ADHD ja sen tuki- ja hoitokeinot alakoulussa
Tiivistelmä. Aktiivisuuden ja tarkkaavuuden häiriö ADHD on neuropsykiatrinen häiriö, jonka keskeisiä oireita ovat pitkäkestoiset vaikeudet säädellä aktiivisuutta, tarkkaavuutta ja impulsiivisuutta. ADHD vaikuttaa yksilöön useilla eri elämänalueilla. Koulu on lapsen keskeinen elämänalue ja ADHD tuottaakin usein merkittäviä haasteita koulunkäyntiin ja koulussa tapahtuvaan sosiaaliseen kanssakäymiseen. Opettajilla ja muilla eri alojen ammattilaisilla on mahdollisuus erilaisilla hoito- ja tukimuodoilla vähentää ADHD:lle tyypillistä oirekuvaa ja siitä johtuvia haasteita.
Tässä kandidaatin tutkielmassa tarkastelen millaisia haasteita ADHD-oireiset oppilaat kohtaavat alakoulussa. Tavoitteenani on tuoda esiin keskeisiä tuki- ja hoitokeinoja, joilla ADHD:lle tyypillistä oirekuvaa voidaan helpottaa. Tutkielmani on kirjallisuuskatsaus, jonka olen luonut aikaisempien tutkimusten, eri tieteenalojen kirjallisuuden ja vertaisarvioitujen artikkeleiden pohjalta.
Tutkielmani perusteella ADHD näkyy oppilailla keskivertoa alhaisempina oppimistuloksina, vaikeutena keskittyä tunneilla ja haasteina kaverisuhteissa. Opettajalla on mahdollisuus muovata luokan arkea, oppimisympäristöä ja opettamista ADHD-oireiselle oppilaalle edulliseksi niin, että keskeinen oirekuva sekä oppiminen helpottuu. Tiiviit ja johdonmukaiset interventiot ja psykososiaaliset hoitomuodot ovat toimiviksi todettuja hoito- ja tukitoimia ADHD:lle mahdollisen lääkehoidon lisäksi. Tutkielmani osoitti, että tukitoimissa keskeisiä teemoja ovat moniammatillinen yhteistyö, kannustaminen ja johdonmukaisuus. Kaikessa tukemisessa keskeistä on yksilöllisyyden huomioiminen sekä positiivinen ja välittävä vuorovaikutus.
ADHD and its support and treatment methods in primary school. Abstract. Attention deficit hyperactivity disorder is a neuropsychiatric disorder, which main symptoms are long-term difficulties in regulating activity, alertness, and impulsivity. ADHD affects an individual in many different areas of life. School is a key area of a child’s life and ADHD does present many remarkable social challenges to school attendance and social interaction at school. Teachers and other professionals in different fields have the opportunity to reduce the symptoms and challenges of ADHD through a variety of treatment and support methods.
In this bachelor’s thesis, I will review what kind of difficulties students with ADHD face in elementary school. My goal is to bring up the essential support and treatment methods that can reduce the typical range of symptoms. My thesis is a literature review that I have written based on previous studies, literature from different sciences, and peer-reviewed articles.
Based on my study, ADHD occurs in students as lower-than-average learning outcomes, difficulties in focusing in class, and challenges in friend relationships. The teacher has the opportunity to shape the classroom’s everyday life, learning environment, and teaching of the class for the benefit of a student with ADHD so that the central range of symptoms and learning are facilitated. Concise and consistent interventions and psychosocial forms of treatments are proven to be an effective treatment and support options for ADHD in addition to possible medical treatment. Consideration of individuality along with positive and caring interaction is essential in all forms of support

Supermagnetosonic jets behind a collisionless quasi-parallel shock
The downstream region of a collisionless quasi-parallel shock is structured
containing bulk flows with high kinetic energy density from a previously
unidentified source. We present Cluster multi-spacecraft measurements of this
type of supermagnetosonic jet as well as of a weak secondary shock front within
the sheath, that allow us to propose the following generation mechanism for the
jets: The local curvature variations inherent to quasi-parallel shocks can
create fast, deflected jets accompanied by density variations in the downstream
region. If the speed of the jet is super(magneto)sonic in the reference frame
of the obstacle, a second shock front forms in the sheath closer to the
obstacle. Our results can be applied to collisionless quasi-parallel shocks in
many plasma environments.Comment: accepted to Phys. Rev. Lett. (Nov 5, 2009
Linking tree growth rate, damage repair, and susceptibility to a genus-specific pest infestation
Pest preference and subsequent susceptibility of a host individual is likely related to previous growth patterns in that host. Emerald ash borer (Agrilus planipennis Fairmaire) is a pestiferous beetle introduced to North America from Asia. While all species of ash are susceptible to attack, some individual trees appear to survive infestation. We selected ash trees in southeastern Michigan, collected cores and categorized trees as high tolerance to emerald ash borer attack (high overall health, low crown dieback), low tolerance (low overall health, high crown dieback) and intermediate tolerance (in-between the other categories). We artificially wounded trees and measured wound closure after 3 years. Ring width indices were not correlated between high and low tolerance trees. Regression slopes comparing growth and years were significantly different between the three tolerance categories, with high tolerance trees having the steepest slope. Wound closure was greatest in high tolerance trees. High tolerance trees demonstrating more rapid (steeper regression slope), consistent (lower variance), and effective (greater wound closure) growth. Those vigorously growing trees likely had more capacity to repair damage caused by emerald ash borer, leading to healthier trees in our categorization. Linking previous host growth patterns to health may have implications related to identifying individual trees potentially tolerant to attack
Substrate-specific transcription of the enigmatic GH61 family of the pathogenic white-rot fungus Heterobasidion irregulare during growth on lignocellulose
The GH61 represents the most enigmatic Glycoside Hydrolase family (GH) regarding enzymatic activity and importance in cellulose degradation. Heterobasidion irregulare is a necrotizing pathogen and white-rot fungus that causes enormous damages in conifer forests. The genome of H. irregulare allowed identification of ten HiGH61 genes. qRT-PCR analysis separate the HiGH61 members into two groups; one that show up regulation on lignocellulosic substrates (HiGH61A, HiGH61B, HiGH61D, HiGH61G, HiGH61H, and HiGH61I) and a second showing either down-regulation or constitutive expression (HiGH61C, HiGH61E, HiGH61F, and HiGH61J). HiGH61H showed up to 17,000-fold increase on spruce heartwood suggesting a pivotal role in cellulose decomposition during saprotrophic growth. Sequence analysis of these genes reveals that all GH61s except HiGH61G possess the conserved metal-binding motif essential for activity. The sequences also divide into groups having either an insert near the N terminus or an insert near the second catalytic histidine, which may represent extensions of the substrate-binding surface. Three of the HiGH61s encode cellulose-binding modules (CBM1). Interestingly, HiGH61H and HiGH61I having CBM1s are up-regulated on pure cellulose. There was a common substrate-specific induction patterns of the HiGH61s with several reference cellulolytic and hemicellulolytic GHs, this taken together with their low transcript levels on media lacking lignocellulose, reflect the concerted nature of cell wall polymer degradation.
