An Urbanistic Project Based on General Systems Theory
1991
This paper intends to be an outline of the Urbanistic Development Planning of the Valencian Community in Spain to be performed during the years 1991 to 1993, The following are considered as objectives of the Planning: – Quality of Life improvement, – protection of Nature, – rational management of natural resources, – rational use of land; all based on social demand. The territory and the mechanism of intervention is considered as a system whose elements can be grouped as: – uses of land, – infrastructure, equipment, services, – objectives, – intervention and management. The Planning proposes itself to be: integral, strategic, prospective, programmed, controllable and participative, A simula…
Inventory policies and information sharing in multi-echelon supply chains
2011
The aim of this article is to show how to modify a replenishment rule in relation to the operational information shared by suppliers. More specifically, we present a model of an Automatic Pipeline Variable Inventory and Order-Based Production Control System rule for a multi-echelon supply chain characterised by different increasing levels of shared information. A numerical study is presented to underline the performance differences for three variants of the smoothing order rule in terms of bullwhip reduction, inventory stability and operational and customer responsiveness. Results show how the effectiveness of a smoothing replenishment rule depends on the level of information sharing.
Structure Monitoring with BIM and IoT: The Case Study of a Bridge Beam Model
2022
The diffusion of Building Information Modelling (BIM) as a reference methodology, applied to the world of construction, leads to important changes in the design and the management of big constructions and infrastructures. However, although the BIM approach is necessary for managing the entire life cycle of a construction, today, this methodology is still rarely adopted beyond the design phase. This represents a major flaw because the management of every phase of the life cycle of buildings needs accurate preliminary planning. Certainly, one of the most complex and important phases of the life cycle of a construction is the monitoring phase, which represents a fundamental aspect for the main…
[1,2,3]Triazolo[1,5-a]pyridyl phosphines reflecting the influence of phosphorus lone pair orientation on spectroscopic properties
2010
A series of new triazolopyridine-based phosphines has been prepared. These compounds revealed unexpected spectroscopic patterns. In particular, the NMR spectra are highly dependent on the relative conformational preference of the phosphine substituent at C7. Here, we report on their complete NMR analysis, X-ray structures and DFT calculations that confirm the particular arrangement of the phosphorus lone pair orbital related to the substituent pattern of the chosen phosphine.
The evaluation of urban soils aimed at the sustainability of plants in public and private flowerbeds
2020
The authors report the survey of some flowerbeds located in the city of Palermo with the aim of assessing the sustainability of the plants and the interventions to be implemented, i.e. cutting or transfer of plants, to achieve a sustainable green. In the case in which it is possible to insert other plants in the flowerbeds, it is recommended to elaborate a project using programs that allow to have a preview of the spaces available for the new plants. This work is methodological and is aimed at creating a green that can achieve the functional objectives in relation to the site where it is located (sustainability in all aspects) and at low management costs with no or almost no irrigation prac…
Access to scientific information. A national survey of the Italian Society of Clinical Biochemistry and Laboratory Medicine (SIBioC).
2016
Abstract Background: Digital libraries are typically used for retrieving and accessing articles in academic journals and repositories. Previous studies have been published about the performance of various biomedical research platforms, but no information is available about access preferences. Methods: A six-question survey was designed by the Italian Society of Clinical Biochemistry and Laboratory Medicine (SIBioC) using the platform Google Drive, and made available for 1 month to the members of the society. The information about the survey was published on the website of SIBioC and also disseminated by two sequential newsletters. Results: Overall, 165 replies were collected throughout the …
Normalizing biproportional methods
2002
International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.
Characterization of disease-specific cellular abundance profiles of chronic inflammatory skin conditions from deconvolution of biopsy samples
2019
Background Psoriasis and atopic dermatitis are two inflammatory skin diseases with a high prevalence and a significant burden on the patients. Underlying molecular mechanisms include chronic inflammation and abnormal proliferation. However, the cell types contributing to these molecular mechanisms are much less understood. Recently, deconvolution methodologies have allowed the digital quantification of cell types in bulk tissue based on mRNA expression data from biopsies. Using these methods to study the cellular composition of the skin enables the rapid enumeration of multiple cell types, providing insight into the numerical changes of cell types associated with chronic inflammatory skin c…
Some thoughts about the conceptual / procedural distinction in translation: a key-logging and eye-tracking study of processing effort
2014
This article builds on the conceptual / procedural distinction postulated by Relevance Theory to investigate processing effort in translation task execution. Drawing on relevance-theoretic assumptions, it assumes that instances related to procedural encodings will require more effortful processing not only in relation to the time spent on the task but also in terms of product indicators such as seconds per word and number of micro translation units per word. Drawing on key-logging and eye-tracking data, the article shows that there are statistically significant differences when conceptual and procedural encodings are analysed in selected areas of interest, with instances related to procedur…
Dealing with Tensions in Technology Enabled Healthcare Innovation: Two Cases from the Norwegian Healthcare Sector
2017
In Chapter 5, Grisot, Vassilakopoulou and Aanestad examine patient-focused ICT applications, which extend traditional health information infrastructures and have the potential to transform the relation between patients and doctors, allowing for a more active patient role. However, new design challenges emerge because it is unclear how existing infrastructures can accommodate novel usage areas, and how they should be modified or even substituted. In this chapter, the authors’ research aim is to examine such challenges, framed as ‘design tensions’ in the context of ICT-enabled innovation processes in healthcare. Building on Information Infrastructure theory, the authors examine how such desig…
