Crisis Management: Unveiling Information And Communication Technologies’ Revamped Role Through The Lens Of Sub-Saharan African Countries During Covid-19, Ruthbetha Kateule, Egidius Kamanyi, Mahadia Tunga
The African Journal of Information Systems
The management of COVID-19 pandemic has revealed inefficiencies in coordinating global response, particularly in African countries. Therefore, creating an urgent need to examine the literature on Information and Communication Technologies (ICT) in crisis management to appreciate its contextual role. Employing a systematic review, using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA), this paper critically assessed the extent of the use of ICT in crisis management in Africa’s response to COVID-19 to reconstruct its resilience against future crises. Findings indicate that while countries with limited ICT infrastructure faced considerable challenges in utilizing ICT solutions in COVID-19 management, countries …
Building And Using Digital Libraries For Etds, Edward A. Fox
Building And Using Digital Libraries For Etds, Edward A. Fox
The Journal of Electronic Theses and Dissertations
Despite the high value of electronic theses and dissertations (ETDs), the global collection has seen limited use. To extend such use, a new approach to building digital libraries (DLs) is needed. Fortunately, recent decades have seen that a vast amount of “gray literature” has become available through a diverse set of institutional repositories as well as regional and national libraries and archives. Most of the works in those collections include ETDs and are often freely available in keeping with the open-access movement, but such access is limited by the services of supporting information systems. As explained through a set of …

Turkish Journal of Electrical Engineering and Computer Sciences
Everyday information systems collect a different kind of process instances of a business flow. As time goes on, the size of the collected data builds up speedily and constitutes a huge amount of data. It is a very challenging task to obtain valuable information and features of processes from such big data. Considering in advance, the trend and different features of the ongoing process are essential. Especially, time management is crucial in designing and conducting business processes. In this article, a novel process miner algorithm is proposed for time prediction, named time-oriented İnteractive process miner (T-IPM), which predicts the remaining …
Passenger Scoring For Free-Pass Promotion In Public Transportation, Ufuk Demi̇r Alan, Derya Bi̇rant
Passenger Scoring For Free-Pass Promotion In Public Transportation, Ufuk Demi̇r Alan, Derya Bi̇rant
Turkish Journal of Electrical Engineering and Computer Sciences
The focus of promotions targeted to increase the use of public transportation concentrates on increasing the attractiveness of it, particularly by decreasing transportation fares. To serve that purpose, this paper proposes a novel passenger scoring model, namely RFLT (recency, frequency, loyalty, and time), for offering a free-pass promotion in public transportation. It presents the comparison results of RFLT and wRFLT (weighted version) using a real-world dataset obtained by a near field communication (NFC) mobile payment application. The experimental results show that the w-RFLT model provides a more balanced score distribution than the RFLT model, and the frequency parameter (F), among …
The Concept Of Representation Capability Of Databases And Its Application In Is Development, Lishuan Qin, Junkang Feng
The Concept Of Representation Capability Of Databases And Its Application In Is Development, Lishuan Qin, Junkang Feng
Journal of International Technology and Information Management
The representation capability of an information system in general and a database in particular seems an important and yet elusive concept, which is concerned with, in our view, how a database ever becomes capable of representing real-world objects accurately or otherwise. To explore how to approach and then define this concept, we explore what is meant and required by the statement that a database connection (i.e., a connection between database constructs such as entities in an Entity-relationship (ER) diagram and relations in a relational schema that are made available by a database) refers to, represents and accurately represents a …
Analyzing Methods Of Network Topologies Based On Chordal Rings, Damian Ledzinski, Sandra Smigiel, Lukasz Zabludowski
Analyzing Methods Of Network Topologies Based On Chordal Rings, Damian Ledzinski, Sandra Smigiel, Lukasz Zabludowski
Turkish Journal of Electrical Engineering and Computer Sciences
This paper presents a methodology for the transmission properties research of networks patterned according to the third-degree chordal graphs. When designing and analyzing ICT systems, it is vital to consider the topology of network components. The telecommunication network structure can be described by a graph. Computing modes or specialized computers are the vertexes and the edges are bidirectional, independent transmission channels that represent the connected nodes. The algorithm is potentially useful for the determination of the impact of diameter and an average path length of the chordal rings on the properties of the transmission network. It is also useful for …
Justification Of Investment In It Systems, Aidan Farrell
Justification Of Investment In It Systems, Aidan Farrell
The ITB Journal
For a company, capital investment of any sort is weighed up before a decision is made to invest. It is. true that the vast majority of investments for companies can be quantified financially. Investment in Iriformation Technology (IT) and Information Systems (IS) however has proved more complex than other investments as there are ·a large amount of intangible and non-financial benefits associated with this area of expenditure. Investments are traditionally rationalised by outweighing the costs and the benefits. The indirect costs associated with the deployment of IT/IS are equally difficult to put a measure on and hence the traditional methods …
Right Now Is The Wrong Time: And Other Considerations When Presenting Security Warnings, Brock Johanson, Bonnie Anderson
Right Now Is The Wrong Time: And Other Considerations When Presenting Security Warnings, Brock Johanson, Bonnie Anderson
Journal of Undergraduate Research
Neuro Information Security (NeuroIS) focuses on the use of neurological measurements to improve the security of information systems. The BYU NeuroIS lab uses neurological tools and measurements to examine factors that affect security outcomes. Previous work has focused on various factors such as dual task interference (DTI), threat assessment, as well as factors such as habituation and generalization, which have become focus streams of research. The primary point of failure in most security related incidents tends to be users themselves. As such, anything that can be used to overcome neurobiological phenomenon such as those listed above can ultimately lead in …
