Online learning is still a very contentious topic throughout the halls of academia. Advocates state that students who complete online courses learn as much as those in a face-to-face environment; earn equivalent grades; and, are equally satisfied. However, other researchers note that online students are less likely to complete their courses thereby negating the positive impact. Yet, online education is continuing its upward growth and in higher education, new degree programs and courses are being added on a regular basis. The Babson Survey Group reported that in 2011, online course enrollment hit an all-time high with more than 6.1 million students. The reported also stated that approximately thirty-one percent of all higher education students now take at least one course online. With the cost of education rising and employers looking for students with more depth in the subject area, there remains a debate regarding how to best deliver the educational experience to students. The aim of this paper is to present the development and results of a pilot study involving an online computer ethics course at a two-year institution. The paper positions the course within the context of the college's computer science curriculum, describes the rationale for course development and presents the next steps toward making the course a requirement for computer science majors.

Nucleoside reverse transcriptase inhibitors (NRTIs) are drugs used in the treatment of HIV/AIDS. Despite the distinct benefits of NRTI-based therapies, tissue specific toxicity is a limiting factor. Although the mechanisms of these specific antiretroviral drug-related toxicities remain unclear, it has been hypothesized that as analogs to native nucleosides, NRTIs may potentially inhibit mammalian DNA polymerases, including mitochondrial DNA (mtDNA) polymerase γ. Tenofovir disoproxil fumarate (TDF) is a nucleotide analog of adenosine monophosphate and the only NRTI that is associated with renal disease. The inherent heterogeneity of kidney tissues could affect the outcome and interpretation of molecular studies to define the mechanism(s) of tenofovir tubular toxicity. Laser-capture microdissection (LCM) provided a specific, single-cell isolation of proximal tubules from fixed heterogeneous kidney tissues. LCM-captured renal proximal tubules from transgenic mice (TGs) showed decreased mtDNA abundance with tenofovir, demonstrating a subcellular specific mitochondrial toxicity of tenofovir in an AIDS model. © 2011 Springer Science+Business Media, LLC.

PURPOSE: Obesity is a major public health issue in the United States. Dental hygienists influence their patients' oral health by providing dietary and behavioral recommendations that encourage good oral health practices. However, it is not known if they are ready to provide behavioral counseling strategies for weight loss. This study investigates whether dental hygienists in North Carolina are confident to counsel patients who are at-risk for obesity. METHODS: A questionnaire was used to survey 246 dental hygienists attending a continuing education (CE) course. It investigated self-reported confidence in providing obesity counseling, educational preparation, outcome expectations and self-efficacy. The primary outcome was confidence in providing weight loss counseling. Mantel Haenszel statistics were used to compare group of interest. RESULTS: Of the dental hygienists surveyed, 43% perceived an increase of overweight patients in their practices. Nearly all (95%) felt that dental hygienists have a role in helping patients improve nutrition. Over half (65%) expressed confidence in discussing obesity-related health risks. On average, the confidence in getting patients to follow weight loss advice was significantly different (p=0.02) for those with a 2 year degree and those with a 4 year degree. CONCLUSIONS: The findings indicate that many North Carolina dental hygienists are willing to discuss obesity with patients.

The electronic structure characteristics of silicon nanowires under strain and electric bias are studied using first-principles density functional theory. The unique wire-like structure leads to distinct spatial distribution of carriers, which can be tailored by applying tensile and compressive strains, as well as by an electric bias. Our results indicate that the combined effect of strain and electric bias leads to tunable electronic structures that can be used for piezo-electric devices. © 2014 Author(s).

In our increasingly data-centric world, statistical reasoning--in particular, reasoning about data in the context of uncertainty--has become central to the skills our nation needs for students to develop, especially for their future careers in the workforce. An undergraduate students first formal experience with statistical reasoning frequently occurs in classrooms dominated by lectures rather than active learning experiences. In addition, the classroom instructors often are relatively untrained in statistics. This is especially true at two-year colleges where adjunct instructors can find it difficult to take part in professional development opportunities, often perceive reform-based pedagogies as taking extra work when they already have an unreasonable workload, perceive new resources as being difficult to integrate into their current mode of instruction, and recognize the frequent severe statistics anxiety in their students. SMILES (Student-Made Interactive Learning with Educational Songs) for Introductory Statistics--a collaborative project from Pennsylvania State University - University Park, the University of Texas at El Paso, and Georgia Perimeter College--will develop and field-test an innovation in online learning in introductory statistics, where students create a song by filling in key words associated with a learning objective. These interactive songs will challenge students to make conceptual connections and construct examples or context, thereby fostering statistical literacy and reasoning skills. Through a reduction in statistics anxiety (a key impediment to student success) and an accompanying enhancement of student learning, the potential impact is striking.
The underlying goal of the project is to develop resources that require little instructor time or expertise, but have a high impact on developing statistical literacy and reasoning and on reducing statistics anxiety. In connection with this, interactive songs will provide a novel learning resource that holds great potential for teaching literacy and reasoning skills in statistics and other STEM disciplines. The web-based, machine-run, and auto-graded characteristic of this resource will provide easy access to students anywhere anytime, and will address instructor hesitations regarding in-class use. For instructors, interactive songs will be readily adoptable regardless of pedagogy (e.g., as easily incorporated in a flipped class as in an online class, or a lecture/lab course), and will provide a simple bridge to the statistics education reform movement for groups like two-year college adjunct faculty members who might remain otherwise disconnected. Most importantly, these professional-quality interactive songs will be designed to engage students, lessen anxiety, and foster active learning, thereby leading to improved statistical reasoning skills. To enhance their value, the interactive songs developed by the SMILES project will involve a unique artist/scientist collaborative to create original high-quality musical resources. To evaluate their efficacy and assess the value of interactive songs in enhancing student learning and reducing student anxiety, the project team will conduct a randomized controlled field test involving twenty (20) college level introductory statistics instructors for which fifteen (15) will be from two-year colleges. Response variables will include student answers to multiple-choice assessment items and levels of anxiety as measured by a pre-Statistics Anxiety Measure (SAM) and post-SAM measurement. Since students from the two-year colleges consist predominately of African American and Hispanic student populations, the research findings of the project will expand knowledge of best practices for addressing the national need to broaden participation in science, technology, engineering, and mathematics (STEM) discipline areas.
