In repeated measures studies how observations change over time is often of prime interest. Modelling this time effect in the context of discrimination, is the objective of this article. We study the problem of classification with multiple q-variate observations with time effect on each individual. The covariance matrices as well as mean vectors are mordelled respectively to accommodate the correlation between the successive repeated measures and to describe the time effects. Computation schemes for maximum likelihood estimation of required population parameters are provided.

People with Parkinson disease (PD) demonstrate improvements in motor function following group tango classes, but report long commutes as a barrier to participation. To increase access, we investigated a telerehabilitation approach to group tango instruction. Twenty-six people with mild-to-moderate PD were assigned based on commute distance to either the telerehabilitation group (Telerehab) or an in-person instruction group (In-person). Both groups followed the same twice-weekly, 12-week curriculum with the same instructor. Feasibility metrics were participant retention, attendance and adverse events. Outcomes assessed were balance, PD motor sign severity and gait. Participant retention was 85% in both groups. Attendance was 87% in the Telerehab group and 84% in the In-person group. No adverse events occurred. Balance and motor sign severity improved significantly over time ( p < 0.001) in both groups, with no significant group × time effects. Gait did not significantly change. Since a priori feasibility criteria were met or exceeded, and there were no notable outcome differences between the two instruction approaches, this pilot study suggests a telerehabilitation approach to group tango class for people with PD is feasible and may have similar outcomes to in-person instruction.

New Discovery

With the implementation of discovery systems, cataloging maintenance and authority control activities need to be re-evaluated. The online survey product Qualtrics™1 was used to solicit completion of only one survey per library (275) who has adopted a discovery system. Questions about changes in tasks and staffing before and after implementation of commercial discovery systems (AquaBrowser®2, EBSCO Discovery Services™3, Encore™4, Primo®5, Summon™6, and WorldCat®7 Local) were central to the survey. Ninety-eight libraries responded with usable surveys (36% response rate). Results indicated that there were no significant differences between maintenance and authority control tasks before and after discovery implementation. Although the length of time since implementation compared to workflow changes indicates that change decreases over time, effects of the discovery system may not yet have reached maintenance and authority control staff. Cataloging staff were also surveyed to measure their awareness on how local holdings in the new discovery environment are presented to the public. Results also indicate that significantly more survey respondents anticipate that their legacy OPAC will persist alongside their discovery system.

To determine changes in appetite, affect and cortisol in response to an acute bout of resistance exercise (RE) the morning after consuming whey (WP) and casein (CP) protein and a non-caloric placebo (PLA) consumed pre-sleep, 14 active men (n = 5) and women (n = 9) consumed a single dose of 24 g WP, 48 g WP, 24 g CP, 48 g CP, or PLA 30 min pre-sleep. Prior to and immediately after RE, appetite, affect and cortisol were assessed. Significant time effects were observed for Energetic Arousal and Tense Arousal (p = 0.017) and Feeling Scale and Felt Arousal Scale (p < 0.001). Appetite did not change over time or condition. Cortisol levels increased after RE (p = 0.007). Pre-RE, Tense Arousal was correlated with hunger (r = 0.25, p = 0.047) and desire to eat (r = 0.35, p = 0.005). Post-RE, cortisol was found to be significantly related to Feeling Scale (r = 0.32, p = 0.018), Felt Arousal Scale (r = 0.33, p = 0.015) and Energetic Arousal (r = 0.32, p = 0.018). Varying doses of WP and CP pre-sleep did not have an effect on morning appetite and cortisol, but cortisol was found to be related to affect and appetite.

Abstract Long-term settlement induced by tunnelling in soft cohesive subsoil is rarely considered as a subject for research despite substantial evidence that it increases considerably after construction. The paper aims to investigate the time effects of tunnelling with an earth pressure balance (EPB) shield by means of analysing subsoil deformation with the most up-to-date numerical tool. A three-dimensional numerical model with a detailed description of the geometrical and mechanical characteristics of the tunnelling process and the various materials involved was built. The computational model validated on a real-case was then used to simulate tunnelling in different groundwater conditions prior to construction. That was followed by a simulation of groundwater drawdown conditions after tunnelling with impermeable and permeable tunnel linings. The calculations show the development of the settlement over time in different groundwater conditions together with the significant influence of the permeability of the tunnel.
