Sostenibilità e competitività aziendale: analisi economica di una innovazione per il miglioramento della shelf life dei prodotti ortofrutticoli
Get PDFLo spreco alimentare è uno tra i temi più dibattuti dell’ultimo decennio e rappresenta una priorità dell’agenda politica di tutti i Paesi. Con il moltiplicarsi degli studi sull’effettiva dimensione di questo fenomeno, si è registrata negli ultimi anni un’attenzione via via crescente da parte della comunità scientifica, delle istituzioni e della società civile ma ciò nonostante lo spreco alimentare fa registrare, ancora oggi, dati allarmanti e, una preoccupazione ancora maggiore, è la paradossale coesistenza di alti volumi di FLW e povertà alimentare.
Questo lavoro si è soffermato sulla riduzione della perdita dei prodotti ortofrutticoli nella fase di post raccolta, in modo particolare sullo spreco che si verifica come conseguenza della modalità di confezionamento di prodotti, attraverso l’introduzione di una innovazione che, sulla base dei test di laboratorio, consente di ottenere ragguardevoli risultati in termini di miglioramento della shelf life: il BlowDevice® (BD), valvola sviluppata da Di Renzo et. al. e coperta da brevetto nazionale ed internazionale, che, consentendo il flusso bidirezionale dei gas, fornisce proprietà traspiranti agli imballaggi per prodotti ortofrutticoli freschi.
Obiettivo della presente tesi è verificare la sostenibilità, dal punto di vista economico, dell’investimento connesso all’adozione del dispositivo BlowDevice® da parte dell’Organizzazione di Produttori “Armonia” con sede a Battipaglia (SA), che è una delle maggiori del Mezzogiorno d’Italia, nata nel 2009 dall’unione di alcune tra le più grandi Organizzazioni di Produttori del Sud Italia.
La stima del potenziale di mercato di questa nuova tecnologia, applicata alle confezioni di alcuni prodotti ortofrutticoli individuato come target (ciliegie, fragole, kiwi, uva tavola, rucola), è stata condotta mediante un confronto tra lo scenario di base, dato dall’assenza dell’investimento, e lo scenario alternativo caratterizzato dall’introduzione di questo nuovo metodo di confezionamento.
L’adozione del BlowDevice® incide sui costi operativi dell’azienda, determinando un aumento sia dei costi fissi che dei costi variabili, tuttavia determina una riduzione della quantità di prodotto non commercializzata perché deteriorata durante il trasporto verso la grande distribuzione, incrementando i ricavi di vendita.
I risultati ottenuti hanno evidenziato da un lato che l’introduzione del BD® richiede un incremento del prezzo di vendita dei prodotti almeno pari al 4,98%, tuttavia, dai dati raccolti, si può vedere che, se l’azienda riuscisse a consegnare tutti i prodotti in ingresso, azzerando quindi gli sprechi, il prezzo di pareggio sarebbe inferiore a quello dello scenario di base, e, sulla base di test di laboratorio relativi al BD®, tale risultato è conseguibile se la frutta confezionata è in buono stato di conservazione a dimostrazione di come è importante che l’intera catena di approvvigionamento sia efficiente.Food waste is one of the most debated topics of the last decade and represents a priority on the political agenda of all countries. With the increasing number of studies on the actual scale of this phenomenon, in recent years, there has been growing attention from the scientific community, institutions, and civil society. However, food waste still shows alarming figures today, and an even greater concern is the paradoxical coexistence of high FLW volumes and food poverty.
This work focused on reducing the loss of fruit and vegetable products in the post-harvest phase, particularly on waste resulting from packaging methods, by introducing an innovation that, based on laboratory tests, achieves remarkable results in terms of shelf-life improvement: the BlowDevice® (BD). This valve, developed by Di Renzo et al. and covered by national and international patents, enables the bidirectional flow of gases, providing breathable properties to packaging for fresh fruit and vegetable products.
The objective of this thesis is to assess the economic sustainability of the investment related to the adoption of the BlowDevice® by the Producer Organization “Armonia”, based in Battipaglia (SA). “Armonia” is one of the largest producer organizations in Southern Italy, founded in 2009 through the union of some of the most significant producer organizations in the region.
The market potential estimation of this new technology, applied to the packaging of selected target fruit and vegetable products (cherries, strawberries, kiwis, table grapes, arugula), was conducted by comparing the baseline scenario—where no investment is made—with an alternative scenario featuring the introduction of this new packaging method.
The adoption of BlowDevice® impacts the company’s operating costs, leading to an increase in both fixed and variable costs. However, it also reduces the amount of unsellable products that deteriorate during transportation to large-scale retail distribution, thus increasing sales revenues.
The results show that implementing BD® requires an increase in the selling price of products by at least 4.98%. However, the collected data indicate that if the company were able to deliver all incoming products, thereby eliminating waste, the breakeven price would be lower than that of the baseline scenario. Based on laboratory tests related to BD®, this outcome is achievable if the packaged fruit is well-preserved, demonstrating the importance of an efficient supply chain
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
