Comparing proximity for couples of close airports. Case studies on city-airports in the pre COVID-19

Following the existing relationships between cities and airports, well depicted in the sectorial literature ((Thierstein and Conventz, 2018), (Tira et al., 2006), (Freestone, 2009), (Percoco, 2010), (Ventura et al., 2020), this paper aims to investigate the linkages between the touristic traffic of some airports and the related development of the cities in which they are placed. The chosen case studies regard different remote regions (ONU, 2018) of three different countries (Italy, Norway, Cyprus), considering couples of near airports (Dziedzic and Warnock-Smith, 2015). The paper focuses the analysis on four couples of near airports, two from the South of Italy (Bari and Brindisi in the Apulia Region; Palermo and Trapani in Sicily), one in the North of Norway (Bødo and Narvik in Hålogaland) and the last one in the Republic of Cyprus (Larnaca and Paphos). A GIS analytic methodology has been used to describe the differences between the different couples of airports. Managed by the GIS analytical evaluation, the purpose of this paper is to give support to the different theories about the development of couples of close airports, using geographic tools to support economic and financial planning ((Cook and Billig, 2017) (Graham, 2014), (AntonínKazdaa et al., 2017) (Young and Wells, 2011))]. There has been pointed out the results of the adopted methodology on the working Norwegian network system analysis

Value Creation Through Collective Intelligence: Managing Intellectual Capital

The contribution of intellectual capital to value creation beyond individual companies into wider society, as described in the fourth stage of intellectual capital research, is of particular relevance for the public sector where organizations have a stewardship responsibility. They should engage stakeholders into value co-creation by developing organizational and ecosystem collective intelligence through traditional as well as innovative tools such as online technologies. Yet, the relationship between intellectual capital and value creation often remains a relatively unexplored process within public administration. This paper focuses on the case study of a regional agency in Friuli Venezia Giulia, Italy, which is not only responsible for assistance, regulation and service delivery, but also for engaging its stakeholders and the public at large to disseminate knowledge to promote values and appropriate behaviour in the policy areas it is responsible for. The research looks at the role played by intellectual capital in the agency’s value creation strategies and how the agency’s structure and processes influence the development and management of intellectual capital in an effort to create value for its ecosystem. The research not only validates the existence of ecosystem frameworks in public administration and the key role played by intellectual capital in their design, creation and implementation, but it also highlights the need in the public sector for a defined role for intellectual capital, stakeholder engagement and collective intelligence in governance models. In particular, findings underline the need for new intellectual capital management systems based on a collective intelligence approach within multi-stakeholder co-creation frameworks in a public service ecosystem logic, reflecting the public sector’s evolving role and the new tools developed with the advent of new technologie

The colours of BL Lac objects: a new approach to their classification

We selected a sample of 437 BL Lac objects, taken from the RomaBZCat catalogue, for which spectroscopic information and SDSS photometry is available. We propose a new classification of BL Lacs in which the sources' type is not defined only on the basis of the peak frequency of the synchrotron component in their Spectral Energy Distribution (types L and H), but also on the relevance of this component with respect to the brightness of the host galaxy (types N and G, for nuclear or galaxy dominated sources). We found that the SDSS colour index u-r=1.4 is a good separator between these two types. We used multiband colour-colour plots to study the properties of the BL Lac classes and found that in the X-ray to radio flux ratio vs u-r plot most of the N (blue) sources are located in a rather narrow strip, while the G-sources (red) are spread in a large area, and most of them are located in galaxy clusters or interacting systems, suggesting that their X-ray emission is not from a genuine BL Lac nucleus but it is related to their environment. Of the about 135 sources detected in the gamma-rays by Fermi-GST, nearly all belong to the N-type, indicating that only this type of sources should be considered as genuine BL Lac nuclei. The J-H, H-K plot of sources detected in the 2MASS catalogue is consistent with that of the "bona fide" BL Lac objects, independently of their N or G classification from the optical indices, indicating the existence in G-type sources of a K-band excess possibly due to a steep, low frequency peaked emission which deserves further investigations. We propose to use these colour plots as a further tool for searching candidate counterparts of newly discovered high-energy sources.Comment: 11 pages, 7 figures.

Assessment of Correlations among Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL) and Cumulative Illness Rating Index (CI) Scores in the Elderly Patients with Femur Fractures: A Prospective Study

Background: The World Health Organization (WHO) has established that injury will be the second principal cause of the world disease onerous by the year 2020. Purpose: In this study comorbidity was evaluated with the Cumulative Illness Rating Index, (CI) and studied in relation to the functional status of the elderly participants, by considering: Activities of Daily Living (ADL), and Instrumental Activities of Daily Living (IADL), scores. Method: Ninety-five elderly patients with femur fracture were recruited for this study. A prospective investigation and evaluation of their comorbidity and their physical activity conditions was performed. Results: Correlations were evaluated between: ADL and CIRS values (r = 0.23); CIRS and IADL values (r = 0.24), and finally correlations between patients age and CIRS values (r = 0.09).Conclusion: No significant correlations were assessed to standardize the different score levels.

Nursing Perception on Patient Safety Culture: The Latest Methodological Approaches

Safety culture can be defined as “the values shared among organization members about what is important, their beliefs about how things operate in the organization, and the interaction of these with work unit and organizational structures and systems, which together produce behavioral norms in the organization that promote safety”. This literature review aimed to identify the latest methodological approaches quantifying patient safety culture perception among nurses. The available literature was searched from January 2018 to today . Eleven eligible works were found and analyzed and the main key concepts highlighted were: the research approaches to assess patient safety culture, the development of quantitative survey tools for data collection for further reproducibility and the levels of data aggregation for conducting data analyses. A cohesive body of literature of evaluation tools is requiring on patient safety culture among nurses which is still limited in the current literature.

Semi-Visible Dark Photon Phenomenology at the GeV Scale

In rich dark sector models, dark photons heavier than tens of MeV can behave as semi-visible particles: their decays contain both visible and invisible final states. We present models containing multiple dark fermions which allow for such decays and inscribe them in the context of inelastic dark matter and heavy neutral leptons scenarios. Our models represent a generalization of the traditional inelastic dark matter model by means of a charge conjugation symmetry. We revisit constraints on dark photons from $e^+e^-$ colliders and fixed target experiments, including the effect of analysis vetoes on semi-visible decays, $A^\prime \to \psi_i (\psi_j \to \psi_k \ell^+\ell^-)$. We find that in some cases, the BaBar and NA64 experiments no longer exclude large kinetic mixing, $\varepsilon \sim 10^{-2}$, and, specifically, the related explanation of the discrepancy in the muon $(g-2)$. This reopens an interesting window in parameter space for dark photons with exciting discovery prospects. We point out that a modified missing-energy search at NA64 can target short-lived $A^\prime$ decays and directly probe the newly-open parameter space.Comment: 41 pages, 22 figures, version published in PR

A panorama of new-physics explanations to the MiniBooNE excess

The MiniBooNE low-energy excess stands as an unexplained anomaly in short-baseline neutrino oscillation experiments. It has been shown that it can be explained in the context of dark sector models. Here, we provide an overview of the possible new-physics solutions based on electron, photon, and dilepton final states. We systematically discuss the various production mechanisms for dark particles in neutrino-nucleus scattering. Our main result is a comprehensive fit to the MiniBooNE energy spectrum in the parameter space of dark neutrino models, where short-lived heavy neutral leptons are produced in neutrino interactions and decay to $e^+e^-$ pairs inside the detector. For the first time, other experiments will be able to directly confirm or rule out dark neutrino interpretations of the MiniBooNE low-energy excess.Comment: 35 pages, 21 figure
