Some practical approaches to a course on paraconsistent logic for engineers     

Germano Lambert-Torres  Carlos Henrique Valerio de Moraes  Maurilio Pereira Coutinho  Helga Gonzaga Martins  Luiz Eduardo Borges da Silva 《European Journal of Engineering Education》2017,42(6):1296-1308

This paper describes a non-classical logic course primarily indicated for graduate students in electrical engineering and energy engineering. The content of this course is based on the vision that it is not enough for a student to indefinitely accumulate knowledge; it is necessary to explore all the occasions to update, deepen, and enrich that knowledge, adapting it to a complex world. Therefore, this course is not tied to theoretical formalities and tries at each moment to provide a practical view of the non-classical logic. In the real world, the inconsistencies are important and cannot be ignored because contradictory information brings relevant facts, sometimes modifying the entire result of the analysis. As consequence, the non-classical logics, such as annotated paraconsistent logic – APL, are efficiently framed in the approach of complex situations of the real world. In APL, the concepts of unknown, partial, ambiguous, and inconsistent knowledge are referred not to trivialise any system in analysis. This course presents theoretical and applicable aspects of APL, which are successfully used in decision-making structures. The course is divided into modules: Basic, 2vAPL, 3vAPL, 4vAPL, and Final Project.  相似文献   

Improving teaching and learning of computer programming through the use of the Second Life virtual world     

Micaela Esteves  Benjamim Fonseca  Leonel Morgado  Paulo Martins 《British journal of educational technology : journal of the Council for Educational Technology》2011,42(4):624-637

The emergence of new technologies such as three‐dimensional virtual worlds brings new opportunities for teaching and learning. We conducted an action research approach to the analysis of how teaching and learning of computer programming at the university level could be developed within the Second Life virtual world. Results support the notion that it is possible to use this environment for better effectiveness in the learning of programming. The main results are the identification of problems hampering the teacher's intervention in this virtual world and the detection of solutions for those problems that were found effective to the success in using this environment for teaching/learning computer programming.  相似文献   

Do inequalities in parents’ education play an important role in PISA students’ mathematics achievement test score disparities?   总被引：1，自引：0，他引：1  

Lurdes Martins  Paula Veiga 《Economics of Education Review》2010

This paper measures and decomposes socioeconomic-related inequality in mathematics achievement in 15 European Union member states. Data is taken from the 2003 wave of the OECD Programme for International Student Assessment (PISA). There is socioeconomic-related inequality in mathematics achievement, favoring the higher socioeconomic groups in each country. There are important differences among countries. The inequality is higher in Germany, Greece, Great Britain, Belgium, and Portugal and is lower in Sweden and Finland. Socioeconomic factors represent between 14.9% and 34.6% of the overall inequality in education.  相似文献   

The geometric curvature of the spine during the sirshasana,the yoga’s headstand     

Mário Hebling Campos  Nayane Martins Giraldi  Paulo Gentil  Claudio Andre Barbosa de Lira  Carlos A. Vieira  Marcelo Costa de Paula 《Journal of sports sciences》2017,35(12):1134-1141

This study analysed the behaviour of the geometric curvature of the spine during sirshasana. The position of dorsal retroreflective markers was computed via stereophotogrammetric analysis in six males and five females (29.4 ± 8.8 years, 63.0 ± 11.4 kg, 1.66 ± 0.08 m [average ± standard deviation]). The spinal points were projected onto the sagittal and frontal planes of the trunk, a polynomial was fitted to the data and the two-dimensional geometric curvature was quantified. The inferior lumbar lordosis decreased compared to the orthostatic position and gait, which may favour the posterior protrusion of the lumbar spinal nucleus pulposus in people with posterior herniation. The lateral deviation at the middle of the thoracic spine increases during sirshasana, which may reflect increased difficulties for postural control and spinal loads. It could be useful for promoting positive spinal structural and functional chronic adaptations for healthy participants, if the yoga programme is carefully planned and the spinal alignment is carefully monitored during a headstand. However, it may aggravate some spinal diseases, especially scoliosis.  相似文献   

The start-up,evolution and impact of a research group in a university developing its knowledge base     

Horta  Hugo  Martins  Rui 《Tertiary Education and Management》2014,20(4):280-293

This article focuses on the understudied role of research groups contributing to develop the knowledge base of developing universities in regions lagging behind in human, financial and scientific resources. We analyse the evolution of a research group that, in less than 10 years, achieved worldwide recognition in the field of microelectronics, with an impact on both engineering research and teaching activities at the University of Macau. Our analysis concludes that voluntarism and loose organizational structures from the start stimulate the development of solid scientific agendas and institutional identity, and that counter-intuitive policies, including academic inbreeding, may also be needed and unavoidable in this effort. The use of these counter-intuitive policies and their effects, however, can be mitigated by transforming education to highlight high levels of internationalization and quality standards with measurable outcomes. This requires the committed involvement of research group leaders in both research and education. Lastly, another key component of university development may lie in hiring and giving freedom to young promising scholars with the will and drive to lead and act.  相似文献

Self-training through the Internet     

António S. C. Fernandes  Maria João Martins 《European Journal of Engineering Education》2001,26(2):169-177

The development of five courses, aimed at advanced engineering training, using the Internet, is described in this paper. A European consortium was responsible for the development, implementation and testing of the courses through the organization of virtual classes on the Internet. An important outcome was the definition of the training service characteristics, which led to the development of a quality system based on four fundamental concepts: credit, accreditation, certification and qualification. Professionals of several age groups and industrial sectors with different expectations as well as engineering students attended pilot virtual classes. From the trainee's side, we report on how the training opportunity was received and how the training service provided was felt. The main project successes and a few weak points and a number of important recommendations are listed for future reference.  相似文献   

Speech acts by mother and child: Determining their nature and form     

Josie Bernicot  Judith Comeau  Helga Feider 《European Journal of Psychology of Education - EJPE》1993,8(1):35-50

The goal of the present study was to determine to what extent the psychological, social, and cultural features of the communication situation affect the production of speech acts during an interaction between an adult and a child. Variations in the nature of the speech acts produced (assertive, directive, expressive, and commissive) and in their linguistic form (imperative, declarative, interrogative, and exclamative) were studied in relation to three variables describing the communication situation: (a) a psychological variable, the mother’s child-raising style (coercive or inductive) which was assessed using a questionnaire on parental control behavior (MCCP, Tessier, Pilon, & Fecteau, 1985); (b) a social variable, the social role of the speaker (mother or child); and (c) a cultural variable, the origin of the dialogue partners (French or Canadian). For each cultural sample, 15-minute dialogues were recorded while 10 pairs of mothers in interaction with their 5 and 6 year old daughters performed a task involving drawing on a computer. The results suggest that for children between the ages of 5 and 6, the production of speech acts is mainly controlled by the social characteristics of the communication situation rather than by its psychological and cultural features. Mothers appear instead to be sensitive to all three kinds of factors. Moreover, the four types of speech acts were found to differ in their frequency of occurrence, linguistic form, and reaction to the psychological, social, and cultural characteristics of the communication situation. Finally, this study suggests that the effects of these characteristics on speech act production are not uniform, but vary according to the index under consideration.  相似文献   

Career adaptability and associations with personality traits and pathological traits utilizing network analysis     

Gonçalves  André Pereira  Martins  Gustavo Henrique  Salvador  Ana Paula  Machado  Gisele Magarotto  Carvalho  Lucas de Francisco  Ambiel  Rodolfo Augusto Matteo 《International Journal for Educational and Vocational Guidance》2021,21(2):379-394

This study investigated relationships between career adaptability and personality and pathological traits using the network analysis approach. We administered CAAS, BFI-2-S, and IDCP-2 to 630 working adults. We observed positive associations between personality and career adaptability and negative associations between pathological traits and career adaptability. This paper contributes to the understanding of the associations between career adaptability and Big Five personality traits and pathological traits. We found stronger associations between career adaptability and personality traits as compared to pathological traits. Our findings suggest that Neuroticism and Conscientiousness contribute more to adaptation to professional development tasks than do pathological traits.
