Nurse Practitioners\u27 Characteristics and Job Satisfaction
PURPOSE: To identify demographics and job satisfaction levels of currently working nurse practitioners (NPs) in California. DATA SOURCES: A mail-in survey was used to gather data The Mueller McCloskey Satisfaction Scale was sent to a randomized sample of 200 California NPs with active licensure. Descriptive statistical analysis of usable data was employed. CONCLUSIONS: NPs reported high levels of job satisfaction. Aspects of the job that showed significant levels of satisfaction were schedules, flexibility of hours, and interprofessional relationships. NPs were least satisfied with not having professional opportunities such as participation in nursing research, writing/publishing, and belonging to a department/nursing committee
Compactly generating all satisfying truth assignments of a Horn formula
As instance of an overarching principle of exclusion an algorithm is
presented that compactly (thus not one by one) generates all models of a Horn
formula. The principle of exclusion can be adapted to generate only the models
of weight . We compare and contrast it with constraint programming,
integer programming, and binary decision diagrams.Comment: Considerably improves upon the readibility of the previous versio
Environment or Outflows? New insight into the origin of narrow associated QSO absorbers
Recent detailed studies of Narrow Absorption Line (NAL) systems in
QSO-spectra have revealed that at least 50% of QSOs have NALs associated with
the central engine, and in most cases they are found to be outflowing. Will
studies of NALs provide the much sort after evidence for ubiquitous QSO
feedback that can halt the formation of stars in galaxies? I present new
results on the distribution of line-of-sight velocity offsets between MgII
absorbers and their background QSOs, based on a large catalogue of absorbers
from SDSS DR6 and greatly improved QSO-redshift estimates. My analysis reveals
a high-velocity population of MgII NALs extending out to at least 6000 km/s
from the QSOs, which cannot be ascribed to the clustering of local galaxies,
similar to that observed recently for CIV absorbers. The very existence of such
low ionisation gas clouds in the intense ionising field of the QSO suggests
that we may indeed be witnessing the mechanical expulsion of gas, alongside the
heating previously observed. I also show that there is a significant excess of
low-velocity MgII NALs in radio-loud QSOs compared to radio-quiet QSOs. In the
near future, improved QSO clustering results will allow us to say whether this
is due to environmental or feedback effects.Comment: 10 pages, 5 figures, to appear in proceedings of the
