Virtual Clinical and Precision Medicine Tumor Boards-Cloud-Based Platform-Mediated Implementation of Multidisciplinary Reviews Among Oncology Centers…

2021

Background Multidisciplinary tumor boards play a pivotal role in the patient-centered clinical management and in the decision-making process to provide best evidence-based, diagnostic, and therapeutic care to patients with cancer. Among the barriers to achieve an efficient multidisciplinary tumor board, lack of time and geographical distance play a major role. Therefore, the elaboration of an efficient virtual multidisciplinary tumor board (VMTB) is a key point to successfully obtain an oncology team and implement a network among health professionals and institutions. This need is stronger than ever during the COVID-19 pandemic. Objective This paper presents a research protocol for an obse…

“TEACHING REAL NUMBERS IN THE HIGH SCHOOL: AN ONTO-SEMIOTIC APPROACH TO THE INVESTIGATION AND EVALUATION OF THE TEACHERS' DECLARED CHOICES”

The thesis addresses the topics of investigating teachers' declared choices of practices concerning real numbers and the continuum in the high school in Italy, evaluating their didactical suitability and the impact of a deep reflexion about some historical and didactical issues on the teachers' decision-making process. Our research hypothesis was that teachers' choices of teaching sequences concerning real numbers, with particular attention to the representations of real numbers, could be very relevant in order to interpret some of the well-known students' difficulties. After a pilot study in form of a teaching experiment and a literature review concerning students' and teachers' difficulti…

Ontological information system for the selection of technologies for the treatment and disposal of organic waste: engineering and educational aspects

2021

The article proves a problem of information processing in the field of the structuring of information and decision-making in environmental engineering, including education in this field. This article presents the ontology-information model that was used to systematize waste treatment equipment. The article presents the use of an ontological algorithm “Polyhedron” for engineers and teachers. The algorithm consists of integrating ontological solutions from abstract to specific. The proposed model consists of a general ontology of “waste treatment technologies selection”, “waste treatment equipment selection” and “Ontology for the analysis of scientific publications”. Users of the system can i…

Robotic-assisted right colectomy. Official expert recommendations delivered under the aegis of the French Association of Surgery (AFC)

2022

: Twenty-seven experts under the aegis of the French Association of Surgery (AFC) offer this reference system with formalized recommendations concerning the performance of right colectomy by robotic approach (RRC). For RRC, experts suggest patient installation in the so-called "classic" or "suprapubic" setup. For patients undergoing right colectomy for a benign pathology or cancer, RRC provides no significant benefit in terms of intra-operative blood loss, intra-operative complications or conversion rate to laparotomy compared to laparoscopy. At the same time, RRC is associated with significantly longer operating times. Data from the literature are insufficient to define whether the robot f…

The neurochemistry of autism

2020

Autism spectrum disorder (ASD) refers to complex neurobehavioral and neurodevelopmental conditions characterized by impaired social interaction and communication, restricted and repetitive patterns of behavior or interests, and altered sensory processing. Environmental, immunological, genetic, and epigenetic factors are implicated in the pathophysiology of autism and provoke the occurrence of neuroanatomical and neurochemical events relatively early in the development of the central nervous system. Many neurochemical pathways are involved in determining ASD; however, how these complex networks interact and cause the onset of the core symptoms of autism remains unclear. Further studies on ne…

Seismic shakedown design of frames based on a probabilistic approach

2014

The present study concerns the optimal design of elastic perfectly plastic structures subjected to a combination of fixed and seismic loads. In particular, plane frames are considered and suitable measures of the beam element cross sections are chosen as design variables. The optimal design is required to behave in a purely elastic manner when subjected just to the fixed load and to have the capability to eventually shakedown when simultaneously subjected to fixed and seismic loads. Due to the natural uncertainness related to the definition of the seismic load history, a new probabilistic approach is proposed, consisting into two subsequent search steps. At first a suitably chosen large num…

A gradient-based decomposition approach to optimize pressure path and counterpunch action in Y-shaped tube hydroforming operations

2008

International audience; In tube hydroforming, the concurrent actions of pressurized fluid and mechanical feeding allows obtaining tube shapes characterized by complex geometries such as different diameters sections and/or bulged zones. Main process parameters are material feeding history (i.e., the punches velocity history), internal pressure path during the process, and (in T- or Y-shaped tube hydroforming) counterpunch action. What is crucial, in such processes, is the proper design of operative parameters aimed to avoid defects (for instance underfilling or ductile fractures). Actually, the design of tube hydroforming operations is mainly aimed to prevent bursting or buckling occurrence …

La salute organizzativa nei contesti sanitari: Un’esperienza di ricerca-intervento.

2011

ABSTRACT - From a psychosocial perspective that is intended to produce both understanding and change, especially involv-ing social actors in the construction of shared meanings, this paper illustrates the results of the first stage of an action research process focused on organizational health. The study has been carried out within an Italian hospital combining both quantitative and qualitative methods. Specifically, the data were gathered through the administration of Multidimensional Organizational Health Questionnaire (n=782) and focus group interviews whose transcripts were analyzed with the software T-Lab. The analysis of collected data has allowed us to trace the organizational health…

Structural Dynamics and Intentional Governance in Strategic Interorganizational Network Evolution: A Multilevel Approach

2016

This article aims to shed light on the drivers underlying the role and scope of intentional governance of the structural dynamics of whole interorganizational networks. Prior research has distinguished networks that are emergent from networks that are orchestrated. While empirical studies have shown situations in which the role and scope of intentional governance of whole interorganizational networks has changed in time, and there is a growing interest regarding the endogenous drivers of network dynamics, the dimensions that influence intentional governance of network structure dynamics and the way this is carried out remain still to be elucidated. In order to pinpoint these drivers, we le…

Engaged managers are not workaholics: Evidence from a longitudinal personcentered analysis

2013

El objetivo de este estudio longitudinal entre directivos finlandeses ( n = 463) fue doble: en primer lugar investigar la relación entre el engagement (E) y la adicción al trabajo (AT) mediante enfoques centrados en la persona y en la variable y, en segundo lugar, explorar si (y cómo) se relacionan las experiencias de engagement y la adicción al trabajo con el cambio de trabajo durante el período de estudio. El análisis centrado en las variables, basado en modelos de ecuaciones estructurales, mostró que los factores latentes del engagement y la adicción al mismo no correlacionan entre sí, lo que sugiere que son constructos independien- tes. Los análisis centrados en la persona indicaron cua…
