Visualization of analytic provenance for sensemaking

Sensemaking is an iterative and dynamic process, in which people collect data relevant to their tasks, analyze the collected information to produce new knowledge, and possibly inform further actions. During the sensemaking process, it is difficult for the human’s working memory to keep track of the progress and to synthesize a large number of individual findings and derived hypotheses, thus limits the performance. Analytic provenance captures both the data exploration process and and its accompanied reasoning, potentially addresses these information overload and disorientation problems. Visualization can help recall, revisit and reproduce the sensemaking process through visual representations of provenance data. More interesting and challenging, analytic provenance has the potential to facilitate the ongoing sensemaking process rather than providing only post hoc support. This thesis addresses the challenge of how to design interactive visualizations of analytic provenance data to support such an iterative and dynamic sensemaking. Its original contribution includes four visualizations that help users explore complex temporal and reasoning relationships hidden in the sensemaking problems, using both automatically and manually captured provenance. First SchemaLine, a timeline visualization, enables users to construct and refine narratives from their annotations. Second, TimeSets extends SchemaLine to explore more complex relationships by visualizing both temporal and categorical information simultaneously. Third, SensePath captures and visualizes user actions to enable analysts to gain a deep understanding of the user’s sensemaking process. Fourth, SenseMap visualization prevents users from getting lost, synthesizes new relationship from captured information, and consolidates their understanding of the sensemaking problem. All of these four visualizations are developed using a user-centered design approach and evaluated empirically to explore how they help target users make sense of their real tasks. In summary, this thesis contributes novel and validated interactive visualizations of analytic provenance data that enable users to perform effective sensemaking.
The Opportunities and Limitations of Monopsony Power in Healthcare: Evidence from the United States and Canada

Perhaps more than any other sector of the economy, healthcare depends on government resources. As a result, many healthcare systems rely on the use of government monopsony power to decrease spending. The United States is a notable exception, where prices in large portions of the healthcare sector are set without government involvement. In this paper we examine the economic implications of a greater use of monopsony power in the United States. We present a model of monopsony power and test its predictions using price differences between the United States and Canada – a country that represents an example of a “Medicare for All” style system. Overall, we find that wage differences for medical providers across the two countries are primarily driven by the broader labor market while price difference for prescription drugs are more directly the result of buyer power. We discuss theoretical reasons why a Canadian monopsonist may be more willing to exploit its buyer power over prescription drugs rather than provider wages and why a U.S. monopsonist might not be willing to do the same

Joint Discourse-aware Concept Disambiguation and Clustering

This thesis addresses the tasks of concept disambiguation and clustering. Concept disambiguation is the task of linking common nouns and proper names in a text – henceforth called mentions – to their corresponding concepts in a predefined inventory. Concept clustering is the task of clustering mentions, so that all mentions in one cluster denote the same concept. In this thesis, we investigate concept disambiguation and clustering from a discourse perspective and propose a discourse-aware approach for joint concept disambiguation and clustering in the framework of Markov logic. The contributions of this thesis are fourfold: Joint Concept Disambiguation and Clustering. In previous approaches, concept disambiguation and concept clustering have been considered as two separate tasks (Schütze, 1998; Ji & Grishman, 2011). We analyze the relationship between concept disambiguation and concept clustering and argue that these two tasks can mutually support each other. We propose the – to our knowledge – first joint approach for concept disambiguation and clustering. Discourse-Aware Concept Disambiguation. One of the determining factors for concept disambiguation and clustering is the context definition. Most previous approaches use the same context definition for all mentions (Milne & Witten, 2008b; Kulkarni et al., 2009; Ratinov et al., 2011, inter alia). We approach the question which context is relevant to disambiguate a mention from a discourse perspective and state that different mentions require different notions of contexts. We state that the context that is relevant to disambiguate a mention depends on its embedding into discourse. However, how a mention is embedded into discourse depends on its denoted concept. Hence, the identification of the denoted concept and the relevant concept mutually depend on each other. We propose a binwise approach with three different context definitions and model the selection of the context definition and the disambiguation jointly. Modeling Interdependencies with Markov Logic. To model the interdependencies between concept disambiguation and concept clustering as well as the

On The Classification of Binary Space Shift Keying Modulation

Blind and non-cooperative classification of the modulation employed in signals originating from unknown or partly known sources has widespread applications in civilian and military contexts. One of the most recent and interesting approaches to digital modulation which has been enabled by multiantenna transceivers is the spatial modulation, where the indices of the transmit antennas activated in a given symbol period are utilized to transmit information bits. Clearly, existing modulation classification methods, designed for the identification of conventional modulation types, are not capable of classifying the family of spatially modulated signals that make use of the space dimension. In this letter, for the first time in the literature, a modulation classification method is proposed for a modulation type belonging to the family of spatial modulations: the binary space shift keying modulation.
Viewing L2 captioned videos: what's in it for the listener?

ABSTRACT Captioning is commonly used to scaffold video viewing for second language learners, with the captioning affording the learners access to authentic videos that would ordinarily be out of their reach. Ostensibly the videos are mainly shown to help improve the learners’ listening abilities. However, there is the view that the learners largely tend to just read the captions at the expense of listening to the speakers, thus doing little more than improving their reading skills. Consequently, this article examines a number of past studies to investigate whether this is the case or whether the learners’ listening may indeed benefit. A key approach to this investigation of the past research is to ascertain how the learners process the videos; there is obviously the need for the learners to listen, to some degree, for their listening abilities to develop. The investigation finds that less-proficient learners tend more to read texts than listen to them, while more-proficient learners generally utilize a wider range of cues (caption, speaker and visual), although various factors may mediate these trends. Based on these findings, pedagogical suggestions are made for classroom teachers’ use of captioned videos, along with suggestions for the future research of captioned viewing.
Climate news articles lack basic climate science

Although climate change is arguably the most urgent issue of our time, the general public knows little about climate science. Here, we investigate how often five basic climate facts are conveyed in The New York Times news articles covering climate change from 1980 to 2018. With only one exception, the frequencies with which these facts appear in news articles today are vanishingly small. This suggests that print journalism is a largely untapped resource for educating the public on basic climate facts.
Типы межфирменных связей и их сравнительная экономическая эффективность: исследование отрасли российского ритейла

Based on economic-sociological, marketing, and strategic management literature, we combine two classifications of inter-firm relations (horizontal and vertical) and propose the original typology of four ideal types of inter-firm exchange. The quantitative prevalence and the comparative economic efficiency of each ideal type are estimated using indicators of sales dynamics, changes in commodity range and competitive positions. The empirical analysis is based on data from a standardized survey of 684 corporate managers (of retailer and supplier firms) operating in Russia in the food and non-food markets conducted by the HSE in 2016. The analysis revealed high prevalence of building intensive inter-firm relations in the supply chain and low prevalence of network connections with competitors. Additionally, the combination of horizontal relationships with competitors and building vertical relationships in accordance with the concept of relationship marketing is associated with the highest rates of economic efficiency.

Assessment of cultural beliefs and practices during the postnatal period in an urban field practice area of SRMC, Nandyal, Kurnool, Andhra Pradesh

Background: The postpartum period continues to be an important part of the tradition and culture among Indian women. But frequently the health of the postnatal women is neglected. So, the present study aimed to explore the beliefs and practices in the postpartum period regarding diet, rest, hygiene, confinement and assess association between cultural practices and socio demographic characteristics.Methods: A cross‐sectional descriptive study was conducted in the field practice area of urban SRMC Nandyal. The participants were women who had given births in the past three months. The data was collected using a pre‐tested semi‐structured questionnaire.Results: Among the 140 women, over 75% of women had increased their diet intake postpartum. Vegetables such as brinjal and fruits like papaya were avoided by 58.5% and 63.6% women respectively. Among the mothers 18.3% consumed less than 500 ml of water every day and 22% did not drink milk at all. Household work was avoided by 67% of the women while 79.6% avoided going outdoors. Many women didn’t maintain personal hygiene. Many women took home remedies for faster recuperation. These practices were influenced by the socioeconomic status and the woman’s educational status.Conclusions: Traditional postpartum practices are still popular among women in rural and slum areas in Andhra Pradesh. It is critical to identify the harmful practices and reinforce the positive healthy practices to make postpartum period a healthy and joyful period for the mother.

An Examination of Pre-Service Teachers' Technological Pedagogical Content Knowledge and Beliefs Using Computer Technology in Mathematics Instruction.

The aim of this study was to examine the pre-service mathematics teachers’ technological pedagogical content knowledge and beliefs using computer technology in mathematics instruction, as well as the effects of teacher training programs on these beliefs and knowledge. Participants included 199 pre-service elementary mathematics teachers. Of these, one hundred-eighteen were freshman and eighty-one were senior. Two instruments (Technological Pedagogical Content Knowledge (TPACK) instrument and Belief Scale towards Using Computer Technology in Mathematics Instruction) were used to determine pre-service teachers’ TPACK and beliefs about using computer technology in their instruction. To evaluate pre-service teachers’ TPACK and beliefs, both descriptive and inferential statistics were used. The data showed that the teacher education program has a positive effect on pre-service teachers’ TPACK for mathematics teaching and beliefs using computer technology in mathematics instruction. In addition, there was a positive correlation between pre-service teachers’ belief scores and TPACK scores. So, it can be said that the beliefs using computer technology into instruction is a significant predictor for TPACK.
A New Improved Circular Skip List with Priority Search

Skip list is a data structure with an ordered sequence of elements. It consists of layer of linked list. They consist of a layered structure and all nodes are in the bottom layer. These nodes are reduced to half towards upper layers and thus a pyramid-like structure is formed, which facilitates search, insertion and removal operations. A circular linked list is a type of linked list in which the last node of the list points back to the first node. In this paper we proposed a new data structure improved circular skip list (ICSL). ICSL is created with the help of circular linked list and skip list data structures. In circular linked list, operations are performed on a single round robin list. However, our new data structure consists of circular link lists formed in layers which are linked in a conical way with improved priority search feature. Time complexity of search, insertion and deletion equals to O (log N) in an N-element improved circular skip list data structure. Improved circular skip list data structure is employed more effectively (O(log N)) in circumstances where circular linked lists (O(N)) are used with improved priority searching technique.
On the Interplay Between Consumer Dispositions and Perceived Brand Globalness: Alternative Theoretical Perspectives and Empirical Assessment

Although prior research is congested with constructs intended to capture consumers’ dispositions toward globalization and global/local products, their effects appear to replicate with difficulty, and little is known about the underlying theoretical mechanisms. This investigation revisits the relationship between prominent consumer dispositions (consumer ethnocentrism, cosmopolitanism, global/local identity, globalization attitude) and perceived brand globalness as determinants of consumer responses to global brands. Drawing on selective perception and social identity theories, the authors consider several theory-based model specifications that reflect alternative mechanisms through which key consumer dispositions relate to brand globalness and affect important brand-related outcomes. By employing a flexible model that simultaneously accounts for moderating, mediating, conditional, and direct effects, we empirically test these rival model specifications. A meta-analysis of 264 effect sizes obtained from 13 studies with 23 unique data sets and a total sample of 1,410 consumers raises concerns regarding the (potentially overstated) utility of consumer dispositions for explaining consumer responses to global brands. It also reveals a need for further conceptual contemplation of their function in international consumer research and managerial practice.
Navigating choices to a professional career: the role of subject choice in widening access to universities and the professions

This thesis examines the role of subject choice in widening access to elite universities and to an elite professional financial services firm. The analysis takes place at three transition points in the educational trajectory of young people: at 16+, 18+ and at graduation from university. It provides new evidence about these transitions in three ways. First, using a taxonomy of A-levels developed for this thesis, it uses administrative population data for three cohorts of English students to examine the relationship between social background and A-level subject choices categorised according to their published efficacy for university entry. Less privileged young people are less likely to take A-levels universities say they prefer, but the considerable observed gap is largely accounted for by prior attainment and choices of subjects and qualification types at 14-16. Prior attainment is also of primary importance at the second point of transition, at 18+, but analysis using linked national school and university data suggests that A-level subject choices do make a difference to ranking of university attended, over and above attainment. Finally, the importance of prestige of university and the subject of study in the third transition, to graduate employment in an elite profession is considered, using newly available applications and admissions data from a large professional financial services firm. Again, the large raw gap in success rates by university type is almost entirely accounted for by prior attainment, although degree course subject plays a minor role. The direct effect of A-level subject choice is negligible at this transition. The overall thrust of this thesis is that prior attainment and earlier qualifications choices have consequences at each transition, but, over and above attainment, A-level choices can affect high status university entry, and hence, to some extent, gaining a top graduate traineeship.
