This article reviews PROC IRT, which was added to Statistical Analysis Software in 2014. We provide an introductory overview of a free version of SAS, describe what PROC IRT offers for item response theory (IRT) analysis and how one can use PROC IRT, and discuss how other SAS macros and procedures may compensate the IRT functionalities of PROC IRT.

Biomedical research increasingly relies on the analysis and visualization of a wide range of collected data. However, for certain research questions, such as those investigating the interconnectedness of biological elements, the sheer quantity and variety of data results in rather uninterpretable--this is especially true for network visualization,…

Information Technology (IT) departments that include development and operations are essential to develop software that meet customer needs. DevOps is a term originally constructed from software development and IT operations. DevOps includes the collaboration of all stakeholders such as software engineers and systems administrators involved in the…

Purpose: Assessment of strained voice quality is difficult due to the weak reliability of auditory-perceptual evaluation and lack of strong acoustic correlates. This study evaluated the contributions of relative fundamental frequency (RFF) and mid-to-high frequency noise to the perception of strain. Method: Stimuli were created using recordings of…

Emerging regulations require higher education financial aid staff to handle many tasks. Complying with these regulations and participating in mandated compliance audits are complex processes that require numerous departments to work in concert. This article discusses what steps colleges and universities can take to improve their compliance audits.…

A word's exterior letters, particularly its initial letter, appear to have a special status when reading. Therefore, most orthographic coding models incorporate assumptions giving initial letters and, in some cases, final letters, enhanced importance during the orthographic coding process. In the present article, 3 masked priming experiments were…

The user interface (UI) is a key component of an interactive software application; therefore, it is important to provide software developers with basic UI design skills. However, teaching UI design is challenging, even at a basic level, and there is little teaching support. In this article, we investigate the benefits of the feedback-enriched…

The growth of technology has impacted billions of lives by allowing people to connect with others through social media platforms such as Facebook, Twitter, Skype, WhatsApp, and so on. Despite the advantages of technology, there has been notable resistance from employees, especially the older generations, who are not eager to adopt social media…

This study focused on the use of casual games to motivate learners in a corporate retail settings to engage in a online learning platform. The study analyzed two populations of learners who were using the learning platform. One group of learners was in a game condition. In this condition, the learners were provided the option to play a casual game…

Self-regulated learning (SRL) is associated with increased academic achievement and improved learning outcomes for students. Thus, it is import to find ways to improve SRL, such as through training. Face-to-face training, discipline-dependent training, and paper-and-pencil diaries are limited in the number of students they can reach. The current…

The NASA public archives present a vast resource of authentic satellite data that research astronomers have tapped into for decades. Recently, the same data analysis tools used by professional astronomers have been adapted into a browser-based interface called JS9 for easy use by any interested student. Tutorials and classroom-ready activities…

MATLAB live scripts are useful for reproducible programmatic compilation of chemical data and literature. In this article, we use a combination of the PubChem PUG REST Application Programming Interface (API), Structured Data Query (SDQ) agent, and text extraction with MATLAB live scripts that allow programmatic PubChem similarity searching, SMARTS…

GitHub is increasingly finding a role in academia to both encourage reproducible computational research and to foster a collaborative environment. We show that employing GitHub as an implementation of version control in engineering-related fields reinforces the 'design-build-evaluate' way of thinking and prepares students with skills they can use…

As the technology landscape is continually evolving, transitions to newer software are commonplace in higher education. Change is often difficult to navigate, especially when the change that is implemented fundamentally impacts entrenched business processes. In no place is this more evident than when implementing a new system, whether the…

This case describes a classroom activity that explores a fictional software product company to help students learn about ways that businesses make money from software, including Free & Open Source Software (FOSS). The activity shows how a company might evolve through different business models, but does not imply that some models are always…
