Parent Interaction Between an Infant with a Cochlear Implant and Additional Disabilities
Pediatric hearing loss has many spoken language learning issues that can impact parent-infant interaction. Moreover, additional disabilities are likely to increase stress, which could have cascading effects on communication. The purpose of the study was to examine interactions between mother- and father-child dyads with and without hearing loss and/or Autism Spectrum Disorder (ASD), Cytomegalovirus (CMV), and global delay. Recordings of the parents speaking with six infants in the study were analyzed: an infant with cochlear implants and ASD (low socioeconomic status, SES), two infants with cochlear implants and normal development (high SES and low SES), one infant with a cochlear implant and CMV (average SES), one infant with a cochlear implant and global delay (average SES), and one infant who was typically developing and had normal hearing (high SES). After analyzing the results for communication measures, such as vocalization attempts, turn-taking in utterances, mean-length of utterances, and type-token ratio, it was concluded that maternal and paternal interaction was negatively affected due not only to the difficulty of the hearing loss and/or additional disability, but rather due to a combination of factors, including the disability, SES, maternal and paternal education, and the home environment
Compact elliptical basis functions for surface reconstruction
In this technical report I present a method to reconstruct a surface representation from a a set of EBF's, and in addition present an efficient top--down method to build an EBF representation from a point cloud representation of a surface. I also discuss the advantages and disadvantages of this approach
Chiral mixed phase in disordered 3d Heisenberg models
Using Monte Carlo simulations, we compute the spin stiffness of a site-random
3d Heisenberg model with competing ferromagnetic and antiferromagnetic
interactions. Our results for the pure limit yield values of the the critical
temperature and the critical exponent in excellent agreement with
previous high precision studies. In the disordered case, a mixed "chiral" phase
is found which may be in the same universality class as 3d Heisenberg spin
glasses.Comment: 5 pages, 4 figures, accepted in PRB Rapid Communication
Universality in short-range Ising spin glasses
The role of the distribution of coupling constants on the critical exponents
of the short-range Ising spin-glass model is investigated via real space
renormalization group. A saddle-point spin glass critical point characterized
by a fixed-point distribution is found in an appropriated parameter space. The
critical exponents and are directly estimated from the data of
the local Edwards-Anderson order parameters for the model defined on a diamond
hierarchical lattice of fractal dimension . Four distinct initial
distributions of coupling constants (Gaussian, bimodal, uniform and
exponential) are considered; the results clearly indicate a universal behavior.Comment: 11 pages, 4 figures, to published in Physica A 199
2012 Oregon Vineyard and Winery Census Report
This statewide survey report on vineyards and wineries in Oregon covers bearing and nonbearing acres, size of vineyard operation, variety and county, size distribution, prices, yields, crush, inventory, and sales. The report also contains some comparisons of data sor 2011 and 2012. According to this report, continued growth was seen in nearly all aspects of the industry
Real Space Renormalization Group Theory of Disordered Models of Glasses
We develop a real space renormalisation group analysis of disordered models
of glasses, in particular of the spin models at the origin of the Random First
Order Transition theory. We find three fixed points respectively associated to
the liquid state, to the critical behavior and to the glass state. The latter
two are zero-temperature ones; this provides a natural explanation of the
growth of effective activation energy scale and the concomitant huge increase
of relaxation time approaching the glass transition. The lower critical
dimension depends on the nature of the interacting degrees of freedom and is
higher than three for all models. This does not prevent three dimensional
systems from being glassy. Indeed, we find that their renormalisation group
flow is affected by the fixed points existing in higher dimension and in
consequence is non-trivial. Within our theoretical framework the glass
transition results to be an avoided phase transition.Comment: 6 pages, 3 figure
