AbstractChildren’s connection to nature (CTN) is declining with each generation, a concerning trend given that CTN is positively linked to wellbeing and environmentalism. A primary cause of this decline is that twenty-first-century youth engage with screens for several hours each day, which to a large extent replaces nature-based play. Researchers have proposed that this change represents a transition in human orientation, particularly in Westernized societies, from nature (biophilia) to digital media (videophilia). Interventions promoting nature-based play must acknowledge digital-media use as a competing leisure pursuit, but the literature presents little guidance for designing programs that will attract young people who are more oriented toward digital media than nature. Drawing on a wide breadth of research, we address this gap through (1) exploring the implications of videophilia for nature-based programming and (2) summarizing recommendations from a narrative literature review for designing interventions that appeal to digital-media-oriented youth. 相似文献

In previous work it was established that the U.K. tractor industry was characterised by a high degree of technical change and that this was brought about by a process of more or less continuous incremental innovation. What was lacking was an analysis of how much technical change had been introduced and an indication of the role played by technical change in determining the performance of the U.K. tractor industry internationally. This paper concludes that on the average technical change in the industry had increased by as much as 150 percent during the years 1959–1977, though there is some indication that the rate of change might now be slowing somewhat.In order to determine the relative importance of technical change a method was developed to operationalise the distinction between price and non-price competition as well as the idea of intrinsic (technical) and associative (non-technical) factors as constituents of the latter. Based on cross-sectional data for the year 1978, it has been possible to show that British manufacturers tend to produce moderately priced tractors of low to medium technical sophistication: that German manufacturers produced the most technically sophisticated tractors; that the Italian manufacturers are not generally more sophisticated, technically, than the British producers except with respect to their development of four-wheel drive; and that COMECON-based producers combine a very low price with some degree of technical sophistication. Finally, it has been possible to show that the tractors with the highest sales are among the less sophisticated in each of the power ranges investigated and that new entrants used technical sophistication as an element of their entry strategy. The answer to the question of what allows the market leader to be market leader required the development of measures for associative non-price factors, such as the availability of a dealer network brand loyalty, resale prices of tractor models, etc. By performing a regression analysis on these measures along with previously derived measures of quality-adjusted price and relative technical sophistication it has been possible to show that market leadership is achieved as a result of a balance of a number of factors, the most important of which are the size of the dealer network, warrants cost, advertising, technical sophistication and price. 相似文献

Integrating environmental sustainability into universities 总被引：1，自引：0，他引：1
Universities play a fundamental role in addressing global environmental challenges as their education, research and community involvement can produce long-lasting environmental effects and societal change. By demonstrating best practice in their operations, research and teaching, universities have both multiple and multiplier effects on society. For universities to comprehensively address sustainability, a ‘learning for sustainability’ approach needs to be embedded across every aspect of institutional operations in a synergistic way. Using semi-structured interviews, this research explored the factors that influence the integration of sustainability into the operations, teaching and research activities of universities in Australia and England. The research found that individuals, committed to the goal of a more sustainable world, play a vital role in the success of integrating environmental sustainability into universities. The factors critical to enabling universities to undertake the transformational changes necessary to embed environmental sustainability into all university areas included: a strong policy environment, resourcing of strategies, and encouragement of leaders and environmental sustainability advocates. Educating and building the awareness of university staff of the importance of environmental sustainability to future generations was key to a successful strategy. 相似文献

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

The publication of Trading in Futures and When Schools Compete helped give empirical support to the view that choice policies increased differences between schools. However, dispute about this research and changes in policy mean that our understanding of the impact of school choice policies in New Zealand remains partial. This paper aims to address continued uncertainty about the impact of school choice policies in New Zealand. It presents the results of a study that drew upon qualitative data gathered in interviews with school principals and on administrative data on the enrolment patterns in the same competition space explored by the Trading in Futures research. The data show that periods of greatest instability in enrolments occurred around the time of change in regulations. 相似文献

This paper unearths how primary school children experience and can complement the Australian HPE curriculum within three unique school ground equipment scenarios that include an ‘empty’, ‘loose parts’ and a ‘traditional’ school ground context. Using direct observation, 490 scans were undertaken of the school grounds over five days. Field note observations recorded children's HPE learning experiences according to the curriculum, and predominant physical activity types and intensities were recorded. Implementing a variety of school ground equipment provisions was revealed to be important compared to the ‘empty’ school ground context for primary school children to meet HPE curriculum objectives. 相似文献

In a second-order schedule, fixed-interval components were reinforced according to a variable-interval schedule. A brief stimulus accompanied the completion of each fixed interval. Brief-stimulus duration was varied across conditions from 0.5 to 8 sec. Patterning was greater the longer the duration of the stimulus. Additionally, exposure to relatively long brief-stimulus durations enhanced patterning upon reexposure to shorter brief-stimulus durations. 相似文献

Although Muslims have a significant presence at American universities, they are largely ignored by campus policies and resources and may find it difficult to reconcile their university experience with their religious values and practices. Using bicultural acculturation as a theoretical lens along with interviews and document analysis, this exploratory study of ten Muslim students at one university suggests that students have acquired the tools to successfully navigate membership in both American and Muslim cultural groups, evaluating each setting before invoking a particular identity. However, the acculturation process does not require any change by the institution. While participants described a need to adopt situationally-appropriate behaviors, they did not expect accommodation from the university or their peers. 相似文献
