Algebras with intermediate growth of the codimensions
2006
AbstractLet F be a field of characteristic zero and let A be an F-algebra. The polynomial identities satisfied by A can be measured through the asymptotic behavior of the sequence of codimensions and the sequence of colengths of A. For finite dimensional algebras we show that the colength sequence of A is polynomially bounded and the codimension sequence cannot have intermediate growth. We then prove that for general nonassociative algebras intermediate growth of the codimensions is allowed. In fact, for any real number 0<β<1, we construct an algebra A whose sequence of codimensions grows like nnβ.
Varieties of Algebras with Superinvolution of Almost Polynomial Growth
2015
Let A be an associative algebra with superinvolution ∗ over a field of characteristic zero and let $c_{n}^{\ast }(A)$ be its sequence of corresponding ∗-codimensions. In case A is finite dimensional, we prove that such sequence is polynomially bounded if and only if the variety generated by A does not contain three explicitly described algebras with superinvolution. As a consequence we find out that no intermediate growth of the ∗-codimensions between polynomial and exponential is allowed.
A privacy enhanced device access protocol for an IoT context
2013
In this paper, we present the case for a device authentication protocol that authenticates a device/service class rather than an individual device. The devices in question are providing services available to the public. The proposed protocol is an online protocol, and it uses a pseudo-random temporary identity scheme to provide user privacy. This allows the Internet-of-Things device to have full assurance of the user, with respect to the request service, while permitting the user to remain anonymous with respect to the device. The user can then enjoy identity and location privacy in addition to untraceability with respect to device access. Copyright © 2013 John Wiley & Sons, Ltd.
Harnessing ICT to develop community and identity: a model for academic departments
2006
Universities have been early adopters of Information and Communication Technologies (ICT). However, does availability imply use? How is ICT being used by academic departments? This article addresses these questions, and discusses the use of ICT to support research, instruction and service, but more specifically, the use of ICT to enhance a sense of identity and community across all members of a department. The authors' observations of university departments across the Atlantic reveal very limited uses of ICT. A democratic web-based academic departmental community model is proposed to assist in the strengthening of departmental identity and community as well as advancing its mission. Concept…
Student teachers' experiences of participating in mixed peer mentoring groups of in-service and pre-service teachers in Finland
2017
This article examines from the student perspective a new Finnish model of teacher development that uses the peer group mentoring (PGM) method for combining pre-service and in-service teacher education. Reflective reports of student teachers (N = 19) who participated in PGM were analyzed using the phenomenographic method. The results show that students' experiences varied from considering the activity as (1) a coffee break or (2) peer-support, to seeing it as (3) identity construction or (4) a way of participating in a professional community. In further development of the model more emphasis should be placed on the integration of theory and practice. peerReviewed
CULTURAL IDENTITY AND CONSERVATION OF INDIGENOUS AND NATIVE DIVERSITY
2014
The economic development of rural areas has rarely followed that of urban centres, with greater evidence of this in developing countries where the outlying communities have remained considerably more remote from the systems of cultural and economic growth. Even if this has had negative repercussions in terms of social equilibrium within the various countries, from a strictly agronomic point of view it has often resulted in the natural conservation of indigenous and native biodiversity. This has been affected by the natural and daily use of local plant extracts both for nutritional purposes and for a variety of other reasons. The exchange of genetic material between one community and another…
BioCultural Landscapes per la rigenerazione innovativa dei territori di montagna
2017
Simplification of agricultural systems, farmland abandonment, uncontrolled urbanization, together with global scale drivers, determine fast and unpredictable phenomena of hydrogeological instability, biodiversity decline and identity loss. Men should hence promote socio-economic resilience and place identity, using biocultural landscapes as a resource. These landscapes are the outcome of the historical relationship between man and nature, resulting from complex interactions between biodiversity (at all levels, including species richness, ecosystem and biotope diversity) and cultural diversity, including material and immaterial aspects (architectural heritage, traditions, customs, local trad…
Innovative Applications and Experiments for the Protection of Archaeological Sites
2020
Nowadays, the protection in situ, the enhancement and the fruition of archaeological sites are issues that are even more relevant, if we take into account the effects caused, in recent decades, by climate change both on the conservation of the most fragile artefacts and on the well-being of visitors. New questions related to the ‘recover of identity’ are raised by the relationships that the protection interventions establish with the environmental context (external) and with the ancient ruins (internal), imposing an interpretation of the project as a union of landscape, morphological, climatic, technical, use and management aspects, or by requiring a holistic and integrated approach, from a…
Form follows function. Bob Noorda e il sistema di identità visiva per il Touring Club Italiano
2011
Quella che vogliamo raccontare in queste pagine è una microstoria del graphic design in Italia, scritta da un olandese che del suo paese d’origine ha mantenuto molto, in primis la formazione, la cultura del progetto, l’accento e lo stile, e del nostro ha assimilato altrettanto, tutti aspetti che hanno contribuito a fare di lui, Bob Noorda, un progettista ad altissimo livello che ha scritto con la sua lunga e importante carriera professionale, parte della storia della disciplina progettuale. Una microstoria che lega il Touring Club Italiano (TCI) al graphic designer che ne ha ridisegnato il marchio, senza che il parlare di ridisegno possa assumere in alcun modo un’accezione riduttiva per il …
Design e Artigianato in Sicilia. Scambio e contaminazione tra forme diverse della progettualità.
2023
While travelling on the fast tracks of the digital world, our age has long understood the importance of promoting cultural heritage. In this context, the intangible heritage that is made up of the baggage of knowledge related to artisanal know-how represents the foundation of the determination of territorial identities. The School of Design of the University of Palermo was among the first to embrace the idea of using design as a tool to safeguard and evolve the skills of craftsmanship: in the words of Anna Maria Fundarò, founder in 1981 of the Industrial Design Institute of Palermo, the identity of Sicilian design is engraved in the DNA of a discipline whose meaning "is linked to our local …
