Digitaalinen diskurssi työelämän kontekstissa – menetelmällisiä haasteita ja ratkaisuehdotuksia
2020
Digital technologies have become an inseparable part of most workplace activities. In this article, we discuss the study of digital work in the context of complex organizational practices. We lay out some methodological challenges and suggest some possible solutions to them. Firstly, we contend that we should take into consideration the multimedial nature of organizational practices. Secondly, several kinds of data – such as video-recordings of face-to-face encounters, screenshots from digital platforms, ethnographic observation and interviews – may be needed to gain an understanding of such practices. Thirdly, the analyst needs to pay attention to the affordances of the media that the part…
The XENON1T Dark Matter Experiment
2017
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso (LNGS) is the first WIMP dark matter detector operating with a liquid xenon target mass above the ton-scale. Out of its 3.2 t liquid xenon inventory, 2.0 t constitute the active target of the dual-phase time projection chamber. The scintillation and ionization signals from particle interactions are detected with low-background photomultipliers. This article describes the XENON1T instrument and its subsystems as well as strategies to achieve an unprecedented low background level. First results on the detector response and the performance of the subsystems are also presented. © 2017, The Author(s).
XENON1T Dark Matter Data Analysis: Signal Reconstruction, Calibration and Event Selection
2019
The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above $6\,$GeV/$c^2$ scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric $\mathrm{ton}\times\mathrm{year}$ exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In pa…
How to apply privacy by design in osint and big data analytics?
2019
In a world where technology grows exponentially, more information is available to us every day. States and their governments have collected information on their citizens for a long time now. On the other hand, people give out more and more personal information voluntarily through social media. Information available on the Internet is easier to analyze with modern technologies and the original source of information is also easier to track down. Information is available to all of us and that information can be used to investigate personal data, defeat competitors in a corporate world, solve crimes or even win wars. This study analyses open source intelligence (OSINT) and big data analytics (B…
Factors behind Leisure-Time Physical Activity Behavior Based on Finnish Twin Studies: The Role of Genetic and Environmental Influences and the Role o…
2014
Different approaches are being taken to clarify the role of various factors in the development of physical activity behaviors. Genetic studies are a new area of physical activity research and also the motives for physical activity have been widely studied. The purpose of this paper is to review the findings emerging from the longitudinal genetic studies on leisure-time physical activity and to evaluate the associations between motivational factors and leisure-time physical activity. The focus is to review recent findings of longitudinal Finnish twin studies. The results of the latest longitudinal Finnish twin studies point to the existence of age-specific genetic and environmental influence…
Ympäristövaikutusten arviointiin liittyvät selvitykset maatuulivoimahankkeissa
2016
Euroopan Unioni on asettanut Suomelle tavoitteeksi tuottaa 38 % energian loppukulutuksesta uusiutuvilla energiantuotantolähteillä vuonna 2020. Tuulivoima on Suomessa varsin uusi energiantuotantomuoto, minkä vuoksi tuulivoimahankkeiden YVA-menettelyjen (ympäristövaikutusten arviointimenettely) toteuttamistavat vaihtelevat paljon hankkeiden välillä. Tässä tutkimuksessa selvitettiin, miten maatuulivoimaloiden ympäristövaikutuksia on Suomessa arvioitu. Tarkastelu rajattiin tuulivoiman merkittävimpiin vaikutuksiin ja tutkimuksen laatijan omiin mielenkiinnon kohteisiin. Tutkimus on toteutettu dokumenttianalyysinä ennen vuoden 2014 syksyä valmistuneista YVA-selostuksista kaksivaiheisella koodausme…
Consumption of ultra-processed foods : an assessment of the literature on determinants of ultra-processed food consumption and an investigation of th…
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Background Highly processed foods have been classified as ultra-processed, and consumption of such foodstuffs have expanded rapidly over the last decades. Ultra-processed foods are characterized as being accessible, attractive, palatable and often time-saving. An excess intake of ultra-processed foods has been associated with increased risk of e.g. overweight/obesity and diabetes type II. The aim of this master’s project was to investigate factors influencing consumption of ultra-processed foods. This resulted in one review paper on young adults, and one cross-sectional study where the association between time scarcity and ultra…
Meeting the WHO 24-h guidelines among 2–6-year-old children by family socioeconomic status before and during the COVID-19 pandemic : a repeated cross…
2023
Background The World Health Organization (WHO) has developed guidelines for 24-h physical activity (PA), sedentary behaviour and sleep for young children. Lower socioeconomic status (SES) has been linked to a lower likelihood of meeting these guidelines. The outbreak of the novel coronavirus disease (COVID-19) raised concerns about young children’s opportunities to meet the guidelines. The study focused on the prevalence of meeting the WHO’s 24-h guidelines on screen time (ST), PA and sleep among 2–6-year-old children, in association with family SES, before COVID-19 outbreak in 2019, and during the pandemic in 2020 and 2021 in Finland. Methods Data were collected at three timepoints by an o…
Judaizm i chrześcijaństwo - dwie drogi zbawienia : filary myślenia religijnego Franza Rosenzweiga
2017
Franz Rosenzweig belongs to a group of philosophers who have never crossed the threshold of a wider popularity. This does not change the fact that his philosophical thought is significant. Article aims to aprximate the key issues which make the specifics of his philosophy. These include, above all, a new concept of experience, developed in opposition to the narrower interpretations of Kant and British empiricists. Absolute empiricism, as he Rosenzweig describes his philosophy, it is possible to und erstand only through taking into account the categories of time and the category the Other. The main part of my article concerns this problem. Finally, my considerations going towards explaining …
