Computers in Artificial Intelligence Education     

JIŘI LAŽANSKÝ  VLADIMÍR MAŘÍK  OLGA ŠTĚPÁNKOVÁ 《European Journal of Engineering Education》1992,17(2):143-149

Both the origin and development of artificial intelligence (AI) are connected with the origin and development of computers. Computers play a very important role in engineering education. AI influences such disciplines like CAD, CASE, CAE, and others. The specific experience concerning AI education at a technical university has been gathered in this paper. There is stressed need of good balance between theoretical background and individual training with computers as well as importance of personal experience in solving practical AI.  相似文献   

Metaphors we’re colonised by? The case of data-driven educational technologies in Brazil     

Giselle Martins dos Santos Ferreira  Luiz Alexandre da Silva Rosado  Márcio Silveira Lemgruber  Jaciara de Sá Carvalho 《Learning, Media and Technology》2020,45(1):46-60

ABSTRACT

This article discusses issues concerning the spread of data-driven educational technologies in Brazil. Here, as elsewhere, educational technology continues to be promoted optimistically as the bearer of a panacea for historically-rooted social problems. Whilst some of these technologies have indeed contributed to important widening-participation programmes in the last two decades, widespread advocacy of technological ‘solutionism’, reflected in gradually stronger policy demands for efficiencies to be improved through ‘innovation’, has supported a relentless marketisation of the country’s educational systems. As transnational corporations position themselves to take control of key areas of these systems, threatening to restructure the whole sector, data-driven educational technologies provide the latest example in a series of ‘new’ ideas offered in an ever-expanding market. Based on the notion of ‘conceptual metaphors’, which encapsulate specific ways of perceiving, thinking and relating with the world, this article examines key metaphors underpinning discourses surrounding data-driven educational technologies in Brazil. In particular, the article analyses ways in which these specific metaphors may be promoting perspectives that ignore difference and obscure broader questions concerning education, thus contributing to the reproduction of previously existing problems and supporting new forms of colonisation.  相似文献   

Exercise but not metformin improves health-related quality of life and mood states in older adults with type 2 diabetes     

Liliana C. Baptista  Aristides M. Machado-Rodrigues  Raul A. Martins 《European Journal of Sport Science》2017,17(6):794-804

The aim of this cohort study is to analyse the effect of three types of treatment: (i) exercise training with multicomponent exercise (E); (ii) pharmacologic treatment with oral hypoglycaemic drug – metformin (M); and (iii) a combined therapy – exercise and metformin (E?+?M) on health-related quality of life (HRQoL) and mood states in older adults with type 2 diabetes (T2D) with comorbidity in an early stage of the disease. Participants (n?=?284) underwent 1 of the following 3 conditions: (i) E (n?=?59) trained three times/week; (ii) M (n?=?30) used 850?mg of metformin twice daily; and (iii) E?+?M (n?=?195) combined exercise and metformin. Furthermore, participants completed baseline and 2-year follow-up evaluations including a Shortform Health Survey 36, Profile of Mood States – Short-form, the health history questionnaires, anthropometric, and blood biochemistry. E and E?+?M revealed improved mood states, with large effect size on the vigour domain, and moderate effect size in the anger and total mood disturbance (TMD) domains (P?<?0.05), in comparison with the M group. After 24 months’ intervention, the E and E?+?M groups perceived better physical and mental HRQoL than the M group. The M group unchanged HRQoL domains (P?>?0.05). Metformin had no significant effect on the self-referred HRQoL in T2D participants aged above 60 years, in an early stage of the disease. The E and E?+?M were the most effective long-term therapies to improve mood states and HRQoL in older adults with T2D.  相似文献   

Cinema Demand in Spain: A Cointegration Analysis   总被引：4，自引：3，他引：1  

VÍctor FernÁndez Blanco  JosÉ F. BaÑos Pino 《Journal of Cultural Economics》1997,21(1):57-75

In this paper we explain the decline in cinema attendance in Spain since 1968. We use a cointegration analysis to estimate an individual demand function for cinema, with annual data and in terms of average attendance per inhabitant. We find that cinema is a luxury good and that its demand is elastic with respect to its price. We also show that television acts as a deterrent with regard to cinema attendance. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献   

Mirroring the Media: The Relationship Between Media Consumption,Media Internalization,and Profile Picture Characteristics on Facebook     

Sanja Kapidzic  Nicole Martins 《广播与电子媒介杂志》2015,59(2):278-297

Social cognitive theory suggests that stereotypes of attractiveness from mainstream media may function as models for online profile pictures. The present study explores the relationship between media consumption, internalization, and body-ism, clothing, and gaze through a content analysis of the Facebook profile pictures of 288 students, and a survey to assess their media consumption and internalization. The relationship between magazine exposure and pictures was mediated by internalization: magazine readers who internalized media ideals were more likely to select pictures showing their body in revealing clothing. Television viewing had a direct effect on picture selection, but was not mediated by internalization.  相似文献   

Nothing to Fear? An Analysis of College Students' Fear Experiences With Video Games     

Teresa Lynch  Nicole Martins 《广播与电子媒介杂志》2015,59(2):298-317

This study presents the results of a survey of 269 undergraduate students conducted to examine fright experiences caused by video games. Over half of the participants reported game-induced fear. Sex, sensation-seeking, and empathy all emerged as important individual differences in terms of enjoyment of frightening content, consumption of frightening content, and frequency of fright experience. Interactivity and presentations of realism also predicted fear. This work identifies titles, stimuli, and features that caused fright experience.  相似文献

Understanding the Internet banking adoption: A unified theory of acceptance and use of technology and perceived risk application     

Carolina Martins  Tiago Oliveira  Aleš Popovič 《International Journal of Information Management》2014

Understanding the main determinants of Internet banking adoption is important for banks and users; our understanding of the role of users’ perceived risk in Internet banking adoption is limited. In response, we develop a conceptual model that combines unified theory of acceptance and use of technology (UTAUT) with perceived risk to explain behaviour intention and usage behaviour of Internet banking. To test the conceptual model we collected data from Portugal (249 valid cases). Our results support some relationships of UTAUT, such as performance expectancy, effort expectancy, and social influence, and also the role of risk as a stronger predictor of intention. To explain usage behaviour of Internet banking the most important factor is behavioural intention to use Internet banking.  相似文献
