Luokan työrauhaan vaikuttavat tekijät : sekamallin sovellus

2017

Tämän pro gradu -tutkielman tarkoituksena oli tarkastella koululuokkien työrauhaan vaikuttavia tekijöitä. Aineistona käytettiin Niilo Mäki Instituutin Prokoulu-projektin tutkimusaineistoa. Vastemuuttujana käytettiin oppilaan arvioimaa luokan työrauhaa. Selittäviksi muuttujiksi asetettiin aiemman tutkimustiedon perusteella oppilaan arvioita erilaisista sosiaalisista suhteista ja käyttäytymiseen liittyvistä asioista, luokan opettajan ominaisuuksia ja arvioita koulun toimintakulttuurista sekä yleisiä luokkaan liittyviä ominaisuuksia. Analyysimenetelmänä käytettiin hierarkkista lineaarista regressiomallia, ts. lineaarista sekamallia, johon asetettiin oppilas-, luokka- ja koulutasot. Sekamallin …

Ordered fuzzy rules generation based on incremental dataset

2021

This paper proposes a novel approach for building transparent knowledge-based systems by generating interpretable fuzzy rules that allow for present dependences between quantitative variables by accounting for uncertainty and the dynamics of their values. In the approach, IF-THEN rules are used to show the conditional relationship between the ordered fuzzy numbers, which contain additional information about the tendencies of variables' value changes. This paper elaborates an approach of mining ordered fuzzy rules from numerical data included in an incremental database. This approach develops the ability to record uncertainty and its change in the context of rapidly changing data. In additio…

Reconfiguration de l'ordre mondial de l'information et de la communication: implications et incidences de la chaine Al Jazira

2014

Reconfiguración del orden mundial de la información y de la comunicación: implicaciones e incidencias de la cadena Al Yazira La información es la base de la toma de decisión. Los gobiernos a través de la Historia entendieron la influencia de este soft power en su política interior como exterior. Los Estados nacidos de la descolonización notaron sobre todo el desequilibrio de sus fuentes y sus consecuencias en términos de dominación cultural e intelectual. Esta tesis entonces pregunta cómo dar una voz al « Sur ». Analiza el enfoque de los principales actores implicados en el ideal de un « Nuevo orden mundial de la información y de la comunicación »: el Movimiento de los No-alineados y la UNE…

Extensions of representable linear functionals to unitized quasi *-algebras

2013

This paper starts from noting that, under certain conditions, *-representability and extensibility to the unitized *-algebra of a positive linear functional, defined on a *-algebra without unit, are equivalent. Here some conditions for the equivalence of the same concepts for a hermitian linear functional defined on a quasi *-algebra $(\A,\Ao)$ without unit are given. The approach is twofold: on the one hand, conditions for the equivalence are exhibited by introducing a condition for the *- representability of the extension of a *-representable functional to the unitized quasi *-algebra, on the other hand a *-representable extension to the unitization of a hermitian linear functional by mea…

Nonlinear black-box models for short-term forecasting of air temperature in the town of Palermo

2011

Weather data are crucial to correctly design buildings and their heating and cooling systems and to assess their energy performances. In the intensely urbanized towns the effect of climatic parameters is further emphasized by the Urban Heat Island (UHI) phenomenon, known as the increase in the air temperature of urban areas, compared to the one measured in the extra-urban areas. The analysis of the heat island needs detailed local climate data which can be collected only by a dedicated weather monitoring system. The Department of Energy and Environmental Researches of the University of Palermo (Italy) has built up a weather monitoring system that works 24 hours per day and makes data availa…

Female reproductive factors are associated with objectively measured physical activity in middle-aged women

2017

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women. In addition, we examined the association of physical activity with female reproductive factors at midlife. The study population consisted of 647 women …

Valkosolupitoisuuksien bayesilainen mallintaminen lasten leukemian ylläpitohoidossa

2018

Lasten akuutin lymfoblastileukemian ylläpitovaiheen hoidossa tehtävät lääkeannostuspäätökset pohjataan nykyisin potilaan veren valkosolupitoisuuteen, joka on hoidon tehokkuudesta kertova tekijä. Potilaalle sopiva lääkeannostus on hoidon onnistumisen ja turvallisuuden kannalta tärkeä, mutta sen löytäminen on vaikeaa, sillä annettu lääkitys näkyy valkosolupitoisuudessa viiveellä, ja potilaiden elimistön reagointi lääkitykseen on yksilöllistä. Sopivan lääkeannostuksen löytämistä hankaloittavat myös hoidonaikaiset tulehdukset, jotka voivat muuttaa valkosolupitoisuutta hetkellisesti. Työ käsittelee akuuttiin lymfoblastileukemiaan sairastuneiden suomalaisten potilaiden veren valkosolupitoisuuden …

The effectiveness of the HIPPA intervention in the sociocultural environment of ECEC physical activity

2023

Studies have shown that, on average, children’s physical activity (PA) levels in early childhood education and care (ECEC) environments are low, thus opening up the possibility of interventions. We examined the effect of the teacher-implemented one-year long ‘home-and-childcare-based intervention to promote physical activity’ (HIPPA) study on children’s PA in ECEC settings in Finland. Participating four-year-old children (N = 128) were cluster-randomised into two groups, intervention (seven childcare centres) and control (seven childcare centres), in autumn 2011. The children were observed directly during their ECEC times. Multilevel linear analysis was used to test the PA differences betwe…

Diversity in warning coloration: selective paradox or the norm?

2019

Aposematic theory has historically predicted that predators should select for warning signals to converge on a single form, as a result of frequency-dependent learning. However, widespread variation in warning signals is observed across closely related species, populations and, most problematically for evolutionary biologists, among individuals in the same population. Recent research has yielded an increased awareness of this diversity, challenging the paradigm of signal monomorphy in aposematic animals. Here we provide a comprehensive synthesis of these disparate lines of investigation, identifying within them three broad classes of explanation for variation in aposematic warning signals: …
