Full text linkCarbon footprint of processed sweet cherries (Prunus avium L.): From nursery to market
Full text linkThe implementation of scientific studies can help to improve sustainable solutions in the agri-food sector according to current European policy. The present paper aims to evaluate the carbon footprint, according to ISO/TS 14067:2013, of 0.5 kg of sweet cherries packaged in clamshell made in polyethylene terephthalate (PET). The research assesses the supply chain, from agricultural (from nursery to dismantling) to the processing phase in firms located in the Apulia region. Results show a global warming potential over a fixed period corresponding to 100 years equal to 0.584 kg CO2eq, primarily deriving from agricultural management (0.442 kg CO2eq) and secondly from fruit processing (0.068 kg CO2eq). In the orchard phase, the main impacts derived from electricity consumed to pump groundwater used for irrigation and fertigation activities (15.84% of the total), transportation of manure (6.42% of the total), ploughing activity (4.83% of the total) and production of nitrogen fertilisers (4.28% of the total). Cherries processing in the collecting centre showed impacts from electricity consumption (5.57% of the total) and from waste deriving from damaged or non-conforming cherries (4.74% of the total). The PET clamshell production phase had an impact deriving principally from the use of PET granulate (0.0743 kg CO2eq). The study highlighted that manure administration and pruning activities contribute to decreasing greenhouse gas (GHG) emissions. Moreover, the sensitivity analysis showed that substitution of electricity-mix deriving from the Italian national grid with a photovoltaic plant lowered GHG emissions by 19%. The present study could contribute in providing suggestions to stakeholders and scholars in reducing GHG emissions and promoting more environmentally sustainable sweet cherry production practices

No full textAn input flow analysis for improved environmental sustainability and management of cherry orchards: A case study in the Apulia region
No full textItaly is the fourth top world cherries producer after Turkey, United States of America, Iran (Islam Republic of). The Apulia region is the largest sweet cherries (Prunus avium L.) producer at the national level and in particular one of the most produced cultivar is “Ferrovia”. This work is based upon a life-cycle approach, and is aimed at collecting and analysing the material and energy input-flows associated with a cherry orchard in the Apulia region. The study is intended both to serve as the starting base for performing the next phases of life-cycle inventory and environmental impact assessment, and to contribute in enhancing the current databases and scientific literature in this field. Furthermore, the study allowed the authors to highlight that the major inputs were due both to irrigation as large volumes of water used and diesel fuel consumption in particular to fertiliser and pesticide transportation and administration. The study can be considered as bases for further evaluation and reduction of the related environmental impacts
Navigating Lymphomas through BCR Signaling and Double-Hit Insights: Overview
Full text linkNon-Hodgkin's lymphomas (NHLs) are a heterogeneous group of lymphoproliferative disorders originating from B, T, or NK lymphocytes. They represent approximately 4-5% of new cancer cases and are classified according to the revised WHO system based on cell lineage, morphology, immunophenotype, and genetics. Diagnosis requires adequate biopsy material, though integrated approaches are used for leukemic presentations. Molecular profiling is improving classification and identifying prognostic markers. Indolent NHLs, such as follicular lymphoma and marginal zone lymphoma, typically pursue a non-aggressive clinical course with long survival. Aggressive diffuse large B-cell lymphoma (DLBCL) is the most common subtype. Recent studies have elucidated pathogenic mechanisms like MYC translocations and BCR pathway mutations. "Double hit" lymphomas with MYC and BCL2/BCL6 alterations confer a poor prognosis. Treatment approaches are evolving, with chemoimmunotherapy remaining standard for many indolent cases while intensified regimens and targeted agents show promise for refractory or high-risk aggressive disease. Continued elucidation of the genetic and microenvironmental underpinnings of lymphomagenesis is critical for developing personalized therapeutic strategies
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
Network impact of social innovation initiatives in marginalised rural communities
No full textThe marginalised rural communities are characterised by societal challenges, such as isolation, lack of job opportunities, land abandonment, low quality of life and generally low education. Social Innovation (SI) initiatives may represent an opportunity to strengthen relationships among the members of rural community, by means of the alteration of the existing social networks. In this way, more exchange of information is expected, paving the way for the creation of professional collaborations among firms and other actors. This paper aims at proposing a short-term evaluation framework of effectiveness of a SI initiative in terms of reconfiguration of the social network structure. The described empirical case study is VàZapp’, a rural hub located in Southern Italy, which provides innovative solutions to activate social relations amongst farmers, altering hence their network. A wellreferenced SI theoretical model, developed within the H2020 project SIMRA (Social Innovation in Marginalised Rural Areas), and the methodology of Social Network Analysis (SNA) were used to verify and measure quantitative and qualitative indicators affected by network intervention activated by VàZapp’ initiative. Results show
that this SI initiative worked effectively, leading to a +308% in the number of relations and +250% in social network density. In addition, an evident improvement in the quality of the social relations was found, especially in cases where there are direct engagements within VàZapp’. Outcomes suggest that supporting and promoting SI initiatives could become a central discussion point for the rethinking of rural development policies focused on regeneration of social relations’ structure
