This study aims to understand how characteristics of a labor flow network affect firm productivity using an inter-firm hiring network constructed from individual job histories. We separate IT-labor from non-IT labor and use the network measures constructed from the two types of labor flow to evaluate how they affect firm performance. We find that hiring IT workers from a diverse set of firms ca...

Collisional processes and details of atomic structure of heavy many-electron atoms and ions are not yet understood in a fully satisfying manner. Experimental studies are required for guiding new theoretical approaches. In response to fusion-related needs for collisional and spectroscopic data on tungsten atoms in all charge states, a project has been initiated in which electron-impact and photo...

Journal Impact Factor (JIF) has been used in assessing scientific journals. Other indices, h- and g-indices and Article Influence Score (AIS), have been developed to overcome some limitations of JIF. The aims of this study were, first, to critically assess the use of JIF and other parameters related to medical education research, and second, to discuss the capacity of these indices in assessing...

Theory suggests that neighborhood effects depend not only on where individuals live today, but also on where they lived in the past. Previous research, however, usually measures neighborhood context only once and does not account for length of residence, thereby understating the detrimental effects of long-term neighborhood disadvantage. This study investigates effects of duration of exposure t...

OBJECTIVES The Quality of Well-Being questionnaire is a measure of health-related quality of life (HRQoL) that has several desirable properties. Its widespread use has been hindered because it is difficult to administer. To overcome this limitation, a new self-administered form has recently been developed. This study examined the feasibility of using the Quality of Well-Being-Self-Administered ...

OBJECTIVES With health inequalities high on the policy agenda, this study measures oral health inequalities in the UK. METHODS We compare an objective clinical measure of oral health (number of natural teeth) with a self-reported measure of the impact of oral health (the Oral Health Impact Profile, OHIP) to establish whether the type of measure affects the scale of inequality measured. Gini c...

Accurate modeling of impact-ionization is a critical issue for submicron devices. It is well known that models based on the electric field or on the average carrier energy give a rather poor description of the problem. We show that by accounting for the average square energy an accurate analytical description of the distribution function can be given which can then be used to evaluate microscop...

BASIC CONCEPTS It has long been recognised that health and its determinants are strongly influenced by policies outside the healthcare sector, for example, transport, regeneration projects, and housing. In recent years, several countries have introduced health impact assessment (HIA) to try and ensure that potential effects on health are taken into account. It involves identifying disbenefits a...
