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
Succession planning as a tool to minimise staff turnover rate : a case study of Nedbank Homeloans' KZN Operations.
Get PDFThesis (MBA)-University of KwaZulu-Natal, Westville, 2010.This study explores the reasons why succession planning is imperative in an organisation. The
study focuses on Nedbank Homeloans’ KZN Operations at the head office in central Durban and
includes the views of the office staff about the salient issues in regards to succession planning.
A comprehensive literature review provides a background to the study. A number of reasons for
the need for succession planning have been provided by various writers, and these constitute the
point of departure for the study. The broad themes that impact on the success of succession
planning are identified as being the need to retain talent, to develop skills, and to enhance the
benefits that can be derived from implementing succession planning in an organisation.
In relation to these themes, the main objectives of the study were the following: to determine
what benefits the organisation may achieve from implementing a succession plan; the significant
impacts of not having a strategic succession plan; what an organisation can do to retain talented
and competent employees; the role an organisation can play in sustaining skilled and talented
people; and if the implementation of succession planning can support the career paths of
employees not just up a specialised ladder but across a continuum of professional competence.
The fieldwork was exploratory in nature, with a questionnaire being administered to seventyseven
home-loan staff across the different levels of function. The Statistical Package for Social
Sciences (SPSS) was used to analyse the data. Various statistical techniques such as Cronbach’s
Alpha were applied to test reliability.An in-depth analysis of the results of the questionnaire was performed. The results of the study were evaluated and various recommendations are made. An implementation plan is provided to aid in the implementation process
A study of vegetation change along the North Coast of KwaZulu-Natal from the Umgeni River to the Tugela River.
Get PDFThesis (M.Sc.)-University of Natal, Durban, 2000.The vegetation along the north coast of KwaZulu-Natal has long been considered to have originally consisted of forest, scrub forest and savanna. The classical view is that in the
last 600 years the early Africans and European farmers were responsible for the removal of forest and scrub forest along the coast. This view was not based on direct evidence but on the theory that the eastern part of the country has a climate "suitable" for forest and scrub forest. The present 'false' grasslands were thus thought to have developed through anthropogenic influences. All of this has its basis in the paradigm of ecological succession and the presence of a "climatic climax". This traditional view has been contested recently, based on archaeological, historical, biogeographical and ecological evidence that has become available since the 1950's. It is suggested that South Africa's grass lands have been in existence for the last two thousand years but probably for more than ten thousand years. This study aims to investigate this controversy in greater detail, using evidence from archaeological records, travellers records, transcripts, historical reviews, and diarised records. The locations of archaeological sites within the study area were determined and mapped out, followed by an analysis and interpretation of the data with reference to vegetation
change. Archaeological evidence included shell middens, evidence of iron working and pottery remains. The activities of the early humans included iron smelting, agriculture
and stock farming. Their activities required the selective use of vegetation for specific purposes, and vegetation was cleared for homesteads and villages. However, the density of people within the study area was low, and there was limited technological development, such that extensive clearing by relatively few people is unlikely. Furthermore, sites are concentrated along the coastline, with fewer sites away from the coast, suggesting that impacts would have been greatest along the coastline. However, this is where forests presently occur. Overall, the evidence suggests that the natural vegetation on the north coast was not modified drastically by precolonial settlers. Historical accounts of early travellers and settlers indicate a strip of forest along the coastline and a grassland/woodland mosaic away from the coast. Records of mammals suggest a fauna typical of savannas and not forest. With settlement over time, the major activity that impacted on the north coast vegetation, was agriculture. Sugar cane plantations contributed considerably to the clearing of vegetation that seems to have consisted primarily of open grasslands with patches of trees. Colonial settlement of this area resulted in various activities that required the large-scale removal of natural
vegetation. It is important to know the human disturbance history of an area as this helps to assess the extent of change and to design appropriate management strategies for conservation of plant resources. The belief that the early vegetation of the north coast was forest has placed great emphasis on the conservation of forests along this coastal area. Based on this study, it seems that this vegetation type should not be the focus of conservation
efforts, but that coastal grasslands with scattered bush clumps should be given much greater emphasis. Grasslands were more widespread in the region prior to European
settlement, and based on this, conservationists should place greater emphasis on preserving this habitat
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
