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
Corporate governance of banks in Vietnam and their roles on banks’ risk-taking and efficiency : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Banking Studies at Massey University, Manawatu Campus, New Zealand
Full text linkThis thesis comprises three essays that investigate the effectiveness of corporate governance mechanisms associated with recent Vietnamese banking reform on Vietnamese banks’ risk-taking and efficiency. The thesis uses a hand-collected dataset on accounting and corporate governance data from annual statements published by commercial banks during the 2006-2016 period.
The first essay examines the role of foreign directors on bank risk-taking, using data from 32 commercial banks in Vietnam in the 2006-2016 period. Our findings suggest foreign directors increased bank risk-taking after 2011. The relationship is robust after taking account of potential endogeneity problems and different measures of bank risk-taking. The explanation is that foreign directors are motivated to encourage management to increase risk-taking to earn short-term returns when there is uncertainty in macroeconomic conditions. Other characteristics such as female directors, family related directors, and board size on risk-taking are also discussed. There is no evidence showing that foreign directors are more or less risk-averse in listed banks vs unlisted banks or in state-owned banks vs private banks.
The second essay investigates the impact of female directors on boards on bank efficiency, using data from 32 commercial banks, covering the 2006-2016 period. The relationship is estimated by employing one-stage stochastic frontier analysis, using the Battese and Coelli (1995) (BC95) approach. The two-stage distributional free approach proposed by Cornwell, Schmidt, and Sickles (1990) (CS90) is employed as a robustness check. The result shows a robust relationship between female directors and cost-efficiency. This suggests that female directors are associated with a decrease in cost efficiency. A possible explanation is that female directors are less experienced in management than male directors and have less access to environmental resources that benefit firms.
The third essay examines the impact of mergers and acquisitions (M&As) on bank efficiency, using a balanced panel dataset from 22 commercial banks over the 2008-2016 period. The study employs a two-stage DEA window analysis. Our findings suggest that there is no significant relationship between M&As and bank efficiency, which is not surprising given the small number of M&A events so far. However, there is evidence that Vietnamese banks experienced less improvement in efficiency after M&As. A possible explanation for this is that the M&As might not be not driven by profit-maximization, but by the government encouragement to rescue weak banks. Also, the combined entities need to spend additional resources on resolving the bad debts transferred from the weak, targeted banks
Factors influencing bank deposits : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy (PhD) in Banking at Massey University, Palmerston North, New Zealand
Full text linkThis thesis comprises three essays that investigate the effects of human capital, financial markets, and the banking system development on bank deposits, deposit funding, retail, and time deposits proportions. The first two essays are country level studies, whereas the third is at bank level. The data related to first essay has been obtained from the World Bank and the World Health Organisation (WHO). For the second and third essays, bank level data is from Bankscope and macroeconomic variables data are from the World Bank.
The first essay investigates the effects of human capital development on bank deposits, employing 2SLS method in a cross-country setup. Human capital development includes the development of the healthcare system and education level. I use two dependent variables: deposits to GDP ratio and value of total deposits. Results show a positive relationship between human capital development and bank deposits. However, the impact of healthcare system on total deposits is higher than the bank deposits to GDP ratio, suggesting that an improvement in the healthcare system increases households’ income and a proportion of that increased income goes into the banking system. The impact of education is higher in high financially included countries than in less financially included countries.
The second essay examines the effects of financial markets development on bank deposits, using instrumental variables methods. Empirical results suggest that investors in developed and developing economies use financial markets differently. In highly financially integrated economies, the financial markets and banking system complement each other, whereas in fragmented markets they compete.
The third essay explores the effects of competition on bank deposit funding and composition. Interest cost has been used to measure deposit competition and the Herfindahl- Hirschman Index (HHI3) at deposits and loans levels to measure market structure. The results show that increased deposit competition encourages banks to increase the proportion of less costly funds, causing a reduction in deposit funding. In contrast, high interest rates attract retail depositors, especially for time deposits, thereby increasing the proportion of retail deposits. However, this finding varies according to the financial development level of the countries. Market concentration shows negative effects on bank deposit funding and composition
Customer behaviours and online banking in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Banking at Massey University, Manawatū campus, New Zealand
Full text linkRecent technological developments in the financial sector have led to renewed interest in studying bank-customer relationships. The present study examined the effects of six demographic characteristics (i.e. age, gender, household income, education, employment and marital status) on the use of online banking in New Zealand. Three research questions were addressed: How do different personal characteristics affect customers’ use of online banking? How do these characteristics interact with each other in affecting customers’ use of online banking? and How do different characteristics affect the key factors that form users’ perceptions of online banking usefulness?
We used a three-pronged data collection methodology including four focus group discussions an online survey and twenty-six qualitative interviews. The survey was taken by 758 respondents and the completion rate was 76%. A range of descriptive and empirical analytics were used and strong effects of customer demographics on online banking use were found. The explanatory power of the six characteristics was examined using stepwise backward regression modelling while ANOVA tests confirmed interactive effects between combinations of characteristics. Through Principal component analysis, we identified a subset of four key constructs to represent the major areas of themes where customer perceptions differ regarding the use of online banking. Ordinal logit regression determined how perceptions differ on the basis of the differences in demographics.
Academically, this research examines the predictive utility of demographic characteristics in explaining New Zealanders’ use of online banking technologies from both banking and marketing perspectives. Expanding on demographic relationships as proxies for deeper drivers of behaviours, this study offers practical lessons for effective segmentation and engagement strategies. It reminds banks that understanding customer personas is the first step to effective targeting or personalization. This is critical in developing customer-centric banking in New Zealand and other regions
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
