Utilising the virtual learning environment to encourage faculty reflection and improve the student learning experience
Student evaluations of teaching (SETs) are the most frequent form of faculty performance in the classroom, though they tend to be used as summative rather than formative evaluations. In this chapter, a project involving the use of a virtual learning environment for formative, weekly SETs is explored from both the student and faculty point of view at a rural university college in the United Kingdom. This project encouraged student participation in creating the learning environment and faculty reflection on how to improve the student experience. From the student perspective, the weekly anonymous evaluations were useful for providing feedback; however, students tended to only respond if they were not satisfied with the faculty member. The exception to this was that some students were more motivated to complete the evaluation forms if they believed the faculty member was utilising their feedback. From the faculty perspective, the feedback was not as detailed as they had expected, and some questioned whether it was worth the effort of conducting formative evaluations if the response rate was so low. Others used the feedback for reflective purposes, and it was found that those that reflected on their work at higher levels tended to receive a greater year-on-year increase in their end of year teaching evaluations.<br /
Comparison of the Effects of Ice and 3.5% Menthol Gel on Blood Flow and Muscle Strength of the Lower Arm
Context: Soft-tissue injuries are commonly treated with ice or menthol gels. Few studies have compared the effects of these treatments on blood flow and muscle strength. Objective: To compare blood flow and muscle strength in the forearm after an application of ice or menthol gel or no treatment. Design: Repeated measures design in which blood-flow and muscle-strength data were collected from subjects under 3 treatment conditions. Setting: Exercise physiology laboratory. Participants: 17 healthy adults with no impediment to the blood flow or strength in their right arm, recruited through word of mouth. Intervention: Three separate treatment conditions were randomly applied topically to the right forearm: no treatment, 0.5 kg of ice, or 3.5 mL of 3.5% menthol gel. To avoid injury ice was only applied for 20 min. Main Outcome Measures: At each data-collection session blood flow (mL/min) of the right radial artery was determined at baseline before any treatment and then at 5, 10, 15, and 20 min after treatment using Doppler ultrasound. Muscle strength was assessed as maximum isokinetic flexion and extension of the wrist at 30°/s 20, 25, and 30 min after treatment. Results: The menthol gel reduced (–42%, P \u3c .05) blood flow in the radial artery 5 min after application but not at 10, 15, or 20 min after application. Ice reduced (–48%, P \u3c .05) blood flow in the radial artery only after 20 min of application. After 15 min of the control condition blood flow increased (83%, P \u3c .05) from baseline measures. After the removal of ice, wrist-extension strength did not increase per repeated strength assessment as it did during the control condition (9–11%, P \u3c .05) and menthol-gel intervention (8%, P \u3c .05). Conclusions: Menthol has a fast-acting, short-lived effect of reducing blood flow. Ice reduces blood flow after a prolonged duration. Muscle strength appears to be inhibited after ice application
First record of Pseudohaida rothi Hatch (Coleoptera: Staphylinidae: Omaliinae) from Canada
Pseudohaida rothi Hatch is reported for the first time from Canada from an old-growth, temperate rain forest on Vancouver Island, B.C. Records of other rare species of the subfamily Omaliinae are given together with a brief discussion of the importance of the remaining intact old-growth forests in preserving the biodiversity contained in the forest regions of Canada
Carrington: Community of difference?
Newcastle is a city redolent with images. Perhaps the most dominant of these is of a male industrial working environment deriving from the days of the \u27coally seaport\u27, while other aspects of its identity, such as the female and the Aboriginal, are suppressed and obscured (Dunn et al., 1995). Another recurrent image is of profound community, of solidaritty. This is evident in the \u27Our Town\u27 epithet applied to numerous local businesses. 5uch an image is portrayed in the cartoon by Eggleston, where the SS Newcastle is under siege from economic, political and physical forces, where the (all male) inhabitants, clinging together in adversity, are ignored by the Canberra rescue service. Such imagery is demonstrative of community but it is largely negative. The community is parochial, defensive and whinging, complaining of discrimination against it by \u27them\u27, the authorities in Sydney and Canberra, yet expecting \u27them\u27 to be a saviour when in distress. It is aJso a commrmity which is partial andd exclusionary, consisting solely of the Anglo males in their sinking industrial ship (Dunn, 1992)

Effects of cropping, smoothing, triangle count, and mesh resolution on 6 dental topographic metrics
Dental topography is a widely used method for quantifying dental morphology and inferring dietary ecology in animals. Differences in methodology have brought into question the comparability of different studies. Using primate mandibular second molars, we investigated the effects of mesh preparation parameters smoothing, cropping, and triangle count/mesh resolution (herein, resolution) on six topographic variables (Dirichlet normal energy, DNE; orientation patch count rotated, OPCR; relief index, RFI; ambient occlusion, portion de ciel visible, PCV; enamel surface area, SA; tooth size) to determine the effects of smoothing, cropping, and triangle count/resolution on topographic values and the relationship between these values and diet. All topographic metrics are sensitive to smoothing, cropping method,
and triangle count/resolution. In general, smoothing decreased DNE, OPCR, RFI, and SA,increased PCV, and had no predictable effect on tooth size. Relative to the basin cut off (BCO) cropping method, the entire enamel cap (EEC) method increased RFI, SA, and size, and had no predictable effect on DNE and OPCR. Smoothing and cropping affected DNE/
OPCR and surfaces with low triangle counts more than other metrics and surfaces with high triangle counts. There was a positive correlation between DNE/OPCR and triangle count/
resolution, and the rate of increase was weakly correlated to diet. PCV tended to converge or decrease with increases in triangle count/resolution, and RFI, SA, and size converged.
Finally, there appears to be no optimal triangle count or resolution for predicting diet from this sample, and constant triangle count appeared to perform better than constant resolution for predicting diet
The Relationship Between Aerobic and Anaerobic Performance in Recreational Runners
International Journal of Exercise Science 9(5): 625-634, 2016. Research has indicated that combined aerobic and anaerobic training (concurrent training) may improve aerobic performance greater than aerobic training alone. The purpose of this investigation was to establish any associations between aerobic and anaerobic performance. Eleven participants (n = 11, age = 34.1 ± 13 years, VO2max = 58.4 ± 7.8) volunteered for this study. Participants were asked for endurance training experience (4.7 ± 3.7 years) and resistance training experience (4.1 ± 4.6 years). To meet training status, participants were to have a VO2max in the 80th percentile as per ACSM guidelines. The Bruce treadmill test was used to measure aerobic performance. In order to measure anaerobic performance, several tests were completed utilizing a force platform. A Pearson Product R Correlation Coefficient was calculated to determine correlations between variables. The results show significant correlation between VO2max and RFD (r = 0.68). Further analyses utilizing Cohen’s effect size indicated a strong association between VO2max and peak force, as well as running efficiency and peak power, relative peak power, and power endurance. These results indicate an existing possibility that anaerobic performance measures such as RFD may have a positive relationship with aerobic performance measures such as VO2max. Therefore, it may be beneficial to integrate specific training components which focus on improving RFD as a method of improving running performance
