VALIDITY, RELIABILITY AND FEASIBILITY OF MEASURING MUSCLE ACTIVITY WITH TEXTILE ELECTRODES EMBEDDED INTO CLOTHING
2007
INTRODUCTION In out-of-laboratory settings the surface EMG measurements are complicated by the requirement of careful electrode placement and skin preparation. The development of washable textile electrodes that can be sowed into sportswear enable muscle activity recordings during normal locomotion without skin preparation and the problem of wires hanging around the body [1]. In this study we performed validity, reliability and feasibility tests of the textile electrodes embedded into shorts against the traditional bipolar surface electrodes.
Recommendations for ecotoxicity testing with stygobiotic species in the framework of groundwater environmental risk assessment.
2019
As a consequence of the growing global dependence on groundwater resources, environmental risk assessments (ERA) for groundwater are increasingly required and, with that, ecotoxicological studies with groundwater fauna (stygofauna). However, the literature on the ecotoxicological studies with stygobiotic species (i.e. species that complete their life cycle exclusively in groundwater) has not expanded significantly since the first paper published in this field. The limitations regarding the use of stygobiotic species for ecotoxicological testing are clear and consistent across the globe; stygobiotic species are often 1) naturally present in low numbers, 2) difficult to collect, and 3) diffic…
The International Guideline Evaluation Screening Tool (IGEST): development and validation.
2022
Abstract Background Guideline adaptation provides an important alternative to de novo guideline development by making the process more efficient and reducing unnecessary duplication. The quality evaluation of international guidelines is an essential part of the adaptation process. The study aims at describing the development and validation of a new tool to screen trustworthy Clinical Practice Guidelines (CPGs) for their adoption/adaption: the International Guideline Evaluation Screening Tool (IGEST). Methods The process of developing the IGEST involved two main phases: 1) tool development and 2) content validation. The tool development phase comprised three stages, where the scope of the IG…
MECANISMOS DE COORDINACIÓN ESTRUCTURAL, NO ESTRUCTURAL E INFORMAL. PROPUESTA Y VALIDACIÓN DE ESCALAS DE MEDIDA / STRUCTURAL, NON- STRUCTURAL AND INFO…
2008
El presente trabajo tiene como objetivo diseñar y validar escalas para medir diversos mecanismos de coordinación estructural, no estructural e informal. Los primeros están vinculados a puestos u órganos específicos, y nos referimos al diseño de redes, equipos de proyecto y desarrollo, y equipos de trabajo. Los mecanismos de coordinación no estructural sirven de complemento a los anteriores. En este grupo se encuentran la normalización de procesos de trabajo, de habilidades y de resultados. Por último, los mecanismos de carácter informal son el esfuerzo de socialización y la adaptación mutua. Tras la generación de una batería de 43 ítems, se han comprobado sus propiedades psicométricas: fiab…
Design of the EBE-ST Questionnaire among Nursing Students: Multicenter Study from Eight Universities in Spain
2021
Background: Twenty years after the degree in nursing was introduced in Spain, the subject of evidence-based nursing is still unstructured and unestablished in most faculties. Moreover, there are hardly any rigorous studies at a national level that evaluate the current state of this competence in our faculties. Understanding the starting point is essential for the curricular design to ensure that evidence-based practice is implemented among future professionals. Aim: To design and validate an evidence-based nursing competency questionnaire for fourth-year nursing students. Methods: A specific questionnaire was developed and validated (EBE-ST). A cross-sectional survey design with psychometri…
VALIDITY AND INVARIANCE OF MEASUREMENT OF THE SATISFACTION WITH LOVE LIFE SCALE IN OLDER ADULTS
2020
In recent years, interest in satisfaction with love life (SWLL) has increased. Empirical evidence demonstrated that SWLL favors subjective well-being, physical and mental health, marital quality and stability. In this regard, the study aimed to examine evidence based on the internal structure validity, reliability, and measurement invariance of the Peruvian version of the Satisfaction with Love Life Scale (SWLLS). The participants were 323 older adults recruited from the region of San Martin (Peru) with an average age of 68.73 years (SD = 7.17). The sample comprised of 49.5% women and 50.5% men. The results supported the one-dimensional model and adequate reliability of the SWLLS. A multi-g…
The structure of Antonovsky's Orientation to Life Questionnaire
1998
The present study investigated the structure of Antonovsky's (1987) short-form (13-item) Orientation to Life Questionnaire (OLQ). The OLQ was developed to measure sense of coherence, which consists of three interrelated components: meaningfulness, comprehensibility and manageability. Confirmatory factor analyses were carried out using data on three occupational groups (technical designers n = 989, teachers n = 1012, managers n = 1035). The factor analysis models were specified and compared in the study: (1) a first-order one-factor model; (2) a first-order correlated-three-factor model; and (3) a second-order model with three first-order factors. The results suggested that the first-order c…
A New Reliable and Valid Tool for Measuring Implicit Self-Esteem
2012
We investigated the reliability and predictive validity of a new response-window affective priming task (RW-APT) for the measurement of implicit self-esteem. Participants (N = 96) were administered the self-esteem RW-APT and filled out two measures of explicit self-esteem. To investigate the effect of explicit and implicit self-esteem on reactions to failure, we applied an anagram task in which participants received anagrams that were more difficult than expected. Three self-esteem criteria were obtained: pretask expectancy bias, perceived performance bias, and posttask expectancy bias. As hypothesized, explicit self-esteem and implicit self-esteem measures independently predicted all vali…
A comprehensive study of automatic program repair on the QuixBugs benchmark
2021
Abstract Automatic program repair papers tend to repeatedly use the same benchmarks. This poses a threat to the external validity of the findings of the program repair research community. In this paper, we perform an empirical study of automatic repair on a benchmark of bugs called QuixBugs, which has been little studied. In this paper, (1) We report on the characteristics of QuixBugs; (2) We study the effectiveness of 10 program repair tools on it; (3) We apply three patch correctness assessment techniques to comprehensively study the presence of overfitting patches in QuixBugs. Our key results are: (1) 16/40 buggy programs in QuixBugs can be repaired with at least a test suite adequate pa…
Automated Patch Assessment for Program Repair at Scale
2021
AbstractIn this paper, we do automatic correctness assessment for patches generated by program repair systems. We consider the human-written patch as ground truth oracle and randomly generate tests based on it, a technique proposed by Shamshiri et al., called Random testing with Ground Truth (RGT) in this paper. We build a curated dataset of 638 patches for Defects4J generated by 14 state-of-the-art repair systems, we evaluate automated patch assessment on this dataset. The results of this study are novel and significant: First, we improve the state of the art performance of automatic patch assessment with RGT by 190% by improving the oracle; Second, we show that RGT is reliable enough to h…
