Emerging opportunities, challenges and constraints in the Chinese food industry
Full text linkChina is the world’s fourth largest country by total land area behind Russia, Canada and the USA. However, given the phenomenon of growing urbanization, the pressure on food demand for an increasing population as well as changing diet, China has had progressively to resort to imports, becoming a net importer of food. This scenario is set to continue and could result in a future Malthusian scenario. Resourcefulness, technology, research and modernization are factors on which China can improve, as they will have a key role in determining the ability of China, and also of the world, to feed their respective populations in the future. Improved efficiency and productivity, reform of land use rights, but also the policy of "going out" and “land grabbing” are some of the plausible strategies that the country could improve on to avoid an inexorable stabilization or, at worst, a decline in domestic production, as well as taking into account the impact of climate change on agricultural commodities.
Starting from these premises, this study, based on three core areas (food production, consumption and trade), aims to analyze the current situation, identifying opportunities, challenges and constraints that could prevent the development of the Chinese food industry. Initially, the Chapter provides an analysis of the context in which Chinese food companies evolve, analyzing supply (with a focus on the main food and beverages companies), and consumption and trade trends. Then, the main policies involving the food sector are analyzed. The obstacles that could affect the sustainable development of the Chinese food industry are included, focusing on increased urbanization, climate change threats and conflicts for limited natural resources (particularly land and water). A summary of the findings of this study and some recommendations for the Chinese food industry conclude the Chapter
EU enlargement: the impact on agricultural and food exports from selected Asian countries to the EU market - A gravity approach
Full text linkThe process of EU economic integration took place gradually. The 5th enlargement in 2004 was the largest expansion of the EU. It affected the agricultural sector notably due to the economic structure of the new members from Central and Eastern Europe. This chapter aims to examine the effect of the 5th enlargement on exports of agricultural and food products from 8 major Asian countries toward the EU market. The refined gravity model is employed, using annual data during 1999 to 2015 with 12 product groups. The empirical findings reveal that the total exports of agricultural and food products from Hong Kong and Korea reduce, whereas exports from Indonesia increase. There was no significant change in exports of total agricultural products and food from China, India, Japan, Malaysia and Thailand. However, changes in exports of certain products in various countries are found
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
