Valutazione di sostenibilità ambientale dei nanomateriali
Le numerose attività di R&D sui nanomateriali (NM) stanno portando allo sviluppo di nuovi prodotti e applicazioni, anche se ancora sussistono importanti lacune di conoscenza sul loro comportamento (chimico-fisico e di interazioni biologiche). Le metodologie di Life Cycle Assessment e di Risk Assessment risultano molto utili al fine di valutare e supportare uno sviluppo tecnologico sostenibile e sicuro. Lo studio qui presentato, parte del progetto Europeo Nanohex , punta alla valutazione degli impatti di una tecnologia emergente basata sui NM, attraverso un confronto con il sistema tradizionale, e l’analisi di benefici, svantaggi e potenziali margini di miglioramento. L’articolo presenta il contesto dello studio e l’approccio metodologico
The experience of the first industrial symbiosis platform in Italy
This paper reports the activity, promoted by the Italian agency for new technologies, energy and sustainable economic development (ENEA), in the framework of the project for the development and implementation of the first Italian Platform for Industrial Symbiosis implemented in Sicily (2011-2015). The goals of the project were: to provide a methodology and an instrument for industrial symbiosis implementation at regional scale, to implement a IS Platform as a support to SMEs to individuate symbiosis opportunities in the region. The whole approach includes: network activation, platform architecture design and implementation, analysis of the productive sector in Sicily, data collection and companies involvement. In particular the paper focuses on the activities developed for companies’ network creation trough a preliminary analysis of the predominant productive sectors followed by the organization of operative meetings in Sicily for companies’ involvement, analysis of potential synergies and resources sharing, and finally platform population. During the first two meetings more than 80 SME were linked giving rise to almost 400 output resources and almost 180 input resources. More than 690 potential matches were found between the participating enterprises showing interesting opportunities both for substituting resources with waste products in real and virtual cases and for sharing waste management services and infrastructures. The discussion occurred during the meeting has remarked the significance and the consequences of the regulatory and control system on IS application, underlining the necessary participation of local stakeholders and control authorities. It has also emerged the need to identify predominant productive activities in well-defined territorial contexts where to investigate the specific/local tangles taking into account legislative and technical-economic feasibility. Technical dossiers on three main resource streams (wastes from processing stone materials; plastics and agro-industrial wastes), which may generate the more interesting potential synergies, are being processed. These dossiers include European, Italian and regional regulations, guidelines, technical standards, logistic and economical aspects useful for supporting companies in synergies implementation. Results of this activity will also be used to improve the algorithm in the platform to find synergies. © 2015, Gh. Asachi Technical University of Iasi. All rights reserved
Gastrointestinal: An unusual rectal finding in a patient with ulcerative colitis
A 67‐year‐old man, with an acute flare of severe ulcerative colitis, on therapy with azathioprine for steroid‐dependent disease for 6 years was referred to our Inflammatory Bowel Disease Unit in 2015 because of severe anal pain and bloody diarrhea. Rectosigmoidoscopy showed multiple inflammatory pseudopolyps, erosions, and, close to the anal verge, a large ulceration of about 5 cm with irregular border (Fig. 1). Histology of the lesion showed a framework compatible with active severe ulcerative colitis. He underwent a pelvic magnetic resonance imaging, which excluded the presence of complications (i.e. abscess or neoplasia). Thereafter, after a negative screening (hepatitis B virus DNA load in the blood was lower than 1000 copies/mL with negative Epstein–Barr virus [EBV] immunoglobulin M), infliximab 5 mg/kg i.v. was started. However, the patient was admitted to the Neurology Department because of neurological changes (psychomotor retardation, confusional state, asthenia, and tremors). A diagnosis of postinfectious encephalitis from EBV reactivation (EBV‐DNA 2378 copies/mL; microbiological investigations on liquor were negative) was performed, and acyclovir therapy was started with rapid resolution. Infliximab was stopped, and due to the severe persisting condition, a proctocolectomy was performed. The histological report was positive for a typical complication associated to inflammatory bowel disease (IBD) patients on thiopurine treatment that is colorectal lymphoma (Fig. 2)

The Adherence to Infusible Biologic Therapies in Inflammatory Bowel Disease Patients during the COVID-19 Pandemic: Is It Really a Problem?
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
Dispelling the Myths Behind First-author Citation Counts
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
Bibliographics for the 983 eprints in the live archives of E-LIS : trends and status report up to 7th July 2004, based on author-self-archiving metadata
The priority for ideas and philosophy related to "Network Theory" have been traced back and documented by Braun(2004),and credit goes to Karinthy(1929).The IT has empowered to realise it, as the most practical phenomena and it is no more a humour. The OAI (Open Archives Initiatives)and ACIS (Academic Contributor Information System)are progressive in the direction ,which may lead to realise the "Collective Genius" at global level. Focus of present study is on Author-Self-Archiving (A-S-A)Metadata of the 983 Eprints in the Live Archives of the E-LIS (EPrints of Library and Information Science),which were approved till 7th July 2004.The A-S-A Metadata was used for librametric analysis. Self-explanatory bibliographics are illustrated.The highlights include: Conference papers (34%); highest approval, June 2004 (28%); published archives (76%);not refereed (52%); not in public domain (60%); highest self-archiving-author (De Robbio, Antonella).The Nos. of EPrints having single JITA domain specifications were: Theoretical and general aspects of libraries and information(27); Information use and sociology of information(80);Users,literacy and reading(13);Libraries as physical collections(30);Publishing and legal issues(57);Management(13);Industry, profession and education(36);Information sources, supports, channels(113) ; Information treatment for information services, Information functions and techniques (101); Technical services libraries, archives and museums(25); Housing technologies(1); Information technology and library technology(92); and Inter-domainery (395) i.e. having specifications of two or more than two JITA classes
Characterization of 4-nonylphenol-degrading bacterial consortium obtained from a textile wastewater pretreatment plant
4-nonylphenol (4-NP) isomers are toxic and recalcitrant compounds often resulting, together with short chain NPnEO, from ethoxylated nonylphenol (NPnEO) biodegradation in conventional activated sludge plants. In this work, a microbial consortium, defined as Consortium A, capable of removing 100 mg/L of 4-NP with no accumulation of metabolites with aromatic moiety was isolated from textile wastewaters after enrichment with 4-NP. The consortium showed remarkable degradation activities towards several short chain NPnEO congeners. Culture dependent techniques were used to isolate from the consortium twenty-six strains assigned to seven different ARDRA groups. Two- and three-member co-cultures were prepared with the strains showing highest 4-NP degrading capabilities, but neither the single strains nor the co-cultures were as efficient in 4-NP degradation as Consortium A. FISH was used to characterize the microbial composition of Consortium A: it evidenced a strong occurrence of Proteobacteria and, in particular, of Gammaproteobacteria along with a relevant stability of the culture. Therefore, the isolated consortium has the potential of being used in the development of a biotechnological process for the tertiary treatment of effluents of activated sludge plants fed with NPnEO contaminated wastewaters
PERCEIVE project - Deliverable D3.4 "Report on the statistical analysis of communication efforts’ impact and effectiveness on citizens’ awareness and appreciation of EU-financed projects"
Why is a focus on policy communication relevant to the practice and study of European integration?
Over the two last two decades, no clear pattern seems to have emerged linking the efforts of the
European Union (EU) to foster local development and reduction of disparities with a generalized
increase in the levels of European identity. This constitutes a relevant challenge for both policy
makers and local implementers as well as for students of the European integration process. In this
context, it is surprising how little attention has been paid to the potential role of cohesion policy –
the EU’s largest investment policy aimed at promoting regional development and reducing
disparities.
Based on a recognition of previous research and direct experience acquired through interaction
with practitioners of the cohesion policy field, in this report, we point out the importance of
‘awareness’ and ‘appreciation’ (of EU efforts) by EU citizens. This means that, albeit not a general
rule, those who are aware of the policy often appreciate EU developmental policies and, when these
two conditions are matched with each other, tend to fell more European. In managerial terms, this
gap between institutions and citizens points to the centrality of policy communication. That is, we
need to better understand the mechanisms and outcomes of communicating policy in todays’
practice of policy implementation.
Accordingly, this report aims at increasing our understanding of a number of strategic aspects
connected with the task of communicating EU regional cohesion policy at the local level. In more
detail, two main aspects are dealt with: First, the extent to which local communication activities
take part in a wider international discourse (i.e. through topics). Here, we expand our previous work
(i.e. see PERCEIVE deliverables 5.3 and 3.3) on communicating EU cohesion policy through social
media by analyzing contents generated by Local Managing Authorities’ (hereafter referred to as
LMAs) use of Facebook. And second, the impact and effectiveness of communication efforts (i.e. the
effect of the amount of communication investments and the content of communication activities
on citizens’ awareness of EU policies and appreciation of EU actions). Inquiring this aspect entailed a
statistical analysis of the association between communication efforts which LMAs disseminate the
aims and accomplishments of regional cohesion policy on the one hand, and awareness as well as
appreciation of the policy by EU citizens on the other hand. The outcomes of the social media
analysis described as the first aspect above are also included as variables of the statistical analysis of
the second focal aspect
