Dispositions: Real-Time Active Practice

This longitudinal case study followed new teachers from one small undergraduate pre-service program into the first years of teaching. The researcher’s initial study (Hughes, 2014) examined dispositional awareness and development of participants using personal interview data from program graduates, interview data from program faculty, and archived course artifacts. The current study extends the research and shines a light on dispositional development from pre-service through the fourth year of teaching. Using personal interviews, a focus group meeting, and archived course artifacts, the study affirms the significance of dispositions in pre-service preparation and professional practice. The study validates that participants carry dispositional awareness into the fourth year of teaching and also reveals a variety of strategies that new teachers use to grow dispositions. Of significance is the finding that new teachers require a set of dispositional practices for career longevity. This finding exposes the need for increased professional development opportunities related to dispositions during and beyond the first years of teaching

Mighty Teacher Mentors

Teaching is about cultivating curiosity, fostering a love for course content, and making connections with students. Educators who serve as mentors and pass on their passions for the profession and a love for sharing their craft can thoughtfully encourage prospective teachers into the field. This article captures and links one educator’s journey with the teaching mentors that encouraged a contagious love for teaching and learning in her. The article provides encouragement and practical suggestions for educators that desire to learn from authentic mentors and pay it forward with others in the faith. The article is adapted from a chapel talk given at Westmont College by the author on February 24, 2014

Can Resilience Be Our Teacher Super-power?

Teaching is courageous work. Today\u27s teachers face heavy workloads and growing emotional responsibilities as K-12 students and families face complicated hurdles and issues such as mental health issues, immigration, and natural disasters. This essay names resilience, grit, and perseverance as essential dispositions needed to tackle the daily hurdles and unexpected circumstances found in the classroom and pre-service teacher preparation. The author’s reflections lead to practical recommendations with the intention to nurture and cultivate resilience in teachers and school communities

Space structure vibration modes: How many exist? Which ones are important?

This report attempts to shed some light on the two issues raised in the title, namely, how many vibration modes does a real structure have, and which of these modes are important? The surprise-free answers to these two questions are, respectively, an infinite number and the first several modes. The author argues that the absurd subspace (all but the first billion modes) is not a strength of continuum modeling, but, in fact, a weakness. Partial differential equations are not real structures, only mathematical models. This note also explains (1) that the PDE model and the finite element model are, in fact, the same model, the latter being a numerical method for dealing with the former, (2) that modes may be selected on dynamical grounds other than frequency alone, and (3) that long slender rods are useful as primitive cases but dangerous to extrapolate from

Linear statistics for zeros of Riemann's zeta function

We consider a smooth counting function of the scaled zeros of the Riemann zeta function, around height T. We show that the first few moments tend to the Gaussian moments, with the exact number depending on the statistic considered

Process for synthesizing and formulating condensed ring polymers

Chemical process for forming low molecular weight, fully cyclized heteroaromatic prepolymers under conditions which limit chain extension or branching is described. Exact procedures used in conducting chemical reaction are defined. Advantages of process over conventional methods are presented

New methods for B meson decay constants and form factors from lattice NRQCD

We determine the normalisation of scalar and pseudoscalar current operators made from non-relativistic $b$ quarks and Highly Improved Staggered light quarks in lattice Quantum Chromodynamics (QCD) through $\mathcal{O}(\alpha_s)$ and $\Lambda_{\text{QCD}}/m_b$. We use matrix elements of these operators to extract $B$ meson decay constants and form factors, then compare to those obtained using the standard vector and axial-vector operators. This provides a test of systematic errors in the lattice QCD determination of the $B$ meson decay constants and form factors. We provide a new value for the $B$ and $B_s$ meson decay constants from lattice QCD calculations on ensembles that include $u$, $d$, $s$ and $c$ quarks in the sea and those which have the $u/d$ quark mass going down to its physical value. Our results are $f_B=0.196(6)$ GeV, $f_{B_s}=0.236(7)$ GeV and $f_{B_s}/f_B =1.207(7)$, agreeing well with earlier results using the temporal axial current. By combining with these previous results, we provide updated values of $f_B=0.190(4)$ GeV, $f_{B_s}=0.229(5)$ GeV and $f_{B_s}/f_B = 1.206(5)$.Comment: 14 pages, 10 figure

The status of environmental satellites and availability of their data products

The latest available information about the status of unclassified environmental satellite (flown by the United States) and their data products is presented. The type of environmental satellites discussed include unmanned earth resource and meteorological satellites, and manned satellites which can act as a combination platform for instruments. The capabilities and data products of projected satellites are discussed along with those of currently operating systems

Method for forming pyrrone molding powders and products of said method

The formation of pyrrone resins of the ladder or semiladder structure is described. The technique involves initial formation of fully cyclized prepolymers having an average degree of polymerization of about 1.5, one with acidic terminal groups, another with amine terminal groups. Thereafter the prepolymers are intimately admixed on a 1:1 stoichiometric basis. The resulting powder mixture is molded at elevated pressures and temperatures to form a fully cyclized resin
