Roberto Fanfani 544 Economic Development, Rural Zones and Farms in China
Full text linkBecause of the growing influence of China, the rapid economic development and the transformation of Chinese society have attracted the attention of analysts, politicians and mass media. There are, however, many aspects of these changes that are less well known. This is not only because of the sheer size of China ‐ with a population of more than 1.3 billio
EFFICIENCY OF THE ITALIAN AGRI-FOOD INDUSTRY: AN ANALYSIS OF "DISTRICTS EFFECT"
Full text linkIn the course of the past decades major transformations in the Italian food industry induced considerable structural changes: on one hand, the creation of large industrial groups, with substantial input of foreign capital and, on the other, the concentration and geographic specialisation of numerous small and medium enterprises, with the formation of specific and typical agri-food local system (districts). To take account of the presence of food districts the analysis of the Italian food industry could not be conducted at national and regional level but it has to be studied at province and local level. It is also useful to analyse the food industry with reference to the different sub-sectors. We will conduct an in-depth analysis of the local systems (districts) of two sectors meat and fruit & vegetables processing. We will use balance-sheet data of the processing firms that were active in the meat (446 firms) and fruit & vegetables (227 firms) sub-sector in the years from 1996 to 1999. The analysis will consider the most significant balance sheet ratios, such as returns, productivity and labour cost in these local systmems. Then, we will consider the economic assessment of the firms belonging to local systems of the two sectors and compare with the non district firms. For the efficiency analysis will estimate a stochastic frontier production function in order to determine the "district effect". This analysis will also be directly correlated with investment in technological innovation. The economic and efficiency analysis confirms for many aspects the presence of a "district effect" in the Italian food industry.Food industry's efficiency, Food districts, Local development, Stochastic frontier production function, Meat and fruit sectors, Agribusiness, Industrial Organization,
Regional differencies in land holdings and land use: analyzing the First Agricultural Census.
No full textRapid economic development and the transformation of Chinese society have meant that China is receiving greater attention for their impact on future global affairs. However, many aspects of the current development are not well understood; not only the size of the country and its large population of almost 1.3 billion people, but also the scarce availability of information. In particular, knowledge of rural China, until recently, was incomplete and fragmented. This lack of knowledge has caused, among other issues, controversial and incorrect estimations of the agricultural sector’s capacity to meet the growing food demands of the nation. This in turn may have significant effects on world prices and the international agricultural market
Le dinamiche delle disuguaglianze spaziali in Cina a livello regionale e tra zone rurali e urbane
No full textLa rapida e rilevante crescita della Cina produce sempre maggiori disuguaglianze. La prima parte del paper si focalizza sull'analisi della convergenza economica nelle province e nelle zone rurali e urbane della Cina. Nella seconda parte si è superata l'analisi basata sul Pil andando a stimare un Indicatore di Sviluppo Multidimensionale per gli anni dei Censimenti 1996 e 2006
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
