How machine learning changes Project Risk Management: a structured literature review and insights for organizational innovation
No full textPurpose - In the current economic scenario characterized by turbulence, innovation is a requisite for company's growth. The innovation activities are implemented through the realization of innovative project. This paper aims to prospect the promising opportunities coming from the application of Machine Learning (ML) algorithms to project risk management for organizational innovation, where a large amount of data supports the decision-making process within the companies and the organizations. Design/methodology/approach - Moving from a structured literature review (SLR), a final sample of 42 papers has been analyzed through a descriptive, content and bibliographic analysis. Moreover, metrics for measuring the impact of the citation index approach and the CPY (Citations per year) have been defined. The descriptive and cluster analysis has been realized with VOSviewer, a tool for constructing and visualizing bibliometric networks and clusters.Findings - Prospective future developments and forthcoming challenges of ML applications for managing risks in projects have been identified in the following research context: software development projects; construction industry projects; climate and environmental issues and Health and Safety projects. Insights about the impact of ML for improving organizational innovation through the project risks management are defined.Research limitations/implications - The study have some limitations regarding the choice of keywords and as well the database chosen for selecting the final sample. Another limitation regards the number of the analyzed papers.Originality/value - The analysis demonstrated how much the use of ML techniques for project risk management is still new and has many unexplored areas, given the increasing trend in annual scientific publications. This evidence represents an opportunities for supporting the organizational innovation in companies engaged into complex projects whose risk management become strategic
Comparative transcriptome analysis of two citrus germplasms with contrasting susceptibility to Phytophthora nicotianae provides new insights into tolerance mechanisms
No full textKey message: Host perception of Phytophthora nicotianae switching to necrotrophy is fundamental for disease tolerance of citrus. It involves an HR-like response, strengthening of the cell wall structure and hormonal signaling. Abstract: Stem rot caused by P. nicotianae is a worldwide disease of several important crops, including citrus. Given the growing awareness of chemical fungicides drawbacks, genetic improvement of citrus rootstocks remains the best alternative. However, the molecular basis underlying the successful response of resistant and/or tolerant genotypes remains poorly understood. Therefore, we performed a transcriptomic analysis to examine the differential defense response to P. nicotianae of two germplasmsâtolerant sour orange (SO, Citrus aurantium) and susceptible Madam Vinous (MV, C. sinensis)âin both the biotrophic and necrotrophic phases of hostâpathogen interaction. Our results revealed the necrotrophic phase as a decisive turning point, since it included stronger modulation of a number of genes implicated in pathogen perception, signal transduction, HR-like response, transcriptional reprogramming, hormone signaling, and cell wall modifications. In particular, the pathogen perception category reflected the ability of SO to perceive the pathogen even after its switch to necrotrophy, and thus to cope successfully with the infection, while MV failed. The concomitant changes in genes involved in the remaining functional categories seemed to prevent pathogen spread. This investigation provided further understanding of the successful defense mechanisms of C. aurantium against P. nicotianae, which might be exploited in post-genomic strategies to develop resistant Citrus genotypes
BUILDING INTERSUBJECTIVITY AT A DISTANCE DURING THE COLLABORATIVE WRITING OF FAIRYTAILS.
No full textThis paper introduces intersubjectivity as a concept playing a crucial role in collaborative tasks, even when performed between partners at a distance. Two 5th grade classes from two European countries (Italy and Greece), collaborated in writing fairytales inspired by philosophically relevant issues. The software supporting the task is an asynchronous virtual environment. Videos recorded in the Italian class and materials posted on the platform were analyzed using qualitative approaches and discourse analysis. The case-study discussed shows how the construction of intersubjectivity at a distance is a complex process involving many aspects. The main results highlight how participants: (a) use the narrative structure as a pre-requisite to build an intersubjective space where partners representation plays an important role; (b) exploit to a high degree the intellectual reasoning needed to accomplish the task in a truly collaborative way; (b) attain a fine tuning of reflective and metacognitive skills fostering a genuine interdependency during the task. Within this process, computer mediation amplifies the partners ‘‘presence’’ all through the creative writing process, expanding [Bruner, J., 2002. Making stories: law, literature, life. Farrar Straus & Giroux] definition of writing as an activity where the ‘‘audience’’ plays a fundamental role as a ‘‘co-author’’
EFFICACY OF A NEW SO2 GENERATOR PAD IN MAINTAINING POSTHARVEST QUALITY OF TABLE GRAPES
No full textGray mold is the most damaging postharvest disease of table grapes, due to the ability of
the causal agent, Botrytis cinerea Pers., to adapt to different environmental conditions.
A success factor in long-term storage of table grapes is the application of SO2 generator
pads. Our research aimed at testing the activity of a new SO2 generator pad (Decco,
Italia) on gray mold and quality of table grapes cv. Italia and Red Globe stored for 90
days. The test involved the application of the pad in three different moments: in the
field, prior to precooling, and immediately after precooling. In addition, three different
bags were used for packaging: perforated and unperforated plastic liners and the new
Decco MAP (modified atmosphere packaging) bag. At 30 days of storage, ‘Red Globe’
packed in the field or just before precooling with SO2 generator, showed no infection
by B. cinerea; while 23-33% of clusters were infected when the pad was inserted
after precooling, with no significant differences among the various plastic liners used.
Clusters cv. Italia showed a similar trend but a lower disease incidence as compared
to ‘Red Globe’, with a maximum of 10% of infection in presence of SO2. The highest
incidence of rots was recorded at 90 days on cv. Red Globe with increasing values
moving from perforated to unperforated plastic liners and the new Decco MAP bag. In
absence of SO2 generators, the infections on both cultivars reached 100%. Clusters of
‘Italia’ and ‘Red Globe’ packed with Decco MAP showed the best quality
