Self-disclosure of mental illness in the college classroom: the role of stigma and avoidance

Many college students identify having a mental health condition, yet students may be ambivalent about self-disclosing their mental health. While stigma and self-disclosure have been examined in research, personal factors may also impact self-disclosure behaviors. The present study examined 150 U.S. college students with a self-identified mental health condition. Research aimed to predict classmate self-disclosure by stigma, avoidance beliefs, and the interaction of these variables. Multiple regression analysis found a significant interaction effect, whereby stigma was negatively associated with self-disclosure only under conditions of low avoidance. Implications suggest that self-disclosure interventions target stigma and avoidance beliefs to encourage greater self-disclosure

Qualitative Experiences of Rural Postpartum Women and Implications for Rural Social Work

Geographic barriers and shortages of healthcare professionals in rural America have been well documented. These barriers and shortages influence rural women’s access to maternity and associated healthcare services during pregnancy and mothers’ postpartum period, but their perspectives about these realities have been overlooked. Semi-structured interviews with 24 mothers residing in a rural North Dakota county were conducted to understand their perspectives about both accessing healthcare services and parenting children in a rural context, with emphasis on understanding these mothers’ experiences using non-rural maternity care. Thematic analysis of qualitative interview data led to the emergence of three core themes. First, mothers in the sample minimized geographic barriers they had to overcome to access healthcare despite describing significant travel and weather challenges. Second, mothers expressed concern over the lack of affordable and flexible childcare in their rural community. Finally, mothers described different experiences within rural and non-rural settings, noting specific advantages and disadvantages of each. Although our findings cannot be generalized to other rural mothers, local qualitative inquiry can inform and improve the competency of social work services within rural communities

The compositional analysis of hunter-gatherer pottery from the Kuril Islands

© 2016 Elsevier Ltd Archaeological analysis of pottery remains from Northeast Asia has traditionally emphasized macroscopic traits such as decoration and vessel form. While these features are important in characterizing the cultural affiliation of pottery, compositional analysis can provide new lines of evidence that highlight social processes such as migration and exchange. Using a ceramic assemblage recovered from the Kuril Islands of Northeast Asia, this research investigates the regional exchange of pottery associated with the Epi-Jomon and Okhotsk cultural traditions. Results of this study indicate cultural differences highly influence the geographic distribution of compositional groups and patterns of regional exchange.This research was funded by a Doctoral DissertationImprovement Grant from the National Science Foundation Division ofPolar Programs-Arctic Social Sciences (Award #1202879)

Economic Hardship, Social Support, and Maternal Depression: A Test of the Social Support Deterioration Model

Objective: Maternal depression in low-income women is a significant problem because of its negative consequences both to mothers and their children. Although the direct influence of economic problems on maternal depression has been previously noted, there is a more limited base of support that explains potential mechanisms that could explain this association. One theory suggests that economic difficulties could erode perceived social support; a model known as the "social support deterioration model". This research tests this social support deterioration model by examining the direct as well as indirect impact by which economic hardship is associated with depressive symptoms. Methods: A sample of 336 mothers with children in mental health treatment was analyzed. Structural equation modeling was used to examine the hypothesized paths depicted by the deterioration model and relevant demographic variables. Results: First, economic hardship positively predicted depressive symptoms. Second, economic hardship negatively predicted perceived social support. Third, social support negatively predicted depressive symptoms. Finally, social support was found to partially mediate the relationship between economic hardship and depressive symptoms. Being married and working outside the home were also found to have benefits to mothers. Conclusions: Low levels of perceived social support were found to be one mechanism that explains the elevated depressive symptoms of mothers who maintain high levels of economic hardship. Economic hardship also maintained a direct impact on maternal depressive symptoms in mothers with children in mental health treatment. Future research should consider social support and economic hardship as potential targets for prevention and intervention of maternal depression

Biogeography and adaptation in the Kuril Islands, Northeast Asia.

The Circumpolar North is generally recognized as a challenging environment to inhabit and yet, we know relatively little about how people managed their welfare in these places. Here, we add to the understanding of maritime hunter-gatherers in the subarctic North Pacific through a comparative approach that synthesizes biogeographic and archaeological data from the Kuril Islands. We conclude that our faunal, ceramic and lithic evidence support expectations from biogeography as assemblages from low biodiversity and insular regions show limited diet breadth, more locally produced pottery and a conservation of lithic resources. However, we highlight that these ecological factors did not strictly determine the occupation history of the archipelago as radiocarbon data suggests all regions experienced similar demographic fluctuations regard-less of their biogeography. These results imply additional pressures influenced the strategic use and settlement of the Kuril Islands and the need for increased chronological resolution to disentangle these complex historical factors

Evolution of the Okvik/Old Bering Sea culture of the Bering Strait as a major transition

Great transitions are thought to embody major shifts in locus of selection,labour diversification and communication systems. Such expectations arerelevant for biological and cultural systems as decades of research hasdemonstrated similar dynamics within the evolution of culture. The evolutionof the Neo-Inuit cultural tradition in the Bering Strait provides anideal context for examination of cultural transitions. The Okvik/OldBering Sea (Okvik/OBS) culture of Bering Strait is the first representativeof the Neo-Inuit tradition. Archaeological evidence drawn for settlementand subsistence data, technological traditions and mortuary contextssuggests that Okvik/OBS fits the definition of a major transition givenchange in the nature of group membership (from families to politicalgroups with social ranking), task organization (emergent labour specialization)and communication (advent of complex art forms conveying socialand ideological information). This permits us to develop a number of implications about the evolutionary process recognizing that transitions mayoccur on three scales: (1) ephemeral variants, as for example, simple technological entities; (2) integrated systems, spanning modular technology tosocio-economic strategies; and (3) simultaneous change across all scaleswith emergent properties.This article is part of the theme issue ‘Human socio-cultural evolution inlight of evolutionary transitions’

Geographical and social isolation drive the evolution of Austronesian languages.

The origins of linguistic diversity remain controversial. Studies disagree on whether group features such as population size or social structure accelerate or decelerate linguistic differentiation. While some analyses of between-group factors highlight the role of geographical isolation and reduced linguistic exchange in differentiation, others suggest that linguistic divergence is driven primarily by warfare among neighbouring groups and the use of language as marker of group identity. Here we provide the first integrated test of the effects of five historical sociodemographic and geographic variables on three measures of linguistic diversification among 50 Austronesian languages: rates of word gain, loss and overall lexical turnover. We control for their shared evolutionary histories through a time-calibrated phylogenetic sister-pairs approach. Results show that languages spoken in larger communities create new words at a faster pace. Within-group conflict promotes linguistic differentiation by increasing word loss, while warfare hinders linguistic differentiation by decreasing both rates of word gain and loss. Finally, we show that geographical isolation is a strong driver of lexical evolution mainly due to a considerable drift-driven acceleration in rates of word loss. We conclude that the motor of extreme linguistic diversity in Austronesia may have been the dispersal of populations across relatively isolated islands, favouring strong cultural ties amongst societies instead of warfare and cultural group marking

A quantitative workflow for modeling diversification in material culture.

Questions about the evolution of material culture are widespread in the humanities and social sciences. Statistical modeling of long-term changes in material culture is less common due to a lack of appropriate frameworks. Our goal is to close this gap and provide robust statistical methods for examining changes in the diversity of material culture. We provide an open-source and quantitative workflow for estimating rates of origination, extinction, and preservation, as well as identifying key shift points in the diversification histories of material culture. We demonstrate our approach using two distinct kinds of data: age ranges for the production of American car models, and radiocarbon dates associated with archaeological cultures of the European Neolithic. Our approach improves on existing frameworks by disentangling the relative contributions of origination and extinction to diversification. Our method also permits rigorous statistical testing of competing hypotheses to explain changes in diversity. Finally, we stress the value of a flexible approach that can be applied to data in various forms; this flexibility allows scholars to explore commonalities between forms of material culture and ask questions about the general properties of cultural change

Competition and extinction explain the evolution of diversity in American automobiles

One of the most remarkable aspects of our species is that while we show surprisingly little genetic diversity, we demonstrate astonishing amounts of cultural diversity. Perhaps most impressive is the diversity of our technologies, broadly defined as all the physical objects we produce and the skills we use to produce them. Despite considerable focus on the evolution of technology by social scientists and philosophers, there have been few attempts to systematically quantify technological diversity and therefore the dynamics of technological change remain poorly understood. Here we show a novel Bayesian model for examining technological diversification adopted from paleontological analysis of occurrence data. We use this framework to estimate the tempo of diversification in American car and truck models produced between 1896 and 2014 and to test the relative importance of competition and extrinsic factors in shaping changes in macroevolutionary rates. Our results identify a four-fold decrease in the origination and extinction rates of car models and a negative net diversification rate over the last thirty years. We also demonstrate that competition played a more significant role in car model diversification than either changes in oil prices or gross domestic product. Together our analyses provide a set of tools that can enhance current research on technological and cultural evolution by providing a flexible and quantitative framework for exploring the dynamics of diversification
