Tool use in mathematics: A framework

2015

International audience; In the course of research into the interpretation of tools in the didactics of mathematics I found both voids and conflicts. This paper presents the results of my research and a resultant statement on tool use in mathematics education. The statement incorporates constructs from several theoretical frameworks and I consider the consistency of my statement on tool use with regard to activity theory.

East meets west in the 6th millennium: Mesolithic osseous tools and art from Sise on the Latvian seaboard

2021

A collection of 141 bone and antler tools and debitage pieces recovered from the River Užava at the village of Sise constitutes the largest Mesolithic osseous assemblage in western Latvia. Radiocarbon dating of 12 pieces suggests that most of this collection dates from the 6th millennium calBC. We present a general analysis, highlighting typical and unique tool forms, ornamented and sculpted pieces, and assess the corpus in a wider geographical context. Predominant in this rich and diverse collection are heavy duty antler tools: various forms of adzes, axes and hammers as well as sleeves, made either from shed antler or antler of hunted animals. They include two pieces classifiable as T-axe…

Klases kultūras transformācijas Latvijā fotogrāfiju un atmiņu avotos (1964–2004)

2015

„Klases kultūra” ir jauns jēdziens pedagoģijas vēstures pētniecībā. Tās elementu izpēte ar dažādu vēstures avotu palīdzību sniedz ieskatu skolas realitātē noteiktos vēstures posmos un palīdz izprast un interpretēt cilvēku individuālo pieredzi, kas saistās ar skolas dzīvi, kurā veidojas cilvēka personība, sociālie kontakti un nostiprinās garīgā un emocionālā attīstība. Raksts iepazīstina ar klases kultūras jēdziena teorētiskajiem aspektiem, kā arī, izmantojot vēstures avotu – fotogrāfiju un interviju – analīzi, tiek rekonstruēta klases kultūras tranformācija Latvijā no autoritārā režīma Padomju Savienības laikā uz demokrātisko iekārtu postpadomju Latvijā.

The Genre System Lens on E-Democracy

2008

Published version of an article published in Scandinavian Journal of Information Systems, 20 (2), 51-82. Also available from the publisher at: http://aisel.aisnet.org/sjis/vol20/iss2/3 E-Democracy aims at enhancing citizen involvement in societal communication and decision making. However, the very ideals of democracy vary while reports of e-democracy in use have often left them undiscussed. Moreover, theoretical works on the potential of information technology (IT) for democratization have often viewed IT as a “black box”, and assumed that technology should create an impact as such. Hence, there is a dearth of research on the interplay between models of e-democracy and actual IT artefacts …

Extending the Limits of Nature. Political Animals, Artefacts, and Social Institutions

2020

This essay discusses how medieval authors from the thirteenth and fourteenth centuries dealt with a philosophical problem that social institutions pose for the Aristotelian dichotomy between natural and artificial entities. It is argued that marriage, political community, and language provided a particular challenge for the conception that things which are designed by human beings are artefacts. Medieval philosophers based their arguments for the naturalness of social institutions on the anthropological view that human beings are political animals by nature, but this strategy required rethinking the borderline between nature and art. The limits of nature were extended, as social institution…

Artefacts in CBCT: a review

2011

Artefacts are common in today's cone beam CT (CBCT). They are induced by discrepancies between the mathematical modelling and the actual physical imaging process. Since artefacts may interfere with the diagnostic process performed on CBCT data sets, every user should be aware of their presence. This article aims to discuss the most prominent artefacts identified in the scientific literature and review the existing knowledge on these artefacts. We also briefly review the basic three-dimensional (3D) reconstruction concept applied by today's CBCT scanners, as all artefacts are more or less directly related to it.

Un nouveau protocole d’analyse des grands ensembles de mobiliers métalliques sur la base du NMI : l’exemple du sanctuaire laténien de La Villeneuve-a…

2007

This article aims to show the potential of a new method of studying assemblages of metallic artefacts, based on the counting of the minimum number of individuals represented. After describing the method, it is applied to the artefacts from the sanctuary at La Villeneuve-au-Chatelot (Aube).

Suomalaisuuden ja toiseuden rajamailla : eksotisointi Gallen-Kallelan Museon Afrikka-kokoelman näyttelyhistoriassa

2020

Museoilla on ollut historiallisesti keskeinen rooli kansallisuuden ja kansallisen kuvaston tuottajina ja kulttuuriperinnön ylläpitäjinä. Osana kansallisen identiteetin rakentamisprojektia museot ovat osallistuneet myös eksotisoivan kuvaston ja toiseuden tuottamiseen ja toiminnallaan vahvistaneet kolonialistisia erontekoja. Tässä artikkelissa otamme erityiseen tarkasteluun Gallen-Kallela Museon Afrikka-kokoelman näyttelyhistorian ja pohdimme, miten museo on kokoelmaa esittäessään osallistunut kolonialistisen kuvaston tuottamiseen ja uudelleen tulkitsemiseen. Tutkimuksessa esiin nostamamme näyttelyt jakautuvat neljälle vuosikymmenelle (vuosille 1972, 1987, 1993, 2003). Aineistonamme on kirjal…
