Relationships among curricular and extra-curricular activities and fundamental competencies for working persons
Two kinds of data analysis methods were applied to the retrospective survey data collected by Morita, Shimizu, and Funaba (2012) to determine which university education programs and activities influence the alumni’s job performance. The result by correspondence analysis among university programs and activities and the fundamental competencies for working persons defined by the Japanese Ministry of Economy, Trade and Industry (2007) indicated the following four clusters: (1) seminar and one’s ability to deliver opinions clearly, to analyze the status quo, and to clarify issues; (2) curriculum and one’s foreign language ability; (3) extra-curricular activities and one’s ability to listen carefully to others’ opinions and to influence and involve others; and (4) one’s activities outside university and the ability to create new values. The causal relationships among the actual degrees of curricular and extra-curricular activities in university, the utility of such activities in university life, and the three factors extracted from the responses to the questions of the fundamental competencies were also analyzed by the path analysis method. Activities outside university affected most significantly the alumni’s ability to solve issues, while a few activitiesrelated to university life affected their ability to collaborate with various people and to manage stress. The methodological issues with the alumni survey were also discussed along with the implications of these findings.大学における教育プログラムと活動が,卒業生の仕事の遂行に与える影響について明らかにするために,森田・清水・船場(2011)によって収集された回想的調査データに2 種類の分析方法論を適用した。経済産業省(2007)によって定義された社会人基礎力と大学におけるプログラム,活動の関係についての対応分析による結果から,以下の4クラスタが得られた:⑴ゼミと自分の意見を分かりやすく伝える力,現状を分析し課題を明らかにする力,⑵講義と語学力,⑶正課外活動と相手の意見を丁寧に聴く力,他人に働きかけ巻き込む力,そして,⑷学外での活動と新しい価値を生み出す力,である。大学の正課・正課外活動,大学生活における幾つかの活動の有用性,そして基礎能力についての質問項目から抽出された3つの因子の因果関係について,パス解析による分析を行った。学外での活動は,課題解決力に対して最も有意に影響していた。大学生活における少数の活動が対人関係力,ストレス耐性力に影響していた。卒業生調査における方法論的問題とこれらの知見について考察を行った
Atmospheric transport and chemistry of trace gases in LMDz5B: evaluation and implications for inverse modelling
Representation of atmospheric transport is a major source of error in the estimation of greenhouse gas sources and sinks by inverse modelling. Here we assess the impact on trace gas mole fractions of the new physical parameterizations recently implemented in the atmospheric global climate model LMDz to improve vertical diffusion, mesoscale mixing by thermal plumes in the planetary boundary layer (PBL), and deep convection in the troposphere. At the same time, the horizontal and vertical resolution of the model used in the inverse system has been increased. The aim of this paper is to evaluate the impact of these developments on the representation of trace gas transport and chemistry, and to anticipate the implications for inversions of greenhouse gas emissions using such an updated model. Comparison of a one-dimensional version of LMDz with large eddy simulations shows that the thermal scheme simulates shallow convective tracer transport in the PBL over land very efficiently, and much better than previous versions of the model. This result is confirmed in three-dimensional simulations, by a much improved reproduction of the radon-222 diurnal cycle. However, the enhanced dynamics of tracer concentrations induces a stronger sensitivity of the new LMDz configuration to external meteorological forcings. At larger scales, the inter-hemispheric exchange is slightly slower when using the new version of the model, bringing them closer to observations. The increase in the vertical resolution (from 19 to 39 layers) significantly improves the representation of stratosphere/troposphere exchange. Furthermore, changes in atmospheric thermodynamic variables, such as temperature, due to changes in the PBL mixing modify chemical reaction rates, which perturb chemical equilibriums of reactive trace gases. One implication of LMDz model developments for future inversions of greenhouse gas emissions is the ability of the updated system to assimilate a larger amount of high-frequency data sampled at high-variability stations. Others implications are discussed at the end of the paper
Magnetic properties of Fe implanted SrTiO3 perovskite crystal
The results of investigations of magnetic properties of SrTiO3 perovskite crystal implanted with 40 keV Fe ions at the fluencies between 0.5 × 1017 and 1.5 × 1017 ion/cm2 are presented. It has been revealed that high-fluency implantation with Fe ions results in the formation of a granular metal particulate composite in the irradiated near-surface layer of SrTiO3 substrate, which exhibits remarkable ferromagnetic behavior. The measurements of the temperature dependence of the magnetic moment showed that the samples exhibit blocking temperature at about 350 K, above which a superparamagnetic behavior has been observed. Ferromagnetic ordering and magnetic hysteresis loops were observed in Fe implanted SrTiO3 at the temperatures lower than 350 K. It has been shown that the magnetization of the ferromagnetic state depends on the fluency of implantation. © 2013 Elsevier Ltd. All rights reserved
Magnetic resonance and magnetization in Fe implanted BaTiO3 crystal
© 2014 Elsevier B.V. All rights reserved. The results of investigations of the magnetic properties of Fe implanted barium titanate (BaTiO3) perovskite crystal are presented. It has been revealed that the implantation with Fe+ ions at a fluence of 0.75×1017 ions/cm2 results in the formation of iron nanoparticles with mean size of 5 nm in the implanted surface layer of BaTiO3 substrate. Room temperature magnetic resonance measurements have shown Electron Paramagnetic Resonance (EPR) spectra originated from Fe3+ ions in the BaTiO3 substrate, as well as ferromagnetic resonance (FMR) spectrum from the Fe-implanted surface layer, exhibiting the out-of-plane uniaxial magnetic anisotropy. On the other hand, Vibrating Sample Magnetometer (VSM) measurements of the static magnetization have shown that the composite Fe:BaTiO3 system displays superparamagnetic response at room temperature, and evident ferromagnetic behavior with an easy-plane magnetic anisotropy at temperature below 100 K. The observed magnetic anisotropy is discussed on a model of strong magnetic dipolar interaction between superparamagnetic nanoparticles of iron within the granular composite film formed in a result of the high-fluence implantation
Magnetic phase composition of strontium titanate implanted with iron ions
Thin magnetic films were synthesized by means of implantation of iron ions into single-crystalline (1 0 0) substrates of strontium titanate. Depth-selective conversion electron Mössbauer spectroscopy (DCEMS) indicates that origin of the samples magnetism is α-Fe nanoparticles. Iron-substituted strontium titanate was also identified but with paramagnetic behaviour at room temperature. Surface magneto-optical Kerr effect (SMOKE) confirms that the films reveal superparamagnetism (the low-fluence sample) or ferromagnetism (the high-fluence sample), and demonstrate absence of magnetic in-plane anisotropy. These findings highlight iron implanted strontium titanate as a promising candidate for composite multiferroic material and also for gas sensing applications. © 2011 Elsevier Ltd. All rights reserved
Structural and magnetic studies of Co and Fe implanted BaTiO 3 crystals
Singly-charged Co or Fe ions with energy 40 keV were implanted into single-domain ferroelectric plates of barium titanate (BaTiO 3) with high fluences in the range of (0.5-1.5) × 10 17 ion/cm 2 to create new magnetoelectric materials. Scanning electron microscopy (SEM) and conversion electron Mössbauer spectroscopy (CEMS) studies have shown that high-fluence implantation with 3d-ions results in formation of cobalt or iron nanoparticles in the near-surface irradiated region of perovskite-type crystal. With increasing the fluence, the both Co- and Fe-implanted BaTiO 3 samples reveal at first superparamagnetic, and then ferromagnetic properties at room temperature. Analysis of magnetic hysteresis loops measured in the in-plane and out-of-plane geometries have shown that ferromagnetic BaTiO 3:Co(Fe) nanocomposite layers display the "easy plane" magnetic anisotropy similar to that found for thin granular magnetic films. Together with our previous observation of the magnetoelectric effect in these samples, our structural and magnetic investigations show that the ion implantation is suitable to synthesize the desired magnetoelectric nanocomposite materials. © 2011 Elsevier B.V.

High resolution mapping of a novel late blight resistance gene Rpi-avll, from the wild Bolivian species Solanum avilesii
Both Mexico and South America are rich in Solanum species that might be valuable sources of resistance (R) genes to late blight (Phytophthora infestans). Here, we focus on an R gene present in the diploid Bolivian species S. avilesii. The genotype carrying the R gene was resistant to eight out of 10 Phytophthora isolates of various provenances. The identification of a resistant phenotype and the generation of a segregating population allowed the mapping of a single dominant R gene, Rpi-avl1, which is located in an R gene cluster on chromosome 11. This R gene cluster is considered as an R gene “hot spot”, containing R genes to at least five different pathogens. High resolution mapping of the Rpi-avl1 gene revealed a marker co-segregating in 3890 F1 individuals, which may be used for marker assisted selection in breeding programs and for further cloning of Rpi-avl
Ion beam synthesis and investigation of nanocomposite multiferroics based on barium titanate with 3d metal nanoparticles
Samples of nanocomposite multiferroics have been synthesized by implantation of Co+, Fe+, and Ni+ ions with an energy of 40 keV into ferroelectric barium titanate plates to doses in the range (0.5-1.5) × 1017 ions/cm2. It has been found that nanoparticles of metallic iron, cobalt, or nickel are formed in the barium titanate layer subjected to ion bombardment. With an increase in the implantation dose, the implanted samples sequentially exhibit superparamagnetic, soft magnetic, and, finally, strong ferromagnetic properties at room temperature. The average sizes of ion-synthesized 3d-metal nanoparticles vary in the range from 5 to 10 nm depending on the implantation dose. Investigation of the orientation dependence of the magnetic hysteresis loops has demonstrated that the samples show a uniaxial ("easy plane") magnetic anisotropy typical of thin granular magnetic films. Ferromagnetic BaTiO3: 3d metal samples are characterized by a significant shift of the ferromagnetic resonance signal in an external electric field, as well as by a large (in magnitude) magnetodielectric effect at room temperature. These results indicate that there is a strong magnetoelectric coupling between the ferroelectric barium titanate matrix and ion-synthesized nanoparticles of magnetic metals. © 2013 Pleiades Publishing, Ltd
Comparison of outcomes following a cytological or histological diagnosis of malignant mesothelioma
Background: Survival with the epithelioid subtype of malignant mesothelioma (MM) is longer than the biphasic or sarcomatoid subtypes. There is concern that cytology-diagnosed epithelioid MM may underdiagnose the biphasic subtype. This study examines survival differences between patients with epithelioid MM diagnosed by cytology only and other subtypes diagnosed by histology. Methods: Demographics, diagnosis method, MM subtype and survival were extracted from the Western Australia (WA) Mesothelioma Registry, which records details of all MM cases occurring in WA. Results: A total of 2024 MM cases were identified over 42 years. One thousand seven hundred forty-four (86.2%) were male, median (IQR) age was 68.6 (60.4–77.0) years. A total of 1212 (59.9%) cases were identified as epithelioid subtype of which 499 (41.2%) were diagnosed using fluid cytology only. Those with a cytology-only diagnosis were older than the histology group (median 70.2 vs 67.6 years, P<0.001), but median survival was similar (cytology 10.6 (5.5–19.2) vs histology 11.1 (4.8–19.8) months, P=0.727) and Cox regression modelling adjusting for age, sex, site and time since first exposure showed no difference in survival between the different diagnostic approaches. Conclusions: Survival of cytologically and histologically diagnosed epithelioid MM cases does not differ. A diagnostic tap should be considered adequate to diagnose epithelioid MM without need for further invasive testing
