The focus and timing of gaze matters : Investigating collaborative knowledge construction in a simulation-based environment by combined video and eye…

2022

Although eye tracking has been successfully used in science education research, exploiting its potential in collaborative knowledge construction has remained sporadic. This article presents a novel approach for studying collaborative knowledge construction in a simulation-based environment by combining both the spatial and temporal dimensions of eye-tracking data with video data. For this purpose, we have investigated two undergraduate physics student pairs solving an electrostatics problem in a simulation-based environment via Zoom. The analysis of the video data of the students’ conversations focused on the different collaborative knowledge construction levels (new idea, explication, eval…

Electromyographic Studies in Abdominal Exercises: A Literature Synthesis

2008

Abstract Objective The purpose of this article is to synthesize the literature on studies that investigate electromyographic activity of abdominal muscles during abdominal exercises performance. Methods MEDLINE and Sportdiscus databases were searched, as well as the Web pages of electronic journals access, ScienceDirect, and Swetswise, from 1950 to 2008. The terms used to search the literature were abdominal muscle and the specific names for the abdominal muscles and their combination with electromyography, and/or strengthening, and/or exercise, and/or spine stability, and/or low back pain. The related topics included the influence of the different exercises, modification of exercise positi…

Nonadherence in outpatient thrombosis prophylaxis with low molecular weight heparins after major orthopaedic surgery

2010

Background: According to some current guidelines, extended thromboprophylaxis after hip and knee arthroplasties is recommended. Outpatient prophylaxis with low molecular weight heparins (LMWH) is an important part of this prophylaxis, although the rates of adherence to these regimens is not known. Questions/purposes: We determined (1) the degree of nonadherence (NA) of patients with LMWH outpatient prophylaxis, and (2) whether specific independent factors explain NA. Methods: NA was determined by syringe count and by indirect and direct questions to patients. We defined six different NA indicators. To identify factors explaining LMWH NA, we used three different logistic regression models. R…

Preliminary Experience with a Novel System of Facet Fixation to Treat Patients with Lumbar Degenerative Disease. A New Perspective in Minimally Invas…

2017

Purpose We report our experience with a novel surgical device for the treatment of lumbar degenerative microinstability. Facet Wedge (DePuy Synthes, Raynham, Massachusetts, United States) is a novel technique of intra-articular lumbar facet fixation that provides a minimally invasive alternative to standard posterior fixation. Materials and Methods From November 2014 to July 2015, 38 patients underwent single-level Facet Wedge implantation. The main surgical indications included herniated disk (18 patients), spinal canal and foraminal stenosis (14 patients), and Meyerding grade I degenerative spondylolisthesis (6 patients). All the patients showed radiologic signs of microinstability: hype…

Revista electrónica de investigación y evaluación educativa

2014

Resumen tomado de la publicación Título, resumen y palabras clave en inglés y español La igualación equipercentil es un método estadístico en el cual los puntajes crudos de dos versiones de una prueba se consideran igualados si ellos corresponden al mismo rango percentilar en un grupo de examinados. En la igualación equipercentil se presenta una curva para describir las diferencias de dificultad de versión a versión. Se tiene como objetivo estimar la igualación equipercentil sin suavizado de las versiones 3 y 4, con la versión 2, por área temática del Examen de Habilidades y Conocimientos Básicos (EXHCOBA) que utiliza la Universidad Autónoma de Baja California (UABC) para la selección de as…

Early Career Women in Academia: An Exploration of Networking Perceptions

2016

This chapter explores women’s networking perceptions by focusing on early career women in social sciences. Within an exploratory research design it asks how early career women define the early career stage in academia, what definitions, meanings and interpretations they give for networks and networking, how they construct the networking process and their ability to establish and/or join networks, as early career researchers and as women. Based on two group interviews with 12 participants, our findings show that early career women in academia favour networking with peers based on shared interests (organic networking). At the same time though, they challenge and step over the perceived gender…

The contribution of the pre-existing structures in mountain belt evolution: the example of the negative inversion in the Northen Sicily

2004

Syn-orogenic extension has been recognised in Northern Sicily. Mesoscopic analysis has been carried out in three key areas, where folded-and-thrust Mesozoic-to-Tertiary rocks crop-out. The three examples are inherent to Portions Of tectonic Units Which occupy progressively more internal positions in the Sicilian chain from west to east. The extensional deformation is mainly represented by low-angle normal faults and shear bands. A common kinematic process seems to affect the other sector of the chain during the extension and is represented by a generalized negative inversion of previous layer-parallel shear bands and detachments related to the thrusting. The extensional deformation occurred…

Neoliberal Governmentality and Knowledge Production in Higher Education: Genealogy of a Subjective Configuration

2015

En este artículo, se parte de la consideración de que cualquier interrogación sobre las condiciones de posibilidad de una investigación crítica debe hacerse teniendo en cuenta el proceso de mercantilización del conocimiento, impulsado por la incorporación de los modos de gubernamentalidad neoliberal en la universidad. Proceso este que redefine el valor y el uso que se le da al conocimiento producido y redefine también las subjetividades de los colectivos universitarios: formas de entender el conocimiento y configuraciones subjetivas que promueven modos instrumentales de relacionarse con el conocimiento en un escenario individualizador y competitivo. Por ello, se considera políticamente rele…

Benefits and drawbacks of communication visibility : from vicarious learning and supplemental work to knowledge reuse and overload

2022

Purpose This study aims to examine some of the benefits and drawbacks of communication visibility. Specifically, building on communication visibility theory, the authors study how and why message transparency and network translucence may increase knowledge reuse and perceived overload through behavioral responses of vicarious learning and technology-assisted supplemental work. Design/methodology/approach Drawing on survey data obtained from 1,127 employees of a global company operating in the industrial machinery sector, the authors used structural equation modeling to test the hypothesized model. Findings The results demonstrate that the two aspects of communication visibility yield somew…
