Inappropriate land use has caused a series of environmental disasters such as floods and sand storms, and some of them involved unused land changes with highly localized distributions in arid and semi-arid regions with fragile ecosystems. As the third-rank category of first-level land use/cover in China, unused land (UL) is now playing an increasingly important role in protection of the natural...
OBJECTIVES Using the prediction of cancer outcome as a model, we have tested the hypothesis that through analysing routinely collected digital data contained in an electronic administrative record (EAR), using machine-learning techniques, we could enhance conventional methods in predicting clinical outcomes. SETTING A regional cancer centre in Australia. PARTICIPANTS Disease-specific data f...
OBJECTIVE In this 3 year randomized clinical trial the cost effectiveness of a 6 week educational/cognitive intervention (ECO) is compared with an educational discussion intervention (EDI) and a waiting list condition (WLC). METHODS A total of 131 patients with fibromyalgia were randomly allocated to the ECO, EDI, or WLC intervention. The ECO and EDI groups were followed for 12 months, wherea...
The content and calibration of the comprehensive generic 3D eutrophication model ECO for water and sediment quality is presented. Based on a computational grid for water and sediment, ECO is used as a tool for water quality management to simulate concentrations and mass fluxes of nutrients (N, P, Si), phytoplankton species, detrital organic matter, electron acceptors and related substances. ECO...
In this paper, we present an energy-aware informed prefetching technique called Eco-Storage that makes use of the application-disclosed access patterns to group the informed prefetching process in a hybrid storage system (e.g., hard disk drive and solid state disks). Since the SSDs are more energy efficient than HDDs, aggressive prefetching for the data in the HDD level enables it to have as mu...
Demographic population dynamics, gene flow, and local adaptation may influence each other and lead to coupling of ecological and evolutionary dynamics, especially in species inhabiting fragmented heterogeneous environments. Here, I review long-term research on eco-evolutionary spatial dynamics in the Glanville fritillary butterfly inhabiting a large network of approximately 4,000 meadows in Fin...
Traditional traffic control and transportation management systems mainly focus on the relief of congestions and the enhancement of traffic safety. It is proven however that, the transportation sector is one of the main sources with significant impacts on the environment, the entire climate, the public health, and the entire ecological system [1-4], which is also an increasing general public con...
This study examines whether shareholders are sensitive to corporations’environmental footprint. Specifically, we conduct an event study around the announcement of corporate news related to environment for all U.S. publicly-traded companies from 1980 to 2009. Consistent with the view that environmental corporate social responsibility (CSR) generates new and competitive resources for firms, we fi...
* Corresponding author: [email protected] Abstract The end-of-life (EOL) disassembly is an important process in the product retirement stage. In order to improve the ease of disassembly, it is essential to design a product which can be easily disassembled. In this paper, a novel concept of eco-architecture is introduced and a method for analyzing the eco-architecture of a product at the configura...
An antagonistic relationship is traditionally seen as existing between eco-education and technology, with conventional instructional approaches usually characterized by a commentator guiding students in field learning. Unfortunately, in this passive learning approach, the discovery of rich ecological resources in eco-environments to stimulate positive emotions and experiences is often condensed...
