Institutionalizing innovation in welfare local services through co-production: toward a Neo-Weberian state?

Innovative practices based on the involvement of citizens as co-producers of welfare local services have been increasingly adopted by the public sector to effectively tackle emerging social problems. Despite the development in the literature on this subject, recent studies still do not clearly indicate which are the challenges for the institutionalization of such practices. By applying a governance lens to the analysis of co-production of local public services, this article aims to contribute to bridging this gap through the empirical analysis of the childcare experience in four European cities. More in detail, it debates the concepts of co-production and innovation in public service delivery within the context of the different waves of public administration reforms; and it investigates how three different sets of conditions – namely, state support and capacity; organizational cultures which support innovation; and integration with facilitative technologies – integrate to facilitate or hinder the institutionalization of co-production initiatives. The findings show that the enabling role of the state actor is a sine qua non to guarantee an institutionalization of these practices, particularly concerning the promotion of trust-building processes. Doing so, the article contributes to the international debate about the possible co-existing of the paradigms of public administration that are arising in the last decades to remedy the problems with the New Public Management; and it provides professionals working in public management and administration with key policy recommendations for the elaboration of new governance systems for the provision of social and welfare services

Understanding social innovation in refugee integration: actors, practices, politics in Europe

The so-called ' refugee crisis ' marked a crucial juncture in migration governance across Europe. Policy-makers and local communities face the challenge of receiving and integrating migrants (often in extremely vulnerable conditions) in a context of poor governance arrangements and rising skepticism, or even hostility. In the light of such a complex scenario, this special issue explores social innovation as a promising approach to refugee integration. Socially innovative practices are indeed based on the active engagement of policy-makers and assorted stakeholders-including target groups through co-creation. In the realm of asylum policies, social innovation can thus facilitate the meeting of refugees ' needs as well as the benevolence of receiving communities, ultimately strengthening social cohesion in regions of settlement. Families hosting migrants at home, community-based cooperatives, and self-managed social spaces are all instances of socially innovative practices that are often initiated by non-state actors but that might be upscaled and transformed into fully fledged public policies-especially by policy-makers at the local and regional levels. The special issue will focus on labor, housing, and social integration of refugees (especially in the stages after their first reception) in the context of Central European cities and regions. The purpose is to develop conceptual tools for evaluating and designing socially innovative practices that might ultimately improve the social innovation capacity of local and regional governments. As the ' social innovation ' concept risks to be ambiguous, the special issue will also allow researchers to develop a set of empirically grounded indicators for measuring social innovation capacity-especially based on the analysis of best practices that can be upscaled and replicated through mutual learning

Growing CeO2 Nanoparticles Within the Nano-Porous Architecture of the SiO2 Aerogel

In this study, new CeO2-SiO2 aerogel nanocomposites obtained by controlled growth of CeO2 nanoparticles within the highly porous matrix of a SiO2 aerogel are presented. The nanocomposites have been synthesized via a sol-gel route, employing cerium (III) nitrate as the CeO2 precursor and selected surfactants to control the growth of the CeO2 nanoparticles, which occurs during the supercritical drying of the aerogels. Samples with different loading of the CeO2 dispersed phase, ranging from 5 to 15%, were obtained. The nanocomposites showed the morphological features typical of the SiO2 aerogels such as open mesoporosity with surface area values up to 430 m2·g−1. TEM and XRD characterizations show that nanocrystals of the dispersed CeO2 nanophase grow within the aerogel already during the supercritical drying process, with particle sizes in the range of 3 to 5 nm. TEM in particular shows that the CeO2 nanoparticles are well-distributed within the aerogel matrix. We also demonstrate the stability of the nanocomposites under high temperature conditions, performing thermal treatments in air at 450 and 900°C. Interestingly, the CeO2 nanoparticles undergo a very limited crystal growth, with sizes up to only 7 nm in the case of the sample subjected to a 900°C treatment

Electromagnetic analysis and performance comparison of fully 3D-printed antennas

In this work, the possibility of directly prototyping antennas by exploiting additive manufacturing 3D-printing technology is investigated. In particular, the availability of printable filaments with interesting conductive properties allows for printing of even the antenna conductive elements. Three samples of a 2.45 GHz microstrip patch antenna have been 3D-printed by using different approaches and materials, and their performance evaluated and compared. In particular, the same dielectric substrate printed in polylactic acid (PLA) has been adopted in all cases, whilst copper tape and two different conductive filaments have been used to realize the conductive parts of the three antenna samples, respectively. Even if an expected radiation efficiency reduction has been observed for the conductive filament case, the comparative analysis clearly demonstrates that 3D-printing technology can be exploited to design working fully-printed antennas, including the conductive parts

EXPERIENCE IN MOBILE LASER SCANNING BY MEANS OF LYNX SYSTEM IN L’AQUILA CITY

The terrestrial laser scanner is an efficient topographical instrumentation used to acquire a redundant number of points distributed over a physical surface. The goal of laser scanning is the definition of very accurate models of the studied areas. In this way, deformations or changes can be monitored by means of repeated surveys in different epochs [Pesci et al., 2005; 2007]. The laser signal is characterized by highly collimated, monochromatic, and coherent radiation that is well suitable for very short impulse generation in the nanosecond scale. The operating methodology of a time-of-flight laser scanner is similar to a laser range-finder, measuring the time it takes a laser pulse to travel from a transmitter to the surface surveyed, and back to a detector device. The range d is computed using the relation d = ct / 2, where t is the time of flight and c is the speed of light. The advantage of this instruments is the laser beam deflection over a very accurate angular grid, that can be obtained by oscillating and rotating mirrors, thus providing a wide coverage area between adjacent points. Each point is collected into a local reference system consisting of the origin at the instrument sensor, well-known angular parameters, and very accurate measurements of range. Together with point coordinates (x, y, z) , radiometric values related to the surveyed object’s reflectivity can be calculated from returned signal energy. The maximum measurable range depends on the illuminated material roughness and color, and the laser wavelength [Fidera et al. 2004, Pesci and Teza, 2008]. Divergence values for new generation long-range scanners are extremely reduced, illuminating very small surface elements for each shot. The spot dimension increases linearly with the distance, and is always greater than the lower limit of the instantaneous field of view (IFOV) due to physical diffraction. Effective laser scanner characteristics are defined by a set of parameters, including: range resolution (depending on telemeter efficiency), single point measurement accuracy (depending on the internal electronic device, signal-to-noise ratio and critical time needed for pulse recognition), beam divergence (which defines the IFOV, depending on laser wavelength), and minimum angular step (depending on the internal mirrors calibrated system) [Wehr and Lohr 1999]. Overlap is the laser scanning strategy that can reduce errors, because redundant points are acquired belonging to the same illuminated area. A common overlap is obtained by fixing the ratio between spot dimension (the area illuminated by a single pulse with a given divergence) and angular step so that a given point is measured 10 times. For instance, if the divergence is 3 mrad and angular variation about 0.3 mrad, at 100 m distance, an element included in a 3 cm area is observed 10 times. The final result of a laser scanner application is a very dense point cloud, with radiometric reflectivity data for each point

Growing CeO2_2 Nanoparticles within the Nano-Porous Architecture of the SiO2_2 Aerogel

SOLUZIONE DINAMICA DELLA RETE ASSOGEO E INQUADRAMENTO EUREF-RDN

L’importante sviluppo avuto recentemente dai servizi GPS di posizionamento differenziale in tempo reale (RTK e VRS), ha permesso di diminuire in modo considerevole i tempi e quindi i costi per un rilievo topografico, questo senza incidere in modo significativo sulla precisione delle misure eseguite [Pesci et al., 2008]. L’infrastruttura che permette la realizzazione di questi servizi è costituita da una rete GPS di stazioni permanenti (SP) distribuite più o meno regolarmente su di una griglia la cui maglia, cioè la distanza tra le stazioni, è di qualche decina di chilometri. Assogeo S.p.a. a partire dal 2006 ha sviluppato nell’Italia centro-settentrionale una rete di stazioni permanenti (Fig. 1a) in grado di supportare i diversi servizi di posizionamento in tempo reale.Attualmente questa rete è costituita da 32 stazioni equipaggiate con ricevitore ed antenne geodetiche a doppia frequenza (Tab. 1) in continua espansione. Un singolo operatore, anche se equipaggiato di un solo ricevitore GPS, ha la possibilità di connettersi al centro operativo Assogeo ed eseguire il proprio rilievo topografico, in tempo reale. Il sistema di riferimento in cui vengono forniti i risultati del rilievo è quello su cui vengono calcolate le posizioni delle diverse SP, per questo motivo è importante che tale sistema di riferimento sia compatibile con quello utilizzato in ambito cartografico e topografico definito dall’Istituto Geografico Militare Italiano (IGMI). Inoltre, è necessario che la stima della posizione delle diverse SP sia la più precisa possibile e che quindi venga calcolata utilizzando tutte le informazioni acquisite da tali stazioni. A questo proposito IGMI ha istituito la Rete Dinamica Nazionale [RDN, Baroni et al. 2009] formata da 99 SP già operanti sul territorio e omogeneamente distribuite, offrendo un riferimento per allineare le diverse reti GPS per il servizio di posizionamento in tempo reale sorte sul territorio italiano. La rete RDN è a sua volta allineata ad un sistema di riferimento convenzionale ufficializzato in Europa, cioè il sistema ETRF2000 [Bruyninx et al., 2009], e riferito all’epoca 2005.0, secondo le più recenti direttive EUREF [Bruyninx, 2004, Kenyeres and Bruyninx, 2004]. Per uniformare le soluzioni allo stesso sistema di riferimento utilizzato dall’IGMI, è necessario quindi che anche le posizioni delle SP della rete Assogeo siano calcolate in ETRF2000 all’epoca 2005.0 e poiriportate al 2008.0. In questo lavoro vengono proposte e confrontate due strategie di calcolo per ottenere, in un modo semplice e intuitivo, il sistema di riferimento desiderato. Si tratta di procedure differenti che analizzano il medesimo insieme di osservazioni utilizzando lo stesso software, ma utilizzando strategie diverse, questo per verificare la reale precisione con cui può essere stimata la posizione di una stazione GPS permanente

GPS-based monitoring of land subsidence in the Po Plain (Northern Italy)

We use regional and local networks of continuously-operating GPS stations (CGPS) distributed in the northern–central part of the Italian peninsula to investigate the subsidence phenomenon of the Po plain sedimentary basin and vertical movements of the surrounding areas. The observations of 146 scientific and commercial stations are analyzed and compared, adopting analytical techniques widely used to study GPS coordinate time series. The use of simple antenna supports in commercial installations, instead of a more rigorous geodetic monument, does not seem to induce significant differences in the noise characteristics and in the amplitudes of annual and semi-annual periodic signals. The vertical velocity field deduced from 129 sites with observation time spans greater than one year, located in the Central–Northern Italian Peninsula, indicates the presence of two mainly subsidence areas: the Po Plain and the Arno Plain, while the sites located in the Alps and Apennine domains show relatively low uplift. The areas of the Po Plain monitored by GPS seem to indicate that the subsidence rate is constant or, in some cases, decreasing with respect to the values obtained from the last measurements, performed up to 2006 by means of both SAR and levelling techniques. Only the central part of the eastern Po Plain close to the Apennine border (Modena city area) is characterized by a peak in subsidence consisting in a velocity of about 15 mm/yr

Use of proton pump inhibitors and risk of ischemic events in the general population

BACKGROUND AND AIMS: A potential increased risk of cardiovascular events has been suggested for proton pump inhibitors (PPIs), the most commonly prescribed drugs for the management of upper gastrointestinal disorders. We aimed to estimate the risk of hospitalization for cardio/cerebrovascular (CV) events in a cohort of incident PPI users. METHODS: A nested case-control study was carried out using regional healthcare utilization databases. For each case (hospitalization for non-haemorrhagic CV event), up-to-five controls randomly selected from the cohort were matched by gender, age at cohort entry, and index date. Exposure was estimated as recency of therapy (current, recent and past users) and number of days covered. Adjusted conditional logistic regression was used to estimate the association between exposure and outcome. RESULTS: Among new PPI users, we identified 17,832 cases and 89,160 controls (males 64.9%; mean age 58.9 years). Cases showed a significantly higher prevalence of use of drugs for diabetes, hypertension and hypercholesterolemia than controls. Risk of CV events was significantly higher for current (OR 1.61; 95%CI 1.55-1.68) and recent users (OR 1.15; 95%CI 1.06-1.26) compared to past users. Analogous results were found stratifying for cardiovascular (ORcurrent 1.71; 95%CI 1.63-1.81) and cerebrovascular events (ORcurrent 1.43; 95%CI 1.34-1.54). The increased risk was confirmed in subgroups by antithrombotic, statin use, or exposure duration. The same analysis for H2-antagonists use showed no significant results. CONCLUSIONS: In primary care setting, PPI use was independently associated with increased risk of first-time cardiovascular event, consistent with the evidence that PPIs adversely impact vascular function, underlying the need to promote appropriate prescribing of these drugs
