No Brasil há mobilização, por meio dos gestores de suas políticas públicas, no sentido de diminuir o número de cesarianas, episiotomias e outras intervenções que se revelaram inadequadas quando utilizadas sem indicação clínica. O objetivo desta pesquisa é estudar a relação entre intervenções clínicas e cirúrgicas no trabalho de parto e parto e a saúde física e psicológica (transtornos mentais menores) das mulheres no puerpério imediato, mediato e tardio de um hospital público do interior do Estado de São Paulo. Trata-se de um estudo de caráter descritivo, com abordagem quantitativa, no qual foram entrevistadas 278 mulheres no puerpério imediato e mediato (em torno do 10o dia), com perguntas referentes ao seu estado físico e psicológico. No 40o dia pós parto foi possível entrevistar 130 mulheres com o objetivo de analisar possíveis intercorrências tardias. A análise estatística inicial foi exploratória, com descrição de freqüência dos eventos e testes bivariados para nível de significância de 95%. A análise da medida de efeito foi realizada através da prevalência para observar complicações no puerpério imediato e tardio de acordo com as categorias de cada variável. Os resultados mostraram índices de analgesia e parto fórcipe acima dos citados em literatura. O parto fórcipe se mostrou fator de risco para lacerações perineais mais severas e Rns com Apgar menor que 7 no 1º minuto. / Abstract: The interventions during labor and delivery have been subject of national and international agency debates. In Brazil, health policies has been implemented in order to reduce the rates of surgical delivery, episiotomies, and other birth procedures revealed as inadequate when used without clinical indication. The aim of this study is to identify the relationship between interventions during labor and delivery and, the physical and psychological women's condition in the puerperal period in a public hospital in the State of São Paulo. It's a quantitative descriptive study that depicts the assistance received in the labor and its association to the kind of delivery, the interventions performed, the occurrence of depression and complications to the mothers in their puerperium. A sample of 278 women have been interviewed about their physical and psychological state on the 10th day of their puerperium, and 130 out of these 278 on the 40th day. An analysis was undertaken for potential risky factors, with outcome variable being presence or absence of complications. Confidence intervals at 95% level were calculated for each variable. Prevalence was calculated to identify the relationship between delivery clinical and surgical procedures and woman's health during puerperium period. The results showed a prevalence of analgesia and instrumental delivery above the expected by the current literature. Forceps delivery was a risk factor for more severe perineal lacerations and for newborns with and Apgar index lower than 7 in the first minute of life. / Mestrado / Epidemiologia / Mestre em Saude da Criança e do Adolescente

Foram preparados adutos de tetracloreto de titânio com ligantes orgânicos monodentados do tipo TiC14.2L, onde L = CH3CN, CD3CN, C2H5CN, C2H3CN, C6H5CN, C5H5N, C5D5N, (CH3)2S e (C2H5)2S. Foram feitas as previsões espectrais, pela aplicação da teoria de grupo, para o esqueleto do aduto TiCl4.2L, tendo em vista as três possíveis configurações: D4h, D2d e C2v. Os espectros vibracionais foram obtidos em estado sólido, sendo que para os adutos TiC14.2CH3CN e TiC14.2C2H5CN também o foram em solução, usando como solventes os respectivos ligantes. Os espectros Raman de todos os compostos e os espectros infravermelho dos adutos com os ligantes: acetonitrila deuterada, piridina deuterada e dietilssulfeto, são originais. Para maior facilidade na discussão e interpretação dos espectros os adutos foram agrupados em três conjuntos, caracterizados pela semelhança dos espectros vibracionais, especialmente, Raman. O primeiro conjunto compreende os adutos com nitrilas, o segundo os com piridina e o terceiro os com sulfetos. A análise dos espectros sugere que: a) Os compostos de adição do primeiro conjunto pertencem à configuração cis-octaédrica, grupo pontual C2v. b) O esqueleto dos adutos do segundo conjunto possuem configuração trans-octaédrica, simetria D4h. Para os complexos do terceiro conjunto não foi possível concluir, com base nos espectros vibracionais, a configuração do esqueleto. Foi feita uma tentativa de atribuição das frequências dos esqueletos para os adutos do primeiro e do segundo conjunto, com a utilização de vários argumentos empíricos. São discutidos alguns deslocamentos de frequências do ligante devido à coordenação. A análise em coordenadas normais, usando o campo de força de Urey-Bradley com duas interações, para os adutos de tetracloreto de titânio com acetonitrila e acetonitrila deuterada, confirma a atribuição feita. / Abstract not available.

The human ankle joint is hypothesized to be a primary controller of support, propulsion and steering during locomotion. A series of experiments were initiated to understand ankle plantarflexor muscle kinematics and kinetics in normal and pathological gait, and to define the specific locomotor demands of community ambulation. Additional experiments were then conducted to quantify the effects of walking speed on plantar pressures and centre of mass motion, to illuminate the role of the ankle in acceleration and deceleration during walking, and to examine how humans alter their kinematics and kinetics to turn. The results of these experiments provide support for the hypothesis that the ankle joint is important in a wide range of locomotor movements beyond walking straight ahead at constant speed. The ankle appears instrumental in adapting to different walking speeds, altering both the pressures on specific regions the plantar surface and the motion of the centre of mass across a range of speeds. The ankle also has subtle kinetic changes that appear to modulate acceleration and deceleration during single limb stance. For turning, the ankle plays a role during slowing into the turn and accelerating after the turn, but mediolateral shears appear to alter the trajectory of the body to negotiate a corner and the external hip rotators appear to rotate the trunk toward the new direction of travel. This work extends our understanding of the ankle in functionally relevant gait activities beyond simple straight-ahead walking at constant speed. The published papers included in this supporting statement have been cited by 180 different subsequent peerreviewed publications, suggesting that this work has had some impact on the field.

Libresse campaign #Bloodnormal aims to raise awareness about periods as a taboo subject. Similar to how Libresse is trying to make a change, more and more companies are starting to create norm breaking content. The question is how the public see these commercials. Do they think it is a method to get more brand authenticity or do they think it will make a real change? This study aims to investigate how young, female students experiences and discuss Libresse commercial “Blood Normal”. It will mainly focus on menstrual norms and the brand Libresse. To examine this we have used a reception method with qualitative interviews. By showing the respondents the film “Blood Normal” and later asking them questions, the method made it possible for us to see how the students interpret the film, the menstrual norms and the brand. The theoretical framework for this study is based on taboos, myths, studies on media effects and encoding/decoding. These theories helped us distinguish how the female students interacted and related to “Blood Normal”. By adding theories about legitimacy and corporate social responsibility we furthered examined how Libresse communicates and creates a relationship with their audience to strengthen their brand. The analysis showed that the respondents experienced menstruation as socially unacceptable in certain situations. They explained that “Blood normal” showed scenes that both mirrored and differed from their own experience of menstruation. It was also clear that they found the norm breaking content positive, which for the majority led to a higher trust in the brand. An important question for the respondents was that Libresse stood up for women, which could show that Libresse have a good knowledge about their target group. The commercials biggest effect on the respondents was in the end a bigger discussion about menstrual taboos, which for the majority also contributed to a higher trust for the brand.

The mediation analysis has been used to test if the effect of one variable on another variable is mediated by the third variable. The mediation analysis answers a question of how a predictor influences an outcome variable. Such information helps to gain understanding of mechanism underlying the variation of the outcome. When the mediation analysis is conducted on hierarchical data, the structure of data needs to be taken into account. Krull and MacKinnon (1999) recommended using Multilevel Modeling (MLM) with nested data and showed that the MLM approach has more power and flexibility over the standard Ordinary Least Squares (OLS) approach in multilevel data. However the MLM mediation model still has some limitations such as incapability of analyzing outcome variables measured at the upper level. Preacher, Zyphur, and Zhang (2010) proposed that the Multilevel Structural Equation Modeling (MSEM) will overcome the limitation of MLM approach in multilevel mediation analysis. The purpose of this study was to examine the performance of the MSEM approach on non-normal hierarchical data. This study also aimed to compare the MSEM method with the MLM method proposed by MacKinnon (2008) and Zhang, Zyphur, and Preacher (2009). The study focused on the null hypothesis testing which were presented by Type I error, statistical power, and convergence rate. Using Monte Carlo method, this study systematically investigates the effect of several factors on the performance of the MSEM and MLM methods. Designed factors considered were: the magnitude of the population indirect effect, the population distribution shape, sample size at level 1 and level 2, and the intra-class correlation (ICC) level. The results of this study showed no significant effect of the degree of non-normality on any performance criteria of either MSEM or MLM models. While the Type I error rates of the MLM model reached the expected alpha level as the group number was 300 or higher, the MSEM model showed very conservative performance in term of controlling for the Type I error with the rejection rates of null conditions were zero or closed to zero across all conditions. It was evident that the MLM model outperformed the MSEM model in term of power for most simulated conditions. Among the simulation factors examined in this dissertation, the mediation effect size emerged as the most important one since it is highly associated with each of the considered performance criteria. This study also supported the finding of previous studies (Preacher, Zhang, & Zyphur, 2011; Zhang, 2005) about the relationship between sample size, especially the number of group, and the performance of either the MLM or MSEM models. The accuracy and precision of the MLM and MSEM methods were also investigated partially in this study in term of relative bias and confidence interval (CI) width. The MSEM model outperformed the MLM model in term of relative bias while the MLM model had better CI width than the MSEM model. Sample size, effect size, and ICC value were the factors that significantly associate with the performance of these methods in term of relative bias and CI width.

>Magister Scientiae - MSc / The problem of optimal investment has been extensively studied by numerous researchers in order to generalize the original framework. Those generalizations have been made in different directions and using different techniques. For example, Perera [Optimal consumption, investment and insurance with insurable risk for an investor in a Levy market, Insurance: Mathematics and Economics, 46 (3) (2010) 479-484] applied the martingale approach to obtain a closed form solution for the optimal investment, consumption and insurance strategies of an individual in the presence of an insurable risk when the insurable risk and risky asset returns are described by Levy processes and the utility is a constant absolute risk aversion. In another work, Sattinger [The Markov consumption problem, Journal of Mathematical Economics, 47 (4-5) (2011) 409-416] gave a model of consumption behavior under uncertainty as the solution to a continuous-time dynamic control problem in which an individual moves between employment and unemployment according to a Markov process. In this thesis, we will review the consumption models in the above framework and will simulate some of them using an infinite series expansion method − a key focus of this research. Several numerical results obtained by using MATLAB are presented with detailed explanations.

Let (X, Y) be bivariate normal random vectors which represent the responses as a result of Treatment 1 and Treatment 2. The statistical inference about the bivariate normal distribution parameters involving missing data with both treatment samples is considered. Assuming the correlation coefficient ρ of the bivariate population is known, the MLE of population means and variance (ξ, η, and σ2) are obtained. Inferences about these parameters are presented. Procedures of constructing confidence interval for the difference of population means ξ – η and testing hypothesis about ξ – η are established. The performances of the new estimators and testing procedure are compared numerically with the method proposed in Looney and Jones (2003) on the basis of extensive Monte Carlo simulation. Simulation studies indicate that the testing power of the method proposed in this thesis study is higher.

The problem of this study was to ascertain the relationship of students' differential perception of a campus environment to some personality characteristics. The following correlates of perception were considered: personality traits, length of stay in college, sex, college entrance scores, academic marks, and leadership roles. The major conceptual framework of this study included Kelly's (1955) psychology of personal constructs and Snygg and Combs' (1959) phenomenological determinant of behavior postulate. The subjects of this study included 594 students enrolled at the Bukidnon Normal College, Philippines, during the school year 1970-71. The College and University Environment Scales of C. Robert Pace (1966) and the new Edwards Personality Inventory (1966) were the two major instruments used in the study. In addition, the class advisers evaluated the students' leadership qualities using the Leadership Rating Form. Means, standard deviations, analysis of variance, the F test of significance, Duncan's New Multiple Comparison Test, and the Pearson Product-Moment Correlation Coefficient were the statistical techniques used in the analysis of data. The results showed that the freshmen, sophomore, junior and senior students had a consensus of the various dimensions that make up the school environment. It was found that the negative perceivers of campus environment tended to have some aggressive personality traits, while positive perceivers of campus environment tended to have some passive personality traits. In general, students tended to rate the campus environment lower as they stayed longer in the campus. Males were found to rate the campus environment lower than females. Furthermore, it was found that the students' perception of a campus environment was negatively related to individual academic performance and leadership roles. Implications from the findings were made for counselors, faculty members and school administrators for the improvement of various educational programs at the college. The major conclusion of the study is that students in the college have a consensus perception of the campus environment and that those with positive and negative perceptions of the environmental press have some personality characteristics related to their manner of evaluating the institutional image. / Education, Faculty of / Graduate
