Summary Membranes are key materials in our life. Nature offers high performance membranes relying on a parallel local regulation of nanopore structure, functional placement, membrane composition and architecture. Existing technological membranes are key materials in separation, recycling, sensing, energy conversion, being essential components for a sustainable future. But their performance is far away from their natural counterparts. One reason for this performance gap is the lack of 3D nanolocal control in membrane design. This applies to each individual nanopore but as well to the membrane architecture. This proposal aims to implement 3D printing (additive manufacturing, top down) and complex near-field and total internal reflection (TIR) high resolution microscopy induced polymer writing (bottom up) to nanolocally control in hierarchical nanoporous membranes spatially and independent of each other: porosity, pore functionalization, membrane architecture, composition. This disruptive technology platform will make accessible to date unachieved, highly accurate asymmetric nanopores and multifunctional, hierarchical membrane architecture/ composition and thus highly selective, directed, transport with tuneable rates. 3D-FNPWriting will demonstrate this for the increasing class of metal nanoparticle/ salt pollutants aiming for tuneable, selective, directed transport based monitoring and recycling instead of size-based filtration, accumulation into sewerage and distribution into nature. Specifically, the potential of this disruptive technology with respect to transport design will be demonstrated for a) a 3D-printed in-situ functionalized nanoporous fiber architecture and b) a printed, nanolocally near-field and TIR-microscopy polymer functionalized membrane representing a thin separation layer. This will open systematic understanding of nanolocal functional control on transport and new perspectives in water/ energy management for future smart industry/ homes.

Summary "The twin concepts of sustainability and conservation that are so pivotal within current debates regarding economic development and biodiversity protection both contain an inherent temporal dimension, since both refer to the need to balance short-term gains with long-term resource maintenance. Proponents of resilience theory and of development based on ‘indigenous knowledge’ have thus argued for the necessity of including archaeological, historical and palaeoenvironmental components within development project design. Indeed, some have argued that archaeology should lead these interdisciplinary projects on the grounds that it provides the necessary time depth and bridges the social and natural sciences. The project proposed here accepts this logic and endorses this renewed contemporary relevance of archaeological research. However, it also needs to be admitted that moving beyond critiques of the misuse of historical data presents significant hurdles. When presenting results outside the discipline, for example, archaeological projects tend to downplay the poor archaeological visibility of certain agricultural practices, and computer models designed to test sustainability struggle to adequately account for local cultural preferences. This field will therefore not progress unless there is a frank appraisal of archaeology’s strengths and weaknesses. This project will provide this assessment by employing a range of established and groundbreaking archaeological and modelling techniques to examine the development of two east Africa agricultural systems: one at the abandoned site of Engaruka in Tanzania, commonly seen as an example of resource mismanagement and ecological collapse; and another at the current agricultural landscape in Konso, Ethiopia, described by the UN FAO as one of a select few African “lessons from the past”. The project thus aims to assess the sustainability of these systems, but will also assess the role archaeology can play in such debates worldwide."

Summary Antibiotics have contributed to a tremendous increase in human well-being, saving many millions of lives. However, antibiotics become obsolete the more they are used as selection pressure promotes the development of resistant bacteria. The World Health Organization has proclaimed antibiotic resistance as a major global threat to public health. Today, 700,000 deaths per year are due to untreatable infections. To win the battle against antibiotic resistance, new policies affecting the supply and demand of existing and new drugs must be designed. I propose new research to identify and evaluate feasible and effective demand-side policy interventions targeting the relevant decision makers: physicians and patients. ABRSEIST will make use of a broad econometric toolset to identify mechanisms linking antibiotic resistance and consumption exploiting a unique combination of physician-patient-level antibiotic resistance, treatment, and socio-economic data. Using machine learning methods adapted for causal inference, theory-driven structural econometric analysis, and randomization in the field it will provide rigorous evidence on effective intervention designs. This research will improve our understanding of how prescribing, resistance, and the effect of antibiotic use on resistance, are distributed in the general population which has important implications for the design of targeted interventions. It will then estimate a structural model of general practitioners’ acquisition and use of information under uncertainty about resistance in prescription choice, allowing counterfactual analysis of information-improving policies such as mandatory diagnostic testing. The large-scale and structural econometric analyses allow flexible identification of physician heterogeneity, which ABRSEIST will exploit to design and evaluate targeted, randomized information nudges in the field. The result will be improved rational use and a toolset applicable in contexts of antibiotic prescribing.

Call Details Starting Grant (StG), SH4, ERC-2013-StG
Summary "By 2040, the European population aged over 60 will rise to 290 million, with those estimated to have dementia to 15.9 million. These dramatic demographic changes will pose huge challenges to health care systems, hence a detailed understanding of age-related cognitive and neurobiological changes is essential for helping elderly populations maintain independence. However, while existing research into cognitive ageing has carefully characterised developmental trajectories of functions such as memory and processing speed, one key cognitive ability that is particularly relevant to everyday functioning has received very little attention: In surveys, elderly people often report substantial declines in navigational abilities such as problems with finding one’s way in a novel environment. Such deficits severely restrict the mobility of elderly people and affect physical activity and social participation, but the underlying behavioural and neuronal mechanisms are poorly understood.
In this proposal, I will take a new approach to cognitive ageing that will bridge the gap between animal neurobiology and human cognitive neuroscience. With support from the ERC, I will create a team that will characterise the mechanisms mediating age-related changes in navigational processing in humans. The project will focus on three structures that perform key computations for spatial navigation, form a closely interconnected triadic network, and are particularly sensitive to the ageing process. Crucially, the team will employ an interdisciplinary methodological approach that combines mathematical modelling, brain imaging and innovative data analysis techniques with novel virtual environment technology, which allows for rigorous testing of predictions derived from animal findings. Finally, the proposal also incorporates a translational project aimed at improving spatial mnemonic functioning with a behavioural intervention, which provides a direct test of functional relevance and societal impact."

Summary I suggest that perceptions of diversity and disagreement voiced in the on-line political discussion may play a key role in mobilizing citizens to voice their views and take action in authoritarian regimes. The empirical focus is the Chinese Internet. Subjective perceptions of group discussion among participants can significantly differ from the objective content of the discussion. These perceptions can have an independent effect on political engagement. Novel is also that I will study which technological settings (blogs, Weibo (Twitter), public hearings, etc) facilitate these perceptions.
I will address these novel issues by specifying the conditions and causal mechanisms that facilitate the rise of online public opinion. As an expansion to prior work, I will study passive in addition to active participants in online discussion. This is of particular interest because passive participants outnumber active participants.
My overall aim is to deepen our knowledge of how participants experience online political discussion in stabilizing or destabilizing authoritarian rule. To this end, I propose to work with one post-doc and two PhD research assistants on four objectives: Objective 1 is to explore what kinds of people engage in online discussions and differences between active and passive participants. Objective 2 is to understand how the technological settings that create the conditions for online discussion differ from each other. Objective 3 is to assess how active and passive participants see the diversity and disagreement in the discussion in these settings. Objective 4 is to assess whether citizens take action upon online political discussion depending on how they see it.
I will produce the first nationally representative survey on the experiences of participants in online political discussion in China. In addition to academics, this knowledge is of interest to policy-makers, professionals, and journalists aiming to understand authoritarian politics and media

Project Benefit-sharing for an equitable transition to the green economy - the role of law

Call Details Starting Grant (StG), SH2, ERC-2013-StG
Summary Can benefit-sharing address the equity deficit within the green economy? This project aims to investigate benefit-sharing as an under-theorised and little-implemented regulatory approach to the equity concerns (disregard for the special circumstances of developing countries and of indigenous peoples and local communities) in transitioning to the green economy.
Although benefit-sharing is increasingly deployed in a variety of international environmental agreements and also in human rights and corporate accountability instruments, no comprehensive account exists of its conceptual and practical relevance to equitably address global environmental challenges. This project will be the first systematic evaluation of the conceptualisations and operationalisations of benefit-sharing as a tool for equitable change through the allocation among different stakeholders of economic and also socio-cultural and environmental advantages arising from natural resource use.
The project will combine a comparative study of international law with empirical legal research, and include an inter-disciplinary study integrating political sociology in a legal enquiry on the role of “biocultural community protocols” that articulate and implement benefit-sharing at the intersection of international, transnational, national and indigenous communities’ customary law (global environmental law).
The project aims to: 1. develop a comprehensive understanding of benefit-sharing in international law; 2. clarify whether and how benefit-sharing supports equity and the protection of human rights across key sectors of international environmental regulation (biodiversity, climate change, oceans, food and agriculture) that are seen as inter-related in the transition to the green economy; 3. understand the development of benefit-sharing in the context of global environmental law; and
4. clarify the role of transnational legal advisors (NGOs and bilateral cooperation partners) in the green economy.

Summary This project investigates the cross-fertilisation of Anglo/American and German literature and film during the Allied Occupation of Germany. It will be the first study to survey the cultural landscape of the British and American zones of Occupied Germany in any detail. By doing so it will offer a new interpretative framework for postwar culture, in particular in three areas: the history of the Allied Occupation of Germany; the history of postwar Anglophone and Germanophone literature (arguing the two were more intertwined than has previously been suggested); and the history of the relationship between postwar and Cold War. Combining Anglo-American and German literature and film history with critical analysis, cultural history and life-writing, this is a necessarily ambitious, multidisciplinary study which will open up a major new field of research.

Call Details Starting Grant (StG), SH5, ERC-2013-StG
Summary The global performing arts community is requiring innovative systems to: a) document, transmit and preserve the knowledge contained in choreographic-dramaturgic practices; b) assist artists with tools to facilitate their compositional processes, preferably on a collaborative basis. The existing digital archives of performing arts mostly function as conventional e-libraries, not allowing higher degrees of interactivity or active user intervention. They rarely contemplate accessible video annotation tools or provide relational querying functionalities based on artist-driven conceptual principles or idiosyncratic ontologies.
This proposal endeavours to fill that gap and create a new paradigm for the documentation of performance composition. It aims at the analysis of artists’ unique conceptual structures, by combining the empirical insights of contemporary creators with research theories from Multimodal Communication and Digital Media studies. The challenge is to design a model for a web-based collaborative platform enabling both a robust representation of performance composition methods and novel visualization technologies to support it. This can be done by analysing recurring body movement patterns and by fostering online contributions of users (a.o. performers and researchers) to the multimodal annotations stored in the platform. To accomplish this goal, two subjacent components must be developed: 1. the production of a video annotation-tool to allow artists in rehearsal periods to take notes over video in real-time and share them via the collaborative platform; 2. the linguistic analysis of a corpus of invited artists’ multimodal materials as source for the extraction of indicative conceptual structures, which will guide the architectural logics and interface design of the collaborative platform software.The outputs of these two components will generate critical case-studies to help understanding the human mind when engaged in cultural production processes.

Call Details Starting Grant (StG), SH4, ERC-2013-StG
Summary "The body is ubiquitous in perceptual experience and is central to our sense of self and personal identity. Disordered body representations are central to several serious psychiatric and neurological disorders. Thus, identifying factors which contribute to the formation and maintenance of body representations is crucial for understanding how body representation goes awry in disease, and how it might be corrected by potential novel therapeutic interventions. Several types of sensory signals provide information about the body, making the body the multisensory object, par excellence. Little is known, however, about how information from somatosensation and from vision is integrated to construct the rich body representations we all experience. This project fills this gap in current understanding by determining how the brain builds body representations (BODYBUILDING). A hierarchical model of body representation is proposed, providing a novel theoretical framework for understanding the diversity of body representations and how they interact. The key motivating hypothesis is that body representation is determined by the dialectic between two major cognitive processes. First, from the bottom-up, somatosensation represents the body surface as a mosaic of discrete receptive fields, which become progressively agglomerated into larger and larger units of organisation, a process I call fusion. Second, from the top-down, vision starts out depicting the body as an undifferentiated whole, which is progressively broken into smaller parts, a process I call segmentation. Thus, body representation operates from the bottom-up as a process of fusion of primitive elements into larger complexes, as well as from the top-down as a process of segmentation of an initially undifferentiated whole into more basic parts. This project uses a combination of psychophysical, electrophysiological, and neuroimaging methods to provide fundamental insight into how we come to represent our body."

Researcher (PI) Juha Tapani Silvanto
Host Institution (HI) THE UNIVERSITY OF WESTMINSTER LBG
Country United Kingdom
Call Details Starting Grant (StG), SH4, ERC-2013-StG
Summary "Conscious experiences normally result from the flow of external input into our sensory systems. However, our minds are also able to create conscious percepts in the absence of any sensory stimulation; these internally generated percepts are referred to as mental images, and they have many similarities with real visual percepts; consequently, mental imagery is often referred to as “seeing in the mind’s eye”. Mental imagery is also believed to be closely related to working memory, a mechanism which can maintain “offline” representations of visual stimuli no longer in the observer’s view, as both involve internal representations of previously seen visual attributes. Indeed, visual imagery is often thought of as a conscious window into the content of memory representations. Imagery, working memory, and conscious perception are thus thought to rely on very similar mechanisms. However, in everyday life we are generally able to keep apart the constructs of our imagination from real physical events; this begs the question of how the brain distinguishes internal mental images from externally induced visual percepts. To answer this question, the proposed work aims to isolate the cortical mechanisms associated uniquely with WM and imagery independently of each other and independently of the influence of external conscious percepts. Furthermore, by the use of neuroimaging and brain stimulation, we aim to determine the cortical mechanisms which keep apart internally generated and externally induced percepts, in both health and disease. This is a question of great clinical interest, as the ability to distinguish the perceived from the imagined is impoverished in psychotic disorders. In addition to revealing the mechanisms underlying this confusion, the present project aims to alleviate it in psychotic patients by the use of brain stimulation. The project will thus significantly improve our understanding of these cognitive processes and will also have clinical implications."
