    The 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

    Food traceability in the context of Karoo lamb : supply chain and consumer perspectives

    Dissertation (MConsumer Science)--University of Pretoria, 2012.‘Karoo lamb’ is a product with specific regional qualities that are based on, among other factors, the natural environment present in the region of origin. Together with the specific product qualities, regional image factors create a unique identity for a product, as is the case of ‘Karoo lamb’, in this way bringing about added value. Consumers will only consume food products that fulfil their specific requirements and have become more demanding about what they want. As food markets have become more globalised, consumers have become more concerned about the origin of the food they eat, with decreased confidence in the quality and safety of foods produced outside their local region or country. Traceability systems address these concerns, and the importance of establishing a link between a product, producer and place of production has therefore gained momentum as a trend. The overall goal of the research was to explore the role and contribution of traceability as a system relating to a product of origin, specifically ‘Karoo lamb’, and the influence it has on consumers’ decision-making processes when selecting and purchasing ‘Karoo lamb’. Consumer decision making is a complex and dynamic process that can be explained according to a consumer decision model that specifies its various stages. The research was conducted in three phases. During the first phase a quantitative research approach was followed to investigate and describe the audit processes that have been implemented by different retailers in South Africa regarding the traceability of lamb meat. In the second phase, focus group sessions, a recognised qualitative research technique, were conducted to identify the product attributes that were critical to consumers’ preferences and choices regarding the product, ‘Karoo lamb’. In the third phase the attributes, namely price, safety, quality, traceability and origin, were identified as significant factors influencing consumer choice and used in a conjoint questionnaire. A quantitative approach was followed in phase three and a questionnaire was used to measure the importance individual consumers attach to the different levels of the various product attributes. The utility values were based on the survey participants’ evaluation of the complete product. Price is often known to be one of the most important and determining factors in the consumer’s decision-making process. A higher price can sometimes symbolise better quality or safety of the product for the consumers. The results from the conjoint questionnaire have shown that price, as an extrinsic attribute, was found to be the most important factor in a consumer’s decision-making process at 30.4% when purchasing lamb. Safety at 23.1% was the second most important attribute after price. This is not surprising given the legacy of BSE and e-coli outbreaks that were given much publicity in the press. The third attribute affecting the purchasing decision was quality at 17.0%. The fourth attribute of traceability affected the purchasing decision at 15.7% and the importance of the fifth attribute, region of origin, was 13.8%. According to the participants, the origin attribute had the lowest rating of importance of all five attributes selected for the conjoint questionnaire. As the conjoint experiment was conducted electronically, the participants of the conjoint questionnaire were solicited with the assistance of a marketing research firm, Consulta Research (Pty) Ltd., based in Centurion in the Gauteng province of South Africa, and were part of the consumer panel of consenting survey participants for the company. In total 352 completed questionnaires were used in the data analysis. The buying and/or consuming of mutton or lamb were the only criteria that needed to be met for participation in the conjoint questionnaire. In conclusion it can be said that there is a lack of certification and guarantee in South Africa that the product that is marketed as ‘Karoo lamb’ truly originates from the Karoo, and consumers can easily be misled as to the true origin of the lamb being sold. Traceability can be an important tool to help to establish the authenticity of food products and to check that claims made by producers are true. AFRIKAANS : Karoo lamsvleis is ‘n streeksgebonde produk wat gebaseer is op die natuurlike omgewing in die gebied van oorsprong. Tesame met die spesifieke produk gebaseerde kwaliteite word ‘n unieke produk identiteit geskep deur die streeks faktore soos gesien met Karoo lam en hiermee bring dit toegevoegde waarde mee. Verbruikers sal slegs voedselprodukte aankoop en eet wat hul spesieke aanvraag benodigdhede vervul. Omdat voedselmarkte wêreldwyd meer en meer impak maak op verbruikers begin hulle konsentreer op die herkoms van produkte. Verbruikers het verminderde vertroue in die kwaliteit en veiligheid van produkte wat geproduseer word buite streeks- en landsgrense. Naspoorbaarheid sisteme spreek hierdie probleme aan en die belangrikheid om ‘n skakel tussen produk, produsent en plek van produksie te vind het veld gewen as tendens. Die primêre doel van hierdie navorsingsstudie was om die rol en bydrae van naspoorbaarheid as ‘n sisteem ten opsigte van produk oorsprong en spesifiek Karoo lamsvleis te ondersoek, asook die invloed daarvan op verbruiker besluitnemings tydens die keuse en aankoop van Karoo lamsvleis. Omrede die verbruikers besluitnemingsproses kompleks en dinamies is kan dit verduidelik word met ‘n verbruikers besluitnemings model wat die verskillende fases van die proses beskryf. Die studieprojek is uitgevoer in drie fases. Met die eerste fase is ‘n kwantitatiewe benadering gevolg om ondersoek in te stel en te beskryf hoe en watter ouditprosesse geïmplimenteer is deur groothandelaars ten opsigte van die naspeurbaarheid van lamsvleis in Suid Afrika. Tydens fase twee is fokus groep besprekings, ‘n kwalitatiewe navorsings tegniek, geloods om die produk kenmerke wat verbruikers besluitneming ten opsigte van die produk lamsvleis beïnvloed te bepaal. Die kenmerke prys, veiligheid, kwaliteit, naspeurbaarheid en oorsprong is geïdentifiseer en gebruik in fase drie, die voorkeurkeuse ontleding. ‘n Kwantitatiewe benadering is gevolg in fase drie om die belangrikheid te bepaal wat verbruikers heg aan die verskillende kenmerke en die vlakke van die onderskeie produk kenmerke. Prys is bekend as een van die mees belangrikste en invloedryke faktore in die verbruikers besluitnemings proses. ‘n Hoër prys simboliseer soms beter kwaliteit en veiligheid aan ‘n verbruiker. Die resultate van die voorkeurkeuse ontleding het getoon dat prys met 30.4% as ‘n uiterlike kenmerk, die belangrikste invloed het op verbruikers besluitneming. Veiligheid met 23.1% was die tweede belangrikste kenmerk na prys. Bogenoemde was nie ‘n verrassing nie aangesien die pers wêreldwyd al baie aandag gegee het aan die uitbreking van die e-coli epidemies. Kwaliteit was die derde belangrikste kenmerk wat verbruikers besluitneming bëinvloed het met 17.0%. Naspeurbaarheid as kenmerk het die besluitnemings proses bëinvloed met 15.7% en oorsprong in die vyfde plek met 13.8%. Daar is gevind dat oorsprong as kenmerk verbruikers se besluitneming die minste beïnvloed het. Die deelnemers aan die elektroniese voorkeurkeuse ontledingsopname is verkry vanaf die databasis van die bemarking navorsings maatskappy Consulta Research (Pty) Ltd, wat geleë is in Centurion, in die Gauteng provinsie van Suid Afrika. ‘n Totaal van 352 voltooide vraelyste is gebruik vir die data analise. Die aankoop en verbruik van lam en skaap vleis was die enigste kriterium wat gebruik is in die werwingsproses van die deelnemers. Samevattend kan genoem word dat daar ‘n gebrek bestaan in Suid Afrika in die sertifisering en waarborg van die produk Karoo lamsvleis wat bemark word as afkomstig van die Karoo. Sodoende kan verbruikers maklik mislei word oor die ware oorsprong van die produk. Naspeurbaarheid kan ‘n baie belangrike instrument wees om die geloofwaardigheid van voedsel te bepaal en te verseker dat die aannames ten opsigte van oorsprong wat produsente maak die waarheid weerspieël.

    Variations on the Author

    “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

    We 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

    We 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

    We 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 text
    In 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.
