Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction
Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction SEYEDEHREZVAN FARAHIBOZORG SELWYN COLLEGE MRC COGNITION AND BRAIN SCIENCES UNIT SCHOOL OF CLINICAL MEDICINE UNIVERSITY OF CAMBRIDGE This dissertation is submitted for the degree of Doctor of Philosophy February 2018 Uncovering Dynamic Semantic Networks in the Brain Using Novel Approaches for EEG/MEG Connectome Reconstruction Seyedehrezvan Farahibozorg The current thesis addresses some of the unresolved predictions of recent models of the semantic brain system, such as the hub-and-spokes model. In particular, we tackle different aspects of the hypothesis that a widespread network of interacting heteromodal (hub(s)) and unimodal (spokes) cortices underlie semantic cognition. For this purpose, we use connectivity analyses, measures of graph theory and permutation-based statistics with source reconstructed Electro- /MagnetoEncephaloGraphy (EEG/MEG) data in order to track dynamic modulations of activity and connectivity within the semantic networks while a concept unfolds in the brain. Moreover, in order to obtain more accurate connectivity estimates of the semantic networks, we propose novel methods for some of the challenges associated with EEG/MEG connectivity analysis in source space. We utilised data-driven analyses of EEG/MEG recordings of visual word recognition paradigms and found that: 1) Bilateral Anterior Temporal Lobes (ATLs) acted as potential processor hubs for higher- level abstract representation of concepts. This was reflected in modulations of activity by multiple contrasts of semantic variables; 2) ATL and Angular Gyrus (AG) acted as potential integrator hubs for integration of information produced in distributed semantic areas. This was observed using Dynamic Causal Modelling of connectivity among the main left-hemispheric candidate hubs and modulations of functional connectivity of ATL and AG to semantic spokes by word concreteness. -
What Does Semantic Tiling of the Cortex Tell Us About Semantics? MARK ⁎ Lawrence W
Neuropsychologia 105 (2017) 18–38 Contents lists available at ScienceDirect Neuropsychologia journal homepage: www.elsevier.com/locate/neuropsychologia What does semantic tiling of the cortex tell us about semantics? MARK ⁎ Lawrence W. Barsalou University of Glasgow, UK ARTICLE INFO ABSTRACT Keywords: Recent use of voxel-wise modeling in cognitive neuroscience suggests that semantic maps tile the cortex. Semantics Although this impressive research establishes distributed cortical areas active during the conceptual processing Conceptual processing that underlies semantics, it tells us little about the nature of this processing. While mapping concepts between Neural encoding and decoding Marr's computational and implementation levels to support neural encoding and decoding, this approach ignores Multi-voxel pattern analysis Marr's algorithmic level, central for understanding the mechanisms that implement cognition, in general, and Explanatory levels conceptual processing, in particular. Following decades of research in cognitive science and neuroscience, what Cognitive mechanisms do we know so far about the representation and processing mechanisms that implement conceptual abilities? Most basically, much is known about the mechanisms associated with: (1) feature and frame representations, (2) grounded, abstract, and linguistic representations, (3) knowledge-based inference, (4) concept composition, and (5) conceptual flexibility. Rather than explaining these fundamental representation and processing mechanisms, semantic tiles simply provide a trace of their activity over a relatively short time period within a specific learning context. Establishing the mechanisms that implement conceptual processing in the brain will require more than mapping it to cortical (and sub-cortical) activity, with process models from cognitive science likely to play central roles in specifying the intervening mechanisms. -

Cognitax Tool Grammar: Re-factoring the Generative Program A pervasive action dimension for linguistic description, theory and models 12 Lawrence R. Smith (Former Associate Professor of Linguistics) [email protected] Working Version 16.2 This is a preliminary and frequently changing dynamic document responsive to reader critique and is likely not the latest version available by contacting the author. (Note the title has changed.3) The later version always supersedes the earlier and typically may include major revisions. Comments and challenges are welcome for future versions. The extended version under development is freely available on request from the author. 1 We are indebted for the incisive comments of readers who suggested constructive improvements even as the ideas presented here were sometimes at considerable variance with their own current working frameworks. We owe special thanks to the following for comments on either parts or the whole of this work: John Hewson, Paul Postal, Vit Bubenik, Pieter Seurens and Willem de Reuse. 2We had considered an alternative title for this paper since it seeks to explain malformation: “A Review of Verbal Misbehavior” 3 From version 12.9 ‘Cognitax’ replaces ‘Pragmatax’ to clarify that Tool Grammar is distinct from pragmatics, as well as separate work that may refer to grammatical tools. Both were absent from the title in an earlier version. 1 Operative Motivating Hypotheses of Tool Grammar 1. There exists an empirically evident necessity for representation of linguistic structural action intent which has been generally overlooked in the theory of language, including centralized configurational syntax in the generative program. 2. Linguistic structural action intent extends the basic Chomskyan focus on linguistic creativity (unbounded generation from finite means) to a new level of representation useful for explaining and constraining the inventive means by which the species- specific features of human language are effected. -

A major obstacle for domain experts who want to build a metamodel is that they must master two radically different languages: an object-oriented, MOF-compliant, modeling language to capture the domain structure and first order logic (the Object Constraint Language) for the definition of well-formedness rules. -
WOMEN TECHNOLOGISTS COUNT Recommendations and Best Practices to Retain Women in Computing
WOMEN TECHNOLOGISTS COUNT Recommendations and Best Practices to Retain Women in Computing ANITA BORG INSTITUTE SOLUTIONS SERIES TABLE OF CONTENTS Foreword . 1 Introduction . 2 Leadership and Accountability . 5 Corporate Culture Built for Innovation . 7 Support Networks and Communities . 11 Organizational Infrastructure and Policies . 18 Conclusion . 21 Endnotes . 22 FOREWORD ver the past 15 years, as the Anita Borg Institute has worked to improve the representation and advancement of women in computing, we’ve learned how important it is to retain women in the technical Ocareer pipeline . We know from our work with organizations that turnover among women in technology is a significant problem . Companies recognize that they cannot afford to lose valuable talent, but making a tangible impact on attrition levels can be challenging . Attrition begins when some women struggle in the transition from college to their first technical position in industry . For those who stay initially, the mid level is an especially critical “make or break” point . Many mid-level women leave the technical track to become managers . Others switch companies or step away from technology altogether . Those who advance to senior technical roles face many obstacles as they work toward the top tiers of technical leadership . Keeping women in the technical workforce matters . Teams that have a diversity of perspective, including gender, improve innovation and, ultimately, financial performance . It is in the best interest of technology companies to retain women who are committed to inventing technology and making a contribution in their fields . To institute real change in the workplace, employees throughout the organization need to understand that including people with a broad range of perspective, background and gender is a business imperative . -

Automatic Translation of OCL Meta-Level Constraints Into Java Meta-Programs
Automatic Translation of OCL Meta-Level Constraints into Java Meta-programs Sahar Kallel, Chouki Tibermacine, Bastien Tramoni, Christophe Dony and Ahmed Hadj Kacem Abstract In order to make explicit and tangible their design choices, software de- velopers integrate, in their applications’ models, constraints that their models and their implemetations should satisfy. Various environments enable constraint check- ing during the modeling stage, but in most cases they do not generate code that would enable the checking of these constraints during the implementation stage. It turns out that this is possible in a number of cases. Environments that provide this functionality only offer it for functional constraints (related to the states of objects in applications) and not for architectural ones (related to the structure of applications). Considering this limitation, we describe in this paper a system that generates metaprograms starting from architecture constraints, written in OCL at the metamodel level, and associated to a specific UML model of an application. These metaprograms enable the checking of these constraints at runtime.
