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

This study adds to the literature on household sector (HHS) innovation by investigating how user and professional designer teams differ in their ability to translate knowledge diversity into collective creative output. We test our hypotheses on a unique data set of more than 5,000 board game design projects conducted by either teams of professional game designers or by hobbyist (user) designers. Our study lends support for the notion that knowledge diversity is a double-edged sword that has opposing effects on the two dimensions of team creativity, novelty and usefulness. We argue and find that teams composed of self-rewarded users in the household sector are better able than teams of professionals to translate the informational benefits of knowledge diversity into novel concepts and game designs. Finally, we find that user teams are in general more likely to create truly creative (i.e. novel and useful) game designs. This particular result emphasizes the relevance of research on HHS innovation and shows that user designers from the HHS are able to conduct collective development work more effectively than teams of professional designers. 相似文献

We estimate the effect of R&D spillovers on sales realized by products new to the firm (imitation) and new to the market (innovation). It turns out that spillovers from rivals lead to more imitation, while input from customers and research institutions enhance original innovation. 相似文献

Zusammenfassung. Moderne Software-Entwicklungsumgebungen arbeiten mit einer Vielzahl von Editoren und Anzeigewerkzeugen, wobei der Informationsgehalt
mehrerer Fenster überlappen kann. Wenn nun irgendein Werkzeug Dokumente ?ndert, müssen alle betroffenen Anzeigen korrigiert
werden. Hierzu werden heute in mehrbenutzerf?higen, verteilten Software-Entwicklungsumgebungen überwiegend Kommunikationssysteme
wie z.B. ToolTalk™ eingesetzt. Diese verursachen einen relativ hohen Programmier- und Laufzeitaufwand und sind insofern unsicher,
als Anzeigewerkzeuge nicht von allen Ver?nderungen an den Daten informiert werden, u.a. von ?nderungen durch nicht integrierte
Werkzeuge. Dieses Papier stellt einen Benachrichtigungsmechanismus für Software-Entwicklungsumgebungen vor, der effizient,
leicht benutzbar und sicher ist, sowie seine Implementierung im Objektmanagementsystem H-PCTE.

International reports on environmental policy promote 'education for sustainable development' as an instrument for realising environmental awareness, values and attitudes consistent with the liberal concept of 'sustainable development'. In this paper the ethical and political-philosophical assumptions of (education for) sustainable development will be criticised. First, it will be argued that (Rawlsian) liberal ethics cannot include obligations towards future generations. Second, the commentary focuses on the economic perspective underlying this liberal framework, its anthropocentric bias and the hierarchical distinction between public and private spheres. Third, to offer a more adequate framework for environmental education, some fruitful ideas within neo-republicanism will be examined. 相似文献

Several recent ascertaining studies revealed a deep-rooted and almost irresistible tendency among 12–16-year old students
to improperly apply the linear or proportional model in word problems involving lengths, areas and volumes of similar plane
figures and solids. While these previous studies showed to what extent students' improper use of linear reasoning is affected
by different characteristics of the task, it remained largely unclear what aspects of their knowledge base are responsible
for the occurrence and strength of this phenomenon and how these aspects relate to other more general misconceptions and buggy
rules identified in the literature. This paper reports an in-depth investigation by means of individual semi-standardised
interviews aimed at analysing the thinking process underlying students' improper linear reasoning and how this process is
affected by their mathematical conceptions, beliefs and habits. During these interviews,students' solution processes were
revealed through a number of well-specified questions by the interviewer with respect to one single non-linear application
problem, as well as through their reactions to subsequent kinds of cognitive conflict. The interviews provided a lot of information
about the actual process of problem solving from students falling into the ‘linearity trap’ and the mechanism behind it. Although
some students seem to really ‘believe’ that quantities are always linked proportionally, their improper use of linearity often
results from superficial and intuitive reasoning, influenced by specific mathematical conceptions, habits and beliefs leading
to a deficient modelling process.

We investigate the use and knowledge of graphs in the context of a large industrial factory. We are particularly interested
in the question of “transparency”, a question that has been extensively considered in the general literature on tool use and,
more recently, by Michael Roth and his colleagues in the context of scientific work. Roth uses the notion of transparency
to characterise instances of graph use by highly educated scientists in cases where the context was familiar: the scientists
were able to read the situation “through” the graph. This paper explores the limits of the validity of the transparency metaphor.
We present two vignettes of actual graph use by a factory worker, and contrast his actions and knowledge with that of a highly
qualified process engineer working on the same production line. We note that in neither case the graphs were transparent.
We argue that a fuller account that describes a spectrum of transparency is needed, and we seek to achieve this by adopting
some elements of a semiotic approach that enhance a strictly activity-theoretical view. 相似文献
