National Association of School Psychologists approved programs applying for Nationally Certified School Psychologist

The purpose of this paper is to examine the decision-making process of graduates of National Association of School Psychologists (NASP) approved programs who are eligible for the National Certification of School Psychologists (NCSP). Having graduated from a NASP approved program, graduates have met all prerequisites for the NCSP, but some still choose not to receive the certification. This research centers on the monetary value—including the application fee—of the certification; applicants have expressed indifference to receiving the NCSP because it will not provide an advantage, monetarily or otherwise, for advancement in their careers. Current New Jersey Association of School Psychologists (NJASP) members who have also graduated from NASP approved programs but do not possess the NCSP were surveyed. The data received from the sample is then evaluated against comparable certifications in other career fields. The findings indicated that those surveyed decided against receiving their NCSP because the value of the certification has little direct effect on career opportunity, placement, or advancement. The implications of this research suggest that higher application numbers for the NCSP may be possible if NASP approved programs made application for the certification a requirement upon graduation

Spin dynamics in a structurally ordered non-Fermi liquid compound: YbRh_2Si_2

Muon spin relaxation (muSR) experiments have been carried out at low temperatures in the non-Fermi-liquid heavy-fermion compound YbRh_2Si_2. The longitudinal-field muSR relaxation function is exponential, indicative that the dynamic spin fluctuations are homogeneous. The relaxation rate 1/T_1 varies with applied field as H^{-y}, y = 1.0 \pm 0.1, which implies a scaling law of the form \chi''(\omega) \propto \omega^{-y} f(\omega/T), \lim_{x\to0} f(x) = x for the dynamic spin susceptibility.Comment: 5 pages, 2 figures.

Three-dimension-printed custom-made prosthetic reconstructions: from revision surgery to oncologic reconstructions

Background The use of custom-made 3D-printed prostheses for reconstruction of severe bone defects in selected cases is increasing. The aims of this study were to evaluate (1) the feasibility of surgical reconstruction with these prostheses in oncologic and non-oncologic settings and (2) the functional results, complications, and outcomes at short-term follow-up. Methods We analyzed 13 prospectively collected patients treated between June 2016 and January 2018. Diagnoses were primary bone tumour (7 patients), metastasis (3 patients), and revision of total hip arthroplasty (3 patients). Pelvis was the most frequent site of reconstruction (7 cases). Functional results were assessed with MSTS score and complications according to Henderson et al. Statistical analysis was performed using Kaplan-Meier and log-rank test curves. Results At a mean follow-up of 13.7 months (range, 6 \u2013 26 months), all patients except one were alive. Oncologic outcomes show seven patients NED (no evidence of disease), one NED after treatment of metastasis, one patient died of disease, and another one was alive with disease. Overall survival was 100% and 80% at one and two years, respectively. Seven complications occurred in five patients (38.5%). Survival to all complications was 62% at two years of follow-up. Functional outcome was good or excellent in all cases with a mean score of 80.3%. Conclusion 3D-printed custom-made prostheses represent a promising reconstructive technique in musculoskeletal oncology and challenging revision surgery. Preliminary results were satisfactory. Further studies are needed to evaluate prosthetic design, fixation methods, and stability of the implants at long-ter

Magnetic-Field Induced Quantum Critical Point in YbRh2_2Si2_2

We report low-temperature calorimetric, magnetic and resistivity measurements on the antiferromagnetic (AF) heavy-fermion metal YbRh$_2$Si$_2$ (${T_N =}$ 70 mK) as a function of magnetic field $B$. While for fields exceeding the critical value ${B_{c0}}$ at which ${T_N\to0}$ the low temperature resistivity shows an ${AT^2}$ dependence, a ${1/(B-B_{c0})}$ divergence of ${A(B)}$ upon reducing $B$ to ${B_{c0}}$ suggests singular scattering at the whole Fermi surface and a divergence of the heavy quasiparticle mass. The observations are interpreted in terms of a new type of quantum critical point separating a weakly AF ordered from a weakly polarized heavy Landau-Fermi liquid state.Comment: accepted for publication in Phys.

Effect of chemical substitution and pressure on YbRh2Si2

We carried out electrical resistivity experiments on (Yb,La)Rh2Si2 and on Yb(Rh,Ir)2Si2 under pressure and in magnetic fields. YbRh2Si2 exhibits a weak antiferromagnetic transition at atmospheric pressure with a N\'eel temperature of only T_N = 70 mK. By applying a small magnetic field T_N can be continuously suppressed to T=0 at B_c = 60 mT (B_|_c) driving the system to a quantum critical point (QCP). On applying external pressure the magnetic phase is stabilized and T_N(p) is increasing as usually observed in Yb-based heavy-fermion metals. Substituting Yb by La or Rh by Ir allows to create a negative chemical pressure, La (Ir) being smaller than Yb (Rh), and eventually to drive YbRh2Si2 to a pressure controlled QCP. In this paper we compare the effect of external hydrostatic pressure and chemical substitution on the ground-state properties of YbRh2Si2.Comment: 4 pages, 5 figures, proceedings paper of the QCNP0

Ceria Catalysts at Nanoscale: How Do Crystal Shapes Shape Catalysis?

Engineering the shape and size of catalyst particles and the interface between different components of heterogeneous catalysts at the nanometer level can radically alter their performances. This is particularly true with CeO2-based catalysts, where the precise control of surface atomic arrangements can modify the reactivity of Ce4+/Ce3+ ions, changing the oxygen release/uptake characteristics of ceria, which, in turn, strongly affects catalytic performance in several reactions like CO, soot, and VOC oxidation, WGS, hydrogenation, acid base reactions, and so on. Despite the fact that many of these catalysts are polycrystalline with rather ill-defined morphologies, experimental and theoretical studies on well-defined nanocrystals have clearly established that the exposure of specific facets can increase/decrease surface Oxygen reactivity and metal-support interaction (for supported metal nanoparticles), consequently affecting catalytic reactions. Here, we want to address the most recent developments in this area, showing that shape (and size) modification, surface/face reconstruction, and faceting of ceria at the nanoscale level can offer an important tool to govern activity and stability in several reactions and imagine how this could contribute to future developments

Potential of Ceria-Zirconia-Based Materials in Carbon Soot Oxidation for Gasoline Particulate Filters

ZrO(2)and Ce(0.8)Zr(0.2)O(2)mixed oxides were prepared and tested in the oxidation of carbon soot at different oxygen partial pressures and degrees of catalyst/soot contact to investigate their activity under typical gasoline direct injection (GDI) operating conditions. Under reductive atmospheres, generation of oxygen vacancies occurs in Ce0.8Zr0.2O2, while no reduction is observed on ZrO2. Both materials can oxidize carbon under high oxygen partial pressures; however, at low oxygen partial pressures, the presence of carbon can contribute to the reduction of the catalyst and formation of oxygen vacancies, which can then be used for soot oxidation, increasing the overall performance. This mechanism is more efficient in Ce(0.8)Zr(0.2)O(2)than ZrO2, and depends heavily on the interaction and the degree of contact between soot and catalyst. Thus, the ability to form oxygen vacancies at lower temperatures is particularly helpful to oxidize soot at low oxygen partial pressures, and with higher CO(2)selectivity under conditions typically found in GDI engine exhaust gases

Teaching and learning of environmental education: contributions of subjects at the São Paulo University

[Resumo] A partir de 1983, na Escola Superior de Agricultura “Luiz de Queiroz”, da Universidade de São Paulo (ESALQ/USP), inicia-se um processo de desenvolvimento da área de educação ambiental, que culmina com a criação, já nos anos 2000, de disciplinas para graduações e pós-graduações. As disciplinas têm em comum a perspectiva de estudantes protagonizarem a sua própria formação como profissionais e cidadãos/cidadãs. Ancoradas em perspectivas teóricas relacionadas ao ambientalismo, utopismo e educação emancipatória, desenvolvem duas técnicas destacadas no presente artigo: Mínima/Máxima Intervenção Possível (MIP) e Diário de Bordo. A pesquisa que fundamenta o presente artigo é qualitativa, utilizando a observação participante, avaliações processuais e intervenções educadoras junto aos estudantes das mencionadas disciplinas. Os resultados demonstraram-se positivos sob o ponto de vista do envolvimento e participação, restando questionamentos sobre o real aprofundamento de conteúdos específicos. É perceptível o desenvolvimento do protagonismo, autonomia e capacidade de articulação de conteúdos e ações nos estudantes. O uso das técnicas citadas sugere favorecer o desenvolvimento de sujeitos comprometidos com transformações de seu território e apresenta-se como proposta de aprimoramento de processos de ensino aprendizagem na educação superior.[Abstract] A process of development of the environmental education area began in 1983 at Escola Superior de Agricultura “Luiz de Queiroz”, of Universidade de São Paulo (ESALQ/USP). In the 2000s were creating subjects for graduation and post-graduation. The disciplines have in common the perspective of students to carry out their own formation as professionals and citizens. The theoretical perspectives are based to environmentalism, utopianism and emancipatory education. They develop two techniques highlighted in this article: Minimum / Maximum Possible Intervention (MIP) and Logbook. The research that bases the present article is qualitative, using participant observation, procedural evaluations and educative interventions with the students of the mentioned disciplines. The results were positive from the point of view of involvement and participation, remaining questions about the actual deepening of specific contents. It is noticeable the development of the protagonism, autonomy and capacity of articulation of contents and actions in the students. The use of the mentioned techniques suggests in favor the development of subjects committed with transformations of their territory and presents itself as proposal of improvement of teaching learning processes in higher education
