Public versus private broadcasters’ management
2014
Purpose – The purpose of this paper is to prove the existence of significant differences between private and public corporate credibility antecedents and effects. Design/methodology/approach – Totally, 816 Spanish viewers’ valuations were obtained (408 for the public television network and 408 for four private first generation broadcasters). Results show that some corporate reputation antecedents (perceived quality) and effects (attitudes) are stronger when private broadcasters are considered. Findings – Result show that proposed credibility reputation antecedents and effects are significant and that some differences between private and public entities really do exist. Research limitations…

Life Cycle Assessment of Electricity Generation Scenarios in Italy
2018
Hindering global warming and achieving a more competitive, secure and sustainable energy sector are some of the most relevant goals of the 2030 Framework for climate and energy of the European Union. European countries have to identify and implement strategies for contributing to these ambitious goals. In this context, the authors carried out a scenario analysis on the Sicilian electricity mix in order to estimate the life cycle energy and environmental benefits of the increase of the use of renewable energy technologies for electricity production, and the potential contribution of Sicily in the achievement of the European energy and environmental targets. In detail, the authors identified …
Internal oblique line implants in severe mandibular atrophies
2020
Background Maxillary atrophy may be related to mechanical, inflammatory or systemic factors, being a consequence of a reduction in the amount and quality of available bone. Several surgical techniques have been developed for the restoration of bone volume needed for placing dental implants; guided bone regeneration or three-dimensional reconstructions with autologous bone, inter alia, are techniques described in the literature which demonstrate this, all of which preceded by a proper prosthetic surgical assessment. Even when the majority of authors recommend the use of these techniques prior to placing implants, it has been shown that implants with a smaller diameter and length may be place…
<title>Human cell texture analysis with quincunx spline wavelet transform</title>
1999
Wavelet transforms are efficient tools for texture analysis and classification. Separable techniques are classically used but present several drawbacks. First, diagonal coefficients contain poor information. Second, the other coefficients contain useful information only if the texture is oriented in the vertical and horizontal directions. So an approach of texture analysis by non-separable transform is proposed. An improved interscale resolution is allowed by the quincunx scheme and this analysis leads to only one detail image where no particular orientation is favored. New orthogonal isotropic filters for the decomposition are constructed by applying McClellan transform on one dimension B-…
Performance evaluation of a measurement-based algorithm for distributed admission control in a DiffServ framework
2002
Distributed Admission Control in IP DiffServ environments is an emerging and promising research area. Distributed admission control solutions share the idea that no coordination among network routers (i.e. explicit signaling) is necessary, when the decision whether to admit or reject a new offered flow is pushed to the edge of the IP network. Proposed solutions differ in the degree of complexity required in internal network routers, and result in a different robustness and effectiveness in controlling the accepted traffic. This paper builds on a recently proposed distributed admission control solution, called GRIP (Gauge&Gate Reservation with Independent Probing), designed to integrate the …
New Inhabitants for the Re-use of Historical Territories in South-Eastern Sicily
2021
In spite of the multifaceted criticalities that characterise the Sicilian territory, South-Eastern Sicily appears to be of particular interest due to the active role that distinguishes it from the rest of the Island. The transformation processes taking place in South-Eastern Sicily, in fact, seem to be guided by new perspectives of sustainability, local development and good governance. The mix obtained from the extraordinary amount of tangible and intangible resources, from some favourable socio-cultural circumstances and from the creation of new transportation infrastructures, has contributed to promoting new forms of reuse of the historical building heritage by Italian and overseas invest…
Bone Healing with or without Platelet-Rich Plasma around Four Different Dental Implant Surfaces in Beagle Dogs
2013
Purpose Surface development is one of the major aims in dental implant engineering. Additive application of substances could possibly improve the new bone formation around dental implants. The present study evaluated the bone reaction on four different implant surfaces with or without platelet-rich plasma (PRP). Materials and Methods Four self-tapping titanium screw implants (Branemark MK III [Nobel Biocare, Goteborg, Sweden], Osseotite [3i, Miami, FL, USA], Xive [Densply Friadent, Mannheim, Germany], and Compress [IGfZ eG, Diez, Germany]) with different surfaces were inserted in each hemimandible of 12 female beagle dogs; the implant positions and the application of PRP were randomized. Af…
Updated secondary implant stability data of two dental implant systems. A retrospective cohort study
2017
Background At present, updated secondary implant stability data generated by actual versions of resonance frequency analysis (RFA) and mobility measurement (MM) electronic devices of 2 different implant systems with actual manufactured surfaces seem to lack and/or are incomplete. Material and Methods Secondary implant stability data based on both RFA and MM measurements were collected and analyzed from 44 formerly treated patients (24 f, 20 m) that received either Ankylos Cellplus (Ø3.5mm) (A) (n=36) or Straumann regular neck SLA tissue level (Ø4.1mm) (S) (n=37) implants in posterior positions of both jawbones (total number= 72). These results were interpretated in view of formerly publishe…
