Scalable implementation of dependence clustering in Apache Spark
2017
This article proposes a scalable version of the Dependence Clustering algorithm which belongs to the class of spectral clustering methods. The method is implemented in Apache Spark using GraphX API primitives. Moreover, a fast approximate diffusion procedure that enables algorithms of spectral clustering type in Spark environment is introduced. In addition, the proposed algorithm is benchmarked against Spectral clustering. Results of applying the method to real-life data allow concluding that the implementation scales well, yet demonstrating good performance for densely connected graphs. peerReviewed
Visualising maritime vessel open data for better situational awareness in ice conditions
2018
Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…
Estimating Regional Input Coefficients and Multipliers: The Use of FLQ is Not a Gamble
2014
Flegg A. T. and Tohmo T. Estimating regional input coefficients and multipliers: the use of FLQ is not a gamble, Regional Studies. This paper re-examines the Finnish evidence presented by Lehtonen and Tykkylainen on the use of location quotients (LQs) in estimating regional input coefficients and multipliers. They argue that the choice of an LQ-based method is a gamble and that there is no single method that can be recommended for general use. It is contended here that this evidence is erroneous and that the FLQ (Flegg's location quotient) yields results far superior to those from competing formulae, so it should provide a satisfactory way of generating an initial set of input coefficients.…
The relationship between context, structure, and processes with outcomes of 6 regional diabetes networks in Europe
2018
BackgroundWhile health service provisioning for the chronic condition Type 2 Diabetes (T2D) often involves a network of organisations and professionals, most evidence on the relationships between the structures and processes of service provisioning and the outcomes considers single organisations or solo practitioners. Extending Donabedian's Structure-Process-Outcome (SPO) model, we investigate how differences in quality of life, effective coverage of diabetes, and service satisfaction are associated with differences in the structures, processes, and context of T2D services in six regions in Finland, Germany, Greece, Netherlands, Spain, and UK.MethodsData collection consisted of: a) systemat…
Moral distress among social workers : the role of insufficient resources
2015
The present study examined moral distress among Finnish social workers and the role of perceived resource insufficiencies in explaining it. The aim was to shed light on this understudied phenomenon in the field of social welfare. The study focused on work-related moral distress, defined as impaired wellbeing that is connected to the continual inability to implement actions that one considers morally appropriate. The survey data were collected with an electronic questionnaire between the years 2011 and 2012. The respondents (n = 817) were social workers in the public social welfare services and the overall response rate was 46.5 per cent. Nearly 11 per cent of the respondents reported experi…
Equal access to the top? Measuring selection into finnish academia
2019
In this article, we draw a parallel between equality of opportunity in educational transitions and equality of opportunity in academic careers. In both cases, many methodological problems can be ameliorated by the use of longitudinal rather than cross-sectional data. We illustrate this point by using Finnish full-population register data to follow the educational and academic careers of the 1964–1966 birth cohorts from birth to the present day. We show how the Finnish professoriate is highly selected both in terms of parental background and in terms of gender. Individuals of different backgrounds differ greatly in the likelihood of completing different educational and academic transitions, …
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…
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…
