Colour reverse learning and animal personalities: the advantage of behavioural diversity assessed with agent-based simulations

2012

Foraging bees use colour cues to help identify rewarding from unrewarding flowers, but as conditions change, bees may require behavioural flexibility to reverse their learnt preferences. Perceptually similar colours are learnt slowly by honeybees and thus potentially pose a difficult task to reverse-learn. Free-flying honeybees (N = 32) were trained to learn a fine colour discrimination task that could be resolved at ca. 70% accuracy following extended differential conditioning, and were then tested for their ability to reverse-learn this visual problem multiple times. Subsequent analyses identified three different strategies: ‘Deliberative-decisive’ bees that could, after sev…

The manner in which populations of inhibitory (INH) and excitatory (EXC) neocortical neurons collectively encode stimulus-related information is a fundamental, yet still unresolved question. Here we address this question by simultaneously recording with large-scale multi-electrode arrays (of up to 128 channels) the activity of cell ensembles (of up to 74 neurons) distributed along all layers of 3–4 neighboring cortical columns in the anesthetized adult rat somatosensory barrel cortex in vivo. Using two different whisker stimulus modalities (location and frequency) we show that individual INH neurons – classified as such according to their distinct extracellular spike waveforms – discriminat…

Accurate Wound and Lice Detection in Atlantic Salmon Fish Using a Convolutional Neural Network

2022

The population living in the coastal region relies heavily on fish as a food source due to their vast availability and low cost. This need has given rise to fish farming. Fish farmers and the fishing industry face serious challenges such as lice in the aquaculture ecosystem, wounds due to injuries, early fish maturity, etc. causing millions of fish deaths in the fish aquaculture ecosystem. Several measures, such as cleaner fish and anti-parasite drugs, are utilized to reduce sea lice, but getting rid of them entirely is challenging. This study proposed an image-based machine-learning technique to detect wounds and the presence of lice in the live salmon fish farm ecosystem. A new equally di…

Participation in job-related lifelong learning among well-educated employees in the Nordic countries

2016

The purpose of this study was to explore participation in job-related lifelong learning (LLL) among well-educated mature workers and compare it across four Nordic countries. Although this group generally is very active in LLL, the centrality of knowledge work in society, rapid pace of skills-renewal and rising learning demands for all qualifications levels, necessitates a better understanding of the patterns and factors affecting their skill development. The paper builds on theories of learning motivation, human capital and workplace learning. Data from the Survey of Adult Skills (PIAAC) by the OECD were used. In addition to high participation rates, systematic level differences in particip…

Civil society organizations and social innovation. How and to what extent are they influencing social and political change?

2017

This study aims to understand how civil society organizations (CSOs) perform and influence public arenas. The focus of this paper is the transformative scope of social innovation initiatives promoted by CSOsin two public arenas in Brazil: the fight against electoral corruption and the protection of children and adolescents’ rights. The research consisted of three stages: 1) controversy mapping to understand the configuration ofthese public arenas and compare the trajectories of the public problems studied; 2) observation of the “field of experience” of some CSOs that perform in these arenas; and 3) analysis of “political grammars” produced in public arenas, connecting them to the performanc…

Rank response functions in an online learning environment

2021

Abstract We estimate rank response functions after receiving rank-order feedback in an online learning platform. We find that the shapes of the rank response functions depend on the outcome measure under consideration. For our effort measure, i.e., whether learners continue to interact with the platform, we can reject a linear rank response function and find significant evidence of a U-shaped relationship. For our performance measure, i.e., correctly solved exercises, we find no clear pattern overall but suggestive evidence for a linearly decreasing rank response function for individuals in the lower half of the ability distribution, i.e., the lower the rank the lower the performance.

Is the European Commission a ‘Hothouse’ for Supranationalism? Exploring Actor-Level Supranationalism

2007

The article explores actor-level supranationalism among seconded national experts (SNEs) in the European Commission. The transformative clout of the European Commission is assessed by the extent to which SNEs adopt a supranational role perception. The survey and interview data presented demonstrates that SNEs evoke multiple roles, notably departmental, epistemic and supranational roles. OLS regression analyses reveal that actor-level supranationalism among SNEs reflect (i) processes of re-socialization inside the Commission, (ii) the organizational composition of the Commission and (iii) organizational incompatibilities between the Commission and domestic government institutions.

Transformative, interdisciplinary and intercultural learning for developing HEI students’ sustainability-oriented competences : a case study

2022

AbstractThe literature has produced relevant theoretical insights into pedagogical frameworks, tools and competences that would be best suited to teach sustainability at higher education (HE). This article contributes to such a discussion using a course on sustainability developed by us as a case study. Two research questions are tackled in this article: (1) How to empower students to address urban sustainability challenges through the inclusion of transformative, interdisciplinary and intercultural learning into the current HE system? (2) Which pedagogical tools can be used to develop students’ sustainability-oriented competences? To address the research questions, the case study consists …

Les TIC en la formació universitària de mestres. El telèfon mòbil en Didàctica de l'Expressió Plàstica a la Facultat de Magisteri de la Universitat d…

2017

La present investigació pretén promoure l’ús de les TIC en l’àrea de Didàctica de l’Expressió Plàstica de la Facultat de Magisteri per contribuir a un coherent desenvolupament de l’Educació Artística amb la realitat social i cultural del segle XXI, des de la dimensió tecnològica. L’estudi respon a la necessitat d’analitzar de manera rigorosa, des de la Didàctica de les Arts Visuals, la percepció que de l’ús pedagògic de les tecnologies de la informació i la comunicació tenen determinats grups d’estudiants universitaris de Magisteri. En concret estudiarem i avaluarem la resposta que donen a l’ús educatiu del telèfon mòbil com a plataforma multimèdia en xarxa, en el tractament de continguts r…
