The present inquiry sets out to explore the self as an expatriate eacher working in international schools, through the lens of ositioning. To better understand complex phenomena such as the self and its episodic encounters in the social arena, this study uses positioning theory as an analytical framework. The self is followed as it moves from its private sphere to the social milieu where it takes on its multiplicity, as a social being. The dynamics of positioning is illustrated by the mutually determined triad. Hence, the self is looked at in one of its main social engagements: the recruitment where the social episode is mutually framed by the storylines of the participants, the social force and the position taken on. Illustrations are given to exemplify and extend the use of positioning theory in an international school context. The implications brought up by the results of the present inquiry are applicable not only to the expatriate teacher but also to the wider expatriate community.

O clima apresenta uma importância indiscutível, constituindo-se num dos mais relevantes elementos da biosfera, desta forma imprescindível o conhecimento minucioso de sua dinâmica, bem como de sua interação com os outros elementos do ambiente. Optou-se pelo estudo de uma \"bacia hidrográfica\" pelas facilidades de análise que a mesma oferece, pois por se tratar de uma unidade bem delimitada, todos os processos geológicos, geomorfológicos, hidrológicos, pedológicos, climatológicos, entre outros, ocorrem, em seu limite natural. Para tanto, selecionou-se a Bacia do Ribeirão do Lobo, por apresentar uma consistência de dados meteorológicos fundamentais para este estudo, e por abranger uma área de foco de muitas pesquisas em diversas áreas do conhecimento. Assim, uma das metas desta pesquisa foi apresentar informações climatológicas que subsidiarão a compreensão dos fenômenos interligados em outras áreas. A concepção climática elaborada por SORRE (1951) e na análise rítmica preconizada por MONTEIRO (1971) foram os conceitos norteadores desta pesquisa, entretanto, numa primeira etapa efetuou-se uma abordagem climática tradicional, utilizando-se de estatística e de computação, para definir as tendências ao longo da referida bacia hidrográfica. Assim, sob a temática do clima, foram analisados quatro episódios representativos, descrevendo o comportamento da circulação atmosférica e as repercussões nos elementos climáticos. / The climate presents an unquestionable importance, being constituted in one of the most important elements of the biosphere, thus becoming indispensable the meticulous knowledge of its dynamics, as well as its interaction with the other elements ofthe atmosphere. The study of a hydrographic basin was opted due to its easiness of analysis therefore for being a well delimited physical unit, all the geological processes, geomorphologic, hidrologic, pedologic, climatological, amog others, occur in its natural boundary. For this purpose, the Wolf River System was selected, by presenting a consistence of fundamental meteorological data for this study, and for comprising a focus area of many researches in several areas of knowledge. Thus, one of the goals of this research was to present climatological information that will subsidize the understanding of the interlinked phenomena in other areas. The climactic conception elaborated by SORRE (1951) and in the rhythmic analysis extolled by MONTEIRO (1971) were the guideline of this research, however, in a first stage it occurred a traditional climactic approach, making use of the statistics and of the computation, to define the tendencies along referred hydrographic basin. So, under the optics dynamics of the climate, four representative episodes were analyzed, describing the behavior of the atmospheric circulation and the repercussions in the climactic elements.

This study contributes to an understanding of how coherence can be assigned or constructed by participants in authentic multiparty conversational interaction. Coherence is analysed as a type of organisation relevant for the making of meaning in situated interaction, but also in retrospect from a third party's (or analyst's) perspective; it is both constructed and reconstructed. Important questions are: what makes multiparty talk hold together, what do a number of participants in conversation (have to) do in order to sustain coherence, and in what senses can multiparty conversations be argued to be coherent? A notion of episode is (re)introduced as a unit of natural social interaction, manifest at a structurally intermediate, or a global. level of conversation. The use of episode implies that coherence, a pragmatic phenomenon, steadily encompasses text, i.e. talk, context(s) and actions, and sense-making practices invoking contexts during the progression of interaction. This reflects the reciprocal relations between länguage, social interaction, and cognition. Also, a coding method of coherence has been developed, Topical Episode Analysis (abbreviated as TEA). The thesis explores the concept of episode and its place among units of interaction, and describes the episode structure and coherence-making in some specific activity types. The empirical material used, 24 multiparty conversations making up a total of 1500 episodes, consists of dinner conversations among peers, multi-generational family gatherings (involving aphasics), radio talk shows, and conversations recorded at a centre aimed for elderly people (with symptoms of dementia). In all conversations, conversing is a main activity. Both qualitative and quantitative analyses have been carried out. Results include the following points: (i) coherence in multiparty conversation can be regarded as a co-construction; (ii) coherence is accomplished through the invoking of contexts (cotext, situation, and background knowledge), implying that coherence is an attribute of activities in context and not only 'text'; (iii) coherence-making is the unmarked case in authentic conversation and incoherence or non-coherence appear to be theoretical constructs; (iv) coherence patterns are activityspecific; (v) coherence is multilayered, consisting of one local and several global levels; (vi) coherence is constructed through a division of communicative labour, suggesting that also people with communicative impairments contribute to coherence-making.

Data mining is the process of extracting patterns from huge data. One of the branches in data mining is mining sequence data and here the data can be viewed as a sequence of events and each event has an associated time of occurrence. Sequence data is modelled using episodes and events are included in episodes. The aim of this thesis work is analysing architecture simulation output data by applying episode mining techniques, showing the previously known relationships between the events in architecture and providing an environment to predict the performance of a program in an architecture before executing the codes. One of the most important points here is the application area of episode mining techniques. Architecture simulation data is a new domain to apply these techniques and by using the results of these techniques making predictions about the performance of programs in an architecture before execution can be considered as a new approach. For this purpose, by implementing three episode mining techniques which are WINEPI approach, non-overlapping occurrence based approach and MINEPI approach a data mining tool has been developed. This tool has three main components. These are data pre-processor, episode miner and output analyser.

Emotions are the very heart of people's experiences. Moreover, emotions determine people's focus because they influences people's interests and define dimensions of people's worlds across cultures. However, past research on emotions has argued about the meaning of basic emotions being relative or universal cross cultures. It seems as if researchers are avoiding the issues regarding the meaning of negative and positive emotions and how these emotions are expressed within a cross–cultural context. One of the biggest concerns is that if the descriptions of people's positive and negative emotions are not understood, it becomes difficult for people from different cultural backgrounds to maintain healthy relationships and relate their emotions with one another. Apart from the lack of research regarding the meaning of emotions across cultures, emotion and emotion experiences in the extrinsic and intrinsic level to the employee, especially within the cross cultural context, is also an under researched topic in South African organisations. The reason for this is that organisations view emotions as a complicated subject to understand and tend to focus more on maintaining positive emotions at work rather than creating a stable emotional climate in an organisation for employees. The lack of creating a stable emotional climate within an organisation and addressing adverse discrete emotions and emotional experiences could have harmful effects on employees' mental health and physical well–being. Furthermore, the absence of measuring instruments to investigate the emotions and emotional experiences of employees may result into experiencing painful personal incidents, lack of pride in one's accomplishments, lack of engagement and commitment, negative behaviour and attitudes, and intentions to quit. These experiences might trigger any negative emotions such as anger, hate, irritation, disappointment, despair and frustrations. The above problem statement gave a reason to investigate whether the meaning of emotions differs across cultures or is the same cross culturally, to identify the meaning structure of emotions and to identify the emotions and emotion experience of the employees within the work environment's extrinsic and intrinsic level experience to the individual. Therefore, the Componential Emotions Theory was a relevant theory to determine the meaning of emotions within the Tswana speaking group. The theory of determining emotions and emotion episodes by the Affective Events Theory was followed as a way of determining emotions and emotion experiences comprehensively in the Setswana speaking language group. The Componential Emotion Theory was adapted to provide a clarification of how people across cultures describe their emotion terms. According to the Componential Emotion Theory, emotion terms across cultures can be described through cognitive appraisal, subjective feelings, facial expressions, verbal expressions, gesture, bodily sensations, action tendencies and emotion regulation. Regarding the Affective Events Theory (AET), the theory suggests that emotion episodes at work can cause or be generated by either positive or negative emotions at work. The theory represents an understanding of how employees emotionally respond to certain emotion episodes that occur in various organisational settings. The following research objectives were formulated based on the above–mentioned description of the research problem. The research objectives were addressed into two research articles where study 1 (the meaning of emotion) was the first research article and study 2 (studying the emotion episodes and associated emotions) was the second research article. The objectives of study 1 were to determine the meaning of emotions as conceptualised in a literature review with specific reference to emotion dimensions; to determine how emotions and culture are conceptualised in a literature review with specific reference to the Setswana language group; to describe the Componential Emotion Theory in the literature as an approach to study the meaning of emotion in cultural contexts; to determine if the 24 emotion terms as measured by the Grid instrument, will refer to all components by revealing the meaning of an emotion structure in Setswana; to determine if the Meaning Grid will display acceptable alpha coefficients when compared with internationally studies having a value of 0, 80 and higher; to determine if the meaning of emotion (as measured in the context of the Componential Emotion Theory approach) in a Setswana–speaking students sample will include the evaluation–pleasantness dimension; to determine if the meaning of emotion (as measured in the context of the Componential Emotion Theory approach) in a Setswana–speaking students sample will include the potency–control dimension; to determine if the meaning of emotion (as measured in the context of the Componential Emotion Theory approach) in a Setswana–speaking students sample will include the activation–arousal dimension; to determine if the meaning of emotion (as measured in the context of the Componential Emotion Theory approach) in a Setswana–speaking students sample will include the unpredictability dimension; and to draw conclusions and suggest future research about the meaning of emotion in the Setswana language group. In this part of the study, the sample consisted of (N=122) and was taken from a higher education institution in the North–West Province. A Setswana translated version of the shortened form of the Meaning Grid instrument was administered. Four pilot studies were conducted (Meaning Grid) which consisted of (N=28) and the data gathering was held in a higher education institution in the North West Province. After all four pilot studies had been conducted, the shortened form of the GRID (Translated in Setswana) was then administered using the paper and pencil method (61 emotion features). Furthermore, by utilising the SPSS program, Principal Component Analysis (PCA) was executed to determine the number of factors and indicate the emotion dimensions present in the Setswana language group. In terms of inter–rater reliability, the cronbach–alpha for each respondent was calculated on their rating of emotion terms. A cut–off point for each item – total correlations of at least 0,20 – was used for inclusion for the final determination of reliability. In essence, it means that unreliable raters were dropped in order to keep the reliability high. The Componential Emotion Theory of Scherer (1987) was applied and indicated a four–factor model that should first be extracted namely: evaluation–pleasantness, activation–arousal, potency–control and unpredictability. However, examination of a three and four factorial extraction was not interpretable. The two emotion words, namely sadness and shame, were eliminated because they were outliers in the rotations done. Further inspection of the Scree–plot indicated that a two factor solution should be extracted. A principal component analysis (PCA) (done on the mean corrected scores) were therefore computed for two factors after a varimax rotation - which was interpretable as Evaluation–pleasantness and potency–control dimensions. The results and the interpretation of the two components (dimensions) are based on their relationship with the 61 emotion features. A further analysis was done to determine the component loadings of the 24 Grid emotion term on each factor. This gave an indication of the position of the emotion terms on the specific factors (evaluation–pleasantness and potencycontrol dimensions). Furthermore, the positions of each emotion term in relation with other emotions were graphically represented in a scatter plot. The objectives of study 2 were to conceptualise emotions at work as from a literature research; To determine the relevance of discrete emotions, emotion episodes and the use of the Affective Events Theory for the work context as presented in the research literature; to determine emotion episodes that are experienced in the workplace by Setswana employees; to determine emotion episodes and associated emotions reported on an extrinsic level of Setswana speaking working adults; to determine emotion episodes and associated emotions reported on an intrinsic level of Setswana speaking working adults; and to draw conclusions and make suggestions for future research about the emotion episodes and related emotions of Setswana employees. Within this part of the study a non–probability availability sample (N= 120) was taken from the mining industry, tourism industry, and community services including the government, manufacturing, agriculture, construction and the infrastructure industry. A pilot study was utilised as a prerequisite for the successful execution, and completion of this research study allowed the researcher to acquire thorough background knowledge about specific problems that the researcher intended to investigate. Thereafter, the Tswana employees understood the questions and could report without effort on emotion episodes at work that they experienced. Data collection was done through the Episode Grid, and two questions on emotion episodes were used for collecting emotion episodes in Setswana namely: the participants had to report their most intense emotion episode that they have experienced within their workplace in detail, for example, what happened? How did the episode begin? How did it evolve? How did it end? Secondly, the participants were asked to describe the three most important emotions or feelings that were experienced in the particular event. The described episodes were then categorised into different categories on intrinsic and extrinsic level experienced to the individual. Furthermore, the specific episodes were divided into two types of category levels namely extrinsic emotion episodes and intrinsic emotion episodes. The categories that were found on the extrinsic level concerning emotion episodes at work were acts of management, acts of colleagues, company procedure/company policy, acts of customers, work procedure, external environment and acts of subordinates. Concerning the intrinsic level about emotion episodes at work, the categories that were found included task problems/making mistakes, personal incidents, goal achievement, receiving recognition, physical incidents, discrimination, workload and lack of control. The emotions that were experienced on the extrinsic level comprised emotion terms such as anger, disappointment, anxiety, hurt, irritation, disgust, annoyance, fear, sadness, despair, worry, frustration, embarrassment, shame, hate, stress and anxiety. Regarding the emotions experienced on the intrinsic level, the emotion terms that were described included anger, disappointment, anxiety, hurt irritation, fear, sadness, despair, frustration, hate, pride, stress, compassion, guilt and happiness. Recommendations for the organisation and future research were made. / Thesis (M.Com. (Human Resource Management))--North-West University, Potchefstroom Campus, 2011.

Cette thèse présente une méthode de pronostic basée sur des règles symboliques extraites par fouille de données. Une application de cette méthode au cas du grippage de pompes à vide est aussi détaillée. Plus précisément, à partir d'un historique de données vibratoires, nous modélisons le comportement des pompes par extraction d'un type particulier de règles d'épisode appelé « First Local Maximum episode rules » (FLM-règles). L'algorithme utilisé pour extraire ces FLM-règles extrait aussi de manière automatique leur fenêtre optimale respective, i.e. la fenêtre dans laquelle la probabilité d'observer la prémisse et la conclusion de la règle est maximale. Un sous-ensemble de ces FLM-règles est ensuite sélectionné pour prédire les grippages à partir d'un flux de données vibratoires. Notre contribution porte sur la sélection des FLM-règles les plus fiables, la recherche de ces FLM-règles dans un flux continu de données vibratoires et la construction d'un intervalle de pronostic de grippage à partir des fenêtres optimales des FLM-règles retrouvées. / This thesis presents a symbolic rule-based method that addresses system prognosis. It also details a successful application to complex vacuum pumping systems. More precisely, using historical vibratory data, we first model the behavior of the pumps by extracting a given type of episode rules, namely the First Local Maximum episode rules (FLM-rules). The algorithm that extracts FLM-rules also determines automatically their respective optimal temporal window, i.e. the temporal window in which the probability of observing the premiss and the conclusion of a rule is maximum. A subset of the extracted FLM-rules is then selected in order to further predict pumping system failures in a vibratory data stream context. Our contribution consists in selecting the most reliable FLM-rules, continuously matching them in a data stream of vibratory data and building a forecast time interval using the optimal temporal windows of the FLM-rules that have been matched.

Assim, amparado nos pressupostos teórico-metodológicos da perspectiva histórico-cultural, na qual a singularidade é entendida como um produto da história das condições sociais e materiais do indivíduo, esse estudo tem por objetivo compreender, por meio do método do materialismo histórico dialético, a construção da identidade de adolescentes autores de atos infracionais e o papel da escola nesse processo. Trata-se, portanto, de um estudo qualitativo, que se utilizou de três principais fontes de coletas de dados, quais sejam: os registros dos Livros de Ocorrência Escolares (LOE) das escolas, os processos judiciais disponibilizados pela Vara da Infância e Juventude, bem como as entrevistas semi-estruturadas com os adolescentes. A análise dos dados, por sua vez, foi feita a partir de núcleos de significação apreendidos nos discursos dos adolescentes, em conjunto com a análise documental de dados já coletados por uma pesquisa maior, da qual o presente estudo faz parte. Os dados da pesquisa demonstraram que a escola é um lugar, para maioria destes adolescentes, de reposição de identidade estigmatizada, que sitentiza, antes do ato infracional, na figura do aluno problema e após o ato na figura de aluno infrator. Outras possibilidades de identidades com sentido emancipador lhes são, muitas vezes, negadas. Isso demonstra, portanto, o importante papel mediador da escola na constituição da identidade dos adolescentes autores de atos infracionais, tanto no sentido de repor identidades estigmatizadas por meio de preconceitos e estigmas, como de possibilitar identidades emancipadoras, de maneira a transformar e ressignificar suas trajetórias escolares negativas. / The school, as a space of socialization and transmission of historically accumulated knowledge, assumes an important role in the construction of the identity of the adolescent, both as regards the replacement of stigmatized identities, as in the possibilities of resignification with an emancipatory sense. Thus, based on the theoretical-methodological assumptions of the historical-cultural perspective, in which the singularity is understood as a product of the history of the social and material conditions of the individual, this study aims to understand, through the method of dialectical historical materialism, the construction of the identity of adolescents responsible for delinquency episodes and the role of the school in this process. It is therefore a qualitative study that used three main sources of data collection, namely: the records of School Occurrences Books (LOE) of the schools, the judicial processes made available by the Child and Youth Court, as well as semi-structured interviews with adolescents. Data analysis was based on clusters of meaning seized in the discourses of adolescents, together with the documentary analysis of data already collected by a larger research, of which the present study is part. The research data showed that the school is a place, for most of these adolescents, to replace stigmatized identity, which situates, before the infraction act, the figure of the “problem student” - and after the act - in the figure of the “offender student”. Other possibilities of identities with an emancipatory sense are often denied to them. This demonstrates, therefore, the important mediating role of the school in the constitution of the identity of the adolescents responsible for infractions, both in the sense of restoring stigmatized identities through stigma and prejudice, and of enabling emancipatory identities that transform and resignify their negative school trajectories.
