Characterizing the cultural ecosystem services of coastal sand dunes

Coastal sand dunes provide an array of important benefits that are supported by coastal geomorphic processes and location-specific ecosystems, including direct and indirect economic benefits to humans. Coastal sand dune ecosystems are ecologically important, but their specific values and uses are little studied, poorly understood, and underappreciated. Michigan, USA, is home to the largest land area of freshwater coastal sand dunes in the world. This study used an online survey that allowed participants to record the types of activities in which they engaged during visits and respond to questions about the importance of the cultural ecosystem services of coastal sand dunes. The survey captured the responses of 3610 individuals, a majority of whom rated scenic beauty, protection for future generations, protection of a unique ecosystem, and outdoor recreation as extremely important or very important. The survey results provide some preliminary insights into the role of cultural ecosystem services of coastal sand dunes in providing and sustaining benefits for humans and how these benefits and values are perceived by the public. These insights have important implications for policy makers responsible for coastal zone management in the Great Lakes region and in other areas characterized by coastal sand dunes ecosystems.     

Interval type 2-based hybrid fuzzy evaluation of financial services in E7 economies with DEMATEL-ANP and MOORA methods

The financial services are key instrument for the right evolution of economy, mainly in the emerging countries. Therefore, the evaluation of the financial services is crucial for the economic development of such a type of countries. Different methods have been applied to accomplish this service evaluation, but its complexity greatly involves uncertain information. Therefore, this paper aims at considering in a more comprehensive way the managing of such uncertainty by the use of interval type-2 fuzzy sets. Hence, it will be proposed a novel evaluation methodology based on a hybrid multi-criteria decision method integrating DEMATEL-ANP (DANP) and MOORA able to deal with interval type-2 fuzzy sets. For the robustness check, the TOPSIS and VIKOR based on interval type-2 fuzzy sets are compared with the MOORA method and the sensitivity analysis is also applied to analyze the consistency of decision makers’ priorities. This novel hybrid methodology will be used to evaluate the financial service performance in the emerging seven (E7) economies to conclude what kind of strategic actions should be taken by governments to improve their financial systems as well as to identify a ranking regarding the financial service quality of the E7 economies.

Understanding the trust of software‐intensive distributed systems

An early understanding of the trust concerns while composing a distributed system from independently developed software services saves time and effort. It also allows the developer of such distributed systems to reason about the trust‐related properties of these systems. Although there are prevalent approaches for evaluating the trust of such systems, it is not clear which approach, if any, is the most comprehensive and best suited for a given situation. Moreover, there is no agreement about a unified approach, for quantifying trust, which can be applied to the entire software life‐cycle of distributed systems. This article, first, motivates the need for such a quantification of trust via a case study from the domain of indoor tracking. It then provides a comprehensive survey of current approaches that define trust, in general domains, and then focuses on the relevant approaches from the domain of software‐oriented distributed systems. These prevalent efforts are categorized into groups using existing clustering tools and then are further analyzed for their comprehensiveness. The analysis depicts: (1) many trust‐related efforts and associated models have their own constrained views of trust; (2) different trust models focus on different aspects of trust and life‐cycle details; and (3) it is difficult to interoperate across different trust models. Hence, the paper identifies a set of principles that can assist in quantifying and evaluating the trust throughout the software life‐cycle of distributed systems. These principles, then, are applied to the aforementioned case study to provide an outline of how trustworthy distributed systems can be composed from independent software services.

A cost‐efficient resource provisioning algorithm for DHT‐based cloud storage systems

Personal cloud storage provides users with convenient data access services. Service providers build distributed storage systems by utilizing cloud resources with distributed hash table (DHT), so as to enhance system scalability. Efficient resource provisioning could not only guarantee service performance, but help providers to save cost. However, the interactions among servers in a DHT‐based cloud storage system depend on the routing process, which makes its execution logic more complicated than traditional multi‐tier applications. In addition, production data centers often comprise heterogeneous machines with different capacities. Few studies have fully considered the heterogeneity of cloud resources, which brings new challenges to resource provisioning. To address these challenges, this paper presents a novel resource provisioning model for service providers. The model utilizes queuing network for analysis of both service performance and cost estimation. Then, the problem is defined as a cost optimization with performance constraints. We propose a cost‐efficient algorithm to decompose the original problem into a sub‐optimization one. Furthermore, we implement a prototype system on top of an infrastructure platform built with OpenStack. It has been deployed in our campus network. Based on real‐world traces collected from our system and Dropbox, we validate the efficiency of our proposed algorithms by extensive experiments. Copyright © 2016 John Wiley & Sons, Ltd.     

Net-positive building carbon sequestration

A greater appreciation of architecture as a means to drive social, economic and environmental sustainability is emerging around the world. Practices are beginning to adopt closed-loop and cradle-to-cradle strategies, and some are even aiming toward net-positive design. However, life cycle assessment (LCA) tools do not measure ‘beyond zero’. The question of how net-positive carbon sequestration (i.e. impacts beyond net-zero) can be assessed within LCA is explored through a proposed carbon amortization performance (CAP) method. CAP overlays energy-related carbon and biomass sequestration over the building life cycle. CO₂ equivalence (CO₂e) is used to combine both positive and negative impacts from different sources. Net-positive contributions are defined as those exceeding ‘zero operational carbon’ – after the embodied carbon is paid back during the life cycle. The CAP method was tested on a building design with the technical support of multidisciplinary experts. The results indicate that a building can sequester more carbon over its life cycle than it emits by using on-site current renewable energy technology and extensive building-integrated vegetation. Buildings designed on net-positive development principles can potentially reverse their carbon impact and begin to regenerate their regions, while providing multiple eco-services.
