Impact of the terrestrial reference frame on the determination of the celestial reference frame.
2022
Currently three up-to-date Terrestrial Reference Frames (TRF) are available, the ITRF2014 from IGN, the DTRF2014 from DGFI-TUM, and JTRF2014 from JPL. All use the identical input data of space-geodetic station positions and Earth orientation parameters, but the concept of combining these data is fundamentally different. The IGN approach is based on the combination of technique solutions, while the DGFI is combining the normal equation systems. Both yield in reference epoch coordinates and velocities for a global set of stations. JPL uses a Kalman filter approach, realizing a TRF through weekly time series of geocentric coordinates. As the determination of the CRF is not independent of the T…
The distributions of protein coding genes within chromatin domains in relation to human disease.
2019
Abstract Background Our understanding of the nuclear chromatin structure has increased hugely during the last years mainly as a consequence of the advances in chromatin conformation capture methods like Hi-C. The unprecedented resolution of genome-wide interaction maps shows functional consequences that extend the initial thought of an efficient DNA packaging mechanism: gene regulation, DNA repair, chromosomal translocations and evolutionary rearrangements seem to be only the peak of the iceberg. One key concept emerging from this research is the topologically associating domains (TADs) whose functional role in gene regulation and their association with disease is not fully untangled. Resul…

A Framework of Professional Transferable Competences for System Innovation: Enabling Leadership and Agency for Sustainable Development
2021
System Innovation (SI) is a critical approach in driving individual and collective actions towards sustainable development (SD). This article presents the validation process of the Climate-KIC Professional Competence Framework (CF) for SI. This framework is based on principles of system thinking and the need for human capital to deal with challenges related to long-term sustainability. It comprises twenty competences grouped into five stages that describe contexts where professionals implement transformations: Exploring, Framing, Designing, Implementing and Strengthening. The stages are not linear or strictly sequential because overlapping and loops are frequent in transformational and disr…
Identity and relationship frames in medical leadership communication
2021
PurposeA frame is an interpretive scheme of meanings that guide participants’ interpretations of social interaction and their actions in social situations (Goffman, 1974). By identifying early-career physicians’ identity and relationship frames, this study aims to produce information about socially constructed ways to interpret leadership communication in a medical context.Design/methodology/approachThe data consist of essays written by young physicians (n= 225) during their specialization training and workplace learning period. The analysis was conducted applying constructive grounded theory.FindingsThree identity and relationship frames were identified: the expertise frame, the collegial …
Interpretazione cognitiva, interpretazione decisoria, interpretazione creativa
2013
The article critically reviews Riccardo Guastini’s theory of legal interpretation, as it is now exposed in the recent book Interpretare e argomentare. While broadly sympathetic with Guastini’s jurisprudential project, the author tries to highlight some weaknesses in his conceptual framework – namely, regarding the distinction between “scientific” and “decisional” interpretation, the distinction between interpretation properly understood and creation of new law, and the concept of interpretive creativity
A Novel Fast Volumetric Light Sheet Microscopy
2016
Fast noninvasive three-dimensional (3D) imaging is crucial for the quantitative understanding of highly dynamic biological processes. Over the last decades, several fluorescence microscopy techniques have been developed in order to provide a faster and deeper imaging of thick biological samples [1]. Within this framework, Light Sheet Fluorescence Microscopy (LSFM) has emerged as a powerful imaging tool for 3D imaging of thick samples ranging from single cells to entire animals [2,3].However, to obtain a 3D reconstruction either sample or microscope parts usually need to be moved limiting the acquisition speed and inducing possible interferences in volume recording. To solve this problem, he…
How perceived value drives the use of mobile financial services apps
2019
Mobile information services have revolutionized business models and service delivery methods by facilitating consumer access to information and order placement via mobile apps. In developed markets, mobile banking (m-banking) and mobile payment (m-payment) applications have replaced text-based mobile services. However, extant research has not addressed these mobile financial services apps (MFSAs) adequately from the perspective of consumer behavior. Thus, the present study developed and tested a series of hypotheses related to the antecedents of perceived value of MFSA use; it also examined how such use affects the development of customers’ overall relationships with banks. Our hypotheses w…
Exploring the Shift from Output Measures to Outcome Measures of Service Delivery: Insights from Municipal Research
2021
Prior research shows that reporting on outcome measures increases the probability that local officials will use perform- ance data to inform their decisions. What has been over- looked in the literature is the question of why some local governments continue to focus more on outputs than on out- comes of service delivery, thereby limiting their ability to use performance data for decision-making. The purpose of this art- icle is to identify organizational, individual, and support factors that could increase the probability that local officials in the Apulia Region of Italy when measuring performance, will move beyond the basic measures of output to the more advanced measures of outcome. Base…
Generalized frame operator, lower semiframes, and sequences of translates
2023
Given an arbitrary sequence of elements $\xi =\lbrace \xi _n\rbrace _{n\in \mathbb {N}}$ of a Hilbert space $(\mathcal {H},\langle \cdot ,\cdot \rangle )$, the operator $T_\xi$ is defined as the operator associated to the sesquilinear form $\Omega _\xi (f,g)=\sum _{n\in \mathbb {N}} \langle f , \xi _n\rangle \langle \xi _n , g\rangle$, for $f,g\in \lbrace h\in \mathcal {H}: \sum _{n\in \mathbb {N}}|\langle h , \xi _n\rangle |<^>2<\infty \rbrace$. This operator is in general different from the classical frame operator but possesses some remarkable properties. For instance, $T_\xi$ is always self-adjoint with regard to a particular space, unconditionally defined, and, when xi is a lo…
