The down-regulation of disgust by implementation intentions: experiential and physiological concomitants

Emotion regulation plays a key role in mental health and psychopathology. Therefore, it seems important to develop effective forms of emotion regulation. Implementation intentions are if-then plans that help people attain their self-regulatory goals. Perspective-taking and response-focused implementation intentions have been shown to reduce feelings of unpleasantness and arousal, respectively, in response to briefly presented disgusting pictures. The present study addressed the open research questions whether forming these types of implementation intentions is effective in regulating affect during prolonged presentation of disgusting pictures, and whether it is associated with changes in physiological arousal. Eighty-one participants viewed disgusting, neutral, and pleasant pictures of 6 s duration under four instructions: the goal intention to not get disgusted, this goal intention furnished with a perspective-taking or a response-focused implementation intention, and no emotion regulation instructions. The dependent variables were ratings of disgust, valence, arousal, and electrodermal activity. Only perspective-taking implementation intention participants significantly reduced their disgust and unpleasantness as compared to goal-intention and control participants. Arousal and skin conductance did not significantly differ between conditions. The effectiveness of response-focused but not perspective-taking implementation intentions seems to be substantially reduced during sustained exposure duration.

Regulation of bistable ICEclc transfer in pseudomonas knackmussii B13

L'élément génétique intégratif et conjugatif auto-transférable de 103 kb qui se trouve dans le génome de Pseudomonas knackmussii B13 (ICEc/c) confère la capacité de dégrader le 3-chlorobenzoate et le 2-aminophénol. L'élément ICE c/c peut être transféré par conjugaison de la souche B13 à diverses bêta- et gamma- protéobactéries. Seule une sous-population de 3 à 5% des cellules transfère l'élément, les cellules dites "compétentes pour le transfert". L'acquisition de la compétence pour le transfert est vraisemblablement la conséquence d'une régulation bistable, conduisant une partie des cellules au transfert de l'élément ICE c/c tandis que, dans les autres, l'élément reste quiescent et ne se transfère pas. À ce jour, les mécanismes et les acteurs moléculaires qui régulent l'activation bistable de l'élément sont restés inconnus. Mon travail de doctorat visait à identifier les éléments bistables du régulon de la compétence pour le transfert et d'analyser les fondements moléculaires de la bistabilité de l'élément ICE c/c chez P. knackmussii. Le premier chapitre introduit le thème du transfert génétique horizontal avec un accent particulier sur les éléments intégratifs et conjugatifs (ICE) et ICEcIc. L'état actuel des connaissances sur l'organisation génétique, la régulation, l'intégration et le transfert de différents modèles de ICEs est exposé en détail. En outre, je m'étends sur les phénomènes d'hétérogénéité et de bistabilité phénotyplques, qu'on peut distinguer dans une population isogénique dans des conditions de culture homogènes, et qui sont susceptibles de jouer un rôle dans le transfert de l'élément ICE c/c, dans la mesure où il ne s'active et n'est transférable que dans une très petite sous-population de cellules. Dans le chapitre 2, je présente une analyse globale des régions promotrices minimales des gènes appartenant au régulon de la compétence pour le transfert de l'élément ICE c/c. Nous avons étudié les caractéristiques d'expression des promoteurs et, s'ils s'avéraient bistables, leur activation dans le temps par comparaison avec le mutant lntB13. Pour ce faire, nous avons utilisé des fusions de promoteurs avec des gènes rapporteurs et testé l'expression bistable chez P. knackmussii par microscopie à épifluorescence. Pour six promoteurs présentant une expression bistable, nous avons employé de la microscopie temporelle pour déterminer la chronologie de leur expression par rapport à Pint et PinR. Parmi eux, nous avons identifié deux gènes exprimés précocement et trois gènes exprimés tardivement dans le processus d'acquisition de la compétence de transfert. Dans le chapitre 3, j'expose une analyse d'expression génétique pour l'un des groupes de gènes dont la transcription est la plus élevée dans la région conservée de ICE c/c, les gènes orf81655-orf68241 contenus dans une région de 14 kb. Nous montrons d'abord que cet opéron fait partie du même régulon bistable que intB13 et inrR et analysons les caractéristiques génétiques qui conduisent à une transcription élevée. Nous étudions les fonctions biologiques de ce groupe de gènes par des délétlons ciblées et montrons que certaines d'entre elles empêchent le transfert de l'élément. Nous approfondissons la caractérlsatlon de I'orf8l655 en construisant une fusion transcrlptionnelle avec le gène codant pour la protéine fluorescente verte (egfp) (en utilisant le système minl-Tn5). L'expression de Vorf81655 dans des cellules individuelles est comparée au signal mesuré par hybridation in situ en fluorescence (FISH) sur le ARN messager du gène. En utilisant FISH, des délétlons du promoteur et de l'analyse directe de transcription, nous avons localisé la région promotrice du groupe de gènes. En outre, nous avons utilisé des mutations dirigées pour comprendre la bistabilité de cette région promotrice, caractérisée par une transcription très élevée et une traduction lente de l'ARN messager.  Dans le chapitre 4, nous nous efforçons de comprendre comment la bistabilité est générée au sein du régulon te de l'élément ICE c/c. Pour ce faire, nous avons tenté de reconstituer une expression bistable, dans un hôte qui ne présente pas de bistabilité naturellement, à partir d'éléments génétiques individuels. L'hôte choisi est Pseudomonas putida dans lequel nous avons introduit une copie unique de Pint, PinR ou PaipA fusionnés à la egfp, construits qui permettent d'observer l'apparition de bistabilité. Nous avons ensuite construit différents assemblages de composants génétiques de l'élément ICE c/c, en nous concentrant sur la région parA-inrR. En effet, nous avons pu démontrer qu'une expression bistable apparaît dans P. putida grâce à ces éléments en l'absence de l'élément ICE c/c complet. À noter que la plupart des construits génétiques activent PaipA ou P|,,R, mais qu'un seul recrée la bistabilité de Pint, ce qui suggère que la région parA-inrR permet à la fois d'engendrer la bistabilité et d'opérer la transition entre les promoteurs précoces et les promoteurs tardifs du régulon de la bistabilité. Dans le chapitre 5, nous concluons sur une discussion de la pertinence de nos résultats et sur de futures perspectives de recherche. -- The 103-kb self-transmissible integrative and conjugative element (ICE) of Pseudomonas knackmussii B13 (ICEc/c) confers the capacity to degrade 3- chlorobenzoate and 2-aminophenol. ICEc/c can be conjugated from strain B13 to a variety of Beta- and Gammaproteobacteria. Interestingly, ICE c/c transfer is observed in a subpopulatlon of cells (3-5%) only, the so-called 'transfer competent' cells. The formation of transfer competence (tc) is thought to be the consequence of a 'bistable' decision, which forces those cells to follow the developmental path which leads to ICEc/c transfer, whereas in others ICE c/c remains silent and does not transfer. So far, the mechanisms and molecular partners generating this bistable transfer activation in cells of P. knackmussii B13 remain mostly unidentified. This thesis aimed at understanding the extent of the tc bistability regulon and to dissect the molecular basis of bistabillty formation of ICEc/c in P. knackmussii. The first chapter is a general Introduction on horizontal gene transfer (HGT) with particular emphasis on ICEs and ICE c/c. The emphasis is made on the current knowledge about the HGT gene organization, regulation and specific integration and transfer aspects of the different ICEs models. Furthermore, I focus on the phenomena of phenotypic heterogeneity and bistability (the property of two distinguishable phenotypes existing within an isogenic population under homogeneous conditions), which may play a particular role in ICEc/c behaviour, since ICE activation and transfer only occurs in a very small subpopulation of cells. In Chapter Two, I focus on a global analysis of the different core promoters that might belong to the ICEc/c tc pathway regulon. We studied both expression patterns of ICEc/c promoters and, once being identified as "bistable", their temporal activation compared to that of intB13. In order to do this, we used promoter reporter fusions and tested blstability expression in P. knackmussii using epifluorescence microscopy. For the 6 promoters that showed bistable expression, we used time-lapse microscopy to study the timing of promoter expression in comparison to that of P,,,t or PlnR. We could establish two "early" and 3 "late" phase promoters in the process of transfer competence. In Chapter Three, I focused my attention on analysis of gene expression of one of the most highly transcribed gene clusters in the conserved core region of ICEc/c, a 14-kb gene cluster formed by the genes orf81655-orf68241. First we showed that this operon is part of the same bistability 'regulon' as intB13 and inrR, and analysed the genetic features that lead to high transcription. We studied the potential biological function of this cluster for ICE c/c by making specific gene deletions, showing that some interrupt ICEc/c transfer. We further analysed the orfdl655 promoter by constructing transcriptional egfp fusion reporter strains using the miniTn5 delivery system. Expression of the orf81655 promoter in single cells was compared to signals measured by Fluorescence In Situ Hybridization (FISH) on orfSl655 mRNA. We localized the promoter region of the gene cluster using FISH, promoter deletions, and by direct transcript analysis. We further used site-directed mutagenesis to understand the bistability character of the promoter region and the extremely high transcription but low translation from this mRNA. In Chapter Four, we set out to understand how bistability is generated in the tc pathway of ICEc/c. For this we tried rebuilding bistable expression from ICEc/c individual gene components in a host, which normally does not display bistability. As host we used P. putida without ICEc/c but with a single copy Pint-, PlnR- or PalpA- egfp fusion that enabled us to verify bistability formation. Subsequently, we built different assemblages of ICEc/c gene components, focusing on the parA-inrR region. Indeed, we found that bistable expression can be build from those components in P. putida without ICEc/c. Interestingly, most genetic constructs activated PaipA or PlnR, but only one resulted in bistable activation of PinT. This suggests that the parA-inrR region acts as a bistability "generator", but also as a bistability "relay" from early to late promoters in the tc pathway hierarchy. In the final fifth chapter, we conclude with a discussion of the relevance of the present thesis and the resulting perspectives for future studies.

What can ecosystems learn? Expanding evolutionary ecology with learning theory.

BACKGROUND: The structure and organisation of ecological interactions within an ecosystem is modified by the evolution and coevolution of the individual species it contains. Understanding how historical conditions have shaped this architecture is vital for understanding system responses to change at scales from the microbial upwards. However, in the absence of a group selection process, the collective behaviours and ecosystem functions exhibited by the whole community cannot be organised or adapted in a Darwinian sense. A long-standing open question thus persists: Are there alternative organising principles that enable us to understand and predict how the coevolution of the component species creates and maintains complex collective behaviours exhibited by the ecosystem as a whole? RESULTS: Here we answer this question by incorporating principles from connectionist learning, a previously unrelated discipline already using well-developed theories on how emergent behaviours arise in simple networks. Specifically, we show conditions where natural selection on ecological interactions is functionally equivalent to a simple type of connectionist learning, 'unsupervised learning', well-known in neural-network models of cognitive systems to produce many non-trivial collective behaviours. Accordingly, we find that a community can self-organise in a well-defined and non-trivial sense without selection at the community level; its organisation can be conditioned by past experience in the same sense as connectionist learning models habituate to stimuli. This conditioning drives the community to form a distributed ecological memory of multiple past states, causing the community to: a) converge to these states from any random initial composition; b) accurately restore historical compositions from small fragments; c) recover a state composition following disturbance; and d) to correctly classify ambiguous initial compositions according to their similarity to learned compositions. We examine how the formation of alternative stable states alters the community's response to changing environmental forcing, and we identify conditions under which the ecosystem exhibits hysteresis with potential for catastrophic regime shifts. CONCLUSIONS: This work highlights the potential of connectionist theory to expand our understanding of evo-eco dynamics and collective ecological behaviours. Within this framework we find that, despite not being a Darwinian unit, ecological communities can behave like connectionist learning systems, creating internal conditions that habituate to past environmental conditions and actively recalling those conditions.

Debating as a classroom tool for adapting learning outcomes to the European higher education area

The creation of the European Higher Education Area has meant a number of significant changes to the educational structures of the university community. In particular, the new system of European credits has generated the need for innovation in the design of curricula and teaching methods. In this paper, we propose debating as a classroom tool that can help fulfill these objectives by promoting an active student role in learning. To demonstrate the potential of this tool, a classroom experiment was conducted in a bachelor’s degree course in Industrial Economics -Regulation and Competition-, involving a case study in competition policy and incorporating the techniques of a conventional debate -presentation of standpoints, turns, right to reply and summing up-. The experiment yielded gains in student attainment and positive assessments of the subject. In conclusion, the incorporation of debating activities helps students to acquire the skills, be they general or specific, required to graduate successfully in Economics.

Continuing Medical Education Self-Assessment Questions Vol. 50, No. 2 - April 2014. Focal vibration in neurorehabilitation.

During the last decade, many studies have been carried out to understand the effects of focal vibratory stimuli at various levels of the central nervous system and to study pathophysiological mechanisms of neurological disorders as well as the therapeutic effects of focal vibration in neurorehabilitation. This review aimed to describe the effects of focal vibratory stimuli in neurorehabilitation including the neurological diseases or disorders like stroke, spinal cord injury, multiple sclerosis, Parkinson's' disease and dystonia. In conclusion, focal vibration stimulation is well tolerated, effective and easy to use, and it could be used to reduce spasticity, to promote motor activity and motor learning within a functional activity, even in gait training, independent from etiology of neurological pathology. Further studies are needed in the future well- designed trials with bigger sample size to determine the most effective frequency, amplitude and duration of vibration application in the neurorehabilitation.

Design and evaluation of learning algorithms for dynamic resource management in virtual networks

Network virtualisation is considerably gaining attentionas a solution to ossification of the Internet. However, thesuccess of network virtualisation will depend in part on how efficientlythe virtual networks utilise substrate network resources.In this paper, we propose a machine learning-based approachto virtual network resource management. We propose to modelthe substrate network as a decentralised system and introducea learning algorithm in each substrate node and substrate link,providing self-organization capabilities. We propose a multiagentlearning algorithm that carries out the substrate network resourcemanagement in a coordinated and decentralised way. The taskof these agents is to use evaluative feedback to learn an optimalpolicy so as to dynamically allocate network resources to virtualnodes and links. The agents ensure that while the virtual networkshave the resources they need at any given time, only the requiredresources are reserved for this purpose. Simulations show thatour dynamic approach significantly improves the virtual networkacceptance ratio and the maximum number of accepted virtualnetwork requests at any time while ensuring that virtual networkquality of service requirements such as packet drop rate andvirtual link delay are not affected.

The FaceUOC Project : An Open Social Learning experience by the Open University of Catalonia

The possibilities and expansion of the use of Web 2.0 has opened up a world of possibilities in online learning. In spite of the integration of these tools in education major changes are required in the educational design of instructional processes.This paper presents an educational experience conducted by the Open University of Catalonia using the social network Facebook for the purpose of testing a learning model that uses a participation and collaboration methodology among users based on the use of open educational resources.- The aim of the experience is to test an Open Social Learning (OSL) model, understood to be a virtual learning environment open to the Internet community, based on the use of open resources and on a methodology focused on the participation and collaboration of users in the construction of knowledge.- The topic chosen for this experience in Facebook was 2.0 Journeys: online tools and resources. The objective of this 5 weeks course was to provide students with resources for managing the various textual, photographic, audiovisual and multimedia materials resulting from a journey.- The most important changes in the design and development of a course based on OSL are the role of the teacher, the role of the student, the type of content and the methodology:- The teacher mixes with the participants, guiding them and offering the benefit of his/her experience and knowledge.- Students learn through their participation and collaboration with a mixed group of users.- The content is open and editable under different types of license that specify the level of accessibility.- The methodology of the course was based on the creation of a learning community able to self-manage its learning process. For this a facilitator was needed and also a central activity was established for people to participate and contribute in the community.- We used an ethnographic methodology and also questionnaires to students in order to acquire results regarding the quality of this type of learning experience.- Some of the data obtained raised questions to consider for future designs of educational situations based on OSL:- Difficulties in breaking the facilitator-centred structure- Change in the time required to adapt to the system and to achieve the objectives- Lack of commitment with free courses- The trend to return to traditional ways of learning- Accreditation- This experience has taught all of us that education can happen any time and in any place but not in any way.

Differential Regulation of c-FLIP Isoforms Through Post-translational Modifications

Cells are constantly responding to signals from the surrounding tissues and the environment. To dispose of infected and potentially dangerous cells, to ensure the optimal execution of developmental processes and to maintain tissue homeostasis, a multicellular organism needs to tightly control both the number and the quality of its cells. Apoptosis is a form of active cellular self-destruction that enables an organism to regulate its cell number by deleting damaged or potentially dangerous cells. Apoptosis can be induced by death ligands, which bind to death receptors on the cell surface. Ligation of the receptors leads to the formation of an intracellular death inducing signaling complex (DISC). One of the DISC components is caspase-8, a protease that triggers the caspase cascade and is thereby a key initiator of programmed cell death. The activation of caspase-8 is controlled by the cellular FLICE-inhibitory proteins (c-FLIPs). Consequently, sensitivity towards receptor-mediated apoptosis is determined by the amount of c-FLIP, and the c-FLIP levels are actively regulated for example during erythroid differentiation of K562 erythroleukemia cells and by hyperthermia in Jurkat leukemia cells. The aim of my thesis was to investigate how c-FLIP is regulated during these processes. We found that c-FLIP isoforms are short-lived proteins, although c-FLIPS had an even shorter half-life than c-FLIPL. In both experimental models, increased death receptor sensitivity correlated with induced ubiquitylation and consequent proteasomal degradation of c-FLIP. Furthermore, we elucidated how phosphorylation regulates the biological functions and the turnover of c-FLIP, thereby contributing to death receptor sensitivity. We mapped the first phosphorylation sites on c-FLIP and dissected how their phosphorylation affects c-FLIP. Moreover, we demonstrated that phosphorylation of serine 193, a phosphorylated residue common to all c-FLIPs, is primarily mediated by the classical PKC. Furthermore, we discovered a novel connection between the phosphorylation and ubiquitylation of c-FLIP: phosphorylation of S193 protects c-FLIP from ubiquitylation. Surprisingly, although all c-FLIP isoforms are phosphorylated on this conserved residue, the biological outcome is different for the long and short isoforms, since S193 specifically prolongs the half-lives of the short c-FLIP isoforms, but not c-FLIPL. To summarize, we show that c-FLIP proteins are modified by ubiquitylation and phosphorylation, and that the biological outcomes of these modifications are isoform-specifically determined.

Genetic Factors in the Regulation of Striatal and Extrastriatal Dopamine D2 Receptor Expression

Positron emission tomography (PET) studies on healthy individuals have revealed a marked interindividual variability in striatal dopamine D2 receptor density that can be partly accounted for by genetic factors. The examination of the extrastriatal lowdensity D2 receptor populations has been impeded by the lack of suitable tracers. However, the quantification of these D2 receptor populations is now feasible with recently developed PET radioligands. The objective of this thesis was to study brain neurobiological correlates of common functional genetic variants residing in candidate genes relevant for D2 receptor functioning. For this purpose, healthy subjects were studied with PET imaging using [₁₁C]raclopride and [₁₁C]FLB457 as radioligands. The candidate genes examined in this work were the human D2 receptor gene (DRD2) and the catechol-Omethyltransferase gene (COMT). The region-specific genotypic influences were explored by comparing D2 receptor binding properties in the striatum, the cortex and the thalamus. As an additional study objective, the relationship between cortical D2 receptor density and a cognitive phenotype i.e. verbal memory and learning was assessed. The main finding of this study was that DRD2 C957T genotype altered markedly D2 receptor density in the cortex and the thalamus whereas in the striatum the C957T genotype affected D2 receptor affinity, but not density. Furthermore, the A1 allele of the DRD2-related TaqIA polymorphism showed increased cortical and thalamic D2 receptor density, but had the opposite effect on striatal D2 receptor density. The DRD2 –141C Ins/Del or the COMT Val158Met genotypes did not change D2 receptor binding properties. Finally, unlike previously reported, cortical D2 receptor density did not show any significant correlation with verbal memory function. The results of this study suggest that the C957T and the TaqIA genotypes have region-specific neurobiological correlates in brain dopamine D2 receptor availability in vivo. The biological mechanisms underlying these findings are unclear, but they may be related to the region-specific regulation of dopamine neurotranssion, gene/receptor expression and epigenesis. These findings contribute to the understanding of the genetic regulation of dopamine and D2 receptor-related brain functions in vivo in man. In addition, the results provide potentially useful endophenotypes for genetic research on psychiatric and neurological disorders.

From "being to the self" to "become to be": on development of autonomy construction in nursing students

Objective: To understand nursing student's self-consciousness and his/her autonomy in the discipline of fundamentals of professional care in the context of a liberating pedagogical proposal. Methodology. This qualitative, case-based research in the model of Ludke and André involved 14 students participating in the discipline. Data were collected by non-participatory observation and analysis of documents. Field observation was conducted from March to July 2010 and data were collected according to the proposal of Minayo: pre-analysis, exploration of material and treatment of results. Results. We constructed two thematic units of analysis: from "being to the self" and exercise of "become to be". Conclusion. When nursing students feel more liberty, they have the opportunity to substitute the scary prospect of learning something new material to something that motivates their curiosity and leads them to become more autonomous.

Intercultural bridges in teenagers' theatrical events : performing self and constructing cultural identity through a creative drama process

The overriding aim of this drama educational case study is to deepen the understanding of meaning making in a creative intercultural youth theatre process and to examine it in the context of the 10th European Children's TheatreEncounter. The research task is to give a theoretical description of some key features of a creative drama process as the basis for theory about meaning makingin physical theatre. The first task is to illuminate the culture-historical connections of the multilayered practice of the EDERED-association. The second taskis to analyse and interpret theatrical meaning making. The ethnographical research site is regarded as a theatrical event. The analysis of the theatrical eventis divided into four segments: cultural contexts, contextual theatricality, theatrical playing and playing culture. These segments are connected with four research questions: What are the cultural contexts of a creative drama process? How can the organisation of the Encounter, genres, aesthetic codes and perception ofcodes be seen to influence the lived experiences of the participants? What are some of the key phases and characteristics in a creative practice? What kind of cultural learning can be interpreted from the performance texts? The interpretative question concerns identity and community (re)construction. How are the categories, `community´ and `child´ constructed in the Encounter culture? In this drama educational case study the research material (transcribed interviews, coded questionnaire answers, participant drawings, videotaped process text and performance texts) are examined in a multi-method analysis in the meta-theoretical framework of Dewey's naturalistic pragmatism. A three-dimensional research interest through a combination of lived experiences, social contexts and cultural-aesthetical practices compared with drama-educational practices required the methodological project of cultural studies. Furthermore, the critical interpretation of cultural texts is divided into three levels of analyses which are called description, structural analysis and theoretical interpretation. Dialogic validity (truthfulness, self-reflexivity and polyvocality) is combined with contextual validity (sensitivity to social context and awareness of historicity) and with deconstructive validity (awareness of the social discourses). My research suggests that itis possible, by means of physical theatre, to construct symbolic worlds where questions about intercultural identity and multilingual community are examined and where provisional answers are constructed in social interaction.

Methods for construction and analysis of computational models in systems biology : applications to the modelling of the heat shock response and the self-assembly of intermediate filaments

Systems biology is a new, emerging and rapidly developing, multidisciplinary research field that aims to study biochemical and biological systems from a holistic perspective, with the goal of providing a comprehensive, system- level understanding of cellular behaviour. In this way, it addresses one of the greatest challenges faced by contemporary biology, which is to compre- hend the function of complex biological systems. Systems biology combines various methods that originate from scientific disciplines such as molecu- lar biology, chemistry, engineering sciences, mathematics, computer science and systems theory. Systems biology, unlike “traditional” biology, focuses on high-level concepts such as: network, component, robustness, efficiency, control, regulation, hierarchical design, synchronization, concurrency, and many others. The very terminology of systems biology is “foreign” to “tra- ditional” biology, marks its drastic shift in the research paradigm and it indicates close linkage of systems biology to computer science. One of the basic tools utilized in systems biology is the mathematical modelling of life processes tightly linked to experimental practice. The stud- ies contained in this thesis revolve around a number of challenges commonly encountered in the computational modelling in systems biology. The re- search comprises of the development and application of a broad range of methods originating in the fields of computer science and mathematics for construction and analysis of computational models in systems biology. In particular, the performed research is setup in the context of two biolog- ical phenomena chosen as modelling case studies: 1) the eukaryotic heat shock response and 2) the in vitro self-assembly of intermediate filaments, one of the main constituents of the cytoskeleton. The range of presented approaches spans from heuristic, through numerical and statistical to ana- lytical methods applied in the effort to formally describe and analyse the two biological processes. We notice however, that although applied to cer- tain case studies, the presented methods are not limited to them and can be utilized in the analysis of other biological mechanisms as well as com- plex systems in general. The full range of developed and applied modelling techniques as well as model analysis methodologies constitutes a rich mod- elling framework. Moreover, the presentation of the developed methods, their application to the two case studies and the discussions concerning their potentials and limitations point to the difficulties and challenges one encounters in computational modelling of biological systems. The problems of model identifiability, model comparison, model refinement, model inte- gration and extension, choice of the proper modelling framework and level of abstraction, or the choice of the proper scope of the model run through this thesis.

Emancipating and developing learning activity: Systemic intervention and re-instrumentation in higher education.

The central theme of this thesis is the emancipation and further development of learning activity in higher education in the context of the ongoing digital transformation of our societies. It was developed in response to the highly problematic mainstream approach to digital re-instrumentation of teaching and studying practises in contemporary higher education. The mainstream approach is largely based on centralisation, standardisation, commoditisation, and commercialisation, while re-producing the general patterns of control, responsibility, and dependence that are characteristic for activity systems of schooling. Whereas much of educational research and development focuses on the optimisation and fine-tuning of schooling, the overall inquiry that is underlying this thesis has been carried out from an explicitly critical position and within a framework of action science. It thus conceptualises learning activity in higher education not only as an object of inquiry but also as an object to engage with and to intervene into from a perspective of intentional change. The knowledge-constituting interest of this type of inquiry can be tentatively described as a combination of heuristic-instrumental (guidelines for contextualised action and intervention), practical-phronetic (deliberation of value-rational aspects of means and ends), and developmental-emancipatory (deliberation of issues of power, self-determination, and growth) aspects. Its goal is the production of orientation knowledge for educational practise. The thesis provides an analysis, argumentation, and normative claim on why the development of learning activity should be turned into an object of individual|collective inquiry and intentional change in higher education, and why the current state of affairs in higher education actually impedes such a development. It argues for a decisive shift of attention to the intentional emancipation and further development of learning activity as an important cultural instrument for human (self-)production within the digital transformation. The thesis also attempts an in-depth exploration of what type of methodological rationale can actually be applied to an object of inquiry (developing learning activity) that is at the same time conceptualised as an object of intentional change within the ongoing digital transformation. The result of this retrospective reflection is the formulation of “optimally incomplete” guidelines for educational R&D practise that shares the practicalphronetic (value related) and developmental-emancipatory (power related) orientations that had been driving the overall inquiry. In addition, the thesis formulates the instrumental-heuristic knowledge claim that the conceptual instruments that were adapted and validated in the context of a series of intervention studies provide means to effectively intervene into existing practise in higher education to support the necessary development of (increasingly emancipated) networked learning activity. It suggests that digital networked instruments (tools and services) generally should be considered and treated as transient elements within critical systemic intervention research in higher education. It further argues for the predominant use of loosely-coupled, digital networked instruments that allow for individual|collective ownership, control, (co-)production, and re-use in other contexts and for other purposes. Since the range of digital instrumentation options is continuously expanding and currently shows no signs of an imminent slow-down or consolidation, individual and collective exploration and experimentation of this realm needs to be systematically incorporated into higher education practise.
