The impact of cybercrime on e-banking: A proposed model
Full text linkEach day cybercrime attacks are getting more frequent, dangerous and sophisticated. In 2016 the FBI’s Internet Crime Complaint Center received 1,408,849 complaints and a reported loss of $4.63 billion. The concept of cybercrime is complex, and as such the drive to overcome the problem is very difficult. However, the continual escalation of cybercrimes can have a negative impact on businesses and by extension the economies of countries. As a result, it is imperative that measures be identified to overcome the problem. Hence, this study seeks to propose a research model which can be used to evaluate the significance of cybercrime in deterring the use of e-banking in the financial sector. It is hoped that the proposed research model will influence other researchers to conduct empirical research in their context
Fatores-chave do processo de maturidade nas empresas caribenhas de língua inglesa
Full text linkThe information system (IS) community has been struggling with the delivery of low quality systems. Software process improvement (SPI) has been accepted as one of the remedies to overcome this problem, with process maturity being a key element. However, most studies on process maturity and the determinants of IS quality have been conducted in large firms in developed countries. This study assessed the key determinants of process maturity in small software development firms in the English-speaking Caribbean (ESC). Using the established practices in the capability maturity model integration (CMMI) as the baseline for the analysis, it was found that project monitoring & control, and verification & validation are key determinants of process maturity in the ESC. These findings can assist IS professionals in their quest to produce higher quality software products, as well as provide a platform for further refinement of the proposed research model by IS researchers.La comunidad de sistemas de información (SI) ha sufrido con la producción de sistemas de baja calidad. La mejora del proceso de softwares (SPI) fue aceptada como uno de los paliativos para superar este problema, siendo la madurez del proceso un elemento clave; sin embargo, la mayoría de los estudios sobre la madurez procesal y los determinantes de la calidad IS fueron realizados en grandes empresas, en países desarrollados. Este estudio evaluó los principales determinantes de la madurez en los procesos en pequeñas empresas de desarrollo de software, en el Caribe, de lengua Inglesa (ESC). Usando las prácticas establecidas en la integración del modelo de madurez de la capacidad (CMMI), como la línea base para el análisis, se verificó que el monitoreo y control del proyecto, junto con la verificación y validación, son los principales determinantes de la madurez procesal en las ESC. Estos descubrimientos pueden ayudar a los profesionales de IS, en su búsqueda por producir productos de software de calidad superior, y también proporcionar una plataforma para el refinamiento del modelo de investigación, propuesto por investigadores del área de IS.A comunidade de sistemas de informação (SI) tem sofrido com a produção de sistemas de baixa qualidade.

The Adoption of Software Process Improvement Programs in the English-Speaking Caribbean
Full text linkManaging and improving the processes used to develop software products is widely accepted as one of the remedies to overcome the problem of poor quality systems being delivered. As a result, the IS community has adopted several software process improvement (SPI) programs. The tenets of these programs are grounded in the belief that a mature development process can increase the likelihood of producing high quality software products with the requisite requirements which should add business value. However, small firms in developing countries like the English-speaking Caribbean (ESC) are not aware nor adopting these SPI programs because they are seen as costly, time consuming and disruptive; hence, not realizing the potential benefits. This study examined the awareness, adoption and benefits of SPI programs in ESC software development firms. The result found that a slight majority (54.5%) of firms in the region are aware of SPI programs, with only 20% of those who are aware using any form of SPI programs in the development of software. These findings reinforces the need for SPI training in the ESC to articulate the compelling need for a change towards the adoption and use of SPI programs in software development
Gender Difference in the Knowledge and Adoption of Educational Technology by Faculty: The Case of a Business School in Jamaica
Full text linkThis paper seeks to inform our understanding of the role played by gender in the process of educational technology adoption in a business school in Jamaica. Gender difference studies in educational research are becoming popular but there are few studies in this domain in higher education, especially with respect to faculty. The research examines the expertise of faculty in educational technologies, as well as their adoption and non-adoption in using these technologies in teaching and learning. The study found that males accounted for 62% of faculty exhibiting high levels of expertise in educational technologies in comparison to 38% for the females. The level of adoption for males was statistically higher than females. In addition, the main enhancer was found to be “educational technologies have the potential to enhance teaching and learning” and the main barriers, “there is no reward from administration for using educational technologies in teaching”. The study reinforces the need for further research to assist with the formulation and implementation of the national policy on using educational technologies to enhance teaching and learning in Jamaic
7P. A Preliminary Study of the Use of Software Process Improvement Initiatives in Jamaica
Full text linkDespite the acknowledged strides that information and communications technologies (ICT) have made, the information systems (IS) community has been plagued with the delivery of low quality information systems (IS). This phenomenon gave rise to a variety of software process improvement (SPI) interventions, aimed at reducing variability in the software production process, as a precursor to improving IS quality. However, SPI initiatives have targeted fairly large organizations and SPI research has been conducted mainly in developed countries, and very little in developing countries and smaller organizations such as those in Jamaica and the English-speaking Caribbean. We sought in this research to ascertain the level of awareness and intention to use SPI programs in Jamaican software development firms. Preliminary indications of our study revealed that a large majority of these firms are not aware of SPI programs; neither do they intend to adopt any form of SPI effort in the near future. Our findings provided the basis to support the claim for future research to explore the underlying causes for this lack of awareness and non-adoption of SPI programs among Jamaican firms
Understanding Mobile Internet Diffusion: The Case of Jamaica
Full text linkWorldwide it is estimated that there are over 5.3 billion mobile subscribers of which almost 4 billion are in the developing world (ITU, 2010b). For developing countries, the digital divide in terms of access has begun to close with the flow of digital information through core mobile services (e.g. voice, SMS) even in the poorest of countries. This offers the potential to capitalize on the economic benefits and improvements in quality of life that can come about with improved communications (Abraham, 2007; Rashid & Elder, 2009). In addition the rapid spread of this innovation in developing countries also paves the way for greater connectivity and access to the Internet via mobile devices and diffusing of value-added services such as mobile banking. However, uptake of more advanced mobile services other than basic telephony has lagged behind expectations, even for trendsetters like Finland (Bouwman et al., 2008). In developing countries the lag may be due in part to the affordability of access and the underdeveloped nature of basic services such as Internet access and mobile banking. However,where these services are more affordable and accessible (and increasingly so) it is important to investigate why persons have been slow to adopt mobile Interne
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
