Teleconsultation with a Developing Country: Student Reported Outcomes of Learning

This qualitative study explored the benefits of implementing (international) teleconsultation in a Master of Science in Occupational Therapy (MSOT) curriculum. Twenty-one students provided supervised teleconsultative services to individuals with disabilities in Guatemala and were responsible for completing assessments, setting goals, and providing resources to address goals and improve quality of life.  Data were collected through student presentations and coded for relevant themes. Analysis revealed new learning in the areas of the occupational therapy process, cultural awareness, and technology. Three themes emerged:  Increased Understanding of Awareness of and Challenges to Working with People of Different Culture; Need for Adaptability and Flexibility as Practicing Clinicians; Emerging Role of Technology in Occupational Therapy. Based on results from this study, occupational therapy academicians should consider implementing similar programs into curricula and conduct related research in order to promote not only student learning, but also to advance the use of technology in occupational therapy practice.        

High and Low Involvement: An Exploration of Ethical Product Decisions

Purpose Ethical elaboration is an aspect of product involvement and this research examines the relationship between involvement and ethical consumption providing a more holistic understanding of ethical decision-­making. This paper identifies antecedents of both low and high involvement ethical product decision-­making at farmers’ markets, and with sustainable and energy efficient features in the housing market, respectively. Design/methodology/approach These aims are achieved through semi-­structured and in-­depth interviews with consumers and sellers of ethical products across low and high involvement domains. Findings The empirical investigation reveals new insights into the constructs considered when purchasing high involvement ethical products. Barriers are discussed and findings examine the relationships between trust, information, ethical motivation and signalling. Research implications A research process framework for the study of ethical decision-­making is presented, demonstrating that constructs are approached differently between involvement levels. A conceptual model providing steps for transferring knowledge gained from the research to practice is also developed. Practical implications This research aids in the dispersion of information among stakeholders so that sustainability and energy efficiency can be part of the standard real estate conversation. Social implications Sustainability and energy efficiency (SEE) housing is seen as a niche market and this research will help alter the behaviour of the stakeholders in order to incentivise consumers to change their purchase patterns to include SEE features. Originality/value Most of the work on ethical consumption deals with low-­involvement products. This study addresses high-­involvement ethical consumption within the housing market through a qualitative approach

Scale properties of the seismic wavefield - perspectives for full waveform matching

Starting from the nondimensionalization of equations of motion we partition the set of the velocity models in equivalence classes, such that the full waveform of an element in a given class can be calculated from the full waveform of any other element in the same class by scaling model parameters. We give a formal derivation of the seismic wavefield scale properties and we prove their capability through the use of numerical examples. Besides this, we introduce how the scale properties can be used to save computational time in full waveform modeling and inversion. In forward modeling we can use them for the calculation of the full waveform of any model in the same equivalence class of a model whose full waveform has been previously calculated. In full waveform inversion, scale properties can be used for full waveform matching: Given an experimental seismogram and a synthetic one, we can choose, in the same class of the synthetic model, another element whose waveform is closer to the experimental on

Interpretation of microtremor 2D array data using Rayleigh and Love waves: the case study of Bevagna (central Italy)

In the last decades, geophysicists and seismologists have focused their attention on the inversion of empirical surface-waves’ dispersion curves from microtremor measurements for estimating the Swaves velocity structure at a site. This procedure allows a fast and convenient investigation without strong active sources, which are difficult to deploy especially in urban areas. In this study we report on a 2D seismic noise array experiment carried out at Bevagna (Central Italy) near the station BVG of the Italian Accelerometric Network (RAN). The site was investigated within the DPC-INGV S4 Project (2007-2009). The Rayleigh- and Love- waves dispersion characteristics were estimated using different methods. The inversion of the dispersion curves was then performed independently, obtaining two estimations for the S-waves velocity profiles. The results of cross-hole logging near the seismic station are used for a comparison. The shear waves velocity profiles estimated by microtremor analyses range up to 150m depth. The two independent procedures provide consistent shear waves velocity profiles for the shallow part of the model (20-30 m in depth) in agreement with the results of the cross-hole logging. Some problems arise between 30 and 40 m in depth in the profile estimated by surface waves. In this range cross-hole logging evidences an inversion of S-waves velocity. Although the cross-hole logging stops at 40 m of depth, we are confident about the results provided by the Rayleigh-waves analysis below 40-50 m. This case study suggests that greater efforts should be devoted to exploit the potential of a coupled analysis of Rayleigh and Love waves from microtremor array measurements

On the mechanical and electronic properties of thiolated gold nanocrystals

This article is part of themed collection: 2015 Hot Papers in Nanoscale.-- arXiv:1412.7698v1.-- et al.We present a quantitative exploration, combining experiment and simulation, of the mechanical and electronic properties, as well as the modifications induced by an alkylthiolated coating, at the single nanoparticle (NP) level. We determined the response of the NPs to external pressure in a controlled manner using an atomic force microscope tip. We found a strong reduction in their Young's modulus, as compared to bulk gold, and a significant influence of strain on the electronic properties of the alkylthiolated NPs. Electron transport measurements of tiny molecular junctions (NP/alkylthiol/CAFM tip) show that the effective tunnelling barrier through the adsorbed monolayer strongly decreases by increasing the applied load, which translates in a remarkable and unprecedented increase in the tunnel current. These observations are successfully explained using simulations based on the finite element analysis (FEA) and first-principles calculations that permit one to consider the coupling between the mechanical response of the system and the electric dipole variations at the interface.P.L. is a Senior Research Associate from the Fund for Scientific Research of Belgium (F.R.S. – FNRS).

Association of Sleep Duration with Obesity among US High School Students

Increasing attention is being focused on sleep duration as a potential modifiable risk factor associated with obesity in children and adolescents. We analyzed data from the national Youth Risk Behavior Survey to describe the association of obesity (self-report BMI ≥95th percentile) with self-reported sleep duration on an average school night, among a representative sample of US high school students. Using logistic regression to control for demographic and behavioral confounders, among female students, compared to 7 hours of sleep, both shortened (≤4 hours of sleep; adjusted odds ratio (95% confidence interval), AOR = 1.50 (1.05–2.15)) and prolonged (≥9 hours of sleep; AOR = 1.54 (1.13–2.10)) sleep durations were associated with increased likelihood of obesity. Among male students, there was no significant association between obesity and sleep duration. Better understanding of factors underlying the association between sleep duration and obesity is needed before recommending alteration of sleep time as a means of addressing the obesity epidemic among adolescents

A novel simplified mathematical model for antennas used in medical imaging applications

In this paper a new technique is proposed to model the current across a monopole antenna and thereby the radiation fields of the antenna can be calculated. Generally, the Method of Moments (MOM) technique is used for this purpose whereby the integral equations are discretised to find the fields of an antenna. The proposed model requires only the knowledge of three parameters (Initial Current I0, Damping coefficient a and the radial parameter ?) and hence considerably reduces the computational time and space as its results do not depend on the number of functions involved. The new technique is also developed to take account of the conductivity property of the surrounding medium. Hence this technique can be used in field prediction for antennas employed in medical imaging applications. Initial results obtained from the new technique show good correlation in comparison with the MOM technique
