Lifelong learning and lifelong education: a critique

It is suddenly fashionable in political circles in the United Kingdom (and elsewhere) to talk about lifelong learning and lifelong education. This seems to be the direct result of the present economic climate which has called into question many previous assumptions: job security has become an effective myth for most of those who can actually get work; long-term unemployment seems to have become structural and permanent. Consequently, the notions of lifelong learning and lifelong education have taken on dimensions far removed from the almost Utopian ideals of their supporters in the years following the publication of the report Learning to Be. Given the current economic gloom, the popularity of the terms with politicians and the fact of being in the European Year of Lifelong Learning, it is perhaps appropriate to take stock of the whole notion of lifelong learning and lifelong education and to see just what meaning (if any) lies behind these words and where they might take us in the future. This essay lays its foundations in the historical background to the ideas of lifelong learning and lifelong education before moving onto a critique of the post-Faure advocates of the principles. It discusses various problems inherent in the concepts (such as lifelong inadequacy) before concluding that, although many of the difficulties in the concepts are due to the confused nature of adult education itself (e.g. is it education or leisure?), there is a greater need than ever for sustained efforts in favour of lifelong education to help to restore the hope which seems to have become a rare commodity among an all too large section of society

Experiences with designing and managing organic rotation trials

This report was presented at the UK Organic Research 2002 Conference. Practical problems encountered in two long-term organic rotation trials at Aberdeen and Elgin are discussed. Compromises have had to be made in designing and managing the trials: how to include livestock and measure output, plot size, marking and fencing, discards and paths, replication, rotation length, randomisation of crop sequence, site uniformity, manoeuvrability of machines, soil compaction and exposure to pest damage

Effect of organic crop rotations on long-term development of the weed seedbank

Changes in the weed seedbank were monitored between 1991 and 1998 in two experiments that were established to compare organic crop rotations at two sites in NE Scotland. Two rotations, replicated twice at each site, were compared and all courses of both rotations were present every year. There were relatively minor changes in weed species diversity over time, but major changes in seedbank abundance. Weed seed numbers were relatively low in rotations with a high proportion of grass/clover ley. Differences in level of seedbank across the rotation were relatively predictable at Tulloch but much less so at Woodside where factors such as the effect of the grass/clover ley seemed to play a lesser role. Other factors, such as weather and its influence on the effectiveness of weed control operations, and higher populations of ground-living arthropods, may be affecting the Woodside seedbanks

A Direct Measurement of the Dust Extinction Curve in an Intermediate-Redshift Galaxy

We present a proof-of-concept study that dust extinction curves can be extracted from the infrared (IR), optical, ultraviolet (UV) and X-ray afterglow observations of GRBs without assuming known extinction laws. We focus on GRB 050525A (z = 0.606), for which we also present IR observations from the Spitzer Space Telescope at about 2.3 days post-burst. We construct the spectral energy distribution (SED) of the afterglow and use it to derive the dust extinction curve of the host galaxy in 7 optical/UV wavebands. By comparing our derived extinction curve to known templates, we see that the Galactic or Milky Way extinction laws are disfavored versus the Small and Large Magellanic Cloud (SMC and LMC) ones, but that we cannot rule out the presence of a LMC-like 2175 angstrom bump in our extinction curve. The dust-to-gas ratio present within the host galaxy of GRB 050525A is similar to that found in the LMC, while about 10 to 40% more dust is required if the SMC template is assumed. Our method is useful to observatories that are capable of simultaneously observing GRB afterglows in multiple wavebands from the IR to the X-ray.Comment: 9 pages, 5 figures. Accepted by ApJ.

Challenges of maternal and prenatal care in Nigeria

Background and aim: Evidence in the literature indicates that maternal health care by a skilled birth attendant is one of the key strategies for maternal survival. However, the rate of maternity care utilization and reduction of maternal death is very low in Nigeria. This study was designed to explored factors influencing women utilization of maternal and prenatal care in Nigeria. Hence, the need to understand factors that serves as barriers to accessing maternal and prenatal care in Nigeria using the Socio-ecological Model (SEM). Methods: A mixed method was employed for this study. Data collection used questionnaires and in-depth interviews. Questionnaires were distributed to 330 respondents of which 318 of them were retrieved and qualitative in-depth interviews were conducted for 6 participants. The study was conducted in one of the tertiary health facilities in Nigeria, amongst mothers aged 15-45 years. Statistical Package for Social Sciences (SPSS) was used in analyzing the quantitative data whilst a qualitative content analysis was done for the qualitative data. Results: The study established that education, income level, costs associated with seeking care, distance and time taken to travel were significantly associated with maternity health care services utilization. The study concludes that; costs of treatment, distance and time, income level, staff attitude and women’s autonomy were critical in determining women utilization of maternity care services

Is maternal nutrition knowledge more strongly associated with the diets of mothers or their school-aged children?

Objective Maternal nutrition knowledge has frequently been identified as an important target for nutrition promotion interventions. The aim of the present study was to investigate whether maternal nutrition knowledge is more strongly associated with the mother\u27s own diet or that of her child.Design Cross-sectional multivariate linear regression with interactions analyses of survey data.Setting Socio-economically disadvantaged neighbourhoods in Victoria, Australia.Subjects Five hundred and twenty-three mothers and their children who participated in the Resilience for Eating and Physical Activity Despite Inequality (READI) study, a cross-sectional survey study conducted in 2009 among women and their children residing in socio-economically disadvantaged neighbourhoods.Results In adjusted models, for three (vegetable, chocolate/lollies and soft drink consumption) out of the seven dietary outcomes assessed, there was a significant association between maternal nutrition knowledge and maternal diet, whereas for the children\u27s diets none of the seven outcomes were associated with maternal nutrition knowledge. Statistical comparison of regression coefficients showed no difference between the maternal nutrition knowledge–maternal diet association and the maternal nutrition knowledge–child diet association.Conclusions Promoting maternal nutrition knowledge may represent an important avenue for improving diet in mothers from socio-economically disadvantaged neighbourhoods, but more information is needed on how and when this knowledge is translated to benefits for their children\u27s diet

Charge pair dissociation and recombination dynamics in a P3HT–PC60BM bulk heterojunction

The authors thank the EPSRC, SUPA, the Condensed Matter Doctoral Training Centre and the European Union Seventh Framework programme (grant agreement 321305) for financial support.The mechanism by which Coulombically bound charge pairs dissociate into free carriers in photovoltaic donor–acceptor blends is of great interest. Here, we use polarization-sensitive transient absorption (TA) to study the diffusion of photogenerated holes in a polythiophene (P3HT)–fullerene (PC60BM) blend. We observe an initial anisotropy value of 0.4 for the absorption of photogenerated holes, indicating that holes generated on a 100 fs time scale are localized on the same polymer chain as their precursor excitons. Depolarization dynamics indicate fast initial hole motion on a 0.3 ps time scale and slower migration up to 100 ps. Charge pair recombination is found to occur on a much longer time scale of 10–1000 ns via a purely bimolecular process independent of excess energy. Our results show that nearly all charge pairs get separated by at least 7 nm in the absence of an external field and indicate that high charge mobility is crucial for charge separation.PostprintPeer reviewe
