Intellectual capital and firm performance in the global agribusiness industry: The moderating role of human capital
No full textPurpose
The main objective of this paper is to investigate the relationship between intellectual capital (IC), categorized in terms of four sub-constructs – namely human, relation, innovation and process capital – and business performance in the agribusiness industry.
Design/methodology/approach
Based on a sample of international agribusiness companies observed over a five-year period, this paper uses correlation and multiple regression analysis to test for the existence of a positive relationship between each IC component and conventional business performance metrics.
Findings
The empirical results support the hypotheses that relation and process capital have a positive impact on corporate performance. Counter to our expectations, innovation capital by itself is negatively asssociated with performance. Results also failed to confirm the hypothesis that human capital directly and positively affects performance. However human capital positively moderates the relation between innovation capital and performance, which suggests that firms that heavily invest in human capital are better placed to gain returns from their R&D investments.
Originality/value
This study expands the existing research on the link between intellectual capital and performance by adding fresh evidence from a highly knowledge-intensive sector which has been under-researched thus far. It may also contribute to the specific literature on R&D and performance as it uncovers that the value-generating effect associated with R&D investments is contingent on the levels of human capital
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
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
Università di Roma Tor Vergata
No full textIl contributo s'inserisce nel più ampio progetto di ricerca del GSA Aidea su "Creazione di imprese e spirito imprenditoriale" e indaga, con specifico riferimento al campione studentesco dell'Università di Roma Tor Vergata, la propensione imprenditoriale e i fattori a livello personale, familiare e di contesto che possono guidare la scelta di diventare imprenditori. Il taglio iniziale dell'analisi empirica è di tipo descrittivo, mentre nella seconda parte del lavoro viene svolta un'analisi di correlazione sulle variabili che influenzano maggiormente le intenzioni imprenditoriali degli studenti. I risultati mostrano che la maggior parte degli intervistati esprime una propensione imprenditoriale medio-alta, a fronte di una forte correlazione con il ruolo esercitato dalla famiglia e più in generale dai gruppi sociali di riferimento nell'approvare tale scelta. Motivazioni personali, esperienze lavorative coerenti e soft-skill potrebbero contribuire a rafforzare la maturazione della decisione, mentre il contesto socio-culturale di riferimento sembra non contribuire all'intenzione dei giovani universitari romani a volere avviare un'impresa. Il lavoro s'inserisce negli studi sull'imprenditorialità in una prospettiva micro, centrata sull'individuo, e contribuisce alla scarna letteratura italiana sul tema delle intenzioni imprenditoriali, confermando la presenza di indizi di imprenditorialità latente in giovani universitari con specifiche caratteristiche. Limitazioni derivano dalla metodologia analizzata per l'analisi delle relazioni, mentre ulteriori approfondimenti sono rimandati a ricerche future
