Regulation of defeat-induced social avoidance by medial amygdala DRD1 in male and female prairie voles

Social interaction with unfamiliar individuals is necessary for species-preserving behaviors such as finding mates and establishing social groups. However, social conflict is a potential negative outcome to interaction with a stranger that can be distressing enough to cause an individual to later avoid interactions with other unfamiliar conspecifics. Unfortunately, stress research using a prominent model of social conflict, social defeat stress, has largely omitted female subjects. This has left a void in the literature regarding social strain on female stress biology and adequate comparison of the effect of sex in stress pathways. The prairie vole (Microtus ochrogaster) exhibits aggressive behavior in both sexes, making voles an attractive candidate to model social defeat in both sexes. This study sought to establish a model of social defeat stress in both male and female prairie voles, characterize behavioral changes in response to this stressor, and investigate the role of dopamine signaling in the response to social defeat stress. Defeated male and female prairie voles displayed social avoidance as well as an increase in the level of dopamine receptor D1 (DRD1) in the medial amygdala (MeA). Pharmacological manipulation of DRD1 signaling in the MeA revealed that increased DRD1 signaling is sufficient to induce a social avoidant state, and could be a necessary component in the defeat-induced social avoidance response. These findings provide the prairie vole as a model of social defeat in both sexes, and implicate the MeA in avoidance of unfamiliar conspecifics after a distressing social encounter.

Emotion’s influence on judgment-formation: Breaking down the concept of moral intuition

ABSTRACTRecent discussions in the field of moral cognition suggest that the relationship between emotion and judgment-formation can be described in three separate ways: firstly, it narrows our attention to a few salient features of a situation to which we ascribe significance; secondly, it opens up the possibility for critical reflection on the moral ends we’ve set up for ourselves; and thirdly, it has no significant effect on moral cognition. It has not yet been explained why emotion plays apparently contradictory roles in moral decision-making, nor what conditions are necessary to prompt an individual to deliberate on how to realize her moral ends. I argue that emotion is one of multiple, potentially conflicting impulses that occur simultaneously in any given experience of moral intuition. If there is conflict between the action toward which emotion draws us and impulses toward other types of behavior, we are prompted to pause and reflect on how to act, whereas if there is no such conflict, extensive deliberation is deemed unnecessary and is forgone. I explore the implications of my internal conflict model for moral cognition by proposing an explanation for Greene’s experimental results which differs from that offered by Greene himself.

A multilevel and dynamic model of intragroup conflict and decision making: application of agent-based modeling

Although intragroup conflict has both multilevel and dynamic natures, less attention has been paid to establishing a holistic model of intragroup conflict that emerges across levels and unfolds over time. To address this research gap, we extend the multilevel view of intragroup conflict (Korsgaard et al. 2008) to develop a multilevel and dynamic model of intragroup conflict that explicitly includes (1) the role of time and (2) the feedback loop to encompass the dynamic aspect of intragroup conflict. We further instantiate the extended model in the context of team decision-making. To achieve this and systematically examine the complex relationships, we use agent-based modeling and simulation (ABMS). We directly investigate how two types of intragroup conflict—task and relationship conflict—interplay with cross-level antecedences, interrelate and develop over time, and affect team outcomes. This study adds to the intragroup conflict research by extending the field with multilevel and dynamic views.

How dominance hierarchies emerge from conflict: A game theoretic model and experimental evidence

We develop a game theoretic model of conflict and empirically test its predictions to study the emergence of social hierarchies in small groups. Previous research shows uncertainty about actors' ability may lead to more conflict; conflict demonstrates actors' ability and establishes relationships of dominance and submissiveness. Since we assume uncertainty regarding ability to be a crucial cause of conflict, we focus on the effects of different information conditions. We posit that actors know the distribution of abilities in their group and vary whether or not they know (1) their own ability and (2) their interaction partners' interaction histories. Our results from a laboratory experiment closely match qualitative model predictions. Most importantly, conflict produces information about actors’ ability, which reduces subsequent conflict. In an exploratory analysis we investigate to what extent gender, social value orientation, risk preferences and a competitive personality account for the quantitative discrepancies between model predictions and subject behavior.

Peace keeping in a model of conflict with foreign investments

PurposeThis paper aims to examine the role of outside peacekeepers in a bilateral conflict.Design/methodology/approachThe authors build upon a trade theoretic framework by incorporating disruptions due to war, which could affect directly the return to investment, both domestic and foreign, and by introducing explicitly peacekeeping forces into the model. Two countries are engaged in a war, with the purpose of capturing capital. A third country plays a dual role: it is the source of investments in the warring countries, and it deploys soldiers on ground for peacekeeping purposes. The authors consider the cases where the levels of foreign investments are exogenous and when they are endogenously determined by free mobility conditions. In the worst case, they find that foreign investment reduces conflict. In the case of endogenous foreign investments, they examine the effect of multilateral agreements where the two warring countries reduce their number of soldiers and the third increases the number of peacekeepers.FindingsThe authors find that the reform benefits all three countries and increases the level of foreign investments. They consider the cases of exogenous and endogenous foreign direct investment (FDI). In the first case, the authors examine the effect of an exogenous increase in FDI on the war equilibrium and find that it reduces the employment of soldiers in the warring countries and increases the size of the peacekeeping force. They also find that the first-best level of peacekeeping is larger than the equilibrium level. When FDI is endogenous, starting from the initial war equilibrium, they also examine the effect of a multilateral agreement in which the size of the peacekeeping force is increased by the third country and the two warring countries agree to reduce their war efforts. The authors find that the reform makes all three countries better off and increases the level of FDI.Originality/valueThe paper uses a theoretical model with third-party interventions in a bilateral war. It intends to shed light on some of the missing economic implications of peacekeeping. The paper introduces explicitly peacekeeping forces into the analysis and introduces a factor that represents a disruption to return on investment in both warring countries. The third country has a dual role; it provides investments in the warring countries and deploys soldiers for peacekeeping. Peacekeeping reduces the disruption mentioned above and affects the employment of soldiers by the warring countries. The authors find that a multilateral agreement in which the two warring countries reduce their war efforts and the third party increases its peacekeeping force can increase welfare in all three countries.

Is party factionalism harmful or beneficial to party development

Purpose The purpose of this paper is to assess the intra-party conflicts in Hong Kong’s Democratic Party (DP) and their implications for broader democratic processes in the territory. It also examines some other thematic issues including: the party’s policy decision-making process, candidate selection, party membership and mergers, and their overall relevance for democratisation in Hong Kong. Design/methodology/approach The study gives a historical review of intra-party conflicts. The concept of factionalism is applied to better understand the DP in Hong Kong’s political space. Findings Hong Kong is unique and popular models of party conflicts are hardly applicable to the country. Intra-party conflict is an obvious, expected conflict because of differences in formation, leadership, manifestoes and ideologies. The present author tries to examine the case with a view to making a novel contribution. Originality/value The study of political factionalism is not uncommon in Hong Kong but this paper intends to study intra-party elite conflicts and self-democratisation of the Hong Kong DP as a case study which is seldom addressed. Consolidation is a possible scenario and its presence is evident when political elites increasingly demonstrate commitment towards creating a democratic regime and when they hold strong beliefs in democratic procedures and institutions as crucial to governing public life.

Mathematical modeling of ethno-social conflicts with the introduction of the control function

In this article, we propose a model of ethno-social conflict based on diffusion equations with the introduction of the control function for such a conflict. Based on the classical concepts of ethno-social conflicts, we propose a characteristic parameter – social distance – that determines the state of society from the point of view of the theory of conflict. A model based on the diffusion equation of Langevin is developed. The model is based on the idea that individuals interact in society through a communicative field – h. This field is induced by every person in a society and serves as a model of the information interaction between individuals. In addition, the control is introduced into the system through the dissipation function. A solution of the system of equations for a divergent diffusion type is given. Using the example of two interacting–conflicting ethnic groups of individuals, we have identified the characteristic patterns of ethno-social conflict in the social system and determined the effect social distance in society has in the development of similar processes with regard to the external influence, dissipation, and random factors. We have demonstrated how the phase portrait of the system qualitatively changes as the parameters of the control function of the ethno-social conflict change. Using the analysis data of the resulting phase portraits, we have concluded that it is possible to control a characteristic area of sustainability for a social system, within which it remains stable and does not become subject to ethno-social conflicts.

Towards a deliberative approach in public health policy making

Abstract The time when public health policies could be based solely on expert opinion has gone. Public opinion has a real impact on the effectiveness of public health policy. However, for complex issues such as vaccination, screening, GMO’s, privacy and data governance, public opinion is divided. How to integrate divided public opinions into a well-structured health policy? In Belgium, as in many other countries, policy makers have started to turn to deliberative processes to guide policy making with citizen involvement, especially in ethically contentious areas. Deliberative processes aim to involve citizens in policy making in a setting where individual opinions and interests are weighed honestly and fairly, so that through well informed deliberation common ground can emerge. Participants are informed by a neutral information package, a variety of experts and facilitated discussions. In a very transparent way, these positions are molded into tailored policy inputs. In Belgium, such initiatives have recently been organized on biobanking, genomics, e-health, reimbursement policies and more. In France, the government is obliged by law to organize a comprehensive deliberative public consultation on bioethical issues every seven years. Especially in areas that require a large degree of trust, a deliberative approach ensures policies that can be supported by people with diverse views. They offer a viable alternative to traditional models of power and conflict that is more suitable to governance in 21st century democracies. They allow citizens to make a meaningful contribution to topics they may not have been familiar with beforehand, but that do touch on their private lives and interests. The most recent Belgian initiative resulted in nine concrete policy inputs for the implementation of genomics in health care, presented directly by the citizens to the Minister of Public Health. The French initiative is the basis for the current review of the law on bioethics in parliament. Key messages Public health issues touch the interests of all citizens: citizen deliberation should be regarded as an important input for public health policies. A deliberative approach enhances public trust, especially in areas of social or ethical contention.

The mechanism of thin filament regulation: Models in conflict?

In a recent JGP article, Heeley et al. (2019. J. Gen. Physiol https://doi.org/10.1085/jgp.201812198) reopened the debate about two- versus three-state models of thin filament regulation. The authors review their work, which measures the rate constant of Pi release from myosin.ADP.Pi activated by actin or thin filaments under a variety of conditions. They conclude that their data can be described by a two-state model and raise doubts about the generally accepted three-state model as originally formulated by McKillop and Geeves (1993. Biophys. J. https://doi.org/10.1016/S0006-3495(93)81110-X). However, in the following article, we follow Plato's dictum that "twice and thrice over, as they say, good it is to repeat and review what is good." We have therefore reviewed the evidence for the three- and two-state models and present our view that the evidence is overwhelmingly in favor of three structural states of the thin filament, which regulate access of myosin to its binding sites on actin and, hence, muscle contractility.

From Insecurity to Secondary Migration: “Bounded Mobilities” of Syrian and Eritrean Refugees in Europe

This paper seeks to analyse Syrian and Eritrean refugees' mobility experience across European borders, in a framework of mobility and insecurity. Drawing on the conflict model of migration, the paper focuses on the effects of migration and asylum policies when these are not in line with refugees’ needs and aspirations. We argue that when the asylum system does not meet with those expectations, insecurity brings into play secondary movements, which occur in a framework of irregularity. The considerations behind this article are motivated by the empirical evidence that both Syrian and Eritrean refugees undertake irregular secondary migration, whilst being within a protection system that most of the times satisfies their asylum claims. This paper is the result of a qualitative research conducted in 2017 through observation, in-depth interviews with Syrian and Eritrean refugees, and consultations with experts and practitioners in Italy, Greece, Germany and Lebanon.

A moderated mediation model of intragroup conflict

PurposeTeamwork is important for firms’ innovation and effectiveness, but often within-team conflicts arise. Prior literature reported inconsistent associations between conflict and team outcomes. This study aims to clarify these relationships and examine if team reflexivity improves outcomes and weakens intragroup conflict tendencies.Design/methodology/approachData were collected through a survey questionnaire of 288 team members working on projects at 41 different high-tech firms in Jordan. The authors then built a model of intragroup conflict effects and used structural equation modeling to test for both direct and indirect effects.FindingsIndirect effects of intragroup conflict were significantly associated with teamwork quality. Teamwork quality was also significantly related to improved team outcomes, and team reflexivity moderated this relationship. Furthermore, it was found that the direct effect of intragroup conflict was not significantly related to either teamwork quality or effectiveness. Finally, results supported the idea that some conflict is required for teams to remain viable, self-critical and innovative.Research limitations/implicationsThis is a cross-sectional study conducted in a single country and business industry, which limits the generalizability of results.Practical implicationsTeam leaders should use reflexivity to create a sense of openness for collaborative interaction to improve group performance and member satisfaction.Originality/valueThis study provides a verified model to determine the circumstances in which conflict benefits team innovation and effectiveness. A central study contribution is that reflexivity reduces the negative impact of intragroup conflict.

Decision conflict drives reaction times and utilitarian responses in sacrificial dilemmas

AbstractIn the sacrificial moral dilemma task, participants have to morally judge an action that saves several lives at the cost of killing one person. According to the dual process corrective model of moral judgment suggested by Greene and collaborators (2001; 2004; 2008), cognitive control is necessary to override the intuitive, deontological force of the norm against killing and endorse the utilitarian perspective. However, a conflict model has been proposed more recently to account for part of the evidence in favor of dual process models in moral and social decision making. In this model, conflict, moral responses and reaction times arise from the interplay between individually variable motivational factors and objective parameters intrinsic to the choices offered. To further explore this model in the moral dilemma task, we confronted three different samples with a set of dilemmas representing an objective gradient of utilitarian pull, and collected data on moral judgment and on conflict in a 4-point scale. Collapsing all cases along the gradient, participants in each sample felt less conflicted on average when they gave extreme responses (1 or 4 in the UR scale). They felt less conflicted on average when responding to either the low- or the high-pull cases. The correlation between utilitarian responses and conflict was positive in the low-pull and negative in the high-pull cases. This pattern of data suggests that moral responses to sacrificial dilemmas are driven by decision conflict, which in turn depends on the interplay between an objective gradient of utilitarian pull and the moral motivations which regulate individual responsiveness to this gradient.

Primal Capital

Although the dynamics of capital are various, one dynamic is inescapably psychical. In this article, I argue in favor of a concept of what I call “primal capital,” in which capital is not only a “factor of production” but also consists of psychical processes. I proceed by way of reconstructing John Maynard Keynes’s account in The General Theory of Employment, Interest, and Money (1936) of the owner of capital’s “propensity to hoard.” Keynes presents a model of psychical conflict under epistemic conditions of uncertainty, in which the owners of capital are perpetually torn between hoarding capital in the money form and long-term investment in wealth-generating economic production. To develop the psychical content of capital, I explore resonances between Keynes’s account of hoarding and Freud’s account of obsessional neurosis.

Radial basis function neural network for head roll prediction modelling in a motion sickness study

<span>Motion Sickness (MS) is the result of uneasy feelings that occurs when travelling. In MS mitigation studies, it is necessary to investigate and measure the occupant’s Motion Sickness Incidence (MSI) for analysis purposes. One way to mathematically calculate the MSI is by using a 6-DOF Subjective Vertical Conflict (SVC) model. This model utilises the information of the vehicle lateral acceleration and the occupant’s head roll angle to determine the MSI. The data of the lateral acceleration can be obtained by using a sensor. However, it is impractical to use a sensor to acquire the occupant’s head roll response. Therefore, this study presents the occupant’s head roll prediction model by using the Radial Basis Function Neural Network (RBFNN) method to estimate the actual head roll responses. The prediction model is modelled based on the correlation between lateral acceleration and head roll angle during curve driving. Experiments have been conducted to collect real naturalistic data for modelling purposes. The results show that the predicted responses from the model are similar with the real responses from the experiment. In future, it is expected that the prediction model will be useful in measuring the occupant’s MSI level by providing the estimated head roll responses.</span>

IN DEFENSE OF PUBLICS: PROJECTION, BIAS, AND CULTURAL NARRATIVES IN SCIENCE AND RELIGION DEBATES

AbstractJohn H. Evans's recent book Morals Not Knowledge is a timely argument to recognize broader social and cultural factors that might impact what U.S. religious publics think about the relationship between science and religion and their attitudes toward science and/or religion. While Evans's focus is primarily on what can be classed as moral issues, this response argues that there are other factors that sit within neither the older epistemic conflict model approach nor a moral conflict model approach that also merit further investigation. There is a significant need for further research that examines the social, psychological, (geo)political, and broader cultural factors shaping people's social identities in relation to science and religion debates. When undertaking such research, we need to be wary of creating a binary between scholarly and public space discourse. Social scientific research in this field should be led by public perceptions, attitudes, and views, not by concepts or frameworks that we project onto them.

Territorial Conflict over Endogenous Rents

I study a model of conflict over territories from which rents are endogenously generated. Territorial conquest affects market power and, thus, rents. As such, there is an endogenous relationship be...

The Elusive Determinants of Civil Wars

Abstract Like the empirical growth literature, the empirical civil war literature has identified few robust determinants. In this paper, I show that the lack of robust estimates is consistent with rational, forward-looking behavior in a simple dynamic conflict model with asymmetric information. The main result is most of the conflict determinants, such as income per capita, inequality, and natural resource revenues, have ambiguous effects on the conflict risk. The ambiguities largely reflect that, when the parameters change, agents re-optimize.

Political Efficacy as a Buffer of the Heightened Risk of Posttraumatic Stress in Disadvantaged Communities.

External collective political efficacy (PE) is an individual's perception of the extent to which the government is responsive to the needs of his or her group or community or to its collective actions. Does PE play a role in the association between exposure to political violence and posttraumatic stress? The current study aimed to examine whether such PE may help explain why exposure to political violence results in posttraumatic stress for some people but not others. Based on the conservation of resource theory, research has found that residents of some types of communities are less likely to suffer from posttraumatic stress when exposed to political violence, due to the economic and psychological resources these communities provide. Political efficacy, as an individual-level factor that relates to the community, may help predict who will suffer more or less posttraumatic stress from exposure to political violence within a given community. Based on a panel study conducted immediately before and after the 2008-2009 Gaza conflict (N = 650) and hierarchical linear modeling analyses, we found that type of community indeed moderated the association between exposure to political violence and posttraumatic stress, Δ-2 log likelihood = 30.4, p < .001. In addition, we found that PE mitigated the psychological distress resulting from exposure to political conflict in disadvantaged communities, Δ-2 log likelihood = 22.8, p < .001. This study not only further untangled the association between exposure and distress during times of war but also identified the role that governments can play in preventing conflict-induced distress beyond offering physical protection.
