Ideal Matunda Ltd: Investment Challenges
No full textA case study done on Ideal Matunda Ltd by Chege Gerald W. Assistant Professor of Information Systems & Machoka Phillip Gichaba Lecturer of Information Systems and Technology, school of Science and Technology in USIU – Africa.Sitting at her office, the CEO of Ideal Matunda Ms. Beth Mwangi was preparing for the next board meeting which was coming up the following week, 9th Thursday, September 2010. She was contemplating on issues she had discussed in meetings with the finance manager earlier that week and the operations manager that day. She needed to make a decision to present to the board, whether to invest in an Enterprise Resource Planning (ERP) system or another production plant for refining oil. . The Operations Manager was passionately rooting for the oil refinery plant while the Finance Manager was convinced the ERP was the priority to improve on organizational operations and to manage costs. Having spent 4 years in the fruit business sub-sector, Ms. Mwangi looked back and realized she needed to move Ideal Matunda Ltd. to the next level. One option would be to diversify the business into refined avocado oils for local as well as international markets. The other would be to improve on operational efficiency of the company through the use of Information and Communications Technology (ICT). The later would cut down costs, enhance its competitiveness and differentiate it from its competitors in the fruit sector. The company could not implement both options due to financial constraints. Ms. Mwangi wondered whether she should invest in another production system for refined oils to diversify, or in ICT to improve on operational efficiency
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
E-Learning: USIU’s Experience
No full textA Journal article by Dr. Gerald W. Chege,an Assistant Professor, Information Systems & Technolog at United States International UniversityDistance education / distance learning, is a field of education that focuses on the pedagogy, technology, and instructional systems design that are effectively incorporated in delivering education to students who are not physically "on site" to receive their education.
Instead, teachers and students may communicate asynchronously (at times of their own choosing) by exchanging printed or electronic media, or through technology that allows them to communicate in real time (synchronously).
Distance education courses that require a physical on-site presence for any reason including the taking of examinations is considered to be a hybrid or blended course or program.
Types of Distance Education Courses
Correspondence conducted through regular mail Internet conducted either synchronously or asynchronously
Telecourse/Broadcast where content is delivered via radio or television CD-ROM where the student interacts with computer content stored on a CD-ROM
PocketPC/Mobile Learning where the student accesses course content stored on a mobile device or through a wireless serve
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
