THE IMPLEMENTATION OF MASSIVE OPEN ONLINE COURSES FOR TRAINING FUTURE ENGINEERS IN HIGHER EDUCATION
2020
This paper investigates the features of the implementation, conduct, analysis and prospects for the use of massive, open online courses. The article deals with the main advantages and disadvantages of massive open online courses, presents a comparative analysis of research into implementation of massive, open online courses. The article outlines the basic course requirements. It contains an analysis of the current state of such courses in higher educational institutions. The article presents a number of recommendations for the development of the education system towards democratization of higher education
Affordable housing in western Europe. Forms, typologies and paradigms through a genealogical approach. 1852-2019
2022
The essay concerns housing as a major tool for urban regeneration and for experiment in architecture. Within this larger research scope, this paper aims to explore some issues linked to contemporary European processes of urban regeneration through housing in a genealogical approach. At first, will be evocated the initial European typological evolution of affordable housing, outlining the early development of the urban working-class housing estate in Paris, and London . The discussion of the two main paradigms elaborated at that foundational stage will focuses the appearance of the open block for mixed-use housing at the very end of the 19th century. Then, the article will shortly engage wit…
Selective opening of nanoscopic capped mesoporous inorganic materials with nerve agent simulants; an application to design chromo-fluorogenic probes.
2011
A hybrid nanoscopic capped mesoporous material, that is selectively opened in the presence of nerve agent simulants, has been prepared and used as a probe for the chromo-fluorogenic detection of these chemicals. © 2011 The Royal Society of Chemistry.
Molte Palermo. Temi
2019
Nel tema delle incompiute idee di città possibili si riconoscerà il paradigma connotativo dello stesso divenire di Palermo, lungo un percorso millenario di processi di trasformazione nessuno dei quali portato a compimento, in virtù di quel valore distintivo di exemplum che non necessita di ulteriori e conclusive dimostrazioni. Il corso della storia, del resto, ha imposto a Palermo il ciclico riproporsi di destini interrotti. Tale si rilevò l’invenzione della città capitale, quella della “quadratura geometrica e della croce di strade” sovrimpressa a quella archetipica e fondativa della Pan-ormos scambiatrice. E l’incompiutezza sarà il tratto distintivo della città dei rettifili stradali otto…
The effect of early or late R&D inbound alliance on innovation
2016
In the research-and-development (R&D) supply chain, firms can agree an inbound alliance at different times along the R&D process; this decision affects the supplier's effort and the innovation that firms achieve at the end of the agreement. Because the supplier's effort is not entirely observable, firms cannot enforce effort contractually. Early contracts demand greater effort and offer risk-sharing opportunities; in late contracts suppliers have a stronger ex-ante bargaining-power position because of the shorter (and less risky) contract length and the experience suppliers already have. This study argues that later inbound alliances allow a higher innovation value when both partner…
Ethics, resource rent, environment and petroleum policy: the case of a small open economy
2021
This paper contributes to the understanding of how the environment, ethics, values, and historical contingencies shape public policy. It explains the accomplishment of petroleum resource management in the small open economy of Norway. The study is conducted by mapping policy decisions and the arguments behind them regarding environmental and ethical issues. This is done by studying available governmental and parliamentary papers along with statements from politicians and central governmental officials. The paper also seeks to illuminate some of the decisions by quantitative measures. The paper firstly describes a model of Ricardian resource rent. Secondly, it investigates the set of values …
Open innovation and firms performance: state of the art and empirical evidences from the bio-pharmaceutical industry
2016
The research presented in this paper explores the effect of inbound, outbound and coupled open innovation practices on firms' performances in the biopharmaceutical industry. Specifically, although existing researches on open innovation effectiveness have separately investigated the effect of open innovation practices on innovation and financial performance, this study evaluates the concurrent effect of these practices on both such performance dimensions in a single framework. We state the importance for a manager to explore concurrently the influence of specific open innovation practices both on innovation and economic-financial performance. We empirically test our framework on a sample of …
From Benzofurans to Indoles: Palladium-Catalyzed Reductive Ring-Opening and Closure via β-Phenoxide Elimination
2018
International audience; Benzofurans can undergo ring-opening by a palladium-catalyzed process resulting in C−O bond breaking. Benzofuran-tethered 2-iodoanilines give synthetically interesting 2-(3-indolylmethyl)phenols in an overall reductive process. Mechanistic studies suggest that this unusual reaction proceeds by carbopalladation of benzofuran giving a 3-palladated 2,3-dihydrobenzofuran intermediate, which then fragments by an uncommon trans-elimination of the phenoxide group β to the metal. In this transformation, N,N-diisopropylethylamine (DIPEA) acts as a base and as a reducing agent: it regenerates palladium(0) from palladium(II), thus allowing catalytic turnover.
Empirical Equations for the Direct Definition of Stress–Strain Laws for Fiber-Section-Based Macromodeling of Infilled Frames
2018
Equivalent strut macromodels are largely used to model the influence of infill walls in frame structures due to their simplicity and effectiveness from a computational point of view. Despite these advantages, which are fundamental to carrying out seismic simulation of complex structures, equivalent struts are phenomenological models and therefore have to conventionally account for the influence of really large amounts of geometrical and mechanical variables with a relatively simple inelastic response. Mechanical approaches, generally used to evaluate the force-displacement curve of a strut, are based on hypothesizing the damage mechanism that will occur for an infill-frame system subject to…
Macroelement Model for the Progressive-Collapse Analysis of Infilled Frames
2021
A new multistrut macromodel for the analysis of the progressive-collapse response of infilled reinforced concrete (RC) frames is presented in this paper. The model consists of three struts: two outer infinitely rigid and resistant struts and one inner fiber-section strut. The inclination of the struts as well as the stress-strain response are modulated by two parameters that are obtained by means of analytical correlations provided in the paper. The latter link the geometric and mechanical properties of an infilled frame to the geometric configuration and mechanical response of the equivalent strut model. This confers the model the capability to adapt to consider different collapse configur…
