Perceptions and Factors Influencing Success in Professional Preparation Physical Therapy Education
The purpose of this study was to gather data on student background characteristics, the perceptions of social and academic support, and self-concept of current professional preparation physical therapy (PT) students. A second purpose was to determine whether any variables were predictive of academic success/retention and to investigate whether there were differences in those variables between majority and minority PT students. The study used mixed methods with entry-level PT students from Virginia and North Carolina. Questionnaires were collected from 575 of 778 PT students for a 74% response rate. Semi-structured interviews were conducted with 25 respondents. Girves and Wemmerus\u27 conceptual model of doctoral degree progress was used as the theoretical framework for the study. Statistically significant differences were found between ethnic groups in background characteristics, social support, academic support, and all self-concept variables. Overall significant predictors of success were: undergraduate grade point average (GPA), ethnicity, having personal financing sources or loans for school, achieving an award, perceptions that coursework was academically stimulating, perceptions of academic expectations, being satisfied with academic performance, perceived ratings of both undergraduate and graduate performance, and overall rating of their PT school experience. Statistical differences were found between the ethnic groups for predictors of academic success. The interview data supported the quantitative findings and added depth to the findings regarding both similarities and differences between the perceptions of facilitators and barriers experienced by majority and minority PT students. Constructs of the Girves and Wemmerus model were not fully supported for this population of graduate students; however, the combination of variables investigated in this study accounted for 55% of the variance in graduate GPA. The study\u27s findings are utilized in making recommendations for the recruitment and retention of physical therapy students, particularly minority students, in hoping to increase the diversity of the physical therapy profession

Simpulan dari hasil data penelitian ini rata-rata tingkat kecemasan pada kategori “sedang”
Examining the Impact of Treatment Fidelity on Client Outcomes in a Statewide Implementation of Parent-Child Interaction Therapy
Clinician treatment fidelity, consisting of treatment adherence and clinician competence, is commonly assessed during the implementation of evidence-based treatments to ensure that clinicians are delivering care according to an intended service model. Although resources are often expended in fidelity measurement, associations between fidelity and client outcomes has not been well established in the psychotherapy literature. The relationship between clinician fidelity and treatment outcomes was investigated in a longitudinal sample of clinicians (n = 17) and parent-child dyads (n = 32) following a statewide implementation of Parent-Child Interaction Therapy. Observer-rated measures of adherence and coaching competence collected from early treatment sessions were used to predict intake levels and growth trajectories of parent-reported behavior problems and positive parenting skills. Hierarchical linear modeling results indicated that higher levels of coaching competence were associated with greater behavior problem frequency at intake. Neither early session adherence nor early session competence, as they were measured in the current study, predicted changes in treatment outcomes over time. These results suggest that additional variables should be modeled alongside early treatment fidelity to predict treatment outcome change. Possible explanations for these findings, limitations of the current study, and directions for future research are discussed
Emulsion formation and stabilization by biomolecules: the leading role of cellulose
Emulsion stabilization by native cellulose has been mainly hampered because of its insolubility in water. Chemical modification is normally needed to obtain water-soluble cellulose derivatives. These modified celluloses have been widely used for a range of applications by the food, cosmetic, pharmaceutic, paint and construction industries. In most cases, the modified celluloses are used as rheology modifiers (thickeners) or as emulsifying agents. In the last decade, the structural features of cellulose have been revisited, with particular focus on its structural anisotropy (amphiphilicity) and the molecular interactions leading to its resistance to dissolution. The amphiphilic behavior of native cellulose is evidenced by its capacity to adsorb at the interface between oil and aqueous solvent solutions, thus being capable of stabilizing emulsions. In this overview, the fundamentals of emulsion formation and stabilization by biomolecules are briefly revisited before different aspects around the emerging role of cellulose as emulsion stabilizer are addressed in detail. Particular focus is given to systems stabilized by native cellulose, either molecularly-dissolved or not (Pickering-like effect).Financially support by the Portuguese Foundation for Science and Technology, FCT, via the projects PTDC/AGR-TEC/4814/2014, PTDC/ASP-SIL/30619/2017 and researcher grant IF/01005/2014.

Star Formation Histories of Dwarf Spheroidal and Dwarf Elliptical Galaxies in the Local Universe
We present the star formation histories (SFHs) of early-type dwarf galaxies,
dSphs and dEs, in the local universe within z=0.01. The SFHs of early-type
dwarf galaxies are characterized by pre-enriched, metal-poor old stellar
populations, absence of moderately old stars that have ages of a few Gyr. There
are some differences in the SFHs of dSphs and dEs. In particular, dSphs formed
old ( Gyr old) metal-poor stars times more than dEs. The
effects of reionization and feedback from supernova explosions are thought to
be strong enough to remove the gas left, which prevent moderately old stellar
populations in dSphs. In contrast, the ejected gas are not completely removed
from dEs and fall back to ignite burst of star formation at a few Gyr after the
first period of violent bursts of star formation, showing a suppression of star
formation at lookback time Gyr. The second peak of star formation
at lookback time Gyr in dEs produce moderately old stellar
populations. Distinction between dSphs and dEs is useful to examine the SFHS of
the early-type dwarfs since the cumulative SFHs are most closely related to
their morphology. The stellar mass plays an important role in the SFHs of the
early-type dwarfs as a driver of star formation, especially in galaxies with
primordial origin.Comment: 16 pages, 16 figure
Power-law decay in first-order relaxation processes
Starting from a simple definition of stationary regime in first-order
relaxation processes, we obtain that experimental results are to be fitted to a
power-law when approaching the stationary limit. On the basis of this result we
propose a graphical representation that allows the discrimination between
power-law and stretched exponential time decays. Examples of fittings of
magnetic, dielectric and simulated relaxation data support the results.Comment: to appear in Phys. Rev. B; 4 figure
