To reduce energy consumption in buildings, researchers have in the recent decade explored the potential of changing occupants’ energy consumption behaviors using eco-feedback technologies. Energy consumption behavior is a type of consumer behavior, which has been proven cultural-specific in prior research. This paper aims to examine the impact of cultural differences on the effectiveness of eco...
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...
Context. Living conditions for elderly people, including household services and healthcare provision in the home, have become a hot topic worldwide with the aging of the population and the rising societal costs for healthcare. The rapid increase of elderly populations putting a heavy strain on social welfare, healthcare providers, hospitals, nursing homes and service homes for elderly as well a...
Eco-efficiency is concerned with the efficient and sustainable use of resources in farm production and land management. It can be increased either by altering the management of individual crop and livestock enterprises or by altering the land-use system. This paper concentrates on the effects of crop sequence and rotation on soil fertility and nutrient use efficiency. The potential importance o...
The present study, for the first time, presents a feasible protocol for the preparation of β-cyclodextrin/ imidazolium based dicationic ionic liquid, [βCD/Im](OTs)2, and its application as an efficient and eco-friendly microvessel and host ionic liquid system for the regioselective ring opening of the epoxides in water. No evidence for the formation of diol by-products or side reacti...

Transferring product environmental information to consumer to promote eco-product in the market and to promote sustainable consumption is considered as an important challenge especially according to the Integrated Product Policy (IPP) and the eco-design directive for Energy Using Products (EUP). In this paper the three core areas of consumer analysis on eco-products are identified. In order to ...
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 ...
BACKGROUND The non-invasive assessment of airway inflammation is potentially advantageous in asthma management. Exhaled carbon monoxide (eCO) measurement is cheap and has been proposed to reflect airway inflammation and oxidative stress but current data are conflicting. The purpose of this meta-analysis is to determine whether eCO is elevated in asthmatics, is regulated by steroid treatment and...
Event-based communication is useful in many application domains, ranging from small, centralised applications to large, distributed systems. Many different event models have been developed to address the requirements of different application domains. One such model is the ECO model which was designed to support distributed virtual world applications. Like many other event models, ECO has event ...
