The role of technology in overcoming disability : an individualized technology plan for students with dyslexia
The purpose of this study was to identify the technology skills and strategies that students with dyslexia use to overcome their learning disability. The literature suggests that there are many technologies that help students with dyslexia. However, the problem is that many students, families, and teachers do not know the skills and strategies that are most effective. The literature suggests many strategies that aid dyslexics performance in reading and writing. This research uses an Individualized Technology Plan to identify the technology skills and strategies that eighth grade students are using at a technology enriched independent school for students with language-based learning disabilities. This study compares student performance on the Test of Written Language (TOWL) when administered with a handwritten narrative and with a word processed narrative. The results indicate that students improve an average of 2.3 grade levels when they use a computer on written conventions and written language. All students use at least one technology strategy to help them with reading and an average of three technology strategies with writing. In conclusion, teaching students with dyslexia technology strategies for reading and writing makes a significant difference in their performance
Community Leaders\u27 Views on Water Quality BMPs in Kansas
Determining which strategic communications efforts can encourage environmentally sustainable behavior requires information on barriers to that behavior. To help assess a Kansas water quality program, researchers examined focus group data from community leaders interested in water issues. Working within the context of the theory of planned behavior and two broader conceptual frameworks, researchers found several major themes indicating support for a broad-based approach to water quality programs. Themes included concepts of home and place, awareness and understanding, relationships, ownership of issues, and money. Findings generally confirmed the need to emphasize multiple points at which intervention strategies can occur, including communication and diffusion instruments. Improved educational programs, informational efforts aimed at urban audiences and producer groups, and use of local information sources were cited as areas in which communications efforts would be valuable in water quality programs
AN ANALYSIS OF SAFETY CULTURE & SAFETY TRAINING: COMPARING THE IMPACT OF UNION, NON-UNION, AND RIGHT TO WORK CONSTRUCTION VENUES
The construction industry is one of the most dangerous sectors of the US economy. As such, the safety attitudes and climate within small (residential) contracting firms may play a role in providing a safe culture and working environment. The intent of this practitioner-based research study is to compare and determine if there is a difference in safety practices—based on documented field inspections and their related original number of violations observed by OSHA—between union residential carpentry contractors in the St. Louis area and:
1) non-union residential carpentry contractors in the St. Louis area;
2) non-union residential carpentry contractors across Missouri; and
3) non-union carpentry contractors in the four contiguous Right to Work (Nebraska, Kansas, Oklahoma, and Arkansas) states to Missouri, solely under federal OSHA compliance.
Three separate T-tests (for independent samples) were utilized to measure the outcomes of the various groups observe
Neuropsychological outcome following minimal access subtemporal selective amygdalohippocampectomy.
PURPOSE: The present study provides a detailed account of neurocognitive outcome following minimal access subtemporal selective amygdalohippocampectomy (SAH) and establishes rates of neurocognitive decline in the largest sample to date. Use of a subtemporal surgical approach to SAH has been proposed to possibly reduce the risk for postoperative neurocognitive decline since lateral neocortical tissues is not resected and the temporal stem is preserved. The current study extends prior research with subtemporal SAH patients to include not only group level analyses but also analyses based on reliable change data.
METHODS: Neurocognitive comparisons are made between 47 patients that underwent subtemporal SAH. Statistical comparisons were made between neurocognitive performance at the group level and with use of reliable change scores.
RESULTS: Approximately 75% of patients were seizure free postoperatively. At the group level, there were no significant postoperative changes. For the left SAH patients, reliable change scores demonstrated a decline in approximately one third of patients for memory, verbal intellect, and naming. Right SAH patients showed decline primarily in memory.
CONCLUSIONS: These results indicated good seizure control following subtemporal SAH with greatest risk for neurocognitive decline following dominant SAH and best cognitive outcome following non-dominant SAH. Findings demonstrated the importance of reliable change analyses that make individual based comparisons and take into account measurement error. Despite preservation of the lateral neocortical tissue and the temporal stem, subtemporal SAH presents a risk for cognitive decline in a notable portion of patients
Recreation and Wildlife Activity in the Wood River Valley
As the human population grows, people increasingly seek to recreate on public lands. Consequently, humans and animals find themselves sharing space. It is important, therefore, to understand how humans and wildlife interact in these natural spaces. The Big Wood River Watershed in Blaine County, Idaho is an excellent example of a natural area with a high density of recreational activity. This study aims to determine whether frequency and/or intensity of recreational activity affects wildlife activity. Data was collected using a combination of camera trapping and use of autonomous recording units. We expected that areas with high levels of recreational activity and high average sound would correlate with low wildlife activity and also that wildlife would change their activity patterns to avoid interaction with recreationists. Early analysis, however, indicates that the relationship between recreation and wildlife activity is more nuanced. These results will provide insight into public land management and how to best balance recreationist demands for access to lands with needs of wildlife
Exploring Individual and Structural Factors Associated with Employment Among Young Transgender Women of Color Using a No-Cost Transgender Legal Resource Center
Purpose: The purpose of this study was to explore individual and structural factors associated with employment among young transgender women (TW) of color.
Methods: Sixty-five trans women of color were recruited from the Transgender Legal Defense and Education Fund to complete a 30-min interviewer-assisted survey assessing sociodemographics, housing, workplace discrimination, job-seeking self-efficacy, self-esteem, perceived public passability, and transactional sex work.
Results: Logistic regression models revealed that stable housing (structural factor) and job-seeking self-efficacy (individual factor) were significantly associated with currently being employed.
Conclusion: Our findings underscore the need for multilevel approaches to assist TW of color gain employment
NFIRAOS First Facility AO System for the Thirty Meter Telescope
NFIRAOS, the Thirty Meter Telescope's first adaptive optics system is an
order 60x60 Multi-Conjugate AO system with two deformable mirrors. Although
most observing will use 6 laser guide stars, it also has an NGS-only mode.
Uniquely, NFIRAOS is cooled to -30 C to reduce thermal background. NFIRAOS
delivers a 2-arcminute beam to three client instruments, and relies on up to
three IR WFSs in each instrument. We present recent work including: robust
automated acquisition on these IR WFSs; trade-off studies for a common-size of
deformable mirror; real-time computing architectures; simplified designs for
high-order NGS-mode wavefront sensing; modest upgrade concepts for
high-contrast imaging.Comment: ..submitted to SPIE 9148 Astronomical Telescopes and Instrumentation

DICER1 tumor predisposition syndrome: An evolving story initiated with the pleuropulmonary blastoma
DICER1 syndrome (OMIM 606241, 601200) is a rare autosomal dominant familial tumor predisposition disorder with a heterozygous DICER1 germline mutation. The most common tumor seen clinically is the pleuropulmonary blastoma (PPB), a lung neoplasm of early childhood which is classified on its morphologic features into four types (IR, I, II and III) with tumor progression over time within the first 4-5 years of life from the prognostically favorable cystic type I to the unfavorable solid type III. Following the initial report of PPB, its association with other cystic neoplasms was demonstrated in family studies. The detection of the germline mutation in DICER1 provided the opportunity to identify and continue to recognize a number seemingly unrelated extrapulmonary neoplasms: Sertoli-Leydig cell tumor, gynandroblastoma, embryonal rhabdomyosarcomas of the cervix and other sites, multinodular goiter, differentiated and poorly differentiated thyroid carcinoma, cervical-thyroid teratoma, cystic nephroma-anaplastic sarcoma of kidney, nasal chondromesenchymal hamartoma, intestinal juvenile-like hamartomatous polyp, ciliary body medulloepithelioma, pituitary blastoma, pineoblastoma, primary central nervous system sarcoma, embryonal tumor with multilayered rosettes-like cerebellar tumor, PPB-like peritoneal sarcoma, DICER1-associated presacral malignant teratoid neoplasm and other non-neoplastic associations. Each of these neoplasms is characterized by a second somatic mutation in DICER1. In this review, we have summarized the salient clinicopathologic aspects of these tumors whose histopathologic features have several overlapping morphologic attributes particularly the primitive mesenchyme often with rhabdomyoblastic and chondroid differentiation and an uncommitted spindle cell pattern. Several of these tumors have an initial cystic stage from which there is progression to a high grade, complex patterned neoplasm. These pathologic findings in the appropriate clinical setting should serve to alert the pathologist to the possibility of a DICER1-associated neoplasm and initiate appropriate testing on the neoplasm and to alert the clinician about the concern for a DICER1 mutation
Real-Time Ligand Binding of Fluorescent VEGF-A Isoforms that Discriminate between VEGFR2 and NRP1 in Living Cells
© 2018 The Author(s) Fluorescent VEGF-A isoforms have been evaluated for their ability to discriminate between VEGFR2 and NRP1 in real-time ligand binding studies in live cells using BRET. To enable this, we synthesized single-site (N-terminal cysteine) labeled versions of VEGF165a, VEGF165b, and VEGF121a. These were used in combination with N-terminal NanoLuc-tagged VEGFR2 or NRP1 to evaluate the selectivity of VEGF isoforms for these two membrane proteins. All fluorescent VEGF-A isoforms displayed high affinity for VEGFR2. Only VEGF165a-TMR bound to NanoLuc-NRP1 with a similar high affinity (4.4 nM). Competition NRP1 binding experiments yielded a rank order of potency of VEGF165a > VEGF189a > VEGF145a. VEGF165b, VEGF-Ax, VEGF121a, and VEGF111a were unable to bind to NRP1. There were marked differences in the kinetic binding profiles of VEGF165a-TMR for NRP1 and VEGFR2. These data emphasize the importance of the kinetic aspects of ligand binding to VEGFR2 and its co-receptors in the dynamics of VEGF signaling. Peach et al. have used fluorescent VEGF-A isoforms to demonstrate that they can discriminate between VEGFR2 and its co-receptor NRP1 in real-time ligand binding studies in live cells. This precision chemical biology approach showed that fluorescent VEGF165a binds more rapidly to NRP1 than VEGFR2
