Can we detect Li K X-ray in lithium compounds using energy dispersive spectroscopy?

Lithium is the key element for the development of battery and new technology and the development of an analytical technique to spatially and quantitatively resolve this element is of key importance. Detection of Li K in pure metallic lithium is now possible in the Scanning Electron Microscope (SEM) with newly designed Energy Dispersive Spectroscopy (EDS). However, this work is clearly showing, for the first time using EDS, the detection of Li K in several binary lithium compounds (LiH, Li N, Li S, LiF and LiCl).

More reliable inference for the dissimilarity index of segregation.

The most widely used measure of segregation is the so-called dissimilarity index. It is now well understood that this measure also reflects randomness in the allocation of individuals to units (i.e.

Child health: evidence on the roles of family income and maternal mental health from a UK birth cohort.

There is a growing literature showing an association between higher family income and better child health. This paper uses cohort data with rich information on mother's early life events, her health, child-health-related behaviours, and her child's health to examine this association for the UK and to identify some of the mechanisms through which income affects child health. The paper examines the cross-sectional association between income and health, finds the expected association, but concludes that the association with current income cannot be distinguished from one between permanent income and child health.

Local neighbourhood and mental health: evidence from the UK.

This paper examines the association between neighbourhood and levels and changes in common mental disorders. Using data from a large scale nationally representative survey of individuals and households (the British Household Panel Survey), it locates individuals in their local neighbourhoods. These are defined as the nearest 500-800 persons centered around each individual in the survey.
