When in the fall semester of 2017 at the University of Pittsburgh at Bradford, a Laboratory was added to Linear Circuits I , it provided an absolute amazing insight into the absence of practical knowledge of students. They could not identify resistors, or capacitors. They had in most cases no idea what a DMM was and how to use it. Setting up fairly simple circuits on a proto-board and making voltage and current measurements had to be shown to each Lab group. A Lab experiment with an Op-Amp meant, that several of the Op-Amps were sacrificed to the smoke god. Students were amazed by what an Oscilloscope could do and how one could see the charge and discharge of a capacitor. At the end of each experiment, MatLab was used to verify the practical results obtained. What was gratifying at the end of the semester that each student group had high praise for the inclusion of a Laboratory into the curriculum. All the frustration and the extra work involved was worth it if one looked at the final result and that a practical component had been added to the students background, which would serve them well in a summer internship or in the Co-op program.

Insight Into

Peer Support Programmes (PSPs) have long been a feature of student engagement activity at the University of Exeter.  Peer Support at Exeter started over eight years ago, with just two discipline-specific programmes. Since then, the number of programmes has increased significantly, but throughout this period of growth the bespoke nature of the programmes has been retained.  All PSPs are student-led and, crucially, they are tailored to meet the specific needs of the student group involved.  We, the authors, are firmly of the opinion that ‘one size does not fit all’ and that tailoring every programme to the specific needs of each student group is vital if it is to be successful.  It is now recognised that engagement in interventions such as PSPs can play an important role in improving student retention and success (Thomas, 2012) and that an understanding of ‘local contexts’ can enhance the efficacy of such programmes (Thomas et al, 2017).  However, this was not as well understood when PSPs were first introduced at Exeter. This short paper seeks to present an overview of the evolution of PSPs at the University of Exeter, which may provide others with a useful insight into the development of tailored PSPs for optimal student engagement.

A joint center has been established by the University of Pittsburgh and the Excerpta Medica Foundation. The basic objective of the Center is to seek ways in which the health sciences community may achieve increasingly convenient and economical access to scientific findings. The research center will make use of facilities and resources of both participating institutions. Cooperating from the University of Pittsburgh will be the School of Medicine, the Computation and Data Processing Center, and the Knowledge Availability Systems (KAS) Center. The KAS Center is an interdisciplinary organization engaging in research, operations, and teaching in the information sciences.Excerpta Medica Foundation, which is the largest international medical abstracting service in the world, with offices in Amsterdam, New York, London, Milan, Tokyo and Buenos Aires, will draw on its permanent medical staff of 54 specialists in charge of the 35 abstracting journals and other reference works prepared and published by the Foundation, the 700 eminent clinicians and researchers represented on its International Editorial Boards, and the 6,000 physicians who participate in its abstracting programs throughout the world. Excerpta Medica will also make available to the Center its long experience in the field, as well as its extensive resources of medical information accumulated during the Foundation’s twenty years of existence. These consist of over 1,300,000 English-language _abstract of the world’s biomedical literature, indexes to its abstracting journals, and the microfilm library in which complete original texts of all the 3,000 primary biomedical journals, monitored by Excerpta Medica in Amsterdam are stored since 1960.The objectives of the program of the combined Center include: (1) establishing a firm base of user relevance data; (2) developing improved vocabulary control mechanisms; (3) developing means of determining confidence limits of vocabulary control mechanisms in terms of user relevance data; 4. developing and field testing of new or improved media for providing medical literature to users; 5. developing methods for determining the relationship between learning and relevance in medical information storage and retrieval systems’; and (6) exploring automatic methods for retrospective searching of the specialized indexes of Excerpta Medica.The priority projects to be undertaken by the Center are (1) the investigation of the information needs of medical scientists, and (2) the development of a highly detailed Master List of Biomedical Indexing Terms.

ABSTRACT Many people may not be aware of the extent of Kurt Kyser's collaboration with mineral exploration companies through applied research and the development of innovative exploration technologies, starting at the University of Saskatchewan and continuing through the Queen's Facility for Isotope Research. Applied collaborative, geoscientific, industry-academia research and development programs can yield technological innovations that can improve the mineral exploration discovery rates of economic mineral deposits. Alliances between exploration geoscientists and geoscientific researchers can benefit both parties, contributing to the pure and applied geoscientific knowledge base and the development of innovations in mineral exploration technology. Through a collaboration that spanned over three decades, we gained insight into the potential for economic uranium deposits around the world in Canada, Australia, USA, Finland, Russia, Gabon, Namibia, Botswana, South Africa, and Guyana. Kurt, his research team, postdoctoral fellows, and students developed technological innovations related to holistic basin analysis for economic mineral potential, isotopes in mineral exploration, and biogeochemical exploration, among others. In this paper, the business of mineral exploration is briefly described, and some examples of industry-academic collaboration innovations brought forward through Kurt's research are identified. Kurt was a masterful and capable knowledge broker, which is a key criterion for bringing new technologies to application—a grand, curious, credible, patient, and attentive communicator—whether talking about science, business, or life and with first ministers, senior technocrats, peers, board members, first nation peoples, exploration geologists, investors, students, citizens, or friends.

Background: Sensing of biomedical signals is crucial for monitoring of various health conditions. These signals have a very low amplitude (in μV) and a small frequency range (<500 Hz). In the presence of various common-mode interferences, biomedical signals are difficult to detect. Instrumentation amplifiers (INAs) are usually preferred to detect these signals due to their high commonmode rejection ratio (CMRR). Gain accuracy and CMRR are two important parameters associated with any INA. This article, therefore, focuses on the improvement of the gain accuracy and CMRR of a low power INA topology. Objective: The objective of this article is to achieve high gain accuracy and CMRR of low power INA by having high gain operational amplifiers (Op-Amps), which are the building blocks of the INAs. Methods: For the implementation of the Op-Amps and the INAs, the Cadence Virtuoso tool was used. All the designs and implementation were realized in 0.18 μm CMOS technology. Results: Three different Op-Amp topologies namely single-stage differential Op-Amp, folded cascode Op-Amp, and multi-stage Op-Amp were implemented. Using these Op-Amp topologies separately, three Op-Amp-based INAs were realized and compared. The INA designed using the high gain multistage Op-Amp topology of low-frequency gain of 123.89 dB achieves a CMRR of 164.1 dB, with the INA’s gain accuracy as good as 99%, which is the best when compared to the other two INAs realized using the other two Op-Amp topologies implemented. Conclusion: Using very high gain Op-Amps as the building blocks of the INA improves the gain accuracy of the INA and enhances the CMRR of the INA. The three Op-Amp-based INA designed with the multi-stage Op-Amps shows state-of-the-art characteristics as its gain accuracy is 99% and CMRR is as high as 164.1 dB. The power consumed by this INA is 29.25 μW by operating on a power supply of ±0.9V. This makes this INA highly suitable for low power measurement applications.

The scholarship of student affairs has neglected to carefully review its contextual past and, in the process, failed to fully integrate historical research into practice. The story of Thyrsa Wealtheow Amos and the history of the Dean of Women’s Program at the University of Pittsburgh,1919–41, helps us to reflect on the true reality of our work in higher education. Although seemingly a time in the distant past, Thyrsa Amos embodied the spirit of student personnel administration that shines ever so bright to thisd ay. The purpose of this research is to provide some of thatcontext and remind us of the values that serve as foundations of the profession.

Abstract Context Questions remain about bariatric surgery for type 2 diabetes mellitus (T2DM) treatment. Objective Compare the remission of T2DM following surgical or nonsurgical treatments. Design, setting, and participants Randomized controlled trial at the University of Pittsburgh, in the United States. Five-year follow-up from February 2015 until June 2016. Interventions 61 participants with obesity and T2DM who were initially randomized to either bariatric surgical treatments (Roux-en-Y gastric bypass [RYGB] or laparoscopic adjustable gastric banding [LAGB]) or an intensive lifestyle weight loss intervention (LWLI) program for 1 year. Lower level lifestyle weight loss interventions (LLLIs) were then delivered for 4 years. Main Outcomes and Measures Diabetes remission assessed at 5 years. Results The mean age of the patients was 47 ± 6.6 years, 82% were women, and 21% African American. Mean hemoglobin A1c level 7.8% ± 1.9%, body mass index (BMI) 35.7 ± 3.1 kg/m2, and 26 participants (43%) had BMI &lt; 35 kg/m2. Partial or complete T2DM remission was achieved by 30% (n = 6) of RYGB, 19% (n = 4) of LAGB, and no LWLI participants (P = .0208). At 5 years those in the RYGB group had the largest percentage of individuals (56%) not requiring any medications for T2DM compared with those in the LAGB (45%) and LWLI (0%) groups (P = .0065). Mean reductions in percent body weight at 5 years was the greatest after RYGB 25.2% ± 2.1%, followed by LAGB 12.7% ± 2.0% and lifestyle treatment 5.1% ± 2.5% (all pairwise P &lt; .01). Conclusions Surgical treatments are more effective than lifestyle intervention alone for T2DM treatment.

Insight Into

An Australian College of Operating Room Nurses (ACORN) submission (ACORN 2002–2008) recently stated that the specialities that suffered significantly from the transition of hospital-based nursing training to university training were the perioperative specialty, critical care and emergency. The main reason for this was that perioperative nursing was not included in the undergraduate nursing curriculum. Less than a handful of universities in Australia offer the subject as a compulsory unit. The University of Notre Dame Australia (UNDA) is one of these universities. This paper will provide an insight into the perioperative nursing care unit embedded within the Bachelor of Nursing (BN) undergraduate curriculum.
