Analysis of thermally induced flows in the laboratory by geoelectrical 3-D tomography
2010
[1] Many natural bodies as well as materials inside industrial installations, such as the Earth's mantle and the glass inside melting furnaces, exchange matter through convection. These processes result from differences in temperature, density, and chemical concentration. In this analysis, we focus on the visualization of thermally driven flows in the laboratory. In nature and in industrial installations, it is difficult to measure the temperature inside the object of interest directly. We benchmark a new DC-geoelectrical 3-D tomography method for temperature measurements that allows obtaining temperature values without influencing the flow pattern. For verification of the method, we use di…
High-fidelity simulation among bachelor students in simulation groups and use of different roles.
2013
Cost limitations might challenge the use of high-fidelity simulation as a teaching-learning method. This article presents the results of a Norwegian project including two simulation studies in which simulation teaching and learning were studied among students in the second year of a three-year bachelor nursing programme. The students were organised into small simulation groups with different roles; nurse, physician, family member and observer. Based on experiences in different roles, the students evaluated the simulation design characteristics and educational practices used in the simulation. In addition, three simulation outcomes were measured; knowledge (learning), Student Satisfaction an…
Psychometric properties of the stress control mindset measure in university students from Australia and the UK
2021
Abstract Introduction Beliefs about the consequences of stress, stress mindsets, are associated with health and performance outcomes under stress. This article reports the development and examination of the psychometric properties of a measure of stress mindset: The Stress Control Mindset Measure (SCMM). The measure is consistent with theory on mindsets about self‐attributes and conceptualizes stress mindset as the extent to which individuals endorse beliefs that stress can be enhancing. Methods The study adopted a correlational cross‐sectional survey design in two student samples. Undergraduate students from an Australian university (Sample 1, N = 218) and a UK university (Sample 2, N = 21…
Panorama de la Calidad de Vida Laboral entre Trabajadores que Prestan Cuidados Paliativos en Brasil
2019
Resumo Este artigo tem por objetivo oferecer um primeiro diagnóstico sobre os níveis de qualidade de vida dos trabalhadores brasileiros que prestam cuidados paliativos. Foram aplicadas escalas de medidas de qualidade de vida profissional, en-frentamento ante a morte, autocuidado profissional e autoconsciência em 161 profissionais. As análises de dados incluíram estatísticas descritivas, comparação dos níveis em função de sexo, idade e outras características sociodemográficas, e estudo da relação entre as variáveis mencionadas. Foram encontrados níveis adequados tanto nas variáveis de proteção da qualidade de vida profissional como na qualidade de vida em si. As comparações em função de dado…
Thermally Induced Structural Modification of Silica Nanoparticles Investigated by Raman and Infrared Absorption Spectroscopies
2010
We report an experimental investigation by Raman and infrared (IR) absorption spectroscopies on the structural modifications induced by isochronal thermal treatments on amorphous SiO2 nanoparticles (fumed silica). In particular, three different commercial types of this material, characterized by particle mean diameters of 7, 14, and 40 nm, were subjected to thermal treatments from 100 up to 1000 °C. We found that some properties of fumed silica, such as the SiOSi mean bond angle, ring size distribution, and surface adsorbed water content, are drastically different from those of common bulk silica materials and intimately related to the particles' dimension. The SiOSi mean bond angle, probed…
Incentive systems for risky investment decisions under unknown preferences
2017
Abstract Our paper examines how to design incentive systems for managers making multi-period risky investment decisions. We show how compensation functions and performance measures must be designed to ensure that managers implement the expected value-maximizing set of projects. The Relative Benefit Cost Allocation (RBCA) Scheme 1 and its extensions revealed in literature on unknown time preferences generally fail to do so under unknown time and risk preferences. We illustrate that when coping with such unknown preferences in a risky setting, a specific state-dependent allocation rule is required. We introduce such an allocation scheme, which we refer to as the State-Contingent RBCA Scheme, …
Assessment of tobacco dependence curricula in Italian dental hygiene schools
2013
The aim of this study was to assess the level of tobacco dependence education offered by Italian dental hygiene programs. A fifty-question survey was mailed to the thirty-one active public and private dental hygiene programs in Italy during the 2008-09 academic year. The survey assessed faculty confidence in teaching tobacco treatment, which courses contained tobacco dependence content, the number of minutes spent on specific content areas, and the level of clinical competence that dental hygiene graduates should be able to demonstrate. Surveys were returned by sixteen programs for a response rate of 52 percent. Respondents indicated tobacco dependence education was included in clinic or cl…
Impacto de las Prácticas de Recursos Humanos sobre la creatividad y los resultados de innovación : propuesta de una escala de medida
2014
La capacidad de innovar se ha convertido en un factor clave de éxito para la supervivencia de las empresas en los entornos actuales. La existencia de procesos creativos en las empresas conduce al desarrollo de productos y procesos innovadores. Además, la adecuación de las prácticas de Recursos Humanos a la estrategia de innovación favorece la creatividad y el proceso de innovación. El objetivo básico de este trabajo es la propuesta de un modelo teórico para el desarrollo de una escala de medida que conjugue los enfoques tradicionales de Recursos Humanos, más estáticos y orientados a los resultados, con los enfoques de innovación más dinámicos y centrados en los procesos. Así, la contribució…
Incomplete self-similarity and flow velocity in gravel bed channels
2000
Velocity measurements, previously carried out using both a miniature current flowmeter and an acoustic Doppler velocimeter, are used to verify the applicability of the incomplete self-similarity theory to deduce the velocity profile in a gravel bed channel. Then, for the velocity profiles having the maximum value below the free surface and for the S-shaped profiles, the power velocity distribution is corrected using a new divergence function. For each value of the depth sediment ratio the nondimensional friction factor parameter is calculated by integration of the measured velocity distributions in the different verticals of the cross section. Finally, a semilogarithmic flow resistance equa…
Assessing the measurement invariance of a Latin-American Spanish translation of the Body Appreciation Scale-2 in Mexican, Argentinean, and Colombian …
2020
In order to advance in the study of positive body image among different cultures, it is important to create culturally appropriate measures. We examined the psychometric properties of a Latin-American Spanish translation of the Body Appreciation Scale-2 (BAS-2; Tylka & Wood-Barcalow, 2015a), specifically assessing measurement invariance using a large sample of 3845 male and female adolescents from Argentina, Mexico, and Colombia. Participants completed the BAS-2, Eating Disorder Inventory-2, Male Body Attitude Scale and the Sociocultural Attitudes Toward Appearance Questionnaire-3. The BAS-2 had a unidimensional factor structure in each of the three samples. We confirmed the structural, met…
