Gender-Related Terms in English Depositions, Examinations and Journals, 1670–1720

Lilja, Sara January 2007 (has links)
<p>This dissertation focuses on gender-related terms as well as adjectives and demonstratives in connection with these terms used in texts from the period 1670–1720. The material in the study has been drawn from both English and American sources and comes from three text categories: depositions, examinations and journals. Two of these text categories represent authentic and speech-related language use (depositions and examinations), whereas the third (journals) is representative of a non-speech-related, non-fictional text category. While previous studies of gender-related terms have primarily investigated fictional material, this study focuses on text categories which have received little attention so far. </p><p>The overarching research question addressed in this study concerns the use and distribution of gender-related terms, especially with regard to referent gender. Data analyses are both quantitative and qualitative, and several linguistic and extra-linguistic factors are taken into account, such as the semantic domain to which the individual gender-related term belongs, region of origin and referent gender. Adjectives and demonstratives collocating with the gender-related terms are also investigated, as previous research has shown that referent gender has an impact on the use of adjectives as well.</p><p>The results show that the use of gender-related terms is influenced by both region of origin and referent gender. It is suggested that this is due in part to the difference in nature between Early Modern English society and the early American colonies, and in part due to the social roles which men and women had. Referent gender also has an impact on the type of adjectives used in connection with gender-related terms: adjectives collocating with gender-related terms denoting men have positive connotations to a larger extent than do adjectives collocating with their female counterparts; meanwhile, gender-related terms denoting women tend to collocate with negative adjectives. </p>

Investigations of calorimeter clustering in ATLAS using machine learning

Niedermayer, Graeme 11 January 2018 (has links)
The Large Hadron Collider (LHC) at CERN is designed to search for new physics by colliding protons with a center-of-mass energy of 13 TeV. The ATLAS detector is a multipurpose particle detector built to record these proton-proton collisions. In order to improve sensitivity to new physics at the LHC, luminosity increases are planned for 2018 and beyond. With this greater luminosity comes an increase in the number of simultaneous proton-proton collisions per bunch crossing (pile-up). This extra pile-up has adverse effects on algorithms for clustering the ATLAS detector's calorimeter cells. These adverse effects stem from overlapping energy deposits originating from distinct particles and could lead to difficulties in accurately reconstructing events. Machine learning algorithms provide a new tool that has potential to improve clustering performance. Recent developments in computer science have given rise to new set of machine learning algorithms that, in many circumstances, out-perform more conventional algorithms. One of these algorithms, convolutional neural networks, has been shown to have impressive performance when identifying objects in 2d or 3d arrays. This thesis will develop a convolutional neural network model for calorimeter cell clustering and compare it to the standard ATLAS clustering algorithm. / Graduate

[en] UNIVERSITY PROFESSORS: THEIR VALUES AND THE OPTION FOR THE ENVIRONMENTAL EDUCATION / [pt] PROFESSORES UNIVERSITÁRIOS: SEUS VALORES E A OPÇÃO DA EDUCAÇÃO AMBIENTAL

LUCIANA MELLO RIBEIRO 08 January 2018 (has links)
[pt] A Educação Ambiental (EA), um novo paradigma educacional, vem enfrentando uma série de desafios em seu processo de institucionalização no Brasil e no mundo, nestes seus pouco mais de 30 anos de trajetória. Desde 1999, a Lei Nacional de EA garante a obrigatoriedade de sua difusão em todas as instâncias sociais, seja nos meios de comunicação, nas empresas, no campo, ou em cada nível do ensino formal. Sua natureza interdisciplinar fez com que se propusesse incorporá-la de modo transversal nos processos educativos. Considerando as dificuldades de ordem cultural, burocrática, política, e mesmo psicológicas e sociais, tal proposição, com todos os avanços que se fez, segue ainda distante do horizonte desejado. A universidade, idealmente, deveria ser um dos locus transformadores da realidade, já que se propõe ser um espaço para formação educacional em diversos sentidos. Entretanto, sendo tradicionalmente conservadora em termos de práticas, não manifesta situação melhor quanto à EA. Ainda assim, existem docentes universitários que arrostam as dificuldades e desenvolvem práticas educativo-ambientais de fato engajadas e transformadoras. O que os motiva e mobiliza nesse sentido é a questão que orientou esta pesquisa. Tomou-se por hipótese serem os valores pessoais o fator decisivo nesta opção. Neste caso, que meios e experiências morais teriam produzido tais valores? De que forma? Como se expressam? Em busca de entender esta motivação lançou-se mão da história oral, através de sua modalidade conhecida por depoimentos pessoais, colhidos estes por meio de entrevistas. Mesclando memórias, práticas cotidianas e escolhas, a entrevista percorreu a trajetória pessoal e profissional destes docentes, procurando ir além da mera teorização em torno de valores desejados. Assim, foram confrontadas a prática e os ideais de cada docente, sendo tomados por indicadores de alinhamento entre discurso e valores a coerência e a vergonha. A riqueza dos relatos indica forte relação entre os valores principais de cada professor e sua prática social. Em comum, tais professores têm um perfil idealista e gosto pela vida, valorizando a justiça, a solidariedade, a gratidão, a relação humana e a responsabilidade, elementos aos quais conseguem dar corpo através de grande engajamento e dedicação ao trabalho, entendido e buscado enquanto meio de realização de seu projeto de vida. Idéias inatas, experiências familiares, sócio-culturais e educativas parecem ter contribuído para as escolhas existenciais dos docentes estudados. Espera-se que a identificação destes perfis e experiências formadoras possa inspirar a criação de processos educativos, iniciais ou continuados - tendo em vista a generalização do saber ambiental e do sujeito ecológico. Pretende-se, por fim, que a presente tese venha a contribuir para o debate acerca do processo pedagógico formador de valores no âmbito da Educação Ambiental. / [en] Environmental Education (EE), a new educational paradigm, has been facing several challenges during its institutionalization process in Brazil and in the world over its thirty years trajectory. Since 1999, the Brazilian EE National Law made mandatory its diffusion in every social instance, such as the media, enterprises, countryside municipalities, and within each formal education level. The EE interdisciplinary nature has indicated its inclusion through a transversal approach within educational processes. Considering the difficulties within cultural, bureaucratic, politic and even psychological and social instances, such proposition continues - besides many developments achieved -, far from its goal. The institution of higher education, ideally, should be a social changing locus, as it has the purpose of being a place for educational development in many ways. However, being traditionally conservative within its practices, it is not doing well concerning EE. Even so, there are professors whom, despite difficulties, develop educative-environmental practices truly committed with social change. The reasons which motivate and mobilize them in this direction are the key matter that guided this research. By hypothesis, this work proposes that personal values are decisive factors leading these university teachers into this option. In this case, what means and moral experiences have produced such values? How was it? How are they regularly expressed? In order to understand their motivation it was applied the oral history research approach through personal depositions, obtained through interviews. Mixing memories, daily practices, and choices, the interviews explore university teacher s personal and professional trajectory, trying to proceed beyond simple theorizations about required values. Furthermore, their practice and educational ideals were compared, being taken the coherence and the shame as alignment indicators between their speeches and values. A large quantity of stories indicates a strong relation between the main values of each teacher and their social practice. Yet, as a common characteristic, such professors share an idealistic profile and taste for life, valuing justice, solidarity, gratitude, human relationship and responsibility, elements which they develop by great commitment and dedication to work, understood and pursued as life project accomplishments. Innate ideas, family background, educational and social-cultural experiences also seem to have contributed to the life choices of our research s participants. It is expected the investigation of these personal profiles and experiences may inspire the development of learning processes, within initial or further education levels, in order to disseminate the Environmental Knowledge and the Ecological Subject matter. It is intended, ultimately, this thesis can contribute to the discussion about value-maker pedagogical processes within the Environmental Education field.
