Environmental consciousness has become critical in the design and operation of globally integrated supply chain networks. This research examines the carbon footprint across supply chains and thus contributes to the knowledge and practice of green supply chain management. The analytical model uses the long-range Lagrangian and the Eulerian transport methods. Analytical and finite difference methods are used to approximate the three-dimensional infinite footprint model. A simplified numerical example validates and illustrates the proposed approach. The results show that carbon emissions across stages in a supply chain can constitute a significant threat that warrants careful attention in the design phase of supply chains. © 2010 Elsevier B.V.All rights reserved.

Due to the proliferation and abundance of information on the web, ranking algorithms play an important role in web search. Currently, there are some ranking algorithms based on content and connectivity such as BM25 and PageRank. Unfortunately, these algorithms have low precision and are not always satisfying for users. In this paper, we propose an adaptive method, called A3CRank, based on the content, connectivity, and click-through data triple. Our method tries to aggregate ranking algorithms such as BM25, PageRank, and TF-IDF. We have used reinforcement learning to incorporate user behavior and find a measure of user satisfaction for each ranking algorithm. Furthermore, OWA, an aggregation operator is used for merging the results of the various ranking algorithms. A3CRank adapts itself with user needs and makes use of user clicks to aggregate the results of ranking algorithms. A3CRank is designed to overcome some of the shortcomings of existing ranking algorithms by combining them together and producing an overall better ranking criterion. Experimental results indicate that A3CRank outperforms other combinational ranking algorithms such as Ranking SVM in terms of P@n and NDCG metrics. We have used 130 queries on University of California at Berkeley's web to train and evaluate our method. © 2009 Elsevier Ltd. All rights reserved.

Based on a sample of 1,684 manufacturing companies from the Taiwanese Technological Innovation Survey for the period from 2004-2006, the paper examines the relationship between different types of domestic and foreign based collaborative partners and different levels of product innovation radicalness. A complex network of relationships emerges where the level of innovation radicalness is associated with the type and geographic location of partners. A firm that aims to develop radical innovations should consider collaborating with domestic universities and competitors but also with customers in foreign countries. © 2015 IEEE.

As large-scale sensor networks become more feasible, properties such as stateless nature and low maintenance overhead make position-based routing increasingly more attractive. Motivated by the fact that sensor networks would probably be deployed in a three-dimensional space, we present a novel 3D geographical routing (3DGR) algorithm that makes use of the position information to route packets from sources to destinations with high path quality and reliability. The locality and high scalability of this algorithm make it suitable for wireless sensor networks. It provides high adaptability to changes in topology and recovery of link failures which increases its reliability. We also incorporate battery-aware energy efficient schemes to increase the overall lifetime of the network. To reduce latency, a method of keeping a small record of recent paths is used. We also show that location errors will still result in good performance of our algorithm while the same assumptions might yield bad performance or even complete failures in other popular geographical routing algorithms. We evaluate the 3DGR protocol using simulation. Compared to other geographic routing algorithms, we find that 3DGR exhibits noticeably longer network lifetime, smaller path stretch, smaller end-to-end delay, and better packet delivery ratio.

Integrating social presence theory and social identity theory, this study brings system design and social influence aspects together to explain their joint effects on knowledge contribution in virtual communities (VCs). Different from most prior information systems (IS) research that adopts a uni-dimensional approach and restricts social presence to be the subjective nature of media, we developed and empirically tested a model explaining the effects of multi-dimensional social presence on social identification processes and knowledge contribution. An online survey was conducted with four different VCs of interest. The results showed the difference in relative contribution of social presence dimensions on social identity as well as knowledge contribution. Both practical and theoretical implications are discussed. © 2010 Taylor & Francis.

This study was driven by three underlying motivations. One of them is the gap between high penetration rate of mobile phone and relatively low adoption rate of m-commerce. The second is to reconcile the inconsistent findings in prior IT adoption research regarding the consistency of the relationship between attitude and intention. Finally, we hope to provide the theoretical underpinning for various interventions to promote m-commerce adoption. In this study, we extended the theory of planned behavior (TPB) by integrating confidence as a moderator for the relationship between attitude and intention. Furthermore, trial, communication and observation are identified as the sources for confidence with m-commerce and their effects are mediated through exposure. The research model was empirically tested and supported. Both theoretical and practical implications are discussed.

Common transverse reinforcement of reinforced concrete members with circular cross-section consists of round ties or spirals. Its purpose in members that are not subjected to significant shear loading is to provide proper confinement for concrete, and eliminate buckling of the longitudinal reinforcement bars. If spirals are to be used as both shear enabler and confiner for reinforced concrete beams then, under combined action of moment and shear, spirals will be required to provide or contribute to proper shear resistance. Hence, a proper assessment for spiral shear contribution is required. The validity of concepts which underline current methods for shear design used in design codes will be investigated in this paper, especially for beams with the shear configuration, which violates basic code rules on forming a truss. A simplified sectional model based on sectional crack analysis and a corresponding approach in assessing the shear contribution of spiral shear reinforcement are presented. A method for evaluating the shear capacity of beams with spirals has also been proposed.

The advances in computer science and structural designs are deeply intertwined. Rising energy costs and a growing green movement are driving the adoption of Wireless Sensor Networks (WSN) for building automation. While previous WSN products have been applied in a variety of smart applications including supply chains and industrial applications, a cross industry effort between civil engineers and network engineers is underway to unify sensor networks with construction management that will simplify development, attract new entrants, and encourage innovation. With the prospect of installing sensors almost anywhere, buildings can optimize their energy consumption, improve safety and security, and reduce operating expenses. We model a sensor node as a replacement of a solar panel. A significant efficiency increase of solar energy gains can only be obtained by optimal exposure of the panels to sunlight. In this paper, we propose a system that controls the movement of rotating buildings in order to optimize the energy gained by the use of solar panels installed both on the building rooftop horizontally and on the sides of the building vertically. © 2013 IEEE.

One of the key objectives of knowledge management is to transfer knowledge quickly and efficiently from experts to novices, who are different in terms of the structural properties of domain knowledge or knowledge structure. This study applies experts' semantic networks to hypertext navigation design and examines the potential of the resulting design, i.e., semantic hypertext, in facilitating knowledge structure acquisition and problem solving. Moreover, we argue that the level of sophistication of the knowledge structure acquired by learners is an important mediator influencing the learning outcomes (in this case, problem solving). The research model was empirically tested with a situated experiment involving 80 business professionals. The results of the empirical study provided strong support for the effectiveness of semantic hypertext in transferring knowledge structure and reported a significant full mediating effect of knowledge structure sophistication. Both theoretical and practical implications of this research are discussed. © 2010 ASIS&T.

Various and independent studies are showing that an exponential increase of chronic diseases (CDs) is exhausting governmental and private healthcare systems to an extent that some countries allocate half of their budget to healthcare systems. To benefit from the IT development, e-health monitoring and prevention approaches revealed to be among top promising solutions. In fact, well-implemented monitoring and prevention schemes have reported a decent reduction of CDs risk and have narrowed their effects, on both patients' health conditions and on government budget spent on healthcare. In this paper, we propose a framework to collect patients' data in real time, perform appropriate nonintrusive monitoring, and propose medical and/or life style engagements, whenever needed and appropriate. The framework, which relies on service-oriented architecture (SOA) and the Cloud, allows a seamless integration of different technologies, applications, and services. It also integrates mobile technologies to smoothly collect and communicate vital data from a patient's wearable biosensors while considering the mobile devices' limited capabilities and power drainage in addition to intermittent network disconnections. Then, data are stored in the Cloud and made available via SOA to allow easy access by physicians, paramedics, or any other authorized entity. A case study has been developed to evaluate the usability of the framework, and the preliminary results that have been analyzed are showing very promising results. © 2013 IEEE.
