School aged children: Visual perception and reversal recognition of letters and numbers separately and in context

Visual discrimination, spatial orientation, and recognition of letters and numbers in context are important issues in helping young students achieve good literacy and numeracy standards. Thus, measures of Visual Discrimination of Upper Case Letters (VDUCL), Visual Discrimination of Lower Case Letters (VDLCL), and Visual Discrimination of Numbers (VDN) as well as Spatial Orientation of Letter and Number Pairs (SOLNP), Form Constancy of Letters and Numbers (FCLNP), Letter and Number Sequencing (LNS), Figure Ground of Letters in Words FGLW) and Figure Ground Numbers in Calculations (FGNC) must be linear and uni-dimensional so that student weaknesses can be identified objectively. The Simple Logistic Model of Rasch Measurement was used to order the items on a scale from easy to difficult and the student measures were calibrated on the same scale from low to high. In each scale, items were scored zero (for incorrect) and one (for correct). The student sample N=324 used in this study included pre-primary and primary students in Perth, Western Australia. The initial data were adjusted so that items which displayed misfit statistics were removed from each scale prior to final analysis. The final VDUCL scale (18 items), VDLCL scale (31 items), and VDN scale (14 items) each had a good fit to the measurement model, and were internally reliable. In each scale, there was good agreement about the item difficulties from easy to hard along the scale. Item discrimination and targeting was good. The scales allow teachers to objectively identify the letters and numbers that students find difficult to discriminate and those students who have poor visual discrimination skills of alphabet letters and numbers so that tailored teaching can be applied to those in need

Visual Recognition Difficulties: Identifying Primary School Students\u27 Directional Confusion In Writing Letters And Numbers

Background: Occupational therapists often assess primary school learners for letter and number reversal tendencies using scales which require recognition of reversed letters and numbers; however, these scales do not generally look at learners’ written production of letters and numbers to measure their reversal tendencies. This study aimed to determine whether learners reverse the same letters and numbers in reading and in writing. Method: This study utilised the Richmond Reversal Rating (RRR) Scale to identify which language symbols 118 primary school learners found difficult to recognise as being reversed when reading a series of letters and numbers and writing 20 letters and nine numerals. Analysis: Nonparametric correlations and parametric Chi-square statistics were used to investigate differences in the learners’ reading recognition and written production. Results: Letters and numbers reversed in recognition (reading) and writing were similar. Moreover, eleven letters and three numbers were identified as difficult to orientate on a page. Conclusion: Explicit teaching to remediate letter and number reversals and font use are paramount to improving language symbol orientation

An Investigation of Service Providers’ understanding, perspectives and implementations of the Transdisciplinary model in Early Intervention settings for Children with Disabilities

Purpose: The transdisciplinary practice model is currently being promoted as best practice in early intervention therapy for children with disabilities. However, supporting literature is limited. Thus, the question is asked, “What are service providers\u27 understanding and perception of the transdisciplinary model in early intervention settings for children with disabilities?” Method: A systematic review was carried out using the Preferred Reporting Items for Systematic Reviews. An electronic search was conducted via six databases. Eight articles were selected. Results: Four studies predominantly focused on service providers’ perspectives of the model using semi-structured interviews or surveys. Many studies were of adequate to low quality, and the methods of implementing the transdisciplinary approach varied across organisations. It is therefore difficult to draw valid conclusions based on service provider’s viewpoints of the model. Conclusions: This review attempted to determine if the transdisciplinary model is best practice. The inconsistencies in the transdisciplinary teams indicates that overall, the general understanding of the model and its framework amongst organisations is poor. Further research is needed to establish service providers’ understanding of the model and how transdisciplinary teams are functioning since the introduction of the National Disability Insurance Scheme

A systematic review of the impact of powered mobility devices on older adults\u27 activity engagement

Purpose: To systematically review the impact powered mobility devices have on engagement in independent occupations for adults with acquired mobility limitations. Method: Electronic search of CINAHL Plus, Medline, PsychInfo, OT Seeker, Joanna Briggs Institute, and Physiotherapy Evidence Database. Search terms included combinations of words to encompass all terms most likely used for powered mobility. Results: Eleven studies were eligible for inclusion. One study was a true experimental design; four studies were pre-experimental, and six were nonexperimental. Studies indicated positive improvements to occupational engagement and independence while environmental barriers were identified as negatively impacting occupation and increasing risk of injury or accident. Conclusions: Drawing conclusions from this research are problematic due to varying methodological quality. This review suggested two distinct themes: environmental barriers generate difficulties and challenges, which can subsequently result in accident or injury, and access to powered mobility impacts positively on areas of independence, quality of life, mobility and engagement

In Vivo Analysis of Conserved C. elegans Tomosyn Domains

Neurosecretion is critically dependent on the assembly of a macromolecular complex between the SNARE proteins syntaxin, SNAP-25 and synaptobrevin. Evidence indicates that the binding of tomosyn to syntaxin and SNAP-25 interferes with this assembly, thereby negatively regulating both synaptic transmission and peptide release. Tomosyn has two conserved domains: an N-terminal encompassing multiple WD40 repeats predicted to form two β-propeller structures and a C-terminal SNARE-binding motif. To assess the function of each domain, we performed an in vivo analysis of the N- and C- terminal domains of C. elegans tomosyn (TOM-1) in a tom-1 mutant background. We verified that both truncated TOM-1 constructs were transcribed at levels comparable to rescuing full-length TOM-1, were of the predicted size, and localized to synapses. Unlike full-length TOM-1, expression of the N- or C-terminal domains alone was unable to restore inhibitory control of synaptic transmission in tom-1 mutants. Similarly, co-expression of both domains failed to restore TOM-1 function. In addition, neither the N- nor C-terminal domain inhibited release when expressed in a wild-type background. Based on these results, we conclude that the ability of tomosyn to regulate neurotransmitter release in vivo depends on the physical integrity of the protein, indicating that both N- and C-terminal domains are necessary but not sufficient for effective inhibition of release in vivo

Working sandwich generation women utilize strategies within and between roles to achieve role balance

Increasingly, women simultaneously balance the roles of mother, parental carer and worker. However, individual role balance strategies among these working \u27sandwich\u27 generation women have not been thoroughly explored. Eighteen women combining these three roles were interviewed about their individual role balance strategies. Findings were identified through the framework analysis technique, underpinned by the Model of Juggling Occupations. Achieving and maintaining role balance was explained as a complex process accomplished through a range of strategies. Findings revealed the women used six within-role balance strategies: living with integrity, being the best you can, doing what you love, loving what you do, remembering why and searching for signs of success. The women also described six between-role balance strategies: maintaining health and wellbeing, repressing perfectionism, managing time and energy, releasing responsibility, nurturing social connection and reciprocating. These findings provide a basis for health care providers to understand and potentially support working \u27sandwich\u27 generation women. © 2016 Evans et al.

Infrastructural Speculations: Tactics for Designing and Interrogating Lifeworlds

This paper introduces “infrastructural speculations,” an orientation toward speculative design that considers the complex and long-lived relationships of technologies with broader systems, beyond moments of immediate invention and design. As modes of speculation are increasingly used to interrogate questions of broad societal concern, it is pertinent to develop an orientation that foregrounds the “lifeworld” of artifacts—the social, perceptual, and political environment in which they exist. While speculative designs often imply a lifeworld, infrastructural speculations place lifeworlds at the center of design concern, calling attention to the cultural, regulatory, environmental, and repair conditions that enable and surround particular future visions. By articulating connections and affinities between speculative design and infrastructure studies research, we contribute a set of design tactics for producing infrastructural speculations. These tactics help design researchers interrogate the complex and ongoing entanglements among technologies, institutions, practices, and systems of power when gauging the stakes of alternate lifeworlds
