    Unitary equivalence to truncated Toeplitz operators

    Full text link
    In this paper we investigate operators unitarily equivalent to truncated Toeplitz operators. We show that this class contains certain sums of tensor products of truncated Toeplitz operators. In particular, it contains arbitrary inflations of truncated Toeplitz operators; this answers a question posed by Cima, Garcia, Ross, and Wogen

    Low Dose CT scanning for Lung Cancer Patrick Strouse Lynn Blazaskie M.S.,R.T.(R)(ARRT) Abstract Computed Tomography (CT) is the imaging of patients in a cross-sectional plane using x-ray. CT is used to diagnose diseases and is producing more efficient ways of this by making radiation dose lower, this leads to Low Dose CT and its abilities in diagnosing lung cancer. The research portrayed in this project provides points across the different aspects of Low Dose Computed Tomography (CT) and its relation to lung cancer to explain the growing new scan of Low Dose CT. Lung cancer is described as a cancer originating in the lungs which the cells grow exponentially causing many mortalities in the world. Lung cancer can be determined by many risk factors such as smoking, radon exposure, family history of lung cancer, and even diet. The symptoms for lung cancer may not be apparent early on, but many researchers find that detecting it early is the best chance for survival. Incorporating evidence shows that Low Dose CT is the best way to detect lung cancer early and to substantially raise the survival rate of this deadly disease, in evidence it shows the statistics of early findings on these scans as compared to others. This research also brings into consideration some of the reasons people may not have access to these scans, this is because of the newer technology and many do not know of it or its effectiveness to save lives. Some future work with these findings should raise the awareness of this scan and educate more individuals.

    Nurse Educators\u27 Perceptions About the Culture of Nursing and Their Role in Bringing Students into that Culture: A Focused Ethnography

    Purpose: The purpose of this study was to discover nurse educators\u27 perceptions about the culture of nursing and how they bring students into that culture. Background: Although the extant literature addresses the process of socialization to the profession, literature exploring socialization as enculturation is scant. Nurse educators\u27 perspectives on the culture of nursing needed further exploration, as their voice on this topic is relatively silent and they provide the first formal enculturation to the profession. Viewing nursing as a professional culture may more effectively enable faculty to clarify and explicate for students the values, behaviors, symbols, and beliefs inherent in the profession. Methodology: This study was a focused ethnography, utilizing Leininger\u27s Four Phases of Data Analysis. Conclusion and Implications: Four main themes emerged from the data. These themes are the culture of nursing is multifaceted, multivalent and at times contradictory; multiple factors both internal and external to the culture influence the culture of nursing; nursing faculty believe that the right conditions facilitate the enculturation of students; navigating the subcultures (academia, service and organizational culture) is challenging for faculty. Theme One reflects faculty participants\u27 views of the diverse characteristics and roles attributed to nurses and the absence of a composite, well-articulated characterization of the culture of nursing other than by value of caring. Theme Two reflects faculty participants\u27 perceptions of the many internal and external factors that influence the culture of nursing. Theme Three captures faculty participants\u27 strong beliefs about what was necessary to bring students into that culture. Theme Four illustrates the many cultural negotiations required daily of faculty participants as they participate in multiple, and at times conflicting subcultures within the culture of nursing. This study has implications for the preparation of nurse educators, curriculum development in nursing education, the education-practice gap, and the role of nurse educators in shaping the culture of nursing
