AbstractThis study had three goals: to analyze gender differences in victimization, perception of school violence, and social behaviour; to study the relations between these variables; and to identify variables predicting victimization. A correlational methodology was employed, and three assessment instruments were administered. The sample was made up of 178 participants aged between 13 and 15 years. The results yielded no gender differences in victimization; however, females perceived more verbal abuse and performed more behaviours of help-collaboration, whereas males scored higher in negative social behaviours (aggressiveness-stubbornness, dominance, apathy-withdrawal). The bullying victims of both sexes had a high perception of school violence; moreover, victimized males performed few behaviours of help-collaboration and assurance-firmness, whereas victimized females displayed many behaviours of social anxiety. Six variables predicted victimization: high perception of violence through information and communication technologies, high social anxiety, lower age, little aggressive behaviour, high perception of verbal abuse, and few behaviours of help-collaboration. 相似文献

In a series of related experiments, we studied associative phenomena in snails (Helix aspersa), using the conditioning procedure of tentacle lowering. Experiments 1A and 1B demonstrated a basic conditioning effect in
which the pairing of an odor (apple) as the conditioned stimulus (CS) with the opportunity to feed on carrot as the unconditioned
stimulus (US) made snails exhibit increased levels of tentacle lowering in the presence of the CS. Experiments 2 and 3 showed
that the magnitude of the conditioning was reduced when snails were exposed to the CS prior to the conditioning trial (a latent
inhibition effect). Experiment 4 examined the effects produced by pairing a compound CS (apple—pear) with food presentations
and demonstrated the existence of an overshadowing effect between the two odors. Experiment 5 revealed that pairing one CS
with another previously conditioned stimulus increased tentacle lowering to the new CS (a second-order conditioning effect).
Finally, Experiment 6 showed that pairing two odors prior to conditioning of one of them promoted an increase in tentacle
lowering in response to the other (a sensory preconditioning effect). The results are discussed in terms of an associative
analysis of conditioning and its implications for the study of cognition in invertebrates. 相似文献

Abstract The aim of this study was to compare equations for estimating percentage body fat from skinfold thickness in elite sport climbers by assessing their agreement with percentage body fat measured using dual-energy X-ray absorptiometry (DXA). Skinfold thickness was measured in a convenience sample of 19 elite sport climbers [9 women and 10 men; mean age 31.2 years (s = 5.0) and 28.6 years (s = 3.6), respectively]. Percentage body fat was estimated using 17 different equations, and it was also measured by DXA. A significant inter-methods difference was observed for all equations, except for Durnin's equation in men (inter-methods difference: ?0.57% and ?0.29%; 1.96 s: 5.56 and 5.23 for Siri's and Brozek's equation, respectively) and women (inter-methods difference: ?0.67% and ?1.29% for Siri's and Brozek's equation, respectively), and for Wilmore's equation using Siri's body fat equation in women (inter-methods difference: ?1.86%). In women, the limits of agreement were lower when using Durnin's equation compared with Wilmore's equation (1.96 s: 3.86% and 5.13%, respectively). In conclusion, of the 17 studied equations, Durnin's equation was the most accurate in estimating percentage body fat in both male and female elite climbers. Therefore, Durnin's equation could be used to assess percentage body fat in elite sport climbers if more accurate methods are not available. The generalizability of the results is limited by the fact that the sample was not selected at random. 相似文献

Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as “laboratory monitors.” A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area 相似文献

This work compares the results of three assessment systems used in two Spanish universities (the Universidad Politécnica de Madrid and the Universidad Católica de Ávila): the traditional system based on final examinations, continuous assessment with periodic tests and a proposed system (specially designed for heterogeneous student bodies) orientated towards motivating students. This third system involved dividing the syllabus into two different parts: a common core assessed by multiple choice tests, and a specialisation assessed by a literature review, the writing of an article and an oral presentation. The latter skills are highly valued by employers. The proposed system led to a greater pass rate than that achieved by students taking similar courses assessed by the more conventional systems. In addition, the results show that involving students in the assessment process increases their participation in their studies and generates a feeling of satisfaction and justice. 相似文献
