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
Relationship between financial and real sectors: implications for stable economic development [evidence from Thailand]
No full textThesis (M. Econ.)--National Institute of Development Administration, 2018Economic real sector is essential for growth and development as its activities persuade progress of economic output. The sector generates better outcomes if it is accompanied with a healthier financial system; thus, advancement of financial sector is a means for the growth of real sector. This study reexamine the relationship between financial and real sectors of Thailand with the volatility analysis of GDP caused by development of financial market. The GARCH Model, Johansen-Juselius (1990) co-integration test, and vector error correction model (VECM) approach were employed on time series data over the first quarter of year 1993 until the second quarter of year 2017. Consistent with past studies, both the elements of capital market (i.e. bonds and stock markets) and the money market (i.e. credit to private sector by banks) bear a positive relationship to the GDP. Our results show that both markets help promoting economic growth. We can infer that differences in financial market composition and institutions do matter, as these three major sections – bond market, stock market, and banks– do not simultaneously develop and grow, but at a different level of their growth paths they complement each other. Our findings suggest that there exists interdependency between real sector and financial sector which in turn enlightens the effect of financial market development on the GDP growth.

In the race for sustainability and financial excellence: advancing firms' investment in knowledge assets and innovations
No full textThesis (Ph.D. (Business Administration))--National Institute of Development Administration, 2021This dissertation focuses on the firms’ investment management decisions regarding knowledge assets (intangible assets), innovation, sustainable investments, and other knowledge management practices through which firms generate both financial benefits and improved environmental outcomes. The previous title of this dissertation was ‘In the race for excellence: the role of knowledge assets and innovation’ (as appeared in the IRB document). The overall agenda is classified and decomposed into three major interrelated sections in an attempt to achieve the goals of this research. The main objective of the first study presented in Chapter 2 is the development and implementation of empirical models to examine the nonlinear impact of the key intangible assets and innovation formation through R&D on the firms’ financial performance of Asian countries. The difference between intangibles (knowledge-assets) and innovation and their combined impact on firm performance remains a puzzle since all types of knowledge assets are not of equal importance. Also, firms with higher spending on innovation can perform well. Integrating these two literature approaches, this study investigates how knowledge-assets and innovation impact firm performance by analyzing the sample of 2958 listed companies of Asian countries during 2015 – 2019. Using time fixed-effects panel regression with industry and country dummies, we observe that different sectors exhibit a strong heterogeneity in their investment level in knowledge assets and innovation. The study finds that more knowledge-assets negatively impact firm performance, but up to a point. The U-shaped relationship found suggests that learning and accumulating capabilities to exploit knowledge assets potential is essential to achieve higher firm value. We also find that firms' more spending on innovation positively impacts firm performance, but only up to a certain level. An inverted U-shaped relationship found suggests a balanced investment in innovation activities to attain improved firm performance. The main contribution of this study lies in identifying novel implications of these considerations, and offer novel evidence of their empirical relevance in four ways: (i) Difference between measures of internally generated and externally acquired knowledge-assets and measures of innovation; (ii) Theoretical and empirical justifications of U-shaped relationship between knowledge-intensity and firm performance; (iii) Support Schumpeterian theory of creative destruction by innovation; (iv) Theoretical and empirical explanations of inverted U-shaped relationship between innovation-intensity and firm performance.
Next, we have extended this model in our second study to capture the environmental impacts of the investments in innovation by employing a set of Environmental, Social, and Governance (ESG) indicators presented in Chapter 3. Recently, the level of climate change has substantially been rising; relatively not much is known on ‘how’ companies alter the association between their environmental performance and financial performance within the context of specific elements of innovation: conventional innovation and green innovation. Drawing upon the stakeholder theory and the natural resource-based view of the firm, this research uses firm-level Environmental, Social, and Governance (ESG) data of 462 companies across 7 Asian countries for the period 2015 – 2019, and employs time fixed-effects panel regression with country and industry dummies. We find that measures of innovation (i.e., conventional innovation and green innovation) are beneficial to the firm value. However, the positive effect of conventional innovation on the firm valuation builds at the expense of the environment since it poses a significant threat to environmental quality by positively contributing to carbon emissions. Whilst firms’ investments in green innovation are advantageous to either type of firm performance. Further analysis shows that firms that focus on environmental practices generate significant outcomes, e.g., improved financial performance, suggesting that firms should prioritize their green investments to enhance the innovation outcomes so as to achieve superior financial value and to attract potential environmentally proactive stakeholders. The contributions of this study to the stream of sustainable finance, innovation, and environmental management literature are fourfold. First, firm-level studies on environmental performance have been scant, mainly due to the unavailability of the data. Those who studied this phenomenon primarily relied upon the data collected through survey questionnaires on a specific group of firms within a particular sector and country. Since the growing Asian economies are being successful when evaluated basis on their swift growth, however less effective in preservation of environmental damage compared to other regions. Thus, we conduct this study in the Asian region by using firm-level ESG performance data, which allows us to uncover this existing challenge in cross-sectoral across different countries. Second, previous studies solely emphasize the broader aspects of R&D-augmented innovation and its outcomes on a specific performance measure, instead; in this study, we filled this gap by decomposing innovation into two types in which firms invest simultaneously and investigate their joint impact on various performance measures – financial and environmental. Third, our findings offer insights on the importance of complying with the environmental policies by investing in green innovation with an awareness that bringing an essential change in redesigning products for environmental sustainability via employing non-toxic materials in the production processes, using eco-packaging, eco-friendly labeling, lower energy consumption, and improved recycling and decomposition designs would enable firms to achieve productivity. Productivity improvement in the resources would allow these firms to obtain higher financial and environmental performance. The findings also contribute to the sustainable investment literature by signifying the investments in green innovation, since green innovation serves as the vital component through which firms could obtain market related benefits from their environmental investments, introducing systematically the steady chains of sustainable products and services with improved functionality and layout i.e., better recycling design, reduced energy consumption level, lowered exploitation of natural resources and materials, and improved product/service’s functionality with the better lifecycle. These eco-friendly products/services are shown to be advantageous to the companies in terms of gaining green products’ market share, formation of green branding, and the likelihood of setting premium prices. These benefits are specifically crucial to those firms who longing to be competitive in the green industry and to enhance their revenues and returns on investment.
Lastly, one of the limitations of the first study reported in Chapter 2 is that our investigation was limited to the analysis of knowledge assets which, though on a positive note, has been identified and codified in company statements – the objective data were accessible from public domains. However, we did not include intangible knowledge of certain other forms, such as managerial talent, practices, and tacit and explicit knowledge owned by employees which may meaningfully contribute to the firms’ entrepreneurial and innovation process. Against this backdrop, therefore, moving beyond the question of how innovation affects firms’ financial and environmental outcomes, to build theoretical insights and develop an approach that encourages us to estimate a firm-level model to quantify how firms’ innovative capabilities contribute to organizational learning (knowledge sharing) and corporate entrepreneurship. In particular, this study presented in Chapter 4 examines the role of organizational innovative capabilities on the relationship between knowledge sharing, corporate entrepreneurship, and firm performance. Specifically, this study uses the knowledge-based view (KBV) to develop a model that examines the mentioned relationship. Using survey data from 520 participants across 75 service sector companies in Thailand, measurement and structure models are tested through Structural Equation Modeling (SEM) to quantify the impact between constructs. The findings of this study show that knowledge sharing and corporate entrepreneurship positively affect organizational innovative capabilities and firm performance. A positive relationship is also found between knowledge sharing and corporate entrepreneurship. The mediating impact of organizational innovative capabilities strengthens the relationship between knowledge sharing and corporate entrepreneurship on firm performance. These findings contribute to the knowledge-based view, innovation management, and entrepreneurship literature by suggesting that to improve organizational learning and knowledge-based performance, commitment, and understanding of the employees in the entire organization is crucial. Knowledge sharing significantly contributes to developing innovative abilities because of its characteristics of providing firm-specific and socially complex advantages. The way a firm transforms and exploits its knowledge may ascertain its level of innovativeness, such as coming up with certain problem-solving procedures and new product development according to the rapid change in the market demand.
We believe that the findings of this research are instrumental to management, practitioners, academics, and policymakers in offering key insights on optimal investment strategies concerning knowledge assets and innovation. This research offers ways to advance innovation such that to achieve higher firm value and better environmental prospects. Finally, this research instigates the tools to effectively organize knowledge as knowledge sharing boosts entrepreneurial practices and contributes towards innovativeness across individuals, groups, units, or the entire organization
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
