Transpolyacetylene chains in hydrogenated amorphous carbon films free of nanocrystalline diamond

The microstructure of distributed electron cyclotron resonance plasma-deposited hydrogenated amorphous carbon films (a-C:H) was investigated using electron diffraction, Raman spectroscopy, and Fourier transform infrared spectroscopy. Experimental evidence of the existence of transpolyacetylene (TPA) chains in a-C:H films free of nanocrystalline diamond is presented. The values of the mean bond angles and lengths and first neighbor numbers are consistent with the TPA data. The Raman spectra were fitted using the G and D bands and the bands centered at 1140, 1233, and 1475 cm(-1) assigned to TPA chains modes. The relative intensity of the latter decreases while hydrogen content decreases. A significant sp(2)-CH olefinic mode contribution to the infrared stretching band is observed for the low-density films (similar to1.2 g/cm(3)). TPA chains growth is enhanced when ion current density and energy decrease. (C) 2003 American Institute of Physics. (DOI: 10.1063/1.1538349

Evaluation of United States Federal Oil Spill Policies: Deepwater Horizon vs. Bouchard B120

ABSTRACT RELIHAN, QUINN An Evaluation of United States Federal Oil Spill Regulations: Deepwater Horizon vs. Bouchard B120. Department of Environmental Science, Policy and Engineering, June 2020. Advisor: ILENE KAPLAN The purpose of this study is to compare and contrast the background, impacts and treatment of two major oil spills and investigate the appropriateness of existing environmental policies and any need for new and/or different policies. The study traces the growth of relevant policy development and looks at historic and contemporary policy changes and applies this to the in-depth examination of the Bouchard B120 and the Deepwater Horizon spills. Policy recommendations are made based on conclusions drawn from the examination of the two case studies. It is recommended that a new classification system be implemented so that each company in the oil industry is appropriately and equally monitored. An important conclusion of this study is that successful oil spill policy is one that stresses preventative measures and is well-enforced by the appropriate agenc

Is online retail killing coffee shops? Estimating the winners and losers of online retail using customer transaction microdata

Is online retail a complement or substitute to local offline economies? This paper provides the first evidence that consumers use time saved from online retail to increase their trips for time-intensive services like coffee shops. I use new, detailed data on the daily transactions of millions of anonymized customers. I then estimate a discrete choice model of consumer trip choice, which embeds time use mechanisms and accounts for correlations in trip utility shocks. I show that the model matches key features of observed behaviour that are missed by more standard models, such as the disproportionate increase in trips to nearby coffee shops when consumers switch to online groceries. Model counterfactuals are used to forecast changes in future trip demand and outline strategies, which offline retailers can use to compete against online retail. For consumers, I find that the welfare gains from online grocery platforms go disproportionately to high-income consumers

Local Interactions Between Firms And Consumers

This dissertation studies how the spatial distributions of firms and consumers shape their interactions in local credit markets. For firms, proximity provides information about the preferences and credit quality of local consumers. For consumers, it facilitates gathering information about product availability and the prices at local firms. I explore these dynamics by developing stylized models that illustrate the key dynamics of interest and motivate empirical estimations that I take to data. In particular, this dissertation uses many novel big data assets that provide new insights into the functioning of local credit markets. In the first chapter, I study whether online retail is a complement or substitute to local offline economies by studying how consumers reorganize their trips to grocery stores and coffee shops after they become online grocery shoppers. To do so, I use new, detailed data on the daily online and offline transactions of millions of anonymized customers. My results show that consumer behaviors can create positive complementarities between online retail and some brick-and-mortar stores, creating both winning and losing stores and consumers to online retail. In the second chapter, I study the impact of branch presence on mortgage credit outcomes in the surrounding neighborhood using the density of nearby bank branch networks to instrument for actual branch presence. I find that lenders with branches lend more mortgages to borrowers in the surrounding neighborhood and that those operated by local lenders have the most positive impact for low socioeconomic-status borrowers. However, I show that branches disadvantage competing lenders by lowering the credit-quality of the competing lenders\u27 applicant pool. This adverse selection causes an aggregate negative effect of branch presence on neighborhood mortgage outcomes. In the third chapter, co-authored with Benjamin J. Keys and Jane K. Dokko, we construct a novel county-level dataset to analyze the relationship between rising house prices and non-traditional features of mortgage contracts. We apply a break-point methodology and find that, in many markets, rising use of non-traditional mortgages predates the start of the housing boom and continues to rise thereafter

HEARING IMPAIRED AND LEADERSHIP: STRUGGLES OF INDIVIDUALS WITH HEARING LOSS IN THE WORKPLACE

With the passing of federal legislations such as the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, Americans believe all issues relating to disability have been addressed. While Americans with disabilities gained civil rights under these two federal laws and educational opportunities have expanded, they are still struggling against the stigma of disability. They encounter many barriers as they enter the workplace and navigate toward leadership roles in their organizations. This narrative phenomenological qualitative study seeks to understand the experiences of individuals with hearing loss as they enter and navigate through their careers. Its purpose is to gain knowledge on the barriers encountered in the workplace and to identify opportunities to implement new strategies to open leadership opportunities for individuals with hearing loss. This study provides stories from five professionals who have worked in different field such as academia, law, finance, and tech industry. Data for this study were collected through online interviews with five participants. Key findings arose from the interviews with the participants, identifying three main themes. The first is a hearing-impaired self-image and personal experiences with their hearing loss. The second is their experiences in their organization (through the orientation process, the organization’s policies toward employees, the hierarchy, and opportunities to become leaders). The third theme is their interactions with colleagues and leaders that impact their career opportunities. This study calls for the recognition of the social and economic barriers individuals with hearing loss face and the need for changes in organizational policies to open leadership opportunities for them. iv This dissertation, written under the direction of the candidate’s dissertation committee and approved by the members of the committee, has been presented to and accepted by the Faculty of the School of Education in partial fulfillment of the requirements for the degree of Doctor of Education. The content and research methodologies presented in this work represent the work of the candidate alone

The Role of Modeling in Teacher Education Programs

Teacher education has come under scrutiny in the recent past because teacher educators are recognizing a gap between what they have traditionally taught in their classrooms, and what new teachers are doing in theirs. Somehow the messages about the effective ways to teach have not been getting through. The solution to the problems seems fairly simple. If beginning teachers are to be effective, they must have a model of the various instructional techniques which can be implemented. Teacher educators, then, must model these techniques in their education courses. In this way, the message clearly comes through, that what is modeled in the college classroom is what should be evident in the classrooms in which they teach

Metodes Meahta in Six Old English Poems

This thesis, then, will attempt to show that the achievement of unity was the primary concern of the Old English poets, who aimed to use the power of poetry to teach their people how their hope for immortality might be realized under Christianity. Their concern is evident from their poetic diction and themes that have an origin in common values of mankind, from their demonstration of unity within the poems by deliberately chosen connotative language and by forms which represent a progression of thought, and from their objective presentations in dramatic and imaginative settings. Therefore, the poetry is a fusion cf Christian cr.d pager, elements based en the Christian messege cf hope for irxDrtality, a common hope of all mankind
