In the recent past Environmental Education (EE) has been introduced as one of the core course in the curriculum of higher education in India. The objective was to make every student aware of the biodiversity and infuse a pro-environmental attitude in them. The efforts to achieve this objective through traditional methods of classroom teaching, predefined syllabus and textbooks has not produced ...

An important challenge for service-based systems is to be able to select services based on feedback from service consumers and, therefore, to be able to distinguish between good and bad services. However, ratings are normally provided to a service as a whole, without taking into consideration that services are normally formed by a composition of other services. In this paper we propose an appro...

Does the type of post-auction feedback affect bidding behavior in the first price auction? Filiz-Ozbay and Ozbay (2007) find that such manipulation can increase bids in a one-shot auction. They explain their finding by anticipated regret combined with the assumption that feedback directly affects salience of regret relative to material payoff. We revisit this important market design issue using...

A small delay in the feedback loop of a singularly perturbed system may destabilize it; however, without the delay, it is stable for all small enough values of a singular perturbation parameter . Su3cient and necessary conditions for preserving stability, for all small enough values of delay and , are obtained in two cases: in the case of delay proportional to and in the case of independent del...

For discrete-time semi-linear systems satisfying an accessibility condition asymptotic null controllability is equivalent to exponential feedback sta-bilizability using a piecewise constant feedback. A constructive procedure that yields such a feedback is presented.

A theoretical framework to consensus building within a networked social group is put forward. This article investigates a trust based estimation and aggregation methods as part of a visual consensus model for multiple criteria group decision making with incomplete linguistic information. A novel trust propagation method is proposed to derive trust relationship from an incomplete connected trust...

there is no doubt that augmented feedback has an important role in improvinglearning. however, it is the content of the feedback which is challenging. the aimof the present study was to examine the effect of feedback on successful versusunsuccessful trials on simple and complex tracking tasks. for this purpose, 48undergraduate right-handed male and female students of hakim sabzevari teachertrai...

Many natural, complex systems are remarkably stable thanks to an absence of feedback acting on their elements. When described as networks these exhibit few or no cycles, and associated matrices have small leading eigenvalues. It has been suggested that this architecture can confer advantages to the system as a whole, such as "qualitative stability," but this observation does not in itself expla...

In this paper, we present our work in progress towards employing complex user feedback and its context in recommender systems. Our work is generally focused on small or medium-sized e-commerce portals. Due to the nature of such enterprises, explicit feedback is unavailable, but implicit feedback can be collected in both large amount and rich variety. However, some perceived values of implicit f...

Internet auctions for consumers’ goods are an increasingly popular selling venue. We have observed that many sellers, instead of offering their entire inventory in a single auction, split it into sequential auctions of smaller lots, thereby reducing the negative market impact of larger lots. Information technology also makes it possible to collect and analyze detailed bid data from online aucti...
