    2013-05-01

    Cooperation in animals and humans is widely observed even if evolutionary biology theories predict the evolution of selfish individuals. Previous game theory models have shown that cooperation can evolve when the game takes place in a structured population such as a social network because it limits interactions between individuals. Modularity, the natural division of a network into groups, is a key characteristic of all social networks but the influence of this crucial social feature on the evolution of cooperation has never been investigated. Here, we provide novel pieces of evidence that network modularity promotes the evolution of cooperation in 2-person prisoner's dilemma games. By simulating games on social networks of different structures, we show that modularity shapes interactions between individuals favouring the evolution of cooperation. Modularity provides a simple mechanism for the evolution of cooperation without having to invoke complicated mechanisms such as reputation or punishment, or requiring genetic similarity among individuals. Thus, cooperation can evolve over wider social contexts than previously reported.

    During the Anthropocene, mankind will face several global environmental challenges. One of the first and more successful responses provided by Science to these challenges is the collecting of long-term series of biophysical variables in order to improve our knowledge of natural systems. The huge amount of information gathered during the last decades by Research Infrastructures (RIs) has helped to understand the structure and functioning of natural systems at local and regional scales. But how can we address the global cross-scale and cross-disciplinary challenges posed by the global environment change? We believe that it will be necessary to observe, model better and understand the whole biosphere using long term data generated by international RIs. RIs play a key role on many of the last advances and discoveries in science, from the observation of the Higgs Boson at CERN to the exploration of the Universe by the telescopes of the European Southern Observatory in Chile. The scale of complexity, instrumentation, computing resources, technological advances, and also of the investments, and the size of research collaborations, do not have precedents in Science. RIs in environmental field are developing fast, but the corresponding communities need yet to further reflect the need for a wider global collaboration because the challenges to tackle are in essence of global nature. This contribution describes how COOP+ project (EU Horizon 2020 Coordination and Support Action) will promote the cooperation among RIs at a global scale to address global environmental challenges. Our project evolves from the experience of the sucessful FP7 COOPEUS project (see http://www.coopeus.eu), which explored the use and access to data from RIs in environmental research in Europe and USA. The general goal of COOP+ is to strengthen the links and coordination of the ESFRI RIs related to Marine Science (EMSO), Arctic and Atmospheric Research (EISCAT), Carbon Observation (ICOS) and Biodiversity

  3. An Integrated Strategy for Promoting Geoscience Education and Research in Developing Countries through International Cooperation

    Geoscience education and research in Developing countries should aim at achieving food, water and environmental security, and disaster preparedness, based on the synergetic application of earth (including atmospheric and oceanic realms), space and information sciences through economically-viable, ecologically- sustainable and people-participatory management of natural resources. The proposed strategy involves the integration of the following three principal elements: (i) What needs to be taught: Geoscience needs to be taught as earth system science incorporating geophysical, geochemical and geobiological approaches, with focus (say, 80 % of time) on surficial processes (e.g. dynamics of water, wind and waves, surface and groundwater, soil moisture, geomorphology, landuse, crops), and surficial materials (e.g. soils, water, industrial minerals, sediments, biota). Subjects such as the origin, structure and evolution of the earth, and deep-seated processes (e.g. dynamics of the crust-mantle interaction, plate tectonics) could be taught by way of background knowledge (say, 20 % of the time), (ii) How jobs are to be created: Jobs are to be created by merging geoscience knowledge with economic instruments (say, micro enterprises), and management structures at different levels (Policy level, Technology Transfer level and Implementation level), customized to the local biophysical and socioeconomic situations, and (iii) International cooperation: Web-based instruction (e.g. education portals, virtual laboratories) through South - South and North - South cooperation, customized to the local biophysical and socioeconomic situations, with the help of (say) UNDP, UNESCO, World Bank, etc.

    Despite an increased risk of mental health problems in adolescents with autism spectrum disorder (ASD), there is limited research on effective prevention approaches for this population. Funded by the Cooperative Research Centre for Living with Autism, a theoretically and empirically supported school-based preventative model has been developed to alter the negative trajectory and promote wellbeing and positive mental health in adolescents with ASD. This conceptual paper provides the rationale, theoretical, empirical and methodological framework of a multilayered intervention targeting the school, parents and adolescents on the spectrum. Two important interrelated protective factors have been identified in community adolescent samples, namely the sense of belonging (connectedness) to school and the capacity for self and affect regulation in the face of stress (i.e. resilience). We describe how a confluence of theories from social psychology, developmental psychology and family systems theory, along with empirical evidence (including emerging neurobiological evidence), supports the interrelationships between these protective factors and many indices of wellbeing. However, the characteristics of ASD (including social and communication difficulties, and frequently difficulties with changes and transitions, and diminished optimism and self-esteem) impair access to these vital protective factors. The paper describes how evidence-based interventions at the school level for promoting inclusive schools (using the Index for Inclusion) and interventions for adolescents and parents to promote resilience and belonging [using the Resourceful Adolescent Program (RAP)] are adapted and integrated for adolescents with ASD. This multisite proof-of-concept study will confirm whether this multilevel school-based intervention is promising, feasible and sustainable.

  6. Social penalty promotes cooperation in a cooperative society.

    2015-01-01

    Why cooperation is well developed in human society is an unsolved question in biological and human sciences. Vast studies in game theory have revealed that in non-cooperative games selfish behavior generally dominates over cooperation and cooperation can be evolved only under very limited conditions. These studies ask the origin of cooperation; whether cooperation can evolve in a group of selfish individuals. In this paper, instead of asking the origin of cooperation, we consider the enhancement of cooperation in a small already cooperative society. We ask whether cooperative behavior is further promoted in a small cooperative society in which social penalty is devised. We analyze hawk-dove game and prisoner's dilemma introducing social penalty. We then expand it for non-cooperative games in general. The results indicate that cooperation is universally favored if penalty is further imposed. We discuss the current result in terms of the moral, laws, rules and regulations in a society, e.g., criminology and traffic violation. PMID:26238521

  11. Benevolent Characteristics Promote Cooperative Behaviour among Humans

    PubMed Central

    Mylona, Kalliopi; Niblo, Graham A.

    2014-01-01

    Cooperation is fundamental to the evolution of human society. We regularly observe cooperative behaviour in everyday life and in controlled experiments with anonymous people, even though standard economic models predict that they should deviate from the collective interest and act so as to maximise their own individual payoff. However, there is typically heterogeneity across subjects: some may cooperate, while others may not. Since individual factors promoting cooperation could be used by institutions to indirectly prime cooperation, this heterogeneity raises the important question of who these cooperators are. We have conducted a series of experiments to study whether benevolence, defined as a unilateral act of paying a cost to increase the welfare of someone else beyond one's own, is related to cooperation in a subsequent one-shot anonymous Prisoner's dilemma. Contrary to the predictions of the widely used inequity aversion models, we find that benevolence does exist and a large majority of people behave this way. We also find benevolence to be correlated with cooperative behaviour. Finally, we show a causal link between benevolence and cooperation: priming people to think positively about benevolent behaviour makes them significantly more cooperative than priming them to think malevolently. Thus benevolent people exist and cooperate more. PMID:25140707

  12. Love or fear: can punishment promote cooperation?

    PubMed

    Kroupa, Sebestian

    2014-01-01

    Cooperation is a paradox: Why should one perform a costly behavior only to increase the fitness of another? Human societies, in which individuals cooperate with genetically unrelated individuals on a considerably larger scale than most mammals do, are especially puzzling in this regard. Recently, the threat of punishment has been given substantial attention as one of the mechanisms that could help sustain human cooperation in such situations. Nevertheless, using punishment to explain cooperation only leads to further questions: Why spend precious resources to penalize free-riders, especially if others can avoid this investment and cheaters can punish you back? Here, it is argued that current evidence supports punishment as an efficient means for the maintenance of cooperation, and that the gravity of proposed limitations of punishment for maintaining cooperation may have been overestimated in previous studies due to the features of experimental design. Most notably, the importance of factors as characteristic of human societies as reputation and language has been greatly neglected. Ironically, it was largely the combination of the two that enabled humans to shape costly punishment into numerous low-cost and less detrimental strategies that clearly can promote human cooperation.

  14. Inducing peer pressure to promote cooperation.

    PubMed

    Mani, Ankur; Rahwan, Iyad; Pentland, Alex

    2013-01-01

    Cooperation in a large society of self-interested individuals is notoriously difficult to achieve when the externality of one individual's action is spread thin and wide on the whole society. This leads to the 'tragedy of the commons' in which rational action will ultimately make everyone worse-off. Traditional policies to promote cooperation involve Pigouvian taxation or subsidies that make individuals internalize the externality they incur. We introduce a new approach to achieving global cooperation by localizing externalities to one's peers in a social network, thus leveraging the power of peer-pressure to regulate behavior. The mechanism relies on a joint model of externalities and peer-pressure. Surprisingly, this mechanism can require a lower budget to operate than the Pigouvian mechanism, even when accounting for the social cost of peer pressure. Even when the available budget is very low, the social mechanisms achieve greater improvement in the outcome. PMID:23619166

  17. How wealth accumulation can promote cooperation.

    PubMed

    Chadefaux, Thomas; Helbing, Dirk

    2010-01-01

    Explaining the emergence and stability of cooperation has been a central challenge in biology, economics and sociology. Unfortunately, the mechanisms known to promote it either require elaborate strategies or hold only under restrictive conditions. Here, we report the emergence, survival, and frequent domination of cooperation in a world characterized by selfishness and a strong temptation to defect, when individuals can accumulate wealth. In particular, we study games with local adaptation such as the prisoner's dilemma, to which we add heterogeneity in payoffs. In our model, agents accumulate wealth and invest some of it in their interactions. The larger the investment, the more can potentially be gained or lost, so that present gains affect future payoffs. We find that cooperation survives for a far wider range of parameters than without wealth accumulation and, even more strikingly, that it often dominates defection. This is in stark contrast to the traditional evolutionary prisoner's dilemma in particular, in which cooperation rarely survives and almost never thrives. With the inequality we introduce, on the contrary, cooperators do better than defectors, even without any strategic behavior or exogenously imposed strategies. These results have important consequences for our understanding of the type of social and economic arrangements that are optimal and efficient. PMID:21048947

  18. Centralized sanctioning and legitimate authority promote cooperation in humans

    Social sanctioning is widely considered a successful strategy to promote cooperation among humans. In situations in which individual and collective interests are at odds, incentives to free-ride induce individuals to refrain from contributing to public goods provision. Experimental evidence from public goods games shows that when endowed with sanctioning powers, conditional cooperators can discipline defectors, thus leading to greater levels of cooperation. However, extant evidence is based on peer punishment institutions, whereas in complex societies, systems of control are often centralized: for instance, we do not sanction our neighbors for driving too fast, the police do. Here we show the effect of centralized sanctioning and legitimate authority on cooperation. We designed an adaptation of the public goods game in which sanctioning power is given to a single monitor, and we experimentally manipulated the process by which the monitor is chosen. To increase the external validity of the study, we conducted lab-in-the-field experiments involving 1,543 Ugandan farmers from 50 producer cooperatives. This research provides evidence of the effectiveness of centralized sanctioning and demonstrates the causal effect of legitimacy on cooperation: participants are more responsive to the authority of an elected monitor than a randomly chosen monitor. Our essay contributes to the literature on the evolution of cooperation by introducing the idea of role differentiation. In complex societies, cooperative behavior is not only sustained by mechanisms of selection and reciprocity among peers, but also by the legitimacy that certain actors derive from their position in the social hierarchy.

  7. Relational diversity promotes cooperation in prisoner's dilemma games.

    PubMed

    Xu, Bo; Wang, Jianwei; Deng, Ruipu; Li, Miao

    2014-01-01

    Relational diversity can be characterized by heterogeneous distributions of tie strengths in social networks and this diversity is present not only among humans, but throughout the animal world. We account for this observation by analyzing two network datasets from Facebook. We measure the strength of a tie by calculating the extent of overlap of friends between the two individuals. Based on the previous findings in human experiments, we argue that it is very unlikely that players will allocate their investments equally to their neighbors. There is a tendency that players prefer to donate more to their intimate friends. We find that if players preferentially allocate their investments to their good friends, cooperation will be promoted in PDG. We proved that the facilitation of the cooperative strategy relies mostly on the cooperative allies between best friends, resulting in the formation of cooperative clusters which are able to prevail against the defectors even when there is a large cost to cooperate. Moreover, we discover that the effect of relational diversity cannot be analyzed by adopting classical complex networks models, because neither of the artificial networks is able to produce networks with diverse distributions of tie strengths. It is of vital importance to introduce real social networks to study the influence of diverse relations especially when it comes to humans. This research proposes a brand new perspective to understand the influence of social relations on the emergence of cooperation in evolutionary prisoner's dilemma games. PMID:25474354

  8. Spontaneous Giving under Structural Inequality: Intuition Promotes Cooperation in Asymmetric Social Dilemmas

    PubMed Central

    Lotz, Sebastian

    2015-01-01

    The present research investigates the role of intuitive mental processing on cooperation in experimental games involving structural inequality. Results from an experiment using conceptual priming to induce intuitive mental processing provide the first evidence that cooperation is promoted by intuition in an asymmetric context that distributes the gains from cooperation unequally among a group. Therefore, the results extend our understanding of the cognitive underpinnings of human cooperation by demonstrating the robustness of intuitive cooperation in games involving structural inequality regarding asymmetric gains from cooperation. Additionally, the results provide the first successful conceptual replication of the intuition-cooperation link using conceptual priming, therefore also contributing to the debate about the validity of previous research in other contexts. Taken together, the present research contributes to the literature on psychological and institutional mechanisms that promote cooperation. PMID:26154284

  12. Cooperative IASCC Research (CIR) Program

    SciTech Connect

    Nelson, J.L.

    1998-03-01

    Irradiation assisted stress corrosion cracking (IASCC) describes intergranular environmental cracking of material exposed to ionizing radiation. The implications of IASCC are significant, both in terms of repair and outage costs as well as the potential for cracking in components that may be extremely difficult to repair or replace. Significant advancements have been made in the understanding of IASCC. However, it is clear that major unknowns persist and must be understood and quantified before the life of a reactor component at risk from IASCC can be predicted or significantly extended. Although individual organizations are continuing to effectively address IASCC, it became apparent that a more direct form of cooperation would be more timely and efficient in addressing the technical issues. Thus in 1995 EPRI formed the Cooperative IASCC Research (CIR) Program. This is a cooperative, jointly funded effort with participants from eight countries providing financial support and technical oversight. The efforts of the CIR Program are directed at the highest priority questions in the areas of material susceptibility, water chemistry and material stress. Major research areas of the Program are: (1) evaluation of IASCC mechanisms, (2) development of methodology for predicting IASCC, and (3) quantification of irradiation effects on metallurgy, mechanics and electrochemistry. Studies to evaluate various IASCC mechanisms include work to better understand the possible roles of radiation-induced segregation (RIS), radiation microstructure, bulk and localized deformation effects, overall effects on strength and ductility, hydrogen and helium effects, and others. Experiments are being conducted to isolate individual effects and determine the relative importance of each in the overall IASCC mechanism. Screening tests will be followed by detailed testing to identify the contribution of each effect over a range of conditions. The paper describes the completed and ongoing work being

  13. Population Fluctuation Promotes Cooperation in Networks

    Miller, Steve; Knowles, Joshua

    2015-01-01

    We consider the problem of explaining the emergence and evolution of cooperation in dynamic network-structured populations. Building on seminal work by Poncela et al., which shows how cooperation (in one-shot prisoner’s dilemma) is supported in growing populations by an evolutionary preferential attachment (EPA) model, we investigate the effect of fluctuations in the population size. We find that a fluctuating model – based on repeated population growth and truncation – is more robust than Poncela et al.’s in that cooperation flourishes for a wider variety of initial conditions. In terms of both the temptation to defect, and the types of strategies present in the founder network, the fluctuating population is found to lead more securely to cooperation. Further, we find that this model will also support the emergence of cooperation from pre-existing non-cooperative random networks. This model, like Poncela et al.’s, does not require agents to have memory, recognition of other agents, or other cognitive abilities, and so may suggest a more general explanation of the emergence of cooperation in early evolutionary transitions, than mechanisms such as kin selection, direct and indirect reciprocity.

  16. Social image concerns promote cooperation more than altruistic punishment

    2016-01-01

    Human cooperation is enigmatic, as organisms are expected, by evolutionary and economic theory, to act principally in their own interests. However, cooperation requires individuals to sacrifice resources for each other's benefit. We conducted a series of novel experiments in a foraging society where social institutions make the study of social image and punishment particularly salient. Participants played simple cooperation games where they could punish non-cooperators, promote a positive social image or do so in combination with one another. We show that although all these mechanisms raise cooperation above baseline levels, only when social image alone is at stake do average economic gains rise significantly above baseline. Punishment, either alone or combined with social image building, yields lower gains. Individuals' desire to establish a positive social image thus emerges as a more decisive factor than punishment in promoting human cooperation. PMID:27504898

    Complex social behaviors lie at the heart of many of the challenges facing evolutionary biology, sociology, economics, and beyond. For evolutionary biologists the question is often how group behaviors such as collective action, or decision making that accounts for memories of past experience, can emerge and persist in an evolving system. Evolutionary game theory provides a framework for formalizing these questions and admitting them to rigorous study. Here we develop such a framework to study the evolution of sustained collective action in multi-player public-goods games, in which players have arbitrarily long memories of prior rounds of play and can react to their experience in an arbitrary way. We construct a coordinate system for memory-m strategies in iterated n-player games that permits us to characterize all cooperative strategies that resist invasion by any mutant strategy, and stabilize cooperative behavior. We show that, especially when groups are small, longer-memory strategies make cooperation easier to evolve, by increasing the number of ways to stabilize cooperation. We also explore the co-evolution of behavior and memory. We find that even when memory has a cost, longer-memory strategies often evolve, which in turn drives the evolution of cooperation, even when the benefits for cooperation are low. PMID:27247059

  20. Harnessing the power of reputation: strengths and limits for promoting cooperative behaviors.

    2012-01-01

    Evolutionary approaches have done much to identify the pressures that select for cooperative sentiment. This helps us understand when and why cooperation will arise, and applied research shows how these pressures can be harnessed to promote various types of cooperation. In particular, recent evidence shows how opportunities to acquire a good reputation can promote cooperation in laboratory and applied settings. Cooperation can be promoted by tapping into forces like indirect reciprocity, costly signaling, and competitive altruism. When individuals help others, they receive reputational benefits (or avoid reputational costs), and this gives people an incentive to help. Such findings can be applied to promote many kinds of helping and cooperation, including charitable donations, tax compliance, sustainable and pro-environmental behaviors, risky heroism, and more. Despite the potential advantages of using reputation to promote positive behaviors, there are several risks and limits. Under some circumstances, opportunities for reputation will be ineffective or promote harmful behaviors. By better understanding the dynamics of reputation and the circumstances under which cooperation can evolve, we can better design social systems to increase the rate of cooperation and reduce conflict.

  3. Promotion of cooperation by selective group extinction

    2016-06-01

    Multilevel selection is an important organizing principle that crucially underlies evolutionary processes from the emergence of cells to eusociality and the economics of nations. Previous studies on multilevel selection assumed that the effective higher-level selection emerges from lower-level reproduction. This leads to selection among groups, although only individuals reproduce. We introduce selective group extinction, where groups die with a probability inversely proportional to their group fitness. When accounting for this the critical benefit-to-cost ratio is substantially lowered. Because in game theory and evolutionary dynamics the degree of cooperation crucially depends on this ratio above which cooperation emerges, previous studies may have substantially underestimated the establishment and maintenance of cooperation.

  4. Special agents can promote cooperation in the population.

    2011-01-01

    Cooperation is ubiquitous in our real life but everyone would like to maximize her own profits. How does cooperation occur in the group of self-interested agents without centralized control? Furthermore, in a hostile scenario, for example, cooperation is unlikely to emerge. Is there any mechanism to promote cooperation if populations are given and play rules are not allowed to change? In this paper, numerical experiments show that complete population interaction is unfriendly to cooperation in the finite but end-unknown Repeated Prisoner's Dilemma (RPD). Then a mechanism called soft control is proposed to promote cooperation. According to the basic idea of soft control, a number of special agents are introduced to intervene in the evolution of cooperation. They comply with play rules in the original group so that they are always treated as normal agents. For our purpose, these special agents have their own strategies and share knowledge. The capability of the mechanism is studied under different settings. We find that soft control can promote cooperation and is robust to noise. Meanwhile simulation results demonstrate the applicability of the mechanism in other scenarios. Besides, the analytical proof also illustrates the effectiveness of soft control and validates simulation results. As a way of intervention in collective behaviors, soft control provides a possible direction for the study of reciprocal behaviors. PMID:22216202

  5. Repeated thinking promotes cooperation in spatial prisoner's dilemma game

    Inspired by the realistic process of taking decisions in social life, we have proposed a repeated thinking mechanism in the evolutionary spatial prisoner's dilemma game where players are denoted by the vertices and play games with their direct neighbors. Under our mechanism, a player i will randomly select a neighbor j and then deliberate for M times before strategy updating. It will remain unchanged if not all M considerations suggest it to learn the strategy of j. We mainly focus on the evolution of cooperation in the systems. Interestingly, we find that the cooperation level fC is remarkably promoted and fC has a monotonic dependence on the caution parameter M, indicating that being cautious facilitates the emergence and persistence of cooperation. We give a simple but clear explanation for this cooperation promotion via detecting the cooperator-defector transition process. Moreover, the robustness of this mechanism is also examined on different noise levels and game models.

    The collective influence on the individuals' behavior have attracted much attention, and interesting phenomena such as social facilitation and social loafing have been studied. In this paper, we consider how the collective influence affects the evolution of cooperation in a structured population of individuals who nourish and benefit from public goods in groups. Individuals are supposed to distribute endowments to different groups to nourish the corresponding public goods. The collective influence is indicated by a tunable parameter α, with larger α corresponding to the players' higher preference to contribute more to the larger groups, which is similar to the social-facilitation effect in the real world, whereas, with smaller α corresponding to individuals' contrary preference, i.e., the social-loafing effect. Interestingly, we find that the heterogeneity of public-goods setting favors cooperation. Furthermore, the system where social loafing occurs performs better than that with social facilitation, in the case of heterogeneous formation.

  19. Promotion of cooperation by payoff-driven migration

    NASA Astrophysics Data System (ADS)

    Chen, Ya-Shan; Yang, Han-Xin; Guo, Wen-Zhong

    2016-05-01

    Migration plays an important role in the evolution of cooperation. Previous studies concerning mobile population often assumed that all agents move with the identical velocity. In this paper, we propose a payoff-driven migration in which the velocity of an agent depends on his/her payoff. A parameter α is introduced to adjust the influence of payoff, when α = 0 means that agents all move with the identical velocity while α > 0 means that the lower the payoff is, the faster the moving speed is, and vice versa. For the prisoner's dilemma game, we find that in comparison with the case that agents all move with the same speed, cooperation could be promoted strongly when payoff-dependent velocity is considered. Remarkably, the cooperation level is not a monotonic function of α, and there exists an optimal value of α which can lead to the maximum cooperation level. For the snowdrift game, the cooperation level increases with α.

    Today, cardiovascular disease is the principal cause of death and hospitalization in Spain, and accounts for an annual healthcare budget of more than 4000 million euros. Consequently, early diagnosis, effective prevention, and the optimum treatment of cardiovascular disease present a significant social and healthcare challenge for the country. In this context, combining all available resources to increase the efficacy and healthcare benefits of scientific research is a priority. This rationale prompted the establishment of the Spanish Cooperative Cardiovascular Disease Research Network, or RECAVA (Red Temática de Investigación Cooperativa en Enfermedades Cardiovasculares), 5 years ago. Since its foundation, RECAVA's activities have focused on achieving four objectives: a) to facilitate contacts between basic, clinical and epidemiological researchers; b) to promote the shared use of advanced technological facilities; c) to apply research results to clinical practice, and d) to train a new generation of translational cardiovascular researchers in Spain. At present, RECAVA consists of 41 research groups and seven shared technological facilities. RECAVA's research strategy is based on a scientific design matrix centered on the most important cardiovascular processes. The level of RECAVA's research activity is reflected in the fact that 28 co-authored articles were published in international journals during the first six months of 2007, with each involving contributions from at least two groups in the network. Finally, RECAVA also participates in the work of the Spanish National Center for Cardiovascular Research, or CNIC (Centro Nacional de Investigación Cardiovascular), and some established Biomedical Research Network Centers, or CIBER (Centros de Investigación Biomédica en RED), with the aim of consolidating the development of a dynamic multidisciplinary research framework that is capable of meeting the growing challenge that cardiovascular disease will present

  3. Interactive diversity promotes the evolution of cooperation in structured populations

    NASA Astrophysics Data System (ADS)

    2016-10-01

    Evolutionary games on networks traditionally assume that each individual adopts an identical strategy to interact with all its neighbors in each generation. Considering the prevalent diversity of individual interactions in the real society, here we propose the concept of interactive diversity, which allows individuals to adopt different strategies against different neighbors in each generation. We investigate the evolution of cooperation based on the edge dynamics rather than the traditional nodal dynamics in networked systems. The results show that, without invoking any other mechanisms, interactive diversity drives the frequency of cooperation to a high level for a wide range of parameters in both well-mixed and structured populations. Even in highly connected populations, cooperation still thrives. When interactive diversity and large topological heterogeneity are combined together, however, in the relaxed social dilemma, cooperation level is lower than that with just one of them, implying that the combination of many promotive factors may make a worse outcome. By an analytical approximation, we get the condition under which interactive diversity provides more advantages for cooperation than traditional evolutionary dynamics does. Numerical simulations validating the approximation are also presented. Our work provides a new line to explore the latent relation between the ubiquitous cooperation and individuals’ distinct responses in different interactions. The presented results suggest that interactive diversity should receive more attention in pursuing mechanisms fostering cooperation.

    In prisoner's dilemma game (shortly, PD game), punishment is most frequently used to promote cooperation. However, outcome varies when different punishment approaches are applied. Here the PD game is studied on a square lattice when different punishment patterns are adopted. As is known to all, tax system, a common tool to adjust the temperature of the economy, is widely used in human society. Inspired by this philosophy, players in this study would pay corresponding taxes in accordance with their payoff level. In this way, public benefit fund is established consequently and it would be utilized to punish defectors. There are two main methods for punishing: slight intensity of punishment (shortly, SLP) and severe intensity of punishment (shortly, SEP). When the totaling of public benefit fund keeps relatively fixed, SLP extends further, which means more defectors would be punished; by contrast, SEP has a smaller coverage. It is of interest to verify whether these two measures can promote cooperation and which one is more efficient. Simulate results reveal that both of them can promote cooperation remarkably. Specifically speaking, SLP shows constant advantage from the point of view either of fractions of cooperation or average payoff. PMID:25137051

  9. Simulating social dilemmas: promoting cooperative behavior through imagined group discussion.

    Meleady, Rose; Hopthrow, Tim; Crisp, Richard J

    2013-05-01

    A robust finding in social dilemmas research is that individual group members are more likely to act cooperatively if they are given the chance to discuss the dilemma with one another. The authors investigated whether imagining a group discussion may represent an effective means of increasing cooperative behavior in the absence of the opportunity for direct negotiation among decision makers. Five experiments, utilizing a range of task variants, tested this hypothesis. Participants engaged in a guided simulation of the progressive steps required to reach a cooperative consensus within a group discussion of a social dilemma. Results support the conclusion that imagined group discussion enables conscious processes that parallel those underlying the direct group discussion and is a strategy that can effectively elicit cooperative behavior. The applied potential of imagined group discussion techniques to encourage more socially responsible behavior is discussed.

  10. Gossip Versus Punishment: The Efficiency of Reputation to Promote and Maintain Cooperation

    Prior theory suggests that reputation spreading (e.g., gossip) and punishment are two key mechanisms to promote cooperation in groups, but no behavioral research has yet examined their relative effectiveness and efficiency in promoting and maintaining cooperation. To examine these issues, we observed participants interacting in a four-round public goods game (PGG) with or without gossip and punishment options, and a subsequent two-round trust game (TG). We manipulated gossip as the option to send notes about other group members to these members’ future partners, and punishment as the option to assign deduction points to reduce other group members’ outcomes with a fee-to-fine ratio of 1:3. Findings revealed that in the four-round PGG, the option to gossip increased both cooperation and individual earnings, whereas the option to punish had no overall effect on cooperation (but a positive effect on cooperation in the last two rounds of the PGG) and significantly decreased individual earnings. Importantly, the initial option to gossip made people more trusting and trustworthy in the subsequent TG when gossip was no longer possible, compared to the no-gossip condition. Thus, we provide some initial evidence that gossip may be more effective and efficient than punishment to promote and maintain cooperation. PMID:27039896

  15. The glycocalyx promotes cooperative binding and clustering of adhesion receptors.

    2016-05-18

    Cell adhesion plays a pivotal role in various biological processes, e.g., immune responses, cancer metastasis, and stem cell differentiation. The adhesion behaviors depend subtly on the binding kinetics of receptors and ligands restricted at the cell-substrate interfaces. Although much effort has been directed toward investigating the kinetics of adhesion molecules, the role of the glycocalyx, anchored on cell surfaces as an exterior layer, is still unclear. In this paper, we propose a theoretical approach to study the collective binding kinetics of a few and a large number of binders in the presence of the glycocalyx, representing the cases of initial and mature adhesions of cells, respectively. The analytical results are validated by finding good agreement with our Monte Carlo simulations. In the force loading case, the on-rate and affinity increase as more bonds form, whereas this cooperative effect is not observed in the displacement loading case. The increased thickness and stiffness of the glycocalyx tend to decrease the affinity for a few bonds, while they have less influence on the affinity for a large number of bonds. Moreover, for a flexible membrane with thermally-excited shape fluctuations, the glycocalyx is exhibited to promote the formation of bond clusters, mainly due to the cooperative binding of binders. This study helps to understand the cooperative kinetics of adhesion receptors under physiologically relevant loading conditions and sheds light on the novel role of the glycocalyx in cell adhesion.

    A new European Polar Framework agreement aims to increase research cooperation, streamline links between many European national research programs in the Arctic and Antarctic, and possibly create international research teams similar to the Integrated Ocean Drilling Program. The new framework includes commitments to collaborate on new multinational research initiatives and to have national polar programs converge where appropriate. “Recent environmental shifts in the poles have been large and rapid. By linking together Europe's polar research more closely we can get a better grasp on the wide-ranging series of changes taking place,” said Paul Egerton, executive director of the European Science Foundation's European Polar Board, which aims to facilitate cooperation among various organizations. The agreement was signed on 24 June by 26 European scientific institutions, including the British Antarctic Survey; the Agency of Culture, Education, Research and the Church Affairs, Greenland; the Alfred-Wegener-Institut für Polar- und Meeresforschung, Germany; Italy's Programma Nazionale di Ricerche in Antartide; Norway's Norsk Polarinstitutt; and the Romanian Antarctic Foundation.

    The US Environmental Protection Agency (EPA) and the private sector find an increasing need for new cost-effective environmental technologies to treat, control, and prevent pollution. Many cooperative research programs to address this concern are available through the EPA. The Office of Research and Development (ORD) currently operates two of the most visible innovative technology development programs: (1) Superfund Innovative Technology Evaluation (SITE) Program; (2) Federal Technology Transfer Act (FTTA) Program. These programs work very closely with the other EPA program offices. A brief overview of these activities and the new Environmental Technology Initiative within EPA are presented in this paper.

    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

    The joint venture of many members is common both in animal world and human society. In these public enterprizes, highly cooperative groups are more likely to while low cooperative groups are still possible but not probable to succeed. Existent literature mostly focuses on the traditional public goods game, in which cooperators create public wealth unconditionally and benefit all group members unbiasedly. We here institute a model addressing this public goods dilemma with incorporating the public resource foraging failure risk. Risk-averse individuals tend to lead a autarkic life, while risk-preferential ones tend to participate in the risky public goods game. For participants, group's success relies on its cooperativeness, with increasing contribution leading to increasing success likelihood. We introduce a function with one tunable parameter to describe the risk removal pattern and study in detail three representative classes. Analytical results show that the widely replicated population dynamics of cyclical dominance of loner, cooperator and defector disappear, while most of the time loners act as savors while eventually they also disappear. Depending on the way that group's success relies on its cooperativeness, either cooperators pervade the entire population or they coexist with defectors. Even in the later case, cooperators still hold salient superiority in number as some defectors also survive by parasitizing. The harder the joint venture succeeds, the higher level of cooperation once cooperators can win the evolutionary race. Our work may enrich the literature concerning the risky public goods games.

  9. Shape matters: Lifecycle of cooperative patches promotes cooperation in bulky populations

    PubMed Central

    2015-01-01

    Natural cooperative systems take many forms, ranging from one-dimensional cyanobacteria arrays to fractal-like biofilms. We use in silico experimental systems to study a previously overlooked factor in the evolution of cooperation, physical shape of the population. We compare the emergence and maintenance of cooperation in populations of digital organisms that inhabit bulky (100 × 100 cells) or slender (4 × 2500) toroidal grids. Although more isolated subpopulations of secretors in a slender population could be expected to favor cooperation, we find the opposite: secretion evolves to higher levels in bulky populations. We identify the mechanistic explanation for the shape effect by analyzing the lifecycle and dynamics of cooperator patches, from their emergence and growth, to invasion by noncooperators and extinction. Because they are constrained by the population shape, the cooperator patches expand less in slender than in bulky populations, leading to fewer cooperators, less public good secretion, and generally lower cooperation. The patch dynamics and mechanisms of shape effect are robust across several digital cooperation systems and independent of the underlying basis for cooperation (public good secretion or a cooperation game). Our results urge for a greater consideration of population shape in the study of the evolution of cooperation across experimental and modeling systems. PMID:25639379

    Cooperation among genetically unrelated individuals can be supported by direct reciprocity. Theoretical models and experiments with adults show that the possibility of future interactions with the same partner can promote cooperation via conditionally cooperative strategies such as tit-for-tat (TFT). Here, we introduce a novel implementation of the repeated Prisoner's Dilemma (PD) designed for children to examine whether repeated interactions can successfully promote cooperation in 10 and 11 year olds. We find that children cooperate substantially more in repeated PDs than in one-shot PDs. We also find that girls cooperate more than boys, and that children with more conduct problems cooperate less. Finally, we find that children use conditional cooperation strategies but that these strategies vary by gender and conduct problem rating. Specifically, girls and children with few conduct problems appear to follow an altruistic version of win-stay, lose-shift (WSLS), attempting to re-establish cooperation after they had defected. Boys and children with more conduct problems appear to follow a Grim strategy, defecting for the duration after the partner defects. Thus we provide evidence that children utilize the power of direct reciprocity to promote cooperation in strategic interactions and that, by late elementary school, distinct strategies of conditional cooperation have emerged.

  13. Distinguishing the opponents promotes cooperation in well-mixed populations

    NASA Astrophysics Data System (ADS)

    Wardil, Lucas; da Silva, Jafferson K. L.

    2010-03-01

    Cooperation has been widely studied when an individual strategy is adopted against all coplayers. In this context, some extra mechanisms, such as punishment, reward, memory, and network reciprocity must be introduced in order to keep cooperators alive. Here, we adopt a different point of view. We study the adoption of different strategies against different opponents instead of adoption of the same strategy against all of them. In the context of the prisoner dilemma, we consider an evolutionary process in which strategies that provide more benefits are imitated and the players replace the strategy used in one of the interactions furnishing the worst payoff. Individuals are set in a well-mixed population, so that network reciprocity effect is excluded and both synchronous and asynchronous updates are analyzed. As a consequence of the replacement rule, we show that mutual cooperation is never destroyed and the initial fraction of mutual cooperation is a lower bound for the level of cooperation. We show by simulation and mean-field analysis that (i) cooperation dominates for synchronous update and (ii) only the initial mutual cooperation is maintained for asynchronous update. As a side effect of the replacement rule, an “implicit punishment” mechanism comes up in a way that exploitations are always neutralized providing evolutionary stability for cooperation.

    The forming of human social ties tends to be with similar individuals. This study concentrates on the emergence of cooperation among heterogeneous populations. A simple model is proposed by considering the impact of interplay between the evolution of strategies and that of social partnerships on cooperation dynamics. Whenever two individuals acquire the rewards by playing prisoner's dilemma game with each other, the friendship (friendship is quantified as the weight of a link) between the two individuals deepens. Individuals can switch off the social ties with the partners who are unfriendly and rewire to similar new ones. Under this partner switching mechanism, population structure is divided into several groups and cooperation can prevail. It is observed that the frequent tendency of partner switching can lead to the enhancement of cooperative behavior under the enormous temptation to defect. Moreover, the influence of discounting the relationship between different individuals is also investigated. Meanwhile, the cooperation prevails when the adjustment of friendships mainly depends on the incomes of selected individuals rather than that of their partners. Finally, it is found that too similar population fail to maximize the cooperation and there exists a moderate similarity that can optimize cooperation.

    Evolutionary games can model dilemmas for which cooperation can exist in rational populations. According to intuition, memory of the history can help individuals to overcome the dilemma and increase cooperation. However, here we show that no such general predictions can be made for dilemma games with memory. Agents play repeated prisoner’s dilemma, snowdrift, or stag hunt games in well-mixed populations or on a lattice. We compare the cooperation ratio and fitness for systems with or without memory. An interesting result is that cooperation is demoted in snowdrift and stag hunt games with memory when cost-to-benefit ratio is low, while system fitness still increases with memory in the snowdrift game. To illustrate this interesting phenomenon, two further experiments were performed to study R, ST, and P reciprocity and investigate 16 agent strategies for one-step memory. The results show that memory plays different roles in different dilemma games.

  16. Cooperators Unite! Assortative linking promotes cooperation particularly for medium sized associations

    PubMed Central

    2010-01-01

    Background Evolution of cooperative behaviour is widely studied in different models where interaction is heterogeneous, although static among individuals. However, in nature individuals can often recognize each other and chose, besides to cooperate or not, to preferentially associate with or to avoid certain individuals. Here we consider a dynamical interaction graph, in contrast to a static one. We propose several rules of rejecting unwanted partners and seeking out new ones, and study the probability of emergence and maintenance of cooperation on these dynamic networks. Results Our simulations reveal that cooperation can evolve and be stable in the population if we introduce preferential linking, even if defectors can perform it too. The fixation of cooperation has higher probability than that of on static graphs, and this effect is more prevalent at high benefit to cost ratios. We also find an optimal number of partners, for which the fixation probability of cooperation shows a maximum. Conclusions The ability to recognize, seek out or avoid interaction partners based on the outcome of past interactions has an important effect on the emergence of cooperation. Observations about the number of partners in natural cooperating groups are in concordance with the result of our model. PMID:20540710

  17. Expectation-driven migration promotes cooperation by group interactions

    NASA Astrophysics Data System (ADS)

    2012-06-01

    “Voting with feet” describes the prominent social phenomenon that people tend to move away from deteriorating neighborhoods and search for and join prosperous groups. To quantify the role this kind of expectation-driven migration plays in the evolution of cooperation, here we study a simple yet effective model of cooperation based on spatial public goods games. The population structure is characterized by a square lattice with some nodes being left empty. Individuals have expectations toward their current habitats. Dissatisfied players, whose expectation is not met after interacting with all directly connected neighbors, tend to abstain from the groups of low quality by moving away and explore the physical niches of avail. How fast interaction happens relatively to selection is regulated by the time-scale ratio of game interaction to natural selection. Under strong selection, simulation results show that cooperation is greatly improved for either low, moderate, or high expectations compared to whenever the expectation-driven migration is absent. Further explorations reveal that neither too high nor too low but rather a combination of moderate expectations and rapid interaction establishes cooperation for a moderate public goods enhancement factor. There exists an optimal interval of expectation level most favoring the evolution of cooperation as the required time-scale ratio is minimized.

  18. Heterogeneous Coupling between Interdependent Lattices Promotes the Cooperation in the Prisoner's Dilemma Game.

    PubMed

    Xia, Cheng-Yi; Meng, Xiao-Kun; Wang, Zhen

    2015-01-01

    In the research realm of game theory, interdependent networks have extended the content of spatial reciprocity, which needs the suitable coupling between networks. However, thus far, the vast majority of existing works just assume that the coupling strength between networks is symmetric. This hypothesis, to some extent, seems inconsistent with the ubiquitous observation of heterogeneity. Here, we study how the heterogeneous coupling strength, which characterizes the interdependency of utility between corresponding players of both networks, affects the evolution of cooperation in the prisoner's dilemma game with two types of coupling schemes (symmetric and asymmetric ones). Compared with the traditional case, we show that heterogeneous coupling greatly promotes the collective cooperation. The symmetric scheme seems much better than the asymmetric case. Moreover, the role of varying amplitude of coupling strength is also studied on these two interdependent ways. Current findings are helpful for us to understand the evolution of cooperation within many real-world systems, in particular for the interconnected and interrelated systems. PMID:26102082

  19. Scarcity may promote cooperation in populations of simple agents

    In the study of the evolution of cooperation, resource limitations are usually assumed just to provide a finite population size. Recently, however, it has been pointed out that resource limitation may also generate dynamical payoffs able to modify the original structure of the games. Here we study analytically a phase transition from a homogeneous population of defectors when resources are abundant to the survival of unconditional cooperators when resources reduce below a threshold. To this end, we introduce a model of simple agents, with no memory or ability of recognition, interacting in well-mixed populations. The result might shed light on the role played by resource constraints on the origin of multicellularity.

  2. First carrot, then stick: how the adaptive hybridization of incentives promotes cooperation

    Social institutions often use rewards and penalties to promote cooperation. Providing incentives tends to be costly, so it is important to find effective and efficient policies for the combined use of rewards and penalties. Most studies of cooperation, however, have addressed rewarding and punishing in isolation and have focused on peer-to-peer sanctioning as opposed to institutional sanctioning. Here, we demonstrate that an institutional sanctioning policy we call ‘first carrot, then stick’ is unexpectedly successful in promoting cooperation. The policy switches the incentive from rewarding to punishing when the frequency of cooperators exceeds a threshold. We find that this policy establishes and recovers full cooperation at lower cost and under a wider range of conditions than either rewards or penalties alone, in both well-mixed and spatial populations. In particular, the spatial dynamics of cooperation make it evident how punishment acts as a ‘booster stage’ that capitalizes on and amplifies the pro-social effects of rewarding. Together, our results show that the adaptive hybridization of incentives offers the ‘best of both worlds’ by combining the effectiveness of rewarding in establishing cooperation with the effectiveness of punishing in recovering it, thereby providing a surprisingly inexpensive and widely applicable method of promoting cooperation.

  5. Punishment does not promote cooperation under exploration dynamics when anti-social punishment is possible.

    It has been argued that punishment promotes the evolution of cooperation when mutation rates are high (i.e. when agents engage in 'exploration dynamics'). Mutations maintain a steady supply of agents that punish free-riders, and thus free-riders are at a disadvantage. Recent experiments, however, have demonstrated that free-riders sometimes also pay to punish cooperators. Inspired by these empirical results, theoretical work has explored evolutionary dynamics where mutants are rare, and found that punishment does not promote the evolution of cooperation when this 'anti-social punishment' is allowed. Here we extend previous theory by studying the effect of anti-social punishment on the evolution of cooperation across higher mutation rates, and by studying voluntary as well as compulsory Public Goods Games. We find that for intermediate and high mutation rates, adding punishment does not promote cooperation in either compulsory or voluntary public goods games if anti-social punishment is possible. This is because mutations generate agents that punish cooperators just as frequently as agents that punish defectors, and these two effects cancel each other out. These results raise questions about the effectiveness of punishment for promoting cooperation when mutations are common, and highlight how decisions about which strategies to include in the strategy set can have profound effects on the resulting dynamics.

  8. Cautious strategy update promotes cooperation in spatial prisoner’s dilemma game

    In the realistic world, individual cautiousness can be often involved or observed when a rational individual makes a decision. However, it remains unclear how such individual cautiousness influences the evolution of cooperative behavior. To this end, we consider a Fermi strategy updating rule, where each individual is assigned a cautiousness index that controls its learning activity, and then study the evolution of cooperation in the spatial prisoner’s dilemma game. Interestingly, it is found that cooperation can be significantly promoted when individuals’ cautiousness is considered. In particular, there exists an optimal range of the degree of cautiousness resulting in the highest cooperation level. The remarkable promotion of cooperation, as well as the emerging phase transition is explained by configurational analysis. The sensitivity of cooperation to initial states with different fractions of cooperators is also discussed. The result illustrates that high densities of cooperators can be established at small initial fractions of cooperators. The detailed mechanism for such phenomenon is explained by analyzing the typical initial configurations.

  10. Promotion of Cooperation in a Spatial Public Goods Game with Long Range Learning and Mobility

    NASA Astrophysics Data System (ADS)

    Xiao, Yao; Hua, Da-Yin

    2012-11-01

    We studied the effect of population density in a spatial public goods game. We found that the effect on the evolution of cooperation is very complex when the strategy learning and mobility of players in a long range are considered in a two-dimensional lattice. As the learning range is larger than the mobility range, the system is driven to enter into a cooperation state for a low population density, because a small local group is beneficial to sustain a high level of cooperation. As population density increases to a moderate range, the mobility of players from a domain invaded by defectors supports the evolution stability of cooperation. When the mobility range is larger than the learning range, a formation of compact domains of cooperators promotes cooperation as the population density becomes high.

    This article describes a positive experience in building Arab and Israeli cooperation through health initiatives. Over the past 10 years Israeli, Jordanian, and Palestinian health professionals have worked together through the Canada International Scientific Exchange Program (CISEPO). In the initial project, nearly 17,000 Arab and Israeli newborn babies were tested for early detection of hearing loss, an important health issue for the region. The network has grown to address additional needs, including mother-child health, nutrition, infectious diseases, and youth health. Our guiding model emphasises two goals: project-specific outcomes in health improvement, and broader effects on cross-border cooperation. Lessons learned from this experience and the model provide direction for ways that health professionals can contribute to peacebuilding. PMID:15811462

  13. Population heterogeneity promotes a preference for blind cooperation

    NASA Astrophysics Data System (ADS)

    Perez-Escudero, Alfonso; Friedman, Jonathan; Gore, Jeff

    Game theory--and common sense--recommend to carefully weigh costs and benefits before deciding on a course of action. Yet we often disapprove of people who do so, even when their actual decision benefits us. For example, we prefer people who directly agree to do us a favor over those who agree only after securing enough information to ensure that the favor will not be too costly. Why should we care about how people make their decisions, rather than just focus on the decisions themselves? Hoffman et al. (2015) have shown that such aversion to information gathering may be beneficial when it is strong enough to increase the level of cooperation. Here we show that the same type of aversion arises in heterogeneous populations, but for a different reason: individuals who seek additional information may reveal themselves to be undesirable partners, since they are less likely to cooperate in the future when conditions change. Aversion to information gathering thus facilitates preferential interactions with blind cooperators, who are more favorable partners. Due to this new mechanism the prevalence of such aversion rapidly increases with population diversity, because partner discrimination is more useful in populations which harbor partners of a more varied quality.

  14. Partner choice promotes cooperation: the two faces of testing with agent-based models.

    PubMed

    2014-03-01

    Reciprocity is one of the most debated among the mechanisms that have been proposed to explain the evolution of cooperation. While a distinction can be made between two general processes that can underlie reciprocation (within-pair temporal relations between cooperative events, and partner choice based on benefits received), theoretical modelling has concentrated on the former, while the latter has been often neglected. We developed a set of agent-based models in which agents adopted a strategy of obligate cooperation and partner choice based on benefits received. Our models tested the ability of partner choice both to reproduce significant emergent features of cooperation in group living animals and to promote the evolution of cooperation. Populations formed by agents adopting a strategy of obligate cooperation and partner choice based on benefits received showed differentiated "social relationships" and a positive correlation between cooperation given and received, two common phenomena in animal cooperation. When selection across multiple generations was added to the model, agents adopting a strategy of partner choice based on benefits received outperformed selfish agents that did not cooperate. Our results suggest partner choice is a significant aspect of cooperation and provides a possible mechanism for its evolution.

  16. The role of institutional incentives and the exemplar in promoting cooperation.

    PubMed

    Wu, Jia-Jia; Li, Cong; Zhang, Bo-Yu; Cressman, Ross; Tao, Yi

    2014-01-01

    People on average do not play their individually rational Nash equilibrium (NE) strategy in game experiments based on the public goods game (PGG) that model social dilemmas. Differences from NE behavior have also been observed in PGG experiments that include incentives to cooperate, especially when these are peer-incentives administered by the players themselves. In our repeated PGG experiment, an institution rewards and punishes individuals based on their contributions. The primary experimental result is that institutions which both reward and punish (IRP) promote cooperation significantly better than either institutions which only punish (IP) or which only reward (IR), and that IP has contribution levels significantly above IR. Although comparing their single-round NE strategies correctly predicts which incentives are best at promoting cooperation, individuals do not play these strategies overall. Our analysis shows that other intrinsic motivations that combine conforming behavior with reactions to being rewarded/punished provide a better explanation of observed outcomes. In our experiments, some individuals who display more cooperation than other individuals can be regarded as the exemplars (or leaders). The role of these exemplars in promoting cooperation provides important insights into understanding cooperation in PGG and the effectiveness of institutional incentives at promoting desirable societal behavior.

  1. Promotion of cooperation in social dilemma games via generalised indirect reciprocity

    NASA Astrophysics Data System (ADS)

    Chiong, Raymond; Kirley, Michael

    2015-10-01

    This paper presents a novel generalised indirect reciprocity approach for promoting cooperation in social dilemma games. Here, players decide upon an action to play in the game based on public information (or "external cues") rather than individual-specific information. The public information is constantly updated according to the underlying learning model. Comprehensive simulation experiments using the N-player Prisoner's Dilemma (PD) and Snowdrift (SD) games show that generalised indirect reciprocity promotes high levels of cooperation across a wide range of conditions. This is despite the fact that the make-up of player groups is continually changing. As expected, the extent of cooperative behaviour observed in the "constraint-relaxed" N-player SD game is significantly higher than the N-player PD game. Our proposed generalised indirect reciprocity model may shed light on the conundrum of cooperation between anonymous individuals.

  2. Older partner selection promotes the prevalence of cooperation in evolutionary games.

    2014-10-21

    Evolutionary games typically come with the interplays between evolution of individual strategy and adaptation to network structure. How these dynamics in the co-evolution promote (or obstruct) the cooperation is regarded as an important topic in social, economic, and biological fields. Combining spatial selection with partner choice, the focus of this paper is to identify which neighbour should be selected as a role to imitate during the process of co-evolution. Age, an internal attribute and kind of local piece of information regarding the survivability of the agent, is a significant consideration for the selection strategy. The analysis and simulations presented, demonstrate that older partner selection for strategy imitation could foster the evolution of cooperation. The younger partner selection, however, may decrease the level of cooperation. Our model highlights the importance of agent׳s age on the promotion of cooperation in evolutionary games, both efficiently and effectively. PMID:24956329

    Koelen, M; Vaandrager, L; Colomer, C

    2001-01-01

    OBJECTIVE—To analyse dilemmas and challenges in health promotion research, and to generate ideas for future development.
METHOD—The analysis is based on authors' experiences in working in the field of research and action in health promotion and on experiences of others as found in literature.
RESULTS—The assumptions underlying scientific research as based in the biomedical design are difficult to meet in community-based health promotion research. Dilemmas are identified in relation to the possibility of defining the independent and dependent variables beforehand and the intermingling of these variables (the intervention and outcome dilemma), the difficulty in quantifying the desired outcomes (the number dilemma), and the problem of diffusion of the programme to the control group (the control group dilemma).
CONCLUSION—Research in health promotion has specific reasons to reconsider the approach towards research, the selection of outcome variables, and research techniques. Strategies and methods to make activities and their outcomes clear are discussed and criteria to judge confidence and applicability of research findings are presented.

  7. Collective punishment is more effective than collective reward for promoting cooperation

    2015-01-01

    Collective punishment and reward are usually regarded as two potential mechanisms to explain the evolution of cooperation. Both scenarios, however, seem problematic to understand cooperative behavior, because they can raise the second-order free-rider problem and many organisms are not able to discriminate less cooperating individuals. Even though they have been proved to increase cooperation, there has been a debate about which one being more effective. To address this issue, we resort to the N-player evolutionary snowdrift game (NESG), where a collective punishment/reward mechanism is added by allowing some players to display punishment/reward towards all remaining players. By means of numerous simulations and analyses, we find that collective punishment is more effective in promoting cooperation for a relatively high initial frequency of cooperation or for a relatively small group. When the intensity of punishment exceeds a certain threshold, a stable state of full cooperation emerges for both small and large groups. In contrast, such state does not appear for large groups playing a NESG with reward mechanism. In the case of mutualistic interactions, finally, our results show the new payoff with collective punishment/reward can lead to the coexistence of cooperators and defectors when discrimination between these two is not possible.

  1. Using research poetics "responsibly": applications for health promotion research.

    Nichols, Tracy R; Biederman, Donna J; Gringle, Meredith R

    2014-01-01

    Research poetics, a form of arts-based research methods, has been under-utilized in the field of health promotion. Poetic methods have most commonly been used as a form of re/presentation of the lived experience in qualitative research. For the community-engaged researcher, re/presenting findings through poetry offers unique opportunities for engaging the reader and reaching diverse communities. However, this approach also has implications as an analytic method and allows the analyst to have a more meaningful and personal engagement with participants' stories. Perhaps most importantly, this approach acknowledges and brings to the forefront the co-construction of qualitative findings and de-centers the authority of the researcher by preserving and promoting the participant's voice. Using examples from the authors' own research, this article describes opportunities for incorporating research poetics into health promotion research and argues for its applicability for community-engaged health promotion researchers.

    The research project `Moon Mapping' has been established in 2014 between the Italian and Chinese Governments to promote cooperation and exchange between undergraduate students from both countries. The operational phase of the project started in early 2015, and will end in 2017, for a total length of three years. The main aim is to train new scholars to be able to work on different kinds of remotely-sensed data collected over the Moon surface by the Chinese space missions Chang'E-1/2. The project coordination has been assigned to the Italian Space Agency for the Italian side and to the Center of Space Exploration, China Ministry of Education, for the Chinese side. Several Chinese universities and Italian national research institutes and universities have been officially involved in this project. Six main research topics have been identified: (1) map of the solar wind ion; (2) geomorphological map of the Moon; (3) data preprocessing of Chang'E-1 mission; (4) map of element distribution; (5) establishment of 3D digital visualization system; and (6) compilation and publication of a tutorial on joint lunar mapping.

  3. Diverse strategy-learning styles promote cooperation in evolutionary spatial prisoner's dilemma game

    2015-11-01

    Observational learning and practice learning are two important learning styles and play important roles in our information acquisition. In this paper, we study a spacial evolutionary prisoner's dilemma game, where players can choose the observational learning rule or the practice learning rule when updating their strategies. In the proposed model, we use a parameter p controlling the preference of players choosing the observational learning rule, and found that there exists an optimal value of p leading to the highest cooperation level, which indicates that the cooperation can be promoted by these two learning rules collaboratively and one single learning rule is not favor the promotion of cooperation. By analysing the dynamical behavior of the system, we find that the observational learning rule can make the players residing on cooperative clusters more easily realize the bad sequence of mutual defection. However, a too high observational learning probability suppresses the players to form compact cooperative clusters. Our results highlight the importance of a strategy-updating rule, more importantly, the observational learning rule in the evolutionary cooperation.

    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.

    A model of stochastic evolutionary game dynamics with finite population of size N +M was built. Among these individuals, N individuals update strategies with aspiration updating, while the other M individuals update strategies with imitation updating. In the proposed model, we obtain the expression of the mean fraction of cooperators and analyze some concrete cases. Compared with the standard imitation dynamics, there is always a positive probability to support the formation of cooperation in the system with the aspiration and imitation rules. Moreover, the numerical results indicate that more aspiration-driven individuals lead to a higher mean fraction of imitation-driven cooperators, which means the invasion of the aspiration-driven individuals is conducive to promoting the cooperation of the imitation-driven individuals.

  7. Investment and Return in International Space Life Sciences Research Cooperation

    McPhee, Jancy C.; White, Ronald J.

    2007-01-01

    Today, a worldwide community of life scientists interested in space research is attempting to improve the understanding of general biological processes, aid the development of procedures to reduce the biomedically-related risks of space flight, and/or directly support the health care of people who fly in space. Unfortunately, limited resource and subject availability and the technical challenges of performing space experiments have all hampered the full growth and development of space life sciences research. For many years, international cooperation in this field has been considered an attractive approach towards overcoming some of these difficulties, since pooling resources and sharing results would enhance the knowledge of all cooperating partners. International cooperative activities, however, require an investment by each partner and, just as in many other endeavors, the research gain can be directly related to the investment made. In this paper, the authors will discuss three possible levels of cooperation: sharing of data from independent investigations, harmonious integration of pre-designed independent investigations, and de novo design of an integrated suite of investigations using a joint investigator team. The degree of investment and potential return for each level of cooperation will be described.

  18. Promoting research integrity in the geosciences

    Mayer, Tony

    2015-04-01

    Conducting research in a responsible manner in compliance with codes of research integrity is essential. The geosciences, as with all other areas of research endeavour, has its fair share of misconduct cases and causes celebres. As research becomes more global, more collaborative and more cross-disciplinary, the need for all concerned to work to the same high standards becomes imperative. Modern technology makes it far easier to 'cut and paste', to use Photoshop to manipulate imagery to falsify results at the same time as making research easier and more meaningful. So we need to promote the highest standards of research integrity and the responsible conduct of research. While ultimately, responsibility for misconduct rests with the individual, institutions and the academic research system have to take steps to alleviate the pressure on researchers and promote good practice through training programmes and mentoring. The role of the World Conferences on Research Integrity in promoting the importance of research integrity and statements about good practice will be presented and the need for training and mentoring programmes will be discussed

  19. Promotion of cooperation induced by discriminators in the spatial multi-player donor-recipient game

    2016-11-01

    Although the two-player donor-recipient game has been used extensively in studying cooperation in social dilemmas, the scenario in which a donor can simultaneously donate resources to multiple recipients is also common in human societies, economic systems, and social networks. This paper formulates a model of the multi-player donor-recipient game considering a multi-recipient scenario. The promotion of cooperation is also studied by introducing a discriminative cooperation strategy into the game, which donates resources to recipients in proportion to their previous donations with a cost for the collection of information. The evolutionary dynamics of individual strategies are explored in homogeneous and heterogeneous scenarios by leveraging spatial evolutionary game theory. The results show that in a homogeneous scenario, defectors can dominate the network at the equilibrium state only when the cost-to-benefit ratio (R) of donated resources is large. In a heterogeneous scenario, three strategies can coexist all the time within the range of R that was studied, and the promotion of cooperation is more effective when the values of R are smaller. Results from a single node evolution and the formation of local patterns of interaction are provided, and it is analytically shown that discriminators can maintain fairness in resource donation and guarantee long-term cooperation when R is not too large.

The development of KBIS is described.

  2. Molecular crowders and cosolutes promote folding cooperativity of RNA under physiological ionic conditions.

    2014-03-01

    Folding mechanisms of functional RNAs under idealized in vitro conditions of dilute solution and high ionic strength have been well studied. Comparatively little is known, however, about mechanisms for folding of RNA in vivo where Mg(2+) ion concentrations are low, K(+) concentrations are modest, and concentrations of macromolecular crowders and low-molecular-weight cosolutes are high. Herein, we apply a combination of biophysical and structure mapping techniques to tRNA to elucidate thermodynamic and functional principles that govern RNA folding under in vivo-like conditions. We show by thermal denaturation and SHAPE studies that tRNA folding cooperativity increases in physiologically low concentrations of Mg(2+) (0.5-2 mM) and K(+) (140 mM) if the solution is supplemented with physiological amounts (∼ 20%) of a water-soluble neutral macromolecular crowding agent such as PEG or dextran. Low-molecular-weight cosolutes show varying effects on tRNA folding cooperativity, increasing or decreasing it based on the identity of the cosolute. For those additives that increase folding cooperativity, the gain is manifested in sharpened two-state-like folding transitions for full-length tRNA over its secondary structural elements. Temperature-dependent SHAPE experiments in the absence and presence of crowders and cosolutes reveal extent of cooperative folding of tRNA on a nucleotide basis and are consistent with the melting studies. Mechanistically, crowding agents appear to promote cooperativity by stabilizing tertiary structure, while those low molecular cosolutes that promote cooperativity stabilize tertiary structure and/or destabilize secondary structure. Cooperative folding of functional RNA under physiological-like conditions parallels the behavior of many proteins and has implications for cellular RNA folding kinetics and evolution.

  6. Fusing enacted and expected mimicry generates a winning strategy that promotes the evolution of cooperation.

    2013-06-18

    Although cooperation and trust are essential features for the development of prosperous populations, they also put cooperating individuals at risk for exploitation and abuse. Empirical and theoretical evidence suggests that the solution to the problem resides in the practice of mimicry and imitation, the expectation of opponent's mimicry and the reliance on similarity indices. Here we fuse the principles of enacted and expected mimicry and condition their application on two similarity indices to produce a model of mimicry and relative similarity. Testing the model in computer simulations of behavioral niches, populated with agents that enact various strategies and learning algorithms, shows how mimicry and relative similarity outperforms all the opponent strategies it was tested against, pushes noncooperative opponents toward extinction, and promotes the development of cooperative populations. The proposed model sheds light on the evolution of cooperation and provides a blueprint for intentional induction of cooperation within and among populations. It is suggested that reducing conflict intensities among human populations necessitates (i) instigation of social initiatives that increase the perception of similarity among opponents and (ii) efficient lowering of the similarity threshold of the interaction, the minimal level of similarity that makes cooperation advisable.

  7. Playing against the fittest: A simple strategy that promotes the emergence of cooperation

    NASA Astrophysics Data System (ADS)

    Brede, M.

    2011-05-01

    Understanding the emergence and sustainability of cooperation is a fundamental problem in evolutionary biology and is frequently studied in the framework of evolutionary game theory. A very powerful mechanism to promote cooperation is network reciprocity, where the interaction patterns and opportunities for strategy spread of agents are constrained to limited sets of permanent interactions partners. Cooperation survives because it is possible for close-knit communities of cooperation to be shielded from invasion by defectors. Here we show that parameter ranges in which cooperation can survive are strongly expanded if game play on networks is skewed towards more frequent interactions with more successful neighbours. In particular, if agents exclusively select neighbors for game play that are more successful than themselves, cooperation can even dominate in situations in which it would die out if interaction neighbours were chosen without a bias or with a preference for less successful opponents. We demonstrate that the "selecting fitter neighbours" strategy is evolutionarily stable. Moreover, it will emerge as the dominant strategy out of an initially random population of agents.

    Faculty and students from five universities (Kentucky, West Virginia, Utah, Pittsburgh and Auburn) are collaborating on a basic research program to develop novel C1 chemistry processes for the production of clean, high quality transportation fuel. An Industrial Advisory Board (IAB) with members from Chevron, Eastman Chemical, Energy International, Teir Associates, and the Department of Defense has been formed to provide practical guidance to the program. The program has two principal objectives. (1) Develop technology for conversion of C1 source materials (natural gas, synthesis gas, carbon dioxide and monoxide, and methanol) into clean, high efficiency transportation fuel. (2) Develop novel processes for producing hydrogen from natural gas and other hydrocarbons. Some of the principal accomplishments of the program in its first two years are: (1) The addition of acetylenic compounds in Fischer-Tropsch synthesis is found to produce significant amounts of oxygenated products in FT diesel fuels. Such oxygenated products should decrease particulate matter (PM) emissions. (2) Nanoscale, binary, Fe-based catalysts supported on alumina have been shown to have significant activity for the decomposition of methane into pure hydrogen and potentially valuable multi-walled carbon nanotubes. (3) Catalytic synthesis processes have been developed for synthesis of diethyl carbonate, higher ethers, and higher alcohols from C1 source materials. Testing of the effect of adding these oxygenates to diesel fuel on PM emissions has begun using a well-equipped small diesel engine test facility. (4) Supercritical fluid (SCF) FT synthesis has been conducted under SCF hexane using both Fe and Co catalysts. There is a marked effect on the hydrocarbon product distribution, with a shift to higher carbon number products. These and other results are summarized.

  16. Success-driven distribution of public goods promotes cooperation but preserves defection

    Established already in Biblical times, the Matthew effect refers to the fact that in societies the rich tend to get richer and the potent even more powerful. Here we investigate a game theoretical model describing the evolution of cooperation on structured populations where the distribution of public goods is driven by the reproductive success of individuals. Phase diagrams reveal that cooperation is promoted irrespective of the uncertainty by strategy adoptions and the type of interaction graph, yet the complete dominance of cooperators is elusive due to the spontaneous emergence of superpersistent defectors that owe their survival to extremely rare microscopic patterns. This indicates that success-driven mechanisms are crucial for effectively harvesting benefits from collective actions but that they may also account for the observed persistence of maladaptive behavior.

  17. Promotion of cooperation induced by nonuniform payoff allocation in spatial public goods game

    A nonuniform payoff allocation mechanism is proposed for spatial public goods games where individuals are nodes on a scale-free network. Each individual is assigned a weight ki α, where ki is the degree of individual i and α is an adjustable parameter that controls the degree of diversity in individuals’ profits. During the evolution progress, the allocation of payoff on individual i is assumed to be proportional to its weight. Individuals synchronously update their strategies according to the stochastic rule with a fixed noise level. It is found that there exists an optimal value of α which yields the highest level of cooperation. Other pertinent quantities, including the payoff and the probability of finding a node playing as cooperator versus the degree, are also investigated computationally and analytically. Our results suggest that a suitable degree of diversity among individuals can promote the emergence of cooperation.

  2. Akt3 and Mutant V600EB-Raf Cooperate to Promote Early Melanoma Development

    PubMed Central

    Cheung, Mitchell; Sharma, Arati; Madhunapantula, SubbaRao V.; Robertson, Gavin P.

    2008-01-01

    B-Raf is the most mutated gene in melanoma; however, mechanism through which it promotes early melanomas remains uncertain. Most nevi contain activated V600EB-Raf but few develop into melanoma and expression in melanocytes is inhibitory with low protein levels present in surviving cells, suggesting unknown cooperative oncogenic events are necessary for melanoma development. Since many melanomas have V600EB-Raf and active Akt3, it is possible these proteins cooperatively facilitate melanocyte transformation. In this study, Akt3 is shown to phosphorylate V600EB-Raf to lower its activity as well as that of the downstream MAP kinase pathway to levels promoting early melanoma development. Expression of active Akt3 in early melanoma cells containing V600EB-Raf reduced MAP kinase signaling and promoted anchorage independent growth. Furthermore, expression of both V600EB-Raf and active Akt3 in melanocytes promoted a transformed phenotype. Mechanistically, aberrant Akt3 activity in early melanomas serves to phosphorylate serines 364 and 428 on V600EB-Raf in order to reduce activity of V600EB-Raf to levels that promote rather than inhibit proliferation, which aids melanocytic transformation. Inhibition of V600EB-Raf or Akt3 in advanced melanoma cells in which both pathways were active reduced anchorage independent growth and tumor development in a cooperatively acting manner. Inhibition of Akt3 alone in these cells led to increased MAP kinase signaling. In summary, these results suggest that activating B-Raf mutations initially promote nevi development but the resulting high, intense activation of the MAP kinase pathway inhibits further tumor progression requiring Akt3 activation to bypass this barrier and aid melanoma development.

    Investigation of anti-social punishment has shaken the positive role of punishment in the evolution of cooperation. However, punishment is ubiquitous in nature, and the centralized, apposed to decentralized, punishment is more favored by certain modern societies in particular. To explore the underlying principle of such phenomenon, we study the evolution of cooperation in the context of pro- and anti-social punishments subject to two distinct patterns: costly centralized and decentralized punishments. The results suggest that the pattern of punishment has a great effect on the role of punishment in the evolution of cooperation. In the absence of anti-social punishment, the costly centralized punishment is more effective in promoting the emergence of cooperation. Anti-social punishment can subvert the positive role of punishment when anti- and pro-social punishments are in the same pattern. However, driven by centralized pro-social punishment, cooperation can be more advantageous than defection even in the presence of decentralized anti-social punishment. PMID:26408337

    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.

  6. Social diversity and promotion of cooperation in the spatial prisoner's dilemma game

    2008-01-01

    The diversity in wealth and social status is present not only among humans, but throughout the animal world. We account for this observation by generating random variables that determine the social diversity of players engaging in the prisoner’s dilemma game. Here the term social diversity is used to address extrinsic factors that determine the mapping of game payoffs to individual fitness. These factors may increase or decrease the fitness of a player depending on its location on the spatial grid. We consider different distributions of extrinsic factors that determine the social diversity of players, and find that the power-law distribution enables the best promotion of cooperation. The facilitation of the cooperative strategy relies mostly on the inhomogeneous social state of players, resulting in the formation of cooperative clusters which are ruled by socially high-ranking players that are able to prevail against the defectors even when there is a large temptation to defect. To confirm this, we also study the impact of spatially correlated social diversity and find that cooperation deteriorates as the spatial correlation length increases. Our results suggest that the distribution of wealth and social status might have played a crucial role by the evolution of cooperation amongst egoistic individuals.

    In realistic world individuals with high reputation are more likely to influence the collective behaviors. Due to the cost and error of information dissemination, however, it is unreasonable to assign each individual with a complete cognitive power, which means that not everyone can accurately realize others' reputation situation. Here we introduce the mechanism of inferring reputation into the selection of potential strategy sources to explore the evolution of cooperation. Before the game each player is assigned with a randomly distributed parameter p denoting his ability to infer the reputation of others. The parameter p of each individual is kept constant during the game. The value of p indicates that the neighbor possessing highest reputation is chosen with the probability p and randomly choosing an opponent is left with the probability 1-p. We find that this novel mechanism can be seen as an universally applicable promoter of cooperation, which works on various interaction networks and in different types of evolutionary game. Of particular interest is the fact that, in the early stages of evolutionary process, cooperators with high reputation who are easily regarded as the potential strategy donors can quickly lead to the formation of extremely robust clusters of cooperators that are impervious to defector attacks. These clusters eventually help cooperators reach their undisputed dominance, which transcends what can be warranted by the spatial reciprocity alone. Moreover, we provide complete phase diagrams to depict the impact of uncertainty in strategy adoptions and conclude that the effective interaction topology structure may be altered under such a mechanism. When the estimation of reputation is extended, we also show that the moderate value of evaluation factor enables cooperation to thrive best. We thus present a viable method of understanding the ubiquitous cooperative behaviors in nature and hope that it will inspire further studies to resolve social

    Childs, J. R.; Wardell, N.; Cooper, A. K.; Brancolini, G.

    2001-12-01

    The Antarctic Seismic Data Library System for Cooperative Research (SDLS) was designed by members of the Antarctic geoscience community to facilitate open access to multichannel seismic reflection data, and to promote collaborative research based on these data. The SDLS was formally adopted in 1991 under the auspices of the Scientific Committee on Antarctic Research (SCAR) and mandates of Antarctic Treaty Consultative Meeting Recommendation XVI-12. Since that time, library branches have been established in countries worldwide, and more than 50,000 km of digital seismic reflection profile data have been provided to the SDLS by data collectors in 10 countries. The library system is a dynamic library where data resides for use by all members of the research community in collaboration with data collectors. Data are available at the SDLS during the period between 4 and 8 years following data collection, after which they go to the World Data Center. The SDLS system protects intellectual property rights of data collectors and provides open access to data, as required by the Antarctic Treaty, to facilitate timely and multinational geoscience research products. This abstract outlines recommendations to update the data-access technology used by the SDLS, while retaining the basic tenets and guidelines upon which the library system was adopted and now operates. In the early 1990's when the SDLS was developed, the computer technologies were by today's standards primitive. We propose an updated SDLS design that incorporates a variety of new features and capabilities utilizing modern technology and current standards for the organization and dissemination of geospatial data. Some of the features of the proposed SDLS design include: ” The new SDLS will be principally Web-based, allowing on-line access to digital datasets. Security and access to data will be controlled according to the terms of the original SDLS agreement, either by limiting on-line access to sensitive data files

    Areas of family planning promotion which need to be further researched are identified. The effectiveness of diverse information, education, and communication approaches needs to be evaluated, feasible ways to increase contraceptive continuation rates must be identified, the relative merits of providing fieldworkers with salaries or incentives should be assessed, different styles of interactions between providers and clients should be identified and evaluated and research directed toward improving training programs, field supervision, and supply logistics should be undertaken. A number of more detailed research suggestions with special reference to Taiwan and other Asian and Pacific countries are also provided. Little is known, for example, about provider and user interaction patterns in Asia, and the impact of these patterns on contraceptive acceptance and continuance. These patterns could be analyzed using diverse research techniques ranging from observation to experimental manipulation. Despite the fact that approximately 50% of all acceptors discontinue use within 2 years, researchers tend to focus on identifying acceptor characteristics while ignoring the discontinuation process. Researcher should 1) identify the best time for providing postacceptance followup services, 2) identify training strategies which provide fieldworkers with the highest level of confidence in specific contraceptive methods, 3) experiment with the use of newspaper columns and telephone advisory services to provide users with information about side effects, 4) assess the merits of involving both partners in the contraceptive counseling process, 5) develop and evaluate postacceptance educational materials, and 6) assess the impact of various supply systems on contraceptive continuance. Another neglected area of research is the public's attitude toward different contraceptive knowledge sources. For example, receptivity to family planning messages may vary depending on wether the message is

    Dölling, D

    2000-09-01

    Even after the strengthening by the law of 1997, the German criminal law regarding corruption is no obstacle for cooperation between medical research and industry. The injustice of corruption is an irregular exchange between performing one's duty and benefits. According to this, an enterprise may give funds to a scientist for research purposes if no counter performance exceeding the research is associated with this. However, it makes a difference if the scientist has to show his appreciation by influencing economic decisions of the clinic in favor of the enterprise. In case of such an injustice, it is, under the new law, no longer important if the benefit is destined for the scientist himself or for another person or organization. Thus, it is in the interest of both research and industry to avoid the suspicion of corruption in the first place. A prerequisite for this is the strict observance of the legal and administrative regulations concerning projects financed by third-party funds.

  1. Technology certification and technology acceptance: Promoting interstate cooperation and market development for innovative technologies

    SciTech Connect

    1995-03-01

    In the past two years, public and private efforts to promote development and deployment of innovative environmental technologies have shifted from the analysis of barriers to the implementation of a variety of initiatives aimed at surmounting those barriers. Particular attention has been directed at (1) streamlining fragmented technology acceptance processes within and among the states, and (2) alleviating disincentives, created by inadequate or unverified technology cost and performance data, for users and regulators to choose innovative technologies. Market fragmentation currently imposes significant cost burdens on technology developers and inhibits the investment of private capital in environmental technology companies. Among the responses to these problems are state and federal technology certification/validation programs, efforts to standardize cost/performance data reporting, and initiatives aimed at promoting interstate cooperation in technology testing and evaluation. This paper reviews the current status of these initiatives, identifies critical challenges to their success, and recommends strategies for addressing those challenges.

    Holding on to one's strategy is natural and common if the later warrants success and satisfaction. This goes against widespread simulation practices of evolutionary games, where players frequently consider changing their strategy even though their payoffs may be marginally different than those of the other players. Inspired by this observation, we introduce an aspiration-based win-stay-lose-learn strategy updating rule into the spatial prisoner's dilemma game. The rule is simple and intuitive, foreseeing strategy changes only by dissatisfied players, who then attempt to adopt the strategy of one of their nearest neighbors, while the strategies of satisfied players are not subject to change. We find that the proposed win-stay-lose-learn rule promotes the evolution of cooperation, and it does so very robustly and independently of the initial conditions. In fact, we show that even a minute initial fraction of cooperators may be sufficient to eventually secure a highly cooperative final state. In addition to extensive simulation results that support our conclusions, we also present results obtained by means of the pair approximation of the studied game. Our findings continue the success story of related win-stay strategy updating rules, and by doing so reveal new ways of resolving the prisoner's dilemma. PMID:22363470

    Ets1 is a member of the Ets family of transcription factors. Ets1 is autoinhibited and its activation requires heterodimerization with a partner protein or DNA-mediated homodimerization for cooperative DNA binding. In the latter case, Ets1 molecules bind to palindromic sequences in which two Ets-binding sites (EBS) are separated by four base pairs, for example in the promoters of stromelysin-1 and p53. Interestingly, counteraction of autoinhibition requires the autoinhibitory region encoded by exon VII of the gene. The structural basis for the requirement of autoinhibitory sequences for Ets1 binding to palindromic EBS still remains unresolved. Here we report the crystal structure of two Ets1 molecules bound to an EBS palindrome of the stromelysin-1 promoter DNA, providing a plausible explanation for the requirement of exon VII-encoded sequences for Ets1 cooperative DNA binding. The proposed mechanism was verified both in vitro by surface plasmon resonance and in vivo by transcription-based assays.

The resultant private and nonprofit Japan Family Planning Association (JFPA) followed and it served to help Japan achieve its goal of reducing fertility by promoting family planning. It did so by publishing a monthly newsletter on family planning, hosting meetings and national conventions, spreading information via the mass media, and selling contraceptives and educational materials. JFPA earned funding from these sales with no support from the government thereby establishing self dependence and freedom to speak candidly to the government. The JFPA learned that families wanted to improve their standard of living and were willing to limit family size to 2 children. After the birth rate peaked in 1955, the birth rate and the number of illegal abortions decreased. In the 1950s, JFPA joined the International Planned Parenthood Federation and subsequently learned of the problems faced by developing countries. Based on the successful reduction of fertility in Japan and a strong economic base, JFPA and the government were in a position to organize an international cooperation program for family planning. Therefore, the leader of JFPA resigned to found the Japanese Organization for International Cooperation in Family Planning which promotes family planning in developing countries via its integrated family planning, nutrition, and parasite control program. A steering committee composed of leaders from government, universities, and private organizations sets the policies for the program in each country. It is to the Japanese government's advantage to work with private organizations instead of providing all social services because they are flexible and provide administrative stability and national expenses are minimized.

    Forming new, innovative collaborative approaches and cooperative learning methods between universities and hospitals maximize learning for undergraduate nursing students in a research course and provide professional development for nurses on the unit. The purpose of this Collaborative Approach and Learning Cooperatives (CALC) Model is to foster working relations between faculty and hospital administrators, maximize small group learning of undergraduate nursing students, and promote onsite knowledge of evidence based care for unit nurses. A quality improvement study using the CALC Model was implemented in an undergraduate nursing research course at a southern university. Hospital administrators provided a list of clinical concerns based on national performance outcome measures. Undergraduate junior nursing student teams chose a clinical question, gathered evidence from the literature, synthesized results, demonstrated practice application, and developed practice recommendations. The student teams developed posters, which were evaluated by hospital administrators. The administrators selected several posters to display on hospital units for continuing education opportunity. This CALC Model is a systematic, calculated approach and an economically feasible plan to maximize personnel and financial resources to optimize collaboration and cooperative learning. Universities and hospital administrators, nurses, and students benefit from working together and learning from each other. PMID:27067903

    In the current worldwide technology environment, it is essential for the U.S. microelectronics industry. and especially for the integrated circuit portion of that industry, that precompeutive cooperative research alliances be formed and funded at a level that emables them to be effective in rapidly advancing technology. It is important to realize that technology advances with or without our direct participation. If we do not aggressively participate we are quickly left behind. Increasing complexity and miniaturization have been the themes in semiconductor technology. Many are aware that what began in the early 60's with a few masking steps and minimum dimensions measured in mils. has now evolved to a level of sophistication requiring a 100 MW workstation for IC design and the investment of nearly S400 million dollars in fab cost to produce today's microchips. The leading nations of the world have come to realize that their future well-being is closely tied to their ability to compete in this hi-tech environment. Industry coalitions have been formed to exploit the early ramifications of emeging technologies. Improvements in overseas manufacturing have been made and continue unabated with new producLs, new processes, and new services being introduced at an increasing rate. Many foreign governments are now actively involved in formulating and conducting industrial and technology policies to aid their hi-tech industry. To meet these challenges, U.S. firms, with U. S. government cooperation, must respond.

  16. Autonomous Mobile Platform for Research in Cooperative Robotics

    NASA Technical Reports Server (NTRS)

    Daemi, Ali; Pena, Edward; Ferguson, Paul

    1998-01-01

    This paper describes the design and development of a platform for research in cooperative mobile robotics. The structure and mechanics of the vehicles are based on R/C cars. The vehicle is rendered mobile by a DC motor and servo motor. The perception of the robot's environment is achieved using IR sensors and a central vision system. A laptop computer processes images from a CCD camera located above the testing area to determine the position of objects in sight. This information is sent to each robot via RF modem. Each robot is operated by a Motorola 68HC11E micro-controller, and all actions of the robots are realized through the connections of IR sensors, modem, and motors. The intelligent behavior of each robot is based on a hierarchical fuzzy-rule based approach.

  17. Optimism when winning and cautiousness when losing promote cooperation in the spatial prisoner’s dilemma game

    In real societies, whether an individual participates in unpromising interactions sometimes is a probabilistic option instead of an all-or-nothing option, changing according to the risk of interactions. Inspired by this, we introduce an imitation-induced adjustment mechanism of individual willingness to interact into the spatial prisoner’s dilemma game, where an individual decreases its willingness to interact when it imitates others and increases when it is imitated by others. The adjustment value at each time interval is defined as the adjustment sensitivity of individual willingness to interact. Extensive simulation results show that the proposed mechanism can promote cooperation effectively, and a higher adjustment sensitivity has a more positive influence on the maintenance of cooperation. This promotion is mainly because the survived cooperators can resist the invasion of defectors, through interacting with defectors with lower willingness to interact around them. Finally, the generality of this promotion is testified in two additional scenarios.

    Peer-punishment is effective in promoting cooperation, but the costs associated with punishing defectors often exceed the benefits for the group. It has been argued that centralized punishment institutions can overcome the detrimental effects of peer-punishment. However, this argument presupposes the existence of a legitimate authority and leaves an unresolved gap in the transition from peer-punishment to centralized punishment. Here we show that the origins of centralized punishment could lie in individuals' distinct ability to punish defectors. In our laboratory experiment, we vary the structure of the punishment situation to disentangle the effects of punitive preferences, monetary incentives, and individual punishment costs on the punishment of defectors. We find that actors tacitly coordinate on the strongest group member to punish defectors, even if the strongest individual incurs a net loss from punishment. Such coordination leads to a more effective and more efficient provision of a cooperative environment than we observe in groups of all equals. Our results show that even an arbitrary assignment of an individual to a focal position in the social hierarchy can trigger the endogenous emergence of more centralized forms of punishment.

  10. Rho family GTPases cooperate with p53 deletion to promote primary mouse embryonic fibroblast cell invasion.

    PubMed

    Guo, Fukun; Zheng, Yi

    2004-07-22

    The Rho family GTPases Rac1, RhoA and Cdc42 function as molecular switches that transduce intracellular signals regulating multiple cell functions including gene expression, adhesion, migration and invasion. p53 and its regulator p19Arf, on the other hand, are tumor suppressors that are critical in regulating cell cycle progression and apoptosis. Previously, we have demonstrated that the Rho proteins contribute to the cell proliferation, gene transcription and migration phenotypes unleashed by p19Arf or p53 deletion in primary mouse embryo fibroblasts (MEFs). To further investigate their functional interaction in the present study, we have examined the involvement of Rho signaling pathways in p53-mediated cell invasion. We found that in primary MEFs (1) p53 or p19Arf deficiency led to a marked increase in the number of focal adhesion plaques and fibronectin production, and RhoA, Rac1 and Cdc42 contribute to the p53- and p19Arf-mediated focal adhesion regulation, but not fibronectin synthesis; (2) although endogenous Rac1 activity was required for the p19Arf or p53 deficiency-induced migration phenotype, hyperactive Rho GTPases could not further enhance cell migration, rather they suppressed cell-cell adhesion of p53-/- MEFs; (3) expression of the active mutant of RhoA, Rac1 or Cdc42, but not Ras, promoted an invasion phenotype of p53-/-, not p19Arf-/-, cells; (4) although ROCK activation can partially recapitulate Rho-induced invasion phenotype, multiple pathways regulated by RhoA, in addition to ROCK, are required to fully cooperate with p53 deficiency to promote cell invasion; and (5) extracellular proteases produced by the active RhoA-transduced cells are also required for the invasion phenotype of p53-/- cells. Combined with our previous observations, these results strongly suggest that mitogenic activation of Rho family GTPases can cooperate with p53 deficiency to promote primary cell invasion as well as transformation and that multiple signaling components

    1991-01-01

    The Office of Technology Development (OTD) of the National Cancer Institute (NCI) is responsible for negotiating Cooperative Research and Development Agreements (CRADAs), whereby the knowledge resulting from NCI investigators' government-sponsored research is developed in collaboration with universities and/or industry into new products of importance for the diagnosis and treatment of cancer and acquired immunodeficiency syndrome (AIDS). The NCI has recently executed a unique 'clinical trials' CRADA and is developing a model agreement based upon it for the development and commercialization of products for the diagnosis and treatment of cancer and AIDS. NCI drug screening, preclinical testing, clinical trials, and AIDS program capabilities form the basis for this new technology development/technology transfer vehicle. NCI's extensive drug screening program and 'designer foods' program serve as potential sources of investigational new drugs (INDs) and cancer preventatives. Collaborations between NCI and pharmaceutical companies having the facilities, experience, and expertise necessary to develop INDs into approved drugs available to the public are being encouraged where the companies have proprietary rights to INDs, or where NCI has proprietary rights to INDs and invites companies to respond to a collaborator announcement published in the Federal Register. The joint efforts of the NCI and the chosen collaborator are designed to generate the data necessary to obtain pharmaceutic regulatory approval from the Food and Drug Administration (FDA) to market the drugs developed, and thereby make them available to health care providers for the diagnosis and treatment of cancer and AIDS.

    It is a reasonable and workable strategy, that multi-UAV can complement each other and cooperate closely, play fully the comprehensive combat effectiveness of the UAV formation. The paper introduced multi-agent technology and information fusion technology into the UAV formation system, constructed formation cooperative detection task planning system and formation cooperative detection information fusion system, and analyzed their structure and operating mechanism. In addition, combining responses of the UAV formation when facing unexpected threats, the paper explored the cooperative detection strategy of the UAV formation. The research results also show some useful reference for cooperative operations of the other multi-platform system.

    On June 1, 1980, the University of Akron and the NASA Lewis Research Center (LERC) established a Graduate Cooperative Fellowship Program in the specialized areas of Engine Structural Analysis and Dynamics, Computational Mechanics, Mechanics of Composite Materials, and Structural Optimization, in order to promote and develop requisite technologies in these areas of engine technology. The objectives of this program are consistent with those of the NASA Engine Structure Program in which graduate students of the University of Akron participate by conducting research at Lewis. This report is the second on this grant and summarizes the second and third year research effort, which includes the participation of five graduate students where each student selects one of the above areas as his special field of interest. Each student is required to spend 30 percent of his educational training time at the NASA Lewis Research Center and the balance at the University of Akron. His course work is judiciously selected and tailored to prepare him for research work in his field of interest. A research topic is selected for each student while in residence at the NASA Lewis Research Center, which is also approved by the faculty of the University of Akron as his thesis topic for a Master's and/or a Ph.D. degree.

    The U.S. Department of Energy, National Nuclear Security Administration (DOE/NNSA) has initiated collaborations with the national nuclear authorities of Egypt, Peru, and Romania for the purpose of advancing the commercial potential and utilization of their respective research reactors. Under its Office of International Safeguards ''Sister Laboratory'' program, DOE/NNSA has undertaken numerous technical collaborations over the past decade intended to promote peaceful applications of nuclear technology. Among these has been technical assistance in research reactor applications, such as neutron activation analysis, nuclear analysis, reactor physics, and medical radioisotope production. The current collaborations are intended to provide the subject countries with a methodology for greater commercialization of research reactor products and services. Our primary goal is the transfer of knowledge, both in administrative and technical issues, needed for the establishment of an effective business plan and utilization strategy for the continued operation of the countries' research reactors. Technical consultation, cooperation, and the information transfer provided are related to: identification, evaluation, and assessment of current research reactor capabilities for products and services; identification of opportunities for technical upgrades for new or expanded products and services; advice and consultation on research reactor upgrades and technical modifications; characterization of markets for reactor products and services; identification of competition and estimation of potential for market penetration; integration of technical constraints; estimation of cash flow streams; and case studies.

    Steroid hormone biosynthesis requires the steroidogenic acute regulatory protein (STAR). STAR is part of a protein complex that transports cholesterol through the mitochondrial membrane where steroidogenesis begins. Several transcription factors participate to direct the proper spatiotemporal and hormonal regulation of the Star gene in Leydig cells. Mechanistically, this is believed to involve the functional interplay between many of these factors. Here we report a novel transcriptional cooperation between GATA factors and cJUN on the mouse Star and human STAR promoters in MA-10 Leydig cells. This cooperation was observed with different GATA members (GATA1, 4, and 6), whereas only cJUN could cooperate with GATA factors. GATA/cJUN transcriptional cooperation on the Star promoter is mediated via closely juxtaposed GATA and AP-1 binding motifs. Mutation of all functional GATA and cJUN elements abolished GATA/cJUN cooperation, which is in agreement with previous data reporting a direct interaction between GATA4 and cJUN in a heterologous system. These data add valuable new insights that further define the molecular mechanisms that govern Star transcription in steroidogenic cells of the testis.

    The participants in the Eriksholm Workshop on "Measuring Outcomes in Audiological Rehabilitation Using Hearing Aids" debated three issues that are reported in this article. First, it was agreed that the characteristics of an optimal outcome measure vary as a function of the purpose of the measurement. Potential characteristics of outcome self-report tools for four common goals of outcome measurement are briefly presented to illustrate this point. Second, 10 important research priorities in outcome measurement were identified and ranked. They are presented with brief discussion of the top five. Third, the concept of generating a brief universally applicable outcome measure was endorsed. This brief data set is intended to supplement existing outcome measures and to promote data combination and comparison across different social, cultural, and health-care delivery systems. A set of seven core items is proposed for further study.

    The ubiquity of cooperation in nature is puzzling because cooperators can be exploited by defectors. Recent theoretical work shows that if dynamic networks define interactions between individuals, cooperation is favoured by natural selection. To address this, we compare cooperative behaviour in multiple but independent repeated games between participants in static and dynamic networks. In the latter, participants could break their links after each social interaction. As predicted, we find higher levels of cooperation in dynamic networks. Through biased link breaking (i.e. to defectors) participants affected their social environment. We show that this link-breaking behaviour leads to substantial network clustering and we find primarily cooperators within these clusters. This assortment is remarkable because it occurred on top of behavioural assortment through direct reciprocity and beyond the perception of participants, and represents a self-organized pattern. Our results highlight the importance of the interaction between ecological context and selective pressures on cooperation. PMID:21463459

    The association of DSIF and NELF with initiated RNA Polymerase II (Pol II) is the general mechanism for inducing promoter-proximal pausing of Pol II. However, it remains largely unclear how the paused Pol II is released in response to stimulation. Here, we show that the release of the paused Pol II is cooperatively regulated by multiple P-TEFbs which are recruited by bromodomain-containing protein Brd4 and super elongation complex (SEC) via different recruitment mechanisms. Upon stimulation, Brd4 recruits P-TEFb to Spt5/DSIF via a recruitment pathway consisting of Med1, Med23 and Tat-SF1, whereas SEC recruits P-TEFb to NELF-A and NELF-E via Paf1c and Med26, respectively. P-TEFb-mediated phosphorylation of Spt5, NELF-A and NELF-E results in the dissociation of NELF from Pol II, thereby transiting transcription from pausing to elongation. Additionally, we demonstrate that P-TEFb-mediated Ser2 phosphorylation of Pol II is dispensable for pause release. Therefore, our studies reveal a co-regulatory mechanism of Brd4 and SEC in modulating the transcriptional pause release by recruiting multiple P-TEFbs via a Mediator- and Paf1c-coordinated recruitment network.

  11. Cooperativity and interaction energy threshold effects in recognition of the -10 promoter element by bacterial RNA polymerase.

    PubMed

    Mekler, Vladimir; Severinov, Konstantin

    2013-08-01

    RNA polymerase (RNAP) melts promoter DNA to form transcription-competent open promoter complex (RPo). Interaction of the RNAP σ subunit with non-template strand bases of a conserved -10 element (consensus sequence T-12A-11T-10A-9A-8T-7) is an important source of energy-driving localized promoter melting. Here, we used an RNAP molecular beacon assay to investigate interdependencies of RNAP interactions with -10 element nucleotides. The results reveal a strong cooperation between RNAP interactions with individual -10 element non-template strand nucleotides and indicate that recognition of the -10 element bases occurs only when free energy of the overall RNAP -10 element binding reaches a certain threshold level. The threshold-like mode of the -10 element recognition may be related to the energetic cost of attaining a conformation of the -10 element that is recognizable by RNAP. The RNAP interaction with T/A-12 base pair was found to be strongly stimulated by RNAP interactions with other -10 element bases and with promoter spacer between the -10 and -35 promoter elements. The data also indicate that unmelted -10 promoter element can impair RNAP interactions with promoter DNA upstream of the -11 position. We suggest that cooperativity and threshold effects are important factors guiding the dynamics and selectivity of RPo formation.

  19. COSPAR, a platform for international cooperation in space research

    NASA Astrophysics Data System (ADS)

    Fellous, Jean-Louis

    The Committee on Space Research (COSPAR) was founded by the International Council for Science (ICSU) in 1958, with the aim of favouring the dialogue between the USSR and USA in the time of the Cold War. Fifty-six years later, COSPAR is continuing its mission of service to the worldwide space research community. Thousands of scientists attend COSPAR assemblies, read and publish their results in its journals, participate in its workshops, colloquia and symposia, but many are unaware of the wealth of activities that COSPAR undertakes or supports. Many of them ignore the processes through which this organisation develops its activities, how it is structured, how to get involved in its governance, how to promote new initiatives with its help, etc. Young space scientists do not know the history of, and prominent roles played by COSPAR, past and present, and more importantly need to understand better the benefits that can be accrued from their involvement within COSPAR. This presentation will review these aspects and offer all interested scientists a detailed overview of COSPAR activities and plans for the future.

    Viral hepatitis is currently a major global cause of morbidity and mortality. In some Asian countries like China and Japan, Hepatitis B and C in particular are the most common extremely infectious diseases and are likely to develop into liver cirrhosis. Furthermore, statistics indicate that patients with liver cirrhosis resulting from hepatitis B and C have an increased risk of developing hepatocellular carcinoma (HCC). Scientists have worked tirelessly to find curative therapeutic strategies to control chronic hepatitis and liver cirrhosis, accompanied by improvements in public health and living conditions. China's Shandong University and the University of Tokyo in Japan previously established a longterm cooperative relationship. Cooperative programs include co-training of postgraduates, exchanges of visiting scholars, academic symposia, and a bilateral international joint research program. Some substantive progress has been made as a result of bilateral endeavors. For instance, the Shandong University China-Japan Cooperation Center for Drug Discovery & Screening (SDU-DDSC) has enhanced to serve as an important platform for further close cooperation. At the same time, the International Advancement Center for Medicine & Health Research (IACMHR) - "Drug Discoveries and Therapeutics" and International Research and Cooperation Association for Bio & Socio-Sciences Advancement (IRCA-BSSA) - "BioScience Trends" were established (Visit http://www.ddtjournal.com and http://www.biosciencetrends.com ). The first China-Japan conference on new drug discoveries and therapeutics (CJMWDDT 2007) was recently held in Jinan, China May 27-29, 2007, which provided opportunities for further communication and cooperation and increased knowledge of new drug research and clinical cures for hepatitis.

    As more journals and funding organizations require data to be made available, more and more scientists are being exposed to the world of data science, metadata development, and data standards so they can ensure future funding and publishing success. The Gulf of Mexico Research Initiative Information and Data Cooperative (GRIIDC) is the vehicle by which the Gulf of Mexico Research Initiative (GOMRI) is making all data collected in this program publically available. This varied group of researchers all have different levels of experience with data management standards and protocols, thus GRIIDC has evolved to embrace the cooperative nature of our work and develop a number of tools and training materials to help ensure data managers and researchers in the GoMRI program are submitting high quality data and metadata that will be useful for years to come. GRIIDC began with a group of 8 data managers many of which had only ever managed their own data, who were then expected to manage the data of a large group of geographically distant researchers. As the program continued to evolve these data managers worked with the GRIIDC team to help identify and develop much needed resources for training and communication for themselves and the scientists they represented. This essential cooperation has developed a team of highly motivated scientists, computer programmers and data scientists who are working to ensure a data and information legacy that promotes continual scientific discovery and public awareness of the Gulf of Mexico Ecosystem and beyond.

    Those in charge of directing scientific research face a daunting task: finding a proper balance between excellence in research and that research's relevance to people's health problems. In developing countries, this task is further hampered by deficient scientific and technological infrastructure, the lack of competitiveness of its research community, and the shortage of research funds. This article explains some of the mechanisms that have been put in place in Latin America to achieve a balance between excellence and relevance, especially by promoting research that targets pertinent public health problems. Within this context, the multicenter studies being conducted under the auspices of the Pan American Health Organization's Program for the Support of Research are described. The article also lays out the fundamental features of a new model for international cooperation to generate knowledge to help resolve the public health problems of the countries of the Americas.

    Industry sponsors medical research in the fields of pharmaceutical products, diagnostics, medical technology, medical equipment, clinical nutrition and information systems. In pharmaceutical research, the companies of VFA invested a total of DM 4.3 billion in 1995, that means 18% of the turnover. DM 1.4 billion were spent mainly on clinical research studies. Beyond this, industry shares the costs of academic research institutes and gives support through its foundations. The decreasing number of domestic clinical studies, that German clinics complain about, is caused by organisational and administrative deficiencies, leading to major economic disadvantages. Recommendations of how to improve the situation exist and must be implemented.

    The ultimate objective of this research has been to uncover novel reagents and experimental conditions for heteroatom removal and hydrogen transfer processes, which would be applicable to the liquefaction of coal under low-severity conditions. To this end, one phase of this research has investigated the cleavage of carbon-heteroatom bonds involving sulfur, oxygen, nitrogen and halogen by subvalent transition-metal complexes. A second phase of the study has assessed the capability of the same transition-metal complexes or of organoaluminum Lewis acids to catalyze the cleavage of carbon-hydrogen bonds in aromatics and hence to promote hydrogen shuttling. Finally, a third phase of our work has uncovered a remarkable synergistic effect of combinations of transition metals with organoaluminum Lewis acids on hydrogen shuttling between aromatics and hydroaromatics.

    We study the evolution of cooperation in spatial prisoner's dilemma by proposing an aspiration-based preference learning, under which individuals switch the learning agents only if the achieved payoffs are lower than their aspirations. Both synchronous and asynchronous updates are considered. We find that the aspiration level can substantially influence the evolution of cooperation, with the moderate aspiration level leading to a plateau of the high cooperation level. There exist phase transitions for proper combinations of parameters and we give an analysis for the phase transition points. We also investigate the stationary configuration patterns and the stationary distributions of cooperators and defectors on the square lattice for a comprehensive understanding. The behavior of the well-mixed system of our model has also been discussed. Our results may provide further insights into understanding the role played by individual aspiration in the emergence of cooperation.

The article also outlines the measures proposed by the authors to promote world-wide co-operation in controlling the illicit traffic in drugs. The authors make the following suggestions: in order to prevent individuals involved in organized crime from profiting from their illegal activities, standards for criminal laws should be established at the international level to ensure that no country or territory can be used as a haven for organized crime and profits derived from it; national Governments must ensure that co-operation is extended to all investigations and enquiries concerning organized crime; bilateral and multilateral treaties should be developed and adopted to ensure the exchange of information and mutual co-operation in law enforcement action against organized crime; international co-operation is needed to ensure the effective prosecution of individuals involved in organized international criminal groups and the removal of their illegally accumulated profits, which should result in the dismantling of the illegal organizations to prevent their entrenchment in contemporary societies.

  16. A structured population model suggests that long life and post-reproductive lifespan promote the evolution of cooperation.

    2015-03-21

    Social organization correlates with longevity across animal taxa. This correlation has been explained by selection for longevity by social evolution. The reverse causality is also conceivable but has not been sufficiently considered. We constructed a simple, spatially structured population model of asexually reproducing individuals to study the effect of temporal life history structuring on the evolution of cooperation. Individuals employed fixed strategies of cooperation or defection towards all neighbours in a basic Prisoner's Dilemma paradigm. Individuals aged and transitioned through different life history stages asynchronously without migration. An individual's death triggered a reproductive event by one immediate neighbour. The specific neighbour was chosen probabilistically according to the cumulative payoff from all local interactions. Varying the duration of pre-reproductive, reproductive, and post-reproductive life history stages, long-term simulations allowed a systematic evaluation of the influence of the duration of these specific life history stages. Our results revealed complex interactions among the effects of the three basic life history stages and the benefit to defect. Overall, a long post-reproductive stage promoted the evolution of cooperation, while a prolonged pre-reproductive stage has a negative effect. In general, the total length of life also increased the probability of the evolution of cooperation. Thus, our specific model suggests that the timing of life history transitions and total duration of life history stages may affect the evolution of cooperative behaviour. We conclude that the causation of the empirically observed association of life expectancy and sociality may be more complex than previously realized.

  1. The cooperative research unit program and wildlife education: Historic development, future challenges

    2000-01-01

    In 1932, J. N. 'Ding' Darling proposed a 3-year tripartite arrangement between the Iowa Fish and Game Commission, Iowa State University, and himself to establish the first Cooperative Wildlife Research Unit. Three years later, the Cooperative Wildlife Research Unit Program was broadened to include 9 land-grant colleges representing recognized ecoregions in the United States. In 1960, the Units were given statutory recognition by Public Law 86-686 that also included provision for establishing Cooperative Fishery Units. The Cooperative Research Unit idea has evolved to 39 Units in 2000. Today, the main cooperators of the Unit program are the land-grant university, the state fish and game or conservation agency, the U.S. Geological Survey, and the Wildlife Management Institute. The Cooperative Units mission, as stated in Public Law 86-686, remains: 'To facilitate cooperation between the Federal Government, colleges and universities, and private organizations for cooperative unit programs of research and education relating to fish and wildlife and for other purposes.' Graduate research and education continue to be the program's primary missions. In any given year >600 graduate and post-graduate students are involved. Post-graduate employment of Unit-afffiliated students is >90%. Perhaps the primary benefit to the education process is the Units' formal connection to the state cooperator and to their federal agency that might not otherwise be available to university faculty and students. Units are conduits to state and federal funding for research projects conducted by university faculty and students. The CRU program is well positioned to educate a multitalented, ethnically diverse cadre of graduate students who will be prepared not only for their first professional job but also for their career by having been instilled with a desire for life-long professional accomplishment.

    Cooperative research and development activities at the NASA Langley Research Center (LaRC) involving reduced-order modeling (ROM) techniques are presented. Emphasis is given to reduced-order methods and analyses based on Volterra series representations, although some recent results using Proper Orthogonal Deco in position (POD) are discussed as well. Results are reported for a variety of computational and experimental nonlinear systems to provide clear examples of the use of reduced-order models, particularly within the field of computational aeroelasticity. The need for and the relative performance (speed, accuracy, and robustness) of reduced-order modeling strategies is documented. The development of unsteady aerodynamic state-space models directly from computational fluid dynamics analyses is presented in addition to analytical and experimental identifications of Volterra kernels. Finally, future directions for this research activity are summarized.

  7. Datathons and Software to Promote Reproducible Research

    PubMed Central

    2016-01-01

    Background Datathons facilitate collaboration between clinicians, statisticians, and data scientists in order to answer important clinical questions. Previous datathons have resulted in numerous publications of interest to the critical care community and serve as a viable model for interdisciplinary collaboration. Objective We report on an open-source software called Chatto that was created by members of our group, in the context of the second international Critical Care Datathon, held in September 2015. Methods Datathon participants formed teams to discuss potential research questions and the methods required to address them. They were provided with the Chatto suite of tools to facilitate their teamwork. Each multidisciplinary team spent the next 2 days with clinicians working alongside data scientists to write code, extract and analyze data, and reformulate their queries in real time as needed. All projects were then presented on the last day of the datathon to a panel of judges that consisted of clinicians and scientists. Results Use of Chatto was particularly effective in the datathon setting, enabling teams to reduce the time spent configuring their research environments to just a few minutes—a process that would normally take hours to days. Chatto continued to serve as a useful research tool after the conclusion of the datathon. Conclusions This suite of tools fulfills two purposes: (1) facilitation of interdisciplinary teamwork through archiving and version control of datasets, analytical code, and team discussions, and (2) advancement of research reproducibility by functioning postpublication as an online environment in which independent investigators can rerun or modify analyses with relative ease. With the introduction of Chatto, we hope to solve a variety of challenges presented by collaborative data mining projects while improving research reproducibility. PMID:27558834

  8. Cooperation between distinct viral variants promotes growth of H3N2 influenza in cell culture.

    2016-01-01

    RNA viruses rapidly diversify into quasispecies of related genotypes. This genetic diversity has long been known to facilitate adaptation, but recent studies have suggested that cooperation between variants might also increase population fitness. Here, we demonstrate strong cooperation between two H3N2 influenza variants that differ by a single mutation at residue 151 in neuraminidase, which normally mediates viral exit from host cells. Residue 151 is often annotated as an ambiguous amino acid in sequenced isolates, indicating mixed viral populations. We show that mixed populations grow better than either variant alone in cell culture. Pure populations of either variant generate the other through mutation and then stably maintain a mix of the two genotypes. We suggest that cooperation arises because mixed populations combine one variant's proficiency at cell entry with the other's proficiency at cell exit. Our work demonstrates a specific cooperative interaction between defined variants in a viral quasispecies. PMID:26978794

  9. Power-law distributed temporal heterogeneity of human activities promotes cooperation on complex networks

    2016-09-01

    An evolutionary prisoner's dilemma game (PDG) with players located on Barabási-Albert scale-free networks is studied. The impact of players' heterogeneous temporal activity pattern on the evolution of cooperation is investigated. To this end, the normal procedure that players update their strategies immediately after a round of game is discarded. Instead, players update strategies according to their assigned reproduction time, which follows a power-law distribution. We find that the temporal heterogeneity of players' activities facilitates the prosperity of cooperation, indicating the important role of hubs in the maintenance of cooperation on scale-free networks. When the reproduction time is assigned to individuals negatively related to their degrees, a fluctuation of the cooperation level with the increase of the exponent β is observed.

  12. Discriminative host sanction together with relatedness promote the cooperation in fig/fig wasp mutualism.

    PubMed

    Wang, Rui-Wu; Sun, Bao-Fa; Yang, Yan

    2015-07-01

    Sanctioning or punishing is regarded as one of the most important dynamics in the evolution of cooperation. However, it has not been empirically examined yet whether or not such enforcement selection by sanctioning or punishing and classical theories like kin or reciprocity selection are separate mechanisms contributing to the evolution of cooperation. In addition, it remains largely unclear what factors determine the intensity or effectiveness of sanction. Here, we show that in the obligate, interspecific cooperation between figs and fig wasps, the hosted figs can discriminatively sanction cheating individuals by decreasing the offspring development ratio. Concurrently, the figs can reward the cooperative pollinators with a higher offspring development ratio. This sanction intensity and effectiveness largely depend on how closely the host and symbiont are related either in terms of reciprocity exchange or genetic similarity as measured by the reciprocal of the foundress number. Our results imply that in asymmetric systems, symbionts might be forced to evolve to be cooperative or even altruistic through discriminative sanction against the noncooperative symbiont and reward to the cooperative symbiont by the host (i.e. through a game of 'carrot and stick').

    PubMed

    St-Pierre, Angèle; Larose, Karine; Dubois, Frédérique

    2009-12-01

    Reciprocal altruism, one of the most probable explanations for cooperation among non-kin, has been modelled as a Prisoner's Dilemma. According to this game, cooperation could evolve when individuals, who expect to play again, use conditional strategies like tit-for-tat or Pavlov. There is evidence that humans use such strategies to achieve mutual cooperation, but most controlled experiments with non-human animals have failed to find cooperation. One reason for this could be that subjects fail to cooperate because they behave as if they were to play only once. To assess this hypothesis, we conducted an experiment with monogamous zebra finches (Taeniopygia guttata) that were tested in a two-choice apparatus, with either their social partner or an experimental opponent of the opposite sex. We found that zebra finches maintained high levels of cooperation in an iterated Prisoner's Dilemma game only when interacting with their social partner. Although other mechanisms may have contributed to the observed difference between the two treatments, our results support the hypothesis that animals do not systematically give in to the short-term temptation of cheating when long-term benefits exist. Thus, our findings contradict the commonly accepted idea that reciprocal altruism will be rare in non-human animals. PMID:19740884

  14. Hunting for wealthy encounters promotes cooperation in spatial Prisoner's Dilemma games

    NASA Astrophysics Data System (ADS)

    Yang, Zhihu; Wu, Te; Li, Zhi; Wang, Long

    2013-04-01

    We consider an evolutionary Prisoner's Dilemma game on the lattice where a parameter α is employed to determine with whom individuals aspire to interact in future iterations. Specifically, for positive α, rich environments are preferentially considered when individuals hunt for new surroundings, while for negative α, the opposite holds. When α = 0, individuals adopt `random move'-like migration. The results indicate that aspiring for wealthy ambience makes cooperation survive and even thrive under certain circumstances. Moreover, there exist the optimal population densities that most uphold cooperation. We also investigate the expansion of cooperators. And the discovery of utmost salience is that cooperators can spontaneously break out for the population consisting of full defectors in the presence of strategy mutation. Our results relax the requirements for cooperation to outbreak and suggest that spying into others' strategies is not always necessary for the cooperation to burst. Finally, we deepen our studies by exploring the situation that each individual has an independent α and find that the fate of evolution is mainly determined by the population composition in this scenario.

    The principal use of our Geowall system is to showcase the 3-D visualizations created by SCEC/EITR (Southern California Earthquake Center/Earthquake Information Technology Research) interns. These visualizations, called LA3D, are devised to educate the public, assist researchers, inspire students, and attract new interns. With the design criteria that LA3D code must be object-oriented and open-source, and that all datasets should be in internet-accessible databases, our interns have made interactive visualizations of southern California's earthquakes, faults, landforms, and other topographic features, that allow unlimited additions of new datasets and map objects. The interns built our Geowall system, and made a unique contribution to the Geowall consortium when they devised a simple way to use Java3D to create and send images to Geowall's projectors. The EIT interns are enormously proud of their accomplishments, and for most, working on LA3D has been the high point of their college careers. Their efforts have become central to testbed development of the system level science that SCEC is orchestrating in its Community Modeling Environment. In addition, SCEC's Communication, Education and Outreach Program uses LA3D on Geowall to communicate concepts about earthquakes and earthquake processes. Then, projecting LA3D on Geowall, it becomes easy to impress students from elementary to high school ages with what can be accomplished if they keep learning math and science. Finally, we bring Geowall to undergraduate research symposia and career-day open houses, to project LA3D and attract additional students to our intern program, which to date has united students in computer science, engineering, geoscience, mathematics, communication, pre-law, and cinema.

    2001-04-10

    ECVAM was established to play a leading role at the European level in the independent evaluation of the reliability and relevance of test methods and testing strategies for specific purposes through research on advanced methods and new test development and validation, so that chemicals and products of various kinds, including medicines, vaccines, medical devices, cosmetics, household products and agricultural products, can be manufactured, transported and used more economically and more safely, whilst the current relevance on animal test procedures is progressively reduced. Nowhere is this activity more necessary than in the field of immunotoxicology, where we know that chemicals and products of many kinds have the potential to stimulate, modulate or suppress the induction or expression of various types of immune responses. The problem is to effectively evaluate the potency of these effectors, and, since the available information is currently based on rather qualitative animal tests, to evaluate the true relevance of this knowledge and apply it intelligently in risk assessment processes which will protect human beings without unnecessarily limiting the development and use of materials which otherwise have economic, health and social benefits. The way forward must depend on the following: (a) a better understanding of immunotoxicological processes, based on a sounder understanding of the immune system itself (and of its network of control systems and interrelationships with other body systems); (b) The use of in vitro (not in vivo) systems based on human (not animal) cells and tissues; (c) integrated and tiered testing strategies, incorporating QSAR, as well as in vitro approaches; (d) taking advantage of the use of cells or factors from humans who have been exposed to potential immunotoxins, be this voluntarily, occupationally, environmentally or by accident; and (e) the recognition that virtually everything will effect one or more aspects of the immune system at

    1988-01-01

    Three laboratories participated in an interlaboratory study to evaluate the usefulness of the Chinese hamster V79 cell metabolic cooperation assay to predict the tumor-promoting activity of selected chemical. Twenty-three chemicals of different chemical structures (phorbol esters, barbiturates, phenols, artificial sweeteners, alkanes, and peroxides) were chosen for testing based on in vivo promotion activities, as reported in the literature. Assay protocols and materials were standardized, and the chemicals were coded to facilitate unbiased evaluation. A chemical was tested only once in each laboratory, with one of the three laboratories testing only 15 out of 23 chemicals. Dunnett's test was used for statistical analysis. Chemicals were scored as positive (at least two concentration levels statistically different than control), equivocal (only one concentration statistically different), or negative. For 15 chemicals tested in all three laboratories, there was complete agreement among the laboratories for nine chemicals. For the 23 chemicals tested in only two laboratories, there was agreement on 16 chemicals. With the exception of the peroxides and alkanes, the metabolic cooperation data were in general agreement with in vivo data. However, an overall evaluation of the V79 cell system for predicting in vivo promotion activity was difficult because of the organ specificity of certain chemicals and/or the limited number of adequately tested nonpromoting chemicals.

  9. Promotion of cooperation induced by a self-questioning update rule in the spatial traveler's dilemma game

    In sociology and economics, evolutionary game theory has provided a powerful framework to illustrate the social dilemma's problems, and many evolutionary game models are presented, such as prisoner's dilemma game, snowdrift game, public goods game, and so on. In this paper, however, we focus on another typical pair-wise game model: Traveler's Dilemma Game (TDG), which has been deeply investigated in economics, but less attention has been paid to this topic within the physics community. We mainly discuss the influence of strategy update rules on the evolution of cooperation in the spatial TDG, and in detail explore the role of a novel self-questioning or self-learning update mechanism in the evolution of cooperation of the TDG model on the square lattice. In our self-questioning rule, each player does not imitate the strategy state of his or her nearest neighbors and simply plays the traveler's dilemma games twice with nearest neighbors: one is to calculate the actual payoff in the current game round; the other is to perform a virtual game which is used to obtain an intangible payoff if he or she adopts another random strategy. Then, the focal player decides to keep the current strategy or to change into that virtual strategy according to the Fermi-like dynamics. A great number of Monte Carlo simulations indicate that our self-questioning rule is a low information game decision-making mechanism which can greatly promote the evolution of cooperation for some specific conditions in the spatial TDG model. Furthermore, this novel rule can also be applied into the prisoner's dilemma game, and likewise the behavior of cooperation can be largely enhanced. Our results are of high importance to analyze and understand the emergence of cooperation within many real social and economical systems.

    2012-10-01

    In this study, we propose a spatial prisoner's dilemma game model with a 2-stage strategy updating rule, and focus on the cooperation behavior of the system. In the first stage, i.e., the pre-learning stage, a focal player decides whether to update his strategy according to the pre-learning factor β and the payoff difference between himself and the average of his neighbors. If the player makes up his mind to update, he enters into the second stage, i.e., the learning stage, and adopts a strategy of a randomly selected neighbor according to the standard Fermi updating rule. The simulation results show that the cooperation level has a non-trivial dependence on the pre-learning factor. Generally, the cooperation frequency decreases as the pre-learning factor increases; but a high cooperation level can be obtained in the intermediate region of -3 < β < -1. We then give some explanations via studying the co-action of pre-learning and learning. Our results may sharpen the understanding of the influence of the strategy updating rule on evolutionary games.

    1997-01-01

    The Swedish International Development Cooperation Agency (SIDA) has created an Action Program for Promoting Equality Between Women and Men in Partner Countries that emphasizes competency development as a means of achieving gender equality. Competency development goes beyond formal training and utilizes existing entry points while creating innovative ones. SIDA's partnership approach requires clear delineation of roles for SIDA personnel and partner countries, with SIDA 1) applying a gender perspective to assessments, 2) initiating a constructive dialogue about gender equality if needed, 3) assessing the need for gender equality promoting competency development, 4) studying the local context, and 5) developing effective local networks. In addition, the needs of different groups within SIDA should be met with appropriate competency development inputs while SIDA continues support to competency development in partner countries by developing local capacity for gender training and gender sensitization at the regional and national levels. At SIDA, gender training has evolved since 1989 to its current focus on the practical and concrete challenges facing participants. In addition, departments and divisions conduct sector- and issue-specific training, and gender equality is integrated in all SIDA training activities on every topic. The challenges for future competency development are to 1) increase the number of men involved in provision of competency development inputs, 2) improve competency at embassy and field levels, and 3) improve competency in policy dialogues.

  13. Navigating the ethics of cross-cultural health promotion research.

    PubMed

    Haintz, Greer Lamaro; Graham, Melissa; McKenzie, Hayley

    2015-12-01

    Health promotion researchers must consider the ethics of their research, and are usually required to abide by a set of ethical requirements stipulated by governing bodies (such as the Australian National Health and Medical Research Council) and human research ethics committees (HRECs). These requirements address both deontological (rule-based) and consequence-based issues. However, at times there can be a disconnect between the requirements of deontological issues and the cultural sensitivity required when research is set in cultural contexts and settings etic to the HREC. This poses a challenge for health promotion researchers who must negotiate between meeting both the requirements of the HREC and the needs of the community with whom the research is being conducted. Drawing on two case studies, this paper discusses examples from cross-cultural health promotion research in Australian and international settings where disconnect arose and negotiation was required to appropriately meet the needs of all parties. The examples relate to issues of participant recruitment and informed consent, participants under the Australian legal age of consent, participant withdrawal when this seemingly occurs in an ad hoc rather than a formal manner and reciprocity. Although these approaches are context specific, they highlight issues for consideration to advance more culturally appropriate practice in research ethics and suggest ways a stronger anthropological lens can be applied to research ethics to overcome these challenges.

  16. Co-operative DNA binding by GAGA transcription factor requires the conserved BTB/POZ domain and reorganizes promoter topology.

    The POZ domain is a conserved protein-protein interaction motif present in a variety of transcription factors involved in development, chromatin remodelling and human cancers. Here, we study the role of the POZ domain of the GAGA transcription factor in promoter recognition. Natural target promoters for GAGA typically contain multiple GAGA-binding elements. Our results show that the POZ domain mediates strong co-operative binding to multiple sites but inhibits binding to single sites. Protein cross-linking and gel filtration chromatography experiments established that the POZ domain is required for GAGA oligomerization into higher order complexes. Thus, GAGA oligomerization increases binding specificity by selecting only promoters with multiple sites. Electron microscopy revealed that GAGA binds to multiple sites as a large oligomer and induces bending of the promoter DNA. Our results indicate a novel mode of DNA binding by GAGA, in which a large GAGA complex binds multiple GAGA elements that are spread out over a region of a few hundred base pairs. We suggest a model in which the promoter DNA is wrapped around a GAGA multimer in a conformation that may exclude normal nucleosome formation. PMID:9927429

  3. Reputation Effects in Social Networks Do Not Promote Cooperation: An Experimental Test of the Raub & Weesie Model

    2016-01-01

    Despite the popularity of the notion that social cohesion in the form of dense social networks promotes cooperation in Prisoner’s Dilemmas through reputation, very little experimental evidence for this claim exists. We address this issue by testing hypotheses from one of the few rigorous game-theoretic models on this topic, the Raub & Weesie model, in two incentivized lab experiments. In the experiments, 156 subjects played repeated two-person PDs in groups of six. In the “atomized interactions” condition, subjects were only informed about the outcomes of their own interactions, while in the “embedded” condition, subjects were informed about the outcomes of all interactions in their group, allowing for reputation effects. The design of the experiments followed the specification of the RW model as closely as possible. For those aspects of the model that had to be modified to allow practical implementation in an experiment, we present additional analyses that show that these modifications do not affect the predictions. Contrary to expectations, we do not find that cooperation is higher in the embedded condition than in the atomized interaction. Instead, our results are consistent with an interpretation of the RW model that includes random noise, or with learning models of cooperation in networks. PMID:27366907

  5. Promotion of cooperation due to diversity of players in the spatial public goods game with increasing neighborhood size

    2014-07-01

    It is well-known that individual diversity is a typical feature within the collective population. To model this kind of characteristics, we propose an evolutionary model of public goods game with two types of players (named as A and B), where players are located on the sites of a square lattice satisfying the periodic boundary conditions. The evolution of the strategy distribution is governed by iterated strategy adoption from a randomly selected neighbor with a probability, which not only depends on the payoff difference between players, but also on the type of the neighbor. For B-type agents, we pose a pre-factor (0cooperators characterizing the promotion of cooperation. Current findings are of utmost importance for us to understand the evolution of cooperation under many real-world circumstances, such as the natural, biological, economic and even social systems.

  6. The psychology of primate cooperation and competition: a call for realigning research agendas.

    PubMed

    Schmelz, Martin; Call, Josep

    2016-01-19

    Cooperation and competition are two key components of social life. Current research agendas investigating the psychological underpinnings of competition and cooperation in non-human primates are misaligned. The majority of work on competition has been done in the context of theory of mind and deception, while work on cooperation has mostly focused on collaboration and helping. The current impression that theory of mind is not necessarily implicated in cooperative activities and that helping could not be an integral part of competition might therefore be rather misleading. Furthermore, theory of mind research has mainly focused on cognitive aspects like the type of stimuli controlling responses, the nature of representation and how those representations are acquired, while collaboration and helping have focused primarily on motivational aspects like prosociality, common goals and a sense of justice and other-regarding concerns. We present the current state of these two bodies of research paying special attention to how they have developed and diverged over the years. We propose potential directions to realign the research agendas to investigate the psychological underpinnings of cooperation and competition in primates and other animals.

    2015-01-01

    The tremendous costs of conflict have made humans resourceful not only at warfare but also at peacemaking. Although third parties have acted as peacemakers since the dawn of history, little is known about voluntary, informal third-party intervention in conflict. Here we introduce the Peacemaker Game, a novel experimental paradigm, to model and study the interdependence between disputants and third parties in conflict. In the game, two disputants choose whether to cooperate or compete and a third party chooses whether or not to intervene in the conflict. Intervention introduces side payments that transform the game disputants are playing; it also introduces risk for the third party by making it vulnerable to disputants’ choices. Six experiments revealed three robust effects: (i) The mere possibility of third-party intervention significantly increases cooperation in interpersonal and intergroup conflicts; (ii) reducing the risk to third parties dramatically increases intervention rates, to everyone’s benefit; and (iii) disputants’ cooperation rates are consistently higher than third parties’ intervention rates. These findings explain why, how, and when self-interested third parties facilitate peaceful conflict resolution. PMID:26038546

    2013-02-01

    We study the coupling dynamics between the evolution of cooperation and the evolution of partnership network on a geographical plane. While agents play networked prisoner's dilemma games, they can dynamically adjust their partnerships based on local information about reputation. We incorporate geographical features into the process of the agent's partner switching and investigate the corresponding effects. At each time step of the coevolution, a random agent can either update his strategy by imitation or adjust his partnership by switching from the lowest reputation partner to the highest reputation one among his neighbors. We differentiate two types of neighbors: geographical neighbors (i.e., the set of agents who are close to the focal agent in terms of geographical distance) and connectivity neighbors (i.e., the set of agents who are close to the focal agent in the partnership network in terms of geodesic distance). We find that switching to either geographical neighbors or connectivity neighbors enhances cooperation greatly in a wide parameter range. Cooperation can be favored in a much stricter condition when agents switch to connectivity neighbors more frequently. However, an increasing tendency of reconnecting to geographical neighbors shortens the geographical distance between a pair of partners on average. When agents consider the cost of geographical distance in adjusting the partnership, they are prone to reconnect to geographical neighbors. PMID:23496584

    CXC-chemokines are involved in the chemotaxis of neutrophils, lymphocytes and monocytes. However, role of these chemokines in tumorigenesis, especially with regard to interaction between tumor and its microenvironment, has not been clearly elucidated. The purpose of this study was to analyze the co-operative role of CXCL8 and CXCL12 in the tumor-stromal interaction in pancreatic cancer (PaCa). Using ELISA and RT-PCR, we initially confirmed the expression of ligands and receptors, respectively, of CXC-chemokines in PaCa and stromal cells. We examined the co-operative role of CXCL8 and CXCL12 in proliferation/invasion of PaCa and human umbilical vein endothelial cells (HUVECs), and in HUVEC tube-formations through tumor-stromal interaction by MTS, Matrigel invasion, and angiogenesis assays, respectively. We detected expression of CXCR4, but not CXCR2, in all PaCa cells and fibroblasts. PaCa cells secreted CXCL8, and fibroblast cells secreted CXCL12. CXCL8 production in PaCa was significantly enhanced by CXCL12, and CXCL12 production in fibroblasts was significantly enhanced by co-culturing with PaCa. CXCL8 enhanced proliferation/invasion of HUVECs but did not promote proliferation/invasion of PaCa. Both recombinant and PaCa-derived CXCL8 enhanced tube formation of HUVECs that were co-cultured with fibroblast cells. CXCL12 enhanced the proliferation/invasion of HUVECs and the invasion of PaCa cells but had no effect on tube formation of HUVEC. We showed that PaCa-derived CXCL8 and fibroblast-derived CXCL12 cooperatively induced angiogenesis in vitro by promoting HUVEC proliferation, invasion, and tube formation. Thus, corresponding receptors CXCR2 and CXCR4 are potential antiangiogenic and antimetastatic therapeutic targets in PaCa. PMID:19035451

    The purpose of this article is to describe and analyze the dynamics of cooperative public health research networks, and their utilization as the principal coordination instrument for a technological development program in a public health research institution. It begins with a few methodological considerations in regard to carrying out surveys and systemizing and analyzing data. Next a brief conceptual explanation of cooperative networks is made along with the characteristics of the program. Then the cooperative networks are described and analyzed, observing the relationships between the various actors that dynamize the program, the presence of IT and communications tools, and the sharing of the techno-scientific base among the projects of cooperative networks. The article concludes by interlacing some considerations about the local appropriation of a conceptual techno-scientific organizational model - the cooperative networks. The creation of a data bank of empirical data, and of local concepts and categories for analyses are considered to be decisive factors for increasing the knowledge acquired through sociology and anthropology about research best practices and administration of biomedical research.

    The essential mycobacterial transcriptional regulators RbpA and CarD act to modulate transcription by associating to the initiation complex and increasing the flux of transcript production. Each of these factors interacts directly with the promoter DNA template and with RNA polymerase (RNAP) holoenzyme. We recently reported on the energetics of CarD-mediated open complex stabilization on the Mycobacterium tuberculosis rrnAP3 ribosomal promoter using a stopped-flow fluorescence assay. Here, we apply this approach to RbpA and show that RbpA stabilizes RNAP-promoter open complexes (RPo) via a distinct mechanism from that of CarD. Furthermore, concentration-dependent stopped-flow experiments with both factors reveal positive linkage (cooperativity) between RbpA and CarD with regard to their ability to stabilize RPo The observation of positive linkage between RbpA and CarD demonstrates that the two factors can act on the same transcription initiation complex simultaneously. Lastly, with both factors present, the kinetics of open complex formation is significantly faster than in the presence of either factor alone and approaches that of E. coli RNAP on the same promoter. This work provides a quantitative framework for the molecular mechanisms of these two essential transcription factors and the critical roles they play in the biology and pathology of mycobacteria.

    Over the past few years interest has been growing in traditional knowledge and indigenous practices worldwide. Recent examination by researchers and anthropologists conjectures that Traditional Ecological Knowledge (TEK) might truly contribute to environmental conservation and protection. TEK is now viewed as a complex, rational approach to adaptive management of natural resources for conservation and resource utilization. Traditional resource management practice is now an appropriate research endeavor but engaging with indigenous people is becoming increasingly difficult as indigenous, traditional people assert their rights to their own knowledge. Can a universal approach be determined for use by researchers to engage traditional practitioners in a dialogue that could reveal information to increase the effectiveness of current resource management, efficient use of natural resources and new information?

    We propose a new pairwise Fermi updating rule by considering a social average payoff when an agent copies a neighbor's strategy. In the update rule, a focal agent compares her payoff with the social average payoff of the same strategy that her pairwise opponent has. This concept might be justified by the fact that people reference global and, somehow, statistical information, not local information when imitating social behaviors. We presume several possible ways for the social average. Simulation results prove that the social average of some limited agents realizes more significant cooperation than that of the entire population.

  12. Basin modeling, methane and nitrogen generation, and migration problems: Industry cooperation with research at KFA Juelich

    SciTech Connect

    Poelchau, H.S.; Frielingsdorf, J.; Krooss, B.

    1995-08-01

    Research definition and selection of projects at the Institute of Petroleum and Organic Geochemistry (KFA Juelich) have always been driven by the need of industry. This poster presents a summary of three studies involving industry collaboration. Gas Generation in the West Siberian Basin and Atmospheric Methane Balance: This collaborative project at KFA Juelich and VNII Geosystems (Moscow) with a Russian gas company (Urengoy Neft Gas Geologiya) is funded by several German gas companies (Ruhrgas, Veba and Wintershall). The objective is the understanding of methane generation and accumulation in the crust, and methane release to the atmosphere. The area chosen for study in NW Siberia contains the largest gas fields on earth and supplies a large portion of natural gas used in Germany. Measurements of soil gas emanation rates and in-flight atmospheric methane concentrations are used to calculate the methane balance between lithosphere and atmosphere and possibly anthropogenic pollution (pipeline leaks, etc.). Nitrogen-Rich Natural Gas in the North German Basin - Origin, Kinetics and Numerical Simulation: Many gas reservoirs in the North German Basin contain high concentration (< 10 to >90%) of nitrogen, making these accumulations non-commercial. Pyrolysis of Carboniferous coals showed that not only methane but also significant amounts of nitrogen are generated from the coaly organic matter. Using these pyrolysis kinetics in a basin modelling study, nitrogen concentrations were predicted which closely correlate with observed nitrogen concentrations. German-Norwegian Geoscientific Cooperation: The main goals of this joint effort between the Norwegian and German petroleum industry and research organizations are to: understand and reconstruct the processes involved in the dynamic evolution of the lithosphere; promote the collaboration of scientists of different background; address open questions of basin evolution and reservoir formation in a common study area (North Sea).

  13. Oxytocin modulates cooperation within and competition between groups: an integrative review and research agenda.

    PubMed

    De Dreu, Carsten K W

    2012-03-01

    The author reviews evidence that hypothalamic release (or infusion) of the neuropeptide oxytocin modulates the regulation of cooperation and conflict among humans because of three reasons. First, oxytocin enables social categorization of others into in-group versus out-group. Second, oxytocin dampens amygdala activity and enables the development of trust. Third, and finally, oxytocin up-regulates neural circuitries (e.g., inferior frontal gyrus, ventromedial prefrontal cortex, caudate nucleus) involved in empathy and other-concern. Consistent with an evolutionary perspective on the functionality of cooperation, it is concluded that oxytocin-motivated cooperation is mostly parochial-it motivates (i) in-group favoritism, (ii) cooperation towards in-group but not out-group members, and (iii) defense-motivated non-cooperation towards threatening outsiders. Thus, in addition to its well-known role in reproduction and pair-bond formation, oxytocin's primary functions include in-group "tend-and-defend." This review concludes with avenues for new research on oxytocin's functions in within-group cooperation and between-group competition. This article is part of a Special Issue entitled Oxytocin, Vasopressin, and Social Behavior. PMID:22227278

  19. Cooperation and conflict in qualitative research: a dialectical approach to knowledge production.

    PubMed

    Enosh, Guy; Ben-Ari, Adital

    2010-01-01

    Our goal with this article is to present a dialectical approach to examining the interaction between researchers and research participants. A dialectical approach maintains that an apparent contradiction at one level might, in fact, be integrated as a synthesis of the two opposing poles at a higher level of conceptual analysis. We claim that a research approach advocating either pole might limit understanding of the complexity of the phenomenon in question. The interaction between researchers and research participants might be conceived of as creating a continuum ranging from cooperation to conflict. We adopt a dialectical perspective, and propose a whole spectrum of interactive styles between cooperation and conflict. Although some of these interactions might be perceived as a hindrance to knowledge production, we treat them as opportunities for the production of knowledge and the enhancement of interests of the study's target population.

  3. Promotion and Reporting of Research from Resource-Limited Settings

    PubMed Central

    Siriwardhana, Chesmal

    2015-01-01

    Driven by global burden of disease and inequalities in health care, research activities in resource-poor settings have radically increased. However, a corresponding increase in reporting of research from these settings has not been observed. This article critically explores the importance of promoting and reporting of health research from resource-poor settings, current trends, and practices, and discusses the key challenges faced by researchers from such settings. These challenges include changing face of open-access (OA) and online publishing, the threat of predatory OA journals, authorship and international partnership ethics, attitudinal problems hindering research reporting, and a lack of alternative publishing spaces. A combined, decisive effort is needed to bridge the gap between research activity and reporting in resource-poor settings. PMID:26396528

  12. Pokemon and MEF2D co-operationally promote invasion of hepatocellular carcinoma.

    PubMed

    Hong, Xin; Hong, Xing-Yu; Li, Tao; He, Cheng-Yan

    2015-12-01

    Hepatocellular carcinoma (HCC) is one of the most deadly human malignancy, and frequent invasion and metastasis is closely associated with its poor prognosis. However, the molecular mechanism underlying HCC invasion is still not completely elucidated. Pokemon is a well-established oncogene for HCC growth, but its contribution to HCC invasion has not been studied yet. In this paper, Pokemon was found to be overexpressed in MHCC-97H HCC cell line, which possesses higher invasiveness. Downregulation of Pokemon abolished the invasion of MHCC-97H HCC cell lines. Pokemon overexpression was able to enhance the invasion of MHCC-97L cells with lower invasiveness. MEF2D, an oncogene promoting the invasion of HCC cells, was further detected to be upregulated and downregulated when Pokemon was overexpressed and silenced, respectively. Online database analysis indicated that one Pokemon recognition site was located within the promoter of MEF2D. Chromatin co-precipitation, luciferase, and qPCR assays all proved that Pokemon can promote the expression of MEF2D in HCC cells. Restoration of MEF2D expression can prevent the impaired invasion of HCC cells with Pokemon silencing, while suppression of MEF2D abolished the effect of Pokemon overexpression on HCC invasion. More interestingly, MEF2D was also found to increase the transcription of Pokemon by binding myocyte enhancer factor 2 (MEF2) sites within its promoter region, implying an auto-regulatory circuit consisting of these two oncogenes that can promote HCC invasion. Our findings can contribute to the understanding of molecular mechanism underlying HCC invasion, and provided evidence that targeting this molecular loop may be a promising strategy for anti-invasion therapy.

    PICH is a SNF2 family DNA translocase that binds to ultra-fine DNA bridges (UFBs) in mitosis. Numerous roles for PICH have been proposed from protein depletion experiments, but a consensus has failed to emerge. Here, we report that deletion of PICH in avian cells causes chromosome structural abnormalities, and hypersensitivity to an inhibitor of Topoisomerase II (Topo II), ICRF-193. ICRF-193-treated PICH(-/-) cells undergo sister chromatid non-disjunction in anaphase, and frequently abort cytokinesis. PICH co-localizes with Topo IIα on UFBs and at the ribosomal DNA locus, and the timely resolution of both structures depends on the ATPase activity of PICH. Purified PICH protein strongly stimulates the catalytic activity of Topo II in vitro. Consistent with this, a human PICH(-/-) cell line exhibits chromosome instability and chromosome condensation and decatenation defects similar to those of ICRF-193-treated cells. We propose that PICH and Topo II cooperate to prevent chromosome missegregation events in mitosis.

  15. Candies to Dye for: Cooperative, Open-Ended Student Activities to Promote Understanding of Electrophoretic Fractionation

    A three-part series of laboratory activities is presented that allows students to learn why electrophoretic separations work and to manipulate the factors that influence the separation process. In the first two exercises, students perform cooperative separations of FD&C dyes from candies utilizing electrophoresis in two buffers of different pH. Students must use package information from one brand of candy and critical thinking to determine the identities of these dyes. Using structural formulas for the dyes the students draw conclusions regarding the effect of charge and molecular mass on separation. The final activity is an open-ended investigation into a student-formulated question. These activities integrate topics in biology and chemistry into activities that interest students and foster a real understanding of the tool of electrophoresis.

    Many girls are not sent to school in Yemen, despite basic education being free as well as compulsory for all children aged 6-15. Aiming to improve girls' enrolment by increasing parental and community involvement, the Japan International Cooperation Agency (JICA) offered a technical cooperation project in June 2005 called Broadening Regional Initiative for Developing Girls' Education (BRIDGE). Phase 1 of this project ran for three and a half years, piloting a participatory school management model supported by school grants in six districts of the Taiz Governorate in the Southwest of Yemen. To find out how successful this approach has been in a traditional society, the authors of this paper analysed the gender parity index (GPI) of the project's pilot schools. Based on data collected at three points in time (in the initial and final years of the project, and two years after the project's end), their findings suggest that interventions in school management which strongly emphasise girls' education can be effective in improving gender parity rather quickly, regardless of the schools' initial conditions. However, the authors also observe that the pilot schools' post-project performance in terms of gender parity is mixed. While the local government allocated budgets for school grants to all pilot schools even after the project's end, training and monitoring activities were cut back. The authors further observe that the variation in performance appears to be significantly correlated with school leaders' initial perceptions of gender equality and with the number of female teachers employed. These findings point to the importance of providing schools with continuous long-term guidance and of monitoring those which implement school improvement programmes.

  17. Using action research to change health-promoting practice.

    PubMed

    Casey, Dympna

    2007-03-01

    Action research was used as a method to develop an educational skills training program focusing on the health education aspect of nurses' health-promoting role. The program was based on the theoretical concepts of the Transtheoretical Model and Motivational Interviewing. Interviews were used to collect the data on a purposive sample of nurses working in an acute hospital ward. Three main themes were identified: using the skills, barriers to implementing the skills, and facilitators of implementing the skills. Most nurses were more aware of health education and health promotion and were able to incorporate the skills learnt and instigated a change in practice. There was evidence, however, that further training was required. This might focus more on helping nurses to use the skills with patients who are very resistant to change and to better recognize health-promoting opportunities. Ways of offering the training program to other health professionals also should be explored.

    Microglial cells are the main HIV-1 targets in the central nervous system (CNS) and constitute an important reservoir of latently infected cells. Establishment and persistence of these reservoirs rely on the chromatin structure of the integrated proviruses. We have previously demonstrated that the cellular cofactor CTIP2 forces heterochromatin formation and HIV-1 gene silencing by recruiting HDAC and HMT activities at the integrated viral promoter. In the present work, we report that the histone demethylase LSD1 represses HIV-1 transcription and viral expression in a synergistic manner with CTIP2. We show that recruitment of LSD1 at the HIV-1 proximal promoter is associated with both H3K4me3 and H3K9me3 epigenetic marks. Finally, our data suggest that LSD1-induced H3K4 trimethylation is linked to hSET1 recruitment at the integrated provirus. PMID:22067449

  19. Cooperative Research Program in Coal-Waste Liquefaction

    The results of a feasibility study for a demonstration plant for the liquefaction of waste plastic and tires and the coprocessing of these waste polymers with coal are presented. The study was conducted by a committee that included nine representatives from the CFFS, six from the U.S. Department of Energy - Federal Energy Technology Center (FETC), and four from Burns and Roe, Inc. The study included: (1) An assessment of current recycling practices, particularly feedstock recycling in Germany; (2) A review of pertinent research, and a survey of feedstock availability for various types of waste polymers; and (3) A conceptual design for a demonstration plant was developed and an economic analysis for various feedstock mixes. The base case for feedstock scenarios was chosen to be 200 tons per day of waste plastic and 100 tons per day of waste tires. For this base case with oil priced at $20 per barrel, the return on investment (ROI) was found to range from 9% to 20%, using tipping fees for waste plastic and tires typical of those existing in the U.S. The most profitable feedstock appeared to waste plastic alone, with a plant processing 300 t/d of plastic yielding ROI's from 13 to 27 %, depending on the tipping fees for waste plastic. Feedstock recycling of tires was highly dependent on the price that could be obtained for recovered carbon. Addition of even relatively small amounts (20 t/d) of coal to waste plastic and/or coal feeds lowered the ROI's substantially. It should also be noted that increasing the size of the plant significantly improved all ROI's. For example, increasing plant size from 300 t/d to1200 t/d approximately doubles the estimated ROI's for a waste plastic feedstock.

  20. Research on multirobot pursuit task allocation algorithm based on emotional cooperation factor.

    Multirobot task allocation is a hot issue in the field of robot research. A new emotional model is used with the self-interested robot, which gives a new way to measure self-interested robots' individual cooperative willingness in the problem of multirobot task allocation. Emotional cooperation factor is introduced into self-interested robot; it is updated based on emotional attenuation and external stimuli. Then a multirobot pursuit task allocation algorithm is proposed, which is based on emotional cooperation factor. Combined with the two-step auction algorithm recruiting team leaders and team collaborators, set up pursuit teams, and finally use certain strategies to complete the pursuit task. In order to verify the effectiveness of this algorithm, some comparing experiments have been done with the instantaneous greedy optimal auction algorithm; the results of experiments show that the total pursuit time and total team revenue can be optimized by using this algorithm.

  20. Genetic dissection of independent and cooperative transcriptional activation by the LysR-type activator ThnR at close divergent promoters.

    Rivas-Marín, Elena; Floriano, Belén; Santero, Eduardo

    2016-04-18

    Regulation of tetralin biodegradation operons is one of the examples of unconventional LysR-type mediated transcriptional regulation. ThnR activates transcription from two divergent and closely located promoters PB and PC. Although ThnR activates each promoter independently, transcription from each one increases when both promoters are together. Mutational analysis of the intergenic region shows that cooperative transcription is achieved through formation of a ThnR complex when bound to its respective sites at each promoter, via formation of a DNA loop. Mutations also defined ThnR contact sites that are important for independent transcriptional activation at each promoter. A mutation at the PB promoter region, which abolishes its independent transcription, does not affect at all PB transcription in the presence of the divergent promoter PC, thus indicating that the complex formed via DNA loop can compensate for the deficiencies in the correct protein-DNA interaction at one of the promoters. Combination of mutations in both promoters identifies a region at PC that is not important for its independent transcription but it is essential for cooperative transcription from both promoters. This work provides new insights into the diversity and complexity of activation mechanisms used by the most abundant type of bacterial transcriptional regulators.

    2012-04-01

    The National Cancer Institute (NCI)-funded cooperative group cancer clinical trial system develops experimental therapies and often collects samples from patients for correlative research. The cooperative group bank (CGB) system maintains biobanks with a current policy not to return research results to individuals. An online survey was created, and 10 directors of CGBs completed the surveys asking about understanding and attitudes in changing policies to consider return of incidental findings (IFs) and individual research results (IRRs) of health significance. The potential impact of the 10 consensus recommendations of Wolf et al. presented in this issue are examined. Reidentification of samples is often not problematic; however, changes to the current banking and clinical trial systems would require significant effort to fulfill an obligation of recontact of subjects. Additional resources, as well as a national advisory board would be required to standardize implementation.

  3. α-Catenin and Vinculin Cooperate to Promote High E-cadherin-based Adhesion Strength*

    Maintaining cell cohesiveness within tissues requires that intercellular adhesions develop sufficient strength to support traction forces applied by myosin motors and by neighboring cells. Cadherins are transmembrane receptors that mediate intercellular adhesion. The cadherin cytoplasmic domain recruits several partners, including catenins and vinculin, at sites of cell-cell adhesion. Our study used force measurements to address the role of αE-catenin and vinculin in the regulation of the strength of E-cadherin-based adhesion. αE-catenin-deficient cells display only weak aggregation and fail to strengthen intercellular adhesion over time, a process rescued by the expression of αE-catenin or chimeric E-cadherin·αE-catenins, including a chimera lacking the αE-catenin dimerization domain. Interestingly, an αE-catenin mutant lacking the modulation and actin-binding domains restores cadherin-dependent cell-cell contacts but cannot strengthen intercellular adhesion. The expression of αE-catenin mutated in its vinculin-binding site is defective in its ability to rescue cadherin-based adhesion strength in cells lacking αE-catenin. Vinculin depletion or the overexpression of the αE-catenin modulation domain strongly decreases E-cadherin-mediated adhesion strength. This supports the notion that both molecules are required for intercellular contact maturation. Furthermore, stretching of cell doublets increases vinculin recruitment and α18 anti-αE-catenin conformational epitope immunostaining at cell-cell contacts. Taken together, our results indicate that αE-catenin and vinculin cooperatively support intercellular adhesion strengthening, probably via a mechanoresponsive link between the E-cadherin·β-catenin complexes and the underlying actin cytoskeleton.

    This paper reports the findings from a quasi-experimental impact evaluation of the Safe Motherhood Promotion Project (SMPP) conducted in the Narsingdi district of Bangladesh. SMPP is a Japanese aid-funded technical cooperation project aimed at developing local capacities to tackle maternal and newborn health problems in rural areas. We assessed whether the project interventions, in particular, community-based activities under the Model Union approach, had a favorable impact on women's access to and knowledge of maternal health care during pregnancy and childbirth. The project comprises a package of interlinked interventions to facilitate safe motherhood practices at primary and secondary care levels. The primary-level activities focused on community mobilization through participatory approaches. The secondary-level activities aimed at strengthening organizational and personnel capacities for delivering emergency obstetric care (EmOC) at district and sub-district level hospitals. The project impact was estimated by difference-in-differences logistic regressions using two rounds of cross-sectional household survey data. The results showed that the project successfully increased the utilization of antenatal visits and postpartum EmOC services and also enhanced women's knowledge of danger signs during pregnancy and delivery. The project also reduced income inequalities in access to antenatal care. In contrast, we found no significant increase in the use of skilled birth attendants (SBA) in the project site. Nonetheless, community mobilization activities and the government's voucher scheme played a complementary role in promoting the use of SBA. PMID:23465202

  12. How can research on plants contribute to promoting human health?

    One of the most pressing challenges for the next 50 years is to reduce the impact of chronic disease. Unhealthy eating is an increasing problem and underlies much of the increase in mortality from chronic diseases that is occurring worldwide. Diets rich in plant-based foods are strongly associated with reduced risks of major chronic diseases, but the constituents in plants that promote health have proved difficult to identify with certainty. This, in turn, has confounded the precision of dietary recommendations. Plant biochemistry can make significant contributions to human health through the identification and measurement of the many metabolites in plant-based foods, particularly those known to promote health (phytonutrients). Plant genetics and metabolic engineering can be used to make foods that differ only in their content of specific phytonutrients. Such foods offer research tools that can provide significant insight into which metabolites promote health and how they work. Plant science can reduce some of the complexity of the diet-health relationship, and through building multidisciplinary interactions with researchers in nutrition and the pathology of chronic diseases, plant scientists can contribute novel insight into which foods reduce the risk of chronic disease and how these foods work to impact human health.

  13. [Research on collaborative innovation in traditional Chinese medicine of China based on patent cooperation network].

    In the situation of global completion, collaborative innovation is becoming increasingly important because its advantage in risk avoiding and innovation efficiency. In order to explore the model of collaborative innovation and its evolution in traditional Chinese medicine of China, the cooperation in traditional Chinese medicine patents of China from 1985 to 2013 has been analyzed by using the method of scientometrics and social network analysis. It is proved that, though the number of grated cooperative patents has increased sharply during the last thirty years, the degree of cooperation innovation in traditional Chinese medicine of China is still not high. Moreover, in spite of the individual subject' s leading role in the past domestic collaborative innovation in traditional Chinese medicine of China, the institutions have been more and more powerful and achieved great improvement. At last, core institutions, represented by universities have played an important role in the collaborative innovation of domestic institutions, because they are key links between many institutions and promote the transferring and diffusion of knowledge.

  14. Cooperative Research Projects in the Microgravity Combustion Science Programs Sponsored by NASA and NEDO

    2000-01-01

    This document contains the results of a collection of selected cooperative research projects between principal investigators in the microgravity combustion science programs, sponsored by NASA and NEDO. Cooperation involved the use of drop towers in Japan and the United States, and the sharing of subsequent research data and findings. The topical areas include: (1) Interacting droplet arrays, (2) high pressure binary fuel sprays, (3) sooting droplet combustion, (4) flammability limits and dynamics of spherical, premixed gaseous flames and, (5) ignition and transition of flame spread across thin solid fuel samples. All of the investigators view this collaboration as a success. Novel flame behaviors were found and later published in archival journals. In some cases the experiments provided verification of the design and behavior in subsequent experiments performed on the Space Shuttle. In other cases, the experiments provided guidance to experiments that are expected to be performed on the International Space Station.

  15. Intronic motif pairs cooperate across exons to promote pre-mRNA splicing

    PubMed Central

    2010-01-01

    Background A very early step in splice site recognition is exon definition, a process that is as yet poorly understood. Communication between the two ends of an exon is thought to be required for this step. We report genome-wide evidence for exons being defined through the combinatorial activity of motifs located in flanking intronic regions. Results Strongly co-occurring motifs were found to specifically reside in four intronic regions surrounding a large number of human exons. These paired motifs occur around constitutive and alternative exons but not pseudo exons. Most co-occurring motifs are limited to intronic regions within 100 nucleotides of the exon. They are preferentially associated with weaker exons. Their pairing is conserved in evolution and they exhibit a lower frequency of single nucleotide polymorphism when paired. Paired motifs display specificity with respect to distance from the exon borders and in constitutive versus alternative splicing. Many resemble binding sites for heterogeneous nuclear ribonucleoproteins. Specific pairs are associated with tissue-specific genes, the higher expression of which coincides with that of the pertinent RNA binding proteins. Tested pairs acted synergistically to enhance exon inclusion, and this enhancement was found to be exon-specific. Conclusions The exon-flanking sequence pairs identified here by genomic analysis promote exon inclusion and may play a role in the exon definition step in pre-mRNA splicing. We propose a model in which multiple concerted interactions are required between exonic sequences and flanking intronic sequences to effect exon definition. PMID:20704715

    Although informal waste collectors are sometimes organized in cooperatives, their working conditions remain extremely precarious and unsafe. The paper discusses the findings of action oriented, participatory qualitative research with several recycling groups in the metropolitan region of São Paulo, Brazil. During workshops with the recyclers mapping, acting, and drawing methods helped reveal health hazards from collection, separation and transportation of recyclable materials. Major health problems relate to chemical and biological hazards, musculoskeletal damage, mechanical trauma and poor emotional wellbeing. The recent federal legislation on solid waste management opens new avenues for the inclusion of recycling cooperatives in selective waste collection. Nevertheless, we express the need to consider the distinctive characteristics and vulnerabilities of recycling groups, when developing safer work environments in these social businesses. We also suggest that the workspace be ergonomically organized and that public awareness campaigns about selective waste collection are conducted regularly to increase the quality of source separation. The introduction of electric hand pushed carts can further reduce health strains. This research has produced a better understanding of the work of the recyclers and related health risks. The interactive qualitative research methodology has allowed for the co-creation and mobilization of specific knowledge on health and safety in recycling cooperatives. PMID:24084672

  20. Promoting undergraduate education through involvement in research in the Geosciences

    The push to involve undergraduates in research is gaining ground in most universities and colleges. Within our geosciences department at Indiana University - Purdue University Fort Wayne (IPFW), undergraduate education is promoted as the faculty in the department involves students in their research projects. All faculty members involve students in their research works. Dating of monazite using energy dispersive x-ray, size-frequency distributions of leopard frogs, structural organization and growth of Silurian chain corals, seepage meters, and wetlands are some of the recent students' projects facilitated by our faculty. Students are involved in either the professor's research project or projects are specifically designed for students using local sites and materials. Physical geology, environmental geology, environmental conservation, wetlands and hydrogeology are some of the courses that I teach. One common thread in all the courses that I explore is water. I involve my upper-level students to observe some aspect of water as it relates to the environment. My students' projects involve the use of local materials (wetlands, sand dunes, river, wells) or sites within a thirty minute drive off campus. Most students appreciate the chance to be involved in research projects. Students have presented the results of their projects at local, regional and national conferences. Also, some students' works have resulted in peer review articles. Involving undergraduates in research projects introduces them to scientific methods, real world learning, being published, and, it also provides the instructor with materials for effective teaching and getting published too. Sample student projects would be presented.
