Daugavet- and delta-points in Banach spaces with unconditional bases

2020

We study the existence of Daugavet- and delta-points in the unit sphere of Banach spaces with a 1 1 -unconditional basis. A norm one element x x in a Banach space is a Daugavet-point (resp. delta-point) if every element in the unit ball (resp. x x itself) is in the closed convex hull of unit ball elements that are almost at distance 2 2 from x x . A Banach space has the Daugavet property (resp. diametral local diameter two property) if and only if every norm one element is a Daugavet-point (resp. delta-point). It is well-known that a Banach space with the Daugavet property does not have an unconditional basis. Similarly spaces with the diametral local diameter two property do not have an un…

Robust coordinated control algorithm for multiple marine vessels with external disturbances

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/597195 Open Access The problem of coordinated control for multiple marine vessels in the presence of external disturbances is considered in this paper. A robust coordinated control algorithm is proposed for multiple marine vessels. The proposed robust coordinated control algorithm is divided into two parts. The first part develops an extended state observer to estimate the disturbances of marine vessels. The second part presents a robust coordinated control algorithm based on the output of the extended state observer. Furthermore, the rob…

New delay-dependent stability conditions for time-varying delay systems

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/360924 Open Access This paper addresses the delay-dependent stability for systems with time-varying delay. First, by taking multi-integral terms into consideration, new Lyapunov-Krasovskii functional is defined. Second, in order to reduce the computational complexity of the main results, reciprocally convex approach and some special transformations are introduced, and new delay-dependent stability criteria are proposed, which are less conservative and have less decision variables than some previous results. Finally, two well-known example…

Developing a new approach to managing and mediating conflicts

2017

Generally speaking, words can be elusive and they need to be carefully selected when conveying messages, ideas and proposals between parties. This is all the more evident in mediation process as language has to be neutral and mediators should avoid expressions directing parties. In this regard, recent theoretical developments in postmodern social theory and the social constructionist movement in the social sciences and humanities have provided the field of alternative dispute resolution with a new approach to managing and mediating conflicts. These developments are organized around the ‘narrative approach’ which helps us to see how the language we use to describe and understand our conflict…

Negotiating the Terminological Borders of ‘Language Mediation’ in English and Italian. A Discussion on the Repercussions of Terminology on the Practi…

2015

Linguistic and cultural mediation has been playing an increasingly important role in contemporary society as a result of the intensification of international exchanges and migration flows; however, the definitions that have been given of it are still rather vague and inconsistent. In some cases linguistic and cultural mediation is seen as a broad superordinate category, comprising a range of different interlinguistic and intercultural activities serving the purpose of facilitating communication across languages, cultures and societies in various areas of civil society: industry, business, trade, law, literature, academia, institutions, public services, etc. In other cases, instead, the defi…

Mathematics teaching development: Learning from developmental research in Norway

2014

Published version of an article in the journal: ZDM - International Journal on Mathematics Education. Also available from the publisher at: http://dx.doi.org/10.1007/s11858-013-0567-6 This paper is a product of mathematics teaching developmental research projects based on establishing communities of inquiry comprising schoolteachers working at all grades and university-based teacher educator/researchers (didacticians). The projects are established on the principle that teachers taking an inquiry stance in their practice can assert their agency to develop their teaching to enable improved learning experiences for their students. The educational context and the societal pressure to develop ma…

Wydatki gmin na usługi opiekuńcze a zmiany demograficzne w Polsce

Local governments as the smallest units of territorial self‑government in Poland are responsible for providing care services. The growing number of the elderly can influence the expenditures level connected with ensuring proper care for them, and it may constitute a growing problem for local government, especially for districts with a lower level of socio‑economic development. In recent years, a quite high increase in benefits amount due to care services and specialist care services has been observed. Therefore, a question arises whether a significant dependence can be observed between the share of the elderly in the population and the degree of local governments’ financial burden due to pr…
