Gotlandic pottery outside Gotland
Authors: Eriksson Thomas 
Published: January 2020

The article discusses contacts and networks along the eastern coast of Sweden and around the Baltic Sea. The focus is on the decorated pottery c. 0–700 AD. Sweden and Scandinavia had different regional styles of pottery during this period. One of the most distinctive Scandinavian styles is found on Öland and Gotland. This style is distinguished by the elaborate use of stamps and vessels with handles positioned from the rim to the shoulder. Vessels made in this style are found outside the large islands, notably in Svealand, i.e. the lake Mälaren Basin in central Sweden, as well as in northern Sweden. More interesting is the spread and influences in the Dollkeim-Kovrovo culture, in north-eastern Poland, and Oblast Kaliningrad. During the Roman Iron Age, a special type of beaker is found from the Mälar basin to Gotland/Öland and further on in Oblast Kaliningrad. The connection can also be seen in dress ornaments and other artefacts. The regional differences in the pottery decrease during the Vendel Period (c. 550–800 AD). A new style of stamped vessels is spread from the Langobards in northern Italy to England and Scandinavia and marks a new, more uniform material culture. This marks probably a new area of more complex and centralised political units.

AbstrakEfek dari krisis ekonomi global adalah menurunnya aktivitas ekspor dan impor yang mempengaruhi terhadap menurunnya permintaan pembangunan kapal baru. Hal ini mengakibatkan galangan kapal melakukan efisiensi di seluruh aspek untuk tetap bertahan salah satunya dengan mengurangi biaya produksi sebuah kapal. Banyak studi terkait pengurangan berat dan biaya yang telah dilakukan dengan menggunakan metode optimasi. Penulis memilih struktur dek kapal yang terdiri dari pelat dan stiffener sebagai studi kasus. Pada studi ini, penulis mengoptimasi biaya fabrikasi struktur dek kapal yang terdiri dari biaya material dan biaya pengelasan dengan menggunakan hybrid algoritma genetika yang mengkombinasikan algoritma genetika dan metode optimasi lanjut. Algoritma genetika mengoptimasi variabel desain diskrit yang terdiri dan jumlah stiffener dan ukuran stiffener sedangkan metode optimasi lainnya mengoptimalkan variabel desain kontinyu yang terdiri dari jarak stiffener dan ketebalan pelat. Penulis mengambil bagian dari dek kapal tanker menjadi target optimasi yang kemudian dibandingkan hasilnya dengan data awal kapal. Hasil menunjukkan bahwa metode optimasi ini dapat mengurangi biaya fabrikasi dek kapal hingga 25 %. Abstract The impact of the global economic crisis is a decline in import and export activities resulting in a decrease in shipbuilding demand. Shipyard companies do efficiency in all aspects to survive which one of them is reduced production cost of a ship. Many studies for a lightweight and low-cost structure are being done which we also propose to solve the problem with the optimization method. We selected deck structure as a case study which is composed of plates and stiffeners. In this study, we optimized fabrication cost such the material cost and welding cost with a hybrid genetic algorithm (GA) which applied a genetic algorithm and other optimization methods. Genetic algorithm optimized the discrete design variables which are a number of stiffener and type of stiffener and other optimization methods optimized the continuous design variables which are stiffener spacing and plate thickness. We carried out part of deck structure of crude oil tanker, and the optimization results compared with data of existing ship. The result shows that the optimization method can decrease the fabrication cost of deck structure about 25 %.

La configuración del proyecto de vida es un reto de todo ser humano. Los factores que condicionan la construcción del proyecto vital son diversos: escasa madurez, falta de identidad, personalidad conflictiva, entorno sociofamiliar problemático, fracaso escolar, etc. La investigación tiene como objetivo analizar el proceso de configuración de los proyectos de vida en adolescentes en riesgo de exclusión social. Se realizó un estudio de casos múltiples con seis adolescentes con trayectorias de exclusión acogidos al sistema de protección. En el estudio se utilizaron instrumentos y técnicas cualitativas (diario de campo, entrevistas abiertas y grupos de discusión) y cuantitativas (cuestionario). Los resultados muestran que estos menores poseen dificultades para proyectar un futuro al margen de los contextos de exclusión social en los que se han desarrollado. Los proyectos de vida son construidos desde la inadaptación al sistema y sobre una base socioemocional deficiente, ocasionando en los jóvenes la incapacidad de generar pensamientos y conductas asertivas para lograr alcanzar las metas fijadas. Es necesario: a) trabajar con los adolescentes en riesgo de exclusión la adquisición de estrategias socioemocionales, y b) prevenir las conductas intra e interpersonales conflictivas, a través de acciones de atención/apoyo.
The configuration of the life design is a challenge for every human being. The factors that determine the construction of the life design are diverse: lack of maturity, lack of identity, con-flictive personality, problematic social and family environment, school failure, etc. This study attempts to analyse the process of shaping life designs in adolescents at risk of social exclusion. A multi-case study was conducted with six adolescents presenting exclusion trajectories that were within the protection system. In the study, qualitative (semi-structured and diary field inter-views) and quantitative (questionnaire) data retrieval tools and techniques were used, opting for a mixed methodology. The results show that these children have difficulties in projecting a future outside the contexts of social exclusion in which they have developed. Life designs are built from the maladjustment to the system and on a deficient social-emotional basis, making young people unable to generate assertive thoughts and behaviors to achieve the goals set. It is necessary to: a) work with adolescents at risk of exclusion to make them acquire social-emotional strategies, and b) prevent conflicting intra and interpersonal behaviour through care/support actions.

Este artículo da cuenta del proyecto “Propuesta interuniversitaria de formación inicial de maestros en tecnologías digitales”. Para elaborarla, nos planteamos conocer la percepción de estudiantes y de docentes sobre qué necesidades abordar en relación con las tecnologías digitales y la competencia digital metodológica, y qué acciones institucionales son preferentes para desarrollar la competencia digital docente (CDD). En este estudio, utilizamos un diseño de investigación de métodos mixtos. Las técnicas e instrumentos usados han sido el análisis de la documentación disponible, grupos de discusión y cuestionarios. La propuesta va dirigida a las nueve universidades catalanas que imparten la formación de futuros docentes en los grados de Maestro de Educación Infantil y Primaria. Las principales conclusiones apuntan hacia la necesidad de vincular la universidad con la sociedad, así como de favorecer un desarrollo profesional del profesorado universitario y la alfabetización digital de sus estudiantes fomentando el aprendizaje colaborativo y la autoría. También, se destaca la importancia de priorizar la comunicación y la colaboración durante el proceso de enseñanza y aprendizaje usando recursos digitales útiles que lo faciliten. A su vez, se resalta la ética y la ciudadanía digital como una dimensión emergente a considerar en la práctica educativa. Finalmente, se apuntan tres acciones institucionales sobre CDD para contemplar en los planes de estudio universitarios.
This article provides an account of the project "An inter-university proposal for the initial training of teachers in digital technologies". In order to prepare it, we consider the perception of students and teachers on what needs to be addressed with regard to digital technologies and methodological digital competence, and what institutional actions are preferential for the development of teachers’ digital competence (TDC). In this study, we used a mixed-method research design. The techniques and instruments used have been the analysis of available documentation, focus groups and surveys. The proposal is targeted at the nine Catalan Universities that provide training for future teachers in Pre-school and Primary Education Degrees. The main findings point to the need to link the university to the society, as well as to promote a professional development of university teachers and the digital literacy of their students by fostering collaborative learning and authorship. Likewise, it highlights the importance of prioritizing communication and collaboration during the teaching and learning process using useful digital resources that facilitate it. At the same time, ethics and digital citizenship is highlighted as an emerging dimension to be considered in educational practice. Finally, three institutional actions about TDC are pointed out to consider in university curricula.

Published: January 2020

Este trabajo se centra en el fraude en las evaluaciones por parte del alumnado universitario español y su reglamentación por parte de las universidades como dispositivo para combatirlo. A partir del análisis de la literatura y la consulta a un panel de expertos mediante la administración de un cuestionario en dos rondas se identifican los principales comportamientos fraudulentos en las evaluaciones. Posteriormente, a partir de las opiniones de los expertos se determina, por una parte, el nivel de gravedad de cada uno de los comportamientos fraudulentos y, por otra, el tipo de sanciones aplicables según su gravedad. El análisis del grado de concordancia de los expertos en torno a estas cuestiones sugiere que, si bien hay algunos elementos que presentan un consenso significativo, continúan habiendo importantes divergencias en algunos criterios fundamentales a la hora de valorar y sancionar los comportamientos fraudulentos del alumnado en las evaluaciones. Los resultados ofrecidos pueden ser de utilidad para la elaboración y desarrollo de políticas educativas contra la deshonestidad académica basadas en dispositivos normativos
This paper focuses on the fraud in the evaluations perpetrated by the Spanish university students and its regulation by the universities as a device to combat it. From the analysis of the literature and the consultation of a panel of experts through the administration of a questionnaire in two rounds, the main fraudulent behaviours in the evaluations are identified. Subsequently, based on the opinions of the experts, it is determined, on the one hand, the level of seriousness of each of the fraudulent behaviours and, on the other, the type of sanctions applicable according to their severity. The analysis of the degree of concordance of the experts on these issues suggests that, although there are some elements that present a significant consensus, there continue to be important divergences in some fundamental criteria when assessing and punishing the fraudulent behaviour of students in the evaluations The results offered can be useful for the development and implementation of educational policies against academic dishonesty based on normative devices.

Este estudio se centra, en conocer desde el punto de vista de los directivos, el desarrollo del liderazgo pedagógico y la mejora escolar. Para ello se ha contado con la participación de 47 directores y directoras que ejercen en centros públicos y concertados. En el proceso metodológico de corte cualitativo, se ha utilizado la técnica de la entrevista, con la finalidad de conocer cómo se asumen los cambios normativos en cuanto a procesos metodológicos y de evaluación para establecer propuestas de mejora. En la recogida de datos se han manejado las categorías correspondientes a los indicadores aportados por las entrevistas, y para su análisis se ha utilizado el programa estadístico Atlas.Ti versión 6.2. Entre los principales resultados destacamos que gran parte de los directivos mantienen que la metodología más utilizada tras aplicarse la nueva normativa es el trabajo por Proyectos. Mientras que en la categoría evaluación el cambio más valorado ha sido la introducción de una evaluación más cualitativa a través de Rúbricas. Con respecto a los posibles mejoras escolares los directivos plantean la necesidad de llevar a cabo en cada centro un proyecto de acción colectivo al servicio de una educación para todos. En términos generales, los resultados del estudio confirman que la opinión de los directivos sobre el liderazgo pedagógico y mejora escolar viene determinada por la normativa, limitando su estructura de trabajo.
The aim of this study was to determine, from the managerial perspective, the development of pedagogical leadership and school improvement, with the participation of 47 principals from public and charter schools. The qualitative methodology was based on interviews, which were designed to reveal how the changes in regulations were assumed in terms of methodological and evaluation processes, in order to establish suggestions for improvement. To gather the data, we used the categories that corresponded to the indicators provided by the interviews, and the statistical software Atlas v.6.2 was used for the data analysis. Among the main results, a large part of the participants stated that the
most used methodology after implementing the new regulations was “project assignment”; on the other hand, in the evaluation category, the most valued change was the introduction of a more qualitative evaluation through the use of rubrics. With respect to possible school improvements, the participants highlighted the need to carry out in each centre a community action project for an education for everyone. In general terms, the results of the study confirm that the opinion of the participants about pedagogical leadership and school improvement is determined by the regulations, which limit their work structure.
Las altas capacidades en el sistema educativo español: reflexiones sobre el concepto y la identificación
Authors: Tourón Javier 
Published: January 2020

El presente trabajo recoge una apretada síntesis de algunos de los problemas conceptuales que están directamente relacionados con el desarrollo de la atención a los estudiantes con alta capacidad en el sistema educativo español, preferentemente no universitario. Así, parece esencial centrarse en el enfoque teórico de los modelos preeminentes en la literatura científica más relevante que permitan arribar a una mínima conceptualización operativa de los conceptos de capacidad y talento. Por otra parte, se analizan los problemas derivados de la identificación y su evidente déficit en las escuelas públicas y privadas. Algunas consideraciones a modelos relevantes de identificación basados en las medidas “out of level” son objeto de atención particular por su importancia metodológica y práctica, y por haber sido implantado por el autor durante años en España.
This paper gathers a tight synthesis of some of the conceptual problems that are directly related with the development of service to gifted students in the Spanish education system, preferably non-university. Thus, it seems essential to focus on the theoretical approach of the preeminent models in the most relevant scientific literature that allow us to get a minimum operational conceptualization of the concepts of ability and talent. On the other hand, the problems derived from identification and its evident deficit in public and private schools are analyzed. Some considerations to relevant identification models based on the “out of level” measures are given particular attention for their methodological and practical importance and for having been implemented by the author for years in Spain.

DIVERSITY IN THE LANGUAGE CLASSROOM: RAISING AWARENESS
Access to education should be universal in all cases; however, bureaucracy and policy conventions sometimes divert unconsciously from this objective. Although educational institutions have been rowing in the right direction in the last decade, still a lot remains to be done to make education accessible to everyone.
Accessibility to education in most cases goes hand in hand with new technologies and the concept of e-learning accessibility (Phipps &amp; Kelly, 2006), since information and computer technologies (ICT) are present in all levels of the educational sphere. To achieve this, the European Union and governments worldwide have advanced in the publication of directives and requirements that advocate for equal access to education technology, for example access to websites and applications for the public sector. This means that education can be adapted to students’ needs according to their functionality (Batanero, et al., 2014).
The current issue includes contributions that delve into the educational sector with practices and pedagogical accommodations to students’ needs. The issue, structured in two differentiating sections includes four full articles in the main section and two book reviews.

ABSTRACT
As labour markets continue to change rapidly, the learning environments continue to be unchallenged in the provision of new professionals across the world. This change has compelled the need for students to attain communicative competences in non-linguistic institutions of higher education. In order to address this issue, we propose a novel approach to communicative competences integration into the curriculum development of a specialised foreign language course. For this purpose, we combine students’ needs analysis with a personalised English for specific purposes (ESP) course design that motivates them to learn more about technical and professional environments through a skill-based routing. Additionally, we provide a scale for measuring training outcomes as well as suggest first results from the piloting phase of the teaching experience. The findings of the study highlight usefulness of the customised competence training experience.
Operational Landscapes: Hinterlands of the Capitalocene
Authors: Brenner Neil , Katsikis Nikos 
Published: January 2020

AbstractIn recent decades, the field of urban studies has neglected the question of the hinterland: the city's complex, changing relations to the diverse noncity landscapes that support urban life. Neil Brenner and Nikos Katsikis of the Urban Theory Lab at the Harvard Graduate School of Design argue that this ‘hinterland question’ remains essential, but must also be radically reimagined under contemporary conditions.

Published: January 2020

AbstractAmbipolar transport characteristics of thin film transistors fabricated from nontoxic white light emitting quantum dot complexes (QDCs) are herein reported to exhibit efficient carrier mobilities. The QDCs are synthesized by forming bluish green emitting zinc quinolate complex on the surface of orange emitting Mn2+‐doped ZnS quantum dots (Qdots) using 8‐hydroxyquinoline 5‐sulfonic acid as the chelating ligand. The device exhibits efficient ambipolar transport characteristics with high ION/IOFF ratio of 104 and electron mobility and hole mobility of 2.95 × 10−02 and 1.06 × 10−02 cm2 V−1 s−1, respectively. The subthreshold slope of Qdot complex–integrated thin film transistor increases from that of Mn2+‐doped ZnS Qdot–integrated thin film transistor from 0.35 to 0.79 V dec−1 in p‐field effect transistor (FET) and from 0.59 to 0.97 V dec−1 in n‐FET operations, which annotates an increase in trap state density due to surface complexation of the Qdot. These results suggest that white light emitting QDC can be used as an efficient transport as well as an emissive material, which open up new paradigm for advanced optoelectronic applications.
Oxalyl‐CoA Decarboxylase katalysiert die nukleophile ein‐Kohlenstoff‐Verlängerung von Aldehyden zu chiralen α‐Hydroxysäuren

Published: January 2020

AbstractDie Synthese komplexer Moleküle aus erneuerbaren Kohlenstoffbausteinen ist ein zentrales Ziel einer nachhaltigen Wirtschaft. Hier untersuchten wir das biokatalytische Potential Thiamindiphosphat (ThDP)‐abhängiger Oxalyl‐CoA Decarboxylasen (OXC)/2‐Hydroxyacyl‐CoA Lyasen (HACL). Diese Enzyme katalysieren den Abbau von Acyl‐CoA‐Thioestern unter Bildung des C1‐Moleküls Formyl‐CoA. In der OXC/HACL Superfamilie kommen aber auch unspezifische Enzymvarianten vor, die C1‐Bausteine mit verschiedenen Aldehyden kondensieren und so 2‐Hydroxyacyl‐CoA‐Thioester bilden. Eine verbesserte OXC‐Variante mit zwei neu beschriebenen Enzymen – einer spezifischen Oxalyl‐CoA Synthetase und einer 2‐Hydroxyacyl‐CoA Thioesterase — wurde zu einer Kaskade kombiniert, die die Umsetzung von Oxalat und aromatischen Aldehyden zu (S)‐α‐Hydroxysäuren mit einem Enantiomerenüberschuss (ee) bis zu 99 % ermöglicht. Unsere Studie zeigt das Potential ThDP‐katalysierter C1‐Erweiterungsreaktionen in der nachhaltigen Synthese chiraler Bausteine.
