title: Therapists Who Do Not Seek Therapy: An Examination of Marriage and Family Therapists in Three Western States
Creators: name: Wood, Austin
Publisher: name: Utah State University
Year: 2002

description: This was an exploratory study of 243 MFTs in the states of Colorado, Utah, and Wyoming. A majority (66%) reported that they had been in therapy at some time during their careers. The purposes of this research were to (a) find out how therapists effectively and ethically cope with stress, (b) find out more about the therapists who do not utilize therapy, and (c) find out what barriers therapists face in seeking therapy when they do need or desire it.
Effective coping strategies for stress included religious activities, exercise, and spending time with family and friends. Characteristics associated with not having been to therapy were being male, in a first marriage, Latter-day Saint, working in a for-profit agency with inpatient clients, licensed in Utah, and having at least three children. The most common barriers to seeking therapy were "I can handle my own problem(s) effectively enough without therapy" and "My problem(s) is/are not significant enough."

description: First, the solution uniqueness, existence and regularity for stationary anisotropic (linear) Stokes and generalised Oseen systems with constant viscosity coefficients in a compressible framework are analysed in a range of periodic Sobolev (Bessel-potential) spaces on $n$-dimensional flat torus. By the Galerkin algorithm, the linear results are employed to show existence of solution to the stationary anisotropic (non-linear) Navier-Stokes incompressible system on torus in a periodic Sobolev space for any $n\ge 2$. Then the solution uniqueness and regularity results for stationary anisotropic Navier-Stokes system on torus are established for $n\in\{2,3,4\}$.

description: Every $k$-tree has book thickness at most $k+1$, and this bound is best possible for all $k\geq3$. Vandenbussche et al. (2009) proved that every $k$-tree that has a smooth degree-3 tree decomposition with width $k$ has book thickness at most $k$. We prove this result is best possible for $k\geq 4$, by constructing a $k$-tree with book thickness $k+1$ that has a smooth degree-4 tree decomposition with width $k$. This solves an open problem of Vandenbussche et al. (2009)

description: We prove the consistency of the Bäcklund transformation (BT) for the spin Calogero-Moser (sCM) system in the rational, trigonometric, and hyperbolic cases. The BT for the sCM system consists of an overdetermined system of ODEs; to establish our result, we construct and analyze certain functions that measure the departure of this overdetermined system from consistency and show, under mild assumptions, that these functions are identically zero and that this allows for a unique solution to the initial value problem for the overdetermined system.

title: Planning for the Future of Individuals with Developmental Disabilities
Creators: name: Broadbent, Dianna L. Payne
Publisher: name: Utah State University
Year: 2003

description: This descriptive study examined the current status of future planning preparation by caregivers for individuals with developmental disabilities, including mental retardation (DD/MR) in the State of Utah. Other descriptive variables identified areas of planning in which the caregivers required assistance, perceived barriers to future planning, and preferences regarding conveyance of planning information.
Persons with developmental disabilities were identified by the state computer system as either on the waiting list for or currently receiving services through the Division of Services for People with Disabilities. The targeted sample was narrowed to persons with developmental disabilities over the age of 20 years who resided with a caregiver.
Surveys were sent to 1,049 households, and 397 eligible responses (37.8%) were analyzed to find trends in response patterns. Caregivers indicated areas in which plans for the person's future had been established. Elements of planning were found in the areas of guardianship, and future caregiving or residential arrangements.
Most caregivers stated that the components of future planning were overwhelming. They were unsure of the areas in which they needed to plan, unaware of services that were available for the person with DD/MR, and dismayed by the fact that funding for current service needs was unavailable through the state developmental disability agency. Families also denoted emotional barriers to planning for the future.
Respondents were asked to indicate methods of obtaining information they had used previously, which techniques were most helpful in conveying knowledge, and in which manner they would prefer to receive information about planning for the future of the individual with DD/MR. Caregivers indicated a need for planning information presented in a one-on-one setting with a knowledgeable caseworker. They stated the necessity of referrals to financial planners and lawyers familiar with the unique planning needs of persons with DD/MR, as well as the need for financial assistance to pay for costs associated with making formal plans. Findings and implications for assisting caregivers with planning for the future of their family member with developmental disabilities are outlined.
Logarithmic behavior of degradation dynamics in metal--oxide semiconductor devices

Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: In this paper the authors describe a theoretical simple statistical modelling of relaxation process in metal-oxide semiconductor devices that governs its degradation. Basically, starting from an initial state where a given number of traps are occupied, the dynamics of the relaxation process is measured calculating the density of occupied traps and its fluctuations (second moment) as function of time. Our theoretical results show a universal logarithmic law for the density of occupied traps $\bar{} \sim ϕ(T,E_{F}) (A+B \ln t)$, i.e., the degradation is logarithmic and its amplitude depends on the temperature and Fermi Level of device. Our approach reduces the work to the averages determined by simple binomial sums that are corroborated by our Monte Carlo simulations and by experimental results from literature, which bear in mind enlightening elucidations about the physics of degradation of semiconductor devices of our modern life.

description: The review of possible stimulation mechanisms of LENR (low energy nuclear reaction) is represented. We have concluded that transmutation of nuclei at low energies and excess heat are possible in the framework of the modern physical theory -- the universal resonance synchronization principle [1] and based on its different enhancement mechanisms of reaction rates are responsible for these processes [2]. The excitation and ionization of atoms may play role as a trigger for LENR. Superlow energy of external fields may stimulate LENR [3]. Investigation of this phenomenon requires knowledge of different branches of science: nuclear and atomic physics, chemistry and electrochemistry, condensed matter and solid state physics,... The results of this research field can provide a new source of energy, substances and technologies. The puzzle of poor reproducibility of experimental data is due to the fact that LENR occurs in open systems and it is extremely sensitive to parameters of external fields and systems. Classical reproducibility principle should be reconsidered for LENR experiments. Poor reproducibility and unexplained results do not means that the experiment is wrong.

Using ages and kinematic traceback: the origin of young local associations

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Over the last decade, several groups of young (mainly low-mass) stars have been discovered in the solar neighbourhood (closer than ~100 pc), thanks to cross-correlation between X-ray, optical spectroscopy and kinematic data. These young local associations offer insights into the star formation process in low-density environments, shed light on the substellar domain, and could have played an important role in the recent history of the local interstellar medium. Ages estimates for these associations have been derived in the literature by several ways. In this work we have studied the kinematic evolution of young local associations and their relation to other young stellar groups and structures in the local interstellar medium, thus casting new light on recent star formation processes in the solar neighbourhood. We compiled the data published in the literature for young local associations, including the astrometric data from the new Hipparcos reduction. Using a realistic Galactic potential we integrated the orbits for these associations and the Sco-Cen complex back in time. Combining these data with the spatial structure of the Local Bubble and the spiral structure of the Galaxy, we propose a recent history of star formation in the solar neighbourhood. We suggest that both the Sco-Cen complex and young local associations originated as a result of the impact of the inner spiral arm shock wave against a giant molecular cloud. The core of the giant molecular cloud formed the Sco-Cen complex, and some small cloudlets in a halo around the giant molecular cloud formed young local associations several million years later. We also propose a supernova in young local associations a few million years ago as the most likely candidate to have reheated the Local Bubble to its present temperature.

description: In this paper, we describe two complementary non-linear spectroscopy methods which both allow to achieve Doppler-free spectra of atomic gases. First, saturated absorption spectroscopy is used to investigate the structure of the $5{\rm S}_{1/2}\to 5{\rm P}_{3/2}$ transition in rubidium. Using a slightly modified experimental setup, Doppler-free two-photon absorption spectroscopy is then performed on the $5{\rm S}_{1/2}\to 5{\rm D}_{5/2}$ transition in rubidium, leading to accurate measurements of the hyperfine structure of the $5{\rm D}_{5/2}$ energy level. In addition, electric dipole selection rules of the two-photon transition are investigated, first by modifying the polarization of the excitation laser, and then by measuring two-photon absorption spectra when a magnetic field is applied close to the rubidium vapor. All experiments are performed with the same grating-feedback laser diode, providing an opportunity to compare different high resolution spectroscopy methods using a single experimental setup. Such experiments may acquaint students with quantum mechanics selection rules, atomic spectra and Zeeman effect.

The cooperative processes can be induced and enhanced by low energy external fields. The excess heat is the emission of internal energy and transmutations at LENR are the result of redistribution inner energy of whole system.

description: Thin filters and gas tight windows are used in Space to protect sensitive X-ray detectors from out-of-band electromagnetic radiation, low-energy particles, and molecular contamination. Though very thin and made of light materials, filters are not fully transparent to X-rays. For this reason, they ultimately define the detector quantum efficiency at low energies. In this chapter, we initially provide a brief overview of filter materials and specific designs adopted on space experiments with main focus on detectors operating at the focal plane of grazing incidence X-ray telescopes. We then provide a series of inputs driving the design and development of filters for high-energy astrophysics space missions. We begin with the identification of the main functional goals and requirements driving the preliminary design, and identify modeling tools and experimental characterization techniques needed to prove the technology and consolidate the design. Finally, we describe the calibration activities required to derive the filter response with high accuracy.We conclude with some hints on materials and technologies presently under investigation for future X-ray missions.

description: We present a simple theoretical framework to describe the thermal noise of a microscopic mechanical beam in a viscous fluid: we use the Sader approach to describe the effect of the surrounding fluid (added mass and viscous drag), and the fluctuation dissipation theorem for each flexural modes of the system to derive a general expression for the power spectrum density of fluctuations. This prediction is compared with an experimental measurement on a commercial atomic force microscopy cantilever in a frequency range covering the two first resonances. A very good agreement is found on the whole spectrum, with no adjustable parameters but the thickness of the cantilever.

description: We derive an arbitrary-gauge criterion under which condensed matter within an electromagnetic field may transition to a photon condensed phase. Previous results are recovered by selecting the Coulomb-gauge wherein photon condensation can only occur for a spatially-varying field and can be interpreted as a magnetic instability. We demonstrate the gauge-invariance of our description directly, but since matter and photons are gauge-relative concepts we find more generally that photon condensation can occur within a spatially uniform field, and that the relative extent to which the instability is both magnetic and electric versus purely magnetic depends on the gauge.

Year: 2011

description: The study seeks to trace the historical development of the form, design and content of supplementary information in the annual reports of Canadian public companies for the period 1938 -- 1963. Public companies refer to all companies, other than mining and oil companies, whose shares were listed on any one of the five stock exchanges in Canada as of June 1, 1964. Supplementary information is defined as any information which a company furnishes in its annual reports other than the information required to be published by the Companies Act, Canada. Specifically, the study is based on an analysis of the annual reports of 115 Canadian public companies for five selected years, namely: 1938, 1948, 1953, 1958, 1963. The 115 companies were picked by means of stratified random sampling. They represent approximately 19% of the total listed public companies. Among the main findings of the study, three trends were particularly outstanding, namely: the trend toward more disclosure .of supplementary information, the trend toward improved format and design in the presentation of supplementary information and the trend toward an enlarged report.
Time to fixation in the presence of recombination

description: We study the evolutionary dynamics of a haploid population of infinite size recombining with a probability $r$ in a two locus model. Starting from a low fitness locus, the population is evolved under mutation, selection and recombination until a finite fraction of the population reaches the fittest locus. An analytical method is developed to calculate the fixation time $T$ to the fittest locus for various choices of epistasis. We find that (1) for negative epistasis, $T$ decreases slowly for small $r$ but decays fast at larger $r$ (2) for positive epistasis, $T$ increases linearly for small $r$ and mildly for large $r$ (3) for compensatory mutation, $T$ diverges as a power law with logarithmic corrections as the recombination fraction approaches a critical value. Our calculations are seen to be in good agreement with the exact numerical results.

description: Theoretically predicted yields of elements created by the rapid neutron capture (r-) process carry potentially large uncertainties associated with incomplete knowledge of nuclear properties and approximative hydrodynamical modelling of the matter ejection processes. We present an in-depth study of the nuclear uncertainties by varying theoretical nuclear input models that describe the experimentally unknown neutron-rich nuclei. This includes two frameworks for calculating the radiative neutron capture rates and 14 different models for nuclear masses, $β$-decay rates and fission properties. Our r-process nuclear network calculations are based on detailed hydrodynamical simulations of dynamically ejected material from NS-NS or NS-BH binary mergers plus the secular ejecta from BH-torus systems. The impact of nuclear uncertainties on the r-process abundance distribution and the early radioactive heating rate is found to be modest (within a factor of $\sim20$ for individual $A>90$ abundances and a factor of 2 for the heating rate). However, the impact on the late-time heating rate is more significant and depends strongly on the contribution from fission. We witness significantly larger sensitivity to the nuclear physics input if only a single trajectory is used compared to considering ensembles of $\sim$200-300 trajectories, and the quantitative effects of the nuclear uncertainties strongly depend on the adopted conditions for the individual trajectory. We use the predicted Th/U ratio to estimate the cosmochronometric age of six metal-poor stars and find the impact of the nuclear uncertainties to be up to 2 Gyr.

description: We consider the production of axion dark matter through the misalignment mechanism in the context of a nonstandard cosmological history involving early matter domination by a scalar field with a time-dependent decay rate. In cases where the temperature of the Universe experiences a temporary period of increase, Hubble friction can be restored in the evolution of the axion field, resulting in the possibility of up to three "crossings" of the axion mass and the Hubble expansion rate. This has the effect of dynamically resetting the misalignment mechanism to a new initial state for a second distinct phase of oscillation. The resultant axion mass required for the present dark matter relic density is never bigger than the standard-history window and can be smaller by more than three orders of magnitude, which can be probed by upcoming experiments such as ABRACADABRA, KLASH, ADMX, MADMAX, and ORGAN, targeting the axion-photon coupling. This highlights the possibility of exploring the cosmological history prior to Big Bang Nucleosynthesis through searches for axion dark matter beyond the standard window.

description: We determine the energy of an interface between a multiband superconducting and a normal half-space, in presence of an applied magnetic field, based on a multiband Ginzburg-Landau (GL) approach. We obtain that the multiband surface energy is fully determined by the critical temperature, electronic densities of states, and superconducting gap functions associated with the different band condensates. This furthermore yields an expression for the thermodynamic critical magnetic field, in presence of an arbitrary number of contributing bands. Subsequently, we investigate the sign of the surface energy as a function of material parameters, through numerical solution of the GL equations. Here, we consider two distinct cases: (i) standard multiband superconductors with attractive interactions, and (ii) a three-band superconductor with a chiral ground state with phase frustration, arising from repulsive interband interactions. Furthermore, we apply this approach to several prime examples of multiband superconductors, such as metallic hydrogen and MgB$_2$, based on microscopic parameters obtained from first-principles calculations.
title: The Self-Perceived Need for Parent Education by Divorced Parents
Creators: name: Hunsaker, T. Wayne
Publisher: name: Utah State University
Year: 1987

description: The purpose of this study was to determine the self perceived needs of divorced parents for parent education. Five independent variables, age, sex, income level, education, and time since divorce were analyzed. The survey was organized into three major parts with sub-headings. The survey questions asked divorced parents what parent education resources they used before, after divorce, and use now or in the future. Other questions asked what content these resources should contain. The survey was completed in Houston Texas, and Ogden, Utah with a total N of 38.
The results of the analysis indicated there was no significant differences in the perceived effectiveness of the existing parent education resources, nor the perceived need for additional resources in either child development or personal growth, based on the age, sex, income level, educational attainment, or time since divorce of a sample of divorced parent responses.
Writers of curriculum for divorced parents however should note the high degree of unanimity among divorced parents on many content areas, and the information resources used.

description: A stock market speculation scheme proposed by Sidney S. Alexander was tested and was found to be more profitable than would be predicted on the assumption that stock prices perform a random walk with a Gaussian distribution and linear trend. The difference between empirical and theoretical gains was found to be statistically significant. By means of an F-ratio, it was demonstrated that the statistical estimate of the variance of the population of price fluctuations tends to increase as the size of sample is increased. This is consistent with the assumption that the population actually has an infinite variance, but is not consistent with the behavior which would be predicted by any variety of Gaussian random walk. The sophisticated quantity theory of money was found to be unable to account for any non-random movements in stock market price indices.
title: Food Practices and Ritual in the Family Across Three Generations
Creators: name: Liddil, Audrey Crawford
Publisher: name: Utah State University
Year: 1987

description: The overall purpose of this study was to assess family patterns in regard to food practices and family rituals that occur in all families. Specifically, four major purposes were considered in this study: (a) to learn more about generational food practices and how they are passed from one generation to the next, (b) to analyze demographic factors in relation to food related practices, (c) to understand the role of family ritual in family food practices, and (d) to learn how family food practices impact the dietary patterns for society at large.
The data were obtained in February am March of 1986 from Idaho state University students via an 11-page questionnaire. The sample included 20 Young married couples with a child at least two years of age and both sets of their parents. Information was gathered from the grandparent generation by asking questions of the parent generation considering their home of origin.
The major findings of this study were:
1. Parental example was the largest factor in food habits, with mothers having the greatest impact between the parents. When considering special eating styles and settings, mothers were more likely to pass information across generations than fathers. Mothers have been, and are still, the major menu planners and meal preparers; but fathers I influence on food habits has increased over time, especially when considering what is served to the family. Mothers desire more fixed meal scheduling than fathers or other family members.
2. The average time spent at meals has decreased over time, and saying grace at meals has increased across time.
3. The second generation was the most influential generation in celebrating holidays with special eating styles and patterns.
4. Televisions and microwave ovens are having a major impact on families over time. With increased ownership of microwaves, there is an increase of snacking instead of having regular meals. Television viewing at meal time has increased dramatically over time. A major implication of this study is to provide food and nutrition educational programs that teach all family members the central concepts that can be applied in the changing daily eating practices.

description: Kalb-Ramond equations for massive and massless particles are considered in the framework of the Petiau-Duffin-Kemmer formalism. We obtain $10\times10$ matrices of the relativistic wave equation of the first-order and solutions in the form of density matrix. The canonical and Belinfante energy-momentum tensors are found. We investigate the scale invariance and obtain the conserved dilatation current. It was demonstrated that the conformal symmetry is broken even for massless fields.

title: A Follow-Up Study of Utah State Agricultural College Graduates in 1948, 1951, and 1954, Who Obtained Secondary Teaching Certificates
Creators: name: Low, Wendell Blair
Publisher: name: Utah State University
Year: 1956

description: Many educators consider the shortage of qualified teaching personnel as one of the most serious problems in education. In the past this shortage has been primarily confined to the elementary level. However, the United States Department of Education states: Long-run forecasts of population indicate that employment of secondary teachers should be higher throughout the forty-year period 1960-2000 than in 1950. The long-range trend for a rising proportion of young people to attend high school is expected to continue. Greatly increased Federal and State aid to education might expand enrollments considerably. The trend toward enriching curriculum, offering special subjects, and extending instruction to adult classes may also further increase the demand for secondary school teachers.
Formation of relativistic MHD jets: stationary state solutions & numerical simulations
Creators: name: Fendt, Christian

description: We discuss numerical results of relativistic magnetohydrodynamic (MHD) jet formation models. We first review some examples of stationary state solutions treating the collimation and acceleration process of relativistic MHD jets. We provide an a posteriori check for the MHD condition in highly magnetized flows, namely the comparison of particle density to Goldreich-Julian density. Using the jet dynamical parameters calculated from the MHD model we show the rest-frame thermal X-ray spectra of the jet, from which we derive the overall spectrum taking into account a variation of Doppler boosting and Doppler shift of emission lines along the outflow. Finally, we present preliminary results of relativistic MHD simulations of jet formation demonstrating the acceleration of a low velocity (0.01c) disk wind to a collimated high velocity (0.8c).

title: Long-Term Effectiveness of Educational Intervention on the Assertiveness, Self-Esteem, and Well-Being of Displaced Homemakers
Creators: name: Mathias, Marc F.
Publisher: name: Utah State University
Year: 1987

description: The purpose of this study was to determine if educational intervention could cause a decrease in distress, and if so would this change last up to a year. The sample consisted of displaced homemakers from three Northern Utah counties enrolled in a seminar (educational intervention) to prepare for the development of employment skills. Pre-test, post-test and follow-up tests were given to measure the change in stress. The three measures used to determine the psychological preparation (a reduction in distress level) were assertiveness, self-esteem and well-being. It was concluded that the educational intervention did reduce the distress level and that the change did last over a period of one year. The only exception was in the case of low-Income displaced homemakers.

description: We present a numerical study of turbulence in Bose-Einstein condensates within the 3D Gross-Pitaevskii equation. We concentrate on the direct energy cascade in forced-dissipated systems. We show that behavior of the system is very sensitive to the properties of the model at the scales greater than the forcing scale, and we identify three different universal regimes: (1) a non-stationary regime with condensation and transition from a four-wave to a three-wave interaction process when the largest scales are not dissipated, (2) a steady weak wave turbulence regime when largest scales are dissipated with a friction-type dissipation, (3) a state with a scale-by-scale balance of the linear and the nonlinear timescales when the large-scale dissipation is a hypo-viscosity.

description: We predict robust Ising ferromagnetism driven by Coulomb interaction in the metallic phase of twisted transition metal dichalcogenides homobilayers for a range of small twist angles. Due to the presence of spin-valley locking and Chern band, the completely spin polarized state -- a half metal -- has a spin gap and exhibits anomalous Hall effect. We also find that near a magic angle where the Chern band is predicted to be exceptionally flat, the anomalous Hall metal at $1/3$ filling may become unstable at low temperature to a $\sqrt{3}\times\sqrt{3}$ charge density wave, or a fractional Chern insulator.
title: Parent-Adolescent Sexual Attitude Congruence in Relation to Adolescent Sexual Intercourse Experience
Creators: name: McCoy, John Kelly
Publisher: name: Utah State University
Year: 1987

description: Survey data from 472 adolescents (ages 14-19) and their parents were analyzed to examine the relationship that existed between the premarital sexual attitudes of parents and the sexual behavior of their adolescents. The attitudes of the adolescents and their parents were measured using Likert type questions about sexual Intercourse prior to marriage. The sexual behavior of adolescents was based on the responses of the adolescents regarding their frequency of necking, petting, and sexual Intercourse. The relationship between adolescents' sexual behavior and parents' attitudes was examined using several different conceptual models. The amount of attitude agreement that mothers and fathers had with one another - as well as with their adolescent - was significant to understanding the contribution parents had on adolescents' sexual behavior. The direction of parent-adolescent attitude agreement and husband-wife attitude agreement was also found Important In understanding how congruence functioned.

description: Motivated by Hall viscosity measurements in graphene sheets, we study hydrodynamic transport of electrons in a channel of finite width in external electric and magnetic fields. We consider electric charge densities varying from close to the Dirac point up to the Fermi liquid regime. We find two competing contributions to the hydrodynamic Hall and inverse Nernst signals that originate from the Hall viscous and Lorentz forces. This competition leads to a non-linear dependence of the full signals on the magnetic field and even a cancellation at different critical field values for both signals. In particular, the hydrodynamic inverse Nernst signal in the Fermi liquid regime is dominated by the Hall viscous contribution. We further show that a finite channel width leads to a suppression of the Lorenz ratio, while the magnetic field enhances this ratio. All of these effects are predicted in parameter regimes accessible in experiments.
