A social constructivist approach to introducing skills for employment to Foundation Degree students

Expectations for higher education providers to produce graduates ready for the workplace have shaped provision, with the introduction of the Foundation Degree, and expectations of an employability component within higher education programmes. This paper reports on an intervention for three groups of foundation degree students, which introduces them to ideas of skills for employability. An initial evaluation was followed up two months later exploring the longer-term impact and connections within students' programmes of study and data were captured from employers and tutors supporting this intervention. In agreement with similar studies, benefits for students were identified. However, this research reinforces the challenging nature of the employability agenda, particularly within the context of Foundation Degrees and their dual vocational-academic remit. This paper suggests there is a case to be made for a social constructivist approach within programmes and institutions for promoting awareness and consistency in developing student employability skills. © 2013 © 2013 Further Education Research Association

Student and Faculty Perceptions of Live Synchronous Distance Education for Allied Health Students Following Program Expansion to a Rural Campus

Background & Purpose: Distance education (DE) is a means to meet allied health workforce needs in rural locations where healthcare worker shortages are apparent. Five allied health programs were expanded to a rural campus teaching synchronously using distance education technology. The purpose of this convergent parallel mixed methods study was to explore perceptions of allied health students and faculty at two campus locations. Methods: Quantitative and qualitative information were collected through a survey of students and faculty (physical therapy, physician assistant, and medical imaging [diagnostic medical sonography, radiography, magnetic resonance imaging] programs). Both campuses served as live and distance sites depending on instructor location and area of content expertise. For example, morning courses may be taught live from one campus, and afternoon classes taught live from the other campus. Only one program, physical therapy, offered labs by distance education. Response distributions were compared for questions by campus using Cochran-Armitage trend tests and analyzed de-identified qualitative comments using constant comparisons to establish themes. Results: Student (n=121) and faculty (n=19) mostly agreed distance education technology was effective for teaching and learning. Significant differences were found in student opinions about receiving a similar educational experience between the two campuses. More students at the Main campus somewhat or strongly disagreed (n=34, 37%) it was similar compared to the Rural campus (n= 5, 17%, p=0.024). There were no comments specifically related to the physical therapy lab experience. Open-ended comment themes included training, purposeful engagement of both campus locations, and setting clear expectations. Conclusions: Although differences in learning experiences exist between the main and rural campus locations; the results indicated using distance education technology is an effective means to deliver the curriculum. Both students and faculty commented about the lack of experience with the educational technology before implementation. Synchronous, distance education offers the opportunity for program expansion and effective delivery of curriculum content. Using the results of this study can enhance future education in allied health professions using synchronous distance education technology

MRI measures of middle cerebral artery diameter in conscious humans during simulated orthostasis.

BACKGROUND AND PURPOSE: The relationship between middle cerebral artery (MCA) flow velocity (CFV) and cerebral blood flow (CBF) is uncertain because of unknown vessel diameter response to physiological stimuli. The purpose of this study was to directly examine the effect of a simulated orthostatic stress (lower body negative pressure [LBNP]) as well as increased or decreased end-tidal carbon dioxide partial pressure (P(ET)CO(2)) on MCA diameter and CFV. METHODS: Twelve subjects participated in a CO(2) manipulation protocol and/or an LBNP protocol. In the CO(2) manipulation protocol, subjects breathed room air (normocapnia) or 6% inspired CO(2) (hypercapnia), or they hyperventilated to approximately 25 mm Hg P(ET)CO(2) (hypocapnia). In the LBNP protocol, subjects experienced 10 minutes each of -20 and -40 mm Hg lower body suction. CFV and diameter of the MCA were measured by transcranial Doppler and MRI, respectively, during the experimental protocols. RESULTS: Compared with normocapnia, hypercapnia produced increases in both P(ET)CO(2) (from 36+/-3 to 40+/-4 mm Hg, P CONCLUSIONS: Under the conditions of this study, changes in MCA diameter were not detected. Therefore, we conclude that relative changes in CFV were representative of changes in CBF during the physiological stimuli of moderate LBNP or changes in P(ET)CO(2)

Using EMCS Data to Document and Improve Air Handler Performance

Traditionally, energy monitoring and control systems (EMCS) have been used, as the name implies, to monitor and control heating, ventilating and air conditioning systems, however, this paper will identify other benefits of an EMCS. Recording EMCS data on a periodic basis, typically once an hour, and analyzing it using a commercial off the shelf database program has proven to be an effective method to improve and document indoor air quality, energy savings; and provide continuous controls commissioning and performance diagnostics. Identification of system problems is the key to having an efficient and reliable EMCS. Once identified they can be scheduled to be repaired and system integrity will be maintained. Specific diagnostic and functionality programming include: Identifying leaking heating and cooling control valves Identifying simultaneous heating and cooling operation Identifying proper air side economizer operation Identifying faulty components Identifying cooling and heating system problems Calculating ventilation rates Calculating energy wastes and savings Finally, using EMCS data in the non-traditional manner has saved thousands of dollars in operation and maintenance costs by providing a hands-off "tool" to diagnose air handler performance

X-ray scattering study of two length scales in the critical fluctuations of CuGeO3

The critical fluctuations of CuGeO$_3$ have been measured by synchrotron x-ray scattering, and two length scales are clearly observed. The ratio between the two length scales is found to be significantly different along the $a$ axis, with the $a$ axis along the surface normal direction. We believe that such a directional preference is a clear sign that surface random strains, especially those caused by dislocations, are the origin of the long length scale fluctuations.Comment: 5 pages, 4 figures, submitted to PR

Comparing the MRI Appearance of the Lymph Nodes and Spleen in Wild-Type and Immuno-Deficient Mouse Strains

The goal of this study was to investigate the normal MRI appearance of lymphoid organs in immuno-competent and immuno-deficient mice commonly used in research. Four mice from each of four different mouse strains (nude, NOG, C57BL/6, CB-17 SCID (SCID)) were imaged weekly for one month. Images were acquired with a 3D balanced steady state free precession (bSSFP) sequence. The volume of the lymph nodes and spleens were measured from MR images. In images of nude and SCID mice, lymph nodes sometimes contained a hyperintense region visible on MRI images. Volumes of the nodes were highly variable in nude mice. Nodes in SCID mice were smaller than in nude or C57Bl/6 mice (p<0.0001). Lymph node volumes changed slightly over time in all strains. The spleens of C57Bl/6 and nude mice were similar in size and appearance. Spleens of SCID and NOG mice were significantly smaller (p<0.0001) and abnormal in appearance. The MRI appearance of the normal lymph nodes and spleen varies considerably in the various mouse strains examined in this study. This is important to recognize in order to avoid the misinterpretation of MRI findings as abnormal when these strains are used in MRI imaging studies
