Girls’ and women’s education within Unesco and the World Bank, 1945–2000

By 2000, girls’ and women’s education was a priority for international development organisations. While studies have examined the impact of recent campaigns and programmes, there has been less exploration of ideas about girls’ and women’s education within development thought in the immediate post?colonial period, and the political mechanisms through which this came to be a global concern. Through a study of policy documents, this paper investigates how the education of girls and women came to be prioritised within the two principle UN agencies involved with education since 1945, the World Bank and Unesco. A shift in priorities is evident, from ensuring formal rights and improving the status of women, to expanding the productive capacities of women, fertility control and poverty reduction. While the ascendance of human capital theory provided a space for a new perception of the role of women’s education in development, in other policy arenas women’s education was central to exploring more substantive, rights?based notions of gender equality. Ultimately, the goal of improving girls’ and women’s education fitted into diverse development agendas, paving the way for it to become a global development priority

Failing boys and moral panics: perspectives on the underachievement debate

The paper re-examines the underachievement debate from the perspective of the ‘discourse of derision’ that surrounds much writing in this area. It considers the contradictions and inconsistencies which underpin much of the discourse – from a reinterpretation of examination scores, to the conflation of the concepts of ‘under’ and ‘low’ achievement and finally to the lack of consensus on a means of defining and measuring the term underachievement. In doing so, this paper suggests a more innovative approach for understanding, re-evaluating and perhaps rejecting the notion of underachievement

Fermeture de phase en astronomie optique

On envisage des simplifications aux techniques récemment proposées afin d'utiliser la « fermeture de phase » en astronomie optique, techniques visant à obtenir la limite théorique de diffraction en imagerie . La méthode envisagée permet de corriger des images isolées, obtenues à courte exposition et dégradées par la turbulence atmosphérique, jusqu'à la limite de diffraction malgré la traversée de l'atmosphère terrestre . Elle prend toute son importance lorsqu'on l'applique à obtenir des images de haute résolution à partir d'une orbite autour de la Terre sans qu'il soit nécessaire de disposer à bord du satellite d'une surface de haute précision optique sur une grande ouverture . A la base de cette méthode : un interféromètre à pupilles multiples, comportant suffisament de redondances internes pour pouvoir séparer les paramètres de l'objet de ceux de l'instrument, chacun étant déterminé alors sans introduire de modèles a priori . Pour une application spatiale, le champ pourrait être dédoublé au moyen de séparateurs et de retards optiques autorisant des mesures à large bande. Une source de référence permet alors dans l'un des champs la stabilisation active de l'instrument - une précision de 1/100 de longueur d'onde paraît accessible, en étudiant une configuration praticable, sur une étoile de magnitude inférieure a 12 . L'autre champ est alors disponible pour de longues intégrations sur des objects faibles .Simplifications of recently proposed techniques for using phase closure to achieve diffraction-limited imaging in optical astronomy are considered . The technique permits synthesis of diffraction-limited images from single, short-exposure, turbulence-degraded images of bright objects viewed through the earth's atmosphere, but is more important as a method for obtaining high resolution images from earth-orbit without the need to put a single large aperture of accurate figure in space . The basis of the method is a multi-aperture interferometer with sufficient redundancy built into the instrument to permit the separation of instrumental and object dependent parameters and thus to permit each of these to be determined without recourse to model building. By use of image-slicing and optical delay lines it is possible to achieve broad-band imaging in two sub-fields . One of the sub-fields may be used as a reference to "shape lock" the instrument to x ./100 accuracy on a source of magnitude < 12, whilst the other is used to obtain long integrations on faint objects

Gender equality and girls education: Investigating frameworks, disjunctures and meanings of quality education

The article draws on qualitative educational research across a diversity of low-income countries to examine the gendered inequalities in education as complex, multi-faceted and situated rather than a series of barriers to be overcome through linear input–output processes focused on isolated dimensions of quality. It argues that frameworks for thinking about educational quality often result in analyses of gender inequalities that are fragmented and incomplete. However, by considering education quality more broadly as a terrain of quality it investigates questions of educational transitions, teacher supply and community participation, and develops understandings of how education is experienced by learners and teachers in their gendered lives and their teaching practices. By taking an approach based on theories of human development the article identifies dynamics of power underpinning gender inequalities in the literature and played out in diverse contexts and influenced by social, cultural and historical contexts. The review and discussion indicate that attaining gender equitable quality education requires recognition and understanding of the ways in which inequalities intersect and interrelate in order to seek out multi-faceted strategies that address not only different dimensions of girls’ and women’s lives, but understand gendered relationships and structurally entrenched inequalities between women and men, girls and boys

‘My language … I don’t know how to talk about it’: children’s views on language diversity in primary schools in France and England

This article investigates the ways in which children from immigrant backgrounds view the place of ‘other’ languages in primary schools in France and England. This article draws on findings from a cross-national ethnographic study, which investigated the experiences of 10- and 11-year-old children of immigrants in two primary schools, one in France and one in England. It shows how, in both schools, children had to negotiate the symbolic domination of a single legitimate language and viewed their other languages as inferior, undesirable or illicit. Building on the work of Pierre Bourdieu, findings in this paper contribute insights into the complex debates around language diversity, multilingualism and intercultural communication in schools in France and England

Predicting Concentrations of Organic Chemicals in Fish by Using Toxicokinetic Models

Quantification of chemical toxicity continues to be generally based on measured external concentrations. Yet, internal chemical concentrations have been suggested to be a more suitable parameter. To better understand the relationship between the external and internal concentrations of chemicals in fish, and to quantify internal concentrations we compared three. toxicokinetic (TK) models with each other and with literature data of measured concentrations of 39 chemicals. Two one, compartment models, together with the physiologically based toxicokinetic (PBTK) model, in which we improved the treatment of lipids, were used to predict concentrations of organic chemicals in two fish species: rainbow trout (Oncorhynchus mykiss) and fathead minnow (Pimephales promelas). All models predicted the measured internal concentrations in fish within I order of magnitude for at least 68% of the chemicals. Furthermore, the PBTK model outperformed the one-compartment models with respect to simulating chemical concentrations in the whole body (at least 88% of internal concentrations were predicted within 1 order of magnitude using the PBTK model). All the models can be used to predict concentrations in different fish species without additional experiments. However, further development of TK models is required for polar, ionizable, and easily biotransformed compounds

Merozoite surface protein-3α is a reliable marker for population genetic analysis of Plasmodium vivax

BACKGROUND: The knowledge on population structure of the parasite isolates has contributed greatly to understanding the dynamics of the disease transmission for designing and evaluating malaria vaccines as well as for drug applications. msp-1 and msp-3α genes have been used as a genetic marker in population studies of Plasmodium vivax isolates. In this study, msp-3α was compared and assessed with msp-1 marker in order to find whether msp-3α is a reliable genetic marker for P. vivax population studies. METHODS: This comparative study was designed and carried out as the first assessment of diversity in Pvmsp-3α gene by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in the 50 northern and 94 southern P. vivax isolates from Iran, which had been analysed before for msp-1 gene. RESULTS: Three allele size as, Type A (1.8 kb), Type B (1.5 kb) and Type C (1.2 kb) have been detected among both northern and southern isolates based on PCR results. Type C (70%) and Type A (68.7%) were the predominant fragments among northern and southern parasites, respectively. 99 distinct Pvmsp-3α fragments defined by the size were detected in the 94 southern samples by PCR analysis. However, no mixed genotype infections have been detected among northern isolates. Based on restriction pattern from digestion with Hha I and Alu I 12 and 49 distinct allelic variants have been detected among 50 northern and 94 southern isolates. However, based on msp-1 gene, 30 distinct variants identified in all 146-sequenced Iranian P. vivax isolate. CONCLUSION: The results suggested that PCR-RFLP on msp-3α gene is an adequate, applicable and easily used technique for molecular epidemiology studies of P. vivax isolates without the need for further sequencing analysis

Organic waste as a sustainable feedstock for platform chemicals

Biorefineries have been established since the 1980s for biofuel production, and there has been a switch lately from first to second generation feedstocks in order to avoid the food versus fuel dilemma. To a lesser extent, many opportunities have been investigated for producing chemicals from biomass using by-products of the present biorefineries, simple waste streams. Current facilities apply intensive pre-treatments to deal with single substrate types such as carbohydrates. However, most organic streams such as municipal solid waste or algal blooms present a high complexity and variable mixture of molecules, which makes specific compound production and separation difficult. Here we focus on flexible anaerobic fermentation and hydrothermal processes that can treat complex biomass as a whole to obtain a range of products within an integrated biorefinery concept
