Aspect-Based Helpfulness Prediction For Online Product Reviews, Yinfei Yang, Cen Chen, Forrest Sheng Bao

Research Collection School Of Computing and Information Systems

Product reviews greatly influence purchase decisions in online shopping. A common burden of online shopping is that consumers have to search for the right answers through massive reviews, especially on popular products. Hence, estimating and predicting the helpfulness of reviews become important tasks to directly improve shopping experience. In this paper, we propose a new approach to helpfulness prediction by leveraging aspect analysis of reviews. Our hypothesis is that a helpful review will cover many aspects of a product at different emphasis levels. The first step to tackle this problem is to extract proper aspects. Because related products share common …

Distributive Outcomes In Contested Maritime Areas: The Role Of Inside Options In Settling Competing Claims, Áslaug Ásgeirsdóttir, Martin Steinwand

All Faculty Scholarship

Outside options can induce bargaining asymmetries that influence the outcome of international negotiations. This article focuses, however, on the impact of a regime-provided inside option on the willingness to cooperate and the distributive outcomes reached. Using a new data set covering 417 maritime boundaries, that fall under the Law of the Sea framework, this article shows that the ability to find agreement is closely linked to the distributional outcomes that states are able to realize. Different potential gains from cooperation result in bargaining asymmetries that influence both the ability to settle a maritime boundary and the distributive outcome reached when …

A Browser-Based Ide For The Muzecs Platform, Omokolade Hunpatin, Casey O'Hare, Ryan Thomas, Dennis Brylow

Mathematics, Statistics and Computer Science Faculty Research and Publications

We report on a scalable, portable, and secure visual development environment for programming embedded Arduino platforms with Chromebooks in a successful secondary school computer science curriculum. Our web-based environment is part of the larger MUzECS project, an inexpensive replacement module for the Exploring Computer Science (ECS) course being widely deployed in United States high schools. Students use MUzECS to gain a deeper understanding of computing, through a set of blocks which provide appropriate abstractions for working with low-level hardware.

MUzECS improves upon the existing curriculum module by reducing the hardware cost by an order of magnitude, while still preserving the …

It Is Time For Washington State To Take A Stand Against Holmes's Bad Man: The Value Of Punitive Damages In Deterring Big Business And International Tortfeasors, Jackson Pahlke

University of Michigan Journal of Law Reform

In Washington State, tortfeasors get a break when they commit intentional torts. Instead of receiving more punishment for their planned bad act, intentional tortfeasors are punished as if they committed a mere accident. The trend does not stop in Washington State—nationwide, punitive damage legislation inadequately deters intentional wrongdoers through caps and outright bans on punitive damages. Despite Washington State’s one hundred and twenty-five year ban on punitive damages, it is in a unique and powerful position to change the way courts across the country deal with intentional tortfeasors. Since Washington has never had a comprehensive punitive damages framework, and has …

The Academic Impact Of Extracurricular Activities On Middle School Students, Lauren Jansen

Dissertations

This research study examined the academic impact of extracurricular activities on middle school students. This study investigated a possible relationship between the amount of hours that students spent participating in extracurricular activities and their academic achievement, as well as the amount of hours that students spent participating in in-school extracurricular activities and their academic achievement. This study used a combination of quantitative and qualitative data to reach its results. The quantitative data ultimately did not show a statistically significant correlation between the hours that students spent in extracurricular activities in general or in in-school activities and academic achievement. However, there …

Patent Silences, Dan L. Burk

Vanderbilt Law Review

A great deal has been said in recent years about patent disclosure. But to say that there is a disclosure function in the patent system implies that there is non-disclosure functioning in the patent system as well. For some information to be disclosed in a patent, other information must go undisclosed; for some things to be included, other things must be excluded. In this article I review the surprising number of doctrines that allow and encourage patent applicants to remain silent about aspects of their inventions. I find that some silences in patents are inadvertent, while some are deliberate; some …

Coupling Of Coronal And Heliospheric Magnetohydrodynamic Models: Solution Comparisons And Verification, V. G. Merkin, R. Lionello, J. G. Lyon, J. Linker, T. Török, C. Downs

Dartmouth Scholarship

Two well-established magnetohydrodynamic (MHD) codes are coupled to model the solar corona and the inner heliosphere. The corona is simulated using the MHD algorithm outside a sphere (MAS) model. The Lyon–Fedder–Mobarry (LFM) model is used in the heliosphere. The interface between the models is placed in a spherical shell above the critical point and allows both models to work in either a rotating or an inertial frame. Numerical tests are presented examining the coupled model solutions from 20 to 50 solar radii. The heliospheric simulations are run with both LFM and the MAS extension into the heliosphere, and use the …

Hidden Markov Chain Analysis: Impact Of Misclassification On Effect Of Covariates In Disease Progression And Regression, Haritha Polisetti

USF Tampa Graduate Theses and Dissertations

Most of the chronic diseases have a well-known natural staging system through which the disease progression is interpreted. It is well established that the transition rates from one stage of disease to other stage can be modeled by multi state Markov models. But, it is also well known that the screening systems used to diagnose disease states may subject to error some times. In this study, a simulation study is conducted to illustrate the importance of addressing for misclassification in multi-state Markov models by evaluating and comparing the estimates for the disease progression Markov model with misclassification opposed to disease …

2016 Columbia River Flowering Rush Survey, Rich Miller, Mark D. Sytsma

Center for Lakes and Reservoirs Publications and Presentations

Flowering rush (Butomus umbellatus L.) early detection surveys were conducted in Lake Umatilla during the summer of 2016. Flowering rush is a Class A Noxious Weed in Washington State due to its aggressive nature, ecological and economic impacts, and limited distribution. Dense stands can outcompete native riparian plants, interfere with boating and fishing, and impede irrigation flows. Flowering rush has been reported in eight Washington counties (WSDA 2016) including a large infestation detected during 2008 in the Yakima River, Benton County. Several pioneering populations have since been detected further downstream in Lake Wallula and Lake Umatilla on the Columbia River …

Hard-Wall And Non-Uniform Lattice Monte Carlo Approaches To One-Dimensional Fermi Gases In A Harmonic Trap, Casey E. Berger, Joaquín E. Drut, William J. Porter

Physics: Faculty Publications

We present in detail two variants of the lattice Monte Carlo method aimed at tackling systems in external trapping potentials: a uniform-lattice approach with hard-wall boundary conditions, and a non-uniform Gauss–Hermite lattice approach. Using those two methods, we compute the ground-state energy and spatial density profile for systems of N=4–8 harmonically trapped fermions in one dimension. From the favorable comparison of both energies and density profiles (particularly in regions of low density), we conclude that the trapping potential is properly resolved by the hard-wall basis. Our work paves the way to higher dimensions and finite temperature analyses, as calculations with …

Guidelines To Avoid Typical Difficulties According To The Rubric For Experimental Design (Red), Annwesa Dasgupta, Nancy Pelaez

PIBERG Publications

Experimental design is an important component of undergraduate biology education as it generates knowledge of biology. Despite its importance, there is limited information about what students actually learn from designing experiments. Dasgupta et al (2014) reported on the development and validation of a Rubric for Experimental Design (RED), informed by a literature review and empirical analysis of thousands of undergraduate biology students’ responses to three published assessments. The RED is a useful probe for five major areas of experimental design abilities: the variable properties of an experimental subject; the manipulated variables; measurement of outcomes; accounting for variability; and the scope …

Summarization Of Egocentric Videos: A Comprehensive Survey, Ana Garcia Del Molino, Cheston Tan, Joo-Hwee Lim, Ah-Hwee Tan

Research Collection School Of Computing and Information Systems

The introduction of wearable video cameras (e.g., GoPro) in the consumer market has promoted video life-logging, motivating users to generate large amounts of video data. This increasing flow of first-person video has led to a growing need for automatic video summarization adapted to the characteristics and applications of egocentric video. With this paper, we provide the first comprehensive survey of the techniques used specifically to summarize egocentric videos. We present a framework for first-person view summarization and compare the segmentation methods and selection algorithms used by the related work in the literature. Next, we describe the existing egocentric video datasets …

Vireo @ Trecvid 2016: Multimedia Event Detection, Ad-Hoc Video Search, Video-To-Text Description, Hao Zhang, Yi-Jie Lu, Chong-Wah Ngo

Research Collection School Of Computing and Information Systems

Multimedia events such as “birthday party” usually involve the complex interaction between humans and objects. Unlike actions and sports, these events rarely contain unique motion patterns to be vividly explored for recognition. To encode rich objects in the events, a common practice is to tag an individual video frame with object labels, represented as a vector signifying probabilities of object appearances. These vectors are then pooled across frames to obtain a video-level representation. The current practices suffer from two deficiencies due to the direct employment of deep convolutional neural network (DCNN) and standard feature pooling techniques. First, the use of …

Static Loop Analysis And Its Applications, Xiaofei Xie

Research Collection School Of Computing and Information Systems

Loops are challenging structures in program analysis, and an effective loop analysis is crucial in the applications, such as symbolic execution and program verification. In the research, we will first perform a deep analysis and propose a classification according to the complexity of the loops. Then try to propose techniques for analyzing and summarizing different loops. At last, we apply the techniques in multiple applications.

Accident Rates, Phase Of Operations, And Injury Severity For Solo Students In Pursuit Of Private Pilot Certification (1994–2013), Douglas Boyd, Peter Dittmer

Publications

Flight training accidents constitute 14% of general aviation accidents. Herein we determined the rates, injury severity, and phase of flight for primary student solo accidents/incidents (mishaps) in Cessna 172 aircraft. Mishaps over the period spanning 1994–2013 were identified from the NTSB database. Student population data were from the FAA. Statistics employed proportion tests, Poisson distribution, and Mann-Whitney tests. Across the study period, 598 mishaps were identified. While the mishap rate increased nearly two-fold between 1994/1997 and 2002/ 2005, a 35% decline was evident thereafter. Nevertheless, no statistical difference in mishap rates was evident between the initial and current periods. Over …

Service Adaptation With Probabilistic Partial Models, Manman Chen, Tian Huat Tan, Jun Sun, Jingyi Wang, Yang Liu, Jing Sun, Jin Song Dong

Research Collection School Of Computing and Information Systems

Web service composition makes use of existing Web services to build complex business processes. Non-functional requirements are crucial for the Web service composition. In order to satisfy non-functional requirements when composing a Web service, one needs to rely on the estimated quality of the component services. However, estimation is seldom accurate especially in the dynamic environment. Hence, we propose a framework, ADFlow, to monitor and adapt the workflow of the Web service composition when necessary to maximize its ability to satisfy the non-functional requirements automatically. To reduce the monitoring overhead, ADFlow relies on asynchronous monitoring. ADFlow has been implemented and …

Scaling Bdd-Based Timed Verification With Simulation Reduction, Truong Khanh Nguyen, Tian Huat Tan, Jun Sun, Jiaying Li, Yang Liu, Manman Chen, Jin Song Dong

Research Collection School Of Computing and Information Systems

Digitization is a technique that has been widely used in real-time model checking. With the assumption of digital clocks, symbolic model checking techniques (like those based on BDDs) can be applied for real-time systems. The problem of model checking real-time systems based on digitization is that the number of tick transitions increases rapidly with the increment of clock upper bounds. In this paper, we propose to improve BDD-based verification for real-time systems using simulation reduction. We show that simulation reduction allows us to verify timed automata with large clock upper bounds and to converge faster to the fixpoint. The presented …

Designing Minimal Effective Normative Systems With The Help Of Lightweight Formal Methods, Jianye Hao, Eunsuk Kang, Jun Sun, Daniel Jackson

Research Collection School Of Computing and Information Systems

Normative systems are an important approach to achieving effective coordination among (often an arbitrary number of) agents in multiagent systems. A normative system should be effective in ensuring the satisfaction of a desirable system property, and minimal (i.e., not containing norms that unnecessarily over-constrain the behaviors of agents). Designing or even automatically synthesizing minimal effective normative systems is highly non-trivial. Previous attempts on synthesizing such systems through simulations often fail to generate normative systems which are both minimal and effective. In this work, we propose a framework that facilitates designing of minimal effective normative systems using lightweight formal methods. Given …

From The Bachelor's To The Bar: Using College Completion Data To Assess The Law School Pipeline, Accesslex Institute

AccessLex Institute Research

The story of declining law school applications is well known among the legal education community. Over 100,000 individuals applied to law school for admission in fall 2004, but demand for legal education has since declined — only 54,000 applicants sought admission in fall 2015. Accesslex Institute examined college completion data to determine whether undergraduate interest in fields most popular among law school applicants has also waned in recent years. In particular, this research brief summarizes bachelor’s degree completion in the top 10 law school feeder majors over the last 10 years, and compares degree production in these fields to those …

How To Quantify The Temporal Storage Effect Using Simulations Instead Of Math, Stephen P. Ellner, Robin E. Snyder, Peter B. Adler

Wildland Resources Faculty Publications

The storage effect, originally a theoretical hypothesis to explain how ecologically similar species could coexist by responding differently to environmental variability (Chesson & Warner, 1981; Shmida & Ellner, 1984), has developed into a core concept in community ecology (Mittelbach 2012)with empirical support from communities of prairie grasses (Adler et al., 2006), desert annual plants (Pake & Venable, 1995; Angert et al., 2009), tropical trees (Usinowicz et al., 2012) and zooplankton(Caceres, 1997). An essential step in this maturation was mathematical analysis (Chesson, 1994, 2000a) that identified the conditions required for the storage effect to help stabilize coexistence of competitors. For the …

Pegxit Pressure: Evidence From The Classical Gold Standard, Kris James Mitchener, Gonçalo Pina

Economics

We develop a simple model that highlights the costs and benefits of fixed exchange rates as they relate to trade, and show that negative export-price shocks reduce fiscal revenue and increase the likelihood of an expected currency devaluation. Using a new high-frequency data set on commodity-price movements from the classical gold standard era, we then show that the model’s main prediction holds even for the canonical example of hard pegs. We identify a negative causal relationship between export-price shocks and currency-risk premia in emerging market economies, indicating that negative export-price shocks increased the probability that countries abandoned their pegs.

Approximate Time To Steady-State Resting Energy Expenditure Using Indirect Calorimetry In Young, Healthy Adults, Collin J. Popp, Jocelyn J. Tisch, Kenan E. Sakarcan, William C. Bridges, Elliot D. Jesch

Publications

Indirect calorimetry (IC) measurements to estimate resting energy expenditure (REE) necessitate a stable measurement period or steady state (SS). There is limited evidence when assessing the time to reach SS in young, healthy adults. The aims of this prospective study are to determine the approximate time to necessary reach SS using open-circuit IC and to establish the appropriate duration of SS needed to estimate REE. One hundred young, healthy participants (54 males and 46 females; age = 20.6 ± 2.1 years; body weight = 73.6 ± 16.3 kg; height 172.5 ± 9.3 cm; BMI = 24.5 ± 3.8 kg/m^{2 …}

The Voices Of Educators: An Interview Study Of The Implementation Process Of The English/Language Arts Common Core State Standards Initiative, Efren Ponce

LMU Theses and Dissertations

Historically, disenfranchised students in the American education system have been promised opportunity through successful participation in the school system. These promises are voiced in legislation like the Elementary and Secondary Education Act of 1965 and by executive actions like President Obama’s Race to the Top Initiative. Evidenced by the continuing education gap, the promises of success through education continue to evade many American children across the nation, especially students who are most in need of the support promised in these quixotic visions of opportunity.

This is a qualitative interview study that aimed to gather the voices of educators involved in …
