Expanding the Landscape of Wholeness: The Spirituality of Teacher Preparation. A Response to Reconstituting Teacher Education: Toward Wholeness in an Era of Monumental Challenges

This article is a response to a paper arguing for a shift from “oneness” to “wholeness” as a democratic principle when reconceptualizing teacher education in a time of large-scale social change. While the paper provides compelling arguments for wholeness as a tool to address social injustice, the discussion is framed primarily through a humanist lens. This response is an invitation to expand the definition of wholeness to include spirituality as core to what it means to be human and whole. It addresses the importance of spirituality in teacher education when considering culturally responsive pedagogy, the religion-spirit distinction, the source of the call to teach, and the outer-technical and inner-heart paradox of teaching. Examples from educators combining spirituality and social justice are explored

Periodicities in data observed during the minimum and the rising phase of solar cycle 23; years 1996 - 1999

Three types of observations: the daily values of the solar radio flux at 7 frequencies, the daily international sunspot number and the daily Stanford mean solar magnetic field were processed in order to find all the periodicities hidden in the data. Using a new approach to the radio data, two time series were obtained for each frequency examined, one more sensitive to spot magnetic fields, the other to large magnetic structures not connected with sunspots. Power spectrum analysis of the data was carried out separately for the minimum (540 days from 1 March 1996 to 22 August 1997) and for the rising phase (708 days from 23 August 1997 to 31 July 1999) of the solar cycle 23. The Scargle periodograms obtained, normalized for the effect of autocorrelation, show the majority of known periods and reveal a clear difference between the periodicities found in the minimum and the rising phase. We determined the rotation rate of the `active longitudes' in the rising phase as equal to 444.4 $\pm$ 4 nHz (26\fd0 \pm 0\fd3). The results indicate that appropriate and careful analysis of daily radio data at several frequencies allows the investigation of solar periodicities generated in different layers of the solar atmosphere by various phenomena related to the periodic emergence of diverse magnetic structures.Comment: 15 pages, 8 figure

A Longitudinal Mixed-Methods Study of IPE Students\u27 Perceptions of Health Profession Groups: Revisiting the Contact Hypothesis

Abstract Despite the increasing momentum and integration of Interprofessional Education (IPE) programs into various health professions curriculum, the findings of previous research are mixed regarding the impact these programs have on dismantling or even stifling students’ negative stereotypes of health professions. Of those studies that find “positive” shifts in students’ perceptions, elements of the Contact Hypothesis are frequently employed to support these apparent shifts. However, there is often little to no attention paid to how intergroup contact within IPE programs actually impacts students’ stereotypes. To examine if students’ attitudes towards other health professions shifted following participation in an IPE program 528 students from six different health profession training programs completed the Student Stereotypes Rating Questionnaire (SSRQ) assessing their perceptions/stereotypes of their own and other health professions at the beginning and end of a two-year IPE program. Following the finding that students’ attitudes did indeed positively shift, interviews with 20 students were analyzed to explore how contact within the program may have impacted their perceptions. The findings lend support for the Contact Hypothesis and the authors argue that opportunities to informally interact and socialize may be more influential on students’ attitudes than the formal aspects of IPE programs, and that models of cognitive representation that emphasis more personalization (as opposed to differentiation) may be more effective tools in examining how intergroup contact within IPE affects students’ stereotypes. Measureable Learning Objectives: a.) Provide a better understanding of the Contact Hypothesis and models of cognitive representations, and how these approaches can be utilized effectively in IPE research, b.) Provide an example of effective and efficient mixed-methods research in evaluating IPE programs, and c.) Provide tools (both methodological and theoretical) to better assess IPE outcomes

Creation of wear-resistant near-surface-layers with inhomogeneous structure on NiTi alloy by ion implantation technology

In the present study we report the changes in the modified near-surface layer on NiTi shape memory alloy, caused by ion implantation as well as their influence on the structure and mechanical properties of this material. Experimental results of an inhomogeneous structure and tribological properties of implanted NiTi are discussed in this paper

Extrinsic and Intrinsic Elements that may Impact Students’ Perceptions of and Willingness to Internalize Interprofessional Education Program Goals

ABSTRACT An increasing number of health profession education institutions are constructing and implementing Interprofessional Education (IPE) programs. Various evaluative efforts are therefore underway to explore students’ perceptions of these programs, nuances of the interdisciplinary interactions within programs, and the potential long-term impact of these programs on students’ mentality towards team-based, collaborative care. This study, however, examines how elements specific to and outside of an IPE program may impact students’ perceptions of the program and their willingness to engage with prominent aims and goals of IPE. In-depth, semi-structured interviews were conducted with 16 students from varying disciplines at the end of years one and two of a 2-year IPE program. Data were analyzed utilizing a multi-step inductive and deductive process to identity consistent patterns in students’ perceptions of and attitudes toward the program from year one to year two. The data show that although students felt they understood the value and importance of interprofessionality and team-based care, there were elements that were intrinsic (assignments, time constraints, level of accountability) and extrinsic (anticipatory socialization, lack of professional identity) to the IPE program that impacted their perceptions of the program, and that these perceptions, in turn, affected their level of commitment to the program. Further examination of these factors suggests that students struggled specifically with how their program negotiated: a.) fostering understanding of each specific discipline/profession as well as advocating for team-based care, and b.) the informal vs formal nature of the program. The findings of this study shed a valuable new light on how elements related to an IPE program’s structure and implementation as well as factors outside of the program may affect and influence the acculturation of person-centered team-based care.

Charmonium and open charm production in nuclear collisions at SPS/FAIR energies and the possible influence of a hot hadronic medium

We provide predictions for charmonium and open charm production in nuclear collisions at SPS/FAIR energies within the framework of the statistical hadronization model. The increasing importance at lower energies of Lambda_c production is demonstrated and provides a challenge for future experiments. We also demonstrate that, because of the large charm quark mass and the different timescales for charm quark and charmed hadron production, possible modifications of charmed hadrons in the hot hadronic medium do not lead to measurable changes in cross sections for D-meson production. A possible influence of medium effects can be seen, however, in yields of charmonium. These effects are visible at all energies and results are presented for the energy range between charm threshold and RHIC energy.Comment: 12 pages, 4 figures; v2: slightly revised text and updated calculations; v3: slightly enhanced discussion, one more ref.; data file with calculations will be available at http://www-linux.gsi.de/~andronic/physics/charm

Hadron production in central nucleus-nucleus collisions at chemical freeze-out

We analyze the experimental hadron yield ratios for central nucleus-nucleus collisions in terms of thermal model calculations over a broad energy range, $\sqrt{s_{NN}}$=2.7-200 GeV. The fits of the experimental data with the model calculations provide the thermal parameters, temperature and baryo-chemical potential at chemical freeze-out. We compare our results with the values obtained in other studies and also investigate more technical aspects such as a potential bias in the fits when fitting particle ratios or yields. Using parametrizations of the temperature and baryonic chemical potential as a function of energy, we compare the model calculations with data for a large variety of hadron yield ratios. We provide quantitative predictions for experiments at LHC energy, as well as for the low RHIC energy of 62.4 GeV. The relation of the determined parameters with the QCD phase boundary is discussed.Comment: 38 pages, 25 figures - accepted to Nucl. Phys. A; v2: update fits of 4pi data,update on NA44 data at top SPS, fits at top RHIC without resonances; v3: include fits of absolute yields (appendix).
