We consider online resource allocation problems where given a set of requests our goal is to select a subset that maximizes a value minus cost type of objective function. Requests are presented online in random order, and each request possesses an adversarial value and an adversarial size. The online algorithm must make an irrevocable accept/reject decision as soon as it sees each request. The ...

The ubiquity of network-based information resources have given impetus for the development of intelligent software agents that will be able to (1) extract task-relevant information automatically or with little help from human users from various on-line information resources, (2) resolve the potential con icts among acquired knowledge from di erent information resources, and (3) more importantly...

Purpose Recent OECD (2010, 2011) reports argue that eco-innovation is the key to realising growth. The purpose of this paper is to analyse the drivers of eco-innovation and to compare the impact of eco-innovation and non-eco-innovation on firm performance. The paper provides insights into the role government regulation can play in directing and stimulating eco-innovation. Design/methodology/app...

Exhaled carbon monoxide (eCO) and fractional exhaled nitric oxide (FeNO) could reflect underlying inflammatory and oxidative stresses, which play important roles in pathogenetic pathways of metabolic syndrome (MetS). However, epidemiologic evidence was limited. We conducted a study in Wuhan-Zhuhai (WHZH) cohort of 3649 community participants to investigate the association between eCO, FeNO and ...

Previous studies discuss how regulatory, technological and market drivers increasingly challenge manufacturing industries to adopt eco-innovations. However, the understanding of the process by which eco-innovations are developed and commercialized as a result of these drivers is not yet well established, in particular because these drivers are perceived differently by the end-users and their su...
