Molecular Phylogenetic Relationships of Flightless Beetles Belonging to the Genus Mesechthistatus Breuning, (Coleoptera: Cerambycidae) Inferred from Mitochondrial COI Gene Sequences.

The longicorn beetles belonging to the genus MesechthistatusBreuning., 1950 (Coleoptera: Cerambycidae) cannot fly since their hindwings are atrophied. This slows down gene flow between local populations. Currently, it is considered that the genus contains four endemic species from the eastern Honshu Is., Japan, M. binodosus, M. furciferus, M. taniguchii and M. fujisanus, that are distributed parapatrically. Sequence analyses of the cytochrome oxidase subunit I gene suggests that lineages of mitochondrial haplotypes split approximately in the same era. However, this result is not consistent with the monophyly of morphological species. The estimated evolutionary rate of the COI gene in other insects suggests that mitochondrial haplotypes of Mesechthistatus differentiated at the end of the Pliocene epoch during the Tertiary era

Relaciones intrafamiliares y expectativas de futuro en adolescentes: una revisión sistemática de la literatura científica de los últimos 10 años

La presente investigación es una revisión sistemática de literatura científica que tuvo como objetivo revisar estudios que guarden relación con las variables relaciones intrafamiliares y expectativas de futuro en adolescentes en los últimos 10 años. Par la realización de la investigación se extrajo artículos de revistas indexadas de referencia internacionales, publicadas en las bases de datos de Scielo y Redalyc, con una antigüedad no mayor a diez años, en idioma español, y que los estudios se refieran a las variables en mención. Se utilizó el método descriptivo. Los artículos escogidos se sintetizaron en una tabla Excel organizando la información, teniendo en cuenta, autor, año, país, idioma, metodología. El estudio arrojó que España lidera las investigaciones sobre las variables en estudio y en Perú un ligero incremento de estudios con ambas variables. Señalando la necesidad de mayores estudios con instrumentos medibles y la validación de escalas para ser aplicadas localmente

A Practice of “Fushizukuri Education”: Focusing on Rhythm Learning at Hiroshima Municipal Hesaka Elementary School

“Fushizukuri Education” is the most successful music education method in Japan, started in 1966 at Furukawa Elementary School in Hida area, Gifu Prefecture. This method was developed by a group of teachers who were not specialized in music. The characteristics of this method are as follows: (1) the curriculum consists of 30 phases, 102 steps; (2) adopting dual approach comprised of performance and music basics; (3) the learners themselves progress the class with minimum intervention by the teacher; (4) special emphasize is placed on hearing; (5) sufficient opportunities for solo singings and remarks are guaranteed for all learners, (6) the teacher’s remarks are minimized, and (7) the learners eventually demonstrate excellent musical and performance ability. This study aims to find how to install “Fushizukuri Education” effectively into current school music curricula in Japan. Both practical and experimental approaches are employed. Children participated in this study were the third graders at Hesaka Elementary School. The four classes were randomly divided into two groups comprised of two classes each. Children in one group learned using conventional staff notation system, whereas children in the other group learned using the “maru-fu” (circle notes) notation system. Rhythm learning activities were organized for both groups based on the “Fushizukuri Education” method. A pretest and a posttest were carried out in July and late September 2017, respectively. Both tests measured each child’s abilities of rhythm reproduction and rhythm reading. In the rhythm reading pretest, both groups were tested with one-line staff materials. In the rhythm reading posttest, the “maru-fu” group was tested with “maru-fu” materials, whereas the staff group was tested with one-line staff materials. Following results were obtained. (1) Both groups have developed abilities of rhythm reproduction and rhythm reading through rhythm learning activities, although the number of activities was not so many. (2) In the pretest, the staff group outperformed the “maru-fu” group on both reproduction task and reading task. (3) It is presumed that the learners have been familiarized with five-line or one-line staff notation system up to the third grade, whereas they might feel novelty in the “maru-fu” notation system. (4) Therefore, the “maru-fu” notation system should be used in the first grade.三村真弓教授退職記念号 Special Number Commemorating the Retirement of Professor Mayumi Mimur

La importancia de las rutinas permanentes en el desarrollo de la autonomía de los niños de 3 años "Aula Rosada" de la I.E.P. "Santa María de Guadalupe", Trujillo en el año 2017

El presente estudio titulado la importancia de las rutinas permanentes en el desarrollo de la autonomía de los niños de 3 años "aula rosada" de la I.E.P. "Santa María de Guadalupe", Trujillo en el año 2017, tuvo como objetivo determinar en qué la importancia de las rutinas permanentes desarrollará significativamente la autonomía de los niños. Para ello, se empleó una muestra de dos salones de la edad de 3 años siendo en aula rosada el grupo experimental (14 niños) y el aula celeste del grupo control (15 niños). Su diseño de investigación fue casi experimental pre test-pos test. Se utilizó, la técnica de la observación, y como instrumento se aplicó una encuesta para el desarrollo de la autonomía. Como resultado relevante, se halló en el grupo control, una mínima diferencia de puntajes en el pre y post test; no obstante, en el grupo experimental se observó una mayor diferencia entre el pre y post test entre 7.57 puntos y 19.57 puntos debido a que en este grupo sea aplicó el programa de rutinas permanentes.Tesi

Search for the field-induced magnetic instability around the upper critical field of superconductivity in H || c in CeCoIn5

We present nuclear spin-lattice relaxation rate (1/T1) at the Co site and ac-susceptibility results in the normal and superconducting (SC) states of CeCoIn5 for H || c near the SC upper critical field Hc2 above 0.1 K. At 4.2 T, 1/T1 rapidly decreases below the SC transition temperature, consistent with the previous reports. Although the field dependence of 1/T1T at 0.1 K shows a peak at 5.2 T above Hc2, the temperature dependence of 1/T1T at 5.2 T is independent of temperature below 0.2 K, showing a Fermi-liquid behavior. In addition, we found no NMR-spectrum broadening by the appearance of internal fields around Hc2 at 0.1 K. We could not detect any field-induced magnetic instability around Hc2 down to 0.1 K although the remarkable non-Fermi-liquid behavior towards Hc2 was observed in various physical quantities.Comment: 6 pages, 3 figure

A new genus and species of thorny lacewing from Upper Cretaceous Kuji amber, northeastern Japan (Neuroptera, Rhachiberothidae)

Kujiberotha teruyukii gen. et sp. n., a remarkable new genus and species of Rhachiberothidae, is described from Upper Cretaceous amber from the Kuji area in northeastern Japan. This discovery represents the first record of this family both from Japan and from East Asia. This fossil taxon has the largest foreleg in the subfamily Paraberothinae found to date and its discovery implies that this group had higher morphological diversity in the Cretaceous than it does now. This finding also stresses the importance of the insect inclusions in Kuji amber, which have not been well explored in spite of their potential abundance
