(3) Most studies report positive learning outcomes; (4) Mobile phones were the mobile device used …

Understanding Angle And Angle Measure: A Design-Based Research Study Using Context Aware Ubiquitous Learning, Helen Crompton

Teaching & Learning Faculty Publications

Mobile technologies are quickly becoming tools found in the educational environment. The researchers in this study use a form of mobile learning to support students in learning about angle concepts. Design-based research is used in this study to develop an empirically-substantiated local instruction theory about students' develop of angle and angle measure. This local instruction theory involves real-world connections and mobile technologies through a sub category of mobile learning called context-aware ubiquitous learning. Through a process of anticipation, enactment, evaluation, and revision, the local instruction theory was developed to include a theoretical contribution of how students come to understand angle …

Perceptions Of Pedagogical Affordance Of Smart Mobile Technology, Khitam Shraim, Helen Crompton

Teaching & Learning Faculty Publications

Smart mobile devices are becoming ubiquitous among educators and students in Palestine. Mobile devices can be used to provide learning that is contextualized, personalized and unrestricted by location and time. Although these device capabilities are available, many faculty in higher education are not effectively incorporating this technology into their teaching. This study therefore examined academics’ perceptions of the value of integrating mobile devices into their teaching activities. A questionnaire survey collected data from 56 academic staff of the Palestine Technical University - Kadoorie, eliciting perceptions of the pedagogical affordance of mobile devices and challenges to their use in teaching. The …

An Examination Of An Online Tutoring Program's Impact On Low-Achieving Middle School Students' Mathematics Achievement, Shanan Chappell,, Pamela Arnold, John Nunnery, Melva R. Grant

Teaching & Learning Faculty Publications

The purpose of this mixed methods study was to determine the impact of synchronous online tutoring services on struggling middle school students’ mathematics achievement. The online tutoring was provided as a response to intervention (RTI) Tier 3 support (intensive, individualized intervention) in schools implementing a school-wide mathematics program that addresses Tier 1 (high-quality classroom instruction) and Tier 2 (small group interventions). We employed quasi-experimental, within- and between-group designs to examine impacts for 119 students in two schools to measure the tutoring’s impact on mathematics assessment scores. We also conducted qualitative analyses of student and tutor postsession commentary. The findings suggest …

Nonlinear Analysis And Digital Pre-Distortion Of The Sc-Fdma Signals In Lte Uplink System, Changwen Zhu

Dissertations and Theses

Single-carrier frequency division multiple access (SC-FDMA) has become a popular alternative to orthogonal frequency division multiple access (OFDM) in multi-user communication on LTE uplink systems. This is primarily due to the low peak-to-average power ratio (PAPR) of SC-FDMA compared to that of OFDM. Long-term evolution (LTE) uses SC-FDMA on the uplink to exploit this PAPR advantage to reduce transmit power amplifier (PA) back-off in mobile user terminals. However, the latest generation of communication systems requires high power efficiency and a large quantity of capacity in transmitting mobile data, bringing out some other critical problems: 1) the nonlinearity of Radio Frequency …

A pre-designed, …

Exploring A Toll Auction Mechanism Enabled By Vehicle-To-Infrastructure Technology, Andrew J. Collins, Erika Frydenlund, R. Michael Robinson, Mecit Cetin

VMASC Publications

High-occupancy toll (HOT) lanes—an increasingly popular solution for congested roadway networks—give drivers the option to access express lanes. The cost of entry often varies with demand, although no standard method of optimizing these price points exists. Using the principles of a Vickrey auction that incentivizes true-value bids, this paper proposes a tolling system that uses vehicle-to-infrastructure technology to optimize toll operator revenue with HOT lane usage. In the scenario, a roadway network consists of a HOT lane and a general-purpose lane, each with identical physical properties. Drivers can access the HOT lane at the start of the facility or at …

Challenges For Developing Complex System Governance, Charles B. Keating, Polinpaplinho F. Katina, Joseph M. Bradley, Sila Çetinkaya (Ed.), J. K. Ryan (Ed.)

Engineering Management & Systems Engineering Faculty Publications

This paper examines the challenges and practice implications for Complex System Governance (CSG). CSG is presented as an emerging field focused on the design, execution, and evolution of the higher order (metasystem) functions necessary to provide control, communication, coordination, and integration of a complex system. This paper is focused on three primary objectives. First, we introduce the complex system problem domain that the CSG field is being designed to address. The pervasiveness of this problem domain is demonstrated by a short examination of the water utilities sector. Second, we expound the nature of CSG and an emerging reference model …

Engineering Management & Systems Engineering Faculty Publications

Climate change concerns have confronted energy policy makers by unprecedented challenges in the 21st century. Revolution of renewable energy technologies, as well as more efficient energy systems, has been promising in the context of global warming. However, these technologies are not maturing and chaning. Consequently planning for development of these resources requires dealing with various multidisciplinary research questions such as financial feasibility of renewable energy projects. Nevertheless, there is considerable lack of education programs offering multidisciplinary approach for addressing the current energy challenges. Based on the 21st evolving energy landscape, an interdisciplinary graduate certificate course work was designed at Old …

The Medical Cost Pandemic:Why Limiting Access To Cost-Effective Treatments Hurts The Global Poor, Govind Persad

Publications

Medical innovation in developed countries like the U.S. leads to an ever-changing medical standard of care. This innovation frequently also brings rising costs. While these costs strain even the sizeable health care budgets of developed countries, imposing them on developing countries would be much more burdensome. Yet a variety of commentators and legal actors, such as the World Health OrganiZation and UNAIDS, have argued that the same standards of care must be provided worldwide, and have enforced mandates to that effect. Interpretations of the human rght to health as a tight to the "highest attainable standard of health" similarly advance …

Warrior Information Network- Tactical Human View Models & Analysis, Holly A. H. Handley, Cansu Kandemir, Elnaz Dario

Engineering Management & Systems Engineering Faculty Publications

The Human View collects and categorizes data to provide information and analyses on the human component of a system. This organization of human system data helps to understand what the impact of the technology on human performance may be. The first phase of this project completed exploratory work on different Human View techniques in the context of the Warrior Information Network - Tactical (WIN-T) system. This included creating a high-level diagram to provide a conceptual realization of a General Purpose User (GPU) interacting with the WIN-T system, creating engineering diagrams using the System Modeling Language (SysML) to render the Human …

Playing Cowboys And Iranians: Selective Colorblindness And The Legal Construction Of White Geographies, John Tehranian

University of Colorado Law Review

This Article examines the selective invocation of colorblindness in legal and political discourse and argues that the trope has served as a powerful vehicle for the creation, perpetuation, and patrolling of white geographiesspaces characterized by an implicit hierarchy privileging white racial identity. After assessing the new rhetoric of race in the Age of Obama, the Article focuses on identifying and deconstructing the modern paradox of colorblindness jurisprudence. On the one hand, the courts have increasingly hewed to a colorblind vision of the Constitution when weighing the permissibility of race-based admissions and hiring programs for traditionally disadvantaged minorities. And, yet, on …

Complicity And Strict Liability: A Logical Inconsistency?, Michael Bohan

University of Colorado Law Review

"[T]o make a complete crime, cognizable by human laws, there must be both a will and an act.., an unwarrantable act without a vicious will is no crime at all. "I The term "vicious will" illustrates the relationship between blameworthiness and punishment; the foundation of all criminal law, and the justification for the doctrine of complicity liability. The Colorado Supreme Court recently granted certiorari review of People v. Childress, a case in which the Court of Appeals held that one cannot be complicit in a strict liability crime. This holding is difficult to reconcile with Colorado's application of the complicity …

The Adventure Of The Shrinking Public Domain, Elizabeth L. Rosenblatt

University of Colorado Law Review

Several scholars have explored the boundaries of intellectual property protection for literary characters. Using as a case study the history of intellectual property treatment of Arthur Conan Doyle's fictional character Sherlock Holmes, this Article builds on that scholarship, with special attention to characters that appear in multiple works over time, and to the influences of formal and informal law on the entry of literary characters into the public domain. While copyright protects works of authorship only for a limited time, copyright holders have sought to slow the entry of characters into the public domain, relying on trademark law, risk aversion, …

Intrastate Preemption In The Shifting Energy Sector, Uma Outka

University of Colorado Law Review

The United States energy sector is in a state of transition, at once moving toward cleaner energy resources, but also expanding the use of fossil fuels with new access to oil and gas plays. Although federalism concerns have dominated the literature, I argue here that the state-local relationship and intrastate preemption are shaping energy policy in important and under-examined ways. The energy transition to date has been marked by growth centered on hydraulic fracturing (fracking) and commercial wind development, both of which are mostly regulated at the state level. Local governments have exerted authority over both forms of energy production, …

A Prospect Theory Of Privacy, Bryan H. Choi

Publications

Privacy law has languished for decades while the other information law doctrines have flourished. This paradox can be explained by the relative weight assigned respectively to moral argument versus economic argument. Privacy law is unique in that it continues to be steered foremost by moral intuition. What qualifies as a "violation" of privacy is predicated largely on the moral reprehensibility of the act in question. By stark contrast, the intellectual property regimes have long since converted to being led primarily by economic considerations, and only secondarily by noneconomic factors.

That distinction is counterproductive and nonsensical. Personal data is an informational …

For Whom The Data Tolls: A Reunified Theory Of Fourth And Fifth Amendment Jurisprudence, Bryan H. Choi

Publications

Data privacy demands a reunified theory of the Fourth and Fifth Amendments. Data technologies allow personal information to be disembodied from physical bodies and “possessed” simultaneously by both first persons and third parties. As a result, the government has been able to use a divide-and-conquer strategy to obtain incriminating evidence alternately from the data intermediary or from the suspect.

Currently, Fourth Amendment doctrine and Fifth Amendment doctrine work at cross-purposes. The privacy community has already sounded the alarm on the “third-party doctrine,” which allows the government to sidestep the Fourth Amendment when demanding evidence from third parties. But few have …
