What Next? The Quest to Protect Journalists and Human Rights Defenders in a Digital World
Around the world, governments and non-state actors are using sophisticated techniques to monitor, threaten, and harass human rights defenders (HRDs) and journalists. The growing use of digital technology has empowered activists to rally citizens around common causes and hold governments accountable, but it has also opened new doors for surveillance and harassment of activists and citizens' activities online. On November 14 -- 15, 2013, Freedom House, funded by the United States Agency for International Development (USAID), held a global conference in Mexico City entitled "What Next? The Quest to Protect Journalists and Human Rights Defenders in a Digital World," which brought together over 60 policymakers, donors, and activists to explore the full range of emerging threats and best strategies to overcome them; take an honest look at what is and is not working; and chart a path forward for more proactive and realistic solutions to build the resilience, sustainability, and relevance of HRDs and their movements. The conference sought to answer "what's next?" by identifying opportunities that can be exploited to build up frontline defenders and their ability to uphold human rights principles fearlessly and strategically at home and abroad
On the Deployment of Healthcare Applications over Fog Computing Infrastructure
Fog computing is considered as the most promising enhancement of the traditional cloud computing paradigm in order to handle potential issues introduced by the emerging Interned of Things (IoT) framework at the network edge. The heterogeneous nature, the extensive distribution and the hefty number of deployed IoT nodes will disrupt existing functional models, creating confusion. However, IoT will facilitate the rise of new applications, with automated healthcare monitoring platforms being amongst them. This paper presents the pillars of design for such applications, along with the evaluation of a working prototype that collects ECG traces from a tailor-made device and utilizes the patient's smartphone as a Fog gateway for securely sharing them to other authorized entities. This prototype will allow patients to share information to their physicians, monitor their health status independently and notify the authorities rapidly in emergency situations. Historical data will also be available for further analysis, towards identifying patterns that may improve medical diagnoses in the foreseeable future

Secure communication using dynamic VPN provisioning in an Inter-Cloud environment
Most of the current cloud computing platforms offer Infrastructure as a Service (IaaS) model, which aims to provision basic virtualised computing resources as on-demand and dynamic services. Nevertheless, a single cloud does not have limitless resources to offer to its users, hence the notion of an Inter-Cloud enviroment where a cloud can use the infrastructure resources of other clouds. However, there is no common framework in existence that allows the srevice owners to seamlessly provision even some basic services across multiple cloud service providers, albeit not due to any inherent incompatibility or proprietary nature of the foundation technologies on which these cloud platforms are built. In this paper we present a novel solution which aims to cover a gap in a subsection of this problem domain. Our solution offer a security architecture that enables service owners to provision a dynamic and service-oriented secure virtual private network on top of multiple cloud IaaS providers. It does this by leveraging the scalability, robustness and flexibility of peer- to-peer overlay techniques to eliminate the manual configuration, key management and peer churn problems encountered in setting up the secure communication channels dynamically, between different components of a typical service that is deployed on multiple clouds. We present the implementation details of our solution as well as experimental results carried out on two commercial clouds
Managing ubiquitous eco cities: the role of urban telecommunication infrastructure networks and convergence technologies
A successful urban management system for a Ubiquitous Eco City requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated, transparent and open decision making mechanism and necessary infrastructure and technologies. Rapidly developing information and telecommunication technologies and their platforms in the late 20th Century improves urban management and enhances the quality of life and place. Telecommunication technologies provide an important base for monitoring and managing activities over wired, wireless or fibre-optic networks. Particularly technology convergence creates new ways in which the information and telecommunication technologies are used. The 21st Century is an era where information has converged, in which people are able to access a variety of services, including internet and location based services, through multi-functional devices such as mobile phones and provides opportunities in the management of Ubiquitous Eco Cities. This paper discusses the recent developments in telecommunication networks and trends in convergence technologies and their implications on the management of Ubiquitous Eco Cities and how this technological shift is likely to be beneficial in improving the quality of life and place. The paper also introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for Ubiquitous Eco Cities

Dynamic virtual private network provisioning from multiple cloud infrastructure service providers
The Cloud infrastructure service providers currently provision basic virtualized computing resources as on demand and dynamic services but there is no common framework in existence that allows the seamless provisioning of even these basic services across multiple cloud service providers, although this is not due to any inherent incompatibility or proprietary nature of the foundation technologies on which these cloud platforms are built. We present a solution idea which aims to provide a dynamic and service oriented provisioning of secure virtual private networks on top of multiple cloud infrastructure service providers. This solution leverages the benefits of peer to peer overlay networks, i.e., the flexibility and scalability to handle the churn of nodes joining and leaving the VPNs and can adapt the topology of the VPN as per the requirements of the applications utilizing its intercloud secure communication framework
The Future of Disability in Alaska Summit & Follow-up Survey
The Future of Disability in Alaska Summit was held in Anchorage in the summer of 2013, May 9-10. The purpose was to gather perspectives from a diverse group of stakeholders to inform a vision of the future for people with disabilities in Alaska in five broad topical areas: 1) Housing Arrangements, 2) Advocacy, 3) Relationships, 4) Economic Wellbeing, and 5) Health. About 76 stakeholders participated in the summit including people with disabilities, family members, advocates, service providers, policymakers, and others. A follow-up online survey was conducted to gather information from a broader range of stakeholders and to get a sense of the highest priorities in each area. The purpose of the report and other products coming out of this effort is to inspire stakeholders to periodically reflect, individually and in groups, on how they are working toward the vision in a relevant area and taking action in the context of advocacy, policy/regulation, funding, and services/resources. The report states a vision for each of the five topical areas and includes many suggested strategies to accomplish it.Funded in part by Grant Number T7320663 from the Maternal and Child Health Bureau, Health Resources and Services Administration; and Grant Number 90DD0009-02-00 from the Administration on Intellectual and Developmental Disabilities, Administration for Community Living; both in the U.S. Department of Health and Human ServicesList of Tables / Executive Summary / Introduction / Method / Participants / Result
