Abstract:

Functional near infrared spectroscopy (fNIRS) is a neuroimaging technique that allows to monitor the functional hemoglobin oscillations related to cortical activity. One of the main issues related to fNIRS applications is the motion artefact removal, since a corrupted physiological signal is not correctly indicative of the underlying biological process. A novel procedure for motion artifact correction for fNIRS signals based on wavelet transform and video tracking developed for infrared thermography (IRT) is presented. In detail, fNIRS and IRT were concurrently recorded and the optodes’ moveme

Abstract:

This case study explores how an emergent bilingual preschooler used transmodal practices to engage with objects and compose narratives in sociodramatic play. Video recordings and field notes were collected in a dual language preschool classroom in the United States to examine the actional, verbal, and visual modes used by the focal child during his engagement with objects. An action-oriented analysis using multimodal discourse and mediated action frameworks revealed how he transmodally engaged with play artifacts to embody imagined roles and extend objects’ functionality.

Abstract:

Sampling is a fundamental practice of many scientific disciplines. However, K–12 students are rarely asked to think critically about sampling decisions. Because of this, open questions remain about how best to support students in this practice. This study explores the emergent sampling practice of two classes of sixth-grade students as they investigate the ecology of a local creek. It draws on student interviews, pre/post-tests, student artifacts, and video recordings of classroom activity to identify and trace shifts in the ways in which students approached collecting data. The findings sugge

Although previous studies have underlined the importance of social interactions, multicultural education, prediction/imagination, and bilingual/bi-literacy learning, the intersection of all these four areas is yet to be explored. This qualitative case study explored how young bilingual readers create meanings and develop literary responses through prediction, imagination, and social interaction while reading multicultural literature. As part of a larger longitudinal study, this study focused on kindergarten-age Korean-English bilingual children at a Korean Language School in a Midwestern city

This study attempts to promote social reflection and cultural recognition in the multicultural scenario of the classroom. This is a qualitative study carried out with ninth grade students at a public school in Bogotá. The main objective is enrolling the students in critical pedagogy practices that allow them the construction of the sense of Other. The experience was implemented through the students’ exposure to authentic historical facts in which they acquired knowledge about social, political, and cultural issues. This exposure then encouraged reflection during the classes, empowering the stu

Abstract:

A wood cantilever of length ∼2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic ( n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and physical dimensions of the cantilever. Experimental frequencies agree with theoretical ones to within their respective uncertainties. Experiments described here can be incorporated seamlessly into introductory college physics laboratories, following

Determining the cause of poor libido in stallions can be challenging. Many factors can cause disturbance in libido (e.g., lameness or physical pain, hormonal, age, experience, and handling). Identifying the cause of poor libido is important to determine the best treatment approach. A 6-year Thoroughbred stallion was presented for failure of intromission when attempting to breed mares. Stallion was recently retired from racing. Stallion was placed on hormonal therapy that did not change stallion’s aberrant reproductive behavior. On presentation no obvious physical causes were identified and the

Accurate measurement of cardiomyocyte contraction is a critical issue for scientists working on cardiac physiology and physiopathology of diseases implying contraction impairment. Cardiomyocytes contraction can be quantified by measuring sarcomere length, but few tools are available for this, and none is freely distributed. We developed a plug-in (SarcOptiM) for the ImageJ/Fiji image analysis platform developed by the National Institutes of Health. SarcOptiM computes sarcomere length via fast Fourier transform analysis of video frames captured or displayed in ImageJ and thus is not tied to a d
