‘To go boldly’: teaching science fiction to first-year engineering students in a South African context

This paper reflects on the teaching of science fiction texts to first-year engineering students at the University of the Witwatersrand as part of a Critical Thinking course that uses literature as a vehicle through which to develop competence in critical literacy and communication. This course aims to equip engineering students, as future intermediaries between science and society, with the ability to fulfil this role in both the contemporary global world and South Africa more specifically through the imaginative inhabitation of divergent subject positions afforded by literary texts. Science fiction encourages students to engage imaginatively with various societal ideas, constructs and possibilities. One of the principles of the course is that reading facilitates empathic responses, challenging readers to inhabit unfamiliar subject positions. In this way, the teaching of science fiction aims to develop self-reflective and critical learning practices, wherein engineering students grapple with the ethical ramifications of extrapolated known science in a South African context.     

Analysis of a load application point in spline coupling teeth

The objective of this paper is to investigate the position of the resultant force in involute spline coupling teeth due to the contact pressure distribution for both ideal and misaligned conditions. In general, spline coupling teeth are in contact all along the involute profile and the load is far from uniform along the contact line. Theoretical models available in publications consider the resultant contact force as it is applied at the pitch diameter, and this study aims to evaluate the error introduced within the confines of a common approximation environment. This analysis is carried out through using finite element method （FEM） models, considering spline couplings in both ideal and misaligned conditions. Results show that the differences between the load application diameter and pitch diameter are not very obvious in both ideal and misaligned conditions; however, this ap- proximation becomes more important for the calculation of the tooth stiffness.     

Acute effects of two different tennis sessions on dorsal and lumbar spine of adult players

The aim of the study was to evaluate the dorsal and lumbar spine of expert and recreational tennis players before (pre) and after (post) two different training sessions. The sample consisted of 17 male tennis players, nine expert and eight recreational males (age 21.2 ± 1.6 years). We assessed the back surface by rasterstereography pre and post two different training sessions both lasting 1.5 h: a standard training and a specific over-shoulder shots training session, respectively. Lordotic and kyphotic angle, length, imbalance, inclination for trunk, pelvic torsion, left and right lateral deviation and surface rotation were measured. Tennis expertise (expert versus recreational) significantly affected the surface rotation and right lateral deviation (P < 0.05). Trunk length was affected by intervention (pre versus post) (P < 0.05). Left lateral deviation differed both for type of session (session 1 versus session 2) and intervention (P < 0.001, P < 0.05). Expert tennis players had higher values on surface rotation and right lateral deviation, around or just above physiological values (0–5° and 0–5 mm, respectively). Type of session significantly affected left lateral deviation, indicating that over-shoulder shots lead to a higher stress for the spine; the workload produced by both single sessions led to a shortening effect on trunk length. A single training session can induce acute modifications in some parameters of dorsal and lumbar spine of players.     

Evaluation policy in education: the effects of international standards and performativity on Brazil’s postgraduate programmes of excellence

The educational reforms that began in the 1990s have changed Brazilian universities’ direction from welfare state institutions to market organisations. In postgraduate education, strategic alliances with international agencies, governments and corporations have become closer. At the same time, there has been a push for internationalisation of knowledge and more efficiency – with quality assurance and accountability systems. This study, based on the theory of ‘policy enactments’ proposed by Stephen Ball and collaborators, aims to analyse the interpretation and translation of Brazil’s postgraduate education programmes’ evaluation policy. The data are derived from interviews with co-ordinators of four Brazilian postgraduate programmes in education – all regarded by the Higher Education Co-ordination Agency, CAPES, as programmes of excellence and of international standard (during the assessment triennials of 2004, 2007 and 2010). The data analysis provided a critical understanding of the evaluation policy as policy enactment, and of the small margin for manoeuvre in decision-making in response to the policy and performativity’s effect on academic subjectivity and collective practice.     

The influence of family socialisation on the success of girls from poor urban communities in Brazil at school

The principle focus of this article is to understand the influence of socialisation in the family on the success of girls at school. Eight low-income families with children of both sexes in the city of São Paulo, Brazil were studied through interviews and observation methods. It was found that socialisation in the family favoured in girls, and not in boys, the development of behaviours that schools desire, such as discipline. It also led each sex to attribute a different meaning to school attendance, since girls had more responsibilities and fewer opportunities for socialising. The same restrictions prompted girls to aspire to further their education and have higher skilled occupations.     

Taking Stock of Two Decades of Attachment Transmission Gap: Broadening the Assessment of Maternal Behavior

This report aimed to investigate the capacity of maternal behaviors tailored to children's attachment and exploration systems to jointly explain the well‐known mother–child transmission of attachment. Four home visits were conducted between ages 7 months and 2 years with 130 mother–child dyads to assess maternal attachment state of mind, sensitivity, autonomy support, and mother–child attachment security. Results showed that together, maternal sensitivity and autonomy support fully accounted for the relation between maternal and child attachment, that they each accounted for a unique portion of this relation, and that the magnitude of these mediated pathways was equivalent. These results suggest that the attachment transmission gap can be narrowed by the use of a theory‐driven multidimensional approach to maternal behavior.     

School educational project as a criterion of school choice: discourses and practices in the city of Barcelona

In its advancement towards an education quasi-market, Catalonia has recently been driving the development of school educational projects in all schools (both public and private) as a tool to facilitate school autonomy and family choices. A school educational project is a formal document in which schools identify their pedagogical goals, missions and orientations, their academic resources and organisational structures. Through the analysis of 60 in-depth interviews with parents of children at the age of commencing universal pre-primary education (three years old) and data collected from surveys completed by a representative sample made up of 3245 families, this article explores the impact of this policy on discourses and practices of school choice amongst families in the city of Barcelona. On the one hand, we observe that interest in educational projects has penetrated the discourses of the most educated parents, even though, at the same time, we detect a generalised lack of knowledge of the content of such projects. On the other hand, we note that the social composition of schools is still a prominent factor in choice practices. Such findings question the ideal of the autonomous and rational citizen-consumer that underlies the policy of establishing educational projects.
