Co-creating the cities of the future

In recent years, the evolution of urban environments, jointly with the progress of the Information and Communication sector, have enabled the rapid adoption of new solutions that contribute to the growth in popularity of Smart Cities. Currently, the majority of the world population lives in cities encouraging different stakeholders within these innovative ecosystems to seek new solutions guaranteeing the sustainability and efficiency of such complex environments. In this work, it is discussed how the experimentation with IoT technologies and other data sources form the cities can be utilized to co-create in the OrganiCity project, where key actors like citizens, researchers and other stakeholders shape smart city services and applications in a collaborative fashion. Furthermore, a novel architecture is proposed that enables this organic growth of the future cities, facilitating the experimentation that tailors the adoption of new technologies and services for a better quality of life, as well as agile and dynamic mechanisms for managing cities. In this work, the different components and enablers of the OrganiCity platform are presented and discussed in detail and include, among others, a portal to manage the experiment life cycle, an Urban Data Observatory to explore data assets, and an annotations component to indicate quality of data, with a particular focus on the city-scale opportunistic data collection service operating as an alternative to traditional communications.This work has been partially funded by the research project OrganiCity, under the grant agreement No. 645198 of the European Union’s Horizon 2020 research and innovation program

A framework to provide charging for third party composite services

Includes synopsis.Includes bibliographical references (leaves 81-87).Over the past few years the trend in the telecommunications industry has been geared towards offering new and innovative services to end users. A decade ago network operators were content with offering simple services such as voice and text messaging. However, they began to notice that these services were generating lower revenues even while the number of subscribers increased. This was a direct result of the market saturation and network operators were forced to rapidly deploy services with minimum capital investment and while maximising revenue from service usage by end users. Network operators can achieve this by exposing the network to external content and service providers. They would create interfaces that would allow these 3rd party service and content providers to offer their applications and services to users. Composing and bundling of these services will essentially create new services for the user and achieve rapid deployment of enhanced services. The concept of offering a wide range of services that are coordinated in such a way that they deliver a unique experience has sparked interest and numerous research on Service Delivery Platforms (SDP). SDP‟s will enable network operators to be able to develop and offer a wide-variety service set. Given this interest on SDP standardisation bodies such as International Telecommunications Union – Telecommunications (ITU-T), Telecoms and Internet converged Servicers and Protocols for Advanced Networks) (TISPAN), 3rd Generations Partnership Project (3GPP) and Open Mobile Alliance (OMA) are leading efforts into standardising functions and protocols to enhance service delivery by network operators. Obtaining revenue from these services requires effective accounting of service usage and requires mechanisms for billing and charging of these services. The IP Multimedia subsystem(IMS) is a Next Generation Network (NGN) architecture that provides a platform for which multimedia services can be developed and deployed by network operators. The IMS provides network operators, both fixed or mobile, with a control layer that allows them to offer services that will enable them to remain key role players within the industry. Achieving this in an environment where the network operator interacts directly with the 3rd party service providers may become complicated

Awareness and usage of electronic library resources in open distance learning by third-year students in the School of Arts at the University of South Africa

During the 21st century, electronic resources have become an important component in every sector of society and the academic sector is no exception. Academic libraries worldwide have adopted the technologies involved in electronic resources, with some replacing their traditional collections with e-resources, which are more accessible by users. This study was conducted at the University of South Africa (Unisa) and was aimed at investigating the levels of awareness and usage of e-resources by third-year students in the School of Arts. The study used the descriptive survey study design, which is quantitative in approach. The target population comprised of 5 377 third-year students enrolled in the seven departments in the School of Arts and a proportional sample of 360 students was drawn from the population by using stratified random sampling. Library staff was also included in the study, in order to determine students’ usage patterns of e-resources and to establish initiatives available at the Unisa Library to increase awareness and use of e-resources. Online questionnaires distributed via Survey Monkey were used as the data collection instrument. The study established that the Unisa Library subscribes to a wide range of e-resources and has a number of initiatives in place to encourage the awareness and usage of these resources. However, 50, 3% of the student respondents were unaware of the availability of Unisa e-resources. The study also established that the majority of students use e-resources for study and research and that, although they have basic information and communication technologies (ICTs) skills, the majority of students lack advanced information search and retrieval skills, which are required to utilise e-resources properly. The four main barriers that prevent students from accessing and using e-resources were the cost of access to the internet, unavailability of relevant literature for studies, lack of time to do online searches and preference for information freely available on the internet. To encourage increased awareness and use of e-resources, the study recommend the development of an e-resources marketing strategy, the introduction of an information literacy module for all first-year students, the provision of infrastructure and technologies for access, development of specialised library assistance services, balancing of the electronic library collections across different subjects, tutors including more e-resources references in study guides and tutorial letters and hiring of more library staff. The study concludes that the Unisa Library has a wide variety of electronic library resources and services needed in academic institutions, but awareness and usage of the resources is quite low, due to several factors highlighted in the study. Therefore, the Library should step forward and ensure that the resources are fully utilised by following the recommendations suggested in the study.Information ScienceM. Inf
