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
Re-examining the stability of money multiplier for the US: the nonlinear ARDL model
Full text linkThe rising uncertainties in the economy and the entwined global financial markets can easily cause nonlinear (asymmetric) behaviors among economic actors. Accordingly, this study re-considers the stability of the money multiplier from a different methodological perspective from that of prior studies, which assumed a linear relationship between money supply and monetary base. To this aim, the nonlinear ARDL model is applied for the US for the 2000M1-2018M9 period. Empirical findings of the nonlinear model indicate that only increases in positive monetary base shocks have a proportional relation with money supply. Additionally, the nonlinear ARDL detects proportional relationships between money supply and monetary base lower degree than the linear model
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
The Reasons and Economic and Political Consequences of Arab Spring
Full text linkMENA has always attracted great powers due to its central location, bearing crucial
waterways as well as housing divine places of three major religions (Islam,
Christianity and Judaism). MENA region possesses 54% of world oil and natural
gas resources. Natural gas is transferred from North African countries like Libya
and Algeria to Europe through pipelines and ships
Impacts of trade policy uncertainties on US-China bilateral trade
No full textThe escalating Sino-US trade war has led to a global economic contraction and increased trade policy uncertainties. This study examines the impacts of the US and China’s Trade Policy Uncertainties (TPU Indexes) on these countries’ Bilateral Trade Balances (BTBs). Empirical findings reveal that both increases and decreases in the TPU Indexes of both the US and China significantly affect their respective BTBs. Furthermore, it can be concluded that China’s trade policy or Chinese exporters-importers react to China’s trade policy uncertainty within China more than the US trade policy or US exporters-importers to US trade policy uncertainty within the USA. Another important conclusion is that China’s trade policy or exporters-importers react more to their own trade policy uncertainty than the US’s trade policy uncertainty within China. The policy implications generated from the empirical findings of this study for policymakers in both countries are presented in the paper’s final section
Do different socio-economic-demographic factors matter in COVID-19 related stay-at-home-tendencies across the US States?
Full text linkThis study investigates the potential impacts of different socio-economic-demographic (henceforth, SED) factors in COVID-19-related stay-at-home-tendencies (henceforth, COVID-19-SAHTs) in the US. This requires a state-level investigation rather than a country-level since the US states exhibit large SED differences from one another. To this aim, the K-Means Cluster analysis and the panel autoregressive distributed lag models are applied. The main empirical finding indicates that different SED factors in different US states matter in COVID-19-SAHTs. Additionally, people in the states which have more equal income distribution, higher rate of basic literacy, and less population density stay at their homes more during the COVID-19 pandemic. These findings may provide some vital pre-information to the state policymakers about how much the people from different SED statuses will tend to comply with future COVID-19 state restrictions such as stay-at-home orders and others. Until the scientists create a proven vaccine for the coronavirus, states will most likely continue to issue some COVID-19 restrictions to reduce the spread of this pandemic
Demand for Money in Greece After Euro Area and Policy Uncertainties
No full textThis study examines the asymmetric effects of uncertainties in monetary policy on the demand for money in Greece. In doing so, it introduces and uses the monetary policy uncertainty (MPU) index, which can probably be a very appropriate and robust explanatory variable in demand-for-money models. Therefore, this study with this index differs from previous empirical studies that use conventional uncertainty-based independent variables. Empirical findings of both models indicate that changes in the MPU index have significant effects on Greek money demand. Additionally, compendious inferences of the nonlinear model for the Greek people’s financial preferences are as follow as: (i): Greek people invest more in alternative financial instruments and/or spend their money rather than hold (demand) it when the MPU index increases, (ii): Greek people’s money demand in both increases and decreases in the MPU index is predominantly determined by longer-term bond rate changes
The Reasons and Economic and Political Consequences of Arab Spring
No full textWOS: 000216711400003A great many states have economic and polit ical interests in the Middle East and North Africa (MENA) region. This area has suffered from instabilit ies, autocratic regimes, economic hardships and radical movements as well as rich natural resources. In this study, the reasons and political and economic consequences of Arab Spring were studied. As far as we are concerned, this study is supposed to contribute to the related literature at a time when the democratic government was toppled with a coup d'etat in Egypt and ongoing civil war in Syria
