MOTIVAZIONI, VALUTAZIONE E PROSPETTIVE NELLA PARTECIPAZIONE DEGLI AGRICOLTORI ALLE MISURE AGRO-AMBIENTALI:ANALISI QUALI-QUANTITATIVA SU UN CAMPIONE DI AZIENDE LOMBARDE
Full text linkAgro-environmental measures (AEMs) are policy instruments in the European Union that pay farmers for voluntary environmental commitments and protection of the European countryside.
The first AEMs were introduced by Reg. 2078/1992, thank to the MacSharry Reform. In this time they were “accompanying measures” and they were used to sustain rural income after decoupling and the abolishment of internal price support.
In the following programming period it became mandatory to every Member State to consider Agro-environmental measures part of their Rural Developing Programs and they became one of the most important instrument of the EU for rural areas.
Investigating literature about AEMs, we understand that the determinants of farmers’ participation were not only to be searched on farm structure and farmers’ characteristics, but also in personal attitudes using the Ajzen’s Theory of Planned Behavior (1991).
We collect 227 questionnaires of farmers participating in Agro-environmental measures in Lombardy during the last programming period in order to evaluate the perceptions of the respondents on the policy and explore motivations that drive farmers in the participation, evaluating both farm structural factors and their attitudes.
The study is composed by two main parts: one is focused on the construction of the identikit of the “standard participant” through a Likert scale survey and a qualitative analysis, and the other one is focused on modeling factors affecting the subscription of agro-environmental contracts.
In the first part, farmers answer questions concerning their perceptions about the role of conventional and environmental friendly agriculture, the impact of AEMs in their daily practices and economic aspects associated with them. They identify the reasons that push them to participate, the functions of the farm and the future they imagine for their business.
Through a classifications of farmers using personal and farm characteristics, we subdivides the sample and we try to understand how this parameters influence the answers and to typify the AEMs’ participant.
In the second part we implemented a logit model in order to answer the question “which are the determinants for the participation in agro-environmental measures in the next programming period?”, matching farm characteristics and farmers’ personal attitudes.
Farmers choose to participate in AEMs for environmental reasons and to value their own production on the market. Most of them are interested in increasing their income through the measures.
They are strongly aware of agriculture’s role of environmental manager and public goods producer but they aren’t satisfied with the recognition that is given by the decision-maker. In particular farmers criticize the Administration for procedures, bureaucracy and inspection but, finally, they want to continue to participate in AEMs.
Factors affecting the participation are linked to farm characteristics, such as its UAA or its membership to organic farms, and to the farmers perceptions on some issues, such as stiffness of control and satisfaction on the environmental performances of the measures
Marketing margins of food products in European countries using input-output tables
No full textThis paper computes marketing margins of EU-27 agri-food systems using Input-Output tables (IOTs); such estimation is more accurate than those yielded using macroeconomic aggregated data from national accounts. Some relevant economics flows are then observables: a) Exchange relationships among activity branches of agri-food system; b) Production uses splitted between intermediate and final consumption; c) Value and variation of whole margins for branch and for whole system; d) margins variations during the strong fluctuation in raw agricultural prices (price spike).
When chain-linked price tables will be available for more years it will be possible to separate the price component and quantity component of value change
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
