Sustainability Strategies: When Does it Pay to be Green?
By analysing the rationales for sustainability strategies, this book addresses a timely question for managers, academics and MBAs: â€œwhen does it pay to be green?â€� Based on solid theoretical foundations and empirical research, it clarifies the elements involved in the formation and evaluation of sustainability strategies in firms, helping managers to prioritize eco-investments and transform them into sources of competitive advantage and new market spaces.

The Remote Control Approach - How to Apply Scaffolds to Existing Collaborative Learning Environments
In this paper we present an architecture for the integration of tutoring and process scaffolds into existing collaborative applications. The architecture allows to combine existing research results concerning collaborative processes and their formalization, and existing and tested collaborative learning environments. The architecture allows to control the learning environments either by a human or a pedagogic agent. Both types of tutors are using the same set of primitives - either via an intuit
Cognitive tools for discovery learning
Cognitive tools, defined here as instruments that support or perform cognitive processes for learners in order to support learning, can bridge the difference between open learning environments, like discovery learning environments and traditional supportive instructional environments. This article discusses a definition of the concept of cognitive tool and its use in learning. Two examples of cognitive tools for discovery environments are presented, and it is made clear how these tools can serve
An Experimental Study on Peer Selection in a P2P Network over PlanetLab
Peer selection is an important aspect in many P2P applications requiring efficient assignment and execution of jobs to peer nodes and search and file transfer, among others. Due to increasing interest of using P2P systems for distributed computing, peer selection is taking relevance and several models have been proposed in the P2P literature. Yet, there are very few experimental studies for peer selection in P2P networks deployed in real large scale networks. In this work we present an experimen
Verbal Coaching During a Real-time Task
TRANSoM is a collaborative effort among university and industry researchers aimed at producing an intelligent tutoring system for training pilots of remotely operated vehicles (ROVs). ROVs are unmanned, tethered, underwater vehicles used in a range of applications such as inspection, search and salvage, and mine countermeasures. Pilots have to learn to maneuver the ROV, keeping track of its tether and its surroundings, using little more than a video camera and sonar. To minimize workload while a
ZAPs: Using interactive programs for learning psychology
ZAPs are short, self-contained computer programs that encourage students to experience psychological phenomena in a vivid, self-explanatory way, and that are meant to evoke enthousiasm about psychological topics. ZAPs were designed according to principles that originate from experiential and discovery learning theories. The interactive approach that is offered invites students to engage in subject matter through exploration, experience, and discovery of psychology. In an empirical study the effe

Case Study of Virtual Organization Learning and Knowledge Testing Environments
The proposed web-based knowledge assessment is based on flexible educational model and allows to implement adaptive control of learning process as well as to implement knowledge testing environment according to the requirements of student's knowledge level, their personal abilities and his subject learning history. The learner knowledge model can be constructed as a sub graph of the global knowledge domain graph. The paper presents the architecture of student self-evaluation and on-line assessm
Computer-Supported Scripting of Interaction in Collaborative Learning Environments: Framework on mul
Collaboration scripts aim to facilitate effective interaction patterns for collaborative learning that do not occur spontaneously. So far, diverse non-generic scripts have been conceptualized and investigated in CSCL environments. The specification of collaboration scripts aims to provide a common terminolgy for describing scripts and to abstract the core design principles of scripts to better understand effects and mechanisms of collaboration scripts and to apply and re-apply collaboration scri
Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will
An Introduction to the Simple Role of Numbers in Social Science Research
Social science is facing increasing demands for research involving 'quantitative' approaches. Among these are the need, expressed by policy-makers, for practical evidence about what works, and the demand, exemplified by the new ESRC guidelines for research training, that all researchers learn something about techniques of analysis involving numbers. At the same time, however, traditional 'quantitative' approaches are facing a major upheaval caused by growing criticism of null hypothesis signific
A National Study of Chronic Disease Prevalence and Access to Care in Uninsured U.S. Adults
Background: No recent national studies have assessed chronic illness prevalence or access to care among persons without insurance in the United States. Objective: To compare reports of chronic conditions and access to care among U.S. adults, by self-reported insurance status. Design: Population-based survey. Setting: National Health and Nutritional Examination Survey (1999–2004). Participants: 12 486 patients age 18 to 64 years. Measurements: Estimates of national rates of cardiovascular d
This lesson builds upon the previous two (Newton's Second Law and the First Law of Thermodynamics) by explaining that conservation of energy is not perfectly observed, in that energy is lost as it is transferred from kinetic to potential, and vice-versa.

Phase Relations in Reservoir engineering
In this course you will learn about phase relations as applied to oil and/or gas reservoir processes, enhanced oil recovery, gas pipeline transportation, natural gas processing and liquefaction, and other problems in petroleum production. The primary objective of the course is to apply the thermodynamics of phase equilibrium to the framework for phase behavior modeling of petroleum fluids. The focus of the course will be on equilibrium thermodynamics and its relevance to phase behavior predictio
Every month we will give you a math/statistics brain teaser that lets you test your knowledge with a fun problem.Many of the ideas in these Teasers come from thoughts formed by some of the great mathematical/statistical geniuses in history.
