Subjective health literacy among school-aged children
2018
Purpose The purpose of this paper is to explore Finnish adolescents’ subjective health literacy (HL) in association to school achievement, learning difficulties, educational aspirations, and family affluence. Design/methodology/approach Nationally representative data were collected in Finland as a part of the international Health Behaviour in School-aged Children study. The respondents consisted in total of 3,833 adolescents (7th and 9th graders) from 359 schools. The Health Literacy for School-aged Children instrument was applied to measure adolescents’ subjective HL, while the Family Affluence Scale was used to measure adolescents’ socioeconomic status. Information was gathered on school…
Mast cells as protectors of health.
2019
Mast cells (MCs), which are well known for their effector functions in T(H)2-skewed allergic and also autoimmune inflammation, have become increasingly acknowledged for their role in protection of health. It is now clear that they are also key modulators of immune responses at interface organs, such as the skin or gut. MCs can prime tissues for adequate inflammatory responses and cooperate with dendritic cells in T-cell activation. They also regulate harmful immune responses in trauma and help to successfully orchestrate pregnancy. This review focuses on the beneficial effects of MCs on tissue homeostasis and elimination of toxins or venoms. MCs can enhance pathogen clearance in many bacter…
Metabolic Changes in Tumor Microenvironment: How Could They Affect γδ T Cells Functions?
2021
The metabolic changes that occur in tumor microenvironment (TME) can influence not only the biological activity of tumor cells, which become more aggressive and auto sustained, but also the immune response against tumor cells, either producing ineffective responses or polarizing the response toward protumor activity. γδ T cells are a subset of T cells characterized by a plasticity that confers them the ability to differentiate towards different cell subsets according to the microenvironment conditions. On this basis, we here review the more recent studies focused on altered tumor metabolism and γδ T cells, considering their already known antitumor role and the possibility of manipulating th…
Farming intensity indirectly reduces crop yield through negative effects on agrobiodiversity and key ecological functions
2022
International audience; Farming intensity and landscape heterogeneity influence agrobiodiversity and associated ecological functions. The relative contributions of these agroecosystem components to agricultural production remain unclear because of inter-relations and weather-dependant variations. Using a structural equation modelling approach, we estimated direct and indirect contributions of farming intensity (soil management, pesticide use and fertilisation) and landscape heterogeneity (of semi-natural covers and crop mosaic) to cereal crop production, in 54 fields (mostly wheat), in two years (24 and 30 fields). Indirect effects were evaluated through agrobiodiversity (carabid and plant …
Safety Evaluation of Turbo-Roundabouts with and without Internal Traffic Separations Considering Autonomous Vehicles Operation
2021
The paper presents a microsimulation approach for assessing the safety performance of turbo-roundabouts where Cooperative Autonomous Vehicles “CAVs” have been introduced into the traffic mix alongside conventional vehicles “CVs”. Based on the analysis of vehicle trajectories from VISSIM and subsequent analysis of traffic conflicts through the Surrogate Safety Assessment Model (SSAM), the research aims to evaluate the safety benefits of turbo-roundabouts where the lanes are physically separated by raised curbs, compared to roundabouts without such curbs. The paper will then describe the methodological path followed to build VISSIM models of turbo-roundabouts with and without raised curbs in …
Work Stressors and Intention to Leave the Current Workplace and Profession: The Mediating Role of Negative Affect at Work.
2022
The first aim of this study was to determine whether organisational constraints, interpersonal conflicts at work, workload and negative affect at work have a positive relationship with intention to leave a current job or profession. The second aim was to investigate whether negative affect at work mediates the relationship between work stressors and intention to leave a current job or profession. The study was a quantitative cross-sectional design in nature. Data were collected between March and April 2022. The sample consisted of 306 midwives working in the Polish public health service. The theoretical model was tested using structural equation modelling. The results confirmed positive dir…
Global Communication with Icons in Environmental Contexts
2016
Icons are small signs with fixed meanings. Icons are usually context specific. For example in the context of a hotel, the client can often find icons in hotel room books and safety guides. Scandic Hotel chain, for example, currently provides the manual for its safety system in 14 languages. There are at least two major shortcomings of this system: (1) in emergency or panic situations, it is very difficult to find your own language from the leaflet, and (2) there are no Asian languages. There is an obvious need for a global icon-based hotel safety language. In our paper, we introduce an icon-based model, language and mobile application for hotel safety. peerReviewed
Miten tuulivoimaloiden rakentaminen vaikuttaa paikallisten tuulivoima-asenteisiin? : esimerkkinä Luhangan Latamäki
2015
Energiantuotantoa fossiilisilla polttoaineilla pyritään korvaamaan uusiutuvalla energialla ilmastonmuutoksen hillitsemiseksi. EU:n ja valtion tasolla asetettuihin päästövähennys-tavoitteisiin päästäkseen Suomi pyrkii muiden keinojen ohella lisäämään tuulivoimalla tuotetun sähkön määrää tuntuvasti. Tuulivoimatuotannon negatiiviset ympäristövaikutukset ovat paikallisia, minkä vuoksi paikallistason suhtautuminen tuulivoimaa ja tuulivoima-puistoja kohtaan on merkittävässä roolissa tuulivoimapuistohankkeiden etenemisen vauhdittamisessa tai hidastamisessa. Luhangan Latamäkeen rakennettiin Keski-Suomen ensimmäinen kuuden 3 MW turbiinin tuulivoimapuisto vuonna 2014. Paikallisten suhtautumista tuuli…
Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook
2019
This is the pre-peer reviewed version of the following article: Board structures, liberal countries, and developed market economies. Do they matter in environmental reporting? An international outlook, which has been published in final form at: https://doi.org/10.1002/bse.2275. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived Versions. Previous empirical evidence has shown the effect of most corporate governance mechanisms on corporate social responsibility and environmental disclosure. However, there is scant empirical evidence that examines the influence of liberal countries, developed market economies, and board s…
Musculoskeletal disorders and disability among forest industry workers in lower and higher sickness absence groups: a case-control study
2019
Background: Musculoskeletal wellbeing and disorders and explanatory factors were investigated among forest industry employees. Methods: A new positive approach to maintenance of working ability focuses on being present at work. 140 individuals with low sickness absence (≤1.5% in hours during the past 6.5 years) and 140 controls with higher sickness absence (>1.5%), randomly selected from the source population (n = 636) in workplace clusters (n = 5), were studied. Questionnaire data on functioning, musculoskeletal disorders (MSD) and disability, work ability and wellbeing were collected (response rate 65%) during December 2012–January 2013. 183 employees (mean age 48.5; females 32%) particip…
