The Lotus japonicus ROP3 Is Involved in the Establishment of the Nitrogen-Fixing Symbiosis but Not of the Arbuscular Mycorrhizal Symbiosis

2021

Legumes form root mutualistic symbioses with some soil microbes promoting their growth, rhizobia, and arbuscular mycorrhizal fungi (AMF). A conserved set of plant proteins rules the transduction of symbiotic signals from rhizobia and AMF in a so-called common symbiotic signaling pathway (CSSP). Despite considerable efforts and advances over the past 20 years, there are still key elements to be discovered about the establishment of these root symbioses. Rhizobia and AMF root colonization are possible after a deep cell reorganization. In the interaction between the model legume Lotus japonicus and Mesorhizobium loti, this reorganization has been shown to be dependent on a SCAR/Wave-like signa…

Adsorption and Activation of Water on Cuboctahedral Rhodium and Platinum Nanoparticles

2017

Rh and Pt are widely used as the components in heterogeneous catalysts for multiple industrial applications. Because the metals are typically in the form of nanoparticles in real catalysts, it is important to carefully select models for the computational prediction of the catalytic properties. Here we report a first-principles study on the water activation, an important step in numerous catalytic reactions, using the finite-size Rh and Pt nanoparticle models and compare them to the extended surface models. We show that regardless of the model, adsorption and activation of water is practically identical for both metals, whereas the dissociation is energetically more favorable on Rh. The expe…

Kun perusopetuksen oppilaat oireilevat psyykkisesti : opettajien kokemuksia

2017

The aim of this study was to examine and interpret teachers’ experiences of pupils with emotional and behavioural disordres in comprehensive schools in Finland. The term ‘pupils with emotional and behavioural disorders’ refers here to children who either cannot or do not want to act according to the general expectations in a school climate. Children live in several social settings that affect their development, of which the most important ones are home and the school. It is known that positive teacher-pupil interaction has an advantageous effect on student adaptation, performance and behavior. However, behavior-related problematics affect the forming of interactive relationships. Educationa…

Representing the Practice of Teachers' Pedagogical Knowing

2022

This study consists of five international articles and an introductory background review. Its focus is on the nature and structure of teachers' pedagogical knowing. Pedagogical knowing is characterized as an active process by which teachers perform their duties in situations involving intense social interactions. This study treats teachers' pedagogical knowing as a broad theoretical concept and as an extended practice. Patterns of teachers' narratives are analysed as reflecting the general nature of this type of knowing. The theoretical background consists of three concepts. The idea of phronesis argues that teaching can be understood as an embodied judgement linking knowledge and virtue. T…

Vegetation dynamics on abandoned terraces of Sicily: the course and driving forces of succession

2007

In Mediterranean Europe, terrace landscapes can be found where 1) the orography is characterized by hills or mountains, 2) there is a high amount of stone outcrops and 3) the human need for agricultural production was quite high till the recent past. During the last century, many of these landscapes have been abandoned, due to their unsuitability for mechanized, intensive agriculture and due to the general land abandonment trend which arised in large parts of Europe. Since with land abandonment start secondary succession processes, the plant and animal communities linked to agroecosystems are replaced by other species which find their habitat in the developing succession stages. This proces…

Adolescent Health Literacy and Neighbourhood Features: HBSC Findings from Czech Republic, Poland, and Slovakia

2021

The role of supportive environments on health, wellbeing, and longevity has been widely recognized. However, there is no strong empirical evidence on the association between health literacy (HL) as a particular health-related competence and neighbourhoods. Therefore, the aim of the study was to assess the association between the features of neighbourhoods and the level of HL competencies of young people from three countries (Czech Republic, Poland, Slovakia). Self-reported data from an international sample of 11,521 students aged 13–15 years participating in the Health Behaviour in School-aged Children Study (HBSC) in the year 2018 were included in the analyses. The level of HL shows a stro…
