Citizenship education in England 2001-2010 : young people's practices and prospects for the future : the eighth and final report from the Citizenship Education Longitudinal Study (CELS)

On the one hand, there has been a marked and steady increase in young people’s civic and political participation and indications that these young people will continue to participate as adult citizens. In contrast, there has been a hardening of attitudes toward equality and society, a weakening of attachment to communities and fluctuating levels of engagement, efficacy and trust in the political arena. The factors that shape young people’s citizenship outcomes include age and life-stage, background factors, prior citizenship outcomes, as well as levels of ‘received’ citizenship education

Barriers to participation in education and training

This study explores the barriers and constraints young people currently face when deciding what to do at the end of their compulsory schooling in Year 11. The study conducted by the NFER, working in partnership with Triangle and QA Research, included a survey of 2029 young people who completed Year 11 in either 2008 or 2009 conducted between August and October 2009. This survey was supplemented by interviews with booster samples of 519 young people across specific sub-groups and 102 parent interviews

Harnessing Technology Schools Survey 2009: analysis report

The Harnessing Technology schools survey (HTSS) report presents the key survey findings from the academic year 2008-09 set out according to the five system outcomes against which impact of the strategy was measured. The HTSS was an annual national survey of ICT in primary, secondary and special schools. (The data report that accompanied this analysis provides further details of the sample and the characteristics of respondents and is listed separately.

This document, the data report, is a reference document which presents the data in tabular form for anyone who wants to examine the findings of the Harnessing Technology Schools Survey (HTSS) in depth, for example in relation to specific areas of technology or policy, or by school sector. The findings for each question are also set out by school sector by primary, secondary and special school sub-samples

Characterization of Puberty in an Australian Population-Based Cohort Study

Purpose: Current knowledge of the characteristics of puberty beyond age at menarche and thelarche is limited, particularly within population-based cohorts. Secular trends and concerns of the health effects of early puberty reinforce the value of contemporary studies characterizing the timing, tempo, duration, and synchronicity of puberty. // Methods: The Childhood to Adolescence Transition Study is a unique Australian cohort of individuals followed annually from late childhood to late adolescence, with up to eight assessments of pubertal stage from 9 to 19 years of age (N = 1,183; 636 females). At each assessment, females reported their Tanner Stage of breast and pubic hair development, while males reported on genital/pubic hair development. Nonlinear mixed-effects models characterized pubertal trajectories and were used to derive each individual’s estimates of timing, tempo, and synchronicity. Parametric survival models were used to estimate the overall duration of puberty. // Results: Timing of mid-puberty (Tanner Stage 3) ranged from 12.5 to 13.5 years, with females developing approximately 6 months before males. Pubertal tempo (at mid-puberty) was similar across sex (between half and one Tanner Stage per year), but the overall duration of puberty was slightly shorter in males. Most females exhibited asynchronous changes of breast and pubic hair development. // Discussion: Estimates of pubertal timing and tempo are consistent with reports of cohorts from two or more decades ago, suggesting stabilization of certain pubertal characteristics in predominantly White populations. However, our understanding of the duration of puberty and individual differences in pubertal characteristics (e.g., synchronicity of physical changes) remains limited

Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies

Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining the mechanism that counter-intuitively heats coronae to temperatures that are orders of magnitude hotter than the corresponding photospheres. It is widely accepted that the magnetic field is responsible for the heating, but there are two competing mechanisms that could explain it: nanoflares or Alfv\'en waves. To date, neither can be directly observed. Nanoflares are, by definition, extremely small, but their aggregate energy release could represent a substantial heating mechanism, presuming they are sufficiently abundant. One way to test this presumption is via the flare frequency distribution, which describes how often flares of various energies occur. If the slope of the power law fitting the flare frequency distribution is above a critical threshold, $\alpha=2$ as established in prior literature, then there should be a sufficient abundance of nanoflares to explain coronal heating. We performed $>$600 case studies of solar flares, made possible by an unprecedented number of data analysts via three semesters of an undergraduate physics laboratory course. This allowed us to include two crucial, but nontrivial, analysis methods: pre-flare baseline subtraction and computation of the flare energy, which requires determining flare start and stop times. We aggregated the results of these analyses into a statistical study to determine that $\alpha = 1.63 \pm 0.03$. This is below the critical threshold, suggesting that Alfv\'en waves are an important driver of coronal heating.Comment: 1,002 authors, 14 pages, 4 figures, 3 tables, published by The Astrophysical Journal on 2023-05-09, volume 948, page 7
