    Is family farming educational? The Australian experience

    No full text
    The Australian rural landscape has been changing throughout history since the first European settlement. The progressive expansion of agriculture in the past centuries is responsible for its modification and diversification. Family farming has a relevant role in the Australian agriculture and food production, however in the last decades it has been facing a consistent decline, primarily because of economic and climatic reasons. This paper aims to retrace the historical development of agriculture in Australia and to analyse the current situation of family farming, by reporting the tendencies and the changed features, the educational and social aspects, and the interaction with the rural landscape. According to our research it emerged that family farming has been one of the major keys of the agricultural sector development in Australia and was deeply affected through history by internal and external factors such as globalization, neoliberalism, immigration and climatic conditions. Nowadays family farming is pivotal in the interface connection between modern societies and rural environment. In fact it is also becoming an important component of national tourism, with the birth and development of agrotourisms and holiday farms which in the past years have accounted for a considerable percentage of visits both from international and national people

    Outperforming esg stocks portfolio: A machine learning ranking model with catboots regressor

    The paper investigates whether outperforming ESG (Environmental, Social, and Governance) stocks can generate alpha over the S&P 500 through a machine learning (ML)-driven simulation. Leveraging advanced ML techniques, particularly the CatBoostRegressor model, the study explores the relationship between ESG factors and financial performance to construct a high performing, ESG-compliant portfolio. The findings suggest that incorporating ESG criteria not only supports sustainable investing but also enhances return predictability. However, backtesting reveals that portfolios more tolerant of lower ESG scores tend to yield higher short-term returns. A customizable threshold for ESG criteria allows the strategy to accommodate varying risk appetites, demonstrating that strategic flexibility can align ESG values with financial goals. This work highlights the transformative role of machine learning in sustainable investing, illustrating how ethical considerations and profitability can effectively coexist within a robust, ML-powered framework

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
