Raising the participation age in historical perspective : Policy learning from the past?
The raising of the participation age (RPA) to 17 in 2013 and 18 in 2015 marks a historic expansion of compulsory education. Despite the tendency of New Labour governments to eschew historical understanding and explanation, RPA was conceived with the benefit of an analysis of previous attempts to extend compulsion in schooling. This paper assesses the value of a historical understanding of education policy. The period from inception to the projected implementation of RPA is an extended one which has crossed over the change of government, from Labour to Coalition, in 2010. The shifting emphases and meanings of RPA are not simply technical issues but connect to profound historical and social changes. An analysis of the history of the raising of the school leaving age reveals many points of comparison with the contemporary situation. In a number of key areas it is possible to gain insights into the ways in which the study of the past can help to comprehend the present: the role of human capital, the structures of education, in curriculum development and in terms of preparations for change
"Where the mask ends and the face begins is not certain": Mediating ethnicity and cheating geography in Jonny Steinberg's Little Liberia
Mixing historical commentary, reportage, biography and personal stories, South
African writer Jonny Steinberg takes up the tale of a fractured African nation and its
diaspora in Little Liberia: An African Odyssey in New York City (2011). The "little
Liberia" founded in New York's urban jungle may have represented, for many of its
inhabitants, a way to "cheat geography" by recreating a home away from home, but
Little Liberia shows the reader it has not allowed them to cheat history. The book
deals with the lives of two inhabitants of Park Hill Avenue on Staten Island, where
nearly everyone is Liberian. Their conflict threatens to implode the community, igniting
suspicions and accusations that had been bottled up since their exile. The article
focuses on the interface of mediated ethnicity and citizenship related to the struggle
for power in the diasporic Liberian community on Staten Island. Attention is also paid
to feelings of identity of Little Liberia's author.DHE
Mapping the genetic architecture of gene expression in human liver
Genetic variants that are associated with common human diseases do not lead directly to disease, but instead act on intermediate, molecular phenotypes that in turn induce changes in higher-order disease traits. Therefore, identifying the molecular phenotypes that vary in response to changes in DNA and that also associate with changes in disease traits has the potential to provide the functional information required to not only identify and validate the susceptibility genes that are directly affected by changes in DNA, but also to understand the molecular networks in which such genes operate and how changes in these networks lead to changes in disease traits. Toward that end, we profiled more than 39,000 transcripts and we genotyped 782,476 unique single nucleotide polymorphisms (SNPs) in more than 400 human liver samples to characterize the genetic architecture of gene expression in the human liver, a metabolically active tissue that is important in a number of common human diseases, including obesity, diabetes, and atherosclerosis. This genome-wide association study of gene expression resulted in the detection of more than 6,000 associations between SNP genotypes and liver gene expression traits, where many of the corresponding genes identified have already been implicated in a number of human diseases. The utility of these data for elucidating the causes of common human diseases is demonstrated by integrating them with genotypic and expression data from other human and mouse populations. This provides much-needed functional support for the candidate susceptibility genes being identified at a growing number of genetic loci that have been identified as key drivers of disease from genome-wide association studies of disease. By using an integrative genomics approach, we highlight how the gene RPS26 and not ERBB3 is supported by our data as the most likely susceptibility gene for a novel type 1 diabetes locus recently identified in a large-scale, genome-wide association study. We also identify SORT1 and CELSR2 as candidate susceptibility genes for a locus recently associated with coronary artery disease and plasma low-density lipoprotein cholesterol levels in the process. © 2008 Schadt et al
Economic liberalization and the antecedents of top management teams: evidence from Turkish 'big' business
There has been an increased interest in the last two decades in top management teams (TMTs) of business firms. Much of the research, however, has been US-based and concerned primarily with TMT effects on organizational outcomes. The present study aims to expand this literature by examining the antecedents of top team composition in the context of macro-level economic change in a late-industrializing country. The post-1980 trade and market reforms in Turkey provided the empirical setting. Drawing upon the literatures on TMT and chief executive characteristics together with punctuated equilibrium models of change and institutional theory, the article develops the argument that which firm-level factors affect which attributes of TMT formations varies across the early and late stages of economic liberalization. Results of the empirical investigation of 71 of the largest industrial firms in Turkey broadly supported the hypotheses derived from this premise. In the early stages of economic liberalization the average age and average organizational tenure of TMTs were related to the export orientation of firms, whereas in later stages, firm performance became a major predictor of these team attributes. Educational background characteristics of teams appeared to be under stronger institutional pressures, altering in different ways in the face of macro-level change
Active Amplification of the Terrestrial Albedo to Mitigate Climate Change: An Exploratory Study
This study explores the potential to enhance the reflectance of solar
insolation by the human settlement and grassland components of the Earth's
terrestrial surface as a climate change mitigation measure. Preliminary
estimates derived using a static radiative transfer model indicate that such
efforts could amplify the planetary albedo enough to offset the current global
annual average level of radiative forcing caused by anthropogenic greenhouse
gases by as much as 30 percent or 0.76 W/m2. Terrestrial albedo amplification
may thus extend, by about 25 years, the time available to advance the
development and use of low-emission energy conversion technologies which
ultimately remain essential to mitigate long-term climate change. However,
additional study is needed to confirm the estimates reported here and to assess
the economic and environmental impacts of active land-surface albedo
amplification as a climate change mitigation measure.Comment: 21 pages, 3 figures. In press with Mitigation and Adaptation

Rationale, design and methods of the Study of Work and Pain (SWAP): a cluster randomised controlled trial testing the addition of a vocational advice service to best current primary care for patients with musculoskeletal pain (ISRCTN 52269669)
Background
Musculoskeletal pain is a major contributor to short and long term work absence. Patients
seek care from their general practitioner (GP) and yet GPs often feel ill-equipped to deal with
work issues. Providing a vocational case management service in primary care, to support
patients with musculoskeletal problems to remain at or return to work, is one potential
solution but requires robust evaluation to test clinical and cost-effectiveness.
Methods/Design
This protocol describes a cluster randomised controlled trial, with linked qualitative
interviews, to investigate the effect of introducing a vocational advice service into general
practice, to provide a structured approach to managing work related issues in primary care
patients with musculoskeletal pain who are absent from work or struggling to remain in work.
General practices (n = 6) will be randomised to offer best current care or best current care
plus a vocational advice service. Adults of working age who are absent from or struggling to
remain in work due to a musculoskeletal pain problem will be invited to participate and 330
participants will be recruited. Data collection will be through patient completed
questionnaires at baseline, 4 and 12 months. The primary outcome is self-reported work
absence at 4 months. Incremental cost-utility analysis will be undertaken to calculate the cost
per additional QALY gained and incremental net benefits. A linked interview study will
explore the experiences of the vocational advice service from the perspectives of GPs, nurse
practitioners (NPs), patients and vocational advisors.
Discussion
This paper presents the rationale, design, and methods of the Study of Work And Pain
(SWAP) trial. The results of this trial will provide evidence to inform primary care practice
and guide the development of services to provide support for musculoskeletal pain patients
with work-related issues.

Measurement of the asymmetries in 3(¯e, e′p)d and 3(¯e, e′p)np
Abstract.: The electron target asymmetries A || and A⊥ with target spin parallel and perpendicular to the momentum transfer \ensuremath{\boldsymbol{q}} were measured for both the two- and three-body breakup of 3He in the 3 (¯e, e'p)-reaction. Polarized electrons were scattered off polarized 3He in the quasielastic regime in parallel kinematics with the scattered electron and the knocked-out proton detected using the Three-Spectrometer Facility at MAMI. The results are compared to Faddeev calculations which take into account Final-State Interactions as well as Meson Exchange Currents. The experiment confirms the prediction of a large effect of Final-State Interactions in the asymmetry of the three-body breakup and of an almost negligible one for the two-body breaku
Pesticides and health: A review of evidence on health effects, valuation of risks, and benefit‐cost analysis
In this paper, we provide reviews of recent scientific findings on health effects and preference valuation of health risks related to pesticides, and the role of benefit‐cost analysis in policies related to pesticides. Our reviews reveal that whereas the focus of the health literature has been on individuals with direct exposure to pesticides, e.g. farmers, the literature on preference elicitation has focused on those with indirect exposure, e.g. consumers. Our discussion of pesticides policies emphasizes the need to clarify the rationale for regulation and the role of risk perceptions in benefit‐cost analysis, and stress the importance of inter‐disciplinary research in this area
Hygienic characteristics of radishes grown in soil contaminated with Stenotrophomonas maltophilia
Background: Stenotrophomonas maltophilia is a plant growth-promoter. This bacterium is also implicated in human
diseases. Thus, after the use of this bacterium in agriculture, the safety of the final products has to be verified. Due to
the ubiquitous presence of S. maltophilia in soil, in this study a massive contamination was simulated to evaluate the
growth and safety of Raphanus sativus L..
Results: Different inoculums and soil treatment conditions were tested. Soils were analysed weekly and the radishes
at harvest for their microbial loads and presence/persistence of S. maltophilia LMG 6606. The concentration of the
bacterium added in the different trials decreased during the first week, but increased thereafter and determined a
significant increase of growth parameters of radishes.
Conclusions: The addition of S. maltophilia LMG 6606 to non-autoclaved soil enhanced the productivity of radishes.
The bacterium did not internalize in the hypocotyls, but colonized the external surface ensuring the safety of the
products. Thus, a sanitizing bath of hypocotyls before consumption is necessary
Oceanic loading of wildfire-derived organic compounds from a small mountainous river
Copyright 2008 by the American Geophysical Union.Small mountainous rivers (SMRs) export substantial amounts of sediment into the world's oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and compositionally unique. We report here excessively high loadings of polycyclic aromatic hydrocarbons (PAHs), lignin, and levoglucosan, discharged from the Santa Clara River into the Santa Barbara Channel. The abundance of PAHs, levoglucosan, and lignin in Santa Barbara Channel sediments ranged from 201.7 to 1232.3 ng gdw−1, 1.3 to 6.9 μg gdw−1, and 0.3 to 2.2 mg per 100 mg of the sedimentary OC, respectively. Assuming a constant rate of sediment accumulation, the annual fluxes of PAHs, levoglucosan, and lignin, to the Santa Barbara Channel were respectively, 885.5 ± 170.2 ng cm−2 a−1, 3.5 ± 1.9 μg cm−2 a−1 and 1.4 ± 0.3 mg per 100 mg OC cm−2 a−1, over ∼30 years. The close agreement between PAHs, levoglucosan, and lignin abundance suggests that the depositional flux of these compounds is largely biomass combustion-derived. To that end, use of the Santa Clara River as a model for SMRs suggests this class of rivers may be one of the largest contributors of pyrolyzed carbon to coastal systems and the open ocean. Wildfire associated carbon discharged from other high yield fluvial systems, when considered collectively, may be a significant source of lignin, pyrolytic PAHs, and other pyrogenic compounds to the ocean. Extrapolating these methods over geologic time may offer useful historical information about carbon sequestration and burial in coastal sediments and affect coastal carbon budgets
