Historically and contemporarily the Black male experience has stimulated and provoked meaningful discussions in the realms of sport and academia. Black males are uniquely situated in American society, as they inhabit a liminal existence that oscillates between love and hate. Ladson-Billings (2011) expounds that Black boys are loved in the narrow niches of sport but are often abhorred in academic settings. The majority of research on the athletic and academic identities of Black student-athletes is conducted at the collegiate level in the revenue sports of basketball and football, and the research asserts that the collegiate sport atmosphere renders the two identities as mutually exclusive (Edwards, 1984; Harrison et al., 2011; Singer, 2008). There are studies occurring at the middle school level; however, these studies combine all male athletes into one group and do not distinguish the research participants according to their specific sport participation or racial background (Alfone, 2013; Fuller, Percy, & Bruening, 2013; Gorton, 2010). The few studies that distinguish between race and sport participation are somewhat dated (Mahiri, 1991, 1998; Nasir, 2000, 2008). This study addresses a gap in the literature by focusing solely on elite Black male middle school student-athletes to discover what leads to the seemingly incompatible athletic and academic identities that surface during college. I employed an instrumental case study grounded in Critical Race Theory which investigated and examined the experiences and perspectives of seven elite Black middle school club basketball players. Themes were generated by coding the interview data of all relevant stakeholders such as coaches, players, and parents as well as a thorough analysis of field notes, artifacts, and focus group data. Five themes emerged from the data, Academic Recognition, Athletic Recognition, Career, Racial Expectations, & Time Devoted to Sport and Intellectual Endeavors. This study is significant because it contextualizes the racial, athletic and academic climate of Black male athletes at a crucial time in their identity development. It contributes to the current literature by providing insight and furnishing essential information for parents, coaches and educators in order to bolster and enhance the academic identity and attainment of young Black male basketball players.

The purpose of this study is to determine appropriate choral literature for the adolescent male. Historically, scholars have focused on the lowering of the maturing male voice into the newly-formed chest register. During the change process, the male voice is unpredictable and can have a limited range. While a vast amount of repertoire for the adolescent male accommodates this downward progression and anticipates the narrow range, most adolescent boys are, in fact, capable of singing pitches above the chest register.Registers will be identified in this study. Discussion will pertain to registration shifts between chest register, head register, and falsetto in the adolescent male. I will investigate the use of the head register, which is a legitimate and vital component in healthy singing during adolescence. I will then compare registration to the historical knowledge of the male changing voice, which focuses mostly on the range and development of the newly-forming chest register.I will apply the concept of registration to choral repertoire taken from the 2005 and 2007 American Choral Directors Association (ACDA) national convention reading session packets. I will identify music that best and least facilitates the use and mixture of head-register and chest-register singing. Music for treble voices in various combinations (SA, SSA, SSAA, etc.) and three-part mixed music (SAB) will be examined. Each category presents a set of advantages and disadvantages for the adolescent male. Specific musical examples will illustrate the discussion. Careful repertoire selection with registration as a criterion is a key factor in unlocking male singing potential during adolescence. Although boys have unpredictable ranges, as it will be shown, registers are constant.

The level of juvenile hormone (JH) in several stages of larval development determines the characteristics of females. Diploid males and females of Melipona quadrifasciata that, in last instar larvae, received topical JH develop external morphological characteristics of queen. This work was based on morphometric data to investigate the effect of JH III in the development of haploid and diploid males of Melipona quadrifasciata and compare morphological characteristics of them with morphological characteristics already known in females of this species. Ten individuals were used for each treatment; workers, natural queens, queens produced from the topical application of JH, natural haploid males, haploid males received application of JH but did not differ, haploid males that received topical application of JH and developed features of queens (QLM - Queen-Like Male), natural diploid males, diploid males that received topical application of JH but did not differ and diploid QLM. The anatomical averages analyzed were: width of compound eyes, width of tibia, length of mouthparts, length of mandible, intertegule distance and interorbit distance. All averages allowed the separation of individuals into groups. However, the lengths of the mouthpart averages were differences most significantly between treatments. Natural queens and queens produced from the effect of JH had similar averages. Diploid and haploid QLM showed average variables with similar size in the natural queens and queens produced from topical application of JH. Workers were more similar to males than the queens in the most averages variables and, in general, the workers presented average size more than queens. Natural diploid and haploid males had close averages, which does not allow visual differentiation of these individuals. The dates confirm that the JH is primarily responsible for the differentiation of specific characteristics of each caste, and, in the high levels of it causes the appearance of the characteristics of queen, independent on genotype. / Abelhas do gênero Melipona possuem mecanismo de determinação das castas trofogenético. O nível de hormônio juvenil (HJ) em certas fases do desenvolvimento larval determina as características das fêmeas. Fêmeas e machos diplóides de Melipona quadrifasciata que, na fase pré defecante, recebem aplicação tópica de HJ desenvolvem características morfológicas externas de rainha. Este trabalho baseou-se em dados morfométricos para investigar o efeito do HJ III no desenvolvimento de machos haplóides e diplóides de Melipona quadrifasciata e comparar estes efeitos com os efeitos já conhecidos em fêmeas desta espécie. Foram utilizados dez indivíduos de cada tratamento, sendo operárias, rainhas naturais, rainhas produzidas a partir da aplicação tópica de HJ, machos haplóides naturais, machos haplóides que receberam aplicação de HJ mas não se diferenciaram, machos haplóides que receberam aplicação tópica de HJ e desenvolveram características de rainha (QLM – Queen-Like Male), machos diplóides naturais, machos diplóides que receberam aplicação tópica de HJ mas não se diferenciaram e QLM diplóides. As medidas anatômicas analizadas foram largura do olho composto, largura da tíbia, comprimento do aparelho bucal, comprimento da mandíbula, distância intertégula e distância interorbital. Todas as medidas possibilitaram a separação dos indivíduos em grupos, no entanto o comprimento do aparelho bucal foi a medida com diferenças mais significativas entre os tratamentos. Rainhas naturais e rainhas produzidas a partir do efeito do HJ possuem medidas semelhantes. QLM haplóides e diplóides apresentaram as variáveis medidas com tamanhos semelhantes as das rainhas naturais e produzidas a partir da aplicação tópica de HJ. Operárias se mostraram mais semelhantes aos machos do que as rainhas quanto a maior parte das maioria das variáveis medidas e, em geral, as operárias apresentam médias de tamanho maiores e as rainhas menores. Macho diplóides e haplóides naturais possuem medidas próximas, o que não permite a diferenciação visual desses indivíduos. Os dados corroboram que o HJ é o principal responsável pela diferenciação das características específicas de cada castas, assim, em altos níveis ele acarreta o aparecimento das características de rainha, independente do genótipo.

But with the onset of another crisis in the capital in mid-1970 and its bearing to the days progress, the social assistance has been recruited as the policy of the Brazilian social protection for "confrontation" and to "eradicate" the ills. This data is supported, especially when viewed as a process of that budget policy. In this sense, the objective of our work is to consider what both sides of that excess spotlight on social welfare policy, which has relied primarily on the riddle of the personifications of capital worldwide. To this end, we chose a critical-bibliographic and documentary that favored a cut of between three years (2005-2007) and socio-territorial space of Paraíba, specifically, the state management. From the theoretical and methodological nature of critical-dialectic, and the contribution of technical and operational physical and digital documents, especially, the Comptroller General of the State (CGE) and Court of the State (ECA), on public finances, mentioned that the back of high budget social assistance via "security income and nutritional security", is the cornerstone to increased degree of human barbarity that we sociometabólico this model of production, given its uninterrupted movement of accumulation and expansion in any compliance. / A sucção de uma fatia do trabalho excedente, sob forma de fundos públicos, os quais o Estado Moderno disponibiliza em suas mãos para administração dos ―males sociais‖ através da assistência social é um traço constitutivo no sistema do capital. Porém, com o desencadeamento de mais uma crise do capital, em meados da década de 1970 e seu rolamento até os dias em curso, a assistência social vem sendo recrutada como a política da proteção social brasileira para enfrentamento e até erradicação dos ―males sociais‖. Esse é um dado corroborado, sobretudo, quando analisada a processualidade orçamentária da referida política. Neste sentido, o objetivo precípuo do trabalho é analisar qual o verso desse excesso de holofotes na política de assistência social, que vem contando, sobretudo, com o crivo das personificações mundiais do capital. Para tanto, optamos por uma pesquisa critíco-bibliográfica e documental, que privilegiou um recorte temporal de três anos (2005-2007) e o espaço socioterritorial da Paraíba, de modo específico, a gestão estadual. A partir do referencial teórico-metodológico de cariz crítico-dialético, e do aporte técnico operativo de documentos físico-digitais, sobretudo, da Controladoria Geral do Estado (CGE) e Tribunal de Contas do Estado (TCE), sobre as finanças públicas, assinalamos que o verso da elevação orçamentária da assistência social, via ―segurança renda e segurança nutricional‖, tem como pedra angular a intensificação do grau de barbárie humana a que chegamos nesse modelo sociometabólico de produção, face seu movimento ininterrupto de acumulação e expansão sob qualquer condicionalidade.

We intent to glimpse in which measurement the forethoughts of this Brazilian thinker makes of Latin America; if it can be considered a project of identification of the Latin American identity and as such design incorporates the mestizo man as bearer. This present project in Bomfim s work is especially based on the ideas of social parasitism, miscegenation. As an unfoldment of the dissertation, we focused on an analysis of Bomfim s intellectual biography connected with the intellectual discourse of the time. This locates spatially and temporally the Brazilian and foreign interlocutors of Bomfim. In this sense, we identify the streamlines that explicit or implicitly influenced the construction of a distorted conception of Latin America and of the Latin-American and which are refuted in Bomfim s works. Such refutations are the basis for Bomfim s discourse because his narratives are of resistance and his thought is characterized by the defense, as well as attacks the neo-colonization pretensions of both Europe and the United States, regarding Latin America. Finally, the fundamental conceptions that bring Bomfim originality to this discussion were worked; it s specificity and importance, both for the Latin-American identity as for a possible national identity. Herein, in a macro micro relation, Bomfim thinks Latin America from a view point in Brazil. He accentuates the miscegenation, the cultural plasticity and education as the fundaments of his Latin-American identification project. / A presente dissertação objetiva contribuir para o debate latino-americanista trazendo para a discussão as idéias do pensador brasileiro chamado Manoel Bomfim (1868-1932) específicamente com relação à identidade latino-americana. Pretendemos, para tanto, vislumbrar em que medida as considerações que este pensador brasileiro faz acerca da América Latina podem ser consideradas como um projeto de identidade latino-americana, e como tal projeto incorpora o homem mestiço como seu portador. Tal projeto presente em Bomfim embasa-se principalmente nas idéias de parasitismo social e mestiçagem. Como desdobramento da dissertação, pontuamos uma análise da biografia intelectual de Bomfim concatenada com o discurso intelectual da época. Neste sentido, identificamos as correntes de pensamento que explícita ou implicitamente influenciaram a construção de uma visão deturpadora da América Latina e do homem latino-americano e que são refutadas nas obras de Bomfim. Tais refutações são basilares para o seu discurso, pois sua narrativa é uma narrativa de resistência e seu pensamento se caracterizará pela defesa das acusações de degeneraçao, ao mesmo tempo em que ataca as pretensões de neo-colonização da América Latina tanto da Europa quanto dos Estados Unidos. Por fim, trabalha-se as concepções fundamentais que trazem a originalidade de Bomfim para este debate, sua especificidade e importância, tanto para uma identidade latino-americana quanto para uma possível identidade nacional. Isto numa relação entre o macro e o micro, pois Bomfim pensa a América Latina a partir do Brasil. Salienta a mestiçagem, a plasticidade cultural e educação como fundamentos de seu projeto identitário latino-americano.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Infection by Trypanosoma evansi causes various pathological changes in animals, as well as reproductive problems whose pathogenesis is not fully known. Therefore, the objective of this study was to evaluate the serum concentrations of reproductive hormones, histopathology and biomarkers of oxidative stress in testicles of rats experimentally infected with T. evansi. Twenty four animals were divided in two groups with 12 animals each. Group A was formed by healthy Wistar rats (uninfected) and group B composed by animals infected with T. evansi. Both groups were divided into two subgroups (n=6) from which were collected serum and testicular fragments on day five and 15 post-infection. A significant reduction (P<0.01) in the levels of LH, FSH, testosterone and estradiol associated to the increase in cortisol levels was observed in serum of infected animals when compared to negative control. Also an increase in the concentrations of nitrite/nitrate (NOx), lipid peroxidation and protein oxidation was observed in the testicles. The histopathology showed testicular degeneration in the infected animals. Based on these results, we can conclude that infection with T. evansi may reduce the reproductive capacity of male and/or inducing infertility in rats, either directly or indirectly. / A infecção por Trypanosoma evansi causa diversas patologias em animais, assim como problemas reprodutivos cuja patogenia não está totalmente elucidada. Em virtude disso, o objetivo deste estudo foi avaliar a concentração sérica de hormônios reprodutivos, marcadores de estresse oxidativo e histopatologia de testículos de ratos infectados experimentalmente por T. evansi. Foram usados 24 ratos Wistar, divididos em dois grupos com 12 animais cada. O grupo A foi formado por roedores sadios e o grupo B por animais infectados com T. evansi. Estes grupos foram divididos em subgrupos (n=6) para coleta de amostras nos dias 5 (A1 e B1) e 15 pós-infecção. No soro, foi observado uma redução significativa (P<0.01) nos níveis de LH, FSH, testosterona e estradiol associado ao aumento nos níveis de cortisol nos animais infectados quando comparado ao controle negativo. Também foi verificado um aumento nas concentrações de nitrito/nitrato, peroxidação lipídica e oxidação proteica nos testículos, sugestivo de lesão celular, e que foi confirmada na histopatologia com observação de degeneração testicular nos roedores infectados. Com base nestes resultados, podemos concluir que a infecção por T. evansi pode reduzir a capacidade reprodutiva do macho e/ou causar infertilidade em ratos, de forma direta ou indireta.

The purposes of the study were to compare ratings of perceived exertion of aerobic dance and treadmill performances under equal work loads and to compare ratings of perceived exertion by males and females in aerobic dance and treadmill work. Subjects were twenty-six college men and women in co-educational conditioning classes. Heart rates were monitored after work bouts and perceived exertion was determined using Borg's RPE scale. Data were analyzed by a two-way analysis of variance with repeated measures. Conclusions of the investigation were: (1) aerobic dance is perceived as less strenuous than the treadmill under equal work loads, and (2) males and females perceive aerobic dance as less strenuous than the treadmill under equal energy bouts.

El presente trabajo de investigación busca sustentar el emprendimiento de un proyecto empresarial dentro del rubro cosmético basado en la elaboración de una crema facial dirigido al segmento masculino de los distritos top de Lima. La ventaja competitiva del producto radica en su componente principal, siendo la manteca del cacao blanco piurano, extraído de los valles de la zona norte del Perú, por sus cualidades antioxidantes, hidratantes y rejuvenecedoras. Esta idea de negocio surge por la necesidad de los varones, que al igual que las mujeres, cada día buscan verse mejor en el cuidado de su piel y por ello dentro de su presupuesto destinan una parte para el cuidado de su rostro. Asimismo, ante esta situación de pandemia que vivimos por el Covid-19, el reto es aún mayor ya que los efectos de la cuarentena han ocasionado estrés, alergias y resequedad de la piel en el rostro. La empresa está conformada por profesionales, cada uno especialista en su disciplina, que con sus conocimientos y pasión en lo que hacen lograrán que la empresa surja, se consolide y se mantenga en el tiempo haciendo uso responsable de los recursos y enfocándose en el cliente. En ese sentido, para el desarrollo del proyecto, y sobre todo para la comercialización y distribución del producto se necesita una inversión de S/.70,502 Soles, de los cuales se está solicitando un financiamiento bancario del 30% y 70% con capital propio. / This research work seeks to support the business project entrepreneurial in the cosmetic field based on the elaboration of a facial cream aimed at the male segment of the top districts of Lima. The competitive advantage of the product lies in its main component, being the white cocoa butter, wich is from Piura, extracted from the valleys of the north of Peru, for its antioxidant, moisturizing and rejuvenating qualities. This business idea arises from the need of men, who, like women, seek to see themselves better in the care of their skin every day and therefore, within their budget, they allocate a part for the care of their face. Likewise, in the face of this pandemic situation that we are experiencing due to Covid-19, the challenge is even bigger since the effects of the quarantine have caused stress, allergies, and dry skin on the face. The company is made up of professionals, each one specialized in their own discipline, who with their knowledge and passion, will ensure that the company emerges, consolidates and maintains itself over time, making responsible use of resources and focusing on the client. In this sense, for the development of our project, and especially for the commercialization and distribution of the product, an investment of.70,502 soles is required, of of 30% will be financed by an financial entity and the rest will be from company partners´ capital. / Trabajo de investigación

<p>Black men experience numerous systemic challenges in pursuit of their education, yet they also possess strength to achieve academic goals. The purpose of this autoethnographic study is to describe the meaning of my experiences at an undergraduate engineering program at a historically White institution to increase awareness of the ways that Black men experience undergraduate engineering programs at historically White institutions. The overarching research question is: How do I make meaning of the formative experiences along my engineering education journey at an historically White institution through the lens of African American Male Theory? To answer this question, I chose critical autoethnography because it enabled me to use my role as the researcher along with my own experiences as part of the topic and group of study. Through this methodology, I described my experiences through the lens of African American Male Theory, which was not available to me at the time the events were occurring. I analyzed personal memory data (e.g., poems, speeches, applications, resumes and interview transcripts) and my researcher journal to provide a thorough personal account of my collegiate experiences and relative perspectives on those experiences. The findings of this study provide an in-depth understanding of how I experienced an engineering program at an HWI in such a way that offers insights to better support Black men in engineering. As such, this study calls for holistic support for Black male students in engineering through interventions such as culturally relevant curriculum, narrative evaluation, standards of inclusion for classrooms, culturally competent counselors, and hiring minoritized faculty. Finally, this study appeals for more research to investigate how Black men experience freedom while pursuing their engineering degree at HWIs. </p>
