teachers’ sense of efficacy belief has been introduced as a context-specific construct, but the related literature is not clear on this specificity. this study was an attempt to show how contextual factors influence efficacy beliefs among english language teachers. to this end, thirty iranian efl teachers working in both school and private institute contexts were chosen as the participants to r...

the muslim scholars, philologists and rhetoricians are unanimous that the eloquence of the holy prophet, peace be upon him and his household, is unparalleled and there is nothing like his style and discourse. to put it in other words, the speech of the prophet is beneath the speech of god but above that of people in that it gathers the most comprehensive discourses and wonders of eloquence and ...

on-farm management practices with the aim of improving water use efficiency (wue) are among the practical ways of overcoming the water scarcity problem. this study aims to investigate ways of implementing agricultural water management in abarkouh region, yazd province, which mainly deals with problems such as water scarcity and salinity of soil and water resources. to this end, the resulting sc...

Recent events, news articles in the popular press, and research outside the field of economics have raised alarming questions about the sufficiency of global freshwater supplies and the potentially devastating impacts of current and future water shortages. For example, the 2008 Beijing Olympics drew attention to the problems of pollution and water shortages in China, where massive infrastructur...

Operating under limited resources poses significant demands on the cognitive system. Here we demonstrate that people under time scarcity failed to detect time-saving cues as they occur in the environment (Experiment 1a). These time-saving cues, if noticed, would have saved time for the time-poor participants. Moreover, the visuospatial proximity of the time-saving cues to the focal task determi...

Despite increasing focus on data publication and discovery in materials science and related fields, the global view of materials data is highly sparse. This sparsity encourages training models on the union of multiple datasets, but simple unions can prove problematic as (ostensibly) equivalent properties may be measured or computed differently depending on the data source. These hidden contextu...

A WWF/Oxfam discussion paper-Alex Evans Purpose This discussion paper is intended to contribute to the evolving debate on the links between resource scarcity and international development, in particular by focusing on the issues of equity and " fair shares " for poor people and poor countries that arise in the context of resource limits and environmental boundaries. It provides a short overview...

We describe a code transformation technique that, given code for a vector function F , produces code suitable for computing collections of Jacobian-vector products F (x)ẋ or Jacobiantranspose-vector products F (x) ȳ. Exploitation of scarcity a measure of the degrees of freedom in the Jacobian matrix means solving a combinatorial optimization problem that is believed to be hard. Our heuristics t...

The issue of the allocation of resources in health care is here to stay. The goal of this study was to explore the views of physicians on several topics that have arisen in the debate on the allocation of scarce resources and to compare these with the views of policy makers. We asked physicians (oncologists, cardiologists, and nursing home physicians) and policy makers to participate in an inte...
