Viral Bodies: Uncontrollable Blackness in Popular Culture and Everyday Life

Viral Bodies: Uncontrollable Blackness in Popular Culture and Everyday Life maps rapidly circulated performances of Blackness across visual media that collapse Black bodies into ubiquitous “things.” Throughout my dissertation, I use viral performance to describe the uncontrollable discursive circulation of bodies, their behaviors, and the ideas around them. In particular, viral performance is employed to describe the complicated ways that (mis)understandings of Black bodies spread and are often transformed into common-sense beliefs. As viral performances, Black bodies are often made more visible, while simultaneously becoming more opaque. This dissertation examines the recurrence of viral performances of Blackness in viral videos online, film, and photography/images. I argue that viral performances make products that reinscribe stereotypical notions of Blackness while also generating paths of alterity—which contradict the normalized clichés and provide desirable possibilities for Black performance. Viral Bodies forges a new dialogue between visual and aural technologies, performance, and larger historic discourses that script Black bodies as visually (and sonically) deviant subjects. I am interested in how technologies complicate the re-presentation of images, ideas, and ideologies—producing a necessity for new decipherings of performances of Blackness in popular culture and everyday life.

The pre-reproductive period in a tropical bird: parental care, dispersal, survival, and avian life histories

The period between offspring birth and recruitment into the breeding population is considered one of the least understood components of animal life histories. Yet, examining this period is essential for studies of parental care, dispersal, demography, and life histories. Studies of the pre-reproductive period are particularly few in tropical regions, where the organization of life histories are predicted to differ compared to northern hemisphere species. For my dissertation I used radio-telemetry, mark-resighting, and field observations to study the pre-reproductive period in a Neotropical bird, the western slaty-antshrike (Thamnophilus atrinucha), in Panama. First, I found that parental care after offspring left the nest (the post-fledging period) was greater than care during the nestling period. Prolonged care resulted in a clear trade-off for parents as they did not nest again until fledglings from the first brood were independent. Parents fed offspring for a prolonged duration during the post-fledging period and higher post-fledging survival was observed compared to many northern hemisphere species. Second, I observed that offspring that remained with parents for longer periods on the natal territory had higher survival both while on the natal territory and after dispersal compared to those dispersing earlier. Parental aggression towards offspring increased with offspring age and offspring dispersed earlier when parents renested. Contrary to other family living species, only a small proportion of antshrike offspring remained on the natal territory until the following year and all dispersed to float. Floating is when juveniles wander within other breeding pairs’ territories. These results suggest that the benefits of delayed dispersal declined with offspring age and with renesting by parents. Third, I observed that survival during the dependent period and first year was greater in slaty antshrikes compared to that of northern hemisphere species. Pre-reproductive survival relative to adult survival was equal or greater than that observed in northern hemisphere species. The date offspring left the nest, mass, and age at dispersal influenced offspring survival, whereas offspring sex and year did not. Relatively high survival during the pre-reproductive period coupled with comparatively low annual productivity clarifies how many tropical species achieve replacement. High juvenile survival appears to obtain from extended post-fledging parental care, delayed dispersal, low costs of dispersal, and a less seasonal environment. Lastly, I experimentally manipulated begging at the nest to examine changes in parental behavior. Under elevated begging, parents increased provisioning rates and reduced the time between arrival to the nest and feeding of nestlings, potentially to reduce begging sounds. Furthermore, parents switched to preferentially feed the closest offspring during the begging treatment. This suggests parents either allowed sibling competition to influence feeding decisions, or feeding the closer nestling increased the efficiency of provisioning. In summary, I found that slaty antshrikes have delayed age at reproduction, higher post-fledging and first year survival, extended post-fledging parental care, equal or greater pre-reproductive survival relative to adult survival, and delayed dispersal compared to many northern hemisphere passerines. These results suggest that this tropical species has a strategy of high investment into few offspring. Furthermore, reproductive effort is equal or greater at least in slaty antshrikes compared to northern hemisphere species, suggesting that the latitudinal gradient in clutch size is not explained by a gradient in reproductive effort.

The Performance and Service Life Prediction of High Performance Concrete in Sulfate and Acidic Environments

Concrete substructures are often subjected to environmental deterioration, such as sulfate and acid attack, which leads to severe damage and causes structure degradation or even failure. In order to improve the durability of concrete, the High Performance Concrete (HPC) has become widely used by partially replacing cement with pozzolanic materials. However, HPC degradation mechanisms in sulfate and acidic environments are not completely understood. It is therefore important to evaluate the performance of the HPC in such conditions and predict concrete service life by establishing degradation models. This study began with a review of available environmental data in the State of Florida. A total of seven bridges have been inspected. Concrete cores were taken from these bridge piles and were subjected for microstructural analysis using Scanning Electron Microscope (SEM). Ettringite is found to be the products of sulfate attack in sulfate and acidic condition. In order to quantitatively analyze concrete deterioration level, an image processing program is designed using Matlab to obtain quantitative data. Crack percentage (Acrack/Asurface) is used to evaluate concrete deterioration. Thereafter, correlation analysis was performed to find the correlation between five related variables and concrete deterioration. Environmental sulfate concentration and bridge age were found to be positively correlated, while environmental pH level was found to be negatively correlated. Besides environmental conditions, concrete property factor was also included in the equation. It was derived from laboratory testing data. Experimental tests were carried out implementing accelerated expansion test under controlled environment. Specimens of eight different mix designs were prepared. The effect of pozzolanic replacement rate was taken into consideration in the empirical equation. And the empirical equation was validated with existing bridges. Results show that the proposed equations compared well with field test results with a maximum deviation of ± 20%. Two examples showing how to use the proposed equations are provided to guide the practical implementation. In conclusion, the proposed approach of relating microcracks to deterioration is a better method than existing diffusion and sorption models since sulfate attack cause cracking in concrete. Imaging technique provided in this study can also be used to quantitatively analyze concrete samples.

Parental unemployment and youth life satisfaction: The moderating roles of satisfaction with family life

Abstract While Europe is slowly recovering from the economic recession, its effects on labour markets are still visible. The number of jobless families has increased and previous research has shown that unemployment can affect the wellbeing of both parents and their children. In this study we explored the links between parental unemployment and youth life satisfaction by considering the potential moderating roles played by satisfaction with family life and perceived family wealth. We used descriptive statistics, correlations, simple moderation and moderated moderation models of regression on data from a representative sample of 3937 Portuguese students (Mage = 13.9 years; SD ± 1.7; 48 % boys). Results showed that the negative effects of parental unemployment on youth life satisfaction were moderated by youth perceived satisfaction with family life but not by perceived wealth. This suggested that during family unemployment, young people satisfied with their family life are less vulnerable to the negative effects of parental unemployment on their life satisfaction. The relationship between parental unemployment and youth well-being requires further research, especially during periods of labour market crisis.

Stress Concentration Factor and Fatigue Life Evaluation in offshore tubular KT-Joints

In the last few decades, offshore field has grown fast especially after the notable development of technologies, explorations of oil and gas in deep water and the high concern of offshore companies in renewable energy mainly Wind Energy. Fatigue damage was noticed as one of the main problems causing failure of offshore structures. The purpose of this research is to focus on the evaluation of Stress Concentration Factor and its influence on Fatigue Life for 2 tubular KT-Joints in offshore Jacket structure using different calculation methods. The work is done by using analytical calculations, mainly Efthymiou’s formulations, and numerical solutions, FEM analysis, using ABAQUS software. As for the analytical formulations, the calculations were done according to the geometrical parameters of each method using excel sheets. As for the numerical model, 2 different types of tubular KT-Joints are present where for each model 5 shell element type, 3 solid element type and 3 solid-with-weld element type models were built on ABAQUS. Meshing was assigned according to International Institute of Welding (IIW) recommendations, 5 types of mesh element, to evaluate the Hot-spot stresses. 23 different types of unitary loading conditions were assigned, 9 axial, 7 in-plane bending moment and 7 out-plane bending moment loads. The extraction of Hot-spot stresses and the evaluation of the Stress Concentration Factor were done using PYTHON scripting and MATLAB. Then, the fatigue damage evaluation for a critical KT tubular joint based on Simplified Fatigue Damage Rule and Local Approaches (Strain Damage Parameter and Stress Damage Parameter) methods were calculated according to the maximum Stress Concentration Factor conducted from DNV and FEA methods. In conclusion, this research helped us to compare different results of Stress Concentration Factor and Fatigue Life using different methods and provided us with a general overview about what to study next in the future.

La communauté musulmane en contexte migratoire et la réarticulation d’un « cosmos sacré » islamique : le cas de l’association Bel Agir de Montréal

Cette étude d’une association musulmane de Montréal explore, à travers le concept de communauté en sciences sociales, les dynamiques religieuses et sociales animant la vie des membres de l’association Bel Agir, où une enquête de terrain de plus de six mois a été effectuée. Composée en majorité d’anciens membres d’un mouvement islamiste non violent marocain et entièrement de migrants, l’association offre un espace où sont articulées les continuités et les discontinuités dans la vie religieuse et sociale de ses membres. Ainsi, notre mémoire examine en partie le rôle de la communauté religieuse dans le processus migratoire de ses membres. Par contre, notre analyse se focalise essentiellement sur le rôle de la participation des membres à la vie de la communauté dans les processus d’intériorisation de l’éthos religieux supporté par le groupe, et de réarticulation de ce même éthos dans la société québécoise. Ce faisant, nous explorons ce qui motive les membres à s’investir dans la communauté et à intégrer les enseignements du groupe dans leur vie individuelle.

TEOLOGIA E TRADIÇÃO NO CONTEXTO DAS RELIGIÕES DE UMBANDA: UMA ANÁLISE DO CONFLITO ENTRE CULTURA ACADÊMICA E POPULAR

A religião de Umbanda ocupa grande espaço na vida e no imaginário religioso brasileiro, e adota as lendas, mitos e folclore da cultura popular brasileira. Desprovida de texto sagrado, a Umbanda rejeita a ideia do entendimento de uma literatura sagrada como pressuposto para uma ligação com o divino, sendo mais preocupada com a experiência religiosa e do sagrado, como ponte entre a dimensão humana e divina. Embora de comum acordo sobre a importância da prática na religião de Umbanda, existe um forte debate teológico na questão do valor principal para as práticas e vida religiosa do filho de santo. De um lado, temos a Doutrina Esotérica que aposta na produção textual e teórica e, de outro, temos a Umbanda de popular, que aposta na experiência pessoal do filho de santo com a tradição oral e as práticas religiosas. De sua fundação até a presente data, a Umbanda Esotérica tem apostado na formação acadêmica como base principal para a instrumentalização do filho de santo para a prática no terreiro, assim como publicação de textos, livros, artigos, oferecimento de cursos e a criação da primeira instituição especializada de ensino, a Faculdade de Teologia Umbandista. Se por um lado, para alguns, isso possa parecer uma abertura para a modernização e melhor aceitação das práticas de origem africanas, para outros, representa uma limitação na prática e na experiência do filho de santo devido à racionalidade do espaço acadêmico. Desse modo, pretendo investigar esse conflito no discurso e nas suas especificidades, estudando literatura especializada e orgânica, tendo como eixo de investigação a seguinte questão: O que é mais importante para as práticas religiosas em Umbanda, a formação prática ou a acadêmica?

Representera och bli representerad : Elever med religiös positionering talar om skolans religionskunskapsundervisning

Hur kan lärare på bästa sätt möta elever med religiös positionering i religionskunskapsklassrummet?  Hur kan undervisningen utformas för att ge religiösa traditioner en framställning som elever med religiös positionering kan acceptera, relatera till och kanske också lära nytt av? Den här religionsdidaktiska studien handlar om hur elever som positionerar sig inom muslimsk, kristen, buddhistisk och judisk tradition talar om skolans religionskunskapsundervisning. Studien berör tre teman. För det första undersöks mötet mellan undervisningsinnehåll och elevernas erfarenheter av sin egen religiösa tradition och tro. För det andra riktas uppmärksamheten mot hur eleverna talar om sina erfarenheter av att vara eller att förväntas vara representant för sin egen tradition i undervisningen. Ett tredje tema handlar om hur eleverna beskriver ramar och förutsättningar för religionskunskapsundervisningen. Intervjumaterialet har analyserats med hjälp av kritisk diskursanalys. Resultaten visar bland annat att eleverna har svårt att känna igen och relatera till sin egen tradition i undervisningen. De befarar att undervisningen snarare förstärker än dekonstruerar stereotypa föreställningar om religion och religiöst liv. 

The Architecture of the Persian Period in the Levant

The earliest scholars were not concerned about preparing extensive investigations linking the Persian-period building remains excavated in the entire Levant together. Moreover, the research interests of scholars caused some impediments to the study of this period viz in the last decades; the Achaemenid period has been neglected by the scholars who -in turn- focused on the earlier and later periods for religious reasons. Too, while some regions have been studied abundantly, but it was not the case in other areas, which makes our knowledge is incomplete. From the explanation side, some scholars try to interpret the architectural remains from an ethnic perspective or unsubstantiated personal fancies, so their arguments were utterly lacking any objectivity. This thesis explores what are the Persian architectural and ornamental impacts on the Levantine architecture and the relations between Persian-period sites in Syria-Palestine region. Too, the architectural remains and their contents benefited us to clarify the settlement patterns in the regions being discussed. The author analyzed the ground plans of the buildings and their architectural features and ornamental motifs by conducting a descriptive, analytical, and interpretative study. He also conducted comparisons with similar buildings outside the Levant, especially in Fars to obtain a more comprehensive and systematic study, and then extracting any direct or indirect Persian influences. This has given us a better understanding of the nature of the social, political, and religious life in the entire Levant and the knowledge gap has been bridged to a satisfying extent. This study has demonstrated a few of the Achaemenid impacts, especially on the northern coastline of the Levant.

The Political and Artistic Program of Prince Petru Rares of Moldavia (1527-1538 and 1541-1546) and the Fresco Series Depicting the “Life of the Mother of God” in the Church of Humor Monastery

En 1993, l’église du monastère Humor et six autres églises du nord de la Moldavie (Roumanie) ont été classifiés comme patrimoine de l'UNESCO, en particulier en raison de leurs caractéristiques iconographiques et architecturales uniques. Construit au seizième siècle, le monastère Humor est devenu un riche centre religieux et culturel sous le patronage du prince Petru Rares de Moldavie. Ce centre a encouragé les innovations architecturales ecclésiales, ainsi qu’un programme très prolifique de fresques, extérieures et intérieures, exprimant une créativité au-delà du canon de la peinture de l'époque. La présente thèse est concentrée sur ces innovations architecturales et iconographiques, comprises à la lumière du contexte historique de ce moment unique dans l'histoire de la Moldavie, dans le siècle qui suivit la chute de Constantinople (1453). Tandis que la première partie de la thèse est concentrée sur ces circonstances historiques, et plus précisément sur l'impact du patronage du Prince Rares, la deuxième partie de la recherche est concentrée sur l'analyse des sources littéraires et de la théologie d’une série unique de fresques, placé dans la gropnita (chambre funéraire) de l’église monastique d’Humor, évoquant la vie de la Mère de Dieu. La série est un exemple extraordinaire d’interaction des textes, le Protévangile de Jacques et le Synaxarion, avec l'iconographie. Une attention particulière à l'iconographie du monastère Humor démontre le besoin de la corrélation entre texte et icône d'une part, ainsi que la nécessité d’une corrélation entre les études théologiques, l'art et l’histoire d’autre part. Un autre avantage de la recherche est de contribuer à une appréciation plus riche des trésors culturels et religieux des communautés chrétiennes de l'Europe de l'Est aux points de vue religieux et culturel, en réponse à leur reconnaissance comme patrimoine de l’UNESCO.

Natural selection and quantitative genetics of life-history traits in Western women: A twin study

Whether contemporary human populations are still evolving as a result of natural selection has been hotly debated. For natural selection to cause evolutionary change in a trait, variation in the trait must be correlated with fitness and be genetically heritable and there must be no genetic constraints to evolution. These conditions have rarely been tested in human populations. In this study, data from a large twin cohort were used to assess whether selection Will cause a change among women in contemporary Western population for three life-history traits: age at menarche, age at first reproduction, and age at menopause. We control for temporal variation in fecundity (the baby boom phenomenon) and differences between women in educational background and religious affiliation. University-educated women have 35% lower fitness than those with less than seven years education, and Roman Catholic women have about 20% higher fitness than those of other religions. Although these differences were significant, education and religion only accounted for 2% and 1% of variance in fitness, respectively. Using structural equation modeling, we reveal significant genetic influences for all three life-history traits, with heritability estimates of 0.50, 0.23, and 0.45, respectively. However, strong genetic covariation with reproductive fitness could only be demonstrated for age at first reproduction, with much weaker covariation for age at menopause and no significant covariation for age at menarche. Selection may, therefore, lead to the evolution of earlier age at first reproduction in this population. We also estimate substantial heritable variation in fitness itself, with approximately 39% of the variance attributable to additive genetic effects, the remainder consisting of unique environmental effects and small effects from education and religion. We discuss mechanisms that could be maintaining such a high heritability for fitness. Most likely is that selection is now acting on different traits from which it did in pre-industrial human populations.

Religious beliefs and practice, and alcohol use in Thai men

Buddhism, the Thai state religion, teaches that use of intoxicants should be avoided. Nonetheless, many Thai people drink alcohol, and a proportion are alcohol-dependent or hazardous or harmful drinkers. This study examines the relationship between Buddhist upbringing and beliefs and alcohol use disorders in Thai men. Three groups, comprising 144 non/infrequent/light drinkers, 77 hazardous/harmful drinkers and 91 alcohol dependents were inter-viewed regarding their early religious life and current religious practices and beliefs. No protective association was shown between early religious life and later alcohol use disorders, indeed, having lived as a buy in a temple for a period was commoner in those with adult alcohol problems. Few subjects reported frequent involvement in current religious activities (9, 8 and 6% in the non/infrequent/light drinkers, hazardous/harmful drinkers, and alcohol dependents respectively). Hazardous/harmful drinkers [odds ratio (OR) = 0.4, 95% confidence interval (0) = 0.2-0.9] and alcohol dependents (OR = 0.5, 95% Cl = 0.2-0.9) were less likely to report being moderately to strongly religious, than were non/infrequent/light drinkers, Understanding the association between religious beliefs and drinking behaviour can potentially assist in the development of prevention and treatment programmes.
