Previous issue date: 2014-08-14 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This work deals with the oblique pronouns o(s), a(s), me, te, starting from a syntactic
traditional analysis for a discursive approach based on the concepts of the functional linguistic
of the prototipicity, speech transitivity (Hopper and Thompson, 1980), discursive relevance
and textual-discursive function (Matos, 2008). The data analysed were extracted of the corpus
composed of three volumes of narratives narrated by Luiza Tereza, being this corpus part of
the acquis of the Paraibana popular culture present in the NUPPO (Núcleo de Pesquisa e
Documentação da Cultura Popular/Centre of Research and Documentation of the Popular
Culture). It has been found that the study of the grammatical categories is not valid if made in
an isolate way without observing, for example, speech transitivity that signal the syntactic
function involved. It is important to consider the prototypical function so that the analysis be
done on what is regular and in doing so the dimension of the results obtained is more
comprehensive, as the regular is more frequent, in other words, more recurring, facilitating the
more efficient comprehension as a function of the study. It was also confirmed the hypothesis
that the pronoun me listed for analysis is part of the narratives of high transitivity level, being
more to figure than to background. The prototypical function of the pronoun me is the
function of the object, being this direct or indirect and in both high discursive transitivity is
presented. / Este trabalho trata dos pronomes oblíquos o(s), a(s), me, te, partindo de uma análise sintática
tradicional para uma abordagem discursiva fundamentada nos conceitos de prototipicidade,
transitividade oracional (Hopper e Thompson, 1980), relevância discursiva e função textualdiscursiva
oriundos da Linguística funcional (Matos, 2008). Os dados analisados foram
do extraídos do corpus composto de três volumes de narrativas narrados por Luzia Tereza,
sendo este corpus parte do acervo da cultura popular paraibana presente no NUPPO (Núcleo
de Pesquisa e Documentação da Cultura Popular). Verificou-se que o estudo das categorias
gramáticas não é válido se feito isoladamente, sem observar, por exemplo, a transitividade
oracional que sinaliza a função sintática envolvida. É importante considerar a função
prototípica para que a análise seja feita em torno do que é regular e, assim, a dimensão dos
resultados obtidos é mais abrangente, visto que o regular é mais frequente, ou seja, mais
recorrente, facilitando a compreensão mais eficaz da função em estudo. Também foi
confirmada a hipótese de que o pronome me elencado para a análise está presente nas
narrativas em um nível de alta transitividade, estando mais para figura do que para fundo. A
função sintática prototípica desse pronome é a de objeto, sendo este direto ou indireto e, em
ambos os casos, apresenta alta transitividade discursiva.

實習諮商心理師的工作壓力、自我照顧重視知覺與自我照顧行為之關係 / The relationship among work-stress, perception of self-care emphasis, and self-care behavior in counseling trainees.洪育志, Hung, Yu Chih Unknown Date (has links)
本研究主要目的為探討實習諮商心理師的工作壓力、自我照顧重視知覺及自我照顧行為之間的關係。諮商心理師是個工作壓力特殊的行業,需要自我照顧來調節自己的工作壓力及維持專業服務的品質,而實習生是此工作的新手,對於其自我照顧狀態更需被關注。然而國外文獻中指出心理師有自我照顧不足的趨勢,在這樣的長期工作壓力及照顧不足的狀況下,容易令其陷入耗竭、同理疲乏等損傷的狀況。研究者認為若要增加諮商心理師的自我照顧能力或行為,在學習階段將自我照顧的概念或行為放入教育單位或實習單位的訓練中,讓實習諮商心理師知覺到其對自我照顧是重視的,應有助於諮商心理師執行自我照顧行為,此種知覺重視度的概念,稱為自我照顧重視知覺。然而國外的研究報告指出教育單位或實習單位並沒有積極提供自我照顧的相關課程或訓練,國內亦沒有探討實習諮商心理師知覺教育訓練單位對於自我照顧重視度的研究,且有關實習生的自我照顧研究亦不多,因此本研究欲探討此主題。研究者以問卷調查方式收集國內143位全職實習諮商心理師的資料,進一步以差異分析、相關分析及階層迴歸分析等統計方法來了解其現況及工作壓力、自我照顧重視知覺及自我照顧行為三者間的變項關係。
本研究結果指出:1.實習諮商心理師在實習期間有低程度的工作壓力,其中較高的是「專業角色壓力」以及「與督導有關的壓力」,而自我照顧重視知覺及自我照顧行為也皆為中等程度。2.實習於大專院校的實習諮商心理師,工作壓力顯著高於在高中/職及醫療院所實習的實習諮商心理師;另外大學畢業於心理相關科系及非相關科系的實習諮商心理師,其工作壓力顯著高於大學畢業於心理諮商本科系的實習諮商心理師。3.實習諮商心理師的工作壓力與自我照顧重視知覺之間達顯著低度負相關,工作壓力與自我照顧行為達顯著低度負相關,自我照顧重視知覺與自我照顧行為達顯著中度正相關。4.工作壓力在自我照顧重視知覺與自我照顧行為關係中具調節效果。研究者根據上述研究結果進行討論並對實務及未來研究提出建議。 / This study examined the relation between work-stress, perceptions of self-care emphasis, and self-care behavior among a convenience sample of 143 counseling psychology graduate students. Specifically, this study proposed that there would be a relation between graduate trainee’s perceptions of self-care emphasis and graduate trainee’s self-care behavior and that this relation would be modified by work-stress of the graduate trainee. A non-experimental designed examined the linear relations among the 3 variables, which were assessed by two measures modified by the authors (work-stress scale of陳俊任 (2012) and perceptions of self-care emphasis questionnaire of Goncher, Sherman, Barnett, & Haskins (2013)) and the self-care behavior scale of張吟慈 (2008).
Results of this study showed that (1) graduate trainees had low level work-stress , moderate level perception of self-care emphasis , and moderate level self-care behaviors during internship , (2) The work-stress of graduate trainee intern in colleges is greater than in high school and in the hospital, and the work-stress of graduate trainees graduated from the department of non-psychology is greater than from the department of psychology , (3) there was a low level significant negative relation between work-stress and perceptions of self-care emphasis positive, a low level significant negative relation between work-stress and self-care behaviors, and a moderate level significant positive relation between perceptions of self-care emphasis and self-care behaviors, (4) The test for modification as outlined by Baron and Kenny (1986) demonstrated support by the survey data as perceptions of self-care emphasis was a positive predictor of self-care behaviors and that this relation was modified by work-stress. Implications for training programs are addressed, and recommendations for individual and systemic changes to promote a culture of self-care within graduate training in professional psychology are provided that should be helpful for promoting enhanced self-care behavior among psychology graduate students.

[en] SCIENTIFIC LITERACY IN BRASIL AND JAPAN THROUGH PISA S RESULTS / [pt] LETRAMENTO CIENTÍFICO NO BRASIL E NO JAPÃO A PARTIR DOS RESULTADOS DO PISAANDRIELE FERREIRA MURI 26 July 2017 (has links)
[pt] Este estudo compara o Letramento Científico dos estudantes brasileiros e japoneses, com base nos resultados do PISA e procura responder às seguintes as questões de pesquisa: a) Há diferenças de competência cognitiva em Ciências entre os alunos brasileiros e dos outros países, sobretudo os do Japão no PISA?; b) Existem itens do PISA 2006 que apresentam comportamento diferencial, tendo o Brasil como referência?; e c) É possível, a partir dos dados do PISA e da adoção complementar de uma abordagem qualitativa, identificar diferentes ênfases curriculares e/ou práticas pedagógicas no Ensino de Ciências de Brasil e Japão que contribuam para a compreensão das diferenças de desempenho entre seus estudantes? Para responder a primeira questão, comparamos os resultados do Brasil e do Japão nas edições 2006 e 2015 do PISA, em que o foco foi Ciências. O Brasil se mostra em situação de desvantagem em relação a quase todos os países que participaram do Programa, o que é em parte explicado pela repetência. Na
escala de desempenho, o Brasil permanece no nível 1 e o Japão, no nível 3 em2006, passou para o nível 4 em 2015. Para responder à segunda questão, utilizamos a análise de Differential Item Functioning (DIF) nos itens da prova de Ciências de 2006 e concluímos que há grande presença de DIF nesses itens
comparativamente entre o Brasil e o Japão. Apesar de não serem capazes de comprometer o processo avaliativo privilegiando um grupo em detrimento do outro, esses itens sugerem diferentes ênfases curriculares em Ciências. Levando em conta essa hipótese e para responder à terceira questão adotamos uma abordagem qualitativa, com observação do uso do tempo das aulas; registro das ênfases curriculares e da ocorrência de atividades relacionadas à interação, investigação, experimentação e aplicação na perspectiva dos alunos, professores e da observação; e entrevistas com especialistas e gestores. Os
resultados mostraram que mais de 20 por cento do tempo oficial de aula observados no Brasil são desperdiçados com questões outras que não o ensino efetivo de Ciências; 10 vezes mais que no Japão. No Brasil, há ênfase curricular mais acentuada nas Ciências Naturais e Biológicas. O currículo é distribuído mais homogeneamente no Japão e é seccionado no Brasil. Segundo os estudantes japoneses, não são freqüentes as atividades de interação, investigação, experimentação e aplicação. As atividades mais recorrentes observadas e percebidas pelos professores japoneses são as de experimentação e interação; no Brasil, as de interação e aplicação. Entrevistas realizadas com especialistas em Ensino de Ciências e gestoras do PISA, no Brasil e no Japão, mostraram que o sucesso do Japão nessa avaliação é associado à existência de um currículo nacional comum e à formação continuada de professores em serviço, bem como às reformas do sistema educacional japonês suscitadas pelos resultados do PISA. O baixo desempenho dos estudantes brasileiros no PISA estaria, por sua vez, relacionado com o despreparo dos estudantes, com a falta de familiaridade destes com o teste, com a deficiente formação dos professores e com o limitado uso das evidências produzidas pelas avaliações em larga escala. / [en] This study compares the Scientific Literacy of Brazilian and Japanese students, based on the results of PISA and seeks to answer the following research questions: a) Are there differences of cognitive competence in Science among Brazilian students and those from other countries, especially Japan, in the PISA ?; B) Are there items of PISA 2006 that present differential functioning, with Brazil as a reference ?; and c) Is it possible, based on the PISA data and the complementary adoption of a qualitative approach, to identify different curricular emphases and / or pedagogical practices in Science Education in Brazil and Japan
that contribute to the understanding of differences in performance among their students? To answer the first question, we compared the results of Brazil and Japan in the 2006 and 2015 editions of PISA, where the focus was Science. Brazil is disadvantaged compared to almost all the countries that participated in the
Program, which is partly explained by the repetition. In the performance scale, Brazil remains at level 1 and Japan at level 3 in 2006 has moved to level 4 in 2015. In order to answer the second question, we used the Differential Item Functioning (DIF) analysis in the 2006 test s Science items and we conclude that
there is a large presence of DIF in these items comparatively between Brazil and Japan. Although they are not able to compromise the evaluation process by favoring one group over the other, these items suggest different curricular emphases in Science. Taking into account this hypothesis and to answer the third
question we adopted a qualitative approach, with observation of the use of class time; record of curricular emphases and the occurrence of activities related to interaction, investigation, experimentation and application from the perspective of students, teachers and observation; and interviews with experts and
PISA managers. The results showed that more than 20 percent of official classroom time observed in Brazil is wasted with questions other than effective teaching of science; 10 times more than in Japan. In Brazil, there is a more pronounced curricular emphasis in Natural and Biological Sciences. The curriculum is distributed more homogeneously in Japan and is sectioned in Brazil. According to Japanese students, activities of interaction, investigation, experimentation and application are not frequent. The most recurrent activities observed and perceived by Japanese teachers are those of experimentation and interaction; In Brazil, those of interaction and application. Interviews with experts in Science Education and PISA managers in Brazil and Japan have shown that Japan s success in this assessment is associated with the existence of a common national curriculum and the teachers ongoing in-service training as well as the educational system reforms raised by the PISA results. The low performance of Brazilian students in PISA
would, in turn, be related to the lack of preparation of the students, their lack of familiarity with the test, poor teacher training and the limited use of the evidence produced by the large scale evaluations.

Transforming high-effort voices into breathy voices using adaptive pre-emphasis linear predictionNordstrom, Karl 29 April 2008 (has links)
During musical performance and recording, there are a variety of techniques and electronic effects available to transform the singing voice. The particular effect examined in this dissertation is breathiness, where artificial noise is added to a voice to simulate aspiration noise. The typical problem with this effect is that artificial noise does not effectively blend into voices that exhibit high vocal effort. The existing breathy effect does not reduce the perceived effort; breathy voices exhibit low effort.
A typical approach to synthesizing breathiness is to separate the voice into a filter representing the vocal tract and a source representing the excitation of the vocal folds. Artificial noise is added to the source to simulate aspiration noise. The modified source is then fed through the vocal tract filter to synthesize a new voice. The resulting voice sounds like the original voice plus noise.
Listening experiments were carried out. These listening experiments demonstrated that constant pre-emphasis linear prediction (LP) results in an estimated vocal tract filter that retains the perception of vocal effort. It was hypothesized that reducing the perception of vocal effort in the estimated vocal tract filter may improve the breathy effect.
This dissertation presents adaptive pre-emphasis LP (APLP) as a technique to more appropriately model the spectral envelope of the voice. The APLP algorithm results in a more consistent vocal tract filter and an estimated voice source that varies more appropriately with changes in vocal effort. This dissertation describes how APLP estimates a spectral emphasis filter that can transform the spectral envelope of the voice, thereby reducing the perception of vocal effort.
A listening experiment was carried out to determine whether APLP is able to transform high effort voices into breathy voices more effectively than constant pre-emphasis LP. The experiment demonstrates that APLP is able to reduce the perceived effort in the voice. In addition, the voices transformed using APLP sound less artificial than the same voices transformed using constant pre-emphasis LP. This indicates that APLP is able to more effectively transform high-effort voices into breathy voices.
