The Relationship

A key goal of social neuroscience is to understand the relationship between the neural activity of socially interacting individuals. Decades of research have focused on a single aspect of that relationship: the similarity in neural activity across brains. Here we instead asked how neural activity differs between brains, and how that difference evolves alongside activity patterns shared between brains. Applying this framework to pairs of bats engaged in spontaneous social interactions revealed two complementary phenomena characterizing the inter-brain neural relationship: fast “inter-brain catch-up” unfolding in parallel with slow activity covariation across brains. A model reproduced these observations, generated multiple predictions that we confirmed using experimental data, and provided testable hypotheses for studying the inter-brain relationship in larger social groups. Together, the data and model suggest a parsimonious computational mechanism—opposite feedback to neural activity components reflecting interbrain difference and similarity—that unifies diverse aspects of the inter-brain neural relationship.

The Relationship

Although consistent behavioural differences between individuals (i.e. personality variation) are now well established in animals, these differences are not always expressed when individuals interact in social groups. This can be key in important social dynamics such as leadership, which is often positively related to personality traits such as boldness. Individuals consistently differ in how social they are (their sociability), so if other axes of personality variation, such as boldness, can be suppressed during social interactions, this suppression should be stronger in more sociable individuals. We measured boldness (latency to leave a refuge when alone) and sociability (time spent with a conspecific) in three-spined sticklebacks ( Gasterosteus aculeatus ) and tested the boldness–leadership association in pairs of these fish. Both boldness and sociability were repeatable, but were not correlated. When splitting the data between the 50% most sociable and 50% less sociable fish, boldness was more strongly associated with leadership in less rather than more sociable individuals. This is consistent with more sociable fish conforming to their partner's behaviour due to their greater social tendency. One axis of personality variation (sociability) can thus modulate the relationship between others (boldness and leadership), with potential implications for selection on personality variation in social animals.

The present article is a bibliographic research on the integrative literature review mode, on social neuroscience, social cognition and Schadenfreude in intergroup relations. The objective was to identify an understanding of how social neuroscience could contribute and offer new insights into the Social Cognition (eg: stereotypes, prejudice, social comparison), the Schadenfreude and neural process in social interactions. From the criteria of location and selection, 28 articles published in the databases PubMed, Web of Science and SCIELO between 2006 and 2015 were retrieved, using keywords: Schadenfreude and Social Cognition, Schadenfreude and Brain, Schadenfreude and Neural, Schadenfreude and Neuro, Schadenfreude and Intergroup relation. Generally, such articles are descriptive and qualitative, and they developed mostly with the samples that showed no pathology or disease in samples. A link it showed between the Schadenfreude and the neural interface, as well as social cognition and neuronal relationship with the aim of understanding how interact in a social context. It is perceived from the approach on the subject a better understanding of social behavior in real life through neurocognitive mechanisms offering evidence in the relationship between Schadenfreude, social neuroscience and social cognition.

The results of an empirical study of socio-demographic factors of youth social activity are pre-sented. The aim of the study is to determine the relationship between the significance of social activ-ity forms and age, as well as a comparison of their importance in social groups identified by the criteria of gender, marital status, and educational level. As a result of correlation and comparative analysis using the Pearson and t-student criteria, it was revealed that with increasing age, the value of religious activi-ty increases and the importance of altruistic, Inter-net, spiritual and subcultural forms of youth activity decreases; women value the importance of the In-ternet, social, economic, educational and spiritual forms of activity higher than men; a family contrib-utes to the growth of altruistic, socio-economic, educational and spiritual forms of activity; the high-er level of education means the higher social activity of the subject, which can be realized in wide areas of social interactions.

Stress And Health

Abstract. Stress-related stimuli may be presented outside of awareness and may ultimately influence health by causing repetitive increases in physiological parameters, such as blood pressure (BP). In this study, we aimed to corroborate previous studies that demonstrated BP effects of subliminally presented stress-related stimuli. This would add evidence to the hypothesis that unconscious manifestations of stress can affect somatic health. Additionally, we suggest that these findings may be extended by measuring affective changes relating to these physiological changes, using measures for self-reported and implicit positive and negative affectivity. Using a repeated measures between-subject design, we presented either the prime word “angry” ( n = 26) or “relax” ( n = 28) subliminally (17 ms) for 100 trials to a student sample and measured systolic and diastolic BP, heart rate (HR), and affect. The “angry” prime, compared to the “relax” prime, did not affect any of the outcome variables. During the priming task, a higher level of implicit negative affect (INA) was associated with a lower systolic BP and diastolic BP. No association was found with HR. Self-reported affect and implicit positive affect were not related to the cardiovascular (CV) activity. In sum, anger and relax primes elicited similar CV activity patterns, but implicit measures of affect may provide a new method to examine the relationship between (unconscious) stress and health.

<p>A mixed-integer nonlinear programming (MINLP) formulation for symbolic regression was proposed to identify physical models from noisy experimental data. The formulation was tested using numerical models and was found to be more efficient than the previous literature example with respect to the number of predictor variables and training data points. The globally optimal search was extended to identify physical models and to cope with noise in the experimental data predictor variable. The methodology was coupled with the collection of experimental data in an automated fashion, and was proven to be successful in identifying the correct physical models describing the relationship between the shear stress and shear rate for both Newtonian and non-Newtonian fluids, and simple kinetic laws of reactions. Future work will focus on addressing the limitations of the formulation presented in this work, by extending it to be able to address larger complex physical models.</p><p><br></p>

The Relationship

The social policy of a country is a set of specific activities aimed at regulating the social relations between different in their social status subjects. This approach to clarifying social policy is also called functional and essentially addresses social policy as an activity to regulate the relationship of equality or inequality in society. It provides an opportunity to look for inequalities in the economic positions of individuals in relation to ownership, labor and working conditions, distribution of income and consumption, social security and health, to look for the sources of these inequalities and their social justification or undue application.The modern state takes on social functions that seek to regulate imbalances, to protect weak social positions and prevent the disintegration of the social system. It regulates the processes in society by harmonizing interests and opposing marginalization. Every modern country develops social activities that reflect the specifics of a particular society, correspond to its economic, political and cultural status. They are the result of political decisions aimed at directing and regulating the process of adaptation of the national society to the transformations of the market environment. Social policy is at the heart of the development and governance of each country. Despite the fact that too many factors and problems affect it, it largely determines the physical and mental state of the population as well as the relationships and interrelationships between people. On the other hand, social policy allows for a more global study and solving of vital social problems of civil society. On the basis of the programs and actions of political parties and state bodies, the guidelines for the development of society are outlined. Social policy should be seen as an activity to regulate the relationship of equality or inequality between different individuals and social groups in society. Its importance is determined by the possibility of establishing on the basis of the complex approach: the economic positions of the different social groups and individuals, by determining the differences between them in terms of income, consumption, working conditions, health, etc .; to explain the causes of inequality; to look for concrete and specific measures to overcome the emerging social disparities.

At this point the chapters catch up in time with the events narrated in the prologue. Chapter 5 begins by recounting George Nicholls’ discoveries in June 1921. The detective searched the Goodings’ and Swans’ houses and took from the Swans’ a quantity of blotting paper that bore the imprint of some of the libels. Rose Gooding’s handwriting was very different. When Sir Archibald Bodkin, the Director of Public Prosecutions, read Nicholls’ report, he declared that this was fundamentally ‘a case of handwriting’. How, Bodkin mused, could an ‘uneducated’ woman develop such a distinctive style? The chapter uses Bodkin’s reaction to Rose Gooding’s letters, the evidence provided by spelling and misspelling, and the inventory of writing paraphernalia in the Gooding and Swan households, to explore the relationship between popular literacy and agency, engaging with the recent work of Jane Caplan and Patrick Joyce.

How to predict the relationship among particle size and among product size, to establish the relationship between the granularity and working parameters in the process of grinding and to determine the optimum operating parameters. With proposing BS squeeze crush model by L. Bass and the idea of roll surface division as the material uneven extrusion force are adopted. Based on field experiments the experimental data is analyzed, the select function and the breakage functions are fitted with MATLAB software, and obtaining their model. The comminution model is determined by the roller division. We obtain the model parameter through the experimental data. Through model analysis shows: the relationship between particle breakage and energy absorption, namely the smaller size of the same power, the lower broken; the breakage diminishes with the decrease of particle size ratio and it will be tending to a small constant when the smaller particle size ratio. The breakage functions rapidly decrease within ratio of between 0.2-0.7. This shows: the energy consumption will rapidly increase when the particle size of less than 0.2 in broken; the selection diminish with the decrease of particle size. Pressure (8-9MPa) should be the most appropriate value.
