Brinkel J. A user-centred evaluation of a mobile phone-based interactive voice response system to support infectious disease surveillance and access to healthcare for sick children in Ghana: users’ experiences, challenges and opportunities for large-scale application. Part of a concept and pilot study for mobile phone-based Electronic Health Information and Surveillance System (eHISS) for Africa. Bielefeld: Universität Bielefeld; 2020.Digital Health offers tremendous potential to change the face of health systems in all countries. Although the application of digital technologies in the health sector has become central to global health thinking, various implementation barriers still exist. One of the most significant is the process of user acceptance and adoption of new interventions, which still remains a neglected research area in sub-Saharan Africa. The synopsis is a synthesis of the findings of a three-year research study embedded within a larger research consortium that developed and piloted a mobile phone-based Electronic Health Information and Surveillance System for sub-Saharan Africa (eHISS) in Ghana. The system aimed to support sick children to assess the disease severity, to advice appropriate treatment and to collect data on the occurrence of symptom clusters. The thesis evaluated the usability and acceptance among users of the mobile health (mHealth) system (caregivers of children) by soliciting their views on their experiences while using the system. The doctoral thesis followed a human-centred design (HCD) circle and consisted of the following research activities; (i) the assessment of the state of research, (ii) the innovative field test of a prototype of the eHISS system and an assessment of users’ needs to drive the design, (iii) the evaluation of the clinical decision algorithm as backbone of the electronic system and (iv) the evaluation of experiences with the system after a six-month pilot phase of the system. A manuscript was developed from each research activity for publication, thus making a total of four papers that form the empirical basis of this thesis. Results showed that users are generally open to mHealth and interested in new technologies, and comprehensive knowledge on critical factors favouring and disfavouring the integration of the system in the daily life of participants, and suggestions on how the system could be improved has been gained. The thesis thus confirmed and highlighted the key role of user experiences in the design process of new mHealth approaches, and provided insights on how to develop and evaluate mobile health approaches from the user perspective. Based on the results of the user evaluation, two possible directions for the future of eHISS have been developed. We further conclude that programs and initiatives must be guided by robust strategies to overcome existing barriers for implementation. Like all digital health interventions, the presented eHISS system is not a silver bullet and has significant limitations, but taking the requirements discussed in the thesis into consideration we believe that systems developed based on the eHISS experiences in future can make a real impact on health service delivery and disease response

Interactive radio’s promising role in climate information services: Farm Radio International concept paper

This paper focuses on how interactive radio programming can increase the reach of weather and seasonal climate information and related advisory services. In doing so, they can enhance small-scale farmers’ capacity to make optimal decisions and manage risks based on a better understanding of probabilistic seasonal forecasts. The objective is to outline strategy that could vastly and affordably expand the number of small-scale farmers that are reached by and benefit from weather and climate information and related advisory services. Building on Farm Radio International’s (FRI) pioneering African Farm Radio Research Initiative (AFRRI), we assess the opportunities for interactive radio to provide integrated climate and advisory information while increasing farmers’ equitable access to salient and legitimate programming. We describe a number of practical strategies that can be used to make radio-based climate communication interactive, outline elements of a successful interactive radio service targeting rural communities, and discuss costs and other issues required for sustainability

Integration of Internet and Telecommunications- An Architecture for Hybrid Services

In this article, we propose an architecture for hybrid services, i.e., services that span many network technologies, such as the Public Switched Telephone Network (PSTN), cellular networks and networks based on the Internet Protocol (IP). These services will play an important role in the future because they leverage on the existing infrastructures, rather than requiring new and sophisticated mechanisms to be deployed. We explore a few issues related to hybrid services and propose a platform, as well as a set of components, to facilitate their creation and deployment. The existing infrastructure is only required to generate specific events when requests for hybrid services are detected. We present the design of a service layer, based on Java, that handles the treatment of these special requests. Our service layer is provided with a set of generic components realized according to the JavaBeans model. We illustrate the strength of our architecture by discussing two hybrid-service examples: a calendar service and a call forwarding service

Self service technology : an overview of existing research

The purpose of this working paper is twofold. First the paper presents a review of the literature on self service technology (SST). The review categorizes the literature based on dependent variables studied in existing research. The review finds that most of the studies have focused on antecedents of attitude/intention/usage of SST, satisfaction with SST, and loyalty to SST. Also, the antecedents to each of the three main dependent variables are systemized in the review. The review shows that existing literature on SST hardly include moderating variables in the models tested. None of the articles aiming to explain loyalty to SST have included potential moderating effects in the models tested. The paper also gives an overview of potential dimensions for categorization of SST. Only a few of the articles reviewed gives insight into such dimensions. Given the limited focus on dimensions for categorization of self service technologies, the second purpose was to study how various channels vary along more general channel dimensions. A brief review of such dimensions is reported, and an exploratory study among students at Norwegian School of Economics and Business Administration (NHH) is conducted illustrating how 11 channels are perceived along 16 dimensions. The results show significant differences between the channels in how they are perceived along all of the 16 dimensions studied. Finally, based on the review and the exploratory study conducted, some directions for future research are suggested

An empirical, in-depth investigation into service creation in H.323 Version 4 Networks

Over the past few years there has been an increasing tendency to carry voice on IP networks as opposed to the PSTN and other switched circuit networks. Initially this trend was favoured due to reduced costs but occurred at the expense of sacrificing the quality of the voice communications. Switched circuit networks have therefore remained the preferred carrier-grade voice communication network, but this is again changing. The advancement in improved quality of service (QoS) of real-time traffic on the IP network is a contributing factor to the anticipated future of the IP network supplying carrier-grade voice communications. Another contributing factor is the possibility of creating a new range of innovative, state-of-the-art telephony and communications services that acquire leverage through the intelligence and flexibility of the IP network. The latter has yet to be fully explored. Various protocols exist that facilitate the transport of voice and other media on IP networks. The most well known and widely supported of these is H.323. This work presents and discusses H.323 version 4 service creation. The work also categorises the various H.323 services and presents the mechanisms provided by H.323 version 4 that have facilitated the development of the three services I have developed, EmailReader, Telgo323 and CANS
