No full textM.Sc. (Zoology)Suidwes-Afrika is. tn land van kontraste. Dit is tn dorre gebied waar water die paspoort is tot lewe. Die jaarlikse reenval is betrekIik laag (280mm, Dept. Waterwese. 1972) sodatdie natuurlike dreineringsisteme vir die grootste gedeelte van die jaar bree sandslote is. Tydens die kort reenseisoen verander dit egter in bruisende watermassas, wat afloop om uiteindelik in die see, moerasse .of die sand van die Kalahari te verdwyn. Die bou van groot opgaardamme soos die Hardap-, Naute- en Von Bachdam het hierdie watermassas vir mens en dier opgegaar. Die vraag ontstaan egter of water, wat vir mens, dier en op besproeiingslande beskikbaar gestel is, ten volle benut word
Impact of one-day adventure-based experiential learning (AEL) programme on life effectiveness skills of adult learners
No full textDespite positive claims made by advocates of adventure-based experiential learning (AEL), sceptics could be concerned that such claims are overzealous. Due to the expansion of AEL programmes into management training in business schools and the corporate world, ongoing empirical investigations relating to the efficacy of AEL in the workplace is necessary. The aim of this study was to determine the developmental impact of a one-day AEL programme on the life effectiveness skills of adult learners in a business school. A one-day ropes course programme was offered to 140 adult learners from the business school. The Life Effectiveness Questionnaire, Version H (LEQ-H), served as measurement tool and it was administered as a pre- and post-test measurement. The overall post-test scores of the experimental group (n=140) were significantly higher (p=0.0001) than the post-test scores of the control group (n=126). The post-test scores of four dimensions differed significantly (p<0.05) from the post-test scores of the control group. The findings indicate the potential efficacy of an AEL course for the development of life effectiveness skills in adult learners. It demonstrates the necessity of ongoing research directed at principles underlying the application of particular methodologies and other programmatic factors to maximise efficacy.Key words: Adventure; Experiential learning; Life effectiveness; Adult learners
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
The Impact of a one-day adventure-based experiential lernaing programme on the communication competence of adult learners at a business school
Full text linkIn today’s dynamic business environment, every avenue that can contribute to fostering business performance has to be embraced. Interest in the contribution of communication to organisational effectiveness and performance has increased considerably in the last few decades. Despite positive claims made by advocates of adventure-based experiential learning programmes (AEL), the expansion of AEL into business schools and the corporate world necessitates ongoing empirical investigations. The aim of the study was to determine the developmental impact of a one-day programme on the communication competence of adult learners at a business school. The Communicative Adaptability Scale was administered as pre- and post-test measurement to adult learners with a permanent work appointment who enrolled for a qualification in management leadership in a business school at a university in South Africa. The overall post-test scores of the experimental group (n=140) were significantly higher (p=0.0001) than the post-test scores of the control group (n=126). The post-test scores of five dimensions differed significantly (p<0.05) from the post-test scores of the control group. The findings indicate the potential efficacy of an AEL course for the development of communication competence in adult learners. Ongoing research directed at principles underlying the application of particular methodologies and other programmatic factors to maximise efficacy in reaching the desired outcomes of the interventions, are required
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
