狗狗布鲁娜的遗赠

那天是1997年3月13日。我当时把车停进车库,然后走进厨房。那一刻,我震惊得完全哑口无言。窝在桌子上一个小花篮里的是一只可爱的杏色小贵宾犬,它直愣愣地盯着我看。毫无疑问,我对它一见钟情,而这种爱意一直延续,直至瞑目,直至永远。布鲁娜从那天起就进入了我的生活。那时候,     

Phonological working memory, phonological awareness and language in literacy difficulties in Brazilian children

One of the most usual flaws that lead to literacy disability regards cognitive difficulties and alterations some children present in the literacy process. Many studies have found alterations in phonological processing, more specifically in phonological working memory (PWM) and phonological awareness (PA). Therefore, our aim was to identify alterations in skills of phonological working memory, phonological awareness and language (semantic, syntactic and phonological aspects) of Brazilian children with literacy disabilities (age 7–8). They were divided into two groups: (1) Group of Normal Literacy (NL); and (2) Group With Literacy Disabilities (LD). The evaluation comprised tests that assessed general cognitive functions and the skills at stake. The LD presented a poorer performance than the NL in the skills of PWM, PA and language aspects. The factor analysis showed that these skills prevailed in differentiating the groups. Thus, children with literacy disabilities presented deficits in phonological processing and language. These deficits seem to be a result of alterations of the phonological representations and poor language skills that are prior to the literacy period. Consequently, we believe that the early identification of these alterations can be very useful for the prevention of future literacy problems.     

The advance of research and evaluation skills by EPs: implications for training and professional development

Research and evaluation has become increasingly important in many professions, including educational psychology, particularly as the profession moves to becoming more evidence‐based in its practice. The recent move to a three year doctoral programme in England, Wales and Northern Ireland may be viewed as a positive one in developing research skills, although it is also crucial to consider what could be done to extend the research skills of those already qualified. Lessons may be learned by looking to clinical psychology and some of the health professions. Finally, some further implications for the training and professional development of Educational Psychologists (EPs) in the UK are considered.     

Home Visits: How Do They Affect Teachers’ Beliefs about Teaching and Diversity?

Based on Bronfenbrenner’s ecological systems theory, this qualitative study examined the impact of home visits on a group of six Head Start educators. Each participant conducted two home visits. For the first home visit, participants were not provided any guidance. On the second visit, participants were provided a handout with questions intended to guide their visit. The participants were asked to document, in a reflective journal, their feelings and attitudes toward the children’s families on two visits. Additionally, participants commented on their teaching beliefs and practice as impacted by their home visit. Results of the study indicated that home visits enabled participants to see the families and children that they work with from a different and more positive perspective. The guided home visit questions allowed participants to better understand children and their families from historical and cultural perspectives. Also, participants were better able to create a more multicultural learning environment and lesson plans for their children.     

Teaching values in physical education classes: the perception of Brazilian teachers

The contribution of Physical Education (PE) and School Sport to learning of values has been identified by teachers and researchers. However, we know little about how that teaching takes place during classes. This study aimed to understand the perceptions of teachers on teaching values in their classes and to analyse the conception of values that have guided their professional intervention. To do this, a qualitative study was conducted with a sample of three teachers, using class observations and interviews with the teachers as research tools. For all these teachers, teaching values is a central goal of PE classes; for two of the teachers, it is the main goal. Because of this conviction, their pedagogies prioritize the teaching of moral values over others that can be taught in PE. A belief in the possibility of teaching values in the classroom is part of the habitus of the PE teacher; it can sometimes be characterized as an illusio. For these reasons, teachers can set unrealistic expectations, disregarding their own limitations as well as the conflicts and complexity involved in the construction of value systems.     

How the New Web Generations are Changing Library and Information Services

The new Web generations are influencing the minds and changing the habits of software developers and end users. Users, librarians, and information services professionals can interact more efficiently, creating additional information and content and generating knowledge. This new scenario is also changing the behavior of information providers and users in health sciences libraries. This article reviews the new Web environments and tools that give librarians opportunities to tailor their services better, and gives some examples of the advantages and disadvantages for them and their users. Librarians need to adapt to the new mindset of users, linking new technologies, information, and people.     

Coherence estimate between a random and a periodic signal: Bias, variance, analytical critical values, and normalizing transforms

The present work deals with recent results on the sampling distribution of the magnitude-squared coherence (also called just coherence) estimate between a random (Gaussian) and a periodic signal, in order to obtain analytical critical values, alternative expressions for the probability density function (PDF) as well as the variance and bias of the estimate. A comparison with the more general case of coherence estimation when both signals are Gaussian was also provided. The results indicate that the smaller the true coherence (TC) values the closer both distributions become. The behaviour of variance and bias as a function of the number of data segments and the TC is similar for both coherence estimates. Additionally, the effect of a normalizing function (Fisher's z transform) in the coherence estimated between a random and a periodic signal was also evaluated and normality has been nearly achieved. However, the variance was less equalized in comparison with coherence estimate between two Gaussian signals.     

Relation between cognitive and motor performance in 5- to 6-year-old children: results from a large-scale cross-sectional study

The relation between cognitive and motor performance was studied in a sample of 378 children aged 5-6. Half of these children had no behavior problems; the others were selected for externalizing (38%) or internalizing problems (12%). Quantitative and qualitative aspects of motor performance were related to several aspects of cognition, after controlling for the influence of attention. No relation between global aspects of cognitive and motor performance was found. Specific positive relations were found between both aspects of motor performance, visual motor integration and working memory, and between quantitative aspects of motor performance and fluency. These findings reveal interesting parallels between normal cognitive and motor development in 5- to 6-year-old children that cannot be ascribed to attention processes.
