Synchronization of hidden chaotic attractors on the example of radiophysical oscillators

2017

In the present paper we consider the problem of synchronization of hidden and self-excited attractors in the context of application to a system of secure communication. The system of two coupled Chua models was studied. Complete synchronization was observed as for self-excited, as hidden attractors. Beside it for hidden attractors some special type of dynamic was revealed.

Sir Thomas More's Utopia : An overlooked economic classic

2019

Sir Thomas More's Utopia, published in 1516, is a classic work of how to organise a society based on common property. With a unique mix of common property, institutions and sound economic insights, we argue that More built a framework for a society that could be viable in the long run. While the conditions that make Utopia work are quite restrictive, it does provide a sketch of a society where common property may not stifle long‐term development, but is associated with productive workers and people content with their lives.

Thou shalt not write about... : a study of taboo content in Finnish EFL textbooks for upper secondary school

2012

Tabu on käsitteenä monimuotoinen ja vaikeasti määriteltävä, johtuen sekä niiden jatkuvasta muuttumisesta, valtavasta määrästä että niiden osittaisesta kulttuurisidonnaisuudesta. Tabuja ja tabukielen esiintymistä oppimateriaaleissa on tutkittu erittäin vähän, tutkimuksen keskittyessä lähinnä määrittelemään, mitkä aiheet ovat teoriassa tabuja maailmanlaajuisissa englannin kielen oppimateriaaleissa. Myös mahdolliset riskit, jotka liittyvät tabujen sisällyttämiseen oppimateriaaleihin ovat olleet tutkimuksen kohteena. Varsinainen empiirinen tutkimus tabujen esiintyvyydestä oppikirjoissa on kuitenkin jäänyt vähemmälle huomiolle. Tutkielmamme keskittyikin juuri tähän tutkimattomaan alueeseen. Tutk…

Uudelleenistutuksien ongelmat : poikasten pedonvälttämiskäyttäytyminen kahdella tarhatulla peltopyyn (Perdix perdix) alalajilla

2015

Ihmistoiminta on joko suoraan tai välillisesti aiheuttanut useiden lajien populaatioiden taantumisen ja jopa sukupuuton. Eläinten tarhauksen ja kasvatustoiminnan avulla pyritään säilyttämään lajin kanta elinvoimaisena vapauttamalla tarhassa kasvatettuja yksilöitä luontoon. Tarhaolosuhteet voivat kuitenkin poiketa paljon luonnonoloista, jolloin valintapaineet ovat erilaiset kuin luonnossa. Jos tarhaus jatkuu useita sukupolvia, yksilöt sopeutuvat tarhaolosuhteisiin, jolloin ne voivat poiketa villeistä alkuperäisyksilöistä. Suomessa peltopyy (Perdix perdix) on yksi maatalousympäristön muutoksen seurauksena taantunut laji. Maa- ja metsätalousministeriö on laatinut Suomen peltopyykannan hoitosuu…

The effects of different combinations of fixed and moving bed bioreactors on rainbow trout (Oncorhynchus mykiss) growth and health, water quality and…

2019

The effect of bioreactor design on nitrification efficiency has been well studied, but less is known about the overall impacts on water quality. Besides nitrification, submerged fixed bed bioreactors (FBBR) trap fine solid particles, whereas moving bed bioreactors (MBBR) grind solids, possibly increasing solids and particle accumulation in the system. In this experiment, the effects of different combinations of fixed bed and moving bed bioreactors on water quality, solids removal, particle size distribution, fish health based on histopathological changes and nitrification efficiency were studied in laboratory scale recirculating aquaculture systems (RAS) with rainbow trout (Oncorhynchus myk…

The identity of the tropical African

2016

Abstract Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both t…

Students’ agency profiles in relation to student-perceived teaching practices in university courses

2020

This study addresses the gap in our understanding of the role of pedagogy in agency construction among higher education students. In the present study, profiles of students’ agency experiences were identified and analysed with respect to the students’ perceptions of teaching practices in their courses (i.e., student-centred learning activities, forms of instruction, and student-teacher roles). The Agency of University Students (AUS) Scale (Jääskelä et al., 2017) was used to assess the students’ experiences of their personal, relational, and participatory resources of agency. Agency profiles were found to be associated with students’ perceptions of teaching practices in the courses. The find…

Tipologie di ricerca didattica in Italia (2016-2018)

2020

In Italia, nel triennio 2016-2018, si è fatta ricerca didattica sul processo di insegnamento- apprendimento in tre modi: l’analisi fenomenologica e l’osservazione della dimensione quantitativa della realtà educativa; la costruzione di categorie interpretative del collegamento delle azioni dei docenti con i cambiamenti osservati nei discenti; la formulazione di principi e orientamenti per la pratica didattica. I temi delle ricerche didattiche svolte nel periodo sono raggruppabili in quattordici aree: la didattica universitaria, la didattica inclusiva, la didattica interculturale, la didattica orientativa, la didattica metacognitiva, la raccolta e l’analisi di pratiche didattiche, le nuove te…
