Regulation of motility of cells from marine sponges by calcium ions

1996

Sponges are known not to contain muscle and nerve cells. Since sponge cells are characterized by high motility we determined the effect of intracellular calcium ion concentration ([Ca2+]i) on their motility. Addition of the Ca2+ ionophore ionomycin to dissociated cells from the marine sponge Suberites domuncula caused in Ca(2+)-containing artificial seawater (ASW) an increase in motility from 0.2 micron/min (absence of the ionophore) to 3.7 microns/min (presence of ionomycin). When the experiments were performed in Ca(2+)-free medium, no effect of ionomycin could be observed. In parallel experiments the changes of [Ca2+]i using the dye Fura-2 were measured. The experiments revealed that ion…

Hahmottamisen haasteet ja kuulumisen rakentuminen lapsen arjessa

2015

Tutkimuksen tarkoituksena oli lisätä ymmärrystä lapsen, jolla on hahmottamisen haasteita ja ADHD, arjesta. Keskeisenä nähtiin lapsen näkökulma, jolloin oire- ja ongelmakeskeisyydestä pyrittiin tietoisesti etääntymään. Tutkimus asettui lapsuudentutkimuksen alueelle, ottaen huomioon sen keskeiset metodologiset lähtökohdat. Aineisto kerättiin lapsia haastattelemalla ja havainnoimalla. Tutkimukseen osallistui 7 lasta. Aineisto analysoitiin sisällönanalyysin mukaisesti kuulumisen (belonging) käsitettä hyödyntäen. Lapsen kuulumisen rakentumisen kannalta tärkeää oli arjen helppous ja yhteenkuuluvuus. Helppoutta ja yhteenkuuluvuutta loivat läheiset ja tärkeät ihmissuhteet, joihin lapsi kiinnittyi j…

2016

Maisterintutkielmani on projektikuvaus, jossa kuvataan laulujuhlien järjestämisprosessi suunnittelusta toteutukseen ja toteutuksen arviointiin. Kuvaan juhlaideaa, suunnittelua ja toteutusta. Lasten laulujuhlien idean lähtökohtana on Oulussa vietetyt Lasten laulujuhlat vuosina 2010 ja 2013. Laulujuhlille mukaan kutsuttiin 13 kuntaa, joista 11 vastasi haasteeseen. Juhlat kokosivat Haapavedelle 21.4.2016 yli 800 7-12- vuotiasta lasta. Tutkielmani on sekä tapaus- että toimintatutkimus. Tapaustutkimuksena työni kuvaa yhtä juhlaprosessia. Toimintatutkimuksen tunnusmerkit täyttyvät työssäni mm. käytännön hyödyn ja toiminnan kehittämisen muodossa. Yhdessä tekeminen, yhteen tuleminen, laulun ilon tu…

Relationships Between Career Indecision, Search for Work Self-Efficacy, and Psychological Well-Being in Italian Never-Employed Young Adults.

2017

Although different studies have investigated career choices as cognitive acts of decision-making, non-cognitive components also play an important role. The study tries to develop an empirically based model of career decision-making process linking cognitive (search for work self-efficacy - SWSE) and non-cognitive (psychological well-being - PWB) components. In particular, the study investigates, among 148 never-employed Italian young adults, to what extent the relationship between SWSE and career indecision in terms of lack of readiness (LoR) can be explained by their common relationship with PWB. Results highlighted that SWSE is negatively associated with LoR when considered in absence of …

Mediating Effects of Global Negative Effect Expectancies on the Association between Problematic Cannabis Use and Social Anxiety

2017

The relationship between social anxiety and cannabis use among adolescents and young adults is a highly debated topic. In this cross-sectional study, we tested whether cannabis use expectancies mediated the association between social anxiety and cannabis use severity in a sample of 343 young adults (74.3% male) who used cannabis. They completed self-report measures for the screening of problematic cannabis use (Cannabis Use Problems Identification Test) and social anxiety symptoms (Social Interaction Anxiety Scale and Social Phobia Scale). A multiple mediation analysis was used to test whether marijuana effect expectancies mediate social anxiety effect on problematic cannabis use. Social an…

Intolerance of Uncertainty and Risk Perception during the COVID-19 Pandemic: The Mediating Role of Fear of COVID-19

2022

The COVID-19 pandemic, a period of uncertainty and risk, has presented a threat to people’s physical and mental health worldwide. Previous research has shown that pandemic-related uncertainty can contribute to individuals’ psychological distress and coping responses. Therefore, the aim of this study was to investigate the relationship between intolerance of uncertainty and risk perception (i.e., individual’s perceived likelihood of becoming infected both for themselves and people in one’s own country and perceived severity of the infection), and the mediating role of fear of COVID-19. This two-wave longitudinal study (T1 = April 2020; T2 = May 2020) involved 486 youn…

Piedošana un sēru izpausmes sievietēm pēc perinatālā zaudējuma

2021

Šī pētījuma mērķis ir izpētīt saikni starp piedošanas dimensijām (piedošana sev, piedošana citiem un piedošana situācijām), sēru simptomiem un zaudējuma raksturlielumiem sievietēm pēc perinatālā zaudējuma. Kā arī noskaidrot kādā mērā piedošana un zaudējuma raksturlielumi prognozē sēru simptomus. Pētījuma respondentu izlasi veido 440 sievietes, vecumā no 20 līdz 45. gadiem, kur vidējais vecums ir 33,2 gadi. Lai mērītu piedošanu, tika izmantota Hartlenda piedošanas skala (Heartland Forgiveness Scale, Thompson & Snyder, 2003), kuru Latvijā adaptējusi Vendija Balode, 2017. gadā. Traumatisko sēru aptauja (The Traumatic Grief Inventory Self – Report Version, Boelen, & Smid, 2017), kas tika adaptē…
