Climate change and slow economic growth are triggering an increase in pressure on global WEF resources. These present an increase in levels of trade-offs and conflicts among the three resources. The implementation of the WEF nexus can improve resource security and promote sustainable development. However, its widespread adoption has been limited due to the absence of concrete strategies for its practical application. This study assessed the status of WEF nexus smart technologies, innovation and practices in Luvuvhu and Nzhelele River Catchments Areas, Limpopo Province, South Africa. Subsequently, face-to-face surveys were undertaken from 9 July to 30 November 2022 for individual households and focus group discussions (FGD) were conducted within communities under the Luvuvhu River Catchment Areas (Sambandou, Malavuwe and Tshakhuma); and Nzhelele River Catchment Areas (Siloam, Phadzima and Khalavha). A random sampling technique was utilized to select 93 households from a total of 180 targeted households. Key Informant Interviews (KII) were conducted with representatives from the local Department of Water and Sanitation, Eskom, the local Department of Agriculture and Rural Development, as well as local radio stations. During these interviews, data was collected through interview-administered questionnaires. The data obtained from the questionnaires was analyzed using IBM SPSS Statistics version 29, which facilitated the generation of response frequencies. Additionally, the ArcGIS Inverse Distance Weighting (IDW) spatial interpolation method was employed for spatial analysis. The results indicated that the sustainability of the water-energy-food (WEF) nexus depends on the resilience of each resource individually as well as within their respective sectors. The use of water and food smart innovations and practices was found to be slightly higher in the Nzhelele River Catchments Areas than it is in the Luvuvhu River Catchment Areas, with 55.9% (n= 55) and 38.7% (n= 36) of the respondents within the Nzhelele area and 47.3% (n= 44) and 31.2% (n= 29) in the Luvuvhu area using water and food smart innovations and practices, respectively. Moreover, the use of energy innovations and practices was found to be slightly lower in the Nzhelele area s (53.8%; n= 50) than it is in the Luvuvhu areas (59.1%; n= 55). However, most of the respondents in both study areas did not understand how WEF nexus works, whereas some practiced it based on the little knowledge they got from schools, workplaces and the internet. Results from assessing the influence of hydrology on the use of WEF Nexus smart innovations, technologies and practices showed that hydrology is a foundational element in the WEF Nexus as hydrological factors such as water quality, temperature variability and annual rainfall are very crucial in WEF Nexus, influencing the use of smart innovations and practices that could in turn improve the well-being of residents, the productivity of local agricultural and food systems while enhancing the sustainable management of water, energy, and food resources. The study results show that the use of water, energy and food in areas around Luvuvhu River Catchment and Nzhelele River Catchment are significantly impacted by hydrology. It was also noted that a significant percentage (90%) of the respondents reported that they depend on agriculture for survival, which is highly affected by hydrological conditions.
Knowledge about the WEF nexus needs to be transferred to people in rural areas through awareness and education. The results of this study can serve as a useful reference for developing regions to improve management of resources, facilitate sustainable development, and fill the existing knowledge gaps towards understanding how promising the WEF nexus innovations and practices are, and how these can be realized at the local community and household levels. Thus, potentially reducing the shortage of WEF resources.Water Research Commission (WRC
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
