Characterization of Spatial Coherence of Synchrotron Radiation with Non-Redundant Arrays of Apertures

We present a method to characterize the spatial coherence of soft X-ray radiation from a single diffraction pattern. The technique is based on scattering from non-redundant arrays (NRA) of slits and records the degree of spatial coherence at several relative separations from one to 15 microns, simultaneously. Using NRAs we measured the transverse coherence of the X-ray beam at the XUV X-ray beamline P04 of the PETRA III synchrotron storage ring as a function of different beam parameters. To verify the results obtained with the NRAs additional Young's double pinhole experiments were conducted and show good agreement.Comment: 15 pages, 6 figures, 2 tables, 42 reference

Austerity and the lives of people with learning disabilities. A thematic synthesis of current literature

The Financial Crisis of 2008 resulted in many western economies implementing cuts in health and social care. This systematic review provides a holistic picture of the impact of austerity policy on the lives of people with learning disabilities (LD) and the collateral effects on the people who support them. Our review suggests that in the current climate of economic austerity, available funding to support people with LD is no longer aligned to their care needs. Cuts in disability services have adversely affected the well-being both of people with LD and their informal carers. Individuals with LD have lost social support and are experiencing increased social isolation. Heightened demands on family carers’ time have negatively influenced their wider roles, including parental functioning, and labour market participation. Our review provides the foundations for further discourse and research on the effects of austerity on people with LD and their family carers

An explanation of the underdevelopment of China’s service sector from the perspective of demand

The share of the service sector in China is significantly lower than that in most countries at the same level of income. Figures reveal that an insufficiency in both consumer and producer demand may be one of the reasons. We find that the demand insufficiency mainly stems from high consumer preferences for saving and China’s export-oriented trade structure. These excessive saving tendencies limit consumer demand for service products and thus hamper the development of consumer services in China. The rapid development of the processing trade also impedes the interrelation between the domestic manufacturing and service industries, reduces the effective demand for local producer services from the manufacturing industry, and ultimately restricts the growth of the producer service industry in China

Determinants and consequences of international migration

This chapter provides a simple overview of the canonical model of international migration, discusses the consequences of migration on both sending and receiving countries and draws some considerations on future research prospects for the international migration literature
