Compressed sensing (CS) is an emerging signal acquisition framework that goes against the traditional Nyquist sampling paradigm. CS demonstrates that a sparse, or compressible, signal can be acquired using a low rate acquisition process. Since noise is always present in practical data acquisition systems, sensing and reconstruction methods are…

Institutions are accredited by three types of accreditors: national faith-related organizations that accredit religiously affiliated and doctrinally based institutions that are primarily degree-granting and nonprofit; national career-related organizations that accredit mainly for-profit career-based degree-granting and non-degree-granting…

Corpora have multiple affordances, not least for use by teachers and learners of a foreign language (L2) in what has come to be known as "data-driven learning" or DDL. The corpus and concordance interface were originally conceived by and for linguists, so other users need to adopt the role of "language researcher" to make the most of them. Despite…

This paper describes and analyses the pilot of one data collection tool, the work diary, for an educational research project. Before inclusion in the wider research project, the researcher developed, piloted and qualitatively assessed the feasibility of the data collection tool. As the wider research project will be conducted in and investigate…

NMR spectroscopy has become one of the primary tools that chemists utilize to characterize a range of chemical species in the solution phase, from small organic molecules to medium-sized proteins. A discussion of NMR spectroscopy is an essential component of physical and biophysical chemistry lecture courses, and a number of instructional…

Many physical educators are aware of the impact the tightening fiscal climate has on physical education programs at all levels. Shrinking resources have generated a need to protect and promote the quality of physical education programs in this country. Additionally, administrators need to be proactive when attempting to target physical education…

Rural communities often have distinct contextual factors that impact residents' substance abuse behavior. However, most studies to date have focused either exclusively on urban populations or neglected to analyze data in a way that allows any rural/urban comparison. This is especially true for research examining nonmedical prescription drug use…

This study examines the potential of visual sociology to expand our knowledge of higher education through the use of visual data sources and methods of analysis. Photographs and archival material form the basis of the study. The images were analyzed as being part of the initiation and fulfillment stages of the social construction of collective…

We examined whether the reason offered for electronic performance monitoring (EPM) influenced participants' performance, stress, motivation, and satisfaction. Participants performed a data-entry task in one of five experimental conditions. In one condition, participants were not electronically monitored. In the remaining conditions, participants…

School violence research is often concerned with infrequently occurring events such as counts of the number of bullying incidents or fights a student may experience. Analyzing count data using ordinary least squares regression may produce improbable predicted values, and as a result of regression assumption violations, result in higher Type I…

The identification of differential item functioning (DIF) is often performed by means of statistical approaches that consider the raw scores as proxies for the ability trait level. One of the most popular approaches, the Mantel-Haenszel (MH) method, belongs to this category. However, replacing the ability level by the simple raw score is a source…

Children will increasingly come of age with personified robots and potentially form social and even moral relationships with them. What will such relationships look like? To address this question, 90 children (9-, 12-, and 15-year-olds) initially interacted with a humanoid robot, Robovie, in 15-min sessions. Each session ended when an experimenter…

In this paper, I discuss how I came to call into question the way in which I interpreted interview data in my dissertation, which investigated the migration and settlement experience of Japanese women who are married to Australian men and reside in Australia. Through critical reflections, I realized the way in which the positionality of…

The objective of the study was to determine the hydrodynamics of the two stage counter-current cascade wet scrubbers used during incineration of medical waste. The dependence of the hydrodynamics on two main variables was studied: Inlet air flow rate and inlet liquid flow rate. This study introduces a new wet scrubber operating features, which are…

Maximum likelihood estimation of mixed effect baseline category logit models for multinomial longitudinal data can be prohibitive due to the integral dimension of the random effects distribution. We propose to use multidimensional unfolding methodology to reduce the dimensionality of the problem. As a by-product, readily interpretable graphical…
