Paternal early experiences influence infant development through non-social mechanisms in Rhesus Macaques.

BackgroundEarly experiences influence the developing organism, with lifelong and potentially adaptive consequences. It has recently become clear that the effects of early experiences are not limited to the exposed generation, but can influence physiological and behavioral traits in the next generation. Mechanisms of transgenerational effects of parental early experiences on offspring development are often attributed to prenatal or postnatal parental influence, but recent data suggest that germ-line plasticity may also play a role in the transgenerational effects of early experiences. These non-genetic transgenerational effects are a potentially important developmental and evolutionary force, but the effects of parental experiences on behavior and physiology are not well understood in socially complex primates. In the non-human primate, the rhesus macaque, nursery rearing (NR) is an early life manipulation used for colony management purposes, and involves separating infants from parents early in life. We examined the effects of maternal and paternal early NR on infant rhesus macaque immunity, physiology, and behavior.ResultsWe theorized that differences in behavior or physiology in the absence of parent-offspring social contact would point to biological and perhaps germ-line, rather than social, mechanisms of effect. Thus, all subjects were themselves NR. Male and female infant rhesus macaques (N= 206) were separated from parents and social groups in the first four days of life to undergo NR. These infants differed only in their degree of NR ancestry - whether their dams or sires were themselves NR. At 3-4 months of age, infants underwent a standardized biobehavioral assessment. Factors describing immunity, plasma cortisol, and emotion regulation were generated from these data using factor analysis. Paternal, but not maternal, NR was associated with greater emotionality and higher plasma cortisol, compared with infants born to CONTROL reared fathers.ConclusionsThese data suggest that macaque biobehavioral makeup is strongly influenced by paternal experiences, and via non-social mechanisms

Social Mechanisms and Social Causation

yesThe aim of this paper is to examine the notion of social mechanisms by comparison with the notions of evolutionary and physical mechanisms. It is argued that social mechanisms are based on trends, and not lawlike regularities, so that social mechanisms are different from mechanisms in the natural sciences. Taking as an example of social causation the abolition of the slave trade, the paper argues that social mechanisms should be incorporated in Weber’s wider notion of adequate causation in order to achieve their explanatory purpose

Finding a Mate With No Social Skills

Sexual reproductive behavior has a necessary social coordination component as willing and capable partners must both be in the right place at the right time. While there are many known social behavioral adaptations to support solutions to this problem, we explore the possibility and likelihood of solutions that rely only on non-social mechanisms. We find three kinds of social organization that help solve this social coordination problem (herding, assortative mating, and natal philopatry) emerge in populations of simulated agents with no social mechanisms available to support these organizations. We conclude that the non-social origins of these social organizations around sexual reproduction may provide the environment for the development of social solutions to the same and different problems.Comment: 8 pages, 5 figures, GECCO'1

Autism, the Integrations of 'Difference' and the Origins of Modern Human Behaviour

It is proposed here that the archaeological evidence for the emergence of 'modern behaviour' (160,000-40,000 bp) can best be explained as the rise of cognitive variation within populations through social mechanisms for integrating 'different minds', rather than by the development of a single 'modern human mind'. Autism and the autistic spectrum within human populations are used as an example of 'different minds' which when integrated within society can confer various selective benefits. It is proposed that social mechanisms for incorporating autistic difference are visible in the archaeological record and that these develop sporadically from 160,000 years bp in association with evidence for their consequences in terms of technological innovations, improved efficiency in technological and natural spheres and innovative thinking. Whilst other explanations for the emergence Of modern human behaviour may also contribute to observed changes, it is argued that the incorporation of cognitive differences played a significant role in the technological, social and symbolic expression of 'modern' behaviour

Network Governance at the Firm and Network Level: Goals, Routines, and Social Mechanisms

This article contributes to the general understanding of governance in networks and the achievement of private and common goals. Integrating transaction costs and social network theory, a simple integrated framework is provided for understanding why firms collaborate and under which conditions they establish durable networks that succeed in achieving goals. Network theory is extended by explicitly distinguishing between firm and network level governance, and by identifying governance mechanisms that adapt, coordinate, and safeguard customized exchanges. This way issues as how networks evolve, how they are governed, and ultimately, how collective outcomes might be generated can be better comprehended. This is especially relevant to policy planners and those having a perspective that goes beyond the performance of individual organizations.network governance, social network theory, governance mechanisms., Food Consumption/Nutrition/Food Safety, Food Security and Poverty, Industrial Organization, Research Methods/ Statistical Methods,

Finding influential spreaders from human activity beyond network location

Most centralities proposed for identifying influential spreaders on social networks to either spread a message or to stop an epidemic require the full topological information of the network on which spreading occurs. In practice, however, collecting all connections between agents in social networks can be hardly achieved. As a result, such metrics could be difficult to apply to real social networks. Consequently, a new approach for identifying influential people without the explicit network information is demanded in order to provide an efficient immunization or spreading strategy, in a practical sense. In this study, we seek a possible way for finding influential spreaders by using the social mechanisms of how social connections are formed in real networks. We find that a reliable immunization scheme can be achieved by asking people how they interact with each other. From these surveys we find that the probabilistic tendency to connect to a hub has the strongest predictive power for influential spreaders among tested social mechanisms. Our observation also suggests that people who connect different communities is more likely to be an influential spreader when a network has a strong modular structure. Our finding implies that not only the effect of network location but also the behavior of individuals is important to design optimal immunization or spreading schemes

Mechanistic explanations and components of social mechanisms

The past two decades have witnessed an increase in interest in social mechanisms and mechanistic explanations of social macro-phenomena. This paper addresses the question of what the components of social mechanisms in mechanistic explanations of social macro-phenomena must be. Analytical sociology’s initial position and the main new proposals by analytical sociologists are discussed. It is argued that all of them are faced with outstanding difficulties. Subsequently, a minimal requirement regarding the components of social mechanisms is introduced. It is held that a component of a social mechanism in a mechanistic explanation of a social macro-phenomenon must not have the explanandum phenomenon as a part of it

Incorporating social mechanisms in energy decarbonisation modelling

The achievement of national pledges that are compatible with the Paris Agreements warming limit of 1.5C is a massive challenge, as it requires not only an acceleration of technological innovation, but also a socio-economic and cultural transformation. Reducing uncertainties demands a better integration of behavioural evolutions in models exploring future energy pathways, including non-monetary barriers and drivers to technology diffusion. This study provides suggestions on incorporating social mechanisms of change such as resistance to change and the diffusion of environmental values into a UK-focused probabilistic energy system model, with a focus on people's attitudes towards residential heating technologies. We also offer a comprehensive literature review on interdisciplinary energy transitions modelling and exploratory scenarios embedding climate risks perceptions. We argue that efficient policy-making to meeting net-zero emissions targets must fully embrace whole-system approaches, support the more constrained segments of society, and account for interconnected socio-political factors

LEADERS’ PORTFOLIO: PSYCHO-SOCIAL MECHANISMS AUGMENTING CREATIVITY

Purpose: There is a consensus that creativity is one of the pivotal characteristics of a contemporary leader. There are however no publications indicating how the leader may augment own, as well as the team’s creativity. The article fills this gap, focusing on the type of creativity which is a long-lasting propensity – as opposed to one creative act usually considered in literature.Approach: The article is based on literature review and case studies analysis. After presenting cases illustrating the role of and need for creativity as a longitudinal propensity, a literature analysis follows delineating the mechanisms regulating creativity. We outline the role of brain plasticity in establishing the process of “being creative” as an enduring characteristic, as well as the ambient factors augmenting creativity.Findings: We focus on how to sustain a lasting creative state of mind (as opposed to performing single creative acts) and examine the factors that maintain the creative drive. We look at affective, cognitive and ambient mechanisms that enhance creativity. We specifically look at the role of joy (affective), distance (cognitive) and ambient factors (horizontal networks). We also review several techniques for enhancing teams’ creativity and conclude with recommendations for further studies.Implications: The article provides information useful for leaders and their teams, delineating ways of enhancing creativity.Value/Originality: The article presents a new approach to creativity as enduring phenomenon and to ways of augmenting creativity
