Blurring the boundaries? Supporting students and staff within an online learning environment
The inclusion of online learning technologies into the higher education (HE) curriculum is frequently associated with the design and development of new models of learning. One could argue that e-learning even demands a reconfiguration of traditional methods of learning and teaching. One of the key elements of this transformational process is flexibility. This paper considers a number of aspects relating to the flexibility inherent within models of online learning and the potential impact of this on support structures. City University, London, is used as a case study to provide examples of online practice which support strategies outlined here. A number of models of online learning are used at the University to provide evidence of the variation in modes of support and illustrate the different needs of both students and staff when using these forms of learning. What is apparent through this discussion is that to provide effective support for online learners, whether students or staff, clear and solid structures need to be put in place to assist with the creation of an online community

Partners with clinical practice: Evaluating the student and staff experiences of on-line continuing professional development for qualified nephrology practitioners
The inclusion of online learning technologies into the higher education (HE) curriculum is frequently associated with the design and development of new models of learning. One could argue that e-learning even demands a reconfiguration of traditional methods of learning and teaching. However, this transformation in pedagogic methodology does not just impact on lecturers and teachers alone. Online learning has āpervasive impacts and changes in other HE functionsā (HEFCE, p.2). Thus, e-learning is a transformational process that posits new challenges for staff and students, both in educational methods and support.
Many political, clinical, financial and social influences impact on registered health professionalsā ability to continue their professional development. This is particularly pertinent in the delivery of nephrology care.
In order to evaluate the programme that has now run for 2 years in the context of this institution, evaluative research methodology sought to explore the experiences of the staff and students involved. Qualitative data was collected from the students and a reflective framework was used to form the basis of a focus group for the staff.
This paper will present how a virtual learning environment (VLE) was developed utilising the pedagogic framework of solution-focused learning. It will demonstrate evaluation of the studentsā experiences compared to their traditional classroom-learning counterparts, and highlight the reflections of staff developers as they moved into new roles and developed different aspects of their present roles within a traditional HE context
Some studies on the behavior of W-RE thermocouple materials at high temperatures
Bare 0.25 mm diameter W-Re alloy thermoelements (W, W-3% Re, W-5% Re and W-25%) and BeO-insulated W-3% Re and W-25% Re thermoelements were examined for metallurgical, chemical and thermal emf changes after testing for periods up to 1000 hours at temperatures principally in the range 2000 to 2400 K. Environments for the tests consisted of high purity argon, hydrogen, helium or nitrogen gases. Commercially obtained bare-wire thermoelements typically exhibited a shift in their emf-temperature relationship upon initial exposure. The shift was completed by thermally aging the W-3% Re thermoelement for 1 hour and the W-25% Re thermoelement for 2 minutes at 2400 K in argon or hydrogen. Aged thermoelements experienced no appreciable drift with subsequent exposure at 2400 K in the gaseous environments. The chemically doped W3% Re thermoelement retained a small-grained structure for exposure in excess of 50 hours at 2400 K. BeO-insulated thermoelement assemblies showed varied behavior that depended upon the method of exposure. However, when the assemblies were heated in a furnace, no serious material incompatibility problems were found if the materials were given prior thermal treatments. Thermocouples, assembled from aged W-3% Re and W-25% Re thermoelements and degassed sintered BeO insulators, exhibited a drift of only 2 to 3 K during exposure in argon at 2070 K for 1029 hours

Questionnaires
The aims of this chapter are to present the potential uses of questionnaires and the principles involved in developing an effective and valid questionnaire. It will consider some of the issues involved with the effective development and use of questionnaires as a research tool, their administration and ethical considerations. The information provided in this chapter is not set out to be definitive, but rather, it is presented as an introduction in the development and use of questionnaires in health and physical activity research.
Depending on the intended research methods, the reader may wish to read this chapter alongside those on surveys, focus groups and questionnaires, as much of the information presented in these chapters relates and informs the others to provide a more comprehensive coverage. These chapters have been presented in this way to provide an informative coverage of the topic without excessive duplication and repetition of material
Does Monetary Policy Help Least Those Who Need It Most?
We estimate the impact of U.S. monetary policy on the cross-sectional distribution of state economic activity for a 35-year panel. Our results indicate that the effects of policy have a significant history dependence, in that relatively slow growth regions contract more following contractionarymonetary shocks. Moreover, policy is asymmetric, in that expansionary shocks have less of a beneficial impact upon relatively slow growth areas. As a result, we conclude that monetary policy on average widens the dispersion of growth rates among U.S. states, and those locations initially at the low end of the cross-sectional distribution benefit least from any given change inmonetary policy.Monetary policy, asymmetric effects, state dependence, regional business cycles
High reliability sheathed, beryllia insulated, tungsten-rhenium alloy thermocouple assemblies; their fabrication and EMF stability
Tantalum sheathed, BeO insulated, W-3% Re/W-25% Re thermocouple assemblies were fabricated and their emf drift determined during 2059 hours of exposure at 2073 K in a gaseous helium environment. The sheathed thermocouple assemblies were constructed from aged thermoelements, specially heat-treated BeO insulators, and specially cleaned and etched tantalum sheaths. Their thermal emf drifts ranged from the equivalent of only -0.3 to -0.8 K drift per 1000 hours of exposure at 2073 K. No evidence of any gross chemical attack or degradation of the component materials was found. The emf drift and material behavior of some unsheathed, BeO insulated, W-3% Re/W-25% Re thermocouples at 2250 and 2400 K were also determined. Unsheathed thermocouples tested in an argon environment at 2250 K for 1100 hours and at 2400 K for 307 hours exhibited changes in thermal emf that typically ranged from the equivalent of a few degrees K to as much as +11 K. Post-test examinations of these thermocouples revealed some undesirable material degradation and interaction which included erosion of the BeO insulators and contamination of the thermoelements by tantalum from the tantalum blackbody enclosure in which the thermocouples were contained

Physical activity barriers in the workplace : an exploration of factors contributing to non-participation in a UK workplace physical activity intervention
Purposeā The purpose of this paper is to explore factors contributing to non-participation in a workplace physical activity (PA) intervention in a large UK call centre.
Design/methodology/approach ā In total, 16 inactive individuals (nine male/seven female), aged 27Ā±9 years, who had not taken part in the intervention were interviewed to explore their perceptions of PA, the intervention and factors which contributed to their non-participation. Transcripts were analysed using thematic analysis.
Findings ā Six superordinate themes were identified: self-efficacy for exercise; attitudes towards PA; lack of time and energy; facilities and the physical environment; response to the PA programme and PA culture. Barriers occurred at multiple levels of influence, and support the use of ecological or multilevel models to help guide future programme design/delivery.
Research limitations/implications ā The 16 participants were not selected to be representative of the workplace gender or structure. Future intentions relating to PA participation were not considered and participants may have withheld negative opinions about the workplace or intervention despite use of an external researcher.
Practical implications ā In this group of employees education about the importance of PA for young adults and providing opportunities to gain social benefits from PA would increase perceived benefits and reduce perceived costs of PA. Workplace cultural norms with respect to PA must also be addressed to create a shift in PA participation.
Originality/value ā Employeesā reasons for non-participation in workplace interventions remain poorly understood and infrequently studied. The study considers a relatively under-studied population of employed young adults, providing practical recommendations for future interventions
No differences between beetroot juice and placebo on competitive 5-km running performance: A double-blind, placebo-controlled trial
We examined the effect of beetroot juice on endurance running performance in āreal-worldā competitive settings. One-hundred recreational runners (54% male; mean Ā± standard deviation, age = 33.3 Ā± 12.3 years, training history = 11.9 Ā± 8.1 years, hours per week training = 5.9 Ā± 3.5) completed a quasi-randomised, double-blind, placebo-controlled study of 5-km competitive time-trials. Participants performed four trials separated by one week in the order of pre-baseline, two experimental, and one post-baseline. Experimental trials consisted of the administration of 70-mL nitrate rich beetroot juice (containing ~4.1 mmol of nitrate, Beet It SportĀ®) or nitrate depleted placebo (containing ~0.04 mmol of nitrate, Beet It SportĀ®) 2.5 hours prior to time-trials. Time to complete 5-km was recorded for each trial. No differences were shown between pre- and post-baseline (P = 0.128, CV = 2.66%). The average of these two trials is therefore used as baseline. Compared to baseline, participants ran faster with beetroot juice (mean differences = 22.2 Ā± 5.0 s, P < 0.001, d = 0.08) and placebo (22.9 Ā± 4.5 s, P < 0.001, d = 0.09). No differences in times were shown between beetroot juice or placebo (0.8 Ā± 5.7 s, P < 0.875, d = 0.00). These results indicate that an acute dose of beetroot juice does not improve competitive 5-km time-trial performance in recreational runners compared to placebo
