"How are actions initiated by the human brain when there is no external sensory cue or other immediate imperative? How do subtle ongoing interactions within the brain and between the brain, body, and sensory context influence the spontaneous initiation of action? How should we approach the problem of trying to identify the neural events that cause spontaneous voluntary action? Much is understood about how the brain decides between competing alternatives, leading to different behavioral responses. But far less is known about how the brain decides "when" to perform an action, or "whether" to perform an action in the first place, especially in a context where there is no sensory cue to act such as during foraging. This project seeks to open a new chapter in the study of spontaneous voluntary action building on a novel hypothesis recently introduced by the applicant (Schurger et al, PNAS 2012) concerning the role of ongoing neural activity in action initiation. We introduce brain-behavior forecasting, the converse of movement-locked averaging, as an approach to identifying the neurodynamic states that commit the motor system to performing an action "now", and will apply it in the context of information foraging. Spontaneous action remains a profound mystery in the brain basis of behavior, in humans and other animals, and is also central to the problem of asynchronous intention-detection in brain-computer interfaces (BCIs). A BCI must not only interpret what the user intends, but also must detect "when" the user intends to act, and not respond otherwise. This remains the biggest challenge in the development of high-performance BCIs, whether invasive or non-invasive. This project will take a systematic and collaborative approach to the study of spontaneous self-initiated action, incorporating computational modeling, neuroimaging, and machine learning techniques towards a deeper understanding of voluntary behavior and the robust asynchronous detection of decisions-to-act."

The human kind is witnessing an escalation of obesity-related health problems such as cardiovascular diseases and type 2 diabetes. A recent groundbreaking study revealed adiponectin receptors (ADIPOR) as key targets for treating such obesity-related diseases. Indeed, the modulation of this integral membrane protein by small molecules agonists ameliorates diabetes and prolongs lifespan of genetically obese rodent model. Despite these exciting results and the importance of ADIPOR in human physiology, there is a complete lack of knowledge of ADIPOR mechanisms of action and pharmacology. This is mainly due to the challenges associated with the characterization of membrane protein structure and function. To fill this gap of knowledge and based on my extensive experience in membrane protein biology, I propose here to characterize the the proximal signaling pathways associated with ADIPOR activation as well as the molecular and structural mechanisms of ADIPOR activation. We will develop an innovative integrated strategy combining state-of-the-art molecular and structural pharmacology approaches including 1) molecular analyses of ADIPOR network of interaction using resonance energy transfer measurement in living cells and a proteomic analysis and 2) structural analyses of ADIPOR and signaling complexes using biophysics and X-ray crystallography. Our data will have a major impact on drug discovery for treating obesity-related diseases as it will enable the application of structure-based drug design and in silico screening for the molecular control of ADIPOR activity. The proposed high-risk endeavor of obtaining structural data on these atypical membrane signaling complexes is a new direction both for my career and for the field of adiponectin biology; the exceptionally high gain from these studies fully justifies the risks; the feasibility of this project is supported by my recent success in membrane protein pharmacology, biochemistry, biophysics and crystallography.

AFRIGOS investigates the process of 'respacing' Africa, a political drive towards regional and continental integration, on the one hand, and the re-casting of Africa's engagement with the global economy, on the other. This is reflected in unprecedented levels of investment in physical and communications infrastructure, and the outsourcing of key functions of Customs, Immigration and security agencies. AFRIGOS poses the question of how far respacing is genuinely forging institutions that are facilitating or obstructing the movement of people and goods; that are enabling or preventing urban and border spaces from being more effectively and responsively governed; and that take into account the needs of African populations whose livelihoods are rooted in mobility and informality. The principal research questions are approached through a comparative study of port cities, border towns and other strategic nodes situated along the busiest transport corridors in East, Central, West and Southern Africa. These represent sites of remarkable dynamism and cosmopolitanism, which reflects their role in connecting African urban centres to each other and to other global cities. AFRIGOS considers how governance 'assemblages' are forged at different scales and is explicitly comparative. It works through 5 connected Streams that address specific questions: 1. AGENDA-SETTING is concerned with policy (re-)formulation. 2. PERIPHERAL URBANISM examines governance in border towns and port cities. 3. BORDER WORKERS addresses everyday governance emerging through the interaction of officials and others who make their livelihoods from the border. 4. CONNECTIVE INFRASTRUCTURE looks as the transformative effects of new technologies. 5. PEOPLE & GOODS IN MOTION traces the passage of people and goods and the regimes of regulation to which they are subjected. AFRIGOS contributes to interdisciplinary research on borderland studies, multi-level governance and the everyday state.

This research proposal explores the political economy of international development assistance (aid) directed towards social expenditures, examined through the lens of a particular financial quandary that has been ignored in the literature despite having important economic and political repercussions. The quandary is that aid cannot be directly spent on expenditures denominated in domestic currency. Instead, aid needs to be first converted into domestic currency whereas the foreign exchange provided is used for other purposes, resulting in a process prone to complex politics regarding domestic monetary policy and spending commitments. The implications require a serious rethink of many of the accepted premises in the political economy of aid and related literatures. It is urgent to engage in this rethinking given tensions between two dynamics in the current global political economy: a tightening financial cycle facing developing countries versus an increasing emphasis in international development agendas of directing aid towards social expenditures. The financial quandary might exacerbate these tensions, restricting recipient government policy space despite donor commitments of respecting national ownership. The proposed research examines these implications through the emerging social protection agenda among donors, which serves as an ideal policy case given that social protection expenditures are almost entirely based on domestic currency. This will be researched through a mixed-method comparative case study of six developing countries, combining quantitative analysis of balance of payments and financing constraints with qualitative process tracing based on elite interviews and documentary research. The objective is to re-orient our thinking on these issues for a deeper appreciation of the systemic political and economic challenges facing global redistribution towards poorer countries, particularly with respect to the forthcoming Sustainable Development Goals.
