Visual Complexity Of The Time-Frequency Image Pinpoints The Epileptogenic Zone: An Unsupervised Deep-Learning Tool To Analyze Interictal Intracranial Eeg, Sarvagya Gupta

Graduate Masters Theses

Epilepsy, a prevalent neurological disorder characterized by recurrent seizures, continues to pose significant challenges in diagnosis and treatment, particularly among children. Despite substantial advancements in medical technology and treatment modalities, localization of the part of brain that causes seizures (Epileptogenic Zone) remains a difficult task. Intracranial EEG (iEEG) is often used to estimate the epileptogenic zone (EZ) in children with drugresistant epilepsy (DRE) and target it during surgery. Conventionally, iEEG signals are inspected in the time domain by human experts aiming to locate epileptiform activity.

Visual scrutiny of the iEEG time-frequency (TF) images can be an alternative way to review …

Same Stone, Different Outcomes: Marine Communities On Engineered Vs. Natural Rock Shores, Lucy Anne Dando Lockwood

Graduate Masters Theses

The effort to protect coastal property and infrastructure from storm damage, erosion, and sea level rise has resulted in increased construction of coastal protection structures (CPS) worldwide. Researchers around the globe have found that the marine communities living on CPS differ from those living on natural rock outcroppings in the same area. We conducted a classic disturbance experiment to investigate possible differences in marine organism response and community assembly between natural and human-constructed rocky intertidal habitat along the Massachusetts coast. The one-year study used naturally occurring rock shores and human-made granite seawalls with both wave-exposed and wave-protected areas. Significant differences …

How Data Became Part Of New Orleans’ Dna During The Katrina Recovery, Lamar Gardere, Allison Plyer, Denice Ross

New England Journal of Public Policy

Data intermediaries have a symbiotic relationship with government as the source of most of their information. The open-data movement in government and development of software-as-a-service technologies shaped the data landscape after Katrina. Through relationships and talent transfers with The Data Center, the City of New Orleans went from having its chief technology officer in federal prison and its data systems in shambles to being a nationally recognized leader in open and accountable government. To be effective during disasters, an intermediary should be (1) in place and widely respected before the event, (2) ready to respond immediately after the event and …

Increasing Operator Skills In A Manufacturing Environment, Bobbie Lee Hubbard

Instructional Design Capstones Collection

A plastic-injection molding facility is converting many machines into more automated systems. These complex systems require higher-level skill sets than current operators have been trained in. There is a need to increase the level of competency in most, if not all, of the operators at the Facility, and create a system of levels that engages employees and encourages learning new skills to increase their position and pay.

There is a need for a clear path of compensation based on skills and actions. The Facility is currently not optimizing or maximizing their current portfolio of machines and resources, leaving an unknown …

Unique And Diverse Voices Of African American Women In Engineering At Predominately White Institutions: Unpacking Individual Experiences And Factors Shaping Degree Completion, Ellise M. Davis Lamotte

Graduate Doctoral Dissertations

In 2012, 1% of the African American women who enrolled in an undergraduate engineering program four years prior graduated, amounting to 862 African American women graduating with engineering degrees. This qualitative study, anchored in interpretive phenomenological methodology, utilized undergraduate socialization with an overarching critical race theory lens to examine the manner in which African American women in engineering, such as the 862, make meaning of their experiences at predominately White institutions.

The findings of the study are important because they corroborated existing research findings and more importantly, the findings in this study emphasize the importance of faculty and institutional agent …

Seeing Red: Characterizing Historic Bricks At Sylvester Manor, Long Island, Ny 1652-1735, Martin John Schmidheiny

Graduate Masters Theses

The goal of this project is to develop a basic material characterization of the bricks excavated at the site of Sylvester Manor on Shelter Island, New York. In the early Manor period of 1650-1690, this early Northern provisioning plantation supplied Barbadian sugar operations and pursued mercantile interests independent of state control. Accounting for the range of production defects and material characteristics of the bricks suggests on-site or local manufacture as a regional ceramic industry developed. Qualitative visual analysis and petrographic thin-sections were used to characterize the internal composition, variation and production evidence in the bricks. Interpreting the results of this …

Predicting Hospital Patients' Admission To Reduce Emergency Department Boarding, Mohammadmahdi Moqri

Graduate Masters Theses

Emergency Department (ED) boarding - the inability to transfer emergency patients to inpatient beds- is a key factor contributing to ED overcrowding. This paper presents a novel approach to improving hospital operational efficiency and, therefore, to decreasing ED boarding. Using the historic data of 15,000 patients, admission results and patient information are correlated in order to identify important admission predictor factors. For example, the type of radiology exams prescribed by the ED physician is identified as among the most important predictors of admission. Based on these factors, a real-time prediction model is developed which is able to correctly predict the …

Finishing The Job: A Partnership For Diversity In The Construction Workforce, Susan Moir, Liz Skidmore, Janet Jones, Brian Doherty

Office of Community Partnerships Posters

The Policy Group on Tradeswomen’s Issues (PGTI) is a regional collaboration of construction industry stakeholders working together since 2008 to tackle the persistent failure of policies enacted to open up good paying jobs in the construction trades to women. Our focus on women explicitly supports efforts to increase all forms of diversity in the construction industry. Following the publication of our 2011 founding document, Unfinished Business: Building Equality for Women in the Construction Trades, PGTI has focused on the development and implementation of best practices for a diverse construction workforce in public and non-profit construction.

Emerging Capability Or Continuous Challenge? Relocating Knowledge Work And Managing Process Interfaces, Stephan Manning, Thomas Hutzschenreuter, Alexander Strathmann

Management and Marketing Faculty Publication Series

This study examines interface management as a dynamic organizational capability supporting an increasing global distribution of knowledge work, based on an in-depth case of an automotive supplier. We show how local responses to experiences of task and interface ambiguity following the relocation of R&D processes may lead to a shift of organizational attention from ex-ante process design to continuous process and interface management. Findings suggest that flexible interface manager positions and partnership structures across locations facilitate local experimentation with effective transfer and handling of ambiguous and partially tacit tasks. This enhances the firm’s capacity to distribute an increasing variety of …

Securing Access To Lower-Cost Talent Globally: The Dynamics Of Active Embedding And Field Structuration, Stephan Manning, Joerg Sydow, Arnold Windeler

Management and Marketing Faculty Publication Series

This article examines how multinational corporations (MNCs) shape institutional conditions in emerging economies to secure access to high-skilled, yet lower-cost science and engineering talent. Based on two in-depth case studies of engineering offshoring projects of German automotive suppliers in Romania and China we analyze how MNCs engage in ‘active embedding’ by aligning local institutional conditions with global offshoring strategies and operational needs. MNCs thereby contribute to the structuration of field relations and practices of sourcing knowledge-intensive work from globally dispersed locations.Our findings stress the importance of institutional processes across geographic boundaries that regulate and get shaped by MNC activities.

The Social And Economic Costs Of Employee Misclassification In The Maine Construction Industry, Françoise Carré, Randall Wilson

Center for Social Policy Publications

With this study, a cross disciplinary team of the Center for Construction Policy Research has taken a first and significant step in documenting employee misclassification in the Maine construction industry. This report documents the dimensions of misclassification and its implications for tax collection and worker compensation insurance.

Misclassification occurs when employers treat workers who would otherwise be waged or salaried employees as independent contractors (self employed). Or as one report commissioned by the U.S. Department of Labor put it, misclassification occurs “when workers (who should be) getting W-2 forms for income tax filing instead receive 1099-Miscellaneous Income forms."

Beyond The Big Dig, Robert Turner

New England Journal of Public Policy

For more than a decade, from the day that the decision was made to put Boston’s Central Artery underground, many forward-looking planners and designers have been conjuring up visions of the mile-long street-level corridor that would replace the elevated highway, reshaping the heart of downtown. By the end of 2001, the corridor had acquired a name, the Rose Kennedy Greenway, but work was far more advanced on the traffic tunnel underground than on the open space above. These precious twenty-seven acres had the potential to flower into a magnificent, vibrant urban oasis that would become known the world over. But …

The Mechtech Program: An Education And Training Model For The Next Century, Robert Forrant

New England Journal of Public Policy

The small-firm metalworking industry is routinely characterized by cutthroat competition and fierce privacy. Yet, since the late 1980s, the members of the western Massachusetts chapter of the National Tooling and Machining Association have participated in an education, training, and technology diffusion network characterized by a high degree of interfirm cooperation. Hundreds of workers and managers have take part in group training sessions and seminars. The reconstruction of the skill base is central to the MechTech apprenticeship program through which apprentices spend four years in participating firms, exiting the program as licensed machinists, tool and die makers, or moldmakers. In an …

Dismal Science Meets Dismal Subject: The (Mal)Practice Of Nuclear Power Economics, Charles Komanoff

New England Journal of Public Policy

Electric utilities, reactor designers and builders, and the federal government have badly underestimated the costs of new nuclear power plants over the past fifteen years. Although not all of the increases were readily predictable, particularly those caused by rapid general inflation, nuclear advocates failed to foresee most of the sixfold growth in real costs resulting from new reactors' greater complexity, scope, and regulatory surveillance.

This review recounts the methods used by nuclear power proponents to convince policymakers, the public, and themselves that new nuclear plants would be competitive with other energy sources, long after conclusive contrary evidence was available. It …

Seabrook: A Case Study In Mismanagement, Irvin C. Bupp

New England Journal of Public Policy

The Seabrook nuclear power plant construction project is an unqualified financial disaster. It simultaneously threatens its chief owner, the Public Service Co. of New Hampshire (PSNH) with bankruptcy and the company's electricity customers with huge rate increases. The fifteen-year history of the project is reviewed to identify "what went wrong?"

The review suggests that the basic problem has been mismanagement by both PSNH and by government regulators. A three-year regulatory imbroglio over the environmental effects of the plant's cooling system was extremely costly in the mid-1970s.

By the time this problem was belatedly resolved, the project had begun to outstrip …
