The United States Holocaust Memorial Museum — A Dialogue with Memory     

James Ingo Freed 《Curator: The Museum Journal》1995,38(2):95-110

This article describes the author's personal/professional experience in designing the United States Holocaust Memorial Museum, a building that must “fit” in the context of the National Mall, express the spirit of the Holocaust, and become a permanent, living memorial. “The [building] did not pose the familiar problem of the container and the contained. This [must be] a building where the contained (the historical exhibition) works on the container (the architectural shell) and where the container has to join with the contained.”  相似文献   

The influence of short-term fixture congestion on position specific match running performance and external loading patterns in English professional soccer

The aim of the current study was to investigate positional specific physical performance and external load responses to short term fixture congestion in English professional soccer. A total of 515 match observations were categorised as G1: the first game in a week with >4 days following a previous game, G2: the second game in a week played <4 days since G1, and G3: the third game in a week played with <4 days between each of the previous games. Global positioning system and accelerometer-based metrics were partitioned into fifteen-minute epochs. These data were then analysed using a linear mixed model to assess both the within and between game positional differences. Total, low-intensity (<4.0 m·s^?1), medium-intensity (MID; 4.0–5.5 m·s^?1), and sprint distance (>7.0 m·s^?1) were significantly different across games. No between game positional differences were identified; however, within match position specific differences were observed for measures of MID and HID. No significant differences were evident for accelerometer derived metrics between games or across positions. The current data suggests that the use of fifteen minute within game epochs enables the detection of alterations in physical output during congested schedules. The observed within game positional differences has implications for player specific conditioning and squad rotation strategies.  相似文献

Predicting vertical ground reaction force during running using novel piezoresponsive sensors and accelerometry

ABSTRACT

Running is a common exercise with numerous health benefits. Vertical ground reaction force (vGRF) influences running injury risk and running performance. Measurement of vGRF during running is now primarily constrained to a laboratory setting. The purpose of this study was to evaluate a new approach to measuring vGRF during running. This approach can be used outside of the laboratory and involves running shoes instrumented with novel piezoresponsive sensors and a standard accelerometer. Thirty-one individuals ran at three different speeds on a force-instrumented treadmill while wearing the instrumented running shoes. vGRF was predicted using data collected from the instrumented shoes, and predicted vGRF were compared to vGRF measured via the treadmill. Per cent error of the resulting predictions varied depending upon the predicted vGRF characteristic. Per cent error was relatively low for predicted vGRF impulse (2–7%), active peak vGRF (3–7%), and ground contact time (3–6%), but relatively high for predicted vGRF load rates (22–29%). These errors should decrease with future iterations of the instrumented shoes and collection of additional data from a more diverse sample. The novel technology described herein might become a feasible way to collect large amounts of vGRF data outside of the traditional biomechanics laboratory.  相似文献   

A conducive environment? The role of need support in the higher education workplace and its effect on academics' experiences of research assessment in the UK     

Netta Weinstein  Jennifer A. Chubb  Geoffrey Haddock  James R. Wilsdon 《Higher Education Quarterly》2021,75(1):146-160

Little is known about how researchers in higher education institutions (HEIs) experience and respond to support received from their departments. The present study investigated how support for researchers' autonomy (choice and self‐expression), relatedness (through connections with colleagues) and competence (feeling effective in one's work) influenced their attitudes towards an external assessment of research. To do so, we surveyed 598 academics from four HEIs in the UK about their attitudes towards one such external assessment: the Research Excellence Framework (REF), a nationwide assessment of research quality and the subject of debate about research evaluation. Our findings, drawing on self‐determination theory, show that departments can shape responses to the REF: individuals whose psychological needs were supported by their academic departments held more positive, and less negative, attitudes towards the REF. This occurred both directly and indirectly through researchers' recognition that the REF had a more positive influence on their research activities and outputs.  相似文献   

Improving energy expenditure estimates from wearable devices: A machine learning approach

ABSTRACT

A means of quantifying continuous, free-living energy expenditure (EE) would advance the study of bioenergetics. The aim of this study was to apply a non-linear, machine learning algorithm (random forest) to predict minute level EE for a range of activities using acceleration, physiological signals (e.g., heart rate, body temperature, galvanic skin response), and participant characteristics (e.g., sex, age, height, weight, body composition) collected from wearable devices (Fitbit charge 2, Polar H7, SenseWear Armband Mini and Actigraph GT3-x) as potential inputs. By utilising a leave-one-out cross-validation approach in 59 subjects, we investigated the predictive accuracy in sedentary, ambulatory, household, and cycling activities compared to indirect calorimetry (Vyntus CPX). Over all activities, correlations of at least r = 0.85 were achieved by the models. Root mean squared error ranged from 1 to 1.37 METs and all overall models were statistically equivalent to the criterion measure. Significantly lower error was observed for Actigraph and Sensewear models, when compared to the manufacturer provided estimates of the Sensewear Armband (p < 0.05). A high degree of accuracy in EE estimation was achieved by applying non-linear models to wearable devices which may offer a means to capture the energy cost of free-living activities.  相似文献   

Cow's milk as a post-exercise recovery drink: implications for performance and health     

Lewis J. James  Emma J. Stevenson  Penny L. S. Rumbold  Carl J. Hulston 《European Journal of Sport Science》2019,19(1):40-48

Abstract

Post-exercise recovery is a multi-facetted process that will vary depending on the nature of the exercise, the time between exercise sessions and the goals of the exerciser. From a nutritional perspective, the main considerations are: (1) optimisation of muscle protein turnover; (2) glycogen resynthesis; (3) rehydration; (4) management of muscle soreness; (5) appropriate management of energy balance. Milk is approximately isotonic (osmolality of 280–290?mosmol/kg), and the mixture of high quality protein, carbohydrate, water and micronutrients (particularly sodium) make it uniquely suitable as a post-exercise recovery drink in many exercise scenarios. Research has shown that ingestion of milk post-exercise has the potential to beneficially impact both acute recovery and chronic training adaptation. Milk augments post-exercise muscle protein synthesis and rehydration, can contribute to post-exercise glycogen resynthesis, and attenuates post-exercise muscle soreness/function losses. For these aspects of recovery, milk is at least comparable and often out performs most commercially available recovery drinks, but is available at a fraction of the cost, making it a cheap and easy option to facilitate post-exercise recovery. Milk ingestion post-exercise has also been shown to attenuate subsequent energy intake and may lead to more favourable body composition changes with exercise training. This means that those exercising for weight management purposes might be able to beneficially influence post-exercise recovery, whilst maintaining the energy deficit created by exercise.  相似文献
