Early Career Special Education Teachers Perceived Value of Being Mentored by General Education Teachers

Special education induction research has examined mentor support and working conditions of early career special education teachers (ECSETs) for over 20 years. Recently researchers provide specialized professional development to mentors based on suggestions of special education induction research. Drawing on quality indicators of single-subject research and the belief that social validity data is valuable, we used qualitative methods to discover ECSETs’ perceptions of the intervention and the helpfulness of the mentors. We then compared responses of the participants with the existing research in special education induction. Findings indicate the participants appreciated the specialized training for their mentors and perceived their mentors as helpful and affected their teaching experiences. However, similar to existing research, the participants had mixed feelings about their working conditions

Rethinking process guidance for selecting software components

© Springer-Verlag Berlin Heidelberg 2002. This paper reports the results of ongoing research into compo-nent-based software engineering (CBSE) in the European banking sector as part of the EU-funded BANKSEC project. The importance of complex non-functional requirements such as dependability and security presents new challenges for CBSE. The paper presents BANKSEC’s vision of an integrated software tool that will provide process advice for component procurement teams who are tackling these new problems. The basis for this process guidance is a situation meta-model that enables the software tool to infer properties about the current status of the selection process and recommend process guidance relevant to this situation

Compressibility of CeMIn5Ce M In_5 and Ce2MIn8Ce_2 M In_8 (M = Rh, Ir and Co) Compounds

The lattice parameters of the tetragonal compounds Ce$M$In$_{5}$ and Ce$_{2}M$In$_{8}$($M=$Rh, Ir and Co) have been studied as a function of pressure up to 15 GPa using a diamond anvil cell under both hydrostatic and quasihydrostatic conditions at room temperature. The addition of $M$In$_{2}$ layers to the parent CeIn$_{3}$ compound is found to stiffen the lattice as the 2-layer systems (average of bulk modulus values $B_{0}$ is 70.4 GPa) have a larger $B_{0}$ than CeIn$_{3}$ (67 GPa), while the 1-layer systems with the are even stiffer (average of $B_{0}$ is 81.4 GPa). Estimating the hybridization using parameters from tight binding calculations shows that the dominant hybridization is $fp$ in nature between the Ce and In atoms. The values of $V_{pf}$ at the pressure where the superconducting transition temperature $T_{c}$ reaches a maximum is the same for all Ce$M$In$_{5}$ compounds. By plotting the maximum values of the superconducting transition temperature $T_{c}$ versus $c/a$ for the studied compounds and Pu-based superconductors, we find a universal $T_{c}$ versus $c/a$ behavior when these quantities are normalized appropriately. These results are consistent with magnetically mediated superconductivity.Comment: Updated version resubmitted to Phys. Rev.

Importance of the onion leaf twister disease in Ghana and the effect of Trichoderma asperellium on the mycelial growth and sporulation of the causal agent

Abstract Studies were carried out to determine the disease incidence and severity of the onion leaf twister disease in the Eastern Region of Ghana to confirm the aetiology of the disease in the country. Field survey was carried out in two districts of the Eastern Region and the disease incidence and severity were measured. The causal agent was isolated on media and identified using morphological characteristics, and polymerase chain reaction with the species specific primer CgInt combined with ITS4 primer. The effect of Trichoderma asperellium on the mycelial growth and sporulation of the causal agent of the disease were determined. The results showed that the disease incidence was 43.6 per cent and 62.5 per cent in the Kwahu South and Fanteakwa districts, respectively, with severity of 0.8 and 2.7 respectively, on a scale of 1 – 5. The causal agent was confirmed as Colletotrichum gloeosporioides. The bio-agent, T. asperellium was able to significantly suppress the mycelial growth and sporulation of the pathogen infecting the onions

Localized f electrons in CexLa1-xRhIn5: dHvA Measurements

Measurements of the de Haas-van Alphen effect in CexLa1-xRhIn5 reveal that the Ce 4f electrons remain localized for all x, with the mass enhancement and progressive loss of one spin from the de Haas-van Alphen signal resulting from spin fluctuation effects. This behavior may be typical of antiferromagnetic heavy fermion compounds, inspite of the fact that the 4f electron localization in CeRhIn5 is driven, in part, by a spin-density wave instability.Comment: 4 pages, 4 figures, submitted to PR
