Cyclists' Perception of Maintenance and Operation of Cycling Infrastructure—Results From a Norwegian Survey
2021
Aasvik O and Bjørnskau T (2021) Cyclists’ Perception of Maintenance and Operation of Cycling Infrastructure—Results From a Norwegian Survey. Front. Psychol. 12:696317. doi: 10.3389/fpsyg.2021.696317 The Norwegian authorities want to limit the extent of car use in city areas to existing levels. Such a limitation would help combat climate change, improve health of citizens, and alleviate congestion. This implies that any further increase in transport needs will have to be met by walking, cycling and use of public transport. Reaching this ambitious goal requires knowledge about cyclists' preferences concerning operation and maintenance (M&O) of roads and foot/cycle paths. Previous research sug…
Pedagogical Perspectives in Higher Education Research
2017
Higher education pedagogy is a fairly young research field, stemming from early research during the 1970s and growing widely since the 1990s. The following sections present firstly main research lines focusing on student learning and secondly those examining teaching and teachers. peerReviewed
Pair interactions in online assessments of collaborative problem solving: case-based portraits
2018
This exploratory case study focuses on how pairs of students can build a shared understanding and acquire collaborative problem-solving (CPS) practices during an online assessment of CPS skills, which is seen in the context of the CPS construct, in a symmetrical and asymmetrical task type. Even though CPS is widely recognised as a core twenty-first-century competency, its nature is not yet well understood. Also, until recently, most of studies have focused on the individual’s solution to a problem or on the skills individuals bring into a problem-solving space. This study extends from an individual- to group-level focus in CPS, emphasising the role and quality of the social aspects in CPS p…
Longitudinal Effects of the Home Learning Environment and Parental Difficulties on Reading and Math Development Across Grades 1–9
2020
This study focuses on parental reading and mathematical difficulties, the home literacy environment, and the home numeracy environment as well as their predictive role in Finnish children’s reading and mathematical development through Grades 1–9. We examined if parental reading and mathematical difficulties directly predict children’s academic performance and/or if they are mediated by the home learning environment. Mothers (n = 1590) and fathers (n = 1507) reported on their reading and mathematical difficulties as well as on the home environment (shared reading, teaching literacy, and numeracy) when their children were in kindergarten. Tests for reading fluency, reading comprehension, and …
Structural and optical characterization of ZnS ultrathin films prepared by low-temperature ALD from diethylzinc and 1.5-pentanedithiol after various …
2019
The structural and optical evolution of the ZnS thin films prepared by atomic layer deposition (ALD) from the diethylzinc (DEZ) and 1,5-pentanedithiol (PDT) as zinc and sulfur precursors was studied. A deposited ZnS layer (of about 60 nm) is amorphous, with a significant S excess. After annealing, the stoichiometry improved for annealing temperatures &ge
Synthesis, Optical, and Morphological Studies of ZnO Powders and Thin Films Fabricated by Wet Chemical Methods
2020
Zinc oxide nanoparticles were prepared from Zn5(CO3)2(OH)6 precursor, capped with poly(vinylpyrrolidone) (PVP), and annealed at 600 °
Mejora de la calidad de vida del residente a través de estrategias de marketing: Un análisis comparado entre México y España.
2015
Los gobiernos locales hoy en día deben desarrollarse y crecer igual que las grandes empresas existentes en el mundo. Para ello, deben gestionar y administrar sus territorios geográficos como si de una marca se tratara. En este tenor, la actitud hacia la marca-ciudad favorece la creación de actitudes positivas hacia la sostenibilidad. En este marco, la presente tesis persigue los cinco objetivos siguientes: (i) Abordar el papel del marketing experiencial basado en mega-eventos para construir, tanto actitud hacia la marca-ciudad como hacia la sostenibilidad. (ii) Abordar el papel del marketing verde (orientación ecológica) para construir, tanto actitud hacia la marca-ciudad como hacia la sost…
Influence of aryl hydrocarbon- (Ah) receptor and genotoxins on DNA repair gene expression and cell survival of mouse hepatoma cells
2009
The aryl hydrocarbon receptor (AhR) mediates toxicity of a variety of environmental pollutants such as polycyclic aromatic hydrocarbons (PAHs) and dioxins. However, the underlying mechanisms and genetic programmes regulated by AhR to cause adverse effects but also to counteract poisoning are still poorly understood. Here we analysed the effects of two AhR ligands, benzo[a]pyrene (B[a]P), a DNA damaging tumour initiator and promotor and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a pure tumour promoter, on cell survival and on nucleotide excision repair (NER) gene expression. NER deals with so called "bulky" DNA adducts including those generated by enzymatically activated B[a]P. Therefore, t…
Papel neuroprotector de las células mesenquimales humanas a nivel ocular en la esclerosis múltiple
2015
Entre las enfermedades neurodegenerativas del sistema nervioso central, la esclerosis múltiple (EM) es una enfermedad inflamatoria crónica considerada causa principal de discapacidad neurológica no traumática en el adulto joven. Los tratamientos actuales se basan en el uso de inmunosupresores para control de la inflamación en fases precoces. Estos tratamientos han demostrado la reducción en las tasas de recurrencia y actividad de la enfermedad, pero han tenido un impacto modesto en la progresión de la misma y la discapacidad asociada, sobre todo en formas agresivas. Modelos animales de EM han permitido recientemente estudiar el efecto de las hMSCs (células mesenquimales humanas) tras infusi…
New Insights Into Causal Pathways Between the Pediatric Age-Related Physical Activity Decline and Loss of Control Eating: A Narrative Review and Prop…
2020
Research consistently suggests that loss of control (LOC) eating in children and adolescents is a key factor contributing to pediatric obesity and eating disorders. However, causes of pediatric LOC eating are yet unclear, and there is a lack of longitudinal research investigating the developmental processes contributing to LOC eating and related outcomes in youth. Physical activity is an understudied behavior that declines during middle childhood to adolescence and may exert an influence in the development of LOC eating via its impact on executive functioning. While physical activity levels and executive functioning have been linked to regulation of eating, no research has examined the mech…
