A Rare Family: Exploring Genetic Literacy in an Online Support Group
Healthy People 2020 and the Institute of Medicine (IOM) define health literacy as the âdegree to which individuals have the capacity to obtain, process and understand basic health information and services needed to make appropriate health decisions.â Essential components of health literacy include oral and print literacy, numeracy, and cultural and conceptual knowledge; the latter is influenced by sociodemographic factors and cultural understandings and approaches to concepts such as healthcare. Genetic literacy, a form of health literacy, may be defined as the knowledge, skills and attitudes necessary to individual understanding of genetic information, and genetic-based health, behavior, technology and services, making it a vital component of sexual and reproductive decision-making. The current qualitative research study employed holistic-content and narrative analysis of secondary data (electronic or e-mail posts) from an online support group for individuals affected by a genetic disorder in order to to gain additional insights into specific psychosocial and environmental variables that affect individual genetic literacy, related perceptions of genetic risk, and sexual and reproductive decision-making. Findings from the study indicate that online health-related support groups can evolve into a socially-constructed âfamilyâ of individuals affected by specific disorders. Within this online family, members find others who can identify with their feelings and experiences. Like biological families of origin, this âfamilialâ context may then exert particularly strong influences on membersâ social and health decision-making via co-constructed cultural and conceptual knowledge of the disorder. Further qualitative research needs to be performed to understand the positive and negative impact that participation in a collective consciousness might have on individual genetic literacy necessary for making sensitive decisions such as those involved in sexual and reproductive health. Implications for education and counseling are discussed
Solitonic spin-liquid state due to the violation of the Lifshitz condition in FeTe
A combination of phenomenological analysis and M\"ossbauer spectroscopy
experiments on the tetragonal FeTe system indicates that the magnetic
ordering transition in compounds with higher Fe-excess, 0.11, is
unconventional. Experimentally, a liquid-like magnetic precursor with
quasi-static spin-order is found from significantly broadened M\"ossbauer
spectra at temperatures above the antiferromagnetic transition. The
incommensurate spin-density wave (SDW) order in FeTe is described by a
magnetic free energy that violates the weak Lifshitz condition in the Landau
theory of second-order transitions. The presence of multiple Lifshitz
invariants provides the mechanism to create multidimensional, twisted, and
modulated solitonic phases.Comment: 5 pages, 2 figure
Developing Professional Identity and Networks at Conferences
Professional conferences play an important role in the development of health behavior researchers. These venues are essential for applying academic coursework and advancing or strengthening skills in professional settings. Attending meetings enables students and early career scholars to interact with researchers and practitioners in the field for the purposes of sharing research findings, discussing practice strategies, and exploring career options through networking opportunities. Conference experiences can be enhanced by proper planning and execution before, during, and after the event. This editorial provides recommendations to junior conference attendees related to a variety of topics including time management, presentation etiquette, networking, locating mentors, and post-meeting follow-up procedures
Ferromagnetism and superconductivity in P-doped CeFeAsO
We report on superconductivity in CeFeAs1-xPxO and the possible coexistence
with Ce- ferromagnetism (FM) in a small homogeneity range around x = 30% with
ordering temperatures of T_SC = T_C = 4K. The antiferromagnetic (AFM) ordering
temperature of Fe at this critical concentration is suppressed to T^N_Fe ~ 40K
and does not shift to lower temperatures with further increase of the P
concentration. Therefore, a quantum-critical-point scenario with T^N_Fe -> 0K
which is widely discussed for the iron based superconductors can be excluded
for this alloy series. Surprisingly, thermal expansion and X-ray powder
diffraction indicate the absence of an orthorhombic distortion despite clear
evidence for short range AFM Fe-ordering from muon-spin-rotation measurements.
Furthermore, we discovered the formation of a sharp electron spin resonance
signal unambiguously connected with the emergence of FM ordering.Comment: 5 pages, 4 figures, published in Phys. Rev. B (Rapid Communication,

Modeling NAPL dissolution from pendular rings in idealized porous media
The dissolution rate of nonaqueous phase liquid (NAPL) often governs the remediation time frame at subsurface hazardous waste sites. Most formulations for estimating this rate are empirical and assume that the NAPL is the nonwetting fluid. However, field evidence suggests that some waste sites might be organic wet. Thus, formulations that assume the NAPL is nonwetting may be inappropriate for estimating the rates of NAPL dissolution. An exact solution to the YoungâLaplace equation, assuming NAPL resides as pendular rings around the contact points of porous media idealized as spherical particles in a hexagonal close packing arrangement, is presented in this work to provide a theoretical prediction for NAPLâwater interfacial area. This analytic expression for interfacial area is then coupled with an exact solution to the advectionâdiffusion equation in a capillary tube assuming HagenâPoiseuille flow to provide a theoretical means of calculating the mass transfer rate coefficient for dissolution at the NAPLâwater interface in an organicâwet system. A comparison of the predictions from this theoretical model with predictions from empirically derived formulations from the literature for waterâwet systems showed a consistent range of values for the mass transfer rate coefficient, despite the significant differences in model foundations (water wetting versus NAPL wetting, theoretical versus empirical). This finding implies that, under these system conditions, the important parameter is interfacial area, with a lesser role played by NAPL configuration.Key Points:Exact solution to the YoungâLaplace equation for pendular ringsTheoretical determination of the mass transfer rate coefficient under hydrophobic conditionsPredicts similar NAPL dissolution rates for oilâwet and waterâwet conditionsPeer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/145506/1/wrcr21729.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/145506/2/wrcr21729_am.pd

Real-time earthquake hazard assessment in California; the early post-earthquake damage assessment tool and the Caltech-USGS broadcast of earthquakes
A real-time earthquake monitoring system which provides source parameters
to user groups through a commercial paging service is now in place in California.
A GIS-based system to predict and display near real-time damage and casualty
estimates is currently being developed by EQE International under contract with
the State of California. These new technologies offer immediate tangible benefits
to state and local governments, utilities, lifelines and corporations with facilities
or operations at risk. This paper will outline the development of these new
technologies, identify the contributions they will make to emergency management
and explore some directions these innovative systems may take in the future
