Predicting needlestick and sharps injuries in nursing students: Development of the SNNIP scale

2020

© 2020 The Authors. Nursing Open published by John Wiley & Sons Ltd. Aim: To develop an instrument to investigate knowledge and predictive factors of needlestick and sharps injuries (NSIs) in nursing students during clinical placements. Design: Instrument development and cross-sectional study for psychometric testing. Methods: A self-administered instrument including demographic data, injury epidemiology and predictive factors of NSIs was developed between October 2018–January 2019. Content validity was assessed by a panel of experts. The instrument's factor structure and discriminant validity were explored using principal components analysis. The STROBE guidelines were followed. Results: E…

Refining distraction potential testing guidelines by considering differences in glancing behavior

2021

Driver distraction is a recognized cause of traffic accidents. Although the well-known guidelines for measuring distraction of secondary in-car tasks were published by the United States National Highway Traffic Safety Administration (NHTSA) in 2013, studies have raised concerns on the accuracy of the method defined in the guidelines, namely criticizing them for basing the diversity of the driver sample on driver age, and for inconsistent between-group results. In fact, it was recently discovered that the NHTSA driving simulator test is susceptible to rather fortuitous results when the participant sample is randomized. This suggests that the results of said test are highly dependent on the s…

Finnish students’ enjoyment and anxiety levels during fitness testing classes

2020

Background: Fitness testing is a commonly applied learning and teaching practice implemented in both secondary and elementary school physical education (PE). Many teachers believe that by using a variety of different tests, they are able to provide students with feedback regarding their fitness status, and furthermore, increase students’ willingness to be physically active later in their lives. However, empirical evidence concerning students’ affective responses during fitness testing classes is limited. Purpose: The primary aim of the study was to investigate whether students’ perceptions of enjoyment and anxiety differed between two different types of fitness testing classes and PE in gen…

The Severe Asthma Registry – German data

2018

Patients with severe persistent asthma represent the highest unmet medical need among the asthmatic population. To improve the understanding of underlying mechanisms and disease progression the German Asthma Net (GAN, www.german-asthma-net.de) launched a Severe Asthma Registry in December 2011. Enrolled patients undergo detailed clinical and physiologic evaluations, including patients’ medical history, allergy and lung function tests, blood analyses as well as past and concomitant medication and comorbidities. Patients are followed up every year. As of February 2018, 1097 subjects were recruited in Germany, Austria, and Slovenia. The mean age±SEM of the 839 German adult patients is 50.6±0.5…

O início de uma nova era: teste sistemático para patógenos causadores de infecções agudas das vias aéreas superiores (IVAS) em crianças

2007

On average humans get sick ten times per year. About six times the illness is due to an acute respiratory tract infection (ARI). Morbidity is especially high in children since they usually encounter the offending organism for the first time in their life; the lack of immunity results in shedding of the offending organisms in high numbers of prolonged time as compared to adults; their airways are smaller than those of adults and thus the inflammatory response leads to a more significant narrowing of the airways resulting in more severe disease; on average they have a high number of social contacts and also a more intimate contact with peers and caregivers alike resulting in a higher attack r…

Comparison of mechanical properties and composition of magnetron sputter and plasma enhanced atomic layer deposition aluminum nitride films

2018

A comparative study of mechanical properties and elemental and structural composition was made for aluminum nitride thin films deposited with reactive magnetron sputtering and plasma enhanced atomic layer deposition (PEALD). The sputtered films were deposited on Si (100), Mo (110), and Al (111) oriented substrates to study the effect of substrate texture on film properties. For the PEALD trimethylaluminum–ammonia films, the effects of process parameters, such as temperature, bias voltage, and plasma gas (ammonia versus N2/H2), on the AlN properties were studied. All the AlN films had a nominal thickness of 100 nm. Time-of-flight elastic recoil detection analysis showed the sputtered films t…

Benchmark study of undrained triaxial testing of Opalinus Clay shale: Results and implications for robust testing

2021

Triaxial testing of argillaceous rocks and shales is significantly more challenging than conventional rock mechanical testing. The challenges are mainly related to the very low permeability of these geomaterials, and their sensitivity to exposure of atmosphere and brines, which induces variations of water content, suction and effective stress. There are currently no international standards to guide service laboratories for robust testing procedures for shales. A benchmark study of undrained triaxial testing was therefore initiated with three leading service laboratories in shale testing, performing 13 tests and using two different methods of establishing sample saturation prior to deformati…

Validity of a novel device for indoor analysis of cyclists' drag area

2021

Cyclists need to measure aerodynamic resistance accurately and reliably, as well as economically. Devices such as Notio Aerostick, an equipment device that includes one pitot tube, have appeared for this purpose. The aim of this study is, therefore, to test the reliability and degree of agreement in the evaluation of the CdA (coefficient of aerodynamic drag), assessed by means of the Notio Aerostick compared to the Virtual Elevation (VE) and Martin mathematical models.Seventeen professional cyclists rode in a 250-metre-long velodrome covered with a concrete surface with their own time trial bikes. Each cyclist completed three rides of 15 laps at constant speed for the evaluation of the CdA,…

Revista electrónica de investigación y evaluación educativa

2014

Actualmente existe un interés creciente por la calidad educativa y la atención a la diversidad. En este trabajo se presenta un análisis de dos aspectos importantes: el “Contexto” en el que el centro debe de desarrollar su actividad y  las “metas y objetivos” que un centro educativo debe definir para dar una respuesta de calidad a la diversidad. Analizaremos el grado de importancia para los profesores y el nivel de cumplimiento en los centros, a partir de los datos obtenidos en dos cuestionarios. El estudio se realizó con profesores de la provincia de A Coruña (España). En líneas generales podemos decir que los aspectos analizados son considerados importantes por los profesores como indicado…
