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

Research into violence in schools has been growing steadily at an international level, and has shown high degrees of violence at various different levels. Given the seriousness of the problem, finding ways of responding to this issue in schools becomes an imperative for educationists. In this article, we engage with this problem by defending the view that whilst violence might be endemic in schools, there are also real possibilities for working towards different ways of being in relationship in schools. Firstly, we discuss Galtung’s understanding of violence and peace, paying particular attention to his concepts of structural and cultural violence, peacekeeping, peacemaking and peacebuilding. Secondly, we connect Galtung’s notions of peacemaking to Buber’s philosophy of dialogue, in order to make a case for an ‘epistemological shift’ which might enable individuals and communities to achieve ‘peace’. Finally, we direct our argument to the education context and put forward some concrete proposals for peacemaking in schools. 相似文献

Purpose: To investigate the effect of sodium bicarbonate (NaHCO3) on performance and estimated energy system contribution during simulated taekwondo combat. Methods: Nine taekwondo athletes completed two experimental sessions separated by at least 48?h. Athletes consumed 300?mg/kg body mass of NaHCO3 or placebo (CaCO3) 90?min before the combat simulation (three rounds of 2 min separated by 1 min passive recovery), in a double-blind, randomized, repeated-measures crossover design. All simulated combat was filmed to quantify the time spent fighting in each round. Lactate concentration [La?] and rating of perceived exertion (RPE) were measured before and after each round, whereas heart rate (HR) and the estimated contribution of the oxidative (WOXI), ATP (adenosine triphosphate)-phosphocreatine (PCr) (WPCR), and glycolytic (W[ La? ]) systems were calculated during the combat simulation. Results: [La?] increased significantly after NaHCO3 ingestion, when compared with the placebo condition (+14%, P?=?0.04, d?=?3.70). NaHCO3 ingestion resulted in greater estimated glycolytic energy contribution in the first round when compared with the placebo condition (+31%, P?=?0.01, d?=?3.48). Total attack time was significantly greater after NaHCO3 when compared with placebo (+13%, P?=?0.05, d?=?1.15). WOXI, WPCR, VO2, HR and RPE were not different between conditions (P?>?0.05). Conclusion: NaHCO3 ingestion was able to increase the contribution of glycolytic metabolism and, therefore, improve performance during simulated taekwondo combat. 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

In four carefully selected samples of 8- to 10-year old children with dyslexia (but age adequate arithmetic skills), dyscalculia (but age adequate reading skills), dyslexia/dyscalculia and controls a domain-general deficit in rapid automatized naming (RAN) was found for both dyslexia groups. Dyscalculic children exhibited a domain-specific deficit in rapid naming of quantities. This finding is in line with recent assumptions that dyscalculia is associated with a neurobiological deficit in the processing of numerosities. In the dyslexia/dyscalculia group, RAN deficits were additive, that is, the dyslexia/dyscalculia group exhibited the sum of the deficits found in the dyslexia only and dyscalculia only groups. This finding suggests that the cognitive bases of dyslexia and dyscalculia are independent from each other. Within the naming speed paradigm no differential impact of special demands on the executive functions inhibition and shifting was found for any of the four groups. 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
