State-owned Enterprises in the global market: Varieties of government control and internationalization strategies
No full textWe study the internationalization of State-owned Enterprises (SOEs) in the 21st century and its underlying
firm-level and country-level drivers. Using a global database of more than 110,000 M&A (10% having a
state-owned acquirer), we empirically investigate differences between private enterprises, traditional SOEs and
contemporary reformed SOEs. We show that the intensity of government control is associated with diverging
targeting strategies and internationalization patterns. Compared to traditional SOEs, reformed SOEs are more
outward-oriented, tend to purchase better performing targets, concentrate their investments towards less risky
countries that are geographically and culturally closer, with better institutional quality and a more central
position in the trade network. Our findings are consistent with the view that reformed SOEs are increasingly
adopting market-oriented strategies thus diverging from traditional SOEs (and converging towards the private
model) in their objective functions
Boat traffic in the Lampedusa waters (Strait of Sicily, Mediterranean Sea) and its relationship to common bottlenose dolphin Tursiops truncatus distribution
No full textThe volume of boat traffic and its potential connection to the coastal distribution of the common bottlenose dolphin (Tursiops
truncatus) was evaluated off Lampedusa Island (Strait of Sicily). From July to September 2006 daily surveys were carried out at eight sites
along the coast, three times a day, to assess the number, type, and size of boats moving, fishing, or stationed in Lampedusa waters. The study
area was divided into four geographic areas: northwest, northeast, southwest, and southeast. Data were analyzed to determine the difference in
the number of boats among the areas, sampling months, and times of day. The presence of dolphins was monitored by standardized land-based
observations. Dolphins (n = 139) from 38 sightings were observed throughout the study period (90 days). In order to compare the presence of
dolphins among areas, a relative abundance index was used: A-EH (number of sighted specimens per effort hour). Common bottlenose
dolphins appeared to be broadly distributed around Lampedusa, although this study highlighted a possible overlap between their habitat, boat
traffic, and fishery, especially in the southwest
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
Investment in Renewables under Uncertainty : Fitting a Feed-in Scheme into ETS
No full textWe analyze incentives to invest in renewable energy technologies induced by the overlap of two types of policies: feed-in schemes and carbon mitigation instruments. We find that results differ markedly depending on the specific types of policies in place, reflecting different impacts of uncertainty. As a result, the recent reform to the EU-ETS system that has established the Market Stability Reserve (MSR), effective in 2019, requires to appropriately fine-tune the direct RES-E support schemes. We show that this may involve moving away from feed-in tariffs towards feed-in premia. Our results suggest that the schemes currently adopted in Germany and in Italy, broadly based on feed-in premia for large generators and on feed-in tariffs for the small ones, could well fit also the post-MSR EU carbon mitigation policy. To the contrary, other countries (e.g. France and the U.K.) may have to modify their support schemes as the MSR will become operational
