ABSTRACTTraditional lecture-centered approaches alone are inadequate for preparing students for the challenges of creative problem solving in the STEM disciplines. As an alternative, learnercentered and other high-impact pedagogies are gaining prominence. The Wabash College 3D Printing and Fabrication Center (3D-PFC) supports several initiatives on campus, but one of the most successful is a computer-aided design (CAD) and fabrication-based undergraduate research internship program. The first cohort of four students participated in an eight-week program during the summer of 2015. A second group of the four students was successfully recruited to participate the following summer. This intensive materials science research experience challenged students to employ digital design and fabrication in the design, testing, and construction of inexpensive scientific instrumentation for use in introductory STEM courses at Wabash College. The student research interns ultimately produced a variety of successful new designs that could be produced for less than $25 per device and successfully detect analytes of interest down to concentrations in the parts per million (ppm) range. These student-produced instruments have enabled innovations in the way introductory instrumental analysis is taught on campus. Beyond summer work, the 3D-PFC staffed student interns during the academic year, where they collaborated on various cross-disciplinary projects with students and faculty from departments such as mathematics, physics, biology, rhetoric, history, classics, and English. Thus far, the student work has led to three campus presentations, four presentations at national professional conferences, and three peer-reviewed publications. The following report highlights initial progress as well as preliminary assessment findings.

Background: Ameloblastoma is the second most common odontogenic tumor. It shows a locally aggressive behavior, with a high level of recurrence. Wide resection of the jaw is recommended for treatment of ameloblastoma. However, radical surgery causes an abnormal mandibular movement, facial asymmetry, and masticatory dysfunction. Methods: Three cases of different types of ameloblastoma is presented, with different reconstruction techniques including Non-Vascularized Bone Graft (NVBG), Osteocutaneous Fibula Free Flap (OFFF), and Deep Circumflex Iliac Artery flap (DCIA). Results: In all three cases the tumor site was successfully reconstructed to obtain very good esthetic results as well as functional oral rehabilitation with implants and fixed prosthetics for optimal masticatory function. Conclusion: For reconstruction of the mandible, we prefer bone grafts from the iliac crest. The natural curvature and variable bone height offer a very good reconstruction of the defect.

From 2010 to 2013, the White Mountain Apache Tribe and the University of Arizona, with funding from the National Science Foundation, hosted the Western Apache Ethnography and Geographic Information Science Research Experience for Undergraduates. Designed to foster practical skills and scholarly capacities for future resource managers and anthropologists, this field school introduced Apache and non-native undergraduate students to ethnographic field research and GIS tools. Building upon the extensive arrays of geographical, cultural, and historical data that are available for Western Apache territory, field school students engaged in community-based participatory research with Western Apache elders and tribal natural and heritage resource personnel to contribute to the Western Apache tribes' efforts to document their cultural histories, traditional ecological knowledge, local understanding of geography, and issues of historic and contemporary resource management. This essay reviews the program and traces how student alumni have incorporated skills and perspectives gained into their subsequent academic and professional work.

This chapter shows how to develop an answer to a particular research question. It first considers the requirements and components of an answer to a research question before discussing the role of ‘theory’ in social science research, what a ‘theoretical framework’ is, and what a hypothesis is. It then explores the three components of a hypothesis: an independent variable, a dependent variable, and a proposition (a statement about the relationship between the variables). It also looks at the different types of hypotheses and how they guide various kinds of research. It also explains why conceptual and operational definitions of key terms are important and how they are formulated. Finally, it offers suggestions on how to answer normative questions.

A Review of: Chang, Y-W. (2017). Comparative study of characteristics of authors between open access and non-open access journals in library and information science. Library & Information Science Research, 39(1), 8-15. http://dx.doi.org/10.1016/j.lisr.2017.01.002   Abstract  Objective – To examine the occupational characteristics and publication habits of library and information science (LIS) authors regarding traditional journals and open access journals. Design – Content analysis. Setting – English language research articles published in open access (OA) journals and non-open access (non-OA) journals from 2008 to 2013 that are indexed in LIS databases. Subjects – The authorship characteristics for 3,472 peer-reviewed articles. Methods – This researcher identified 33 total journals meeting the inclusion criteria by using the LIS categories within 2012 Journal Citation Reports (JCR) to find 13 appropriate non-OA journals, and within the Directory of Open Access Journals (DOAJ) to identify 20 appropriate OA journals. They found 1,665 articles by 3,186 authors published in the non-OA journals, and another 1,807 articles by 3,446 authors within the OA journals. The researcher used author affiliation to determine article authors’ occupations using information included in the articles themselves or by looking for information on the Internet, and excluded articles when occupational information could not be located. Authors were categorized into four occupational categories: Librarians (practitioners), Academics (faculty and researchers), Students (graduate or undergraduate), and Others. Using these categories, the author identified 10 different types of collaborations for co-authored articles. Main Results – This research involves three primary research questions. The first examined the occupational differences between authors publishing in OA journals versus non-OA journals. Academics (faculty and researchers) more commonly published in non-OA journals (58.1%) compared to OA journals (35.6%). The inverse was true for librarian practitioners, who were more likely to publish in OA journals (53.9%) compared to non-OA journals (25.5%). Student authors, a combined category that included both graduate and undergraduate students, published more in non-OA journals (10.1%) versus in OA journals (5.0%). The final category of “other” saw only a slight difference between non-OA (6.3%) and OA (5.5%) publication venues. This second research question explored the difference in the proportion of LIS authors who published in OA and non-OA journals. Overall, authors were more likely to publish in OA journals (72.4%) vs. non-OA (64.3%). Librarians tended to be primary authors in OA journals, while LIS academics tend to be primary authors for articles in non-OA publications. Academics from outside the LIS discipline but contributing to the disciplinary literature were more likely to publish in non-OA journals. Regarding trends over time, this research showed a decrease in the percentage of librarian practitioners and “other” authors publishing in OA journals, while academics and students increased their OA contributions rates during the same period.  Finally, the research explored whether authors formed different types of collaborations when publishing in OA journals as compared to non-OA journals. When examining co-authorship of articles, just over half of all articles published in OA journals (54.4%) and non-OA journals (53.2%) were co-authored. Overall the researcher identified 10 types of collaborative relationships and examined the rates for publishing in OA versus non-OA journals for these relationships. OA journals saw three main relationships, with high levels of collaborations between practitioner librarians (38.6% of collaborations), between librarians and academics (20.5%), and between academics only (18.0%). Non-OA journals saw four main relationships, with collaborations between academics appearing most often (34.1%), along with academic-student collaborations (21.5%), practitioner librarian collaborations (15.5%), and librarian-academic collaborations (13.2%). Conclusion – LIS practitioner-focused research tends to appear more often in open access journals, while academic-focused researcher tends to appear more often in non-OA journals. These trends also appear in research collaborations, with co-authored works involving librarians appearing more often in OA journals, and collaborations that include academics more likely to appear in non-OA journals.

Light microscopes in laboratories and hospitals are used for examining many different types of samples—from industrial research to life-science research and clinical screening. These procedures use conventional bright-field, differential phase contrast (DIC), and fluorescence microscopy among other techniques. In all cases, the light source on the microscope has a crucial influence on the quality of images viewed and the conclusions reached.

Music therapy is a common approach to reduce stress and anxiety levels. To examine the effect of different types of music on stress levels, forty Generalized Anxiety Disorder (GAD) patients were assigned randomly to one of four groups exposed to a specific kind of music described in this research. The electroencephalogram (EEG) was recorded from Cz placement along with skin conductance and temperature recordings for each subject. Also, commonly used clinical questionnaires were used to determine the patients, stress levels. In the classical music group, significant increments in the alpha relative power occurred. Additionaly, in the preferred music group, the relative power of the beta EEG rhythm significantly decreased. These results were compatible with clinical results. Our study showed that music therapy for GAD patients could be used as a powerful method to reduce stress and anxiety. Furthermore, the skin conductance is analyzed and incremental increase in two groups is observed.
