The Italian multiple sclerosis register

2019

The past decade has seen extraordinary increase in worldwide availability of and access to several large multiple sclerosis (MS) databases and registries. MS registries represent powerful tools to provide meaningful information on the burden, natural history, and long-term safety and effectiveness of treatments. Moreover, patients, physicians, industry, and policy makers have an active interest in real-world observational studies based on register data, as they have the potential to answer the questions that are most relevant to daily treatment decision-making. In 2014, the Italian MS Foundation, in collaboration with the Italian MS clinical centers, promoted and funded the creation of the …

Finding Factors Influencing Students’ Preferences to Concept Mapping Tasks: Literature Review

2014

Abstract There is a broad set of concept mapping tasks which can be used by teachers for assessing students’ knowledge structures but there are no known works of research studying their adaptation to students’ individual differences and preferences in relation to different tasks. The paper reports first results of activities which aim to offer a solution of the abovementioned problem. It is based on extensive review of theoretical and empirical studies and focuses on: a) identification of advantages and drawbacks of different concept mapping tasks, and b) finding factors which may affect students’ concept mapping ability.

Was King Arthur a King by Definition?

1988

Current research in knowledge representation distinguishes between descriptional and assertional interpretations of semantic nets. This paper explores theoretical and applicative problems, which arise from that distinction in a historic domain. A prolog implementation of KL-ONE is used as a vehicle to compare the various alternatives available to represent knowledge related to single elements of the domain insertion or not of this knowledge in semantic nets in their descriptional sense. The final section of the paper discusses the problem in relation to the theories concerning the functioning of proper names from a logical and philosophical point of view.

¿Cómo diseñar una secuencia de enseñanza de ciencias con una orientación socioconstructivista?

2009

Abstract This conference aims to show how the results of research in science teaching can be used by teachers in the design and development of a sequence of learning from a socio-constructivist view. Based on the training needs of the teacher to successfully face the challenges of teaching, teachers have to develop four skills in the design of a teaching sequence: the history and epistemology of the concepts and theories taught and, in particular, major problems in its construction; namely the sequencing of objectives and appropriate content to the student's psychological problems, in the form of interest; determine the specific knowledge and skills students should acquire in relation to th…

The ongoing digitalization of educational resources and the use of the internet lead to a steady increase of potentially available learning media. However, many of the media which are used for educational purposes have not been designed specifically for teaching and learning. Usually, linguistic criteria of readability and comprehensibility as well as content-related criteria are used independently to assess and compare the quality of educational media. This also holds true for educational media used in economics. This article aims to improve the analysis of textual learning media used in economic education by drawing on threshold concepts. Threshold concepts are key terms in knowledge acqu…

Nest aggregation and reproductive synchrony promote Lesser Kestrel Falco naumanni seasonal fitness

2013

Several factors promote coloniality by enhancing the fitness of colony members. In birds, spatial proximity among nests, breeder abundance and reproductive synchrony have been proposed as primary factors responsible for enhanced colonial defence and foraging success, which, in turn, enhance reproductive success. Whether these factors function synergistically or antagonistically remains, however, an open question due to the absence of an integrated analysis of their effects on fitness. We studied a large population of the Lesser Kestrel, Falco naumanni, a facultative colonial species, breeding in colonies of different sizes in their typical pseudo-steppe habitat. We quantified both the singu…

Distinguishing between two crus : as easy as picking the right side ? : Effect of expertise on conceptual and perceptual representations of Beaujolai…

2017

Expertise was studied in cognitive psychology in order to understand the psychological mechanisms and the abilities involved in various areas of expertise. In the wine field, the few studies conducted on expertise suggest that the knowledge representation of experts is organized around “prototypes” derived from wines of different colours or grape varieties. The general purpose of this thesis was to address 1) theoretical questions about knowledge representation of wines among experts and novices, and 2) wine industry questions about Beaujolais wine perceptions. To this end, the effect of expertise on knowledge representations of wines was evaluated by comparing the performance of three diff…

2017

L’expertise a été étudiée en psychologie cognitive afin de comprendre les mécanismes psychologiques et les compétences intervenant dans différents domaines d’expertise. Dans le domaine du vin, les quelques études menées suggèrent que les experts organiseraient leurs connaissances autour de « prototypes » de couleur ou de cépage. L’objectif général de cette thèse visait à répondre aux questionnements théoriques concernant les représentations des vins d’experts et de novices, ainsi qu’aux questionnements de la filière concernant les perceptions des vins du Beaujolais. Pour cela, l’effet de l’expertise sur les représentations des vins a été évalué en comparant les performances de trois panels …

Groupware Support for Requirements Management in New Product Development

2005

Large high-technology companies operate in fiercely competitive international markets. To succeed, they need to shorten the cycle time of new product development (NPD) while improving product quality and maintaining or reducing the total resources required. Their abilities to meet these business goals depend on how extensively and effectively they collect, analyze, and utilize requirements in their product development. Creating and sharing such knowledge is complicated partly because the NPD activities of large companies are geographically distributed. Groupware technologies allow knowledge to be created and shared more effectively. Thus, they hold considerable potential as means of meeting…

An information systems design product theory for the class of integrated requirements and release management systems

2010

High-tech companies conducting product development need to collect and analyze requirements effectively, plan and implement releases, and allocate requirements to appropriate releases. Requirements and release management are complicated because development activities typically are scattered across multiple sites, involve multiple partners in different countries, leverage various development methods and tools, and are realized through various organizational arrangements such as release projects in organizations structured around products and permanent release teams in organizations responsible for the long-term development and maintenance of strategic software and hardware assets. Flexible, …
