This article investigates how students reason and argue to make sense of fictional literature. Excerpts from students’ talk are analysed using the concepts categorisation, particularisation and recontextualisation, and interpreted from a socio-cultural, dialogical perspective. The analyses show that the students’ arguments oscillate between personal experience and the novel, and between categorising and particularising perspectives. The subject relevance of talk that lies between everyday and scientific talk, and between personal and analytic readings, is revealed. The bridging of different readings, different language practices, and different learning contexts is discussed.  相似文献

Neurodegen erative disorders such as Alzheimer’s disease (AD) are increasingly threatening public health. Most animal models of AD consist of transgenic mice that are usually housed singly or in unisexual groups in small barren cages. Such restricted environments, however, prevent the mice from showing a variety of speciesspecific behaviors and consequently may constrain comprehensive behavioral phenotyping. On the other hand, allowing the animals to freely organize their lives in a spacious physically and socially enriched environment makes behavioral phenotyping laborious and time consuming. Radio frequency identification (RFID) using a network of antennae and small glass-coated transponders labeling each individual allows for gathering spatiotemporal information about a large number of individuals in parallel. The aim of this project was to use the RFID technique to facilitate the characterization of mice carrying a genetic disposition to develop AD-like pathology and of their wild-type conspecifics in a spacious seminaturalistic environment.  相似文献

Abstract : C. S. Lewis' views on sexuality and the relationship between men and women changed radically through his relationship with Joy, his friend and later wife. Lewis makes a sharp distinction between love and friendship in his writings. This article shows how his concrete experience of love and grief with Joy transformed his understanding of relationships between men and women, and, eventually, the meaning of being human and its implications for Christianity.  相似文献

One 9‐year‐old child was taught conditional discriminations between dictated names in Spanish and their corresponding pictures across three stimulus sets while her 10‐year‐old brother observed. Posttests revealed the emergence of symmetry relations in the form of oral naming skills by both children.  相似文献

Social disorganization theory suggests that certain school-level indictors of disorder may be important predictors of bullying-related attitudes and behaviors. Multilevel analyses were conducted on bullying-related attitudes and experiences among 22,178 students in 95 elementary and middle schools. The intraclass correlation coefficients indicated that 0.6–2% of the variance in victimization, 5–10% of the variance in retaliatory attitudes, 5–6% of the variance in perceptions of safety, and 0.9% of the variance in perpetration of bullying was associated with the clustering of students within schools. Although the specific associations varied somewhat for elementary schools as compared to middle schools, the hierarchical linear modeling analyses generally suggested that school-level indicators of disorder (e.g., student–teacher ratio, concentration of student poverty, suspension rate, and student mobility) were significant predictors of bullying-related attitudes and experiences. Student-level characteristics (i.e., sex, ethnicity, status in school) were also relevant to students’ retaliatory attitudes, perceptions of safety, and involvement in bullying. Implications for school-based research and violence prevention are provided.  相似文献

A brief overview of the person orientation is provided. It is then argued that research in community psychology, similar to every other field in psychology, has mainly focused on variables, not individuals. Suggestions are provided for how the person orientation can be applied to understanding settings and environments as well as the theoretical and methodological contributions community psychologists can make to further person oriented methods.  相似文献

The present study examined whether written syllable units are perceived in first steps of letter string processing. An illusory conjunction experiment was conducted while event-related potentials were recorded. Colored pseudowords were presented such that there was a match or mismatch between the syllable boundaries and the color boundaries. The results showed that congruent stimuli for which the syllable and color boundaries coincided produced a greater positive-going waveform than incongruent stimuli for which the syllable and color boundaries did not coincide. This syllable–color congruency effect was observed to occur both prior to 100 ms, and in a time window commencing at 150 ms. This finding suggests that syllable units are perceived in the initial steps of French visual word processing. Moreover, this study underlines the specificity of the illusory conjunction paradigm as a relevant and powerful tool of investigation of sublexical units that are automatically evoked from word perception.  相似文献

This study contributes to the growing body of knowledge about spirituality and life transitions. Through qualitative investigation, 9 young women in professional education programs described their definition of spirituality, their spiritual activities, and how they used their spirituality to cope with life transitions as they prepared to enter the workforce. These women viewed spirituality as including connectedness and a special relationship with a Being outside of themselves. Their spiritual activities were private and non‐traditional (e.g., meditation, prayer, being in nature), and most of them reported that their spirituality helped them deal with their life transition.  相似文献

We report on data provided by a nationwide panel of 23 infant mental health (IMH) experts who provided numerical ratings of the relative importance of 143 competencies desirable for licensed mental health therapists working with infants/children birth to 5 years of age and their families/caregivers. The competencies were developed based on prior state and national efforts and our own experience in training IMH therapists. The competencies were grouped conceptually into seven areas: (a) Normal infant and toddler development; (b) Atypical development (perturbations in development); (c) Emotional/behavioral disorders in infants and young children; (d) Assessment; (e) Intervention; (f) Community resources and referrals; and (g) Organization, communication, and collaboration. We calculated means, SDs, 95% confidence intervals to rank order each competency. We conducted reliability analyses and tested for mean differences in ratings for the seven areas. Interrater and intraclass correlations were modest, likely the result of restriction of range in the ratings. The seven areas showed high levels of internal consistency and, with few exceptions, did not significantly differ in the means of their ratings. The utility of the competencies are discussed as a framework for training and professional development for IMH clinicians.  相似文献

Academic theories of aggression can be dichotomized as expressive (in which aggression results from a failure of self control) or instrumental (in which aggression represents the exercise of control over others). We propose that the two sexes hold a parallel distinction in their social representations of aggression; women subscribe to an expressive model, men to an instrumental model. A 20-item questionnaire was generated by systematic comparison of the two theories with respect to their differential predictions concerning perceived social value, proximate causes, relevant emotions and congnitions, form, aim, social facilitators, and reputational aspects of aggression. Factor analysis indicated a first factor of expressive-instrumental aggression on which all items had significant loadings. A significant correlation (.46) was found between gender and questionnaire score confirming the hypothesis. The notion of gender-specific social representations is discussed in terms of its ability to coherently interpret patterns of differences in aggression found in experimental and observational studies.  相似文献
