O Híbrido de Timor (HT) 'CIFC 4106' é um anortoploide (alotriploide, 3x=33, 2C=2,10 pg), semi-estéril, oriundo do cruzamento natural entre Coffea arabica (4x=44, 2C=2,62 pg) e Coffea canephora (2x=22, 2C=1,41 pg). Acredita-se que o 'CIFC 4106' é primeira planta de HT encontrada em 1927, numa plantação de C. arabica 'Typica' situada no Timor Leste. Estudos citogenéticos em Coffea têm possibilitado entender a história evolutiva e inferir as contribuições dos genomas parentais na formação de alopoliploides, como C. arabica. Nesse sentido, o conteúdo de DNA cromossômico; mensurado pela combinação da citogenética, citometria de fluxo e de imagem; gerou dados relevantes acerca da origem de C. arabica, um alotetraploide verdadeiro. O presente trabalho objetivou quantificar o conteúdo de DNA nuclear, caracterizar o cariótipo e mensurar o conteúdo de DNA cromossômico do HT e dos seus ancestrais: C. canephora, C. eugenioides e C. arabica. O valor 2C médio nuclear e o número cromossômico variou entre os quatro Coffea: C. canephora (2x=22, 2C=1,41 pg), C. eugenioides (2x=22, 2C=1,38 pg), HT (3x=33, 2C=2,10 pg) e C. arabica (4x=44, 2C=2,62 pg). Portanto, uma série euploide foi confirmada, destacando o conteúdo de DNA do HT equivalente a soma dos valores 1C dos seus progenitores. A caracterização do cariograma mostrou a predominância de cromossomos metacêntricos e submetacêntricos, com exceção apenas de um par acrocêntrico (22) em C. arabica. Distribuindo os valores médios 2C nuclear pelos valores médios de densidade óptica integrada; obtidos por meio da citometria de imagem; o conteúdo de DNA de cada cromossomo dos quatro Coffea foi mensurado. O valor 1C cromossômico de C. canephora oscilou de 0,090 (cromossomo 1) a 0,050 pg (11), C. eugenioides de 0,095 (cromossomo 1) a 0,044 pg (11), C. arabica de 0,090 (cromossomo 1) a 0,030 pg (22), e HT de 0,104 (cromossomo 1) a 0,026 pg (33). Os dados qualitativos (classes cromossômicas) e quantitativos (valor 1C) dos Coffea foram comparados, evidenciando a contribuição das três espécies de Coffea na origem do alotriploide HT.

The Interdisciplinary Nucleus of Open and Accessible Educational Resources (OER Nucleus) of the University of the Republic (UdelaR) in Uruguay, integrates the open practice of research groups from different fields combined with the participation of civil society organizations, educational institutions and governmental sector. The adoption of Open Education strategies, and in particular OER adoption, requires actions that contribute to change educational practices, as well as the development of infrastructures that support OER's life cycle. One of the OER Nucleus research lines integrates information and communication technologies (ICT) with teacher training, towards an improvement in the use and collaborative creation of Open and Accessible Educational Resources and Open Repositories. This paper presents preliminary results of the actions carried out in this line, providing substantive evidence for the development of a sustainable OER Repository and strategies for OER adoption at the university. The convergence between Open Access and OER repositories is analyzed, as well as the requirements for adapting institutional repositories for the implementation of OER collections. Finally, future strategies for the adoption are presented, based on the development of Open Practices.

Road surface monitoring is a key factor to providing smooth and safe road infrastructure to road users. The key to road surface condition monitoring is to detect road surface anomalies, such as potholes, cracks, and bumps, which affect driving comfort and on-road safety. Road surface anomaly detection is a widely studied problem. Recently, smartphone-based sensing has become increasingly popular with the increased amount of available embedded smartphone sensors. Using smartphones to detect road surface anomalies could change the way government agencies monitor and plan for road maintenance. However, current smartphone sensors operate at a low frequency, and undersampled sensor signals cause low detection accuracy. In this study, current approaches for using smartphones for road surface anomaly detection are reviewed and compared. In addition, further opportunities for research using smartphones in road surface anomaly detection are highlighted. ; Sattar, S., Li, S., & Chapman, M. (2018).

In this article we present an ethnomethodological study of a controversial case of 'friendly fire' from the Iraq War in which leaked video footage, war on video, acquired particular significance. We examine testimony given during a United States Air Force (USAF) investigation of the incident alongside transcribed excerpts from the video to make visible the methods employed by the investigators to assess the propriety of the actions of the pilots involved. With a focus on the way in which the USAF investigators pursued their own analysis of language-in-use in their discussions with the pilots about what had been captured on the video, we turn attention to the background expectancies that analytical work was grounded in. These 'vernacular' forms of video analysis and the expectancies which inform them constitute, we suggest, an inquiry into military culture from within that culture. As such, attending to them provides insights into that culture. ; + Sprache: eng

The phenomenon of abandonment is widespread all over the world. All the urban realities, even the most excellent from the point of view of the administration of the territory, present the characteristics of the dismission. Abandonment can involve an isolated building, a part of the city or an entire urban reality, a village or a network of villages. It is a complex phenomenon in constant change that depends on geographical, social and political aspects of a place. In the case of Italian territory, the phenomenon of abandon affects above all the medieval villages diffused on the entire peninsula, not far from the artistic, cultural an architectural heritage, valued and celebrated all over the world for its beauty. The topic of this work are the sleeping beauties (A. Mocciola, 2014), small forgotten towns, small fragments of history and daily life lost in the silence of absence, distant from the institution, hidden from the network of navigators, unreachable mobile, ignored by Wi-Fi. The abandoned Italy is a tourist map read backwards.

Dieses essential will die politische Logik des bedingungslosen Grundeinkommens bzw. Bürgergeldes offenlegen. Daneben erörtert es Zwecke und Wirkungsmöglichkeiten des Bürgergeldes, die in der öffentlichen Diskussion bisher nicht aufgegriffen wurden. Aus beidem ergeben sich höchst brisante politische Schlussfolgerungen. Demgegenüber steckt die öffentlich geführte Debatte über das bedingungslose Grundeinkommen in einer Sackgasse. Dort stehen zumeist Fragen zur Höhe und technischen Ausgestaltung des Grundeinkommens sowie ideologische und ideengeschichtliche Einordnungen im Vordergrund. Die Fragen, ob, wann, wo und in welchem Verfahren ein vollständiges Bürgergeldsystem politisch realisiert werden könnte, spielt dagegen bisher kaum eine Rolle. Diese Fragen gehören aber nicht ans Ende, sie gehören ganz an den Anfang der Debatte. Insofern soll dieses essential dazu beitragen, die Grundeinkommensdebatte vom Kopf auf die Füße zu stellen. Der Inhalt Bedingungsloses Grundeinkommen oder Bürgergeld?

Geospatial information plays an important role in environmental modelling, resource management, business operations, and government policy. However, very little or no commonality between formats of various geospatial data has led to difficulties in utilizing the available geospatial information. These disparate data sources must be aggregated before further extraction and analysis may be performed. The objective of this paper is to develop a framework called PlaniSphere, which aggregates various geospatial datasets, synthesizes raw data, and allows for third party customizations of the software. PlaniSphere uses NASA World Wind to access remote data and map servers using Web Map Service (WMS) as the underlying protocol that supports service-oriented architecture (SOA). The results show that PlaniSphere can aggregate and parses files that reside in local storage and conforms to the following formats: GeoTIFF, ESRI shape files, and KML. Spatial data retrieved using WMS from the Internet can create geospatial data sets (map data) from multiple sources, regardless of who the data providers are. The plug-in function of this framework can be expanded for wider uses, such as aggregating and fusing geospatial data from different data sources, by providing customizations to serve future uses, which the capacity of the commercial ESRI ArcGIS software is limited to add libraries and tools due to its closed-source architectures and proprietary data structures. Analysis and increasing availability of geo-referenced data may provide an effective way to manage spatial information by using large-scale storage, multidimensional data management, and Online Analytical Processing (OLAP) capabilities in one system. ; Miu, M., Zhang, X., M.

Abstract

Geographic Information Systems (GIS) enable the integration, mapping, and analysis of data across numerous domains. It has been estimated that 80 per cent of all data collected by governments and businesses contain geographic references, and the news media are no exception. We will explain how we conceptualize news items as spatial data points and illustrate how GIS can be used to manage and analyze them using a sample of geographic references from local news items published in the Toronto Star newspaper. The analysis makes use of cartographic mapping for visual analysis of local news distribution and geospatial tools for quantitative–statistical analysis of emerging patterns. The objective of this paper is to illustrate how computer-based mapping tools can be used to analyze the geographic distribution of news in order to identify concentrations and gaps in local news coverage within a given area and thus better understand issues and trends in local news reporting.

Die 321 Soldaten, die an der nur 22 Stunden währenden »Meuterei« beteiligt gewesen sind - nun stehen sie vor Gericht. Und auch wenn kein Schuss gefallen ist, niemand ums Leben gekommen ist und die Regierung nicht gestürzt wurde, so hat die Wirtschaft doch erwartungsgemäß Blessuren davon getragen.
