Spacelab software development and integration concepts study report, volume 1

The proposed software guidelines to be followed by the European Space Research Organization in the development of software for the Spacelab being developed for use as a payload for the space shuttle are documented. Concepts, techniques, and tools needed to assure the success of a programming project are defined as they relate to operation of the data management subsystem, support of experiments and space applications, use with ground support equipment, and for integration testing

Margins within margins?: voices Speaking through a study of the provision of an educational program for the children of one Australian show circuit

This paper examines the tactics used by the Showmen's Guild of Australasia in successfully lobbying for the development of a distance education program for their children. The Guild is considered to be a 'marginalized' group, meaning members have less access to wealth, power, and status. Since 1930, members of the Showmen's Guild and their families have traveled from town to town providing agricultural and equestrian shows. Despite the diversity of backgrounds and experiences among people connected with the show circuit, the Guild is highly organized and has been politically active. Informal sanctions have been effective in enforcing group discipline and in presenting the image of a single body of opinion. In addition, investment in sophisticated machinery and technology has resulted in show people having the financial resources to buy homes and have a political voice via more 'normalized channels'. Although members learn early that they are a marginalized group and are perceived as different from the mainstream, the group maintains close ties and often celebrates its difference. Implications for educational program development center on the goals of educational programs designed for disadvantaged groups, and the status of other marginalized groups and their efforts to contest their marginalized status.

Control of broad-area vertical-cavity surface emitting laser emission by optically induced photonic crystals

We control the emission properties of a broad-area vertical-cavity surface emitting laser by coupling it to an external feedback cavity containing a photorefractive crystal with an optically induced photonic lattice. The periodic modulation of the refractive index serves as a tunable filter and enables the dynamic suppression of unwanted spatial instabilities and modes, as originally suggested by Gomila et al

Schools and learning in rural India and Pakistan: Who goes where, and how much are they learning?

It is increasingly recognised that there is a global learning crisis. We investigate this learning crisis through a comparative analysis of rural India and Pakistan. Using data from each country’s Annual Status of Education Report, we demonstrate that socio-economic status and gender are important determinants of whether children are in school or not, the type of school they attend, and whether or not they are learning. While learning varies across the type of school attended, socioeconomic disparities predominate: disadvantaged children in private schools are learning less than more advantaged children in government schools. Gender plays an important role, with disparities between boys and girls being most pronounced among poorer children in Pakistan. In addition, while private tuition improves learning for all children, it does not resolve socio-economic and gender disparities. This study draws attention to the need for policymakers to focus their attention on government schools in both countries given that this is not only where the majority of the poorest children are studying, but also where learning levels are lowest. The fact that rich children in government schools are learning indicates that we ought not to dismiss out-of-hand the role that government schools can play in learning.This is the author accepted manuscript.

Does private schooling narrow wealth inequalities in learning outcomes? Evidence from East Africa

In many low- and lower-middle-income countries, private schools are often considered to offer better quality of education than government schools. Yet, there is a lack of evidence to date on their role in reducing inequalities: namely, the extent to which private schooling improves learning among the most disadvantaged children. Our paper uses household survey data from Kenya, Tanzania, and Uganda to identify whether any observed impact of private schooling on core literacy and numeracy skills differs according to children’s household wealth. We demonstrate wealth gaps in access to private schooling, and use inferential models to account for observable differences between those who do and do not enrol in private schools. In Kenya and Uganda, we find that private schooling appears to improve the chances of children learning relative to their peers in government schools, but the chances of the poorest children learning in private schools remains low and is at best equivalent to the richest learning in government schools. In Tanzania, private schooling does not seem to improve poorer children’s learning, whereas it does for richer children. These findings raise a caution about the extent to which private provision can help narrow learning inequalities

Interpretation of x-ray-absorption dichroism experiments

A rule is derived to use x-ray magnetic circular dichroism spectra to extract the magnetic moment of the conduction-band states with j= l -1/2 separately from those with j= l + 1/2 as a function of energy. This quantity is straightforward to determine from the electronic band structure. The rule is illustrated with an application to pure iron and to the random substitutional alloy Fe_{80}CO_{20}

Screening of a HUVEC cDNA library with transplant-associated coronary artery disease sera identifies RPL7 as a candidate autoantigen associated with this disease.

A HUVEC cDNA library was screened with sera from two patients who had developed transplant-associated coronary artery disease (TxCAD) following cardiac transplantation. A total of six positive clones were isolated from a primary screen of 40 000 genes. Subsequent DNA sequence analysis identified these to be lysyl tRNA synthetase, ribosomal protein L7, ribosomal protein L9, beta transducin and TANK. Another gene whose product could not be identified showed homology to a human cDNA clone (DKFZp566M063) derived from fetal kidney. Full-length constructs of selected genes were expressed as his-tag recombinant fusion proteins and used to screen a wider patient base by ELISA to determine prevalence and association with TxCAD. Of these ribosomal protein L7 showed the highest prevalence (55.6%) with TxCAD sera compared to 10% non-CAD

Biodiversity and Ecosystem Health of the Aldabra Group, Southern Seychelles: Scientific Report to the Government of Seychelles.

National Geographic's Pristine Seas project, in collaboration with the government of the Seychelles, the Island Conservation Society (ICS), the Seychelles Islands Foundation (SIF), and the Waitt Foundation, conducted an expedition to explore the poorly known marine environment around these islands. The goals were to assess the biodiversity of the nearshore marine environment and to survey the largely unknown deep sea realm. The data collected contribute to the marine spatial planning of the Seychelles, in particular the creation of large marine reserves
