Northern Caribbean University is a private, liberal-arts institution owned and operated by the Jamaica Union Conference and the Atlantic Caribbean Union Mission of Seventh-day Adventists, and is located in Jamaica. With its main campus only 2 miles south of Mandeville town, in Manchester, and three other campuses situated in Kingston, Montego Bay and St. Ann, this university offers a number of professional, pre-professional and vocational programmes in a spiritually wholesome and aesthetically pleasing atmosphere. Established in 1907, NCU currently enjoys an average yearly enrolment of over five thousand students, from up to 35 countries, and is the world’s largest English speaking Seventh-day Adventist tertiary institution.

Numerous hypotheses on the evolution of Neotropical biodiversity have stimulated research to provide a better understanding of diversity dynamics and distribution patterns of the region. However, few studies integrate molecular and morphological data with complete sampling of a Neotropical group, and so there has been little synthesis of the multiple processes governing biodiversity through space and time. Here, a total-evidence phylogenetic approach is used to reconstruct the evolutionary history of the butterfly subgenus Heraclides. We used DNA sequences for two mitochondrial genes and one nuclear gene and coded 133 morphological characters of larvae and adults. A robust and well-resolved phylogeny was obtained using several analytical approaches, while molecular dating and biogeographical analyses indicated an early Miocene origin (22 Mya) in the Caribbean Islands. We inferred six independent dispersal events from the Caribbean to the mainland, and three from the mainland to the Caribbean, and we suggest that cooling climates with decreasing sea levels may have contributed to these events. The time-calibrated tree is best explained by a museum model of diversity in which both speciation and extinction rates remained constant through time. By assessing both continental and fine-scale biodiversity patterns, this study provides new findings, for instance that islands may act as source of diversity rather than as a sink, to explain spatio-temporal macroevolutionary processes within the Neotropical region. © The Willi Hennig Society 2014.

Deception and dishonesty in online exams are believed to link to their unmonitored nature where users appear to have the opportunity to collaborate or utilize unauthorized resources during these assessments. The primary goal of this study was to investigate the deterrent effect of Webcam-based proctoring on misconduct during online exams. This study involved an experimental design in comparing an experimental group and a control group. Both groups attended the same course, used the same e-learning system, with the same instructor, and took the same set of online exams. One group was monitored by a Web-based proctor while the other was not monitored. The results indicated no statistically significant difference between the scores of the two groups, although the non-proctored group had slightly higher scores. There was a statistically significant difference found on the time taken to complete the online exams where the proctored group used significantly less time to complete their exams. The results of a post-experiment survey indicated that those who were not proctored perceived to have experienced greater levels of opportunity to engage in misconduct than those who were monitored by a Web-based proctor. © 2015 Elsevier Ltd.

Purpose - The purpose of this paper was to examine the impact of the e-library on the usage of library resources at Northern Caribbean University. The objective was also to determine whether or not it is worthwhile to continue to invest in electronic resources in a period of declining library budgets and easy access to electronic resources via the internet. Design/methodology/ approach - Data were collected from library statistical reports as well as from a survey administered to students and faculty on both the main and extension campuses over a four-week period. The population studied in the survey was 280 faculty members and 5,340 students. Of this number, a stratified random sample of 50 faculty members and 200 students was selected. Findings - The study shows that the provision of e-library resources has increased overall usage of library materials as patrons continue to use print resources in tandem with electronic versions. The study also found that the electronic library resources are helpful to patrons and play an important role in enhancing access to library resources necessary for quality research papers and academic excellence on a whole. Originality/value - It is hoped that the findings of this paper will serve to assist the librarians and faculty at Northern Caribbean University and other similar institutions in selecting and acquiring the most appropriate format of information resources that will both satisfy the needs of their library users and fit within their library budget. Recommendations for improving the e-library service include continuous collaboration between librarians and faculty in selecting and acquiring the most appropriate format of resources to support the curriculum and satisfy the users' needs, constant marketing of the resources and on-going training in their use, and periodic assessment of the collection to ensure quality and competitiveness in light of other readily available electronic resources on the internet. © Emerald Group Publishing Limited.

The purpose of this case-study is to narrate a secondary science teacher's experience of his professional development (PD) education and training in innovative technologies (IT) in the context of engaging students in environmental research projects The sources from which the narrative is derived include (1) the science teacher's reflective reports during three summer institute programs and (2) the science teacher's reflective reports while subsequently engaging students in IT-embedded environmental research projects in his classroom. The science teacher's explanations for changes in students' perception of their IT fluency illuminate his personal narrative. The science teacher attributed his growth and significant changes in students' perceptions of their IT fluency to the following mechanisms: (a) a personal commitment to developing his own and his students' IT abilities in the context of doing environmental research projects, and (b) an increase in class time devoted to science education due to school-time scheduling policy. The study implies that immersive professional development opportunities have the potential to produce significant increases in students' perceptions of their IT fluency. © 2011 Springer Science+Business Media, LLC.

Bauxite inputs into the Bayer process at a Jamaican refinery were found to contain approximately 0.4% inorganic carbon (or 3.2% CaCO3) and 0.2% organic carbon. Thermal treatment or heating of 10 g bauxite samples for 30 min at temperatures ranging from 300 to 1000 C was shown to significantly reduce levels of both organic (up to 93%) and inorganic carbon (up to 100%); however, there was an accompanying noticeable decrease in solubility of bauxite ore calcined at temperatures above 300 C based on predigestion alumina/caustic (A/C) ratios in spent liquor at 99 C. X-ray diffraction and X-ray database (XDB) spectral analysis of the calcined bauxite (>600 C) demonstrated the appearance of corundum (α-alumina), a form of aluminum oxide much less soluble than boehmite or gibbsite. © 2012 American Chemical Society.
