Effects of Bayluscide on Mitosis in Root Tip Cells of Allium cepa L.
Get PDFA common practice among farmers is to spray pesticides on crops in order to protect them from herbivores to have an abundant production of crops. The purpose of this study was to find out the effects of Bayluscide on cell division in root tip cells of onions (Allium cepa). The study uses the Randomized Complete Block Design (RCBD), consisting of one control group and four experimental groups that were replicated thrice. Fifteen healthy onion bulb roots were used and subjected to 0%, 2%, 6%, 10%, and 14% concentrations of Bayluscide and distilled water. Excised root tips were prepared for slides, and cytological changes were examined under the microscope. The cells counted and observed were subjected to Analysis of Variance (ANOVA), Duncan Multiple Range Test, and Mitotic Index. As reflected in the result, there was a significant decrease in cells undergoing cell division as the treatment concentration increased. Cells at the interphase stage increased in number as the concentration increased during the prophase, metaphase, anaphase, and telophase showed a marked decrease in number. Cytological abnormalities noted were shrunken and a broken nucleus
University of Bohol Employees Work Engagement: Measuring Workplace Productivity
Get PDFTheories on work engagement posited that engaged employees are physically, cognitively, and emotionally driven to attain organizational goals. Thus, they produce high levels of workplace productivity. Workplace productivity indexes serve as a parameter that measures how satisfactorily employees are doing and what motivates them to achieve higher goals and higher levels of efficiency and effectiveness. This study aimed to determine the level of work engagement of the human capital of the university as measured by workplace productivity. A quantitative-descriptive method with the use of the Workplace Productivity Snapshot Tool was utilized in the conduct of the research. The data collected were analyzed and interpreted using simple percentages, weighted mean, and one-way Analysis of Variance. Results showed that the UB employees were highly productive in building leadership and management capability, organizing work, networking, and collaboration, and measuring what matters. However, they are moderately productive in creating productive workplace cultures, encouraging innovation, and the use of technology, and investing in people and skills. Workplace Productive Snapshot Tool yielded moderately productive as those needing continuing feedback, monitoring, and evaluation to keep up with individual and environmental challenges. Based on the salient findings, it is elemental to determine the learning and development needs. Such will enable the employee to improve performance and achieve higher workplace productivity continually
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
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
