Definição do conceito de blended learning. Proposta metodológica no quadro da terminologia de base conceptual

Sustentado numa abordagem conceptual da Terminologia, o trabalho de investigação que a seguir se desenvolve visa propor um cenário de resposta à questão: como se define o blended learning no contexto educativo de Ensino Superior Pós-Bolonha? A necessidade de compreender, delimitar e harmonizar o conceito de blended learning no panorama actual do Ensino Superior, resulta do pressuposto de que muito embora proliferem descrições de práticas e modelos para a sua operacionalização de reconhecida qualidade - tal como sucede com outros conceitos sob alçada da educação a distância - a reflexão teórica é ainda insuficiente. Com efeito, para responder à questão supra-colocada, propõe-se o desenho de uma metodologia para construção de uma definição intensional do conceito de blended learning que herde, subsuma e melhore o conhecimento existente, identificado através da análise de texto para fins onomasiológicos e de um processo de elicitação de conhecimento tácito e de negociação discursiva junto de sujeitos especializados. A proposta de desenho metodológico que neste trabalho de esboça escora-se globalmente em três etapas: (1) etapa exploratória do domínio-objecto de estudo; (2) etapa de análise onamasiológica de evidência textual e discursiva; (3) etapa de modelização e de validação de resultados. Pretende-se, em primeiro lugar, através do estudo do espaço conceptual das modalidades de educação que se situam no continuum presença-distância sistematizar e ordenar as visões analisadas, propondo representações de educação presencial, educação a distância, e-learning, educação online, aprendizagem enriquecida por tecnologias e ainda de outras modalidades emergentes. As representações assumem o carácter de proposta aberta e decorrem da necessidade de uma primeira ordenação no sentido de topografrar, delineando - a um nível macro - o possível lugar do conceito de blended learning naquele cenário. Num segundo momento, aprofunda-se e circunscreve-se a análise, depurando a evidência observada, agora reduzida a um conjunto de contextos ricos em informação conceptual – um corpus escrito e oral de definições e descrições de blended learning – identificando candidatas a características essenciais e candidatas a características acidentais. Num terceiro momento, procede-se à modelização do conhecimento, encapsulando-a numa proposta de definição sujeita a um processo iterativo e reflexivo, constituído por um conjunto de ciclos de investigação-acção, os quais reflectem a sequência de interacções entre o terminólogo e sujeitos especializados. Defender-se-á que a experimentação deste desenho revela a produtividade de uma sequência cíclica entre a análise textual e discursiva para fins onomasiológicos, a interacção colaborativa e a introspecção. Por outras palavras, embora a natureza do estudo realizado não permita a generalização, para além da relação diádica de mediação que o terminológo estabelece com o especialista, defende-se a produtividade de um procedimento de acção-reflexão autónomo, solitário e introspectivo, no âmbito da qual o terminólogo se afirma como sujeito conceptualizador, decisor e interventor. Resultam deste percurso uma proposta de definição e de descrição de blended learning em língua portuguesa que acreditamos poder servir diferentes actores da comunidade académica envolvida neste domínio de especialidade.

Estrutura Conceptual do Relato Financeiro : Da Definição de um Domínio à Sua Análise para uma Sociedade em Rede

Considerando a língua como um produto da sociedade, mas também como um meio fundamental para o estabelecimento de relações entre os homens, procuramos perceber o seu lugar na sociedade globalizada, com o objectivo de desenvolver uma metodologia de análise terminológica que contribua para uma maior qualidade da comunicação especializada na sociedade em rede. Este trabalho está organizado em duas partes, sendo a primeira dedicada à reflexão sobre o papel da língua na sociedade em rede, focando questões essenciais em torno da tensão existente entre o multilinguismo e a hegemonia do inglês enquanto lingua franca, sobretudo no espaço europeu. Interessa-nos, por um lado, reflectir sobre a definição de políticas linguísticas, concretamente na Europa multilingue dos 28, e, por outro, salientar o papel preponderante que a língua tem na transmissão do conhecimento. A segunda parte deste trabalho concretiza a investigação efectuada na primeira com base na análise do relato financeiro, um domínio do saber que não só é inerentemente multilingue ¾ porque a sua aplicação é transnacional ¾ mas também reflecte a tensão identificada na primeira parte, na medida em que o inglês assume, no mundo dos negócios em geral e nos mercados financeiros em particular, o papel hegemónico de lingua franca. A abordagem terminológica que defendemos é semasiológica para fins onomasiológicos, pelo que partimos da análise do texto de especialidade, organizado em corpora de especialidade. Discutimos subsequentemente os resultados da nossa análise com os especialistas que os irão validar e cuja colaboração em diversos vi momentos do processo de análise terminológica e conceptual é fundamental para garantir a qualidade dos recursos terminológicos produzidos. Nesta óptica, exploramos um corpus de textos legislativos no âmbito do Sistema de Normalização Contabilística (SNC), de modo a delinearmos uma metodologia de trabalho que, no futuro, conduzirá à construção de uma base de dados terminológica do relato financeiro. Concomitantemente, efectuamos também um estudo sobre a Estrutura Conceptual do SNC, para o qual elaboramos uma comparação ao nível da tradução especializada no relato financeiro, com base num corpus paralelo composto pela legislação contabilística internacional endossada pela União Europeia. Utilizamos o corpus paralelo constituído por textos redigidos originalmente em inglês e traduzidos para português, em articulação com o corpus de especialidade criado com a legislação relativa ao normativo contabilístico português, para testar uma metodologia de extracção de equivalentes. Defendemos, por fim, que a harmonização no relato financeiro para além de se reger por políticas contabilísticas comuns, deve ter subjacentes questões terminológicas. É necessário, portanto, harmonizar a terminologia do relato financeiro, possibilitando aos especialistas uma comunicação em português isenta da interferência do inglês herdado das normas internacionais, através dos dois processos que identificamos: a tradução e a adaptação das Normas Internacionais de Contabilidade.

Characterizing the vulnerability of frequent emergency department users by applying a conceptual framework: a controlled, cross-sectional study.

BACKGROUND: Frequent emergency department (ED) users meet several of the criteria of vulnerability, but this needs to be further examined taking into consideration all vulnerability's different dimensions. This study aimed to characterize frequent ED users and to define risk factors of frequent ED use within a universal health care coverage system, applying a conceptual framework of vulnerability. METHODS: A controlled, cross-sectional study comparing frequent ED users to a control group of non-frequent users was conducted at the Lausanne University Hospital, Switzerland. Frequent users were defined as patients with five or more visits to the ED in the previous 12 months. The two groups were compared using validated scales for each one of the five dimensions of an innovative conceptual framework: socio-demographic characteristics; somatic, mental, and risk-behavior indicators; and use of health care services. Independent t-tests, Wilcoxon rank-sum tests, Pearson's Chi-squared test and Fisher's exact test were used for the comparison. To examine the -related to vulnerability- risk factors for being a frequent ED user, univariate and multivariate logistic regression models were used. RESULTS: We compared 226 frequent users and 173 controls. Frequent users had more vulnerabilities in all five dimensions of the conceptual framework. They were younger, and more often immigrants from low/middle-income countries or unemployed, had more somatic and psychiatric comorbidities, were more often tobacco users, and had more primary care physician (PCP) visits. The most significant frequent ED use risk factors were a history of more than three hospital admissions in the previous 12 months (adj OR:23.2, 95%CI = 9.1-59.2), the absence of a PCP (adj OR:8.4, 95%CI = 2.1-32.7), living less than 5 km from an ED (adj OR:4.4, 95%CI = 2.1-9.0), and household income lower than USD 2,800/month (adj OR:4.3, 95%CI = 2.0-9.2). CONCLUSIONS: Frequent ED users within a universal health coverage system form a highly vulnerable population, when taking into account all five dimensions of a conceptual framework of vulnerability. The predictive factors identified could be useful in the early detection of future frequent users, in order to address their specific needs and decrease vulnerability, a key priority for health care policy makers. Application of the conceptual framework in future research is warranted.

Autonomic prediction of error-related ERP components in perceptual and conceptual tasks in older and younger adults

In studies of cognitive processing, the allocation of attention has been consistently linked to subtle, phasic adjustments in autonomic control. Both autonomic control of heart rate and control of the allocation of attention are known to decline with age. It is not known, however, whether characteristic individual differences in autonomic control and the ability to control attention are closely linked. To test this, a measure of parasympathetic function, vagal tone (VT) was computed from cardiac recordings from older and younger adults taken before and during performance of two attentiondemanding tasks - the Eriksen visual flanker task and the source memory task. Both tasks elicited event-related potentials (ERPs) that accompany errors, i.e., error-related negativities (ERNs) and error positivities (Pe's). The ERN is a negative deflection in the ERP signal, time-locked to responses made on incorrect trials, likely generated in the anterior cingulate. It is followed immediately by the Pe, a broad, positive deflection which may reflect conscious awareness of having committed an error. Age-attenuation ofERN amplitude has previously been found in paradigms with simple stimulus-response mappings, such as the flanker task, but has rarely been examined in more complex, conceptual tasks. Until now, there have been no reports of its being investigated in a source monitoring task. Age-attenuation of the ERN component was observed in both tasks. Results also indicated that the ERNs generated in these two tasks were generally comparable for young adults. For older adults, however, the ERN from the source monitoring task was not only shallower, but incorporated more frontal processing, apparently reflecting task demands. The error positivities elicited by 3 the two tasks were not comparable, however, and age-attenuation of the Pe was seen only in the more perceptual flanker task. For younger adults, it was Pe scalp topography that seemed to reflect task demands, being maximal over central parietal areas in the flanker task, but over very frontal areas in the source monitoring task. With respect to vagal tone, in the flanker task, neither the number of errors nor ERP amplitudes were predicted by baseline or on-task vagal tone measures. However, in the more difficult source memory task, lower VT was marginally associated with greater numbers of source memory errors in the older group. Thus, for older adults, relatively low levels of parasympathetic control over cardiac response coincided with poorer source memory discrimination. In both groups, lower levels of baseline VT were associated with larger amplitude ERNs, and smaller amplitude Pe's. Thus, low VT was associated in a conceptual task with a greater "emergency response" to errors, and at the same time, reduced awareness of having made them. The efficiency of an individual's complex cognitive processing was therefore associated with the flexibility of parasympathetic control of heart rate, in response to a cognitively challenging task.

Improving the use of the nursing process: the impact of charting methodology developed from King's conceptual framework on the use of the nursing process

The purpose of this study was to assess the effects of changing a nursing documentation system, developed from King's Conceptual Framework, on the use of the nursing process. The null hypothesis was that there would be no significant increase in the reflection of the use of the nursing process on the nursing care plan or nurses' notes, as a result of using a nursing documentation system developed using King's Conceptual Framework (1981). The design involved the development of a questionnaire that was used to review health records pre and post implementation of a documentation system developed based on King's Conceptual Framework and Theory of Goal Attainment (1981). A Record Completeness Score was obtained from some of the questions. The null hypothesis was rejected. The results of the study have implications for nursing administration and the evaluation of nursing practice. If the use of a documentation system developed from a conceptual framework increases the reflection of the nursing process on the patient's health record, nursing will have the means to measure patient outcomes/goal attainment. All health care organizations and levels of government are focusing on methods to monitor and control the health-care dollar. In order for nursing to clearly determine the costs associated with nursing care, measurement of patient outcomes/goal attainment will need to be possible. In order to measure patient outcomes/goals attainment nurses will need to be able to collect data on their practice. It will be critical that nursing have a documentation system in place which facilitates the reflection of the nursing process within a theoretical framework.

A conceptual analysis of research literature on teachers' ideology and literacy practices: extending the dialogue through a secondary analysis of high school English as an additional language contexts /

This thesis provides a conceptual analysis of research literature on teachers' ideology and literacy practices as well as a secondary analysis of three empirical studies and the ways in which the ideologies of the English as an Additional Language (EAL) (Street, 2005) teachers in these contexts impact the teaching of literacy in empowering/disabling ways. Several major theoretical components of Cummins (1996, 2000), Gee (1996, 2004) and Street (1995, 2001) are examined and integrated into a conceptual triad consisting of three main areas: power and ideology, validation of students ' cultural and linguistic backgrounds, and teaching that empowers. This triad provides the framework for the secondary analysis of three empirical studies on the ideologies of secondary EAL teachers. Implications of the findings from the conceptual and secondary analyses are examined in light of the research community and secondary school teachers of EAL.

Deception in Sport: A Conceptual and Ethical Analysis

In 1973, Kathleen Pearson offered a pivotal first step into understanding deception in competitive sport and its many intricacies. However, the analysis falls short of truly deciphering this widespread phenomenon. By creating a taxonomy based on Torres (2000) understanding of various types of skills in an athletic contest, a wider array of deceptive practices are encompassed. Once the taxonomy is put forth, weighing the categories against the three-pronged ethical permissibility test established utilizing elements from formalism, conventionalism and broad internalism sheds lights on what deceptive practices should be deemed ethically permissible for use and which tactics should not be a part of an athlete’s repertoire. By understanding which categories of deception are permissible, the most fair and athletically excellent contest can be created between the opposing players of teams.

Automatic evolution of conceptual building architectures

This thesis describes research in which genetic programming is used to automatically evolve shape grammars that construct three dimensional models of possible external building architectures. A completely automated fitness function is used, which evaluates the three dimensional building models according to different geometric properties such as surface normals, height, building footprint, and more. In order to evaluate the buildings on the different criteria, a multi-objective fitness function is used. The results obtained from the automated system were successful in satisfying the multiple objective criteria as well as creating interesting and unique designs that a human-aided system might not discover. In this study of evolutionary design, the architectures created are not meant to be fully functional and structurally sound blueprints for constructing a building, but are meant to be inspirational ideas for possible architectural designs. The evolved models are applicable for today's architectural industries as well as in the video game and movie industries. Many new avenues for future work have also been discovered and highlighted.

Conceptual Analysis of Web 2.0 Technology Use to Enhance Parent–School Relationships

Parent–school relationships contribute significantly to the quality of students’ education. The Internet, in turn, has started to influence individuals’ way social communication and most school boards in Ontario now use the Internet to communicate with parents, which helps build parent–school relationships. This project comprised a conceptual analysis of how the Internet enhances parent–school relationships to support Ontario school board administrators seeking to implement such technology. The study’s literature review identified the links between Web 2.0 technology, parent–school relationships, and effective parent engagement. A conceptual framework of the features of Web 2.0 tools that promote social interaction was developed and used to analyze websites of three Ontario school boards. The analysis revealed that school board websites used static features such as email, newsletters, and announcements for communication and did not provide access to parents for providing feedback through Web 2.0 features such as instant messaging. General recommendations were made so that school board administrators have the opportunity to implement changes in their school community with feasible modifications. Overall, Web 2.0-based technologies such as interactive communication tools and social media hold the most promise for enhancing parent–school relationships because they can help not only overcome barriers of time and distance, but also improve the parents’ desire to be engaged in children’s education experiences.
