Human Anatomy: Teaching–Learning Experience of a Support Teacher and a Student with Low Vision and Blindness

In Brazil, a federal law ensures that all students with disabilities are entitled to enrollment in higher education institutions. Higher courses in human anatomy stand out for their complexity in both theoretical and practical contents. Therefore, adaptation is required to accommodate students with special educational needs. This study aimed to describe the experience of a Support Teacher in the development of inclusive pedagogical practices for the discipline of Human Anatomy offered in the physiotherapy course for a student with low vision and blindness. The challenges and learning difficulties faced by a visually impaired student are reported. Qualitative analysis was performed by interviewing a student with low vision and blindness and a Support Teacher. The audio recordings were transcribed, categorized, and analyzed using content analysis. The Support Teacher created schematics and drawings of anatomical structures, reviewed theoretical and practical contents, developed adaptations of the examinations, and applied palpatory anatomy to facilitate the student’s learning process. The findings illustrate that the student faced the greatest difficulty in dealing with the emotional aspects, due to the inability to visualize the anatomical details in human cadavers. Thus, the presence of a Support Teacher was fundamental to ensure that the student could learn the content and overcome this limitation. In conclusion, personalized adaptation, commitment, and collaborative work between the Support Teacher and students with low vision and blindness improve their learning conditions.     

Students’ and teachers’ perspectives about quality of engineering education in Portugal

Quality in higher education is a subject of increasing importance. This idea can be supported by looking at different sources, namely, the scientific literature, national and transnational governments’ policies, such as those emerging from the Bologna Process. Also, the internationalisation of higher education and, within it, students’ and staff mobility among institutions, has brought to the agenda the quality issue, particularly with regard to the teaching and learning process. Several authors argue that the meaning of quality depends on who defines it. This article focuses on a study that looks at how teachers and students in higher education institutions, in Portugal and in the domain of Engineering, see the quality issue. Data was collected through interviews to teachers (six) and students (38) in two different Portuguese institutions. The results indicate that, although teachers and students refer to the same dimensions that influence quality, they have different perspectives about their importance. From the point of view of the authors, this discrepancy requires some pedagogical actions in the context where the study was developed and, also, further research to see if the same tendency exists in different settings.     

Three-feature model to reproduce the topology of citation networks and the effects from authors’ visibility on their h-index

Various factors are believed to govern the selection of references in citation networks, but a precise, quantitative determination of their importance has remained elusive. In this paper, we show that three factors can account for the referencing pattern of citation networks for two topics, namely “graphenes” and “complex networks”, thus allowing one to reproduce the topological features of the networks built with papers being the nodes and the edges established by citations. The most relevant factor was content similarity, while the other two – in-degree (i.e. citation counts) and age of publication – had varying importance depending on the topic studied. This dependence indicates that additional factors could play a role. Indeed, by intuition one should expect the reputation (or visibility) of authors and/or institutions to affect the referencing pattern, and this is only indirectly considered via the in-degree that should correlate with such reputation. Because information on reputation is not readily available, we simulated its effect on artificial citation networks considering two communities with distinct fitness (visibility) parameters. One community was assumed to have twice the fitness value of the other, which amounts to a double probability for a paper being cited. While the h-index for authors in the community with larger fitness evolved with time with slightly higher values than for the control network (no fitness considered), a drastic effect was noted for the community with smaller fitness.     

Lie Acceptability: A Construct and Measure

People likely hold different opinions about deceptive communication. Lie acceptability refers to an individual's attitude about deceptive communication. A self-report measure of lie acceptability was updated and refined, and preliminary data (N = 312) consistent with validity were reported. CFA indicated acceptable fit to the a priori unidimensional model. As anticipated, the lie acceptability scale was positively related to narcissism and negatively associated with religiosity. The scale also predicted likelihood of use ratings of equivocal messages, deceptive omissions, and outright lies. An anticipated sex difference, however, was not replicated. The potential utility of the scale in communication research is discussed.     

On the Commodification of Science: The Programmatic Dimension

The article is a partial result of a wider research project, in which the commodification of science is interpreted, from one point of view, as a facet of the rise of neoliberalism, and from another, as a set of processes, classified according to a three-category taxonomy. Only one of the taxonomy’s categories is dealt with in this article, the one that concerns the processes that affect the programme of scientific research. First a sketch is presented of the historical background and the periodization of the most relevant epoch for the study of the commodification of science, namely, the one from the end of World War II to the present. The periodization is expressed in the notions of Golden Years science and neoliberal science. The ensuing sections have the aims: to show that, in Golden Years science, the processes shaping research programmes did not include commodification; to characterize the period of transition of the 70 s; to describe the processes of commodification that have impact on the research programmes of neoliberal science; to discuss criticisms that have been levelled against them, as well as proposals for better ways of conducting scientific practices, and their implications for science education (which are of the same nature as that of Science & Education’s editorial line); and finally, to bring to light the differences between developed and emerging countries as far as the commodification of science is concerned.     

Deafness and attention in deaf children

The study shows the differences between hearing parents and deaf instructors interacting with deaf children and directing their attention. Data were collected at home and at a service for special needs in Bristol, England. The mother or instructor was asked to play naturally with the child with the toys provided. When the child's attention was focused during their play, the mother or instructor had to try to direct the child's attention to each of the toys. The results suggest that both groups (mothers and instructors) were effective in directing attention to objects not in the immediate area of play; however, hearing mothers were more successful than deaf instructors.     

Developing Elementary Teachers’ Understandings of Hedges and Personal Pronouns in Inquiry-Based Science Classroom Discourse

This study examined the effectiveness of introducing elementary teachers to the scholarly literature on personal pronouns and hedges in classroom discourse, a professional development strategy adopted during a summer institute to enhance teachers’ social understanding (i.e., their understanding of the social functions of language in science discussions). Teachers became aware of how hedges can be employed to remain neutral toward students’ oral contributions to classroom discussions, invite students to share their opinions and articulate their own ideas, and motivate students to inquire. Teachers recognized that the combined use of I and you can render their feedback authoritative, you can shift the focus from the investigation to students’ competence, and we can lead to authority loss. It is argued that explicitness, reflectivity, and contextualization are essential features of professional development programs aimed at improving teachers’ understandings of the social dimension of inquiry-based science classrooms and preparing teachers to engage in inquiry-based teacher–student interactions.     

A Counselling Experiment in Brazil: Difficulties and Opportunities

This paper compares the No Blame approach to bullying with the ecosystemic approach to changing problem behaviour. It suggests that there are several similarities between the two approaches: they are both applicable in particular kinds of situation; their success depends to a great extent on the people using the technique, in particular the degree to which they can bring the quality of genuineness to the situation; they are not directly concerned with punishment, truth or control; and they challenge the assumptions teachers make about children's problem behaviour. A key point is the need for teachers to recognize that bullying is a natural event (in so far that it is a regular one) and the need to suspend their own feelings of anger and repugnance. As the writer points out, ‘a process which fails to engage the bully and makes no attempt to enhance feelings of concern and understanding is unlikely to bring about any fundamental change in behaviour’. Though written at a fairly theoretical level, what the writer says has direct relevance to practice in schools.     

Output-feedback binary adaptive control of MIMO systems using monitoring function

The problem of adaptive control design for multivariable linear time-invariant plants with unknown control direction is considered. A solution is proposed based on the SDU factorization of the high frequency gain matrix (HFG) and the monitoring function approach. The adaptation scheme is the binary model reference adaptive control (BMRAC) which utilizes parameter projection and sufficiently high adaptation gains. The signs of the leading principal minors of the HFG define the control directions, and the lack of knowledge of which is a major challenge in the multivariable framework. The role of the monitoring function is to monitor the output error transient and then provide the necessary changes of the adaptation gain signs to guarantee a stable adaptive control. In addition to proving the signal boundedness of the resulting closed-loop system, the output tracking error is shown to be asymptotically as well as exponentially practically stable, i.e., exponentially stable with respect to a small residual compact set of size inversely proportional to the BMRAC adaptation gain. The latter implies good transient properties of the output tracking error in contrast to conventional adaptive laws which only guarantee asymptotic stability but can lead to extremely slow error convergence. The extension of the proposed approach to matched disturbances is also briefly discussed following the classical paradigm of disturbance estimators. Numerical results with a visual servoing application illustrate the efficiency of the proposed method.     

Leg preference and interlateral asymmetry of balance stability in soccer players

To examine the effect of long lasting practice on pedal behavior in sport, we compared experienced adult soccer players and nonsoccer players on leg preference in motor tasks requiring general mobilization, soccer related mobilization, and body balance stabilization. We also evaluated performance asymmetry between the right and left legs in static and dynamic unipedal body balance, based on center of pressure displacement, and correlated that with leg preference in balance stabilization tasks. Results revealed (a) a distinct leg preference between mobilization and stabilization tasks, which were significantly different between players and nonplayers, (b) similar balance stability between the right and left legs, (c) greater stability of experienced players compared with nonplayers in static and dynamic balance, and (d) absence of a significant leg preference correlation with interlateral balance asymmetry. These results suggest an effect of extensive soccer skill practice on establishing leg preference for specific mobilization tasks and overall balance control.
