This study is important because serving English learners, which is the fastest growing population of students, will help close the achievement gap and eliminate gender bias. This study is rooted in the five main hypotheses of Krashen’s theory of second language acquisition (Krashen, 1981, 1982, 2002). To address each of …

Determining The Professional Development Needs Of Florida Integrated Pest Management Extension Agents, Matt Benge, Xavier Martini, Lauren M. Diepenbrock, Hugh A. Smith

Journal of Extension

With agriculture as the second largest economic industry in Florida, the state's Extension agents need subject matter expertise necessary for disseminating the latest in agricultural research information to agricultural producers. Using an exploratory sequential design coupled with a Borich model, we determined the professional development needs of Florida Extension agents working in integrated pest management (IPM). Through our needs assessment, we identified 16 IPM competencies and found that the highest priority relative to needed professional development was for the competency "determining pest thresholds." Extension personnel can use the list generated to assess perceptions of importance and ability level regarding IPM …

"To Have And Enjoy": Seating In Boston's Early Anglican Churches, 1686-1732, Erica Jill Mcavoy

Graduate Masters Theses

In 1686, Massachusetts Bay Colony lost its charter, and the British government exerted more control over Massachusetts, further enveloping the colony into the folds of the Empire. In the same year, the first Anglican church, King’s Chapel, was established in Massachusetts. With these changes, Boston became more involved in Atlantic trade. During the first quarter of the eighteenth century, the people of Boston began to embrace a more English identity that became evident in the products they were buying, the way they were dressing, and how they worshipped. Just as strict Puritan worship rules waned, new, more English-style methods flourished. …

Selective Electrocatalytic Reduction Of Co2 To Co With Iron Nheterocyclic Carbene Complexes And Near-Infrared Absorbance Of Ruthenium(Ii) Photosensitizers Containing A Merocyanine Π-Acceptor, Peter Andrew Catsoulis

Graduate Masters Theses

The catalytic proton-coupled reduction of carbon dioxide into C-1 or “common engine” liquid fuels is currently a highly desirable and green approach to removing anthropogenic CO2 from the atmosphere. The most common approach to this is through electrocatalytic homogeneous reductions utilizing inorganic complexes as catalysts. Current research has moved towards the use of first-row transition metals in catalysts due to their high natural abundances and cheap cost. Iron porphyrin complexes have been vastly studied due to their high product selectivity and turnover frequencies. However, these complexes exhibit short lived activity because of competing reactions in their catalytic cycles, rendering them …

Backplane System Design Considerations For Micro Led Displays, Kush Benara

Theses

Display technologies have evolved from the bulky Cathode Ray Tube based displays to the latest lightweight and low power micro-Led (uLED) based flat panel displays. A display system consists of a device technology that either manipulates the incoming light or emits its own light and a controller circuit to control the behavior of these devices. This system makes up the backplane of a display technology. uLEDs due to their small size provide higher resolution and better contrast than all the previous display technologies like the LCDs and the OLEDs. Backplane system design considerations for a uLED flat panel display is …

"Through A Forest Wilderness:” Native American Environmental Management At Yosemite And Contested Conservation Values In America’S National Parks, Rochelle Bloom, Douglas Deur

Anthropology Faculty Publications and Presentations

Chapter 9. The philosophies and views of nature prevalent in the 19th century West shaped the early National Park Service, and continue to influence park policy today. Park-builders incorrectly viewed early parks as untouched “wilderness,” even as Native peoples continued to occupy, revere, and actively manage lands and resources on these lands. This misapprehension fostered the creation and enforcement of park regulations meant to protect wild spaces, resulting in the displacement of both Native peoples and the culturally significant habitats that they had helped sustain for millennia. Among these regulations, federally imposed restrictions on burning and other traditional plant community …

Cortical Iron Disrupts Functional Connectivity Networks Supporting Working Memory Performance In Older Adults, Valentinos Zachariou, Christopher E. Bauer, Elayna R. Seago, Flavius D. Raslau, David K. Powell, Brian T. Gold

Neuroscience Faculty Publications

Excessive brain iron negatively affects working memory and related processes but the impact of cortical iron on task-relevant, cortical brain networks is unknown. We hypothesized that high cortical iron concentration may disrupt functional circuitry within cortical networks supporting working memory performance. Fifty-five healthy older adults completed an N-Back working memory paradigm while functional magnetic resonance imaging (fMRI) was performed. Participants also underwent quantitative susceptibility mapping (QSM) imaging for assessment of non-heme brain iron concentration. Additionally, pseudo continuous arterial spin labeling scans were obtained to control for potential contributions of cerebral blood volume and structural brain images were used to control …

Teacher Perceptions Of Collegial Collaboration In An Academy Structure., Kristy Marie Field

Electronic Theses and Dissertations

Collaboration in is an often researched, many-named concept with a definition which has historically been unclear. What one calls collegiality another may call teacher teaming and yet another may refer to as professional networking. Scholars agree effective teacher collaboration can lead to higher student achievement, teacher efficacy, and teacher retention. However, as elusive as an agreed-upon definition may be an agreed-upon structure that fosters an effective version of this collaboration. When Ford began the Ford Next Generation Learning initiative, they embarked on the path to developing a school model that focused on school and community partnerships to support long-term, transformational …

Micro-Credentialing: Establishing A Wyoming Framework, Ignacia Goicolea

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Micro-credentialing has become a buzz word in professional development. This new frontier has become a national trend in many areas, from business to industry. The landscape is being defined by private vendors instead of traditional educational enterprises. Vendors are competing to define and control the micro-credentialing market and take micro-credentials beyond its current context of primarily professional development to potentially, in their vision, replace testing, credentialing, and higher education overall. With the promise of expedited completion and competency, substantially lower costs, and ease of access, micro-credentialing is becoming a threat and opportunity as a disruptive and catalytic innovation for higher …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Adding The Third Dimension To Studies Of Parallel Evolution Of Morphology And Function: An Exploration Based On Parapatric Lake-Stream Stickleback, Grant E. Haines, Yoel E. Stuart, Dieta Hanson, Tania Tasneem, Daniel I. Bolnick, Hans Ce Larsson, Andrew P. Hendry

Biology: Faculty Publications and Other Works

Recent methodological advances have led to a rapid expansion of evolutionary studies employing three-dimensional landmark-based geometric morphometrics (GM). GM methods generally enable researchers to capture and compare complex shape phenotypes, and to quantify their relationship to environmental gradients. However, some recent studies have shown that the common, inexpensive, and relatively rapid two-dimensional GM methods can distort important information and produce misleading results because they cannot capture variation in the depth (Z) dimension. We use micro-CT scanned threespine stickleback (Gasterosteus aculeatus Linnaeus, 1758) from six parapatric lake-stream populations on Vancouver Island, British Columbia, to test whether the loss …

Analysis Of The Population Dynamics Of Placida Dendritica And Codium Fragile In The Gulf Of Maine And A Theoretical Discussion Of Invasive Species, Seth Goodnight

Doctoral Dissertations

This dissertation examines several aspects of the biology and ecology of Codium fragile and Placida dendritica in the Gulf of Maine. Scientific interest in nonindigenous species was examined to determine if any patterns were evident that might indicate a change in the status of an invasive species. Interest in C. fragile had waned in recent years, the timing of which coincides with the decreased ecological dominance and apparent naturalization of the alga. Laboratory and field studies were combined to quantify the dynamics in the population of C. fragile and in the recruitment dynamics of P. dendritica. Results of laboratory research …

Characterizing Student Engagement In A Post-Secondary Developmental Mathematics Class And Exploring The Reflexivity Between Social And Sociomathematical Norms, David Fifty

Doctoral Dissertations

Traditionally, post-secondary developmental mathematics courses aspire to equip students with mathematical content knowledge needed to succeed in calculus and subsequent STEM courses. The literature shows that this goal alone is insufficient, as the emphasis on content acquisition often comes at the expense of developing higher-order skills such as argumentation, reasoning, and flexibility in mathematics problem solving (Chiaravalloti, 2009; Partanen & Kaasila, 2014; Star et al., 2015). Redesigning curricula with these additional objectives in mind requires providing students with opportunities to engage with mathematics in ways that may contrast with their past experiences or expectations. It requires changing patterns of classroom …

GRAPE uses events in which a photon scatters between 2 detector elements to measure the polarization of the measured photons. GRAPE consists of 24 collimated polarimeter modules. Each module is made up of 64 rectangular scintillators elements in a grid of 8 × 8 (36 plastic scintillators surrounded by 28 CsI scintillators). GRAPE was flown from Fort Sumner, New Mexico on the morning of September 26th 2014. The experiment was at float altitude for 14.4 …

Magnetoelastic Excitations In Chiral Magnets, Christopher Libby

Doctoral Dissertations

Emergence of quasiparticles is a central concept in condensed matter physics. As an example, in solids, lattice vibrations lead to quantized phonon excitations, which gives rise to many exotic phenomena, including superconductivity. Things become richer in magnetic systems. Collective fluctuations about a magnetic ground state induce the spin wave excitation, whose quantized quasiparticle is dubbed as the magnon. A fundamental question is how phonon and magnon, as two separate degrees of freedom, can be coupled together. More importantly, certain symmetry, such as spatial inversion symmetry, can be broken in novel magnetic textures. It is interesting to explore whether broken symmetry …

Search For An A' Resonance In The Heavy Photon Search 2.3 Gev Data Set, Samantha Katherine Mccarty

Doctoral Dissertations

The Heavy Photon Search (HPS) experiment is based out of the Thomas Jefferson National Accelerator Laboratory in Newport News and is designed to test the potential existence of a new particle, the "heavy photon" or "A'," which has the potential to mediate interactions between dark forces and the Standard Model. HPS is designed to detect the decay of an A' particle into e⁺e⁻ pairs utilizing an electromagnetic calorimeter and a silicon-strip tracking detector. If the theory is correct, the A' could be generated using the Jefferson Lab high-luminosity electron beam incident upon a tungsten target.

In 2016, HPS collected 10.6 …

Paid Family Leave & The Media: A Narrative Policy Framework, Nichole Angelic Horn

Public Affairs Dissertations - Archive

This study seeks to understand how paid family leave laws influence traditional gender roles and stereotypes. The mother homemaker/father breadwinner narrative, a prominent concept within feminist circles, assumes particular gendered roles that include women’s responsibility for unpaid labor within the home. The implications of these gendered roles leave women in an economically disadvantaged position. Given the media’s influence in policy making and function to echo current social values, this study utilizes the Narrative Policy Framework (NPF) to investigate how the media frames these policies, and whether that framing helps to dismantle traditional gender narratives. This study finds that as these …

Evaluating The Performance Of A Multi-Tile Macroalgae Cultivation Structure Using Physical And Numerical Modeling, Zachary John Davonski

Master's Theses and Capstones

A scaled physical-model of a macroalgae cultivation structure was constructed and tested in the UNH wave tank. The physical-model was a 3x3 tile array, consisting of horizontal kelp-growing longlines, node buoys, and mooring lines. The model was scaled by Froude number to a 1:180 length scale. Deployment in the UNH wave tank allowed for evaluation of the design’s performance during wave and current conditions. The model was subjected to waves and simulated currents in order to investigate its response to dynamic loading conditions, as well any anomalous behaviors such as snap loading or component interaction. The motion of the system …

Copyright's Fixation Requirement: Is It Still Needed?, Attamongkol Tantratian

Maurer Theses and Dissertations

While the United States requires fixation for an original work to be entitled to federal copyright protection, many other countries ignore such requirement. The difference could lead to partial copyright protection standards across jurisdictions over certain works that are not fixed. Examples of such works include extemporaneous speeches, lectures, improvisational performances, and contemporary arts that are transitory. Moreover, with today’s rapid development of arts and technologies, creative works can be presented via new media without being fixed in a traditional way. The examples include live streams of lectures and music performances, which have become part of the “new normal.” In …

Who Dreams Of Badges? Gendered Self-Concept And Policing Career Aspirations, Samantha S. Clinkinbeard, Starr J. Solomon, Rachael M. Rief

Criminology and Criminal Justice Faculty Publications

NIJ’s Policing Research Plan (2017-2022) highlights the need to understand factors that attract diverse candidates. We explored whether college students had ever considered policing and found men were significantly more likely than women to contemplate policing careers. Further, we found higher levels of masculinity were associated with greater odds of policing aspirations; the relationship between gender and aspirations was fully mediated by masculine self-concept. Although men typically reported higher masculinity scores, within-gender analyses indicated that masculinity was important for both men and women. Our findings suggest the continued association of masculinity with policing may undercut efforts to recruit a representative …

Politeness In Security Directives: Insights In Browser Compliance For The Human Element, Deanna House, Gabe Giordano

Information Systems and Quantitative Analysis Faculty Publications

The technical protection provided by information security technology is necessary as a frontline defense against threats. However, the human element adds great risk to systems and cannot be ignored. This research explores the human elements related to security communications and intention to comply with security directives. Security communications are more-commonly being sent using richer computer-based channels. While the goal of security communications is the gain compliance, there is still much to learn related to what influences a user to comply. This research explores the effects that (im)politeness has on intention to comply with security directives. The research utilized an experiment …
