Solvenssi II -tyyppisen vakavaraisuussäännöstön vaikutus työeläkeyhtiönsijoitustoimintaan
2011
Tässä tutkimuksessa verrataan Solvenssi II -tyyppisen vakavaraisuussäännöstön ja Suomen yksityisen sektorin työeläkejärjestelmän vakavaraisuussäännöstön eroja ja vaikutusta eläkelaitosten sijoitustoimintaan. Tutkimuksessa kehitetään myös uusi sijoitustuottomalli, joka laajentaa aiempia malleja huomioiden luottoriskit ja vaihtoehtoiset sijoitukset. Tutkimusmetodologialla pystytään löytämään vakavaraisuusjärjestelmien heikkouksia sekä vertaamaan sijoitusallokaatioita ja -tuottoja näissä kahdessa kehikossa. Tulosten perusteella Solvenssi II -tyyppinen kehikko ohjaisi eläkelaitoksia vähentämään kiinteistösijoituksia ja lisäämään vaihtoehtoisia sijoituksia. Vakavaraisuussäännöstön uusiminen ei m…
Assessment of Microstressors in Adults: Questionnaire Development and Ecological Validation of the Mainz Inventory of Microstressors
2020
Background Many existing scales for microstressor assessment do not differentiate between objective (ie, observable) stressor events and stressful cognitions or concerns. They often mix items assessing objective stressor events with items measuring other aspects of stress, such as perceived stressor severity, the evoked stress reaction, or further consequences on health, which may result in spurious associations in studies that include other questionnaires that measure such constructs. Most scales were developed several decades ago; therefore, modern life stressors may not be represented. Ecological momentary assessment (EMA) allows for sampling of current behaviors and experiences in real…
Early Health, Risk Aversion and Stock Market Participation
2019
To examine the relationship between early health status and financial decisions in adulthood, we link information on birth weight in 1966 from the Northern Finland Birth Cohort to data from the Finnish Central Securities Depository over the period of 19952010. We find that persons predisposed to poor health status in early childhood (indicated by low birth weight) avoid participating in the stock market in adulthood. The link between birth weight and stock market participation is partially explained by the fact that poor early health status leads to risk aversion. Early health status is not significantly related to the portfolio’s value-growth tilt. nonPeerReviewed
Neuronal effects of Sugammadex in combination with Rocuronium or Vecuronium.
2017
Rocuronium (ROC) and Vecuronium (VEC) are the most currently used steroidal non-depolarizing neuromuscular blocking (MNB) agents. Sugammadex (SUG) rapidly reverses steroidal NMB agents after anaesthesia. The present study was conducted in order to evaluate neuronal effects of SUG alone and in combination with both ROC and VEC. Using MTT, CASP-3 activity and Western-blot we determined the toxicity of SUG, ROC or VEC in neurons in primary culture. SUG induces apoptosis/necrosis in neurons in primary culture and increases cytochrome C (CytC), apoptosis-inducing factor (AIF), Smac/Diablo and Caspase 3 (CASP-3) protein expression. Our results also demonstrated that both ROC and VEC prevent these…
Exposure assessment of animals to sediments contaminated by pulp and paper mills
2007
Sellu- ja paperiteollisuuden jätevesillä on haittavaikutuksia kaloihin ja muihin vesieläimiin vielä senkin jälkeen, kun vierasaineet ovat hautautuneet vesistön pohjaan osaksi sedimenttiä eli järven pohjaan kerrostunutta ainesta. Vierasaineet voivat vapautua takaisin eliöille saatavaan muotoon, jos vesi sekoittuu voimakkaasti esimerkiksi ruoppauksen tai rajujen myrskyjen yhteydessä. Myös sedimentissä asustaviin pohjaeläimiin kertyy sellu- ja paperiteollisuuden vierasaineita. FM Päivi Meriläinen tutki väitöskirjassaan sellu- ja paperiteollisuuden saastuttamien sedimenttien altistamia vesieläimiä Etelä-Saimaan alueella. Sellu- ja paperiteollisuuden jätevesien haittavaikutuksia kaloihin ja muih…
Sustaining Attention for a Prolonged Duration Affects Dynamic Organizations of Frequency-Specific Functional Connectivity
2020
Sustained attention encompasses a cascade of fundamental functions. The human ability to implement a sustained attention task is supported by brain networks that dynamically formed and dissolved through oscillatory synchronization. The decrement of vigilance induced by prolonged task engagement affects sustained attention. However, little is known about which stage or combinations are affected by vigilance decrement. Here, we applied an analysis framework composed of weighted phase lag index (wPLI) and tensor component analysis (TCA) to an EEG dataset collected during 80 min sustained attention task to examine the electrophysiological basis of such effect. We aimed to characterize the phase…
Electrochemical sensor for phosphate ions based on laser scriber reduced graphene oxide
2022
This preliminary work shows a new and innovative way to produce laser scribed reduced graphene oxide (LSGO) electrodes using different porous substrates (ranging from paper to plastic and fabric). The obtained electrodes were also tested as electrochemical sensors towards the detection of phosphate ions in water. To obtain the electrodes, a water suspension of GO was filtered on top of substrate (such as Whatman® filter paper) and a complete sensor was obtained from its reduction using a CO2 laser. The electrode is composed of working and counter electrodes made of LSGO and a reference electrode of a Ag/AgCl obtained by using a commercial AgCl conductive paste. Phosphate ions were detected …
