AbstractThis paper presents a Geographic Information System catalogue of the submarine landslides of the Spanish continental margin and describes the problems associated with harmonizing the catalogue with its onshore homologue. The data model structure is described to explain how to apply the rules and specifications following the Infrastructure for Spatial Information in Europe (INSPIRE). Because of the singularities of the marine environment compared with those of land, integrating the submarine landslide catalogues into INSPIRE specifications requires the following procedures: (1) simplification of the list of values of state of activity into three categories: active, dormant and relict; and (2) inclusion of debris avalanches and turbidites as new typologies of landslides. This paper discusses the problems associated with harmonizing different data types and units from different sources, such as the thickness (metres and seismic two travel time) or the age of the event, and a numeric code for the geological timescale is proposed to harmonize these data. We establish whether an item is required based on the reliability of the landslide event, which is categorized by three levels (high–middle–low) depending on the precision of the data source, methodology used and quality of the publication where the data are obtained.

This study assesses the quality of Chinese outbound FDI data. In our case study of the Netherlands, we checked the data quality of the often-used Orbis/Amadeus database and its data source, the Dutch Chamber of Commerce (Kamer van Koophandel, KVK), which has one of the oldest and, arguably, one of the better databases within Europe. We analysed Chinese investments in the Netherlands and show that six adjustments are necessary to clean up the data. We also show that not making these adjustments can significantly impact the outcome of research. The cleaned-up data show that sampled Chinese firms are young, small, and private.

In recent years, life quality of the urban areas is a growing interest of civil engineering. Environmental quality is essential to display the position of sustainable development and asserts the corresponding countermeasures to the protection of environment. Urban environmental quality involves multidisciplinary parameters and difficulties to be analyzed. The problem is not only complex but also involves many uncertainties, and decision-making on these issues is a challenging problem which contains many parameters and alternatives inherently. Multicriteria decision analysis (MCDA) is a very prepotent technique to solve that sort of problems, and it guides the users confidence by synthesizing that information. Environmental concerns frequently contain spatial information. Spatial multicriteria decision analysis (SMCDA) that includes Geographic Information System (GIS) is efficient to tackle that type of problems. This study has employed some geographic and urbanization parameters to assess the environmental urbanization quality used by those methods. The study area has been described in five categories: very favorable, favorable, moderate, unfavorable, and very unfavorable. The results are momentous to see the current situation, and they could help to mitigate the related concerns. The study proves that the SMCDA descriptions match the environmental quality perception in the city.

AbstractThe western North Atlantic passive margin is considered relatively stable, with few slope instabilities recognized during the Holocene. However, new multibeam bathymetry mapping and sediment core acquisition off eastern Canada indicate that previously unidentified, large, submarine landslide events occurred during the Late Holocene, between 4 and 1.5 ka. The recognition of these new gravitational events, in addition to the well-known C.E. 1929 Grand Banks earthquake-induced landslide, indicates that approximately one large landslide event per 1000 years has occurred offshore eastern Canada within the past 4000 years, a much shorter recurrence interval than hitherto reported. This Late Holocene recurrence rate is also similar to active margins around the world and is likely due to the under-consolidation and resultant instability of Scotian Slope sediments attributable to high glacial sedimentation rates. The discovery of these new Late Holocene landslides was made possible through detailed examination of cores recovered from the lower slope. These results demonstrate that submarine landslide hazard has been underestimated on the western North Atlantic margin—home to significant submarine infrastructure and proximal to a large coastal population.

Common Architecture

In this paper, we present a declarative domain-specific language (DSL) for the development of Geographic Information Systems (GIS). GIS applications manage information with a spatial component, usually in the form of points, lines, polygons, or variants of these basic data types, in domains where the spatial information plays a central role. They provide the user with different functionalities on different application domains, but they are usually developed according to a common architecture and using a common set of technologies. Hence, they share a significant number of elements that make some aspects of their development quite repetitive. Our DSL allows developers to specify the entities, geographic layers, and maps of the applications using a declarative language. Then, the specification is transformed into a working GIS application. We present the language, its implementation, and a case study on two sample projects that allowed us to evaluate the resulting software, paying special attention to the savings in the development effort.

This paper proposes a framework for evaluation of the sources of uncertainty that can disrupt the flood emergency response process. During the flood response, flood emergency managers usually choose between several decision options under limited available lead-time, but they are often compelled with different sources of uncertainty. These sources can significantly affect the quality of decisions related to adequate response and rapid recovery of the affected system. The proposed framework considers efficient identification, integration, and quantification of system uncertainties related to the flood risk. Uncertainty analysis is performed from a decision-maker’s perspective and focused on the time period near and during the flood event. The major scope of proposed framework is to recognize and characterize sources of uncertainty which can potentially appear within the behavior of the observed system. Using a Bayesian network approach, a model is developed capable for quantification of different sources uncertainty in respect to their particular type. The proposed approach is validated on the Sava River case study, in the area of the city of Slavonski Brod, following the destructive 2014 flood event. The results indicate that, despite improvements of structural measures, the weir failure can still cause flooding of the approximately 1 km2 of otherwise safe area, resulting in the increased flood risk.

Abstract  Lurik Kembangan is a traditional art product of Yogyakarta. Lurik Kembangan which still survive until now made by Non-Machine Weaving Machine. The more days pass, the variety of lurik becoming more diverse and creating more various products from fabric lurik. However, business competition is getting worse because there is only a few young people who willing to work as craftsmen and the impact of industrialization in Yogyakarta resulting the craftsmen’s income decreases. Qualitative research with case study approach aims to find out the strategies and challenges of lurik craftsmen in facing strait industry competition in Yogyakarta. Validity of data obtained by triangulation of data source. The technique of data analysis is done by integrating observation data at the production place of lurik group Maju Mandiri, Interview with craftsmen, Chairman of Maju Mandiri luric group, and documentation from various sources to support information about Lurik Kembangan craftsmenship. The theory used is Karl Marx's Theory of Capitalism and Theory of Glocalization from Robertson. The results showed that the strategy of the artisans of Lurik Kembangan in facing business competition is to create product innovation; maintaining the quality of traditional lurik; and expand the scope of marketing. The challenge of the craftsmen is to maintain the Lurik Kembangan increasingly heavy because the youth choose to work in factories or other sectors; competition in the middle of Yogyakarta industrialization makes the marketing of weaving lurik become increasingly narrow; the impact of the industrialization created the class of capital owners and craftsmen.Keywords: Industry, Lurik, Strategy, Challenge

The quality of education is largely determined by good school management by supervisors for a better quality of learning, not least in Vocational High Schools. This type of research is qualitative with a case study research design. The main target of this research is supervisors of vocational schools in Padang city. This research is limited to describing qualitatively the supervision process and identifying the constraints that occur in supervision. The data source of this research is from key informants, purposively. Data collection techniques with interview and observation techniques. Data analysis by coding, linking and, interpreting themes. The results of the research are the low professionalism of school supervisors and the low appreciation of the school supervisor profession. The conclusion is that the constraints were basically the result of improper recruitment patterns and were exacerbated by weak control mechanisms.

Research Questions

The widespread proliferation of different types of volunteered geographic information (VGI) is noteworthy as is its potential application to urban studies. However, questions of data quality still remain. In some parts of the Middle East, gated communities have proliferated rapidly, but relatively little is known about their extent or spatial distribution. This case study of gated communities in the state of Bahrain assesses the quality of Wikimapia, a form of VGI, in accurately identifying elements of urban structure (e.g., gated communities) in an urban context from the Global South. Wikimapia demonstrated high levels of positional accuracy and relatively high levels of attribute accuracy. Identifying the locations of gated communities provides a foundation from which other research questions about segregated housing, fragmentation, and socioeconomic polarization can be addressed. These results highlight Wikimapia's potential as a data source for urban research, particularly in data-poor and non-Western/Northern contexts.
