Intraoperative ultrasound (IOUS) is a potentially useful adjunct to the resection of oral tongue cancers (OTC). IOUS images of the tumor-normal tissue interface show different patterns of invasion. In this retrospective series of 29 patients treated for OTC, we evaluated if there was a correlation between IOUS findings of patterns of invasion and final histology and assessed if there was any associated risk of increased incidence of positive or close margins with different patterns of invasion as seen on ultrasound. Although we found no significant correlation between ultrasound patterns of invasion and histological evaluation, we did find that an infiltrative pattern of invasion on IOUS did result in a significant risk of a close margin. Further exploration of these findings in a larger prospective study could provide definitive information on the efficacy of this modality in OTC resections.

Systems of differential equations have been used to model a variety of situations including population dynamics, reactions between several chemicals, and even the outcome of warfare between two nations. These types of systems are well equipped to model both simple and relatively complex situations involving several interacting parties; however, they seem to have never been used to model the interactions between nations engaged in a trade war. This text was primarily developed to showcase the ability of such systems to broadly model the key features of such a trade conflict. We begin by summarizing the main inputs and outputs of several historical trade wars and proceed forward by developing two models utilizing systems of differential equations that incorporate these inputs and outputs into their terms. Following this, we analyze both systems by finding specific solutions to each, by developing a general formula for each system’s equilibria, and by confirming the stability of these equilibria. After the model’s development and analysis, we apply these systems in the controlled environment of a hypothetical trade war. Finally, we conclude with a brief list of limitations that discuss several factors that hinder the accuracy of the proposed models.

Field observations and measurements of wetland plants have traditionally been used to monitor and evaluate wetland condition; however, there has been increasing use of remote sensing applications for rapid evaluations of wetland productivity and change. Combining key aspects of field- and remote sensing-based wetland evaluation methods can provide more efficient or improved biological indices. This exploratory study set out to develop a raster-based Wetland Vegetation Condition Indicator system that used airborne hyperspectral imagery-derived data to estimate plant-community quality (via wetland classification and Coefficient of Conservatism) and vegetation biomass (estimated using the Normalized Difference Vegetation Index). The Wetland Vegetation Condition Indicator system was developed for three Lake Ontario wetland areas and compared to a field-based floristic quality index and a dominant-plant based Floristic quality indexdom. The indicator system serves as a proof-of-concept that capitalized on the spatial and spectral attributes of high-resolution imagery to quantify and characterize the quality and quantity of wetland vegetation. A Pearson correlation analysis showed moderate r values of 0.59 and 0.62 for floristic quality index and floristic quality indexdom, respectively, compared to the indicator method. The differences are potentially due to the spatial resolution of the imagery and the indicator method only accounting for the dominant plants within each assessment unit (pixel), therefore disregarding understory plants or those with low abundance. However, the multi-metric Wetland Vegetation Condition Indicator approach shows promise as an indicator of wetland condition by using remotely sensed data, which could be useful for more efficient landscape-scale assessments of wetland health, resilience, and recovery.

Social work is, by definition, a profession devoted to the pursuit of social justice and the eradication of oppression, inequity, disparities, and other forms of injustice. Social workers are focused on the empowerment of marginalized people and communities and are expected to adhere to clear standards of ethical and competent practice. Additionally, the title of “social worker” is earned through the successful completion of social work education, either on the undergraduate or graduate levels. These social work programs are, in the United States of America, accredited by the Council on Social Work Education (CSWE), which periodically revises and updates its Educational Policy and Accreditation Standards (EPAS)1 and monitors the adherence of each accredited program to these standards. Essentially, CSWE determines the learning of every social worker in the United States.

We present two models to monitor the health of ecosystems by assessing hazard from a persistent organic compound to a top predator species. Our diet model predicts the dietary exposure of American Mink (Neovison vison) to PCB toxic equivalents (TEQ) by combining concentrations in their prey using weighted average proportions consistent with literature-based mink diets. Our bioaccumulation model predicts the dietary exposure of mink to PCB TEQ based on each congener’s total concentration in water (dissolved plus particulate fractions), the octanal/water partition coefcient (log Kow) of the compound, and the trophic levels of prey taxa. Both models predict mink dietary concentrations which can be directly compared with each other and with lowest observable adverse efects concentrations (LOAECs) to assess chronic and acute hazards of PCB TEQ to mink. By our choice of certain parameters in the bioaccumulation model, we forced it to match the diet model within less than 5% for Eighteenmile Creek in western New York State. When the two models were used for a similar creek about 25 km away, the diferences in their predictions were of the same magnitude.

The branding of experience, which works to strengthen consumption practices by tying them into social and group behavior, is an extension of previous efforts that likewise attempt to brand traditionally non-commodified societal institutions including education (Twitchell, 2004), religion (Banet-Weiser, 2012; Twitchell, 2004), and our everyday lives (Moor, 2007). The logic of branding has crept into areas of our lives that previously were not branded – into large institutions like schools and museums and into micro-level everyday experiences and social relationships. This is possible today, in part, due to the rise of networked, social-media-based, smart phone technology that transforms our communication and looking into labor. This communication is increasingly visual; photos, gifs, video, and emoticons, for example, mirror the basic components of a brand.

In the 1980s, the International Joint Commission (IJC) began the process of creating and implementing remedial action plans (RAPs) in 43 areas of concern (AOCs) throughout the Great Lakes Basin of Canada and the United States. An area identified as an AOC violated one or more of 14 “use impairments” listed by the IJC. For example, “fish and wildlife consumption advisories” due to the presence of bioaccumulative chemicals of concern (BCCs) is a use impairment identified for the Rochester, NY Embayment of Lake Ontario AOC.

Ernst Chladni is called the father of acoustics for his work, which includes investigating patterns formed by vibrating plates. Understanding these patterns helps research involving standing waves and other harmonic behaviors, including studies of single electron orbits in atoms. Our experiment vibrates circular plates which result in well-known patterns. Alternatively to traditional experiments that used sand or salt, we use magnetic materials, namely iron filings and nickel powder. We then manipulate the patterns by applying a localized external magnetic field to one of the rings that moves a segment of the magnetic material in that ring to the next inner ring. The results show a significant decrease in magnetic field necessary to move the magnetic material at higher frequencies as well as a significant decrease in the magnetic field required to move the magnetic material as nickel powder is substituted for iron filings while keeping the mass constant.

Guardian involvement is important in student’s academic achievements however that involvement is not consistent across populations. Therefore, this capstone aims to examine the overarching research question: How can teachers foster positive relationships with students that promote parent involvement in the ENL classroom? To answer this question, it is important that teachers and school administration know the struggles families face. Some of these struggles may include language and cultural barriers, education levels of guardians, and the family’s socioeconomic status. The professional development for middle school teachers and school staff will provide strategies and programs that will help increase guardian involvement. As a result of this professional development teachers will have strategies they can implement into their classrooms and in school to increase academic involvement with ELL families. In the future it is important that researchers continue to study the effects that programs such as community programs have on guardian involvement a how it impacts student academics.

This capstone project aims to support the development and use of new strategies that can be used to support English language learners also known as ELLs in the general education classroom. The strategies discovered and explained throughout this paper will be applied to real classrooms and data will be collected to show evidence of successful implementation of the strategies discussed. For the growing population of English language learners attending United States public schools, it is important that we support them academically and in their language development process. Implementing strategies into the classroom is an effective way to support English language learners in the classroom. There are many different strategies that can be used to support students academically and in their language development. The use of Spanish-English cognates is one vocabulary strategy that can be used in the classroom to support language development. Students are taught to look for familiar words as they read in the target language. They are also taught to use other words on the page to help them in determining the meaning of the unknown word, determining if the cognates are in fact true. Another effective strategy is the use of conversations in the classroom. Students can learn language through interaction with classmates. Finding ways to build a language learning and supportive community in the classroom and teaching students how to have meaningful interactions about books leads to support in reading comprehension. Lastly, we will discuss how parent engagement can be included into existing lessons. How parents can teach their children at home and bring a rich learning environment to the home and classroom workspace.
