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
Online reputation management at a HEI : social media managers’ views
Full text linkM.A. (Strategic Communication)Abstract: The role of social media managers in Higher Education Institutions (HEI) managing online reputation management has become a multifaceted and challenging profession in today’s contemporary world; this is due to technological advancements, virtual communities where information is easily created, accessible and shared openly and freely among these communities thus affecting an organisation’s reputation. The purpose of this study was to investigate the perceptions of the University of Johannesburg’s (UJ’s) social media managers in faculties regarding their role in managing the online reputation of a HEI. The study further intended to explore if social media managers have clearly defined roles that are guided by the UJ social media policy and appropriate training to assist in executing their roles effectively and strategically when a crisis occurs. The literature discusses three key concepts namely online reputation management, social media and strategic communication. The population of this study was specialist staff members at the University of Johannesburg (UJ), appointed with the task of managing the social media of the university and/or faculties. This research made use of a census to investigate their perceptions regarding their role as social media managers. The census consisted of two staff members from the College of Business and Economics, seven marketing executives from UJ Faculties (who manage social media platforms such as Facebook and Twitter) and the UJ social media manager. Data was collected by means of an interview schedule using semi-structured open-ended questions during face-to-face interviews. The semi-structured open-ended questions included the use of probes to elicit detailed information. All interviews were recorded and transcribed for thematic analysis by identifying common themes and differences. The research findings showed that although social media managers in faculties and departments are aware of their roles and responsibilities, a crises plan needed to be made available to all social media managers in faculties and departments of a HEI, should a crisis occur. The researcher recommends that social training should be compulsory to all faculty and department social media managers and that the social media policy needs to be simplified and shortened
Value creation in the 4IR: Millennials and Digital Multisided Platforms (MSPs)
Full text linkValue creation in the 4IR is customer-centric, interactive and hyper-personalised. Real-time consumer brand experiences, interactions and relations can be transformed into quantifiable data that can be monitored and tracked (‘datafication’). This study theorises that platform ecosystems, including millennials, converge on digital multisided platforms (MSPs), which are sociotechnical constructs that foment and generate significant value for platform owners and users. As value creation has risen as a digital economy business imperative, and a subject for academic research, the importance of millennials to brands warrants further investigation. This study aims to show how the interplay of social relations between millennials and brands, along with technology, are used to create value from the millennials’ perspective. To this end, it uses a consumer-dominant logic to explain and predict novel connections between key value creation constructs by millennial prosumers, including sole-creation, co-creation, collaboration, value destruction, value depreciation and value co-destruction. It presents three propositions that reimagine fit-for-purpose brands as interoperable constructs which exhibit complementarity, as well as the social dynamics of millennial interaction on digital MSPs. Findings indicate a cyclical value-interdependent relational system between millennials and brands, where millennial interaction leads to the creation or destruction of value. It also demonstrates how brands and platform owners can collaborate with millennials as an important and technologically savvy generation to co-create, capture and communicate value on digital MSPs
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 role of South African strategic communication practitioners as a 'moral compass' of an organisation during ethical crisis communication
Full text linkAbstract: As technology accelerates the Fourth Industrial Revolution, several aspects of ethics in a crisis have changed. It has become increasingly difficult for organisations to hide from ethical issues because of the advent of technology playing two key roles: amplifying the organisation's communication and compelling organisations to be transparent during crisis communication. These roles could expose the organisation's unethical behaviour...M.A. (Strategic Communication
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
University of Johannesburg millenials' communication of brand perception on facebook : implications for reputation management
Full text linkAbstract: The digital platform and Web 2.0 technology has removed old communication asymmetries and given rise to an empowered vocal emerging market Millennial. Millennial consumers cannot be ignored by brands from a size and monetary value perspective. Alongside the growth and brand sustainability potentials presented by Millennials comes the risk generated by their apathetic attitudes towards brand communication. The Millenriials' affinity for consumer-generated content that expresses approval or disapproval about brands on Facebook, has resulted in the emergence of new intermediaries, influencers as well as brand risk. The research undertaken sought to investigate Millennials' communication of brand perceptions on Facebook in order to ascertain whether such communication generate reputational risks for brands that are relevant to them and develop possible guidelines for the mitigation of such reputational risks. After two rounds of exploratory factor analysis, and reliability tests, a valid and reliable measure of Millennial brand perceptions on Facebook was developed explaining 62.81% of total variance and representing the key underlying conceptual dimensions. The instrument consisted of a series of filter questions, Likert response scales, two open ended questions, dichotomous questions, and nominal and ratio measurement questions. The questionnaire was selfadministered to a select group of 500 Millennial Facebook users between the ages of 18 to 24 at the University of Johannesburg. The results revealed that the brand perceptions communicated by 18 to 24 year old Millennials on Facebook brand communities are influenced by the inter-relations and intra-relations of the dimensions of Millennial Expressive Content, Millennial Expectancy, Millennial Influencers and Millennial Reaction. Within these dimensions the concepts of Millennial electronic word of mouth (MeWOM) and Millennial word of mouth (MWOM) emerged as descriptors of the brand perceptions communicated online and offline about brands. The results indicate Responsive Accountability as the most important subdimension to Millennials. Therefore it is a significant risk generator and opportunity for brands. This concept Millennial expectation, goes beyond the triple bottom line to include access to information and full disclosure about brands' activities. Post hoc tests indicated a difference between the brand perceptions of Average and Above Average/Affluent Millennials on Facebook. Results highlight the inter-relationship of the Facebook brand community with the broader digital sphere and offline world. The interplay between these dimensions represents the nexus between opportunity and risk for brands.M.Com. (Marketing Communication
