Social Hierarchies (social + hierarchy)
Selected AbstractsNaked Mole-Rat is Sensitive to Social Hierarchy Encoded in Antiphonal VocalizationETHOLOGY, Issue 9 2009Shigeto Yosida The maintenance of social relationships is critical for group-dwelling species. Social animals often exhibit behaviors such as antiphonal vocalizations that reduce conflict and maintain affiliations. Naked mole-rats (Heterocephalus glaber) have a complex hierarchical society comparable to that of bees and ants. They are also known for their extensive vocal repertoire, which may have evolved in the absence of visual cues. The most frequent vocalization used by naked mole-rats is the soft chirp (SC). It has an antiphonal nature and may function in rank identification and in maintaining affiliations. Relative body weight differences, which are directly related to social rank, are positively correlated with SC emission rates. SCs are elicited from either physical touch or the SC of another conspecific, and other cues might contribute to SC utterance. In the current study, we examined whether an SC alone was able to elicit SC responses. Specifically, we presented artificial SC-like sounds and determined whether the response rate was modulated by the acoustic properties of the stimulus. An analysis of response latency revealed that animals responded to the audio stimuli, and a single audio stimulus could elicit responses from two animals. Thus, antiphony in naked mole-rats may occur among three or more animals. We also found that animals were able to discriminate the acoustic properties of the stimulus and responded more frequently to audio stimuli resembling SCs from large animals than to those resembling SCs from small animals. Therefore, naked mole-rats may be able to judge social relationships (dominant or subordinate) based solely on SCs. The constraints of subterranean habitats and increased social complexity may have led to the evolution of this communication system. [source] Interpopulation Variation in the Social Organization of Female Collared Lizards, Crotaphytus collarisETHOLOGY, Issue 11 2003Troy A. Baird We tested the hypotheses that levels of intrasexual aggression and the social structure among neighboring females differed in two central Oklahoma populations of collared lizards, Crotaphytus collaris, and examined the extent to which variation in aggression might be related to differences in the availability of arthropods, elevated perches used by females to scan for prey, and crawlspace refugia. Because both the costs of aggression and access to resources may influence female fitness, we also compared growth and survival rates and the number of clutches produced. At Morningside Farms Ranch (MS), lizards occupied naturally-formed sandstone washes with naturally-sculpted irregular topographies, whereas they inhabited homogenous fields of boulders used to construct flood control spillways at the Arcadia Lake Dam (AL). The frequency of intrasexual aggression was markedly higher at MS, and groups of MS females had social hierarchies structured by size and age with older females defending territories, whereas no such social structure was apparent at AL. Moreover, experimental removal of individuals from female groups resulted in more pronounced changes by the remaining females at MS than at AL. Elevated perches and crawlspace refugia were much less abundant at MS. Arthropod availability was similar at the two sites, but at AL arthropods were clustered near the edges of rock patches where elevated perches overlooking adjacent grassy areas were particularly abundant. MS females showed lower rates of survival, and growth during the first year (when growth is highest) than AL females, whereas the number of clutches produced by females at the two sites was similar. Our results suggest that variation in the availability of perch rocks may have resulted in differences in female social structure at the two sites, and relaxed intrasexual competition for perches may have resulted in higher female fitness at AL. [source] The introduction of social adaptation within evacuation modellingFIRE AND MATERIALS, Issue 4 2006S. Gwynne Abstract In recent history, a number of tragic events have borne a consistent message; the social structures that existed prior to and during the evacuation significantly affected the decisions made and the actions adopted by the evacuating population in response to the emergency. This type of influence over behaviour has long been neglected in the modelling community. This paper is an attempt to introduce some of these considerations into evacuation models and to demonstrate their impact. To represent this type of behaviour within evacuation models a mechanism to represent the membership and position within social hierarchies is established. In addition, individuals within the social groupings are given the capacity to communicate relevant pieces of data such as the need to evacuate,impacting the response time,and the location of viable exits,impacting route selection. Furthermore, the perception and response to this information is also affected by the social circumstances in which individuals find themselves. Copyright © 2005 John Wiley & Sons, Ltd. [source] Gendered Agendas: The Secrets Scholars Keep about Yorùbá-Atlantic ReligionGENDER & HISTORY, Issue 3 2003J. Lorand Matory Whereas scholars have often described the material interests served by any given social group's selective narration of history, this article catches scholars in the act of selectively narrating Yorùbá-Atlantic cultural history in the service of their own faraway activist projects. Anthropologist Ruth Landes' re-casting of the Afro-Brazilian Candomblá religion as an instance of primitive matriarchy not only encouraged feminists abroad but also led Brazilian nationalist power-brokers to marginalise the male, and often reputedly homosexual, priests who give the lie to Landes's interpretation. In the service of a longdistance Yorùbá nationalist agenda, sociologist Oyeronke Oyewumi has declared traditional Yorùbá society ,genderless', and found, among both North American feminist scholars and Yorùbá male scholars, allies in concealing the copious evidence of gender and gender inequality in Yorùbá cultural history. What these historical constructions lack in truth value they make up for in their power to mobilise new communities and alliances around the defence of a shared secret. The article addresses how politically tendentious scholarship on gender has inspired new social hierarchies and boundaries through the truths that some high-profile scholars have chosen to silence. [source] EXPANSION OF GOLF COURSES IN THE UNITED STATES,GEOGRAPHICAL REVIEW, Issue 1 2008DARRELL E. NAPTON ABSTRACT. Twenty-five million Americans play golf on the nation's 16,000 courses each year. These golf courses constitute a significant national landscape feature. Since 1878, when the game arrived in the United States, golf has filtered down the urban, economic, and social hierarchies to become accepted by and accessible to most Americans. During the ensuing thirteen decades the number, location, and layout of the nation's golf courses have responded to many of the same driving forces that impacted the nation, including decentralization, growth of the middle class, war, economic depression, suburbanization, and the increasing role of the federal government. Four epochs of golf-course growth and diffusion show the growing acceptance of the sport and depict where courses were most likely to be constructed as a result of the prevailing forces of each epoch. [source] Negotiating conflict within the constraints of social hierarchies in Korean American discourseJOURNAL OF SOCIOLINGUISTICS, Issue 3 2003M. Agnes Kang This paper provides an interactional account of conflict negotiation strategies in Korean American discourse. With specific attention to the sociolinguistic phenomenon of codeswitching among Korean Americans, I argue that speaking Korean at particular moments evokes ideologies of social hierarchy that serve to mitigate potential conflicts. The Korean social ideology of relative status has a major influence on how bilingual Korean Americans interact with one another, regardless of whether they are using Korean or English. The use of codeswitching, among other mitigating strategies in discourse, serves to instantiate these hierarchical relationships and introduces particular social norms that guide the observable actions used in navigating meaning and social relations. The data analyzed here show how the evocation of Korean social ideologies may serve as an identifiable characteristic of Korean American discourse. [source] Lawyer Satisfaction in the Process of Structuring Legal CareersLAW & SOCIETY REVIEW, Issue 1 2007Ronit Dinovitzer This article proposes a new approach to the study of job satisfaction in the legal profession. Drawing on a Bourdieusian understanding of the relationship between social class and dispositions, we argue that job satisfaction depends in part on social origins and the credentials related to these origins, with social hierarchies helping to define the expectations and possibilities that produce professional careers. Through this lens, job satisfaction is understood as a mechanism through which social and professional hierarchies are produced and reproduced. Relying on the first national data set on lawyer careers (including both survey data and in-depth interviews), we find that lawyers' social background, as reflected in the ranking of their law school, decreases career satisfaction and increases the odds of a job search for the most successful new lawyers. When combined with the interview data, we find that social class is an important component of a stratification system that tends to lead individuals into hierarchically arranged positions. [source] Governmentality and the Family: Neoliberal Choices and Emergent Kin Relations in Southern EthiopiaAMERICAN ANTHROPOLOGIST, Issue 1 2009JAMES ELLISON ABSTRACT, Rather than strictly local expressions of relatedness, kinship in southern Ethiopia has long been entangled with broad political and economic forces as people negotiate relations with each other, past generations, and the state. Accompanying government reforms in the 1990s, idioms of individualism and choice have circulated in transnational and national neoliberal discourses of development, rights, and economics. People in southern Ethiopia who use ideologies of ascribed social statuses to define local social hierarchies have employed these discourses in reshaping relatedness through an expansive trade association, which is referred to as a family and works through kinship principles of descent and generation. Drawing from recent scholarship on kinship and new reproductive technologies, I argue that, through mobile knowledges in neoliberal contexts, people choose this family and its lineage founder, transforming descent relations and land-based ideologies. These choices represent the workings of neoliberal governmentality in altering cultural relations of power and inequality.

LeCount Subtle differences in the context of feasting and manners of food consumption can point to underlying levels of civil and social competition in state-level societies. Haute cuisine and high styles of dining are characteristic of societies with fully developed civil and social hierarchies such as Renaissance Europe and the Postclassic Aztec. Competitive yet socially circumscribed political and social organizations such as the Classic lowland Maya may have prepared elaborate diacritical meals that marked status, but the nature of feasting remained essentially patriarchal. Ancient Maya feasting is recognizable through archaeologically discernible pottery vessel forms that were used to serve festival fare such as tamales and chocolate. Comparison of ceramic assemblages across civic and household contexts at the site of Xunantunich, Belize, demonstrates that drinking chocolate, more so than eating tamales, served as a symbolic cue that established the political significance of events among the Classic Maya.

Snodgrass In this article I examine Bhat myths and legends concerning kings and bards. Bhats are low-status praise-singers from the Indian state of Rajasthan. In exploring these tales, I examine my informants' ideas about an issue which has long been seen as a central conundrum of Indian caste theory: how best to characterize the status of those with priestly standing in relation to those classed as warriors and kings. In their stories, Bhats demonstrate the ways in which high-caste persons such as kings are utterly dependent on bardic services , thus rendering performers like themselves central, and kings peripheral. With respect to the debate about whether kings or priests rank first in South Asian schemes of rank and primacy, Bhats themselves think in terms of a third class of persons: bards. Further, I suggest that, in arguing for the social centrality of linguistically talented bards, my informants display a consciousness that is particularly attuned to the discursive construction of social hierarchies. Finally, I seek to explain why Bhats, who are bards of former untouchables now living in an ostensibly modern, casteless democracy, still speak so persistently of kings and royal bardship. My answer to this is that, in fabricating fictive royal bardic identities, present-day Bhats are able to appropriate roles and statuses now abandoned by the former elite bards of post-Independence Rajasthan. [source] PERSONIFICATIONS AND THE ANCIENT VIEWER: THE CASE OF THE HADRIANEUM ,NATIONS'ART HISTORY, Issue 1 2009JESSICA HUGHES This article represents an initial exploration of how allegorical figures were made and viewed in classical antiquity. It focuses on a well-known series of personifications which decorated a second-century ce temple complex in the heart of Rome. Previous studies of these sculpted reliefs have engaged in lively debate about which nations are represented, without ever reflecting on the processes by which the group has been designed and made. Here the individual personifications are replaced within the context of the group, and the fact that even the most cosmopolitan ancient viewer would have found the interpretation of these images problematic is demonstrated. This reading is shown to have wider implications, both for how the Roman world was conceptualized in and through these images, and for the construction of social hierarchies within the city of Rome itself. [source] The evolution of human fatness and susceptibility to obesity: an ethological approachBIOLOGICAL REVIEWS, Issue 2 2006Jonathan C. K. Wells ABSTRACT Human susceptibility to obesity is an unusual phenomenon amongst animals. An evolutionary analysis, identifying factors favouring the capacity for fat deposition, may aid in the development of preventive public health strategies. This article considers the proximate causes, ontogeny, fitness value and evolutionary history of human fat deposition. Proximate causes include diet composition, physical activity level, feeding behaviour, endocrine and genetic factors, psychological traits, and exposure to broader environmental factors. Fat deposition peaks during late gestation and early infancy, and again during adolescence in females. As in other species, human fat stores not only buffer malnutrition, but also regulate reproduction and immune function, and are subject to sexual selection. Nevertheless, our characteristic ontogenetic pattern of fat deposition, along with relatively high fatness in adulthood, contrasts with the phenotype of other mammals occupying the tropical savannah environment in which hominids evolved. The increased value of energy stores in our species can be attributed to factors increasing either uncertainty in energy availability, or vulnerability to that uncertainty. Early hominid evolution was characterised by adaptation to a more seasonal environment, when selection would have favoured general thriftiness. The evolution of the large expensive brain in the genus Homo then favoured increased energy stores in the reproducing female, and in the offspring in early life. More recently, the introduction of agriculture has had three significant effects: exposure to regular famine; adaptation to a variety of local niches favouring population-specific adaptations; and the development of social hierarchies which predispose to differential exposure to environmental pressures. Thus, humans have persistently encountered greater energy stress than that experienced by their closest living relatives during recent evolution. The capacity to accumulate fat has therefore been a major adaptive feature of our species, but is now increasingly maladaptive in the modern environment where fluctuations in energy supply have been minimised, and productivity is dependent on mechanisation rather than physical effort. Alterations to the obesogenic environment are predicted to play a key role in reducing the prevalence of obesity. [source] Dealing with Timing and Synchronization in Opportunities for Joint Activity ParticipationGEOGRAPHICAL ANALYSIS, Issue 3 2010Tijs Neutens The ability of people to access opportunities offered by the built environment is circumscribed by various sets of space,time constraints, including the requirements to meet other persons at particular times and places to undertake activities together. While models of space,time accessibility recognize that joint activities may constrain the performance of activities in space and time, their specifications do not explicitly acknowledge the opportunities that individuals of a group have for joint activity participation. Therefore, this article focuses on joint activity participation and argues that collective activity decisions are the outcome of a complex process involving various aspects of timing, synchronization, and social hierarchy. The utility-theoretic model proposed here quantifies the extent to which opportunities can be jointly accessed by a particular group of people within a specific time period. Central to the approach are three key variables: the attractiveness of an opportunity, the time available for activity participation, and the travel time to an activity location. Because of the multiperson character of joint activities, the determination of these variables is subject to individual preferences, privileges, and power differentials within a group. Specific attention is given to how time-of-day and synchronization effects influence the opportunities accessible to a group of individuals. The impact of these factors on joint accessibility is illustrated by a real-world example of an everyday rendezvous scenario. The outcomes of a simulation exercise suggest that time-of-day and synchronization effects significantly affect the benefits that can be gained from opportunities for joint activities. La capacidad de acceso a las oportunidades que los entornos construidos (como las ciudades) ofrecen a las personas, está limitada por un conjunto diverso de restricciones espacio-temporales. Entre ellas se incluyen los requisitos para coincidir y encontrarse con otras personas en determinados momentos y lugares con el fin de realizar actividades conjuntas. Los modelos de accesibilidad comunes reconocen que las actividades conjuntas pueden limitar el ejercicio de actividades en el espacio y el tiempo. Sin embargo, sus especificaciones no reconocen explícitamente las oportunidades disponibles a todos los individuos de un grupo para participar de una actividad conjunta. Es en este contexto y dadas las limitaciones descritas que este artículo se centra en la participación de individuos en actividades conjuntas y propone el argumento que la toma de decisiones relacionadas con dichas actividades son el resultado de un proceso complejo que involucra varios aspectos de temporización (programación temporal), sincronización, y jerarquía social. El modelo teórico de utilidad que se propone aquí cuantifica el grado en que las oportunidades pueden ser evaluadas en forma conjunta por un grupo de personas particular dentro de un período de tiempo específico. El marco general propuesto por los autores se basa en tres variables fundamentales: el atractivo de una oportunidad, el tiempo disponible para la participación de la actividad, y el tiempo de desplazamiento al lugar donde se lleva a cabo actividad. Debido al carácter particular de estas actividades (que involucran múltiples participantes), la determinación de estas variables está sujeta a preferencias individuales, a privilegios y a diferencias de poder dentro de un grupo. El presente estudio además presta atención especial a la forma en la que la hora del día y los efectos de sincronización pueden influenciar la disponibilidad de oportunidades para un grupo determinado de individuos. El impacto de estos factores sobre la accesibilidad agregada de actividades conjuntas es ejemplificado por los autores mediante un caso del mundo real que utiliza escenarios de encuentros diarios entre personas. Los resultados de este ejercicio de simulación sugieren que los efectos de la hora del día y la sincronización afectan significativamente los beneficios que se pueden obtener a partir las oportunidades disponibles para acceder a y realizar actividades conjuntas. [source] Osteobiography of a high-status burial from the lower Río Verde Valley of Oaxaca, MexicoINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 6 2008A. T. Mayes Abstract This paper presents the osteobiography of an individual from an early complex society who was clearly of "special" social status but was not classified a ruling elite. Our case derives from a unique burial found at the small site of Yugüe, located in the lower Río Verde valley on the Pacific coast of Oaxaca, Mexico. Burial 14-Individual 16 (B14-I16) dates to the late Terminal Formative Period (CE 100,250), an era of regional political centralization and concomitant social inequality. B14-I16 was interred with several valuable grave offerings. A plaster-backed pyrite mirror was found below his mandible, and his left hand held an elaborately incised flute made from a deer femur. The flute is the only object of its kind known for all of Terminal Formative Mesoamerica. Drawing on the physicality of inequality, we employ osteobiography to assess the social hierarchy. Although B14-I16 was clearly an individual of unusual status in the context of Yugüe, he was not immune from the biological assaults that affected people of less distinguished social position at this time. Like his contemporaries of all social statuses, he suffered ill health in the years during which he was weaned. However, a longer weaning period and access to additional resources may have positioned him to endure later illness better than others in this population. Passing the critical transition period at age 6 ½, a time when many children died in this burial site, his adolescent health was better than that of others in this population. Although B14-I16 did have adult responsibilities, he didn't engage in the kinds of physical labour that marked the skeletons of others. The placement of Burial B14-I16 in the middle tiers of the lower Río Verde valley's ancient social hierarchy provides insight into issues of inequality and status on an individual scale.

W. Rodgers The behavioural mechanisms and patterns of protandrous sex change in bluebanded gobies Lythrypnus dalli were investigated and compared to the well-described behaviour patterns of protogynous sex change. To do this, unisex groups of males and females were established; behavioural and anatomical changes were recorded over a 42 day period as social status and sexual phenotype were determined. In all cases, social status, rather than the expression of a particular behaviour, accurately predicted final sexual phenotype. Rates of submissive behaviour, but not aggressive behaviour, were predictive of each discrete status class. Multiple individuals changed sex simultaneously if their sexual phenotype and social status were discordant, a novel finding suggesting that once a social hierarchy is established, individuals determined their sexual phenotype, regardless of initial sex, based on a simple operational principle: if subordinate express female, if dominant or not subordinate express male. This work demonstrates that similar mechanisms underlie sex change in both directions in L. dalli and potentially other sex changing species. [source] Gender, Status, and LeadershipJOURNAL OF SOCIAL ISSUES, Issue 4 2001Cecilia L. Ridgeway More than a trait of individuals, gender is an institutionalized system of social practices. The gender system is deeply entwined with social hierarchy and leadership because gender stereotypes contain status beliefs that associate greater status worthiness and competence with men than women. This review uses expectation states theory to describe how gender status beliefs create a network of constraining expectations and interpersonal reactions that is a major cause of the "glass ceiling." In mixed-sex or gender-relevant contexts, gender status beliefs shape men's and women's assertiveness, the attention and evaluation their performances receive, ability attributed to them on the basis of performance, the influence they achieve, and the likelihood that they emerge as leaders. Gender status beliefs also create legitimacy reactions that penalize assertive women leaders for violating the expected status order and reduce their ability to gain complaince with directives.

[source] DEVELOPMENT OF DISPLAY BEHAVIOR IN YOUNG CAPTIVE BEARDED SEALSMARINE MAMMAL SCIENCE, Issue 4 2006Caroline E. Davies Abstract In this study of the ontogeny of vocal behavior in captive bearded seals, Erignathus barbatus, (three males and three females), only males exhibited vocal displays. The onset of display behavior coincided with sexual maturity. Males exhibited three types of dive displays associated with the performance of vocalizations. Vocalizing individuals were frequently attended by another male that maintained passive muzzle contact with the vocalizing male. These interactions were non-aggressive and might play a role in the establishment of a social hierarchy or they might allow the attendee to obtain "near-field" vocal information from the displaying male. Captive males' vocalizations resembled those of males in the wild. However, display dives were shorter, and fewer vocalization types were documented among the captive males compared to bearded seals in the wild. The capacity of the captive males for producing well-formed, long calls with large frequency changes was also significantly less than for wild males. These capacities will likely develop further as the males grow older. Individual capacity for vocal production appears to develop gradually, showing plasticity in form development over time. [source] Informal social status among coworkers and risk of work-related injury among nurse aides in long-term careAMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 5 2010Douglas J. Myers ScD Abstract Background A social network measure was used to explore whether one's rank in an informal social hierarchy of nurse aides employed in a single long-term care facility was associated with risk of work-related injury. Methods Six months of administrative staff schedule data and self-reported injury records were examined. Using survey data, social status rank in the informal hierarchy for each aide was operationalized as the number of coworkers who would approach the aide for advice about work-related matters. Conditional logistic regression was used to model the effect of social status on injury risk; cases were matched to controls consisting of coworkers present on the floor, shift, and date of the injury event. This allowed for a comparison of social status rank within social groups among workers with the same job title. Results Injury incidence rates decreased across tertiles of social status rank scores. A non-significant drop in injury risk in the highest tertile of social status was observed (adjusted OR,=,0.24 95% CI [0.05, 1.32]). Conclusion Findings of this exploratory study were internally consistent and support a theoretical framework suggesting that patterns of social relations between individuals based on informal social status in the workplace may contribute to differences in work-related injury risk among individuals with the same job title.

[source] Factors affecting fecal glucocorticoid levels in semi-free-ranging female mandrills (Mandrillus sphinx)AMERICAN JOURNAL OF PRIMATOLOGY, Issue 11 2008Joanna M Setchell Abstract Subordinate female cercopithecine primates often experience decreased reproductive success in comparison with high-ranking females, with a later age at sexual maturity and first reproduction and/or longer interbirth intervals. One explanation that has traditionally been advanced to explain this is high levels of chronic social stress in subordinates, resulting from agonistic and aggressive interactions and leading to higher basal levels of glucocorticoids. We assessed the relationships among fecal cortisol levels and reproductive condition, dominance rank, degree of social support, and fertility in female mandrills (Mandrillus sphinx) living in a semi-free-ranging colony in Franceville, Gabon. Lower-ranking females in this colony have a reproductive disadvantage relative to higher-ranking females, and we were interested in determining whether this relationship between dominance rank and reproductive success is mediated through stress hormones. We analyzed 340 fecal samples from 19 females, collected over a 14-month period. We found that pregnant females experienced higher fecal cortisol levels than cycling or lactating females. This is similar to results for other primate species and is likely owing to increased metabolic demands and interactions between the hypothalamus,pituitary,adrenal axis, estrogen, and placental production of corticotrophin releasing hormones during pregnancy. There was no influence of dominance rank on fecal cortisol levels, suggesting that subordinate females do not suffer chronic stress. This may be because female mandrills have a stable social hierarchy, with low levels of aggression and high social support. However, we found no relationship between matriline size, as a measure of social support, and fecal cortisol levels. Subordinates may be able to avoid aggression from dominants in the large enclosure or may react only transiently to specific aggressive events, rather than continuously expecting them. Finally, we found no relationship between fecal cortisol levels and fertility. There was no difference in fecal cortisol levels between conceptive and nonconceptive cycles, and no significant relationship between fecal cortisol level and either the length of postpartum amenorrhea or the number of cycles before conception. This suggests that the influence of dominance rank on female reproductive success in this population is not mediated through chronic stress in subordinate females, and that alternative explanations of the relationship between social rank and reproduction should be sought.

[source] The Expansion, Diversification, and Segmentation of Power in Late Prehispanic NascaARCHEOLOGICAL PAPERS OF THE AMERICAN ANTHROPOLOGICAL ASSOCIATION, Issue 1 2004Christina A. Conlee During the Late Intermediate Period (A.D. 1000,1476) the organization and foundation of power in Nasca was transformed from earlier times. Previously, religious resources were central to the development and maintenance of the political and social hierarchy. After the collapse of the Wari Empire and a period of balkanization, the resources used to establish and maintain power broadened considerably. The expansion of the power base into new realms coincided with an increase in the number of local elites in the drainage. There was no longer a focus on regional ceremonial centers; instead, elites were able to build power through a variety of activities including exchange, craft production (with a focus on utilitarian items), feasting, community-based ritual activities, and probably warfare and defense. During this period the levels of the political hierarchy grew and a more heterarchical type of regional polity developed. [source] | |||||||||||||||||||
