From John Lee to John Gottman: Recognizing Intra- and Interpersonal Differences to Promote Marital Satisfaction
Since Extension agents work with a variety of families, there is a desperate need to further our understanding of how to educate diverse communities on a familyrelated topic. Focused on assisting those teaching marital education to a diverse population, this study attempts to understand how individual differences impact relationship satisfaction and marital communication. Based on John Gottman’s research on marital communication and John Lee’s six love styles, 653 participants completed a survey to further understanding of the relationship between inter- and intrapersonal variables. Results revealed that marital communication and love styles accounted for 54.6% of the variance in marital satisfaction regardless of difference in demographics. Results of this study provide a resource for educators and practitioners to use with diverse clientele, while also emphasizing the need to understand both intra- and interpersonal variables when working with families
Numerical studies of planar closed random walks
Lattice numerical simulations for planar closed random walks and their
winding sectors are presented. The frontiers of the random walks and of their
winding sectors have a Hausdorff dimension . However, when properly
defined by taking into account the inner 0-winding sectors, the frontiers of
the random walks have a Hausdorff dimension .Comment: 15 pages, 15 figure
A Class of Stationary Electromagnetic Vacuum Fields
This is the published version, also available here: http://dx.doi.org/10.1063/1.1666066.It is shown how a new class of stationary electromagnetic vacuum fields can be generated from solutions of Laplace's equation. These fields are a stationary generalization of the static electromagnetic vacuum fields of Weyl, Majumdar, and Papapetrou, and are plausibly interpreted as exterior fields of static or steadily moving distributions of charged dust having numerically equal charge and mass densities
New Maser Emission from Nonmetastable Ammonia in NGC 7538. II. Green Bank Telescope Observations Including Water Masers
We present new maser emission from ^{14}NH_3 (9,6) in NGC 7538. Our
observations include the known spectral features near v_LSR = -60 km/s and -57
km/s and several more features extending to -46 km/s. In three epochs of
observation spanning two months we do not detect any variability in the ammonia
masers, in contrast to the >10-fold variability observed in other ^{14}NH_3
(9,6) masers in the Galaxy over comparable timescales. We also present
observations of water masers in all three epochs for which emission is observed
over the velocity range -105 km/s < v_LSR < -4 km/s, including the highest
velocity water emission yet observed from NGC 7538. Of the remarkable number of
maser species in IRS 1, H_2O and, now, ^{14}NH_3 are the only masers known to
exhibit emission outside of the velocity range -62 km/s < v_LSR < -51 km/s.
However, we find no significant intensity or velocity correlations between the
water emission and ammonia emission. We also present a non-detection in the
most sensitive search to date toward any source for emission from the CC^{32}S
and CC^{34}S molecules, indicating an age greater than \approx 10^4 yr for IRS
1-3. We discuss these findings in the context of embedded stellar cores and
recent models of the region.Comment: 7 pages, 4 figures, 3 tables; accepted to AJ; color figures only on

From Research to Practice: Increasing Ability of Practitioners to Relate Family-of-Origin Communicative Techniques to Current Marital Satisfaction
Research has shown a connection between family-of-origin communicative techniques and later marital satisfaction. However, little has been done to see how this information can be incorporated in family life education settings. The purpose of this study is to make a connection between research and practice by testing the validity of easy-to-use measurements informing this relationship. The results of a survey from 649 married individuals about the communicative practices within their family-of-origin and in their current marriage support the ability of practitioners to understand techniques utilized in marriage by interpreting those used in childhood. By associating the literature between family-of-origin communication and marital dynamics in a practical way, practitioners and educators will be better able to assess and assist married couples in therapeutic or educational settings
Synthesizing population, health, and place
This report on the Vespucci Institute on health geography in 2013 emphasizes the importance of research that connects population, health, and place from a holistic perspective. We review important trends related to Health GIS and highlight directions for future research in this area that were identified at the Institute
Efimov physics in a finite volume
Three bosons with large scattering length show universal properties that do
not depend on the details of the interaction at short distances. In the
three-boson system, these properties include a geometric spectrum of shallow
three-body states called "Efimov states" and log-periodic dependence of
scattering observables on the scattering length. We investigate the
modification of the Efimov states in a finite cubic box and calculate the
dependence of their energies on the box size using effective field theory. We
explicitly verify the renormalization of the effective field theory in the
finite volume.Comment: 9 pages, 3 figures, sign error corrected, numerical results changed,

The aerosol-climate model ECHAM5-HAM
The aerosol-climate modelling system ECHAM5-HAM is introduced. It is based on a flexible microphysical approach and, as the number of externally imposed parameters is minimised, allows the application in a wide range of climate regimes. ECHAM5-HAM predicts the evolution of an ensemble of microphysically interacting internally- and externally-mixed aerosol populations as well as their size-distribution and composition. The size-distribution is represented by a superposition of log-normal modes. In the current setup, the major global aerosol compounds sulfate (SU), black carbon (BC), particulate organic matter (POM), sea salt (SS), and mineral dust (DU) are included. The simulated global annual mean aerosol burdens (lifetimes) for the year 2000 are for SU: 0.80 Tg(S) (3.9 days), for BC: 0.11 Tg (5.4 days), for POM: 0.99 Tg (5.4 days), for SS: 10.5 Tg (0.8 days), and for DU: 8.28 Tg (4.6 days). An extensive evaluation with in-situ and remote sensing measurements underscores that the model results are generally in good agreement with observations of the global aerosol system. The simulated global annual mean aerosol optical depth (AOD) is with 0.14 in excellent agreement with an estimate derived from AERONET measurements (0.14) and a composite derived from MODIS-MISR satellite retrievals (0.16). Regionally, the deviations are not negligible. However, the main patterns of AOD attributable to anthropogenic activity are reproduced
