Vascularity, perfusion rate and local tissue oxygenation of tumors derived from ras-transformed fibroblasts.
2007
Tumors derived from ras-transformed rat fibroblasts were investigated in order to gain insight into possible interrelationships between oncogenic transformations and therapeutically relevant parameters of the metabolic micromilieu of solid tumors in vivo. Tumors grew in nude mice after injection of in vitro-passaged cells. Growth rates, early stages of angiogenesis, perfusion and tissue oxygenation were assessed. Compared with the parental cell line, both ras transformants grew very rapidly and exhibited an early onset of angiogenesis. Perfusion rates of one ras-transformed tumor line were similar to those of the parental tumors whereas reduced flow values were detected in tumors of the oth…
Kinetic modeling of ion conduction in KcsA potassium channel.
2005
KcsA constitutes a potassium channel of known structure that shows both high conduction rates and selectivity among monovalent cations. A kinetic model for ion conduction through this channel that assumes rapid ion transport within the filter has recently been presented by Nelson. In a recent, brief communication, we used the model to provide preliminary explanations to the experimental current-voltage J-V and conductance-concentration g-S curves obtained for a series of monovalent ions (K(+),Tl(+), and Rb(+)). We did not assume rapid ion transport in the calculations, since ion transport within the selectivity filter could be rate limiting for ions other than native K(+). This previous wor…
Tracing anthropogenic thallium in soil using stable isotope compositions.
2014
Thallium stable isotope data are used in this study, for the first time, to apportion Tl contamination in soils. In the late 1970s, a cement plant near Lengerich, Germany, emitted cement kiln dust (CKD) with high Tl contents, due to cocombustion of Tl-enriched pyrite roasting waste. Locally contaminated soil profiles were obtained down to 1 m depth and the samples are in accord with a binary mixing relationship in a diagram of Tl isotope compositions (expressed as e(205)Tl, the deviation of the (205)Tl/(203)Tl ratio of a sample from the NIST SRM 997 Tl isotope standard in parts per 10(4)) versus 1/[Tl]. The inferred mixing endmembers are the geogenic background, as defined by isotopically l…
Future reform of Chinese elite sport management system : perspective of sport events
2010
The primary intention of this study is to present and evaluate the elite sport management system in China and to predict the trend of future reformation in Chinese elite sport management system. In addition, this study attempts to enhance the understanding to Chinese sport management system. The literature review plays an important part in the study background of this research, and there are four kinds of theoretical method were used in the research and analysis of this study. The Delphi Method and Gordon Method are used for the group interview and the Creswell Model is a way to collect useful material from the method of literature review. In addition the scale used in sport event spectator…
”Meillä ei ole politiikkaa valtionavustuksissa!”
2021
Valtionavustustoiminta on olennainen osa suomalaista yhteiskuntapolitiikkaa ja valtionhallinnon ohjausjärjestelmää. Avustamista toimeenpanevat ministeriöt, tulosohjatut virastot sekä muut asiantuntijaorganisaatiot. Artikkelimme tutkii kulttuurihallinnon virkakunnan vallankäyttöä opetus- ja kulttuuriministeriön (OKM) valtionavustuspolitiikassa. Ymmärrämme kulttuurihallinnon ohjausvälineineen merkittävänä valtaa käyttävänä organisaatiorakenteena. Tarkastelu pohjautuu arviointitutkimukseen OKM:n tulosohjaaman asiantuntijaviraston Taiteen edistämiskeskuksen (Taike) valtionavustusprosessista. Artikkelimme on tapaustutkimus, jossa kuvaamme kulttuuripolitiikan toimeenpanorakent…
Exploring citizens' legitimacy judgments about governmental refugee policies
2017
Tämän tutkimuksen tavoitteena on saada tietoa siitä, miten nuoret, korkeakoulutetut suomalaiset muodostavat legitimiteettiarvioitaan Suomen hallituksen pakolaispolitiikasta. Tutkimus on osa kansainvälistä tutkimushanketta, joka toteutettiin Suomessa, Saksassa ja Espanjassa. Työn teoreettinen viitekehys on legitimiteettiteoriassa ja erityisesti Suchmanin (1995) neljässä legitimiteetin alatyypissä. Tutkimusmetodeina käytetään fokusryhmätutkimusta, Q-metodia ja teoriaohjaavaa sisällönanalyysia. Tulokset osoittavat luottamusta hallituksen toimia kohtaan pakolaiskriisissä. Tämän tutkimuksen perusteella Suomen hallitukselle myönnetään legitimiteetti sen pohjalta, miten hallit…
An introduction to knowledge computing
2014
This paper deals with the challenges related to self-management and evolution of massive knowledge collections. We can assume that a self-managed knowledge graph needs a kind of a hybrid of: an explicit declarative self-knowledge (as knowledge about own properties and capabilities) and an explicit procedural self-knowledge (as knowledge on how to utilize own properties and the capabilities for the self-management).We offer an extension to a traditional RDF model of describing knowledge graphs according to the Semantic Web standards so that it will also allow to a knowledge entity to autonomously perform or query from remote services different computational executions needed. We also introdu…
Teacher coping profiles in relation to teacher well-being : a mixed method approach
2021
The aim was to investigate teachers’ coping profiles and their relations to teacher well-being. Questionnaire data was collected from 107 Finnish teachers. Theory-driven content analysis of teachers’ responses revealed three coping categories: problem-focused, emotion-focused and mixed problem- and emotion-focused. Next, teachers were categorized into four coping profiles by using latent profile analysis: Low-coping users (21%), Problem-focused-coping users (15%), High-coping users (12%) and Emotion-focused-coping users (52%). Low-coping-user teachers reported less stress and fewer depressive symptoms and sleep problems compared to Emotion-focused-coping users. Using a compact amount of cop…
Identifying Coping Profiles and Profile Differences in Role Engagement and Subjective Well-Being
2014
Coping strategies are not necessarily mutually exclusive and can be used simultaneously, a fact which has rarely been examined in coping research. We examined what kinds of coping profiles could be found in data concerning Finnish health care and service employees (n = 2756). We also studied whether role engagement (family-to-work-enrichment, work-to-family-enrichment, emotional energy at work, and work engagement) and subjective well-being (life, parental, and marital satisfaction, and psychological distress) differ between coping profiles. The data were analyzed through latent profile (LPA) and covariance analyses (Ancovas). LPA revealed seven distinct coping profiles: two active groups,…
Viral tunes:changes in musical behaviours and interest in coronamusic predict socio-emotional coping during COVID-19 lockdown
2021
AbstractBeyond immediate health risks, the COVID-19 pandemic poses a variety of stressors, which may require expensive or unavailable strategies during a pandemic (e.g., therapy, socialising). Here, we asked whether musical engagement is an effective strategy for socio-emotional coping. During the first lockdown period (April–May 2020), we surveyed changes in music listening and making behaviours of over 5000 people, with representative samples from three continents. More than half of respondents reported engaging with music to cope. People experiencing increased negative emotions used music for solitary emotional regulation, whereas people experiencing increased positive emotions used musi…
