A global climatology of wind–wave interaction

Generally, ocean waves are thought to act as a drag on the surface wind so that momentum is transferred downwards, from the atmosphere into the waves. Recent observations have suggested that when long wavelength waves, characteristic of remotely generated swell, propagate faster than the surface wind momentum can also be transferred upwards. This upward momentum transfer acts to accelerate the near-surface wind, resulting in a low-level wave-driven wind jet. Previous studies have suggested that the sign reversal of the momentum flux is well predicted by the inverse wave age, the ratio of the surface wind speed to the speed of the waves at the peak of the spectrum. ECMWF ERA-40 data has been used here to calculate the global distribution of the inverse wave age to determine whether there are regions of the ocean that are usually in the wind-driven wave regime and others that are generally in the wave-driven wind regime. The wind-driven wave regime is found to occur most often in the mid-latitude storm tracks where wind speeds are generally high. The wave-driven wind regime is found to be prevalent in the tropics where wind speeds are generally light and swell can propagate from storms at higher latitudes. The inverse wave age is also a useful indicator of the degree of coupling between the local wind and wave fields. The climatologies presented emphasise the non-equilibrium that exists between the local wind and wave fields and highlight the importance of swell in the global oceans

A changing culture? Qualitative methods teaching in U.K. psychology

This paper surveys the landscape of qualitative methods teaching in U.K. psychology. First, we provide an overview of the administrative framework for this teaching and highlight the positive development that is the stipulation by key national bodies that undergraduate psychology programs should teach qualitative methods. Second, we discuss an attempt to meet the needs for training and resources that resulted from these stipulations and note how recent changes in the higher education funding landscape have made it more difficult to meet these needs. Third, we review literature on the teaching of qualitative methods in U.K. psychology departments and note the relative paucity of studies addressing this issue. In conclusion, we suggest that the key issue remains the stubbornness of the “quantitative culture” in many departments. The official bureaucratic infrastructure of U.K. psychology teaching may now mandate that qualitative methods be taught, but the tentative conclusions that can be drawn from what literature there is suggest that this obscures various practices at the departmental level, with many programs still providing little more than tokenistic engagement with qualitative methods.

Elastic electron scattering from formic acid (HCOOH): absolute differential cross-sections

We report experimental results for electron scattering from formic acid (HCOOH). A set of differential cross-sections is provided for elastic scattering at incident electron energies from 1.8 to 50 eV. Integral and momentum transfer cross-sections have also been derived from these results. Our results are compared, where possible, with recent theoretical calculations

Naturopathic Physician Attitudes and Practices for Vaccination and Primary Care in the State of Vermont

Introduction: Recent increase in measles cases has sparked vaccination controversy. Naturopathic physicians (NDs) have been recognized as primary care providers by VT since 2012. It is not well understood how NDs address vaccination with patients. Our goal was to determine how Vermont NDs address vaccines and preventative care with their patients.https://scholarworks.uvm.edu/comphp_gallery/1234/thumbnail.jp

Testosterone Influence on Gene Expression in Lacrimal Glands of Mouse Models of Sjögren Syndrome

Purpose: Sjögren syndrome is an autoimmune disorder that occurs almost exclusively in women and is associated with extensive inflammation in lacrimal tissue, an immune-mediated destruction and/or dysfunction of glandular epithelial cells, and a significant decrease in aqueous tear secretion. We discovered that androgens suppress the inflammation in, and enhance the function of, lacrimal glands in female mouse models (e.g., MRL/MpJ-Tnfrsf6lpr [MRL/lpr]) of Sjögren syndrome. In contrast, others have reported that androgens induce an anomalous immunopathology in lacrimal glands of nonobese diabetic/LtJ (NOD) mice. We tested our hypothesis that these hormone actions reflect unique, strain- and tissue-specific effects, which involve significant changes in the expression of immune-related glandular genes. Methods: Lacrimal glands were obtained from age-matched, adult, female MRL/lpr and NOD mice after treatment with vehicle or testosterone for up to 3 weeks. Tissues were processed for analysis of differentially expressed mRNAs using CodeLink Bioarrays and Affymetrix GeneChips. Data were analyzed with bioinformatics and statistical software. Results: Testosterone significantly influenced the expression of numerous immune-related genes, ontologies, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways in lacrimal glands of MRL/lpr and NOD mice. The nature of this hormone-induced immune response was dependent upon the autoimmune strain, and was not duplicated within lacrimal tissues of nonautoimmune BALB/c mice. The majority of immune-response genes regulated by testosterone were of the inflammatory type. Conclusions: Our findings support our hypothesis and indicate a major role for the lacrimal gland microenvironment in mediating androgen effects on immune gene expression

An experimental and theoretical study of transient negative ions in Mg, Zn, Cd and Hg

A range of experimental and theoretical techniques have been applied to the study of transient negative ions (resonances) formed in electron scattering from the Group II metals Mg, Zn, Cd, and Hg at incident electron energies below the first ionization potential. A wealth of resonance structures have been observed and from the experimental observations and theoretical information, classifications are proposed for some of these negative ion states
