Volcanic climate forcing preceding the inception of the Younger Dryas: Implications for tracing the Laacher See eruption
2021
Climatic warming from the last glacial maximum to the current interglacial period was punctuated by a similar to 1300 years long cold period, commonly referred to as the Younger Dryas (YD). Several hypotheses have been proposed for the mechanism triggering the abrupt inception of the YD, including freshwater forcing, an extra-terrestrial impact, and aerosols from volcanic eruptions. Here, we use synchronised sulphate and sulphur records from both Greenland and Antarctic ice cores to reconstruct volcanic forcing between 13,200-12,800 a BPGICC05 (years before 1950 CE on the Greenland Ice Core Chronology 2005; GICC05). This continuous reconstruction of stratospheric sulphur injections highligh…
Power training and postmenopausal hormone therapy affect transcriptional control of specific co-regulated gene clusters in skeletal muscle
2010
At the moment, there is no clear molecular explanation for the steeper decline in muscle performance after menopause or the mechanisms of counteractive treatments. The goal of this genome-wide study was to identify the genes and gene clusters through which power training (PT) comprising jumping activities or estrogen containing hormone replacement therapy (HRT) may affect skeletal muscle properties after menopause. We used musculus vastus lateralis samples from early stage postmenopausal (50–57 years old) women participating in a yearlong randomized double-blind placebo-controlled trial with PT and HRT interventions. Using microarray platform with over 24,000 probes, we identified 665 diffe…
Is Finland Different? Quality of Work Among Finnish and European Employees
2010
The issue of the quality of work-life has risen in popularity due to concerns about the economic and social sustainability of European societies. Throughout the continent, global competition, technological change and the intensification of work are common developments which are seen to affect the well-being of the workforce. Nevertheless, European countries differ substantially in terms of job quality. According to earlier research, employees in Sweden and Denmark (and to lesser extent in Finland) report a higher quality of work tasks than elsewhere in Europe. The aim of this paper was to investigate, in a cross-national context using multivariate techniques, whether job quality in Finland …
Quality of life (QOL) of older adult community choral singers in Finland.
2013
ABSTRACTBackground: Enhancing quality of life (QOL) of older adults is an international area of focus. Identifying factors and experiences that contribute to QOL of older adults helps promote optimal levels of functioning. This study examines the relationship between perceived benefits associated with choral singing and QOL among community-dwelling older adults.Methods: One hundred seventeen older adults who sing in community choirs in Jyväskylä, Finland, completed self-report measures of QOL (WHOQOL-Bref), depressive symptoms, and a questionnaire about the benefits of singing in choir. Correlational analyses and linear regression models were used to examine the association between the bene…
IAS 36 -standardin mukaisen liikearvon arvonalentumistestauksen raportoinnin laatu ja siihen vaikuttavat tekijät suomalaisissa pörssiyhtiöissä tilika…
2014
Tutkielma käsittelee IAS 36 -standardin mukaisen liikearvon arvonalentumistestauksen rapor-tointiohjeistuksen noudattamista ja tätä kautta määriteltävää liikearvoraportoinnin laatua sekä laatuun vaikuttavia tekijöitä. Otoksena ovat suomalaiset pörssiyhtiöt, joiden taseen loppusummasta liikearvo muodosti vähintään 10 prosentin osuuden tilikaudella 2012. Laadun mittaamiseksi muodostettiin pisteytysmittaristo, jonka avulla laatu voitiin esittää asteikolla 0 – 100 %. Laatua mitattiin myös raportoinnin osa-alueittain. Osa-alueita olivat yleiset kysymykset, johdon ennustejakso, terminaalijakso, herkkyysanalyysi sekä raportoinnin tietolähteet. Tutkitut liikearvon arvonalentumistestauksen raportoin…
Teatteritaiteen perusopetuksen kokemuksellisen laadun edellytykset
2017
Pro gradu –työssäni tutkin teatteritaiteen perusopetuksessa koettua laatua opetukseen osallistuneiden oppilaiden näkökulmasta. Tutkimukseni perustana on deweyläinen pragmatismi, jossa teoria ja empiria solmiutuvat yhteen. Työni teoreettisessa osassa kehitän kriittisen ja tulkinnallisen analyysin kautta kokemuksellisen laadun –käsitteen. Se on teoreettinen vastine välittömälle, merkitykselliselle ja tyydyttävälle kokemiselle, joka tapahtuu käytännössä. Käsite pohjautuu John Deweyn kokemusfilosofiaan ja Robert Pirsigin näkemykseen, jossa laatu tunnistetaan välittömässä jokapäiväisessä kokemisessa. Tutkimukseni päätehtävä on vastata kysymykseen, millaiset tekijät ovat kokemuksellisen laadun ed…

Downlink channel access performance of NR-U: Impact of numerology and mini-slots on coexistence with Wi-Fi in the 5 GHz band
2020
Coexistence between cellular systems and Wi-Fi gained the attention of the research community when LTE License Assisted Access (LAA) entered the unlicensed band. The recent introduction of NR-U as part of 5G introduces new coexistence opportunities because it implements scalable numerology (flexible subcarrier spacing and OFDM symbol lengths), and non-slot based scheduling (mini-slots), which considerably impact channel access. This paper analyzes the impact of NR-U settings on its coexistence with Wi-Fi networks and compares it with LAA operation using simulations and experiments. First, we propose a downlink channel access simulation model, which addresses the problem of the dependency an…
Engaged or Not? A Comparative Study on Factors Inducing Work Engagement in Call Center and Service Sector Work.
2013
The aim of this study was to compare the possibilities of experiencing positive well-being in call centers and other service sector work. The article focuses on the prevalence of working conditions (job demands, autonomy, and social support) in call centers and at other service sector workplaces and how these factors are related to work engagement. In addition, we examine whether the relationships are divergent in call centers in comparison to other service sector work. Analysis is based on the data provided by the “Quality of Life in Changing Europe” project. The survey data were collected from service sector organizations (retail, banking, and insurance) and a telecom organization’s call …
