Wales should continue its efforts to reform the curriculum and raise the standards of teaching in order to improve the quality and equity of its school system, according to a new OECD report.

Ukraine has taken ambitious steps to tackle bribery and corruption across government, including public procurement and, law enforcement. It should now step up its efforts to tackle integrity risks and violations in education, such as unmerited grades, misappropriated school funds, and preferential access to schools and study programmes - according to a new OECD report.

Investing in skills is crucial for fostering inclusive economic growth and creating strong societies. In an increasingly connected world, skills are particularly important for citizens to get the most out of new forms of capital, such as big data and robotics.

Brazil’s old-age pensions have reduced old-age poverty below OECD levels, but pension expenditures of 8.2% of GDP are expected to rise rapidly as the population ages. A pension reform is necessary to ensure the financial sustainability of the system.

Successes and failures in the classroom will increasingly shape the fortunes of countries. And yet, more of the same education will only produce more of the same strengths and weaknesses.

This new Advisory Document replaces the 1995 consensus document on the Application of the Principles of GLP to Computerised Systems. It retains all of the key text from the original 1995 document, but includes new text to reflect the current state-of-the art in this field.

German database Information system für gefährliche Stoffe IGS is now linked to eChemPortal. The IGS provides public access to a variety of information on chemical and microbiological substances mostly in German. The focus is on regulatory information reflecting German and European, as well as Swiss, US and selected other legislation and assessments. Beside this, information on substance data and emergency procedures is available.

Deputy director of China's National Health Commission Li Bin said that reforms are underway to improve the country's disease prevention and control mechanisms.

Good design in any discipline usually carries a structure of order and harmony. Since the Renaissance, artists and architects have used a strong understanding of proportions to create aesthetically pleasing architecture. Many of these classical design principles have followed us into modern times and can be found today in effective web design.

Take an A4 piece of paper for example. If you take it and halve it, the resulting size is A5 with the same exact proportions. No other proportion has the same properties. 16th century architect, Andrea Palladio knew this well. It is believed that because, fundamentally, most architects—like Palladio—use a similar system of proportions to plan and design spaces, buildings can look very different while remaining similar at their cores.

A simple two-spindle based lathe system for the preparation of cylindrical samples intended for X-ray tomography is presented. The setup can operate at room temperature as well as under cryogenic conditions, allowing the preparation of samples down to 20 and 50 µm in diameter, respectively, within minutes. Case studies are presented involving the preparation of a brittle biomineral brachiopod shell and cryogenically fixed soft brain tissue, and their examination by means of ptychographic X-ray computed tomography reveals the preparation method to be mainly free from causing artefacts. Since this lathe system easily yields near-cylindrical samples ideal for tomography, a usage for a wide variety of otherwise challenging specimens is anticipated, in addition to potential use as a time- and cost-saving tool prior to focused ion-beam milling. Fast sample preparation becomes especially important in relation to shorter measurement times expected in next-generation synchrotron sources.

A portable IR fiber laser-heating system, optimized for X-ray emission spectroscopy (XES) and nuclear inelastic scattering (NIS) spectroscopy with signal collection through the radial opening of diamond anvil cells near 90°with respect to the incident X-ray beam, is presented. The system offers double-sided on-axis heating by a single laser source and zero attenuation of incoming X-rays other than by the high-pressure environment. A description of the system, which has been tested for pressures above 100 GPa and temperatures up to 3000 K, is given. The XES spectra of laser-heated Mg0.67Fe0.33O demonstrate the potential to map the iron spin state in the pressure–temperature range of the Earth's lower mantle, and the NIS spectra of laser-heated FeSi give access to the sound velocity of this candidate of a phase inside the Earth's core. This portable system represents one of the few bridges across the gap between laser heating and high-resolution X-ray spectroscopies with signal collection near 90°.

A review of recent and ongoing development and results within the field of biological solution small-angle X-ray scattering (BioSAXS), with a focus on the increasing complexity of biological samples, data collection and data evaluation strategies.

The title compound, C7H4F3NO2, 3-tri­fluoro­methyl-1H-pyrrolo­[1,2-c]oxazol-1-one, is the first crystal structure of the pyrrolo­[1,2-c]oxazole ring system: the fused ring system is almost planar (r.m.s. deviation = 0.006 Å). In the crystal, weak C—H⋯O and C—H⋯F hydrogen bonds link the mol­ecules into [001] chains and π–π stacking inter­actions consolidate the structure.

The local Fourier-space relation between diffracted intensity I, diffraction wavevector q and dose D, ilde I(q,D), is key to probing and understanding radiation damage by X-rays and energetic particles in both diffraction and imaging experiments. The models used in protein crystallography for the last 50 years provide good fits to experimental I(q) versus nominal dose data, but have unclear physical significance. More recently, a fit to diffraction and imaging experiments suggested that the maximum tolerable dose varies as q−1 or linearly with resolution. Here, it is shown that crystallographic data have been strongly perturbed by the effects of spatially nonuniform crystal irradiation and diffraction during data collection. Reanalysis shows that these data are consistent with a purely exponential local dose dependence, ilde I(q,D) = I0(q)exp[−D/De(q)], where De(q) ∝ qα with α ≃ 1.7. A physics-based model for radiation damage, in which damage events occurring at random locations within a sample each cause energy deposition and blurring of the electron density within a small volume, predicts this exponential variation with dose for all q values and a decay exponent α ≃ 2 in two and three dimensions, roughly consistent with both diffraction and imaging experiments over more than two orders of magnitude in resolution. The B-factor model used to account for radiation damage in crystallographic scaling programs is consistent with α = 2, but may not accurately capture the dose dependencies of structure factors under typical nonuniform illumination conditions. The strong q dependence of radiation-induced diffraction decays implies that the previously proposed 20–30 MGy dose limit for protein crystallography should be replaced by a resolution-dependent dose limit that, for atomic resolution data sets, will be much smaller. The results suggest that the physics underlying basic experimental trends in radiation damage at T ≃ 100 K is straightforward and universal. Deviations of the local I(q, D) from strictly exponential behavior may provide mechanistic insights, especially into the radiation-damage processes responsible for the greatly increased radiation sensitivity observed at T ≃ 300 K.
