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
Corruption in Customs: External Causes, Consequences and Cures
No full textCustoms carry out a wide range of vitally important fiscal, economic and social functions throughout the world. Corruption which is defined as the abuse of public power for private benefit is an important problem in customs. Corruption in customs seriously hinders the flow of international trade, undermines the legitimacy of the customs administration, creates an uncompetitive business climate, increases transaction costs for public and private sectors, reduces foreign investments, leads to serious revenue loss, ruins national security and community protection. The purpose of this study is to examine the external causes, consequences, and anti-corruption measures in customs
On the symmetric and asymmetric Granger causal relationship between oil prices and financial stress in six major European countries
Get PDFPurposeThis study aims to examine whether there is a symmetric and asymmetric causality relationship between oil prices and financial stress.Design/methodology/approachThe study applies Gregory-Hansen's (1996) cointegration and Nazlioglu et al.'s (2016) Fourier-Toda-Yamamoto (F-TY) causality approaches to monthly data from six European core economies: Germany, the United Kingdom, France, Italy, The Netherlands and Spain, covering the period 1987:M05-2023:M08.FindingsExcept for Spain, the authors find a symmetric causality relationship between oil prices and financial stress across the sampled countries in at least one or both directions. Regarding asymmetric causality, the results reveal a feedback causality relationship between positive shocks in financial stress and negative oil price shocks in Germany and France; a unidirectional causality from positive financial stress shocks (heightened financial stress) to negative oil price shocks (sudden price decreases) in Italy and Spain; a one-way causality from negative financial stress shocks to positive oil price shocks (sudden price increases) in the UK; and no causality in The Netherlands.Originality/valueThis study adds to the body of knowledge in three ways. First, it enriches the limited empirical research on the asymmetric causality relationship between financial stress and oil price shocks. Second, it uses a newly developed Fourier-Toda-Yamamoto (F-TY) causality approach that yields reliable results even for structural breaks. Finally, given the importance of oil as a vital input for six European core economies that import oil, identifying the link with financial stress can provide policymakers and scholars with fresh policy insights and research opportunities
Remittances and financial development in Bangladesh: substitutes or complements?
Get PDFUsing the ARDL model and recently developed financial development index, we test whether there is a non-linear relationship between financial development and remittances over the period 1980-2015 in Bangladesh. The results suggest that there is a non-linear U-shaped relationship between financial development and remittances, supporting the complementarity hypothesis both in the long and short run. The evidence provided is robust to alternative variables that potentially influence financial development. Given the complementarity relationship between the two variables, policymakers in Bangladesh should pursue policies and reforms aimed at promoting the inflow of remittances to Bangladesh
Do Remittances Lead to Financial Instability? Evidence from Selected Asia-Pacific Countries
Get PDFThe Asia-Pacific region is among the top recipients of international remittances globaly. This study examines the impact of remittances on financial instability and investigates whether the causal relationship between remittances and financial instability is symmetric or asymmetric in selected remittance-dependent Asia-Pacific countries: Pakistan, the Philippines, and Sri Lanka. Using the frequency domain causality approach and monthly data (Pakistan: 2005m01-2023m08; the Philippines: 1998m10-2023m08; Sri Lanka: 2015m01-2022m12), the results reveal both symmetric and asymmetric unidirectional causality from remittances to financial instability in Sri Lanka. In Pakistan, symmetric and asymmetric causality is observed from financial instability to remittances. No significant symmetric or asymmetric causal relationship is found in the Philippines. These findings suggest that recognizing asymmetric effects is essential for designing targeted policy responses in remittance-dependent economies. In particular, strengthening formal remittance channels, enhancing financial sector resilience, and using foreign exchange interventions in crisis-prone contexts like Sri Lanka can help mitigate remittance-induced instability
Do industrialization, democracy, and financial openness promote financial development? Evidence from Turkey
No full textThis study aims to unweil the determinants of financial development, particularly the impact of industrialization, democracy, and financial openness on financial development in Turkey over the 1975-2015 period, using a bounds testing approach. It is found that (i) financial development and its main determinants are co-integrated; (ii) democracy is positively associated with financial development, whereas financial openness is associated with lower financial development; and (iii) industrialization is not a significant determinant of financial development in Turkey. Based on the obtained results, some recommendations are also provided
Frequency-domain and time-varying asymmetric Granger causality between real effective exchange rates and remittances in Mexico
No full textThe sheer size of remittances has fostered an interest in investigating the consequences of these flows, particularly in remittance-dependent economies. This study relies on monthly data from 1995M01 to 2021M05 and uses both frequency-domain and time-varying causality approaches to investigate the asymmetric causality relationships between real effective exchange rates and remittances in Mexico. Two key results are obtained. First, according to the frequency domain causality test results, positive shocks to remittances lead to appreciation in the Mexican peso in the medium- and long-run cycles, but negative shocks to remittances do not lead to depreciation in the Mexican peso, thus suggesting non-asymmetry. Second, the results of time-varying causality based on heterogeneous errors support asymmetric behavior between real effective exchange rates and remittances, underscoring the importance of allowing asymmetries when investigating the causal relationship
