New advances in aircraft MRO services: data mining enhancement

Aircraft Maintenance, Repair and Overhaul (MRO) agencies rely largely on row-data based quotation systems to select the best suppliers for the customers (airlines). The data quantity and quality becomes a key issue to determining the success of an MRO job, since we need to ensure we achieve cost and quality benchmarks. This paper introduces a data mining approach to create an MRO quotation system that enhances the data quantity and data quality, and enables significantly more precise MRO job quotations. Regular Expression was utilized to analyse descriptive textual feedback (i.e. engineer’s reports) in order to extract more referable highly normalised data for job quotation. A text mining based key influencer analysis function enables the user to proactively select sub-parts, defects and possible solutions to make queries more accurate. Implementation results show that system data would improve cost quotation in 40% of MRO jobs, would reduce service cost without causing a drop in service quality.

Improving aircraft maintenance, repair, and overhaul: A novel text mining approach

Aircraft Maintenance, Repair and Overhaul (MRO) feedback commonly includes an engineer’s complex text-based inspection report. Capturing and normalizing the content of these textual descriptions is vital to cost and quality benchmarking, and provides information to facilitate continuous improvement of MRO process and analytics. As data analysis and mining tools requires highly normalized data, raw textual data is inadequate. This paper offers a textual-mining solution to efficiently analyse bulk textual feedback data. Despite replacement of the same parts and/or sub-parts, the actual service cost for the same repair is often distinctly different from similar previously jobs. Regular expression algorithms were incorporated with an aircraft MRO glossary dictionary in order to help provide additional information concerning the reason for cost variation. Professional terms and conventions were included within the dictionary to avoid ambiguity and improve the outcome of the result. Testing results show that most descriptive inspection reports can be appropriately interpreted, allowing extraction of highly normalized data. This additional normalized data strongly supports data analysis and data mining, whilst also increasing the accuracy of future quotation costing. This solution has been effectively used by a large aircraft MRO agency with positive results.

Voice, appropriation and discourse representation in a student writing task

We investigate the practices by which bilingual university students in Hong Kong appropriate texts in producing utterances, particularly written texts. Following Wertsch and his colleagues we ask: • To what extent do our students appropriate texts in constructing their own discourses? • What linguistic means do they use to do this? • What can these processes tell us about what they now can do with discourse representation; and • What do we need to teach them? This research shows that our students' writing displays considerable intertextuality and interdiscursivity. Responses to this writing in tutorial sessions indicate that they are skilled at orchestrating the multiple voices within their own discourses. The commonly stated concern that our students do not know how to do quotation and citation correctly is somewhat misplaced and researchers need to move the focus away from the mechanisms of citation and attribution to the social practices of textual appropriation.

Representation and interpretation : textbooks, teachers, and historical culture

This article presents a study of how contemporary Swedish lower secondary school textbooks present the emergence of the Cold War and how 10 active lower secondary school history teachers interpreted a quotation that was ambiguous in relation to the general narrative in the studied Swedish textbooks, seeking to analyse textbooks both from the perspectives of content and reception. Applying a theoretical framework of uses of history, the study finds that the narratives presented in the studied textbooks are what could be called traditional in the sense that they do not acknowledge perspective and representation in history. While the interviewed teachers generally acknowledged that textbook narratives are representations of history and contingent on perspective, few teachers extended this to include how their own views affect their interpretations, suggesting an intermediary appreciation of the contextual contingency of historical narratives.

A divulgação do conhecimento científico sob uma perspectiva enunciativa

Esta dissertação focaliza um gênero textual denominado texto de divulgação científica, o qual tem por objetivo divulgar as recentes descobertas científicas. Ao se tratar de um modelo textual com peculiaridades próprias, busca-se, a partir do conceito bakhtiniano de gênero, classificá-Io corno um gênero emergente, por estar cadavez mais freqüente na rnídia impressa e eletrônica. Assim, o objetivo desse trabalho é mostrar como esse gênero textual é configurado por meio de estratégias lingüísticas que caracterizam o dialogismo e a polifonia. Para atingir tal propósito procedeu-se a uma análise enunciativa de textos de divulgação científica veiculados na Folha online, procurando verificar os diferentes recursos lingüísticos empregados para reformulação do referido texto a partir do texto original -o artigo científico. Os resultados apontam o texto de divulgação científica como um gênero predominantemente politõnico, pois, ao jogar com recursos disponíveis na língua, como por exemplo aspas, parênteses e certos marcadores discursivos, o divulgador tem a possibilidade de transformar um texto que apresenta maior grau de objetividade, imparcialidade e emprego de palavras técnicas, características próprias do artigo de cunho científico, em um texto constituído por uma - linguagem com palavras próximas do cotidiano do leitor e, portanto, permitindo uma leitura mais acessível.

Precificação de ativos sem cotação corrente de mercado na indústria de private equity e venture capital no Brasil

Neste trabalho são estudadas as características do mercado de private equity e venture capital no Brasil, particularmente no que se refere às metodologias de avaliação de investimentos, com o intuito de procurar identificar o método que se ajusta melhor à realidade brasileira para mensuração de ativos sem cotação corrente de mercado, presentes nas carteiras dos Fundos Mútuos de Investimento em Empresas Emergentes e Fundos de Investimento em Participações. Para atingir este objetivo, serão discutidos os principais mercados no exterior, ou seja, Estados Unidos e Europa, bem como as características específicas deste mercado no Brasil, além de apresentar como a Comissão de Valores Mobiliários trata o assunto, uma vez que os ativos aqui tratados não possuem marcação a mercado, como ocorre em outros fundos disciplinados por esta autarquia. Em seguida, são descritas as metodologias a partir das quais serão investigadas as formas como as organizações gestoras abordam os métodos em seus regulamentos e confrontadas as opiniões das organizações mencionadas com as dos investidores. Por fim, busca-se atingir o objetivo proposto utilizando o comportamento do valor das cotas no período de vida dos fundos como indicador do método mais apropriado.

Eficiência e razão de hedge: uma análise dos mercados futuro brasileiros de boi, café, etanol, milho e soja

This research aims to investigate the Hedge Efficiency and Optimal Hedge Ratio for the future market of cattle, coffee, ethanol, corn and soybean. This paper uses the Optimal Hedge Ratio and Hedge Effectiveness through multivariate GARCH models with error correction, attempting to the possible phenomenon of Optimal Hedge Ratio differential during the crop and intercrop period. The Optimal Hedge Ratio must be bigger in the intercrop period due to the uncertainty related to a possible supply shock (LAZZARINI, 2010). Among the future contracts studied in this research, the coffee, ethanol and soybean contracts were not object of this phenomenon investigation, yet. Furthermore, the corn and ethanol contracts were not object of researches which deal with Dynamic Hedging Strategy. This paper distinguishes itself for including the GARCH model with error correction, which it was never considered when the possible Optimal Hedge Ratio differential during the crop and intercrop period were investigated. The commodities quotation were used as future price in the market future of BM&FBOVESPA and as spot market, the CEPEA index, in the period from May 2010 to June 2013 to cattle, coffee, ethanol and corn, and to August 2012 to soybean, with daily frequency. Similar results were achieved for all the commodities. There is a long term relationship among the spot market and future market, bicausality and the spot market and future market of cattle, coffee, ethanol and corn, and unicausality of the future price of soybean on spot price. The Optimal Hedge Ratio was estimated from three different strategies: linear regression by MQO, BEKK-GARCH diagonal model, and BEKK-GARCH diagonal with intercrop dummy. The MQO regression model, pointed out the Hedge inefficiency, taking into consideration that the Optimal Hedge presented was too low. The second model represents the strategy of dynamic hedge, which collected time variations in the Optimal Hedge. The last Hedge strategy did not detect Optimal Hedge Ratio differential between the crop and intercrop period, therefore, unlikely what they expected, the investor do not need increase his/her investment in the future market during the intercrop

Mens sana in corpore sano: compreensões de corpo, saúde e educação

This thesis proposes that the idea expressed in Juvenal s quotation Mens Sana in Corpore Sano, produced in the Ancient Greek-Roman civilization includes undestandings of body, heath and education that were reapropriated and reorganized by scientific and pedagogical theories in the XIX and XX centuries. These theories, especially the ones that received contributions from the biomedical sciences, have influenced Physical Education in the search of becoming a science. In order to realize this reapropriation, we have analyzed the transformations in the concepts of body, health and education produced in the area discourse, aiming at pointing out elements to the configuration of a theory that is being called Corpore Sano. The theory constitutes in possible systematization of scientific, philosophical and pedagogical concepts, and as such, an understanding of the scientific fundaments of Physical Education. The corpus of this analysis was composed by 148 articles that were published in Revista Brasileira de Ciências do Esporte digitalized in the period between 1979 and 2003 and selected according to theme: body, biology, physical activity, effort physiology and health. The analysis of the content and the referential interpretation allowed the combination of philosophical reflection with attention to the empiric field as a comprehensive dimension. Based on the corpus of the analysis it is possible to configure meta-arguments about the concepts of body, health and education in the scientific production of Physical Education. As a metaresearch. Our study did not intend to judge the analyzed production, but look for theoretical elements that may generate a reflection about the scientific rationality in Physical Education and developments in the pedagogical field and in body practices. Such a reflection might be recognized as a theory of the living body, susceptible to modifications and interrogations that are proper of knowledge and practices of Physical Education. It is a theory rejects the idea of the complete truth and holds the comprehension that the truth is built historically through relations among different kinds of knowledge and Physical Education practices

O discurso de outrem em retextualizações

This work investigates features that speakers use to introduce different voices during retextualization of a literary work. It presents events revealing different resources used, characterizing the discursive heterogeneity, recognized through various brands such as quotation marks, italics, etc. The material analyzed, ie, the corpus of this research, consists of 65 essays from the reading of a literary work - Jealous of Card, Moacyr Scliar - produced by students of the 8th year of high school while in the classroom. The data revealed that the resource most used by students was the indirect discourse, although there also occurred the use of other resources such as free indirect discourse and modalizations in fewer redactions. Notably, the autonym connotation was noted through the use of quotation marks, and the use of parentheses. The recurrence of the parentheses seem to be justified by the need to make clearer sentences that could raise questions to the reader, since the protocol request retextualization established a thirty lines of text, which would certainly limit the possibilities of expansion of the text

A educação em saúde pública na práqtica cotidiana: atuação dos cirurgiões-dentistas do PSF de Natal-RN

Considering education a support to health promotion, care integration and citizenship formation,the purpose of this research was to analyze the perception of the oral surgeons from the Family Health Program of Natal-RN over education in health as well as their performance as educators based on their activities on the program. A qualitative study was accomplished by a semi-structured interview and a Free Association of Words Test with 80 oral surgeons from the Family Health Program of Natal-RN. The instruments were analyzed through the meaning analysis and the Central Nucleus of Vergès Theory. The results showed a lack of planning in health actions so there is no standardization on the educative practices done by the oral surgeons which mostly are focused on scholars. There was an agreement among the group according to the oral surgeons´ perception about education in health that education is related to its function of recall prevention ideas to the population. Most part of the context units analyzed by the professionals´ speech show the knowledge of education in health as an inadequate behavior change instrument of the individuals. An interesting point was a quotation cited by some professionals that included actual themes such as citizenship, motivation and life quality, put inside the speech of education in health. To the oral surgeons the biggest difficulties on the development of the educative actions are due to the lack of incentive by the Municipal Health Bureau and to the detachment and lack of valorization of the themes by the population. The oral surgeons consider themselves co-responsible for the formation of a population which is able to request its health. They also mention the knowledge about the need of the community participation on the planning of the Family Health Program actions. Finally, it is notable the need for more encouragement so the oral surgeons can be more capable and have more interest in applying education in health on the perspective of a new model in health, because once capable and stimulated they can awake the population to education importance as a great transformation instrument for people searching for a fair, equalitarian and citizeness society

A presença da literatura/cultura portuguesas em periódicos paulistas - 1900-1922

Partindo-se do pressuposto de que existe uma interligação, por meio da presença da literatura/cultura portuguesa, entre Portugal e a cidade de São Paulo – no período de 1900-1922, caracterizado ainda como pré-modernista brasileiro –, a proposta deste texto dirige-se ao comentário de alguns periódicos (O Estado de S. Paulo; A Vida Moderna; O Pirralho), visto que “[...] há uma história da literatura que se projeta na cidade de S. Paulo; e há uma história da cidade de S. Paulo que se projeta na literatura.” (CANDIDO, 1975). Assim, pretende-se verificar como a presença da literatura/cultura portuguesa (principalmente autores canônicos do século XIX) repercutiu na vida social e intelectual da cidade de São Paulo, para melhor compreensão das formas de sociabilidade, bem como a caracterização das diferentes etapas percorridas pela literatura brasileira em São Paulo.
