A dirty, rundown environment has quantifiable costs for the economy and the well-being of societies. For example, the welfare costs of air pollution from road transport alone are estimated to amount to around 1.7 trillion USD in OECD countries, 1.4 trillion USD in China and 0.5 trillion in India.

This report provides a review of recent firm-level and plant-level surveys containing questions on environmental policies, innovation practices or performance which are relevant for environmental policy analysis and assessment. We specifically focus on the core element that relates environmental policies to environmental and economic performance, namely the adoption of innovative practices and environmental innovations by firms.

Peru is a multicultural, megadiverse country, with abundant ecosystem and natural resources, and an ancient tradition in the sustainable management of its resources. Growing pressures from extractive industries, unplanned urbanisation and deforestation are threatening its natural heritage and the population's well-being.

In a drive to raise the quality of classroom teaching and boost student performance, Dutch education authorities are encouraging teachers to learn from each other through a process of peer review.

Students who know how to summarise information tend to perform better in reading. If disadvantaged students used effective learning strategies to the same extent as students from more advantaged backgrounds do, the performance gap between the two groups would be almost 20% narrower.

Most students enjoy orderly classrooms for their language-of-instruction lessons. Socio-economically disadvantaged students are less likely to enjoy orderly classrooms than advantaged students. Orderly classrooms – regardless of the school’s overall socio-economic profile – are related to better performance.

The story of Korean education over the past 50 years is one of remarkable growth and achievement. Korea is one of the top performing countries in the Programme for International Student Assessment (PISA) survey and among those with the highest proportion of young people who have completed upper secondary and tertiary education.

How educational resources are allocated is just as important as the amount of resources available.

Countries where 15-year-old students perform at high standards internationally tend to be the same countries where these young adults tend to perform well at the age of 26 to 28.

The share of students with an immigrant background increased between 2003 and 2012, both in traditional and new destination countries. The performance difference in mathematics between immigrant and non-immigrant students decreased, on average, between 2003 and 2012.

Archived webinar - Low-performing Students: Why they Fall Behind and How to Help them Succeed (February 10, 2016) with Andreas Schleicher, Director for Education and Skills, OECD, and Daniel Salinas, Analyst, OECD.

No country or economy participating in PISA 2012 can claim that all of its 15-year-old students have achieved basic proficiency skills in mathematics, reading and science. Some 28% of students score below the baseline level of proficiency in at least one of those subjects, on average across OECD countries

The Slovak Republic has undertaken a series of reforms to improve its education system, and the country now needs to use resources more efficiently and improve equity and inclusion in schools, according to a new OECD report.

In a rapidly changing world, having a strong knowledge base in their subject area, good classroom management skills and a commitment to helping students learn may no longer be enough to meet the expanding role of teachers.

In countries that performed above the OECD average in science, at least 80% of the students are in schools that invite specialists to conduct teacher training or organise in-service workshops for teachers or where teachers cooperate with each other. This is higher, on average, than what is observed among other countries.

As this month’s PISA in Focus reveals, students spend considerably more time learning in some countries than in others, but this does not necessarily translate into better learning outcomes.

Standardised tests help measure student’s progress at school and can inform education policy about existing shortfalls. However, too much testing could lead to much pressure on students and teachers to learn and teach for a test, something that would take the joy out of the learning process.

X-ray double-crystal monochromators face a shift of the exit beam when the Bragg angle and thus the transmitted photon energy changes. This can be compensated for by moving one or both crystals accordingly. In the case of monolithic channel-cut crystals, which exhibit utmost stability, the shift of the monochromated beam is inevitable. Here we report performance tests of novel, asymmetrically cut, channel-cut crystals which reduce the beam movements by more than a factor of 20 relative to the symmetric case over the typical energy range of an EXAFS spectrum at the Cu K-edge. In addition, the presented formulas for the beam offset including the asymmetry angle directly indicate the importance of this value, which has been commonly neglected so far in the operation of double-crystal monochromators.

An alternative approach to hard-X-ray photoelectron spectroscopy (HAXPES) has been established. The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D to 3D. A high-energy momentum microscope detects electrons with initial kinetic energies up to 8 keV with a k-resolution of 0.025 Å−1, equivalent to an angular resolution of 0.034°. A special objective lens with k-space acceptance up to 25 Å−1 allows for simultaneous full-field imaging of many Brillouin zones. Combined with time-of-flight (ToF) parallel energy recording this yields maximum parallelization. Thanks to the high brilliance (1013 hν s−1 in a spot of <20 µm diameter) of beamline P22 at PETRA III (Hamburg, Germany), the microscope set a benchmark in HAXPES recording speed, i.e. several million counts per second for core-level signals and one million for d-bands of transition metals. The concept of tomographic k-space mapping established using soft X-rays works equally well in the hard X-ray range. Sharp valence band k-patterns of Re, collected at an excitation energy of 6 keV, correspond to direct transitions to the 28th repeated Brillouin zone. Measured total energy resolutions (photon bandwidth plus ToF-resolution) are 62 meV and 180 meV FWHM at 5.977 keV for monochromator crystals Si(333) and Si(311) and 450 meV at 4.0 keV for Si(111). Hard X-ray photoelectron diffraction (hXPD) patterns with rich fine structure are recorded within minutes. The short photoelectron wavelength (10% of the interatomic distance) `amplifies' phase differences, making full-field hXPD a sensitive structural tool.

MAX IV is a fourth-generation, or diffraction-limited, synchrotron light source with a number of state-of-the-art beamlines. The performance of a beamline is, to a high degree, set by the energy resolution it can achieve, which in turn is governed to a large extent by the monochromator. During the design phase of a monochromator, the mechanical requirements must be fully understood and met with margin. During commissioning, the performance must be verified and optimized. In this paper, six soft X-ray monochromators at MAX IV beamlines (Bloch, Veritas, HIPPIE, SPECIES, FinEstBeAMS and SoftiMAX) are examined with a focus on their resolving power, energy range and the time required to change measurement range, as those parameters are dependent on each other. The monochromators have a modern commercial design, planned and developed in close collaboration with the vendors. This paper aims to present the current status of the commissioning at MAX IV with emphasis on elucidating the mechanical limitations on the performance of the monochromators. It contains analysis of the outcome and our approach to achieve fast and high-resolution monochromators.

The conventional approach to search-model identification in molecular replacement (MR) is to screen a database of known structures using the target sequence. However, this strategy is not always effective, for example when the relationship between sequence and structural similarity fails or when the crystal contents are not those expected. An alternative approach is to identify suitable search models directly from the experimental data. SIMBAD is a sequence-independent MR pipeline that uses either a crystal lattice search or MR functions to directly locate suitable search models from databases. The previous version of SIMBAD used the fast AMoRe rotation-function search. Here, a new version of SIMBAD which makes use of Phaser and its likelihood scoring to improve the sensitivity of the pipeline is presented. It is shown that the additional compute time potentially required by the more sophisticated scoring is counterbalanced by the greater sensitivity, allowing more cases to trigger early-termination criteria, rather than running to completion. Using Phaser solved 17 out of 25 test cases in comparison to the ten solved with AMoRe, and it is shown that use of ensemble search models produces additional performance benefits.

A complete method of comprehensive and quantitative evaluation of through-silicon via reliability using a highly sensitive phase-contrast X-ray microtomography was established. Quantitative characterizations include 3D local morphology and overall consistency of statistics.

The Python programming language, combined with the numerical computing library NumPy and the scientific computing library SciPy, has become the de facto standard for scientific computing in a variety of fields. This popularity is mainly due to the ease with which a Python program can be written and executed (easy syntax, dynamical typing, no compilation etc.), coupled with the existence of a large number of specialized third-party libraries that aim to lift all the limitations of the raw Python language. NumPy introduces vector programming, improving execution speeds, whereas SciPy brings a wealth of highly optimized and reliable scientific functions. There are cases, however, where vector programming alone is not sufficient to reach optimal performance. This issue is addressed with dedicated compilers that aim to translate Python code into native and statically typed code with support for the multi-core architectures of modern processors. In the present article it is shown how these approaches can be efficiently used to tackle different problems, with increasing complexity, that are relevant to crystallography: the 2D Laue function, scattering from a strained 2D crystal, scattering from 3D nanocrystals and, finally, diffraction from films and multilayers. For each case, detailed implementations and explanations of the functioning of the algorithms are provided. Different Python compilers (namely NumExpr, Numba, Pythran and Cython) are used to improve performance and are benchmarked against state-of-the-art NumPy implementations. All examples are also provided as commented and didactic Python (Jupyter) notebooks that can be used as starting points for crystallographers curious to enter the Python ecosystem or wishing to accelerate their existing codes.

Over the past decade, ptychography has been proven to be a robust tool for non-destructive high-resolution quantitative electron, X-ray and optical microscopy. It allows for quantitative reconstruction of the specimen's transmissivity, as well as recovery of the illuminating wavefront. Additionally, various algorithms have been developed to account for systematic errors and improved convergence. With fast ptychographic microscopes and more advanced algorithms, both the complexity of the reconstruction task and the data volume increase significantly. PtychoShelves is a software package which combines high-level modularity for easy and fast changes to the data-processing pipeline, and high-performance computing on CPUs and GPUs.
