The Ontogeny of Social Information Gathering

When facing the unknown, humans tend to consult others for guidance. This propensity to treat others as information sources has wide-ranging implications, being in part responsible for the breadth and depth of our world knowledge. As yet, little is known concerning when and how young children acquire this important skill. Social referencing and communicative abilities in infancy have been interpreted by many as reflecting precocious social information-seeking ability, but the evidence is far from compelling and equally compatible with an attachment regulation interpretation. While the evidence indicates that infants as young as 12 months are good consumers of social information, it falls well short of demonstrating that they are active seekers of that information. Moreover, genuine social information seeking requires an implicit conception of the knowledge-ignorance distinction, and existing research on children's theories of mind suggests that such a conception is most likely not available in infancy. For these reasons, we argue for a developmental account of social information-gathering ability, one that is consistent with the larger body of evidence concerning sociocognitive abilities in infants and young children.     

Education and sustainability: reinvigorating adult education’s role in transformation,justice and development

Distinctively economic objectives for lifelong education, especially adult learning and education, feature prominently in policy-making agendas and educators’ practice in much of the world. Critics contend that humanistic and holistic visions of lifelong learning for all have been marginalised and neglected. The current turn of political attention to issues of planetary environmental sustainability and to global societal transformation and interconnectedness raises further questions and prospects. Two United Nations’ publications in 2015: UNESCO’s Rethinking Education: toward a global common good? and of the United Nations’ Transforming our world: the 2030 Agenda for Sustainable Development pose intersecting concerns for lifelong learning and environmental sustainability. This article engages with those questions in particular regard to the role of adult learning and education. It discusses a field study of non-formal adult education in Ghana. The field study contributes evidence that resiliently humanistic conceptions and practices of non-formal adult education practically succeed to foster transformation, development and human flourishing. That effective humanism gives credence to the ambitiousness of UNESCO and UN agenda for transformation and sustainability and informs international debates.     

Supervision of Higher Degree Students — Problem Areas and Possible Solutions

Supervision of postgraduate students remains an area of concern to university administration, to supervisors, to student unions and the individual research student. Many studies have examined student dissatisfaction with supervision. However, there is also considerable uneasiness among academic staff about the extent of their supervisory role and functions. In a series of workshops in several tertiary institutions problem areas were discussed with supervisors, both experienced and inexperienced; and practices and strategies were explored which facilitate effective supervision. Those provisions for and approaches to supervision which supervisors have found to be effective are presented and discussed as they apply at the institutional, departmental or individual level.

Perspectives on the National Curriculum in Primary and Secondary Schools

Data on responses to the National Curriculum were gathered from personal interviews with a sample of 50 primary school head teachers, 304 primary class teachers and 223 secondary heads of department. In the primary schools concern centred around an anticipated increase in the level of assessment and record‐keeping and curriculum documentation. Increased levels of science and technology in the curriculum were also anticipated and these were the areas in which primary teachers felt in greatest need of support. In secondary schools changes were anticipated in individual subject curricula, especially in the fields of science and modem languages. The results suggest that there is great concentration in schools on a few specific areas of concern and that this may be at the expense of wider issues involved in the National Curriculum.     

Academic Values And Academic Practice In The New Universities

This paper reports some data of an ARC funded study of academic staff in a number of disciplines in colleges of advanced education and universities. Generally, more university than college academics scored high on academic motivation, on teaching‐research synergy and promotion of student independence, with college academics scoring higher on good teaching practice. There are disciplinary differences, too.

Slightly more than an average proportion of staff in the Social Sciences report good teaching practices. They are highly committed to promoting student independence, experience a fairly high level of teaching‐research synergy and have high intrinsic academic motivation. There is large‐scale consensus among Arts staff with university Arts academics scoring highest on promoting student independence, academic motivation, and teaching‐research synergy, and academics in CAE Arts departments scoring highest of all on good teaching practices.

Science staff seem to have different academic values and practices. Their academic motivation is about “average”, and fewer science academics report good teaching practices or practices that promote student independence. In their own work they also experience less teaching‐research synergy. Engineering staff show the lowest academic motivation, least commitment to student independence, experience least teaching‐research synergy, and report below average good teaching practices.

Health Science staff are akin to staff in Arts and Social Sciences in areas concerned with students, e.g. good teaching practices and promotion of student independence. In the areas which tap into their values as academics, e.g. academic motivation and teaching‐research synergy, they seem to be more like science and engineering staff.

Commerce/Law staff were on all aspects somewhere in the middle.     

Intensity of exercise recovery, blood lactate disappearance, and subsequent swimming performance

The aim of this study was to examine the effects of active versus passive recovery on blood lactate disappearance and subsequent maximal performance in competitive swimmers. Fourteen male swimmers from the University of Virginia swim team (mean age 20.3 years, s= 4.1; stature 1.85 m, s= 2.2; body mass 81.1 kg, s= 5.6) completed a lactate profiling session during which the speed at the lactate threshold (V(LT)), the speed at 50% of the lactate threshold (V(LT.5)), and the speed at 150% of the lactate threshold (V(LT1.5)) were determined. Participants also completed four randomly assigned experimental sessions that consisted of a 200-yard maximal-effort swim followed by 10 min of recovery (passive, V(LT.5), V(LT), V(LT1.5)) and a subsequent 200-yard maximal effort swim. All active recovery sessions resulted in greater lactate disappearance than passive recovery (P < 0.0001 for all comparisons), with the greatest lactate disappearance associated with recovery at V(LT) (P= 0.006 and 0.007 vs. V(LT.5) and V(LT1.5) respectively) [blood lactate disappearance was 2.1 mmol l(-1) (s= 2.0), 6.0 mmol l(-1) (s=2.6), 8.5 mmol l(-1) (s= 1.8), and 6.1 mmol l(-1) (s= 2.5) for passive, V(LT.5), V(LT), and V(LT1.5) respectively]. Active recovery at VLT and V(LT1.5) resulted in faster performance on time trial 2 than passive recovery (P=0.005 and 0.03 respectively); however, only active recovery at V(LT) resulted in improved performance on time trial 2 (TT2) relative to time trial 1 (TT1) [TT2- TT1: passive +1.32 s (s= 0.64), V(LT.5) +1.01 s (s= 0.53), V(LT) -1.67 s (s= 0.26), V(LT1.5) -0.07 s (s = 0.51); P < 0.0001 for V(LT)). In conclusion, active recovery at the speed associated with the lactate threshold resulted in the greatest lactate disappearance and in improved subsequent performance in all 14 swimmers. Our results suggest that coaches should consider incorporating recovery at the speed at the lactate threshold during competition and perhaps during hard training sessions.     

Quantifying Error and Uncertainty Reductions in Scaling Functions: An ITEMS Module

This module describes and extends X‐to‐Y regression measures that have been proposed for use in the assessment of X‐to‐Y scaling and equating results. Measures are developed that are similar to those based on prediction error in regression analyses but that are directly suited to interests in scaling and equating evaluations. The regression and scaling function measures are compared in terms of their uncertainty reductions, error variances, and the contribution of true score and measurement error variances to the total error variances. The measures are also demonstrated as applied to an assessment of scaling results for a math test and a reading test. The results of these analyses illustrate the similarity of the regression and scaling measures for scaling situations when the tests have a correlation of at least .80, and also show the extent to which the measures can be adequate summaries of nonlinear regression and nonlinear scaling functions, and of heteroskedastic errors. After reading this module, readers will have a comprehensive understanding of the purposes, uses, and differences of regression and scaling functions.
