Brain adaptation to the type of informationthat is processed has been documented inseveral conditions in animals and humans.Illiteracy due to social reasons is a goodsource of information to investigate theadaptation mechanisms to the formal knowledgeof written language. In this paper, a series ofstudies addressing this topic are reviewed.Illiterate subjects and their carefullyselected controls were compared in severalexperimental conditions. It is concluded thatschooling and in particular the knowledge oforthography introduces in the brain newstrategies for information processing thatmanifest themselves in task performance, inbrain activation studies and in anatomicalstudies. 相似文献

The aim of this study was to investigate relations between lexical-semantic processing and two components of reading: visual word recognition and reading comprehension. Sixty-eight children from private schools in Porto Alegre, Brazil, from 7 to 12 years, were evaluated. Reading was assessed with a word/nonword reading task and a reading comprehension task. Lexical-semantic processing was evaluated with a semantic priming experiment. Correlations were conducted in order to examine the relations between semantic priming effects (SPEs) and performance in reading tasks. Regression analyses were performed to test the hypothesis that word reading mediates the relation between semantic priming and reading comprehension. The results showed that SPEs correlated with both word reading and reading comprehension measures. Additionally, partial mediation by word reading was found for the prediction of reading comprehension by SPEs. The results are discussed in the context of reading models and other studies relating semantic priming and reading measures. 相似文献

This article claims that Freire’s work offers an important ground for a potential theory of intercultural ethics and, for that purpose, examines his ideas at different levels: (1) the ontological; (2) the ideological; (3) the political; (4) languages and languaging; and (5) cultural identity and diversity. Freire never used the word ‘intercultural’, although it is suggested here that this is due to the fact that terminology related to cultural diversity has changed over time and in his day this term was not yet common currency. Moreover, Freire uses more often the term ‘multiculturalidade’ rather than ‘multiculturalismo’ (multiculturalism) since the former suffix ‘-dad(e)’ has a different meaning which refers to the ontological nature of the condition and is more usual in both Portuguese and Spanish. This article also argues for the relevance of a theory of intercultural ethics in the contemporary world that imprints (inter)cultural flexibility on the current hermeneutics of ethics while preventing excessive abuses on behalf of relativism, dogmatism, essentialism and fundamentalism. 相似文献

Abstract educational practices are to be based on proven scientific knowledge, not least because the function science has to perform in human culture consists of unifying practical skills and general beliefs, the episteme and the techne (Amsterdamski, 1975, pp. 43–44). Now, modern societies first of all presuppose regular and standardized ways of organizing both our concepts and our institutions. The explanatory schemata resulting from this standardization tend to destroy individualism and enchantment. But mathematics education is in fact the only place in which to treat the human subject’s relationship with mathematics. And that is what mathematics education is all about: make the human subject grow intellectually and as a person by means of mathematics. At first sight, mathematics, in its formal guise, seems the opposite of philosophy, because philosophy constructs concepts (meanings), whereas mathematics deals with extensions of concepts (sets). We shall, however, turn this problem into an instrument, using the complementarity of intensions and extensions of theoretical terms as our main device for discussing the relationship between philosophy and mathematics education. The complementarity of the “how” and the “what” of our representations outlines, in fact, the terrain on which epistemology and education are to meet. 相似文献

‘Language death’ is an undeniable phenomenon of our modern times as languages have started to disappear at an alarming rate. This has led linguists, anthropologists, philosophers and educationists to engage with this issue at various levels in an attempt to try to understand the decline in this rich area of human communication and culture. In this article I refer to some interesting and innovative educational projects in the Amazon region of Brazil, which are revitalizing local languages, cultures and communities. I analyse these projects in the light of some of Paulo Freire’s ideas, particularly his views on conscientization, praxis and contextualization, and will argue that these educational ventures might be viewed as useful templates for other countries and peoples seeking to reverse or avoid ‘language-culture’ death. 相似文献

Attaching elastic tubes (ETs) to resistance training machines can affect the exercise load profile. The purpose of this study was to assess the training effects of added ETs, which were strategically attached to provide additional loads only during the deceleration phase of the knee extension exercise. Twenty-two healthy participants, assigned to either an experimental group (with ETs) or a control group (without ETs), participated in a 12-week strength-training program using a knee extension exercise machine. The acceleration effects were quantified and a method of attaching the ETs to the knee extension machine was developed. The effects of the added ETs were analysed by testing dynamic and isometric maximum contractions at four knee flexion angles (10°, 30°, 50°, and 80°). Analyses of covariance with the initial values as the covariate were used to examine the ET effects. A greater increase in isometric maximum strength was found in the experimental group than in the control group at knee flexion angles of 10° [effect size (ES) = 2.25] and 30° (ES = 1.18). No significant difference in the dynamic maximum strength was found between the groups. The use of ETs increased strength at smaller knee flexion angles with quadriceps that were relatively short. 相似文献

The detection of communities in large social networks is receiving increasing attention in a variety of research areas. Most existing community detection approaches focus on the topology of social connections (e.g., coauthor, citation, and social conversation) without considering their topic and dynamic features. In this paper, we propose two models to detect communities by considering both topic and dynamic features. First, the Community Topic Model (CTM) can identify communities sharing similar topics. Second, the Dynamic CTM (DCTM) can capture the dynamic features of communities and topics based on the Bernoulli distribution that leverages the temporal continuity between consecutive timestamps. Both models were tested on two datasets: ArnetMiner and Twitter. Experiments show that communities with similar topics can be detected and the co-evolution of communities and topics can be observed by these two models, which allow us to better understand the dynamic features of social networks and make improved personalized recommendations. 相似文献

The purpose of this study was to determine the physiological, anthropometric, performance, and nutritional characteristics of the Brazil Canoe Polo National Team. Ten male canoe polo athletes (age 26.7 ± 4.1 years) performed a battery of tests including assessments of anthropometric parameters, upper-body anaerobic power (Wingate), muscular strength, aerobic power, and nutritional profile. In addition, we characterized heart rate and plasma lactate responses and the temporal pattern of the effort/recovery during a simulated canoe polo match. The main results are as follows: body fat, 12.3 ± 4.0%; upper-body peak and mean power, 6.8 ± 0.5 and 4.7 ± 0.4 W · kg(-1), respectively; 1-RM bench press, 99.1 ± 11.7 kg; peak oxygen uptake, 44.3 ± 5.8 mL · kg(-1) · min(-1); total energy intake, 42.8 ± 8.6 kcal · kg(-1); protein, carbohydrate, and fat intakes, 1.9 ± 0.1, 5.0 ± 1.5, and 1.7 ± 0.4 g · kg(-1), respectively; mean heart rate, 146 ± 11 beats · min(-1); plasma lactate, 5.7 ± 3.8 mmol · L(-1) at half-time and 4.6 ± 2.2 mmol · L(-1) at the end of the match; effort time (relative to total match time), 93.1 ± 3.0%; number of sprints, 9.6 ± 4.4. The results of this study will assist coaches, trainers, and nutritionists in developing more adequate training programmes and dietary interventions for canoe polo athletes. 相似文献
