    When using online nudges to steer people in the right direction while they are making a decision, there is usually one preferable outcome. What might happen if the user experience is inadequate, will the nudges still work or might they be undermined? In this paper we investigate the correlation between user experience and digital nudges in a decision making process. A user A/B test was conducted to investigate the problem. The test participants visited one of two websites that included the same nudges where they were nudged to choose option (a) instead of (b). The only difference in the websites was the quality of the user experience, one website design had a good user experience while the other one offered an inadequate user experience. The results showed that everyone who was assigned the good user experience chose (a), while two of the inadequate experience participants chose (b). The results indicate that user experience design can be used for digital nudging

    This paper reports on a research study about principals’ strategic leadership and organisation of schools within established tablet-based one-to-one computing initiatives. The aim was to investigate how principals lead and guide one-to-one computing initiatives in K–12 education. The research questions focused on principals’ expressed intentions and their strategic leadership and organisation when implementing tablet-based one-to-one computing initiatives in Swedish schools. The empirical material was collected through semi-structured interviews with seven principals in five municipalities where the schools had used tablets for more than six months within a one-to-one computing initiative. The findings are organised by themes concerning one-to-one computing as a strategy to change teaching and working methods, using technology for adapting teaching and learning to every pupil’s needs, and strategies for organisation. The findings show that marketisation of schools (e.g. the school-choice reform) in combination with the annual presentation of national rankings have had an impact on the financial situations of schools because they receive a voucher for every attending pupil. The participating principals’ strategic leadership concerning their intentions and applied strategies on how to lead and organise the digitalised school are an attempt to meet the demands that the marketisation and digitalisation of Swedish schools requires

    Power and control in the one-to-one computing classroom: students’ perspectives on teachers’ didactical design

    This paper reports on a research study that scrutinised the student perspective on teachers’ different didactical designs from lessons in the one-to-one computing classroom. Specifically, the aim was to describe and understand three different clusters of didactical design in the one-to-one computing classroom from the student perspective. Each of the three clusters represents different interactions between teachers and students. The research questions embrace how the teachers or students, through the didactical design, will have an advantage over the other. The empirical material was based on student focus groups interviews, enhanced through the method of stimulated recall where different photographs of teaching and learning situations from the one-to-one computing classroom were shown to the students. The results demonstrate three empirical themes: students’ learning in class, students’ learning outside class, and classroom assessment. From a theoretical lens of power and control, the students’ reasoning demonstrates approaches to how teachers regulate students and to how students can make decisions in their learning process. For handling students’ demands, specifically in pedagogical plans, the one-to-one computing classroom becomes one component for making students’ learning processes smoother regarding when to study and how to study

    Dental caries is a chronic infectious disease that affects billions of people with large individual differences in activity. We investigated whether PRH1 and PRH2 polymorphisms in saliva acidic proline-rich protein (PRP) receptors for indigenous bacteria match and predict individual differences in the development of caries. PRH1 and PRH2 variation and adhesion of indigenous and cariogenic (Streptococcus mutans) model bacteria were measured in 452 12-year-old Swedish children along with traditional risk factors and related to caries at baseline and after 5-years. The children grouped into low-to-moderate and high susceptibility phenotypes for caries based on allelic PRH1, PRH2 variation. The low-to-moderate susceptibility children (P1 and P4a-) experienced caries from eating sugar or bad oral hygiene or infection by S. mutans. The high susceptibility P4a (Db, PIF, PRP12) children had more caries despite receiving extra prevention and irrespective of eating sugar or bad oral hygiene or S. mutans-infection. They instead developed 3.9-fold more caries than P1 children from plaque accumulation in general when treated with orthodontic multibrackets; and had basic PRP polymorphisms and low DMBT1-mediated S. mutans adhesion as additional susceptibility traits. The present findings thus suggest genetic autoimmune-like (P4a) and traditional life style (P1) caries, providing a rationale for individualized oral care

    Adaptive Lévy Walks in Foraging Fallow Deer

    Get PDF
    Background: Lévy flights are random walks, the step lengths of which come from probability distributions with heavy power-law tails, such that clusters of short steps are connected by rare long steps. Lévy walks maximise search efficiency of mobile foragers. Recently, several studies raised some concerns about the reliability of the statistical analysis used in previous analyses. Further, it is unclear whether Lévy walks represent adaptive strategies or emergent properties determined by the interaction between foragers and resource distribution. Thus two fundamental questions still need to be addressed: the presence of Lévy walks in the wild and whether or not they represent a form of adaptive behaviour. Methodology/Principal Findings: We studied 235 paths of solitary and clustered (i.e. foraging in group) fallow deer (Dama dama), exploiting the same pasture. We used maximum likelihood estimation for discriminating between a power-tailed distribution and the exponential alternative and rank/frequency plots to discriminate between Lévy walks and composite Brownian walks. We showed that solitary deer perform Lévy searches, while clustered animals did not adopt that strategy. Conclusion/Significance: Our demonstration of the presence of Lévy walks is, at our knowledge, the first available which adopts up-to-date statistical methodologies in a terrestrial mammal. Comparing solitary and clustered deer, we concluded that the Lévy walks of solitary deer represent an adaptation maximising encounter rates with forage resources and not a

    GNB: Projet de recherche finalisée à l’interface recherche-gestion et ses interactions avec BGF

    La gestion durable des forêts repose largement sur la biodiversité dont le fonctionnement reste cependant encore très insuffisamment connu. Il en découle la nécessité d’améliorer, de manière générale, le socle de connaissances relatif à la biodiversité et, plus particulièrement, d’analyser les interactions entre changement climatique, productivité forestière et biodiversité en forêt. Par ailleurs, les stratégies et décisions des acteurs influent sur ces interactions et constituent également des objets d’étude à privilégier. C’est pourquoi le programme de recherche « Biodiversité, gestion forestière et politiques publiques » a lancé en 2013 un appel à projets de recherche avec deux entrées : - l’une par les sciences de la nature axée sur le changement climatique, les mesures de gestion et la dynamique de la biodiversité dans les écosystèmes ; - l’autre par les sciences humaines et sociales sur les stratégies et décisions des acteurs, la gouvernance et les politiques publiques correspondant à la première entrée. Le présent colloque a pour objectifs de : - présenter les résultats des cinq projets de recherche qui ont été sélectionnés à cette occasion sur chacune des deux entrées en les accompagnant en tant que de besoin de regards complémentaires et en illustrant l’un des projets par une visite sur le terrain ; - initier une réflexion sur le progrès des connaissances dans ce domaine, en s’inspirant du devenir de projets antérieurs et en identifiant les principales lacunes à combler. Il se déroulera en trois sessions, chacune introduite par des exposés d’une quinzaine de minutes et conclue par une table ronde permettant un débat avec les participants et les invités

    Words apart: Standardizing forestry terms and definitions across European biodiversity studies

    Get PDF
    Forest biodiversity studies conducted across Europe use a multitude of forestry terms, often inconsistently. This hinders the comparability across studies and makes the assessment of the impacts of forest management on biodiversity highly context-dependent. Recent attempts to standardize forestry and stand description terminology mostly used a top-down approach that did not account for the perspectives and approaches of forest biodiversity experts. This work aims to establish common standards for silvicultural and vegetation definitions, creating a shared conceptual framework for a consistent study on the effects of forest management on biodiversity. We have identified both strengths and weaknesses of the silvicultural and vegetation information provided in forest biodiversity studies. While quantitative data on forest biomass and dominant tree species are frequently included, information on silvicultural activities and vegetation composition is often lacking, shallow, or based on broad and heterogeneous classifications. We discuss the existing classifications and their use in European forest biodiversity studies through a novel bottom-up and top-driven review process, and ultimately propose a common framework. This will enhance the comparability of forest biodiversity studies in Europe, and puts the basis for effective implementation and monitoring of sustainable forest management policies. The standards here proposed are potentially adaptable and applicable to other geographical areas and could be extended to other forest interventions.

    Where are we now with European forest multi-taxon biodiversity and where can we head to?

    The European biodiversity and forest strategies rely on forest sustainable management (SFM) to conserve forest biodiversity. However, current sustainability assessments hardly account for direct biodiversity indicators. We focused on forest multi-taxon biodiversity to: i) gather and map the existing information; ii) identify knowledge and research gaps; iii) discuss its research potential. We established a research network to fit data on species, standing trees, lying deadwood and sampling unit description from 34 local datasets across 3591 sampling units. A total of 8724 species were represented, with the share of common and rare species varying across taxonomic classes: some included many species with several rare ones (e.g., Insecta); others (e.g., Bryopsida) were represented by few common species. Tree-related structural attributes were sampled in a subset of sampling units (2889; 2356; 2309 and 1388 respectively for diameter, height, deadwood and microhabitats). Overall, multitaxon studies are biased towards mature forests and may underrepresent the species related to other developmental phases. European forest compositional categories were all represented, but beech forests were overrepresented as compared to thermophilous and boreal forests. Most sampling units (94%) were referred to a habitat type of conservation concern. Existing information may support European conservation and SFM strategies in: (i) methodological harmonization and coordinated monitoring; (ii) definition and testing of SFM indicators and thresholds; (iii) data-driven assessment of the effects of environmental and management drivers on multi-taxon forest biological and functional diversity, (iv) multi-scale forest monitoring integrating in-situ and remotely sensed information.
