capable to donate blood but do not. In addition, we distinguish four different types of free riding depending on the reason given for not donating. Binomial and multinomial logit models estimate the effect of individual characteristics on the propensity to free ride and the likelihood of the free rider types. Amongst those who are able to donate, there is a 67 % probability of being a free rider. The most likely free rider is female, single, with low/no education and abstained from voting in a recent national election. Gender, age, religious practice, political participation and regional income explain the type of free rider.

    OBJECTIVE: In December 2001, an expert consultation convened by WHO identified strengthening national and global chemical incident preparedness and response as a priority. WHO is working towards this objective by developing a surveillance and response system for chemical incidents. This report describes the frequency, nature and geographical location of acute chemical incidents of potential international concern from August 2002 to December 2003. METHODS: Acute chemical incidents were actively identified through several informal (e.g. Internet-based resources) and formal (e.g. various networks of organizations) sources and assessed against criteria for public health emergencies of international concern using the then proposed revised International Health Regulations (IHR). WHO regional and country offices were contacted to obtain additional information regarding identified incidents. FINDINGS: Altogether, 35 chemical incidents from 26 countries met one or more of the IHR criteria. The WHO European Region accounted for 43% (15/35) of reports. The WHO Regions for Africa, Eastern Mediterranean and Western Pacific each accounted for 14% (5/35); South-East Asia and the Americas accounted for 9% (3/35) and 6% (2/35), respectively. Twenty-three (66%) events were identified within 24 hours of their occurrence. CONCLUSION: To our knowledge this is the first global surveillance system for chemical incidents of potential international concern. Limitations such as geographical and language bias associated with the current system are being addressed. Nevertheless, the system has shown that it can provide early detection of important events, as well as information on the magnitude and geographical distribution of such incidents. It can therefore contribute to improving global public health preparedness. PMID:16462985

  13. Pharmacogenomic technologies: a necessary "luxury" for better global public health?

    2011-01-01

    Background Pharmacogenomic technologies aim to redirect drug development to increase safety and efficacy of individual care. There is much hope that their implementation in the drug development process will help respond to population health needs, particularly in developing countries. However, there is also fear that novel pharmacogenomic drugs will remain too costly, be designed for the needs of the wealthy nations, and so constitute an unnecessary "luxury" for most populations. In this paper, we analyse the promise that pharmacogenomic technologies hold for improving global public health and identify strategies and challenges associated with their implementation. Discussion This paper evaluates the capacity of pharmacogenomic technologies to meet six criteria described by the University of Toronto Joint Centre for Bioethics group: 1) impact of the technology, 2) technology appropriateness, 3) capacity to address local burdens, 4) feasibility to be implemented in reasonable time, 5) capacity to reduce the knowledge gap, and 6) capacity for indirect benefits. We argue that the implementation of pharmacogenomic technologies in the drug development process can positively impact population health. However, this positive impact depends on how and for which purposes the technologies are used. We discuss the potential of these technologies to stimulate drug discovery in the case of rare (orphan diseases) or neglected diseases, but also to reduce acute adverse drug reactions in infectious disease treatment and prevention, which promises to improve global public health. Conclusions The implementation of pharmacogenomic technologies may lead to the development of drugs that appear to be a "luxury" for populations in need of numerous interventions that are known to have a demonstrable impact on population health (e.g., secure access to potable water, reduction of social inequities, health education). However, our analysis shows that pharmacogenomic technologies do have the

  17. Global trade, public health, and health services: stakeholders' constructions of the key issues.

    2005-09-01

    Focusing mainly on the United States and Latin America, we aimed to identify the constructions of social reality held by the major stakeholders participating in policy debates about global trade, public health, and health services. In a multi-method, qualitative design, we used three sources of data: research and archival literature, 1980-2004; interviews with key informants who represented major organizations participating in these debates, 2002-2004; and organizational reports, 1980-2004. We targeted several types of organizations: government agencies, international financial institutions (IFIs) and trade organizations, international health organizations, multinational corporations, and advocacy groups. Many governments in Latin America define health as a right and health services as a public good. Thus, the government bears responsibility for that right. In contrast, the US government's philosophy of free trade and promoting a market economy assumes that by expanding the private sector, improved economic conditions will improve overall health with a minimum government provision of health care. US government agencies also view promotion of global health as a means to serve US interests. IFIs have emphasized reforms that include reduction and privatization of public sector services. International health organizations have tended to adopt the policy perspectives of IFIs and trade organizations. Advocacy groups have emphasized the deleterious effects of international trade agreements on public health and health services. Organizational stakeholders hold widely divergent constructions of reality regarding trade, public health, and health services. Social constructions concerning trade and health reflect broad ideologies concerning the impacts of market processes. Such constructions manifest features of "creed," regarding the role of the market in advancing human purposes and meeting human needs. Differences in constructions of trade and health constrain policies to

  19. Harbouring public good mutants within a pathogen population can increase both fitness and virulence

    2016-01-01

    Existing theory, empirical, clinical and field research all predict that reducing the virulence of individuals within a pathogen population will reduce the overall virulence, rendering disease less severe. Here, we show that this seemingly successful disease management strategy can fail with devastating consequences for infected hosts. We deploy cooperation theory and a novel synthetic system involving the rice blast fungus Magnaporthe oryzae. In vivo infections of rice demonstrate that M. oryzae virulence is enhanced, quite paradoxically, when a public good mutant is present in a population of high-virulence pathogens. We reason that during infection, the fungus engages in multiple cooperative acts to exploit host resources. We establish a multi-trait cooperation model which suggests that the observed failure of the virulence reduction strategy is caused by the interference between different social traits. Multi-trait cooperative interactions are widespread, so we caution against the indiscriminant application of anti-virulence therapy as a disease-management strategy.

  20. The evolution of anti-social rewarding and its countermeasures in public goods games

    2015-01-01

    Cooperation in joint enterprises can easily break down when self-interests are in conflict with collective benefits, causing a tragedy of the commons. In such social dilemmas, the possibility for contributors to invest in a common pool-rewards fund, which will be shared exclusively among contributors, can be powerful for averting the tragedy, as long as the second-order dilemma (i.e. withdrawing contribution to reward funds) can be overcome (e.g. with second-order sanctions). However, the present paper reveals the vulnerability of such pool-rewarding mechanisms to the presence of reward funds raised by defectors and shared among them (i.e. anti-social rewarding), as it causes a cooperation breakdown, even when second-order sanctions are possible. I demonstrate that escaping this social trap requires the additional condition that coalitions of defectors fare poorly compared with pro-socials, with either (i) better rewarding abilities for the latter or (ii) reward funds that are contingent upon the public good produced beforehand, allowing groups of contributors to invest more in reward funds than groups of defectors. These results suggest that the establishment of cooperation through a collective positive incentive mechanism is highly vulnerable to anti-social rewarding and requires additional countermeasures to act in combination with second-order sanctions.

    It is often the case that rational individuals will adjust their connectivity in commercial or social activities for maximizing their payoffs. In this process, we can observe that individuals always gather around a leader or a competitive individual who can bring them more benefits. Inspired by this, we propose a strategy that impels nodes of network to connect with a specific node that we have specified with the perspective of spatial evolutionary public goods game. Thus a node is specified and given a larger enhancement factor which reflects his advantage over others. Then we employ a payoff-oriented preferential rewire strategy that individual will sever a neighbor who provides him with the lowest benefit and then link others randomly. The results illustrate that this strategy not only ensures the promotion of cooperation but also increases the degree of the specified node. Furthermore, we analyze the effect of two relevant parameters: enhancement factor and rewire frequency. We find that if the control strategy expects to work effectively, these two parameters have to ensure an evolution environment where cooperators can prevail defectors. We also conclude that a relatively low rewire frequency contributes to increasing the degree of the specified node. Meanwhile we attempt to present our interpretations for these phenomena.

  2. Individual wealth-based selection supports cooperation in spatial public goods games.

    PubMed

    Chen, Xiaojie; Szolnoki, Attila

    2016-09-06

    In a social dilemma game group members are allowed to decide if they contribute to the joint venture or not. As a consequence, defectors, who do not invest but only enjoy the mutual benefit, prevail and the system evolves onto the tragedy of the common state. This unfortunate scenario can be avoided if participation is not obligatory but only happens with a given probability. But what if we also consider a player's individual wealth when to decide about participation? To address this issue we propose a model in which the probabilistic participation in the public goods game is combined with a conditional investment mode that is based on individual wealth: if a player's wealth exceeds a threshold value then it is qualified and can participate in the joint venture. Otherwise, the participation is forbidden in the investment interactions. We show that if only probabilistic participation is considered, spatially structured populations cannot support cooperation better than well-mixed populations where full defection state can also be avoided for small participation probabilities. By adding the wealth-based criterion of participation, however, structured populations are capable to augment network reciprocity relevantly and allow cooperator strategy to dominate in a broader parameter interval.

  3. Cooperation and Contagion in Web-Based, Networked Public Goods Experiments

    2011-01-01

    A longstanding idea in the literature on human cooperation is that cooperation should be reinforced when conditional cooperators are more likely to interact. In the context of social networks, this idea implies that cooperation should fare better in highly clustered networks such as cliques than in networks with low clustering such as random networks. To test this hypothesis, we conducted a series of web-based experiments, in which 24 individuals played a local public goods game arranged on one of five network topologies that varied between disconnected cliques and a random regular graph. In contrast with previous theoretical work, we found that network topology had no significant effect on average contributions. This result implies either that individuals are not conditional cooperators, or else that cooperation does not benefit from positive reinforcement between connected neighbors. We then tested both of these possibilities in two subsequent series of experiments in which artificial seed players were introduced, making either full or zero contributions. First, we found that although players did generally behave like conditional cooperators, they were as likely to decrease their contributions in response to low contributing neighbors as they were to increase their contributions in response to high contributing neighbors. Second, we found that positive effects of cooperation were contagious only to direct neighbors in the network. In total we report on 113 human subjects experiments, highlighting the speed, flexibility, and cost-effectiveness of web-based experiments over those conducted in physical labs. PMID:21412431

  4. The dynamics of human behavior in the public goods game with institutional incentives

    2016-01-01

    The empirical research on the public goods game (PGG) indicates that both institutional rewards and institutional punishment can curb free-riding and that the punishment effect is stronger than the reward effect. Self-regarding models that are based on Nash equilibrium (NE) strategies or evolutionary game dynamics correctly predict which incentives are best at promoting cooperation, but individuals do not play these rational strategies overall. The goal of our study is to investigate the dynamics of human decision making in the repeated PGG with institutional incentives. We consider that an individual’s contribution is affected by four factors, which are self-interest, the behavior of others, the reaction to rewards, and the reaction to punishment. We find that people on average do not react to rewards and punishment, and that self-interest and the behavior of others sufficiently explain the dynamics of human behavior. Further analysis suggests that institutional incentives promote cooperation by affecting the self-regarding preference and that the other-regarding preference seems to be independent of incentive schemes. Because individuals do not change their behavioral patterns even if they were not rewarded or punished, the mere potential to punish defectors and reward cooperators can lead to considerable increases in the level of cooperation.

    We study the spatial evolutionary public goods game (SEPGG) with voluntary or optional participation on a complete graph (CG) and on dense networks. Based on analyses of the SEPGG rate equation on finite CG, we find that SEPGG has two stable states depending on the value of multiplication factor r, illustrating how the ``tragedy of the commons'' and ``an anomalous state without any active participants'' occurs in real-life situations. When r is low (), the state with only loners is stable, and the state with only defectors is stable when r is high (). We also derive the exact scaling relation for r*. All of the results are confirmed by numerical simulation. Furthermore, we find that a cooperator-dominant state emerges when the number of participants or the mean degree, , decreases. We also investigate the scaling dependence of the emergence of cooperation on r and . These results show how ``tragedy of the commons'' disappears when cooperation between egoistic individuals without any additional socioeconomic punishment increases.

    We study the evolution of cooperation in spatial public goods games where, besides the classical strategies of cooperation (C) and defection (D), we consider punishing cooperators (PC) or punishing defectors (PD) as an additional strategy. Using a minimalist modeling approach, our goal is to separately clarify and identify the consequences of the two punishing strategies. Since punishment is costly, punishing strategies lose the evolutionary competition in case of well-mixed interactions. When spatial interactions are taken into account, however, the outcome can be strikingly different, and cooperation may spread. The underlying mechanism depends on the character of the punishment strategy. In the case of cooperating punishers, increasing the fine results in a rising cooperation level. In contrast, in the presence of the PD strategy, the phase diagram exhibits a reentrant transition as the fine is increased. Accordingly, the level of cooperation shows a non-monotonous dependence on the fine. Remarkably, punishing strategies can spread in both cases, but based on largely different mechanisms, which depend on the cooperativeness (or not) of punishers.

    2016-01-01

    We present a new spatial public goods game model, which takes the individual reputation and behavior diversity into account at the same time, to investigate the evolution of cooperation. Initially, each player x will be endowed with an integer Rx between 1 and Rmax to characterize his reputation value, which will be adaptively varied according to the strategy action at each time step. Then, the agents play the game and the system proceeds in accordance with a Fermi-like rule, in which a multiplicative factor (wy) to denote the individual difference to perform the strategy transfer will be placed before the traditional Fermi probability. For influential participants, wy is set to be 1.0, but be a smaller value w (0 < w < 1) for non-influential ones. Large quantities of simulations demonstrate that the cooperation behavior will be obviously influenced by the reputation threshold (RC), and the greater the threshold, the higher the fraction of cooperators. The origin of promotion of cooperation will be attributed to the fact that the larger reputation threshold renders the higher heterogeneity in the fraction of two types of players and strategy spreading capability. Our work is conducive to a better understanding of the emergence of cooperation within many real-world systems.

    Public goods games (PGGs) represent one of the most useful tools to study group interactions. However, even if they could provide an explanation for the emergence and stability of cooperation in modern societies, they are not able to reproduce some key features observed in social and economical interactions. The typical shape of wealth distribution—known as Pareto Law—and the microscopic organization of wealth production are two of them. Here, we introduce a modification to the classical formulation of PGGs that allows for the emergence of both of these features from first principles. Unlike traditional PGGs, where players contribute equally to all the games in which they participate, we allow individuals to redistribute their contribution according to what they earned in previous rounds. Results from numerical simulations show that not only a Pareto distribution for the pay-offs naturally emerges but also that if players do not invest enough in one round they can act as defectors even if they are formally cooperators. Our results not only give an explanation for wealth heterogeneity observed in real data but also point to a conceptual change on cooperation in collective dilemmas.

    Social dilemmas are characterized by conflicts between immediate self-interest and long-term collective goals. Although such conflicts lie at the heart of various challenging social interactions, we know little about how cooperation in these situations develops. To extend work on social dilemmas to child and adolescent samples, we developed an age-appropriate computer task (the Pizzagame) with the structural features of a public goods game (PGG). We administered the Pizzagame to a sample of 191 children 9 to 16 years of age. Subjects were led to believe they were playing the game over the Internet with three sets of two same-aged, same-sex co-players. In fact, the co-players were computer-generated and programmed to expose children to three consecutive conditions: (1) a cooperative strategy, (2) a selfish strategy, and (3) divergent cooperative-selfish strategies. Supporting the validity of the Pizzagame, our results revealed that children and adolescents displayed conditional cooperation, such that their contributions rose with the increasing cooperativeness of their co-players. Age and gender did not influence children and adolescents' cooperative behavior within each condition. However, older children adapted their behavior more flexibly between conditions to parallel the strategies of their co-players. These results support the utility of the Pizzagame as a feasible, reliable, and valid instrument for assessing and quantifying child and adolescent cooperative behavior. Moreover, these findings extend previous work showing that age influences cooperative behavior in the PGG.

    We investigate the spatial Public Goods Game in the presence of fitness-driven and conformity-driven agents. This framework usually considers only the former type of agents, i.e., agents that tend to imitate the strategy of their fittest neighbors. However, whenever we study social systems, the evolution of a population might be affected also by social behaviors as conformism, stubbornness, altruism, and selfishness. Although the term evolution can assume different meanings depending on the considered domain, here it corresponds to the set of processes that lead a system towards an equilibrium or a steady state. We map fitness to the agents' payoff so that richer agents are those most imitated by fitness-driven agents, while conformity-driven agents tend to imitate the strategy assumed by the majority of their neighbors. Numerical simulations aim to identify the nature of the transition, on varying the amount of the relative density of conformity-driven agents in the population, and to study the nature of related equilibria. Remarkably, we find that conformism generally fosters ordered cooperative phases and may also lead to bistable behaviors.

    The extensive intratumor heterogeneity revealed by sequencing cancer genomes is an essential determinant of tumor progression, diagnosis, and treatment. What maintains heterogeneity remains an open question because competition within a tumor leads to a strong selection for the fittest subclone. Cancer cells also cooperate by sharing molecules with paracrine effects, such as growth factors, and heterogeneity can be maintained if subclones depend on each other for survival. Without strict interdependence between subclones, however, nonproducer cells can free-ride on the growth factors produced by neighboring producer cells, a collective action problem known in game theory as the "tragedy of the commons," which has been observed in microbial cell populations. Here, we report that similar dynamics occur in cancer cell populations. Neuroendocrine pancreatic cancer (insulinoma) cells that do not produce insulin-like growth factor II (IGF-II) grow slowly in pure cultures but have a proliferation advantage in mixed cultures, where they can use the IGF-II provided by producer cells. We show that, as predicted by evolutionary game theory, producer cells do not go extinct because IGF-II acts as a nonlinear public good, creating negative frequency-dependent selection that leads to a stable coexistence of the two cell types. Intratumor cell heterogeneity can therefore be maintained even without strict interdependence between cell subclones. Reducing the amount of growth factors available within a tumor may lead to a reduction in growth followed by a new equilibrium, which may explain relapse in therapies that target growth factors.

    Decisions to cooperate are often delegated to a third party. We examined whether cooperation differs when decisions are made for a third party compared with ourselves and specified which motives are important for third-party cooperation. Participants played multiple rounds of a public goods game (PGG). In Study 1, we varied personal involvement from high to low; participants played for themselves (Self), for themselves and a third party (Shared), and solely for a third party (Third Party). Participants contributed most when personal involvement was lowest (i.e., Third Party) and least when personal involvement was high (i.e., Self). Study 2 explored if social motives underlie third-party cooperation by comparing cooperation with social (human) and non-social (computer) group members. Reducing personal involvement in the PGG (i.e., Third Party) increased cooperation in social contexts compared with non-social contexts, indicating enhanced collective interest. Increased cooperation for a third party may result from taking the other's perspective, thereby increasing social norm preferences.

    A unique feature of adolescent social re-orientation is heightened sensitivity to peer influence when taking risks. However, positive peer influence effects are not yet well understood. The present fMRI study tested a novel hypothesis, by examining neural correlates of prosocial peer influence on donation decisions in adolescence. Participants (age 12-16 years; N = 61) made decisions in anonymous groups about the allocation of tokens between themselves and the group in a public goods game. Two spectator groups of same-age peers-in fact youth actors-were allegedly online during some of the decisions. The task had a within-subjects design with three conditions: (1) EVALUATION: spectators evaluated decisions with likes for large donations to the group, (2) Spectator: spectators were present but no evaluative feedback was displayed and (3) Alone: no spectators nor feedback. Results showed that prosocial behavior increased in the presence of peers, and even more when participants received evaluative feedback from peers. Peer presence resulted in enhanced activity in several social brain regions including medial prefrontal cortex, temporal parietal junction (TPJ), precuneus and superior temporal sulcus. TPJ activity correlated with donations, which suggests similar networks for prosocial behavior and sensitivity to peers. These findings highlight the importance of peers in fostering prosocial development throughout adolescence.

    Punishment is a popular tool when governing commons in situations where free riders would otherwise take over. It is well known that sanctioning systems, such as the police and courts, are costly and thus can suffer from those who free ride on other's efforts to maintain the sanctioning systems (second-order free riders). Previous game-theory studies showed that if populations are very large, pool punishment rarely emerges in public good games, even when participation is optional, because of second-order free riders. Here we show that a matching fund for rewarding cooperation leads to the emergence of pool punishment, despite the presence of second-order free riders. We demonstrate that reward funds can pave the way for a transition from a population of free riders to a population of pool punishers. A key factor in promoting the transition is also to reward those who contribute to pool punishment, yet not abstaining from participation. Reward funds eventually vanish in raising pool punishment, which is sustainable by punishing the second-order free riders. This suggests that considering the interdependence of reward and punishment may help to better understand the origins and transitions of social norms and institutions.

    The results of numerous economic games suggest that humans behave more cooperatively than would be expected if they were maximizing selfish interests. It has been argued that this is because individuals gain satisfaction from the success of others, and that such prosocial preferences require a novel evolutionary explanation. However, in previous games, imperfect behavior would automatically lead to an increase in cooperation, making it impossible to decouple any form of mistake or error from prosocial cooperative decisions. Here we empirically test between these alternatives by decoupling imperfect behavior from prosocial preferences in modified versions of the public goods game, in which individuals would maximize their selfish gain by completely (100%) cooperating. We found that, although this led to higher levels of cooperation, it did not lead to full cooperation, and individuals still perceived their group mates as competitors. This is inconsistent with either selfish or prosocial preferences, suggesting that the most parsimonious explanation is imperfect behavior triggered by psychological drives that can prevent both complete defection and complete cooperation. More generally, our results illustrate the caution that must be exercised when interpreting the evolutionary implications of economic experiments, especially the absolute level of cooperation in a particular treatment.

  19. Evolution of All-or-None Strategies in Repeated Public Goods Dilemmas

    PubMed Central

    2014-01-01

    Many problems of cooperation involve repeated interactions among the same groups of individuals. When collective action is at stake, groups often engage in Public Goods Games (PGG), where individuals contribute (or not) to a common pool, subsequently sharing the resources. Such scenarios of repeated group interactions materialize situations in which direct reciprocation to groups may be at work. Here we study direct group reciprocity considering the complete set of reactive strategies, where individuals behave conditionally on what they observed in the previous round. We study both analytically and by computer simulations the evolutionary dynamics encompassing this extensive strategy space, witnessing the emergence of a surprisingly simple strategy that we call All-Or-None (AoN). AoN consists in cooperating only after a round of unanimous group behavior (cooperation or defection), and proves robust in the presence of errors, thus fostering cooperation in a wide range of group sizes. The principles encapsulated in this strategy share a level of complexity reminiscent of that found already in 2-person games under direct and indirect reciprocity, reducing, in fact, to the well-known Win-Stay-Lose-Shift strategy in the limit of the repeated 2-person Prisoner's Dilemma.

  20. Cooperation and contagion in web-based, networked public goods experiments.

    A longstanding idea in the literature on human cooperation is that cooperation should be reinforced when conditional cooperators are more likely to interact. In the context of social networks, this idea implies that cooperation should fare better in highly clustered networks such as cliques than in networks with low clustering such as random networks. To test this hypothesis, we conducted a series of web-based experiments, in which 24 individuals played a local public goods game arranged on one of five network topologies that varied between disconnected cliques and a random regular graph. In contrast with previous theoretical work, we found that network topology had no significant effect on average contributions. This result implies either that individuals are not conditional cooperators, or else that cooperation does not benefit from positive reinforcement between connected neighbors. We then tested both of these possibilities in two subsequent series of experiments in which artificial seed players were introduced, making either full or zero contributions. First, we found that although players did generally behave like conditional cooperators, they were as likely to decrease their contributions in response to low contributing neighbors as they were to increase their contributions in response to high contributing neighbors. Second, we found that positive effects of cooperation were contagious only to direct neighbors in the network. In total we report on 113 human subjects experiments, highlighting the speed, flexibility, and cost-effectiveness of web-based experiments over those conducted in physical labs.

  1. Global public-private partnerships: Part II--What are the health issues for global governance?

    2000-01-01

    This is the second of a two-part review of global public-private partnerships (GPPPs) for health development. Part I was published in the April issue of the Bulletin (Vol. 78, No. 4). The recent emergence of GPPPs is rapidly reconfiguring the international health landscape. While most multilateral and bilateral agencies are currently grappling with how to proceed, there is little information in the public domain concerning how individual partnerships work and to date very little consideration of the many implications of this trend. This paper differentiates between product-based, product development-based and issues/systems-based GPPPs and describes a number of examples of each type in the health sector. The benefits of these initiatives, not least the major resources which they harness for specific health problems, are identified. The final section of the paper explores the implications and dilemmas posed by GPPPs. It discusses whether or not shared goals can transcend conflicting values and mandates and how governance of partnership arrangements may transform and undermine certain attributes of multilateral organizations. The paper concludes that the current climate of goodwill between public and private sectors offers an opportunity that should not be missed: it can be used not only to foster new partnership but to ensure that partnership is truly in the interests of international public health.

    Vaccine research and development are experiencing a renaissance of interest from the global scientific community. There are four major reasons for this: (1) the lack of efficacious treatment for many devastating infections; (2) the emergence of multidrug resistant bacteria; (3) the need for improving the safety of the more traditional licensed vaccines; and finally, (4) the great promise for innovative vaccine design and research with convergence of omics sciences, such as genomics, proteomics, immunomics, and vaccinology. Our first project based on omics was initiated in 2000 and was termed reverse vaccinology. At that time, antigen identification was mainly based on bioinformatic analysis of a singular genome. Since then, omics-guided approaches have been applied to its full potential in several proof-of-concept studies in the industry, with the first reverse vaccinology-derived vaccine now in late stage clinical trials and several vaccines developed by omics in preclinical studies. In the meantime, vaccine discovery and development has been further improved with the support of proteomics, functional genomics, comparative genomics, structural biology, and most recently vaccinomics. We illustrate in this review how omics biotechnologies and integrative biology are expected to accelerate the identification of vaccine candidates against difficult pathogens for which traditional vaccine development has thus far been failing, and how research will provide safer vaccines and improved formulations for immunocompromised patients in the near future. Finally, we present a discussion to situate omics-guided rational vaccine design in the broader context of global public health and how it can benefit citizens in both developed and developing countries.

    We evaluate the strengths and weaknesses of six publicly available global bathymetry grids: DBDB2 (Digital Bathymetric Data Base; an ongoing project of the Naval Research Laboratory), ETOPO2 (Earth Topography; National Geophysical Data Center, 2001, ETOPO2 Global 2’ Elevations [CD-ROM]. Boulder, Colorado, USA: U.S. Department of Commerce, National Oceanic and Atmospheric Administration), GEBCO (General Bathymetric Charts of the Oceans; British Oceanographic Data Centre, 2003, Centenary Edition of the GEBCO Digital Atlas [CD-ROM] Published on behalf of the Intergovernmental Oceanographic Commission and the International Hydrographic Organization Liverpool, UK), GINA (Geographic Information Network of Alaska; Lindquist et al., 2004), Smith and Sandwell (1997), and S2004 (Smith, unpublished). The Smith and Sandwell grid, derived from satellite altimetry and ship data combined, provides high resolution mapping of the seafloor, even in remote regions. DBDB2, ETOPO2, GINA, and S2004 merge additional datasets with the Smith and Sandwell grid; but moving from a pixel to grid registration attenuates short wavelengths (<20 km) in the ETOPO2 and DBDB2 solutions. Short wavelengths in the GINA grid are also attenuated, but the cause is not known. ETOPO2 anomalies are offset to the northeast, due to a misregistration in both latitude and longitude. The GEBCO grid is interpolated from 500 m contours that were digitized from paper charts at 1:10 million scale, so it is artificially smooth; yet new efforts have captured additional information from shallow water contours on navigational charts. The S2004 grid merges the Smith and Sandwell grid with GEBCO over shallow depths and polar regions, and so is intended to capture the best of both products. Our evaluation makes the choice of which bathymetry grid to use a more informed one.

    The Internet has become an important health information resource for patients and the general public. Wikipedia, a collaboratively written Web-based encyclopedia, has become the dominant online reference work. It is usually among the top results of search engine queries, including when medical information is sought. Since April 2004, editors have formed a group called WikiProject Medicine to coordinate and discuss the English-language Wikipedia’s medical content. This paper, written by members of the WikiProject Medicine, discusses the intricacies, strengths, and weaknesses of Wikipedia as a source of health information and compares it with other medical wikis. Medical professionals, their societies, patient groups, and institutions can help improve Wikipedia’s health-related entries. Several examples of partnerships already show that there is enthusiasm to strengthen Wikipedia’s biomedical content. Given its unique global reach, we believe its possibilities for use as a tool for worldwide health promotion are underestimated. We invite the medical community to join in editing Wikipedia, with the goal of providing people with free access to reliable, understandable, and up-to-date health information. PMID:21282098

  6. Mapping Phosphorus Imbalances in Croplands Globally: Too Much or Too Little of a Good Thing?

    Phosphorus (P) plays a key role linking ecosystems and society in that it is essential for agricultural production while also acting as a potential pollutant for aquatic ecosystems. Agricultural use of P fertilizers is by far the dominant anthropogenic influence on the global P cycle, and has resulted in accumulation of P in some agricultural soils that can contribute to water quality degradation. We mapped the spatial distribution of agricultural P balances at 0.5 degree resolution for cropland soils globally based on inputs of P via inorganic fertilizer and manure applications and outputs of P associated with production of more than 100 crops in the year 2000. Total agronomic inputs of P fertilizer and manure (23.8 Tg P yr-1) collectively exceeded P removal by harvested crops (12.3 Tg P yr-1) at the global scale, driving large P surpluses in many intensive agricultural regions (e.g., East Asia, Western Europe, and parts of South America). However, P deficits occurred in almost 30% of the global cropland area, including vast tracts of cropland in North and South America, Eastern Europe, and Africa. Our results show that use of inorganic P fertilizers in excess of crop requirements was the primary agronomic driver of the most intense P surpluses globally, and resulted in lower P input-use efficiency (kg crop produced ● kg P applied-1) in several regions compared to manure use. Widespread P deficits occurred predominantly in areas with extensive production of forage crops used as livestock feed, which challenges the notion that livestock production leads exclusively to P surpluses. This spatially-explicit data on cropland P imbalances provides new insight on how agricultural P use might interact with regional water quality and additionally shows the potential for soil P depletion that can negatively affect future agricultural productivity.

  7. Age-related differences in altruism across adulthood: making personal financial gain versus contributing to the public good.

    2014-04-01

    Four studies utilizing different methodological approaches investigated adult age-related differences in altruism (i.e., contributions to the public good) and the self-centered value of increasing personal wealth. In Study 1, data from the World Values Survey (World Values Survey Association, 2009) provided 1st evidence of a negative association between age and the self-reported wish to be rich. Ecological concerns, a form of contributing to the public good, were positively related to age. Study 2 investigated whether these values are expressed behaviorally when participants solved a complex problem that allowed striving for monetary gains or contributing to a public good. Confirming hypotheses, young adults' strategies were consistent with the aim of optimizing personal financial gain, and older adults' strategies with the aim to contribute to the public good. Studies 3 and 4 showed that older adults were more likely than younger and middle-aged adults to donate money to a good cause than to keep it for themselves. Study 4 manipulated participants' future time perspective as a factor potentially contributing to age-related differences. Partly confirming hypotheses, a longer time perspective reduced donations by older adults, but a shorter time perspective did not increase donations by younger adults. These studies suggest that older adults not only report valuing contributions to the public good more highly but also are more likely to behave altruistically than younger adults. All studies used cross-sectional designs that prevent a strict test of developmental trajectories but rather provide age-related differences at 1 point in time, representing a 1st step in investigating adult age-related differences in altruism.

    2011-01-01

    In recent decades, public health policy and practice have been increasingly challenged by globalization, even as global financing for health has increased dramatically. This article discusses globalization and its health challenges from a vantage of political science, emphasizing increased global flows (of pathogens, information, trade, finance, and people) as driving, and driven by, global market integration. This integration requires a shift in public health thinking from a singular focus on international health (the higher disease burden in poor countries) to a more nuanced analysis of global health (in which health risks in both poor and rich countries are seen as having inherently global causes and consequences). Several globalization-related pathways to health exist, two key ones of which are described: globalized diseases and economic vulnerabilities. The article concludes with a call for national governments, especially those of wealthier nations, to take greater account of global health and its social determinants in all their foreign policies.

  11. Mapping the global flow of aluminum: from liquid aluminum to end-use goods.

    2013-04-02

    Demand for aluminum in final products has increased 30-fold since 1950 to 45 million tonnes per year, with forecasts predicting this exceptional growth to continue so that demand will reach 2-3 times today's levels by 2050. Aluminum production uses 3.5% of global electricity and causes 1% of global CO2 emissions, while meeting a 50% cut in emissions by 2050 against growing demand would require at least a 75% reduction in CO2 emissions per tonne of aluminum produced--a challenging prospect. In this paper we trace the global flows of aluminum from liquid metal to final products, revealing for the first time a complete map of the aluminum system and providing a basis for future study of the emissions abatement potential of material efficiency. The resulting Sankey diagram also draws attention to two key issues. First, around half of all liquid aluminum (~39 Mt) produced each year never reaches a final product, and a detailed discussion of these high yield losses shows significant opportunities for improvement. Second, aluminum recycling, which avoids the high energy costs and emissions of electrolysis, requires signification "dilution" (~ 8 Mt) and "cascade" (~ 6 Mt) flows of higher aluminum grades to make up for the shortfall in scrap supply and to obtain the desired alloy mix, increasing the energy required for recycling.

  20. Too good to be true: publication bias in two prominent studies from experimental psychology.

    PubMed

    Francis, Gregory

    2012-04-01

    Empirical replication has long been considered the final arbiter of phenomena in science, but replication is undermined when there is evidence for publication bias. Evidence for publication bias in a set of experiments can be found when the observed number of rejections of the null hypothesis exceeds the expected number of rejections. Application of this test reveals evidence of publication bias in two prominent investigations from experimental psychology that have purported to reveal evidence of extrasensory perception and to indicate severe limitations of the scientific method. The presence of publication bias suggests that those investigations cannot be taken as proper scientific studies of such phenomena, because critical data are not available to the field. Publication bias could partly be avoided if experimental psychologists started using Bayesian data analysis techniques.

    PubMed

    Luke, Thomas C; Rodrigue, Jean-Paul

    2008-01-01

    The H5N1 influenza threat is resulting in global preparations for the next influenza pandemic. Pandemic influenza planners are prioritizing scarce vaccine, antivirals, and public health support for different segments of society. The freight, bulk goods, and energy transportation network comprise the maritime, rail, air, and trucking industries. It relies on small numbers of specialized workers who cannot be rapidly replaced if lost due to death, illness, or voluntary absenteeism. Because transportation networks link economies, provide critical infrastructures with working material, and supply citizens with necessary commodities, disrupted transportation systems can lead to cascading failures in social and economic systems. However, some pandemic influenza plans have assigned transportation workers a low priority for public health support, vaccine, and antivirals. The science of Transportation Geography demonstrates that transportation networks and workers are concentrated at, or funnel through, a small number of chokepoints and corridors. Chokepoints should be used to rapidly and efficiently vaccinate and prophylax the transportation worker cohort and to implement transmission prevention measures and thereby protect the ability to move goods. Nations, states, the transportation industry and unions, businesses, and other stakeholders must plan, resource, and exercise, and then conduct a transportation health assurance and security campaign for an influenza pandemic.

  4. What is "good reasoning" about global warming? A comparison of high school students and specialists

    NASA Astrophysics Data System (ADS)

    Adams, Stephen Thomas

    This study compares the knowledge and reasoning about global warming of 10 twelfth grade students and 6 specialists, including scientists and policy analysts. The study uses global warming as a context for addressing the broad objective of formulating goals for scientific literacy. Subjects evaluated a set of articles about global warming and evaluated policies proposed to ameliorate global warming, including a gasoline tax and a "feebate" system of fees and rebates on automobiles. All students and one scientist participated in a full treatment involving interviews and activities with a computer program (discussed below), averaging about 3.75 hours. In addition, five specialists participated in interviews only, averaging one hour. One line of analysis focuses on knowledge content, examining how subjects applied perspectives from both natural and social sciences. This analysis is positioned as an empirical component to the movement to develop content standards for science education, as exemplified by the recommendations of Science for All Americans (SFAA). Some aspects of competent performance in the present study hinged upon knowledge and skills advocated by SFAA (e.g., fluency with themes of science such as scale). Other aspects involved such skills as evaluating economic interests behind a scientific argument in the media or considering hidden costs in a policy area. By characterizing a range of approaches to how students and specialists performed the experimental tasks, the present study affords a view of scientific literacy not possible without this type of information. Another line of analysis investigates a measure of coherent argumentation from a computer program, Convince Me, in relation to policy reasoning. The program is based on a connectionist model, ECHO. Subjects used the program to create arguments about the aforementioned policies. The study compares Convince Me's Model's Fit argumentation measure to other measures, including ratings of 6 human

    PubMed

    Garlick, J A; Levine, P

    2016-07-07

    Public understanding of science and civic engagement on science issues that impact contemporary life matter more today than ever. From the Planned Parenthood controversy, to the Flint water crisis and the fluoridation debate, societal polarization about science issues has reached dramatic levels that present significant obstacles to public discussion and problem solving. This is happening, in part, because systems built to support science do not often reward open-minded thinking, inclusive dialogue, and moral responsibility regarding science issues. As a result, public faith in science continues to erode. This review explores how the field of Civic Science can impact public work on science issues by building new understanding of the practices, influences, and cultures of science. Civic Science is defined as a discipline that considers science practice and knowledge as resources for civic engagement, democratic action, and political change. This review considers how Civic Science informs the roles that key participants-scientists, public citizens and institutions of higher education-play in our national science dialogue. Civic Science aspires to teach civic capacities, to inform the responsibilities of scientists engaged in public science issues and to inspire an open-minded, inclusive dialogue where all voices are heard and shared commitments are acknowledged.

  7. Restructuring and the public good: Creating a national system benefits trust

    SciTech Connect

    Cowart, R.H.

    1997-04-01

    As part of electricity legislation, the country should consider establishing an electric system benefits trust, funded by a small wires surcharge, that would provide each state matching funds to carry on public benefits programs of its choice. Such an approach is working well in the telecom area and is perhaps even more needed in electricity reform. Restructuring the electric industry is one of the most challenging transformations under way in the nation today. State and federal efforts to reform this critical industry properly focus on capturing the benefits of competition and customer choice for customers of electricity. These are laudable goals, but insufficient by themselves. One must also secure and enhance the public benefits that until now have been provided by the electric industry`s unique structure and regulatory traditions. The means of securing these public objectives must be designed into any new regulatory structures from the outset, before dramatic changes unravel the gains this industry has made.

    Lymphocytes expressing a T cell receptor (TCR) composed of Vgamma9 and Vdelta2 chains represent a minor fraction of human thymocytes. Extrathymic selection throughout post-natal life causes the proportion of cells with a Vgamma9-JP rearrangement to increase and elevates the capacity for responding to non-peptidic phosphoantigens. Extrathymic selection is so powerful that phosphoantigen-reactive cells comprise about 1 in 40 circulating memory T cells in healthy adults and the subset expands rapidly upon infection or in response to malignancy. Skewing of the gamma delta TCR repertoire is accompanied by selection for public gamma chain sequences such that many unrelated individuals overlap extensive in their circulating repertoire. This type of selection implies the presence of a monomorphic antigen-presenting molecule that is an object of current research but remains incompletely defined. While selection on a monomorphic presenting molecule may seem unusual, similar mechanisms shape the alpha beta T cell repertoire including the extreme examples of NKT or mucosal-associated invariant T cells (MAIT) and the less dramatic amplification of public Vbeta chain rearrangements driven by individual MHC molecules and associated with resistance to viral pathogens. Selecting and amplifying public T cell receptors whether alpha beta or gamma delta, are important steps in developing an anticipatory TCR repertoire. Cell clones expressing public TCR can accelerate the kinetics of response to pathogens and impact host survival.

  7. Conflict and coordination in the provision of public goods: a conceptual analysis of continuous and step-level games.

    PubMed

    Abele, Susanne; Stasser, Garold; Chartier, Christopher

    2010-11-01

    Conflicts between individual and collective interests are ubiquitous in social life. Experimental studies have investigated the resolution of such conflicts using public goods games with either continuous or step-level payoff functions. Game theory and social interdependence theory identify consequential differences between these two types of games. Continuous function games are prime examples of social dilemmas because they always contain a conflict between individual and collective interests, whereas step-level games can be construed as social coordination games. Step-level games often provide opportunities for coordinated solutions that benefit both the collective and the individuals. For this and other reasons, the authors conclude that one cannot safely generalize results obtained from step-level to continuous-form games (or vice versa). Finally, the authors identify specific characteristics of the payoff function in public goods games that conceptually mark the transition from a pure dilemma to a coordination problem nested within a dilemma.

    There is little agreement about what constitutes good death or successful dying. The authors conducted a literature search for published, English-language, peer-reviewed reports of qualitative and quantitative studies that provided a definition of a good death. Stakeholders in these articles included patients, prebereaved and bereaved family members, and healthcare providers (HCPs). Definitions found were categorized into core themes and subthemes, and the frequency of each theme was determined by stakeholder (patients, family, HCPs) perspectives. Thirty-six studies met eligibility criteria, with 50% of patient perspective articles including individuals over age 60 years. We identified 11 core themes of good death: preferences for a specific dying process, pain-free status, religiosity/spirituality, emotional well-being, life completion, treatment preferences, dignity, family, quality of life, relationship with HCP, and other. The top three themes across all stakeholder groups were preferences for dying process (94% of reports), pain-free status (81%), and emotional well-being (64%). However, some discrepancies among the respondent groups were noted in the core themes: Family perspectives included life completion (80%), quality of life (70%), dignity (70%), and presence of family (70%) more frequently than did patient perspectives regarding those items (35%-55% each). In contrast, religiosity/spirituality was reported somewhat more often in patient perspectives (65%) than in family perspectives (50%). Taking into account the limitations of the literature, further research is needed on the impact of divergent perspectives on end-of-life care. Dialogues among the stakeholders for each individual must occur to ensure a good death from the most critical viewpoint-the patient's.

    This article presents the results of the first large-scale mail survey of non-residential green power customers in the United States. The survey explored the motivations, attitudes, and experiences of 464 business, non-profit, and public-sector customers that have voluntarily opted to purchase - and frequently pay a premium for - renewable electricity. Results of this study should be of value to marketers interested in targeting these customer segments, to policy makers interested in fostering and understanding non-residential demand for green power, and to academics pondering the motivations for firms to engage in such voluntary environmental initiatives.

    2016-01-01

    Given the broad scope and intersectoral nature of public health structures and practices, there are inherent difficulties in defining which services fall under the public health remit and in assessing their capacity and performance. The aim of this study is to analyze how public health functions and practice have been defined and operationalized in different countries and regions around the world, with a specific focus on assessment tools that have been developed to evaluate the performance of essential public health functions, services, and operations. Our review has identified nearly 100 countries that have carried out assessments, using diverse analytical and methodological approaches. The assessment processes have evolved quite differently according to administrative arrangements and resource availability, but some key contextual factors emerge that seem to favor policy-oriented follow-up. These include local ownership of the assessment process, policymakers' commitment to reform, and expert technical advice for implementation.

  12. Commercial influence and global nongovernmental public action in health and pharmaceutical policies.

    PubMed

    Koivusalo, Meri; Mackintosh, Maureen

    2011-01-01

    Nongovernmental public action has been effective in influencing global agenda-setting in health and pharmaceutical policies, yet its record in influencing solutions to the problems identified has been notably more limited. While trade policies have been particularly resistant to change, more substantial changes are observable in global health policies and global health governance. However, some of the directions of change may not be conducive to the democratic accountability of global health governance, to the wise use of public resources, to health systems development, or to longer-term access to health care within developing countries. The authors argue that observed changes in global health policies can be understood as accommodating to corporate concerns and priorities. Furthermore, the changing global context and the commercialization of global public action itself pose sharp challenges to the exercise of influence by global nongovernmental public actors. Nongovernmental organizations not only face a major challenge in terms of the imbalance in power and resources between themselves and corporate interest groups when seeking to influence policymaking; they also face the problem of corporate influence on public action itself.

  13. Adapting public policy theory for public health research: A framework to understand the development of national policies on global health.

    PubMed

    Jones, Catherine M; Clavier, Carole; Potvin, Louise

    2017-03-01

    National policies on global health appear as one way that actors from health, development and foreign affairs sectors in a country coordinate state action on global health. Next to a burgeoning literature in which international relations and global governance theories are employed to understand global health policy and global health diplomacy at the international level, little is known about policy processes for global health at the national scale. We propose a framework of the policy process to understand how such policies are developed, and we identify challenges for public health researchers integrating conceptual tools from political science. We developed the framework using a two-step process: 1) reviewing literature to establish criteria for selecting a theoretical framework fit for this purpose, and 2) adapting Real-Dato's synthesis framework to integrate a cognitive approach to public policy within a constructivist perspective. Our framework identifies multiple contexts as part of the policy process, focuses on situations where actors work together to make national policy on global health, considers these interactive situations as spaces for observing external influences on policy change and proposes policy design as the output of the process. We suggest that this framework makes three contributions to the conceptualisation of national policy on global health as a research object. First, it emphasizes collective action over decisions of individual policy actors. Second, it conceptualises the policy process as organised interactive spaces for collaboration rather than as stages of a policy cycle. Third, national decision-making spaces are opportunities for transferring ideas and knowledge from different sectors and settings, and represent opportunities to identify international influences on a country's global health policy. We discuss two sets of challenges for public health researchers using interdisciplinary approaches in policy research.

    2016-02-01

    In June 2015 the German Academies of Science and Technology published a report on the structures, developments and challenges in the field of public and global health in Germany. Its call for a strengthening of public and global health in Germany was well received among researchers and practitioners in the field. At the same time criticism arose. Key controversies relate to the future institutional set-up of public and global health research in Germany, the consideration of the social determinants of health versus biomedical and technological approaches, the need for further research versus the need for political implementation of what is already known, and the consideration of the political context, such as intellectual property rights. This contribution provides an overview on the debate and lays down the perspective of the German Medical Students' Association (bvmd) and the Globalisation and Health Initiative (GandHI), putting forward demands regarding the role of public and global health in medical education in Germany.

    Since the end of the Cold War, there has been a dramatic increase in civil conflicts resulting in approximately 50 million refugees and internally displaced civilians. The public health impact of these situations has been immense, comprising high rates of communicable diseases, elevated prevalence of acute malnutrition, and high excess mortality rates. The prevention of these adverse public health effects includes early warning and intervention; prompt supply of adequate food, water, and sanitation; measles immunization; effective management of epidemic communicable diseases; and simple and timely information systems.

  18. Selection of the distributional rule as an alternative tool to foster cooperation in a Public Good Game

    2017-02-01

    This paper presents an investigation about cooperation in a Public Good Game using an Agent Based Model calibrated on experimental data. Starting from the experiment proposed in Colasante and Russo (2016), we analyze the dynamic of cooperation in a Public Good Game where agents receive an heterogeneous income and choose both the level of contribution and the distribution rule. The starting point is the calibration and the output validation of the model using the experimental results. Once tested the goodness of fit of the Agent Based Model, we run some policy experiment in order to verify how each distribution rule, i.e. equidistribution, proportional to contribution and progressive, affects the level of contribution in the simulated model. We find out that the share of cooperators decreases over time if we exogenously set the equidistribution rule. On the contrary, the share of cooperators converges to 100 % if we impose the progressive rule. Finally, the most interesting result refers to the effect of the progressive rule. We observe that, in the case of high inequality, this rule is not able to reduce the heterogeneity of income.

  19. Lessons from the 'Humanitarian Golden Rice' project: regulation prevents development of public good genetically engineered crop products.

    PubMed

    Potrykus, Ingo

    2010-11-30

    Compared to a non-Genetically Engineered (GE) variety, the deployment of Golden Rice has suffered from a delay of at least ten years. The cause of this delay is exclusively GE-regulation. Considering the potential impact of Golden Rice on the reduction in vitamin A-malnutrition, this delay is responsible for an unjustifiable loss of millions of lives, mostly children and women. GE-regulation is also responsible for the fact that no public institution can deliver a public good GE-product and that thus we have a de facto monopoly in favour of a few potent industries. Considering the forgone benefits from prevented public good GE-products, GE-regulation is responsible for hundreds of millions of lives, all of them, of course, in developing countries. As there is no scientific justification for present GE-regulation, and as it has, so far, not prevented any harm, our society has the urgent responsibility to reconsider present regulation, which is based on an extreme interpretation of the precautionary principle, and change it to science-based regulation on the basis of traits instead of technology. GE-technology has an unprecedented safety record and is far more precise and predictable than any other 'traditional' and unregulated breeding technology. Not to change GE-regulation to a scientific basis is considered by the author 'a crime against humanity'.

    2010-05-01

    The United Nations Environment Programme (UNEP), via its official collaborating center in Norway, GRID-Arendal, is in the process of implementing a Global Assessment of Methane Gas Hydrates. Global reservoirs of methane gas have long been the topic of scientific discussion both in the realm of environmental issues such as natural forces of climate change and as a potential energy resource for economic development. Of particular interest are the volumes of methane locked away in frozen molecules known as clathrates or hydrates. Our rapidly evolving scientific knowledge and technological development related to methane hydrates makes these formations increasingly prospective to economic development. In addition, global demand for energy continues, and will continue to outpace supply for the foreseeable future, resulting in pressure to expand development activities, with associated concerns about environmental and social impacts. Understanding the intricate links between methane hydrates and 1) natural and anthropogenic contributions to climate change, 2) their role in the carbon cycle (e.g. ocean chemistry) and 3) the environmental and socio-economic impacts of extraction, are key factors in making good decisions that promote sustainable development. As policy makers, environmental organizations and private sector interests seek to forward their respective agendas which tend to be weighted towards applied research, there is a clear and imminent need for a an authoritative source of accessible information on various topics related to methane gas hydrates. The 2008 United Nations Environment Programme Annual Report highlighted methane from the Arctic as an emerging challenge with respect to climate change and other environmental issues. Building upon this foundation, UNEP/GRID-Arendal, in conjunction with experts from national hydrates research groups from Canada, the US, Japan, Germany, Norway, India and Korea, aims to provide a multi-thematic overview of the key

    The globalization of public health is both real and relevant throughout the United States and to Americans traveling or residing abroad. US public policy responses are evolving, but a crisper and more comprehensive global perspective is needed. I suggest four timely US actions to address today’s competing realities of globalization and economic austerity: raise awareness among clinicians and local health departments; capture and share exemplary disaster management practices across countries; ensure that US global health investments are effective, efficient, and sustainable; and think globally while acting locally to enhance US health security. The reauthorization of the Pandemic and All-Hazards Preparedness Act of 2006 provides an opportunity to more clearly address the global dimensions of domestic preparedness. PMID:22515870

    1996-12-31

    Modeling projections of future climatic conditions suggest changes in temperature and precipitation patterns that might induce direct adverse effects on human health by altering the extent and severity of infectious and vector-borne diseases. The incidence of mosquito-borne diseases, for example, could increase substantially in areas where temperature and relative humidity rise. The application of Geographic Information Systems (GIS) offers new methodologies to evaluate the impact of global warming on changes in the incidence of infectious and vector-borne diseases. This research illustrates the potential analytical and communication uses of GIS for monitoring historical patterns of climate and human health variables and for projecting changes in these health variables with global warming.

  9. Siderophore production and the evolution of investment in a public good: An adaptive dynamics approach to kin selection.

    PubMed

    2016-01-07

    Like many other bacteria, Pseudomonas aeruginosa sequesters iron from the environment through the secretion, and subsequent uptake, of iron-binding molecules. As these molecules can be taken up by other bacteria in the population than those who secreted them, this is a form of cooperation through a public good. Traditionally, this problem has been studied by comparing the relative fitnesses of siderophore-producing and non-producing strains, but this gives no information about the fate of strains that do produce intermediate amounts of siderophores. Here, we investigate theoretically how the amount invested in this form of cooperation evolves. We use a mechanistic description of the laboratory protocols used in experimental evolution studies to describe the competition and cooperation of the bacteria. From this dynamical model we derive the fitness following the adaptive dynamics method. The results show how selection is driven by local siderophore production and local competition. Because siderophore production reduces the growth rate, local competition decreases with the degree of relatedness (which is a dynamical variable in our model). Our model is not restricted to the analysis of small phenotypic differences and allows for theoretical exploration of the effects of large phenotypic differences between cooperators and cheats. We predict that an intermediate ESS level of cooperation (molecule production) should exist. The adaptive dynamics approach allows us to assess evolutionary stability, which is often not possible in other kin-selection models. We found that selection can lead to an intermediate strategy which in our model is always evolutionarily stable, yet can allow invasion of strategies that are much more cooperative. Our model describes the evolution of a public good in the context of the ecology of the microorganism, which allows us to relate the extent of production of the public good to the details of the interactions.

  10. Access to nutritious food, socioeconomic individualism and public health ethics in the USA: a common good approach

    2013-01-01

    Good nutrition plays an important role in the optimal growth, development, health and well-being of individuals in all stages of life. Healthy eating can reduce the risk of chronic diseases, such as heart disease, stroke, diabetes and some types of cancer. However, the capitalist mindset that shapes the food environment has led to the commoditization of food. Food is not just a marketable commodity like any other commodity. Food is different from other commodities on the market in that it is explicitly and intrinsically linked to our human existence. While possessing another commodity allows for social benefits, food ensures survival. Millions of people in United States of America are either malnourished or food insecure. The purpose of this paper is to present a critique of the current food system using four meanings of the common good--as a framework, rhetorical device, ethical concept and practical tool for social justice. The first section of this paper provides a general overview of the notion of the common good. The second section outlines how each of the four meanings of the common good helps us understand public practices, social policies and market values that shape the distal causal factors of nutritious food inaccessibility. We then outline policy and empowerment initiatives for nutritious food access. PMID:24165577

The purpose of this paper is to present a critique of the current food system using four meanings of the common good--as a framework, rhetorical device, ethical concept and practical tool for social justice. The first section of this paper provides a general overview of the notion of the common good. The second section outlines how each of the four meanings of the common good helps us understand public practices, social policies and market values that shape the distal causal factors of nutritious food inaccessibility. We then outline policy and empowerment initiatives for nutritious food access.

  12. Mass Communication, Public Communication, and Interpersonal Communication: A Global Model for International Public Relations.

    A participatory model of public relations proposed by Dean Kruckeberg and Kenneth Starck would seek not to serve a public but to build a sense of community. In this model the advocacy focus of the publicity model is dropped and there is a movement toward relationships rather than selling products and services. Leaving behind the journalistic…

    Lead is the most abundant of the heavy metals in the Earth's crust. It has been used since prehistoric times, and has become widely distributed and mobilized in the environment. Exposure to and uptake of this non-essential element have consequently increased. Both occupational and environmental exposures to lead remain a serious problem in many developing and industrializing countries, as well as in some developed countries. In most developed countries, however, introduction of lead into the human environment has decreased in recent years, largely due to public health campaigns and a decline in its commercial usage, particularly in petrol. Acute lead poisoning has become rare in such countries, but chronic exposure to low levels of the metal is still a public health issue, especially among some minorities and socioeconomically disadvantaged groups. In developing countries, awareness of the public health impact of exposure to lead is growing but relatively few of these countries have introduced policies and regulations for significantly combating the problem. This article reviews the nature and importance of environmental exposure to lead in developing and developed countries, outlining past actions, and indicating requirements for future policy responses and interventions.

  15. Globalizing the history of disease, medicine, and public health in Latin America.

    Espinosa, Mariola

    2013-12-01

    The history of Latin America, the history of disease, medicine, and public health, and global history are deeply intertwined, but the intersection of these three fields has not yet attracted sustained attention from historians. Recent developments in the historiography of disease, medicine, and public health in Latin America suggest, however, that a distinctive, global approach to the topic is beginning to emerge. This essay identifies the distinguishing characteristic of this approach as an attentiveness to transfers of contagions, cures, and medical knowledge from Latin America to the rest of the world and then summarizes a few episodes that demonstrate its promise. While national as well as colonial and neocolonial histories of Latin America have made important contributions to our understanding, works taking the global approach have the potential to contribute more directly to the decentering of the global history of disease, medicine, and public health.

  16. The influence of global warming on natural disasters and their public health outcomes.

    PubMed

    Diaz, James H

    2007-01-01

    With a documented increase in average global surface temperatures of 0.6 degrees C since 1975, Earth now appears to be warming due to a variety of climatic effects, most notably the cascading effects of greenhouse gas emissions resulting from human activities. There remains, however, no universal agreement on how rapidly, regionally, or asymmetrically the planet will warm or on the true impact of global warming on natural disasters and public health outcomes. Most reports to date of the public health impact of global warming have been anecdotal and retrospective in design and have focused on the increase in heat-stroke deaths following heat waves and on outbreaks of airborne and arthropod-borne diseases following tropical rains and flooding that resulted from fluctuations in ocean temperatures. The effects of global warming on rainfall and drought, tropical cyclone and tsunami activity, and tectonic and volcanic activity will have far-reaching public health effects not only on environmentally associated disease outbreaks but also on global food supplies and population movements. As a result of these and other recognized associations between climate change and public health consequences, many of which have been confounded by deficiencies in public health infrastructure and scientific debates over whether climate changes are spawned by atmospheric cycles or anthropogenic influences, the active responses to progressive climate change must include combinations of economic, environmental, legal, regulatory, and, most importantly, public health measures.

    Objective To gather information about current practices and implementation of publication guidelines among publication professionals working in or for the pharmaceutical industry. Design/setting Web-based survey publicised via email and social media to members of the International Society for Medical Publication Professionals (ISMPP) and other organisations from November 2012 to February 2013. Participants 469 individuals involved in publishing industry-sponsored research in peer-reviewed journals, mainly working in pharmaceutical or device companies (‘industry’, n=144), communication agencies (‘agency’, n=238), contract research organisations (CRO, n=15) or as freelancers (n=34). Most respondents (78%) had worked on medical publications for ≥5 years and 62% had a PhD/MD. Results Over 90% of industry, agency and CRO respondents routinely refer to Good Publication Practice (GPP2) and the International Committee of Medical Journal Editors’ Uniform Requirements. Most respondents (78% industry, 79% agency) received mandatory training on ethical publication practices. Over 90% of respondents’ companies had publication guidelines or policies and required medical writing support to be acknowledged in publications (96% industry, 99% agency). Many industry respondents used publication management tools to monitor compliance with company guidelines and about half (46%) stated that their company had formal publication audits. Fewer agencies audited adherence to guidelines but 20% of agency respondents reported audits of employees and 6% audits of freelancers. Of concern, 37% of agency respondents reported requests from authors or sponsors that they believed were unethical, although 93% of these requests were withdrawn after respondents explained the need for compliance with guidelines. Most respondents’ departments (63% industry, 58% agency, 60% CRO) had been involved in publishing studies with negative or inconclusive results. Conclusions Within this sample

    The declaration in 2009 that the H1N1 pandemic constituted a public health emergency of international concern (PHEIC) was the first such declaration under the revised International Health Regulations that were adopted in 2005. In the period since then PHEIC have been declared in relation to polio, Ebola, and Zika. This article evaluates initiatives that have been introduced globally, within the Asia-Pacific region, and within Australia, to strengthen preparedness for public health emergencies. Through analysis of evolving conceptualisations of risk, surveillance of zoonotic diseases, and development of public health capacities, the article argues that to date the global community has failed to make the necessary investments in health system strengthening, and that without these investments, global public health emergencies will continue to be an ongoing challenge.

    During the last decade, the literature about global health has grown exponentially. Academic institutions are also exploring the scope of their public health educational programs to meet the demand for a global health professional. This has become more relevant in the context of the sustainable development goals. There have been attempts to describe global health competencies for specific professional groups. The focus of these competencies has been variable with a variety of different themes being described ranging from globalization and health care, analysis and program management, as well as equity and capacity strengthening. This review aims to describe global health competencies and attempts to distill common competency domains to assist in curriculum development and integration in postgraduate public health education programs. A literature search was conducted using relevant keywords with a focus on public health education. This resulted in identification of 13 articles that described global health competencies. All these articles were published between 2005 and 2015 with six from the USA, two each from Canada and Australia, and one each from UK, Europe, and Americas. A range of methods used to describe competency domains included literature review, interviews with experts and employers, surveys of staff and students, and description or review of an academic program. Eleven competency domains were distilled from the selected articles. These competency domains primarily referred to three main aspects, one that focuses on burden of disease and the determinants of health. A second set focuses on core public health skills including policy development, analysis, and program management. Another set of competency domains could be classified as "soft skills" and includes collaboration, partnering, communication, professionalism, capacity building, and political awareness.

  20. The Effect of Ostracism and Optional Participation on the Evolution of Cooperation in the Voluntary Public Goods Game

    2014-01-01

    Not only animals, plants and microbes but also humans cooperate in groups. The evolution of cooperation in a group is an evolutionary puzzle, because defectors always obtain a higher benefit than cooperators. When people participate in a group, they evaluate group member’s reputations and then decide whether to participate in it. In some groups, membership is open to all who are willing to participate in the group. In other groups, a candidate is excluded from membership if group members regard the candidate’s reputation as bad. We developed an evolutionary game model and investigated how participation in groups and ostracism influence the evolution of cooperation in groups when group members play the voluntary public goods game, by means of computer simulation. When group membership is open to all candidates and those candidates can decide whether to participate in a group, cooperation cannot be sustainable. However, cooperation is sustainable when a candidate cannot be a member unless all group members admit them to membership. Therefore, it is not participation in a group but rather ostracism, which functions as costless punishment on defectors, that is essential to sustain cooperation in the voluntary public goods game.

  1. The inter-group comparison-intra-group cooperation hypothesis: comparisons between groups increase efficiency in public goods provision.

    Identifying methods to increase cooperation and efficiency in public goods provision is of vital interest for human societies. The methods that have been proposed often incur costs that (more than) destroy the efficiency gains through increased cooperation. It has for example been shown that inter-group conflict increases intra-group cooperation, however at the cost of collective efficiency. We propose a new method that makes use of the positive effects associated with inter-group competition but avoids the detrimental (cost) effects of a structural conflict. We show that the mere comparison to another structurally independent group increases both the level of intra-group cooperation and overall efficiency. The advantage of this new method is that it directly transfers the benefits from increased cooperation into increased efficiency. In repeated public goods provision we experimentally manipulated the participants' level of contribution feedback (intra-group only vs. both intra- and inter-group) as well as the provision environment (smaller groups with higher individual benefits from cooperation vs. larger groups with lower individual benefits from cooperation). Irrespective of the provision environment groups with an inter-group comparison opportunity exhibited a significantly stronger cooperation than groups without this opportunity. Participants conditionally cooperated within their group and additionally acted to advance their group to not fall behind the other group. The individual efforts to advance the own group cushion the downward trend in the above average contributors and thus render contributions on a higher level. We discuss areas of practical application.

  5. Social justice and social responsibility: towards a value-base for global public health.

    PubMed

    Mackie, P

    2010-11-01

    Public health and social justice have been seen as one and the same thing, in that public health is - of its very nature - socially just. In this paper, the relationship between public health and social justice is explored through reflecting upon the definitions of the two. Work being undertaken in Scotland in relation to prison health shows that public health action can be intended to have a socially just consequence. However it is not always possible to show that social justice was always the intended outcome of a public health action, as economic intentions can often result in similar public health intervention. In seeking to set out a values base for Global Public Health, the reflection allows two overarching values to be proposed: equality and mutuality.

    2007-01-01

    Health equity remains a major challenge to policymakers despite the resurgence of interest to promote it. In developing countries, especially, the sheer inadequacy of financial and human resources for health and the progressive undermining of state capacity in many under-resourced settings have made it extremely difficult to promote and achieve significant improvements in equity in health and access to healthcare. In the last decade, public-private partnerships have been explored as a mechanism to mobilise additional resources and support for health activities, notably in resource-poor countries. While public-private partnerships are conceptually appealing, many concerns have been raised regarding their impact on global health equity. This paper examines the viability of public-private partnerships for improving global health equity and highlights some key prospects and challenges. The focus is on global health partnerships and excludes domestic public-private mechanisms such as the state contracting out publicly-financed health delivery or management responsibilities to private partners. The paper is intended to stimulate further debate on the implications of public-private partnerships for global health equity.

    Climatic change potentially causes direct and indirect impacts on human health, resulting in a net increase in morbidity and associated mortality. Impacts would be greater in communities with higher exposure and with fewer technical and social resources. Age, skin pigmentation, hygiene level, socio-economic and health status, are determinants of the net effects. Climatic change will have indirect health effects by changing natural ecosystems, affecting such aspects as food production, patterns of vector-borne diseases, a number of non-infectious diseases, and unknown infections. The health effects, occurring largely as a result of increases in biologically effective UVR, are expected to consist of: increase in malignant and nonmalignant skin cancer; several eye diseases (primarily cataract); and possible alterations in the immune response. Some of the largest public health issues will be respiratory diseases brought about by increased air pollution, exacerbation of allergic disorders, and deaths and injuries from extreme weather events. Additionally, vaccination programs may be ineffective and nutritional requirements may be different in heavily sun-exposed populations.

  8. Pharmaceutical digital marketing and governance: illicit actors and challenges to global patient safety and public health

    2013-01-01

    Background Digital forms of direct-to-consumer pharmaceutical marketing (eDTCA) have globalized in an era of free and open information exchange. Yet, the unregulated expansion of eDTCA has resulted in unaddressed global public health threats. Specifically, illicit online pharmacies are engaged in the sale of purportedly safe, legitimate product that may in fact be counterfeit or substandard. These cybercriminal actors exploit available eDTCA mediums over the Internet to market their suspect products globally. Despite these risks, a detailed assessment of the public health, patient safety, and cybersecurity threats and governance mechanisms to address them has not been conducted. Discussion Illicit online pharmacies represent a significant global public health and patient safety risk. Existing governance mechanisms are insufficient and include lack of adequate adoption in national regulation, ineffective voluntary governance mechanisms, and uneven global law enforcement efforts that have allowed proliferation of these cybercriminals on the web. In order to effectively address this multistakeholder threat, inclusive global governance strategies that engage the information technology, law enforcement and public health sectors should be established. Summary Effective global “eHealth Governance” focused on cybercrime is needed in order to effectively combat illicit online pharmacies. This includes building upon existing Internet governance structures and coordinating partnership between the UN Office of Drugs and Crime that leads the global fight against transnational organized crime and the Internet Governance Forum that is shaping the future of Internet governance. Through a UNODC-IGF governance mechanism, investigation, detection and coordination of activities against illicit online pharmacies and their misuse of eDTCA can commence. PMID:24131576

    Health, government, and media organizations around the world have responded to research demonstrating the imitative effects of suicide coverage in the news media by developing guidelines to foster responsible reporting. Implementation of these guidelines has encountered some resistance, and little is known about the media perspective on suicide coverage and its effects on guideline use. This qualitative study provides an in-depth appreciation of this perspective by investigating the experiences of journalists covering suicide in New Zealand. Fifteen newspaper, television and radio journalists were interviewed between December 2008 and March 2009 and transcripts were analyzed using a grounded hermeneutic editing approach. Five themes were identified: public responsibility, media framing of suicide, professional practice, personal experience of suicide reporting, and restricted reporting. Participants asserted the role of the media in the protection of the public good. Though this stance aligns them with the goals of health policymakers, it is derived from a set of professional mores at odds with the perceived paternalism of suicide reporting guidelines. Participants were stakeholders in the issue of suicide coverage. We conclude that policymakers must engage with the news media and acknowledge the competing imperatives that provide the context for the application of suicide reporting guidelines by individual journalists. Collaborative guideline development will be vital to effective implementation.

    2015-12-01

    Three major global problems of our times are global warming, air pollution mortality and morbidity, and energy insecurity. Whereas, policy makers with the support of the public must implement solutions to these problems, it is scientists and engineers who are best equipped to evaluate technically sound, optimal, and efficient solutions. Yet, a disconnect exists between information provided by scientists and engineers and policies implemented. Part of the reason is that scientific information provided to policy makers and the public is swamped out by information provided by lobbyists and another part is the difficulty in providing information to the hundreds of millions of people who need it rather than to just a few thousand. What other ways are available, aside from issuing press releases on scientific papers, for scientists to disseminate information? Three growing methods are through social media, creative media, and storytelling. The Solutions Project is a non-profit non-governmental organization whose goal is to bring forth scientific information about 100% clean, renewable energy plans to the public, businesses, and policy makers using these and related tools. Through the use of social media, the development of engaging internet and video content, and storytelling, the group hopes to increase the dissemination of information for social good. This talk discusses the history and impacts to date of this group and its methods. Please see www.thesolutionsproject.org and 100.org for more information.

Increasingly, natural disasters result in failure of public health and security systems leading to preventable conflict, unconventional war and unprecedented population migration. While scientific expertise exists to mitigate these failures in fragile states and ungoverned territories, inactions are mired by the lack of political will, international legal mandates, and capacity to strategically monitor multidisciplinary public health indicator failures.

Despite the now burgeoning literature that describes specific knowledge, attitudes, and skills that promote cultural “competence,” fully defining this complex, multidimensional term and implementing activities to enhance it remain a challenge. We describe our experiences in introducing a mandatory, full-day workshop to incoming Master of Public Health students, called “Self, Social, and Global Awareness: Personal Capacity Building for Professional Education and Practice.” The purpose of the program is to provide a meaningful, structured environment to explore issues of culture, power, privilege, and social justice, emphasizing the centrality of these issues in effective public health education and practice.

    2012-01-01

    A survey of global health experts attending an invited meeting provided a means to map key issues perceived to be shaping emerging global public health agendas. Eighty-five participants proposed three major issues likely to have the most significant impact on the field of global health in the coming years. Six raters grouped the resultant items, with multi-dimensional scaling (MDS) analysis producing a composite two-dimensional map depicting the overall patterning of items. Thematic clusters were incorporated within four major domains: changing health and prevention needs (15% of items), globalisation and global health governance (33% of items), transforming health systems (30% of items) and innovations in science and technology (7% of items). The remaining 15% of items addressed forms of environmental change. The distribution of items across domains was not significantly influenced by the current professional role of participants, their current location in the 'global north' or 'global south' or their region of focus (although the latter approached threshold significance). The constraints on interpretation imposed by the biases influencing participation in the survey are noted. However, the exercise suggests the potential for coherently defining shared agendas for diverse stakeholders to address emerging priorities. The closer integration of environmental concerns with other global public issues is clearly warranted.

    2015-01-01

    Abstract Background: Interactive games that highlight global health challenges and solutions are a potential tool for increasing interest in global health. To test this hypothesis, we developed an interactive “Polio Eradication” (PE) game and evaluated whether playing or watching was associated with increased public interest in global health. Materials and Methods: The PE game is a life-size, human board game that simulates PE efforts. Four players—a researcher, a transportation expert, a local community coordinator, and a healthcare worker—collaborate as an interdisciplinary team to help limit ongoing and future polio outbreaks in Pakistan, represented on the game board. Participants who played or observed the game and those who did not participate in the game, but visited noninteractive global health exhibits, completed a survey on participation outcomes. We used relative risk regression to examine associations between cofactors and change in global health interest. Results: Three variables predicted increased global health interest among the game participants: Having little or no previous global health knowledge prior to playing the game (risk ratio [RR]=1.28; 95 percent confidence interval [CI], 1.13–1.45), not currently being involved in global health (RR=1.41; 95 percent CI, 1.07–1.85), and visiting Seattle (RR=1.25; 95 percent CI, 1.04–1.51). Conclusions: Our results suggest that a hands-on, interactive game may increase the public's interest in global health, particularly among those with minimal previous knowledge of or involvement in global health activities.

    A confluence of stimuli is propelling academic public health to embrace the prevention of chronic disease in developing countries as its new frontier. These stimuli are a growing recognition of the epidemic, academia's call to reestablish public health as a mover of societal tectonics rather than a handmaiden to medicine's focus on the individual, and the turmoil in the US health system that makes change permissible. To enable graduating professionals to participate in the assault on chronic diseases, schools of public health must allocate budgets and other resources to this effort. The barriers to chronic disease prevention and risk factor modulation are cultural and political; confronting them will require public health to work with a wide variety of disciplines. Chronic disease will likely become the dominant global public health issue soon. In addressing this issue, academia needs to lead, not follow. PMID:21680924

    Health observatories may differ according to their mission, institutional setting, topical emphasis or geographic coverage. This paper discusses the development of a new urban-focused health observatory, and its operational research and training infrastructure under the academic umbrella of the Department of Epidemiology and the Institute of Urban Health at the Johns Hopkins Bloomberg School of Public Health (BSPH) in Baltimore, USA. Recognizing the higher education mission of the BSPH, the development of a new professional training in public health was an important first step for the development of this observatory. This new academia-based observatory is an innovative public health research and training platform offering faculty, investigators, professional epidemiology students and research partners a physical and methodological infrastructure for their operational research and training activities with both a local urban focus and a global reach. The concept of a public health observatory and its role in addressing social health inequalities in local urban settings is discussed.

  5. The vulnerability of being ill informed: the Trans-Pacific Partnership Agreement and Global Public Health.

    The Trans Pacific Partnership Agreement (TPPA) is a regional trade agreement currently being negotiated by 11 Pacific Rim countries, excluding China. While the negotiations are being conducted under a veil of secrecy, substantive leaks over the past 4 years have revealed a broad view of the proposed contents. As it stands the TPPA poses serious risks to global public health, particularly chronic, non-communicable diseases. At greatest risk are national tobacco regulations, regulations governing the emergence of generic drugs and controls over food imports by transnational corporations. Aside from a small group of public health professionals from Australia, the academic public health community has missed these threats to the global community, although many other health-related entities, international lawyers and health-conscious politicians have voiced serious concerns. As of mid-2014 there has been no comment in the leading public health journals. This large lacuna in interest or recognition reflects the larger problem that the public health education community has all but ignored global non-communicable diseases. Without such a focus, the risks are unseen and the threats not perceived. This cautionary tale of the TPPA reflects the vulnerability of being ill informed of contemporary realities.

    Counterfeit drugs are a global problem with significant and well-documented consequences for global health and patient safety, including drug resistance and patient deaths. This multibillion-dollar industry does not respect geopolitical borders, and threatens public health in both rich and resource-poor nations alike. The epidemiology of counterfeits is also wide in breadth and scope, including thousands of counterfeit incidents per year, encompassing all types of therapeutic classes, and employing a complex global supply chain network enabling this illegal activity. In addition, information technologies available through the Internet and sales via online pharmacies have allowed the criminal element to thrive in an unregulated environment of anonymity, deception, and lack of adequate enforcement. Though recent global enforcement efforts have led to arrests of online counterfeit sellers, such actions have not stemmed supplies from illegal online sellers or kept up with their creativity in illegally selling their products. To address this issue, we propose a global policy framework utilizing public-private partnership models with centralized surveillance reporting that would enable cooperation and coordination to combat this global health crisis.

    The appropriate role of innovation and intellectual property (IP) in global public health is a controversial issue. Discussion is one-sided, with potential benefits advocated by industry in stark contrast to condemnation by certain civil society players. WHO's Public Health, Innovation and Intellectual Property Department (PHI) was established to address healthcare resource need for developing countries, assess impact of innovation and IP on access to medicines, explore innovative funding mechanisms for R&D and provide evidence-based policy-making recommendations in response to the changing global health landscape. Importantly, PHI could represent a potential forum to bridge shared, yet often diverse, interests and opportunities between various public and private stakeholders, a crucial issue for ensuring the future viability of WHO.

  9. Globalized public health.” A transdisciplinary comprehensive framework for analyzing contemporary globalization’s influences on the field of public health

    2009-01-01

    The current phase of globalization represents a “double-edged sword” challenge facing public health practitioners and health policy makers. The first “edge” throws light on two constructs in the field of public health: global health (formerly international health) and globalized public health. The second “edge” is that of global governance, and raises the question, “how can we construct public health regulations that adequately respond to both global and local complexities related to the two constructs mentioned earlier (global health and globalized public health)?” The two constructs call for the development of norms that will assure sustained population-wide health improvement and these two constructs have their own conceptual tools and theoretical models that permit a better understanding of them. In this paper, we introduce the “globalized public health” construct and we present an interactive comprehensive framework for critically analyzing contemporary globalization’s influences on the field of public health. “Globalized public health”, simultaneously a theoretical model and a conceptual framework, concerns the transformation of the field of public health in the sociohistorical context of globalization. The model is the fruit of an original theoretical research study conducted from 2005 to 2008 (“contextualized research,” Gibbons’ Mode II of knowledge production), founded on a QUAL-quant sequential mixed-method design. This research also reflects our political and ideological position, fuelled with aspirations of social democracy and cosmopolitical values. It is profoundly anchored in the pragmatic approach to globalization, looking to “reconcile” the market and equity. The model offers several features to users: (1) it is transdisciplinary; (2) it is interactive (CD-ROM); (3) it is nonlinear (nonlinear interrelations between the contextual globalization and the field of public health); (4) it is synchronic/diachronic (a

    Survey data from a representative sample of 1005 households in the UK coastal city of Portsmouth are examined to discern commonalities and contrasts in their assessment of actions to address the related environmental threats of climate change and flooding. The city of Portsmouth is at risk of inundation from rising sea levels and the city has recent experience of flooding. A simple local and global public good framework is used to organize the understanding of reported attitudes and their determinants. The findings show that it is not always the same individuals who express concern about both climate change and flooding. Investigation into perceptions of helplessness in tackling climate change indicates that individuals more often perceived themselves to be helpless in tackling climate but perceived local collective action to be more effective. Individuals considered local collective action to be more effective in tackling climate change. Perceptions of individual helplessness are in turn related to reported concern. Several socioeconomic characteristics of individuals are shown to be useful in explaining the determinants of concern and perceptions of helplessness among respondents. As other cities face climate change-related challenges, the empirical findings, based upon attitudes from an alert urban population, are informative to policy design.

    As the Copenhagen Accord indicates, most of the international community agrees that global mean temperature should not be allowed to rise more than two degrees Celsius above preindustrial levels to avoid unacceptable damages from climate change. The scientific evidence distilled in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change and recent reports by the US National Academies shows that this can only be achieved by vast reductions of greenhouse gas emissions. Still, international cooperation on greenhouse gas emissions reductions suffers from incentives to free-ride and to renegotiate agreements in case of noncompliance, and the same is true for other so-called “public good games.” Using game theory, we show how one might overcome these problems with a simple dynamic strategy of linear compensation when the parameters of the problem fulfill some general conditions and players can be considered to be sufficiently rational. The proposed strategy redistributes liabilities according to past compliance levels in a proportionate and timely way. It can be used to implement any given allocation of target contributions, and we prove that it has several strong stability properties. PMID:21903930

    Punishment of non-cooperators-free riders-can lead to high cooperation in public goods games (PGG). However, second-order free riders, who do not pay punishment costs, reduce the effectiveness of punishment. Here we introduce a "leader support system," in which one group leader can freely punish group followers using capital pooled through the support of group followers. In our experiment, participants engage in three stages repeatedly: a PGG stage in which followers decide to cooperate for their group; a support stage in which followers decide whether to support the leader; and a punishment stage in which the leader can punish any follower. We compare a support-present condition with a no-support condition, in which there is an external source for the leader's punishment. The results show that punishment occurs more frequently in the support-present condition than the no-support condition. Within the former, both higher cooperation and higher support for a leader are achieved under linkage-type leaders-who punish both non-cooperators and non-supporters. In addition, linkage-type leaders themselves earn higher profits than other leader types because they withdraw more support. This means that leaders who effectively punish followers could increase their own benefits and the second-order free rider problem would be solved.

    Whether costly punishment encourages cooperation is one of the principal questions in studies on the evolution of cooperation and social sciences. In society, punishment helps deter people from flouting rules in institutions. Specifically, graduated punishment is a design principle for long-enduring common-pool resource institutions. In this study, we investigate whether graduated punishment can promote a higher cooperation level when each individual plays the public goods game and has the opportunity to punish others whose cooperation levels fall below the punisher's threshold. We then examine how spatial structure affects evolutionary dynamics when each individual dies inversely proportional to the game score resulting from the social interaction and another player is randomly chosen from the population to produce offspring to fill the empty site created after a player's death. Our evolutionary simulation outcomes demonstrate that stricter punishment promotes increased cooperation more than graduated punishment in a spatially structured population, whereas graduated punishment increases cooperation more than strict punishment when players interact with randomly chosen opponents from the population. The mathematical analysis also supports the results.

    Schizophrenia is generally characterized by various positive and negative symptoms that are accompanied by significant social dysfunction. Various researchers investigated the functional impairments in schizophrenia including impaired theory of mind (TOM), poor integration of affective and cognitive information, and malfunctioning of adaptive and strategic learning process. However, most of the studies were limited to simplified cognitive tests or computerized choice games that exclude real social interaction. The aim of the current study was to investigate human strategies based on the incentives and particularly the cognitive and emotional motivations of free riding. We examined the decision patterns of 41 healthy subjects (HSs) and 37 schizophrenia patients (SZ) during the public goods game (PGG), one of the games simulating human cooperation and free riding in group interactions. Strategic decision processes during the iterative binary PGG were assessed in terms of cognitive understanding, loss sensitivity, and TOM. We found that greed and loss sensitivity both motivated free-riding behavior in the HS, but that they were more vulnerable to greedy incentives than to possible loss. More significantly, the SZ clearly displayed a lower prevalence of free riding and distinct decision patterns from HS. Nonstrategic and unexpectedly low free ridings in the SZ likely arise from poor integration of cognitive and affective information. We suggest that loss sensitivity and TOM as well as cognitive understanding are involved in regulation of the free riding and cooperative behavior.

    The present study utilises social representations theory to explore common sense conceptualisations of global warming risk using an in-depth, qualitative methodology. Fifty-six members of a British, London-based 2008 public were initially asked to draw or write four spontaneous "first thoughts or feelings" about global warming. These were then explored via an open-ended, exploratory interview. The analysis revealed that first thoughts, either drawn or written, often mirrored the images used by the British press to depict global warming visually. Thus in terms of media framings, it was their visual rather than their textual content that was spontaneously available for their audiences. Furthermore, an in-depth exploration of interview data revealed that global warming was structured around three themata: self/other, natural/unnatural and certainty/uncertainty, reflecting the complex and often contradictory nature of common sense thinking in relation to risk issues.

    Decision-makers in both public and private organisations depend on accurate data and scientific understanding to adequately address climate change and the impact of extreme events. The financial impacts of catastrophes on populations and infrastructure can be offset through effective risk transfer mechanisms, structured to reflect the specific perils and levels of exposure to be covered. Optimal strategies depend on the likely socio-econonomic impact, the institutional framework, the overall objectives of the covers placed and the level of both the frequency and severity of loss potential expected. The diversity of approaches across different countries has been documented by the Spanish "Consorcio de Compensación de Seguros". We discuss why international public/private partnerships are necessary for addressing the risk of natural catastrophes. International initiatives such as the Global Earthquake Model (GEM) and the World Forum of Catastrophe Programmes (WFCP) can provide effective guidelines for constructing natural catastrophe schemes. The World Bank has been instrumental in the creation of many of the existing schemes such as the Turkish Catastrophe Insurance Pool, the Caribbean Catastrophe Risk Insurance Facility and the Mongolian Index-Based Livestock Insurance Program. We review existing schemes and report on best practice in relation to providing protection against natural catastrophe perils. The suitability of catastrophe modelling approaches to support schemes across the world are discussed and we identify opportunities to improve risk assessment for such schemes through transparent frameworks for quantifying, pricing, sharing and financing catastrophe risk on a local and global basis.

    Advances in biotechnology continue to drive the development of a wide range of insect-protected, herbicide-tolerant, stress-tolerant, and nutritionally enhanced genetically modified (GM) crops, yet societal and public policy considerations may slow their commercialization. Such restrictions may disproportionately affect developing countries, as well as smaller entrepreneurial and public sector initiatives. The 2014 IUPAC International Congress of Pesticide Chemistry (San Francisco, CA, USA; August 2014) included a symposium on "Challenges Associated with Global Adoption of Agricultural Biotechnology" to review current obstacles in promoting GM crops. Challenges identified by symposium presenters included (i) poor public understanding of GM technology and the need for enhanced communication strategies, (ii) nonharmonized and prescriptive regulatory requirements, and (iii) limited experience with regulations and product development within some public sector programs. The need for holistic resistance management programs to enable the most effective use of insect-protected crops was also a point of emphasis. This paper provides details on the symposium discussion and provides background information that can be used in support of further adoption of beneficial GM crops. Overall, it emphasizes that global adoption of modern agricultural biotechnology has not only provided benefits to growers and consumers but has great potential to provide solutions to an increasing global population and diminishing agricultural land. This potential will be realized by continued scientific innovation, harmonized regulatory systems, and broader communication of the benefits of the high-yielding, disease-resistant, and nutritionally enhanced crops attainable through modern biotechnology.

    2007-03-01

    Public policy decisions in both the social and economic spheres have enormous impact on global public health. As a result of this, and of the skewed global distribution of power and resources, health impact assessment (HIA) potentially has a key role to play in foreign policy-making and global public policy-making. Governments, multilateral bodies and transnational corporations need to be held to account for the health impacts of their policies and practices. One route towards achieving this objective involves the inclusion of human rights assessments within HIA. International commitments to human rights instruments and standards can be used as a global auditing tool. Methodological issues may limit the effectiveness of HIA in promoting health equity. These issues include the use of procedures that favour those holding power in the policy process or the use of procedures that fail to apply values of equity and participation. The identification and production of evidence that includes the interests of less powerful groups is a priority for HIA and would be furthered if a human rights-based method of HIA were developed. Because HIA considers all types of policies and examines all potential determinants of health, it can play a part when foreign policy is developed and global decisions are made to treat people as rights holders. Since the human right to health is shaped by the determinants of health, developing links between the right to health assessment (that is, an assessment of the impact of policies on the right to health) and HIA--as recently proposed by the United Nations Special Rapporteur on the right to health--could strengthen the development of foreign policy and global decisions. Such links should be pursued and applied to the development of foreign policy and to the operation of multilateral bodies.

However, this convergence (and the R&D underpinning it) will first require an even more fundamental convergence of the different worlds of public health and innovation, where a largely historical gap between global health experts and innovation experts is hindering achievement of the grand convergence in health.

    Exposure to indoor air pollution (IAP) from the burning of solid fuels for cooking, heating, and lighting accounts for a significant portion of the global burden of death and disease, and disproportionately affects women and children in developing regions. Clean cookstove campaigns recently received more attention and investment, but their successes might hinge on greater integration of the public health community with a variety of other disciplines. To help guide public health research in alleviating this important global environmental health burden, we synthesized previous research on IAP in developing countries, summarized successes and challenges of previous cookstove implementation programs, and provided key research and implementation needs from structured discussions at a recent symposium.

    2002-01-01

    This study is a theoretical as well as empirical exploration of the power and cultural differentials that mark and construct various intersecting discourses, specifically media discourse, on global AIDS/HIV. It applies the language and concepts of public relations to understand how the press coverage of the pandemic is associated with the variables that impact the newsmaking process as well as the public and policy implications of macro news frames generated over time. Theoretical work in the areas of agenda setting and news framing also instruct the conceptual framework of this analysis. Narrative analysis is used as a methodology to qualitatively analyze three pools of accounts-from people either living with AIDS/HIV, involved in AIDS/HIV work, or discursively engaged in the media construction of the pandemic; from transnational wire service journalists who cover the issue at global and regional levels; and policy shapers and communicators who are active at the global level. These three communities of respondents represent important stakeholders in the AIDS/HIV issue. The findings are analyzed from a public relations standpoint. Perhaps the most important finding of this study is that the public relations approaches used to address AIDS/HIV related issues need to be grounded in context-specific research and communicative practices that bring out the lived realities of AIDS/HIV at grassroots levels. The findings also posit that those situated at critical junctions between various stakeholders need to cultivate a finely balanced understanding of the etic and emic intersections and subjectivities of global/local AIDS/HIV.

    Climate change will have significant impacts on human health, and urban populations are expected to be highly sensitive. The health risks from climate change in cities are compounded by rapid urbanization, high population density, and climate-sensitive built environments. Local governments are positioned to protect populations from climate health risks, but it is unclear whether municipalities are producing climate-adaptive policies. In this article, we develop and apply systematic methods to assess the state of public health adaptation in 401 urban areas globally with more than 1 million people, creating the first global baseline for urban public health adaptation. We find that only 10% of the sampled urban areas report any public health adaptation initiatives. The initiatives identified most frequently address risks posed by extreme weather events and involve direct changes in management or behavior rather than capacity building, research, or long-term investments in infrastructure. Based on our characterization of the current urban health adaptation landscape, we identify several gaps: limited evidence of reporting of institutional adaptation at the municipal level in urban areas in the Global South; lack of information-based adaptation initiatives; limited focus on initiatives addressing infectious disease risks; and absence of monitoring, reporting, and evaluation.

    Since global warming and ozone deletion would occur over a long period of time, their adverse effects on public health may not be reversible. Therefore, more research is needed now to understand the complex and interacting issues of climate change and human health. Policy makers need to recognize the seriousness of the problem and, thus, the importance of increasing the level of funding for research and public education concerning health effects of climate change. Today, however, human influences are exerting major impacts on the environment and these influences are rebounding negatively upon them. Future climate change, including global warming, is real and unavoidable. Unfortunately, man has no assurances of the rate, the degree, the direction or the site of any specific change in climate. However, man may infer from past experiences with unexpected and acute episodes of local or regional warming that public health emergencies are likely to arise. Climate changes, in part, are driven by human influence and it will take several decades before their impacts on human health can be appreciated fully. Global climate change is likely to alter radically the distribution as well as the incidence of human illness. Exactly how and where these illnesses may appear is unpredictable. However, anticipating and preparing for the eventuality of these health threats would be both wise and prudent behavior.

    The proliferation of public-private partnerships is rapidly reconfiguring the international health landscape. This article (part I of two on the subject) traces the changing nature of partnership, and discusses the definitional and conceptual ambiguities surrounding the term. After defining global public-private partnerships (GPPPs) for health development, we analyse the factors which have led to the convergence of public and private actors and discuss the consequences of the trend toward partnership between UN agencies (including the World Bank) and commercial entities in the health sector. Generic factors such as globalization and disillusionment with the UN, and factors specific to the health sector, such as market failure in product development for orphan diseases, are examined. Reviewed are the interests, policies, practices and concerns of the UN, the private-for-profit sector, bilateral organizations, and governments of low-income countries with respect to public-private partnership. While GPPPs bring much needed resources to problems of international health, we highlight concerns regarding this new organizational format. Part II, which will be published in the May issue of the Bulletin, presents a conceptual framework for analysing health GPPPs and explores the issues raised. PMID:10885184

    The Olympic Games are increasingly used by non-governmental organizations to demand transnational forms of accountability from public authorities. This article assesses the effectiveness of transnational public opinion surrounding the Beijing 2008 Olympics, when the pressure of Western public opinion was exerted upon the government of the world's most populous non-Western nation to improve its human rights record. Utilizing the concepts of 'imagined global community' and 'transnational public sphere', it finds that the Olympic Games had helped to call into existence a transnational public that ran up against the obstacle posed by the incomplete formation of supra-national forms of governance. The International Olympic Committee, a non-governmental organization, was a weak substitute. Because of the strong desire of Chinese people to take part in transnational deliberations, the article concludes with optimism about the potential of transnational public spheres that include Chinese people to develop toward more effective forms of transnational governance. But the IOC must strengthen the voice of its non-Western members, and Western interlocutors, including the media, must accept their share of the responsibility for creating the conditions for egalitarian dialogue.

    There is great uncertainty due to challenges of escalating population growth and climate change. Public perception that diverges from the scientific community may decrease the effectiveness of scientific inquiry and innovation as tools to solve these challenges. The objective of this study was to identify the factors associated with the divergence of public opinion from scientific consensus regarding the safety of genetically modified (GM) foods and human involvement in global warming (GW). Results indicate that the effects of knowledge on public opinion are complex and non-uniform across types of knowledge (i.e., perceived and actual) or issues. Political affiliation affects agreement with science; Democrats were more likely to agree that GM food is safe and human actions cause GW. Respondents who had relatively higher cognitive function or held illusionary correlations about GM food or GW were more likely to have an opinion that differed from the scientific community.

    In recent years a succession of health emergencies connected with the threat of new, possibly global, infectious diseases has stimulated the attention of the mass media, the scientific community, and international public opinion, setting a tough test for the institutions whose job is to manage the risks. On the basis of experience in the fields of AIDS, BSE, SARS and bird flu, this study discusses the strong and weak points of governance procedures for health risks. In particular, the paper illustrates how risk management can be improved by adopting practices and procedures which actively involve the public in dealing with the emergency, by taking a transparent and accessible approach to communication with the public (including the provision of information about the risks) and by fostering the unrestricted exchange of scientific knowledge among researchers. Lastly, the text shows how the analysis of these themes provides starting points for understanding the crisis in the current relationship between science and society.

  11. Examining the Gap between Science and Public Opinion about Genetically Modified Food and Global Warming.

    There is great uncertainty due to challenges of escalating population growth and climate change. Public perception that diverges from the scientific community may decrease the effectiveness of scientific inquiry and innovation as tools to solve these challenges. The objective of this study was to identify the factors associated with the divergence of public opinion from scientific consensus regarding the safety of genetically modified (GM) foods and human involvement in global warming (GW). Results indicate that the effects of knowledge on public opinion are complex and non-uniform across types of knowledge (i.e., perceived and actual) or issues. Political affiliation affects agreement with science; Democrats were more likely to agree that GM food is safe and human actions cause GW. Respondents who had relatively higher cognitive function or held illusionary correlations about GM food or GW were more likely to have an opinion that differed from the scientific community.

  12. Individual differences in behavioural inhibition explain free riding in public good games when punishment is expected but not implemented

    2013-01-01

    Background The literature on social dilemmas and punishment focuses on the behaviour of the punisher. However, to fully explain the effect of punishment on cooperation, it is important to understand the psychological mechanisms influencing the behaviour of those who expect to be punished. This paper examines whether the expectation of punishment, rather than the implementation of punishment is sufficient to prevent individuals from free riding. Individual differences in the punishment sensitivity have been linked to both threat responses (flight, fight, fear system, or the FFFS) and to the response to the uncertainty of punishment (BIS-anxiety).The paper, therefore, examines if individual differences in BIS-anxiety and FFFS can explain some of the variability in free riding in the face of implemented and non-implemented punishment. Methods Participants took part in a series of one-shot Public Goods Games (PGGs) facing two punishment conditions (implemented and non-implemented) and two standard non-punishment PGGs. The punishment was implemented as a centralized authority punishment (i.e., if one participant contributed less than their group members, they were automatically fined). Individual contribution levels and presence/absence of zero contributions indexed free riding. Individual differences in behavioural inhibition were assessed. Results Individuals contributed more under the threat of punishment (both implemented and non-implemented). However, individuals contributed less when the punishment was not implemented compared to when it was. Those scoring high in BIS-anxiety contributed more when the punishment expectations were not implemented. This effect was not observed for FFFS. Conclusion Supporting previous research, punishment had a powerful effect in increasing contribution levels in the PGGs. However, when expected punishment was not implemented, individual differences in punishment sensitivity, specifically in BIS-anxiety, were related to fewer

  13. Eyes wide open: an essay on developing an engaged awareness in global medicine and public health

    PubMed Central

    2014-01-01

    Background There is a growing understanding of the role social determinants such as poverty, gender discrimination, racial prejudice, and economic inequality play on health and illness. While these determinants and effects may be challenging to identify in parts of high-income countries, they are patently obvious in many other areas of the world. How we react to these determinants and effects depends on what historical, cultural, ideological, and psychological characteristics we bring to our encounters with inequity, as well as how our feelings and thoughts inform our values and actions. Discussion To address these issues, we share a series of questions we have asked ourselves¿United States¿ citizens with experience living and working in Central America¿in relation to our encounters with inequity. We offer a conceptual framework for contemplating responses in hopes of promoting among educators and practitioners in medicine and public health an engaged awareness of how our every day work either perpetuates or breaks down barriers of social difference. We review key moments in our own experiences as global health practitioners to provide context for these questions. Summary Introspective reflection can help professionals in global medicine and public health recognize the dynamic roles that they play in the world. Such reflection can bring us closer to appreciating the forces that have worked both for and in opposition to global health, human rights, and well-being. It can help us recognize how place, time, environment, and context form the social determination of health. It is from this holistic perspective of social relations that we can work to effect fair, equitable, and protective environments as they relate to global medicine and public health. PMID:25346040

    2008-01-01

    Background The global tobacco epidemic claims 5 million lives each year, facilitated by the ability of transnational tobacco companies to delay or thwart meaningful tobacco control worldwide. A series of cross-company tobacco industry "issues management organizations" has played an important role in coordinating and implementing common strategies to defeat tobacco control efforts at international, national, and regional levels. This study examines the development and enumerates the activities of these organizations and explores the implications of continuing industry cooperation for global public health. Methods Using a snowball sampling strategy, we collected documentary data from tobacco industry documents archives and assembled them into a chronologically organized case study. Results The International Committee on Smoking Issues (ICOSI) was formed in 1977 by seven tobacco company chief executives to create common anti-tobacco control strategies and build a global network of regional and national manufacturing associations. The organization's name subsequently changed to INFOTAB. The multinational companies built the organization rapidly: by 1984, it had 69 members operating in 57 countries. INFOTAB material, including position papers and "action kits" helped members challenge local tobacco control measures and maintain tobacco-friendly environments. In 1992 INFOTAB was replaced by two smaller organizations. The Tobacco Documentation Centre, which continues to operate, distributes smoking-related information and industry argumentation to members, some produced by cross-company committees. Agro-Tobacco Services, and now Hallmark Marketing Services, assists the INFOTAB-backed and industry supported International Tobacco Growers Association in advancing claims regarding the economic importance of tobacco in developing nations. Conclusion The massive scale and scope of this industry effort illustrate how corporate interests, when threatened by the globalization of

    Introduction Peace and stability in Eastern Europe is now at a crossroads with the rapidly deteriorating foreign policy crisis continuing to unfold in the Ukraine. However, largely overlooked in the context of other foreign policy and diplomatic priorities are the serious public health consequences for the region following the annexation of Crimea and the subsequent decision to ban opioid substitution therapy in the disputed territory. Discussion On 1 May 2014, the Republic of Crimea officially announced it would end access to opioid substitution therapy, an essential harm reduction tool recognized by international organizations and virtually all other European countries. The policy development marks a critical reversal in the region’s fight against its growing HIV epidemic and also threatens years of public health gains aimed at providing evidence-based and integrated treatment approaches to combat drug dependence and HIV. Beyond these risks, the Ukrainian conflict could also negatively impact control of other infectious diseases that are converging with HIV and injection drug use, such as multidrug-resistant tuberculosis and hepatitis C virus. The continuing conflict is also likely to have a significant negative impact on Ukraine’s fragile public health system leading to even worse population health outcomes than currently experienced by the country. Conclusions In response to this crisis, the application of global health diplomacy principles represents a possible route of advocacy to ensure that HIV prevention, humane treatment of substance using populations, and improving public health outcomes in the region are pursued among concerned international stakeholders. In order to be effective, global health diplomacy efforts must be coordinated and advocated in all forms of diplomatic engagement, including at the core, multistakeholder and informal levels and through existing channels such as the different human rights bodies of the United Nations as well as

  17. Bio-terrorism, human security and public health: can international law bring them together in an age of globalization?

    Bio-terrorism, the use of a microorganism with the deliberate intent of causing infection, before and since the anthrax attacks in the United States in October 2001, has emerged as a real medical and public health threat. The link between bio-terrorism, human security and public health raises complex questions on the normative trajectories of international law, the mandates of international organizations, and global health governance. In May 2001, the World Health Assembly of the World Health Organization (WHO) passed a resolution entitled "Global Health Security: Epidemic Alert and Response" which inter alia, urged WHO member states to participate actively in the verification and validation of surveillance data and information concerning health emergencies of international concern. This article explores the links between bio-terrorism, human security and public health, and investigates the effectiveness of international legal mechanisms that link them in an age of globalization of public health. The article explores the interaction of WHO's 'soft-law' approaches to global health security, and the 'moribund' negotiations of the verification and monitoring protocol to the Biological Weapons Convention 1972. Can international law link bio-terrorism, public health and human security? Does the WHO collaborate with other international organizations within and outside the United Nations system to develop effective legal and governance approaches to bio-terrorism and global health security? The article concludes that the globalization of public health threats like bio-terrorism requires globalized legal approaches.

    In June 2015 the scientific academies "Leopoldina" and "acatech" and the union of the German academies of sciences and humanities published a statement on public and global health in Germany. The statement contains many valuable albeit generic and well-known recommendations. The few specific recommendations focus on centralizing research while weakening the role of universities and on the relative increase of research on public health genomics. These recommendations are not based on empirical or theoretical analyses and risk subverting successful developments of the recent past. To actually strengthen public and global health in Germany the existing institutions need to be backed up while designated funding of public and global health needs to be extended.

  1. Imperial or postcolonial governance? Dissecting the genealogy of a global public health strategy.

    PubMed

    Brown, Tim; Bell, Morag

    2008-11-01

    During the last decades of the 20th century it became increasingly apparent that the inter-relationship between globalisation and health is extremely complex. This complexity is highlighted in debates surrounding the re-emergence of infectious diseases, where it is recognised that the processes of globalisation have combined to create the conditions where once localised, microbial hazards have come to pose a threat to many western nations. By contrast, in an emerging literature relating to the epidemic of non-communicable diseases, and reflected in the WHO 'Global strategy on diet, physical activity and health', it is the so-called 'western lifestyle' that has been cast as the main threat to a population's health. This paper explores critically global responses to this development. Building on our interest in questions of governance and the ethical management of the healthy body, we examine whether the global strategy, in seeking to contain the influence of a 'western lifestyle', also promotes contemporary 'western-inspired' approaches to public health practices. The paper indicates that a partial reading of the WHO strategy suggests that certain countries, especially those outside the West, are being captured or 'enframed' by the integrative ambitions of a western 'imperial' vision of global health. However, when interpreted critically through a postcolonial lens, we argue that 'integration' is more complex, and that the subtle and dynamic relations of power that exist between countries of the West/non-West, are exposed.

    2007-11-01

    Global public health surveillance is critical for the identification and prevention of emerging and reemerging infectious diseases. The World Health Organization recently released revised International Health Regulations (IHR) that serve as global legislation and provide guidelines for surveillance systems. The IHR aim to identify and prevent spread of these infectious diseases; however, there are some practical challenges that limit the usability of these regulations. IHR requires Member States to build necessary infrastructure for global surveillance, which may not be possible in underdeveloped countries. A large degree of freedom is given to each individual government and therefore different levels of reporting are common, with substantial emphasis on passive reporting. The IHR need to be enforceable and enforced without impinging on government autonomy or human rights. Unstable governments and developing countries require increased assistance in setting up and maintaining surveillance systems. This article addresses some challenges and potential solutions to the ability of national governments to adhere to the global health surveillance requirements detailed in the IHR. The authors review some practical challenges such as inadequate surveillance and reporting infrastructure, and legal enforcement and maintenance of individual human rights.

    2014-01-01

    The procedures for collecting voluntarily and freely donated umbilical cord blood (UCB) units and processing them for use in transplants are extremely costly, and the capital flows thus generated form part of an increasingly pervasive global bioeconomy. To place the issue in perspective, this article first examines the different types of UCB biobank, the organization of international registries of public UCB biobanks, the optimal size of national inventories, and the possibility of obtaining commercial products from donated units. The fees generally applied for the acquisition of UCB units for transplantation are then discussed, and some considerations are proposed regarding the social and ethical implications raised by the international network for the importation and exportation of UCB, with a particular emphasis on the globalized bioeconomy of UCB and its commerciality or lack thereof.

    There is increased global recognition of attention deficit hyperactivity disorder (ADHD) as a serious medical condition with long-term consequences. Although originally conceived of as a childhood disorder, ADHD is being increasingly recognized in adults. Individual geographic regions may have specific interests and objectives for the study of ADHD. A systematic review of long-term outcomes (LTOs) in ADHD was conducted to evaluate research on ADHD LTOs on a global scale. Studies that were at least 2 years in duration were examined. A total of 351 studies were identified in the final analysis. We identified nine outcomes of interest and classified studies by specific geographical regions, age groups studied and study design by region and over time. Published studies of LTOs in ADHD have increased in all geographical regions over the past three decades, with a peak number of 42 publications in 2008. This rise in publications on ADHD LTOs may reflect a rise in global interest and recognition of consequences and impairment associated with ADHD. Although many world regions have published on ADHD LTOs, the majority of studies have emerged from the US and Canada, followed by Europe. While investigators in the US and Canada were predominantly interested in drug addiction as a LTO, European researchers were more interested in antisocial behavior, and Eastern Asian investigators focused on both of these LTOs as well as self-esteem. Geographical differences in the focus of ADHD LTO studies may reflect regional variations in cultural values. Proportionally fewer prospective longitudinal studies and proportionally more retrospective and cross-sectional studies have been published in more recent decades. Finally, more studies focusing on ADHD in adolescents and adults have been conducted in recent years, and particularly adolescents in Eastern Asia. These changes in basic study design may reflect an increase in the recognition that ADHD is a lifetime chronic disorder. This

    2013-10-01

    Unconventional drilling for natural gas by means of high volume horizontal hydraulic fracturing (fracking) is an important global public health issue. Given that no sound epidemiologic study has been done to assess the extent of exposure-related adverse health effects among populations living in areas where natural gas extraction is going on, it is imperative that research be conducted to quantify the potential risks to the environment and to human health not just in the short-term, but over a longer time period since many diseases (i.e., cancers) appear years after exposure. It should not be concluded that an absence of data implies that no harm is being done.

    2015-06-01

    This paper examines the challenges facing the Nigerian government toward the implementation of global public health priories. The Nigerian government recognizes the need to implement these priorities by putting in place the necessary policy framework, but political instability, poor infrastructural development and inadequate funding have remained barriers toward the achievement of success in implementing these priorities. The rest of the paper elucidates the fact that despite leadership and influence from the World Health Organization and other United Nations agencies, and some responses from the Nigerian government, tackling these public health problems requires much more fundamental reform to primary health services and a reduction in poverty. Although the government has shown enough political will to tackle these problems, it is expected that a better result will be achieved through injecting more funds into the Nigerian health sector, and deploying astute health administrators to manage the sector rather than pure health professionals without managerial acumen.

    2016-01-01

    Summary: Water quality issues in Rio have been widely publicized because of the 2016 Olympics. Recent concerns about polluted waters that athletes may be exposed to highlights the conditions that more than a billion people globally are exposed to daily. Despite these unhealthy conditions, much is unknown about the risks and exposure pathways associated with bathing in or drinking untreated or partially treated sewage. Beyond acute illness, we are learning more about the chronic sequelae that arise from repeated exposure to pathogens found in sewage. Additionally, we do not know enough about how to measure water quality, especially in developing countries. A consequence of these knowledge gaps is that data from developed countries are used to guide public health approaches in low- and middle-income settings. More data that are locally specific are needed to inform guidelines for improving sanitation and water quality in Rio and other cities in developing countries. PMID:27689546

    2010-05-30

    The landscape of foodborne infections is in flux. New pathogens emerge, established pathogens may acquire new characteristics and appear in unexpected food vehicles, while many existing problems remain unsolved. Consumers want more fresh foods year round, populations age and migrate, and the technologies and trade practices that produce foods change. Protecting the public health and minimizing the burden of foodborne illness mean expecting the unexpected, and being prepared to understand it when it occurs, so that prevention can be improved. Public health surveillance is also constantly evolving, as new diseases emerge and are judged worthy of notification, as new diagnostic tests change the ease and specificity of routine diagnosis and as social interest in particular issues waxes and wanes. Accurate health information, including reliable estimates of the burden of foodborne disease, can improve foodborne disease prevention, foster global health security, promote economic growth and development and strengthen evidence-based policy making.

    Emergency medicine (EM) is a global discipline that provides secondary disease prevention and is also a tool for primary prevention. It is a horizontally integrated system of emergency care consisting of access to EM care; provision of EM care in the community and during transportation of patients; and provision of care at the receiving facility or hospital emergency department. EM can offer many tools to improve public health. These tools include primary disease prevention; interventions for addressing substance abuse and interpersonal violence; education about safety practices; epidemiological surveillance; enrolment of patients in clinical research trials focusing on acute interventions; education and clinical training of health-care providers; and participation in local and regional responses to natural and man-made disasters. Public health advocates and health policy-makers can benefit from the opportunities of EM and can help overcome its challenges. Advocating the establishment and recognition of the specialty of EM worldwide can result in benefits for health-care education, help in incorporating the full scope of EM care into the system of public health, and expand the capabilities of EM for primary and secondary prevention for the benefit of the health of the public.

    PubMed

    Sastry, Shaunak; Dutta, Mohan J

    2012-01-01

    Drawing upon a postcolonial lens, this project looks at how meanings of HIV/AIDS are discursively constructed within the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), which was launched in 2003 under the presidency of George W. Bush and has been heralded as the largest global public health intervention program in history. Building on existing literature that theorizes the interrelationships of public health and national security, global surveillance, and transnational hegemony, the postcolonial theoretical standpoint interrogates how such meanings are constructed within PEPFAR. A postcolonial deconstruction of the 2009 PEPFAR report to the Congress revealed three meanings of HIV/AIDS that were discursively constructed in such policy documents: (a) the "Third World" as a site of intervention, (b) U.S. altruism as "lifting" the burden of the soul, and (c) AIDS, economics, and security. The themes put forth the linkages among the symbolic representations in neocolonial configurations and the politics of material disparities across the globe, thus issuing a call for the creation of participatory and dialogic spaces for engaging subaltern voices that are typically treated as targets of policy and intervention discourses.

  16. The global reproductive health market: U.S. media framings and public discourses about transnational surrogacy.

    PubMed

    Markens, Susan

    2012-06-01

    During the first decade of the 21st century a new "dramatic story" about the growing global surrogacy industry brought renewed attention to surrogacy as a social problem and a health policy issue. This paper asks: What cultural assumptions about gender, family and the global reproductive health market are revealed in current U.S. media coverage of and public discourses about surrogacy? From a qualitative analysis of prominent news accounts of surrogacy that were published in 2008, New York Times articles and blogs published on the topic between 2006 and 2010, and over 1000 online reader comments to these articles, I identify key frames used to discursively construct and debate the international surrogacy market. This study reveals the distinct contrast between the occasions when reproductive labor is rhetorically distanced from commodification processes and when it is linked to those processes. The findings contribute to intersectional analyses of assisted reproductive practices and women's health/bodies/gametes. In particular, this study's analysis of recent media framings of and public discourses about surrogacy across the globe serves as another illustration that national/classed/racialized bodies continue to be reproductively stratified via differently gendered discourses about women, motherhood and family.

    2005-01-01

    In a time of public scrutiny, it is paramount that Catholic health care organizations examine their commitments to their communities and effectively communicate community benefit activities to stakeholders-employees, physicians, patients, and the public. CHRISTUS Academy, a leadership development program at CHRISTUS Health, Irving, TX, conducted two studies regarding community benefit. The first researched community benefit practices at more than 20 highly respected, tax-exempt CHA- and VHA-member organizations, comparing them with the practices of about 40 publicly traded, for-profit organizations. The primary conclusion was that community benefit is not just about measuring the numbers-it is also about "telling the story." Unlike the for-profit organizations, tax-exempt health care organizations tend to struggle with adequately measuring and reporting their community contributions. In a second study, the academy surveyed CHRISTUS Health's employees and physicians regarding their knowledge of the system's commitment vis-à-vis identifying and meeting community needs. The vast majority said the system is important to the community and is actively involved in understanding and meeting the needs of the community. However, they also ranked the system lower in terms of working with other community organizations, being a leader in community health, and being known for sponsoring volunteer activities. These lower rankings indicate that the community benefit activities are not well publicized or known within the organization. Catholic health organizations must take an active approach in communicating their work to the public, the media, and each other. In doing so, they fulfill an integral part their mission.

    In response both to national pressures to reduce costs and improve health care access and outcomes and to local pressures to become a top-20 public research university, the University of Kentucky moved toward an integrated clinical enterprise, UK HealthCare, to create a common vision, shared goals, and an effective decision-making process. The leadership formed the vision and then embarked on a comprehensive and coordinated planning process that addressed financial, clinical, academic, and operational issues. The authors describe in depth the strategic planning process and specifically the definition of UK HealthCare's role in its medical marketplace. They began a rigorous process to assess and develop goals for the clinical programs and followed the progress of these programs through meetings driven by data and attended by the organization's senior leadership. They describe their approach to working with rural and community hospitals throughout central, eastern, and southern Kentucky to support the health care infrastructure of the state. They review the early successes of their strategic approach and describe the lessons they learned. The clinical successes have led to academic gains. The experience of UK HealthCare suggests that good business practices and good public policy are synergistic.

  19. Nanotechnology in global medicine and human biosecurity: private interests, policy dilemmas, and the calibration of public health law.

    This paper considers how best to approach dilemmas posed to global health and biosecurity policy by increasing advances in practical applications of nanotechnology. The type of nano-technology policy dilemmas discussed include: (1) expenditure of public funds, (2) public-funded research priorities, (3) public confidence in government and science and, finally, (4) public safety. The article examines the value in this context of a legal obligation that the development of relevant public health law be calibrated against less corporate-influenced norms issuing from bioethics and international human rights.

    In 1983 the World Health Assembly declared alcohol-related problems to be among the world's major health concerns. Since then, alcohol consumption has risen in developing countries, where it takes a heavy toll. Alcohol-related problems are at epidemic levels in the successor states of the Soviet Union and are responsible for 3.5% of disability-adjusted life years (DALYs) lost globally. Substantial evidence exists of the relationship between the levels and patterns of alcohol consumption on the one hand and the incidence of alcohol-related problems on the other. Over the past 20 years, research has demonstrated the effectiveness of public policies involving, for example, taxation and restrictions on alcohol availability, in reducing alcohol-related problems. In the wake of rapid economic globalization, many of these policies at national and subnational levels have been eroded, often with the support of international financial and development organizations. Development agencies and international trade agreements have treated alcohol as a normal commodity, overlooking the adverse consequences of its consumption on productivity and health. WHO is in a strong position to take the lead in developing a global alcohol policy aimed at reducing alcohol-related problems, providing scientific and statistical support, capacity-building, disseminating effective strategies and collaborating with other international organizations. Such leadership can play a significant part in diminishing the health and social problems associated with alcohol use. PMID:10885168

    In a relatively short interval for an emerging technology, nanotechnology has made a significant economic impact in numerous sectors including semiconductor manufacturing, catalysts, medicine, agriculture, and energy production. A part of the United States (US) government investment in basic research has been realized in the last two decades through the National Science Foundation (NSF), beginning with the nanoparticle research initiative in 1991 and continuing with support from the National Nanotechnology Initiative after fiscal year 2001. This paper has two main goals: (a) present a longitudinal analysis of the global nanotechnology development as reflected in the United States Patent and Trade Office (USPTO) patents and Web of Science (WoS) publications in nanoscale science and engineering (NSE) for the interval 1991-2012; and (b) identify the effect of basic research funded by NSF on both indicators. The interval has been separated into three parts for comparison purposes: 1991-2000, 2001-2010, and 2011-2012. The global trends of patents and scientific publications are presented. Bibliometric analysis, topic analysis, and citation network analysis methods are used to rank countries, institutions, technology subfields, and inventors contributing to nanotechnology development. We then, examined how these entities were affected by NSF funding and how they evolved over the past two decades. Results show that dedicated NSF funding used to support nanotechnology R&D was followed by an increased number of relevant patents and scientific publications, a greater diversity of technology topics, and a significant increase of citations. The NSF played important roles in the inventor community and served as a major contributor to numerous nanotechnology subfields.

    The objective was to analyze the proteomic composition of uterine flushes collected from beef heifers on day 7 after insemination. Estrus was synchronized in crossbred beef heifers by using a protocol with a controlled intravaginal drug releasing device. Heifers detected in standing estrus (within 24-48 h after removal of controlled intravaginal drug releasing device) were inseminated (estrus = day 0) with frozen-thawed semen from a single ejaculate of a bull with proven fertility. Heifers from which an embryo was recovered (after slaughter on day 7) were classified as either having a viable embryo (morula/blastocyst stage) or a degenerate embryo (arrested at the 2- to 16-cell stage). The overall recovery rate (viable and degenerate combined) was 64%. Global liquid chromatography coupled to tandem mass spectrometry proteomic analysis of the histotroph collected identified 40 high-confidence proteins present on day 7; 26 proteins in the viable group, 10 in the degenerate group, and 4 shared between both groups. Five proteins (platelet-activating factor acetylhydrolase IB subunit γ [PAFAH1B3], tubulin α-1D chain, tubulin β-4A chain, cytochrome C, and dihydropyrimidinase-related protein-2) were unique or more abundant in the histotroph collected from animals with a viable embryo, and 1 protein (S100-A4) was more abundant in the histotroph collected from animals with a degenerate embryo. Of interest, PAFAH1B3, detected only in histotroph from the group yielding viable embryos, belongs to the group of platelet-activating factors that are known to be important for the development of the pre-implantation embryo in other species. To our knowledge this is the first report of PAFAH1B3 in relation to bovine early embryonic development.

    Recent advancement of land-based mobile mapping enables rapid and cost-effective collection of highquality road related spatial information. Mobile Mapping Systems (MMS) can provide spatial information with subdecimeter accuracy in nominal operation environments. However, performance in challenging environments such as tunnels is not well characterized. The Norwegian Public Roads Administration (NPRA) manages the country's public road network and its infrastructure, a large segment of which is represented by road tunnels (there are about 1 000 road tunnels in Norway with a combined length of 800 km). In order to adopt mobile mapping technology for streamlining road network and infrastructure management and maintenance tasks, it is important to ensure that the technology is mature enough to meet existing requirements for object positioning accuracy in all types of environments, and provide homogeneous accuracy over the mapping perimeter. This paper presents results of a testing campaign performed within a project funded by the NPRA as a part of SMarter road traffic with Intelligent Transport Systems (ITS) (SMITS) program. The testing campaign objective was performance evaluation of high end commercial MMSs for inventory of public areas, focusing on Global Navigation Satellite System (GNSS) signal degraded environments.

  5. Celebrating the work of Gavin Mooney: inclusiveness and involvement in global and public health issues.

    2014-05-01

    This paper considers Gavin Mooney's contributions to the research literature on inclusiveness in global and public health issues. Much of his contribution in this area stems from engaging with Indigenous people, which cemented his conviction that it is important to recognise the heterogeneity of groups in society, especially in relation to cultural differences. He believed that in order to develop appropriate equitable and efficient health and related policies, the preferences of citizens should be elicited. While this could feed into very specific policy decisions, such as how to allocate available resources within a particular community, more generally, community preferences should determine the core values that underpin a health system. He proposed that these values be documented in a 'constitution' and serve as the basis on which policy-makers and health managers make decisions. Preference elicitation has value in itself, as procedural justice allows for self-determination and contributes to empowerment. Further, engagement by citizens in deliberative processes can overcome polarisation. Health systems themselves, if developed as social institutions, can influence the nature of society and contribute to greater unity. Mooney raised similar concerns about policies arising from mono-cultural global perspectives and argued that, whether at the national or global level, values for health systems should be based on community preferences. He particularly highlighted the unequal distribution of benefits of neoliberal globalisation as the cause of growing health and wealth inequalities globally. There is resonance between Mooney's views on these issues and some of the contributions to the post-2015 development agenda debates. While it is unlikely that we have reached a point where the stranglehold of neo-liberal governments on key global institutions will be broken, the current debates nevertheless present an important window of opportunity to struggle for shifts in

    This study evaluated primary care attributes of patient-centered care associated with the public perception of good quality in Brazil, Colombia, Mexico and El Salvador. We conducted a secondary data analysis of a Latin American survey on public perceptions and experiences with healthcare systems. The primary care attributes examined were access, coordination, provider-patient communication, provision of health-related information and emotional support. A double-weighted multiple Poisson regression with robust variance model was performed. The study included between 1500 and 1503 adults in each country. The results identified four significant gaps in the provision of primary care: not all respondents had a regular place of care or a regular primary care doctor (Brazil 35.7%, Colombia 28.4%, Mexico 22% and El Salvador 45.4%). The communication with the primary care clinic was difficult (Brazil 44.2%, Colombia 41.3%, Mexico 45.1% and El Salvador 56.7%). There was a lack of coordination of care (Brazil 78.4%, Colombia 52.3%, Mexico 48% and El Salvador 55.9%). Also, there was a lack of information about healthy diet (Brazil 21.7%, Colombia 32.9%, Mexico 16.9% and El Salvador 20.8%). The public's perception of good quality was variable (Brazil 67%, Colombia 71.1%, Mexico 79.6% and El Salvador 79.5%). The primary care attributes associated with the perception of good quality were a primary care provider 'who knows relevant information about a patient's medical history', 'solves most of the health problems', 'spends enough time with the patient', 'coordinates healthcare' and a 'primary care clinic that is easy to communicate with'. In conclusion, the public has a positive perception of the quality of primary care, although it has unfulfilled expectations; further efforts are necessary to improve the provision of patient-centered primary care services in these four Latin American countries.

  7. Partnering with law enforcement to deliver good public health: the experience of the HIV/AIDS Asia regional program

    2012-01-01

    In the South-East Asia region, the drug control and supply reduction agenda is of high political importance. A multitude of law enforcement agencies are engaged in this work. Nationwide campaigns such as the “Strike- Hard” campaign in China or the “war on drugs” in Thailand dominate the landscape. Viet Nam’s response to drug use has historically focused on deterrence through punishment and supply-side measures. This policy environment is further complicated by lack of evidence-based drug dependence treatment in several settings. The public health consequences of this approach have been extremely serious, with some of the highest documented prevalence of preventable blood-borne viral infections, including HIV, and hepatitis B and C. The wider socioeconomic consequences of this have been borne by families, communities and the governments themselves. The HIV/AIDS Asia Regional Program (HAARP) aims to stop the spread of HIV associated with drug use in South-East Asia and parts of southern China. HAARP works across five countries (Cambodia, China Burma, Laos, Viet Nam) chiefly through the Ministries of Health and Social Affairs, National Drug Control Agencies, and Public Security sectors, including prisons. HAARP has also engaged with UN agencies and a wide range of civil society organisations, including organisations of people who use drugs, to ensure their meaningful involvement in matters that directly affect them. We describe the experience of HAARP in implementing a large-scale harm reduction programme in the Sub-Mekong Region. HAARP chose to direct its efforts in three main areas: supporting an enabling environment for effective harm reduction policies, building core capacity among national health and law enforcement agencies, and supporting “universal access” goals by making effective, high-coverage services available to injecting drug users and their partners. The activities supported by HAARP are humble yet important steps. However, a much higher

    International population mobility is an underlying factor in the emergence of public health threats and risks that must be managed globally. These risks are often related, but not limited, to transmissible pathogens. Mobile populations can link zones of disease emergence to lowprevalence or nonendemic areas through rapid or high-volume international movements, or both. Against this background of human movement, other global processes such as economics, trade, transportation, environment and climate change, as well as civil security influence the health impacts of disease emergence. Concurrently, global information systems, together with regulatory frameworks for disease surveillance and reporting, affect organizational and public awareness of events of potential public health significance. International regulations directed at disease mitigation and control have not kept pace with the growing challenges associated with the volume, speed, diversity, and disparity of modern patterns of human movement. The thesis that human population mobility is itself a major determinant of global public health is supported in this article by review of the published literature from the perspective of determinants of health (such as genetics/biology, behavior, environment, and socioeconomics), population-based disease prevalence differences, existing national and international health policies and regulations, as well as inter-regional shifts in population demographics and health outcomes. This paper highlights some of the emerging threats and risks to public health, identifies gaps in existing frameworks to manage health issues associated with migration, and suggests changes in approach to population mobility, globalization, and public health. The proposed integrated approach includes a broad spectrum of stakeholders ranging from individual health-care providers to policy makers and international organizations that are primarily involved in global health management, or are influenced

    2017-02-04

    Ongoing failure by the international community to resolve the Syrian conflict has led to destruction of critical infrastructure. This includes the collapse of the Syrian health system, leaving millions of internally displaced persons (IDPs) in urgent need of healthcare services. As the conflict intensifies, IDP populations are suffering from infectious and non-communicable disease risks, poor maternal and child health outcomes, trauma, and mental health issues, while healthcare workers continually exit the country. Healthcare workers who remain face significant challenges, including systematic attacks on healthcare facilities and conditions that severely inhibit healthcare delivery and assistance. Within this conflict-driven public health crisis, the most susceptible population is arguably the IDP. Though the fundamental 'right to health' is a recognised international legal principle, its application is inadequate due to limited recognition by the UN Security Council and stymied global governance by the broader international community. These factors have also negatively impacted other vulnerable groups other than IDPs, such as refugees and ethnic minorities, who may or may not be displaced. Hence, this article reviews the current Syrian conflict, assesses challenges with local and global governance for IDPs, and explores potential governance solutions needed to address this health and humanitarian crisis.

    Cryptosporidium spp. are coccidians, oocysts-forming apicomplexan protozoa, which complete their life cycle both in humans and animals, through zoonotic and anthroponotic transmission, causing cryptosporidiosis. The global burden of this disease is still underascertained, due to a conundrum transmission modality, only partially unveiled, and on a plethora of detection systems still inadequate or only partially applied for worldwide surveillance. In children, cryptosporidiosis encumber is even less recorded and often misidentified due to physiological reasons such as early-age unpaired immunological response. Furthermore, malnutrition in underdeveloped countries or clinical underestimation of protozoan etiology in developed countries contribute to the underestimation of the worldwide burden. Principal key indicators of the parasite distribution were associated to environmental (e.g., geographic and temporal clusters, etc.) and host determinants of the infection (e.g., age, immunological status, travels, community behaviours). The distribution was geographically mapped to provide an updated picture of the global parasite ecosystems. The present paper aims to provide, by a critical analysis of existing literature, a link between observational epidemiological records and new insights on public health, and diagnostic and clinical impact of cryptosporidiosis.

  12. From the field side of the binoculars: a different view on global public health surveillance.

    PubMed

    Calain, Philippe

    2007-01-01

    It is generally assumed by the donor community that the targeted funding of global, regional or cross-border surveillance programmes is an efficient way to support resource-poor countries in developing their own national public health surveillance infrastructure, to encourage national authorities to share outbreak intelligence, and ultimately to ensure compliance of World Health Organization (WHO) Member States with the revised (2005) International Health Regulations. At country level, a number of factors and constraints appear to contradict this view. Global or regional surveillance initiatives, including syndromic surveillance and rumour surveillance projects, have been conceived in neglect of fragile health systems, from which they extract scarce human resources. In contradiction with a rightful stance promoting 'integrated surveillance' by WHO, the nurturing of donor-driven, poorly coordinated and redundant surveillance networks generally adds further fragmentation to national health priorities set up by developing countries. In their current categorical format, ignoring the overwhelming deficits in governance and health care capacity, global surveillance strategies seem bound to benefit mainly the most industrially developed nations through the provision of early warning information or scientific data. In lower-income countries, a focus of resources on strengthening the health system first would ultimately be a more efficient way to achieve proper detection and response to outbreaks at national or sub-national level. As documented in several pilot initiatives at sub-national level (India, South Africa, Tuvalu and Cambodia), the empowerment of frontline health workers and communities is a key element for an efficient surveillance system. Such simple measures centred on human resources and community values appear to be more beneficial than massive and conditional monetary inputs.

    During the last decade, a great deal of news media attention has focused on informing the American public about scientific findings on global warming (GW). Has learning this sort of information led the American public to become more concerned about GW? Using data from two surveys of nationally representative samples of American adults, this article shows that the relation between self-reported knowledge and concern about GW is more complex than what previous research has suggested. Among people who trust scientists to provide reliable information about the environment and among Democrats and Independents, increased knowledge has been associated with increased concern. But among people who are skeptical about scientists and among Republicans more knowledge was generally not associated with greater concern. The association of knowledge with concern among Democrats and Independents who trust scientists was mediated by perceptions of consensus among scientists about GW's existence and by perceptions that humans are a principal cause of GW. Moreover, additional analyses of panel survey data produced findings consistent with the notion that more knowledge yields more concern among Democrats and Independents, but not among Republicans. Thus, when studying the relation of knowledge and concern, it is important to take into account the content of the information that different types of people acquire and choose to rely upon.

The network's mission is to place Earth in its cosmic context to encourage participants to explore connections between social & ecological issues in their backyards. Worldviews launched with informal science institution partners: the American Museum of Natural History, the Perot Museum of Nature & Science, the Journey Museum, the Bell Museum of Natural History, the University of Michigan Natural History Museum, and the National Environmental Modeling & Analysis Center. Worldviews uses immersive visualization technology to engage public audiences on issues of global environmental change at a bioregional level. An immersive planetarium show and dialogue deepens public engagement and awareness of complex human-natural system interactions. People have altered the global climate system. Our communities are increasingly vulnerable to extreme weather events. Land use decisions that people make every day put both human lives and biodiversity at risk through direct and indirect effects. The Worldviews programs demonstrate the complex linkages between Earth's physical and biological systems and their relationship to human health, agriculture, infrastructure, water resources, and energy. We have focused on critical thresholds, such as freshwater use, biodiversity loss, land use change, and anthropogenic changes to the nitrogen and phosphorus cycles. We have been guided by environmental literacy principles to help our audiences understand that humans drive current trends in coupled human-natural systems--and that humans could choose to play an important role in reversing these trends. Museum and planetarium staff members join the Worldviews Network team and external advisers to produce programs that span cosmic, global, and

    Liebe, Ulf

    2010-01-01

    A large number of ‘environmental justice’ studies show that wealthier people are less affected by environmental burdens and also consume more resources than poorer people. Given this double inequity, we ask, to what extent are affluent people prepared to pay to protect the environment? The analyses are couched within the compensation/affluence hypothesis, which states that wealthier persons are able to spend more for environmental protection than their poorer counterparts. Further, we take into account various competing economic, psychological and sociological determinants of individuals’ willingness to pay (WTP) for both public environmental goods (e.g., general environmental protection) and quasi-private environmental goods (e.g., CO2-neutral cars). Such a comprehensive approach contrasts with most other studies in this field that focus on a limited number of determinants and goods. Multivariate analyses are based on a general population survey in Switzerland (N = 3,369). Although income has a positive and significant effect on WTP supporting the compensation hypothesis, determinants such as generalized interpersonal trust that is assumed to be positively associated with civic engagement and environmental concern prove to be equally important. Moreover, we demonstrate for the first time that time preferences can considerably influence survey-based WTP for environmental goods; since investments in the environment typically pay off in the distant future, persons with a high subjective discount rate are less likely to commit.

    Industrial renewal in the bio/nanopharma sector is important for the long term strength of the Australian economy and for the health of its citizens. A variety of factors, however, may have caused inadequate attention to focus on systematically promoting domestic generic and small biotechnology manufacturers in Australian health policy. Despite recent clarifications of 'springboarding' capacity in intellectual property legislation, federal government requirements for specific generic price reductions on market entry and the potential erosion of reference pricing through new F1 and F2 categories for the purposes of Pharmaceutical Benefits Scheme (PBS) assessments, do not appear to be coherently designed to sustainably position this industry sector in 'biologics,' nanotherapeutics and pharmacogenetics. There also appears to have been little attention paid in this context to policies fostering industry sustainability and public affordability (as encouraged by the National Medicines Policy). One notable example includes that failure to consider facilitating mutual exchanges on regulatory assessment of health technology safety and cost-effectiveness (including reference pricing) in the context of ongoing free trade negotiations between Australia and China (the latter soon to possess the world's largest generic pharmaceutical manufacturing capacity). The importance of a thriving Australian domestic generic pharmaceutical and bio/nano tech industry in terms of biosecurity, similarly appears to have been given insufficient policy attention. Reasons for such policy oversights may relate to increasing interrelationships between generic and 'brand-name' manufacturers and the scale of investment required for the Australian generics and bio/nano technology sector to be a significant driver of local production. It might also result from singularly effective lobbying pressure exerted by Medicines Australia, the 'brand-name' pharmaceutical industry association, utilising

    Global research knowledge has accumulated over the past few decades, and there is reasonable evidence for a positive association between Mycobacterium avium spp. paratuberculosis and Crohn's disease in humans, although its role as a human pathogen has not been entirely accepted. For this reason, management of public health risk due to M. paratuberculosis remains an important policy issue in agri-food public health arenas in many countries. Responsible authorities must decide whether existing mitigation strategies are sufficient to prevent or reduce human exposure to M. paratuberculosis. A Web-based questionnaire was administered to topic specialists to elicit empirical knowledge and opinion on the overall public health impact of M. paratuberculosis, the importance of various routes of human exposure to the pathogen, existing mitigation strategies and the need for future strategies. The questionnaire had four sections and consisted of 20 closed and five open questions. Topic specialists believed that M. paratuberculosis is likely a risk to human health (44.8%) and, given the paucity of available evidence, most frequently ranked it as a moderate public health issue (40.1%). A significant correlation was detected between topic specialists' commitment to M. paratuberculosis in terms of the number of years or proportion of work dedicated to this topic, and the likelihood of an extreme answer (high or low) to the above questions. Topic specialists identified contact with ruminants and dairy products as the most likely routes of exposure for humans. There was consensus on exposure routes for ruminants and what commodities to target in mitigation efforts. Described mandatory programmes mainly focused on culling diseased animals and voluntary on-farm prevention programmes. Despite ongoing difficulties in the identification of subclinical infections in animals, the topic specialists largely agreed that further enhancement of on-farm programmes in affected commodities by

    Chronic kidney disease (CKD) is increasingly recognized as a global public health problem. There is now convincing evidence that CKD can be detected using simple laboratory tests, and that treatment can prevent or delay complications of decreased kidney function, slow the progression of kidney disease, and reduce the risk of cardiovascular disease (CVD). Translating these advances to simple and applicable public health measures must be adopted as a goal worldwide. Understanding the relationship between CKD and other chronic diseases is important to developing a public health policy to improve outcomes. The 2004 Kidney Disease Improving Global Outcomes (KDIGO) Controversies Conference on 'Definition and Classification of Chronic Kidney Disease' represented an important endorsement of the Kidney Disease Outcome Quality Initiative definition and classification of CKD by the international community. The 2006 KDIGO Controversies Conference on CKD was convened to consider six major topics: (1) CKD classification, (2) CKD screening and surveillance, (3) public policy for CKD, (4) CVD and CVD risk factors as risk factors for development and progression of CKD, (5) association of CKD with chronic infections, and (6) association of CKD with cancer. This report contains the recommendations from the meeting. It has been reviewed by the conference participants and approved as position statement by the KDIGO Board of Directors. KDIGO will work in collaboration with international and national public health organizations to facilitate implementation of these recommendations.

  2. Integrating the issues of global and veterinary public health into the veterinary education curriculum: an Australian perspective.

    2009-08-01

    This article discusses the integration of global and veterinary public health issues into the Australian veterinary curriculum. Formal veterinary education in Australia has a history of over 100 years and veterinarians have played a major role in the control of zoonotic and transboundary diseases for an even longer period. Australia is the largest exporter of red meat and live animals in the world. Therefore, educating veterinarians to promote and ensure food safety and animal welfare is prominent in Australian veterinary curricula. Veterinary degrees are accredited to allow Australian graduates to work professionally overseas, including in the United Kingdom and United States of America, and, in recent years, globalisation of the student body at Australian veterinary schools has occurred. For this reason, an appropriately broad curriculum is required to produce graduates who are able to address challenges in veterinary public health throughout the world. A Public Health University Network has been established to harmonise the veterinary public health curricula at the various veterinary schools and to develop the 'Australian veterinary public health philosophy', with its links to global issues and the 'One World, One Health' concept. Finally, conclusions are drawn on the implications of veterinary public health teaching in Australia and the preparation of Australian graduates for the global profession.

  3. Assessment of Costs for a Global Climate Fund Against Public Sector Disaster Risks

    National governments are key actors in managing climate variability and change, yet, many countries, faced with exhausted tax bases, high levels of indebtedness and limited donor assistance, have been unable to raise sufficient and timely capital to replace or repair damaged assets and restore livelihoods following major disasters exacerbating the impacts of disaster shocks on poverty and development. For weather extremes, which form a subset of the adaptation challenge and are supposed to increase in intensity and frequency with a changing climate, we conduct an assessment of the costs of managing and financing today's public sector risks on a global scale for more than 180 countries. A countries financial vulnerability is defined as a function of its financial resilience and its exposure to disaster risk. While disaster risk is estimated in terms of asset loss distributions based on catastrophe modeling approaches, financial resilience is operationalized as the public sector's ability to pay for relief to the affected population and support the reconstruction of affected assets and infrastructure for a given event. We consider governments financially vulnerable to disasters if they cannot access sufficient funding after a disaster to cover their liabilities. We operationalize this concept by the term resource gap, which we define the net loss associated with a disaster event after exhausting all possible ex-post and ex ante financing sources. Extending this approach for all possible disaster events, the risk that a resource gap will occur over a given time-span can be calculated for each country individually and dependent on the risk level different risk instruments may have to be applied. Furthermore, our estimates may inform decisions pertaining to a "climate insurance fund" absorbing "high level" country risks exceeding the ability of any given country to pay in the case of an extreme event. Our estimates relate to today's climate, yet we suggest that

    2004-01-01

    Background Tuberculosis is a major cause of morbidity and mortality globally. Recent scholarly attention to public health ethics provides an opportunity to analyze several ethical issues raised by the global tuberculosis pandemic. Discussion Recently articulated frameworks for public health ethics emphasize the importance of effectiveness in the justification of public health action. This paper critically reviews the relationship between these frameworks and the published evidence of effectiveness of tuberculosis interventions, with a specific focus on the controversies engendered by the endorsement of programs of service delivery that emphasize direct observation of therapy. The role of global economic inequities in perpetuating the tuberculosis pandemic is also discussed. Summary Tuberculosis is a complex but well understood disease that raises important ethical challenges for emerging frameworks in public health ethics. The exact role of effectiveness as a criterion for judging the ethics of interventions needs greater discussion and analysis. Emerging frameworks are silent about the economic conditions contributing to the global burden of illness associated with tuberculosis and this requires remediation. PMID:15113419

    This article defines global history in relation to the history of medicine and public health. It argues that a global approach to history opens up a space for examining the reverberations transmitted from the geographic periphery towards western regions, which have traditionally dominated modern historiography. It analyzes two medical interventions in the Caribbean in the late nineteenth and early twentieth century, showing how these events had profound consequences in the USA. The successes achieved in the Caribbean in terms of yellow fever and ancylostoma control, as well as providing a model for health campaigns in the southern USA, inspired the centralization of public health in North America under the centralizing control of the federal government.

    Good governance (GG) is an important concept that has evolved as a set of normative principles for low- and middle-income countries (LMICs) to strengthen the functional capacity of their public bodies, and as a conditional prerequisite to receive donor funding. Although much is written on good governance, very little is known on how to implement it. This paper documents the process of developing a strategy to implement a GG model for Health Technology Management (HTM) in the public health sector, based on lessons learned from twenty years of experience in policy development and implementation in Benin. The model comprises six phases: (i) preparatory analysis, assessing the effects of previous policies and characterizing the HTM system; (ii) stakeholder identification and problem analysis, making explicit the perceptions of problems by a diverse range of actors, and assessing their ability to solve these problems; (iii) shared analysis and visioning, delineating the root causes of problems and hypothesizing solutions; (iv) development of policy instruments for pilot testing, based on quick-win solutions to understand the system’s responses to change; (v) policy development and validation, translating the consensus solutions identified by stakeholders into a policy; and (vi) policy implementation and evaluation, implementing the policy through a cycle of planning, action, observation and reflection. The policy development process can be characterized as bottom-up, with a central focus on the participation of diverse stakeholders groups. Interactive and analytical tools of action research were used to integrate knowledge amongst actor groups, identify consensus solutions and develop the policy in a way that satisfies criteria of GG. This model could be useful for other LMICs where resources are constrained and the majority of healthcare technologies are imported. PMID:28056098

  15. The Educated Citizen and Global Public-Health Issues: One Model for Integration into the Undergraduate Curriculum.

    PubMed

    Caron, Rosemary M

    2016-01-01

    The Educated Citizen Initiative proposes that an understanding of public-health issues is a core component of an educated citizenry and is essential to develop one's societal responsibility. This initiative supports the Institute of Medicine's recommendation that "all undergraduates should have access to education in public health." Furthermore, the Liberal Education and America's Promise (LEAP) framework developed by the Association of American Colleges and Universities supports the "integration of public-health education into general and liberal education with an aim to produce an educated citizenry." The LEAP framework is implemented by teaching about the role of social determinants in a population's health status; the significance of personal and social responsibility; and providing skills for inquiry, critical thinking, problem solving, and evaluation. This article describes one university's experience in generating an educated citizenry cognizant of comprehensive public-health conflicts, thus contributing to both a local and global perspective on learning.

    Background In their safety evaluations of bisphenol A (BPA), the U.S. Food and Drug Administration (FDA) and a counterpart in Europe, the European Food Safety Authority (EFSA), have given special prominence to two industry-funded studies that adhered to standards defined by Good Laboratory Practices (GLP). These same agencies have given much less weight in risk assessments to a large number of independently replicated non-GLP studies conducted with government funding by the leading experts in various fields of science from around the world. Objectives We reviewed differences between industry-funded GLP studies of BPA conducted by commercial laboratories for regulatory purposes and non-GLP studies conducted in academic and government laboratories to identify hazards and molecular mechanisms mediating adverse effects. We examined the methods and results in the GLP studies that were pivotal in the draft decision of the U.S. FDA declaring BPA safe in relation to findings from studies that were competitive for U.S. National Institutes of Health (NIH) funding, peer-reviewed for publication in leading journals, subject to independent replication, but rejected by the U.S. FDA for regulatory purposes. Discussion Although the U.S. FDA and EFSA have deemed two industry-funded GLP studies of BPA to be superior to hundreds of studies funded by the U.S. NIH and NIH counterparts in other countries, the GLP studies on which the agencies based their decisions have serious conceptual and methodologic flaws. In addition, the U.S. FDA and EFSA have mistakenly assumed that GLP yields valid and reliable scientific findings (i.e., “good science”). Their rationale for favoring GLP studies over hundreds of publically funded studies ignores the central factor in determining the reliability and validity of scientific findings, namely, independent replication, and use of the most appropriate and sensitive state-of-the-art assays, neither of which is an expectation of industry-funded GLP

    We drew on two agenda-setting theories usually applied at the state or national level to assess their utility at the global level: Kingdon's multiple streams theory and Baumgartner and Jones's punctuated equilibrium theory. We illustrate our analysis with findings from a qualitative study of the International Labor Organization's Decent Work Agenda. We found that both theories help explain the agenda-setting mechanisms that operate in the global context, including how windows of opportunity open and what role institutions play as policy entrepreneurs. Future application of these theories could help characterize power struggles between global actors, whose voices are heard or silenced, and their impact on global policy agenda setting.

    Background Achieving national reductions in greenhouse gas emissions will require public support for climate and energy policies and changes in population behaviors. Audience segmentation – a process of identifying coherent groups within a population – can be used to improve the effectiveness of public engagement campaigns. Methodology/Principal Findings In Fall 2008, we conducted a nationally representative survey of American adults (n = 2,164) to identify audience segments for global warming public engagement campaigns. By subjecting multiple measures of global warming beliefs, behaviors, policy preferences, and issue engagement to latent class analysis, we identified six distinct segments ranging in size from 7 to 33% of the population. These six segments formed a continuum, from a segment of people who were highly worried, involved and supportive of policy responses (18%), to a segment of people who were completely unconcerned and strongly opposed to policy responses (7%). Three of the segments (totaling 70%) were to varying degrees concerned about global warming and supportive of policy responses, two (totaling 18%) were unsupportive, and one was largely disengaged (12%), having paid little attention to the issue. Certain behaviors and policy preferences varied greatly across these audiences, while others did not. Using discriminant analysis, we subsequently developed 36-item and 15-item instruments that can be used to categorize respondents with 91% and 84% accuracy, respectively. Conclusions/Significance In late 2008, Americans supported a broad range of policies and personal actions to reduce global warming, although there was wide variation among the six identified audiences. To enhance the impact of campaigns, government agencies, non-profit organizations, and businesses seeking to engage the public can selectively target one or more of these audiences rather than address an undifferentiated general population.

    The National Center for Atmospheric Research in Boulder Colorado is a leading research institution in the area of global and climate change research worldwide. As a component of NCAR's mission in research, education, and service, NCAR supports numerous programs designed to bring this science to different audiences in order to promote better understanding of climate and global change research as well as its relevance in learning contexts. Our climate and global change education and outreach effort targets several audiences, including online and in-person professional development for middle and high school educators, exhibits, tours, websites, and development of educational resources on climate and global change topics. The design of our program intentionally leverages resources in support of multiple audiences (including Spanish-speakers) in different settings. Beginning in 2006, building on relationships developed through the Megacity Initiative: Local and Global Research Observations (MILAGRO) campaign, we began to expand our collaborations with scientists and educators in Latin America, including Mexico and Chile.

  3. "Integrated knowledge translation" for globally oriented public health practitioners and scientists: Framing together a sustainable transfrontier knowledge translation vision.

    PubMed

    Lapaige, Véronique

    2010-06-01

    The development of a dynamic leadership coalition between practitioners and researchers/scientists - which is known in Canada as integrated knowledge translation (KT) - can play a major role in bridging the know-do gap in the health care and public health sectors. In public health, and especially in globally oriented public health, integrated KT is a dynamic, interactive (collaborative), and nonlinear phenomenon that goes beyond a reductionist vision of knowledge translation, to attain inter-, multi-, and even transdisciplinary status. Intimately embedded in its socioenvironmental context and closely connected with the complex interventions of multiple actors, the nonlinear process of integrated KT is based on a double principle: (1) the principle of transcendence of frontiers (sectorial, disciplinary, geographic, cultural, and cognitive), and (2) the principle of integration of knowledge beyond these frontiers. However, even though many authors agree on the overriding importance of integrated KT, there is as yet little understanding of the causal framework of integrated KT. Here, one can ask two general questions. Firstly, what "determines" integrated KT? Secondly, even if one wanted to apply a "transfrontier knowledge translation" vision, how should one go about doing so? For example, what would be the nature and qualities of a representative research program that applied a "transfrontier collaboration" approach? This paper focuses on the determinants of integrated KT within the burgeoning field of knowledge translation research (KT research). The paper is based on the results of a concurrent mixed method design which dealt with the complexity of building and sustaining effective coalitions and partnerships in the health care and public health sectors. The aims of this paper are: (1) to present an "integrated KT" conceptual framework which is global-context-sensitive, and (2) to promote the incorporation of a new "transfrontier knowledge translation" approach

    Existing ethics guidelines, influential literature and policies on ethical research generally focus on real-time data collection from humans. They enforce individual rights and liberties, thereby lowering need for aggregate protections. Although dependable, emerging public health research paradigms like research using public health data (RUPD) raise new challenges to their application. Unlike traditional research, RUPD is population-based, aligned to public health activities, and often reliant on pre-collected longitudinal data. These characteristics, when considered in relation to the generally lower protective ethico-legal frameworks of the Global South, including Africa, highlight ethical gaps. Health and demographic surveillance systems are examples of public health programs that accommodate RUPD in these contexts. We set out to explore the perspectives of professionals with a working knowledge of these systems to determine practical ways of appropriating the foundational principles of health research to advance the ever growing opportunities in RUPD. We present their perspectives and in relation to the literature and our ethical analysis, make context relevant recommendations. We further argue for the development of a framework founded on the discussions and recommendations as a minimum base for achieving optimal ethics for optimal RUPD in the Global South.

    Globalization magnifies the problems that affect all people and that require large-scale human cooperation, for example, the overharvesting of natural resources and human-induced global warming. However, what does globalization imply for the cooperation needed to address such global social dilemmas? Two competing hypotheses are offered. One hypothesis is that globalization prompts reactionary movements that reinforce parochial distinctions among people. Large-scale cooperation then focuses on favoring one's own ethnic, racial, or language group. The alternative hypothesis suggests that globalization strengthens cosmopolitan attitudes by weakening the relevance of ethnicity, locality, or nationhood as sources of identification. In essence, globalization, the increasing interconnectedness of people worldwide, broadens the group boundaries within which individuals perceive they belong. We test these hypotheses by measuring globalization at both the country and individual levels and analyzing the relationship between globalization and individual cooperation with distal others in multilevel sequential cooperation experiments in which players can contribute to individual, local, and/or global accounts. Our samples were drawn from the general populations of the United States, Italy, Russia, Argentina, South Africa, and Iran. We find that as country and individual levels of globalization increase, so too does individual cooperation at the global level vis-à-vis the local level. In essence, "globalized" individuals draw broader group boundaries than others, eschewing parochial motivations in favor of cosmopolitan ones. Globalization may thus be fundamental in shaping contemporary large-scale cooperation and may be a positive force toward the provision of global public goods.

    Global health governance benefits from participants well-versed in the realities of international policy-making. Consequently, educational programmes must establish more opportunities for students to engage in global health policy development. This paper examines a unique global health governance and diplomacy practicum programme at the University of Southern California, designed for Master of Public Health candidates. Through the programme, students act as official non-governmental delegates to the World Health Assembly in Geneva, Switzerland through organisational partnerships. Students and collaborating organisations were asked to complete an online post-participation survey examining the perceived quality of the experience. Through the survey, students indicated reinforcement of classroom learning, continued or heightened interest in global health policy and enthusiasm in recommending the programme to other students. Organisations perceived students to be adequately prepared and indicated their continued desire to work with students in the programme. The data collected suggest that the programme was successful in providing students with a worthwhile experience that developed skills in global health diplomacy and promoted interest and critical thinking concerning international policy-making processes. A discussion of strengths and challenges serves as a blueprint for the creation of future practicum programmes.

    Differences in the relative use of global and local information (seeing the forest vs. the trees) may explain why people with social anxiety often do not benefit from corrective feedback, even though they pay close attention to details in social situations. In the current study, participants high (n=43) or low (n=47) in social anxiety symptoms gave a series of brief speeches, and then self-rated their speaking performance on items reflecting global and local performance indicators (self-assessment) and also received standardized performance feedback from an experimenter. Participants then completed a questionnaire asking how they thought the experimenter would rate their performance based on the feedback provided (experimenter assessment). Participants completed the self- and experimenter assessments again after 3 days, in addition to a measure of postevent processing (repetitive negative thinking) about their speech performance. Results showed that, as hypothesized, the High SA group rated their performance more negatively than the Low SA group. Moreover, the High SA group's ratings of global aspects of their performance became relatively more negative over time, compared to their ratings of local aspects and the Low SA group's ratings. As expected, postevent processing mediated the relationship between social anxiety group status and worsening global performance evaluations. These findings point to a pattern of progressively more negative global evaluations over time for persons high in social anxiety.

    Throughout their life, humans often engage in collective endeavors ranging from family related issues to global warming. In all cases, the tragedy of the commons threatens the possibility of reaching the optimal solution associated with global cooperation, a scenario predicted by theory and demonstrated by many experiments. Using the toolbox of evolutionary game theory, I will address two important aspects of evolutionary dynamics that have been neglected so far in the context of public goods games and evolution of cooperation. On one hand, the fact that often there is a threshold above which a public good is reached [1, 2]. On the other hand, the fact that individuals often participate in several games, related to the their social context and pattern of social ties, defined by a social network [3, 4, 5]. In the first case, the existence of a threshold above which collective action is materialized dictates a rich pattern of evolutionary dynamics where the direction of natural selection can be inverted compared to standard expectations. Scenarios of defector dominance, pure coordination or coexistence may arise simultaneously. Both finite and infinite population models are analyzed. In networked games, cooperation blooms whenever the act of contributing is more important than the effort contributed. In particular, the heterogeneous nature of social networks naturally induces a symmetry breaking of the dilemmas of cooperation, as contributions made by cooperators may become contingent on the social context in which the individual is embedded. This diversity in context provides an advantage to cooperators, which is particularly strong when both wealth and social ties follow a power-law distribution, providing clues on the self-organization of social communities. Finally, in both situations, it can be shown that individuals no longer play a defection dominance dilemma, but effectively engage in a general N-person coordination game. Even if locally defection may seem

    Globalization magnifies the problems that affect all people and that require large-scale human cooperation, for example, the overharvesting of natural resources and human-induced global warming. However, what does globalization imply for the cooperation needed to address such global social dilemmas? Two competing hypotheses are offered. One hypothesis is that globalization prompts reactionary movements that reinforce parochial distinctions among people. Large-scale cooperation then focuses on favoring one's own ethnic, racial, or language group. The alternative hypothesis suggests that globalization strengthens cosmopolitan attitudes by weakening the relevance of ethnicity, locality, or nationhood as sources of identification. In essence, globalization, the increasing interconnectedness of people worldwide, broadens the group boundaries within which individuals perceive they belong. We test these hypotheses by measuring globalization at both the country and individual levels and analyzing the relationship between globalization and individual cooperation with distal others in multilevel sequential cooperation experiments in which players can contribute to individual, local, and/or global accounts. Our samples were drawn from the general populations of the United States, Italy, Russia, Argentina, South Africa, and Iran. We find that as country and individual levels of globalization increase, so too does individual cooperation at the global level vis-à-vis the local level. In essence, “globalized” individuals draw broader group boundaries than others, eschewing parochial motivations in favor of cosmopolitan ones. Globalization may thus be fundamental in shaping contemporary large-scale cooperation and may be a positive force toward the provision of global public goods. PMID:19255433

    Global self-esteem was tested to predict quicker cardiovascular adaptation during stressful oral thesis presentation and faster habituation from the first to the second and third thesis presentations. Nineteen graduate students initially rated their global self-esteem and afterwards orally presented their theses proposals in 20-min presentations to their thesis supervisor and peers. A second and third presentation of the revised thesis concepts took place at 4-weeks intervals. Ambulatory blood pressure and heart rate were assessed repeatedly during the presentations. Post-talk self ratings of stressfulness indicated presentations to be a strong public speaking stressor. One hundred and thirty-eight measurements of systolic (SBP), diastolic blood pressure (DBP), and heart rate (HR) showed a significant adaptation (decrease) during presentations. There was an overall mean level decrease from the first to the second, and the second to the third presentations in HR, but not in SBP and DBP. However, habituation in SBP and DBP across three presentations was significantly faster (p < .05) in those participants who initially reported higher levels of global self-esteem. Higher global self-esteem did not foster adaptation within the presentations. Self-esteem is discussed as an important individual resource that allows successful coping with recurring evaluative threats.

    A low body mass index in older people has been associated with increased mortality. The main objective of this study was to identify factors associated with low body mass indices [ BMIs] (< 18.5 kg/m2) in older residents of shelter care facilities in Peninsular Malaysia. 1081 elderly people (59% M) over the age of 60 years were surveyed using questionnaires determining baseline demographics, nutritional and cognitive status, physical function and psychological well being. Body mass index was also determined. Subjects were recruited from publicly funded shelter homes in Peninsular Malaysia. 14.3% of residents had BMIs < 18.5 kg/m2. Multivariate analyses (adjusted for age and sex) revealed that having no family (RR 1.98[95%CI 1.40-2.82], p<0.001) and negative responses to statement 3 [I eat few fruits or vegetables or milk products] (RR 0.62 [95% CI 0.42-0.90]; P= 0.013) and statement 5 [I have tooth or mouth problems that make it hard for me to eat] (RR 0.69 [95%CI 0.50-0.96]; P= 0.023) of the ' Determine Your Nutritional Health Checklist' were independently associated with low BMIs (<18.5 kg/m2). Older people with no family support were at risk of becoming underweight. Older people who consumed fruits, vegetables or milk or had good oral health were less likely to be underweight. Nutrient intake, oral health and social support were important in ensuring healthy body weight in older Malaysians.

  13. Exploring Patterns of Soil Organic Matter Decomposition with Students and the Public Through the Global Decomposition Project (GDP)

    The Global Decomposition Project (GDP) is a program designed to introduce and educate students and the general public about soil organic matter and decomposition through a standardized protocol for collecting, reporting, and sharing data. This easy-to-use hands-on activity focuses on questions such as "How do environmental conditions control decomposition of organic matter in soil?" and "Why do some areas accumulate organic matter and others do not?" Soil organic matter is important to local ecosystems because it affects soil structure, regulates soil moisture and temperature, and provides energy and nutrients to soil organisms. It is also important globally because it stores a large amount of carbon, and when microbes "eat", or decompose organic matter they release greenhouse gasses such as carbon dioxide and methane into the atmosphere, which affects the earth's climate. The protocol describes a commonly used method to measure decomposition using a paper made of cellulose, a component of plant cell walls. Participants can receive pre-made cellulose decomposition bags, or make decomposition bags using instructions in the protocol and easily obtained materials (e.g., window screen and lignin-free paper). Individual results will be shared with all participants and the broader public through an online database. We will present decomposition bag results from a research site in Alaskan tundra, as well as from a middle-school-student led experiment in California. The GDP demonstrates how scientific methods can be extended to educate broader audiences, while at the same time, data collected by students and the public can provide new insight into global patterns of soil decomposition. The GDP provides a pathway for scientists and educators to interact and reach meaningful education and research goals.

    Global health is a dynamic, emerging, and interdisciplinary field. To address current and emerging global health challenges, we need a public health workforce with adaptable and collaborative problem-solving skills. In the 2013-2014 academic year, the Hubert Department of Global Health at the Rollins School of Public Health-Emory University launched an innovative required core course for its first-year Master of Public Health students in the global health track. The course uses a case-based, problem-based learning approach to develop global health competencies. Small teams of students propose solutions to these problems by identifying learning issues and critically analyzing and synthesizing new information. We describe the course structure and logistics used to apply this approach in the context of a large class and share lessons learned.

    On July 15, 2009, the National Academy of Sciences (NAS) released a report, Scientific Value of Arctic Sea Ice Imagery Derived Products, advocating public release of Arctic images derived from classified data. In the NAS press release that announced the release, report lead Stephanie Pfirman states "To prepare for a possibly ice-free Arctic and its subsequent effects on the environment, economy, and national security, it is critical to have accurate projections of changes over the next several decades." In the same release NAS President Ralph Cicerone states "We hope that these images are the first of many that could help scientists learn how the changing climate could impact the environment and our society." The same day, Secretary of the Interior Ken Salazar announced that the requested images had been released and were available to the public on a US Geological Survey Global Fiducials Program (GFP) Library website (http://gfl.usgs.gov). The website was developed by the USGS to provide public access to the images and to support environmental analysis of global climate-related science. In the statement describing the release titled, Information Derived from Classified Materials Will Aid Understanding of Changing Climate, Secretary Salazar states "We need the best data from all places if we are to meet the challenges that rising carbon emissions are creating. This information will be invaluable to scientists, researchers, and the public as we tackle climate change." Initially about 700 Arctic sea ice images were released. Six years later, the number exceeds 1,500. The GFP continues to facilitate the acquisition of new Arctic sea ice imagery from US National Imagery Systems. This example demonstrates how information about dynamically changing Arctic sea ice continues to be effectively communicated to the public by the GFP. In addition to Arctic sea ice imagery, the GFP has publicly released imagery time series of more than 125 other environmentally important

    The impact of weather change and global pollution on the development and/or the transformation of microorganisms is no longer to be demonstrated. In this respect, heavy trends can be taken into account. This general context needs the development of anticipation procedures and the knowledge of the perception of prevention by the public for short, medium and long term actions. After a short discussion on the concept of emerging issues, the authors present some past examples of public health programs. These examples (malaria, dengue, chikungunya and cholera) are used to propose optimized ways of decision/action that may help to avoid possible crisis in a rapidly changing world. Then, the different lessons learnt are, under certain limits, associated with a forecasting analysis.
