All Aboard, All Attuned And All Involved: Fostering Learner Engagement And Teamwork With Clickers In An Introductory Computer Science Course At Winthrop University, Patrick Guilbaud, Michael Whitney

Winthrop Conference on Teaching and Learning

Modern education technology tools and learning systems provide the means for faculty to develop courses that offer connected and engaging learning opportunities. However, many courses, particularly those in the sciences and engineering disciplines, are not often designed to encourage collaboration, cooperation and teamwork.

Given the presence of a global and interconnected economy, it is critical for students to interact with classmates who hold diverse perspectives, experiences and opinions. Moreover, research shows that students who have had the opportunity to participate in learning activities with heterogeneous teams --early in their college life-- are more likely to develop lasting relationships with classmates ...


Online Multi-Modal Distance Metric Learning With Application To Image Retrieval, Pengcheng WU, Steven C. H. HOI, Peilin ZHAO, Chunyan MIAO, Zhi-Yong LIU 2016 Singapore Management University

Online Multi-Modal Distance Metric Learning With Application To Image Retrieval, Pengcheng Wu, Steven C. H. Hoi, Peilin Zhao, Chunyan Miao, Zhi-Yong Liu

Research Collection School Of Information Systems

Distance metric learning (DML) is an important technique to improve similarity search in content-based image retrieval. Despite being studied extensively, most existing DML approaches typically adopt a single-modal learning framework that learns the distance metric on either a single feature type or a combined feature space where multiple types of features are simply concatenated. Such single-modal DML methods suffer from some critical limitations: (i) some type of features may significantly dominate the others in the DML task due to diverse feature representations; and (ii) learning a distance metric on the combined high-dimensional feature space can be extremely time-consuming using the ...


The Future Of Artificial Intelligence- Do We Have Anything To Fear?, Katina Michael 2016

The Future Of Artificial Intelligence- Do We Have Anything To Fear?, Katina Michael

Professor Katina Michael

Katina Michael discusses the future prospects of artificial intelligence with Fiona Willey. She emphasises the word "artificial" and notes that "decision making" and "simulation" by computers will never be perfect. Currently, researchers are working in the burgeoning area of Machine Learning, Deep Learning and Reinforcement Learning. Well-known theorists and academics like Stephen Hawking, Elon Musk, and Nick Bostrom note the potential for dangerous scenarios to play, even the possibility of the 'end' of humanity through AI. Katina notes that superintelligence will likely play out in the Cloud and how to harness that power might see an opportunity to interface with ...


Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William D. Kearns, James L. Fozard, Vilis O. Nams 2016

Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William D. Kearns, James L. Fozard, Vilis O. Nams

William D. Kearns, PhD

Ambulation is defined by duration, distance traversed, number and size of directional changes and the interval separating successive movement episodes; more complex measures of ambulation can be created by aggregating these features. This review article of published findings defines random changes in direction during movement as “movement path tortuosity”, and relates tortuosity to the understanding of cognitive impairments of persons of all ages. Path tortuosity is quantified by subjecting tracking data to fractal analysis, specifically Fractal Dimension (Fractal D), which ranges from a value of 1 when the movement path is perfectly straight to a value of 2 when the ...


Dynamically Testing Graphical User Interfaces, Santo Carino 2016 The University of Western Ontario

Dynamically Testing Graphical User Interfaces, Santo Carino

Electronic Thesis and Dissertation Repository

Software test generation for GUIs is a hard problem. The goal of this thesis is to investigate different methods for dynamically generating tests for GUIs. We introduce the concept of an event-pair graph, which is used to represent and measure test suites, and show how it can be used to generate tests and measure GUI coverage. Before we can begin generating tests, we first want to determine which is better: a small test suite with a few long tests or a large test suite with many short tests. Therefore, we designed and conducted a study to determine which is more ...

Choosing A Repository Platform: Open Source Vs. Hosted Solutions, Hillary Corbett, Jimmy Ghaphery, Lauren Work, Sam Byrd

VCU Libraries Faculty and Staff Publications

Discusses selection of a locally hosted, open-source system (DSpace/Fedora) versus a cloud-hosted, proprietary system (Digital Commons), it is important to note that these examples are merely illustrative. Libraries have a range of choices for repository software that includes open source and proprietary in any number of support environments, and exemplary repositories are flourishing on a variety of systems, both open source and proprietary. This chapter focuses on the differences between proprietary and open-source solutions, but also demonstrates how and why libraries choose a repository system. In writing about this process, we realized that it was important to acknowledge that ...

An Empirical Investigation Of Privacy And Security Concerns On Doctors’ And Nurses’ Behavioral Intentions To Use Rfid In Hospitals, Thomas George Winston

CEC Theses and Dissertations

Radio frequency identification (RFID) technology is a useful technology that has myriad applications in technology, retail, manufacturing, and healthcare settings. Not dependent upon line-of-sight, RFID can scan devices in their proximity and report the information to connected (wired or other wireless) information systems. Once touted as the panacea for home healthcare, RFID devices can add benefit to patients in remote settings. RFID devices have been used to optimize systems in areas such as manufacturing and healthcare to expose inefficiencies in a system or process. Unlike manufacturing, however, RFID in healthcare settings presents security and privacy concerns to the people being ...

Cluster-Based Salient Object Detection Using K-Means Merging And Keypoint Separation With Rectangular Centers, Robert Buck 2016 Utah State University

Cluster-Based Salient Object Detection Using K-Means Merging And Keypoint Separation With Rectangular Centers, Robert Buck

All Graduate Theses and Dissertations

The explosion of internet traffic, advent of social media sites such as Facebook and Twitter, and increased availability of digital cameras has saturated life with images and videos. Never before has it been so important to sift quickly through large amounts of digital information. Salient Object Detection (SOD) is a computer vision topic that finds methods to locate important objects in pictures. SOD has proven to be helpful in numerous applications such as image forgery detection and traffic sign recognition. In this thesis, I outline a novel SOD technique to automatically isolate important objects from the background in images.


How Can We Have A Better Public Transportation System? –An Exploratory Agent Based Model, Boyu Liu 2016 Pomona College

How Can We Have A Better Public Transportation System? –An Exploratory Agent Based Model, Boyu Liu

Pomona Senior Theses

Public transportation plays an integral part in a city's development, but transportation professionals disagree about whether it is feasible to increase the capacity of public transportation systems at a reasonable cost; and if it is, how. This study develops an agent based model that aims to answer this question and provide a framework to compare the effects of improvements in different aspects of the public transportation service. The results of this study show that it is possible to increase ridership enough to compensate for the increased operational cost, but only in certain circumstances. Interesting phenomenon that might have showed ...

Exploring Knowledge Management Models On Information Technology Projects, Alan Richard Foote

Walden Dissertations and Doctoral Studies

One way an organization manages the knowledge of its people is in information technology (IT) projects. Organizations develop IT projects for many socially responsible reasons, including improved health care services and better community services. IT projects do not always achieve the goals of the organization when the knowledge of the stakeholders is not managed for these objectives. For this study the purpose was to address the use of knowledge management (KM) in project management (PM) to improve the success of IT projects in achieving the organizational goals. The research questions were based on KM including its tools and techniques to ...

Empirical Examination Of User Acceptance Of Enterprise Resource Planning Systems In The United States, Rohan Oldacre

Walden Dissertations and Doctoral Studies

Enterprise resource planning (ERP) systems are complex software packages that support an integrated real-time setting among the various business functions in an entire organization. ERP systems improve productivity, but only to the extent that employees accept and use the systems extensively to perform their duties. The leaders of many organizations have not been able to realize the expected benefits because of a lack of user acceptance. The purpose of this quantitative cross-sectional survey study was to examine the factors that influence user acceptance of ERP systems in the United States. Davis's technology acceptance model was the theoretical foundation used ...


Discrete Mathematics: Chapter 0, Table Of Contents And Preface, Calvin Jongsma 2016 Dordt College

Discrete Mathematics: Chapter 0, Table Of Contents And Preface, Calvin Jongsma

Faculty Work: Comprehensive List

Discrete mathematics, you may be disappointed to discover, is not the sort of stuff you talk about discreetly, in secretive whispers behind closed doors. It can be discussed in public by anyone; it has lots of important everyday connections. The term discrete means separate or disconnected; its opposite is continuous. Discrete mathematics deals with non-continuous quantitative phenomena — activities as mundane as counting objects and as arcane as ana-lyzing the output of a Turing machine. It also includes familiar topics like functions, but it explores their structural algebraic features and examines them with respect to computational complexity; matters connected to continuity ...


Discrete Mathematics: Chapter 6, Functions & Equivalence Relations, Calvin Jongsma 2016 Dordt College

Discrete Mathematics: Chapter 6, Functions & Equivalence Relations, Calvin Jongsma

Faculty Work: Comprehensive List

Modern science and contemporary Western culture are unthinkable without high-level mathematics. Quantitative modes of thinking, mathematical ideas, algorithmic techniques, and symbolic reasoning permeate the way we conceptualize and interact with the world today. After number and its use in computation, the notion of function, usually expressed in terms of a symbolic formula, is probably the most pervasive mathematical idea used in scientific applications. Functions help formulate important causal connections between different types of measures in numerous scientific fields, and they provide a way to compare different algebraic structures in advanced mathematics.

Our interest in functions here will be different than ...
