Yang-Mills heatflow on gauged holomorphic maps
No full textWe study the gradient flow lines of a Yang-Mills-type functional on the space of gauged holomorphic maps whose domain is a principal bundle on a Riemann surface and the target is a Kahler Hamiltonian manifold. When the Riemann surface in the domain is compact, possibly with boundary, we prove long time existence of the gradient flow. The flow lines converge to critical points of the functional. So, there is a stratification of the space of gauged holomorphic maps that is invariant under the action of the complexified gauge group. Symplectic vortices are the zeros of the functional we study. When the Riemann surface has boundary, similar to Donaldson's result for the Hermitian Yang-Mills equations, we show that there is only a single stratum - any gauged-holomorphic map can be complex gauge transformed to a symplectic vortex. This is a version of Mundet's Hitchin-Kobayashi result on a surface with boundary.Ph. D.Includes bibliographical referencesby Sushmita Venugopala
Author Exchange
No full textAnthropologist Mukulika Banerjee and political scientist Sushmita Pati have a conversation about their recently published books set in rural Bengal and Delhi’s urban villages, respectively. They situate their analyses of the intersections between democracy, capitalism, urbanization, and globalization in events, relations, and cultures of the everyday. Their exchange offers important insights for how political subjectivities and social ties are differently constituted or, to use Banerjee’s term, “cultivated” in these two settings. The two books offer a fine-grained view of how active citizenship in rural and urban India is refracted through distinct social and institutional structures. India is home to some of the world’s largest cities while more than 900 million people continue to live in the countryside. Its democratic future is therefore inextricably tied to the evolution of political behavior and political economy in both contexts, and, as Banerjee and Pati’s joint response indicates, to how urban and rural dynamics shape each other through (but not only through) migrants and their networks.

Stable Matching Games: Manipulation via Subgraph Isomorphism
Get PDFIn this paper we consider a problem that arises from a strategic issue in the stable matching model (with complete preference lists) from the viewpoint of exact-exponential time algorithms. Specifically, we study the Stable Extension of Partial Matching (SEOPM) problem, where the input consists of the complete preference lists of men, and a partial matching. The objective is to find (if one exists) a set of preference lists of women, such that the men-optimal Gale Shapley algorithm outputs a perfect matching that contains the given partial matching. Kobayashi and Matsui [Algorithmica, 2010] proved this problem is NP-complete. In this article, we give an exact-exponential algorithm for SEOPM running in time 2^{O(n)}, where n denotes the number of men/women. We complement our algorithmic finding by showing that unless Exponential Time Hypothesis (ETH) fails, our algorithm is asymptotically optimal. That is, unless ETH fails, there is no algorithm for SEOPM running in time 2^{o(n)}. Our algorithm is a non-trivial combination of a parameterized algorithm for Subgraph Isomorphism, a relationship between stable matching and finding an out-branching in an appropriate graph and enumerating non-isomorphic out-branchings

Taming the Research Paper
Get PDFThe first-year college student’s approach to a research paper assignment can be similar to that of a wild bucking horse loose in a pasture. Librarians and classroom faculty members, on the other side of the fence, find it their role to corral these wild horses. During this experiential workshop, Hudson Valley Community College “horse whisperers,” Robert Matthews from the Marvin Library and Sushmita Chatterji from the English Department will demonstrate successful partnership techniques developed to assist students in taming these mustangs
Lessons learnt developing and deploying grading mechanisms for EiPE code-reading questions in CS1 classes
Get PDFPrevious research has identified that the ability to understand the high-level purpose of a piece of code is an important developmental skill that is harder to master than executing the same piece of code in one’s head for a given input (“code tracing”), but easier to master than writing the code. One way to help students to practice this skill in the middle ground is by asking them Explain in Plain English (EiPE) questions, where they are asked to explain the purpose of a piece of code at a high level. Prior works involving EiPE questions have used scoring rubrics that do not adequately handle the three dimensions of answer quality: correctness, level of abstraction, and ambiguity. Also, these studies have been carried out in limited experimental settings with manual grading, which did not shed light on how EiPE questions can be deployed in real world classrooms without overwhelming grading workload.
In this work, we cover both unaddressed issues. First, we describe our efforts in validating a 7-point rubric that the research group has developed for scoring student responses to EiPE questions. Second, we describe the deployment of an imperfect NLP-based automatic grading system for these EiPE responses on an exam in CS105, a large-enrollment CS1 course at the University of Illinois, finding that the auto-grader has an accuracy similar to that of TA’s who teach the course. We study allowing students to attempt an EiPE question multiple times (without penalty based on the number of attempts used) in exam settings as a strategy to mitigate potential student dissatisfaction due to the imperfect grading system mistakenly rejecting a correct answer. We also characterize common student errors, auto-grader failure, and discuss the lessons learnt in this process.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-05-01The student, Sushmita Azad, accepted the attached license on 2020-05-13 at 11:51.The student, Sushmita Azad, submitted this Thesis for approval on 2020-05-13 at 12:01.This Thesis was approved for publication on 2020-05-14 at 16:37.DSpace SAF Submission Ingestion Package generated from Vireo submission #15379 on 2020-08-25 at 17:31:24Made available in DSpace on 2020-08-26T23:58:50Z (GMT).

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
