Visualization and visual analytics of geospatial data for psychological treatment

Dissertation submitted in partial fulfilment of the requirements for the degree of Master of Science in Geospatial TechnologiesCurrent location-tracking solutions, along with general advances in software (e.g., development frameworks, visualization libraries) and hardware (e.g., cloud computing, mobile devices), make it increasingly easy to capture and store geospatial data to be exploited in various application areas. In this dissertation, we study the possibilities of visualization techniques and visual analytics of geospatial (user) data with the aim of helping/improving therapies in the realm of psychological health. To this aim, a web-based visualization application was created as part of a larger ecosystem of applications created by GEOTEC, including a mobile app to systematically capture user’s geospatial data (i.e., GPS coordinates), and a metrics analytical platform, which is capable of storing captured data and performing useful analysis/calculations. The visualization tool was developed to support therapists to make informed decisions pertinent to psychological illness depression interventions, by allowing them to visually inspect, compare, and analyze captured and processed data from monitored patients. Next to determining what visual elements of the visualization tool best suited the needs of the case study, a quantitative and qualitative evaluation was performed with therapists, in order to measure the resulting usefulness of the tool, find out the drawbacks for further improvement, and to generate ideas for future work and further applications in psychological health. As a result, the visualization tool was generally found to be useable (SUS score of 86.5625), useful for therapists to help during and to determine their therapy, and various useful extensions and further application areas were discovered. Based on the result, we can conclude that the tool may indeed become a beneficial mechanism for psychological intervention in real-world settings

Developing Mobile Application for Land Value Capture Scheme to Finance Urban Rail Transit Projects

Land value capture (LVC) has shown great potential in financing urban rail system infrastructure, such as transit-oriented development (TOD). However, the government of Indonesia has not tapped this potential in order to close its infrastructure financing gap. This study aims to determine the incremental rate captured through a tax-based LVC mechanism and develop a property market-based mobile application to implement the scheme, with six TOD areas in seven stations of the Mass Rapid Transit (MRT) Jakarta Phase I project as the case study. This research used literature and benchmarking studies to collect data, followed by the calculations of the transport premium, total value increment, and value capture rate for the betterment tax implementation to obtain its research objectives. The results showed that a 5.82% value capture rate could recover 53.8% of the government's initial investment for the project. Based on that figure, betterment tax rates of 0.3% and 0.1% are proposed for residential properties within the radius of 100-400 m and 400-700 m from transit stations, respectively. Meanwhile, 2.5% and 2.4% tax rates are proposed for commercial properties within the radius of 0-300 m and 300-600 m, respectively. Furthermore, the activity workflow for a mobile application in which the government can issue tax invoices and taxpayers can make payments is also proposed to facilitate the implementation of LVC as an alternative source to finance TOD projects

Wicked Problems and Gnarly Results: Reflecting on Design and Evaluation Methods for Idiosyncratic Personal Information Management Tasks

This paper is a case study of an artifact design and evaluation process; it is a reflection on how right thinking about design methods may at times result in sub-optimal results. Our goal has been to assess our decision making process throughout the design and evaluation stages for a software prototype in order to consider where design methodology may need to be tuned to be more sensitive to the domain of practice, in this case software evaluation in personal information management. In particular, we reflect on design methods around (1) scale of prototype, (2) prototyping and design process, (3) study design, and (4) study population

Analysis methodology for flow-level evaluation of a hybrid mobile-sensor network

Our society uses a large diversity of co-existing wired and wireless networks in order to satisfy its communication needs. A cooper- ation between these networks can benefit performance, service availabil- ity and deployment ease, and leads to the emergence of hybrid networks. This position paper focuses on a hybrid mobile-sensor network identify- ing potential advantages and challenges of its use and defining feasible applications. The main value of the paper, however, is in the proposed analysis approach to evaluate the performance at the mobile network side given the mixed mobile-sensor traffic. The approach combines packet- level analysis with modelling of flow-level behaviour and can be applied for the study of various application scenarios. In this paper we consider two applications with distinct traffic models namely multimedia traffic and best-effort traffic

Public Service Delivery: Role of Information and Communication Technology in Improving Governance and Development Impact

The focus of this paper is on improving governance through the use of information and communication technology (ICT) in the delivery of services to the poor, i.e., improving efficiency, accountability, and transparency, and reducing bribery. A number of papers recognize the potential benefits but they also point out that it has not been easy to harness this potential. This paper presents an analysis of effective case studies from developing countries where the benefits have reached a large number of poor citizens. It also identifies the critical success factors for wide-scale deployment. The paper includes cases on the use of ICTs in the management of delivery of public services in health, education, and provision of subsidized food. Cases on electronic delivery of government services, such as providing certificates and licenses to rural populations, which in turn provide entitlements to the poor for subsidized food, fertilizer, and health services are also included. ICT-enabled provision of information to enhance rural income is also covered
