Sport clubs' health promotion activities for the surrounging communities : a comparative case study of Columbus Blue Jackets, HJK and Sotkamon Jymy
2014
ABSTRACT The level of physical activity continues to decrease globally. Therefore it is important to explore new ways of promoting physical activity and healthy life style. Sport clubs are an excellent setting for physical activity and health related programs targeted for the surrounding community due to their visibility, popularity and image. They offer also companies a possibility to conduct their health related corporate social responsibility activities by supporting and cooperating with the club. Despite its importance there are not many studies related to the role of sport clubs as health promoters. The aim of this research is to explore what kind of health promotion activities sport c…
Mental health profiles of Finnish adolescents before and after the peak of the COVID-19 pandemic
2023
Abstract Background The COVID-19 pandemic has had implications for adolescents’ interpersonal relationships, communication patterns, education, recreational activities and well-being. An understanding of the impact of the pandemic on their mental health is crucial in measures to promote the post-pandemic recovery. Using a person-centered approach, the current study aimed to identify mental health profiles in two cross-sectional samples of Finnish adolescents before and after the peak of the pandemic, and to examine how socio-demographic and psychosocial factors, academic expectations, health literacy, and self-rated health are associated with the emerging profiles. Methods and findings Surv…
Weighted Clustering of Sparse Educational Data
2015
Clustering as an unsupervised technique is predominantly used in unweighted settings. In this paper, we present an efficient version of a robust clustering algorithm for sparse educational data that takes the weights, aligning a sample with the corresponding population, into account. The algorithm is utilized to divide the Finnish student population of PISA 2012 (the latest data from the Programme for International Student Assessment) into groups, according to their attitudes and perceptions towards mathematics, for which one third of the data is missing. Furthermore, necessary modifications of three cluster indices to reveal an appropriate number of groups are proposed and demonstrated. pe…
SparseHC: A Memory-efficient Online Hierarchical Clustering Algorithm
2014
Computing a hierarchical clustering of objects from a pairwise distance matrix is an important algorithmic kernel in computational science. Since the storage of this matrix requires quadratic space with respect to the number of objects, the design of memory-efficient approaches is of high importance to this research area. In this paper, we address this problem by presenting a memory-efficient online hierarchical clustering algorithm called SparseHC. SparseHC scans a sorted and possibly sparse distance matrix chunk-by-chunk. Meanwhile, a dendrogram is built by merging cluster pairs as and when the distance between them is determined to be the smallest among all remaining cluster pairs. The k…
Detecting clusters in spatially correlated waveforms
2017
Seismic networks often record signals characterized by similar shapes that provide important information according to their geographic positions. We propose an approach to identify homogeneous clusters of seismic waves, combining analysis of waveforms with metadata and spectrogram information. In waveforms clustering, cross-correlation measures between signals may presents some limitations, so we refer to more recent contributes relating data-depth based clustering analysis. The mechanism for alignment is also an important topic of the analysis: warping (or aligning) procedures identify nuisance effects in phase variation, that, if ignored, may result in a possible loss of information and t…

Spatio-temporal Dynamical Analysis of Brain Activity during Mental Fatigue Process
2021
Mental fatigue is a common phenomenon with implicit and multidimensional properties. It brings dynamic changes of functional brain networks. However, the challenging problem of false positives appears when the connectivity is estimated by Electroencephalography (EEG). In this paper, we propose a novel framework based on spatial clustering to explore the sources of mental fatigue and functional activity changes caused by them. To suppress the false positive observations, spatial clustering is implemented in brain networks. The nodes extracted by spatial clustering are registered back to functional magnetic resonance imaging (fMRI) source space to determined the sources of mental fatigue. The…
Forme necessarie dell’abitare: il ruolo dello spazio pubblico nei contesti informali di Bogotá e Medellín
2015
Gli spazi collettivi rappresentano un beneficio per la comunità, specialmente in quei contesti urbani “informali”, manifestazione fisica del bisogno primordiale dell’abitare. La straordinaria e recente rigenerazione urbana e sociale conquistata dalle città colombiane di Bogotá e Medellín, è un notevole esempio di strategie politiche e progettuali innovative, risultato delle azioni congiunte di politici, professionisti e cittadinanza, che fondano le proprie radici sul riconoscimento del ruolo sociale ed urbano dello spazio pubblico, elemento ristrutturante il tessuto urbano ed umano. La progettazione di nuovi spazi collettivi nei contesti urbani più fragili, più marginali ed abbandonati dell…
La produzione dello spazio democratico per il soddisfacimento del bene comune
2015
Nella storia della città lo spazio pubblico e le attrezzature collettive rappresentano da sempre luoghi di coesione, interscambio, relazione, condivisione e cooperazione per l’uomo, il quale manifesta il bisogno di abitare un luogo in cui possa relazionarsi con gli altri, formando una comunità ed una vita pubblica. Gli spazi collettivi rappresentano pertanto un beneficio per la comunità, in quanto diaframmi tra la sfera pubblica e la sfera privata, luoghi di uguaglianza e di democrazia, ove si alimenta il 'capitale sociale' e si annulla l’esclusione sociale e spaziale, a favore di un interscambio socio-culturale tra individui diversi. Nelle città globalizzate la disuguaglianza nella distrib…
