This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m²) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.  相似文献

Virtual action learning: a pilot in building leadership capacity     

Phil Radcliff 《Action Learning: Research and Practice》2017,14(1):72-82

This account of practice encompasses a pilot virtual action learning programme with a small group of learners. This was an 18-month extension to the one-week Leadership Open Programme that the participants had previously completed at the Business School. It includes insights from an evaluation study completed in early 2016. It considers in particular the following issues: the structuring of a virtual event; the significance of maintaining continuity of learning; the need for commonality of reference points about leadership in order to enhance it; the selection of problems by participants; whether leadership development itself is a ‘wicked problem’ and the role and skills required of the tutor to add value to the learning experience. Amongst other benefits, the participants found the chance to build relationships broke down the loneliness of leadership and greatly enhanced their learning. These issues will be explored further in a review planned for early 2017.  相似文献

Signaling functions of the second-order CS: Partial reinforcement during second-order conditioning of the pigeon’s keypeck     

Michael E. Rashotte  Beverly S. Marshall  Jeffrey M. O’Connell 《Learning & behavior》1981,9(2):253-260

The signaling function of the second-order CS (S2) was manipulated in second-order autoshaping by arranging a partial reinforcement schedule. S2 was paired with a well-conditioned first-order CS (SI) on a continuous reinforcement or a 25% reinforcement schedule in different groups. Schedule of reinforcement did not influence the number of S2-S1 pairings required to establish keypecking to S2. However, in the postacquisition sessions, responding to S2 was initially weaker but persisted for many more sessions on the 25% schedule than on the 100% schedule. The data indicate that S2-S1 pairings are responsible both for the acquisition of second-order keypecking to S2 and for the subsequent conversion of S2 into an inhibitory stimulus.  相似文献   

Examination of a learning style topology     

Jon C. Marshall 《Research in higher education》1987,26(4):417-429

This study provides an initial examination of a learning style topology through the comparison of information processing and instructional preference toponymies. It was hypothesized that learning style modes would be discernible within each of these toponymies and that the toponymies would demonstrate orthogonality. Data analyzed for 429 university students supported these hypotheses.  相似文献

Human causality judgments and response rates on DRL and DRH schedules of reinforcement     

Reed P 《Learning & behavior》2003,31(2):205-211

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.  相似文献
