Charge breeding time investigations of electron cyclotron resonance charge breeders
2018
To qualify electron cyclotron resonance charge breeders, the method that is traditionally used to evaluate the charge breeding time consists in generating a rising edge of the injected beam current and measuring the time in which the extracted multicharged ion beam reaches 90% of its final current. It is demonstrated in the present paper that charge breeding times can be more accurately measured by injecting short pulses of 1 + ions and recording the time resolved responses of N + ions. This method is used to probe the effect of the 1 + ion accumulation in the plasma known to disturb the buffer gas plasma equilibrium and is a step further in understanding the large discrepancies reported in…
Dispersion from Cα or NH: 4D experiments for backbone resonance assignment of intrinsically disordered proteins
2020
AbstractResonance assignment of intrinsically disordered proteins is remarkably challenging due to scant chemical shift dispersion arising from conformational heterogeneity. The challenge is even greater if repeating segments are present in the amino acid sequence. To forward unambiguous resonance assignment of intrinsically disordered proteins, we present iHACANCO, HACACON and (HACA)CONCAHA, three Hα-detected 4D experiments with Cα as an additional dimension. In addition, we present (HACA)CON(CA)NH and (HACA)N(CA)CONH, new 4D Hα-start, HN-detect experiments which have two NH dimensions to enhance peak dispersion in a sequential walk through C′, NH and HN, and provide more accurate NH/HN ch…

Sanailua, suunsoittoa ja syrjintää : Nuorten kokemuksia pelikäytöksestä
2022
Artikkelissa tarkastellaan laadullisen kyselyaineiston (N=180) avulla suomenkielisten, 15–25-vuotiaiden nuorten kokemuksia pelikäytöksestä digitaalisten pelien parissa. Teema-analyysin avulla rakennetut teemat valottavat epäasiallisen pelikäytöksen syitä ja seurauksia, kilpailullisten pelien suunsoittokulttuuria, pelikulttuureissa esiintyvää rakenteellista syrjintää, sekä myönteistä pelikäytöstä. Pelikäytös näyttäytyy artikkelissa monipuolisena ja monimutkaisena kokonaisuutena, johon vaikuttavat niin yksilöiden ominaisuudet ja mieltymykset kuin pelikulttuurien ja yhteiskunnan rakenteet. Artikkelin lopussa esitetään ehdotuksia keinoista vähentää asiatonta pelikäytöstä. This article explores …
Dance on cortex: enhanced theta synchrony in experts when watching a dance piece
2018
When watching performing arts, a wide and complex network of brain processes emerge. These processes can be shaped by professional expertise. When compared to laymen, dancers have enhanced processes in observation of short dance movement and listening to music. But how do the cortical processes differ in musicians and dancers when watching an audio-visual dance performance? In our study, we presented the participants long excerpts from the contemporary dance choreography of Carmen. During multimodal movement of a dancer, theta phase synchrony over the fronto-central electrodes was stronger in dancers when compared to musicians and laymen. In addition, alpha synchrony was decreased in all gr…
Enhancing the efficacy of integrative improvisational music therapy in the treatment of depression : study protocol for a randomised controlled trial
2019
Abstract Background Depression is among the leading causes of disability worldwide. Not all people with depression respond adequately to standard treatments. An innovative therapy that has shown promising results in controlled trials is music therapy. Based on a previous trial that suggested beneficial effects of integrative improvisational music therapy (IIMT) on short and medium-term depression symptoms as well as anxiety and functioning, this trial aims to determine potential mechanisms of and improvements in its effects by examining specific variations of IIMT. Methods/design A 2 × 2 factorial randomised controlled trial will be carried out at a single centre in Finland involving 68 adu…
"Sitä vaan hengitetään, joskus yksin ja joskus yhdessä" : tapaustutkimus sosiaalisen fobian tuomista haasteista terapeuttisen yhteistyösuhteen muodos…
2014
Tämän pro gradu -tutkielman tarkoituksena on selvittää sosiaalisen fobian vaikutusta terapeuttisen yhteistyösuhteen rakentumiseen yhden kokonaisen terapiaprosessin aikana. Lisäksi tutkimuksen tarkoituksena on kuvata asiakkaan ja terapeutin kokemia yhteistyösuhteeseen liittyviä haasteita sekä tarkastella niitä Bordinin (1979) yhteistyösuhteen teorian valossa. Aineistomme koostuu yhdestä Jyväskylän yliopiston opetus- ja tutkimusklinikalle sosiaalisen fobian vuoksi hakeutuneen asiakkaan koko 54 istuntoa kattavasta terapiaprosessista. Tutkielma on luonteeltaan laadullinen tapaustutkimus, jonka analyysimenetelmänä käytämme tapaustutkimusten ja pienten aineistojen tutkimiseen kehitettyä tulkitsev…
Loss of density-dependence and incomplete control by dominant breeders in a territorial species with density outbreaks
2011
Abstract Background A territory as a prerequisite for breeding limits the maximum number of breeders in a given area, and thus lowers the proportion of breeders if population size increases. However, some territorially breeding animals can have dramatic density fluctuations and little is known about the change from density-dependent processes to density-independence of breeding during a population increase or an outbreak. We suggest that territoriality, breeding suppression and its break-down can be understood with an incomplete-control model, developed for social breeders and social suppression. Results We studied density dependence in an arvicoline species, the bank vole, known as a terri…
