Cross context News Corpus for Protest Events related Knowledge Base Construction
Venue: AKBC
Year: 2020

We describe a gold standard corpus of protest events that comprise of various local and international sources from various countries in English. The corpus contains document, sentence, and token level annotations. This corpus facilitates creating machine learning models that automatically classify news articles and extract protest event related information, constructing databases which enable comparative social and political science studies. For each news source, the annotation starts on random samples of news articles and continues with samples that are drawn using active learning. Each batch of samples was annotated by two social and political scientists, adjudicated by an annotation supervisor, and was improved by identifying annotation errors semi automatically. We found that the corpus has the variety and quality to develop and benchmark text classification and event extraction systems in a cross context setting, which contributes to generalizability and robustness of automated text processing systems. This corpus and the reported results will set the currently lacking common ground in automated protest event collection studies.
Evaluation of students' perceptions of the Socrative application versus a traditional student response system and its impact on classroom engagement.
Venue: Currents in pharmacy teaching learning
Year: 2017

Student response systems (SRSs) or "clickers" are common tools that lecturers can implement into didactic lectures. Socrative is a convenient and free SRS application that can be downloaded on personal handheld devices and used by faculty and students. It is unknown if students prefer using this application and what advantages or disadvantages can be seen with Socrative's use.  To measure student preference of standard SRS methods compared to Socrative as well as the impact of Socrative use on student engagement during delivery of clinical pharmacy instruction  Standard SRS and Socrative incorporated lectures were presented to students during an infectious disease module. Students were given a survey at the end of the semester to determine the primary endpoint of preference for each application. The survey used a Likert scale of 1 5, with 1 strongly disagree and 5= strongly agree. Secondary endpoints included assessing the number of questions asked, participation, and classroom time utilized.  A total of 114 surveys were completed and six were excluded due to discrepancies or reporting bias. A higher mean scoring for classroom facilitation of active learning (4.48 vs. 3.99, p 0.0001) and student reported active participation in class (4.45 vs. 3.60, p 0.0001) was found for Socrative compared to SRSs, respectively.  In comparison with traditional SRS methods, students felt Socrative helped them to more actively participate in class and facilitated a better environment for asking and receiving answers to classroom questions.
Deep learning with multimodal representation for pancancer prognosis prediction
Venue: Bioinform.
Year: 2019

Estimating the future course of patients with cancer lesions is invaluable to physicians; however, current clinical methods fail to effectively use the vast amount of multimodal data that is available for cancer patients. To tackle this problem, we constructed a multimodal neural network based model to predict the survival of patients for 20 different cancer types using clinical data, mRNA expression data, microRNA expression data and histopathology whole slide images (WSIs) We developed an unsupervised encoder to compress these four data modalities into a single feature vector for each patient, handling missing data through a resilient, multimodal dropout method. Encoding methods were tailored to each data type using deep highway networks to extract features from clinical and genomic data, and convolutional neural networks to extract features from WSIs.  We used pancancer data to train these feature encodings and predict single cancer and pancancer overall survival, achieving a C index of 0.78 overall. This work shows that it is possible to build a pancancer model for prognosis that also predicts prognosis in single cancer sites. Furthermore, our model handles multiple data modalities, efficiently analyzes WSIs and represents patient multimodal data flexibly into an unsupervised, informative representation. We thus present a powerful automated tool to accurately determine prognosis, a key step towards personalized treatment for cancer patients.

of Krashen s Input Hypothesis Three Major Arguments
Year: 2016

Second language acquisition (SLA) theories can be grouped into linguistic, psychological and sociocultural theories. Krashen's Monitor Model is seen as an innatist theory within the linguistic group. This paper critically reviews the Input Hypothesis, one of the five hypotheses of Krashen's Monitor Model. It examines three major arguments over the hypothesis, namely, the vagueness of the construct, the simplification of input, and the overclaims that he has made about the hypothesis.

A Novel Many Objective Bacterial Foraging Optimizer Based on Multi engine Cooperation Framework
Venue: ICSI
Year: 2018

In order to efficiently manage the diversity and convergence in many objective optimization, this paper proposes a novel multi engine cooperation bacterial foraging algorithm (MCBFA) to enhance the selection pressure towards Pareto front. The main framework of MCBFA is to handle the convergence and diversity separately by evolving several search engines with different rules. In this algorithm, three engines are respectively endowed with three different evolution principles (i.e. Pareto based, decomposition based and indicator based) and their archives are evolved according to comprehensive learning. In the foraging operations, each bacterium is evolved by reinforcement learning (RL) Specifically, each bacterium adaptively varies its own run length unit and exchange information to dynamically balance exploration and exploitation during the search process. Empirical studies on DTLZ benchmarks show MCBFA exhibits promising performance on complex many objective problems.

Elite Competition, Factionalism and Strongman Governance in a Central China Village
Year: 2017

This study examines the elite political competition in a large agrarian village in Hubei Province. Although known locally as well governed, this village was actually a bifurcated political community with a host of problems. The power struggle between a few members of the village's political elite in the past two decades focused on the office of village Party secretary and produced a polarized politics of factionalism. The town Party committee played a crucial role in selecting the village's Party secretary for economic development with dubious results. This study also examines how and why a strongman Party secretary could hold on to power for 16 years despite an increasing opposition. It reveals the governing dilemma for a village that was hard to govern and the unintended consequences of the Party's recruitment policy for village leaders. Through the elite competition for the past two decades this study aims to capture a total picture of the village politics including its political ecology, agency and dynamics.
Scenario, perspectives and mechanism of arsenic and fluoride Co occurrence in the groundwater: A review.
Venue: Chemosphere
Year: 2020

Arsenic (As) and fluoride (F are the two most conspicuous contaminants, in terms of distribution and menace, in aquifers around the world. While the majority of studies focus on the individual accounts of their hydro geochemistry, the current work is an effort to bring together the past and contemporary works on As and F co occurrence. Co occurrence in the context of As and F is a broad umbrella term and necessarily does not imply a positive correlation between the two contaminants. In arid oxidized aquifers, healthy relationships between As and F is reported owing desorption based release from the positively charged (hydr)oxides of metals like iron (Fe) under alkaline pH. In many instances, multiple pathways of release led to little or no correlation between the two, yet there were high concentrations of both at the same time. The key influencer of the strength of the co occurrence is seasonality, environment, and climatic conditions. Besides, the existing primary ion and dissolved organic matter also affect the release and enrichment of As F in the aquifer system. Anthropogenic forcing in the form of mining, irrigation return flow, extraction, recharge, and agrochemicals remains the most significant contributing factor in the co occurrence. The epidemiological indicate that the interface of these two interacting elements concerning public health is considerably complicated and can be affected by some uncertain factors. The existing explanations of interactions between As F are indecisive, especially their antagonistic interactions that need further investigation. "Multi contamination perspectives of groundwater" is an essential consideration for the overarching question of freshwater sustainability.

Eco Friendly Tamarind Kernel Thickener for Printing of Polyester Using Disperse Dyes
Venue: Fibers and Polymers
Year: 2018

Printing is a form of dyeing in which colors are applied to specified regions instead of the entire fabric. To restrict the coloring matter to the design area, the dyes and other auxiliaries are pasted with a natural or synthetic thickening agent. Finding alternatives to the used thickeners has gained importance lately due to the several limitations associated with toxicity, availability, and cost of the currently used thickeners. Tamarind kernel powder has the potential to be explored as a textile thickener whilst providing economic benefits. Tamarind kernel, derived from the seeds of Tamarindus indica Linn. is a byproduct of the tamarind fruit and pulp industry. It is a low cost, non toxic, biodegradable, cold water soluble thickener. In the present study, an effort has been made to explore the suitability of tamarind kernel thickener for printing of polyester using disperse dyes. On the basis of the qualitative and quantitative analysis, 25 concentration of tamarind kernel powder, steaming temperature of 130 degC for 30 min with carrier was optimized as printing conditions. The samples printed using the given conditions exhibited brighter and sharper lines with uniformity of color. No change in whiteness of the ground and handle of the fabric was seen. Haloing and flushing was observed in samples printed with lower concentrations (5 15 of tamarind kernel thickener. Color value (K/S) of the samples was increased with increase in steaming time and temperature indicating better fixation of dye at high temperatures. All the printed samples irrespective of the varying thickener concentration, steaming time and temperature gave excellent fastness to washing and rubbing.

Progress on next generation gamma ray Cherenkov detectors for the National Ignition Facility.
Venue: The Review of scientific instruments
Year: 2018

Fusion reaction history and ablator areal density measurements for Inertial Confinement Fusion experiments at the National Ignition Facility are currently conducted using the Gamma Reaction History diagnostic (GRH_6m) Future Gas Cherenkov Detectors (GCDs) will ultimately provide ~100x more sensitivity, reduce the effective temporal response from ~100 to ~10 ps, and lower the energy threshold from 2.9 to 1.8 MeV, relative to GRH_6m. The first phase toward next generation GCDs consisted of inserting the existing coaxial GCD 3 detector into a reentrant well which puts it within 4 m of the implosion. Reaction history and ablator gamma measurement results from this Phase I are discussed here. These results demonstrate viability for the follow on Phases of (II) the use of a revolutionary new pulse dilation photomultiplier tube to improve the effective measurement bandwidth by >10x relative to current PMT technology; and (III) the design of a NIF specific "Super" GCD which will be informed by the assessment of the radiation background environment within the well described here.
Edge and confinement effects allow in situ measurement of size and thickness of liquid exfoliated nanosheets.
Venue: Nature communications
Year: 2014

Two dimensional nanomaterials such as MoS2 are of great interest both because of their novel physical properties and their applications potential. Liquid exfoliation, an important production method, is limited by our inability to quickly and easily measure nanosheet size, thickness or concentration. Here we demonstrate a method to simultaneously determine mean values of these properties from an optical extinction spectrum measured on a liquid dispersion of MoS2 nanosheets. The concentration measurement is based on the size independence of the low wavelength extinction coefficient, while the size and thickness measurements rely on the effect of edges and quantum confinement on the optical spectra. The resultant controllability of concentration, size and thickness facilitates the preparation of dispersions with pre determined properties such as high monolayer content, leading to first measurement of A exciton MoS2 luminescence in liquid suspensions. These techniques are general and can be applied to a range of two dimensional materials including WS2, MoSe2 and WSe2.
(Un)seeing dead refugee bodies: mourning memes, spectropolitics, and the haunting of Europe
Year: 2019

This essay addresses the user remediation and performative rematerialization of the 2015 photographs of 3 year old Kurdish Syrian refugee Alan Kurdi, as well as acts of concealing and deferring access to those images following intense public debate. This article shifts the frame of discussion from moral spectatorship to mediated witnessing and networked mourning in the context of contemporary affective publics. To speak of the memeification of Kurdi's corpse image is to underline the way repetition operates as a gesture of both inhabitation and differentiation by users who connect in this way to others and to the issue at hand. The Kurdi images, thus, were not so much observed by a global audience as produced by, and productive of, a massive, dispersed corporeal network. The conceptual figure of spectrality links the mediality and materiality of the dead body image to contemporary necropolitics that dispossesses subjects, producing the 'living death' of the global precariat. If the public sphere is defined by prohibitions on grieving, conflicts regarding who views, mourns, and speaks for which dead bodies, although often ascribed to debased social media mores, tell us more about the political border of human and nonhuman that produces the revenant figure of the refugee haunting inhospitable and neoliberal, but nominally post racial, Europe.
'It's the other assessment that is the key' three Norwegian physical education teachers' engagement (or not) with assessment for learning
Year: 2015

The international agenda for assessment continues to convey a growing interest in assessment for learning (AfL) as a tool to support learning and enhance teaching. Complementing this, the recent literature on assessment in physical education acknowledges the need for physical educators to integrate AfL into their teaching and assessment practice as an important part of the future development of the subject. Appreciating that physical education must be recognized as part of the larger movement culture in society and is a place to learn about movement culture, this study explores how AfL is understood and enacted by physical education teachers and the extent to which such enactment complements or challenges learning movement cultures within physical education. This study shares how three Norwegian physical education teachers used AfL to term what they were practicing with respect to assessment in physical education. We follow the interactions of the selected teachers throughout focus groups, using the empirical data as our 'dialogue partner' in reconstructing and discussing their assessment stories. We conclude that the need of embedding AfL in learning theory may well be one of the strongest challenges to enacting AfL in physical education. We acknowledge that not only are most existing theories of learning defined cognitively, but also that learning connected to physical education and activity is, to a large extent, practical and embodied, and also linked to the powerful discourses of sport and related areas such as health.
