Ict For Poverty Alleviation In Pacific Island Nations: Study Of Icts4d In Fiji, Deogratias Harorimana, Opeti Rokotuinivono, Emali Sewale, Fane Salaiwai, Marica Naulu, Evangelin Roy
Dr Deogratias Harorimana
ICT for Poverty Alleviation in Pacific Island Nations: Study of ICTs4D in Fiji There has been a vague and little knowledge on the role or potential of Information and Communications Technologies (ICTs) in relation to addressing poverty in Fiji. This may be probably due to the newness of the technology in the South Pacific Region as a whole but also probably due to the fact that only 9.7% of the current Fiji 931,000 populations are internet users (ITC Figures 2011). This paper reports on finding how ICTs is contributing towards poverty alleviation in Fiji. On the basis of reviewed best …

Evaluating The Impact Of Ehr On Clinical Reasoning Performance: A Ttf Perspective, Matthew Wills, Omar El-Gayar, Amit Deokar
Evaluating The Impact Of Ehr On Clinical Reasoning Performance: A Ttf Perspective, Matthew Wills, Omar El-Gayar, Amit Deokar
Amit Deokar
The proliferation of Electronic Health Records (EHR) as a backbone for healthcare delivery necessitates adequate tools for evaluating and improving the efficacy of such investments particularly as it relates to clinical reasoning performance. However, a thorough review of the literature indicates lack of a tested, validated instrument for evaluating and predicting the impact of EHR use on clinical reasoning performance. Despite successful application to a variety of other industries, TTF has not been adequately adapted to healthcare, EHR technology or the clinical reasoning task. Accordingly, the objectives of this research are to: 1) produce a valid instrument with diagnostic and …
A Business Model Perspective For Icts In Public Engagement, Mutaz M. Al-Debei, Panagiotis Panagiotopoulos, Guy Fitzgerald, Tony Elliman
A Business Model Perspective For Icts In Public Engagement, Mutaz M. Al-Debei, Panagiotis Panagiotopoulos, Guy Fitzgerald, Tony Elliman
Dr. Mutaz M. Al-Debei
Public institutions, in their efforts to promote meaningful citizen engagement, are increasingly looking at the democratic potential of Information and Communication Technologies (ICTs). Previous studies suggest that such initiatives seem to be impeded by socio-technical integration barriers such as low sustainability, poor citizen acceptance, coordination difficulties, lack of understanding and failure to assess their impact. Motivated by these shortcomings, the paper develops and applies a business model perspective as an interceding framework foranalysisandevaluation. The underlying principlebehind thisapproachisthatit isnottechnology per se which determines success, but rather the way in which the business model of the technological artifact is configured and employed …
Issues In Human Capital Development : Lessons For Public Administration And Governance, Deogratias Harorimana Mr
Issues In Human Capital Development : Lessons For Public Administration And Governance, Deogratias Harorimana Mr
Dr Deogratias Harorimana
With few minerals or other natural resources, Rwanda believes that she can still achieve her ambitions by investing in human capital - her unique resource. If this ambition can be achieved, then is this the next role model for international development? We used a case study design and analysis methods to examine development models used elsewhere in recent decades, using both qualitative and quantitative data on Rwanda to establish the comparative advantages in relation to Singapore’s economic development model. The implications for international development are that (1) an effective human capital development strategy should be inclusive enough to respond to …
Rfid-Enabled Inventory Control Optimization: A Proof Of Concept In A Small-To-Medium Retailer, H. Dane, Katina Michael, S. F. Wamba
Rfid-Enabled Inventory Control Optimization: A Proof Of Concept In A Small-To-Medium Retailer, H. Dane, Katina Michael, S. F. Wamba
Dr Samuel Fosso Wamba
This study examines the impact of radio-frequency identification (RFID) technology on the inventory control practices of a small-to-medium retailer using a proof of concept (PoC) approach. The exploratory study was conducted using a single case study of a hardware retailer stocking 5000 product lines provided by 110 active suppliers. To analyze the present mode of operation, procedural documents, semi-structured interviews and a participant observation was conducted. The basis for the proof of concept was a future mode of operation using a quasi-experimental design. Results indicate that in a small-to-medium retail environment, RFID technology could act as a loss prevention mechanism, …
Ontology-Based Information Extraction For Analyzing It Services, Amit Deokar, Sagnika Sen
Ontology-Based Information Extraction For Analyzing It Services, Amit Deokar, Sagnika Sen
Amit Deokar
Service Level Agreements (SLA) for multi-service Information Technology (IT) outsourcing contracts contain vast amounts of textual information. The SLAs provide details about a specific service, Key Performance Indicators (KPI) to measure its performance; as well as process elements, such as activities, events, and resources that are integral in achieving performance goals. However, KPIs and the process elements may be interrelated. The knowledge of such interrelationships is often tacitly present in the SLAs. The aim of our research is to extract this hidden information from IT service contracts and analyze them to empower customers of IT services to make better performance …
Learning And Forgetting In Maintenance Outsourcing, Hakan Tarakci, Sunantha Teyarachakul, Kwei Tang
Learning And Forgetting In Maintenance Outsourcing, Hakan Tarakci, Sunantha Teyarachakul, Kwei Tang
Hakan Tarakci
We study the effects of learning and forgetting on maintenance outsourcing in this paper. This is an extension of the paper by Tarakci et al. (2009), which analyzed the effects of learning on maintenance outsourcing. In our model, a manufacturer offers a short-term outsourcing contract, where payment includes a fixed value along with cost subsidization for each preventive maintenance activity, to an external contractor. The contractor schedules and performs preventive maintenance activities as well as repairs the system if there is a failure. We consider two types of learning: natural learning and learning by costly efforts. We then analyze the …
On The Problem Of Production Deadline And Maintenance Outsourcing, Sharafali Moosa, Hakan Tarakci
On The Problem Of Production Deadline And Maintenance Outsourcing, Sharafali Moosa, Hakan Tarakci
Hakan Tarakci
In this paper we consider a production-maintenance problem in which a buyer and a supplier have already entered into a contractual relationship for a firm delivery date. Our focus is on the production-related decisions of the supplier rather than the nature of the contract itself. We assume that production rate is actually constant as long as the system is up and running but randomness arises in production due to downtimes as a result of unpredictable failures (breakdowns) and scheduled preventive maintenance activities. Production maintenance is outsourced. As production output is random due to unreliable production facilities, the supplier needs to …
The Convergence In Workers’ Skill Levels Under Learning And Forgetting: The Fixed-Point-Property Approach, Sunantha Teyarachakul, Dogan Comez, Hakan Tarakci
The Convergence In Workers’ Skill Levels Under Learning And Forgetting: The Fixed-Point-Property Approach, Sunantha Teyarachakul, Dogan Comez, Hakan Tarakci
Hakan Tarakci
This paper presents a study on the convergence of workers’ skill levels under learning and forgetting in processing time in a batch-manufacturing environment. The convergence properties are examined under assumptions of an infinite horizon, a constant demand rate, and a fixed lot size. Our work extends the convergence results of Teyarachakul, Chand, and Ward (2008) beyond Globerson and Levin’s (1987) exponential forgetting function and Wright’s (1936) learning curve to more general classes of learning and forgetting functions. We also discuss why early papers other than Teyarachakul, Chand, and Ward (2008) did not find other types of long-term behaviors beyond convergence …
