Parent and Teacher Report: Comparing Results from the Sensory Profile and the Sensory Profile School Companion

OBJECTIVE. This study investigated the similarities and differences between parent and teacher report on the Sensory Profile and the Sensory Profile School Companion (School Companion). METHOD. Using data gathered during the standardization of the School Companion, scores of 173 children with and without disabilities were analyzed. Results were based on the entire sample and subgroups organized by child, parent, and teacher demographics. RESULTS. Analyses of the entire sample demonstrate that parents and teachers have many significant similarities (16/18) and few significant differences (2/18). Scoring relationships between reporters for subgroups followed the pattern found in the literature for other parent/teacher questionnaires. CONCLUSION. Parents and teachers provided a combination of similar and unique information when evaluating a child using the Sensory Profile and the School Companion thus adding to their construct validity. Therefore, best practice indicates that evaluators should interpret results from both versions when evaluating children with these tools

Structural Dependence of the Molecular Mobility in the Amorphous Fractions of Polylactide

Fragility index and cooperativity length characterizing the molecular mobility in the amorphous phase are for the first time calculated in drawn polylactide (PLA). The microstructure of the samples is investigated from wide-angle X-ray scattering (WAXS) whereas the amorphous phase dynamics are revealed from broadband dielectric spectroscopy (BDS) and temperature-modulated differential scanning calorimetry (TMDSC). The drawing processes induce the decrease of both cooperativity and fragility with the orientation of the macromolecules. Post-drawing annealing reveals an unusual absence of correlation between the evolutions of cooperativity length and fragility. The cooperativity length remains the same compared to the drawn sample while a huge increase of the fragility index is recorded. By splitting the fragility index in a volume contribution and an energetic contribution, it is revealed that the amorphous phase in annealed samples exhibits a high energetic parameter, even exceeding the amorphous matrix value. It is assumed that the relaxation process is driven in such a way that the volume hindrance caused by the thermomechanical constraint is compensated by the acceleration of segmental motions linked to the increase of degrees of freedom. This result should also contribute to the understanding of the constraint slackening in the amorphous phase during annealing of drawn PLA, which causes among others the decrease of its barrier properties

A General Introduction to Integral Theory and Comprehensive Mapmaking

While attempting to keep to the larger vision of integral studies as a whole I shall be proposing a rudimentary outline of an underlying assertion primarily based upon the works of Ken Wilber, Jean Gebser, Don Beck and Christopher Cowan (based on the work of Clare Graves), and Mark B. Woodhouse. Robert Kegan, Howard Gardner, James Mark Baldwin, Susan Cook-Greuter, and Carol Gilligan are influences working in the background. Perhaps the most important thing to keep in mind when trying to understand integral studies as a field is that a fundamental, underlying message in Wilber\u27s, Graves\u27, Beck\u27s, Gebser\u27s, and Woodhouse\u27s work is that we are currently in a pivotal transition from one age to another. The idea, and this is a rather popular idea, is that we are in the throes of a rather deep and penetrating shift in collective consciousness complete with its own once-in-a-lifetime phenomena. In my humble opinion, the works exemplified in this essay are among the most sophisticated, timely, and comprehensive manifestations of this general perception of global transformation. The main function of this essay is to serve as a preliminary introduction to the new field of integral studies by looking into four particular theorists. Three of these, Wilber, Beck, and Gebser, are highly influential and central to the field. This has much to do with Wilber\u27s highly influential work. Woodhouse, on the other hand, exemplifies an outsider perspective yet remains, I believe just as inclusive. This is an argument for the validity of the integral approach and a call to awareness about the transition that is represents. By proposing a context for the field within the boundaries of the common underlying message of a profound shift in human consciousness, we can come to a greater comprehension of what can be considered to be among the most refined manifestations of human potential to date

Glass transition investigated by a combined protocol using thermostimulated depolarization currents and differential scanning calorimetry

Relaxation times of bisphenol A polycarbonate around the glass transition temperature are estimated using the combination of differential scanning calorimetry (DSC) and thermostimulated depolarization currents (TSDC). These measurements are performed using samples with different thermal histories below and above the vitrification transformation. This protocol enables the extension of the range of equilibrium relaxation times measured by dielectric spectroscopy. By this mean we may recalculate the values of the Kauzmann temperature and fragility index

Fragility of a thermoplastic polymer. Influence of main chain rigidity in polycarbonate

We present new data on a vitreous polycarbonate (PC) and its fragility index. Measurements have been performed by means of differential scanning calorimetry (DSC). A comparison with other data already published in this field and concerning other linear polymers is made. We show that when experiments are performed by means of DSC, the use of the glass-forming liquid fragility concept does not lead to large enough variations of the fragility index values. Thus, any correlation with structural characteristics of linear polymers, is not possible, except in the case of main chain rigidity

Study of poly(bisphenol A carbonate) relaxation kinetics at the glass transition temperature

In this work, the variations of the relaxation times are investigated above and below the glass transition temperature of a model amorphous polymer, the polycarbonate. Three different techniques (calorimetric, dielectric and thermostimulated currents) are used to achieve this goal. The relaxation time at the glass transition temperature was determined at the temperature dependence convergence of the relaxation times calculated with dynamic dielectric spectroscopy (DDS) for the liquid state and thermostimulated depolarisation currents (TSDC) for the vitreous state. We find a value of s(Tg) = 110 s for PC samples. The knowledge of the temperature dependence, s(T), and the value s(Tg) enables to determine the glass-forming liquid fragility index, m. We find m = 178 ± 5

From Monomers to Self-Assembled Monolayers: The Evolution of Molecular Mobility with Structural Confinements

The effect of structural constriction on molecular mobility is investigated by broadband dielectric spectroscopy (BDS) within three types of molecular arrangements: monomers, oligomers and self-assembled monolayers (SAMs). While disordered monomers exhibit a variety of cooperative and local relaxation processes, the constrained nanodomains of oligomers and highly ordered structure of monolayers exhibit much hindered local molecular fluctuations. Particularly, in SAMs, motions of the silane headgroups are totally prevented whereas the polar endgroups forming the monolayer canopy show only one cooperative relaxation process. This latter molecular fluctuation is, for the first time, observed independently from other overlapping dielectric signals. Numerous electrostatic interactions among those dipolar endgroups are responsible for the strong cooperativity and heterogeneity of the canopy relaxation process. Our data analyses also revealed that the bulkiness of dipolar endgroups can disrupt the organization of the monolayer canopy thus increasing their ability to fluctuate as temperature is increased

O Originário da Arte em Martin Heidegger

Procurar por um originário da obra arte, por algo que permeie toda a arte, é uma busca pela essência da arte, porém, como nos alerta Martin Heidegger em sua conferência sobre o tema, a essência não é algo estático e petrificado, mas aquilo que existe em vigor na própria obra. O caminho empreendido pelo pensador alemão parte das maneiras mais tradicionais em que a arte é pensada, para chegar, a partir dessas mesmas maneiras, a uma nova possibilidade de compreensão de onde promana a verdadeira origem da arte

Interfacial Characterization by Pull-Out Test of Bamboo Fibers Embedded in Poly(Lactic Acid)

In this work, the apparent shear strength at the interface between a bamboo fiber and the surrounding poly(lactic acid) (PLA) matrix is quantified. A method for processing pull-out test samples within a controlled embedded length is proposed and the details of the test procedure are presented, along with a critical discussion of the results. Two series of samples are considered: untreated and mercerized bamboo fibers from the same batch, embedded in the same polyester matrix. Electron and optical microscopy are used to observe the fiber–matrix interface before and after the test, and to identify the failure mode of each sample, especially as regards the occurrence of fibrillation in the fiber bundles. The values of apparent interfacial shear strength are calculated only for regular fibers successfully pulled out from the matrix, and reported with their statistical variations. Mercerization, whose efficiency was proven by Fourier transform infrared (FTIR) spectroscopy, did not appear though to improve the quality of the interface (Tapp = 7.0 ± 3.1 MPa for untreated fibers and Tapp = 5.3 ± 2.4 MPa for treated fibers)
