Impulsivity And Brain Organization In Childhood Suicide: An Adolescent Brain And Cognitive Development (Abcd) Study, Katherine Lopez

Arts & Sciences Electronic Theses and Dissertations

Rates of suicide have steadily increased across all age cohorts, revealing a particularly concerning rise in suicide among much younger age groups (10-15 years old). Recent efforts aimed at understanding suicide in youth have leveraged work from the adult literature to more pointedly examine candidate risk factors associated with childhood suicide. A noteworthy body of work has begun to clarify the role that impulsivity plays in elevating suicide risk among adults and adolescents, a critical link warranting further research in childhood suicide given the vast and well-documented changes occurring in self-control and brain maturity throughout development. Here, we examined a …

The Ontogeny Of Complex Tool Use Among Chimpanzees Of The Goualougo Triangle, Republic Of Congo, Stephanie L. Musgrave

Arts & Sciences Electronic Theses and Dissertations

Various factors are hypothesized to have contributed to the flourishing of technology during human evolution, including high-fidelity social learning, a propensity for prosocial helping, and sex differences in foraging tool use. In this research, we examined the role of these factors on the development of complex tool-using skills among wild chimpanzees (Pan troglodytes troglodytes) in the Goualougo Triangle, Republic of Congo. These apes exhibit among the most complex tool behaviors of any nonhuman animal, including the flexible use of multiple tool types and the manufacture of tools from specific raw materials, according to a particular design. Specifically, we drew upon …

Selection Or Socialization? A Propensity Score Matched Study Of Personality And Life Events, Emorie Beck

Arts & Sciences Electronic Theses and Dissertations

Across the lifespan, personality changes in normative ways, but the source of such change remains ambiguous. Life events may be one impetus of such change, but strong selection effects into such events makes it unclear whether such change is driven by already existing differences (selection) between people or socialization following life events. In a preregistered study, we test socialization and selection effects of the Big 5 and life events using a large (N = 19,627) representative sample of Germans and 12 life events (e.g. marriage, retirement) from the GSOEP. Using propensity score matching and Bayesian multilevel growth curve models, we …

Development Of Social Exclusion Detection: Behavioral And Physiological Correlates, Hyesung Grace Hwang

Arts & Sciences Electronic Theses and Dissertations

The present work aimed to directly test the theoretical claims about how we as human detect social exclusion using both physiological and behavioral methods across different life stages. Because feeling excluded from a group is a common human experience that starts in early childhood, this basic human need to belong or connect with others is argued to be universal and thought to have an evolutionary basis. In fact, it has been argued that the ability to detect being excluded may be present from birth and detecting exclusion occurs rapidly with little cognitive processing. Study 1 tested whether this rapid detection …

“There Is No Care Here”: The Conflictual Ethics Of Kin And Bureaucratic Care In Botswana, Arielle Justine Wright

Arts & Sciences Electronic Theses and Dissertations

How do people make sense of “care” when it fails? My dissertation examines the ethical debates that are provoked by the limitations of care in the setting of home-based care and associated safety net programs in Botswana. The organization of care is negotiated across domestic and public domains, often incorporating concerns about kinship ties, dependency, and labor in the welfare state. Based on 16 months of ethnographic research, I demonstrate that the ethical evaluation of care varies between differently-positioned stakeholders engaged in providing chronic care. Economic conditions and socio-political ideologies shape the ethics of care by way of setting the …

Developmental Trajectories Of Executive And Verbal Processes In Children With Phenylketonuria, Zoe Hawks

Arts & Sciences Electronic Theses and Dissertations

Phenylketonuria (PKU) is a recessive disorder characterized by disruption in the metabolism of the amino acid phenylalanine. Using a verbal fluency task, previous studies demonstrated that word production is reduced in individuals with PKU relative to controls. Beyond word production, verbal fluency output can be scored for clustering and switching, which enable characterization of verbal and executive processes, respectively. The present study is the first to evaluate clustering and switching in PKU within a longitudinal design, thereby elucidating the developmental time course of core cognitive processes. To this end, semantic (animals, food/drink) and phonemic (S words, F words) fluency data …

Development And Validation Of The 34-Item Disability Screening Questionnaire (Dsq-34) For Use In Low And Middle Income Countries Epidemiological And Development Surveys, Jean-Francois Trani, Ganesh M. Babulal, Parul Bakhshi

Brown School Faculty Publications

Background: Although 80% of persons with disabilities live in low and middle-income countries, there is still a lack of comprehensive, cross-culturally validated tools to identify persons facing activity limitations and functioning difficulties in these settings. In absence of such a tool, disability estimates vary considerably according to the methodology used, and policies are based on unreliable estimates Methods and Findings: The Disability Screening Questionnaire composed of 27 items (DSQ-27) was initially designed by a group of international experts in survey development and disability in Afghanistan for a national survey. Items were selected based on major domains of activity limitations and …

Humanitarianism And The Anthropology Of Hunger, Kate Klein

Undergraduate Theses—Unrestricted

While the early view of hunger as the product of a world population too large to sustain has largely been eliminated, and the mainstream international community has come to accept that food insecurity results from issues of distribution rather than an insufficient global food supply, the emphasis on biotechnology in agriculture, humanitarianism in international aid, and social justice in international human rights law in the contemporary era has contributed to other barriers that prevent hunger alleviation.

In this thesis, I argue that these previous contemporary developments have had the capacity to hide hunger. My analysis of technology and humanitarian aid …

Growing Up Tamarin: Morphology, Reproduction, And Population Demography Of Sympatric Free-Ranging Saguinus Fuscicollis And S. Imperator, Mrinalini Watsa

All Theses and Dissertations (ETDs)

The Callitrichidae are family of small New World primates with a suite of distinctive morphological and behavioral adaptations that set them apart from other primates. Of primary interest is their reproductive system that includes compulsive twinning: ≥80% of births) and cooperative care of offspring by individuals other than biological parents: termed alloparenting). Further, hematopoietic tissues in callitrichids display signals of both self and sibling DNA, due to an exchange of stem cells early in gestation that renders twin callitrichids as cellular mosaics of each other. This phenomenon is known as genetic chimerism, which increases genetic relatedness between individuals and is …

Capabilities Perception Of Well-­‐Being And Development Effort: Some Evidence From Afghanistan, Jean-Francois Trani, Parul Bakhshi, Cécile Rolland

Brown School Faculty Publications

This paper examines the relationship between capabilities, well-being and the impact of development efforts in Afghanistan. Using data from a nationally representative survey, we argue that very vulnerable groups maintain a positive perception of well-being by referring to collective values and practices. Our data suggest that deprivation of individual basic capabilities does not systematically lead to a low perception of well-being if individuals have access to other capabilities such as love and care and participation in the community affairs. Nevertheless, access to basic capabilities remains crucial in order to ensure that social norms and expectations cease to constitute constraints and …
