    In disaster situations, such as floods or earthquakes, the elderly and people with disabilities are particularly vulnerable and require additional attention. However, they are often neglected in existing municipal disaster emergency plans, particularly when such people live alone instead of in a care institution as their location is often undetermined in disaster situations or the information exists (e.g. if the people receive social services or if neighbours are aware of people in need in their vicinity) but is not structured in a way that is usable for civil protection emergencies. Up-to-date information for helpers and a community that is aware of this particular challenge for disaster relief can alleviate this problem. The paper presents the first results of the research action carried out by a joint partnership (universities/Italian, German and Danish voluntary organizations) highlighting: 1) which aspects are relevant for identifying the condition of vulnerability of the elderly and disabled; 2) how to develop a system for vulnerable people in integrated risk management mechanisms through local networks and volunteers; and 3) what is the added social value of volunteering in prevention and support for the elderly and disabled and the contribution to strengthening the resilience of local communities

    The digital inclusion of vulnerable people in the community development process. Action research in Reggio Calabria in southern Italy

    This paper presents the first results of a research action in progress in the Pellarodistrict of Reggio Calabria (South Italy). This action research aimed to activate a process of community development within a city district with both a large vulnerable population and a high density of organised crime employing a theoretical approach thatrefers to urban and media practices and the mediated construction of social reality (Blokland, 2017; Couldry, 2004; 2012; Couldry & Hepp, 2017; Stephansen & Trerè, 2020).The activation of the community development process focused on the interweaving of deep mediatisation and the daily life of people in the district (Hepp,2015; 2020). In particular, actions have been developed that have allowed the growth of social skills and digital/social skills among the most vulnerable people. From anedu-communication perspective (Barbas,2020), these people have been facilitated to become protagonists of the process of territorial and digital relational development also thanks to the use of participation and community platforms both of a commercial nature (e.g., Google Maps with some tweaks) and co-constructed by citizens and made easily accessible also to those who had fewer basic digital skills. Despite a high density of organised crime (’ndrangheta), no obstacles were impairing the development of digital/social relations, at least in this first phase of the work.We will examine three aspects, with particular attention within the paper: a) the ability to develop dual relationships (social and digital) within a peripheral, marginal and vulnerable community context such as that of Southern Italy; b) the deep interweaving between traditional and mediated communities (Hepp,2020) even if these mainly consist of vulnerable people; c) the potential of the digital media to meet specific needs of the population (Couldry,2012) ensures its realisation with the most vulnerable part of the population only if the latter is made the protagonist of its actions through voice processes (Couldry,2010) and bottom-up empowerment and edu-communication (Freire,1970; Barbas,2020)

    Social and digital vulnerabilities: The role of participatory processes in the reconfiguration of urban and digital space

    Get PDF
    In the Italian context, political and social participation in the urban dimension has experienced innovations to broaden the inclusion of citizens in public choices relating to citylife and to urban renovation. Participation found in the city a relevant space to experiment with innovation in the relationship between institutions and citizens, many initiatives advanced and developed over the years have had a powerful lever in technology: participatory budgets, consultations, public-private-non-profit partnerships. In other cases, specifically in peripheral realities, urban innovation has turned out to be detached from digital infrastructures and has benefited, rather, from the social infrastructures in the area. Civic committees, community foundations, collaboration agreements between citizens and authorities, and local community development experiences developed in peripheral contexts. Regenerating urban spaces is a political objective proposed with increasing emphasis by institutional bodies at the various levels of governance. Environmental, economic, social and urban planning intersect and overlap and often projects related to urban planning “on paper” prevail over issues related to urban communities “on territories”. Without adequate processes of participation and subjectivity of citizens living in urban contexts, no model of “urban renaissance” appears fully deployed, resulting in participatory processes that—at best—only allow for access logics in a neoliberal perspective. Through a qualitative methodology, the paper aims at presenting and investigating six case studies in major Italian cities (Rome, Naples, Milan, Turin, Florence, Reggio Calabria), in which democratic innovation and experimentation in civic engagement spread from the digital capital of citizens and the social organizations of the peripheral territory, with its specificities and its problems. In particular, the objective of the paper is to discuss and problematise the processes of participation involving and featuring vulnerable people within the reconfiguration of urban and digital spaces. Following Sutton and Kemp’s approach, we consider the relationship between urban spaces and marginal communities as central to a one-to-one relationship, fostering processes of urban inclusion. Combining participatory processes in liminal marginalized communities with an institutional push toward holistic urban regeneration may develop opportunities for active citizenship, overcoming the neoliberal paradigm of the city

    Metabolic and Hormonal Determinants of Glomerular Filtration Rate and Renal Hemodynamics in Severely Obese Individuals.

    OBJECTIVE: Renal function is often compromised in severe obesity. A true measurement of glomerular filtration rate (GFR) is unusual, and how estimation formulae (EstForm) perform in such individuals is unclear. We characterized renal function and hemodynamics in severely obese individuals, assessing the reliability of EstForm. METHODS: We measured GFR (mGFR) by iohexol plasma clearance, renal plasma flow (RPF) by 123I-ortho-iodo-hippurate, basal and stimulated vascular renal indices, endothelium-dependent and -independent vasodilation using flow-mediated dilation (FMD) as well as metabolic and hormonal profile in morbid, otherwise healthy, obese subjects. RESULTS: Compared with mGFR, the better performing EstForm was CKD-EPI (5.3 ml/min/1.73 m2 bias by Bland-Altman analysis). mGFR was directly related with RPF, total and incremental glucose AUC, and inversely with PTH and h8 cortisol. Patients with mGFR below the median shown significantly higher PTH and lower vitamin D3. Basal or dynamic renal resistive index, FMD, pulse wave velocity were not related with mGFR. In an adjusted regression model, renal diameter and plasma flow remained related with mGFR (R2 = 0.67), accounting for 15% and 21% of mGFR variance, respectively. CONCLUSIONS: CKD-EPI formula should be preferred in morbid obesity; glucose increments during oral glucose tolerance test correlate with hyperfiltration; RPF and diameter are independent determinants of mGFR; slightly high PTH values, frequent in obesity, might influence mGFR

    In athletes, spectral analysis of HR variability (HRV) has been shown capable to detect the adaptational changes in sympatho-vagal control attending physical training. So far, studies investigated autonomic nervous system (ANS) changes occurring with endurance training, whereas adaptations to markedly different exercise modes, for example, strength training, have never been investigated. We assessed the changes in cardiac ANS parameters during long-term training in weight lifters of the Italian team preparing for the European Championship, where athletes competed for obtaining the pass for Olympic Games. We investigated nine athletes. Subject trained 3 sessions/day, 6 days a week. The intensity of strength exercises varied from 70% to 95% 1 RM. Training load (TL) was calculated as: volume (min)  7 intensity (%1RM).All ANS parameters were significantly and highly correlated on an individual basis to the dose of exercise with a second-order regression model (r2 ranged from 0.96 to 0.99; P < 0.001). The low-frequency (LF) component of HRV and LF/HF ratio showed an initial increase with the progression of TL and then a decrease, resembling a bell-shaped curve with a minimum at the highest TL. The high-frequency (HF) component of HRV and R-R interval showed a reciprocal pattern, with an initial decrease with progression of TL followed by an increase, resembling an U-shaped curve with a maximum at the highest TL. These adaptations were at the opposite to those previously reported in endurance athletes. These results suggest that in Olympic weight lifters, ANS adaptations to training are dose-related on individual basis and that ANS adaptations are mainly sport-specific

    Effects of water stress on spectral reflectance of bermudagrass

    In the south-central Italy, during summer rainfall does not supply a sufficient amount of water. Therefore, irrigation management during dry periods is important for maintaining turf quality. The hybrid bermudagrass (Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt–Davy) is known to represent the dominant warm-season turfgrass in warm to temperate climatic regions and its drought tolerance make bermudagrass a competitive turfgrass. A greenhouse experiment was conducted using uniform cores of hybrid bermudagrass, which were secured in a polyvinyl chloride cylinders and watered by constant sub-irrigation. The objectives of the present research were to measure the spectral reflectance with a new generation handheld spectroradiometer on hybrid bermudagrass and to explore various vegetation indices to be used as future detecting tool to study water stress in bermudagrass. Moreover, the potential uses of multivariate processing techniques for discriminating different water stress conditions in turfgrass has been investigated. Besides spectral indices, multivariate methods, although performed on a data set limited in terms of sample size, have shown a great potential for water stress monitoring in turfgrass and surely deserve further investigations. There are different indices that use distinct water absorption features independent of chlorophyll concentration, such as water index (WI = R900/R970) that has been reported to be a robust index of canopy water content and is used as an active indicator of changes in Leaf Relative Water Content (LRWC). Also, the ratio of WI with NDVI (WI/NDVI = (R900/R970)/((R800 − R680)/(R800 + R680)]) was found to be an effective indicator of water stress. Another vegetation index to detect water features is normalized difference water index (NDWI), designed to maximize reflectance of water by using green wavelengths. In our trial in bermudagrass the relationships studied, suggest that WI (900/970) and WI/NDVI, among the indices studied, are the more effective indicators of water stress. In fact, lower values of WI indicate higher water stress, while higher values of WI/NDVI indicate higher water stress levels

    Robotic mowing of tall fescue at 90 mm cutting height: random trajectories vs. systematic trajectories

    Get PDF
    Tall fescue (Schedonorus arundinaceus (Schreb.) Dumort.) is often managed with a cutting height ranging from 70 to 100 mm in ornamental lawns. Some autonomous mowers have been specifically designed to maintain mowing height in the same range. Generally, autonomous mowers operate by following random trajectories, and substantial overlapping is needed to obtain full coverage of the working area. In the case of tall grass, this may cause lodging of grass plants, which in turn may reduce turf quality. The introduction of a navigation system based on systematic trajectories has the potential to improve the performances of autonomous mowers with respect to machine efficiency and turf quality. With the aim of determining the effects of reduced mowing frequency and systematic navigation systems on turf quality and mower performances in terms of working time, energy consumption and overlapping, the performances of two autonomous mowers working with random and systematic trajectories were tested on a mature tall fescue lawn at 90 mm cutting height. The working efficiency was approximately 80% for the systematic trajectories and approximately 35% for the random trajectories; this was mainly due to the lower overlapping associated with systematic trajectories. Turf quality was slightly higher for the mower working systematically (a score of 8 using a 1–9 score with 1 = poor, 6 = acceptable and 9 = best) compared to the one working randomly (quality of 7 and 6 on a 1–9 scale with 1 = poor and 9 = best). No appreciable lodging was observed in either case. For tall, managed lawns, systematic trajectories may improve autonomous mowers’ overall performances

    Two naphthalene degrading bacteria belonging to the genera Paenibacillus and Pseudomonas isolated from a highly polluted lagoon perform different sensitivities to the organic and heavy metal contaminants

    Two bacterial strains were isolated in the presence of naphthalene as the sole carbon and energy source from sediments of the Orbetello Lagoon, Italy, which is highly contaminated with both organic compounds and metals. 16S rRNA gene sequence analysis of the two isolates assigned the strains to the genera Paenibacillus and Pseudomonas. The effect of different contaminants on the growth behaviors of the two strains was investigated. Pseudomonas sp. ORNaP2 showed a higher tolerance to benzene, toluene, and ethylbenzene than Paenibacillus sp. ORNaP1. In addition, the toxicity of heavy metals potentially present as co-pollutants in the investigated site was tested. Here, strain Paenibacillus sp. ORNaP1 showed a higher tolerance towards arsenic, cadmium, and lead, whereas it was far more sensitive towards mercury than strain Pseudomonas sp. ORNaP2. These differences between the Gram-negative Pseudomonas and the Gram-positive Paenibacillus strain can be explained by different general adaptive response systems present in the two bacteria
