Growing social concerns over the environmental externalities associated with business activities are pushing firms to identify activities that create economic value with less environmental impact and to become more eco-efficient. Over the past two decades, researchers have increasingly used frontier efficiency models to evaluate productive efficiency in the presence of undesirable outputs, such...

Land use/land cover change has been attracting increasing attention in the field of global environmental change research because of its role in the social and ecological environment. To explore the ecological risk characteristics of land use change in the Poyang Lake Eco-economic Zone of China, an eco-risk index was established in this study by the combination of a landscape disturbance index w...

The present study focused on the synthesis of silver nanoparticles using the aqueous extract of Ulva flexousa (green seaweed). Ten ml of the aqueous extract of alga was mixed with 90 ml of 1mM aqueous AgNO3 solution for reducing of Ag+ ions. The synthesized silver nanoparticles were characterized by UV-Vis spectra, XRD (X-ray diffraction), TEM (Transmission electron microscopy) and FT-IR (Fouri...

We present a general step-by-step extending approach to parallel execution of enumeration of combinatorial objects (ECO).Themethodology extends a famous enumeration algorithm,OrderlyGeneration, which allows concurrently generating all objects of size n + 1 from all objects of size n. To the best of our knowledge, this is the first time there is an attempt to plug parallel computing into Orderly...

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

Stream networks are branched structures wherein water and energy move between land and atmosphere, modulated by evapotranspiration and its interaction with the gravitational dissipation of potential energy as runoff. These actions vary among climates characterized by Budyko theory, yet have not been integrated with Horton scaling, the ubiquitous pattern of eco-hydrological variation among Strah...

Eco-labels emphasize information disclosure as a tool to induce environmentally friendly behaviors by both firms and consumers. The goal of eco-labels is to reduce information asymmetry between producers and consumers over the environmental attributes of a product or service. However, by focusing on this information asymmetry, rather than on how the label meets consumer needs, eco-labels may se...

Eco-efficiency, being a matter of concern all over the world, is gaining increasing attention in the fields of economic and environment. This paper just investigates the relationship between economic development and environmental sustainability in Chinese provinces focused on the eco-efficiency calculation. In this paper, by the index of eco-efficiency into economic effect (er) and environment ...
