Using Open Stack for an Open Cloud Exchange(OCX)
We are developing a new public cloud, the Massachusetts Open Cloud (MOC) based on the model of an Open Cloud eXchange (OCX). We discuss in this paper the vision of an OCX and how we intend to realize it using the OpenStack open-source cloud platform in the MOC. A limited form of an OCX can be achieved today by layering new services on top
of OpenStack. We have performed an analysis of OpenStack to determine the changes needed in order to fully realize the OCX model. We describe these proposed changes, which although
significant and requiring broad community involvement will provide functionality of value to both existing single-provider clouds as well as future multi-provider ones

Canadian national sport organisations’ use of the web for relationship marketing in promoting sport participation
Sport participation development requires a systematic process which involves knowledge creation, dissemination and interactions between National Sport Organisations, participants, clubs and associations as well as other agencies. Using a relationship marketing approach (Grönroos, 1997, Gummesson, 2002, Olkkonen, 1999), this paper addressed the question ‘How do Canadian NSOs use the Web, in terms of functionality and services offered, to create and maintain relationships with sport participants and their sport delivery partners?’ Ten Canadian NSOs’ websites were examined: functionality was analysed using Burgess and Cooper’s (2000) eMICA model, while NSOs’ utilisation of the Internet to establish and maintain relationships with sport participants was analysed using Wang, Head and Archer’s (2000) relationship-building process model for the Web. It was found that Canadian NSOs were receptive to the use of the Web, but their information-gathering and dissemination activities, which make-up the relationship-building process, appear sparse, and in some cases are lagging behind the voluntary sector in the country
Organic Exporter Guide
This guide was developed for the programme 'Export Promotion of Organic Products from Africa' (EPOPA), implemented by Agro Eco and Grolink. The focus of this guide is on export marketing of organic agricultural products. Finished consumer products and other concepts of certification such as Fair Trade and EurepGAP are briefly discussed as well. The guide is written for African exporters starting with organic exports. It may also be useful for business supporters involved in export marketing
Lightweight Security for Network Coding
Under the emerging network coding paradigm, intermediate nodes in the network
are allowed not only to store and forward packets but also to process and mix
different data flows. We propose a low-complexity cryptographic scheme that
exploits the inherent security provided by random linear network coding and
offers the advantage of reduced overhead in comparison to traditional
end-to-end encryption of the entire data. Confidentiality is achieved by
protecting (or "locking") the source coefficients required to decode the
encoded data, without preventing intermediate nodes from running their standard
network coding operations. Our scheme can be easily combined with existing
techniques that counter active attacks.Comment: Proc. of the IEEE International Conference on Communications (ICC

Solutions for Impact Investors: From Strategy to Implementation
In writing this monograph, our main goal is to provide impact investors with tools to tighten the link between their investment decisions and impact creation. Our intent is threefold: to attract more capital to impact investing; to assist impact investors as they move from organizational change to executing and refining their impact investment decision-making process; and to narrow the gap within foundations between program professionals and investment professionals thereby contributing to a mutual understanding and implementation of a portfolio approach to impact investing.Additionally, we intend to help break down the barriers making it difficult to identify opportunities in impact investing. To this end, we provide examples throughout the monograph and at www.rockpa.org/impactinvesting of impact investment opportunities in most major asset classes.While we understand the important role that impact investors can play in providing financial capital, we also want to acknowledge the wide range of non-financial resources needed to address the world's problems. Our intent with this monograph is not to provide a comprehensive list of investments across asset classes nor any type of investment advice with regard to the selected profiles. We strongly encourage the reader to conduct their own assessment and evaluation for risk and suitability before considering any investment
InterCloud: Utility-Oriented Federation of Cloud Computing Environments for Scaling of Application Services
Cloud computing providers have setup several data centers at different
geographical locations over the Internet in order to optimally serve needs of
their customers around the world. However, existing systems do not support
mechanisms and policies for dynamically coordinating load distribution among
different Cloud-based data centers in order to determine optimal location for
hosting application services to achieve reasonable QoS levels. Further, the
Cloud computing providers are unable to predict geographic distribution of
users consuming their services, hence the load coordination must happen
automatically, and distribution of services must change in response to changes
in the load. To counter this problem, we advocate creation of federated Cloud
computing environment (InterCloud) that facilitates just-in-time,
opportunistic, and scalable provisioning of application services, consistently
achieving QoS targets under variable workload, resource and network conditions.
The overall goal is to create a computing environment that supports dynamic
expansion or contraction of capabilities (VMs, services, storage, and database)
for handling sudden variations in service demands.
This paper presents vision, challenges, and architectural elements of
InterCloud for utility-oriented federation of Cloud computing environments. The
proposed InterCloud environment supports scaling of applications across
multiple vendor clouds. We have validated our approach by conducting a set of
rigorous performance evaluation study using the CloudSim toolkit. The results
demonstrate that federated Cloud computing model has immense potential as it
offers significant performance gains as regards to response time and cost
saving under dynamic workload scenarios.Comment: 20 pages, 4 figures, 3 tables, conference pape
An Ethical Basis for Relationship Marketing: A Virtue Ethics Perspective
Purpose – The purpose of this paper is to provide an ethical foundation for relationship marketing using a virtue ethics approach.
Design/methodology/approach – The approach is a conceptual one providing a background on relationship marketing from both American and European perspectives. Earlier studies published in EJM on relationship marketing are featured in a table.
Findings – The proposed ethical relationship marketing approach has three stages (establishing, sustaining and reinforcing) that are paired with specific virtues (trust, commitment and diligence). These and other facilitating virtues are shown in a figure.
Research limitations/implications – The model and its components have yet to be tested empirically. Some strategies for undertaking such research are discussed.
Practical implications – Several European and American companies that currently practice ethical relationship marketing are discussed.
Originality/value – Although relationship marketing has been studied for a number of years by many scholars, the ethical basis of it has not been thoroughly examined in any previous work
