Camaraderie, mentorship, and manhood: Contemporary Indigenous identities among the A’uwẽ (Xavante) of Central Brazil

Rites of passage and associated social processes and configurations can foster a sense of shared purpose, fraternity, and dedication to community through common experiences of group trials and commitment. A’uwẽ (Xavante) age organization entails the social production of manhood through a privileged form of male camaraderie constructed through age sets and mentorship, rooted in the shared experience of rites of passage and coresidence in the pre-initiate boys’ house. This process is central to how A’uwẽ men understand themselves, their social relations with certain delineated segments of society, and their ethnic identity. It is a basic social configuration contributing to the maintenance of A’uwẽ social and ethnic belonging in contemporary times. Ethnography of lowland South America could benefit from expanding its reach to consider the contributions of age organization and ritualized camaraderie to social and ethnic identity because they comprise an additional dimension of social identity that does not fit neatly into previously emphasized orders of social relations for this geographical region

Response of Vegetation Important to Northern Bobwhites Following Chemical and Mechanical Treatments (Oral Abstract)

Populations of northern bobwhite (Colinus virginianus) have declined since the early 1900s due to large-scale land use changes and habitat destruction. In southern pine stands land managers have used a variety of treatments to control hardwood encroachment, a major contributing factor to the loss of optimal quail habitat. We compared the use of the herbicide Arsenal (imazapyr) and traditional mechanical treatments with and without fire to control hardwood stem encroachment on 2 study areas. On Tall Timbers Research Station, hardwood stem density decreased on herbicide and herbicide + burn plots, but increased on all mechanically treated plots between years. Herbicide and herbicide + burn plots resulted in a 3-fold increase in forb coverage between years, whereas mechanically treated plots did not increase forb coverage. On Foshalee Plantation, hardwood stem density decreased and forb coverage increased between years on chemically treated plots. A one-time application of Arsenal can control hardwood encroachment in pine forests and stimulate herbaceous species growth. Following treatment, vegetative communities likely can be maintained for prolonged periods by using traditional, less expensive, methods of management such as prescribed fire

Applications of advanced diffractive optical elements

Digital Optics Corporation is a UNC-Charlotte spin-off company, established to transfer technology developed at UNC-Charlotte for the design and manufacture Computer Generated Holograms (CGH's) and to market products based on CGH technology. DOC acquired core technologies from UNC-Charlotte including: (1) a CGH encoding process that can provide holograms with extremely high diffraction efficiency; (2) a low cost, high precision CGH manufacturing process; and (3) extensive holographic and refractive element design capabilities for design and evaluation of complex optical systems. These technologies have been used to design and/or manufacture optical components for a variety of applications including: (1) generation of Spot arrays; (2) fiber optic coupling elements; (3) optical interconnects between VLSI chips within and between multichip modules; and (4) imaging systems for head-mounted displays (HMD's)

Temporal analysis and contextual factors associated with HIV/AIDS in Brazil from 2000 to 2019

OBJECTIVE: To describe the profile of the HIV/AIDS epidemic in Brazil and its Federation Units by gender, identify its associated contextual factors, and track changes in its epidemiological pattern from 2000 to 2019. METHODS: T his i s a n e cological s tudy w ith e pidemiological d ata f rom D ATASUS a nd population data from the Brazilian Institute of Geography and Statistics. Time-series analyses of incidence rates by gender and trends were performed by joinpoint regressions, obtaining the average annual percent change (AAPC). Then, all genders were analyzed regarding the association between AAPC and the following contextual indicators: Municipal Human Development Index (HDI-M), Gini Index, Social Vulnerability Index, illiteracy rates, proportion of late diagnosis, and proportion of test distribution. RESULTS: Incidence rates in men showed a linear decreasing trend (AAPC = −0.6; 95%CI −1.1 to 0.0). Rates in women increased from 2000 to 2009 and decreased from 2010 to 2019, tending upward throughout the period (AAPC = 1.4; 95%CI 0.8 to 1.9). Analyses by gender ratio showed a downward trend (AAPC = −1.8; 95%CI −2.3 to −1.3), indicating a reduction in the rates in men when compared to women. Indicators and the AAPC showed an inverse association for all genders, in which the HDI-M was the variable with the most pronounced association, showing that higher human development indices are associated with lower variations in HIV/AIDS rates. CONCLUSION: Case distribution differ across genders, with an upward incidence trend in women and a possible association with gender-related vulnerabilities. It is important to think about public policies that consider these dimensions.OBJETIVO: Descrever o perfil da epidemia de HIV/aids no Brasil e nas unidades da federação de acordo com o sexo, identificar os fatores contextuais associados e acompanhar mudanças no padrão epidemiológico entre 2000 e 2019. MÉTODOS: Estudo ecológico utilizando dados epidemiológicos do Datasus, e populacionais do Instituto Brasileiro de Geografia e Estatística (IBGE). Inicialmente foram realizadas análises de séries temporais das taxas de incidência por sexo e de tendências por regressões joinpoint, com obtenção da média da variação percentual das taxas (average annual percent change – AAPC). Posteriormente procedeu-se a uma análise, para ambos os sexos, da associação da AAPC com os indicadores contextuais Índice de Desenvolvimento Humano Municipal (IDH-M), Índice de Gini, Índice de Vulnerabilidade Social, taxa de analfabetismo, proporção de diagnóstico tardio e proporção de distribuição de testes. RESULTADOS: Observa-se tendência linear de redução nas taxas de incidência para o sexo masculino (AAPC = -0,6; IC95% -1,1 a 0,0). Para o sexo feminino, houve aumento nas taxas entre 2000 e 2009 e declínio entre 2010 e 2019, com uma tendência de incremento no período completo (AAPC = 1,4; IC95% 0,8 a 1,9). As análises por razão entre os sexos indicaram tendência de declínio (AAPC = -1,8; IC95% -2,3 a -1,3), apontando redução nas taxas para o sexo masculino em relação ao sexo feminino. Verificou-se associação inversa dos indicadores com a AAPC para ambos os sexos, sendo IDH-M a variável com associação mais pronunciada, evidenciando que maiores índices de desenvolvimento humano estão associados a menores variações nas taxas de HIV/aids. CONCLUSÃO: Os casos se distribuem de formas distintas entre os sexos, com tendência de incremento na incidência em mulheres e possível associação com vulnerabilidades relacionadas ao gênero, sendo importante pensar em políticas públicas que considerem essas dimensões
