On-Orbit Degradation of Solar Instruments

2013

International audience; We present the lessons learned about the degradation observed in several space solar missions, based on contributions at the Workshop about On-Orbit Degradation of Solar and Space Weather Instruments that took place at the Solar Terrestrial Centre of Excellence (Royal Observatory of Belgium) in Brussels on 3 May 2012. The aim of this workshop was to open discussions related to the degradation observed in Sun-observing instruments exposed to the effects of the space environment. This article summarizes the various lessons learned and offers recommendations to reduce or correct expected degradation with the goal of increasing the useful lifespan of future and ongoing s…

Sosiaalityön ammattilaisten tyypilliset työurapolut ja ura-ankkurit

2012

Tutkimuksen tavoitteena oli selvittää, minkälaisia ovat sosiaalityön ammattilaisten tyypilliset työurapolut ja miten erilaiset polut eroavat toisistaan urakehitykseen vaikuttavien ura-ankkureiden suhteen. Ura-ankkurit kuvaavat itse havaittuja kykyjä, motiiveja ja arvoja, jotka vaikuttavat työelämässä toimimiseen. Työurapolun etenemistä hahmotettiin erilaisten horison-taalisten ja vertikaalisten siirtymien kautta. Tutkimus toteutettiin mixed methods -lähestymistapaa hyödyntäen. Siinä yhdistetään laadulli-sen ja määrällisen tutkimuksen elementtejä monipuolisemman kuvan saamiseksi aiheesta. Tässä tutkimuksessa kvalitatiivinen toimintahistoria-kysymys liitettiin kvantitatiiviseen kyse-lylomakke…

To embody or not to embody: A sound design dilemma

2019

Designing with sound is about constructing appropriate sound representations of a concept, from the early ideas to the final product. A survey research on embodied sound sketching is presented, and the problems of early representation in sound design are discussed by analysing the questionnaire results of three workshops on vocal sketching.

Hierarchies of knowledge, incommensurabilities and silences in South African ECD policy: Whose knowledge counts?

2017

AbstractPolicy for young children in South Africa is now receiving high-level government support through the ANC’s renewed commitment to redress poverty and inequity and creating ‘a better life for all’ as promised before the 1994 election. In this article, I explore the power relations, knowledge hierarchies and discourses of childhood, family and society in National Curriculum Framework (NCF) as it relates to children’s everyday contexts. I throw light on how the curriculum’s discourses relate to the diverse South African settings, child rearing practices and world-views, and how they interact with normative discourses of South African policy and global early childhood frameworks. The NCF…

Revealing colonial power relations in early childhood policy making: An autoethnographic story on selective evidence

2021

The COVID-19 pandemic exposes uncertainty, instability and glaring inequality that requires urgent global policy decisions. Historically, bureaucrats regard uncertainty as the enemy and look for tested solutions (Stevens, 2011). In contrast, Fielding & Moss (2010) acknowledge an uncertain future and encourage shifting policy making towards the search for possibilities instead of replicating singular solutions. Escobar (2020) advocates for pluriversal politics, with many possibilities created through collective decision-making by autonomous interlinked networks. In this paper, I combine autoethnography with policy analysis drawing on my own experience in South African early childhood pol…

Participation in Social Media: Studying Explicit and Implicit Forms of Participation in Communicative Social Networks

2016

The diverse forms of participation in social media raise many methodological and ethical issues that should be acknowledged in research. In this paper, participation in social media is studied by utilising the framework of explicit and implicit participation. The focus is on the communicative and communal aspects of social media. The aim of the paper is to promote the reconsideration of what constitutes participation when online users create connections rather than content. The underlying argument is that research on social media and the development of methods should concentrate more on implicit forms of participation.

Continuum: A spatiotemporal data model to represent and qualify filiation relationships

2013

International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…

Understanding Urban Fabric with the OH_FET model based on Social Use, Space and Time

2008

The proposed principle for understanding the urban fabric is based on considering the town as a set of complex objects, taking a systemic approach. The town system used to study the urban fabric over large time spans is composed of three sub-systems relating to historical objects from the level of the excavation to that of the former urban space: function (social use), space (location, surface area and morphology) and time (dating, duration and chronology). The historical object is the analytical unit of the space studied. It is the Cartesian product of the three sets, Social use, Space and Time, from which it stems. On the basis of this process, the Historical Object (OH) is broken down in…
