The control of calcium metabolism by parathyroid hormone, calcitonin and vitamin D
Advances in analysis of chemistry and physiology of parathyroid hormone, calcitonin, and Vitamin D are described along with development of techniques in radioassay methods. Emphasis is placed on assessment of normal and abnormal patterns of secretion of these hormones in specific relation to the physiological adaptations of weightlessness and space flight. Related diseases that involve perturbations in normal skeletal and calcium homeostasis are also considered
Physical implementations of quantum absorption refrigerators
Absorption refrigerators are autonomous thermal machines that harness the
spontaneous flow of heat from a hot bath into the environment in order to
perform cooling. Here we discuss quantum realizations of absorption
refrigerators in two different settings: namely, cavity and circuit quantum
electrodynamics. We first provide a unified description of these machines in
terms of the concept of virtual temperature. Next, we describe the two
different physical setups in detail and compare their properties and
performance. We conclude with an outlook on future work and open questions in
this field of research.Comment: Patrick P. Potts was formerly known as Patrick P. Hofe

EFFECTS OF BANKING STRUCTURE ON THE ALLOCATION OF CREDIT TO NONMETROPOLITAN COMMUNITIES
Recent and proposed legislative changes encourage increases in multioffice banking activity. In this manuscript, the allocation of credit to nonmetropolitan communities in a branch banking state (Arizona) is compared to that in a unit banking-holding company state (Colorado). Rapidly growing nonmetropolitan areas have experienced increased lending activity under statewide branching relative to unit banking. Rural communities, which experienced slow or negative growth, had lower loan-to-deposit rations under branch banking than might have existed under unit banking. Therefore, conversion to branch banking may result in a reallocation of loanable funds within nonmetropolitan areas.Financial Economics,
A meta-narrative review of electronic patient records
This session comprises four papers that consider how systematic review methods may be
developed in order to make the best use of complex evidence in education and health.
The methods and approaches reflected upon in these papers are not drawn from a single
research tradition, but share a common goal of broadening the methodological scope of
systematic reviews and better understanding the utilisation of knowledge produced in this
way. The first paper (Henry Potts) reports an ongoing review using a meta-narrative
approach to make sense of the diverse sources of knowledge regarding electronic patient
records. The review method has stressed the importance of understanding knowledge
from within the research tradition in which it was produced; it is argued that this has
important implications for the way that evidence is utilised in the policy making process.
The second paper (Geoff Wong) reflects upon the experience of using an explicit realist
approach in the synthesis of the evidence in Internet based learning. This realist synthesis
offers a method of making sense of the highly heterogeneous and context dependent
evidence which exists in this field thus enabling greater insights into what makes such
educational interventions ‘work’. The third paper (Rod Sheaff) reports a review of the
predominantly qualitative research literature on organisational structures and their
impacts upon policy outcomes in health systems. A scoping study found 14389 relevant
papers of which 1568 were selected for review. These studies were very variable in the
amount and quality of the qualitative data, hence 'evidence', which they reported. The
paper describes an attempt to adapt realist methods so as to synthesise such bodies of
research in ways which take account of this variation in the strength of qualitative
evidence. The fourth paper (Mark Pearson) draws upon the work of Donald Campbell
and colleagues in order to gain a fuller understanding of how systematic reviews are
utilised in the policy making process. It is argued that interpretive approaches to
understanding policy making (such as rhetorical analysis) need to be tempered with a
more nuanced understanding of research validity. The case is made that interpretive
approaches not only can, but should, be melded with research validity to increase
understanding of the policy making process
