Projections of Electricity Demand in European Cities Using Downscaled Population Scenarios
No full textThis work projects future residential electricity demand derived from cities and municipalities’ population and residential land-use projections. Starting from national-level energy intensity data, we derived statistically downscaled residential electricity consumption with the aim to disaggregate residential electricity at the local administrative unit level for all EU member states in the year 2050. The intensity in 2050 is obtained from population density that, in turn, depends on the evolution of population and residential land-use. Residential land-use is projected to 2050 according to a model linked to population trajectories at the LAU level via the share-of-growth method. Finally, country-level intensity multiplied by the projected value of LAU residential area returns the electricity demand for every LAU. The results suggest that the amount of electricity required by cities depends on their land-use patterns, but with an evident between-and-within-country heterogeneity. The national average temperature does not provide significant effects over the evolution of electricity demand, highlighting the need for more detailed climate-related variables. This evidence poses significant challenges for the planning of future cities because it points out how the current patterns of land-use will need to be properly categorized with respect to the development of future electricity requirements
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
Exploring the relationship between public spending composition, firm productivity, and financial structure: evidence from EU manufacturing firms
No full textLAUREA MAGISTRALEQuesta tesi esamina la relazione tra la composizione della spesa pubblica e la produttività delle imprese, colmando una lacuna nella letteratura riguardo l'effetto a livello microeconomico della politica fiscale. Si indaga se l'allocazione della spesa pubblica verso funzioni produttive aumenti la Produttività Totale dei Fattori (TFP) e come tale effetto sia mediato da condizioni finanziarie e caratteristiche strutturali specifiche delle imprese.
Utilizzando un vasto insieme di dati panel a livello di impresa provenienti da aziende manifatturiere dell'UE e dati macroeconomici sulla spesa pubblica, si rileva che un aumento del livello della spesa pubblica destinata a Istruzione, Sanità e Affari Economici (EHEA) è associato a un incremento della Produttività Totale dei Fattori delle imprese. Tale risultato è coerente con l'ipotesi di crowding-in; l'assenza di effetti di crowding-out suggerisce una relazione di complementarità tra investimenti pubblici e privati. L'effetto non è omogeneo, poiché le condizioni finanziarie modellano l'impatto positivo per le imprese con maggiore esposizione al rischio e una salute finanziaria più debole, indicando che i vincoli finanziari inibiscono l'assorbimento dei benefici derivanti dagli investimenti pubblici.
Questi risultati, che si dimostrano robusti anche a fronte di una serie di specificazioni alternative, sottolineano che l'efficacia della politica fiscale dipende dalla qualità e dalla destinazione della spesa. La composizione della spesa conta più della sua dimensione aggregata, e il suo impatto a livello di impresa è influenzato in modo cruciale dalla salute finanziaria e dalla dimensione delle aziende.This thesis examines the relationship between the composition of public expenditure and firms’ productivity, addressing a gap in the literature concerning the micro-level effect of fiscal policy. It investigates whether allocating public spending toward productive functions enhances Total Factor Productivity (TFP) and how this effect is mediated by firm-specific financial conditions and structural characteristics.
Employing a large panel dataset of firm-level data from EU manufacturing firms and macroeconomic data on public expenditure, we find that an increase in the level of public spending allocated in Education, Health, and Economic Affairs (EHEA) is associated with an increase in firm Total Factor Productivity. This effect is consistent with the crowding-in hypothesis; the absence of crowding-out effects suggests a complementary relationship between public and private investment. This effect is not homogeneous, as financial conditions shape the positive impact for firms with high-risk exposure and weaker financial health, indicating that financial constraints inhibit the absorption of public investment benefits.
These findings, which are robust to a battery of alternative specifications, underscore that the effectiveness of fiscal policy relies on the quality and targeting of expenditure. The composition matters more than its aggregate size, and its impact at the firm level is crucially mediated by the financial health and size of firms
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
