This study reports an intervention to initiate environmental learning and facilitate pro-environmental behaviour. The purpose was to examine the impact of ambient learning displays on energy consumption and conservation at the workplace, more specifically the evaluation of learning outcome and behaviour change. Using a quasi-experimental design, the empirical study was conducted among employees working at a university campus. For the experimental treatments, ambient learning display prototypes were varied on two design dimensions, namely representational fidelity and notification level. The results do not provide clear evidence that the design of the displays influences learning outcome or that the displays lead to pro-environmental behaviour change. Nevertheless, the sole deployment of the display prototypes eased the comprehension of the information provided and lowered the need for additional information. Thus, ambient learning displays provide a promising framework in the context of environmental learning and beyond.  相似文献

In search of key-performance predictors in sailing, we examined to what degree visual search, movement behaviour and boat control contribute to skilled performance while rounding the windward mark. To this end, we analysed 62 windward mark roundings sailed without opponents and 40 windward mark roundings sailed with opponents while competing in small regattas. Across conditions, results revealed that better performances were related to gazing more to the tangent point during the actual rounding. More specifically, in the condition without opponents, skilled performance was associated with gazing more outside the dinghy during the actual rounding, while in the condition with opponents, superior performance was related to gazing less outside the dinghy. With respect to movement behaviour, superior performance was associated with the release of the trimming lines close to rounding the mark. In addition, better performances were related to approaching the mark with little heel, yet heeling the boat more to the windward side when being close to the mark. Potential implications for practice are suggested for each phase of the windward mark rounding.  相似文献

This paper describes experiments carried out to determine the influence of dovetailed cross beams on the dimensional stability of a panel painting from the Middle Ages. Besides a serious cup (transverse distortion), the panel featured an unusual longitudinal distortion, a bow, mostly originating from bending in the proximity of the middle cross beam. Because of its localized occurrence, bending appeared to be caused by the crossbeam somehow pushing on the walls of its channel. Thanks to the cooperation offered by the curator and the restorer, some non-damaging tests were performed to measure the distortions of the panel, with and without the cross beams, after conditioning it in different climates. Processing and analysis of the measurement results demonstrated that the bow of the panel increases as the wood moisture content decreases. This led to the conclusion that the bow is actually produced by forces exerted by the cross beam along the panel's length, according to a mechanism named thrust transformation. By this mechanism the cross beam partly transforms the panel's tendency towards cupping, into a bow distortion.  相似文献

Aaron the Moor from Titus Andronicus and Ratonhnhaké:ton from Assassin’s Creed III are each aiding in a war against an international superpower, and both characters are plotting ways to advance and improve their respective culture. Aaron is seen as the villain and the antagonist, whereas Ratonhnhaké:ton is seen as an individual who fights for freedom. However, once both characters’ usefulness is exhausted, they are easily characterized as the Other and lose whatever benefits they may have earned. They are tossed aside by the factions they are trying to help. Even though Assassin’s Creed III is a video game, the same issues of colonialism and imperialism can be investigated in this 21st-century genre as in Shakespeare’s play.  相似文献

Adolescents who work while attending school are reported to sleep less than those who do not. This study aimed to identify factors associated with short sleep duration in students who work during the school year. A cross‐sectional survey aiming to describe working conditions and occupational safety and health was completed by representative samples of Quebec high school students aged 12–19 years from three administrative regions (n = 3,871). A multiple stepwise regression analysis was performed with sleep duration as the dependent variable, and sociodemographic, school, occupational, and health factors as potential explanatory variables. Significant factors associated with shorter sleep duration were later bedtimes (p < .001), shorter weekend oversleep (p < .001), higher physical work factors related to handling efforts (p < .001), and female gender (p < .01). Addressing work conditions of student workers may help prevent sleep deprivation. Special efforts should also target girls combining work and study.  相似文献

This study examines the effect of antitrust regulation of patent consolidation on the development of follow-on innovations. Our reconciliation of the various strains of literature hypothesizes that in sectors where cumulative innovation is crucial to firms’ market operations, a firm that consolidates patents for substituting technologies for its already-possessed technologies discourages market competitions and follow-on innovation by competitors. In this case, antitrust regulation of patent consolidation is anticipated to positively affect competitors’ follow-on innovation. We empirically test this hypothesis with the case of the US Department of Justice's regulation of Novell's software patent transfers to four large proprietary software companies (i.e., Microsoft, Oracle, EMC, and Apple) in 2011. Our analyses using US patent, trademark, and copyright data have found evidence corroborating our hypothesis. Our research provides policy and scholarly implications regarding how antitrust law can be a complementary institution to the patent law for promoting innovation.  相似文献

In this paper, we explore the work life of a scholar new to academia in her methods of leading informally. We discuss five vignettes that offer moments of learning and reflection, including reducing performance anxiety, privileging financial accountability, the rise of the virtual world, the impact of silence, and the potential for confrontation to strengthen working relationships. We offer suggestions as to how contemporary leaders may adapt to the freedom that artful action offers.  相似文献
