Management diversity begets biodiversity in production forest landscapes
2022
How to manage forest for biodiversity conservation is an ongoing debate. We argue that maximizing biodiversity in managed forest landscapes requires a diversity of forest management regimes in space and time. This will generate high levels of habitat heterogeneity at a landscape scale, which in turn will support various groups of forest species. Based on concepts from landscape ecology, we formulate five hypotheses on how management diversity, i.e. combining various management approaches can benefit overall biodiversity across a production forest landscape. First, management diversity will increase habitat diversity and, therefore, beta diversity (the habitat diversity hypothesis). Second, …
F-centru un irīdija piemaisījumu aprēķini no pirmajiem principiem gallija oksīdā polimorfos
2022
Pēdējā laikā gallijā oksīds (Ga2O3) kļuva par vienu no visaktīvāk pētāmiem materiāliem. Iemesls ir tā konkurētspējīgās elektroniskās īpašības kā, piemēram, plata aizliegtā zona, augsts caursites spriegums, viegla lādiņnesēju koncentrāciju kontrole un augsta termiskā stabilitāte. Šo īpašību dēļ, Ga2O3 ir potenciāls kandidāts uz pielietojumiem augstas jaudas elektroniskās ierīcēs. Parasti Ga2O3 kristālus audzē izmantojot Čohralska metodi, kurā tiek izmantots irīdija (Ir) tīģelis. Šī iemesla dēļ Ir ir bieži klāt Ga2O3 kristālos kā netīšs dopants. Šajā darbā ir pētītā Ir aizvietošanas defektu, ka arī F-centru ietekme uz Ga2O3 elektronisku struktūru dažādās kristāliskās fāzēs, izmantojot blīvuma…

Physical activity intention and attendance behaviour in Finnish youth with cerebral palsy – results from a physical activity intervention: an applica…
2021
Physical activity is associated with better health in individuals with cerebral palsy (CP). Numerous physical activity interventions have been designed to promote physical activity among youth with CP. No previous studies have explored the factors contributing to the intention to participate and predicting attendance behaviour for these interventions. Using theory of planned behaviour (TPB), this study explored the prediction of physical activity intention and attendance behaviour in a physical activity intervention aiming to promote physical activity in a sample of young individuals with CP. Males with CP aged 9–21 years were asked to complete measures of attitude, subjective norms, percei…
Wearable electromyography recordings during daily life activities in children with cerebral palsy.
2020
To test whether wearable textile electromyography (EMG) recording systems may detect differences in muscle activity levels during daily activities between children with cerebral palsy (CP) and age-matched typically developing children.Wearable textile EMG recording systems were used to obtain leg muscle activity in 10 children with spastic CP (four females, six males; mean age 9y 6mo, standard deviation [SD] 2y 4mo, range: 6-13y; Gross Motor Function Classification System [GMFCS] level I and II) and 11 typically developing children (four females, seven males; mean age 9y 9mo, SD 1y 11mo, 7-12y) at rest and while performing seven daily activities.Children with CP showed significantly lower a…
A test of the effort equalization hypothesis in children with cerebral palsy who have an asymmetric gait.
2022
Healthy people can walk nearly effortlessly thanks to their instinctively adaptive gait patterns that tend to minimize metabolic energy consumption. However, the economy of gait is severely impaired in many neurological disorders such as stroke or cerebral palsy (CP). Moreover, self-selected asymmetry of impaired gait does not seem to unequivocally coincide with the minimal energy cost, suggesting the presence of other adaptive origins. Here, we used hemiparetic CP gait as a model to test the hypothesis that pathological asymmetric gait patterns are chosen to equalize the relative muscle efforts between the affected and unaffected limbs. We determined the relative muscle efforts for the ank…
P 042 - Gait complexity quantified using inertial measurement units in children with cerebral palsy
2018
Children with cerebral palsy (CP) have various gait impairments, and consequently their gait is less stable compared to typically developed (TD) controls. Gait kinematics are also affected more in CP than TD by concurrent dual and cognitive tasks. Inertial measurement units (IMU) provide efficient tool to quantify gait stability, but the practical value of IMU based gait assessment has not been tested in children with CP. nonPeerReviewed
The gait is less stable in children with cerebral palsy in normal and dual-task gait compared to typically developed peers
2021
There is limited evidence about gait stability and its alteration by concurrent motor and cognitive tasks in children with cerebral palsy (CP). We examined gait stability and how it is altered by constrained cognitive or motor task in CP and their typically developed (TD) controls. Gait kinematics were recorded using inertial-measurement units (IMU) from 18 patients with hemiplegia (13.5 +/- 2.4 years), 12 with diplegia (13.0 +/- 2.1 years), and 31 TD controls (13.5 +/- 2.2 years) during unconstrained gait, and motor (carrying a tray) and cognitive (word naming) task constrained gait at preferred speed (similar to 400 steps/task). Step duration, its standard deviation and refined-compound-m…
P 042 - Gait complexity quantified using inertial measurement units in children with cerebral palsy
2018
Abstract Children with cerebral palsy (CP) have gait impairments, and their gait is affected by concurrent tasks. We used inertial measurement units (IMU) to quantify CP-related gait complexity alterations, and identify effects of dual tasks on gait variability from 12 children with CP and 23 typically developed (TD) controls. The data were collected for normal and dual-tasks (motor; carrying a tray, cognitive; word naming) during walking. Step duration and adjusted multiscale entropy (MSE) index were computed. In overall, children with CP had shorter step duration and greater gait complexity than TD. Gait complexity was higher in vertical direction during the cognitive than normal and moto…
"Nykyään sitä on oppinut arvostaa" : nuorten, joilla on CP- vamma, kokemuksia pitkäaikaisesta fysioterapiasta
2012
Pro gradu- tutkimukseni tarkoituksena on ymmärtää ja kuvata nuorten, joilla on CP- vamma, kokemuksia pitkäaikaisesta fysioterapiasta fenomenologis- hermeneuttisen tutkimusasetelman kautta. Tutkimus liittyy laajempaan Jyväskylän yliopiston koordinoimaan Potilasohjaus fysioterapiassa – projektiin ja sillä on tutkimuslupa HUS:n eettiseltä toimikunnalta. Tutkimukseen osallistui 10 nuorta, joilla on ollut fysioterapiaa pienestä lapsesta lähtien, 16-22 -vuotta. Aineisto kerättiin avoimien yksilöllisten haastattelujen avulla ja analysoitiin Spiegelbergin (1982) ja Laineen (2010) aineistoanalyysimenetelmän kautta. Tutkimukseen osallistuneiden nuorten merkityskokonaisuuksina ilmenivät: fysioterapia …
