Positioning pedagogy—a matter of children’s rights

This paper foregrounds pedagogy in the realisation of children’s rights to non-discrimination and serving their best interests, as articulated in the UNCRC. Drawing on a mixed methodological study of teachers in 12 schools it does so through exploring teacher pedagogies in terms of how they 'think', 'do' and 'talk' pedagogy, conceived as their pedagogic 'habitus'. Findings confirm contradictions between teachers’ ideals and their practice that is significantly mediated by the socio-cultural context of their schools, gender and presence of migrant children. Especially striking is that neither social justice concerns nor children’s rights explicitly emerge in their narratives, in turn influencing how they ‘do’ pedagogy with different groups of children. This contradiction is understood as a dialectical process of re/action influenced by structures, policies and the exercise of power in local contexts. The UNCRC provides a generative mechanism within which to hold government to account for the impact of policies, especially in challenging contexts. To be realised in practice, however, it also needs to be embedded in teacher habitus, shaping their dispositions toward children’s rights to non-discrimination and serving their best interests in education.     

Differential response gradients to a Pavlovian safety signal following active avoidance training in young and adult rats

Following 300 training trials in two-way shuttle avoidance signaled by a tone (CS+), two groups each of weanling and adult rats were given Pavlovian discrimination training in which the CS+ was followed by inescapable shock, and a more intense tone (CS—) signaled no shock. An additional group at each age level received both tones paired randomly with shock or no shock. Subsequent generalization tests along the frequency dimension indicated that both pups and adults tested at the CS+ intensity showed similar gradients of frequency control. Gradients for the adults tested at the CS — intensity tended to be inverted, with least responding at CS—, a result not found in the young subjects. The results were considered in light of Pavlovian extradimensional influences on the control of avoidance behavior.     

The Roles of Maternal Psychopathic Traits,Maternal Antisocial Personality Traits,and Parenting in the Development of Child Psychopathic Traits

Objective. The development of psychopathic traits in children has been largely understudied compared with the etiology of these traits in adults; therefore, this study aims to elucidate factors that may be involved in the development of psychopathic traits in childhood. Design. The potential impact of maternal personality traits on parenting practices and child personality were examined. Specifically, statistical relations were examined among maternal psychopathic traits, maternal antisocial personality traits, and child psychopathic traits, and the role of parenting as a potential mediator and/or moderator of these relations within an all-male sample (N = 75) between the ages of 7 and 11 years. Results. Parenting mediated the relation between maternal antisocial personality traits and child psychopathic traits, but not the relation between maternal and child psychopathic traits. In addition, positive parenting interacted statistically with maternal psychopathic traits, such that maternal and child psychopathic traits were related only when positive parenting practices were lacking. Conclusion. These findings support the consideration of parenting as a point of intervention in the prevention of childhood psychopathic traits.     

An Investigation of Classification Consistency Indexes Estimated Under Alternative Strong True Score Models

Using several data sets, the authors examine the relative performance of the beta binomial model and two other more general strong true score models in estimating several indexes of classification consistency. It is shown that the beta binomial model can provide inadequate fits to raw score distributions compared to more general models. This lack of fit is reflected in differences in decision consistency indexes computed using the beta binomial model and the other models. It is recommended that the adequacy of a model in fitting the data be assessed before the model is used to estimate decision consistency indexes. When the beta binomial model does not fit the data, the more general models discussed here may provide an adequate fit and, in such cases, would be more appropriate for computing decision consistency indexes.     

Structural Zeros and Their Implications With Log‐Linear Bivariate Presmoothing Under the Internal‐Anchor Design

In equating, when common items are internal and scoring is conducted in terms of the number of correct items, some pairs of total scores (X) and common‐item scores (V) can never be observed in a bivariate distribution of X and V; these pairs are called structural zeros. This simulation study examines how equating results compare for different approaches to handling structural zeros. The study considers four approaches: the no‐smoothing, unique‐common, total‐common, and adjusted total‐common approaches. This study led to four main findings: (1) the total‐common approach generally had the worst results; (2) for relatively small effect sizes, the unique‐common approach generally had the smallest overall error; (3) for relatively large effect sizes, the adjusted total‐common approach generally had the smallest overall error; and, (4) if sole interest focuses on reducing bias only, the adjusted total‐common approach was generally preferable. These results suggest that, when common items are internal and log‐linear bivariate presmoothing is performed, structural zeros should be maintained, even if there is some loss in the moment preservation property.     

Selling Translation Rights

Advancing technologies and new political landscapes have made the process of buying and selling translation rights more complicated. The translation contract is a complex document that varies from proprietor to proprietor. The article features a chart that is intended to serve as a framework for understanding the typical contract a publisher will be asked to sign when purchasing translation rights from an American proprietor.     

Acute neuromuscular and performance responses to Nordic hamstring exercises completed before or after football training

ABSTRACT

The optimal scheduling of Nordic Hamstring exercises (NHEs) relative to football training sessions is unknown. We examined the acute neuromuscular and performance responses to NHE undertaken either before (BT) or after (AT) simulated football training. Twelve amateur players performed six sets of five repetitions of the NHE either before or after 60 min of standardised football-specific exercise (SAFT⁶⁰). Surface electromyography signals (EMG) of the hamstring muscles were recorded during both the NHE, and maximum eccentric actions of the knee flexors (0.52 rad · s^–1) performed before and after the NHE programme, and at 15 min intervals during SAFT⁶⁰. Ten-metre sprint times were recorded on three occasions during each 15 min SAFT⁶⁰ segment. Greater eccentric hamstring fatigue following the NHE programme was observed in BT versus AT (19.8 %; very likely small effect), which was particularly apparent in the latter range of knee flexion (0–15°; 39.6%; likely moderate effect), and synonymous with hamstring EMG declines (likely small–likely moderate effects). Performing NHE BT attenuated sprint performance declines (2.0–3.2%; likely small effects), but decreased eccentric hamstring peak torque (–14.1 to –18.9%; likely small effects) during football-specific exercise. Performing NHE prior to football training reduces eccentric hamstring strength and may exacerbate hamstring injury risk.
