    Linear dominance hierarchies, which are common in social animals, can profoundly influence access to limited resources, reproductive opportunities and health. In spite of their importance, the mechanisms that govern the dynamics of such hierarchies remain unclear. Two hypotheses explain how linear hierarchies might emerge and change over time. The ‘prior attributes hypothesis’ posits that individual differences in fighting ability directly determine dominance ranks. By contrast, the ‘social d...

    Full Text Available Different aspects of sociality bear considerable weight on the individual- and group-level welfare of captive nonhuman primates. Social Network Analysis (SNA is a useful tool for gaining a holistic understanding of the dynamic social relationships of captive primate groups. Gaining a greater understanding of captive chimpanzees through investigations of centrality, preferred and avoided relationships, dominance hierarchy, and social network diagrams can be useful in advising current management practices in sanctuaries and other captive settings. In this study, we investigated the dyadic social relationships, group-level social networks, and dominance hierarchy of seven chimpanzees (Pan troglodytes at Chimpanzee Sanctuary Northwest. We used focal-animal and instantaneous scan sampling to collect 106.75 total hours of associative, affiliative, and agonistic data from June to September 2016. We analyzed our data using SOCPROG to derive dominance hierarchies and network statistics, and we diagrammed the group's social networks in NetDraw. Three individuals were most central in the grooming network, while two others had little connection. Through agonistic networks, we found that group members reciprocally exhibited agonism, and the group's dominance hierarchy was statistically non-linear. One chimpanzee emerged as the most dominant through agonism but was least connected to other group members across affiliative networks. Our results indicate that the conventional methods used to calculate individuals' dominance rank may be inadequate to wholly depict a group's social relationships in captive sanctuary populations. Our results have an applied component that can aid sanctuary staff in a variety of ways to best ensure the improvement of group welfare.

  7. A dominance hierarchy of auditory spatial cues in barn owls.

    Full Text Available Barn owls integrate spatial information across frequency channels to localize sounds in space.We presented barn owls with synchronous sounds that contained different bands of frequencies (3-5 kHz and 7-9 kHz from different locations in space. When the owls were confronted with the conflicting localization cues from two synchronous sounds of equal level, their orienting responses were dominated by one of the sounds: they oriented toward the location of the low frequency sound when the sources were separated in azimuth; in contrast, they oriented toward the location of the high frequency sound when the sources were separated in elevation. We identified neural correlates of this behavioral effect in the optic tectum (OT, superior colliculus in mammals, which contains a map of auditory space and is involved in generating orienting movements to sounds. We found that low frequency cues dominate the representation of sound azimuth in the OT space map, whereas high frequency cues dominate the representation of sound elevation.We argue that the dominance hierarchy of localization cues reflects several factors: 1 the relative amplitude of the sound providing the cue, 2 the resolution with which the auditory system measures the value of a cue, and 3 the spatial ambiguity in interpreting the cue. These same factors may contribute to the relative weighting of sound localization cues in other species, including humans.

    Dominance hierarchy influences the life quality of social animals, and its definition should in principle be based on the outcome of agonistic interactions. However, defining and comparing the dominance profile of social groups is difficult due to the different dominance measures used and because no one measure explains it all. We applied different analytical methods to winner-loser sociomatrices to determine the dominance profile of five groups of wild lemurs (species: Lemur catta, Propithecus verreauxi, and Eulemur rufus x collaris) from the Berenty forest (Madagascar). They are an excellent study model because they share the same habitat and an apparently similar dominance profile: linear hierarchy and female dominance. Data were collected over more than 1200 h of observation. Our approach included four steps: (1) by applying the binary dyadic dominance relationship method (I&SI) on either aggressions or supplant sociomatrices we verified whether hierarchy was aggression or submission based; (2) by calculating normalized David's scores and measuring steepness from aggression sociomatrices we evaluated whether hierarchy was shallow or steep; (3) by comparing the ranking orders obtained with methods 1 and 2 we assessed whether hierarchy was consistent or not; and (4) by assessing triangle transitivity and comparing it with the linearity index and the level of group cohesion we determined if hierarchy was more or less cohesive. Our results show that L. catta groups have got a steep, consistent, highly transitive and cohesive hierarchy. P. verreauxi groups are characterized by a moderately steep and consistent hierarchy, with variable levels of triangle transitivity and cohesion. E. rufus x collaris group possesses a shallow and inconsistent hierarchy, with lower (but not lowest) levels of transitivity and cohesion.

  11. Adolescent male chimpanzees do not form a dominance hierarchy with their peers.

    Dominance hierarchies are a prominent feature of the lives of many primate species. These hierarchies have important fitness consequences, as high rank is often positively correlated with reproduction. Although adult male chimpanzees strive for status to gain fitness benefits, the development of dominance relationships is not well understood. While two prior studies found that adolescent males do not display dominance relationships with peers, additional research at Ngogo in Kibale National Park, Uganda, indicates that adolescents there form a linear dominance hierarchy. These conflicting findings could reflect different patterns of rank acquisition across sites. An alternate possibility arises from a recent re-evaluation of age estimates at Ngogo and suggests that the report describing decided dominance relationships between adolescent males may have been due to the accidental inclusion of young adult males in the sample. To investigate these issues, we conducted a study of 23 adolescent male chimpanzees of known age during 12 months at Ngogo. Adolescent male chimpanzees exchanged pant grunts, a formal signal of submission, only 21 times. Recipients of pant grunts were late adolescent males, ranging between 14 and 16 years old. In contrast, younger adolescent males never received pant grunts from other males. Aggression between adolescent males was also rare. Analysis of pant grunts and aggressive interactions did not produce a linear dominance hierarchy among adolescent males. These data indicate that adolescent male chimpanzees do not form decided dominance relationships with their peers and are consistent with the hypothesis that the hierarchy described previously at Ngogo resulted from inaccurate age estimates of male chimpanzees. Because dominance relationships develop before adulthood in other primates, our finding that adolescent male chimpanzees do not do so is surprising. We offer possible explanations for why this is the case and suggest future studies

    Linear hierarchies, the classical pecking-order structures, are formed readily in both nature and the laboratory in a great range of species including humans. However, the probability of getting linear structures by chance alone is quite low. In this paper we investigate the two hypotheses that are proposed most often to explain linear hierarchies: they are predetermined by differences in the attributes of animals, or they are produced by the dynamics of social interaction, i.e., they are self-organizing. We evaluate these hypotheses using cichlid fish as model animals, and although differences in attributes play a significant part, we find that social interaction is necessary for high proportions of groups with linear hierarchies. Our results suggest that dominance hierarchy formation is a much richer and more complex phenomenon than previously thought, and we explore the implications of these results for evolutionary biology, the social sciences, and the use of animal models in understanding human social organization.

  13. Factors influencing the establishment of dominance hierar-chies of the grey triggerfish Balistes capriscus

    Full Text Available Unlike other balistids, grey triggerfish Balistes capriscus occur in social groups in subtropical reef assemblages and have been noted to cooperate in capturing large crustacean prey. The objective of this study were to determine the structure of dominance hierarchies of these social groups and the factors that influence hierarchies of wild-caught grey triggerfish in a naturalistic setting. From observations of four groups of triggerfish (n = 19 fish in both dyad and group (4 – 5 fish settings, we provide a description of triggerfish behaviors and coloration patterns and an explanation of the social context in which suites of behaviors are used by dominant, middle-ranking, and subordinate fish. Sixteen behaviors and nine coloration patterns were noted for grey triggerfish. Grey triggerfish groups form linear hierarchies in both dyads and groups as measured by Landau’s Index of Linearity (h = 1.0 for Groups 1, 3, and 4 and h = 0.95 for Group 2 in dyads; h = 1.0 for all groups in group settings. Dyadic hierarchies, however, were not necessarily good predictors of the hierarchies found in larger group settings, as they only predicted two of the four group hierarchies. Sex played no role in influencing status or behavior. Size had the greatest influence on dominance status, with larger fish being more dominant than smaller fish. An individual’s dominance ranking influenced both body coloration and posture. These results suggest that color patterns and body postures may also be used by observers as an indicator of an individual’s social status in groups [Current Zoology 56 (1: 18–35 2010].

    Although there exist advantages to group-living in comparison to a solitary lifestyle, costs and gains of group-living may be unequally distributed among group members. Predation risk, vigilance levels and food intake may be unevenly distributed across group spatial geometry and certain within-group spatial positions may be more or less advantageous depending on the spatial distribution of these factors. In species characterized with dominance hierarchy, high-ranking individuals are commonly observed in advantageous spatial position. However, in complex social systems, individuals can develop affiliative relationships that may balance the effect of dominance relationships in individual's spatial distribution. The objective of the present study is to investigate how the group spatial distribution of a semi-free ranging colony of Mandrills relates to its social organization. Using spatial observations in an area surrounding the feeding zone, we tested the three following hypothesis: (1) does dominance hierarchy explain being observed in proximity or far from a food patch? (2) Do affiliative associations also explain being observed in proximity or far from a food patch? (3) Do the differences in rank in the group hierarchy explain being co-observed in proximity of a food patch? Our results showed that high-ranking individuals were more observed in proximity of the feeding zone while low-ranking individuals were more observed at the boundaries of the observation area. Furthermore, we observed that affiliative relationships were also associated with individual spatial distributions and explain more of the total variance of the spatial distribution in comparison with dominance hierarchy. Finally, we found that individuals observed at a same moment in proximity of the feeding zone were more likely to be distant in the hierarchy while controlling for maternal kinship, age and sex similarity.

  16. Human infants' learning of social structures: the case of dominance hierarchy.

    We tested 15-month-olds' capacity to represent social-dominance hierarchies with more than two agents. Our results showed that infants found it harder to memorize dominance relations that were presented in an order that hindered the incremental formation of a single structure (Study 1). These results suggest that infants attempt to build structures incrementally, relation by relation, thereby simplifying the complex problem of recognizing a social structure. Infants also found circular dominance structures harder to process than linear dominance structures (Study 2). These expectations about the shape of structures may facilitate learning. Our results suggest that infants attempt to represent social structures composed of social relations. They indicate that human infants go beyond learning about individual social partners and their respective relations and form hypotheses about how social groups are organized.

  17. Political Elite under Manuel II Palaiologos: the Evolution of the Court Hierarchy

    Tatyana V. Kushch

    2016-11-01

    Full Text Available This paper will focus on the political elite of Byzantium in the late fourteenth and early fifteenth centuries and the changes in its structure. According to the analysis of prosopographic data, the number of the ruling elite considerably decreased during the reign of Manuel II Palaiologos. The hierarchy of titles and offices declined, so that many of them, even of supreme level, were not granted anymore, and later disappeared from political life. The central administrative machinery was reduced to the size of the imperial court. The ruling elite incorporated the descendants of famous Byzantine families and persons who established friendly relations with Manuel II. The emperor considerably raised the role of his intellectual retinue. Often without official titles and positions, the intellectuals, nevertheless, became key figures in the empire’s political affairs. However, in parallel to the ruling class that concentrated in the capital, Morea and Thessalonike developed their own local political elites. The hierarchy of officeholders doubled at the level of despotates, where positions from the former all-empire administration still existed. The developed system of administration of separate parts of the empire, the reduction of territories, limited financial resources, economic stagnation, and the decline of taxable population caused the degradation of the hierarchy of dignitaries, the simplification of the administrative system, and the change of the nature of mutual relations of the emperor and his courtiers.

    Dominance hierarchies play an important role in reducing competition and aggression in social animals. In zoos, changes in group composition are often required due to management protocols, but these changes may have long lasting effects on dominance hierarchies, and, consequently, the wellbeing of the animals. We studied the changes in the female dominance hierarchy that occurred both during and after the formation of a group of 10 adult Japanese macaques at the Zoo de Granby by combining members from two previously established groups. There was no significant correlation between individual ranks in the old groups (groups A and B) and their ranks in the new group (group AB), indicating a significant change in the hierarchy. Alliances between kin appeared to be important in determining rank; when the sister of the dominant female was removed from group AB, the hierarchy changed significantly a second time. The average standardized rank of individuals added later in the formation process of group AB was not different from those added earlier. Ranks in the group AB did correlate with age of individual at the beginning of the field season, but not at the end, after the shift in hierarchy occurred. Zoo management must be aware of the consequences small changes in a social group can have when removing and transferring individuals in both primates and in other social species.

    Full Text Available Since late 2000s, the political landscape in Bangladesh moved from democracy to an authoritarian kleptocracy, and experienced a new set of political and social narratives. This paper aims to contest some of these dominant/official narratives which have been discursively constructed and promoted by the secularist parties (including the ruling regime and groups in Bangladesh over recent years. Examining the sociopolitical and historical facts and figures of the country, we have identified five major contested narratives related to (a Bengali nationalism in East Pakistan, (b foundational ideology of Bangladesh’s war of liberation, (c state-sponsored Islamization in Bangladesh, (d pro-liberation and anti-liberation dichotomy, and (e war crimes trial. Drawing on a robust content analysis of the credible secondary sources substantiated by qualitative interviews, we have examined these dominant narratives and found that they are not supported by historical evidence and popular mandate, yet have been constructed largely to support and legitimize the current authoritarian regime. The paper offers both counter-narratives and some pragmatic policy recommendations to elude increasing polarization and sociopolitical instability and foster a peaceful democratic society in Bangladesh.

    Wild giraffes live in extensive groups in the fission fusion system, maintaining long social distances and loose social bonds. Within these groups, resources are widely distributed, agonistic encounters are scarce and the dominance hierarchy was reported in males only, while never deeply analysed. In captivity, the possibility to maintain inter-individual distances is limited and part of the resources is not evenly distributed. Consequently, we suggest that agonistic encounters should be more frequent, leading to the establishment of the dominance hierarchy. Based on the differences in resource-holding potential, we suggested that the rank of an individual would be affected by age and sex. Based on hypotheses of prior ownership, we tested whether rank was positively affected by the time spent in a herd and whether it was stable in adult females, which were present long-term in the same herd. We originally monitored four herds of Rothschild giraffes (Giraffa camelopardalis rothschildii) in Dvůr Králové zoo (n = 8), Liberec zoo (n = 6), and two herds in Prague zoo: Prague 1 (n = 8) and Prague 2 (n = 9). The Prague 1 and Prague 2 herds were then combined and the resulting fifth herd was observed over three consecutive years (2009, 2010, and 2011) (n = 14, 13, and 14, respectively). We revealed a significantly linear hierarchy in Dvůr Králové, Prague 2 and in the combined herd in Prague. Rank was significantly affected by age in all herds; older individuals dominated the younger ones. In females, rank was positively affected by the time spent in the herd and adult females in Prague maintained their rank during three consecutive years. This study represents the first analysis of the dominance hierarchy in the captive giraffe, and discusses the behavioural flexibility of the social structure in response to monopolisable resources in a captive environment.

    In this study, we conducted a series of experiments in a population of Vachellia constricta (Fabaceae) in the arid Tehuacan-Cuicatláan valley, Mexico, in order to evaluate if the food source quality and ant dominance hierarchy influence the outcomes of ant-plant interactions. Using an experiment with artificial nectaries, we observed that ants foraging on food sources with higher concentration of sugar are quicker in finding and attacking potential herbivorous insects. More specifically, we found that the same ant species may increase their defence effectiveness according to the quality of food available. These findings indicate that ant effectiveness in plant protection is context-dependent and may vary according to specific individual characteristics of plants. In addition, we showed that competitively superior ant species tend to dominate plants in periods with high nectar activity, emphasizing the role of the dominance hierarchy structuring ant-plant interactions. However, when high sugar food sources were experimentally available ad libitum, the nocturnal and competitively superior ant species, Camponotus atriceps, did not dominate the artificial nectaries during the day possibly due to limitation of its thermal tolerance. Therefore, temporal niche partitioning may be allowing the coexistence of two dominant ant species (Camponotus rubritorax during the day and C. atriceps at night) on V. constricta. Our findings indicate that the quality of the food source, and temporal shifts in ant dominance are key factors which structure the biotic plant defences in an arid environment.

    Political elections are dominance competitions. When men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels fall. However, it is unknown whether this pattern of testosterone change extends beyond interpersonal competitions to the vicarious experience of winning or losing in the context of political elections. Women's testosterone responses to dominance competition outcomes are understudied, and to date, a clear pattern of testosterone changes in response to winning and losing dominance competitions has not emerged. The present study investigated voters' testosterone responses to the outcome of the 2008 United States Presidential election. 183 participants provided multiple saliva samples before and after the winner was announced on Election Night. The results show that male Barack Obama voters (winners) had stable post-outcome testosterone levels, whereas testosterone levels dropped in male John McCain and Robert Barr voters (losers). There were no significant effects in female voters. The findings indicate that male voters exhibit biological responses to the realignment of a country's dominance hierarchy as if they participated in an interpersonal dominance contest.

    Full Text Available BACKGROUND: Political elections are dominance competitions. When men win a dominance competition, their testosterone levels rise or remain stable to resist a circadian decline; and when they lose, their testosterone levels fall. However, it is unknown whether this pattern of testosterone change extends beyond interpersonal competitions to the vicarious experience of winning or losing in the context of political elections. Women's testosterone responses to dominance competition outcomes are understudied, and to date, a clear pattern of testosterone changes in response to winning and losing dominance competitions has not emerged. METHODOLOGY/PRINCIPAL FINDINGS: The present study investigated voters' testosterone responses to the outcome of the 2008 United States Presidential election. 183 participants provided multiple saliva samples before and after the winner was announced on Election Night. The results show that male Barack Obama voters (winners had stable post-outcome testosterone levels, whereas testosterone levels dropped in male John McCain and Robert Barr voters (losers. There were no significant effects in female voters. CONCLUSIONS/SIGNIFICANCE: The findings indicate that male voters exhibit biological responses to the realignment of a country's dominance hierarchy as if they participated in an interpersonal dominance contest.

    While studies of sexual selection focus primarily on female choice and male-male competition, males should also exert mate choice in order to maximize their reproductive success. We examined male mate choice in mosquitofish, Gambusia holbrooki, with respect to female size and female dominance. We found that the number of mating attempts made by a male was predicted by the dominance rank of females in a group, with dominant females attracting more mating attempts than subordinates. The number of mating attempts made by males was independent of the female size. The observed bias in the number of mating attempts towards dominant females may be driven either by straightforward male mate choice, since dominance and female fecundity are often closely related, or via the dominant females mediating male mating behaviour by restricting their access to subordinate females.

  9. S-Lagrangian dynamics of many-body systems and behavior of social groups: Dominance and hierarchy formation

    Sandler, U.

    2017-11-01

    In this paper, we extend our generalized Lagrangian dynamics (i.e., S-Lagrangian dynamics, which can be applied equally to physical and non-physical systems as per Sandler (2014)) to many-body systems. Unlike common Lagrangian dynamics, this is not a trivial task. For many-body systems with S-dependent Lagrangians, the Lagrangian and the corresponding Hamiltonian or energy become vector functions, conjugated momenta become second-order tensors, and the system inevitably develops a hierarchical structure, even if all bodies initially have similar status and Lagrangians. As an application of our theory, we consider dominance and hierarchy formation, which is present in almost all communities of living species. As a biological basis for this application, we assume that the primary motivation of a groups activity is to attempt to cope with stress arising as pressure from the environment and from intrinsic unmet needs of individuals. It has been shown that the S-Lagrangian approach to a group's evolution naturally leads to formation of linear or despotic dominance hierarchies, depending on differences between individuals in coping with stress. That is, individuals that cope more readily with stress take leadership roles during the evolution. Experimental results in animal groups which support our assumption and findings are considered.

    Different types of dominance hierarchies reflect different social relationships in primates. In this study, we clarified the hierarchy and social relationships in a one-male unit of captive Rhinopithecus bieti observed between August 1998 and March 1999. Mean frequency of agonistic behaviour among adult females was 0.13 interactions per hour. Adult females exhibited a linear hierarchy with a reversal of 10.9%, indicating an unstable relationship; therefore, R. bieti appears to be a relaxed/tolerant species. The lack of a relationship between the agonistic ratio of the adult male towards adult females and their ranks indicated that males did not show increased aggression towards low-ranking females. Differentiated female affiliative relationships were loosely formed in terms of the male, and to some extent influenced by female estrus, implying that relationships between the male and females is influenced by estrus and not rank alone. A positive correlation between the agonistic ratio of adult females and their ranks showed that the degree to which one female negatively impacted others decreased with reduction in rank. Similarly, a positive correlation between the agonistic ratio of females and differences in rank suggests that a female had fewer negative effects on closely ranked individuals than distantly ranked ones. These data indicate that rank may influence relationships between females. A steeper slope of regression between the agonistic ratio and inter-female rank differences indicated that the extent of the power difference in high-ranking females exerting negative effects on low-ranking ones was larger during the mating season than the birth season, suggesting that rank may influence the mating success of females.

    Possible links between plasma testosterone levels, heavy metal loads and dominance in juvenile male willow tits (Parus montanus) are studied during winter conditions in Norway. Dominant individuals have better access to food resources, significantly higher cadmium content in the liver and higher plasma testosterone level compared to subordinates. A positive correlation was also found between plasma testosterone level and content of cadmium in the liver. Although the results in our study shows only a limited difference in testosterone level of dominant and subordinate juvenile male willow tits, possible small changes in behaviour might have crucial effects on winter survival of these birds. - Cadmium concentrations in juvenile male willow tits (Parus montanus) were correlated with plasma testosterone levels.

  15. Strong Migration Limit for Games in Structured Populations: Applications to Dominance Hierarchy and Set Structure

    2015-09-01

    Full Text Available In this paper, we deduce a condition for a strategy S1 to be more abundant on average at equilibrium under weak selection than another strategy S2 in a population structured into a finite number of colonies of fixed proportions as the population size tends to infinity. It is assumed that one individual reproduces at a time with some probability depending on the payoff received in pairwise interactions within colonies and between colonies and that the offspring replaces one individual chosen at random in the colony into which the offspring migrates. It is shown that an expected weighted average equilibrium frequency of S1 under weak symmetric strategy mutation between S1 and S2 is increased by weak selection if an expected weighted payoff of S1 near neutrality exceeds the corresponding expected weighted payoff of S2. The weights are given in terms of reproductive values of individuals in the different colonies in the neutral model. This condition for S1 to be favoured by weak selection is obtained from a strong migration limit of the genealogical process under neutrality for a sample of individuals, which is proven using a two-time scale argument. The condition is applied to games between individuals in colonies with linear or cyclic dominance and between individuals belonging to groups represented by subsets of a given set.

    Predation and competition are critical processes influencing the ecology of organisms, and can play an integral role in shaping coral reef fish communities. This study compared the relative and interacting effects of competition and predation on two competing species of coral reef fish, Pomacentrus amboinensis and P. moluccensis (Pomacentridae), using a multifactorial experiment. Fish were subjected to the sight and smell of a known predator (Pseudochromis fuscus), the presence of the heterospecific competitor (i.e., P. amboinensis vs. P. moluccensis), or a combination of the two for a period of 19 days. The sub-lethal effects of predator/competitor treatments were compared with controls; a combination of otolith microstructure analysis and observations were used to determine otolith growth patterns and behaviour. We predicted that the stress of competition and/or predation would result in strong sub-lethal impacts, and act synergistically on growth and behavioural patterns. We found strong evidence to support this prediction, but only for P. amboinensis, which suffered reductions in growth in both predator and competitor treatments, with the largest reductions occurring when subjected to both predation and competition concurrently. There was strong evidence of asymmetrical competition between the two damselfish species, with P. moluccensis as the dominant competitor, displaying strong aggressive behaviour towards P. amboinensis. Growth reductions for P. amboinensis in predator/competitor treatments appeared to come about primarily due to increases in shelter seeking behaviour, which significantly reduced the foraging rates of individuals compared with controls. These data highlight the importance of predator/competitor synergisms in influencing key behaviours and demographic parameters for juvenile coral reef fishes.

    Municipal solid waste is a central concern for environmental policy, and the sociomateriality of waste—the ways in which waste is socially defined and dealt with—is an important issue for sustainability. We show how applying the European Union’s waste policy through the European Waste Hierarchy (EWH) affects the sociomateriality of waste. The EWH ranks the desirability of different waste-management approaches according to their environmental impact. We investigate how the EWH has been acknowl...

  19. The Role of Grunt Calls in the Social Dominance Hierarchy of the White-Lipped Peccary (Mammalia, Tayassuidae.

    Full Text Available Grunt-like calls are present in the vocal repertoire of many group-living mammals and seem to facilitate social interactions between lower and higher-ranking members. The white-lipped peccary (Tayassu pecari lives in stable hierarchical mixed-sex groups and like non-human primates, usually emits grunt-like calls following aggressive interactions, mainly during feeding contexts. We investigated the possible functions of peccaries' grunt-like calls and their relationship to the individuals' social rank, identity, and sexual dimorphism. We observed that low-ranking individuals emitted grunt-like calls more often than high-ranking ones, and that the alpha male never emitted this vocalization. Moreover, the mean minimum frequency of grunt-like calls decreased as the peccary's rank increased. The findings revealed differences among individual grunts, but the low accuracy of cross-validation (16% suggests that individual recognition in peccaries may be less important than an honest signal of individual social status. In addition, the absence of differences in the acoustic parameters of grunt-like calls between males and females points to the lack of sexual dimorphism in this species. We verified that after hearing grunt calls, dominant opponents were more likely to cease attacking a victim, or at least delay the continuation of conflict, probably decreasing the severity of agonistic interactions. Our findings are particularly important to improve the current understanding of the role of grunt-like calls in herd-living mammals with linear dominant hierarchies, and strongly suggest that they are involved in the maintenance of herd social stability and cohesion.

    Group-living animals commonly display differences in behaviour, physiology and endocrine profiles between conspecifics within the group, which are tightly linked to reproduction. Teleosts exhibit a variety of social systems, where social status, as well as sex, has been linked to different androgen and oestrogen profiles. Levels of gonadal androgen and oestrogen were investigated as a function of sex and position in a social hierarchy in free-living individuals of the skunk anemonefish Amphiprion akallopisos, a protandrous pomacentrid fish with a size-based dominance hierarchical social system. Plasma levels of 11-ketotestosterone (11-KT), testosterone (T) and 17β-oestradiol (E 2 ), as well as conversion ratios from T, were measured by ELISA from 111 individuals along a linear hierarchy from 38 social groups in the wild. Blood plasma levels of 11-KT and E 2 showed sex differences, being higher in males and females respectively as expected based on their role as the major androgen and oestrogen in fish reproduction. However, no sex differences were found for T, which may represent its role in territorial defence or simply as a precursor for the synthesis of 11-KT and E 2 . In terms of the hierarchical social system within males, 11-KT levels decline as the hierarchy is descended, which may represent their decreasing reproductive opportunity, as well as the decreasing levels of aggression towards males lower in the hierarchy. In summary, the size-based dominance hierarchy is associated with distinct steroid levels of 11-KT and E 2 between individual free-living A. akallopisos that closely resemble those of species in which breeding individuals suppress reproduction of conspecifics lower in the hierarchy. © 2018 The Fisheries Society of the British Isles.

  3. Dominance hierarchies, diversity and species richness of vascular plants in an alpine meadow: contrasting short and medium term responses to simulated global change

    Full Text Available We studied the impact of simulated global change on a high alpine meadow plant community. Specifically, we examined whether short-term (5 years responses are good predictors for medium-term (7 years changes in the system by applying a factorial warming and nutrient manipulation to 20 plots in Latnjajaure, subarctic Sweden. Seven years of experimental warming and nutrient enhancement caused dramatic shifts in dominance hierarchies in response to the nutrient and the combined warming and nutrient enhancement treatments. Dominance hierarchies in the meadow moved from a community being dominated by cushion plants, deciduous, and evergreen shrubs to a community being dominated by grasses, sedges, and forbs. Short-term responses were shown to be inconsistent in their ability to predict medium-term responses for most functional groups, however, grasses showed a consistent and very substantial increase in response to nutrient addition over the seven years. The non-linear responses over time point out the importance of longer-term studies with repeated measurements to be able to better predict future changes. Forecasted changes to temperature and nutrient availability have implications for trophic interactions, and may ultimately influence the access to and palatability of the forage for grazers. Depending on what anthropogenic change will be most pronounced in the future (increase in nutrient deposits, warming, or a combination of them both, different shifts in community dominance hierarchies may occur. Generally, this study supports the productivity–diversity relationship found across arctic habitats, with community diversity peaking in mid-productivity systems and degrading as nutrient availability increases further. This is likely due the increasing competition in plant–plant interactions and the shifting dominance structure with grasses taking over the experimental plots, suggesting that global change could have high costs to biodiversity in the

    Full Text Available Overpopulation of African elephants (Loxodonta africana in fenced reserves in South Africa is becoming increasingly problematic to wildlife managers. With growing opposition to culling and the high cost of translocation, alternative management strategies focusing on male elephants are being investigated. In this study, hormonal treatment via Gonadotropin Releasing Hormone (GnRH suppression, and surgical treatment via vasectomy were trialled. Focusing on behavioural responses, we tested the male dominance hierarchy for transitivity, and examined the rank order of individuals in relation to age and contraceptive treatment received. Additionally, we studied association patterns between males within the male population and with the female herds.Findings suggest that the treatment of one individual with GnRH suppressant is affecting the rank order of the dominance hierarchy, though it is still transitive, yet fluid (Landau’s linearity index h=0.7, as expected in a normal elephant population. Between males, association patterns were found to be weak. However, some males had relatively strong associations with the female herds, with association indices between 0.25 and 0.41. This suggests that the reduction on births is resulting in the males spending atypically large amounts of time with the female herds. The future conservation implications of this population control mechanism are discussed.

    2015-12-01

    Full Text Available In a recent article, anthropologist Robert L. Carneiro reassessed his most debated hypothesis about the emergence of chiefdoms and the State as a result of environmental or social circumscription, theorized for a series of historical contexts including that of the Predynastic Nile Valley. The problem of the origin of the State is beyond our scope, but regarding the emergence of institutionalized leadership and chiefdoms in the Nile Valley, Carneiro’s ideas about warfare as a main factor in the process of social change remain interesting, even when his insistence in circumscription is still debatable. The aim of the present paper is to briefly review the available archaeological evidence of warfare among non-State societies of the Predynastic Nile Valley, and to evaluate its possible relation to the emergence of socio-political hierarchies, in turn refering to and criticizing some of Carneiro’s recent ideas about the issue.En un artículo reciente, Robert L. Carneiro presentó una reconsideración de su muy debatida hipótesis acerca de la emergencia de sociedades de jefatura y del Estado como resultado de un contexto de circunscripción ambiental, teorizada para una serie de situaciones históricas, entre ellas el valle del Nilo predinástico. El problema del origen del Estado excede las posibilidades de este trabajo, pero en lo que respecta al surgimiento de jefaturas, consideramos que las ideas de Carneiro acerca de la guerra como factor de importancia en el proceso revisten cierto interés, aun cuando su insistencia en la circunscripción continúa siendo discutible. El objetivo del presente artículo es considerar la evidencia arqueológica de guerra disponible para las sociedades no estatales del valle del Nilo predinástico y evaluar la posible relación entre dichos testimonios y la emergencia de jerarquías sociopolíticas, refiriendo y criticando algunas de las ideas recientes de Carneiro sobre el problema.

    Full Text Available The present research investigates the neurophysiological activity elicited by fast observations of faces of real candidates during simulated political elections. We used simultaneous recording of electroencephalographic (EEG signals as well as galvanic skin response (GSR and heart rate (HR as measurements of central and autonomic nervous systems. Twenty healthy subjects were asked to give judgments on dominance, trustworthiness, and a preference of vote related to the politicians’ faces. We used high-resolution EEG techniques to map statistical differences of power spectral density (PSD cortical activity onto a realistic head model as well as partial directed coherence (PDC and graph theory metrics to estimate the functional connectivity networks and investigate the role of cortical regions of interest (ROIs. Behavioral results revealed that judgment of dominance trait is the most predictive of the outcome of the simulated elections. Statistical comparisons related to PSD and PDC values highlighted an asymmetry in the activation of frontal cortical areas associated with the valence of the judged trait as well as to the probability to cast the vote. Overall, our results highlight the existence of cortical EEG features which are correlated with the prediction of vote and with the judgment of trustworthy and dominant faces.

  7. Non-domination and Political Institutions: The Contested Concept of Republican Democracy

    Directory of Open Access Journals (Sweden)

    Ricardo Silva

    2015-04-01

    Full Text Available Following the republican revival of the last few decades, the ideal of freedom as non-domination has become an important point of convergence among republican theorists, especially among those associated with neo-Roman republicanism. Furthermore, all neo-Roman theorists argue that a legitimate republican polity in contemporary societies must take a democratic form to overcome the aristocratic and elitist features pervasive in classical and modern republicanism. This study argues that the emerging concept of republican democracy remains essentially contested despite the increasing agreement on the ideal of liberty being constitutive of the republican tradition. It posits that the meaning of the concept of republican democracy becomes unstable in the transition from the normative ideal to the institutional level of neo-republican reasoning, which is evidenced by the fact that neo-Roman theorists embrace the ideal of non-domination but disagree on the characteristics of the institutional design capable of realizing that ideal. To substantiate this argument, the study compares three recent models of democracy that are somehow associated with neo-Roman republicanism—the electoral-contestatory model, the political constitutionalism model, and the Machiavellian democracy model, championed by Philip Pettit, Richard Bellamy, and John McCormick, respectively.

    In group-living animals, individuals do not interact uniformly with their conspecifics. Among primates, such heterogeneity in partner choice can be discerned from affiliative grooming patterns. While the preference for selecting close kin as grooming partners is ubiquitous across the primate order, the selection of higher-ranking non-kin individuals as grooming partners is less common. We studied a group of provisioned rhesus macaques (Macaca mulatta brevicaudus) on Hainan Island, China, to examine rank-related benefits of grooming exchanges and the influence of kin relationships. We tested four hypotheses based on Seyfarth's model: (1) there will be kin preference in grooming relationships; (2) grooming between non-kin individuals will be directed up the dominance rank; (3) grooming between non-kin individuals will reduce aggression from higher-ranking ones; and (4) non-kin individuals will spend more time grooming with adjacent ranked ones. We found that grooming relationships between kin individuals were stronger than those between non-kin individuals. For non-kin relationships, lower-ranking individuals received less aggression from higher-ranking ones through grooming; a benefit they could not derive through grooming exchanges with individuals related by kinship. Individuals spent more time grooming adjacent higher-ranking non-kin individuals and higher-ranking individuals also received more grooming from non-kin individuals. Our results supported Seyfarth's model for predicting partner choice between non-kin individuals. For relationships between kin individuals, we found results that were not consistent with prediction for the exchanges of aggression and grooming, indicating the importance to control for the influence of kinship in future studies.

  9. Politeness

    Henri Bergson

    2016-12-01

    Full Text Available This is the English translation of a speech Bergson made at Lycée Henri-IV on July 30, 1892. This is an interesting text because it anticipates Bergson’s last book, his The Two Sources of Morality and Religion. Like the distinction in The Two Sources between the open and the closed, “Politeness” defines its subject matter in two ways. There is what Bergson calls “manners” and there is true politeness. For Bergson, both kinds of politeness concern equality. Manners or material politeness amount to the ritualized greetings and formalities by means of which we usually define politeness. Unfortunately and like The Two Sources, Bergson attributes this formalized relation to other human beings with primitive and “inferior races.” Nevertheless, Bergson sees in these formalities an attempt, in the name of equality, to ignore other people’s talents and merits so that one can dominate morally superior people. In contrast, true politeness or “spiritual politeness” consists in “intellectual flexibility.” When one meets a person of superior morality, one is flexible in one’s relation to him or her; one abandons the formalities in order to really live her life and think her thoughts. Here we find equality too: “what defines this very polite person is to prefer each of his friends over the others, and to succeed in this way in loving them equally.” After making a comparison to dance, Bergson defines spiritual politeness as “a grace of the mind.” Since both kinds of politeness concern equality, Bergson associates both with justice. However, beyond these two kinds of politeness and justice there is “politeness of the heart,” which concerns charity. In order to indicate politeness of the heart, Bergson describes the kind of person, a sensitive person, who anxiously awaits a word of praise in order to feel good about herself but who also, when she hears a word of reproach, is thrown into sadness. Although Bergson calls the

  10. Rethinking State Politics: The Withering of State Dominant Machines in Brazil

    2007-03-01

    Full Text Available Research on Brazilian federalism and state politics has focused mainly on the impact of federal arrangements on national political systems, whereas comparative analyses of the workings of state political institutions and patterns of political competition and decision-making have often been neglected. The article contributes to an emerging comparative literature on state politics by developing a typology that systematizes the variation in political competitiveness and the extent of state elites’ control over the electoral arena across Brazilian states. It relies on factor analysis to create an index of “electoral dominance”, comprised of a set of indicators of party and electoral competitiveness at the state level, which measures state elites’ capacity to control the state electoral arena over time. Based on this composite index and on available case-study evidence, the article applies the typological classificatory scheme to all 27 Brazilian states. Further, the article relies on the typological classification to assess the recent evolution of state-level political competitiveness. The empirical analysis demonstrates that state politics is becoming more competitive and fragmented, including in those states that have been characterized as bastions of oligarchism and political bossism. In view of these findings, the article argues that the power of state political machines rests on fragile foundations: in Brazil’s multiparty federalism, vertical competition between the federal and state governments in the provision of social policies works as a constraint on state bosses’ machine-building strategies. It is concluded that our previous views on state political dynamics are in serious need of re-evaluation.

    India has an eclectic health system that incorporates biomedical as well as traditional, complementary and alternative medicine (TCAM). Our understanding of the co-existence of these therapeutic modalities in this diverse, postcolonial and developing nation is extremely limited, and in the context of cancer care, to our knowledge no sociological work has been carried out. Contemporary Indian oncology represents a fascinating site for examining the interplay and articulation of forms of tradition/modernity, economic progress/structural constraint and individual beliefs/cultural norms. In a context of an increase in the prevalence and impact of cancer in an ageing Indian population, this paper reports on a qualitative investigation of a group of oncology clinicians' accounts of 'pluralism' in India. The results illustrate the embeddedness of patient disease and therapeutic trajectories in vast social inequalities and, indeed, the intermingling of therapeutic pluralism and the politics of social value. We conclude that notions of pluralism, so often espoused by global health organisations, may conceal important forms of social inequality and cultural divides, and that sociologists should play a critical role in highlighting these issues.

    2017-01-01

    Written by a former Aerodynamics Officer on the space shuttle program, this book provides a complete overview of the “new” U. S. space program, which has changed considerably over the past 50 years.The future of space exploration has become increasingly dependent on other countries and private enterprise. Can private enterprise can fill the shoes of NASA and provide the same expertise and safety measures and lessons learned from NASA? In order to tell this story, it is important to understand the politics of space as well as the dangers, why it is so difficult to explore and utilize the resources of space. Some past and recent triumphs and failures will be discussed, pointing the way to a successful space policy that includes taking risks but also learning how to mitigate them.

  15. Rural health efforts in the urban-dominated political economy: three Third World examples.

    The theme of this paper is to demonstrate that the urban preference in governmental health delivery programs does exists in capitalist and socialist political economies and that efficient rural health programs exist in capitalist and socialist developing countries. The purpose of the article is to determine strategies to promote accessible rural health care by studying 3 examples. In the State of Kerala, India between 1956-1959, land reforms were carried out, and political parties and agrarian cooperatives involving rural people were organized. rural needs were given top priority in this capitalist economy which resulted in agrarian reform, education, and health delivery. In 1971, food production increased to 5.4 million tons. During this period, the nutritional status rose, the mortality rated declined, and the fertility rates decreased. Thus, the health status for the rural population improved. Bolivia's Montero health program was developed in 1975. This case demonstrates the urban/rural conflict in a capitalist economy with preference given to the urban side. This proposed health program resulted in the urban communities receiving greater resources compared to the rural population. This result is attributed to lack of organization within the rural population. The final case examined was Nicaragua which in 1979 was socialist. The National Unified Health System was established by the Sandinistas and had 4 priorities: revolution defense, economy, education, and health. This movement by the Sandinistas addressed rural health problems and challenged the urban medical organization. Health care workers were trained to deliver more curative and preventative services. The Popular Health Councils in Nicaragua is unique; it provides discussion regarding the urban/rural conflict. A change in the Minister of Health also indicated concern for rural health care delivery. Nicaragua's health status also improved as a result of rural organization. From the 3 cases, it was

    There is an increasing need to couple environmental and economic considerations within waste management. Consumers and companies alike generate ever more waste. The waste-policy challenges of the future lie in decoupling growth in waste generation from growth in consumption, and in setting priorities for the waste management. This report discusses the criteria for deciding priorities for waste management methods, and questions the current principles of EU waste policies. The basis for the discussion is the so-called waste hierarchy which has dominated the waste policy in the EU since the mid-1970s. The waste hierarchy ranks possible methods of waste management. According to the waste hierarchy, the very best solution is to reduce the amount of waste. After that, reuse is preferred to recycling which, in turn, is preferred to incineration. Disposal at a landfill is the least favourable solution. (BA)

    In contrast to authors of previous single-nation studies, we propose that supporting multiculturalism (MC) or assimilation (AS) is likely to have different effects in different countries, depending on the diversity policy in place in a particular country and the associated norms. A causal model of intergroup attitudes and behaviors, integrating both country-specific factors (attitudes and perceived norms related to a particular diversity policy) and general social-psychological determinants (social dominance orientation), was tested among participants from countries where the pro-diversity policy was independently classified as low, medium, or high (N = 1,232). Results showed that (a) anti-Muslim prejudice was significantly reduced when the pro-diversity policy was high; (b) countries differed strongly in perceived norms related to MC and AS, in ways consistent with the actual diversity policy in each country and regardless of participants' personal attitudes toward MC and AS; (c) as predicted, when these norms were salient, due to subtle priming, structural equation modeling with country included as a variable provided support for the proposed model, suggesting that the effect of country on prejudice can be successfully accounted by it; and (d) consistent with the claim that personal support for MC and AS played a different role in different countries, within-country mediation analyses provided evidence that personal attitudes toward AS mediated the effect of social dominance orientation on prejudice when pro-diversity policy was low, whereas personal attitudes toward MC was the mediator when pro-diversity policy was high. Thus, the critical variables shaping prejudice can vary across nations. PsycINFO Database Record (c) 2013 APA, all rights reserved.

Di bawah teraju pemimpin bumiputera Islam ini, Barisan Nasional berjaya menguasai setiap pilihan raya negeri dan parlimen yang diadakan sejak tahun 1970 hingga 2008. Walaupun parti pembangkang melancarkan tentangan sengit pada lewat 1970-an dan pertengahan 1980-an, pemimpin bumiputera Islam ini berjaya mengatasinya untuk terus mengekalkan dominasi parti pemerintah di negeri yang mempunyai bilangan kerusi negeri dan parlimen yang terbanyak. Makalah ini menyusuri dominasi politik pemimpin bumiputera Islam Sarawak dan faktor-faktor yang menyumbang kepada kekuatan mereka yang menjangkau lebih empat dekad. Walaupun kuasa politik pemimpin bumiputera Islam masih bertahan sehingga ke hari ini, beberapa sumber baharu mulai muncul untuk memberikan tentangan terhadap kuasa politik golongan minoriti ini. Sumber tentangan baharu yang dimaksudkan ialah golongan kelas menengah, United Malays National Organisation (UMNO dan inteligensia. Makalah ini mengupas tentangan yang diberikan kelompok ini dan impaknya terhadap politik Sarawak khususnya kepimpinan bumiputera Islam.The ruling Barisan Nasional started to dominate Sarawak politics after the Muslim bumiputera took over the state leadership from the Iban after the 1970 elections.

    Full Text Available Employing a dual process motivational (DPM model perspective, we found that how political messages are framed influences the differential effects of right-wing authoritarianism (RWA and social dominance orientation (SDO on political candidate support in the United States. Study 1 (N = 85 found that RWA and SDO differentially predicted support for right-wing candidates who used cohesion and group status threats to frame same-sex marriage, respectively. Study 2 (N = 89 largely replicated those findings on immigration policy. In Study 3 (N = 128, the hypothesis that RWA and SDO negatively predicted support for left-wing candidates who framed same-sex marriage in terms of individual liberty and social equality, respectively, received partial support. Additional analyses indicated that the effects of RWA on candidate support in these studies were driven by specific theoretically-relevant dimensions of RWA. Together, these results indicate that candidates can enhance their appeal by strategically employing value-based political messages targeting different subsets of their constituency.

  2. Models of Neutrino Masses: Anarchy versus Hierarchy

    2003-01-01

    We present a quantitative study of the ability of models with different levels of hierarchy to reproduce the solar neutrino solutions, in particular the LA solution. As a flexible testing ground we consider models based on SU(5) × U(1)F. In this context, we have made statistical simulations of models with different patterns from anarchy to various types of hierarchy: normal hierarchical models with and without automatic suppression of the 23 (sub)determinant and inverse hierarchy models. We find that, not only for the LOW or VO solutions, but even in the LA case, the hierarchical models have a significantly better success rate than those based on anarchy. The normal hierarchy and the inverse hierarchy models have comparable performances in models with see-saw dominance, while the inverse hierarchy models are particularly good in the no see-saw versions. As a possible distinction between these categories of models, the inverse hierarchy models favour a maximal solar mixing angle and their rate of success drops dramatically as the mixing angle decreases, while normal hierarchy models are far more stable in this respect.

  3. Hierarchy and social status in Budongo chimpanzees.

    Newton-Fisher, Nicholas E

    2004-04-01

    The status hierarchy is fundamental in the lives of male chimpanzees. This study describes the dominance interactions and social status among adult male chimpanzees of the Sonso community in the Budongo Forest Reserve, Uganda, during the period that they were first studied (1994 and 1995). Social dominance is typically measured using the behaviour of either the subordinate or the dominant individual, but a relationship is dependent on the behaviour of both parties and this study explicitly used both subordinate and dominant behaviours to investigate the status hierarchy. Among adult males of the Sonso community, agonistic interactions occurred at a low rate and pant-grunts were rare, but males could be ranked into separate hierarchies of agonistic dominance and pant-grunting (labelled 'respect') using ratios of behaviour performed/behaviour received. These hierarchies were combined to form a single hierarchy of social status that divided the males among five distinct status levels. The highest status level was held by an alliance between two males who replaced the previous alpha male during the first part of the study. Neither male in this alliance partnership pant-grunted to the other, although the reason for cooperative behaviour was unclear. Although the nominally beta male was treated as such by other adult males, he achieved surprisingly little mating success. Budongo Forest chimpanzees do not warrant the sometimes-expressed view that they are non-aggressive and peaceable and the broad pattern of their status interactions matches with that seen in other chimpanzee populations.

  7. Why hierarchies thrive.

    Leavitt, Harold J

    2003-03-01

    Hardly anyone has a good word to say about hierarchies. Academics, consultants, and management gurus regularly forecast their imminent replacement because hierarchies--even when populated by considerate and intelligent people--can be cruel and stupid. They routinely transform motivated and loyal employees into disaffected Dilberts. It's no wonder that we continue to search for more humane and productive alternatives to them. Yet the intensity with which we struggle against hierarchies only serves to highlight their durability. Hierarchy, it seems, may be intrinsic not only to the natural world but also to our own natures. In this article, organizational behavior expert Harold J. Leavitt presents neither a defense of human hierarchies nor another attack on them. Instead, he offers a reality check, a reminder that hierarchy remains the basic structure of most, if not all, large, ongoing human organizations. That's because although they are often depicted as being out of date, hierarchies have proved to be extraordinarily adaptive. Over the past 50 years, for example, they have co-opted the three major managerial movements--human relations, analytic management, and communities of practice. Hierarchies also persist because they deliver real practical and psychological value, and they fulfill our deep need for order and security. Despite the good they may do, hierarchies are inevitably authoritarian. That authoritarianism shows up in all kinds of ways and influences everything in organizations, particularly communication. In multilevel organizations, for instance, messages get distorted as they travel up and down the ladder of command. Self-protection and self-interest weigh in, and relevant information is lost as messages make stops along the route. Sensitive leaders take steps to make speaking the truth as painless as possible. But it never is in organizations, because authoritarianism is an immutable element of hierarchy.

  8. Context-dependent hierarchies in pigeons.

    Hierarchical organization is widespread in the societies of humans and other animals, both in social structure and in decision-making contexts. In the case of collective motion, the majority of case studies report that dominant individuals lead group movements, in agreement with the common conflation of the terms "dominance" and "leadership." From a theoretical perspective, if social relationships influence interactions during collective motion, then social structure could also affect leadership in large, swarm-like groups, such as fish shoals and bird flocks. Here we use computer-vision-based methods and miniature GPS tracking to study, respectively, social dominance and in-flight leader-follower relations in pigeons. In both types of behavior we find hierarchically structured networks of directed interactions. However, instead of being conflated, dominance and leadership hierarchies are completely independent of each other. Although dominance is an important aspect of variation among pigeons, correlated with aggression and access to food, our results imply that the stable leadership hierarchies in the air must be based on a different set of individual competences. In addition to confirming the existence of independent and context-specific hierarchies in pigeons, we succeed in setting out a robust, scalable method for the automated analysis of dominance relationships, and thus of social structure, applicable to many species. Our results, as well as our methods, will help to incorporate the broader context of animal social organization into the study of collective behavior.

  9. Stress amplifies memory for social hierarchy

    Directory of Open Access Journals (Sweden)

    María I Cordero

    2007-10-01

    Full Text Available Individuals differ in their social status and societies in the extent of social status differences among their members. There is great interest in understanding the key factors that contribute to the establishment of social dominance structures. Given that stress can affect behavior and cognition, we hypothesized that, given equal opportunities to become either dominant or submissive, stress experienced by one of the individuals during their first encounter would determine the long-term establishment of a social hierarchy by acting as a two-stage rocket: (1 by influencing the rank achieved after a social encounter and (2 by facilitating and/or promoting a long-term memory for the specific hierarchy. Using a novel model for the assessment of long-term dominance hierarchies in rats, we present here the first evidence supporting such hypothesis. In control conditions, the social rank established through a first interaction and food competition test between two male rats is not maintained when animals are confronted 1 week later. However, if one of the rats is stressed just before their first encounter, the dominance hierarchy developed on day 1 is still clearly observed 1 week later, with the stressed animal becoming submissive (i.e., looser in competition tests in both social interactions. Our findings also allow us to propose that stress potentiates a hierarchy-linked recognition memory between “specific” individuals through mechanisms that involve de novo protein synthesis. These results implicate stress among the key mechanisms contributing to create social imbalance and highlight memory mechanisms as key mediators of stress-induced long-term establishment of social rank.

    We discuss a supersymmetric preon model which predicts three families of quarks and leptons. An acceptable mass hierarchy among the three fermion generations arises from a combination of mass protection mechanism due to supersymmetry and chiral symmetry on the one hand, and a hierarchy in the sizes of the composites on the other hand. A metacolor force with a scale Λsub(MC) >> 1 TeV binds the e- and the μ-families while a hypercolor force with a scale Λsub(HC) proportional 1 TeV binds the tau-bamily; it also breaks chiral symmetry dynamically.

    2013-12-01

    Full Text Available Social dominance theory was developed to account for why societies producing surplus take and maintain the form of group-based dominance hierarchies, in which at least one socially-constructed group has more power than another, and in which men are more powerful than women and adults more powerful than children. Although the theory has always allowed for societies to differ in their severity of group-based dominance and how it is implemented, it has predicted that alternative forms of societal organization will occur rarely and not last. This paper revisits aspects of the theory that allow for the possibility of societal alternatives and change. We also consider boundary conditions for the theory, and whether its current theoretical apparatus can account for societal change. By expanding the typical three-level dynamic system to describe societies (micro-meso-macro into four levels (including meta to consider how societies relate to one another, we identify political tensions that are unstable power structures rather than stable hierarchies. In research on institutions, we identify smaller-scale alternative forms of social organization. We identify logical, empirical, and theoretical shortcomings in social dominance theory’s account of stability and change, consider alternative forms of social organization, and suggest fruitful avenues for theoretical extension.

  14. Toda hierarchies and their applications

    2018-05-01

    The 2D Toda hierarchy occupies a central position in the family of integrable hierarchies of the Toda type. The 1D Toda hierarchy and the Ablowitz–Ladik (aka relativistic Toda) hierarchy can be derived from the 2D Toda hierarchy as reductions. These integrable hierarchies have been applied to various problems of mathematics and mathematical physics since 1990s. A recent example is a series of studies on models of statistical mechanics called the melting crystal model. This research has revealed that the aforementioned two reductions of the 2D Toda hierarchy underlie two different melting crystal models. Technical clues are a fermionic realization of the quantum torus algebra, special algebraic relations therein called shift symmetries, and a matrix factorization problem. The two melting crystal models thus exhibit remarkable similarity with the Hermitian and unitary matrix models for which the two reductions of the 2D Toda hierarchy play the role of fundamental integrable structures.

    We consider a general framework for integrable hierarchies in Lax form and derive certain universal equations from which 'functional representations' of particular hierarchies (such as KP, discrete KP, mKP, AKNS), i.e. formulations in terms of functional equations, are systematically and quite easily obtained. The formalism genuinely applies to hierarchies where the dependent variables live in a noncommutative (typically matrix) algebra. The obtained functional representations can be understood as 'noncommutative' analogues of 'Fay identities' for the KP hierarchy

    are complex and not easily fit into tidy boxes of absolute truth, as are commonly given preference in science, technology and medicine fields.I believe the focus on quantitative research arose within EBLIP for two reasons: 1 EBL formed within medical librarianship and those librarians identified more closely with the medical model of problem solving, which placed a higher level of trust in quantitative research; and, 2 there was a tide-swell of professional librarians who were tired of seeing our literature dominated by stories of ‚how I did it good‛, and wanted to see more research being published rather than opinion. This led to sometimes strongly worded and simplistic rhetoric noting that some forms of publication were not scientific, in order perhaps to highlight the importance of quality research. Unfortunately, qualitative research was caught up in this wave and projected as not as worthy as quantitative research. This is clearly noted in the levels of evidence hierarchies that became part of the EBLIP doctrine.In both his original published article on the levels of evidence within EBL (2000a, and a subsequent version (2002, Eldredge places qualitative forms of evidence at or near the bottom of the spectrum, although elsewhere he has recognized the role of both quantitative and qualitative research (2000b. The 2002 version of Eldredge’s levels of evidence does put ‚qualitative research‛ at the middle of the continuum for exploration-type questions, but it still seems marginalized, summed up by a single line as if all qualitative research is one; whereas in the other categories, quantitative methods are given granular description. This model has been readily accepted, but there remains a lack of research on why this would work for librarianship. My concern is that the hierarchical structure may have been too easily accepted and taken as truth, marginalizing other forms of research and not referring back to the original research question. It also could

    Full Text Available Most economists expected that the “Great Recession” produced by the financial meltdown of 2008 would usher in a resurgence of traditional Keynesian economics and a decline of what has come to be called “market fundamentalism”. By contrast, also due to the inadequate size of the 2009 stimulus package, the resurgence of support for Keynesian expenditure policies has been extremely short lived. However, the negative popular and political reaction should not have come as a surprise, at least for three reasons: the design of the Obama stimulus plan and its difference from the expenditure policies of the Roosevelt Administration; the political environment that has eviscerated fiscal policy and placed monetary policy at the centre of economic policy and produced “debt driven” growth; the difference between policies appropriate to treating an income deflation and a debt deflation.   JEL: G01, B50, N12, H12

    Dominance hierarchies occur in numerous social species, and rank within them can greatly influence the quality of life of an animal. In this review, I consider how rank can also influence physiology and health. I first consider whether it is high- or low-ranking animals that are most stressed in a dominance hierarchy; this turns out to vary as a function of the social organization in different species and populations. I then review how the stressful characteristics of social rank have adverse adrenocortical, cardiovascular, reproductive, immunological, and neurobiological consequences. Finally, I consider how these findings apply to the human realm of health, disease, and socioeconomic status.

  1. From Pericles to Plato – from democratic political praxis to totalitarian political philosophy

    Directory of Open Access Journals (Sweden)

    2012-03-01

    Full Text Available Plato is normally taken as one of the founders of Western political philosophy, not at least with his Republic. Here, he constructs a hierarchy of forms of governments, beginning with aristocracy at the top as a critical standard for the other forms of governments, and proceeding through timocracy and oligarchy to democracy and tyranny at the bottom. Following Karl Popper, the paper argues that Plato’s is a totalitarian philosophy that emphasizes the similarities between democracy and tyranny, which it considers to be the two worst forms of government. Plato’s denigration of democracy has dominated the tradition of political philosophy until recent times. This paper, however, shows that political philosophy in fact originates in democracy, especially as developed by the sophists and that philosophy is only a form of sophism with a similar origin in ancient Greek democracy. A discussion of Pericles’ funeral oration is used to show that Pericles presented a democratic political philosophy that can serve as a counterpoint to Plato’s political philosophy in the Republic.

  2. The Fragility of Individual-Based Explanations of Social Hierarchies: A Test Using Animal Pecking Orders.

    Directory of Open Access Journals (Sweden)

    Ivan D Chase

    Full Text Available The standard approach in accounting for hierarchical differentiation in biology and the social sciences considers a hierarchy as a static distribution of individuals possessing differing amounts of some valued commodity, assumes that the hierarchy is generated by micro-level processes involving individuals, and attempts to reverse engineer the processes that produced the hierarchy. However, sufficient experimental and analytical results are available to evaluate this standard approach in the case of animal dominance hierarchies (pecking orders. Our evaluation using evidence from hierarchy formation in small groups of both hens and cichlid fish reveals significant deficiencies in the three tenets of the standard approach in accounting for the organization of dominance hierarchies. In consequence, we suggest that a new approach is needed to explain the organization of pecking orders and, very possibly, by implication, for other kinds of social hierarchies. We develop an example of such an approach that considers dominance hierarchies to be dynamic networks, uses dynamic sequences of interaction (dynamic network motifs to explain the organization of dominance hierarchies, and derives these dynamic sequences directly from observation of hierarchy formation. We test this dynamical explanation using computer simulation and find a good fit with actual dynamics of hierarchy formation in small groups of hens. We hypothesize that the same dynamic sequences are used in small groups of many other animal species forming pecking orders, and we discuss the data required to evaluate our hypothesis. Finally, we briefly consider how our dynamic approach may be generalized to other kinds of social hierarchies using the example of the distribution of empty gastropod (snail shells occupied in populations of hermit crabs.

    Whether and how societal structures shape individual psychology is a foundational question of the social sciences. Combining insights from evolutionary biology, economy, and the political and psychological sciences, we identify a central psychological process that functions to sustain group-based hierarchies in human societies. In study 1, we demonstrate that macrolevel structural inequality, impaired population outcomes, socio-political instability, and the risk of violence are reflected in the endorsement of group hegemony at the aggregate population level across 27 countries (n = 41,824): The greater the national inequality, the greater is the endorsement of between-group hierarchy within the population. Using multilevel analyses in study 2, we demonstrate that these psychological group-dominance motives mediate the effects of macrolevel functioning on individual-level attitudes and behaviors. Specifically, across 30 US states (n = 4,613), macrolevel inequality and violence were associated with greater individual-level support of group hegemony. Crucially, this individual-level support, rather than cultural-societal norms, was in turn uniquely associated with greater racism, sexism, welfare opposition, and even willingness to enforce group hegemony violently by participating in ethnic persecution of subordinate out-groups. These findings suggest that societal inequality is reflected in people’s minds as dominance motives that underpin ideologies and actions that ultimately sustain group-based hierarchy. PMID:28484013

    We advocate a new approach to study models of fermion massesand mixings, namely anarchy proposed in hep-ph/9911341. In this approach,we scan the O(1) coefficients randomly. We argue that this is the correctapproach when the fundamental theory is sufficiently complicated.Assuming there is no physical distinction among three generations ofneutrinos, the probability distributions in MNS mixing angles can bepredicted independent of the choice of the measure. This is because themixing angles are distributed according to the Haar measure of the Liegroups whose elements diagonalize the mass matrices. The near-maximalmixings, as observed in the atmospheric neutrino data and as required inthe LMA solution to the solar neutrino problem, are highly probable. Asmall hierarchy between the Delta m2 for the atmospheric and the solarneutrinos is obtained very easily; the complex seesaw case gives ahierarchy of a factor of 20 as the most probable one, even though thisconclusion is more measure-dependent. U_e3 has to be just below thecurrent limit from the CHOOZ experiment. The CP-violating parameter sindelta is preferred to be maximal. We present a simple SU(5)-likeextension of anarchy to the charged-lepton and quark sectors which workswell phenomenologically.

    This paper summarizes some of the problems associated with the generation of higher order emergent structures in formal dynamical systems. In biological systems, higher order hyperstructures occur both in an intuitive and a formal sense: monomers, polymers, membranes, organelles, cells, tissues, organs, etc. constitute an observable hierarchy, apparently generated by the underlying biomolecular process. However, in models and simulations of these systems, it has turned out to be quite difficult to produce higher order emergent structures from first principles. The first problem is to agree on what a higher order structure is. An emergent structure can be defined through an introduction of an observational function. If a property can be observed in the dynamics, but not at the level of the fundamental first order interacting structures, we define it to be emergent. It is well known that second order structures occur relatively easy in simulation, so the problem is how to proceed to third and higher order without external interference. A third order structure is defined through the interaction of second order structures forming a new observable not found at the lower levels.

    2017-02-01

    One driving motivation of systems biology is the search for general principles that govern the design of biological systems. But questions often arise as to what kind of general principles biology could have. Concepts from engineering such as robustness and modularity are indeed becoming a regular way of describing biological systems. Another source of potential general principles is the emerging similarities found in processes across biological hierarchies. In this piece, I describe several emerging cross-hierarchy similarities. Identification of more cross-hierarchy principles, and understanding the implications these convergence have on the construction of biological systems, I believe, present exciting challenges for systems biology in the decades to come.

  11. Gauge-symmetry hierarchies revisited

    International Nuclear Information System (INIS)

    Gildener, E.

    1979-01-01

    It was shown by the author in a previous paper that in each order of perturbation theory there is an upper bound on the range of validity of a gauge hierarchy. Thus constructing a large hierarchy requires a fine-tuning of the scalar-field parameters. It was stated that the possibility of an inherent bound on the hierarchy exists, but the question of the actual existence of such a bound was left completely open. Since then several authors have addressed this problem. Some of what the author asserted was misunderstood, and incorrect conclusions have been drawn from recent computations. It has been claimed that the existence of large hierarchies has been demonstrated. It is the purpose of this paper to refute this claim, to help clarify the situation, and to explain why the status of this problem has in fact not really changed in recent years (author)

    We consider models of growing multilevel systems wherein the growth process is driven by rules of tournament selection. A system can be conceived as an evolving tree with a new node being attached to a contestant node at the best hierarchy level (a level nearest to the tree root). The proposed evolution reflects limited information on system properties available to new nodes. It can also be expressed in terms of population dynamics. Two models are considered: a constant tournament (CT) model wherein the number of tournament participants is constant throughout system evolution, and a proportional tournament (PT) model where this number increases proportionally to the growing size of the system itself. The results of analytical calculations based on a rate equation fit well to numerical simulations for both models. In the CT model all hierarchy levels emerge, but the birth time of a consecutive hierarchy level increases exponentially or faster for each new level. The number of nodes at the first hierarchy level grows logarithmically in time, while the size of the last, "worst" hierarchy level oscillates quasi-log-periodically. In the PT model, the occupations of the first two hierarchy levels increase linearly, but worse hierarchy levels either do not emerge at all or appear only by chance in the early stage of system evolution to further stop growing at all. The results allow us to conclude that information available to each new node in tournament dynamics restrains the emergence of new hierarchy levels and that it is the absolute amount of information, not relative, which governs such behavior.

    At its substratum, brain/mind organization requires both synaptic firings and non-synaptic events. Synaptic firings organize the pattern of non-synaptic events. Non-synaptic events organize the pattern of synaptic firings. The processes are related in a bizarre hierarchy. Comparing these processes to electric circuits, it is as if we have two circuits that each continuously and simultaneously update the topology, and consequently, the dynamical laws of the other. Since either can be seen to be rebuilding the other, from its own perspective each process appears higher than the other in a hierarchy. This same kind of hierarchy is found in a hyperset structure. Interpreted as a directed graph, the nodes in a hyperset form a hierarchy in which, from the perspective of any node in the hierarchy, that node is at the top. This organizational structure violates the Foundation Axiom. Algorithmic computation strictly complies with the Foundation Axiom. Thus, an algorithm organized like a hyperset is a contradiction in terms. Does this contradiction mean are we precluded forever from implementing brain-like activities artificially? Not at all! An algorithm is incapable of doing the job, but nothing prevents us from constructing interacting analog processes that update each other's dynamical laws on the fly.

    Full Text Available Visual hierarchy is a significant concept in the field of advertising, a field that is dominated by effective communication, visual recognition and motion. Designers of advertisements have always been trying to organize the visual hierarchy throughout their advertising designs to aid the eye to recognize information in the desired order, to achieve the ultimate goals of clear perception and effectively delivering the advertising messages. However many assumptions and questions usually rise on how to create effective hierarchy throughout advertising designs and lead the eye and mind of the viewer in the most favorable way. This paper attempts to study visual hierarchy and mind motion in advertising designs and why it is important to develop visual paths when designing an advertisement. It explores the theory behind it, and how the very principles can be used to put these concepts into practice. The paper demonstrates some advertising samples applying visual hierarchy and mind motion in a representation of applying the basics and discussing the results.

    The Poisson geometry of a discrete string in three dimensional Euclidean space is investigated. For this the Frenet frames are converted into a spinorial representation, the discrete spinor Frenet equation is interpreted in terms of a transfer matrix formalism, and Poisson brackets are introduced in terms of the spinor components. The construction is then generalised, in a self-similar manner, into an infinite hierarchy of Poisson algebras. As an example, the classical Virasoro (Witt) algebra that determines reparametrisation diffeomorphism along a continuous string, is identified as a particular sub-algebra, in the hierarchy of the discrete string Poisson algebra. - Highlights: • Witt (classical Virasoro) algebra is derived in the case of discrete string. • Infinite dimensional hierarchy of Poisson bracket algebras is constructed for discrete strings. • Spinor representation of discrete Frenet equations is developed.

  3. The Evolutionary Origins of Hierarchy.

    2016-06-01

    Full Text Available Hierarchical organization-the recursive composition of sub-modules-is ubiquitous in biological networks, including neural, metabolic, ecological, and genetic regulatory networks, and in human-made systems, such as large organizations and the Internet. To date, most research on hierarchy in networks has been limited to quantifying this property. However, an open, important question in evolutionary biology is why hierarchical organization evolves in the first place. It has recently been shown that modularity evolves because of the presence of a cost for network connections. Here we investigate whether such connection costs also tend to cause a hierarchical organization of such modules. In computational simulations, we find that networks without a connection cost do not evolve to be hierarchical, even when the task has a hierarchical structure. However, with a connection cost, networks evolve to be both modular and hierarchical, and these networks exhibit higher overall performance and evolvability (i.e. faster adaptation to new environments. Additional analyses confirm that hierarchy independently improves adaptability after controlling for modularity. Overall, our results suggest that the same force-the cost of connections-promotes the evolution of both hierarchy and modularity, and that these properties are important drivers of network performance and adaptability. In addition to shedding light on the emergence of hierarchy across the many domains in which it appears, these findings will also accelerate future research into evolving more complex, intelligent computational brains in the fields of artificial intelligence and robotics.

    2017-12-01

    We incorporate a clockwork mechanism into the standard model flavor sector and show that the observed pattern of fermion masses and mixing can be obtained without any unnaturally small or large parameter in the fundamental theory. By introducing Nf pairs of vectorlike fermions, as clockwork gears, for each generation of the standard model fermions and setting up a characteristic clockwork potential, it is shown that the intergenerational mass hierarchies are determined by Nf. For a given type of fermions, strong or mild hierarchy in the masses and mixing parameters can be obtained by taking the large or small value of Nf. The mechanism is shown to lead to a generalized version of the Froggatt-Nielsen mechanism as an effective description.

    Full Text Available Este ensaio procura sistematizar a análise teórica que Marx faz do pré-capitalismo e do capitalismo como estruturas sociais de poder, predominando naquele as relações políticas e neste as relações econômicas como formas de dominação. Procura-se demonstrar que no pré-capitalismo o poder político e o exercício monopolizado da violência física, social e psicológica são determinados pela forma como os agentes sociais se apropriam das condições objetivas, materiais e simbólicas da produção social. No capitalismo, a produção, quando já é comandada pelo capital, além de produzir a mais-valia, também produz um sistema de exploração geral das propriedades naturais e humanas tendo como suporte a ciência. Ou seja, ela realiza a apropriação através da ciência, e não da violência e do poder pessoal, colocando o saber científico ao seu serviço, na espécie de capital fixo. Essa extração da mais-valia assume, apesar de ser resultante da relação econômica, a forma de atividade científica. É dentro desse contexto que se analisa a questão do trabalho intelectual não só como produtor de valor mas, também, como produtor de concepções justificadoras da forma histórica de poder e de dominação capitalista.This essay aims at systematizing the theoretical analysis that Marx makes of pre-capitalism and of capitalism as social structures of power, bearing in mind that political relations predominate in the former and economic relations in the latter as forms of domination. In pre-capitalism, political power and the monopolized exercise of physical, social and psychological violence are determined by the manner in which social agents appropriate objective, material and symbolic conditions of social production. In capitalism, production, when it is already commanded by capital, on top of producing surplus value, it also produces a system of general exploitation of the natural and human properties with the support of

    2013-09-01

    The historical transition of modern medicine from an autonomous profession to a team-based interprofessional practice can be described in terms of space rather than time, with "place" as the unit of analysis. Imagining modern medicine spatially was instigated by Foucault, who described medical dominance as a territorializing of both individual body spaces and public spaces--the former through the diagnostic medical gaze, the latter in a gaze of health surveillance. However, much has happened since Foucault's (1963) analysis. The diagnostic gaze has been dispersed to develop a collaborative gaze including patients and healthcare professionals; political interests have appropriated the public health gaze; and the medical profession is subject to democratic processes of accountability. Medicine has lost its territorial imperative as new "liquid" and "nomadic" work practices emerge, making space for interprofessional care. Such dislocation of medical dominance and its multiple relocations are poorly theorised. Deleuze and Guattari distinguish between "striated" and "smooth" spaces. Striated space is associated with hierarchies and boundaries, where smooth space includes boundary crossing and democratic collaboration. Smooth or liminal spaces in hospitals, such as corridors, can paradoxically act as catalysts for collaboration or assembly democracy, affording opportunities for improvised interprofessional encounters. Such encounters can act as an antidote to planned protocols or imperatives for interprofessional collaboration.

  19. Affect and the "Really Real": The Politics of HIV/AIDS Framing in South African Theater.

    Funding in South Africa privileges HIV prevention campaigns underpinned by individual behavior change goals, despite over two decades of intervention but little reduction in national HIV prevalence. In response, civil society has begun calling for innovative interventions and ways of speaking about the epidemic. Employing framing theory, I analyze differences in how HIV/AIDS is characterized in public media and interrogate the knowledge politics underpinning a group of artists' emerging attention to the nexus of affect, intersubjectivity, and epidemics within performance. I suggest this focus challenges but also complements dominant HIV intervention models by destabilizing common content, relations of power, and hierarchies of knowledge that shape normative health discourse and practice. Simultaneously, such performances reveal deep disparities between the neoliberal principles undergirding most global public health ideology, South Africa's current political economy of HIV intervention, and the dynamic concerns of its HIV-affected constituents.

    Full Text Available I write from Prague, where, unlike in most urban formations, the main city street plays an iconic role; it references a history of political protest. However, before elaborating on the protest iconography of the Prague street, Vaclavske nam, I want to locate the ways in which the design of urban space is actualized in everyday life in the cities of the world. Three functions stand out; the first involves dwelling, the second seeing, and the third moving. With respect to the first function – dwelling – the design partitions and coordinates residential, commercial and leisure functions. At times these are organized to segregate different classes (Robert Moses’ redesign of much of New York stands out with respect to the segregation function. With respect to the second function – seeing – the design of urban space is allegiance-inspiring; it involves sight lines that afford urban dwellers and visitors views of iconic buildings and statues, which reference key founding moments in the past and/or authoritative political functions in the present (Here, L’Enfants design for Washington DC stands out as exemplary. Its manifest intention was to make the buildings housing executive, legislative and judicial functions visible from many vantage points. Rarely are the streets themselves iconic. Their dominant role is involved with the effectuation of movement. As for this third function: As Lewis Mumford famously points out, streets were once part of an asterisk design, radiating out from an exemplary, often spiritual center...

  1. Generalized NLS hierarchies from rational W algebras

    International Nuclear Information System (INIS)

    Toppan, F.

    1993-11-01

    Finite rational W algebras are very natural structures appearing in coset constructions when a Kac-Moody subalgebra is factored out. The problem of relating these algebras to integrable hierarchies of equations is studied by showing how to associate to a rational W algebra its corresponding hierarchy. Two examples are worked out, the sl(2)/U(1) coset, leading to the Non-Linear Schroedinger hierarchy, and the U(1) coset of the Polyakov-Bershadsky W algebra, leading to a 3-field representation of the KP hierarchy already encountered in the literature. In such examples a rational algebra appears as algebra of constraints when reducing a KP hierarchy to a finite field representation. This fact arises the natural question whether rational algebras are always associated to such reductions and whether a classification of rational algebras can lead to a classification of the integrable hierarchies.

    By introducing a discrete spectral problem, we derive a lattice hierarchy which is integrable in Liouville's sense and possesses a multi-Hamiltonian structure. It is show that the discrete spectral problem converges to the well-known AKNS spectral problem under a certain continuous limit. In particular, we construct a sequence of equations in the lattice hierarchy which approximates the AKNS hierarchy as a continuous limit

  4. “Coloniality of power” in East Central Europe: external penetration as internal force in post-socialist Hungarian politics

    Directory of Open Access Journals (Sweden)

    Agnes Gagyi

    2016-08-01

    Full Text Available Joining a series of analyses of effects of othering, orientalism, or coloniality in East Central Europe, the paper asks how long-term structural-ideological effects of global hierarchies, as reflected in post-colonial contexts by the term “coloniality of power,” can be conceptualized for East Central Europe. In a case study of political polarization in post-socialist Hungary,it examines the effects of global integration,  claiming that two dominant economic-political blocks formed along a division of vertical alliances related to integration with either Western or national capital. From those positions, they developed divergent political ideologies of development: modernization through Western integration, versus the protection of “national” wealth from Western capital and its local allies. While both propagated capitalist integration, they each needed to develop ideologies that appealed to electorates suffering the costs of integration. One framing of developmentalist emancipation promised Western modernity through rejection of popular, backward characteristics of the country, including nationalism. The other promised advancement in the global hierarchy through overcoming internal and external enemies of national development. These two, mutually reinforcing ideological positions, which I call“democratic antipopulism” and “antidemocratic populism,” denied the contradiction between elites’ and workers’ interest and perpetuated existing global hierarchies. Within the wider debate over cross-contextual applications of the notion of “coloniality of power,” and of emancipative efforts born from the “colonial wound,” the paper emphasizes the significance of the structural conditions, positions and alliances within which experiences of global domination are born and mobilized.

  5. Dominance as a competence domain, and the evolutionary origins of respect and contempt.

    Science.gov (United States)

    2017-01-01

    The hypothesis of a phylogenetic connection between protorespect in primate dominance hierarchies and respect in human prestige hierarchies lies in the principle that dominance is a domain of competence like others and, hence, that high-ranking primates have protoprestige. The idea that dominant primates manifest protocontempt to subordinates suggests that "looking down on" followers is intrinsic to leadership in humans, but that the expression of contempt varies critically in relation to the socioecological context.

    One main obstacle for any beyond the SM (BSM) scenario solving the hierarchy problem is its potentially large contributions to electric dipole moments. An elegant way to avoid this problem is to have the light SM fermions couple to the BSM sector only through bilinears, f̄f. This possibility can be neatly implemented in composite Higgs models. We study the implications of dynamically generating the fermion Yukawa couplings at different scales, relating larger scales to lighter SM fermions. We show that all flavor and CP-violating constraints can be easily accommodated for a BSM scale of few TeV, without requiring any extra symmetry. Contributions to B physics are mainly mediated by the top, giving a predictive pattern of deviations in ΔF=2 and ΔF=1 flavor observables that could be seen in future experiments.

    2018-01-01

    Identifying hierarchies and rankings of nodes in directed graphs is fundamental in many applications such as social network analysis, biology, economics, and finance. A recently proposed method identifies the hierarchy by finding the ordered partition of nodes which minimises a score function, termed agony. This function penalises the links violating the hierarchy in a way depending on the strength of the violation. To investigate the resolution of ranking hierarchies we introduce an ensemble of random graphs, the Ranked Stochastic Block Model. We find that agony may fail to identify hierarchies when the structure is not strong enough and the size of the classes is small with respect to the whole network. We analytically characterise the resolution threshold and we show that an iterated version of agony can partly overcome this resolution limit. PMID:29394278

    2008-08-01

    Workers of the ant Temnothorax nylanderi form dominance orders in orphaned colonies in which only one or a few top-ranking workers begin to produce males from unfertilized eggs. Between one and 11 individuals initiated 80% of all aggression in 14 queenless colonies. As predicted from inclusive fitness models (Molet M, van Baalen M, Monnin T, Insectes Soc 52:247 256, 2005), hierarchy length was found to first increase with colony size and then to level off at larger worker numbers. The frequency and skew of aggression decreased with increasing size, indicating that rank orders are less pronounced in larger colonies.

    2015-12-22

    Studies of animal behavior consistently demonstrate that the social environment impacts cooperation, yet the effect of social dynamics has been largely excluded from studies of human cooperation. Here, we introduce a novel approach inspired by nonhuman primate research to address how social hierarchies impact human cooperation. Participants competed to earn hierarchy positions and then could cooperate with another individual in the hierarchy by investing in a common effort. Cooperation was achieved if the combined investments exceeded a threshold, and the higher ranked individual distributed the spoils unless control was contested by the partner. Compared to a condition lacking hierarchy, cooperation declined in the presence of a hierarchy due to a decrease in investment by lower ranked individuals. Furthermore, hierarchy was detrimental to cooperation regardless of whether it was earned or arbitrary. These findings mirror results from nonhuman primates and demonstrate that hierarchies are detrimental to cooperation. However, these results deviate from nonhuman primate findings by demonstrating that human behavior is responsive to changing hierarchical structures and suggests partnership dynamics that may improve cooperation. This work introduces a controlled way to investigate the social influences on human behavior, and demonstrates the evolutionary continuity of human behavior with other primate species.

  14. Fermion hierarchy from sfermion anarchy

    Science.gov (United States)

    Altmannshofer, Wolfgang; Frugiuele, Claudia; Harnik, Roni

    2014-12-01

    We present a framework to generate the hierarchical flavor structure of Standard Model quarks and leptons from loops of superpartners. The simplest model consists of the minimal supersymmetric standard model with tree level Yukawa couplings for the third generation only and anarchic squark and slepton mass matrices. Agreement with constraints from low energy flavor observables, in particular Kaon mixing, is obtained for supersymmetric particles with masses at the PeV scale or above. In our framework both the second and the first generation fermion masses are generated at 1-loop. Despite this, a novel mechanism generates a hierarchy among the first and second generations without imposing a symmetry or small parameters. A second-to-first generation mass ratio of order 100 is typical. The minimal supersymmetric standard model thus includes all the necessary ingredients to realize a fermion spectrum that is qualitatively similar to observation, with hierarchical masses and mixing. The minimal framework produces only a few quantitative discrepancies with observation, most notably the muon mass is too low. We discuss simple modifications which resolve this and also investigate the compatibility of our model with gauge and Yukawa coupling Unification.

  15. Hierarchy of modular graph identities

    The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.

    We consider the topological B-model on local Calabi-Yau geometries. We show how one can solve for the amplitudes by using W-algebra symmetries which encodes the symmetries of holomorphic diffeomorphisms of the Calabi-Yau. In the highly effective fermionic/brane formulation this leads to a free fermion description of the amplitudes. Furthermore we argue that topological strings on Calabi-Yau geometries provide a unifying picture connecting non-critical (super)strings, integrable hierarchies, and various matrix models. In particular we show how the ordinary matrix model, the double scaling limit of matrix models, and Kontsevich-like matrix model are all related and arise from studying branes in specific local Calabi-Yau three-folds. We also show how A-model topological string on P^1 and local toric threefolds (and in particular the topological vertex) can be realized and solved as B-model topological string amplitudes on a Calabi-Yau manifold.

    2003-07-01

    Debate is ongoing about the nature and use of evidence in public health decision making, and there seems to be an emerging consensus that the "hierarchy of evidence" may be difficult to apply in other settings. It may be unhelpful however to simply abandon the hierarchy without having a framework or guide to replace it. One such framework is discussed. This is based around a matrix, and emphasises the need to match research questions to specific types of research. This emphasis on methodological appropriateness, and on typologies rather than hierarchies of evidence may be helpful in organising and appraising public health evidence.

    The first part of this article gives a brief overview of the four levels of the Chomsky hierarchy, with a special emphasis on context-free and regular languages. It then recapitulates the arguments why neither regular nor context-free grammar is sufficiently expressive to capture all phenomena in the natural language syntax. In the second part, two refinements of the Chomsky hierarchy are reviewed, which are both relevant to the extant research in cognitive science: the mildly context-sensitive languages (which are located between context-free and context-sensitive languages), and the sub-regular hierarchy (which distinguishes several levels of complexity within the class of regular languages).

  4. Reaching Into the Unknown: Actions, Goal Hierarchies, and Explorative Agency

    Directory of Open Access Journals (Sweden)

    Davood G. Gozli

    2018-03-01

    Full Text Available Action is widely characterized as possessing a teleological dimension. The dominant way of describing goal-directed action and agency is in terms of exploitation, i.e., pursuing pre-specified goals using existing strategies. Recent theoretical developments emphasize the place of exploration, i.e., discovering new goals or acquiring new strategies. The exploitation-exploration distinction poses questions with regard to goals and agency: Should exploration, as some authors have suggested, be regarded as acting without a goal? We argue that recognizing the hierarchical nature of goals is crucial in distinguishing the two kinds of activity, because this recognition prevents the claim that exploration is goal-free, while allowing for a homogeneous account of both exploitative and explorative actions. An action typically causes relatively low-level/proximal (i.e., sensorimotor, immediate and relatively high-level/distal (i.e., in the environment, at a wider timescale outcomes. In exploitation, one relies on existing associations between low- and high-level states, whereas in exploration one does not have the ability or intention to control high-level/distal states. We argue that explorative action entails the capacity to exercise control within the low-level/proximal states, which enables the pursuit of indeterminate goals at the higher levels of a goal hierarchy, and the possibility of acquiring new goals and reorganization of goal hierarchies. We consider how the dominant models of agency might accommodate this capacity for explorative action.

    Science.gov (United States)

    Malinowski, Elzbieta

    Data warehouses and OLAP systems form an integral part of modern decision support systems. In order to exploit both systems to their full capabilities hierarchies must be clearly defined. Hierarchies are important in analytical applications, since they provide users with the possibility to represent data at different abstraction levels. However, even though there are different kinds of hierarchies in real-world applications and some are already implemented in commercial tools, there is still a lack of a well-accepted conceptual model that allows decision-making users express their analysis needs. In this paper, we show how the conceptual multidimensional model can be used to facilitate the representation of complex hierarchies in comparison to their representation in the relational model and commercial OLAP tool, using as an example Microsoft Analysis Services.

    Directory of Open Access Journals (Sweden)

    A. J. Jacobs

    2011-01-01

    Full Text Available In agreement with Nested City theory, this paper illustrates how Japan's municipal hierarchy has evolved and remained embedded within that nation's particular historical-political-economic context. It chronicles how municipalities have attained status based upon the role they have played in the country's political, economic, and military history, and, more recently, their population size. It then shows how during the post-war period, the tiers within this urban stratification system were expanded and institutionalized by national laws governing municipalities. Drawing upon more than 100 interviews with local government officials in nine prefectures, it then reveals how a shift in national policy toward decentralization in the late-1990s sparked a race for higher municipal status in Japan's national hierarchy, during the 2000s, and thereby, local power.

    Full Text Available Walter Benjamin’s observation that fascism turns politics into aesthetics is, by now, a well-worn idea. This article argues that Benjamin’s critique of politics can apply just as much to the modern democratic politics of the United States. Borrowing from Benjamin, Jürgen Habermas, and Carl Schmitt, this article suggests that modern political discourse in the United States does not follow the classical liberal ideal of rational discourse in the marketplace of ideas within the public sphere. Instead, contemporary politics has become spectacle where images and slogans replace thought and debate in a 24/7 news cycle and political infotainment programs. The result is that progressives and conservatives have their own political “ecospheres” which enable them to have their own perspective reinforced, and debate is replaced by straw man arguments and personal attacks.

    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

    We introduce the balanced ideological antipathy (BIA) model, which challenges assumptions that right-wing authoritarianism (RWA) and social dominance orientation (SDO) predict inter-group antipathy per se. Rather, the effects of RWA and SDO on antipathy should depend on the target's political orientation and political objectives, the specific components of RWA, and the type of antipathy expressed. Consistent with the model, two studies (N = 585) showed that the Traditionalism component of RWA positively and negatively predicted both political intolerance and prejudice toward tradition-threatening and -reaffirming groups, respectively, whereas SDO positively and negatively predicted prejudice (and to some extent political intolerance) toward hierarchy-attenuating and -enhancing groups, respectively. Critically, the Conservatism component of RWA positively predicted political intolerance (but not prejudice) toward each type of target group, suggesting it captures the anti-democratic impulse at the heart of authoritarianism. Recommendations for future research on the relationship between ideological attitudes and inter-group antipathy are discussed. © 2015 by the Society for Personality and Social Psychology, Inc.

  1. Inverse gender gap in Germany: social dominance orientation among men and women.

    2011-02-01

    Across cultures studies show that men score higher on social dominance orientation than women. This gender gap is considered invariant, but conflicting explanations are discussed: Some authors refer to evolutionary psychology and perceive the gender gap to be driven by sociobiological factors. Other authors argue that social roles or gender-stereotypical self-construals encouraged by intergroup comparisons are responsible for attitudinal gender difference. In Study 1 we analyzed sex differences in social dominance orientation in three German probability surveys (each n > 2300). Unexpectedly, the analyses yielded an inverse gender gap with higher values for social dominance orientation in women than in men. Interactions with age, education, political conservatism, and perceived inequity indicated that the inverse gender gap can be mainly attributed to older, conservative, (and less educated) respondents, and those who feel they get their deserved share. In Study 2 we replicated the well-known gender gap with men scoring higher than women in social dominance orientation among German students. Results are interpreted on the basis of biocultural interaction, which integrates the sociobiological, social role, and self-construal perspectives. Our unusual findings seem to reflect a struggle for status by members of low-status groups who consider group-based hierarchy the most promising option to improve their status. While younger women take advantage of a relational, feminine self-construal that leads to lower social dominance orientation in young women than in young men, older women are supposed to profit from an agentic self-construal that results in stronger social dominance orientation values. Specific characteristics of the culture in Germany seem to promote this strategy. Here, we discuss the female ideal of the national socialist period and the agentic female social role in the post-war era necessitated by the absence of men.

    Political competitiveness - which many interpret as the degree of democracy - can be modeled as a monopolistic competition. All regimes are constrained by the threat of "entry," and thereby seek some combination of popular support and political entry barriers. This simple model predicts that many public policies are unrelated to political competitiveness, and that even unchallenged nondemocratic regimes should tax far short of their Laffer curve maximum.

    2004-08-01

    The author considered the small part of the population whose members score highly on both the Social Dominance Orientation scale and the Right-Wing Authoritarianism scale. Studies of these High SDO-High RWAs, culled from samples of nearly 4000 Canadian university students and over 2600 of their parents and reported in the present article, reveal that these dominating authoritarians are among the most prejudiced persons in society. Furthermore, they seem to combine the worst elements of each kind of personality, being power-hungry, unsupportive of equality, manipulative, and amoral, as social dominators are in general, while also being religiously ethnocentric and dogmatic, as right-wing authoritarians tend to be. The author suggested that, although they are small in number, such persons can have considerable impact on society because they are well-positioned to become the leaders of prejudiced right-wing political movements.

    2014-11-18

    Determination of the neutrino mass hierarchy (NMH) is among the most fundamental questions in particle physics. Recent measurements of 1) a large mixing angle between the first and the third neutrino mass eigenstates and 2) the first observation of atmospheric neutrino oscillations at tens of GeV with neutrino telescopes, open the intriguing new possibility to exploit matter effects in neutrino oscillation to determine the neutrino mass hierarchy. A further extension of IceCube/DeepCore called PINGU (Precision IceCube Next Generation Upgrade) has been recently envisioned with the ultimate goal to measure neutrino mass hierarchy. PINGU would consist of additional IceCube-like strings of detectors deployed in the deepest and cleanest ice in the center of IceCube. More densely deployed instrumentation would provide a threshold substantially below 10 GeV and enhance the sensitivity to the mass hierarchy signal in atmospheric neutrinos. Here we discuss an estimate of the PINGU sensitivity to the mass hierarchy determined using an approximation with an Asimov dataset and an oscillation parameter fit.

    Full Text Available This publication is a review of Herfried Münkler’s book “Empire: The logic of domination over the world - from Ancient Rome to the United States”, published in translation from German language in 2015. The reviewer describes the specifics of publication, focusing on the fact that the author analyzes in the framework of the political science discourse pressing issues regarding the development of empires as the powers affecting the militarystrategic, economic and social aspects. On the pages of his book, Münkler carefully analyzes discussions about the fate and quality of empire in the United States. H. Münkler raises questions about “boundaries of an Empire”, including those important subjects that are of great interest to political scientists who study the dynamics of relations between states and other actors in contemporary world politics. The reviewer notes that the author in the book overcomes taboo on imperial discourse in relation to modern democracies, which was initially due to the collapse of the USSR and the collapse of the Warsaw Pact, as well as the concepts of liberal democracy triumph.

  12. Does MCH play a role on establishment or maintenance of social hierarchy in Nile tilapia?

    Science.gov (United States)

    Ramanzini, Guilherme Corrêa; Volpato, Gilson Luiz; Visconti, Maria Aparecida

    2018-01-01

    Body coloration has a fundamental role in animal communication by signaling sex, age, reproductive behavior, aggression, etc. Nile-tilapia exhibits dominance hierarchy and the dominants are paler than subordinates. During social interactions in these animals, these color changes occur rapidly, and normally the subordinates become dark. In teleosteans, from the great number of hormones and neurotransmitters involved in color changes, melanocyte hormone stimulates (α-MSH) and melanin concentrates hormone (MCH) are the most remarkable. The aim of this project was to investigate the role of MCH in the establishment of hierarchical dominance of the Nile-tilapia. We analyzed the effect of background coloration in the dominance hierarchy. It was then compared to the melanophore sensibility of dominants and subordinates' fishes to MCH; finally, it was checked if the social rank affects the number of these pigment cells in dominants and subordinated fishes. Fishes which have a social hierarchy established and adjusted individually to the background exhibits paler body coloration when a visual contact was possible, independently of previous social rank and background color. Probably, even recognizing each other, fishes could be defending their new territory. Melanophores of the subordinate fishes were more sensible to MCH than dominants. It suggests that dominants fishes, which are paler than subordinates, could be under a chronic effect of MCH, which could be due a desensitization of melanophores to this hormone. The opposite effect seems to be occurring on subordinate fishes. It was not observed a significant change in the number of melanophores when the fishes were exposed to a prolonged period of agonistic interaction. It is possible that the exposure time for this interaction might not have been sufficient to have any change in the number of these cells of dominants and subordinate fishes.

    2012-01-01

    The first part of this article gives a brief overview of the four levels of the Chomsky hierarchy, with a special emphasis on context-free and regular languages. It then recapitulates the arguments why neither regular nor context-free grammar is sufficiently expressive to capture all phenomena in the natural language syntax. In the second part, two refinements of the Chomsky hierarchy are reviewed, which are both relevant to the extant research in cognitive science: the mildly context-sensitive languages (which are located between context-free and context-sensitive languages), and the sub-regular hierarchy (which distinguishes several levels of complexity within the class of regular languages).

    China's birth planning program has its own separate administrative hierarchy. The political commitment to population planning which originates with the top leadership extends to peer pressure exerted on couples at the brigade and neighborhood level. While family planning services are primarily delivered in health structures, responsibility for the population program falls to the Leading Group on Birth Planning. Not only health officials but also officials responsible for economic planning, political propaganda, scientific research, trade unions, women's affairs, and all those whose participation is considered necessary to the program's success attend meeting. The Leading Group on Birth Planning is chaired by a Vice-Premier. At each administrative level, provincial to work brigade, the same pattern is repeated: centralized responsibility combined with broad representation and high-level potitical leadership. With a tight, working structure, China has been able to enact its birth control program with remarkable speed and effectiveness. Each production brigade has its own planned birth leading group headed by the captain of the brigade or the captain of the women's team. The leading group supervises the barefoot doctors, midwives, and team level health aides who deliver contraceptives to households or accompany people to the community health center to obtain surgical services.

  18. Perceiving Groups: The People Perception of Diversity and Hierarchy.

    2018-01-15

    The visual perception of individuals has received considerable attention (visual person perception), but little social psychological work has examined the processes underlying the visual perception of groups of people (visual people perception). Ensemble-coding is a visual mechanism that automatically extracts summary statistics (e.g., average size) of lower-level sets of stimuli (e.g., geometric figures), and also extends to the visual perception of groups of faces. Here, we consider whether ensemble-coding supports people perception, allowing individuals to form rapid, accurate impressions about groups of people. Across nine studies, we demonstrate that people visually extract high-level properties (e.g., diversity, hierarchy) that are unique to social groups, as opposed to individual persons. Observers rapidly and accurately perceived group diversity and hierarchy, or variance across race, gender, and dominance (Studies 1-3). Further, results persist when observers are given very short display times, backward pattern masks, color- and contrast-controlled stimuli, and absolute versus relative response options (Studies 4a-7b), suggesting robust effects supported specifically by ensemble-coding mechanisms. Together, we show that humans can rapidly and accurately perceive not only individual persons, but also emergent social information unique to groups of people. These people perception findings demonstrate the importance of visual processes for enabling people to perceive social groups and behave effectively in group-based social interactions.

    Dopamine (DA) plays significant roles in regulation of social behavior. In social groups of humans and other animals, social hierarchy exists, which is determined by several behavioral characteristics such as aggression and impulsivity as well as social affiliations. In this study, we investigated the effects of pharmacological blockade of DA D2 receptor on social hierarchy of Japanese macaque and mouse social groups. We found acute administration of the D2 antagonist, sulpiride, in socially housed Japanese macaques attenuated social dominance when the drug was given to high social class macaques. A similar attenuation of social dominance was observed in high social class mice with D2 antagonist administration. In contrast, D2 antagonist administration in low social class macaque resulted in more stable social hierarchy of the group, whereas such effect was not observed in mouse social group. These results suggest that D2 receptor signaling may play important roles in establishment and maintenance of social hierarchy in social groups of several species of animals.

    In this note, motivated by the Kadomtsev-Petviashvili (KP) hierarchy of integrable nonlinear evolution equations, a GL(n,C) self-dual Yang-Mills (SDYM) hierarchy is presented; it is an infinite system of SDYM equations having an infinite number of independent variables and being outside of the KP hierarchy. A relationship between the KP hierarchy and the SDYM hierarchy is discussed. It is also shown that GL(∞) SDYM equations introduced in this note are reduced to the GL(n,C) SDYM hierarchy by imposing an algebraic constraint. (orig.)

  6. Disturbance of social hierarchy by an invasive species: a gene transcription study.

    Directory of Open Access Journals (Sweden)

    Christian Roberge

    Full Text Available BACKGROUND: Ecological and evolutionary changes in native populations facing invasion by exotic species are increasingly reported. Recently, it has been shown that competition with exotic rainbow trout (Oncorhynchus mykiss disrupts dominance hierarchies within groups of native Atlantic salmon (Salmo salar. The genetic and molecular actors underlying phenotypic plasticity are poorly understood. METHODOLOGY: Here, we aimed at identifying the genetic and molecular actors contributing to this plastic loss of dominance hierarchies as well as at identifying genes implicated in behaviours related to social dominance. By using microarrays, we compared the genome-wide gene transcription profiles in brains of dominant versus subordinate juvenile Atlantic salmon in presence or absence of a competitive rainbow trout. PRINCIPAL FINDINGS: Adding the trout competitor resulted in dominant and subordinate salmon being more similar, both behaviourally and at the level of brain gene transcription patterns. Genes for which transcription levels differed between dominant and subordinate salmon in the absence of exotic trout were mainly over-expressed in dominant salmon and included genes implicated in protein turnover, neuronal structural change and oxygen transport. CONCLUSIONS/SIGNIFICANCE: Our study provides one of the few examples demonstrating a close interplay between behavioural plasticity and gene transcription, therefore contributing to the understanding of the molecular mechanisms underlying these processes in an ecologically relevant context.

  12. On the Dispersal of Young Stellar Hierarchies

    Science.gov (United States)

    Elmegreen, Bruce G.

    2018-01-01

    Hierarchical structure in young star fields has been demonstrated in a variety of ways, including two-point correlation functions (TPCFs) that are power laws for spatial scales up to at least several hundred parsecs. As the stars age, this power law decreases in slope until it becomes nearly flat at ∼100 Myr, at which point the hierarchical structure has disappeared. The fact that the TPCF remains nearly a power law during this time implies that the dispersal mechanism is somewhat independent of scale. This rules out dispersal by random stellar motions at either the local gas turbulent speed or a constant speed, because in both cases the hierarchy would disappear at small scales first, causing the TPCF to bend over. Destruction by shear has the right property, as the shear rate in a galaxy is independent of scale for kiloparsec-size regions, but shear converts the hierarchy into an azimuthal stream, which still has a power-law TPCF. What does explain the observation is the overlapping of several independent hierarchies from successive generations of star formation in the same region. If stellar age is determined from magnitude intervals on the main sequence of a color–magnitude diagram, or if cluster ages are grouped together logarithmically into bins, then multiple generations will overlap more and more as the grouped populations age, and this overlap will lower the spatial correlations between group members. Models of these processes illustrate their relative roles in removing the appearance of young stellar hierarchies.

  20. Spiritual Politics

    Directory of Open Access Journals (Sweden)

    Frédéric Rambeau

    2015-01-01

    Full Text Available According to Foucault, the uprising of the Iranian people in the seventies reveals how much the political force of Islam is due precisely to the fact that it is not principally located in the field of politics, but in that of ethics. Religion (Shiite Islam appears as the guarantee of real change in the very mode of existence. This spiritual politics is marginalized by Marxism, where it is understood as a discontinuity in relation to proper politics, given that the latter is necessarily linked to a strategic rationalization. By indicating, at this juncture of what is intolerable, the living source and the critical impulse of the Foucauldian ethics, this spiritual politics also leads to recognize in the concept of “subjectivation” a dimension that might escape the circle of freedom as determined by a total immanence to power. This conceptual possibility is highly present in the aporias of the Foucauldian concept of the “relation to oneself”, both as a first condition of governmentality and the ultimate point of resistance against any governmentality. It thus reveals the difficulties in relating political to ethical subjectivation.

  1. Primate cognition and the bared-teeth display: a reevaluation of the concept of formal dominance.

    Science.gov (United States)

    Maestripieri, D

    1996-12-01

    The cognitive implications of the phenomenon of dominance in nonhuman primates and other animals have been poorly addressed. This article shows that the concept of formal dominance currently used in the primatological literature is inherently dependent on the assumption that primates are capable of attribution of knowledge to other individuals. Although this assumption has never been made explicitly, without it the concept of formal dominance is virtually indistinguishable from other, more traditional views of dominance. Recent studies have failed to demonstrate attribution of knowledge in nonhuman primates, thus questioning the validity of formal dominance. The concept of formal dominance was originally proposed to account for a discrepancy between dominance hierarchies based on aggressive behavior and dominance hierarchies based on submissive signals. This article shows that such a discrepancy can be accounted for without invoking complex cognitive processes such as attribution of knowledge.

  5. Egalitarian despots: hierarchy steepness, reciprocity and the grooming-trade model in wild chimpanzees, Pan troglodytes

    Kaburu, Stefano S. K.; Newton-Fisher, Nicholas E.

    2014-01-01

    Biological market theory models the action of natural selection as a marketplace in which animals are viewed as traders with commodities to offer and exchange. Studies of female Old World monkeys have suggested that grooming might be employed as a commodity to be reciprocated or traded for alternative services, yet previous tests of this grooming-trade model in wild adult male chimpanzees have yielded mixed results. Here we provide the strongest test of the model to date for male chimpanzees: we use data drawn from two social groups (communities) of chimpanzees from different populations and give explicit consideration to variation in dominance hierarchy steepness, as such variation results in differing conditions for biological markets. First, analysis of data from published accounts of other chimpanzee communities, together with our own data, showed that hierarchy steepness varied considerably within and across communities and that the number of adult males in a community aged 20–30 years predicted hierarchy steepness. The two communities in which we tested predictions of the grooming-trade model lay at opposite extremes of this distribution. Second, in accord with the grooming-trade model, we found evidence that male chimpanzees trade grooming for agonistic support where hierarchies are steep (despotic) and consequent effective support is a rank-related commodity, but not where hierarchies are shallow (egalitarian). However, we also found that grooming was reciprocated regardless of hierarchy steepness. Our findings also hint at the possibility of agonistic competition, or at least exclusion, in relation to grooming opportunities compromising the free market envisioned by biological market theory. Our results build on previous findings across chimpanzee communities to emphasize the importance of reciprocal grooming exchanges among adult male chimpanzees, which can be understood in a biological markets framework if grooming by or with particular individuals is

  7. Political symbols and political transitions

    Directory of Open Access Journals (Sweden)

    Herrero de Miñón, Miguel

    2006-11-01

    Full Text Available Politics, Law and Psychology are fields that come together in the symbolic. This text takes evidence from those three areas to develop an analysis of political symbols and political transitions. The development of the analysis goes through three stages. The first succinctly describes the concept of transition and its meaning. The second closely examines the notion of the symbol, in terms of its definition, to explain aspects that allow us to understand it, characterise it and make its functions clear. Finally, from the author's experience as a witness and as an actor, I suggest three ways of understanding symbols in the processes of political transition: as symbols of change, as symbols of acknowledgment, and as symbols of support.

  9. Destructiveness in Political Discourse

    2016-12-01

    Full Text Available Destructiveness is among the fundamental discourse categories that play a significant role in the organization of communicative interaction and define the pragmatics of discourse; its study helps to understand some mechanisms and principles of communication, identify strategies and tactics used by a destructive communicative personality. The relevance of this study is determined by the increasing aggressiveness in various types of discourse, and, accordingly, by the need to extend the knowledge of destructive behavior of a communicative personality. The study is based on the theory of discourse-analysis and theory of destructiveness (Z. Harris, T. van Dijk, A. Buss, E. Fromm, D. Ponton, K. Hacker, R. Wodak. N. Arutyunova, V. Karasik, M. Makarov, E. Sheigal et al. Developing the theory of destructiveness and relying on Erich Fromm’s research (1973, we specify the concept of “destructiveness” in relation to the political discourse and compare it with the related concept of aggressiveness. The paper analyses the category of destructiveness in modern US political discourse, using excerpts from the speeches of the candidates for presidency of 2016. Particular attention is paid to the dominant destructive intention - to harm the reputation of the opponent and reduce his political chances, as well as to the functions of verbal aggression: on the one hand - to discredit the opponent, bring accusations, on the other hand - to poison the audience mind against him/her and arouse the feeling of danger posed by a political opponent. The analysis of verbal and nonverbal means of destructiveness in the US political discourse is carried out. The article concludes that abusive remarks of politicians do not result from spontaneous emotional outburst, but from an elaborated destructive strategy where the agonistic nature of political discourse stipulates the use of instrumental aggression (Buss, 1971 for the sake of the conquest of power, lowering the

    Although dopamine has been suggested to play a role in mediating social behaviors of individual animals, it is not clear whether such dopamine signaling contributes to attributes of social groups such as social hierarchy. In this study, the effects of the pharmacological manipulation of dopamine D1 receptor function on the social hierarchy and behavior of group-housed mice and macaques were investigated using a battery of behavioral tests. D1 receptor blockade facilitated social dominance in mice at the middle, but not high or low, social rank in the groups without altering social preference among mates. In contrast, the administration of a D1 receptor antagonist in a macaque did not affect social dominance of the drug-treated animal; however, relative social dominance relationships between the drug-treated and nontreated subjects were altered indirectly through alterations of social affiliative relationships within the social group. These results suggest that dopamine D1 receptor signaling may be involved in social hierarchy and social relationships within a group, which may differ between rodents and primates. © The Author 2016.

We reveal a hierarchy of sensing modes (chemosensing, mechanosensing, vision, hearing, and echolocation) where body size determines the available battery of sensing modes and where larger body size means...... a longer sensing range. The size-dependent hierarchy and the transitions between primary sensory modes are explained on the grounds of limiting factors set by physiology and the physical laws governing signal generation, transmission and reception. We characterize the governing mechanisms and theoretically...... predict the body size limits for various sensory modes, which align very well with size ranges found in literature. The treatise of all ocean life, from unicellular organisms to whales, demonstrates how body size determines available sensing modes, and thereby acts as a major structuring factor of aquatic...

  12. QLC relation and neutrino mass hierarchy

    Energy Technology Data Exchange (ETDEWEB)

    Ferrandis, Javier; Pakvasa, Sandip

    2005-01-27

    Latest measurements have revealed that the deviation from a maximal solar mixing angle is approximately the Cabibbo angle, i.e., QLC relation. We argue that it is not plausible that this deviation from maximality, be it a coincidence or not, comes from the charged lepton mixing. Consequently we have calculated the required corrections to the exactly bimaximal neutrino mass matrix ansatz necessary to account for the solar mass difference and the solar mixing angle. We point out that the relative size of these two corrections depends strongly on the hierarchy case under consideration. We find that the inverted hierarchy case with opposite CP parities, which is known to guarantee the RGE stability of the solar mixing angle, offers the most plausible scenario for a high energy origin of a QLC-corrected bimaximal neutrino mass matrix. This possibility may allow us to explain the QLC relation in connection with the origin of the charged fermion mass matrices.

    The study of chemical reaction networks (CRN’s) is a very active field. Earlier well-known results (Feinberg 1987 Chem. Enc. Sci. 42 2229, Anderson et al 2010 Bull. Math. Biol. 72 1947) identify a topological quantity called deficiency, for any CRN, which, when exactly equal to zero, leads to a unique factorized steady-state for these networks. No results exist however for the steady states of non-zero-deficiency networks. In this paper, we show how to write the full moment-hierarchy for any non-zero-deficiency CRN obeying mass-action kinetics, in terms of equations for the factorial moments. Using these, we can recursively predict values for lower moments from higher moments, reversing the procedure usually used to solve moment hierarchies. We show, for non-trivial examples, that in this manner we can predict any moment of interest, for CRN’s with non-zero deficiency and non-factorizable steady states.

    2016-05-01

    Full Text Available This study presents evidence for the mediation effect of political knowledge through political self-efficacy (i.e. internal political efficacy in the prediction of political participation. It employs an action theoretic approach—by and large grounded on the Theory of Planned Behaviour—and uses data from the German Longitudinal Election Study to examine whether political knowledge has distinct direct effects on voting, conventional, and/or unconventional political participation. It argues that political knowledge raises internal political efficacy and thereby indirectly increases the chance that a citizen will participate in politics. The results of mediated multiple regression analyses yield evidence that political knowledge indeed translates into internal political efficacy, thus it affects political participation of various kinds indirectly. However, internal political efficacy and intentions to participate politically yield simultaneous direct effects only on conventional political participation. Sequentially mediated effects appear for voting and conventional political participation, with political knowledge being mediated by internal political efficacy and subsequently also by behavioural intentions. The mediation patterns for unconventional political participation are less clear though. The discussion accounts for restrictions of this study and points to questions for answer by future research.

    Full Text Available The article points out that the progressive deterioration of the social and environmental situation on the planet and the emergence of the real threat of anthropo-ecological catastrophe necessitate the abandoning of the current model of civilizational development and the formation (first in theory and then in practice of an ultimately new one. This innovative strategy, which means taking account of the main socio-natural contradiction, is called a sustainable development strategy. This new form of civilizational development must become rationally governed on a planetary scale, thus providing the survival and temporal continuation of the existence of humans and biosphere. The authors regard sustainable development as a vitally important (later on - dominating orientation of international, political and global processes. This vision makes it crucially important to embed this conception into the proper scientific disciplines and research fields. The authors make use of the A.D. Bogaturov's conceptualization approach for the scientific discipline of world politics and consider the latter as an evolutionary form of global political development. The real global integrity of the world political system serves as a global attractor of this evolutionary transformation, and this aspect represents the specific pattern of all global processes. It is supposed that these processes will unfold through transition to sustainable development. The development of the global system of political actorship is considered a fundamental process within the growth of overall complexity of the global political structure. In the evolutionary sustainable development perspective it should result in the formation of an integral subject of global politics and global activity. The article shows that the dominating state-centric approach reproduces the political model of unsustainable development, which is characterized by archaic prerequisites of political realism, spontaneous

    The interplay of social structure and cooperative behavior is under much scrutiny lately as behavior in social contexts becomes increasingly relevant for everyday life. Earlier experimental work showed that the existence of a social hierarchy, earned through competition, was detrimental for the evolution of cooperative behaviors. Here, we study the case in which individuals are ranked in a hierarchical structure based on their performance in a collective effort by having them play a Public Goods Game. In the first treatment, participants are ranked according to group earnings while, in the second treatment, their rankings are based on individual earnings. Subsequently, participants play asymmetric Prisoner's Dilemma games where higher-ranked players gain more than lower ones. Our experiments show that there are no detrimental effects of the hierarchy formed based on group performance, yet when ranking is assigned individually we observe a decrease in cooperation. Our results show that different levels of cooperation arise from the fact that subjects are interpreting rankings as a reputation which carries information about which subjects were cooperators in the previous phase. Our results demonstrate that noting the manner in which a hierarchy is established is essential for understanding its effects on cooperation.

A dominating set S such that the subgraph 〈S〉 induced by S has at least one isolated vertex is called an isolate dominating set. An isolate dominating set none of whose proper subset is an isolate dominating set is a minimal isolate dominating set. The minimum and maximum cardinality of a minimal isolate dominating set are called the isolate domination number γ0 and the upper isolate domination number Γ0 respectively. In this paper we initiate a study on these parameters.

    Full Text Available The goal of the study was to examine the political ideology and perceptions of bias among the faculty in a university in the southeast U.S.A. Findings regarding the overall dominance of a liberal political ideology as well as ideological differences among disciplines are consistent with previous research. Respondents did distinguish between political dominance and political bias and were relatively accurate in their perceptions of a liberal dominance. Reports of bias were much lower overall but all groups were more likely to report a bias against conservatives than against Liberal and Moderates. Reports of bias against conservatives were quite high among conservatives themselves (48.7%. Conservatives were more likely to report a need to conceal their political beliefs, while Moderates and Liberals were slightly more likely to report harassment or attacks for their political beliefs. The gender differences in political ideology show that women are significantly more likely to hold a liberal political ideology.

    Predation and competition are critical processes influencing the ecology of organisms, and can play an integral role in shaping coral reef fish communities. This study compared the relative and interacting effects of competition and predation on two competing species of coral reef fish, Pomacentrus amboinensis and P. moluccensis (Pomacentridae), using a multifactorial experiment. Fish were subjected to the sight and smell of a known predator (Pseudochromis fuscus), the presence of the heteros...

  17. Afterword: materialities, care, 'ordinary affects', power and politics.

    Science.gov (United States)

    Latimer, Joanna

    2018-02-01

    In this paper I explore how the papers in this volume offer ways of thinking about materialities of care in terms of political ecologies, including hierarchies of value as well as assemblages, in which strategic agendas are made present in everyday practices, with profound and ordinary affects, as well as effects. I show how power can work through the association of multiple and heterogeneous materials and social processes to create 'thresholds', as spaces through which people must pass in order to be included as patients, and which circulate specific imaginaries over what counts as an appropriate need. I go on to suggest how some material practices are made mundane and immaterial, that is inconsequential, so that by drawing attention to their importance in how care is done (or not done) the papers help disrupt the commonplace production and reproduction of the 'neglected things' (Puig de la Bellacasa ) of healthcare environments, and by so doing help reimagine what is important for occasions to actually be caring. I then shift to thinking about a sensibility, one that is highly valued in this collection of articles, that helps illuminate different imaginaries of care to those that dominate healthcare environments, an approach that I have called elsewhere 'relational extension', and in the example I offer here show how shifts in extension as a form of motility disrupts stabilities and their reproduction, to accomplish different forms of world-making. © 2018 Foundation for the Sociology of Health & Illness.

    2017-01-01

    Can a book be both inspiring and disappointing? The Real Politics of the Horn of Africa might just fall into this rare category. Alex de Waal’s writing is theoretically original and empirically rich, but it is also reductionist and, in the case of Ethiopia, biased. The book makes sense of the Horn...... of Africa’s complex contemporary politics through the prism of three elements. Firstly, de Waal proposes an innovative theory centered on the idea of the ‘political marketplace’. Secondly, as the title suggests, the book sets out to explain the Horn of Africa’s ‘real politics’, i.e. the actors, interests......, practices and dynamics that dominate political life. Individual chapters are devoted to Darfur, Sudan, South Sudan, Somalia, Somaliland, Eritrea, and Ethiopia, leaving only Djibouti out from the region. De Waal writes eloquently and with great wit, offering the reader many insights. Thirdly, The Real...

    Full Text Available Let G=(V,E be a simple graph. A set S⊆V is a dominating set of G, if every vertex in V\\S is adjacent to at least one vertex in S. Let 𝒫ni be the family of all dominating sets of a path Pn with cardinality i, and let d(Pn,j=|𝒫nj|. In this paper, we construct 𝒫ni, and obtain a recursive formula for d(Pn,i. Using this recursive formula, we consider the polynomial D(Pn,x=∑i=⌈n/3⌉nd(Pn,ixi, which we call domination polynomial of paths and obtain some properties of this polynomial.

  3. Female dominance over males in primates: self-organisation and sexual dimorphism.

    Directory of Open Access Journals (Sweden)

    Charlotte K Hemelrijk

    Full Text Available The processes that underlie the formation of the dominance hierarchy in a group are since long under debate. Models of self-organisation suggest that dominance hierarchies develop by the self-reinforcing effects of winning and losing fights (the so-called winner-loser effect, but according to 'the prior attribute hypothesis', dominance hierarchies develop from pre-existing individual differences, such as in body mass. In the present paper, we investigate the relevance of each of these two theories for the degree of female dominance over males. We investigate this in a correlative study in which we compare female dominance between groups of 22 species throughout the primate order. In our study female dominance may range from 0 (no female dominance to 1 (complete female dominance. As regards 'the prior attribute hypothesis', we expected a negative correlation between female dominance over males and species-specific sexual dimorphism in body mass. However, to our surprise we found none (we use the method of independent contrasts. Instead, we confirm the self-organisation hypothesis: our model based on the winner-loser effect predicts that female dominance over males increases with the percentage of males in the group. We confirm this pattern at several levels in empirical data (among groups of a single species and between species of the same genus and of different ones. Since the winner-loser effect has been shown to work in many taxa including humans, these results may have broad implications.

  4. Memory-Scalable GPU Spatial Hierarchy Construction.

    2011-04-01

    Recent GPU algorithms for constructing spatial hierarchies have achieved promising performance for moderately complex models by using the breadth-first search (BFS) construction order. While being able to exploit the massive parallelism on the GPU, the BFS order also consumes excessive GPU memory, which becomes a serious issue for interactive applications involving very complex models with more than a few million triangles. In this paper, we propose to use the partial breadth-first search (PBFS) construction order to control memory consumption while maximizing performance. We apply the PBFS order to two hierarchy construction algorithms. The first algorithm is for kd-trees that automatically balances between the level of parallelism and intermediate memory usage. With PBFS, peak memory consumption during construction can be efficiently controlled without costly CPU-GPU data transfer. We also develop memory allocation strategies to effectively limit memory fragmentation. The resulting algorithm scales well with GPU memory and constructs kd-trees of models with millions of triangles at interactive rates on GPUs with 1 GB memory. Compared with existing algorithms, our algorithm is an order of magnitude more scalable for a given GPU memory bound. The second algorithm is for out-of-core bounding volume hierarchy (BVH) construction for very large scenes based on the PBFS construction order. At each iteration, all constructed nodes are dumped to the CPU memory, and the GPU memory is freed for the next iteration's use. In this way, the algorithm is able to build trees that are too large to be stored in the GPU memory. Experiments show that our algorithm can construct BVHs for scenes with up to 20 M triangles, several times larger than previous GPU algorithms.

Incineration, material recycling and the distinction between non-renewable fossil fuels and renewable forest assets are incorporated. By comparing the first order conditions from the command optimum with the conditions from the market model, it is discovered that the unregulated market fails to create an optimal resource allocation. To see how the market behaves, in absence of environmental policy, compared to the first best solution a numerical model is used. Pigouvian taxes and subsidies are derived to correct for the externalities

    1992-01-01

    In the 1970s radioactive waste disposal became a controversial scientific and social issue in the United States, after the US Atomic Energy Commission (AEC) charged with the development, regulation and promotion of nuclear technology, had tried to implement its disposal technology near Lyons, Kansas. This study traces the emergence of this controversy as part of the long-term development of the US radioactive waste disposal technology. Radioactive waste was not always considered a problem, and different meanings were attached to radwaste in the 1940s and early 1950s. Problem definitions and technical designs that underlaid this technology can be reconstructed, and its possible to show how some definitions received attention and others not, and how some became, and remained, dominant. During the process of problem definition, views compete, agendas are built, resources are allocated, and boundaries are created and maintained between 'inside' and 'outside world'. This is a political process, and by heuristically using concepts from political science and recent technology studies, the Political Construction of US radioactive waste disposal technologically can be reconstructed.

    Full Text Available The first part of this text deals with a convention site selection as one of the most lucrative areas in the tourism industry. The second part gives a further description of a method for decision making - the analytic hierarchy process. The basic characteristics: hierarchy constructions and pair wise comparison on the given level of the hierarchy are allured. The third part offers an example of application. This example is solved using the Super - Decision software, which is developed as a computer support for the analytic hierarchy process. This indicates that the AHP approach is a useful tool to help support a decision of convention site selection. .

  12. When Do Types Induce the Same Belief Hierarchy?

    Directory of Open Access Journals (Sweden)

    Andrés Perea

    2016-10-01

    Full Text Available Type structures are a simple device to describe higher-order beliefs. However, how can we check whether two types generate the same belief hierarchy? This paper generalizes the concept of a type morphism and shows that one type structure is contained in another if and only if the former can be mapped into the other using a generalized type morphism. Hence, every generalized type morphism is a hierarchy morphism and vice versa. Importantly, generalized type morphisms do not make reference to belief hierarchies. We use our results to characterize the conditions under which types generate the same belief hierarchy.

    Directory of Open Access Journals (Sweden)

    Wening Udasmoro

    2018-02-01

    Full Text Available In literature, questions of the self and the other are frequently presented. The identity politics that gained prominence after the attack on the World Trade Center in New York on 11 September 2001 has occupied considerable space in this debate throughout the globe, including in France. One example of a novel dealing with the self and other is Michel Houellebecq’s Soumission (2015. This article attempts to explore the processes of selfing and othering in this work. The politics of identity that seems to present Muslims and Islam as the other and French as the self is also extended to other identities and aspects involved in the novel. This article attempts to show, first, how the French author Houellebecq positions the self and other in Soumission; second, the type of self and other the novel focuses on; and third, how its selfing and othering processes reveal the gender hierarchy and social categorization of French society. It finds that the novel presents a hierarchy in its narrative through which characters are positioned based on their gender and sexual orientation, as well as their age and ethnic heritage.

  17. Modernism and catholic political doctrine

    Directory of Open Access Journals (Sweden)

    Henry T. Sardaryan

    2017-01-01

    Full Text Available The article studies the perception of Modernism by the Catholic Church as a movement within the clerical structure and philosophy that existed during the 19-20th centuries in the framework of general skepticism and rejection of tradition, prioritization of individualism, formal equality, faith in inevitability of social, scientific and technological progress, rationalization and professionalization. A distinctive feature of this movement is the participation of the priests themselves, especially in France and Italy. The object of research is the Catholic political doctrine during the pontificate of Pius X. Modernist movement in Catholicism, in opinion of many scientists had a decisive impact on the reform direction during the Second Vatican Council, but on closer study of the discourse that took place in the late 19th - early 20th centuries, it becomes obvious that this is not true. The focus of the article is the political doctrine of Catholicism - the issue of state political structure, its relationship with church institutions, status of the individual in societyc. In this regard, the modernists gave priority to necessity of secularization and complete separation of secular and spiritual power. In the article different scientifical methods, ave used such as dialectical, logical, comparative, systematic. The main conclusion of the author is that modernism should be regarded as an unsuccessful attempt to reform the Catholic Church that could have lead to its another schism, rather than a route towards the Second Vatican Council. The desire to change the structure, methods of church mission, its hierarchy and a number of other formal elements – was implemented by church itself for multiple times before. However, revision of the foundations of Christian ethics and its ontology, including its political doctrine, ran into resistance of the Holy See, causing, in essence, a rhetorical question - whether scientific and technical progress should

    1990-01-01

    This book is a non-technical exploration of the political and policy issues that have influenced the development of nuclear power. Part One describes the successes, failures, horse-trading, and infighting that make up nuclear power's history, taking nine counties as examples. Part Two reviews the main problems that now confront us, as seen in mid-June 1990; like all contemporary accounts, the book is unavoidably incomplete. However, by then it was possible to make provisional judgements about two very important recent influences: the political consequences of Chernobyl, and concerns about the greenhouse effect. The story that emerges is of a nuclear industry that has rarely been guilty of dereliction of duty, though it was undeniably complacent in not addressing sooner the causes of the public's entirely reasonable anxieties. The anti-nuclear lobby has been skilled in debate, and sometimes extraordinarily percipient; but less than fair in failing to acknowledge the industry's achievements and its willingness to learn from past mistakes. As for the politicians, the book contains many examples that show how the flames of controversy can be deliberately fanned when there are votes to be gained. The story has few heroes, but within the industry fewer villains than the public has been led to believe. (author)

  19. Evaluating otherwise: hierarchies and opportunities in publishing practices

    Directory of Open Access Journals (Sweden)

    Derek Ruez

    2017-12-01

    Full Text Available This short paper responds to the provocations set out in Kirsi Pauliina Kallio’s recent editorial on ‘Subtle radical moves in scientific publishing’ and emerges out of my participation in a Fennia-organized panel at the 2017 Nordic Geographers’ Meeting where participants reflected on the challenges and opportunities of creating a more equitable and pluralistic international publishing environment. Given the dominance of English language publishing in international academic work and the broader geopolitics of knowledge production through which some contexts, approaches, and modes of knowledge are regularly devalued, I suggest that—to the extent that publishing outlets are evaluated or ranked—they should be evaluated and ranked, in part, based on their contribution to a pluralistically international academy. This revaluation could help shape the informal assessments made by scholars in the context of hiring, funding, and other key decisions. It could also be integrated into more formal channels, such as within the deliberations of the boards who produce publication rankings in, for example, Finland’s Publication Forum. Such a tactic need not preclude other work to contest rankings hierarchies and audit cultures as they advance the neoliberalization of academic work, but it does 1 suggest the importance of paying attention to what and how scholars value when we evaluate publishing outlets and 2 point toward the potential of critical and creative engagement with the range of processes (i.e. indexing, accrediting, measuring, ranking etc. that surround and subsist within academic publishing.

  20. Biological hierarchies and the nature of extinction.

    Science.gov (United States)

    Congreve, Curtis R; Falk, Amanda R; Lamsdell, James C

    2018-05-01

    Hierarchy theory recognises that ecological and evolutionary units occur in a nested and interconnected hierarchical system, with cascading effects occurring between hierarchical levels. Different biological disciplines have routinely come into conflict over the primacy of different forcing mechanisms behind evolutionary and ecological change. These disconnects arise partly from differences in perspective (with some researchers favouring ecological forcing mechanisms while others favour developmental/historical mechanisms), as well as differences in the temporal framework in which workers operate. In particular, long-term palaeontological data often show that large-scale (macro) patterns of evolution are predominantly dictated by shifts in the abiotic environment, while short-term (micro) modern biological studies stress the importance of biotic interactions. We propose that thinking about ecological and evolutionary interactions in a hierarchical framework is a fruitful way to resolve these conflicts. Hierarchy theory suggests that changes occurring at lower hierarchical levels can have unexpected, complex effects at higher scales due to emergent interactions between simple systems. In this way, patterns occurring on short- and long-term time scales are equally valid, as changes that are driven from lower levels will manifest in different forms at higher levels. We propose that the dual hierarchy framework fits well with our current understanding of evolutionary and ecological theory. Furthermore, we describe how this framework can be used to understand major extinction events better. Multi-generational attritional loss of reproductive fitness (MALF) has recently been proposed as the primary mechanism behind extinction events, whereby extinction is explainable solely through processes that result in extirpation of populations through a shutdown of reproduction. While not necessarily explicit, the push to explain extinction through solely population-level dynamics

    Vekslerchik, V.E.

    1998-05-01

    The aim of this paper is to summarize some recently obtained relations between the Ablowitz-Ladik hierarchy (ALH) and other integrable equations. It has been shown that solutions of finite subsystems of the ALH can be used to derive a wide range of solutions for, e.g., the 2D Toda lattice, nonlinear Schroedinger, Davey-Stewartson, Kadomtsev-Petviashvili (DP) and some other equations. Similar approach has been used to construct new integrable models: O(3,1) and multi field sigma models. Such 'universality' of the ALH becomes more transparent in the framework of the Hirota's bilinear method. The ALH, which is usually considered as an infinite set of differential-difference equations, has been presented as a finite system of functional-difference equations, which can be viewed as a generalization of the famous bilinear identities for the KP tau-functions.

  3. Dancing Twins: Stellar Hierarchies That Formed Sequentially?

    Tokovinin, Andrei

    2018-04-01

    This paper draws attention to the class of resolved triple stars with moderate ratios of inner and outer periods (possibly in a mean motion resonance) and nearly circular, mutually aligned orbits. Moreover, stars in the inner pair are twins with almost identical masses, while the mass sum of the inner pair is comparable to the mass of the outer component. Such systems could be formed either sequentially (inside-out) by disk fragmentation with subsequent accretion and migration, or by a cascade hierarchical fragmentation of a rotating cloud. Orbits of the outer and inner subsystems are computed or updated in four such hierarchies: LHS 1070 (GJ 2005, periods 77.6 and 17.25 years), HIP 9497 (80 and 14.4 years), HIP 25240 (1200 and 47.0 years), and HIP 78842 (131 and 10.5 years).

    Hierarchical structure has been cherished as a grammatical universal. We use experimental methods to show where linear order is also a relevant syntactic relation. An identical methodology and design were used across six research sites on South Slavic languages. Experimental results show that in certain configurations, grammatical production can in fact favor linear order over hierarchical structure. However, these findings are limited to coordinate structures and distinct from the kind of production errors found with comparable configurations such as "attraction" errors. The results demonstrate that agreement morphology may be computed in a series of steps, one of which is partly independent from syntactic hierarchy. Copyright © 2018 the Author(s).

  8. A Hierarchy of Homodesmotic Reactions for Thermochemistry

    Science.gov (United States)

    Schleyer, Paul v. R.

    2009-01-01

    Chemical equations that balance bond types and atom hybridization to different degrees are often used in computational thermochemistry, for example, to increase accuracy when lower levels of theory are employed. We expose the widespread confusion over such classes of equations and demonstrate that the two most widely used definitions of “homodesmotic” reactions are not equivalent. New definitions are introduced and a consistent hierarchy of reaction classes (RC1 – RC5) for hydrocarbons is constructed: isogyric (RC1) ⊇ isodesmic (RC2) ⊇ hypohomodesmotic (RC3) ⊇ homodesmotic (RC4) ⊇ hyperhomodesmotic (RC5). Each of these successively conserves larger molecular fragments. The concept of isodesmic bond separation reactions is generalized to all classes in this hierarchy, providing a unique sectioning of a given molecule for each reaction type. Several ab initio and density functional methods are applied to the bond separation reactions of 38 hydrocarbons containing five or six carbon atoms. RC4 and RC5 reactions provide bond separation enthalpies with errors consistently less than 0.4 kcal mol−1 across a wide range of theoretical levels, performing significantly better than the other reaction types and far superior to atomization routes. Our recommended bond separation reactions were demonstrated by determining the enthalpies of formation (at 298 K) of 1,3,5-hexatriyne (163.7 ± 0.4 kcal mol−1), 1,3,5,7-octatetrayne (217.6 ± 0.6 kcal mol−1), the larger polyynes C10H2 through C26H2, and an infinite acetylenic carbon chain.

    2014-11-01

    Testosterone and cortisol are hormones expected to play a major role in competitive behaviours (i.e. aggression), and are related to rank and hierarchical stability. Through a non-invasive technique, we analyzed faecal testosterone (FTM(1)) and cortisol (FCM(2)) metabolites of dominant and subordinate males from two wild groups of bearded capuchin monkeys. One group had a stable dominance hierarchy while the other had an unstable hierarchy, with a marked conflict period related to a male take-over. In the unstable hierarchy group (1) the dominant male had higher FTM peaks than subordinates, and (2) basal FTM levels were higher than in the stable group. These findings are in accordance with the Challenge Hypothesis and rank-based predictions, and confirm that in Sapajus libidinosus hierarchy stability, social status, aggression rates and testosterone are closely related. Dominants of both groups had higher basal and peak FCM levels, suggesting that in S. libidinosus the dominant male has a higher allostatic load than subordinates, related to his role in protection against predators, intragroup appeasement, and control of food sources. Finally, we suggest that males of S. libidinosus are resistant to testosterone suppression by cortisol, because in the unstable group in spite of an increase in FCM there was also an increase in FTM during the conflict period.

  19. The effects of high environmental ammonia on the structure of rainbow trout hierarchies and the physiology of the individuals therein.

    2018-02-01

    Our goals were: (i) to determine whether sublethal concentrations of water-borne ammonia would prevent the formation of a dominance hierarchy, or alter its structure, in groups of 4 juvenile trout; (ii) to investigate the behavioral and physiological responses of individuals of different social rank exposed to a concentration of ammonia that still allowed hierarchy formation. Social hierarchies were created by using a technique in which a food delivery system that created competition also served to isolate individual fish for respirometry. Groups of 4 fish were exposed to elevated ammonia (NH 4 HCO 3 ) 12 h before first feeding; aggression was recorded by video camera during morning feedings. Experimental ammonia concentrations were 700, 1200 and 1500 μmol L -1 at pH 7.3, 12 °C (9.8, 16.8, and 21.0 mg L -1 as total ammonia-N, or 0.0515, 0.0884, and 0.1105 mg L -1 as NH 3 -N). Aggression was severely reduced by 1200 and abolished by 1500 μmol L -1 total ammonia, such that hierarchies did not form. However, groups exposed to 700 μmol L -1 total ammonia still formed stable hierarchies but displayed lower levels of aggression in comparison to control hierarchies. Exposure continued for 11 days. Physiological parameters were recorded on day 5 (end of period 1) and day 10 (end of period 2), while feeding and plasma cortisol were measured on day 11. In control hierarchies, dominant (rank 1) trout generally exhibited higher growth rates, greater increases in condition factor, higher food consumption, and lower cortisol levels than did fish of ranks 2, 3, and 4. In comparison to controls, the 700 μmol L -1 total ammonia hierarchies generally displayed lower growth, lower condition factor increases, lower O 2 consumption, lower cortisol levels, but similar feeding patterns, with smaller physiological differences amongst ranks during period 1. Effects attenuated during period 2, as aggression and physiological measures returned towards

    Quantum repeaters play a significant role in achieving long-distance quantum communication. In the past decades, tremendous effort has been devoted towards constructing a quantum repeater. As one of the crucial elements, entanglement has been created in different memory systems via entanglement swapping. The realization of j-hierarchy entanglement swapping, i.e., connecting quantum memory and further extending the communication distance, is important for implementing a practical quantum repeater. Here, we report the first demonstration of a fault-tolerant two-hierarchy entanglement swapping with linear optics using parametric down-conversion sources. In the experiment, the dominant or most probable noise terms in the one-hierarchy entanglement swapping, which is on the same order of magnitude as the desired state and prevents further entanglement connections, are automatically washed out by a proper design of the detection setting, and the communication distance can be extended. Given suitable quantum memory, our techniques can be directly applied to implementing an atomic ensemble based quantum repeater, and are of significant importance in the scalable quantum information processing.

  1. Alignment hierarchies: engineering architecture from the nanometre to the micrometre scale.

    2010-12-06

    Natural tissues are built of metabolites, soluble proteins and solid extracellular matrix components (largely fibrils) together with cells. These are configured in highly organized hierarchies of structure across length scales from nanometre to millimetre, with alignments that are dominated by anisotropies in their fibrillar matrix. If we are to successfully engineer tissues, these hierarchies need to be mimicked with an understanding of the interaction between them. In particular, the movement of different elements of the tissue (e.g. molecules, cells and bulk fluids) is controlled by matrix structures at distinct scales. We present three novel systems to introduce alignment of collagen fibrils, cells and growth factor gradients within a three-dimensional collagen scaffold using fluid flow, embossing and layering of construct. Importantly, these can be seen as different parts of the same hierarchy of three-dimensional structure, as they are all formed into dense collagen gels. Fluid flow aligns collagen fibrils at the nanoscale, embossed topographical features provide alignment cues at the microscale and introducing layered configuration to three-dimensional collagen scaffolds provides microscale- and mesoscale-aligned pathways for protein factor delivery as well as barriers to confine protein diffusion to specific spatial directions. These seemingly separate methods can be employed to increase complexity of simple extracellular matrix scaffolds, providing insight into new approaches to directly fabricate complex physical and chemical cues at different hierarchical scales, similar to those in natural tissues.

    Seyfarth’s model assumes that female primates derive rank-related benefits from higher-ranking females in exchange for grooming. As a consequence, the model predicts females prefer high-ranking females as grooming partners and compete for the opportunity to groom them. Therefore, allogrooming is expected to be directed up the dominance hierarchy and to occur more often between females with adjacent ranks. Although data from Old World primates generally support the model, studies o...

  6. Property rights and hierarchies of power: a critical evaluation of land-reform policy in South Africa

    Directory of Open Access Journals (Sweden)

    André van der Walt

    1999-03-01

    Full Text Available The programme of land reform laws introduced in South Africa since 1991 is often seen and discussed as nothing more than a highly technical, black-letter aspect of South African law. In this article, the author directs attention to the policies that underly the land reform laws, and discusses the transformative potential and effect of land reform laws in view of these policies. The main question is whether the land reform programme has succeeded in breaking away from or undermining the hierarchies of power that were inherent in traditional common-law property relationships and, particularly, in the politically sanctioned and statutorily entrenched system of apartheid land law. Through the analysis of the most important land reform laws the author concludes that the land reform programme is only partially successful in this regard, since many of the new laws still uphold or entrench the underlying hierarchies o f power that characterised apartheid land law.

    Full Text Available In this work the author refers to some legal and political questions in connection with green political parties. Those questions cover: the ideology of green political parties, their number and influence, both in general and in Serbia. The first part of work is generally speaking about political parties - their definition, ideology, role and action. Main thesis in this work is that green political parties, by their appearance, were something new on the political scene. But quickly, because of objective and subjective reasons, they were changing original ideas and were beginning to resemble to all other political parties. In this way, they lost their vanguard and political alternativeness.

    The generalized Hamiltonian structures for a hierarchy of nonlinear evolution equations are established with the aid of the trace identity. Using the nonlinearization approach, the hierarchy of nonlinear evolution equations is decomposed into a class of new finite-dimensional Hamiltonian systems. The generating function of integrals and their generator are presented, based on which the finite-dimensional Hamiltonian systems are proved to be completely integrable in the Liouville sense. As an application, solutions for the hierarchy of nonlinear evolution equations are reduced to solving the compatible Hamiltonian systems of ordinary differential equations

    Understanding how medical students select their specialty is a fundamental issue for public health and educational policy makers. One of the factors that students take into account is a specialty's prestige which hinges partly on its focus on technique rather than whole person. We examine the potential of a psychological framework, social dominance theory, to explain why some students, and not others, are drawn to more prestigious, technique-oriented specialties, based on their desire for hierarchy. We conducted a cross-sectional study among medical students at Institution X (N = 359). We examined the link between medical students' characteristics i.e. social dominance orientation (SDO), gender, age, and their career intention. We also examined level of medical students' SDO at different stages of the curriculum. SDO scores were significantly associated with technique-oriented career intentions (OR 1.56; 95 % CI [1.18, 2.06]; p = 0.001). The effect was independent of gender. Medical students' SDO scores were significantly higher in later stages of the medical curriculum (F = 6.79; p = 0. 001). SDO is a significant predictor of medical students' career intention. SDO scores are higher in students during the clinical phase of the curriculum. Medical socialization, involving the internalization of implicit and explicit norms, particularly in hospital settings, is likely to underpin our findings. This theory illuminates consistent findings in the literature on specialty prestige and the influence of medical school on career choice.

    The gauge hierarchy problem is reviewed and a class of effective field theories obtained from superstrings is described. These are characterized by a classical symmetry, related to the space-time duality of string theory, that is responsible for the suppression of observable supersymmetry breaking effects. At the quantum level, the symmetry is broken by anomalies that provide the seed of observable supersymmetry breaking, and an acceptably large gauge hierarchy may be generated. 39 refs.

    We present a stronger version of the Doherty-Parrilo-Spedalieri (DPS) hierarchy of approximations for the set of separable states. Unlike DPS, our hierarchy converges exactly at a finite number of rounds for any fixed input dimension. This yields an algorithm for separability testing that is singly exponential in dimension and polylogarithmic in accuracy. Our analysis makes use of tools from algebraic geometry, but our algorithm is elementary and differs from DPS only by one simple additional collection of constraints.

  8. Reappraising the functional implications of the primate visual anatomical hierarchy.

    Science.gov (United States)

    Hegdé, Jay; Felleman, Daniel J

    2007-10-01

    The primate visual system has been shown to be organized into an anatomical hierarchy by the application of a few principled criteria. It has been widely assumed that cortical visual processing is also hierarchical, with the anatomical hierarchy providing a defined substrate for clear levels of hierarchical function. A large body of empirical evidence seemed to support this assumption, including the general observations that functional properties of visual neurons grow progressively more complex at progressively higher levels of the anatomical hierarchy. However, a growing body of evidence, including recent direct experimental comparisons of functional properties at two or more levels of the anatomical hierarchy, indicates that visual processing neither is hierarchical nor parallels the anatomical hierarchy. Recent results also indicate that some of the pathways of visual information flow are not hierarchical, so that the anatomical hierarchy cannot be taken as a strict flowchart of visual information either. Thus, while the sustaining strength of the notion of hierarchical processing may be that it is rather simple, its fatal flaw is that it is overly simplistic.

    Full Text Available This article examines the relationship between religion and the state in Indonesia by exploring how Islam is used by political parties to shape the politics. The study shows that Islamic politics is a complementary in both nationhood and statehood in Indonesia. From the early days of the new-born nation-state, Muslims in Indonesia had played significant role in shaping the nation; nonetheless, they have never dominated the political power. Fragmentation among Muslims themselves and internal political parties is among the reason why religious (Islamic parties failed in bringing religious identity to the state arena. Political subordination-inclusion-ignorance-confrontation is the circular game that features Islamic politics in Indonesia. The debatable issue on shari‘ah law, which is frequently used by Islamic parties, always becomes the core problem of the relation between Islam and the state. Even though Islam has played an important role in colouring the Indonesian politics, its existence remains complementary.

    The high per capita generation of solid waste and the environmental problems in major rural communities of Ensenada, Baja California, have prompted authorities to seek alternatives for waste treatment. In the absence of a selection methodology, three technologies of waste treatment with energy recovery (an anaerobic digester, a downdraft gasifier, and a plasma gasifier) were evaluated, taking the broader social, political, economic, and environmental issues into considerations. Using the scientific literature as a baseline, interviews with experts, decision makers and the community, and waste stream studies were used to construct a hierarchy that was evaluated by the analytic hierarchy process. In terms of the criteria, judgments, and assumptions made in the model, the anaerobic digester was found to have the highest rating and should consequently be selected as the waste treatment technology for this area. The study results showed low sensitivity, so alternative scenarios were not considered. The methodology developed in this study may be useful for other governments who wish to assess technologies to select waste treatment.

  12. Social Hierarchies, Economic Inequalities and Interpersonal Relationships: An Overview from India

    Full Text Available Abject mass poverty is of the key feature of Indian subcontinent. The relationship question, in this paper, is viewed through the lenses of poverty. Thus, the spatial, political, societal and economic questions come to picture when relationships are examined through the eyes of the poor people. Face-to-face interaction, primarily, based on strong social group collective identity is the key hallmark of relationships in India. The social group identity brings hierarchy into the interaction patterns. Thus, even market relations are not merely based on the questions of economic incentives. Social identity deeply penetrates to the huge informal economy that permeates in India. Thus, caught in the web of relationships even at market sphere, the poor people come together to fight, protest and to collaborate for their own well-being.

  14. [Dominant Thalamus and Aphasia].

    2015-12-01

    Many studies have shown that lesions of the dominant thalamus precipitate language disorders in a similar manner to transcortical aphasias, in a phenomenon known as "thalamic aphasia." In some cases, however, aphasia may not occur or may appear transiently following thalamic lesions. Furthermore, dominant thalamic lesions can produce changes in character, as observed in patients with amnesic disorder. Previous work has explored the utility of thalamic aphasia as a discriminative feature for classification of aphasia. Although the thalamus may be involved in the function of the brainstem reticular activating system and play a role in attentional network and in memory of Papez circuit or Yakovlev circuit, the mechanism by which thalamic lesion leads to the emergence of aphasic disorders is unclear. In this review, we we survey historical and recent literature on thalamic aphasia in an attempt to understand the neural processes affected by thalamic lesions.

    1990-07-01

    A family was studied in which four generations (16 of 41 members) suffered from painful recurrent muscle cramping. A clear pattern of autosomal dominant inheritance was noted. The cramping first developed during adolescence or early adulthood. Electromyographic analysis indicated a neurogenic origin. The cramps seemed to be due to dysfunction of the motor neurons. The mechanisms underlying this alteration are unclear and require further investigation.

  18. The politics of ethnicity in contemporary Miami.

    1986-01-01

    By the mid 1980s, considerably more than 750,000 Hispanics resided in the Miami metropolitan area; they comprised more than 60% of the population of Miami and over 40% of the Metro-Dade County. The Miami area population is highly segregated residentially by race and ethnicity. 3 important components of Miami's social and political structure underlie the pattern of recent ethnic politics in the Miami metropolitan area: 1) the tri-ethnic nature of the population, and the heightened sense of this ethnicity, encourages ethnic bloc voting; 2) the high degree of residential segregation not only lends strength to ethnic or racial voting blocs, but intensifies certain kinds of emotional territorial issues such as zoning or public housing location; and 3) the existing 2-tier governmental structure provides the boundaries within which the political game is played. 1 of the more interesting patterns of political change in Cuban Miami is the at 1st gradual and later more dramatic shift from exile politics to ethnic politics. The rising power of the Latin vote became apparent in the early 1970s when Maurice Ferre, of Puerto Rican background, was elected to the Miami city commission in the mid-1960s. Active participation in the political system has provided 1 means for achieving group goals, while the participation itself has stimulated the sense of ethnic identification and politicla power. It seems certain that ethnicity will dominate the political landscape in the Miami metropolitan area for some time to come.

    Full Text Available Ethics and politics are normally con­sidered domains that do not mix, in fact, domains that have little to do with one another. In this article, I provide four factual fictions that show how at the university, research ethics and politics are intertwined. Politics appears to be used for the sole purpose of constructing and maintaining con­trol over the research process and its products. Ultimately, even ethics reviews of proposed research studies are caught up in the politics of power. URN: urn:nbn:de:0114-fqs0403357

    Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

  3. Dominating biological networks.

    Directory of Open Access Journals (Sweden)

    Tijana Milenković

    Full Text Available Proteins are essential macromolecules of life that carry out most cellular processes. Since proteins aggregate to perform function, and since protein-protein interaction (PPI networks model these aggregations, one would expect to uncover new biology from PPI network topology. Hence, using PPI networks to predict protein function and role of protein pathways in disease has received attention. A debate remains open about whether network properties of "biologically central (BC" genes (i.e., their protein products, such as those involved in aging, cancer, infectious diseases, or signaling and drug-targeted pathways, exhibit some topological centrality compared to the rest of the proteins in the human PPI network.To help resolve this debate, we design new network-based approaches and apply them to get new insight into biological function and disease. We hypothesize that BC genes have a topologically central (TC role in the human PPI network. We propose two different concepts of topological centrality. We design a new centrality measure to capture complex wirings of proteins in the network that identifies as TC those proteins that reside in dense extended network neighborhoods. Also, we use the notion of domination and find dominating sets (DSs in the PPI network, i.e., sets of proteins such that every protein is either in the DS or is a neighbor of the DS. Clearly, a DS has a TC role, as it enables efficient communication between different network parts. We find statistically significant enrichment in BC genes of TC nodes and outperform the existing methods indicating that genes involved in key biological processes occupy topologically complex and dense regions of the network and correspond to its "spine" that connects all other network parts and can thus pass cellular signals efficiently throughout the network. To our knowledge, this is the first study that explores domination in the context of PPI networks.

  4. On the nesting of Painlevé hierarchies: A Hamiltonian approach

    International Nuclear Information System (INIS)

    Pickering, A.

    2012-01-01

    Highlights: ► Explanation of nesting of Painlevé hierarchies in terms of Hamiltonian structures. ► Approach generally phrased and applicable to continuous and discrete systems. ► Importance of related integrable hierarchies in understanding Painlevé hierarchies. - Abstract: We consider the phenomenon whereby two different Painlevé hierarchies, related to the same hierarchy of completely integrable equations, are such that solutions of one member of one of the Painlevé hierarchies are also solutions of a higher-order member of the other Painlevé hierarchy. An explanation is given in terms of the Hamiltonian structures of the related underlying completely integrable hierarchies, and is sufficiently generally formulated so as to be applicable equally to both continuous and discrete Painlevé hierarchies. Special integrals of a further Painlevé hierarchy related by Bäcklund transformation to the other Painlevé hierarchy mentioned above can also be constructed. Examples of the application of this approach to Painlevé hierarchies related to the Korteweg–de Vries, dispersive water wave, Toda and Volterra integrable hierarchies are considered. Our results provide further evidence of the importance of the underlying structures of related completely integrable hierarchies in understanding the properties of Painlevé hierarchies.

    2006-07-01

    Measurement of social status is an important component of many behavioural studies. A variety of techniques have been developed and adopted, but while there have been some analyses of index properties using simulated data, the rationale for selecting a method remains poorly documented. As a first step in exploring the implications of index choice, we compared the characteristics of eight popular indices by applying each to the same data set from interactions between male fowl Gallus gallus, the system in which social hierarchies were first described. Data from eight social groups, observed over four successive breeding seasons, were analysed to determine whether different indices produced consistent dominance scores. These scores were then used in tests of the relation between social status and crowing to explore whether index choice affected the results obtained. We also examined the pattern of dominance index use over the last decade to infer whether this has likely been influenced by tradition, or by taxa of study animal. Overall agreement among methods was good when groups of birds had perfectly linear hierarchies, but results diverged when social structure was more complex, with either intransitive triads or reversals. While all regression analyses revealed a positive relationship between dominance and vocal behaviour, there were substantial differences in the amount of variance accounted for, even though the original data were identical in every case. Index selection can hence perturb estimates of the importance of dominance, relative to other factors. We also found that several methods have been adopted only by particular research teams, while the use of others has been taxonomically constrained, patterns implying that indices have not always been chosen solely upon their merits. Taken together, our results read as a cautionary tale. We suggest that selection of a dominance index requires careful consideration both of algorithm properties and of the factors

  10. [In search of politics in knowledge production. A plea for a historical-political epistemology].

    Science.gov (United States)

    Roelcke, Volker

    2010-06-01

    Knowledge production has an intrinsic political dimension. Starting from this presupposition, it is argued that the systematic integration of and reflection on the political dimension is necessary for an adequate understanding of historical processes of knowledge production in the sciences. The consecutive plea for a historical-political epistemology proceeds in two steps: First, it is illustrated that in a number of recent historical science study cases, the political dimension is frequently marginal, or even absent. After a short discussion of previous theoretical concepts to describe the impact of politics for the production of scientific knowledge, an approach is sketched which builds on Hans-Jörg Rheinberger's historical epistemology and Bruno Latour's symmetrical anthropology. It is argued that in addition to Rheinberger's program to describe epistemic systems, the political dimension is intrinsic to three stages of the process of data production: First to an initial phase which consists in the arrangement socio-technical configurations to produce new evidence. Here, factors such as the culturally shaped perception and evaluation of "relevant" problems, as well as the perception of career resources have to be taken into account. Second, the political dimension is relevant in view of the continuous re-adjustments of the configuration of epistemic systems, e.g., towards newly available financial, technical, or intellectual resources and "relevant" challenges from outside the system. Thirdly, the data produced and represented by epistemic systems--"evidence"--are yet in need of interpretation. This process is in itself imbued with continuously shifting mechanisms of selecting and creating hierarchies amongst the pool of available data.

Since its introduction by Lewis (1900 and generally attributed in the marketing and advertising literature by Strong (1925, the concept of AIDA’s hierarchy of effects model has been used by many researchers, both academicians and practitioners.

    The work that established and explored the links between visual hierarchy and conceptual ontology of firearms for the purpose of threat assessment is continued. The previous study used geometrical information to find a target in the visual hierarchy and through the links with the conceptual ontology to derive high-level information that was used to assess a potential threat. Multiple improvements and new contributions are reported. The theoretical basis of the geometric feature extraction method was improved in terms of accuracy. The sample space used for validations is expanded from 31 to 153 firearms. Thus, a new larger and more accurate sequence of visual hierarchies was generated using a modified Gonzalez' clustering algorithm. The conceptual ontology is elaborated as well and more links were created between the two kinds of hierarchies (visual and conceptual). The threat assessment equation is refined around ammunition-related properties and uses high-level information from the conceptual hierarchy. The experiments performed on weapons identification and threat assessment showed that our system recognized 100% of the cases if a weapon already belongs to the ontology and in 90.8% of the cases, determined the correct third ancestor (level concept) if the weapon is unknown to the ontology. To validate the accuracy of identification for a very large data set, we calculated the intervals of confidence for our system.

    2016-01-01

    Habitat selection is an active behavioral process that may vary across spatial and temporal scales. Animals choose an area of primary utilization (i.e., home range) then make decisions focused on resource needs within patches. Dominance may affect the spatial distribution of conspecifics and concomitant habitat selection. Size-dependent social dominance hierarchies have been documented in captive alligators, but evidence is lacking from wild populations. We studied habitat selection for adult male American alligators (Alligator mississippiensis; n = 17) on the Pearl River in central Mississippi, USA, to test whether habitat selection was scale-dependent and individual resource selectivity was a function of conspecific body size. We used K-select analysis to quantify selection at the home range scale and patches within the home range to determine selection congruency and important habitat variables. In addition, we used linear models to determine if body size was related to selection patterns and strengths. Our results indicated habitat selection of adult male alligators was a scale-dependent process. Alligators demonstrated greater overall selection for habitat variables at the patch level and less at the home range level, suggesting resources may not be limited when selecting a home range for animals in our study area. Further, diurnal habitat selection patterns may depend on thermoregulatory needs. There was no relationship between resource selection or home range size and body size, suggesting size-dependent dominance hierarchies may not have influenced alligator resource selection or space use in our sample. Though apparent habitat suitability and low alligator density did not manifest in an observed dominance hierarchy, we hypothesize that a change in either could increase intraspecific interactions, facilitating a dominance hierarchy. Due to the broad and diverse ecological roles of alligators, understanding the factors that influence their social dominance

  20. Computational and Simulation Modeling of Political Attitudes: The 'Tiger' Area of Political Culture Research

    Directory of Open Access Journals (Sweden)

    Voinea, Camelia Florela

    2016-01-01

    Full Text Available In almost one century long history, political attitudes modeling research has accumulated a critical mass of theory and method. Its characteristics and particularities have often suggested that political attitude approach to political persuasion modeling reveals a strong theoretical autonomy of concept which entitles it to become a new separate discipline of research. Though this did not actually happen, political attitudes modeling research has remained the most challenging area – the “tiger” – of political culture modeling research. This paper reviews the research literature on the conceptual, computational and simulation modeling of political attitudes developed starting with the beginning of the 20th century until the present times. Several computational and simulation modeling paradigms have provided support to political attitudes modeling research. These paradigms and the shift from one to another are briefly presented for a period of time of almost one century. The dominant paradigmatic views are those inspired by the Newtonian mechanics, and those based on the principle of methodological individualism and the emergence of macro phenomena from the individual interactions at the micro level of a society. This period of time is divided in eight ages covering the history of ideas in a wide range of political domains, going from political attitudes to polity modeling. Internal and external pressures for paradigmatic change are briefly explained.

  1. The Role of Political Elites in the Development of Politics of Memory in the Baltic States

    Directory of Open Access Journals (Sweden)

    Smirnov Vadim

    2015-06-01

    Full Text Available The article focuses on multiple cases of the politicization of history by the Baltic political elites. Three states of development of politics of memory in the Baltic States are identified. Problems of political exploitation of the past are scrutinized in the context of political life and international relations. It is concluded that the narratives of the past where nazi and Soviet legacies are equated are actively promoted on the pan-European level. Elites of the Baltic States play a salient role in this process and enhance ties with the elites of the Eastern Europe, expert and political communities of the Western Europe and USA. The dominant trends in the development of the historical politics in the Baltic countries are the administrative and legislative instruments for approval of the preferred narratives of the past, as well as an active political work at the international level aimed at the inclusion of the Baltic narratives of the past into the European politics of memory. Historical politics of the Baltic States shows the Baltic countries as the victims of "two totalitarianisms" ("Nazi and Soviet occupation", and this point of view is widely used as a foreign policy tool. The politicization of the "anti-totalitarianism" issue is now a popular foreign policy tool that not only serves the interests of the Baltic and Eastern European politicians, but also finds ideological supporters in Western Europe and the United States.

    Full Text Available This essay was motivated by the gap between proclaimed democratic principles and the perceptions of politics which are exhibited by the citizens in transitional countries -more specifically in the Republic of Macedonia. It is based on research data collected in the past few decades, which illustrate that, in their political actions, the citizens are highly motivated by personal benefits and profits, rather than by their internalized values and ideologies. Non-democratic, authoritarian values prevail, while politics is perceived as a value itself, in the most materialistic meaning of the word. It creates a suitable milieu for growth of corruption, nepotism and clientelism. The authors conclude that such a circulus vitsiosus is a corner stone of the Macedonian political regime, and an enormous obstacle for the advancement of the participative, democratic political culture in reality, in spite of its formal acceptance.

  3. Social hierarchy modulates responses of fish exposed to contaminants of emerging concern.

    Full Text Available Many organisms, including the fathead minnow (Pimephales promelas, a toxicological model organism, establish social hierarchies. The social rank of each male in a population is under the control of the hypothalamic-pituitary-gonadal (HPG axis mainly through regulation of circulating androgen concentrations, which in turn drive the expression of secondary sex characteristics (SSCs. As dominant and subordinate males in an exposure study are initially under different physiological conditions (i.e., differing plasma androgen concentrations, we proposed that they belong to different subpopulations in the context of exposure to compounds that may interact with the HPG axis. Using a meta-analysis of our data from several previously published studies, we corroborated the hypothesis that social status, as indicated by SSCs, results in distinct clusters (eigenvalues >0.8 explaining >80% of variability with differential expression of plasma vitellogenin, a commonly used biomarker of exposure to contaminants of emerging concern (CEC. Furthermore, we confirmed our predictions that exposure to estrogenic CECs would homogenize plasma vitellogenin response (E1: cluster mean SSC values decreased to 4.33 and 4.86 relative to those of control; E2: decreased to 4.8 and 5.37 across the social hierarchy. In contrast, serotonin-specific reuptake inhibitors expand this response range (cluster mean SSC increased to 5.21 and 6.5 relative to those of control. Our results demonstrated that social hierarchies in male fathead minnows result in heterogeneous responses to chemical exposure. These results represent a cautionary note for the experimental design of single-sex exposure studies. We anticipate our study to be a starting point for the re-evaluation of toxicological data analyses in single sex exposure experiments.

    Dicks, Lynn V; Walsh, Jessica C; Sutherland, William J

    2014-11-01

    Making decisions informed by the best-available science is an objective for many organisations managing the environment or natural resources. Yet, available science is still not widely used in environmental policy and practice. We describe a '4S' hierarchy for organising relevant science to inform decisions. This hierarchy has already revolutionised clinical practice. It is beginning to emerge for environmental management, although all four levels need substantial development before environmental decision-makers can reliably and efficiently find the evidence they need. We expose common bypass routes that currently lead to poor or biased representation of scientific knowledge. We argue that the least developed level of the hierarchy is that closest to decision-makers, placing synthesised scientific knowledge into environmental decision support systems.

  9. Hierarchy, Violence and Bullying Among Students of Public Middle Schools

    Directory of Open Access Journals (Sweden)

    José Leon Crochík

    Full Text Available Abstract Hierarchies established in schools can lead to violence among students, particularly bullying, and this relationship is investigated in this study. A School Hierarchies Scale and a Peer Perception of Aggression Scale were applied to 274 9th grade students, both sexes, aged 14.08 years (SD = 0.81 old on average, attending four public schools in the state of São Paulo, Brazil. The students more frequently perceived to be popular, were among the best in physical education and/or among the worst in academic subjects were also more frequently perceived to be bullies, while those more frequently perceived to be unpopular and having the worst performance in physical education were also more frequently perceived to be victims. Therefore, teachers should reflect upon the issue and fight school violence that may arise from these hierarchies.

  10. Hierarchy of stability factors in reverse shoulder arthroplasty.

    Gutiérrez, Sergio; Keller, Tony S; Levy, Jonathan C; Lee, William E; Luo, Zong-Ping

    2008-03-01

    Reverse shoulder arthroplasty is being used more frequently to treat irreparable rotator cuff tears in the presence of glenohumeral arthritis and instability. To date, however, design features and functions of reverse shoulder arthroplasty, which may be associated with subluxation and dislocation of these implants, have been poorly understood. We asked: (1) what is the hierarchy of importance of joint compressive force, prosthetic socket depth, and glenosphere size in relation to stability, and (2) is this hierarchy defined by underlying and theoretically predictable joint contact characteristics? We examined the intrinsic stability in terms of the force required to dislocate the humerosocket from the glenosphere of eight commercially available reverse shoulder arthroplasty devices. The hierarchy of factors was led by compressive force followed by socket depth; glenosphere size played a much lesser role in stability of the reverse shoulder arthroplasty device. Similar results were predicted by a mathematical model, suggesting the stability was determined primarily by compressive forces generated by muscles.

    Gordoa, P. R.; Pickering, A.

    2017-10-01

    We present a new extension of the second Painlevé hierarchy and study its properties. In addition to Lax pairs, Bäcklund transformations, auto-Bäcklund transformations and basic special integrals, we also consider a new phenomenon whereby we obtain relations between systems of different orders but of the same form. The extension made here of the second Painlevé hierarchy is based on the use of non-isospectral scattering problems and so is quite general. We thus expect to be able to obtain similar extensions of other Painlevé hierarchies, including not only for continuous examples but also for discrete and differential-delay examples. We believe that our work is also of relevance for Painlevé classification, since it gives information about classes of equation that may be of interest and in addition provides a key to the possible identification of equations isolated in such a process.

    2017-08-01

    The employers in optical engineering fields hope to recruit students who are capable of applying optical principles to solve engineering problems and have strong laboratory skills. In Zhejiang University, a hierarchy curriculum for practical skill training has been constructed to satisfy this demand. This curriculum includes "Introductive practicum" for freshmen, "Opto-mechanical systems design", "Engineering training", "Electronic system design", "Student research training program (SRTP)", "National University Students' Optical-Science-Technology Competition game", and "Offcampus externship". Without cutting optical theory credit hours, this hierarchy curriculum provides a step-by-step solution to enhance students' practical skills. By following such a hierarchy curriculum, students can smoothly advance from a novice to a qualified professional expert in optics. They will be able to utilize optical engineering tools to design, build, analyze, improve, and test systems, and will be able to work effectively in teams to solve problems in engineering and design.

    1978-10-01

    The memory hierarchy is usually the largest identifiable part of a computer system and making effective use of it is critical to the operation and use of the system. The levels of such a memory hierarchy are considered and the state of the art and likely directions for both research and development are described. Algorithmic and logical features of the hierarchy not directly associated with specific components are also discussed. Among the problems believed to be the most significant are the following: (a) evaluate the effectiveness of gap filler technology as a level of storage between main memory and disk, and if it proves to be effective, determine how/where it should be used, (b) develop algorithms for the use of mass storage in a large computer system, and (c) determine how cache memories should be implemented in very large, fast multiprocessor systems

    2014-02-01

    Health care reform in Bulgaria has been ongoing for two decades. Since 1990, it has been transforming from a socialized system of medical care with free access, to one which is decentralized, includes private health care services, the general practitioner model and a National Health Insurance Fund. In this context, we are conducting an international EC Framework 7 project: 'Improving quality and safety in the hospital: The link between organizational culture, burnout, and quality of care'. We focus on health professionals' perceptions of organizational hierarchies in Bulgarian hospitals and how doctors and nurses connect these to organizational justice. We conducted seven focus groups and four interviews, with a total of 42 participants (27 nurses, 15 physicians and medical residents) in three hospitals. Data were analysed through thematic analysis and discourse analysis with Atlas.ti. From the perspective of health professionals, health reform has intensified traditional hierarchies and inequalities and has created new ones in Bulgarian hospitals. These hierarchies are continuously (re)constructed through language and practices and also destabilized through resistance. The health professionals protest fact that these hierarchies are permeated with unfairness and silence voices. All health professions (nurses, doctors, residents) in our study experience being unjustly positioned and disempowered in various hierarchies. They connect these experiences to stress and anxiety. Participatory action research needs to address multiple dimensions of organizational relationships in Bulgarian hospitals, including hierarchical relationships and ways of promoting organizational justice. What is already known on this subject? Health care organizations are hierarchically organized. Organizational injustice can contribute to burnout in health professionals. There is a high level of stress and burnout for health professionals in Bulgaria. What does this study add? This study adds

  4. Understanding Social Hierarchies: The Neural and Psychological Foundations of Status Perception

    Koski, Jessica; Xie, Hongling; Olson, Ingrid R.

    2017-01-01

    Social groups across species rapidly self-organize into hierarchies, where members vary in their level of power, influence, skill, or dominance. In this review we explore the nature of social hierarchies and the traits associated with status in both humans and nonhuman primates, and how status varies across development in humans. Our review finds that we can rapidly identify social status based on a wide range of cues. Like monkeys, we tend to use certain cues, like physical strength, to make status judgments, although layered on top of these more primitive perceptual cues are socio-cultural status cues like job titles and educational attainment. One's relative status has profound effects on attention, memory, and social interactions, as well as health and wellness. These effects can be particularly pernicious in children and adolescents. Developmental research on peer groups and social exclusion suggests teenagers may be particularly sensitive to social status information, but research focused specifically on status processing and associated brain areas is very limited. Recent evidence from neuroscience suggests there may be an underlying neural network, including regions involved in executive, emotional, and reward processing, that is sensitive to status information. We conclude with questions for future research as well as stressing the need to expand social neuroscience research on status processing to adolescents. PMID:25697184

    We study the Lindblad master equation in the space of operators and provide simple criteria for closeness of the hierarchy of equations for correlations. We separately consider the time evolution of closed and open systems and show that open systems satisfying the closeness conditions are not necessarily of Gaussian type. In addition, we show that dissipation can induce the closeness of the hierarchy of correlations in interacting quantum systems. As an example we study an interacting optomechanical model, the Fermi–Hubbard model, and the Rabi model, all coupled to a fine-tuned Markovian environment and obtain exact analytic expressions for the time evolution of two-point correlations.

    The quasiclassical solution to the extended Toda chain hierarchy, corresponding to the deformation of the simplest Seiberg-Witten theory by all descendants of the dual topological string model, is constructed explicitly in terms of the complex curve and generating differential. The first derivatives of prepotential or quasiclassical tau-function over the extra times, extending the Toda chain, are expressed through the multiple integrals of the Seiberg-Witten one-form. We derive the corresponding quasiclassical Virasoro constraints, discuss the functional formulation of the problem and propose generalization of the extended Toda hierarchy to the nonabelian theory

    The generation of exponential flavor hierarchies from extra-dimensional wave function overlaps is reexamined. We find, surprisingly, that the coexistence of anarchic fermion mass matrices with such hierarchies is intrinsic and natural to this setting. The salient features of charged fermion and neutrino masses and mixings can thereby be captured within a single framework. Both Dirac and Majorana neutrinos can be realized. Implications for a variety of weak-scale scenarios, including warped compactification and supersymmetry, are discussed. When the new weak-scale physics is sensitive to the origin of flavor structure, Dirac neutrinos are preferred.

    We introduce a parametrization of the effect of unknown corrections from new physics on quark and lepton mass matrices. This parametrization is used in order to study how the hierarchies of quark masses and mixing angles are modified by random perturbations of the Yukawa matrices. We discuss several examples of flavor relations predicted by different textures, analyzing how these relations are influenced by the random perturbations. We also comment on the unlikely possibility that unknown corrections contribute significantly to the hierarchy of masses and mixings.

    Here, we document the diversity of commercial aircraft models and bodies in use during the past five decades. Special emphasis is on the models that have moved humanity across the globe during the past three decades. The first objective is to show that the apparent diversity is in fact underpinned (sustained) by organization, which is a distinct hierarchy of "few large and many small" coexisting and moving people harmoniously everywhere. The second objective is to rely on the emerging hierarchy in order to predict for the future how few the even bigger models will be and how more numerous the even smaller models (e.g., drones for package delivery) will be, naturally.

    2000-01-01

    We perform a renormalisation group (RG) analysis of neutrino masses and mixing angles in the see-saw mechanism in the minimal supersymmetric standard model with three right-handed neutrinos, including the effects of the heavy neutrino thresholds. We focus on the case that one of the right-handed neutrinos provides the dominant contribution to the 23 block of the light Majorana matrix, causing its determinant to approximately vanish and giving an automatic neutrino mass hierarchy, so-called single right-handed neutrino dominance which may arise from a U(1) family symmetry. In these models radiative corrections can increase atmospheric and solar neutrino mixing by up to about 10% and 5%, respectively, and may help to achieve bi-maximal mixing. Significantly we find that the radiative corrections over the heavy neutrino threshold region are at least as important as those usually considered from the lightest right-handed neutrino down to low energies

  15. Dominance status predicts social fear transmission in laboratory rats.

    Jones, Carolyn E; Monfils, Marie-H

    2016-11-01

    Acquiring information about stimuli that predict danger, through either direct experience or inference from a social context, is crucial for individuals' ability to generate appropriate behaviors in response to threats. Utilizing a modified demonstrator-observer paradigm (fear conditioning by proxy) that allows for free interaction between subjects, we show that social dominance hierarchy, and the interactive social behaviors of caged rats, is predictive of social fear transmission, with subordinate rats displaying increased fear responses after interacting with a fear-conditioned dominant rat during fear retrieval. Fear conditioning by proxy conserves some of the pathways necessary for direct fear learning (e.g., lateral amygdala) but is unique in that it requires regions necessary for emotional regulation (e.g., anterior cingulate cortex), making this paradigm an important tool for evaluating learning and behavior in the laboratory setting.

    Religion and politics provide an interesting juxtaposition. On the one hand, both may initially come across as rather self-evident categories, with religion dealing with human perceptions and what people hold as sacred, and politics addressing the control and governance of fellow human beings....... Nonetheless, such a simple opposition should only work as a starting point for an interrogation of both terms and how they have come to look and function as empirical and analytical categories. Focusing on the ways that religion is played out in relation to politics reveals different historical and cultural...... constellations and positions, which can be highlighted as variations of religion as politics, religion in politics, religion out of politics, and religion not politics....

    The greatest lesson of the failure of comprehensive health reform in the early 1990s is that politics comes first. Even the best-laid policy plans are worthless if they lack the political support to pass. Putting politics first means avoiding the overarching mistake of the Clinton reformers: envisioning a grand policy compromise rather than hammering out a real political compromise. It also means addressing the inevitable fears of those who believe that they are well protected by our eroding employment-based system. And it means formulating political strategies that are premised on the contemporary realities of the hyperpolarized U.S. political environment, rather than wistfully recalled images of the bipartisan politics of old.

    In this comment, I build on Shiffman’s call for the global health community to more deeply investigate structural and productive power. I highlight two challenges we must grapple with as social scientists carrying out the types of investigation that Shiffman proposes: the politics of challenging the powerful; and the need to investigate types of expertise that have traditionally been thought of as ‘outside’ global health. In doing so, I argue that moving forward with the agenda Shiffman sets out requires social scientists interested in the global politics of health to be reflexive about our own exercise of structural and productive power and the fact that researching global health politics is itself a political undertaking.

The modern problematic of health relies upon a balance of complex relations between individual and collective acceptances of the notion. You can try to outline the evolutions and the main concepts through a quadruple approach: health and politics, health and its professionals, health and society and in the end, health and the State. The relationships between health and politics in France are affected by the historical delay of France in public health, namely because of a structural weakness of the administrative organization of public health. Nevertheless France developed a dense and well organized care system and a universal social protection against the disease. The creation of the health professions in France was marked by a historical opposition between the doctors and the state which led to a failure of hygienist medicine and a fundamental misunderstanding on health insurance. Medical domination led to the organization of a system based on professional dichotomy and the delegation of the regulation skills to the health care professionals. The role of health issues in the French society was deeply renewed by the development of the medical and epidemiological knowledge. This resulted in a new political responsibility in the management of health risks but also in the confirmation of the patients' rights and the role of their associations in the health systems operations and the piloting of public policies. In this environment, the state has recently and progressively confirmed its dominating role in the health sector. A public hospital service was created In the 60's and 70's, then in the 80's there were recurrent interventions in order to control health spendings and eventually in the 90's health safety devices were set up. More recently, a process of health policies institutionalization confirmed this evolution. In the future, health issues should

    Previous research on personality and political attitudes has been conducted in countries where political parties from the center dominate the political system. In the present research ( N = 675), we focus on the relationship between the dark side of human personality and political orientation and extremism, respectively, in the course of a presidential election where the two candidates represent either left-wing or right-wing political policies. Narcissism, Machiavellianism, psychopathy, and everyday sadism were associated with right-wing political orientation, whereas narcissism and psychopathy were associated with political extremism. Moreover, the relationships between personality and right-wing political orientation and extremism, respectively, were relatively independent from each other.

    Unsworth, Kerrie; Adriasola, Elisa; Johnston-Billings, Amber; Dmitrieva, Alina; Hodkiewicz, Melinda

    2011-01-01

    Many have recognized the need for high quality data on assets and the problems in obtaining them, particularly when there is a need for human observation and manual recording. Yet very few have looked at the role of the data collectors themselves in the data quality process. This paper argues that there are benefits to more fully understanding the psychological factors that lay behind data collection and we use goal hierarchy theory to understand these factors. Given the myriad of potential reasons for poor-quality data it has previously proven difficult to identify and successfully deploy employee-driven interventions; however, the goal hierarchy approach looks at all of the goals that an individual has in their life and the connections between them. For instance, does collecting data relate to whether or not they get a promotion? Stay safe? Get a new job? and so on. By eliciting these goals and their connections we can identify commonalities across different groups, sites or organizations that can influence the quality of data collection. Thus, rather than assuming what the data collectors want, a goal hierarchy approach determines that empirically. Practically, this supports the development of customized interventions that will be much more effective and sustainable than previous efforts. - Highlights: → We need to consider psychological aspects of data collectors to improve data quality. → We show how goal hierarchy theory furthers understanding. → Looks at the multiple goals of each individual to determine their behavior.

    2017-10-01

    We study the effect of nonstandard interactions (NSIs) on the propagation of neutrinos through the Earth's matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize the special case when the diagonal NSI parameter ɛe e=-1 , nullifying the standard matter effect. We show that if, in addition, C P violation is maximal then this gives rise to an exact intrinsic hierarchy degeneracy in the appearance channel, irrespective of the baseline and energy. Introduction of the off diagonal NSI parameter, ɛe τ, shifts the position of this degeneracy to a different ɛe e. Moreover the unknown magnitude and phases of the off diagonal NSI parameters can give rise to additional degeneracies. Overall, given the current model independent limits on NSI parameters, the hierarchy sensitivity of DUNE can get seriously impacted. However, a more precise knowledge of the NSI parameters, especially ɛe e, can give rise to an improved sensitivity. Alternatively, if a NSI exists in nature, and still DUNE shows hierarchy sensitivity, certain ranges of the NSI parameters can be excluded. Additionally, we briefly discuss the implications of ɛe e=-1 (in the Earth) on the Mikheyev-Smirnov-Wolfenstein effect in the Sun.

  18. Grooming up the hierarchy: the exchange of grooming and rank-related benefits in a new world primate.

    Directory of Open Access Journals (Sweden)

    Barbara Tiddi

    Full Text Available Seyfarth's model assumes that female primates derive rank-related benefits from higher-ranking females in exchange for grooming. As a consequence, the model predicts females prefer high-ranking females as grooming partners and compete for the opportunity to groom them. Therefore, allogrooming is expected to be directed up the dominance hierarchy and to occur more often between females with adjacent ranks. Although data from Old World primates generally support the model, studies on the relation between grooming and dominance rank in the New World genus Cebus have found conflicting results, showing considerable variability across groups and species. In this study, we investigated the pattern of grooming in wild tufted capuchin females (Cebus apella nigritus in Iguazú National Park, Argentina by testing both the assumption (i.e., that females gain rank-related return benefits from grooming and predictions (i.e., that females direct grooming up the dominance hierarchy and the majority of grooming occurs between females with adjacent ranks of Seyfarth's model. Study subjects were 9 adult females belonging to a single group. Results showed that grooming was given in return for tolerance during naturally occurring feeding, a benefit that higher-ranking females can more easily grant. Female grooming was directed up the hierarchy and was given more often to partners with similar rank. These findings provide supporting evidence for both the assumption and predictions of Seyfarth's model and represent, more generally, the first evidence of reciprocal behavioural interchanges driven by rank-related benefits in New World female primates.

    2016-10-01

    Full Text Available The public sphere of politics as a theoretical concept of modern political science has been discussed in the article. The reasons of the increasing interest to the public sphere is a dominating subject. Studied The phenomenon of the public sphere being a tool of theoretical and methodological definition of the political world’s boundaries has been studied. The value aspects of media activity in the contemporary politics has been investigated. An attempt has been made to establish the potential of political publicity for the qualitative understanding of participatory democracy. The potential of the public sphere in the development of civil society and social capital has been described. The distinction between the public sphere of politics and political communication in the specific conditions of modern transformational societies has been reasonably grounded. The importance of the presence of state power in all spheres of life of the transformational society has been stressed. Such transformation has not been stoped after the liberal market reforms, which had to ensure the existence of a formal representative democracy. The influence of the elite and expert groups being the reason of the absence of really functioning future civil society has been considered. The features of the formation of civil and social activities as a precondition for the democratic political class’ functioning have been studied. The specifics of public political activity being the prerogative of the competent entities’ political broadcasting have been analyzed. The gradual formation of cyber public sphere and its political branch segment has been revealed. Thorough attention has been given to the processes of the public sphere’s politicization which are usual for primarily authoritarian and closed societies.

    The inverse association between socioeconomic position (SEP) and cardiovascular disease may involve social psychophysiological processes. To test effects of aspects of SEP on physiological reactivity, we experimentally manipulated 3 features of social context related to social hierarchy-social rank or status relative to an interaction partner, the partner's degree of dominant behavior, and the presence of social-evaluative threat. The study design was a 2 × 2 × 2 × 2 (Participant Relative Status [high vs. low] × Partner Dominance [high vs. low] × Evaluative Threat [high vs. low] × Sex [male vs. female]) factorial, and 180 undergraduates participated. Cardiovascular and salivary cortisol responses were measured while participants engaged in a controlled interaction task with a prerecorded confederate partner. Lower participant relative status resulted in greater increases in systolic (SBP) and diastolic blood pressure (DBP). Interacting with a more dominant partner resulted in greater increases in SBP and heart rate (HR), and larger changes in cardiac sympathetic and parasympathetic activation. Higher levels of social-evaluative threat evoked larger increases in HR and SBP. In some cases, these effects were stronger in men than in women, and aspects of the low status social context had synergistic effects on some physiological outcomes. Interpersonal interactions and experiences may contribute to the association between SEP and cardiovascular health through the mechanism of physiological activation. Recurring patterns of everyday social experiences and their physiological effects may be a pathway linking the broader social context to cardiovascular disease.

While MGIMO-University is celebrating its 70th anniversary the Department of Political Sciences turns 15. Despite the fact that political analyst is a relatively new profession in Russia, it acquired a legal standing only in the 1990s, the political science school at MGIMO-University is almost as old as the university itself. Unlike many other universities, focused on the training teachers of political science or campaign managers MGIMO-University has developed its own unique political science school of "full cycle", where students grow into political sciences from a zero level up to the highest qualifications as teachers and researchers, and campaign managers, consultants and practitioners. The uniqueness of the school of political science at MGIMO-University allows its institutional incarnation -the Department of Political Science - to offer prospective studentsa training in a wide range of popular specialties and specializations, while ensuring a deep theoretical and practical basis of the training. Studying at MGIMO-University traditionally includes enhanced linguistic component (at least two foreign languages. For students of international relations and political science learning foreign languages is particularly important.It allows not only to communicate, but also to produce expertise and knowledge in foreign languages.

    Exploring the apparent tension between Foucault's analyses of technologies of domination -- the ways in which the subject is constituted by power-knowledge relations -- and of technologies of the self -- the ways in which individuals constitute themselves through practices of freedom -- this article endeavors to make two points: first, the interpretive claim that Foucault's own attempts to analyse both aspects of the politics of our selves are neither contradictory nor incoherent; and second, the constructive claim that Foucault's analysis of the politics of our selves, though not entirely satisfactory as it stands, provides important resources for the project of critical social theory.

  6. Fibrous Protein Structures: Hierarchy, History and Heroes.

    Squire, John M; Parry, David A D

    2017-01-01

    During the 1930s and 1940s the technique of X-ray diffraction was applied widely by William Astbury and his colleagues to a number of naturally-occurring fibrous materials. On the basis of the diffraction patterns obtained, he observed that the structure of each of the fibres was dominated by one of a small number of different types of molecular conformation. One group of fibres, known as the k-m-e-f group of proteins (keratin - myosin - epidermin - fibrinogen), gave rise to diffraction characteristics that became known as the α-pattern. Others, such as those from a number of silks, gave rise to a different pattern - the β-pattern, while connective tissues yielded a third unique set of diffraction characteristics. At the time of Astbury's work, the structures of these materials were unknown, though the spacings of the main X-ray reflections gave an idea of the axial repeats and the lateral packing distances. In a breakthrough in the early 1950s, the basic structures of all of these fibrous proteins were determined. It was found that the long protein chains, composed of strings of amino acids, could be folded up in a systematic manner to generate a limited number of structures that were consistent with the X-ray data. The most important of these were known as the α-helix, the β-sheet, and the collagen triple helix. These studies provided information about the basic building blocks of all proteins, both fibrous and globular. They did not, however, provide detailed information about how these molecules packed together in three-dimensions to generate the fibres found in vivo. A number of possible packing arrangements were subsequently deduced from the X-ray diffraction and other data, but it is only in the last few years, through the continued improvements of electron microscopy, that the packing details within some fibrous proteins can now be seen directly. Here we outline briefly some of the milestones in fibrous protein structure determination, the role of the

    Full Text Available Thanks to different mass media sources, members of any society are well aware of political developments and events and politicians. Every person has his or her own formed political beliefs and affirmations, interpreters other people's actions during political developments and evaluates events that take place. Political forces, in turn, see a person (a potential elector as an object of external information influence. This lets them use political communication when competing for the power. In the modern democratic society this competition is carried out via parliamentarian debates, politicians' speeches, examining political parties' programs, political agitation and voting. General audience-oriented political discourse implements its function of political information influence. As the goal of any political party's program (as an independent form of text in the system of political discourse is to win the elections and come to power, thus the audience influence function is one of the most fundamental and serve as the basis for the text. The text of a program itself is characterized by its persuasive orientation towards the audience, which reveal itself in such methods as convincing, argumentation, manipulation and evaluation. All the political programs pertain to parties which are at the power or which are in opposition. The main characteristic of oppositional programs is the criticism of the power, vice versa, the dominant party's programs confirm the correctness of their policy. All the political programs are multi-authored. The written form of any political program lets put into practice a detailed text analysis. This article presents the analysis of the texts of two leading Spanish political parties (the Spanish socialist worker's party and the people's party of Spain.

  10. Does Social Media Benefit Dominant or Alternative Water Discourses?

    Full Text Available Political ecology and cognate fields have highlighted the social constructedness of different water discourses, exposing them as the product of a particular view of nature with underpinning interests and political consequences. Integrated Water Resources Management, technical approaches, or the privatisation of drinking water services have enjoyed dominant positions, being able to determine what constitutes common sense. This has excluded numerous other alternative approaches, such as those championed by indigenous peoples. Social media, through its easy accessibility and its emphasis on visual, interactive, and short communication forms, bears the promise to challenge dominant discourses. Whether social media benefits dominant or alternative discourses has not yet been explored by the political ecology literature to which this article contributes. The article conducts a qualitative analysis of the use of two of the main social networking services (Facebook and Twitter by nine organisations working on water. Organisations were selected considering their likelihood to champion different water discourses. The article analyses the formats used, the place of communities, and the kind of language employed. It argues that while social media presents an interesting potential for alternative discourses, it also offers important tools for dominant discourses to consolidate themselves. The article concludes that social media does not structurally challenge the status quo and suggests avenues for future research.

  11. Gender, risk assessment, and political ambition.

    In the United States, women have long held the right to vote and can participate fully in the political process, and yet they are underrepresented at all levels of elected office. Worldwide, men's dominance in the realm of politics has also been the norm. To date, scholars have focused on supply-side and demand-side explanations of women's underrepresentation but differences in how men and women assess electoral risk (the risk involved in seeking political office) are not fully explained. To fill this gap, I explore how evolutionary theory offers insights into gendered differences in political ambition and the evaluation of electoral risk. Using the framework of life-history theory, I hypothesize that both cognitive and environmental factors in human evolution, particularly as they relate to sexual selection and social roles, have shaped the psychology of ambition in gendered ways affecting contemporary politics. Cognitive risk-assessment mechanisms evolving in the hominid line came to be expressed differently in females and males, in women and men. These gendered expressions plausibly reflect differentiable environmental pressures in the past and may help explain behaviors in and barriers to women's electoral political activity in the present. If so, then the success of efforts to increase such activity - or, regressively, to suppress it - may be better understood.

    A wide class of N=2 reductions of the supersymmetric KP hierarchy in N=1 superspace is described. This class includes a new N=2 supersymmetric generalization of the Toda chain hierarchy. The Lax pair representations of the bosonic and fermionic flows, local and nonlocal Hamiltonians, finite and infinite discrete symmetries, first two Hamiltonian structures and the recursion operator of this hierarchy are constructed. Its secondary reduction to new N=2 supersymmetric modified KdV hierarchy is discussed

  15. Perfect secure domination in graphs

    S.V. Divya Rashmi

    2017-07-01

    Full Text Available Let $G=(V,E$ be a graph. A subset $S$ of $V$ is a dominating set of $G$ if every vertex in $Vsetminus  S$ is adjacent to a vertex in $S.$ A dominating set $S$ is called a secure dominating set if for each $vin Vsetminus S$ there exists $uin S$ such that $v$ is adjacent to $u$ and $S_1=(Ssetminus{u}cup {v}$ is a dominating set. If further the vertex $uin S$ is unique, then $S$ is called a perfect secure dominating set. The minimum cardinality of a perfect secure dominating set of $G$ is called the perfect  secure domination number of $G$ and is denoted by $gamma_{ps}(G.$ In this paper we initiate a study of this parameter and present several basic results.

    The aim of this study was to examine the complex interactions between political traditions, policies, and public health outcomes, and to find out whether different political traditions have been associated with systematic patterns in population health over time. We analysed a number of political, economic, social, and health variables over a 50-year period, in a set of wealthy countries belonging to the Organisation for Economic Co-operation and Development (OECD). Our findings support the hypothesis that the political ideologies of governing parties affect some indicators of population health. Our analysis makes an empirical link between politics and policy, by showing that political parties with egalitarian ideologies tend to implement redistributive policies. An important finding of our research is that policies aimed at reducing social inequalities, such as welfare state and labour market policies, do seem to have a salutary effect on the selected health indicators, infant mortality and life expectancy at birth.

  5. Total Domination Versus Paired-Domination in Regular Graphs

    Directory of Open Access Journals (Sweden)

    Cyman Joanna

    2018-05-01

    Full Text Available A subset S of vertices of a graph G is a dominating set of G if every vertex not in S has a neighbor in S, while S is a total dominating set of G if every vertex has a neighbor in S. If S is a dominating set with the additional property that the subgraph induced by S contains a perfect matching, then S is a paired-dominating set. The domination number, denoted γ(G, is the minimum cardinality of a dominating set of G, while the minimum cardinalities of a total dominating set and paired-dominating set are the total domination number, γt(G, and the paired-domination number, γpr(G, respectively. For k ≥ 2, let G be a connected k-regular graph. It is known [Schaudt, Total domination versus paired domination, Discuss. Math. Graph Theory 32 (2012 435–447] that γpr(G/γt(G ≤ (2k/(k+1. In the special case when k = 2, we observe that γpr(G/γt(G ≤ 4/3, with equality if and only if G ≅ C5. When k = 3, we show that γpr(G/γt(G ≤ 3/2, with equality if and only if G is the Petersen graph. More generally for k ≥ 2, if G has girth at least 5 and satisfies γpr(G/γt(G = (2k/(k + 1, then we show that G is a diameter-2 Moore graph. As a consequence of this result, we prove that for k ≥ 2 and k ≠ 57, if G has girth at least 5, then γpr(G/γt(G ≤ (2k/(k +1, with equality if and only if k = 2 and G ≅ C5 or k = 3 and G is the Petersen graph.

    Full Text Available This paper considers the concept of political community, its constitution and value. The starting point is that the concept of community is not sufficiently recognized in modern political theories, as well as in contemporary liberal theory. In the last two decades communitarian and republican political theory attempted to revitalize this notion. The first part of the paper elaborates on the polemics between these three theoretical orientations. The concluding part examines the possibilities and prospect for stable political community in conditions of pluralism of particular social communities and ethnocultural heterogeneity.

    In the last 5 years, the phrase “politics of envy” has appeared more than 621 times in English-language newspapers, generally in opinion essays contending that political liberalism reflects and exploits feelings of envy. Oddly, this assertion has not been tested empirically. We did so with a large adult sample (n = 357). Participants completed a Dispositional Envy Scale and questions about political ideology, socioeconomic status, and age. Envy and age were moderately correlated; younger people reported greater envy. Political ideology and envy were weakly correlated; however, this relationship was not significant when controlling for age. PMID:23471177

    2015-12-01

    Full Text Available New institutional politics is an interdisciplinary movement that tries to reinstate the institutional politics to the center of the political science. After the limits of formal-legal analyze, used by old institutional politics, have been criticized by behaviorists, rational choice and neo-Marxist movements, since 1950, the state was alienated from the center of the political studies as an independent variable. Since 1980, neo institutional politics, raised as a reaction to this development, has been developing a new description and understanding of the institution which goes beyond the limitations of the old one. The rise and change of the political institutions and the interactions between political institutions and the actors, are being retheorized, by depending on informal rules and conventions as much as formal rules, and pointing out cultural factors as much as legal factors. So, in this study, rational choice, sociological and historical new institutional politics, as the three different school of new institutionalism, will be examined separately and there will be a debate on colliding and overlapping points of these schools

    The relationship between astronomy and politics is a complex but important part of understanding the practice of astronomy throughout history. This chapter explores some of the ways that astronomy, astrology, and politics have interacted, placing particular focus on the way that astronomy and astrology have been used for political purposes by both people in power and people who wish to influence a ruler's policy. Also discussed are the effects that politics has had on the development of astronomy and, in particular, upon the recording and preservation of astronomical knowledge.

  12. Dominant rats are natural risk takers and display increased motivation for food reward.

    2009-08-04

    Risk-taking behavior is a vital aspect mediating the formation of social structure in animals. Here, we utilized the visible burrow system (VBS), a model in which rats form dominance hierarchies, to test the hypothesis that dominant rats in the VBS are natural risk takers and display an increased motivational state after VBS exposure. In particular, we predicted that dominant rats would have attenuated anxiety-like behavior and augmented acquisition of operant responding for food reward relative to subordinate and controls. We further hypothesized that these behaviors would correlate with elevated mesocortical orexin signaling. Prior to burrow exposure, male Long-Evans rats were tested on the elevated plus maze (EPM), and subsequently exposed to the VBS for seven consecutive days. At the conclusion of burrow exposure body weight and plasma corticosterone were used to confirm social rank within each colony. Interestingly, rats that went on to become dominant in the VBS spent significantly more time in the open arms of the EPM prior to burrow exposure and displayed increased operant responding for food reward. This effect was present over a range of reinforcement schedules and also persisted for up to 1 month following VBS exposure. Moreover, dominant rats displayed increased orexin receptor mRNA in the medial prefrontal cortex (mPFC) relative to subordinate and control rats. These data support previous findings from our group and are consistent with the hypothesis that risk-taking behavior may precede dominance formation in social hierarchies.

  13. Personality predicts social dominance in male domestic fowl.

    Directory of Open Access Journals (Sweden)

    Anna Favati

    Full Text Available Individuals in social species commonly form dominance relationships, where dominant individuals enjoy greater access to resources compared to subordinates. A range of factors such as sex, age, body size and prior experiences has to varying degrees been observed to affect the social status an individual obtains. Recent work on animal personality (i.e. consistent variation in behavioural responses of individuals demonstrates that personality can co-vary with social status, suggesting that also behavioural variation can play an important role in establishment of status. We investigated whether personality could predict the outcome of duels between pairs of morphologically matched male domestic fowl (Gallus gallus domesticus, a species where individuals readily form social hierarchies. We found that males that more quickly explored a novel arena, or remained vigilant for a longer period following the playback of a warning call were more likely to obtain a dominant position. These traits were uncorrelated to each other and were also uncorrelated to aggression during the initial part of the dominance-determining duel. Our results indicate that several behavioural traits independently play a role in the establishment of social status, which in turn can have implications for the reproductive success of different personality types.

    Full Text Available Multi-party political system led to competition between political parties which caused the need for marketing in politics that improves political reputation. Politics, based on rich experience of political practice, used existing, developed methods and techniques of commercial marketing. Political marketing openly admits that politics and politicians are simply goods that are being sold on a political market. Political marketing is a whole way of operation by political parties which ask these questions: how do the voters choose; what affects their preference and how that preference can be influenced. Usage of political marketing in Bosnia and Herzegovina is still not on a satisfactory level but the knowledge about the importance of political marketing is increasing.

    Full Text Available In urban spatial planning, the Local Government prioritizes land use to support planning development. The use of available land in an area must be adjusted to the function. So far, sometimes in an area the use of available land in an area does not fit with its function. Therefore, in this research will be determined the priority and ranking of land use by using Analytic Hierarchy Process (AHP. Ranking is based on four aspect criterias: social demography, economic, spatial and regional plan (RTRW, and environmental aspect. Based on the alternatives and criteria and also subcriteria, the decision hierarchy model is made. Then it will be assessed for the comparison between criterias and subcriterias and their consistency value. The result is achieved by using Expert Choice software version 11 and analysis, it showed that the main priority of land allocation in Sidoarjo regency was used as agricultural land (31.9%.

  18. Fuzzy Analytical Hierarchy Process for Ecological Risk Assessment

    Directory of Open Access Journals (Sweden)

    Radionovs Andrejs

    2016-12-01

    Full Text Available Being able to evaluate risks is an important task in many areas of human activity: economics, ecology, etc. Usually, environmental risk assessment is carried out on the basis of multiple and sometimes conflicting factors. Using multiple criteria decision-making (MCDM methodology is one of the possible ways to solve the problem. Analytic hierarchy process (AHP is one of the most commonly used MCDM methods, which combines subjective and personal preferences in the risk assessment process. However, the AHP involves human subjectivity, which introduces vagueness type of uncertainty and requires the use of decision making under those uncertainties. In this paper, work with uncertainty is considered using fuzzy-based techniques. The paper also analyses the ecological risk assessment towards human health in case of gaseous substance escape at a chemical factory using the fuzzy analytical hierarchy process.

    The recent discovery by the Daya-Bay and RENO experiments, that θ(13) is nonzero and relatively large, significantly impacts existing experiments and the planning of future facilities. In many scenarios, the nonzero value of θ(13) implies that θ(23) is likely to be different from π/4. Additionally, large detectors will be sensitive to matter effects on the oscillations of atmospheric neutrinos, making it possible to determine the neutrino mass hierarchy and the octant of θ(23). We show that a 50 kT magnetized liquid argon neutrino detector can ascertain the mass hierarchy with a significance larger than 4σ with moderate exposure times, and the octant at the level of 2-3σ with greater exposure.

  20. Mass formulae and natural hierarchy in string effective supergravities

    Ferrara, Sergio; Zwirner, Fabio

    1995-01-01

    We study some conditions for the hierarchy m_{3/2} << M_P to occur naturally in a generic effective supergravity theory. Absence of fine-tuning and perturbative calculability require that the effective potential has a sliding gravitino mass and vanishing cosmological constant, up to {\\cal O}(m_{3/2}^4) corrections. In particular, cancellation of quadratically divergent contributions to the one-loop effective potential should take place, including the "hidden sector" of the theory. We show that these conditions can be met in the effective supergravities derived from four-dimensional superstrings, with supersymmetry broken either at the string tree level via compactification, or by non-perturbative effects such as gaugino condensation. A crucial role is played by some approximate scaling symmetries, which are remnants of discrete target-space dualities in the large moduli limit. We derive explicit formulae for the soft breaking terms arising from this class of "large hierarchy compatible" (LHC) supergravi...

    Short-wave perturbations in a relaxing medium, governed by a special reduction of the Ostrovsky evolution equation, and later derived by Whitham, are studied using the gradient-holonomic integrability algorithm. The bi-Hamiltonicity and complete integrability of the corresponding dynamical system is stated and an infinite hierarchy of commuting to each other conservation laws of dispersive type are found. The well defined regularization of the model is constructed and its Lax type integrability is discussed. A generalized hydrodynamical Riemann type system is considered, infinite hierarchies of conservation laws, related compatible co-symplectic structures and Lax type representations for the special cases N = 2, 3 and N = 4 are constructed.

  3. Mass hierarchies from anomalies: A peek behind the Planck curtain

    International Nuclear Information System (INIS)

    Ramond, P.

    1996-01-01

    The masses of quarks and leptons suggest a strong hierarchical structure. We argue that their patterns can be reproduced through the introduction of a new Abelian symmetry. The data suggest that this symmetry is anomalous. We suggest that the cancellation of its anomalies occurs through the Green-Schwarz mechanism. An important check of this idea is that it links the Weinberg angle to a mass ration of the elementary fermions. The Green-Schwarz mechanism occurs naturally in many superstring compactifications, and produces a small parameter, which we use to determine the quark mass hierarchy. We show that hierarchy and mixings among the chiral fermions is a consequence of the Green-Schwarz mechanism. We present several models where this idea is realized. 16 refs., 2 tabs

  4. Entangled parametric hierarchies: problems for an overspecified universal grammar.

    Boeckx, Cedric; Leivada, Evelina

    2013-01-01

    This study addresses the feasibility of the classical notion of parameter in linguistic theory from the perspective of parametric hierarchies. A novel program-based analysis is implemented in order to show certain empirical problems related to these hierarchies. The program was developed on the basis of an enriched data base spanning 23 contemporary and 5 ancient languages. The empirical issues uncovered cast doubt on classical parametric models of language acquisition as well as on the conceptualization of an overspecified Universal Grammar that has parameters among its primitives. Pinpointing these issues leads to the proposal that (i) the (bio)logical problem of language acquisition does not amount to a process of triggering innately pre-wired values of parameters and (ii) it paves the way for viewing language, epigenetic ('parametric') variation as an externalization-related epiphenomenon, whose learning component may be more important than what sometimes is assumed.

    The emergence of large communities is inherently associated with the creation of social structures. Connections between individuals are indispensable for cooperative action of agents building social groups. Moreover, social groups usually evolve and their structure changes over time. Consequently, an underlying network connecting individuals is not static, reflecting an ongoing adaptation to new conditions. The evolution of social connections is influenced by the relative position (hierarchy) of individuals building the system as well as by the availability of resources. We explore this aspect of human ambition by modeling the interplay of social networking and an uneven distribution of external resources. The model naturally generates social hierarchies. Remarkably, this social structure exhibits a rise-and-fall behavior. A well pronounced quasi-periodic dynamics, which is closely associated with the dissipation of resources that are needed to sustain the social links, is revealed. (paper)

    This book systematically interprets and documents new, unifying principles and basic laws describing the most relevant aspects of hierarchy. To do so, it discusses recent experiments and models that are simple and realistic enough to reproduce the observations, and develops concepts for a better understanding of the complexity of systems consisting of many organisms. The book covers systems ranging from flocks of birds to groups of people.   Although it focuses on hierarchical collective behavior in general, two aspects pop up in the majority of cases: collective motion and dynamically changing, partially directed networks (and the natural relation between the two). In addition, it offers a brief description of the most relevant definitions and concepts involved in the context of hierarchies, presenting both a review of the current literature and a number of new experimental and computational results in more detail. It is a valuable resource for students and scholars pursuing research on the structure of in...

    2011-11-01

    The main purpose of this study is to fill a substantial knowledge gap regarding reaching a uniform group decision in English curriculum design and planning. A comprehensive content-based course criterion model extracted from existing literature and expert opinions was developed. Analytical hierarchy process (AHP) was used to identify the relative importance of course criteria for the purpose of tailoring an optimal one-week immersion English as a second language (ESL) curriculum for elementary school students in a suburban county of Taiwan. The hierarchy model and AHP analysis utilized in the present study will be useful for resolving several important multi-criteria decision-making issues in planning and evaluating ESL programs. This study also offers valuable insights and provides a basis for further research in customizing ESL curriculum models for different student populations with distinct learning needs, goals, and socioeconomic backgrounds.

    Full Text Available Lowering the string scale in the TeV region provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal dimensions, in the submillimeter region, and transverse to a braneworld where our universe must be confined. I review the main properties of this scenario and its experimental implications.

    In an attempt to resolve questions regarding the symptom classification of autism spectrum disorder (ASD), previous research generally aimed to demonstrate superiority of one model over another. Rather than adjudicating which model may be optimal, we propose an alternative approach that integrates competing models using Goldberg's bass-ackwards method, providing a comprehensive understanding of the underlying symptom structure of ASD. The study sample comprised 3,825 individuals, consecutive referrals to a university hospital developmental disabilities specialty clinic or a child psychiatry outpatient clinic. This study analyzed DSM-IV-referenced ASD symptom statements from parent and teacher versions of the Child and Adolescent Symptom Inventory-4R. A series of exploratory structural equation models was conducted in order to produce interpretable latent factors that account for multivariate covariance. Results indicated that ASD symptoms were structured into an interpretable hierarchy across multiple informants. This hierarchy includes five levels; key features of ASD bifurcate into different constructs with increasing specificity. This is the first study to examine an underlying structural hierarchy of ASD symptomatology using the bass-ackwards method. This hierarchy demonstrates how core features of ASD relate at differing levels of resolution, providing a model for conceptualizing ASD heterogeneity and a structure for integrating divergent theories of cognitive processes and behavioral features that define the disorder. These findings suggest that a more coherent and complete understanding of the structure of ASD symptoms may be reflected in a metastructure rather than at one level of resolution. © 2017 Association for Child and Adolescent Mental Health.

    Specialization and hierarchy are organizing principles for primate cortex, yet there is little direct evidence for how cortical areas are specialized in the temporal domain. We measured timescales of intrinsic fluctuations in spiking activity across areas and found a hierarchical ordering, with sensory and prefrontal areas exhibiting shorter and longer timescales, respectively. On the basis of our findings, we suggest that intrinsic timescales reflect areal specialization for task-relevant computations over multiple temporal ranges.

    1990-07-01

    The authors show that in a gauge theory with gauge hierarchy, a long-range attractive feeble force can arise in general within the framework of perturbative field theory. The force is the result of the existence of a Higgs boson whose mass and matter couplings are both naturally suppressed by powers of the hierarchical scale ratio. Some simple but realistic examples are used to demonstrate this mechanism.

  16. Affect in electoral politics.

    Science.gov (United States)

    Glaser, J; Salovey, P

    1998-01-01

    Recent U.S. history provides vivid illustrations of the importance of politicians' emotional displays in subsequent judgments of them. Yet, a review of empirical research on the role of affect (emotion, mood, and evaluation) in electoral politics reveals little work that has focused on the impact of candidates' emotional expression on voters' preferences for them. A theoretical framework is proposed to identify psychological mechanisms by which a target's displays of emotion influence judgments of that target. Findings from the emerging literature on emotions and politics challenge the traditional assumption of political science that voters make decisions based solely on the cold consideration of nonaffectively charged information. The affect and politics literature, although somewhat unfocused and broad, represents an interdisciplinary domain of study that contributes to the understanding of both electoral politics and social interaction more generally.

  18. The Politics of Dependence

    DEFF Research Database (Denmark)

    Cockburn, Patrick Joseph

    The central claim of this book is that thinking about ‘dependence’ should be at the core of political theory principally because it helps us to think about issues of economic justice. Unlike political theories that either condemn or celebrate dependence, the book argues that dependence...... is an inescapable fact of social life, neither good nor bad in itself. The real political issues are about how we as a society organise and judge various forms of dependence. And this is, in fact, what much political debate is about if we dig beneath the surface. On the one hand, we disagree about how we should...... organise vulnerability; on the other hand, we disagree about who we should condemn as parasitical. Vulnerability and parasitism are thus key concepts for understanding political debate about forms of dependence. Showing the tension between these two sides to the problem of economic dependence...

  19. Socrates: Platonic Political Ideal

    Directory of Open Access Journals (Sweden)

    Christopher P. Long

    2012-08-01

    Full Text Available This essay articulates the differences and suggests the similarities between the practices of Socratic political speaking and those of Platonic political writing. The essay delineates Socratic speaking and Platonic writing as both erotically oriented toward ideals capable of transforming the lives of individuals and their relationships with one another. Besides it shows that in the Protagoras the practices of Socratic political speaking are concerned less with Protagoras than with the individual young man, Hippocrates. In the Phaedo, this ideal of a Socrates is amplified in such a way that Platonic writing itself emerges as capable of doing with readers what Socratic speaking did with those he encountered. Socrates is the Platonic political ideal. The result is a picture of the transformative political power of Socratic speaking and Platonic writing both.

    Full Text Available Political violence plays a huge role in public affairs and people's behavior, requiring both knowledge and rigorous research in many of its occurrences and its consequences for the proper management, organization and functioning of a society as a whole. Although political violence is a problem of a particular importance in our social life it is not analyzed and investigated in the scientific literature. Political violence it is a subject that usually passes into oblivion. This study presents some ideas and themes about the role and functions of political power, displaying the types of political violence and their consequences for the management and functioning of a society, which can be subject to wider debates and researchs.
