Abstract
—The minerals of the Maslyanino iron meteorite and their trace-element composition are described in detail for the first time, and the meteorite classification is substantiated. The meteorite is a fine-structural octahedrite. Its metallic matrix consists of kamacite, taenite, and schreibersite. Large troilite segregations are associated with silicate inclusions; in addition, rare minerals altaite and dobreelite are found. The silicate inclusions contain olivine, orthopyroxene, clinopyroxene, plagioclase, apatite, merrillite, chromite, and graphite. A detailed trace-element analysis of the metallic matrix permits the Maslyanino meteorite to be assigned to the narrow Pitts subgroup of the IAB group. It is also similar to meteorites of the Udei Station subgroup. Both subgroups include meteorites with silicate inclusions and are intermediate between the sLL (low Au and Ni contents) and sLM (low Au and medium Ni contents) subgroups. According to the metal-lographic data, the cooling rate of the Maslyanino meteorite is 30–60 ºC/Myr. The data obtained are consistent with the formation of the meteoritic material under impact of a parent asteroid resulting in the removal of its outer chondrite–winonaite shell. Subsequent weaker impacts led to the formation of IAB group meteorites (including meteorites with silicate inclusions) and winonaites from the asteroid remnant.

Published: July 2019

In this study, we investigated the expression of the pattern concept in primary education. For this purpose, we chose the concept of rhythm as a means of repeating found in different contexts. In Music and Arts, rhythm is first a way to make compositions. In the case of learning Math, rhythm can aid in comprehending various structures. We used action research in this article – our study contained some trials of learning to understand composition and structures by completing some origami applique tasks; pupils from the 2nd grade were our study participants. The study was held during the following 3 stages: the investigation of simple repeating, the exploration of rhythmical directional changes, and the examination of rhythmical size changes. Fourteen participants took part in the study. The pupils were asked to make some compositions of origami applique based on certain rules set for them. The participants had to also use their experience acquired in the aforementioned tasks for further tasks, which required them to create their own patterns. They had to realize the basic underlying structures for completing such tasks.The data were gathered by collecting paper crafts made by students and by audiotaping the discussions with these children. After employing content analysis, for the sake of visual illustrations of the results, the main features of various task performance were depicted using some typical real examples from the paper crafts of the students.The results showed that 2nd graders were able to replicate a simple rhythm without making mistakes. When creating line-type ornaments, they concentrated on one possible feature to make the rhythm, often mostly ignoring such possibilities as repetitions in number, direction, and size. After gaining some new knowledge during the process of origami applique activities designed to teach the possibilities in changing direction and size, the pupils were eager to apply various structures elsewhere. The children were fast to realize the importance of tidy composition, to solve the arising difficulties, and to generalize the experience in some other contexts.
University Mergers in Lithuania: A Media Discourse Analysis
Authors: Bružienė Rūta 
Published: July 2019

University mergers could be perceived as a political process – at least during the first stages of the process, which contain discussions about common visions, goals, and measures. Therefore, a university merger could be analyzed using the methods of political discourse analysis, which allows to understand how public discourses about merging universities have been constructed, legitimized, and institutionalized.It is important to understand the process of university mergers as a political phenomenon that is constructed by stakeholders using public discourses. Public discourses, reflected in the media, form the society’s opinion about a university merger and have influence on policy decisions and the implementation process of these decisions. In this context, the purpose of this article is to analyze the written content related to university merger issues published in online media during the course of three years (2016–2018). Quantitative content analysis was made using software Hamlet II 3.0. Some trends of public discourse related to university mergers have been detected. It is noticed that a university merger is primarily related to the improvement of higher education quality and the needs of business and the state in public discourse. However, the declared political goal of seeking competitiveness and quality of research is not developed and reflected in the media. This shows a certain fragmentation of ideas in the process of merging universities, because the society, the academic community, and the government agree (as reflected in the documents (2017)) that only a unity of research and studies could assure the highest quality university education and international recognition.Also, differences between business and university mergers have been noticed. More rational arguments are used to justify business mergers than social and cultural ones (Vaara, Tienari 2002) when compared to university mergers. Stakeholders usually use a combination of social and rational arguments in public discourse to justify university mergers.

Objetivo: analisar a morbimortalidade decorrente da violência e maus tratos contra idosos no Rio Grande do Norte (RN) (Brasil), no período de 2000 a 2010, e analisar sua distribuição espacial.Metodologia: estudo ecológico, utilizando o índice de Moran Local-lisa, com valor de p < 0,05, considerado para significância estatística. No estudo da morbimortalidade em idosos por agressões no RN, separada por sexo, os dados foram coletados a partir do datasus. A população estudada foi o grupo dos idosos residentes no estado do RN que faleceram ou foram internados em função de violência ou maus tratos no período analisado.Resultados: a mortalidade e morbidade por agressões no RN da população idosa entre 2000 e 2010 apontam maior incidência no sexo masculino (90 %) do que no feminino (85 %). Na análise geoespacial da mortalidade, destacou-se que no sexo feminino há maior concentração de casos nas áreas leste e central do estado e masculino nas regiões oeste e Agreste. Os dados sobre morbidade apontam concentração nas regiões leste e Agreste para as mulheres e para os homens nas regiões leste, oeste e central. Não houve significância estatística, provavelmente em função de número reduzido de ocorrências e isso pode indicar subnotificações.Conclusão: a identificação das áreas desfavoráveis aponta à necessidade de averiguar a existência de casos não notificados de violência contra idosos a fim de levantar dados que possam embasar a construção de estratégias conjuntas de enfrentamento a essas violações envolvendo saúde, assistência social e sociedade civil.

Authors: Díaz Monsalve Luz Ever 
Published: July 2019

Objetivo: describir los componentes integradores de una didáctica pertinente para la enseñanza de la promoción de la salud mediante el análisis reflexivo de una experiencia educativa iniciada en el año 2010 con docentes de una institución educativa, para la promoción de la salud sexual de los escolares.Método: estudio cualitativo tipo sistematización; participaron 19 docentes con entrevistas y grupos de discusión. La información se analizó mediante codificación abierta, axial y construcción de categorías emergentes. Resultados: la educación para la salud (EpS) es un proceso de enseñanza que contiene los elementos de la didáctica tradicional, solo que en esta se conceptúan e interactúan en forma diferente; por ejemplo, en vez de enseñantes-aprendices, existen sujetos (de cuidado y orientadores), quienes tienen biografía y saberes dignos de valorar. Las intenciones se deben dialogar y negociar, el saber debe corresponder al contexto sociocultural, no obstante, en cualquier proceso de EpS, empoderamiento, re-conocimiento y re-significación de sí mismo, del otro y del entorno son comunes. Las técnicas y actividades didácticas deben motivar la reflexión y socialización. Conclusión: la EpS es un proceso de enseñanza en el cual los elementos didácticos son sujetos porque tienen un saber valioso, hay intenciones que deben dialogarse y negociarse, y un saber que convoca y que debe involucrar potenciación del empoderamiento y la promoción de actitudes y prácticas saludables. Todo esto se refleja en las técnicas y actividades didácticas.

The level of work motivation is based on two aspects which are indicators, namely motivator factors and health or maintenance factors. The motivator factor is a factor or situation that can encourage achievement and intrinsic in nature that comes from within the da'i itself. This motivator factor relates to opportunities for achievement, opportunities to gain recognition, advances, opportunities in the work itself, personal improvement or development and opportunities to obtain responsibility. While hygiene / sanitation factors are extrinsic factors which are derived from outside the preacher, but also determine the behavior of preachers in carrying out their work and related to the environment in which the work is carried out. Hygiene factors will provide satisfaction (satisfies) if these factors are met, on the contrary if it is not fulfilled it will cause dissatisfaction (dissatisfaction) which will cause demands for the da'i.

Authors: Nasri Khairul 
Published: July 2019

Ditemukan bahwa majelis hakim PTA Padang menetapkan hadhanah bagi anak yang belum mumayyiz beralih kepada suami bukan kepada pihak istri. Majelis Hakim PTA Padang menerapkan asas contra legem terhadap Pasal 105 huruf (a) Kompilasi Hukum Islam (KHI). Pasal 105 huruf (a) KHI telah menggaris bawahi dalam hal terjadinya perceraian “pemeliharaan anak yang belum mumayyiz atau belum berumur 12 tahun adalah hak ibunya”. Pemindahan hadhanah dari pihak istri ke pihak suami bagi anak yang belum mumayyiz merupakan bukti kongkret penerapan asas contra legem terhadap Pasal 105 huruf (a) KHI, dapat dipahami bahwa contra legem ialah wewenang hakim untuk mengesampingkan penerapan pasal dalam undang-undang atau bertentangan dengan undang-undang, berbarengan dengan itu hakim melakukan penemuan hukum (rechtvinding), dapat dipahami Majelis Hakim PTA Padang dalam pertimbangan hukum melakukan rechtvinding dengan menggunakan metode interpretasi sistematis (logis) yaitu menafsirkan peraturan perundang-undangan dengan menghubungkannya dengan undang-undang lain.
