Networks in Education: An Analysis of Selected Discourses

‘Network’ is a fashionable and current term in every field of contemporary society and education is no exception. In this paper, the concept of network (and other associated concepts, such as partnership and collaboration) is reviewed. Such revision regards selected theoretical contributions and is explored in terms of the use of the concepts in legal documents and in the discourses of aldermen and educational officers from Portuguese municipalities, offering a critical and multi-layered perspective. The analysis reveals the various layers of the network concept, often appearing vague and diffuse. It is a floating signifier disputed by different discourses and embodied by different meanings. This, in turn, brings major research problems linked to the use of the concept of network in education.     

Effects of the use of raised line drawings on blind people’s cognition

The creation of inclusive schools is no simple process as it implies huge changes that might generate resistance and fears, which can undermine the process of change. Quite often the changes in the legislation do not correspond to changes in the conceptions and/or practices of the actors involved in the process. As such, it is important to study what is happening in schools and to understand how they are managing to implement the political changes and overcome the tensions and difficulties they face. This is a comparative case study, aimed at describing five mainstream school teachers, their beliefs and practices, and how these are related to other schooling conditions. This study raises some questions, namely about the importance of an adequate regular school teacher support and an adequate education.     

How individualised are the Individualised Education Programmes (IEPs): an analysis of the contents and quality of the IEPs goals

The Individualised Education Programme (IEP) is a fundamental document that describes all educational responses to the additional support needs of students, setting up the guideline for their learning and developmental experiences. Specifically, the IEP goals represent the personal destination translated into desirable behaviours and skills that will enable students with additional support needs to meet their educational and functional needs. This paper analysis the quality of the 2497 IEP goals established for 135 Portuguese students with additional support needs and their fit to the students’ level of severity and educational level. The quality of IEP goals was measured using the Revised IFSP/IEP Goals and Objectives Rating Instrument and the content was categorised in reference to the International Classification of Functioning, Disability and Health, version for Children and Youth. Findings showed that goals are generally poorly written, particularly in terms of their measurability and that their quality decreases as students’ progress in education. Results also showed that IEP goals for students with a highly individualised curriculum do not attend to their needs of more functional contents. The results are discussed in terms of their implications for teacher training.     

La Ola Latina: Recent Scholarship in Latina/o and Latin American Rhetorics

For generations, critics have dismissed James Forman's “Black Manifesto” as a rhetorical failure. Such judgments tend to focus on the prophetic and retributive registers of the speech and fail to account for the full range of its ironic structuration. By examining the complex interchange of prophetic, retributive, and tragic registers through which the “Manifesto” is constructed, we can more fully appreciate how Forman created a space for his auditors to reflect and redirect the vengeful and violent sociohistorical drama seemingly otherwise implied. At the same time, it helps to explain why some black auditors embraced the leadership role Forman directed them to assume, while many whites reviled the supporting role to which they were consigned. Interpreting the speech in terms of the interplay of its multiple ironic registers invites us to focus attention on the ways in which ironic protest rhetoric operates in dialogue, holding both the ironist and the audience accountable for the productivity of their encounter.     

Benefits of achieving vigorous as well as moderate physical activity recommendations: Evidence from heart rate complexity and cardiac vagal modulation

Abstract

The aim of this study was to examine differences in traditional heart rate variability measurements and heart rate complexity (sample entropy) in young adults grouped by objectively measured achievement of either moderate or both moderate and vigorous physical activity recommendations. Of 168 young adults tested (86 females, 82 males; age 20.5 ± 1.2 years), 119 achieved only recommendations for moderate physical activity (moderate group) and 49 achieved recommendations for both moderate and vigorous physical activity (vigorous group). Analysis of covariance controlling for sex, weekly minutes of moderate physical activity, and percentage of body fat was used to assess between-group differences in heart rate variability and heart rate complexity. Logistic regression analysis was used to determine the group characteristics that best predicted high heart rate complexity and vagal indices of heart rate variability. The majority of the autonomic measures were higher (P < 0.05) in the vigorous group, and regression analysis showed that vigorous physical activity was the only multivariate predictor of higher heart rate complexity and higher heart rate variability. Young adults engaged in regular vigorous physical activity were more than twice as likely to have high heart rate complexity than those involved in predominantly moderate exercise. These findings suggest that vigorous physical activity is more closely associated with high heart rate complexity than moderate physical activity in young adults.

Isokinetic hamstrings-to-quadriceps peak torque ratio: the influence of sport modality, gender, and angular velocity

The purpose of this study was to determine differences in hamstrings-to-quadriceps (H/Q) peak torque ratios evaluated at different angular velocities between men and women who participate in judo, handball or soccer. A total of 166 athletes, including 58 judokas (26 females and 32 males), 39 handball players (22 females and 17 males), and 69 soccer players (17 females and 52 males), were evaluated using an isokinetic dynamometer. The H/Q isokinetic peak torque ratios were calculated at angular velocities of 1.05 rad · s?1 and 5.23 rad · s?1. In the analysis by gender, female soccer players produced lower H/Q peak torque ratios at 1.05 rad · s?1 than males involved in the same sport. However, when H/Q peak torque ratio was assessed at 5.23 rad · s?1, there were no significant differences between the sexes. In the analysis by sport, there were no differences among females at 1.05 rad · s?1. In contrast, male soccer players had significantly higher H/Q peak torque ratios than judokas (66 ± 12% vs. 57 ± 14%, respectively). Female handball players produced significantly lower peak torque ratios at 5.23 rad · s?1 than judokas or soccer players, whereas males presented no ratio differences among sports At 5.23 rad · s?1. In the analysis by velocity, women's muscular ratios assessed at 1.05 rad · s?1 were significantly lower than at 5.23 rad · s?1 for all sports; among men, only judokas presented lower ratios at 1.05 rad · s?1 than at 5.23 rad · s?1. The present results suggest that sport modality and angular velocity influence the isokinetic strength profiles of men and women.     

3D preserving xviii century barroque masterpiece: Challenges and results on the digital preservation of Aleijadinho's sculpture of the Prophet Joel

We present our recent efforts in the digital preservation of a set of baroque sculptures made by Antônio Francisco Lisboa, known as O. Aleijadinho, which is an important American baroque artist. The set was made in the beginning of the xix century and is composed of 12 near real sized sculptures, hand-carved in soapstone. These sculptures represent 12 of the 16 prophets from the Holy Bible and are part of a UNESCO World Heritage Site. Our group has been collaborating with UNESCO in a project that aims to preserve all these statues. We hereby present our initial efforts, consisting of the 3D digital preservation of the Prophet Joel sculpture. We developed a complete 3D digital preservation pipeline composed of four main stages: data acquisition, 3D reconstruction, texture generation and 3D model visualization. By evaluating our results in this first sculpture, we discuss the improvements we conceived before applying our pipeline in the remaining ones. Finally, we present the 3D model of the Prophet which registers the sculpture's current state and will be used in restoration, research and educational activities. We believe this contribution may be useful to guide further research on similar scenarios, showing how to avoid some practical mistakes and achieve good results.     

The Contribution of Ethnobiology to the Construction of a Dialogue Between Ways of Knowing: A Case Study in a Brazilian Public High School

This paper reports results obtained in pedagogical interventions in a Brazilian public high school which aimed at promoting a dialogue between scientific and traditional knowledge in the context of biology teaching. The interventions were based on the use of a didactic material and teaching sequence elaborated on the grounds of school knowledge about botany, as presented in biology textbooks, and interviews with students who were also farmers, so as to gather data about their ethnobiological knowledge. Our goal was to develop and test resources that can offer support for teachers who wish to build a dialogue between different ways of knowing in multicultural settings. Our results indicate that the use of the didactic material and teaching sequence indeed created possibilities for a dialogue between the students’ ethnobiological knowledge and biology school knowledge. We observed some shortcomings in classroom practice, partly reflecting our very choice of subject matter to develop the teaching sequence. But the interventions also revealed important limitations that we regard as representative of problems that may generally make multicultural science teaching a hard goal to achieve. It was clear that important shortcomings were related to teachers’ difficulties to conduct a dialogue between ways of knowing in a science classroom, and, thus, called attention to the importance of introducing a multicultural dimension into teacher education. We also observed that the fact that students did not show much sensitivity towards dealing with cultural diversity was a factor constraining the success of the interventions. These results highlight the importance of proposing and testing teacher education initiatives aiming at preparing them to teach science in a culturally sensitive manner, and also managing classroom tensions and conflicts so as to make it possible an effective dialogue between different ways of knowing in a multicultural setting.     

Scale of spectators’ motivations at soccer events

There are motivation sports events attending measuring tools, although so far these instruments have only been able to provide a limited explanation for attendance, which means that more sophisticated, useful scales are required. The aim of this research is to provide more efficient tool to measure the motivations of soccer events attendance. With this aim, a 14-item scale has been developed to measure the motivations that have been identified in a comprehensive review of specialized marketing literature. This scale, was used during a soccer event, showed a good global adjustment, internal consistency and validity, and found the following four dimensions explained 67% of variance in attendance: excitement, aesthetics, escape and connections to the team and its environment.
