Spectacular pehnomena and limits to rationality in genetic and cultural evolution

In studies of both animal and human behaviour, game theory is used as a tool for understanding strategies that appear in interactions between individuals. Game theory focuses on adaptive behaviour, which can be attained only at evolutionary equilibrium. Here we suggest that behaviour appearing during interactions is often outside the scope of such analysis. In many types of interaction, conflicts of interest exist between players, fueling the evolution of manipulative strategies. Such strategies evolve out of equilibrium, commonly appearing as spectacular morphology or behaviour with obscure meaning, to which other players may react in non-adaptive, irrational way approach, and outline the conditions in which evolutionary equilibria cannot be maintained. Evidence from studies of biological interactions seems to support the view that behaviour is often not at equilibrium. This also appears to be the case for many human cultural traits, which have spread rapidly despite the fact that they have a negative influence on reproduction

Do Facework Behaviors Matter During Conflicts Among Online Discussion Team Members?

According to researchers, face is an important possession carried by individuals into interactions with others. Face has been studied in diverse areas such as: politeness, compliance gaining, emotional discourse, negotiations, face-negotiation theory, and conflict. Perhaps because of its value, face can be vulnerable during conflict situations. Facework behaviors are the communicative strategies that people use during conflicts to protect face (theirs or others), threaten others\u27 face, and to avoid or resolve conflicts. So far, studies about facework behaviors have focused on face-to-face interactions. Preliminary studies have shown: a. facework behaviors may affect the outcomes of online discussion teams, b. sex may play a role in the relationship between facework behaviors and online discussion outcomes, and c. conflicts among online discussion team members may influence discussion outcomes. This research explores more completely the role that facework behaviors play during conflicts, their influence on online discussion outcomes, and the role that sex plays in these matters. Data gathered from surveys and transcripts of participants\u27 online discussion postings show that facework behaviors: a. influence conflict levels, b. influence the outcomes of the online discussion teams, and c. play a moderating role on the relationship between conflicts and online discussion outcomes. They also indicate that sex plays a moderating role in these relationships. Moreover, this study shows that the typology of facework behaviors, originally developed to describe face-related aspects of face-to-face interactions, has value in understanding online discussions

The Political Economy of the Rise and Decline of Developmental States

Based on a classical political economy, on Latin American structuralism, and on Gramscian perspective about the state this paper argues that national economic strategies are formed by particular interactions between institutions and economic structures and evolve according to social conflicts in a non neutral international environment. This idea is explored to interpret the rise of the developmental state in some national development strategies experienced by peripheral countries during the highest convergence period of the Golden Age and its crisis and redefinitions during the greatest divergence phase and neoliberal reforms of the last two decades of the 20th century.Political economy, Developmental state, Economic development

Adolescents with Attention Deficit Hyperactivity Disorder: Mother-adolescent interactions, family beliefs and conflicts, and maternal psychopathology.

A group of 83 adolescents with attention deficit hyperactivity disorder (ADHD) were subdivided into those with ADHD alone (n = 27) and those with ADHD and oppositional defiant disorder (ADHD/ODD, n = 56). They were compared to each other and a community control group (n = 77) on measures of family conflicts, family beliefs, maternal adjustment, and observations of mother-adolescent interactions during both a neutral and conflict discussion. Both ADHD groups had more topics on which there was conflict and more angry conflicts at home than control adolescents on parent reports. Only the ADHD/ODD adolescents reported more such conflicts, endorsed more extreme and unreasonable beliefs about their parent-teen relations, and demonstrated greater negative interactions during a neutral discussion than the control teenagers. Similarly, only mothers of the ADHD/ODD teens displayed greater negative interactions during a neutral discussion, more extreme and unreasonable beliefs about their parent-teen relations, greater personal distress, and less satisfaction in their marriages than the mothers in the control group. Most findings for the ADHD only group were between the control group and the group with mixed ADHDIODD but did not differ from either group. Results imply that it is the combination of ODD symptoms with those of ADHD that is associated with the greater-than-normal conflicts, anger, poor communications, unreasonable beliefs, and negative interactive styles seen in ADHD adolescents. These same characteristics typify their mothers' interactions as well such that both the adolescents' ODD symptoms and maternal psychological distress (hostility) make unique contributions to the degree of conflict and anger in the parent-teen relations of ADHD adolescents

Effect of maternal panic disorder on mother-child interaction and relation to child anxiety and child self-efficacy

To determine whether mothers with panic disorder with or without agoraphobia interacted differently with their children than normal control mothers, 86 mothers and their adolescents (aged between 13 and 23 years) were observed during a structured play situation. Maternal as well as adolescent anxiety status was assessed according to a structured diagnostic interview. Results showed that mothers with panic disorder/agoraphobia showed more verbal control, were more criticizing and less sensitive during mother-child interaction than mothers without current mental disorders. Moreover, more conflicts were observed between mother and child dyadic interactions when the mother suffered from panic disorder. The comparison of parenting behaviors among anxious and non-anxious children did not reveal any significant differences. These findings support an association between parental over-control and rejection and maternal but not child anxiety and suggest that particularly mother anxiety status is an important determinant of parenting behavior. Finally, an association was found between children’s perceived self-efficacy, parental control and child anxiety symptoms

Group composition effects on aggressive interpack interactions of gray wolves in Yellowstone National Park

Knowledge of characteristics that promote group success during intraspecific encounters is key to understanding the adaptive advantages of sociality for many group-living species. In addition, some individuals in a group may be more likely than others to influence intergroup conflicts, a relatively neglected idea in research on social animals. Here we use observations of aggressive interactions between wolf (Canis lupus) packs over an extended period and use pack characteristics to determine which groups had an advantage over their opponents. During 16 years of observation in Yellowstone National Park from 1995 to 2010, we documented 121 interpack aggressive interactions. We recorded pack sizes, compositions, and spatial orientation related to residency to determine their effects on the outcomes of interactions between packs. Relative pack size (RPS) improved the odds of a pack displacing its opponent. However, pack composition moderated the effect of RPS as packs with relatively more old members (\u3e6.0 years old) or adult males had higher odds of winning despite a numerical disadvantage. The location of the interaction with respect to pack territories had no effect on the outcome of interpack interactions. Although the importance of RPS in successful territorial defense suggests the evolution and maintenance of group living may be at least partly due to larger packs’ success during interpack interactions, group composition is also an important factor, highlighting that some individuals are more valuable than others during interpack conflicts

THE LION AND THE CAT: HOW DO CHILD SOLDIERS SHAPE CONTEMPORARY PEACE OPERATIONS?

Armed conflicts and insurgencies today have adopted ruthless tactics of warfare by coercively recruiting child soldiers. Child soldiers play many roles during armed conflicts, creating security concerns for peace and stability in the international community. This study explores the social, physical, and psychological impact of child soldiers on peacekeepers and communities during and after conflict. It examines the three levels of risk (low, medium, and high) related to the use of force in interactions between child soldiers and members of the military and peacekeeping forces. Furthermore, the study assesses how lower-risk-level interactions can escalate to life-threatening situations. Drawing on relevant international law, literature by subject matter experts, and the author’s personal experience in peacekeeping operations, the research discusses how child soldiers shape contemporary peace support operations using Sierra Leone’s past civil war as a case that involved varieties of UN and non-UN peacekeeping efforts. Finally, the study makes recommendations to policymakers aimed to thwart efforts to recruit children and prevent further interactions between peacekeepers and children during all stages of conflict.Major, Sierra Leone ArmyApproved for public release.

Analyzing the humorous communicative interactions during the wartimes in Aceh

Prolonged armed conflicts between the Government of Indonesia and the Free Aceh Movement/Gerakan Aceh Merdeka (GAM) happened from 1976 to 2005. The three-decade-vertical political conflicts have received worldwide attention in research, except its humorous sides. This study attempted to capture the types and styles of humor within the memories of Aceh society. To do so, this qualitative study used interviews and document analysis to interview 20 Acehnese people from five districts in Aceh province who experienced the vertical wars in Aceh and analyze written resources. The research found that there are many types and styles of humor that happened unintentionally as the result of the speakers’ mistranslating and miscode-mixing from Acehnese language to Indonesian language during unexpected interactions. Most of the humor occurring during the wars in Aceh fall into the incongruity theory, the verbal pun style, and the self-enhancing style. The findings of the study provide insights on the humorous side of the long wars through communicative interactions in Aceh that are useful to relieve tension when remembering the bitterness of the wars

PYTHIA and the preoccupied proton

The PYTHIA Monte Carlo (PMC) has been applied broadly to simulations of high-energy $p$-$p$ and $p$-$\bar p$ collisions. The PMC is based on several assumptions, such as that most hadrons result from jet production (multiple parton interactions or MPIs), that $p$-$p$ centrality is relevant and that color reconnection (CR) strongly influences fragmentation to jets. An alternative description is provided by the two-component (soft + hard) model (TCM) of hadron production. TCM analysis of $p$-Pb ensemble-mean-$p_t$ data reveals centrality trends quite different from those estimated via a geometric Glauber model based on the eikonal approximation. Glauber estimates of binary-collision number are three times TCM estimates. Detailed study of $p$-Pb data conflicts with a basic Glauber assumption -- that a projectile proton may interact simultaneously with multiple target nucleons. Instead, in both $p$-$p$ and $p$-A collisions, a $p$-N collision once initiated is exclusive of other possible interactions (during that collision), and within the collision any pair of participant partons may interact -- a $p$-N collision is thus "all or nothing." In this presentation the PMC is challenged by an assortment of contradictory data, and evidence for $p$-N exclusivity is reviewed to make a case for the "preoccupied proton" of the title.Comment: 10 pages, 7 figures, Proceedings of XLVIII International Symposium on Multiparticle Dynamic

Combating Religious Divisiveness with Cosmopolitanism

This thesis examines cosmopolitanism as a potential means of preventing conflicts between religious groups. In order to effectively determine what cosmopolitanism might be capable of accomplishing in this regard, religious interactions are examined during two major historical events – the Crusades and World War II. This thesis studies both of these events with the intention of identifying cosmopolitan behaviors and non-cosmopolitan behaviors, and determining how these behaviors impacted the relationships between the religious groups involved. Later, obstacles that stand between religious groups and cosmopolitanism are acknowledged, and methods of overcoming those obstacles are discussed. This thesis finds that the proceedings of the two aforementioned events suggest that cosmopolitanism does indeed possess the potential to reduce the frequency and severity of interreligious conflicts. However, it concedes that cosmopolitanism might be incapable of preventing such conflicts before certain changes are made to some modern religions
