FYI ------------------------ -------- Original Message -------- Subject: PhD scholarships, Heidelberg University Date: Tue, 5 Jul 2011 22:37:26 +0200 From: Sebastian Padó <pado(a)cl.uni-heidelberg.de> Reply-To: Sebastian Padó <pado(a)cl.uni-heidelberg.de> To: researchers(a)pascal-network.org 5 PhD scholarships in Computational Linguistics: "Semantics beyond the sentence" (Date: July 5th 2011, Deadline: July 31st) We are soliciting applications for 5 PhD scholarships (EUR 1310 per month, tax-free) within the research initiative "Coherence in Language Processing: Semantics Beyond the Sentence". They are associated with the Graduate Program "Semantic Processing", jointly organized by the Computational Linguistics Department (ICL) at Heidelberg University [1] and the NLP Group at HITS gGmbH [2] in Heidelberg, Germany. The scholarships are available from October 1st, 2011, and will run three years (dependent on positive evaluations after the first and second years). The goal of the research initiative "Coherence in Language Processing: Semantics Beyond the Sentence" is to investigate computational models of semantic phenomena at the discourse level by (a) analysing semantic phenomena at the discourse level and represent them; (b) using these representatons to improve semantic analysis; (c) evaluating (a) and (b) in NLP applications, including SMT. See [3] for details. Candidates should have a strong background in computational linguistics and possess a Masters or a Diploma degree in either Computational Linguistics or Computer Science/Linguistics with a specialization in Natural Language Processing. Experience with machine learning, corpus-based methods and statistics is a plus. Strong programming skills (Java, C++, or Python) are required. Scholarship holders will become members of the graduate program "Semantic Processing" [4]. They will participate in a PhD colloquium and may attend lectures at the university and the Heidelberg Graduate School "MathComp" [5]. The graduate program provides a lively research environment with about ten PhD students already enrolled. Interdisciplinary research links exist to computer science, linguistics, and other disciplines. Applications should include a research statement indicating the candidates' interests and plans (which should fall into the area outlined above), university transcripts and a CV. They should also indicate a preference for a primary supervisor matching their plans (Anette Frank, Sebastian Pado, Stefan Riezler, Michael Strube). For more details, see the links below.

YNiC seminar 7th July
by Rebecca E Millman 04 Jul '11

04 Jul '11

Dear Users This Thursday (4-5 pm) there will be a project proposal presentation given by Rich Harris. The title of Rich's talk is "The neural representation of perceived changes in facial expression". Please see below for the talk abstract. Everyone is welcome to attend and refreshments will be provided. Best wishes Rebecca Abstract: How the brain represents different aspects of faces remains controversial. This experiment will present participants with stimuli drawn from morphed continua between two different emotional facial expressions. In paired presentations, a second face could: (1) be identical to the first; (2) share the perceived expression category but differ physically along the morphed continuum (within-expression change); (3) differ physically by the same distance along the continuum but in a direction that leads participants to classify the face pairs as showing expressions of different basic emotions (between-expression change). Using an fMR-adaptation paradigm, our aim is to reveal regions of the brain whose activity corresponds to our sensitivity to changes in facial expression. -- Dr. Rebecca E.

Matlab / SPM versions
by Mark Hymers 30 Jun '11

30 Jun '11

Hi, We've added Matlab 7.12 (R2011a) to the YNiC systems. The default has not yet changed and remains 7.10 (R2010a). Details of the supported versions are at: https://www.ynic.york.ac.uk/doc/ITPages/FAQ/Misc/SupportedVersions#Matlab At the same time, we've updated SPM8 to the latest revision which is 8+svn4290. Can people please test the new Matlab version as we'll change the default in September unless any major issues are found. We'll also be looking to withdraw Matlab 7.8 in September (as previously announced) as part of a major set of software upgrades. More on this later.

YNiC seminar today
by rem 30 Jun '11

30 Jun '11

Dear Users Today (4-5 pm in YNiC) there will be a project proposal presentation by Carin Whitney. The title of the project is "Investigating semantic cognition with MEG, fMRI and TMS". Please see below for the talk abstract. Everyone is welcome to attend and refreshments will be provided after the talk. Best wishes Rebecca Abstract: Beth Jefferies, Carin Whitney, Piers Cornelissen and Andy Ellis This project investigates how semantic cognition – referring to our ability to understand the meaning of words, pictures, faces, sounds, and smells – is represented in the brain. We will focus on semantic control, which is one of two principal components of semantic cognition and relates to executive mechanisms that enable us to retrieve and select conceptual knowledge according to the current task or context. Research has been plentiful in describing the spatial extent of the brain regions that underpin semantic control, and has identified a distributed fronto-temporo-parietal network. However, it remains largely unknown how this system is organised (i.e., what the specific functions of each component are) and how well they interact. In the proposed project, we will apply a novel approach to investigate these questions by combining MEG with TMS and fMRI. In particular, we will use MEG to track neural activity, allowing us to generate predictions about likely patterns of communication within the semantic control network and its relation to other components of semantic cognition (i.e., brain areas that encode conceptual knowledge). Follow-up TMS will then be used to impair brain functioning at specific time points to prove causality. Equivalent fMRI data – taken from the same participants and tasks – will guide coil positioning for TMS and act as a spatial localiser for MEG. The project hence aims to establish a neural model of semantic cognition that is based on convergent evidence across different methods, generating potentially strong conclusions about how meaning retrieval is achieved. -- ************************************************************************ Dr. Rebecca E.

Dear Users Today (4-5 pm in YNiC) there will be a talk by Prof. Peter Redgrave from the University of Sheffield. http://www.sheffield.ac.uk/psychology/staff/academic/peter-redgrave The title of Prof. Redgrave's talk is "Goal-directed and habitual control in the basal ganglia: implications for Parkinson's disease". Please see below for the talk abstract. Everyone is welcome to attend and refreshments will be provided after the talk. Best wishes Rebecca Abstract: Progressive loss of the ascending dopaminergic projection in the basal ganglia is a fundamental pathological feature of Parkinson’s disease. Studies in animals and humans have identified spatially segregated functional territories in the basal ganglia for the control of goal-directed and habitual actions. In patients with Parkinson’s disease the loss of dopamine is predominantly in the posterior putamen, a region of the basal ganglia associated with the control of habitual behaviour. These patients may therefore be forced into a progressive reliance on the goal-directed mode of action control that is mediated by comparatively preserved processing in rostro-medial striatum. Thus, in addition of the loss of habits, the behavioural difficulties of Parkinson patients may also be subject to distorting output signals from habitual control circuits which impede the expression of goal-directed action. -- ************************************************************************ Dr. Rebecca E.

MEG Analysis Code Changes
by Mark Hymers 13 Jun '11

13 Jun '11

Hi, We have just pushed some core changes to the YNiC NAF Beamforming code. The change is that nafEpochRejection will no longer produce what have become known as "Epoch Rejection Files" but will instead produce "Slice Rejection Files". "Epoch Rejection File" are simply a list of epochs of data which should be rejected during analysis due to artifacts. This can be problematic, as if you change your pre-trigger or epoch duration, the timings of the epochs will move around and you will reject data you didn't mean to, whilst not rejecting the data around your artifacts. The replacement for these are "Slice Rejection Files". These are a list of slice ranges containing bad data - simply a list of comma separated slice ranges; one per line. The analysis (beamformer) code itself will continue to accept Epoch Rejection Files which are listed in YAML files for analysis, but will produce "Deprecation Warnings" to remind you that you should consider converting. If you wish to convert an existing Epoch Rejection File to a Slice Rejection File, you can do one of the following: * Use the nafEpochRejectToSliceReject tool (documented at /mnt/common/naf/naf-doc/userref/scripts/nafEpochRejectToSliceReject.html ) * Load the Epoch Rejection file into nafEpochRejection using the -e flag and it will output a slice rejection file. * Load you study into the Study Definer Tool (nafStudyDefiner) and it will offer to convert all epoch rejection files into slice rejection files and update the YAML file for you at the same time. Although the nafEpochRejection and nafStudyDefiner tool will still read Epoch Rejection Files (to perform conversions), they will no longer allow you to edit or output them; they will only work with and output slice rejection files. It should be noted that internally, all of the code now converts Epoch Rejection Files to Slice Rejection Files. This means that strictly speaking, if you have overlapping epochs, a single epoch number in an epoch rejection may now result in more than one epoch being rejected. This should be a rare corner case and if you want to fully understand and see what is going on, you can use the nafShowEpochs tool to list the epochs you have and, if a epoch or slice rejection file is present in your YAML file, whether or not they will be rejected. This is one of the final big changes before we make the NAF tools available by default on the system. More on that soon. Thanks, Mark -- Mark Hymers York Neuroimaging Centre

Dear Users Today (4-5 pm in YNiC) there will be a YNiC project proposal presentation given by Chris Racey. The title of the talk is "The effects of parametrically manipulating view exposure range on representational invariance in object selective cortex". Please see the abstract below. Everyone is welcome to attend. N.B. The starting time of the YNiC seminars will be 4 pm this term. Best wishes Rebecca *Abstract* Previously we have carried out two experiments in which view shift of objects and landscape scenes was parametrically manipulated. In both experiments participants viewed blocks of stimuli changing in view by 0, 5, 10, and 15°. Different levels of adaptation across these view shift conditions allow us to derive a measure of view sensitivity for any given voxel or region. We were able to show variation in the degree of view sensitivity between category selective regions for both objects and landscape stimuli. Our previous work has shed new light on how category specific visual information is processed and represented during perception. However, it is not yet clear what the effect of object learning and long term storage is on these ventral stream representations. Previous research on this issue is limited, and there have been few studies investigating the effects of prior learning on neural adaptation. We aim to apply our parametric manipulation of view shift paradigm during an encoding experiment with unfamiliar objects prior to scanning. Participants will under training, and learn to recognise objects where their range of view exposure will vary parametrically, from 0°, 10°, and 20°. In the scanner, all of the stimuli will be presented from previously unseen views in an fMR-adaptation block design, with blocks of images shifting in view in 10° steps. For each pre-exposure condition, the presentation conditions in the scanner will be identical, and any differences across conditions must be due to differences during the encoding of items. We predict that objects learned with a greater range of views will be associated with richer, more invariant, representations, and show greater degrees of invariant adaptation than objects learned under a narrower range of views. -- Dr. Rebecca E.

FYI --------------------- We are looking for two bright and motivated researchers to work on a research project in which we will use *brain imaging and advanced brain decoding methods to investigate the neural basis of deviant mental representations in neurodevelopmental disorders such as autism, dyslexia, and dyscalculia*. This project is an interdisciplinary collaboration between the Laboratory of Biological Psychology (Hans Op de Beeck), the Parenting and Special Education Research Group (Bert De Smedt), and Child Psychiatry (Jean Steyaert, Bart Boets), all part of the University of Leuven (K.U.Leuven) in Belgium. We offer one PhD position and one Post-doc position. Eligible candidates should have or should soon obtain a master’s degree (for the PhD position) and a PhD (for the postdoc position) in a relevant field such as neuroscience, psychology, psychiatry, neurobiology, or medical engineering. Specific positive points for the evaluation will be experience with brain imaging (in particular functional magnetic resonance imaging), a computational background in a relevant field (e.g., brain imaging data analysis, neural networks, etc.), and good computer skills (e.g., Matlab). A background in neurodevelopmental disorders is a plus, but not mandatory. Good English (oral and written) communicative skills are necessary. The two positions are full-time, for a period of 4 years (PhD position) and 2-3 years (postdoc), and start in October 2011. The two positions are strongly research oriented, and teaching and/or administration load will be minimal. The research will be embedded in a very stimulating environment with state-of-the-art technical facilities and with ample opportunities for interaction with experts on neurodevelopmental disorders and brain imaging. The K.U.Leuven is consistently ranked within the top of European Universities and is located in the city of Leuven, which has an strong international appeal. For more information about our university, please visit http://www.kuleuven.be/about/ Formal applications should be sent by email to Hans Op de Beeck, and should include a scientific CV (mentioning past research positions and education, and publications), motivation letter, and the names and contact information of 2 senior researchers that are willing to write a recommendation letter if necessary (no letters have to be sent yet). Application deadline is June 20^th 2011. For further information please contact Hans Op de Beeck (hans.opdebeeck(a)psy.kuleuven.be <mailto:hans.opdebeeck@psy.kuleuven.be>), Bert De Smedt (Bert.DeSmedt(a)ped.kuleuven.be <mailto:Bert.DeSmedt@ped.kuleuven.be>), or Bart Boets (Bart.Boets(a)ped.kuleuven.be <mailto:Bart.Boets@ped.kuleuven.be>).

YNiC seminar 26th May
by Rebecca E Millman 22 May '11

22 May '11

Dear Users This Thursday (4-5 pm in YNiC) there will be a YNiC project proposal presentation given by Chris Racey. The title of the talk is "The effects of parametrically manipulating view exposure range on representational invariance in object selective cortex". Please see the abstract below. Everyone is welcome to attend. N.B. The starting time of the YNiC seminars will be 4 pm this term. Best wishes Rebecca *Abstract* Previously we have carried out two experiments in which view shift of objects and landscape scenes was parametrically manipulated. In both experiments participants viewed blocks of stimuli changing in view by 0, 5, 10, and 15°. Different levels of adaptation across these view shift conditions allow us to derive a measure of view sensitivity for any given voxel or region. We were able to show variation in the degree of view sensitivity between category selective regions for both objects and landscape stimuli. Our previous work has shed new light on how category specific visual information is processed and represented during perception. However, it is not yet clear what the effect of object learning and long term storage is on these ventral stream representations. Previous research on this issue is limited, and there have been few studies investigating the effects of prior learning on neural adaptation. We aim to apply our parametric manipulation of view shift paradigm during an encoding experiment with unfamiliar objects prior to scanning. Participants will under training, and learn to recognise objects where their range of view exposure will vary parametrically, from 0°, 10°, and 20°. In the scanner, all of the stimuli will be presented from previously unseen views in an fMR-adaptation block design, with blocks of images shifting in view in 10° steps. For each pre-exposure condition, the presentation conditions in the scanner will be identical, and any differences across conditions must be due to differences during the encoding of items. We predict that objects learned with a greater range of views will be associated with richer, more invariant, representations, and show greater degrees of invariant adaptation than objects learned under a narrower range of views. -- ************************************************************************ Dr. Rebecca E.
