Telehealth Competency Questionnaire-Consumer: Psychometric Validation of a Client-centered Measure
To effectively access telehealth services, individuals must possess certain competencies; yet, telehealth consumer focused measures are limited. The purpose of this study was to describe the development and validation of the Telehealth Competency Questionnaire â Consumer (TCQ-C). Among a sample of adults with chronic health conditions (n=134), findings showed that the TCQ-C is comprised of one factor that accounts for 66.6% of the variance, and internal consistency of subscales are good (range α = 0.80-0.87) and may be used for clinical or research purposes. The TCQ-C demonstrated moderate concurrent validity with the Telehealth Usability Questionnaire-Usability subscale (r = 0.728, p<.001), and significantly discriminates between adults >65 years and those younger as well as those with and without previous telehealth experience. The TCQ-C is a psychometrically sound instrument to evaluate baseline competencies among telehealth consumers so that education, research, and clinical practices are tailored to increase effective engagement between clients and providers

The rise in subscription skin care services
Subscription skin care services are a rising niche of direct-to-consumer telehealth models. The explosion of such services may be a reflection of the increasing demand by patients to have accessible, affordable dermatological care. These models come with both benefits and risks to patients. A thorough understanding of how subscription skin care services work may benefit dermatologists in addressing patients' questions regarding alternative care options
Comparison of Combustion Efficiency to In-Situ Atmospheric Ammonia Measurements from a Miniature Chemical Ionization Mass Spectrometer in the LA Basin
Atmospheric ammonia (NH3) has been shown to impact the environment and threaten both human and animal health, especially in heavily populated urban areas, yet to date there remains a paucity of direct measurements. Recent studies have suggested that ammonia may be generated as a byproduct of fossil fuel emissions due to highly active catalytic converters in light-duty gasoline vehicles. To investigate this relationship, an airborne miniature Chemical Ionization Mass Spectrometer (miniCIMS) was used to directly measure atmospheric ammonia and combustion reaction products in the Southern California LA Basin, during the 2015 NASA Student Airborne Research Program (SARP). The temporal variability in measured ammonia, and the relationship to combustion efficiency will be compared to mobile ground-based measurements from the NASA DISCOVER-AQ campaign, and implications of the findings will be discussed
Procedures to validate/correct calibration error in solar backscattered ultraviolet instruments
The Nimbus 7 SBUV measures the same latitude ozone at widely different sun angle conditions at the ascent and descent part of the orbit during the summer solstice. This situation is used in a particular procedure (Ascent/Descent) to obtain the relative channel-to-channel calibration error for channels 273 nm to 306 nm. These estimated errors are combined with results from the Pair Justification procedure to correct the sun-view diffuser drift in calibration from November 1978 to February 1987 for the shorter wavelength channels that measure upper stratospheric ozone. Some preliminary re-calirated Nimbus 7 SBUV data in 1989 is compared with the first set of SBUV measurements flown on the Space Shuttle
Topological Entanglement Renyi Entropy and Reduced Density Matrix Structure
We generalize the topological entanglement entropy to a family of topological
Renyi entropies parametrized by a parameter alpha, in an attempt to find new
invariants for distinguishing topologically ordered phases. We show that,
surprisingly, all topological Renyi entropies are the same, independent of
alpha for all non-chiral topological phases. This independence shows that
topologically ordered ground-state wavefunctions have reduced density matrices
with a certain simple structure, and no additional universal information can be
extracted from the entanglement spectrum.Comment: 4 pages, v2: published versio
The Key Events Dose-Response Framework: A Foundation for Examining Variability in Elicitation Thresholds for Food Allergens
Food allergies are caused by immunological reactions in individuals sensitized to normal protein components of foods. For any given sensitized individual, the severity of a reaction is generally assumed to be proportional to the dose of allergenic protein. There is substantial clinical evidence that âthresholdâ doses exist for the elicitation of an allergic reaction; however, the threshold (i.e., lowest dose that elicits a reaction) varies substantially across the sensitized population. Current approaches to protecting sensitized individuals from exposure to food allergens are highly qualitative (i.e., they rely on food avoidance). The Key Events Dose-Response Framework is an analytical approach for refining understanding of the biological basis of the dose-response. Application of this approach to food allergy provides a foundation for a more rigorous quantitative understanding of variability in allergic response. This study reviews the allergic disease process and the current approaches to identifying thresholds for food allergens. The pathway of key biological events occurring between food intake and allergic response is considered, along with factors that may determine the nature and severity of response to food allergens. Data needs, as well as implications for identifying thresholds, and for characterizing variability in thresholds, are also discussed
Cool Companions to White Dwarfs from the 2MASS Second Incremental Data Release
We present near-infrared magnitudes for all white dwarfs (selected from the
catalog of McCook & Sion) contained in the 2 Micron All Sky Survey Second
Incremental Data Release(2MASS 2IDR). We show that the near-IR color-color
diagram is an effective means of identifying candidate binary stars containing
a WD and a low mass main sequence star. The loci of single WDs and WD + red
dwarf binaries occupy distinct regions of the near-IR color-color diagram. We
recovered all known unresolved WD + red dwarf binaries located in the 2IDR sky
coverage, and also identified as many new candidate binaries (47 new candidates
out of 95 total). Using observational near-IR data for WDs and M-L dwarfs, we
have compared a sample of simulated WD + red dwarf binaries with our 2MASS
data. The colors of the simulated binaries are dominated by the low mass
companion through the late-M to early-L spectral types. As the spectral type of
the companion becomes progressively later, however, the colors of unresolved
binaries become progressively bluer. Binaries containing the lowest mass
companions will be difficult to distinguish from single WDs solely on the basis
of their near-IR colors.Comment: 18 pages, including 2 figures, accepted for publication in Ap
