    Using wood in multistory apartment construction (WMC) has a climate-positive advantage with buildings acting as long-term carbon storage. Business ecosystem (BE) development around WMC is needed to accelerate the adoption of wooden materials in the conservative construction industry. As the business actors around WMC are essentially different from those using other building materials, new knowledge must be built from the project level. This study uses a qualitative interview approach among actors from three pioneering urban building projects to address their perceptions of building with wood regarding a project-based BE. Based on the thematic analysis, sources of both tangible and intangible value creation were found to arise from building with wood. A higher degree of prefabrication associated with WMC was seen in all projects to influence the reorganization of logistics, enabling faster building processes and lean material use. No strong sustainability-driven culture could be identified in any of the projects. Results further flag the sensitivity and importance of management and coordination skills in targeting improvements of the construction business based on WMC. In the bigger picture, there is still room for further research at regional and global level on business model changes in building with this renewable and recyclable material.Peer reviewe

    The study evaluated the psychometric properties of Finnish versions of the Social Phobia and Anxiety Inventory for Children (SPAI-C) and the Social Anxiety Scale for Children-Revised (SASC-R). 352 students (M = 12.2 years) participated in the study and completed the SPAI-C and SASC-R. In addition, 68 participants (M = 12.2 years) and their parents were interviewed with the Schedule for Affective Disorders and Schizophrenia for School Aged Children (K-SADS-PL). The SPAI-C was more sensitive for identifying youth meeting criteria for social phobia (SP), whereas the SASC-R demonstrated greater specificity. The youth in this sample had lower mean total scores on the self-report questionnaires than did those in the original validitation studies of the SPAI-C and SASC-R conducted in America. These findings question whether cross-cultural differences in the expression of SP influence the clinical cut-off scores used in translated versions of social anxiety questionnaires

    Wooden multi-storey construction market development - systematic literature review within a global scope with insights on the Nordic region

    Climate change sets high pressures on the construction industry to decrease greenhouse gas emissions. Due to the carbon storage properties and potential to use renewable resources efficiently, wooden multi-storey construction (WMC) is an interesting alternative for the construction industry to enhance sustainable development combined with the aesthetic and well-being benefits of wood perceived among many consumers. For forest industry firms, industrial wood construction is a possibility to seek for business opportunities and bring socio-economic benefits for local economies. Despite positive drivers, WMC still remains a niche even in the forest-rich countries.The purpose of our study is to add understanding on the WMC market development by conducting a systematic literature analysis on international peer-reviewed studies from the past 20 years. Our special focus is on the role of WMC in the housing markets studied from the perspectives of the demand, supply and local governance factors. As specific aims, we 1) synthesize the key barriers and enabling factors for the WMC market growth; 2) identify the actors addressed in the existing studies connected to the WMC market development, and 3) summarize research methods and analytical approaches used in the previous studies. As a systematic method to make literature searches in Web of Science and Scopus for years 2000-2020, we employed PRISMA guidelines. By using pre-determined keywords, our searches resulted in a sample of 696 articles, of which 42 full articles were after selection procedure included in-depth content analysis. Our results showed cost-efficiency gains from industrialized prefabrication and perceived sustainability benefits by consumers and architects enabled a WMC market diffusion. The lack of experiences on the WMC, and path dependencies to use concrete and steel continue to be key barriers for increased WMC. Although our research scope was the global WMC market development, most of the literature concerned the Nordic region. The key actors covered in the literature were businesses (e.g., contractors, manufacturers and architects) involved in the wood construction value-chains, while residents and actors in the local governance were seldomly addressed. Currently, case studies, the use of qualitative data sets and focus on the Nordic region dominate the literature. This hinders the generalizability of findings in different regional contexts. In the future, more research is needed on how sustainability-driven wood construction value-chains are successfully shaping up in different geographical regions, and how they could challenge the dominant concrete-based construction regime.Peer reviewe

    When does the Autism Spectrum Screening Questionnaire (ASSQ) predict autism spectrum disorders in primary school-aged children?

    Full text link
    The aims of this study were, firstly, to study the association between parents’ and teachers’ ratings for the Finnish version of the Autism Spectrum Screening Questionnaire (ASSQ), secondly, to find out whether the original cut-off scores of the ASSQ identify primary school-aged children with Asperger syndrome (AS) or autism by using the Finnish ASSQ, and thirdly, to evaluate the validity of the ASSQ. Parents and/or teachers of higher-functioning (full-scale intelligence quotient ≥ 50) 8-year-old total population school children (n = 4,408) and 7–12-year-old outpatients with AS/autism (n = 47) completed the Finnish version of the ASSQ. Agreement between informants was slight. In the whole total population, low positive correlation was found between parents’ and teachers’ ratings, while in the sample of high-scoring children the correlation turned out to be negative. A cut-off of 30 for parents’ and teacher's summed score and 22 for teachers’ single score is recommended. A valid cut-off for parents’ single score could not been estimated. The clinicians are reminded that the ASSQ is a screening instrument, not a diagnosing instrument. The importance of using both parents’ and teachers’ ratings for screening in clinical settings is underlined

    Familiality of Quantitative Autism Traits

    Autistic traits exist along a continuum that extends into social functioning in the general population, and they aggregate in the family members of children with autism spectrum disorder (ASD). Quantitative measures are therefore essential when investigating the patterns of familiality of these traits. Prior studies have suggested differential inheritance patterns of autistic traits that depend on the cognitive level of the child with ASD as well as the family type.Our goal was to examine the family patterns of quantitative autism traits (QAT) in a group of simplex autism families of high-functioning children with ASD.We used the Social Responsiveness Scale (SRS) to evaluate QAT in 47 ASD families and 46 control families. SRS assessments (parental/spousal evaluations) were collected for the children with ASD, their siblings, and their parents as well as for the control children and their parents.The SRS was able to distinguish individuals with ASD from the control children and from their unaffected siblings. Significant group differences were also found when comparing the fathers of ASD families to control fathers and when comparing the brothers of individuals with ASD to control boys, with male members of ASD families having higher SRS scores. Gender differences were observed in the group of siblings of children with ASD and the group of parents of children with ASD, with males having higher scores than females. In ASD families, a positive trend between child and father QAT was found, whereas mothers' scores were not associated with child outcomes. By contrast, in control families, mothers' QAT correlated more strongly with child QAT.Autistic traits aggregate in the fathers and brothers of children with ASD in simplex autism families. The QAT levels of the family members should be taken into consideration when planning the rehabilitation of the child or adolescent with ASD and when designing family interventions

    Resting state fMRI reveals a default mode dissociation between retrosplenial and medial prefrontal subnetworks in ASD despite motion scrubbing

    In resting state functional magnetic resonance imaging (fMRI) studies of autism spectrum disorders (ASDs) decreased frontal-posterior functional connectivity is a persistent finding. However, the picture of the default mode network (DMN) hypoconnectivity remains incomplete. In addition, the functional connectivity analyses have been shown to be susceptible even to subtle motion. DMN hypoconnectivity in ASD has been specifically called for re-evaluation with stringent motion correction, which we aimed to conduct by so-called scrubbing. A rich set of default mode subnetworks can be obtained with high dimensional group independent component analysis (ICA) which can potentially provide more detailed view of the connectivity alterations. We compared the DMN connectivity in high-functioning adolescents with ASDs to typically developing controls using ICA dual-regression with decompositions from typical to high dimensionality. Dual-regression analysis within DMN subnetworks did not reveal alterations but connectivity between anterior and posterior DMN subnetworks was decreased in ASD. The results were very similar with and without motion scrubbing thus indicating the efficacy of the conventional motion correction methods combined with ICA dual-regression. Specific dissociation between DMN subnetworks was revealed on high ICA dimensionality, where networks centered at the medial prefrontal cortex and retrosplenial cortex showed weakened coupling in adolescents with ASDs compared to typically developing control participants. Generally the results speak for disruption in the anterior-posterior DMN interplay on the network level whereas local functional connectivity in DMN seems relatively unaltered

Kustantajalle ilmoitettu ja pyydetty korjausta.Abstract Background: Twin and family studies have indicated a strong genetic component in autism spectrum disorders, and genetic studies have revealed highly heterogeneous risk factors. The range and severity of the symptom presentation also vary in the spectrum. Thus, symptom-based phenotypes are putatively more closely related to the underlying biology of autism than the end-state diagnosis. Methods: We performed principal component analysis on Autism Diagnostic Interview-Revised algorithm for 117 Finnish families and 594 families from the Autism Genetic Research Exchange (AGRE). The resulting continuous component scores were used as quantitative phenotypes in family-based association analysis. In addition, K-means clustering was performed to cluster and visualize the results of the PCA. Unaffected siblings were included in the study. Results: The components were interpreted as Social Component (SC), communication component and Restricted and Stereotyped Behavior Component (RSBC). K-means clustering showed that, especially in SC, the range of the symptom severity was increased by the siblings. The association of neuroligin 1 with SC was increased, compared to a previous study where only the end-state diagnosis was used. In RSBC, the range of the symptom severity of siblings overlapped greatly with that of patients, which could explain why no association of reelin was found in previous studies in which only the end-state diagnosis was used, but a significant association of reelin with RSBC was now found in the Finnish families (Bonferroni-corrected p=0.029 for rs362644). Although, the Finnish sample is isolated and genetically very homogeneous, compared to the heterogeneous background of AGRE families, many single-nucleotide polymorphisms in reelin, showed modest association with RSBC in the AGRE sample, too. Conclusions: This study demonstrates how the quantitative phenotypes can affect the association analyses, and yields further support to the use of siblings in the study of complex neuropsychiatric disorders.Peer reviewe

    Pienimolekyylisen hepariinin pistosohje potilaalle : Potilasohjeen laatiminen

    Get PDF
    Opinnäytetyömme oli projektityö, jonka tarkoituksena oli tehdä potilasohje pienimolekyylisen hepariinin pistämisestä. Oulun yliopistollisen sairaalan kirurginen vastuualue tilasi työn, koska heillä oli käytössään vain tuotemerkkikohtaisia ohjeita ja yleisohje puuttui. Pienimolekyylinen hepariini on veren hyytymistä estävä lääkeaine, jota käytetään etenkin kirurgisilla potilailla estämään laskimotukosten syntymistä. Potilaiden sairaalassaoloajan lyhenemisen myötä kotona tapahtuva pienimolekyylisen hepariinin pistoshoito on merkittävästi lisääntynyt. Potilas tarvitsee hoidon onnistumiseksi hyvää ohjausta ja ohjauksen tueksi kirjallisen pistosohjeen mukaan kotiinsa. Potilasohjeemme tulee sähköiseen muotoon Oulun yliopistollisen sairaalan intranettiin, josta se on helposti tulostettavissa potilaille.The purpose of this thesis was to make a patient guide for the patients, who need a low-molecular-weight heparin (LMWH)injection.Low-molecular-weight heparin is a medicinal substance which prevents blood from clotting, for example after big operations. Patients need LMWH treatments often after their hospital stay. Patients need guidance to be able to give injections to themselves at home. The patient guide was made in cooperation with the School of Health and Social Care at Oulu University of Applied Sciences and Oulu University Hospital
