Many exiting instruments are questionnaires for parents, and most of them focus on children, therefore little is known about sensory perception in adults. Given the lack of brazilian intruments to evaluate the hability of sensory processing and questionnaires that can access the real experience of who lives this reality, this study aims to translate to brazilian portuguese and culturally adapt the Sensory Perception Quotient, an instrument of self report that can access sensory reactivity in adults, evaluating five basic modalities, that can be hypo or hyper –reactive, avoiding value judgment. The purpose of this study, therefore, is to translate to brazilian portuguese and adapt culturally to the brazilian culture of the Sensory Perception Quotient, conducting a study within a scope of a non-experimental non-longitudinal descriptive research, and the following steps: translation, back-translation, revision by a specialist comittee on analysis, evaluation of he scoring and the verification of the instrument’s internal consistency. Sample was constituied of 87 participants, ages 18 to 52 years. The results obtained by the application of total questionnaire translated and adapted, already modified in 53 questions in relation to it’s original version, aloud to notice that it is understandable and shows intern consistency little under of desirable, having only the short version with desirable intern consistency. These observations indicate that the search for evidence of validy of the short version of the instrument, realized through new researches, with other applications of the translated version and adapted in this study, will make it possible to applicate in Brazil. Is recommened caution with full questionnaire in the disscution part of this study. / Considerando-se o fato de que aproximadamente 90% dos indivíduos com TEA mostram algum déficit na percepção sensorial junto ao fato da inclusão do critério sensorial atípico no Manual de Diagnóstico e Estatística dos Transtornos Mentais 5.ª edição (DSM-5) para diagnóstico de TEA, há necessidade de se ter instrumentos que possam acessar esses constructos possibilitando mais pesquisas. Muitos instrumentos existentes são questionários para pais, e a maioria se volta para crianças, assim pouco se sabe sobre a percepção sensorial em adultos. Diante da falta de instrumentos brasileiros para avaliar a habilidade de processamento sensorial e questionários que possam acessar a experiência daquele que vive diretamente essa realidade, este estudo objetivou traduzir para o português do Brasil e adaptar culturalmente o Sensory Perception Quotient, um instrumento de auto relato que acessa a reatividade sensorial em adultos, avaliando as cinco modalidades básicas, podendo ser hipo ou hiper-reativo, evitando julgamento de valores. O presente estudo se encaixa no modelo de pesquisa não experimental, transversal, descritiva, contendo os seguintes passos: tradução, retrotradução, revisão por um comitê de especialistas, avaliação das pontuações e verificação da consistência interna do instrumento. A amostra foi constituída de 87 participantes, com idades entre 18 a 52 anos. Os resultados obtidos através da aplicação do questionário total traduzido e adaptado, já com mudanças em 53 perguntas em relação à versão original, permitiram observar que ele é compreensível e apresenta consistência interna pouco abaixo do desejável, apenas com a versão reduzida (short) possuindo consistência interna adequada. Essas observações indicam que a busca de evidências de validade do instrumento da versão reduzida, realizada através de novas pesquisas, com outras aplicações da versão traduzida e adaptada neste estudo poderá tornar possível sua utilização no Brasil. Recomenda-se cautela maior com o questionário total na discussão do trabalho.

Magister Commercii - MCom / This study was undertaken to determine the relationship between the emotional intelligence and burnout levels of police constables of the South African Police Service (SAPS) in the Western Cape. The field work of constables includes situations in which police officers need to make quick decisions involving life and death. Constables regularly have to deal with and are exposed to dangerous and violent situations (Plani, Bowley & Goosen, 2003). There are certain skills which a police officer needs to demonstrate. These skills include the ability to make decisions promptly and accurately; the ability to favourably interact with the community and to observe, retain and recall detailed information. However, these skills are affected when the police officer experiences feelings of stress and burnout (Goodman, 1990). One factor that might help police officers with these skills is emotional intelligence (Levert, Lucas & Ortlepp, 2000; Mayer & Salovey, 1997). Given the nature of policing, the potential benefit to the SAPS employing a police officer with high emotional intelligence to deal with burnout, would be the desired attribute. A simple random sample of N=108 police constables participated in this study. The Emotional Quotient-Inventory (EQ-i) and the Burnout Measure (BM) were administered. Data were analysed using the Statistical Package for Social Science (SPSS) version 15.0. Cronbach reliability estimates for the EQ-i ranged from .87 to .90 and for the BM was .93. Positive and negative relationships were found between emotional intelligence dimensions: self-awareness (r=.-393, p>0.01), self-regulation (r=.-485, p>0.01), motivation (r=.-442, p>0.01), empathy (r=.-394, p>0.01) and social skills (r=.-383, p>0.01), [N=108] and police officers’ total burnout levels. The results indicated that the more self-aware, self-regulated, motivated, empathetic and socially inclined police officers were, the less likely police officers were to experience burnout. The results also indicated that the less self-aware, self-regulated, motivated, empathetic and socially inclined police officers were, they would be more likely to experience burnout. The exploratory factor analysis yielded a two factor structure for the individual on the emotional intelligence dimensions namely, self-awareness and empathy. A single factor was found for the manager consisting of the original five dimensions of the EQ-i. There was a moderate to strong negative correlation between total self-awareness (r=.-206), self-regulation (r=.-263), motivation (r=.-299), empathy (r=.-268) and social skills (r=.-311), [N=108, p>0.01] and police officers’ total burnout levels. This finding suggests that the more police officers viewed their manager to be self-aware, self-regulated, motivated, empathetic and socially inclined, the less likely they were to experience burn-out. The results of the multiple regression analysis show that police officers’ self-regulation appeared to be the only significant reliable predictor of burnout. The findings of this study provide an important contribution to expanding the body of literature and knowledge concerned with the emotionally intelligent constable which influences their burnout levels / South Africa

The main objective of this thesis was to examine the independent effects of sleep duration and timing on appetite, food reward and energy balance. Study 1 investigated the associations between satiety quotient (SQ) with habitual, self-reported sleep duration, quality and timing. No significant associations were noted between SQ and sleep parameters. Short-duration sleepers had a lower mean SQ vs. those with ≥7h sleep/night (P=0.04). Study 2 evaluated associations between changes in sleep duration, efficiency and timing with changes in next day food reward. Greater sleep duration and earlier wake-times were associated with greater food reward (P=0.001). However, these associations were no longer significant after controlling for elapsed time between awakening and completion of the food reward task. Study 3 examined the effects of 50% sleep restriction (SR) anchored during the first (delayed bedtime) or second (advanced wake-time) half of the night on appetite, SQ, food reward, energy intake (EI) and energy expenditure (EE). Greater appetite ratings and explicit high-fat food reward were noted following SR with an advanced wake-time vs. control and SR with a delayed bedtime (P=0.03-0.01). No difference in SQ was noted between sessions. Energy and carbohydrate intakes were greater on day 2 and over 36h in the delayed bedtime vs. control session (P=0.03). Activity EE and moderate-intensity physical activity (PA) time were greater following delayed bedtime vs. control and advanced wake-time on day 1, whereas vigorous-intensity PA time was greater following advanced wake-time vs. delayed bedtime on day 1 (P=0.01-0.04). Greater sleep quality and slow-wave sleep duration between SR sessions were associated with lower EI and increased vigorous-intensity PA time, respectively (P=0.01-0.04). Collectively, these findings suggest that appetite, SQ and food reward are influenced by sleep parameters, but these changes may not alter EI. These findings also suggest that individuals with greater sleep quality in response to SR had greater vigorous-intensity activity time and lower EI.

It is the purpose of the writer to discover if there is any significant difference between the teacher ratings of boys and girls with equated intelligence quotients. And if such differences are found to exist, an attempt will be made to determine to what extent they prevail.

The problem in this experiment is to try to determine if the use of certain materials during the first semester of the first school year of a group of children will cause the intelligence quotients and achievements of these children to improve.

The correlation between home environment and educational performance is addressed in this study.

Rhizopus oryzae is a prominent strain for producing fumarate, where biomass growth precedes fumarate production. The natural bio film growth of R. oryzae as fungal mat was investigated using different glucose addition strategies in a novel fed-batch fermenter. Batch growth was compared through three fed-batch runs, each with a different glucose addition strategy. The fed-batch runs involved a constant glucose feed (CGF) of 0.075 g h-1 and controlled glucose feeds in order to keep the respiration quotient (RQ) at either 1.3 mol CO2 mol-1 O2 (RQ1.3) or 1.1 mol CO2 mol-1 O2 (RQ1.1). Ethanol overflow via the established Crabtree mechanism was completely negated for the CGF and RQ1.1 runs, while the batch and RQ1.3 runs exhibited significant ethanol formation. Biomass yield on glucose was found to be 0.476 g g-1 (RQ1.1), 0.194 g g-1 (RQ1.3), 0.125 g g-1 (CGF) and 0.144 g g-1 (batch). The results indicate a three-fold improvement in biomass yield when comparing the batch run with the RQ1.1 run. In addition, the RQ1.1 run resulted in zero detectable byproducts, unlike the batch scenario where pyruvate and fumarate were associated with ethanol formation. Clear evidence is provided that glucose overflow can be fully eliminated during R. oryzae growth, significantly affecting the biomass yield on glucose. / Dissertation (MEng (Chemical Engineering))--University of Pretoria, 2021. / University of Pretoria postgraduate bursary / CSIR Inter-bursary Programme / Chemical Engineering / MEng (Chemical Engineering) / Unrestricted

<div>Conceptual aerospace mission design has typically been performed in a computationally intensive and iterative manner. The introduction of modern computing has resulted in the widespread adoption of various numerical methods. As a result, useful information associated with the optimal solution is largely ignored. Optimization through indirect methods, while still computationally intense, leverages this information and also reveals a much deeper mathematical structure. This mathematical structure provides the gateway to reformulating the problem definition to one with certain desirable properties. In the presence of symmetries and constants-of-motion, the dynamical systems of indirect methods live in a reduced dimensional quotient manifold. Studies leveraging this reduced dimensional quotient manifold may benefit in performance by using fewer operations per iteration.</div><div><br></div><div>Many limitations prevent the use of these quotient manifolds in practical aerospace mission design. The five main issues include (1) rephrasing indirect methods in terms of differential geometry in an efficient manner, (2) Pontryagin's minimum principle generating a large number of valid dynamical systems, (3) implementing reduction in a global manner for highly non-linear systems, (4) numerical boundary-value problem solvers not supporting missions on quotient manifolds, and (5) scalability of the methods to real aerospace missions. This work addresses all five issues.</div><div><br></div><div>In previous studies, computer algebra systems have been proven to be an effective tool for automating complex indirect methods. However, when posed in the language of differential geometry, the majority of support from digital software is lost. A version of indirect methods is recasted using differential geometry that effectively retains all information of so-called traditional methods. Exploitation of the anti-symmetric differential structure enables large-scale problems to be studied.</div><div><br></div><div>Root-solving the stationary Hamiltonian condition may generate several, potentially valid dynamical systems. Each system must be evaluated at every point along the trajectory using Pontryagin's minimum principle. This process prohibits later analytical derivations on the dynamical system. In the Integrated Control Regularization Method, the control law is posed as a state of the dynamical system with an equation-of-motion, thereby moving complicated root-solving to the boundary where it is solved once. Introduction of the control law as a new state is done using geometric adjoining methods where the original mathematical structure of the problem is preserved.</div><div><br></div><div>Reduction is traditionally studied in a topological context where there is a wealth of information. In terms of aerospace missions, there are very few applications in existence. These traditional studies rely on the quotient of entire global spaces. This is impossible to apply on non-integrable, non-linear dynamical systems. To get around this, a compact procedure is developed where the Lie algebra identifies dynamical sub-systems that may be effectively eliminated. This removes the reliance of integrability on the symmetry space.</div><div><br></div><div>In reduction, various dimensions desirable to a designer may be eliminated from the system defined on a reduced dimensional quotient manifold. Crucial to satisfying mission requirements, present day numerical solvers do not have the capability to perform the necessary reconstruction. A modified collocation and shooting algorithm with this functionality is given and a numerical example of a problem on a reduced dimensional quotient manifold is explored.</div><div><br></div><div>Including reduction, nearly all advanced analytical techniques on dynamical systems introduce their own set of complexities. Typical aerospace designers do not want to deal with the many difficulties associated with each technique. By formalizing optimal control theory as a composable functorial process, these advanced strategies are compartmentalized with well-defined and predictable results. This enables the use and reuse of many different techniques in series, vastly improving on the automation of indirect methods.</div>

Einleitung: Die Dysbalance proangiogener (Placental Growth Factor = PlGF) und antiangiogener Faktoren (soluble fms-like tyrosine kinase 1 = sFlt-1) gilt heute als pathophysiologische Grundlage bei der Entstehung einer Präeklampsie (PE), eines HELLP-Syndroms (Haemolysis, Elevated Liver enzymes, Low Platelets) oder einer intrauterinen Wachstumsretardierung (IUGR). Der sFlt1/PlGF-Quotient, ein sensitiver und robuster diagnostischer Marker, ist bereits Wochen vor der Krankheitsmanifestation erhöht. Ziel dieser Studie war es, die Wertigkeit des sFlt1/PlGFQuotienten als prädiktiven Faktor bei Risikopatientinnen zu untersuchen. Patienten und Methode: In diese prospektive Studie wurden 68 Patientinnen mit einer Einlingsschwangerschaft und mindestens einem Risikofaktor für das Auftreten einer PE, eines HELLP-Syndrom oder einer IUGR im Schwangerschaftsverlauf eingeschlossen. Die Patientinnen wurden je nach Verlauf der Schwangerschaft in eine Gruppe mit Symptomen (Fallgruppe) und eine Gruppe ohne Symptome (Kontrollgruppe) für eine der oben genannten Erkrankungen unterteilt. Der sFlt1/PlGF-Quotient wurde bei der Aufnahme in die Studie und im weiteren Schwangerschaftsverlauf bestimmt. Ergebnisse: Eine PE, ein HELLP-Syndrom oder eine IUGR trat bei 41 % der Risikopatientinnen auf. Der absolute Wert des sFlt-1/PlGF-Quotienten war nur bei der Gruppe mit Symptomen auf ≥ 85 erhöht und zeigte sich in der 25 + 0-31 + 0 SSW (p = 0,005) und ab der 35 + 0 SSW (p = 0,044) als prädiktiver Faktor für eine PE, ein HELLP-Syndrom oder eine IUGR. Ab 7–10 Wochen vor der Entbindung war, in der Fallgruppe stärker als in der Kontrollgruppe, ein Anstieg des sFlt1/PlGFQuotienten zu beobachten. Dieser war 0–2 Wochen vor der Entbindung bei beiden Gruppen (Kontrollgruppe (MW ± SA 66,9 ± 134) vs. Fallgruppe (MW ± SA 393,3 ± 147,4, p = 0,021) am stärksten und zeigte sich ebenfalls als prädiktiver Faktor für eine der genannten Schwangerschaftserkrankungen (p = 0,025). Schlussfolgerung: Bei Risikoschwangeren kann der sFlt1/PlGF-Quotient für die Einschätzung des individuellen Risikos für eine PE, ein HELLP-Syndrom oder eine IUGR im Schwangerschaftsverlauf genutzt werden. Wiederholte Messungen des Quotienten versprechen eine risikoangepasste Betreuung dieser Patientinnen.
