An Interactive Visualization Tool for Collaborative Construction Logistics Planning—Creating a Sustainable Project Vicinity
- 2022

Tidskriftsartikel (refereegranskat)abstract
- The intensity of urban development is presently high, creating a construction boom. The number of transports per project is a major consideration in urban goods transport and emissions from a project. Presently, the stakeholders take part in a “blame game” in assigning fault for the emissions from construction transport and the disturbances to society in the vicinity of construction sites. Incorporation of logistics into urban planning requires an increased understanding of the interaction between construction transport flows and urban land use, and the inclusion of different stakeholders. The purpose of the study is to support collaborative planning of construction transport in urban planning, and specifically to explore how a planning tool based on interactive visualization could be designed. An action research process has generated two prototypes of an interactive visualization tool for collaborative planning of construction transport. The prototype facilitates a “shared deliberation space” by identifying alternatives and assessing predicted consequences, which supports a collaborative urban planning process. Based on the research conducted, we claim that the responsibility of construction transport planning should be taken by the municipality, i.e., the urban planning and traffic planning functions. © 2022 by the authors.

Störningsfri stad : slutrapport i projektet Visualiserad byggtrafikplanering för en störningsfri stadsutveckling
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Störningsfri stad har kombinerat kunskaper inom Trafikplanering, Visualisering, Bygglogistik, Sensorer och Offentlig planering och styrning. Projektet har letts av Linköpings universitet, Institutionen för Teknik och Naturvetenskap och finansierats av Vinnova, IHS. Projektet har löpt mellan slutet av 2018 och 2021 ut. Projektdeltagare har varit VTI, RISE, Norrköpings kommun, Linköpings kommun, Stockholm stad, Uppsala kommun, Trafikverket Projekt Ostlänken, LE Lundbergs Fastigheter, Wiklunds Åkeri, Wellsec, SanktKors, Byggföretagen, Telenor och Logistikia.Projektet har utvecklat en verktygsprototyp som stöttar kollaborativ planering av byggtrafik och stadsplanering genom att visualisera pågående byggprojekts sammanlagda mängd transporter och var i staden (i form av en kartvy) det uppstår störningar i form av förseningar pga dessa. Verktyget bygger på en MATSim trafikmodell (i nuläget Norrköping) inkluderande både persontransporter (modellerat baserat på mobilnätsdata) och byggtrafik (modellerat baserat på data från bygglogistiklösningar). Med hjälp av verktyget kan olika scenarier för att minska störningarna av byggtransporter testas. För att stötta användandet av verktyget har en kollaborativ planeringsprocess som visar på hur de olika aktörerna involverade i planeringen av byggtransporter och stadsutveckling behöver interagera med varandra utvecklats. Projektet också deltagit i utvecklingen av en sensorbox (partiklar, luftfuktighet, temperatur och ljud) samt slangmätningsmetodik för att öka kunskapen om byggtransporter. Baserat på de resultat som projektet har behovsägarna har påbörjat arbeten med att bättre hantera de störningar som uppstår pga byggprojekt i staden.

Dual roles of heparanase in human carotid plaque calcification
- 2019
-
Ingår i: Atherosclerosis. - : ELSEVIER IRELAND LTD. - 0021-9150 .- 1879-1484. ; 283, s. 127-136

Tidskriftsartikel (refereegranskat)abstract
- Background and aims: Calcification is a hallmark of advanced atherosclerosis and an active process akin to bone remodeling. Heparanase (HPSE) is an endo-beta-glucuronidase, which cleaves glycosaminoglycan chains of heparan sulfate proteoglycans. The role of HPSE is controversial in osteogenesis and bone remodeling while it is unexplored in vascular calcification. Previously, we reported upregulation of HPSE in human carotid endarterectomies from symptomatic patients and showed correlation of HPSE expression with markers of inflammation and increased thrombogenicity. The present aim is to investigate HPSE expression in relation to genes associated with osteogenesis and osteolysis and the effect of elevated HPSE expression on calcification and osteolysis in vitro.Methods: Transcriptomic and immunohistochemical analyses were performed using the Biobank of Karolinska Endarterectomies (BiKE). In vitro calcification and osteolysis were analysed in human carotid smooth muscle cells overexpressing HPSE and bone marrow-derived osteoclasts from HPSE-transgenic mice respectively.Results: HPSE expression correlated primarily with genes coupled to osteoclast differentiation and function in human carotid atheromas. HPSE was expressed in osteoclast-like cells in atherosclerotic lesions, and HPSE-transgenic bone marrow-derived osteoclasts displayed a higher osteolytic activity compared to wild-type cells. Contrarily, human carotid SMCs with an elevated HPSE expression demonstrated markedly increased mineralization upon osteogenic differentiation.Conclusions: We suggest that HPSE may have dual functions in vascular calcification, depending on the stage of the disease and presence of inflammatory cells. While HPSE plausibly enhances mineralization and osteogenic differentiation of vascular smooth muscle cells, it is associated with inflammation-induced osteoclast differentiation and activity in advanced atherosclerotic plaques.

Är barn en del av det planerande kollektivet : En studie om inkludering av barn i planering av kollektivtrafik
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Syftet i denna rapport är att undersöka om och hur barn involveras i den regionala kollektivtrafikplaneringen. De vägledande frågorna för rapporten är följande:Hur har barnkonventionen påverkat arbetet i de regionala kollektivtrafikmyndigheterna?På vilka sätt och i vilka sammanhang inkluderas barn i kollektivtrafikplaneringen?Vilka hinder och möjligheter finns för att involvera barn i kollektivtrafikplaneringen?Projektet inleddes med en litteraturstudie för att kartlägga det rådande internationella och nationella kunskapsläget i frågan om barn i kollektivtrafikplanering och, eftersom studier på specifikt det ämnet var ytterligt få, i samhällsplanering i stort. I ett andra skede av projektet genomfördes dels e-postenkäter och studier av 21 trafikförsörjningsprogram och andra relevanta dokument, dels sju semi-strukturerade intervjuer med tjänstepersoner på sex olika regionala kollektivtrafikmyndigheter.Sammanfattningsvis illustrerar projektet att barnkonventionens implementering i den svenska lagstiftningen inte inneburit större förändringar hos svenska regionala kollektivtrafikmyndigheter i det korta perspektiv som vi studerat. Detta på grund av flertalet orsaker: bristande stöd och vägledning från nationella myndigheter, politiska mål för kollektivtrafiken som inte inkluderar barn, barnperspektiv i planeringen som inte utvecklas till att också inkludera barnen.Projektet har bidragit med ny kunskap om barns mobilitet i relation till kollektivtrafiken.En viktig slutsats är att skoltrafik och linjelagd trafik är tätt sammanbundna ur ett barnsmobilitetsperspektiv och att planeringen av dessa därför också bör vara sammankoppladeför att ett barnrättsperspektiv i kollektivtrafiken på allvar ska kunna uppnås. Detta kräverkommunal och regional samordning, inte bara av trafikplaneringen, utan ocksåsamhällsplanering, så att barnens målpunkter kan vara försörjda av kollektivtrafik,särskild eller linjelagd.

Neurocognitive processes underlying heuristic and normative probability judgments
- 2020

Ingår i: Cognition. - : ELSEVIER. - 0010-0277 .- 1873-7838. ; 196, s. 1-7

Tidskriftsartikel (refereegranskat)abstract
- Judging two events in combination (A&B) as more probable than one of the events (A) is known as a conjunction fallacy. According to dual-process explanations of human judgment and decision making, the fallacy is due to the application of a heuristic, associative cognitive process. Avoiding the fallacy has been suggested to require the recruitment of a separate process that can apply normative rules. We investigated these assumptions using functional magnetic resonance imaging (fMRI) during conjunction tasks. Judgments, whether correct or not, engaged a network of brain regions identical to that engaged during similarity judgments. Avoidance of the conjunction fallacy additionally, and uniquely, involved a fronto-parietal network previously linked to supervisory, analytic control processes. The results lend credibility to the idea that incorrect probability judgments are the result of a representativeness heuristic that requires additional neurocognitive resources to avoid.

Early life swimming pool exposure and asthma onset in children : a case-control study
- 2018
-
Ingår i: Environmental Health. - : BioMed Central (BMC). - 1476-069X. ; 17
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Trichloramine exposure in indoor swimming pools has been suggested to cause asthma in children. We aimed to investigate the risk of asthma onset among children in relation to individual trichloramine exposure.METHODS: A longitudinal nested case-control study of 337 children with asthma (cases) and 633 controls aged 16-17 years was performed within a population-based cohort from The Obstructive Lung Disease in Northern Sweden studies (OLIN). Year of asthma onset and exposure time at different ages were obtained in telephone interviews. Trichloramine concentrations in the pool buildings were measured. Skin prick test results for inhalant allergens were available from previous examinations of the cohort. The risk for asthma was analyzed in relation to the cumulative trichloramine exposure before onset of asthma.RESULTS: Swimming pool exposure in early life was associated with a significantly higher risk of pre-school asthma onset. A dose-response relationship between swimming pool exposure and asthma was indicated in children with asthma onset at 1 year of age. Children who were both sensitized and exposed had a particularly high risk.CONCLUSIONS: Early life exposure to chlorinated swimming pool environments was associated with pre-school asthma onset.

Tidskriftsartikel (refereegranskat)abstract
- Background: By-products of water disinfectants have been suggested to cause asthma, especially in atopic children. However, studies on indoor swimming pool attendance and asthma in children have presented conflicting results. The present study examined the relationship between indoor swimming pool attendance and asthma among sensitized and non-sensitized children aged 11-12 years.Methods: An extended ISAAC questionnaire was sent to the families of all children attending fifth or sixth grade, aged 11-12 years, in two municipalities in Northern Sweden in 2010. A total of 1866 participated (96% of those invited) in the questionnaire study and 1652 (89%) also participated in skin prick testing for 10 standard airborne allergens. Asthma was defined as physician-diagnosed asthma in combination with wheeze or use of asthma medication in the last 12 months. Current swimming pool attendance was reported as >= 1/week or <1/week. Logistic regression models were used for data analysis.Results: The prevalence of current asthma was 8.9% (10.0% of boys; 7.9% of girls) and 14% had attended indoor pools >= 1/week. Children currently attending swimming pools >= 1/week had an increased risk of current asthma. Stratified analyses for allergic sensitization adjusted for sex, parental smoking, parental asthma, and damp housing, showed a statistically significant association for current asthma only among sensitized subjects (OR 95% CI 1.90 1.09-3.32). No association was found between current pool attendance and wheeze, sensitization, rhinitis or eczema.Conclusions: The present study supports the proposed link between indoor swimming pool attendance and asthma in sensitized children.

Dental plaque pH and ureolytic activity in children and adults of a low caries population
- 2014
-
Ingår i: Acta Odontologica Scandinavica. - : Informa UK Limited. - 0001-6357 .- 1502-3850. ; 72:3, s. 194-201

Tidskriftsartikel (refereegranskat)abstract
- Objectives. The aim of this study was to evaluate the plaque pH level and ureolytic activity among children and adults of Karen Hill tribes. Methods. Thirty-four children aged 6-10 years and 46 adults aged 20-38 years were interviewed regarding oral hygiene practices, sucrose intake and betel chewing. Caries experience (DMFT and DT), calculus, bleeding on probing (BoP) and Plaque index (PlI) were registered. Ureolytic activity in supragingival plaque was tested at two interproximal sites (11/12 and 41/42) with the rapid urease test (RUT). Registration of plaque pH was performed at two interproximal sites (15/ 16 and 31/41) before, during and 30 min after rinsing with an urea solution (0.25%). Four interproximal plaque samples (one from each quadrant) per individual were collected to test the bacterial composition using the checkerboard technique. Results. Children and adults had similarly low DMFT and DT values. Children had a higher baseline pH and a higher ureolytic activity in the maxilla (p < 0.05) compared with adults. A significant correlation (r(2) = 0.63) was found between baseline pH and urease activity in the mandibular anterior teeth. Caries-free individuals had a higher baseline pH compared with caries active individuals in the anterior mandibular region (p < 0.01). The microbiological composition was characterized by an anaerobic low acidiogenic microbiota. Conclusions. Dental plaque pH is related to the ureolytic activity, which explains the low acidogenic plaque microflora and the low caries levels in the Karen population.
