Factors influencing investors to invest in equities as opposed to bonds in the banking industry in Kenya
No full textThis Research project investigated the factors influencing the investors to invest in equities as opposed to Bonds in Banking industry in Kenya. Development of bonds market widens the financing options for firms and enables the government to shift its domestic debt to longer-term securities. However, development of bonds market requires that certain conditions be in place. These include a developed money market, wider participation and protection of investors, reduced information asymmetry and an efficient trading system. This would boost the market micro structure and facilitate development of the marke
Measuring Levels of End-Users’ Acceptance and Use of Hybrid Library Services
No full textThis study concerns the adoption of Information Communication Technology (ICT) services in
libraries. The study collected 445 usable data from university library end-users using a cross-
sectional survey instrument. It develops, applies and tests a research model of acceptance and
use of such services based on an existing UTAUT model by Venkatesh, et al. (2003). Results
show that ‘relevance’ and ‘social influence’ have significant effects on intentions to use e-library
services. Results further show that university communities in Uganda are inclined to use
electronic library services due to social demands, relevancy of services, available facilitating
conditions and benefits they expect from the services. Most importantly, the Service Oriented
Unified Theory of Acceptance and Use of Technology (SOUTAUT) model explains 57% of
variance towards acceptance and use of e-library services
Evaluation of Software Visualization Tools
No full textMany software visualization (SoftVis) tools are continuously be-
ing developed by both researchers as well as software development
companies. In order to determine if the developed tools are effec-
tive in helping their target users, it is desirable that they are exposed
to a proper evaluation.
Despite this, there is still lack of a general guideline on how these
evaluations should be carried out and many of the tool developers
perform very limited or no evaluation of their tools. Each person
that carries out one evaluation, however, has experiences which, if
shared, can guide future evaluators. This paper presents the lessons
learned from evaluating over 20 SoftVis tools with over 90 users
in five different studies spread on a period of over two years. The
lessons covered include the selection of the tools, tasks, as well as
evaluation participants. Other discussed points are related to the
duration of the evaluation experiment, its location, the procedure
followed when carrying out the experiment, as well as motivation
of the participants. Finally, an analysis of the lessons learned is
shown with the hope that these lessons will be of some assistance
to future SoftVis tool evaluators
Acceptance and use of electronic library services in ugandan universities
No full textUniversity libraries in Developing Countries (DCs), hampered by developmental problems, find it hard to provide electronic services. Donor communities have come in to bridge this technology gap by providing funds to university libraries for information technology infrastructure, enabling these university libraries to provide electronic library services to patrons. However, for these services to be utilized effectively, library end-users must accept and use them. To investigate this process in Uganda, this study modifies "The Unified Theory of Acceptance and Use of Technology" (UTAUT) by replacing "effort expectancy" and "voluntariness" with "relevancy", "awareness" and "benefits" factors. In so doing, we developed the Service Oriented UTAUT (SOUTAUT) model whose dependent constructs predict 133% of the variances in user acceptance and use of e-library services. The study revealed that relevancy moderated by awareness plays a major factor in acceptance and use of e-library services in DCs
Defining visualization operations for temporal cartographic animation design
No full textCartographic animation has emerged as a potentially effective visualization technique that has an intuitive power in representing dynamic geographical phenomena through its ability to show interrelations amongst geospatial data’s components, location, attribute and time. Whereas cartographic animation has prominently featured in communicating geospatial information, their use as tools for visual exploration has been hampered by lack of the necessary functionality that is capable of allowing users to interact with the dynamic display. In this paper, we outline an approach that defines visualizations operations or basic visual actions that implement a viewer’s task of exploration and characterization of geospatial structures in data or phenomena. The defined operations go along to reinforcing the quest in enabling users to perceive relationships and be able to manipulate geospatial data using more efficient visual tools while keeping low on cognitive demands
