An examination of nonresponse in a study on daily family life: I do not have time to participate, but I can tell you something about our life
2012
The aim of this study was to look at the issue of nonresponse and self-selection bias in the context of a family study on daily family life. Data on the participating families and refusers were gathered as part of the wider Palette study in which questionnaires and diaries were used as data collection methods. On the basis of these data (N = 208 participating families and 119 refuser families), we profile the families left outside the study. The parents who declined to participate in the Palette study were asked to fill in a short refusal form, which included questions concerning their family background and reasons for refusal, and they were also asked to write freely about their everyday l…
Mesure de la performance des agences bancaires par une approche DEA
2005
Using a DEA framework (Data Envelopment Analysis), we develop new performance indicators for integrated retail networks. A methodological discussion leads us to propose a productivity indicator which respects the criteria of controllability and transversal coherence. We then formalise the relationship between a performance indicator of a network's headquarters and the productivity of its various retailers. Finally, we combine these new indicators in crafting a management tool amenable to a system of balanced scorecards.
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
Assessing travel time-based accessibility to outdoor ice skating fields for children in Helsinki during the COVID-19 pandemic
2022
This paper was written within the research project called “Equality in suburban physical activity environments, YLLI” (in Finnish: Yhdenvertainen liikunnallinen lähiö, YLLI) funded by the Suburban Programme 2020–2022 (in Finnish: Lähiöohjelma 2020–2022, decision number VN/10837/2020). Informal sport is central to Finnish children’s leisure and physical activity time. This paper aims to build a better understanding of the travel time-based accessibility to informal sports facilities, specifically to ice skating fields, for children and adolescents (aged 7–19) in the city of Helsinki. We focused on the winter of 2020–2021 because COVID-19 restrictions on indoor activities resulted in ice skat…
Creation of a food taste database using an in-home profile method
2013
Poster (1 page) ; http://www.pangborn2013.com/; International audience; The purpose of this study was to create a food taste database using an innovative in-home profile method and to have an overview on the sensory sapid world we face in our diet. The intensity of salty, sweet, acid and bitter tastes were scored using universal scales proposed within the Spectrum™ method (Muñoz and Civille, 1992) and newly developed scales for umami taste and fattiness. The in-home taste profile method was composed of two phases. The first phase consisted in an intensive training in laboratory (55 h). The second one was the in-home measurements phase (8 months) during which 12 panellists had to rate the ta…
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…
CCTVCV: Computer Vision model/dataset supporting CCTV forensics and privacy applications
2022
The increased, widespread, unwarranted, and unaccountable use of Closed-Circuit TeleVision (CCTV) cameras globally has raised concerns about privacy risks for the last several decades. Recent technological advances implemented in CCTV cameras, such as Artificial Intelligence (AI)-based facial recognition and Internet of Things (IoT) connectivity, fuel further concerns among privacy advocates. Machine learning and computer vision automated solutions may prove necessary and efficient to assist CCTV forensics of various types. In this paper, we introduce and release the first and only computer vision models are compatible with Microsoft common object in context (MS COCO) and capable of accurately…
Monilukutaito lukion historian opetuksessa
2019
Lukion opetussuunnitelman perusteisiin (Opetushallitus, 2015) on sisällytetty Monilukutaidot ja media -aihekokonaisuus, jossa monilukutaito määritellään taitoina tulkita ja tuottaa erilaisia tekstejä. Jokaisen opettajan odotetaan opettavan oman tiedonalansa tekstitaitoja, joiden alakohtaisuus pohjaa tiedonmuodostuksen käytänteisiin. Tällä korostetaan eri oppiaineiden sisältötiedon hallinnan lisäksi myös tekstitaitojen kehittymistä kaikissa oppiaineissa. Tässä artikkelissa tarkastelemme, millaisena monilukutaito ja erityisesti tiedonalan tekstitaitojen opetus näyttäytyvät lukion historian opetuksessa. Tutkimuksen aineisto on kerätty suomenkielisten lukioiden historian opettajille suunnatun k…
The Tucker tensor decomposition for data analysis: capabilities and advantages
2022
Tensors are powerful multi-dimensional mathematical objects, that easily embed various data models such as relational, graph, time series, etc. Furthermore, tensor decomposition operators are of great utility to reveal hidden patterns and complex relationships in data. In this article, we propose to study the analytical capabilities of the Tucker decomposition, as well as the differences brought by its major algorithms. We demonstrate these differences through practical examples on several datasets having a ground truth. It is a preliminary work to add the Tucker decomposition to the Tensor Data Model, a model aiming to make tensors data-centric, and to optimize operators in order to enable…
Creating the Socio-technical Context Needed to Derive Benefits from Big Data Initiatives in Healthcare
2021
The application of big data in healthcare typifies a complex socio-technical sys- tem. However, although research and practice have advanced the technical aspects of big data, comparable advancements in the social aspects (i.e., human and structural aspects) are lagging. Literature, especially on socio-technical theory, suggests that organizations may only derive benefits from big data initiatives when technical initiatives are adequate- ly complemented by social interventions. Thus, seeing that big data is receiving consider- able attention in healthcare, researchers have called for further research into the social aspects of the application of big data in healthcare. Adopting a socio-tech…
