The Presence and Possibility of Moral Sensibility in Beginning Pre-Service Teachers

This paper presents research on the moral sensibility of six pre-service teachers in an undergraduate teacher education program. Using their reflective writing across their first two semesters of coursework as well as focus group interviews in their third semester as sources of data, the paper identifies and describes three distinctive types of moral sensibility and examines ways in which moral sensibility interacts with experiences in teacher education. Suggestions for explicitly incorporating the moral in pre-service teacher education are presented

Reclaiming the Moral in the Dispositions Debate

This article addresses the current debates about the definition and assessment of dispositions in teacher education. Competing perspectives on the definitions and assessment of dispositions in teacher education are examined and critiqued, and a renewed commitment to foregrounding the moral nature of teaching is suggested. Recommendations for understanding and assessing the moral in teacher education, including the development of a code of ethics for the profession, are provided

The Acquisition of Visual Records Relating to Native Life in North America

In 1991, the National Archives of Canada made its first deliberate acquisition of art works by an Indian artist, the Kwaguitl David Neel, who had produced a series of serigraphs relating to events concerning native-white relations in Canada. The first work, Life on the 18th Hole (figure 1 ), was inspired by the events at Oka, Quebec, where Mohawk warriors had blockaded a provincial highway and defied first Quebec provincial police and then Canadian federal troops for more than two months in 1990.1 The second work, Just Say No (figure 2), was a commentary on the stand taken by Elijah Harper, a Manitoba Indian and member of Parliament, whose no vote in a crucial provincial legislature debate resulted in the collapse of a national constitutional accord which had been several years in the making. In 1992, two additional Neel prints were acquired: Trial of Tears, a reaction to an adverse judgement in the Supreme Court of British Columbia to a land claim by the G\u27tsaan Witsoa\u27tin, and the more personal Kwagiutl Family Portrait, a portrait of the artist and his family in traditional motif

The Role of the Insulin Receptor in Skeletal Muscle Insulin Resistance: Evaluation of Two Animal Models

The role of the insulin receptor in muscle insulin resistance was studied. Denervation of skeletal muscle resulted in the rapid appearance of a decrease in basal and insulin stimulated glucose transport, glycogen synthesis and a defect in the activation of glycogen synthase which was independent of levels of glycogen in the muscle. The effect was seen in both predominantly red and predominantly white muscle. There was no change in the denervated muscles\u27 sensitivity to epinephrine-mediated decrease in glycogen synthesis or glycogen content, nor was there a major change in the insulin binding capacity of denervated muscles. A technique was developed to investigate the properties of the insulin receptor solubilized from skeletal muscle. Freezing hindlimb muscles with subsequent powdering and homogenization with buffered Triton X-100 produced a fraction with specific insulin binding. Further purification on agarose-bound wheat germ agglutinin yielded insulin receptors with intact insulin binding, as well as insulin stimulatable autophosphorylation and exogenous substrate kinase activity. The autophosphorylation of the insulin receptor β-subunit in intact tissues was also demonstrated. The binding and kinase domains of insulin receptors solubilized from denervated skeletal muscle were identical to that from contralateral controls. No significant changes were seen in the autophosphorylation of the β-subunit in intact, denervated solei. Injection of insulin in the rat and subsequent partial purification of insulin receptors in the presence of phosphatase inhibitors allowed the demonstration of an increased kinase activity towards histone H2b as compared to saline treated rats. The increase was due to an increase in tyrosine phosphorylation attributed to the activation of the insulin receptor kinase. Again, no change in the insulin receptors from denervated muscles was observed. Streptozotocin diabetes resulted in an increase in specific insulin binding but a decrease in insulin-stimulatable autophosphorylation and tyrosine kinase activity. Structural analysis showed no change in the β-subunit but the β-subunit attained a component with a slower migration on electrophoresis. The β-subunit change was shown to be, in part, due to increased sialic acid content of the receptor subunit. The kinetic and structural changes were reversible with insulin treatment of the rat

“Penniless and Unknown”: Temporality of the Milwaukee County Poor Farm Cemetery - A GIS Analysis

This thesis uses GIS modeling techniques of spatial data, archaeological data, and historical documentation to determine patterning of material culture associated with interments at the Milwaukee County Poor Farm Cemetery (MCPFC), an unmarked cemetery located in Wauwatosa, Wisconsin. Archaeological excavations at the MCPFC in 1991-1992 and again in 2013 recovered over 2,400 individuals associated with Milwaukee County’s practice of providing burial for institutional residents, unidentified or unclaimed individuals sent from the Coroner’s Office, the remains of cadaverized individuals, and community poor from 1862 through 1925 (Richards 2016). Previous research identified two distinct material culture classes; grave goods and grave inclusions. These two broad categories support the interpretation of four potential burial classes (Richards 2016:100). While these artifact associations adequately examine the relationship between material culture and respective burial class, it does not necessarily represent a broad temporal patterning of material culture within a spatial context. This thesis utilizes spatial analyses to identify and examine the distribution of temporality in order to provide a more accurate and complete spatial understanding of the history and land use at the MCPFC. Spatial patterns in the distribution of temporally diagnostic material culture such as coins, footwear, jars or containers, and positively identified individuals are used to refine temporally significant burial clusters across the cemetery. The results of this study refine the current assumptions of land use patterns based on coffin handle distributions and confirm the larger spatial patterning of temporality across the cemetery. This thesis also provides a GIS model and external database designed to facilitate future research of the MCPFC

The relationship of instructional supervision and professional learning communities as catalysts for authentic professional growth : a study of one school division

There has been a shift in education as the focus has moved from the centrality of teaching to the importance of learning (Aseltine, Judith, & Rigazio-DiGilio, 2006). The enhancement of educational experiences and learning of students is a goal shared by instructional supervision (Nolan & Hoover, 2004) and professional learning communities (DuFour & DuFour, 2003). As the need for professional development activities, such as instructional supervision and professional learning communities, to support professional growth continues, how these activities are implemented within a school division remains a critical concern. The purpose of the study was to investigate the links between professional learning communities and instructional supervisory practice as catalysts for authentic professional growth. The result of this study suggests that a zone of authentic professional growth occurs when the activities of professional learning communities and instructional supervision as activities of professional development and reflective practice are aligned. In an era of greater accountability in education school divisions have attempted to support their professional staff with limited resources. Connecting activities to support the goals of the school division, such as professional growth and student learning, is one means of maximizing the use of the resources. There has been considerable research into instructional supervision and professional learning communities however little has been done regarding the connection and implications of these professional activities on each other. The research questions of the study focused on gathering the level of agreement of teachers and in-school administrators regarding qualities of effective instructional supervision and successful professional learning communities. An additional research question focused on what were the criteria of successful professional learning communities that related to effective instructional supervisory practice. The study used mixed research methodology to collect information about one school division. A survey was utilized to collect the perceptions of teachers and in-school administrators regarding successful professional learning communities and effective instructional supervision. The data collected from the survey was analyzed by two interpretation panels, one consisting of teachers and the other consisting of in-school administrators. From the analysis provided by the panels and the survey data collected, it was found that from the perceptions of teachers and in-school administrators in one school system, professional learning communities can contain specific qualities that support effective instructional supervision. The combination of these two professional activities can become a catalyst for authentic professional growth for teachers and in-school administrators. The findings of the study highlights the eight preconditions necessary for an environment or zone of authentic professional growth through the use of professional learning communities to support instructional supervision. Implications, based on key findings, of the study include the need to manage time effectively, and to provide sufficient resources to support instructional supervision through professional learning communities. The school system also needs to develop a culture in which there exists a common understanding of instructional supervision and professional learning communities. It was found that ownership and shared leadership are vital to creating an environment which can embrace the collaborative culture necessary for successful professional learning communities and effective instructional supervision

Diffusion-mediated 129 Xe gas depolarization in magnetic field gradients during continuous-flow optical pumping

The production of large volumes of highly polarized noble gases like helium and xenon is vital to applications of magnetic resonance imaging and spectroscopy with hyperpolarized (HP) gas in humans. In the past ten years, (129)Xe has become the gas of choice due to its lower cost, higher availability, relatively high tissue solubility, and wide range of chemical shift values. Though near unity levels of xenon polarization have been achieved in-cell using stopped-flow Spin Exchange Optical Pumping (SEOP), these levels are currently unmatched by continuous-flow SEOP methods. Among the various mechanisms that cause xenon relaxation, such as persistent and transient xenon dimers, wall collisions, and interactions with oxygen, relaxation due to diffusion in magnetic field gradients, caused by rapidly changing magnetic field strength and direction, is often ignored. However, during continuous-flow SEOP production, magnetic field gradients may not have a negligible contribution, especially considering that this methodology requires the combined use of magnets with very different characteristics (low field for spin exchange optical pumping and high field for the reduction of xenon depolarization in the solid state during the freeze out phase) that, when placed together, inevitably create magnetic field gradients along the gas-flow-path. Here, a combination of finite element analysis and Monte Carlo simulations is used to determine the effect of such magnetic field gradients on xenon gas polarization with applications to a specific, continuous-flow hyperpolarization system

Seeing You, Seeing Me: Social Perspective-Taking as Learning

This paper examines the use of social perspective-taking as learning in an education course in an undergraduate teacher education program. Using curriculum documents, student writing, field notes, faculty journals, and focus group interviews, the study identified the foundational/multicultural content understandings and the emotional responses that social perspective-taking activities promoted. Implications of social perspective-taking in teacher education courses and broader programmatic questions about social perspective-taking pedagogy for teaching and learning are addressed

A Study of Women\u27s Compliance-Gaining Behaviors in Violent and Non-Violent Relationships

Recent research by communication scholars has investigated the dynamics of abusive spousal relationships (Chandler, 1986; Infante, Chandler, & Rudd, 1989; Infante, Chandler-Sabourin, Rudd, & Shannon, 1990; Rancer & Niemasz, 1988; Rudd, Burant, & Beatty, 1994; Sabourin, Infante, & Rudd, 1993). Infante and his colleagues have suggested that those involved in violent relationships communicate differently with their partners than those involved in nonviolent relationships. Based on this prior research, it seems important for communication scholars to further investigate the communication behaviors of individuals involved in violent relationships. This current study seeks to advance the family violence research by comparing the types of compliance-gaining strategies that battered and non-battered women report using during their disputes
