Le piattaforme per la partecipazione digitale dei cittadini. Un'analisi basata sul modello di UE e Italia.

Il testo si propone di considerare e confrontare le esperienze europee e italiane di produzione, gestione, valutazione di piattaforme digitali per la partecipazione dei cittadini alle politiche pubbliche. Diversi obiettivi, modelli di costruzione, scelta delle finalità caratterizzano i due sistemi, europeo e italiano: il primo volto a sollecitare una partecipazione ideale verso il modello di Europa del futuro; il secondo è concretamente orientato all'esperienza di partecipazione, con participatory budget e allocazione di risorse per politiche pubbliche localizzate e con obiettivi tangibili (es. riqualificazione delle città). Dal confronto e dalla sintesi di queste due esperienze si possono trarre utili elementi teorici ed empirici per un ulteriore sviluppo delle piattaforme digitali per la partecipazione dei cittadini, in un contesto di crescente domanda partecipativa attraverso formati e strumenti non convenzionali.   The article proposes to consider and compare European and Italian experiences in the production, management and evaluation of digital platforms for citizens' participation in public policies. Different aims, models and goals characterize in different ways European and Italian systems. The first is aimed to promote an ideal participation coherently with the Europe vision for the future. On the contrary, the Italian one is concretely oriented towards the experience of direct participation, with specific budget and resources to support public policies with more tangible objectives (e.g. requalification of cities). From the comparison of these two experiences it is possible to derive some useful theoretical and empirical elements for the further development of digital platforms for citizen participation. This in a context of growing participatory demand through unconventional formats and tools.  Keywords: participatory platforms, EU, Italy, digital participation, citizens’ participatio

Second-Generation Muslim Youth Between Perception and Change: A Case Study on the Prevention of Radicalization

The following article presents the results of a research-action and an online communication campaign on the prevention of radicalization of second-generation young Italian Muslims as a part of a project called “Oltre” (the Italian acronym means “Beyond”) financed by European Union. After a short presentation of the four steps of the prevention communication model PKIC, a deepening on the radicalization factors, and a focus on the research-action methodology, the results of the research on some fundamental issues like the relationship with family and the relation with media and social media of the young interviewees, are shown. Finally, in the last part of the article, the interventions carried out by the second-generation young moderators of the social media campaign carried on Facebook and Instagram, are presented in the framework of the online communication campaign born out of the research-action to discuss if and how a prevention process and consequent change with regard to the radicalization factors took place

Le piattaforme per la partecipazione digitale dei cittadini. Un’analisi basata sul modello di UE e Italia

The paper aims to consider the UE and Italian experiences of production, management, evaluation of digital platforms for citizens' participation in public policies. Comparing tools and formats of the two models of developing civic participation through ICT platforms, the emerging analysis presents differences in objectives, in the construction models, in the choice of purposes. In the EU case, the system aims at soliciting an ideal civic participation towards the model of Europe of the future, progressively encompassing more and more citizens, while the Italian outline gears towards more concrete and localized experiences of participation, especially in city-level participatory budgets with tangible objectives of urban transformation. From the comparison and synthesis of these two experiences, some theoretical and empirical elements can be drawn, in order to sketch a further development of digital platforms for citizen participation, in a context of growing participatory demand through unconventional formats and tools

La biografia sociale

La biografia sociale ha a che fare con la storia di ciascuno di noi. È uno strumento utile per “tarare” il proprio punto di vista, per potenziare la propria capacità di riflessione sul proprio modo di agire e per sviluppare una più ampia e solida consapevolezza di sé. Può essere definita come un piccolo bilancio scritto della vita sociale di ognuno di noi, utile non tanto per chi legge ciò che ciascuno ha scritto ma, soprattutto, per lavorare su sé stessi. Un esercizio di scrittura da intraprendere per indagare il proprio modo di pensare e di percepire il mondo, per analizzare quegli elementi che ci contraddistinguono e che fanno sì che la nostra storia sia unica e irripetibil

Communication, digital media and future: new scenarios and future changes

Digital media, technology, new theoretical perspectives have revolutionized the ways of interacting among individuals, acquiring information and knowledge, teaching, behaving in multicultural society and so on and so forth. The impact of new ways of communicating, social media, political platforms on daily lives is evident. Multifaced and different aspects of these topics have been discussed in the VI World conference on Media and Communication (MEDCOM), which was supposed to be held in Cagliari, in May 2020, and it has been postponed to June 2021, online. During that year, communicating revealed even more relevant for citizen live. We assisted to the great importance of best practices in crisis communication, and the critical situations generated by fake news and information overload. Many different topics and fields were included in the conference and, in this volume, we collected 22 papers representative of the discussion, open to scholars from all over the world. The volume is organized in 8 sessions, each one exploring one specific topic: 1. Social Media: Impact, Future, Issues; 2. Public Sector Communication; 3. Politics, Ethics and Communication; Section: 4 Multiculturalism, Cultural Studies, Youth, and Gender Communication; 5 Media Education; 6 Media and Corporate; 7 Screen Cultures; 8 Communication and Covid-19 Pandemic. The last session has been added to the conference after the first postponement to favor analysis of the future development of communication and its complexity after the pandemic experience

Diabetes mellitus and ischemic heart disease. the role of ion channels

Diabetes mellitus is one the strongest risk factors for cardiovascular disease and, in particular, for ischemic heart disease (IHD). The pathophysiology of myocardial ischemia in diabetic patients is complex and not fully understood: some diabetic patients have mainly coronary stenosis obstructing blood flow to the myocardium; others present with coronary microvascular disease with an absence of plaques in the epicardial vessels. Ion channels acting in the cross-talk between the myocardial energy state and coronary blood flow may play a role in the pathophysiology of IHD in diabetic patients. In particular, some genetic variants for ATP-dependent potassium channels seem to be involved in the determinism of IH

Autonomous rotary mower versus ordinary reel Mower-effects of cutting height and nitrogen rate on manila grass turf quality

High-quality sports turfs often require low mowing and frequent maintenance. Sports turfs often consist of hard-to-mow warm season turfgrasses, such as zoysiagrass (Zoysia sp.) or bermudagrass (Cynodon sp.). Although autonomous mowers have several advantages over manually operated mowers, they are not designed to mow lower than 2.0 cm and are consequently not used on high-quality sports turfs. All autonomous mowers are only equipped with rotary mowing devices and do not perform clipping removal. An ordinary autonomous mower was modified to obtain a prototype autonomous mower cutting at a low height. The prototype autonomous mower was tested on a manila grass (Zoysia matrella) turf and compared its performance in terms of turf quality and energy consumption with an ordinary autonomous mower and with a gasoline reel mower. A three-way factor experimental design with three replications was adopted. Factor A consisted of four nitrogen rates (0, 50, 100, and 150 kghaL1), factor B consisted of two mowing systems (autonomous mower vs. walk-behind gasoline reel mower with no clipping removal), and factor C consisted of two mowing heights (1.2 and 3.6 cm). Prototype autonomous mower performed mowing at 1.2-cm mowing height whereas ordinary autonomous mower mowed at 3.6-cm mowing height. The interaction between the mowing system and mowing height showed that the turf quality was higher when the turf was mowed by the autonomous mower and at 1.2 cm than at 3.6 cm. Autonomous mowing not only reduced the mowing quality, but also reduced the leaf width. Lower mowing height induced thinner leaves. Nitrogen fertilization not only increased the overall turf quality, reduced weed cover percentage, but also reduced mowing quality. Autonomous mowers also had a lower energy consumption if compared with the reel mower (1.86 vs. 5.37 kWh/ week at 1.2-cm mowing height and 1.79 vs. 2.32 kWh/week at 3.6-cm mowing height, respectively). These results show that autonomous mowers can perform low mowing even on tough-to-mow turfgrass species. They could also be used on highquality sports turfs, thus saving time as well as reducing noise and pollution

Use of Flaming to Control Weeds in ‘Patriot’ Hybrid Bermudagrass

Flaming could be an alternative to the use of chemical herbicides for controlling weeds in turfgrass. In fact, the European Union has stipulated that chemical herbicides should be minimized or prohibited in public parks and gardens, sports and recreational areas, school gardens, and children’s playgrounds. The aim of this research was to test different doses of liquefied petroleum gas (LPG) to find the optimal flaming dose that keeps a ‘Patriot’ hybrid bermudagrass (Cynodon dactylon · Cynodon transvaalensis) turf free of weeds during spring green-up, but also avoids damaging the grass. Five LPG doses (0, 29, 48, 71, and 100 kgha–1) were applied in a broadcast manner over the turf experimental units using a selfpropelled flaming machine. This equipment is commercially available and usable by turfgrass managers. Treatments were applied three times during the spring to allow the maximum removal of weeds from the turfgrass. Data on weed coverage, density, biomass, and turfgrass green-up were collected and analyzed. Results showed that 3 weeks after the last flaming, the greatest LPG doses used (i.e., 71 and 100 kgha–1) ensured the least amount of weeds (range, 5–16 weeds/m2) of low weight (range, 7– 60 gm–2) and a low weed cover percentage (range, 1% to 5%), whereas the green turfgrass coverage was high (range, 82% to 94%). At the end of the experiment, the main weed species were horseweed (Conyza canadensis), field bindweed (Convolvulus arvensis), narrow-leaved aster (Aster squamatus), and black medic (Medicago lupulina). Flame weed control is a promising technique to conduct weed control in turfgrass. Further studies could be conducted to investigate the use of flaming in other species of warm-season turfgrasses

Steaming and flaming for converting cool-season turfgrasses to hybrid bermudagrass in untilled soil

Turfgrass species can be classified into two main groups: cool-season and warm-season species. Warm-season species are more suited to a Mediterranean climate. Transplanting is a possible method to convert a cool-season to a warmseason turfgrass in untilled soil. It generally requires the chemical desiccation of the cool-season turfgrass. However, alternative physical methods, like flaming and steaming, are also available. This paper compares flaming, steaming, and herbicide application to desiccate cool-season turfgrass, for conversion to hybrid bermudagrass (Cynodon dactylon x C. transvaalensis) in untilled soil, using transplanting. Two prototype machines were used, a self-propelled steaming machine and a tractor-mounted liquefied petroleum gas flaming machine. Treatments compared in this work were two flaming treatments and two steaming treatments performed at four different doses together with two chemical treatments with glufosinateammonium herbicide applications. The cool-season turfgrass species were tall fescue (Festuca arundinacea) and perennial ryegrass (Lolium perenne). The desiccation effect of the various treatments on cool-season turf was assessed by photographic survey 15 days after treatment. The percentage cover of hybrid bermudagrass was visually assessed at 43 weeks after planting. Steaming and flaming effects on both parameters were described by logistic curves. The highest doses of steaming and flaming almost completely desiccated cool-season turf, and similar hybrid bermudagrass cover was established by both the methods as the chemical application (50% to 60%). Thus both flaming and steaming may be considered as valid alternatives to herbicides aimed at turf conversion
