Strategies for decreasing sexually transmitted infections in adolescent females

Howard, Stacy F. 01 January 2010 (has links)
Sexually transmitted infections (STIs) are a common health problem in all populations; however, female adolescents are at increased risk for acquiring STIs and their complications. Their increased risk of acquiring STIs is due to their behavior, anatomy. and lack of knowledge about STIs. STIs have many complications in women. Some complications include: pelvic inflammatory disease, ectopic pregnancy, chronic pelvic pain, and infertility. The purpose of this integrative review is to identify current sexual behaviors of female adolescents, and to find strategies at preventing or reducing STIs within this population. Nurses and other health care providers need to know the current statistics of STIs in adolescent females, and need to understand their current sexual behaviors in order to implement effective preventative strategies.

An Analysis of Changes in Perceptions of Certified Athletic Trainers from 1996 to 2006 on the Women in Athletic Training Survey

Dieringer, Katherine I. 05 1900 (has links)
This study investigates how perceptions vary in athletic trainers regarding issues pertaining to women in the profession. Subjects included 1500 male and 1500 female certified athletic trainers who responded to 44 demographic and perceptions survey items used to determine whether perceptions were different based on the respondent's gender. Results were compared to a previously disseminated survey in 1996 to also determine if perceptions had changed from 10 years earlier. Results regarding the presentation of awards and the attainment of leadership positions in the organization were also compared to actual data collected. The data suggested that males perceptions had not changed, but females' perceptions had changed, in that females perceived that opportunities had improved. Data regarding the number of females who had ascended to leadership positions or had received awards did not support these perceptions, however, and female athletic trainers continue to struggle to obtain equality in both of these areas. Additionally, homosocial reproduction continues to influence the decreased number of women who are hired into various jobs, or advance into leadership positions, maintaining patriarchy in the athletics arena and in the athletic training organizations. Results suggested that because athletic training has been dominated by men since its inception, patriarchy continues to influence the lack of ascension of women into leadership positions and awards recognition. Many women are choosing to leave the profession due to the gender role pressure that they can not sustain a career in athletic training and raise a family. Men's professional sports continue to reject the concept of hiring women to serve as athletic trainers with their athletes, which also continues to preserve a patriarchal environment.

The Relationship of Assertiveness and Bulimia to Psychological Separation

O'Loughlin, Mary Ann, 1957- 08 1900 (has links)
The purpose of this study was to examine how parental separation is related to eating disturbances and assertiveness in females who struggle with bulimic symptoms. Two-hundred ninety-two undergraduate females from the University of North Texas comprised the subject group. Using pen and paper measures of assertiveness, bulimia, and parental separation, support was found for the prediction that there would be a relationship between assertiveness and parental separation. Likewise, partial support was found for the prediction that there would be a relationship between bulimia and parental separation. Parental separation was found to affect levels of bulimia and assertiveness. Finally, it was found that subjects endorsed greater emotional independence from fathers than from mothers.

Racial Differences in Female Achievement Motivation and Motivation to Work

Bruner, Yolanda Kaye 12 1900 (has links)
In the present project racial differences in female achievement motivation and motivation to work were examined, and related this information to the theory that African American females, when compared to White females, are less likely to marry someone equal to themselves in the areas of education, employment, and earning potential because of an assumed shortage of suitable African-American males. It was hypothesized that African-American females would score higher on assessments of achievement motivation and motivation to work, and rate lower the likelihood of meeting and marrying a partner equal in education level, employment level, and earning potential than would White females. Data analysis supported all hypotheses. The results were discussed in the context of the female achievement motivation literature as well as the literature concerning female motivation to work.

Sonhando acordada: um estudo sobre as práticas de leitura da coleção de romances clássicos históricos / Daydreaming: a study about the clássicos históricos novel collection´s reading practices

Amparo, Patrícia Aparecida do 25 April 2012 (has links)
Essa dissertação, parte dos estudos alocados na linha de pesquisa Historia e Historiografia da Educação, tem como objetivo compreender as práticas de leitura mantidas por leitoras de romances sentimentais, particularmente, a coleção de romances Clássicos Históricos. Publicada em bancas de jornal e destinada ao público popular, a referida coleção foi criada pela editora Nova Cultural em 1993 e trata de encontros amorosos ambientados em países como Estados Unidos e Inglaterra durante o século XIX. A partir da hipótese de que os romances sentimentais e a relação estabelecida com eles desempenhariam um papel formativo para suas leitoras, procuramos investigar três aspectos das práticas de leitura da coleção: em primeiro lugar, observamos o papel da Clássicos Históricos e das relações mantidas com ela para a aprendizagem relativa à decifração dos livros, isto é, tudo aquilo que dizia respeito à formação de leitores; em segundo lugar, procuramos verificar sua importância na iniciação ou acesso das leitoras à cultura letrada; por fim, diante das representações de modelos femininos, masculinos, de casamento e felicidade investigamos a função da coleção para a formação dos sentimentos amorosos e gerais das mulheres. Para tanto recorremos à fonte oral, recolhida por meio de entrevistas feitas com seis leitoras da coleção Clássicos Históricos, por meio das quais pudemos apreender falas sobre as práticas de leitura de romances sentimentais. Também compõe nosso quadro de fontes a própria coleção Clássicos Históricos, cuja análise permite compreender as representações de leitora e leitura com as quais a editora e autoras da publicação operam. Além disso, de modo a complementar as informações obtidas nas entrevistas, também coletamos depoimentos de leitoras no blog da editora Nova Cultural e em um site de relacionamento. Para analisar os dados, utilizamos os conceitos de prática de leitura, apropriação, circulação (CHARTIER); tática e estratégia (CERTEAU); habitus e campo (BOURDIEU); Socialização Primária (BERGER & LUCKMANN). Pudemos notar, através das entrevistas, que os romances sentimentais são leituras transmitidas de mães ou mulheres mais velhas para jovens leitoras que, a partir desse movimento, assumem tais publicações como suas escolhas privilegiadas. Por conta desse movimento, as moças apreendem o que é a literatura, como ela deve ser lida e uma maneira específica de circular pela cultura letrada com base nos meios de circulação da coleção Clássicos Históricos. / This dissertation, part of history and historiographys education studies, has as objective to understand the reading practices kept by female readers of sentimental novels, particularly, the Clássicos Históricos novel collection. Published in newsstand and intended to popular audience, that collection was created by Nova Cultural publishing house in 1993 and is about problematic loving meetings placed in United States or England along XIX century. From the hypothesis that this sentimental novels and the relation kept with them would play an important formative role to its readers, we aim to investigate three aspects of the collection´s reading practices: at first place, we observed Clássicos Históricos role and the relations kept with it for learning due to book deciphering, namely, everything that concerns about formation of the reader; at second place, we search verify its importance to initiation or readers access to literate culture; at last, face of representations of females, males, marriage and happiness templates we investigate the function of the collection to formation of readers loving and general feelings. To reach these objectives we use the oral source obtained by interviews done with 6 Clássicos Históricos collection readers and through them we could apprehend speeches about sentimental novels reading practices. Its also part of our sources the Clássicos Históricos collection itself, which analyses allow us to understand the representations made of the readers and the reading in which the publishing house and the female authors operate. Furthermore, to complement information obtained at interviews, we have collected too readers statements at Nova Culturals blog and at a relationship site. To analyze those data, we have used concepts as reading practices, appropriation, circulation (CHARTIER); tactics and strategies (CERTEAU); habitus and field (BOURDIEU); primary socialization (BERGAR & LUCKMANN). We could notice through the interviews that sentimental novels readings are transmitted from female older readers to youngest readers that, from that moment, assume those issues as preferential literary chooses. Because this movement the young female readers learn what literature is, how it should be reading and an specific way to circulate around literate culture based on the Clássicos Históricos collections ways of circulation.

Modulação hormonal das alterações psicofisiológicas induzidas pelo uso crônico do anestésico dissociativo ketamina / Hormonal modulation of the psychophysiological changes induced by the chronic use of the dissociative anesthetic ketamine

Brasilino, Lígia Santos Bueno 27 June 2017 (has links)
A ketamina, antagonista não competitivo de receptores NMDA, apresenta potentes efeitos psicomiméticos, sendo capaz de acentuar o estado psicótico de pacientes esquizofrênicos. Uma das áreas cerebrais afetadas por seu uso é o córtex pré-frontal, já que o desempenho em tarefas que dependem de sua atividade é profundamente alterado pela administração aguda de ketamina. Assim como na esquizofrenia, estas alterações podem sofrer influência de fatores hormonais, alterações estas que podem ser explicadas pelos efeitos dos hormônios sexuais femininos, como o estrogênio, os quais apresentam um papel regulador sobre os sistemas dopaminérgicos, serotonérgicos, glutamatérgicos e GABAérgicos, todos afetados pelos efeitos agudos e crônicos do uso de ketamina. Este projeto, portanto, teve como meta avaliar os possíveis efeitos da administração crônica e retirada de ketamina sobre a expressão de comportamentos relacionados à ansiedade humana em ratas da linhagem Wistar, assim como a influência dos hormônios estradiol e a progesterona sobre esta variável. As possíveis alterações farmacológicas induzidas pela administração crônica de ketamina sobre os sistemas dopaminérgicos e serotoninérgicos da divisão pré-límbica (PrL) do córtex pré-frontal medial serão avaliadas através da injeção local de antagonista/agonista específicos. Nossos dados reforçam a ideia de que a ketamina demonstra de forma significativa a expressão da resposta aprendida de medo. E também, os dados mostram que a abstinência da droga altera este comportamento, particularmente a capacidade cognitiva relacionada ao encadeamento de estímulos. Da mesma forma que outras drogas de abuso, estas alterações parecem envolver tanto o sistema dopaminérgico quanto serotoninérgico do CPFm. / Ketamine, a non-competitive antagonist of NMDA receptors, has potent psychomimetic effects, being able to accentuate the psychotic state of schizophrenic patients. One of the brain areas affected by its use is the prefrontal cortex, since performance in tasks that depend on its activity is profoundly altered by the acute administration of ketamine. As in schizophrenia, these changes may be influenced by hormonal factors, which can be explained by the effects of female sex hormones, such as estrogen, which play a role in the dopaminergic, serotonergic, glutamatergic and GABAergic systems, all affected acute and chronic effects of ketamine use. This project therefore aimed to evaluate the possible effects of chronic administration and withdrawal of ketamine on the expression of behaviors related to human anxiety in Wistar rats, as well as the influence of the hormones estradiol and progesterone on this variable. The possible pharmacological changes induced by chronic ketamine administration on the dopaminergic and serotonergic systems of the prelambial (PrL) division of the medial prefrontal cortex will be assessed by specific local antagonist / agonist injection. Our data reinforce the idea that ketamine demonstrates significantly the expression of the learned response of fear. Also, the data show that drug abstinence alters this behavior, particularly the cognitive capacity related to the chaining of stimuli. Like other drugs of abuse, these changes appear to involve both the dopaminergic and serotonergic system of CPFm.

Comportamento de escolha em ratos Sprague Dawley (Rattus norvegicus) sob restrição alimentar / Behavior of choice in Sprague-dawley (Rattus norvegicus) rats under food restriction

Fernandes, Sara Tamiris Cirilo 12 May 2016 (has links)
O comportamento de escolha é entendido como a seleção de uma entre duas ou mais alternativas disponíveis, diferente da preferência, que está relacionada ao tempo despendido respondendo a uma dessas alternativas. Em pesquisas com não humanos, observa-se que os sujeitos escolhem com maior frequência as alternativas nas quais o reforço estará disponível de forma imediata, em pequena quantidade, em comparação com a alternativa na qual o reforço estará disponível somente depois que o animal esperar um tempo determinado (atraso), mas em maior quantidade. Apesar da literatura apresentar dados sobre a influência da restrição alimentar e do sexo do animal em tarefas de aprendizagem, é importante aprofundar a investigação desses aspectos em tarefas de escolha. O objetivo desta pesquisa foi comparar o desempenho de ratos Sprague Dawley (machos e fêmeas) com história de restrição alimentar e ratos controle (com comida ad libitum), em uma tarefa de escolha, em que as alternativas variavam em relação ao atraso para ter acesso à comida e à quantidade de comida disponível. Foram utilizados 24 ratos (12 machos), de linhagem Sprague-Dawley, divididos em dois grupos. O Grupo Controle (C) recebeu dieta ad lib., enquanto o Grupo Restrição (R) teve sua dieta restrita a 80% da dieta do grupo controle. Aos 70 dias de idade, houve uma subdivisão dos grupos: metade dos animais do Grupo C formou o Grupo Controle-Restrito (CR 80% da dieta), e a outra metade o Controle-Controle (CC 100% da dieta). No Grupo R, metade dos animais formou o Grupo Restrito-Controle (RC 100% da dieta) e a outra metade, o Grupo Restrito-Restrito (RR 80% da dieta). Na Etapa 1 os animais exploravam labirinto em U em uma sessão de 10 tentativas. Na Etapa 2 foram realizadas 10 sessões de 16 tentativas de escolha forçada, sendo oito no braço direito, onde havia seis pelotas de ração disponíveis após atraso de 15 s (alternativa LL), e oito no braço esquerdo, com três pelotas de ração disponíveis sem atraso (alternativa SS). Na Etapa 3, foram conduzidas 45 sessões com 30 tentativas (10 forçadas e 20 livres), para verificar o padrão de escolha dos animais dos diferentes grupos em função da disponibilidade de reforço em cada alternativa, do atraso em uma das alternativas e do tempo inicial de espera (tempo T). Os animais de todos os grupos apresentaram preferência pela alternativa SS, independente do sexo ou da dieta. Ao comparar a porcentagem de escolhas dos grupos com relação às dietas foram verificadas diferenças no padrão e nas latências médias de escolha. O grupo RR apresentou latências médias de escolha significativamente inferiores às do grupo CC e um estabelecimento mais rápido de preferência pela alternativa SS que o grupo CC. Apesar de não terem sido encontradas diferenças significativas entre machos e fêmeas nos parâmetros analisados (possivelmente em função do n amostral), verificou-se que fêmeas apresentaram latências menores que machos em todos os grupos, além de porcentagens de escolha pela alternativa SS maiores que os machos. São discutidas hipóteses sobre a influência da dieta e da quantidade de alimento disponível em cada alternativa sobre as escolhas dos grupos. Essas hipóteses são também relacionadas a aspectos evolutivos, referentes às funções desempenhadas por machos e fêmeas na natureza. / The behavior of choice is understood as the selection of between two or more alternatives available, different from the preference, which is related to the time spent by responding to one of these alternatives. In researches with non-human animals, it is observed that the subjects choose more frequently the alternatives on which the reinforcement will be available immediately, in small quantity, in comparison with the alternative in which the reinforcement is available only after the animal expects a certain time (delay), but in greater quantity. Although literature present data on the influence of food restriction and the sex of the animal in tasks of learning, it is important to deepen the investigation of these aspects in tasks of choice. The objective of this research was to compare the performance of rats Sprague Dawley (male and female) with a history of food restriction and control rats (with food ad libitum), in a task of choice, in that the alternatives varied in relation to the waiting time for access to food and the quantity of food available. 24 albino rats (12 males), from Sprague-Dawley lineage was used, divided in two groups. The Control Group (C) received diet ad lib., while the group restriction (R) had their diet restricted to 80% of the diet of the control group. At 70 days of age, there was a subdivision of the groups: half of the animals from group C formed the Group Controle-Restrito (CR - 80% of the diet), and the other half the Controle-Controle (CC - 100% of the diet). In Group R, half of the animals formed the Group Restrito-Controle (RC - 100% of the diet) and the other half, the Restrito-Restrito group (RR - 80% of the diet). In Step 1 the animals explored the labyrinth in U in a session of 10 attempts. In Step 2, there were 10 sessions of 16 attempts of forced choice, being 8 in the right arm, where there were six pellets of ration available after delay of 15 s, and eight in the left arm with three pellets of rations without delay. In Step 3, 45 sessions were conducted with 30 attempts (10 forced and 20 free), tarry check the default choice of animals of different groups in relation to the availability of strengthening in each alternative, the delay in one of the alternatives and the initial time wait time (T). Animals of all groups have preference for the SS alternative, independently of sex or diet. Differences were verified in the pattern and average latencies of choices in comparing the percentage of choices of the groups in relation to the diets. The RR group presented significantly lower average latency in comparison to group CC and a faster preference was established for alternative SS than group CC. Even having no significant differences been found between males and females in the scope studied (possibly due to then sampling), it was verified that females present lower latencies that males in all groups, besides the higher percentages for choosing alternative SS in males. Hypotheses are discussed on the influence of the diet and the quantity of food available in each alternative over the group choices. These hypotheses are also related to evolutionary aspects, referent to functions performed by males and females in nature.

Diferenças associadas ao ciclo estral na reatividade emocional de ratas a estímulos incondicionados e condicionados de medo / Sex and estrous cycle-linked differences in responsiveness to unconditioned, but not conditioned fear stimuli in rats.

Figueiredo, Rebeca Machado de 07 October 2016 (has links)
O desequilíbrio da homeostase emocional tem sido considerado como um mecanismo subjacente aos transtornos de ansiedade e humor. Em fêmeas, as alterações na secreção hormonal durante as diferentes fases do ciclo estral podem ser a base das alterações na reatividade emocional a eventos estressantes. Estudos comportamentais sobre diferenças sexuais no processamento das emoções mostram resultados conflitantes em fêmeas devido às dificuldades na seleção dos melhores modelos animais para testar as diferenças associadas ao ciclo estral. Uma vez que os testes comportamentais foram desenvolvidos em animais do sexo masculino, eles podem não ser apropriados para fêmeas. O presente estudo foi desenvolvido para contribuir nessa linha de pesquisa usando diferentes modelos de animais de medo incondicionado e condicionado, considerando as diferentes fases do ciclo estral das ratas. Comparou-se o desempenho de machos e fêmeas nas quatro fases do ciclo estral em dois testes de medo incondicionado: o switch-off, em que ratos cruzam uma caixa vai-e-vem para desligar uma luz aversiva, e o registro de vocalizações ultrassônicas (VUSs) a 22 kHz emitidos por animais sob o estresse agudo de restrição. Nos testes de medo condicionado, registrou-se o sobressalto potencializado pelo medo e a resposta decongelamento a um contexto aversivo. Em ambos os testes de medo condicionado, a reatividade emocional não se mostrou diferente entre os sexos. No entanto, no que diz respeito ao medo incondicionado, ratas em diestro tardio apresentaram maior reatividade emocional em desligar a luz intensa e maior emissão de VUSs em resposta à restrição em relação a outras fases do ciclo. Estes achados sugerem que o perfil hormonal durante a fase do diestro 2 pode aumentar a reatividade emocional de ratas frente a estímulos inatos, porém não àqueles aprendidos. / Dysfunctional emotional regulation has been implicated as a potential mechanism underlying anxiety and mood disorders. Changes in hormonal secretion during the different phases of the estrous cycle may underlie changes in emotional reactivity to stressful events in female animals. Previous behavioral studies of sex differences in emotion processing in females have yielded conflicting results. This may be due to the range of different behavioral tests used and difficulties in selecting the best animal models to test for estrous cycle-linked differences in responsiveness. Furthermore, the commonly used behavioral tests were developed in male animals and it may not be appropriate to translate directly the protocols from males to females. In the present study we have attempted to address these problems by using different animal models of anxiety based on tests for unconditioned or conditioned fear. We compared the performance of male rats and female rats at four stages of the estrous cycle defined by differences in vaginal cytology. To test for unconditioned fear, we used two tests: a light switch- off test, in which rats escape to the other compartment of a shuttle-box to turn off an aversive light and recordings of 22 kHz ultrasound vocalizations (USVs) during acute restraint stress. For the conditioned fear paradigm, we used fear potentiated startle in an aversive context and conditioned freezing using an aversive context as the conditioned stimulus. In both tests of conditioned fear there were no gender or estrous cycle-linked differences in emotional reactivity. However, with respect to unconditioned fear, female rats in late diestrus showed greater emotional reactivity expressed as switch-off responses to a light environment and USVs in response to restraint compared to other phases of the cycle. These findings suggest that the hormonal profile during the late diestrous phase may predispose to up-regulated emotional reactivity in rats facing emotional challenges to unconditioned, but not conditioned fear- inducing stimuli.
