Domain State Occurring in the de Haas-van Alphen Effect in Silver

Hysteresis has been observed in de Haas-van Alphen measurements of the Condon domains in silver, and it shows the first-order nature of the transition to the domain state. The hysteresis, and thus the first-order nature, is manifested in a nonlinear effect where a double-valued response of the amplitude with the applied external field is observed

Engaging In Self-Care: Do Mental Health Care Providers Practice What They Preach?

Self-care has been identified as a critical protective factor against the adverse effects of career-related stress among mental health care professionals. The need for utilization of adequate self-care practices among mental health care professionals remains critical with the number of mental health care professionals endorsing clinically significant levels of anxiety, depression, and suicidal ideations. Research has identified the need and importance of self-care among mental health care providers as well as the adverse consequences of inadequate self-care. This literature review examined the methods and strategies mental health care providers are using to engage in self-care including complementary and alternative methods. This paper also explored the literature to identify whether mental health care providers use the strategies they recommend to their clients. An extensive search was conducted within EBSCO and ProQuest to review a large number of journals and articles to evaluate these areas. Suggestions for clinicians to address their self-care are included based on this review. Implications for clinicians and their clinical work are discussed as well as future research directions

Cultivating Textbook Alternatives From the Ground Up: One Public University’s Sustainable Model for Open and Alternative Educational Resource Proliferation

This note from the field reviews the sustainability of an institution-wide program for adopting and adapting open and alternative educational resources (OAER) at Kansas State University (K-State). Developed in consult of open textbook initiatives at other institutions and modified around the needs and expectations of K-State students and faculty, this initiative proposes a sustainable means of incentivizing faculty participation via institutional support, encouraging the creation and maintenance of OAER through recurring funding, promoting innovative realizations of “educational resources” beyond traditional textbooks, and rallying faculty participation in adopting increasingly open textbook alternatives. The history and resulting structure of the initiative raise certain recommendations for how public universities may sustainably offset student textbook costs while also empowering the pedagogies of educators via a more methodical approach to adopting open materials

Ytterbium divalency and lattice disorder in near-zero thermal expansion YbGaGe

While near-zero thermal expansion (NZTE) in YbGaGe is sensitive to stoichiometry and defect concentration, the NZTE mechanism remains elusive. We present x-ray absorption spectra that show unequivocally that Yb is nearly divalent in YbGaGe and the valence does not change with temperature or with nominally 1% B or 5% C impurities, ruling out a valence-fluctuation mechanism. Moreover, substantial changes occur in the local structure around Yb with B and C inclusion. Together with inelastic neutron scattering measurements, these data indicate a strong tendency for the lattice to disorder, providing a possible explanation for NZTE in YbGaGe.Comment: 4 pages, 4 figure, supplementary inf

Experimental electronic heat capacities of α−\alpha- and δ−\delta-Plutonium; heavy-fermion physics in an element

We have measured the heat capacities of $\delta-$Pu$_{0.95}$Al$_{0.05}$ and $\alpha-$Pu over the temperature range 2-303 K. The availability of data below 10 K plus an estimate of the phonon contribution to the heat capacity based on recent neutron-scattering experiments on the same sample enable us to make a reliable deduction of the electronic contribution to the heat capacity of $\delta-$Pu$_{0.95}$Al$_{0.05}$; we find $\gamma = 64 \pm 3$ mJK$^{-2}$mol$^{-1}$ as $T \to 0$. This is a factor $\sim 4$ larger than that of any element, and large enough for $\delta-$Pu$_{0.95}$Al$_{0.05}$ to be classed as a heavy-fermion system. By contrast, $\gamma = 17 \pm 1$ mJK$^{-2}$mol$^{-1}$ in $\alpha-$Pu. Two distinct anomalies are seen in the electronic contribution to the heat capacity of $\delta-$Pu$_{0.95}$Al$_{0.05}$, one or both of which may be associated with the formation of the $\alpha'-$ martensitic phase. We suggest that the large $\gamma$-value of $\delta-$Pu$_{0.95}$Al$_{0.05}$ may be caused by proximity to a quantum-critical point.Comment: 4 pages, 4 figure

Dynamic Stabilization of Cubic AuZn

A recently developed temperature-dependent effective potential method is employed to study the martensitic phase transformation in AuZn. This method is based on ab initio molecular dynamics and allows to obtain finite-temperature lattice vibrational properties. We show that the transversal acoustic TA_2[110] mode associated with the phase transition is stabilized at 300 K. Temperature evolution of single-phonon dynamic structure factor at the wave vector q=1/3[1,1,0], associated with phonon softening and Fermi surface nesting, was also studied

Coulomb-U and magnetic moment collapse in δ\delta-Pu

The around-the-mean-field version of the LDA+U method is applied to investigate electron correlation effects in $\delta$-Pu. It yields a non-magnetic ground state of $\delta-$Pu, and provides a good agreement with experimental equilibrium volume, bulk modulus and explains important features of the photoelectron spectra

Boise State Open Educational Resources Staff Training

Join colleagues from the Library, eCampus, Learning Technology Solutions and the IDEA Shop for a morning of learning about OER. Goals include: 1) Participants will learn about OER and how we can help support faculty interested in adopting OER. 2) Participants will meet each other, learn what we do in our respective departments and how we can work together
