Beyond CLIL: Fostering Student and Teacher Engagement for Personal Growth and Deeper Learning
2018
In its first iteration, Pluriliteracies Teaching for Learning’s primary focus rests on the relationship between the cognitive and the linguistic dimension of learning. The model emphasizes the need for learners to actively make connections between those two dimensions and identifies the processes of knowledge construction and knowledge sharing as the main drivers of deeper learning. It demonstrates how progression for deeper learning can be conceptualized to promote the development of subject specific literacies. Following recent research which clearly indicates that deeper learning processes depend on and are affected by learner variables such as well-being, self-efficacy, engagement, mast…
A New Structural Motif for an Enantiomerically Pure Metallosupramolecular Pd4L8Aggregate by Anion Templating
2014
An enantiomerically pure BINOL-based bis(3-pyridyl) ligand 1 assembles into a homochiral [Pd4(1)8] complex upon coordination to tetravalent PdII ions. The formation of this aggregate is templated by two tetrafluoroborate counterions that are encapsulated in two peripheral cavities. The resulting structure is a new structural motif for this kind of metallosupramolecular assemblies that arranges the palladium ions in a distorted tetrahedral fashion and forces ligand 1 to adopt two different conformations. Both phenomena are unique and cause an overall three-dimensional structure that has another confined, chiral, and hydrophilic central cavity.
The spatiotemporal dimension of doctoral education : a way forward
2020
For an individual doctoral student, doctoral education happens in multiple spaces across a considerable amount of time. However, the existing literature and conceptualisations of doctoral education do not adequately address the spatiotemporal dimension related to it. By using the concept of scales, this article examines how the social action of doing doctoral studies is affected by space and time. As a mode of inquiry, I use nexus analysis, which allows the analyst to spotlight issues that routinely go unnoticed by scholars, policy-makers but also doctoral students themselves. Based on the analysis, I argue that to theorise doctoral education further, its spatiotemporal dimension has to be …
The Low Dimensionality of Development
2020
AbstractThe World Bank routinely publishes over 1500 “World Development Indicators” to track the socioeconomic development at the country level. A range of indices has been proposed to interpret this information. For instance, the “Human Development Index” was designed to specifically capture development in terms of life expectancy, education, and standard of living. However, the general question which independent dimensions are essential to capture all aspects of development still remains open. Using a nonlinear dimensionality reduction approach we aim to extract the core dimensions of development in a highly efficient way. We find that more than 90% of variance in the WDIs can be represen…
Modeling of female human body shapes for apparel design based on cross mean sets
2014
This paper is concerned with a method to build prototypes of human bodies that can be used for apparel design. One of the most important issues in the apparel development process is to define a sizing system to provide a good fitting for the majority of the population. Since anthropometric measures do not present the same linear growth with size in each dimension, it is very important to find a prototype that represents as accurately as possible each class in the sizing system. In this paper we propose a method based on the concept of random compact mean set to define prototypes in apparel design. From a cloud of 3D points obtained with a 3D scanner a solid that represents the human body is…
EMERGING PROPERTIES IN POPULATION DYNAMICS WITH DIFFERENT TIME SCALES
1995
The aim of this work is to show that at the population level, emerging properties may occur as a result of the coupling between the fast micro-dynamics and the slow macrodynamics. We studied a prey-predator system with different time scales in a heterogeneous environment. A fast time scale is associated to the migration process on spatial patches and a slow time scale is associated to the growth and the interactions between the species. Preys go on the spatial patches on which some resources are located and can be caught by the predators on them. The efficiency of the predators to catch preys is patch-dependent. Preys can be more easily caught on some spatial patches than others. Perturbat…
The Level of Mortality in Insured Populations
2018
In the actuarial field, life tables are used in reserving and pricing processes. They are commonly built from aggregate data and incorporate margins as a prudent measure to ensure the insurance company’s viability. Solvency II requires insurance companies to calculate technical provisions using best-estimate assumptions for future experience (mortality, expenses, lapses, etc) to separate (i) the risk-free component from (ii) adverse deviation of claims. Nowadays, however, the methods used by insurance companies (in most countries, included Spain) do not guarantee that these components can be separated. Many companies build their own tables from general insured population life tables, assumi…
Bounded Rationality for “Just In Time” Education
2011
Abstract If you cannot get answers keep putting questions The paper has three targets: a) Taken per se , it advances the research presented in a series of seven papers about education in a post-industrial (i.e., service-oriented) society broadening the scope from engineering to any kind of education reachable through reachable through permanent endeavour. b) Regarded as part of a “EU 2020 research cluster” with the aim to pro pose affordable approaches to education for sustainable development, the paper reveals bounded rationality (BR) as common denominator of, mechanism for, and connection between the two facets of permanent education: e- teaching and e- learning , the research aiming to m…
E-tutoring nella didattica telematica. Pratiche di modellamento.
2021
Il lavoro si propone di delineare quali evoluzioni la figura dell'e-tutor stia attraversando nel contesto della didattica telematica alla luce dei cambiamenti che i media digitali e sociali introducono (Rivoltella, 2017; Ferrari, 2019). Resta fondamentale la dimensione comunicativa su cui tale ruolo si basa (Rivoltella, 2006), che evidenzia la necessità di competenze di moderazione online, allestimento di gestione dei gruppi e animazione di online communities.All'e-tutor, in particolare, è richiesta consapevolezza sull'attività di modellamento che svolge nei confronti dei corsisti attraverso le sue attività comunicative e didattiche (interattive e…
deaR-Shiny: An Interactive Web App for Data Envelopment Analysis
2021
In this paper, we describe an interactive web application (deaR-shiny) to measure efficiency and productivity using data envelopment analysis (DEA). deaR-shiny aims to fill the gap that currently exists in the availability of online DEA software offering practitioners and researchers free access to a very wide variety of DEA models (both conventional and fuzzy models). We illustrate how to use the web app by replicating the main results obtained by Carlucci, Cirà and Coccorese in 2018, who investigate the efficiency and economic sustainability of Italian regional airport by using two conventional DEA models, and the results given by Kao and Liu in their papers published in 2000 and 2003, wh…
