What is there to correct? : LGBTQI People’s Understanding of Sexual and Gender-based Violence in South Africa – A qualitative Study

Odell, Amanda, Udd, Julia January 2022 (has links)
This thesis is a Minor Field Study carried out in Cape Town, South Africa, during March - May 2022. South Africa is suffering a high level of sexual and gender-based violence. LBGTQI people are extra vulnerable when it comes to sexual and gender-based violence, especially when it comes to corrective rapes. The aim of study was therefore to investigate how people from the LGBTQI community in South Africa understands the problem with sexual and gender-based violence and how they perceive that the Government is addressing these issues. To answer our three research questions, we used focus group interviews to gather data. Our research shows that the sexual and gender-based violence is a widespread phenomenon and is affected by intersectional inequalities. Even though South Africa by law has forbidden any discrimination based on sexuality after abolishing the Apartheid regime, there still seems to be a gap between what the Government is constituting and what the citizens, institution, and society values.

Availability Analysis for the Quasi-Renewal Process with an Age-Dependent Preventive Maintenance Policy

Intiyot, Boonyarit 26 September 2007 (has links)
A quasi-renewal process is more realistic in modeling the behavior of a repairable system than traditional models such as perfect repair and minimal repair since it reflects the deterioration process of the system over time while traditional models do not. The quasi-renewal parameter is set to a value between 0 and 1 to indicate the rate of deterioration. Moreover, a quasi-renewal process can also be used to model the increasing time of maintenance actions due to the increasing difficulty of maintaining an aging system by setting the parameter to a value larger than 1. We construct a model where the operating times follow a quasi-renewal process and the corrective/preventive maintenance times follow another quasi-renewal process. A quasi-renewal function and two equivalent point availability expressions are developed for the model described by a quasi-renewal process with and age-dependent preventive maintenance policy. In addition, numerical results from various theoretical distributions are obtained to illustrate the behavior of the models. The two equivalent point availability functions each contains an infinite sum and must be truncated to obtain a numerical approximation. The two approximated point availability functions form upper and lower bounds on the real value. The bounds are useful for determining the result accuracy, which can be arbitrarily increased by adding more terms to the truncated summation. Our framework provides a new time-dependent availability model for a non-stationary process with a preventive maintenance policy without any cost structure or optimization problem. / Ph. D.

Upset Events At Wastewater Treatment Plants: Implications for Mitigative Strategy Development and Bioreactor Microbial Ecology

Pinto, Ameet John 15 January 2010 (has links)
This study consists of three research phases. First, we developed corrective action strategies to mitigate the impact of calcium hypochlorite and cadmium pulse shocks for the Plum Island Wastewater Treatment Plant (WWTP) in Charleston, SC. The corrective action strategies were developed in consultation with industrial consultants and operational personnel from the utility. These strategies were tested using a laboratory scale system, which was constructed and operated similar to the parent facility. Two corrective actions were tested for calcium hypochlorite, while only one strategy was tested for the cadmium at the laboratory scale. This study shows that no corrective action strategies are required for an acute hypochlorite stress. This is due to the fact that hypochlorite is highly reactive and dissipates rapidly on contact with the wastewater matrix, thus causing only low level process deterioration. In fact, implementation of corrective action strategies results in greater process deterioration as compared to the non-intervention approach. The corrective action tested for cadmium stress showed potential for reducing the peak impact of the toxin and allowed for faster process recovery as compared to the unstressed control. For the second phase, the corrective actions were tested at a pilot scale facility operated at the Plum Island wastewater treatment plant. We tested two different corrective action strategies for cadmium, while only one strategy was tested for hypochlorite during the pilot scale study. Similar to the laboratory scale experiments, we conclude that no mitigative approaches are necessary for an acute hypochlorite stress. Additionally, the implementation of mitigative approaches for the pilot scale cadmium stress events resulted in greater process deterioration as compared to the non-intervention approach. In contrast to the laboratory scale experiments, theoretical effluent blending calculations showed that corrective actions may not reduce the impact of the cadmium stress. This was attributed to the lower intensity of process deterioration caused by the simulated cadmium stress. The pilot scale study shows that prior to implementing a corrective action strategy, the operator should determine the probable extent of process deterioration due to the detected chemical contaminant before deciding if a corrective action is needed. The pilot scale study also evaluated the effectiveness of current sensor technologies towards the upstream detection of influent anomalies and reliable monitoring of process performance during an upset event. Multivariate analysis on the rate of change of influent sensor signals was reliably able to detect the presence of both toxins tested during this study. For the third phase of this research, we investigated the impact of cadmium stress on the structure and function of bioreactor microbial communities. We observed significant increases in post-stress heterotrophic and autotrophic bacterial respiration rates for the bioreactors subjected to cadmium stress. The higher respiration rates were due to an increase in bacterial abundance in the cadmium stressed reactors. We were also able to show that the increase in bacterial abundance was not due to changes in community structure or due to cadmium induced deflocculation. In fact, this study demonstrates that transient cadmium stress reduces predator abundance within the activated sludge community and this reduction in predator grazing was responsible for the increase in bacterial abundance. This research highlights the importance of higher life forms, specifically eukaryotic microorganisms, in regulating bacterial community dynamics in systems undergoing chemical perturbations. / Ph. D.

Oral Corrective Feedback Practices in Third Turns of Initiation-Response-Feedback Sequences : An investigation into the Swedish context

Lind, Kajsa January 2024 (has links)
This study aims to expand on the existing research regarding teachers’ oral feedback practices in third turns of initiation-response-feedback (IRF) sequences. There is a gap in the existing research on oral corrective feedback practices in third turns of IRF sequences in the context of Swedish upper secondary school. The aim of this study is to fill some of that gap by providing results and insights from the Swedish context of upper secondary school. A classroom audio recording of a teacher’s classroom talk from an English class with second year students was subjected to conversation analysis to discover general patterns of this teacher’s oral corrective feedback practices in the third turn of IRF sequences. It emerged that implicit corrective feedback practices were frequent, with conversational recasts being among the most common types of feedback. The result of this study thus turned out to be in line with what previous research had found to be common oral corrective feedback practices among teachers.

Minimally Corrective, Approximately Recovering Priors to Correct Expert Judgement in Bayesian Parameter Estimation

May, Thomas Joseph 23 July 2015 (has links)
Bayesian parameter estimation is a popular method to address inverse problems. However, since prior distributions are chosen based on expert judgement, the method can inherently introduce bias into the understanding of the parameters. This can be especially relevant in the case of distributed parameters where it is difficult to check for error. To minimize this bias, we develop the idea of a minimally corrective, approximately recovering prior (MCAR prior) that generates a guide for the prior and corrects the expert supplied prior according to that guide. We demonstrate this approach for the 1D elliptic equation or the elliptic partial differential equation and observe how this method works in cases with significant and without any expert bias. In the case of significant expert bias, the method substantially reduces the bias and, in the case with no expert bias, the method only introduces minor errors. The cost of introducing these small errors for good judgement is worth the benefit of correcting major errors in bad judgement. This is particularly true when the prior is only determined using a heuristic or an assumed distribution. / Master of Science

Noticeability of corrective feedback, L2 development and learner beliefs

Kartchava, Eva 04 1900 (has links)
Cette étude quasi-expérimentale a pour but de 1) comparer la prise en compte et les effets de trois conditions rétroactives, à savoir la reformulation, l’incitation et un mélange des deux techniques, 2) déterminer le lien entre la prise en compte et l’apprentissage, et 3) identifier l’effet des perceptions des apprenants quant à la rétroaction corrective sur la prise en compte et l’apprentissage. Quatre groupes d’apprenants d’anglais langue seconde ainsi que leurs enseignants provenant d’un CEGEP francophone de l’île de Montréal ont participé à cette étude. Chaque enseignant a été assigné à une condition rétroactive expérimentale qui correspondait le plus à ses pratiques rétroactives habituelles. La chercheure a assuré l’intervention auprès du groupe contrôle. L’utilisation du passé et de la phrase interrogative était ciblée durant l’intervention expérimentale. Des protocoles de pensée à haute voie ainsi qu’un questionnaire ont été utilisés pour mesurer la prise en compte de la rétroaction corrective. Des tâches de description d’images et d’identification des différences entre les images ont été administrées avant l’intervention (pré-test), immédiatement après l’intervention (post-test immédiat) et 8 semaines plus tard (post-test différé) afin d’évaluer les effets des différentes conditions rétroactives sur l’apprentissage des formes cibles. Un questionnaire a été administré pour identifier les perceptions des apprenants quant à la rétroaction corrective. En termes de prise en compte, les résultats indiquent que les participants sont en mesure de remarquer la rétroaction dépendamment de la forme cible (les erreurs dans l’utilisation du passé sont détectées plus que les erreurs d’utilisation de la phrase interrogative) et de la technique rétroactive utilisée (l’incitation et le mélange d’incitation et de reformulations sont plus détectés plus que la reformulation). En ce qui a trait à l’apprentissage, l’utilisation du passé en général est marquée par plus de développement que celle de la phrase interrogative, mais il n'y avait aucune différence entre les groupes. Le lien direct entre la prise en compte et l’apprentissage ne pouvait pas être explicitement établi. Pendant que la statistique inférentielle a suggéré une relation minimale entre la prise en compte du passé et son apprentissage, mais aucune relation entre la prise en compte de la phrase interrogative et son apprentissage, les analyses qualitatives ont montrés à une association entre la prise en compte et l’apprentissage (sur les deux cibles) pour certains étudiants et augmentations sans prise en compte pour d'autres. Finalement, l’analyse factorielle du questionnaire indique la présence de quatre facteurs principaux, à savoir l’importance de la rétroaction corrective, la reformulation, l’incitation et les effets affectifs de la rétroaction. Deux de ces facteurs ont un effet modérateur sur la prise en compte de la rétroaction sans, toutefois, avoir d’impact sur l’apprentissage. / This quasi-experimental study sought to investigate the often assumed yet little investigated relationship between noticing of corrective feedback (CF) and L2 development in relation to learner beliefs about error correction. Specifically, it aimed to (1) uncover the noticeability and effectiveness of three CF techniques (namely, recasts, prompts, a combination of the two) (2) to determine a relationship between noticing of CF and learning of the past tense and questions in the past, and (3) to determine whether learner beliefs about CF mediate what is noticed and learned in the language classroom. The participants were four groups of high-beginner college level francophone ESL learners (n = 99) and their teachers. Each teacher was assigned to a treatment condition that fit his CF style, but the researcher taught the controls. CF was provided to learners in response to their production problems with the simple past and questions in the past. While noticing of CF was assessed through immediate recall and questionnaire responses, learning outcomes were measured by way of picture description and spot the differences tasks administered through a pre-test, post-test, and delayed post-test design. Learner beliefs about CF were probed by means of a 40-item questionnaire. To elicit the learner and teacher perspectives on the study, semi-structured interviews were held with the three teachers and 20 learners, drawn randomly from the participating classes. The results indicated that the noticeability of CF is dependent on the grammatical target it addresses (i.e., feedback on past tense errors was noticed more) and that the feedback techniques that push learners to self-correct alone or in combination with target exemplars are more effective in bringing out the corrective intent of a feedback move. In relation to the learning outcomes, the overall past tense accuracy increased more than that for questions, but there were no differences between the groups. The direct link between noticing and learning could not be unequivocally established. While the inferential statistics suggested a minimal relationship between noticing and past tense scores, especially if the CF was provided with recasts, but no relationship between noticing and questions scores, the qualitative analyses pointed to an association between noticing and test scores (on both targets) for some learners and gains without noticing for others. Finally, in relation to the beliefs about CF, the participants’ responses centered on four common themes (the importance of oral CF, recasts as CF technique, prompts as CF technique, and affective consequences of CF), two of which mediated the noticeability of the supplied CF, but none impacted the learning outcomes.

La rétroaction corrective écrite en francisation au Québec : les techniques, les types d’erreurs et la compétence des apprenants à l’écrit

Rouleau-Girard, Élaine 04 1900 (has links)
La rétroaction corrective (RC) se définit comme étant un indice permettant à l’apprenant de savoir que son utilisation de la L2 est incorrecte (Lightbown et Spada, 2006). Les chercheurs reconnaissent de plus en plus l’importance de la RC à l’écrit (Ferris, 2010). La recherche sur la RC écrite s’est grandement concentrée sur l’évaluation des différentes techniques de RC sans pour autant commencer par comprendre comment les enseignants corrigent les textes écrits de leurs élèves et à quel point ces derniers sont en mesure d’utiliser cette RC pour réviser leurs productions écrites. Cette étude vise à décrire quelles techniques de RC sont utilisées par les enseignants de francisation ainsi que comment les étudiants incorporent cette RC dans leur révision. De plus, elle veut aussi vérifier si les pratiques des enseignants et des étudiants varient selon le type d’erreur corrigée (lexicale, syntaxique et morphologique), la technique utilisée (RC directe, indirecte, combinée) et la compétence des étudiants à l’écrit (faible ou fort). Trois classes de francisation ont participé à cette étude : 3 enseignants et 24 étudiants (12 jugés forts et 12 faibles). Les étudiants ont rédigé un texte qui a été corrigé par les enseignants selon leur méthode habituelle. Puis les étudiants ont réécrit leur texte en incorporant la RC de leur enseignant. Des entrevues ont aussi été réalisées auprès des 3 enseignants et des 24 étudiants. Les résultats indiquent l’efficacité générale de la RC à l’écrit en langue seconde. En outre, cette efficacité varie en fonction de la technique utilisée, des types d’erreurs ainsi que du niveau de l’apprenant. Cette étude démontre que ces trois variables ont un rôle à jouer et que les enseignants devraient varier leur RC lorsqu’ils corrigent. / Corrective feedback (CF) is defined as the teacher’s reaction to the learner’s production to indicate the presence of an error (Lightbown et Spada, 2006). Researchers increasingly recognize the importance of written corrective feedback (Ferris, 2006). The research on written CF is largely focused on the evaluation of various techniques of CF without previously understanding how teachers correct texts and without taking into consideration the extent to which their students are capable of using this CF to revise their written productions. This study sets out to describe which corrective feedback techniques adult French as a second language teachers use and how students incorporate this corrective feedback in their revision process. Moreover, it aims to verify if teachers and students’ practices vary according to error type (lexical, syntactic and morphological), CF technique (direct, indirect, or combined feedback) and student proficiency level (weak or strong). Three adult French as a second language classes took part in this study: 3 teachers and their respective 24 students (12 deemed strong and 12 weak). Student wrote a text which was then corrected by the teachers according to their regular CF approach. Afterwards, students rewrote their text incorporating their teacher’s corrective feedback. Interviews were conducted with the 3 teachers and their 24 students. Results indicate the overall effectiveness of written corrective feedback in second language learning. This efficacy varies depending on the CF technique used, error type and learner proficiency level. This study demonstrates that these three variables indeed play an important role and that teachers should vary their corrective feedback when reacting to their students’ written productions.

Les pratiques commerciales déloyales à l'aune des droits anglo-américains : approche comparative / The European unfair commercial practices in the light of the Anglo-American laws : comparative study

Ferreira, Christophe 04 December 2015 (has links)
Économiquement et politiquement, la société occidentale est menée par deux ensembles que sont l’Union européenne et les États-Unis d’Amérique. D’un point de vue juridique, cette distinction répond à une autre qu’est celle entre les États de tradition romano-germanique et ceux de common law. Aujourd’hui, cette distinction s’estompe tant ces deux systèmes juridiques se confondent. Sur la forme d’abord, les droits de common law recourent de manière croissante aux droits statutaires, et inversement les droits continentaux laissent une place grandissante à la jurisprudence et notamment à celle de la Cour de Justice de l’Union européenne. Sur le fond ensuite, ces deux systèmes juridiques et leurs pendants économiques s’unifient autour d’une économie de marché qu’ils souhaitent protéger des comportements nuisibles aux consommateurs, aux concurrents, et donc in fine au marché lui-même. Or, cette protection nécessite, notamment, d’imposer une loyauté lors de l’emploi de pratiques commerciales par des professionnels vis-à-vis de consommateurs.C’est pourquoi, le 11 mai 2005, a été promulguée une directive relative aux pratiques commerciales déloyales des entreprises vis-à-vis des consommateurs qui harmonise de façon maximale la qualification de ces pratiques sans traiter de leur régime juridique. Dès lors, il semble nécessaire de comparer les systèmes européen et anglo-américain, notamment par la considération de la théorie des economic torts, afin d’étudier si ces derniers pourraient s’enrichir l’un de l’autre. Il sera ainsi démontré que si la qualification poursuit les mêmes raisonnements, la réaction face à de tels comportements est quant à elle plus nuancée. / Economically and politically, the Western society is led by two main sets which are the European Union and the United States of America. Juridically, this distinction matches with a more general one wich can be observed between traditional romano-germanic states and those submitted to the common law. Nowadays, this distinction tend towards disappearance because of the intermingling of these two legal systems. Indeed, regarding the form first, common law states resort more and more to statutory laws, and conversely, traditional romano-germanic laws leave a growing room for the case law, and especially, for the jurisprudence of the European Court of Justice. In substance then, because those two legal systems correspond to two economic systems unified around a market economy. They want to protect it against damaging behaviours for consumers, competitors, and in fine for the market itself But this protection require in particular to order fairness during the use of business-to-consumer commercial practices. That is why, the European Parliament and the Council, announced a directive concerning unfair business-to-consumer commercial practices in the internal market, which contains maximum harmonisation provisions about unfair commercial practices, but without provisions about their juridical regime. Then, it seems necessary to compare the European system with the American one, especialy with the consideration of the theory of the economic torts, in order to study if these two can enrich each other. So, it will be demonstrated that if the classification follows the same arguments on either side of the Atlantic, the responses to those behaviours is more contrasted.

Les croyances des enseignants et des apprenants adultes quant à la rétroaction corrective à l’oral et la pratique réelle en classe de français langue étrangère en Égypte

Mohamed Hassan Mohamed, Rania 01 1900 (has links)
Différentes études ont montré que le niveau des futurs enseignants, issus des écoles publiques, en français langue étrangère (FLE) en Égypte est assez faible. Ceux-ci font un grand nombre d’erreurs répétitives à l’oral. Quoique ce manque de précision langagière puisse être dû à plusieurs facteurs, il appert que la rétroaction soit une des variables contribuant à ce phénomène (comme le nombre d’étudiants en classe, la durée du cours, l’âge et la motivation des étudiants, les méthodes d’enseignement, etc.). La rétroaction corrective est généralement définie comme toute correction explicite ou implicite de la part de l’enseignant indiquant que la production de l’apprenant est erronée. Elle est considérée comme indispensable dans les classes de langues secondes (LS) (Shmidt, 1983, 2001 ; Long, 1991, 1996 ; Lightbown, 1998). Pour ces raisons, cette étude porte sur la rétroaction corrective et, plus spécifiquement, sur les croyances des enseignants et des apprenants quant à celle-ci, ainsi qu’à son utilisation dans les classes de FLE en Égypte. Les recherches antérieures indiquent que les croyances des enseignants quant à l’acte d’enseigner influencent leurs pratiques en classe, que les croyances des apprenants influencent leur motivation, leur niveau et leurs efforts déployés pour l’apprentissage de la langue, et qu’une divergence entre les croyances des professeurs et celles des apprenants peut entraîner des effets négatifs sur l’apprentissage de la langue cible, ce qui indique ainsi qu’il est de grande importance d’explorer les croyances. Ainsi, la présente étude vise à explorer les croyances des professeurs égyptiens et celles de leurs étudiants en ce qui a trait à la rétroaction corrective à l’oral, la différence entre ces croyances, et l’identification des pratiques réelles des professeurs afin de décrire à quel point celles-ci reflètent les croyances exprimées. Pour ce faire, un questionnaire a été administré à 175 étudiants et 25 professeurs appartenant à trois universités égyptiennes afin de déterminer leurs croyances déclarées. Des entrevues semi-dirigées et des observations directes ont été réalisées auprès de neuf des 25 professeurs participants pour mieux déterminer leurs croyances et leurs pratiques rétroactives. Les résultats obtenus ont révélé qu’il existe des divergences importantes entre les croyances des professeurs et celles des étudiants, d’un côté, et entre les croyances des professeurs et leur pratique, de l’autre côté. Par exemple, la plupart des étudiants ont déclaré leur opposition à l’utilisation de la reformulation alors que presque la moitié des professeurs ont indiqué être en faveur de cette même technique. Les professeurs ont indiqué que leur choix de techniques rétroactives dépend du type d’erreurs et qu’ils préfèrent inciter les apprenants à s’auto corriger. Cependant, ces mêmes professeurs ont utilisé la reformulation pour corriger la majorité des erreurs de leurs apprenants, quelle que soit leur nature. Nous parvenons ainsi à la conclusion que l’utilisation de la reformulation, qui fait l’objet d’une divergence au niveau des croyances, pourrait être à l’origine du manque de précision langagière rapporté par les chercheurs. / Previous research revealed that Egyptian learners of French as a foreign language who will be the future teachers of French in Egypt produce numerous errors repetitively during oral productions. While this lack of accuracy can be attributed to a cohort of factors (number of students in class, duration of course, age and motivation of students, methods of teaching, etc.), it is assumed in the present study that corrective feedback could be at the origins of the reported results. Defined as implicit or explicit teacher reactions to the learners’ incorrect renditions, corrective feedback is seen by many second language acquisition researchers (Schmidt, 1983, 2001; Long, 1991, 1996; Lightbown, 1998) as a driving force behind interlanguage development. Among other things, corrective feedback draws learners’ attention to form and helps them notice the gap between their interlanguage and the L2 norm. In light of these theoretical arguments along with empirical research findings indicating the benefits of corrective feedback, the present study investigated corrective feedback provided in French as a foreign language classes in Egyptian universities. More specifically, the study explored teachers’ and students’ beliefs about feedback as well as teachers’ in-class use of feedback. Previous research on beliefs indicates that teachers’ beliefs shape their teaching and that learners’ beliefs affect their motivation and determine the effort students are willing to deploy to learn the target language. Based on these theoretical and empirical claims, the present study investigated teachers’ and students’ beliefs about oral corrective feedback in learning French as a foreign language in Egypt and explored teachers’ actual corrective feedback practices to determine the extent to which they correspond to their declared beliefs. A beliefs questionnaire was administered to 175 students and 25 language teachers to determine their beliefs about corrective feedback. Nine of the 25 teachers were also interviewed and observed for a total of 27 hours to further investigate their beliefs and in-class practices. The results indicate a mismatch between teachers’ and students’ beliefs on the one hand, and a divergence between teachers’ beliefs and their actual teaching on the other. In terms of the relationship between students’ and teachers’ beliefs, the results reveal that while the majority of the learners do not see recasts as an effective feedback technique, almost half of the teachers do. As for the mismatch between teachers’ beliefs and their in-class practices, a two-fold pattern emerged. First, all the teachers reported that error type determined the technique they used to correct errors and that they preferred to push their learners to self-correct. However, recasts proved to be the technique of choice and that was regardless of error type. Instances of self-correction were rare with teachers choosing to recast most of their students’ errors instead of pushing them to remedy the errors on their own. As such, it may be speculated that the teachers’ choice of corrective feedback techniques, which happens to run counter to the students’ expectations (as shown in the beliefs questionnaire) may be a major factor behind the students’ reported lack of accuracy

Noticeability of corrective feedback, L2 development and learner beliefs
