Measuring and understanding the drivers of agricultural innovation: evidence from Ireland
No full textDespite the well-known importance of innovation to productivity growth in the agri-food sector, very few studies have attempted to measure farm-level innovation. This article contributes to the literature by developing an agricultural innovation index that goes beyond measuring innovation through adopted technologies. Based on this index, drivers and barriers of innovation are assessed. The findings reveal that innovation efforts differ between farm systems. Moreover, farm size and intensity, access to credit and agricultural education foster innovation, while increasing age and working off-farm hinder innovation. The paper concludes with policy recommendations to facilitate innovation in the agri-food sector
What drives innovation in the agricultural sector? A spatial analysis of knowledge spillovers
No full textThis article analyses the spatial concentration of agricultural innovation in Ireland. Influenced by the importance of knowledge spillovers, the roles of key innovation drivers are discussed. The analysis reveals a clear spatial concentration of agricultural innovation and while some of this variation can be explained by the spatial concentration of the sector, there are also other factors at play that drive the spatial distribution of innovation. More specifically, the distributions of research, education and advisory services show a similar spatial pattern to agricultural innovation, providing support for the existence of regional knowledge spillovers
Democracy Matters: lessons from the 2015 Citizens’ Assemblies on English devolution
Get PDFThe Citizens’ Assembly pilots on local democracy and devolution were the first of their kind in the United Kingdom. Organised by Democracy Matters — an alliance of university researchers and civil society organisations led by Professor Matthew Flinders — and funded by the UK’s Economic and Social Research Council, the Assemblies took place in Southampton and Sheffield towards the end of 2015
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Food Security in Haiti After the 2010 Earthquake: Analysis and Evaluation of NGO Relief Efforts
No full textHaiti suffered an earthquake in January of 2010, bringing instability and widespread hunger. Even after two years, many Haitians lack food security, and one must look at the failings of the Haitian government and those who attempted to provide aid. Major aid organizations such as the Red Cross, World Food Program, the United Nations Children's Fund and the Food and Agriculture Organization stepped in to provide disaster assistance. Unfortunately, these organizations failed to effectively coordinate and communicate with the Haitian government and other relief organizations, resulting in haphazard distribution of food aid and no commitment to long term food security (Cullen & Ivers, 2010, p. 63). The Haitian government also had plans for reconstruction that, while very similar to non-governmental organizations (NGO) actions taken after the earthquake, were not always in line with these organizations (Government of the Republic of Haiti, 2010, pg. 23). Other nations impacted by earthquakes such as New Zealand, Japan and the Dominican Republic, which shares an island with Haiti, have recovered quicker after natural disasters. Disaster relief organizations and other nations can learn from the shortcomings of the food security response to the Haitian earthquake. Going forward, Haiti has many problems to contend with and they must improve their food security. Implementation of more effective strategies will help countries better manage natural disasters in the future
