Sloutsky (2010; Kloos與Sloutsky, 2008) 操弄不同的類別結構亂度 (categorical entropy) 進行類別學習作業，藉此提出了雙系統理論，認為人們會啟動不同的系統，濃縮式系統 (compression-based system)或選擇式系統 (selection-based system)，以適應不同的類別結構組成之刺激材料。本研究回顧了Sloutsky的研究證據與過去類別學習領域的相關文獻，認為此雙系統理論可能只適用在向度數目較多的情境之下，因此設計了三個實驗，使用和Kloos與Sloutsky (2008) 相同的實驗派典，欲說明刺激材料的向度個數確實會影響到人們的類別學習行為。實驗一發現，Sloutsky所預測的類別結構與學習方式之交互作用只出現在向度個數較多的情境，向度個數少時則無此交互作用。實驗二得到與實驗一相同的結果，並排除了刺激材料本身特性（幾何圖形或類自然類別材料）此一混淆變項。實驗三採用特別設計的依變項，直接觀察受試者採用相似性(similarity)或規則(rule)的方式進行分類判斷，集群分析的結果顯示在向度數目少的情境時，不管何種類別結構受試者均傾向使用以規則為基礎的選擇式系統學習。因此，綜合以上發現，本研究認為Sloutsky的雙系統理論必須考慮到向度數目此一變項，才能更廣泛的應用於各種類別學習情境之中。 / The goal of this research is to point out that the dimensions of experimental materials can influence human category learning, which is neglected by traditional models of category learning. Three experiments in this research examined the effect of stimuli complexity by following the paradigms of Kloos and Sloutsky (2008). In Experiment 1, the prediction of Sloutsky’s theory (2010) on the interaction effect between category structures and learning conditions succeeds only at high complexity of materials, but fails in the low complexity condition. Experiment 2 was conducted by the same experimental setting as Experiment 1, but the natural-like stimuli were replaced by well-defined artificial geometrics. The result of Experiment 2 is the same as Experiment 1, suggesting that the complexity of materials plays a critical role in category learning no matter what kind of stimuli are used. Experiment 3 found that various materials complexity had distinct effects on human category representations. Namely, when experimental stimuli are relatively complex, people would use the corresponding category learning system to represent stimuli to learn dense categories or sparse ones. In contrast, when the stimuli are relatively simple, participants would represent the stimuli in a rule-based manner both in dense and sparse category structures.

This thesis examines how women perform as leaders within male-dominated professions, including law, business, politics, the military, and the academy. In studying women's performances in terms of the corporeal and spectacular, the investigation seeks to understand how particular women enact leadership through their materiality within specific times and places. Drawing on Gilles Deleuze and Felix Guattari's (1988) theorising of the processes of 'becoming', woman-as-leader is studied as an entity that passes from one incomplete and multiple assemblage to another, rather than as a singular 'developing' identity. The research is located within and between the paradoxes that complicate the performances of leadership for women. One key paradox serving as a rationale for this investigation is that, while 'equity' has become a truism of contemporary leadership, it is clear from formal reports (for example, the 2002 Equal Opportunity for Women in the Workplace Agency (EOWA) report), that many women continue to be marginalised and under-represented as leaders and senior managers. Moreover, those few women who have achieved success often acknowledge themselves as both legitimately and differently - and sometimes awkwardly, located as leaders in the everyday enactments of their work. The investigation of leadership within and between such paradoxes is problematic for a neo-liberal order of thinking, and even for socially critical theory, because of the assumptions that modernist literature makes about women's struggle for political legitimacy (ie, a narrative of progress, emancipation, and/or linear cumulative historical development). It is for this reason that the conceptual tools used in this study are drawn from post-feminist and post-structuralist theory. Such theorising refuses literal categories in favour of 'ironic categories' (Rorty, 1989) where two apparently oppositional ideas are understood to be both necessary and true. To explore women 'becoming' leaders (Deleuze & Guattari, 1988), 'woman-as-leader' is interrogated using Jean François Lyotard's (1984) notion of 'performativity,' Mary Russo's (1994) theorising of the embodied spectacle of 'the female grotesque', and Richard Rorty (1989) and Donna Haraway's (1991) insistence on partiality, doubt, and the importance of 'undoing' the fixity of modernist categories - in this instance, for women. One ironic category of importance to the study is Haraway's theorising of a 'cyborgian identity', a technological assemblage that is part-human/part-machine. This allows acknowledgement that women leaders inhabit realms beyond the boundaries imposed by the same/difference, human/machine, present/past, and real/virtue binaries. Using these tools, the performances of a number of women leaders is examined in an empirical study that focuses on a few individual women located in male-defined and male dominated settings. The empirical work has two key components. First, it provides a reading of three moments in time where a female individual dys-appears (Leder, 1990) in the public gaze, erupting as a unique spectacle in spaces that are both enabling and constraining. It foregrounds the unique complexities of three public performances in which women made a spectacle of themselves, while the analysis refuses to either celebrate the individuals involved, or to bemoan the conditions under which they did so. The analysis demonstrates the value of re-thinking leadership in terms of its complexity for the female as embodied public 'performer'. It then moves on to focus specifically on the (embodied, spectacular) tactics being deployed by women leaders in contemporary professional work. This analysis is located in the professions of law, business, politics, the military, and the academy. The data-as-evidence emerging from the analysis show women leaders to be both and neither enacting and troubling 'proper' (ie, traditional and/or known) leadership conventions. The analysis provides a reading of how, through certain tactical shifts, women work to 'de-territorialise' both the 'forms of content' and 'forms of expression' (Deleuze & Guattari, 1988) constituting leadership performances. It makes visible the tactical assemblages these women deploy, and the ways in which such tactics separate, combine, and compound the same/difference, equality/inequality, either/or binaries. The specific tactical manoeuvres for achieving legitimacy in the public gaze cluster around four identifiable ironic categories: (i) legitimate cross-dressing (ii) assertive defence (iii) proper blasphemy, and (iv) humanly-machinic. When taken together, the two components of the empirical study compel a re-theorising of 'woman-as-leader' as both insider and outsider, an entity engaging in the on-going work of diss-assembling and re-assembling a leaderly self. Woman is shown 'to be not one, not multiple, but multiplicities', simultaneously (Deleuze & Guattari, 1988). This re-theorising provides a more nuanced account of women leaders working to maintain legitimacy, credibility, and propriety as leaders than mainstream theorising of leadership and management currently allows.

Young children’s peer interactions involve their use of interactional resources to organise, manage and participate in their social worlds. Investigation of children’s employment of interactional resources highlights how children participate in peer interaction and their social orders, providing insight into their active construction and management of their social worlds. Frequently, these interactions are described by adults as ‘play’. The term play is often used to describe children’s activities in early childhood education, and constructed in three main ways: as educative, as enjoyable, and as an activity of children. Play in educational settings is often constructed, and informed by, adult agendas such as learning and is often part of the educational routine. This study shows how children work with a different set of agendas to those routinely ascribed by adults, as they actively engage with local education orders, and use play for their own purposes as they construct their own social orders. By examining children’s peer interactions, and not describing these activities as play, the focus becomes the construction and organisation of their social worlds. In so doing, this study investigates some interactional resources that children draw upon to manage their social orders and organise their peer interactions. This study was conducted within an Australian, non-government elementary school. The participants were children in a preparatory year classroom (children aged 4 – 6 years). Over a one month period, children’s naturally occurring peer interactions within ‘free play’ were video-recorded. Selected video-recorded episodes were transcribed and analysed, using the approaches of ethnomethodology, conversation analysis and membership categorization analysis. These methodologies focus on everyday, naturalistic data, examining how participants orient to and produce social action. The focus is on the members’ perspectives, that of the children themselves, as they interact. Ethnomethodology, conversation analysis and membership categorization analysis allow for in-depth examination of talk and action, and are used in this study to provide a detailed account of the children’s interactional strategies. Analysis focused on features of children’s situated peer interaction, identifying three interactional resources upon which the children drew as they constructed, maintained, and transformed their social orders. The interactional resources included: justification; category work, in particular the category of mother; and the pretend formulation of place. The children used these interactional resources as a means of managing peer participation within interactions. First, the children used justification to provide reasons for their actions and to support their positions. Justifications built and reinforced individual children’s status, contributing to the social organisation of their peer group. Second, the children negotiated and oriented to categories within the pretend frame of ‘families’. The children’s talk and actions jointly-constructed the mother category as authoritative, enabling the child, within the category of mother, to effectively organise the interaction. Third, pretense was used by the children to negotiate and describe places, thus enabling them to effectively manage peer activity within these places. For a successful formulation of a place as something other than it actually was, the children had to work to produce shared understandings of the place. Examining instances of pretense demonstrated the highly collaborative nature of the children’s peer interactions. The study contributes to sociological understandings of childhood. By analysing situated episodes of children’s peer interaction, this study contributes empirical work to the sociology of childhood and insight into the interactional work of children organising their social worlds. It does this by closely analysing social interactions, as they unfold, among children. This study also makes a methodological contribution, using ethnomethodology, conversation analysis, and membership categorization analysis in conjunction to analyse children’s peer interactions in an early childhood setting. In so doing, the study provides alternative ways for educators to understand children’s interactions. For example, adult educational agendas, such as the educative value of play, can be applied to examine children’s family play, highlighting the learning opportunities provided through pretend role play, or indicating children’s understanding of adult roles. Alternatively, the children’s interaction could be subjected to fine-grained analysis to explicate how children construct shared understandings of the category of mother and use it to organise their interaction. Rather than examining the interaction to discern what children are learning, the interaction is examined with a focus on how children are accomplishing everyday social practices. Close analysis of children’s everyday peer interaction enables the complex interactional work of managing, and participating in, social order within an early childhood setting to be explicated. This offers educators insight into children’s social worlds, described not as play, but as the construction and negotiation of social order.

In this context, this study aimed to analyze the trophic interactions existing between the species Geophagus brasiliensis (Quoy & Gaimard, 1824) (Osteichthyes, Cichlidae), and benthic macroinvertebrate community in three reservoirs (Monjolinho Reservoir, Fazzari Reservoir, Broa Reservoir) in order to know its feeding mode, whether there is food selectivity or preference and which would be the most suitable trophic category for the species. Benthic macroinvertebrate communities in sediments sampled simultaneously to G. brasiliensis population were analysed and experiments were carried out in order to know the feeding mode of the species. Biometric measurements for ecomorphological analyses and analysis of stomach contents of the fishes were performed and based on qualitative and quantitative analyses of the macroinvertebrates consumed and their availability in the environment the values for the selectivity index of Paloheimo were calculated for the reservoirs sampled. The results showed that benthic macroinvertebrates are often used as food resource by the populations of G. brasiliensis with great participation in its diet, allowing us to characterize this species as a benthivore. Also, it was observed that G. brasiliensis has food preference for Chironomidae larvae. / Os estudos sobre as interações tróficas entre populações nas comunidades aquáticas são fundamentais por fornecerem informações relevantes para o entendimento dos caminhos do fluxo de energia e de matéria nos ecossistemas e subsidiar a formulação de modelos sobre teias tróficas. A ocorrência de dietas flexíveis é uma característica marcante de muitas espécies da ictiofauna fluvial tropical, onde uma mesma espécie pode alternar a exploração de itens alimentares em função das variações na disponibilidade relativa do recurso alimentar motivadas por alterações temporais, espaciais e ou ontogênicas. Neste contexto, este trabalho teve por objetivo analisar as interações tróficas existentes entre a espécie Geophagus brasiliensis (Quoy & Gaimard, 1824) (Osteichthyes, Cichlidae) e a comunidade de macroinvertebrados bentônicos em três represas (Represa do Monjolinho, Represa do Fazzari e Represa do Broa), a fim de avaliar seu modo de alimentação, verificar se existe seletividade ou preferência alimentar e em que categoria trófica esta espécie melhor se enquadra. Foi analisada a composição dos macroinvertebrados bentônicos em sedimentos coletados simultaneamente as amostragens das populações de G. brasiliensis, e foram realizados experimentos em laboratório para verificar o modo como a espécie se alimenta. Medidas biométricas para caracterização ecomorfológica e análises do conteúdo estomacal dos peixes foram feitas e com base nas análises qualitativas e quantitativas dos macroinvertebrados consumidos e sua disponibilidade no ambiente foram calculados os valores do índice de seletividade de Paloheimo para os reservatórios amostrados. Os resultados mostraram que os macroinvertebrados bentônicos são frequentemente utilizados como recurso alimentar pelas populações de G. brasiliensis, tendo grande participação em sua dieta, o que poderia caracterizá-la como uma espécie bentívora. Observou-se também que G. brasiliensis tem preferência alimentar por larvas de Chironomidae.

Ce travail porte sur la catégorie d’action publique « jeunes en errance ». Il vise à comprendre son impact sur la mise en œuvre de l’action publique sur le terrain au travers de l’analyse des usages qu’en font les acteurs professionnels et les jeunes eux-mêmes. Après avoir retracé les étapes de la constitution du phénomène de l’errance des jeunes en problème public, nous avons analysé le rôle de l’Etat social dans la prise en charge de ce problème, au prisme de la norme instituée de l’insertion pour les jeunes. Ceci nous a permis d’en pointer les apories et notamment la bascule rapide des jeunes cumulant des difficultés depuis l’enfance vers le circuit de l’infra-assistance. A l’aune de ces constats, nous montrons en quoi la relation d’aide devient un lieu de renégociation des objectifs de l’action publique, les artisans de la relation d’aide considérés étant les professionnels de terrain et les jeunes usagers des services d’aide. L’analyse des pratiques professionnelles nous a révélé leur caractère « bricolé ». Nous avons ici pu démontrer qu’elles permettaient de redéfinir les cadres de l’action publique en direction des « jeunes en errance ». Grâce à la mise en place d’une éthique de l’intervention centrée sur la prise en compte des spécificités des jeunes accueillis, les professionnels fabriquent des ponts leur permettant d’aller au-delà des manques de l’aide publique. Nous avons également analysé les comportements des jeunes fréquentant régulièrement les structures de l’urgence sociale. Leur mode de recours à l’aide leur permet d’asseoir une identité légitime de « jeunes en errance », qu’ils valorisent au sein de la relation d’aide. Ils mettent en place des stratégies identitaires les autorisant à renégocier les cadres de l’attribution de l’aide, en y ayant recours de manière détournée ou partielle. Ils ignorent ainsi les objectifs d’insertion qui lui sont attachés, en en faisant un usage routinier, les entretenant alors dans une carrière de « jeunes en errance ». / This research investigates the French public action category “jeunes en errance” (which will be translated by “homeless youth”). It aims at understanding the impact of this category on the implementation of the public action, through the analysis of the usage that both the professional actors and the youth make of it. After having redrawn the stages of the construction of the homeless youth phenomenon as a public problem, the analysis focused on the role of the Welfare state based on the instituted norm of the youth’s integration. Paradoxes of public action have thus been identified, such as the quick turnaround towards the infra-assistance system of young people who have accumulated difficulties since their childhood. In the light of these findings, the research then shows how this “support relationship” transforms itself in an arena for the renegotiation of the public action's objectives between the professionals on the one hand, and the youth recipients of the services on the other hand. The analysis of the professional's practices puts the light on their unstable dimension. The research has shown that these practices facilitated the redefinition of the frameworks of the public action toward “homeless youth”. Through the setting of an intervention’s ethics based on the specificities of each young person, the professionals manage to compensate the shortages of public assistance. The behavior of young people who frequently resort to the structures of social emergency have also been investigated. The analysis has identified the process of construction of a legitimate identity of “homeless youth”, which young people put forward within the assistance relationship. They set up identity strategies which enable them to renegotiate the conditions of the allocation of support, by resorting to it but only in a partial or in an indirect way. Thus, they ignore the insertion objectives which are attached to these public measures and make a routinized usage of them, which contributes to maintain them in a “homeless youth” career.

This study examined the translation of adjectival pre-modifiers (i.e. pre-modifying adjectives and pre-modifying participles) from English into Swedish. The selection of this topic and material was inspired by previous research on the increasing frequency of noun phrase pre-modification in English, contrasted with notions of Swedish-specific preferences for translating English pre-modifiers into different structures found in previous research and literature. Swedish tendencies included rendering English pre-modifiers as post-modification and the compounding of pre-modifying adjectives or participles with noun phrase heads to form Swedish compound nouns. The concept of translation shifts as labels for translation methods was used to classify translations of adjectival pre-modifiers, in addition to categorising the translation choices based on word class, rank and position. The study concluded that English adjectival pre-modifiers were overwhelmingly translated with formal correspondence (86%), i.e. as adjectival pre-modifiers. The other translation methods that were applied were used considerably less extensively; unit shifts and class shifts constituted 9% and 4% of all translation choices, respectively; omissions of the sense and meaning of the adjectival pre-modifier were found as the translation method for 1% of English adjectival pre-modifiers.  Unit shifts were found to result in a total of 8 different types of structural equivalents to adjectival pre-modifiers. In order of frequency, these were: prepositional phrase, first element of compound noun, extended attribute, pre-modifying prepositional phrase, verb phrase, first element of compound adverb, last element of compound participle and relative clause. Class shifts resulted in 3 categories of formally non-correspondent structures, namely adverb, noun and genitival attribute. The conclusions that could be drawn from the results were that the tendency for the Swedish translation of adjectival pre-modifiers to result in post-modification and compound nouns was small. A qualitative analysis showed that select examples of translations to formally correspondent equivalents were commonly motivated by considerations of readability to reduce sentence length and complexity. Examples of various category shifts were for the most part found to have been caused by the questionable idiomaticity of formally correspondent translation options.

Parte-se do pressuposto de que as diferenças existentes entre o PB e o PE se devem, não só a motivações internas à estrutura da língua, mas, principalmente, a motivações externas (sócio-históricas) decorrentes do contato entre línguas ocorrido, quando no Brasil conviveram os portugueses, os índios e os negros trazidos da África como escravos. Buscando avaliar o quanto o contato entre línguas afetou o desenvolvimento histórico da língua portuguesa no Brasil, o foco da pesquisa dirige-se para as comunidades rurais afrobrasileiras isoladas, do interior do Estado da Bahia. Por terem-se mantido até bem recentemente em relativo isolamento, tais comunidades devem guardar não só costumes culturais bastante antigos, mas também padrões lingüísticos, que permitam encontrar evidências de processos de variação e mudança resultantes do contato entre línguas. Dessa forma, o corpus analisado reuniu quatro comunidades localizadas em regiões diversas do Estado da Bahia, em que houve grande concentração de mão-de-obra escrava, a saber: Helvécia, no extremo-sul da Bahia; Rio de Contas, na Chapada Diamantina; Cinzento, no semi-árido; e Sapé, no Recôncavo Baiano. / Salvador

Title: Physical profile of judo athletes and its changes due to body weight reduction Aim of work: The aim of this study was to determine the effect of intensive pre-competitive body weight reduction on body composition, anthropometric parameters, postural stability, reaction time, maximal isometric muscle strength and biochemical parameters in the blood of elite judo athletes. Methods: The work compares the results of laboratory testing at the beginning and at the end of body weight reduction. Nine male judo athletes (age 22.3 ± 2.4 years) from the Czech national team participated in the research. For laboratory testing we used bioelectrical impedance analyser InBody 720, anthropometric equipment, pressure plate FootScan, dynamometer and apparatus for measuring reaction times of Biomedical laboratory UK FTVS and equipment for the collection of capillary and venous blood. We created a survey to gather more information about pre-competitive weight loss, attended by 53 competitors (37 men and 16 women, mean age 23.7 ± 3.2 years) who practise judo, wrestling Greco-Roman and freestyle, boxing, kickboxing, thaibox, taekwondo or karate. Results: We found a statistically significant (p<0.01) reduction of body weight, average weight loss was 4.6 % (on average 3.4 ± 1.6 kg). This reduction was reflected in...
