    No full text
    The primary purpose of this study is to use the principles of service science as a foundation approach to provide a path for innovation and transformation service business models (SBMs) through the power of cloud technology within the service ecosystem. In addition, this research, contributes to improve the understanding for the business dynamics behind this transformation in such a way that to explain the processes for GDL to transition to SDL business innovation models. Moreover, this paper seeks to answer the question that how cloud to create value in the context of SBMs within the service ecosystem? This paper is one of the first attempts to integrate these disciplines, so that it offers an original contribution by propose the novel trend in the form of a path with 5 steps for SBMs innovation and transformation and also co-create value. This research has a qualitative approach to seek to answer the research questions that has been adopted based on Kitchenham et al. (2009) seven steps guidelines for conducting a systematic literature review. This paper is the first systematic reviews on the business models that is supported through cloud technology so that conducted using the 45 research articles shortlisted were discussed and analyzed and finally on that basis, a path with 5 steps is provided to answer the research questions. Moreover, this study provides insights to SMEs, ICT vendors, service providers and government agencies to align the business models with cloud services for the most benefits. It also to act as a guide for practitioners to seek and apply such models in their business in order to produce smart solutions that can provision even smarter services

    A Regional Adaptive and Assimilative Three-Dimensional Ionospheric Model

    No full text
    An adaptive three-dimensional (3D) regional ionospheric model is proposed. It is able to ingest real-time data from different ionosondes, providing the ionospheric bottom side plasma frequency fp over the Italian area. The model is built using as basis empirical values over the considered region of a set of ionospheric parameters Pibase, to some of which has been assigned an increment Pi. Then, the values of the ionospheric parameters actually observed at a given time in a given site will be Pi= Pibase+Pi. These Pi values are used as input of an electron density N(h) profiler. The latter is derived from the Advanced Ionospheric Profiler (AIP), which is the software used by Autoscala as a part of the process of automatic inversion on the ionogram trace. The 3D-model ingests ionosonde data by minimizing the root-mean-square deviation between the observed and modeled values of fp(h) obtained from the N(h) associated ones, at the points where the observations are available. The Pi values are obtained through the minimization procedure. The 3D-model is tested adapting it with data collected at the ionospheric stations of Rome (41.8 N, 12.5 E) and Gibilmanna (37.9 N, 14.0 E) and using data from the ionospheric station of San Vito dei Normanni (40.6 N, 18.0 E) for comparison. The software developed is able to produce maps of critical frequencies foF2 and foF1 and of fp at fixed altitude, and transverse and longitudinal sections of the bottomside ionosphere, in scale of colors. fp(h) profiles of and associated simulated ionograms are easily producible for each geographic location of the Italian region. Values of fp within the considered volume can be also provided

    Una figura ancora poco decifrabile del Cinquecento religioso italiano. Vecchie e nuove questioni su Pomponio Algieri

    No full text
    This essay presents the unique and mysterious story of Pomponio Algieri, born in Nola, student of the University of Padua; he was persecuted for heresy and transferred from Venice to Rome, where he was executed in August 1556 under the intransigent Pope Paul IV Carafa. The paper takes its cue from the recent volume written by Umberto Vincenti, who tried to sum up Algieri’s story by exploiting the scientific literature and the available sources. The author reviews old and recent historiography which has focused on Pomponio Algieri and questions the “uniqueness” of his case, also reflecting on the possibilities of historical research to shed light on his religious and cultural background and on his uncommon fortitude in the face of a horrible death

    Cuddling as a Form of Social Touch and Its Role in Early Cognitive Development

    No full text
    Children’s understanding that others’ mental states influence their actions develops rapidly during early childhood (Sabbagh & Bowman, 2018). This ability, known as theory of mind (ToM), is linked to the social brain, a network of neural regions that become active when humans interpret and respond to their social environment (Brauer et al., 2017). As these parts of the brain develop, so too do young children’s ToM skills (Sabbagh et al., 2009). Yet, little is known about what influences healthy development of these regions. Although many environmental factors may have importance, one that is particularly intriguing is affectionate contact or “social touch.” Social touch is a context-dependent form of affective touch (Cascio et al., 2018). It stimulates C-tactile afferents, unmyelinated fibers on hairy skin that respond to slow affective touch (e.g., patting or stroking) and has been linked to healthy brain development in infants and young children (Cascio et al., 2018). Recent research has shown that social touch is associated with increased activities in neural regions linked to the social brain (Croy et al., 2021; Gothard & Fuglevand, 2021). These findings suggest that a key factor pacing children’s ToM development is their exposure to social touch. Previous research has observed cuddling, a form of affective touch, to be associated with children’s improved ToM performance. However, it is unclear whether these effects are linked to neural mechanisms involving ToM. Using electroencephalogram (EEG), this study investigates whether cuddling with a parent affects activity in regions of the social brain in 3-to-5-year-old children. Over the summer, twelve participants completed a pilot study. Participants were randomly assigned to cuddle or no-cuddle conditions while resting-state EEG was recorded before and after a storybook task. Children then completed games assessing ToM. Data collection will begin in the fall to further examine cuddling’s effects on children’s cognitive development.   References Brauer, J., Xiao, Y., Poulain, T., Friederici, A. D., & Schirmer, A.

    Color Stability of Resin Cements after Water Aging

    No full text
    The color stability of resin cements plays a key role in the achievement of esthetically-pleasant restorations. Resin luting materials can be mainly divided into two main classes: adhesive (relying on previous application of adhesive systems) or self-adhesive (also known as one-step cements). The different chemical compositions determine their physio-mechanical characteristics which, in turns, influence their color stability. To evaluate the color variations of different dual-cured resin cements after water aging, 80 disc-shaped specimens (15 mm in diameter and 1.2 mm thick) were obtained from the following resin cements (n = 10): (1) Maxcem Elite Universal, MCU (Kerr); (2) RelyX Universal, RXU (3M); (3) Calibra Ceram, CAL (Dentsply); (4) Multilink, MUL (Ivoclar-Vivadent); (5) Panavia V5, PAN (Kuraray); (6) Calibra Universal, CUN (Dentsply); (7) SpeedCEM Plus, SCP (Ivoclar); and (8) Panavia SA, PSA (Kuraray). After light-polymerization, the specimens were measured with a spectrophotometer and CIELab* values were recorded. The specimens were then placed in a digitally controlled thermostatic water bath at 60° for 30 days and afterwards the color measurements were repeated. Color differences were calculated for each specimen before and after water-aging procedures with ΔEab formula and the data were statistically analyzed (p < 0.05). The type of cement statistically influenced the ΔEab (p < 0.05), with MCU showing the lowest color variations (4.3 ± 0.7) whereas RXU and PSA the highest (16.9 ± 1.6 and 16.8 ± 1.2, respectively). No differences were observed between CAL, CUN and SCP (p = 0.05). Color stability is related to the chemical composition of the resinous luting materials, thus material dependent
