    PRINCIPALS’ PERCEPTIONS ABOUT THE ELEMENTS OF MENTORING SUPPORT THAT MOST IMPACT THE DEVELOPMENT OF A NEW PRINCIPAL’S LEADERSHIP CAPACITY

    The current study sought to identify and gain a deep understanding of the elements of mentoring support that experienced principals perceive to be most effective in developing beginning principals’ leadership capacity. Q-methodology was utilized to investigate the subjective opinions of public school principals within one school district in North Carolina. The research design of Q-methodology allowed the researcher to capture experienced principals’ beliefs and viewpoints about elements of mentoring support through the collection of both quantitative and qualitative data. Data analysis indicated four statistically significant factors that were named in the study: (1) Trust is the Prerequisite, (2) A Safe Place to Learn, (3) Instructional Leadership in an Era of Accountability, and (4) Relationship is Key. In addition to the statistical analysis, post-sort interviews were conducted for each emergent factor in order to gain further insight about the principals’ perceptions of mentoring support. The findings pointed to gate-keeping mechanisms that lead to better practices for mentoring support. While the content of instructional leadership rose to the top as one of the focus areas for mentoring support, findings notably highlighted the elements of trust and relationship as critical to achieving growth in leadership capacity. The current study’s findings generated implications for policy, further research, and educational practice, which are herein discussed

    Topological kink plasmons on magnetic-domain boundaries.

    Get PDF
    Two-dimensional topological materials bearing time reversal-breaking magnetic fields support protected one-way edge modes. Normally, these edge modes adhere to physical edges where material properties change abruptly. However, even in homogeneous materials, topology still permits a unique form of edge modes - kink modes - residing at the domain boundaries of magnetic fields within the materials. This scenario, despite being predicted in theory, has rarely been demonstrated experimentally. Here, we report our observation of topologically-protected high-frequency kink modes - kink magnetoplasmons (KMPs) - in a GaAs/AlGaAs two-dimensional electron gas (2DEG) system. These KMPs arise at a domain boundary projected from an externally-patterned magnetic field onto a uniform 2DEG. They propagate unidirectionally along the boundary, protected by a difference of gap Chern numbers ([Formula: see text]) in the two domains. They exhibit large tunability under an applied magnetic field or gate voltage, and clear signatures of nonreciprocity even under weak-coupling to evanescent photons

    The alloy undercooling experiment on the Columbia STA 61-C space shuttle mission

    An Alloy Undercooling experiment was performed in an electromagnetic levitator during the Columbia STS 61-C mission in January 1986. One eutectic nickel-tin alloy specimen was partially processed before an equipment failure terminated the experiment. Examination of the specimen showed evidence of undercooling and some unusual microstructural features

    Open Access articleA poor diet during pregnancy has been linked to long-term health outcomes for the baby, such as an increased risk of diseases of the heart and kidney. We show in an experimental model that recreates a poor diet during pregnancy, i.e. a diet low in protein with adequate energy, that kidney development in the baby is affected in such a way as to reduce the potential for new blood vessels to form. This results in a greater number of important, functional kidney cells spontaneously dying. Later in life, these effects in the kidney manifest as permanently reduced kidney function, especially if the baby subsequently becomes overweight as an adult. The research reinforces advice to pregnant mothers about the importance of eating a nutritionally balanced diet during pregnancy
