Aesthetic Socialization and the Young Child

An examination of the process of aesthetic socialization at the preschool level reveals communication, through direct and indirect teacher behaviors and classroom environment, of taken for granted aesthetic assumptions. Examples, such as the use of naturalism or realism as the major criterion for judging art and reinforcement of social skills like diligence and neatness through art activities, are examined in light of educationist and teacher contexts. Implications include the need for examination of aesthetic assumptions and their transmission by art educators who work with young children, train teachers, and/or plan art curricula

A survey of structural material issues for a space station

An NASA enters the definition phase of the space station project, one of the important issues to be considered is structural material selection. The complexity of the space station and its long life requirement are two key factors which must be considered in the material selection process. Both aluminum and graphite/epoxy are considered as potential structural materials. Advantages and disadvantages of these materials with respect to mechanical and thermal considerations, space environment, manufacturing, and cost are discussed

The structural behavior of a graphite-polymide honeycomb sandwich panel with quasi-isotropic face sheets and an orthotropic core

The results of a series of tests of graphite-polyimide honeycomb sandwich panels are presented. The panels were 1.22 m long, 0.508 m wide, and approximately 13.3 m thick. The face sheets were a T-300/PMR-15 fabric in a quasi-isotropic layup and were 0.279 mm thick. The core was Hexcel HRH 327-3/16 - 4.0 glass reinforced polyimide honeycomb, 12.7 mm thick. Three panels were used in the test: one was cut into smaller pieces for testing as beam, compression, and shear specimens; a second panel was used for plate bending tests; the third panel was used for in-plane stability tests. Presented are the experimental results of four point bending tests, short block compression tests, core transverse shear modulus, three point bending tests, vibration tests, plate bending tests, and panel stability tests. The results of the first three tests are used to predict the results of some of the other tests. The predictions and experimental results are compared, and the agreement is quite good

Thermal cycling graphite-polyimide

The effects of repetitive thermal cycling on the temperature-thermal deformation relation of graphite-polyimide were determined. The bending and axial strains, measured with strain gages, of unsymmetric 0 deg sub 2/90 deg sub 2 and 0 deg sub 4/90 deg sub 4 laminates were used as an indication of thermal deformation. The strains were measured as a function of temperature and two temperature ranges were used, room temperature to 180 C and room temperature to 315 C. Five cycles were run in each temperature range and the cycling was done in quasistatic fashion. The response of a flat 0 deg sub 8 laminate was measured as were the effects of repetitive cycling on the strain gages themselves. A piece-wise linear theory, based on classical lamination theory and using the variation of mechanical and thermal expansion properties with temperature, was compared with the experimental results. The correlation between theoretical predictions and experimental results for the thinner laminate was poor

Peer Recovery Support Specialists: Role Clarification and Fit Within the Recovery Ecosystems of Central Appalachia

The Peer Recovery Support Specialist (PRSS), a certified professional who self-identifies as being in recovery from a substance use disorder (SUD), mental illness, or co-occurring disorders, plays a key role in the ongoing transformation of SUD treatment from one of acute clinical service provision with documented short-term outcomes including symptom reduction, to a more holistic and comprehensive approach to long-term recovery. Empirical evidence specific to outcomes of PRSS working in the addiction treatment realm is sparse and equivocal, indicating the need for additional research and improved methods designed to explore the nature of the PRSS role and fit within the expanding models of a recovery eco-system. This sequential exploratory mixed-methods study surveyed PRSS in five states of Central Appalachia in order to better understand the nature of their work, personal recovery characteristics and their interactions within existing recovery ecosystems. The final sample included 565 PRSS. Results indicate that PRSS frequently provide emotional support to persons they work with and are overwhelmingly satisfied with their work but have few professional advancement opportunities and generally feel that others misunderstand their role. They have a strong voice and wish to be heard as evidenced by their responses to open text questions and interest in future work. This baseline survey can serve as the beginning of a framework for improved methods if driven by PRSS

The Effect of Elevation on Factors Influencing Adult Body Size of Asynarchus Nigirculus

Across the range of a species realized niche, individuals can face a range of environmental factors that change as you move from the central range towards the edge. These changes in environmental factors can have a significant impact on the fitness of an individual. In insects, one way to determine this impact is to study the difference in adult body size across the span of the species range. In western Colorado, caddisflies are the biomass dominant detritivores in alpine pond ecosystems. Caddisflies are fundamental in providing nutrients to the ecosystem because of the nutrients that they recycle as detritivores. Understanding how elevation and other factors affect caddisfly fecundity is key to understanding how climate change will affect alpine communities globally. To have a better understanding of this concept, I studied 23 ponds ranging from 2,347 to 3,505 meters in elevation and analyzed how elevation, density, sex, pond type and year affected the adult body size of the caddisfly Asynarchus nigriculus. I collected density samples of these species in each pond throughout the summer. Pupae were placed in emergence chambers, and adults were collected and measured. Elevation had a significant positive effect while density had a significant negative effect on the adult body size of Asynarchus. The effect of pond type on Asynarchus body weight was almost significant in that adults were almost significantly larger in permanent ponds. Adults in 2004 were significantly larger than adults in other years, and females were significantly larger than males. These findings can help of have a better understanding of how alpine ecosystem processes may be changing in the future. In the past years, new species of caddisflies have begun to shift their range into higher elevations. This movement could have a significant impact on the existing caddisfly populations as well as how energy is flowing through the system. This study is important because understanding how climate change affects species that are part of foundational guilds may help us better understand its far-reaching effects on ecosystems

Pre-service teacher implementation of strategy instruction: Effects on the comprehension of middle school students

Recent legislation related to dyslexia has increased the focus on how reading is being taught in schools and how teachers are prepared to teach reading at the pre-service level. One promising teaching approach to supporting students with reading difficulties is the self- regulated strategy development (SRSD) model. However, there is limited research regarding whether the model can be implemented by pre-service teachers while still remaining effective. This study investigated the effects and fidelity of implementation of pre-service teacher implemented SRSD on the reading comprehension of middle school students identified as struggling in reading. A multiple baseline design across participants was used. Two undergraduate, pre-service teachers provided instruction. Participants were seven middle school students that demonstrated reading comprehension deficits. All instruction was provided in pairs or small groups. Results indicate that pre-service teachers can adhere to SRSD components and have a positive effect on students’ reading comprehension when implementing SRSD. Ideas for future research and implications are discussed

Comparison of Parent-Implemented and Clinician-Directed Intervention for Toddlers Identified as Late Talkers: A Literature Review

Claire had been worried about her son Henry for several months. He did not seem to talk like other children his age and did not say as many words as his older sister when she was a toddler. Claire consulted with Henry\u27s pediatrician at his two-year wellness check. They discussed Henry\u27s medical history and, other than his lack of words, neither had concerns about his development. He really seems to understand everything we say to him or tell him to do, Claire explained, But he barely says anything at all. She decided to contact her local public school district for a speech-language evaluation. An early intervention speech-language pathologist (SLP) conducted a comprehensive assessment and concluded that Henry had an expressive language delay. & a late talker, he qualified to receive early intervention special-education services through the school district. The SLP explained the intervention model employed by the school district in which the SLP would guide the intervention and the parent, through natural daily routines, would directly provide Henry\u27s treatment. Claire was unsure about moving forward with this plan of care because she envisioned the SLP working directly with Henry. Claire decided to check with another SLP in a private practice setting. The second SLP described how, if she were treating Henry, she would see him herself for about an hour a week. Claire could either sit in on the session or wait in the waiting area while Henry was in therapy, but she would not be expected to carry out the treatment directly. Claire had a decision to make: Should she move forward with the homebased parent-implemented services offered by the school district or should she consider center-based SLP-directed services? What would be better for Henry
