The purpose of this study was to identify the experiences, attitudes, and successes of a group of high achieving African American female students that impact their on-time high school graduation. On-time graduates are described as students who complete high school in four years. High achieving African-American female students completing high school on time identified factors related to family, school, and community as essential in their success. Several underlying factors are within the three themes that studies show can be used as a way to pilot programs, deter drop-outs from leaving school early, and cohesively work in communities across the United States. A qualitative approach was used to analyze a selected group of high achieving African American females' perceptions to their success in high school. The research questions were: 1. What school factors do a group of high achieving African-American female students perceive as attributing to their on-time graduation from high school with honors and advanced diplomas? 2. What family influences do these high achieving females perceive as attributes to graduating on-time with honors and advanced diplomas? 3. What community influences do these high achieving African American females' perceive as contributors to on-time graduation with honors and advanced diplomas? Twenty-four high achieving African American females' from one high school were eligible to participate in the study. Eight students participated in the study, which included open-ended interview questions and a sentence completion questionnaire. All interview questions were centered on the support provided by the school, community, or family. The results of the study showed parents; specifically the mothers of the participants had the greatest impact on the high achieving African American females' performance in high school. The teachers of the high achieving African American female students were supportive and caring. The community recognition that the high achieving African American females received was a motivating factor to varying degrees. The high achieving African American female participants, in the study, all possessed intrinsic motivation and work ethic to be academically successful. / Ed. D.

This thesis delves into the complex dynamics of female involvement in criminal gang environments. These females can be divided into two groups: insiders, who are introduced to the environment through close acquaintances, and outsiders, who do not have close relationships within the environment. Through qualitative interviews with key informants from Danish law enforcement and municipalities, this thesis addresses the females’ motivation to engage with gang members as well as the potential consequences of these relationships. This thesis also examines the challenges field professionals face when engaging with these females, as well as which preventive initiatives could be implemented in Western Copenhagen. The findings from this thesis revealed that females are motivated to engage in relationships with criminals due to various factors, encompassing the desire for status, protection, and financial or material gain. A potential consequence of these relationships is the risk of becoming a victim of either psychological, physical, or sexual abuse. Conversely, another potential consequence of such relationships is the pressure or temptation to participate in crime, thereby becoming an offender themselves. In certain cases, there will thus be a victim-offender overlap.There is a notable lack of attention towards females involved in gang environments in the preventive work in Western Copenhagen. Additionally, there is currently no unified approach when working with these females. As a result, professionals encounter various challenges when working with females involved with gang members. It is thus important to increase awareness about this issue and implement early preventive strategies tailored to females in Western Copenhagen. Finally, this thesis finds that when field professionals engage with these females, it is crucial to maintain a holistic approach, considering the diverse motivations and consequences the females encounter.

Fifty-nine female and six male little brown myotis (Myotis lucifugus) were radio-tagged during the summers of 2012, 2013, 2014, and 2015 in Yellowstone National Park. The grand models for daily maximum skin temperature (F98,154 = 1.55, P = 0.007), daily minimum skin temperature (F98,154 = 1.33, P = 0.05), and daily variation in skin temperature (F98,154 = 1.56, P = 0.006) were significant across roost type and reproductive condition class for adult females. Roosts were classified into Types A (warmest roosts), B (roosts with largest daily temperature variance), and C (stable and cool roosts) depending on differences in mean maximum, minimum, and variance in temperatures per day (P < 0.001). A total of 347 torpor bouts were recorded from 38 females across the 2012 to 2015 summer seasons. Bats across different reproductive classes and roost types used torpor at different hours of the day. My research suggests that adult female little brown myotis at high elevations in the Park extensively use and rely on building structures for roosting sites during the reproductive season, whereas males used primarily natural roosts.

The purpose of this study was to examine the degree to which several psychological and personality variables relate to anorexic and bulimic symptomatology in female undergraduates. Past research investigating the relationship between such variables and eating disorders has been contradictory for several reasons, including lack of theoretical bases, discrepant criteria, or combination of anorexia and bulimia nervosa. Recent investigators have concluded that it is important to examine subdiagnostic levels of eating pathology, especially within a college population. Thus, the present investigation used a female undergraduate sample in determining the extent to which several psychological factors--obsessiveness, dependency, over-controlled hostility, assertiveness, perceived control, and self-esteem--account for anorexic and bulimic symptomatology. Regression analyses revealed that anorexic symptoms were best explained by obsessiveness and then two measures of dependency, emotional reliance on another and autonomy. Bulimic symptoms were related most strongly to lack of social self-confidence (a dependency measure) and obsessiveness. Clinical implications and directions for future research are addressed.

Personality patterns of sexually abused female adolescent runaways are compared to personality patterns of physically abused female adolescent runaways. Eighty-six female adolescents from 13 to 17 years of age completed a self report inventory to determine personality traits. To test the hypotheses of the study, a multivariate analysis of variance was conducted, followed with univariate tests to find differences on separate dependent measures. Results indicated that on the Jesness Inventory there may be a common personality pattern associated with abuse. Univariate tests yielded data which indicated that although there may be a general personality pattern for abused adolescents, there were significant differences between the physically and sexually abused adolescents on some personality variables. Results were evaluated taking into account the selective sample from which the population was drawn. Recommendations for future research included the use of projectives, a more comprehensive personality inventory, and selected demographics.

The purposes of this study were (1) to determine if three selected aerobic dance related conditions would result in chronic alterations of flexibility of college women and (2) to compare flexibility measures of college age females during a semester of aerobic dance instruction. Subjects were sixty-three college women enrolled in aerobic dance, bowling, and archery classes. Eight flexibility measures were obtained during the third and eleventh weeks of the experimental period. Data were analyzed by a factor analysis the Pearson Product Moment Correlation, and eight oneway analyses of covariance. Conclusions of the investigation were (1) a program of aerobic dance alone is not sufficient to promote flexibility, and (2) supplemental flexibility activities of ten minutes duration used with aerobic dance training are beneficial in increasing hip flexion.

O trabalho busca contribuir com a compreensão da conservação dos quelônios da espécie Podocnemis expansa através de estudos de ecologia reprodutiva, avanço das fronteiras agropecuárias e do histórico de fiscalização, caça e comercialização desses animais na região central do Corredor Ecológico Araguaia Bananal no Estado do Tocantins. A pesquisa apresenta uma abordagem metodológica dividida em quarto etapas distintas. Inicialmente, busca apresentar e analisar as projeções da produção agropecuária dos municípios de Caseara, Cristalândia, Formoso do Araguaia, Lagoa da Confusão, Marianópolis e Pium com a quantidade de fêmeas de quelônios da espécie P. expansa nidificando nas praias do rio Javaés durante o período de execução do Projeto Quelônios da Amazônia (PQA), compreendido entre 1985 e 2010. Os dados da produção agropecuária foram analisados para a série histórica de 1990 a 2015, através do número de cabeças de gado de corte e área plantada com lavoura temporária e lavoura permanente, todos para o conjunto dos municípios citados. Para análise e previsão dos dados, utilizou-se o modelo de séries temporais Autorregressivo Integrado de Médias Móveis de Box Jenkins (1976). Em seguida, buscou-se avaliar o perfil socioambiental das pessoas que utilizam e/ou comercializam esses animais a partir dos laudos de apreensão e de entrevistas semiestruturadas. Ao todo foram registrados 93 autos de infração, com 589 animais recapturados e devolvidos a natureza, sendo que destes mais de 80% são da espécie P. expansa. Os infratores autuados nas ações de fiscalização se configuram essencialmente como pessoas de baixa renda, com pouca ou nenhuma escolaridade e idade variando entre 21 e 75 anos, todos do sexo masculino. Nas entrevistas, 88,34% afirmaram consumir os animais, sendo que 51,45% apresentaram preferência pela P. expansa, 30,09% pelo P. unifilis, 6,70% consomem Chelonoidis sp e apenas 11,76% não consomem, desse total, 60,19% afirmaram não consumir ovos. 61,16% afirmaram que o principal período de captura é de agosto a dezembro e que os índios são os principais responsáveis pela captura e comercialização, sendo apontados por 49,51% dos entrevistados. Para grande maioria, 67%, não existe fiscalização na região e que, mesmo sem a fiscalização, é razoável a quantidade de animais na natureza. Para 41,74%, o manejo sustentável através de cotas seria a melhor alternativa para preservação e conservação das espécies. Na terceira etapa, foram avaliados os aspectos geomorfológicos das áreas de nidificação da P. expansa entre 1985 e 2010 em cinco praias do rio Javaés na região central do Parque Nacional do Araguaia na Ilha do Bananal. A densidade dos ninhos ao longo das praias mostrou uma preferência desses animais por ambientes que possuem características geomorfológicas distintas, seja em relação às dimensões físicas, elevação do banco de areia ou variações no nível de água no rio. Na quarta e última etapa da pesquisa, buscou-se avaliar o padrão reprodutivo das fêmeas de P. expansa em ambiente natural. O tamanho das fêmeas foi estimado a partir dos rastros deixados por elas durante a deambulação e/ou logo após a postura. Os resultados mostram que fêmeas maiores possuem ninhadas com mais ovos, filhotes maiores e com maior massa corporal. / The work seeks to contribute to the understanding of the conservation of the species of Podocnemis expansa by means of studies on reproductive ecology, the advancement of agricultural frontiers and the control, hunting and commercialization of these animals in the central region of the Araguaia Bananal Ecological Corridor in the State of Tocantins. The research presents a methodological approach divided into four distinct stages. Initially, it seeks to present and analyze the projections of the agricultural production of the municipalities of Caseara, Cristalândia, Formoso do Araguaia, Confusion Lagoon, Marianópolis and Pium with the number of females of species of P. expansa species nesting on the beaches of the Javaés river during the period (PQA) between 1985 and 2010. The data of agricultural production were analyzed for the historical series from 1990 to 2015, through the number of heads of cattle and area planted with temporary crops and crops all the municipalities mentioned. For the data analysis and prediction, the Box-Jenkins (1976) SelfCorrelated Integrated Average Averages model was used. Next, the objective was to evaluate the socioenvironmental profile of the people who use and / or commercialize these animals from the seizure reports and semi-structured interviews. In all, 93 infraction notices were registered, with 589 animals recaptured and returned to nature, of which more than 80% belong to the species P. expansa. The offenders assessed in the actions of inspection are essentially as low-income people, with little or no schooling and age ranging from 21 to 75, all males. In the interviews, 88.34% reported consuming the animals, and 51.45% preferred P. expansa, 30.09% P. unifilis, 6.70% consumed Chelonoidis sp and only 11.76% did not consume, of this total, 60.19% stated that they did not consume eggs. 61.16% stated that the main capture period is from August to December and that the Indians are the main responsible for capture and commercialization, being pointed out by 49.51% of the interviewees. For the great majority, 67%, there is no inspection in the region and, even without inspection, the amount of animals in the wild is reasonable. For 41.74%, sustainable management through quotas would be the best alternative for the preservation and conservation of species. In the third stage, the geomorphological aspects of the expansa nesting areas between 1985 and 2010 were evaluated in five beaches of the Javaés river in the central region of the Araguaia National Park on Bananal Island. The density of the nests along the beaches showed a preference of these animals for environments that have distinct geomorphological characteristics, either in relation to the physical dimensions, elevation of the sandbank or variations in the level of water in the river. In the fourth and last stage of the research, the objective was to evaluate the reproductive pattern of P. expansa females in a natural environment. The size of the females was estimated from the traces left by them during ambulation and / or shortly after laying. The results show that larger females have litters with more eggs, larger pups and larger body mass.

ER have been reported in macrophages and in that sense, the estrogens modulate immune responses. Despite the sexual dimorphism of the immune responses in females and males is well established, there are few studies that elucidate the role of bioactive compounds such as genistein among the genders. We investigated the effects of genistein on mice macrophage functionality, benchmarking males and females, which are divided into three groups according to sex and stage of the estrous cycle. First we checked the cytotoxicity,employing the technique of MTT reduction, in the following compounds: genistein, quercetin and 17-estradiol in the presence or absence of lipopolysaccharide (LPS). And none of these altered cell viability. To test the functionality of macrophages, the cells were treated for 24 h with two concentrations of genistein and quercetin (5M and 10M) as well as two concentrations of 17-estradiol (0,01 and 10 M), besides the control of the vehicle, the dimethylsulfoxide (DMSO) at 0,5%. The macrophages’ funtion standarts determined by spectrophotometry were the NO production in both basal and LPS induced, the production of H2O2 induced by LPS and by light microscopy was evaluated the phagocytic ability of macrophages, which were challenged to phagocytize Zymosan particles opsonized or not, after two hours of treatments. The results show a inhibition percentage of basal NO production in macrophages treated with genistein 10M, 34% and 40% for males and females in diestrus, respectively. In the macrophages obtained from females in proestrus quercetin treatment alone (in lower and higher concentration) showed a decrease in basal NO production significantly compared to control, with inhibition of 24% and 34% respectively. As NO production induced by LPS, macrophages from males showed significant inhibition of production with all treatments (except quercetin 5 μM), while in females in diestrus, treatments genistein (5 and 10 μM) and quercetin (5 and 10 μM ), this parameter significantly decreased functional macrophages, with values corresponding respectively to 25%, 30%, 17% and 31%. Once in females in proestrus, basal NO production induced by LPS and was inhibited only by quercetin (10M). All treatments of macrophages collected from the male reduced the production of H2O2 and genistein inhibition percentage of 10M of 27%. In females in diestrus was observed that treatment with genistein 5 e 10 M and quercetin 10M inhibited respectively 29%, 32% and 37% the production of H2O2. The H2O2 production by macrophages from females in proestrus was significantly inhibited by all treatments (except estradiol 0,01 ηM and quercetin 10M), and the percentage inhibition of genistein 5 e 10M was 22%. The phagocytic activity of macrophages was not affected by treatment with genistein for either group. Our results suggest that NO production, macrophages premodulated by exposure to 17-estradiol, the effect of genistein is less pronounced, may possible be explained by downregulation of ER in ex vivo treatments. In conclusion we can infer that, the use of genistein should account for sex, and therefore variations in serum hormone concentrations of 17-estradiol (sexual cycle) in females. / A genisteína têm atividades estrogênicas, e pode se ligar aos receptores de estrogênio (RE), por isso é considerada um fitoestrógeno. RE têm sido relatados em macrófagos e nesse sentido, os estrogênios modulam as respostas imunes. Apesar do dimorfismo sexual das respostas imunes de fêmeas e machos estar bem estabelecido, existem poucos estudos que elucidem o papel de compostos bioativos como a genisteína entre os sexos. Neste estudo, investigamos os efeitos da genisteína na funcionalidade de macrófagos de ratos, avaliando comparativamente machos e fêmeas, sendo estes divididos em três grupos de acordo com o sexo e a fase do ciclo estral. Primeiramente verificamos a citotoxicidade, empregando a técnica de redução do MTT, dos seguintes compostos: genisteína, quercetina e 17-estradiol, na presença ou ausência de lipopolissacarídeo (LPS). E nenhum destes alterou a viabilidade celular. Para o ensaio da funcionalidade dos macrófagos, as células foram tratadas por 24 horas com duas concentrações de genisteína e quercetina (5M e 10M), como também duas concentrações de 17-estradiol (0,01 e 10 M), além do controle do veículo, o dimetilsulfoxido (DMSO) na concentração de 0,5%. Dos parâmetros de funcionalidade dos macrófagos, foram determinadas por espectrofotometria a produção de NO tanto basal quanto a induzida por LPS, bem como a produção de H2O2 induzida por LPS, e por microscopia de luz realizou-se a avaliação da capacidade fagocítica dos macrófagos, que foram desafiados a fagocitar partículas de Zimosan opsonizadas ou não, após tratamentos de 2 horas. Os resultados encontrados revelam uma porcentagem de inibição da produção de NO basal de macrófagos tratados com genisteína 10 M de 34% e 40%, para machos e fêmeas em diestro, respectivamente. Nos macrófagos obtidos das fêmeas em proestro apenas o tratamento quercetina (em menor e maior concentração) apresentou diminuição na produção de NO basal significativa em relação ao controle, com inibição de 24% e 34% respectivamente. Quanto a produção de NO induzida por LPS, macrófagos de machos apresentaram inibição significativa da produção com todos os tratamentos (exceto quercetina 5M), enquanto nas fêmeas em diestro, os tratamentos genisteína (5 e 10 M) e quercetina (5 e 10 M), diminuíram significativamente esse parâmetro funcional de macrófagos, com os valores correspondentes respectivamente a 25%, 30%, 17% e 31%. Já nas fêmeas em proestro, a produção de NO basal e induzida por LPS foi apenas inibida pela quercetina (10M). Todos os tratamentos dos macrófagos obtidos de machos reduziram a produção de H2O2, sendo porcentagem de inibição da genisteína 10 μM de 27%. Nas fêmeas em diestro observa-se que os tratamentos com genisteína 5 e 10M e quercetina 10 M inibiram respectivamente em 29%, 32% e 37% a produção de H2O2. A produção de H2O2 pelos macrófagos das fêmeas em proestro foi inibida significativamente por todos os tratamentos (exceto estradiol 0,01 M e quercetina 10 M), sendo que a porcentagem de inibição da genisteína 5 e 10 M foi de 22%. A atividade fagocítica dos macrófagos não foi influenciada pelo tratamento com a genisteína para nenhum dos grupos. Nossos resultados são sugestivos de que a produção de NO nos macrófagos prémodulados pela exposição ao hormônio estradiol o efeito da genisteína é menos acentuado, podendo ser explicado por possível downregulation dos RE em tratamentos ex vivo. Em conclusão podemos inferir que para o emprego da genisteína deve se levar em consideração o sexo, e por conseguinte, a variação da concentração hormonal sérica de 17-estradiol (ciclo sexual) em fêmeas.

I Österdalälven har mängden Siljansöring (Salmo trutta) minskat avsevärt på grund av kraftverk som stoppar fiskens vandringsvägar. För att lyckas med att stärka beståndet krävs en fördjupad kunskap kring fiskens beteendemönster, bland annat rörelser i samband med uppströms lekvandring. Denna studie är ett försök att ge en överblick av den lekmogna Siljansöringens uppströmsvandring i Österdalälven och se om det föreligger några skillnader mellan odlad/vild öring respektive hanar/honor. Genom akustisk telemetri har 18 Siljanöringars rörelser längs en begränsad älvsträcka registrerats under 56 dagar. Analys har gjorts för hitta variationer både rumsligt och tidsmässigt samt mellan odlade/vilda Siljansöringar respektive honor/hanar, likväl som skillnader avseende rörelser, tim- och dygnsaktivitet och benägenhet att söka sig uppströms till det definitiva vandringshindret Spjutmo kraftverk. Siljansöringarna rörde sig mer under dagen jämfört med natt vilket skulle kunna kopplas till påverkan från elproduktion och vattenströmmar som skapas vid Spjutmo kraftverks turbinutlopp och/eller att dagsljuset är en fördel då de använder sig av synintryck för att kunna navigera. Skillnader (dock ej statistiskt säkerställda) kunde urskiljas mellan odlade och vilda fiskar och hanar/honor, såsom exempelvis att vild fisk simmade längre sträckor än odlad. Studier som denna är viktiga för att kunna få en helhetsbild kring livsvillkor och beteendemönster för Siljansöring och därigenom lyckas med framtida förvaltnings- och åtgärdsarbeten. / The number of Siljan trout (Salmo trutta) in the River Österdalälven has declined due to hydropower development. To restore the river information about the behavioural patterns of the trout, such as upstream migration, are needed. The aim of this study is to describe the upstream movements of tagged Siljan trout as well as to identify differences between hatchery-reared and wild trout and between males and females. During 56 days, 18 individuals tagged with acoustic telemetry transmitters were registered in a section of the River Österdalälven. The data were analysed to identify variation in time and space as well as differences between origin (hatchery-reared vs wild trout) and sex. Analyses were also performed on hourly and diel movement patterns and if the fish swam upstream to the first migration barrier, the power station in Spjutmo. Variation in diurnal activity was identified, with higher activity during daytime compared to night, which might be related to power production in relation to currents flowing from turbine outlets and/or the importance of daylight for effective navigation. There were no significant differences identified between hatchery-reared and wild trout, respectively, nor were there any sex-related differences. Information obtained from this study is important to understand the situation for Siljan trout, to help in future management and restoration of this valuable stock of trout.

O objetivo deste estudo foi avaliar os parâmetros reprodutivos e os níveis séricos de marcadores metabólicos em fêmeas suínas suplementadas com ômega-3. Neste estudo, 463 fêmeas suínas foram suplementadas na dieta com uma fonte de DHA extraído de microalgas, a partir de 85 dias de gestação e durante a lactação e o intervalo desmame-estro (IDE). Os níveis de inclusão de DHA foram: 0,0 (controle); 3,5; 7,0; 14,0; e 28,0 g/d. Foram realizadas três coletas de sangue, no início do tratamento (durante a gestação), dez dias após o parto (durante a lactação) e um dia antes do desmame, para avaliação dos níveis séricos de indicadores metabólicos: triglicerídeos; colesterol; fator de crescimento semelhante a insulina tipo I (IGF-1); e ácidos graxos não esterificados (NEFA). Os tratamentos não apresentaram efeitos sobre a taxa de natimortalidade, o tamanho total da leitegada e a duração do IDE no parto no qual houve suplementação (P > 0,05), nem sobre o total de leitões nascidos e a taxa de natimortalidade no parto subsequente P > 0,05). Durante a gestação, os níveis séricos de colesterol e IGF-1 foram inferiores (P < 0,05) e os níveis de NEFA foram mais elevados durante a gestação (P < 0,05) do que durante a lactação e o IDE. Ainda, durante a gestação, os níveis séricos de triglicerideos foram reduzidos (P < 0,05) apenas em fêmeas suplementadas com 14 e 28 g de ômega-3. A suplementação de fêmeas suínas com esta fonte de ômega-3 não trouxe benefício para os parâmetros reprodutivos avaliados, possivelmente em função do ótimo desempenho observado durante o período do experimento. / Supplementation of diets of swine females with polyunsaturated fatty acids (PUFA) containing omega-3, especially the docosahexaenoic acid (DHA) may be an alternative to improve their reproductive performance. The objective of this study was to evaluate reproductive performance and serum levels of metabolic marker in swine females supplemented with omega-3. In this study, 463 swine females were supplemented in the diet with a source of DHA extracted from microalgae, from the 85th day of gestation and during both the lactation and the weaning-to-estrus interval (WEI). The DHA was included in the diet at: 3.5; 7.0; 14.0; and 28.0 g/d. Blood samples were collected at the beginning of the supplementation (during gestation), ten days after farrowing (during lactation) and one day prior to weaning, for determination of serum levels of metabolic markers: triglycerides; cholesterol; insulinlike growth factor type I (IGF-I); and non-esterified fatty acids (NEFA). No effect of the treatments was observed on the stillborn rate, total litter size and WEI at the parity in which supplementation occurred (P > 0.05), and also no effect occurred on total litter size and stillborn rate at the subsequent parity (P > 0.05). During the gestation, serum levels of cholesterol and IGF-I were lower (P < 0.05) and NEFA serum levels were greater than during lactation and the WEI (P < 0.05). Also during gestation, serum triglyceride levels were reduced (P < 0.05) only for females supplemented with 14.0 and 28.0 g of omega-3. The supplementation with DHA did not benefit the evaluated reproductive parameters of swine females, possibly due to the excellent performance observed during the experimental period.
