Patterns of Early‐Life Social and Environmental Exposures and Child Cognitive Development,Rhea Birth Cohort,Crete, Greece

Early‐life exposures are critical for later child cognitive development. McCarthy Scales of Children's Abilities (MSCA) were used to assess cognitive development of 700 preschoolers (M_age = 4.2 years), derived from the “Rhea” birth cohort, in Greece. Principal component analysis (PCA) was applied on prospectively collected exposure data. Six components were extracted; five of them were associated with child cognition. Higher parental social status, preschool attendance and less TV watching, nonsmoking during pregnancy and breastfeeding, and parental involvement in child life were protective factors of child cognition at 4 years. Increased child birth order was negatively associated with child cognition. Offspring's size at birth was not associated with any cognitive outcome. These findings reveal the importance of early‐life exposures to child cognitive development.     

Group size and organisational conditions for children’s learning in preschool: a teacher perspective

Background:?There is a limited amount of research about group size in preschool, and how it impacts on teachers’ working conditions and their ability to support children’s learning and knowledge development in line with curriculum intentions.

Purpose:?From a perspective on quality, this article examines the organisational conditions for children’s learning in preschool in relation to group size. The questions at issue are: how do teachers explain how they organise the child group and the learning environment in preschool, and why?

Sample:?The sample consists of 12 preschools from different parts of Sweden. The preschools selected for the study are stratified in order to represent small and large group sizes in Swedish preschools as defined by the Swedish National Agency for Education. The sample contains both urban and rural regions and represents districts that differ geographically, demographically, ethnically, and which include varied socioeconomic structures. The 12 preschools had children in three age groupings: 1–3, 3–5 or 1–5. The number of children in the participating preschools ranged from 12 children to 45 children, with seven of the preschools having more than 30 children in their groups.

Design and method:?The article is based on interactionist perspectives, Bronfenbrenner’s ecological systems theory, a critical ecology of the early childhood profession, theories of children’s learning, and four dimensions of pedagogical quality. Together, these theoretical perspectives contribute to an understanding of the relationships between policy issues, educational goals, group size and teachers’ competence in organising and creating conditions for children’s learning. Semi-structured interviews were conducted with two teachers from each of the 12 preschools. The interviews lasted between 40–60 minutes and were recorded and transcribed verbatim. The analytical process was conducted in three steps and can be described as an analytical process of abduction. The four dimensions of pedagogical quality were used as analytical lenses to discern and understand critical aspects related to the teachers’ understanding of group size.

Result: Irrespective of group size, most of the children participate in different group constellations throughout the day, some organised by the teachers and some by the children themselves. Teachers’ competence to organise the children in such ways that good conditions for learning were created, differed between preschools, and depended on the teachers’ approach, which can be described as either intentional or unintentional learning.

Conclusion: Teachers’ organisational approaches influence the quality of the preschool and conditions for children’s learning in distinct ways.     

The Intersection Between Deep Moral Frames and Rhetorical Style in the Struggle over U.S. Immigration Reform

This essay highlights and explores a point of tension between theoretical writings on style and moral frames. Past political communication scholarship points to the importance of the feminine style in today's televisual era of politics. In this same political era, the conservative strict parent moral frame has dominated most policy debates. Surprisingly, this highly successful moral frame appears squarely at odds with the feminine style so closely connected with political success. This essay attempts to unravel this tension between styles and frames by examining discourse drawn from the 2007 debate over comprehensive immigration reform. To account for the success of conservative messages within this debate, this essay both (a) calls into question the nature of the relationship between the television medium and the feminine style and (b) expands our understanding of the discursive operation of deep moral frames by drawing a distinction between intra-familial and extra-familial policy discourse.     

A philosophical perspective on leading music activities for the over 50s

The basis of this article is findings from the Music for Life Project which investigated the benefits and challenges of music activity participation for the over 50s in three case study sites in the United Kingdom. The paper uses a philosophical lens to explore the leaders’ and participants’ views on the purpose of the activities, how learners are characterised, the role of the activity leader, and the use of assessment. Data from 147 participant and 13 activity leader questionnaires, from 28 participant and 13 activity leader individual interviews, and from 15 participant focus groups were analysed within a philosophical framework that refers to six approaches: liberal, progressive, behaviourist, humanistic, radical and analytic. NVivo and SPSS assisted with the quantitative and qualitative analyses. The analyses indicated that humanism was prevalent although other approaches, particularly behaviourist and progressive, were evident. Activity leaders’ emphasis on humanism might lead to more concern with the comfort side of participation than with musical progression. There was very little use of formal assessment or feedback to support progression. There was some discrepancy between purposes for participation between leaders and participants. There might be a need to clarify purpose, particularly if activities are part of adult education rather than adult social groups.     

Perceived Rates of Return to Higher Education: an international review and comparison

The present paper attempts to assess the link between economic factors and the private demand for higher education through an investigation of the findings of relevant studies. After an examination of the various methodologies adopted by different authors in the estimation of the perceived rate of return to higher education, the main findings of available studies conducted in several countries (UK, the Philippines, Egypt, Hong Kong, and Cyprus) are discussed and compared. The main conclusions drawn from this comparison are the following: First, the perceived rates of return to higher education are, for the most part, very realistic, indicating an accurate perception of the economic benefits of higher education on the part of students. Second, non‐economic factors, such as gender, ability and socio‐economic background, appear to constitute strong influences on the private demand for higher education, which educational policy makers should take into account, along with the economic variables. Finally, it is suggested that the methodology discussed in the present paper can be used in the future to estimate the perceived profitability of higher studies at different institutions and countries offering higher education.     

Engaging with holistic curriculum outcomes: deconstructing ‘working theories’

International debates persist about what constitutes desirable outcomes from early childhood education experiences. The New Zealand early childhood curriculum brings together academic and social-pedagogic outcomes as interdependent holistic constructs named ‘dispositions’ and ‘working theories’. These constructs are complex notions that require interpretation by researchers and teachers in order to be recognised as outcomes by those with a vested interest in children's education: parents and policy-makers. This paper engages with the construct of working theories. It explains its genesis and outlines research activity thus far. The paper draws on findings from a two-year qualitative research project exploring children's interests, inquiries and working theories. The paper analyses two vignettes of working theories into mutually constitutive components of knowledge, skills and strategies, and attitudes and expectations. It argues that deconstructing working theories into elements able to be recognised by those outside early childhood education provides a way to demystify these innovative outcomes. Such scrutiny may assist parents and policy-makers to understand ways that the learning they value is present in the early years. Further, holistic outcomes are responsive to research and scholarship on appropriate pedagogy that encourages children to develop identities as learners, identities critical to living in the twenty-first century.     

Isolation and enrichment of low abundant particles with insulator-based dielectrophoresis

Isolation and enrichment of low-abundant particles are essential steps in many bio-analytical and clinical applications. In this work, the capability of an insulator-based dielectrophoresis (iDEP) device for the detection and stable capture of low abundant polystyrene particles and yeast cells was evaluated. Binary and tertiary mixtures of particles and cells were tested, where the low-abundant particles had concentration ratios on the order of 1:10 000 000 compared to the other particles present in the mixture. The results demonstrated successful and stable capture and enrichment of rare particles and cells (trapping efficiencies over 99%), where particles remained trapped in a stable manner for up to 4 min. A device with four reservoirs was employed for the separation and enrichment of rare particles, where the particles of interest were first selectively concentrated and then effectively directed to a side port for future collection and analysis. The present study demonstrates that simple iDEP devices have appropriate screening capacity and can be used for handling samples containing rare particles; achieving both enrichment and isolation of low-abundant particles and cells.
