‘Als je onderaan staat dan kun je stijgen’. Beleefde ongelijkheid onder leerlingen in het voortgezetonderwijs
Authors: van den Bulk Lenie , van Eijk Gwen
Published: June 2016

Recent publications on inequality in the Netherlands mostly describe objectively measured dimensions of inequality, but we know little about the subjective dimension: how do people experience inequality? In this article we examine how students in secondary school perceive status inequality, whether they construct a social hierarchy, and how they relate inequality to their own position. The article is based on qualitative research among 177 students (15-17 years old) enrolled in vmbo, havo and vwo. Students were asked to make a visual representation of their perception of society based on 23 photos of social situations and to indicate their own position in society. Sixty percent of the students construct the photo’s hierarchically, which can be interpreted as a reflection of perceived status inequality. The meritocratic ideal seems to justify status inequality. We also find differences in how students of different educational levels see their own social position. Furthermore, we describe how students find ways to neutralize implicit value judgements related to status inequality. In the discussion we elaborate the possible consequences of experienced inequality in general and for students in particular, and the role of our education system in the construction and reproduction of status inequality.

Published: June 2016

Abstract. Both primary biological aerosol particles (PBAPs) and oxidation products of biogenic volatile organic compounds (BVOCs) contribute significantly to organic aerosols (OAs) in forested regions. However, little is known about their relative importance in diurnal timescales. Here, we report biomarkers of PBAP and secondary organic aerosols (SOAs) for their diurnal variability in a temperate coniferous forest in Wakayama, Japan. Tracers of fungal spores, trehalose, arabitol and mannitol, showed significantly higher levels in nighttime than daytime (p < 0.05), resulting from the nocturnal sporulation under near-saturated relative humidity. On the contrary, BVOC oxidation products showed higher levels in daytime than nighttime, indicating substantial photochemical SOA formation. Using tracer-based methods, we estimated that fungal spores account for 45 % of organic carbon (OC) in nighttime and 22 % in daytime, whereas BVOC oxidation products account for 15 and 19 %, respectively. To our knowledge, we present for the first time highly time-resolved results that fungal spores overwhelmed BVOC oxidation products in contributing to OA especially in nighttime. This study emphasizes the importance of both PBAPs and SOAs in forming forest organic aerosols.

Published: June 2016

Abstract. Large-eddy simulations (LES) of a multi-week period during the HD(CP)2 (High-Definition Clouds and Precipitation for advancing Climate Prediction) Observational Prototype Experiment (HOPE) conducted in Germany are evaluated with respect to mean boundary layer quantities and turbulence statistics. Two LES models are used in a semi-idealized setup through forcing with mescoscale model output to account for the synoptic-scale conditions. Evaluation is performed based on the HOPE observations. The mean boundary layer characteristics like the boundary layer depth are in a principal agreement with observations. Simulating shallow-cumulus layers in agreement with the measurements poses a challenge for both LES models. Variance profiles agree satisfactorily with lidar measurements. The results depend on how the forcing data stemming from mesoscale model output is constructed. The mean boundary layer characteristics become less sensitive if the averaging domain for the forcing is large enough to filter out mesoscale fluctuations.
Growth of the coccolithophore Emiliania huxleyi in light- and nutrient-limited reactors: relevance for the BIOSOPE deep ecological niche of coccolithophoresbatch
Authors: Perrin L. , Probert I. , Langer G. , Aloisi G.
Published: June 2016

Abstract. Coccolithophores are unicellular, calcifying marine algae that play an important role in the oceanic carbon cycle via their cellular processes of photosynthesis (a CO2 sink) and calcification (a CO2 source). Alongside the well-known, shallow-water coccolithophore blooms visible from satellites, deep niches of coccolithophores are a poorly known but potentially important coccolithophore ecosystem. We investigated the conditions that regulate the development of a deep coccolithophore niche (150–200 m depth) along the BIOSOPE transect in the South Pacific oceanic gyre. We carried out batch culture experiments with a coccolithophore strain isolated from the BIOSOPE transect, reproducing the in situ conditions of light- and nutrient- (nitrate and phosphate) limitation. By simulating coccolithophore physiology using an internal stores (Droop) physiological model, we were able to constrain fundamental physiological parameters for this BIOSOPE coccolithophore strain. We show that simple batch experiments, in conjunction with physiological modelling, can provide reliable estimates of fundamental physiological parameters that are usually obtained in more time consuming and costly chemostat experiments. The combination of culture experiments, physiological modelling and in situ data from the BIOSOPE cruise show that coccolithophore growth in the deep BIOSOPE niche is co-limited by availability of light and nitrate. This study contributes to the understanding of Emiliania huxleyi physiology, metabolism and behavior in a disadvantageous ecosystem of the ocean.

Abstract. Forest ecosystem models based on heuristic water stress functions poorly predict tropical forest response to drought because they do not capture the diversity of hydraulic traits (including variation in tree size) observed in tropical forests. We developed a Richards’ equation-based model of plant hydraulics in which all parameters of its constitutive equations are biologically-interpretable and measureable plant hydraulic traits (e.g., turgor loss point πtlp, bulk elastic modulus ε, hydraulic capacitance Cft, xylem hydraulic conductivity ks,max, water potential at 50 % loss of conductivity for both xylem (P50,x) and stomata (P50,gs), and the leaf:sapwood area ratio Al:As). We embedded this plant hydraulics model within a forest simulator (TFS) that modeled individual tree light environments and their upper boundary condition (transpiration) as well as provided a means for parameterizing individual variation in hydraulic traits. We synthesized literature and existing databases to parameterize all hydraulic traits as a function of stem and leaf traits wood density (WD), leaf mass per area (LMA) and photosynthetic capacity (Amax) and evaluated the coupled model’s (TFS-Hydro) predictions against diurnal and seasonal variability in stem and leaf water potential as well as stand-scaled sap flux. Our hydraulic trait synthesis revealed coordination among leaf and xylem hydraulic traits and statistically significant relationships of most hydraulic traits with more easily measured plant traits. Using the most informative empirical trait-trait relationships derived from this synthesis, the TFS-Hydro model parameterization is capable of representing patterns of coordination and trade-offs in hydraulic traits. TFS-Hydro successfully captured individual variation in leaf and stem water potential due to increasing tree size and light environment, with model representation of hydraulic architecture and plant traits exerting primary and secondary controls, respectively, on the fidelity of model predictions. The plant hydraulics model made substantial improvements to simulations of total ecosystem transpiration under control conditions, but the absence of a vertically stratified soil hydrology model precluded improvements to the simulation of drought response. Remaining uncertainties and limitations of the trait paradigm for plant hydraulics modeling are highlighted.
A SOLUTION TO LOW RFM FITTING PRECISION OF PLANETARY ORBITER IMAGES CAUSED BY EXPOSURE TIME CHANGING
Authors: Liu B. , Xu B. , Di K. , Jia M.
Published: June 2016

Abstract. In this paper, we propose a new solution to the low RFM fitting precision caused by exposure time changing using sensor correction. First, we establish a new rigorous geometric model, with the same ephemerides, attitudes and sensor design parameters of Chang’E-2 and HRSC images, using an equal exposure time of each scan line. The original rigorous geometric model is also established. With a given height, we can establish the correspondence between the two rigorous models. Then we generate a sensor corrected image by resampling the original image using an average elevation or a digital elevation model. We found that the sensor corrected images can be used for topographic mapping which maintains almost the same precision of the original images under certain conditions. And RFM can fit rigorous geometric model of the sensor corrected image very well. Preliminary experimental results show that the RMS residual error of the RFM fitting can reach to 1/100 pixel level too. Using the proposed solution, sensors with changing exposure time can be precisely modelled by the generic RFM.
A LIBRATION MODEL FOR ENCELADUS BASED ON GEODETIC CONTROL POINT NETWORK ANALYSIS
Authors: Nadezhdina I. E. , Zubarev A. E. , Brusnikin E. S. , Oberst J.
Published: June 2016

Abstract. A new global control point network was derived for Enceladus, based on Cassini and Voyager-2 image data. Cassini images were taken from 2005 to 2014, for Voyager we have only one flyby in the middle of 1981. We have derived 3D Cartesian coordinates for 1128 control points as well as improved pointing data for 12 Voyager and 193 Cassini images in the Enceladus-fixed coordinate system. The point accuracies vary from 55 m to 2900 m (average point accuracy – 221 m). From tracking of the control points we detect a librational motion described by a model which includes 3 different periods and amplitudes (Rambaux et al., 2011). We determine the amplitudes for each term. Our new control point network has a higher number of point measurements and a higher accuracy than previous data (Giese et al., 2014).
PROVIDING R-TREE SUPPORT FOR MONGODB

Published: June 2016

Abstract. Supporting large amounts of spatial data is a significant characteristic of modern databases. However, unlike some mature relational databases, such as Oracle and PostgreSQL, most of current burgeoning NoSQL databases are not well designed for storing geospatial data, which is becoming increasingly important in various fields. In this paper, we propose a novel method to provide R-tree index, as well as corresponding spatial range query and nearest neighbour query functions, for MongoDB, one of the most prevalent NoSQL databases. First, after in-depth analysis of MongoDB’s features, we devise an efficient tabular document structure which flattens R-tree index into MongoDB collections. Further, relevant mechanisms of R-tree operations are issued, and then we discuss in detail how to integrate R-tree into MongoDB. Finally, we present the experimental results which show that our proposed method out-performs the built-in spatial index of MongoDB. Our research will greatly facilitate big data management issues with MongoDB in a variety of geospatial information applications.

Published: June 2016

Abstract. This paper summarizes the general requirements and specific characteristics of both geospatial raster database management system and raster data processing platform from a domain-specific perspective as well as from a computing point of view. It also discusses the need of tight integration between the database system and the processing system. These requirements resulted in Oracle Spatial GeoRaster, a global scale and high performance earth imagery and raster data management and processing platform. The rationale, design, implementation, and benefits of Oracle Spatial GeoRaster are described. Basically, as a database management system, GeoRaster defines an integrated raster data model, supports image compression, data manipulation, general and spatial indices, content and context based queries and updates, versioning, concurrency, security, replication, standby, backup and recovery, multitenancy, and ETL. It provides high scalability using computer and storage clustering. As a raster data processing platform, GeoRaster provides basic operations, image processing, raster analytics, and data distribution featuring high performance computing (HPC). Specifically, HPC features include locality computing, concurrent processing, parallel processing, and in-memory computing. In addition, the APIs and the plug-in architecture are discussed.
USER PREFERENCES IN IMAGE MAP USING
Authors: Vondráková A. , Vozenilek V.
Published: June 2016

Abstract. In the process of map making, the attention is given to the resulting image map (to be accurate, readable, and suit the primary purpose) and its user aspects. Current cartography understands the user issues as all matters relating to user perception, map use and also user preferences. Most commercial cartographic production is strongly connected to economic circumstances. Companies are discovering user’s interests and market demands. However, is it sufficient to focus just on the user’s preferences? Recent research on user aspects at Palacký University Olomouc addresses a much wider scope of user aspects. The user’s preferences are very often distorting – the users think that the particular image map is kind, beautiful, and useful and they wants to buy it (or use it – it depends on the form of the map production). But when the same user gets the task to use practically this particular map (such as finding the shortest way), so the user concludes that initially preferred map is useless, and uses a map, that was worse evaluated according to his preferences. It is, therefore, necessary to evaluate not only the correctness of image maps and their aesthetics but also to assess the user perception and other user issues. For the accomplishment of such testing, eye-tracking technology is a useful tool. The research analysed how users read image maps, or if they prefer image maps over traditional maps. The eye tracking experiment on the comparison of the conventional and image map reading was conducted. The map readers were asked to solve few simple tasks with either conventional or image map. The readers’ choice of the map to solve the task was one of investigated aspect of user preferences. Results demonstrate that the user preferences and user needs are often quite different issues. The research outcomes show that it is crucial to implement map user testing into the cartographic production process.

Published: June 2016

Abstract. This paper discusses the potential of current photogrammetric multi-head oblique cameras, such as UltraCam Osprey, to improve the efficiency of standard photogrammetric methods for surveying applications like inventory surveys and topographic mapping for public administrations or private customers. In 2015, Terra Messflug (TM), a subsidiary of Vermessung AVT ZT GmbH (Imst, Austria), has flown a number of urban areas in Austria, Czech Republic and Hungary with an UltraCam Osprey Prime multi-head camera system from Vexcel Imaging. In collaboration with FBK Trento (Italy), the data acquired at Imst (a small town in Tyrol, Austria) were analysed and processed to extract precise 3D topographic information. The Imst block comprises 780 images and covers an area of approx. 4.5 km by 1.5 km. Ground truth data is provided in the form of 6 GCPs and several check points surveyed with RTK GNSS. Besides, 3D building data obtained by photogrammetric stereo plotting from a 5 cm nadir flight and a LiDAR point cloud with 10 to 20 measurements per m² are available as reference data or for comparison. The photogrammetric workflow, from flight planning to Dense Image Matching (DIM) and 3D building extraction, is described together with the achieved accuracy. For each step, the differences and innovation with respect to standard photogrammetric procedures based on nadir images are shown, including high overlaps, improved vertical accuracy, and visibility of areas masked in the standard vertical views. Finally the advantages of using oblique images for inventory surveys are demonstrated.

Published: June 2016

Abstract. Oblique airborne photogrammetry is rapidly maturing and being offered by service providers as a good alternative or replacement of the more traditional vertical imagery and for very different applications (Fig.1). EuroSDR, representing European National Mapping Agencies (NMAs) and research organizations of most EU states, is following the development of oblique aerial cameras since 2013, when an ongoing activity was created to continuously update its members on the developments in this technology. Nowadays most European NMAs still rely on the traditional workflow based on vertical photography but changes are slowly taking place also at production level. Some NMAs have already run some tests internally to understand the potential for their needs whereas other agencies are discussing on the future role of this technology and how to possibly adapt their production pipelines. At the same time, some research institutions and academia demonstrated the potentialities of oblique aerial datasets to generate textured 3D city models or large building block models. The paper provides an overview of tests, best practices and considerations coming from the R&D community and from three European NMAs concerning the use of oblique aerial imagery.

Abstract. Techniques for 3D mapping are maturing. At the same time the need for 3D data is increasing. This has pushed national (and regional) mapping agencies (NMAs) to consider extending their traditional task of providing topographic data into the third dimension. To show how research results in 3D mapping obtained over the past twenty years have been adopted by practice, this paper presents the ongoing work on 3D mapping within seven NMAs, all member of the 3D Special Interest Group of European Spatial Data Research (EuroSDR). The paper shows that some NMAs are still in the initial (experimental) phase of 3D mapping, while others have already built solid databases to maintain 2.5D and 3D topographic data covering their whole country.

BORDERLESS GEOSPATIAL WEB (BOLEGWEB)
Authors: Cetl V. , Kliment T. , Kliment M.
Published: June 2016

Abstract. The effective access and use of geospatial information (GI) resources acquires a critical value of importance in modern knowledge based society. Standard web services defined by Open Geospatial Consortium (OGC) are frequently used within the implementations of spatial data infrastructures (SDIs) to facilitate discovery and use of geospatial data. This data is stored in databases located in a layer, called the invisible web, thus are ignored by search engines. SDI uses a catalogue (discovery) service for the web as a gateway to the GI world through the metadata defined by ISO standards, which are structurally diverse to OGC metadata. Therefore, a crosswalk needs to be implemented to bridge the OGC resources discovered on mainstream web with those documented by metadata in an SDI to enrich its information extent. A public global wide and user friendly portal of OGC resources available on the web ensures and enhances the use of GI within a multidisciplinary context and bridges the geospatial web from the end-user perspective, thus opens its borders to everybody. Project “Crosswalking the layers of geospatial information resources to enable a borderless geospatial web” with the acronym BOLEGWEB is ongoing as a postdoctoral research project at the Faculty of Geodesy, University of Zagreb in Croatia (http://bolegweb.geof.unizg.hr/). The research leading to the results of the project has received funding from the European Union Seventh Framework Programme (FP7 2007-2013) under Marie Curie FP7-PEOPLE-2011-COFUND. The project started in the November 2014 and is planned to be finished by the end of 2016. This paper provides an overview of the project, research questions and methodology, so far achieved results and future steps.
INDOORGML – A STANDARD FOR INDOOR SPATIAL MODELING
Authors: Li Ki-Joune
Published: June 2016

Abstract. With recent progress of mobile devices and indoor positioning technologies, it becomes possible to provide location-based services in indoor space as well as outdoor space. It is in a seamless way between indoor and outdoor spaces or in an independent way only for indoor space. However, we cannot simply apply spatial models developed for outdoor space to indoor space due to their differences. For example, coordinate reference systems are employed to indicate a specific position in outdoor space, while the location in indoor space is rather specified by cell number such as room number. Unlike outdoor space, the distance between two points in indoor space is not determined by the length of the straight line but the constraints given by indoor components such as walls, stairs, and doors. For this reason, we need to establish a new framework for indoor space from fundamental theoretical basis, indoor spatial data models, and information systems to store, manage, and analyse indoor spatial data. In order to provide this framework, an international standard, called IndoorGML has been developed and published by OGC (Open Geospatial Consortium). This standard is based on a cellular notion of space, which considers an indoor space as a set of non-overlapping cells. It consists of two types of modules; core module and extension module. While core module consists of four basic conceptual and implementation modeling components (geometric model for cell, topology between cells, semantic model of cell, and multi-layered space model), extension modules may be defined on the top of the core module to support an application area. As the first version of the standard, we provide an extension for indoor navigation.
INTEGRATION OF REMOTELY SENSED DATA INTO GEOSPATIAL REFERENCE INFORMATION DATABASES. UN-GGIM NATIONAL APPROACH
Authors: Arozarena A. , Villa G. , Valcárcel N. , Pérez B.
Published: June 2016

Abstract. Remote sensing satellites, together with aerial and terrestrial platforms (mobile and fixed), produce nowadays huge amounts of data coming from a wide variety of sensors. These datasets serve as main data sources for the extraction of Geospatial Reference Information (GRI), constituting the “skeleton” of any Spatial Data Infrastructure (SDI). Since very different situations can be found around the world in terms of geographic information production and management, the generation of global GRI datasets seems extremely challenging. Remotely sensed data, due to its wide availability nowadays, is able to provide fundamental sources for any production or management system present in different countries. After several automatic and semiautomatic processes including ancillary data, the extracted geospatial information is ready to become part of the GRI databases. In order to optimize these data flows for the production of high quality geospatial information and to promote its use to address global challenges several initiatives at national, continental and global levels have been put in place, such as European INSPIRE initiative and Copernicus Programme, and global initiatives such as the Group on Earth Observation/Global Earth Observation System of Systems (GEO/GEOSS) and United Nations Global Geospatial Information Management (UN-GGIM). These workflows are established mainly by public organizations, with the adequate institutional arrangements at national, regional or global levels. Other initiatives, such as Volunteered Geographic Information (VGI), on the other hand may contribute to maintain the GRI databases updated. Remotely sensed data hence becomes one of the main pillars underpinning the establishment of a global SDI, as those datasets will be used by public agencies or institutions as well as by volunteers to extract the required spatial information that in turn will feed the GRI databases. This paper intends to provide an example of how institutional arrangements and cooperative production systems can be set up at any territorial level in order to exploit remotely sensed data in the most intensive manner, taking advantage of all its potential.

Published: June 2016

Abstract. FORMOSAT-2, Taiwan’s first remote sensing satellite, was successfully launched in May of 2004 into the Sun-synchronous orbit at 891 kilometers of altitude. With the daily revisit feature, the 2-m panchromatic, 8-m multi-spectral resolution images captured have been used for researches and operations in various societal benefit areas. This paper details the orchestration of various tasks conducted in different institutions in Taiwan in the efforts responding to international disasters. The institutes involved including its space agency-National Space Organization (NSPO), Center for Satellite Remote Sensing Research of National Central University, GIS Center of Feng-Chia University, and the National Center for High-performance Computing. Since each institution has its own mandate, the coordinated tasks ranged from receiving emergency observation requests, scheduling and tasking of satellite operation, downlink to ground stations, images processing including data injection, ortho-rectification, to delivery of image products. With the lessons learned from working with international partners, the FORMOSAT Image Processing System has been extensively automated and streamlined with a goal to shorten the time between request and delivery in an efficient manner. The integrated team has developed an Application Interface to its system platform that provides functions of search in archive catalogue, request of data services, mission planning, inquiry of services status, and image download. This automated system enables timely image acquisition and substantially increases the value of data product. Example outcome of these efforts in recent response to support Sentinel Asia in Nepal Earthquake is demonstrated herein.
TREE STEM RECONSTRUCTION USING VERTICAL FISHEYE IMAGES: A PRELIMINARY STUDY
Authors: Berveglieri A. , Tommaselli A. M. G.
Published: June 2016

Abstract. A preliminary study was conducted to assess a tree stem reconstruction technique with panoramic images taken with fisheye lenses. The concept is similar to the Structure from Motion (SfM) technique, but the acquisition and data preparation rely on fisheye cameras to generate a vertical image sequence with height variations of the camera station. Each vertical image is rectified to four vertical planes, producing horizontal lateral views. The stems in the lateral view are rectified to the same scale in the image sequence to facilitate image matching. Using bundle adjustment, the stems are reconstructed, enabling later measurement and extraction of several attributes. The 3D reconstruction was performed with the proposed technique and compared with SfM. The preliminary results showed that the stems were correctly reconstructed by using the lateral virtual images generated from the vertical fisheye images and with the advantage of using fewer images and taken from one single station.

Abstract. Recent advances in automation of photogrammetric 3D modelling software packages have stimulated interest in reconstructing highly accurate 3D object geometry in unconventional environments such as underwater utilizing simple and low-cost camera systems. The accuracy of underwater 3D modelling is affected by more parameters than in single media cases. This study is part of a larger project on 3D measurements of temporal change of coral cover in tropical waters. It compares the accuracies of 3D point clouds generated by using images acquired from a system camera mounted in an underwater housing and the popular GoPro cameras respectively. A precisely measured calibration frame was placed in the target scene in order to provide accurate control information and also quantify the errors of the modelling procedure. In addition, several objects (cinder blocks) with various shapes were arranged in the air and underwater and 3D point clouds were generated by automated image matching. These were further used to examine the relative accuracy of the point cloud generation by comparing the point clouds of the individual objects with the objects measured by the system camera in air (the best possible values). Given a working distance of about 1.5 m, the GoPro camera can achieve a relative accuracy of 1.3 mm in air and 2.0 mm in water. The system camera achieved an accuracy of 1.8 mm in water, which meets our requirements for coral measurement in this system.

Published: June 2016

Abstract. Presenting the outcomes of a capacity building activity, this contribution illustrates a replicable recording methodology to obtain timely, relevant and accurate information about conditions, materials and transformations of heritage structures. The purpose of the presented training activity consisted in developing local capabilities for the documentation of the built heritage at Bagan, Myanmar, employing different IT-supported techniques. Under the Director of UNESCO, the direct supervision of the chief of the culture unit, and in close consultation and cooperation with the Association of Myanmar Architects, the Department of Archaeology National Museum and Library (DoA) a documentation strategy has been developed in order to set up a recording methodology for the over three thousand Bagan monuments. The site, located in central Myanmar, in South East Asia, was developed between the IX and the XIII century as capital of the Myanmar kingdom. In the last years, this outstanding site has been exposed to an increasing number of natural hazards including earthquakes and flooding that strongly affected its built structures. Therefore, a documentation strategy to quickly capture shape, color, geometry and conditions of the monuments, in order to develop proper conservation projects, was needed. The scope of the training activity consisted in setting up a recording strategy updating the existing Bagan inventory, using three Buddhist temples as pilot cases study. The three documented temples were different in size, construction period, conditions and shape. The documentation included several IT-supported techniques including: Electronic Distance Measurements (EDM), SFM Photogrammetry, Laser Scanning, Record Photography as well as hand measurement and field notes. The monuments’ surveying has been developed in accordance with the guidelines and standards established by the ICOMOS International Committee for Documentation of Cultural Heritage (CIPA). Recommendations on how to extend the adopted methodology to the other Bagan monuments have been also elaborated.
A GCMs-based mathematic model for droughts prediction in the Haihe Basin, China: Multi-GCM Divide-Integration

Published: June 2016

Abstract. Recently, the skilful prediction of climate change has drawn high attention from the scientific community. Evidence has been reported the skill of prediction is not satisfactory for the magnitude of inter-annual precipitation and extreme precipitation, and at a smaller spatial scale as well. Based on observational data sets and outputs from the Global Climate Models (GCMs), this study aims at achieving a mathematical model, named multi-GCM divide-integration model (MGDI). The MGDI model is developed by hybridizing finer spatial scale and multi-linear regression model (MLRM) on five state-of-art of GCMs to improve the skills of five GCMs, which is applied to the second level of water resources regionalization in China. It is found that the performance after MGDI model correction has been improved significantly over that of individual GCMs. The errors between observation and simulation after correction (1.6 % ~ 4.4%) are within the margin of error (smaller than 5 %) and all of the varying trends in each second level of water resources regionalization were same. Furthermore, this study also used the MGDI model to predict the variation of precipitation and droughts at different spatial scale, including second level of water resources regionalization of China and the whole HHB, for the next 40 years. Predictions indicate the climate will gradually change from drying to wetting over the HHB wherein the trend of annual rainfall is 9.3 mm/10 a. The frequency of drought events will be decreasing as time goes on. The occurrence of mild and severe drought in the Luan River and Jidong Coastal, Tuhai majia River are higher than that in other regions, 9 and 8 respectively. These findings would provide scientific support for current water resources management and future drought-resisting planning of districts in China.
Impact of the physico-chemical properties of fen peat on the metal accumulation patterns in mires of Latvia

Published: June 2016

The article presents a study of the physico-chemical properties of fen peat and their influence on the metal accumulation patterns in three Latvian fens: Svētupes Mire, Elku Mire and Vīķu Mire. Full peat profiles were obtained at all study sites and analysed with a multi-proxy approach. The content of metals in fen peat was determined using the atomic absorption spectroscopy (AAS) and normalised to the concentration of Ti in the studied peat profiles. Both the character of deposits and agricultural land use in the mire catchment areas were taken into account and the possible natural and anthropogenic metal supply sources were evaluated. The content of metals in the studied fen peat significantly varied due to the heterogeneity of fen environment; however, noticeable similarities were also traced throughout all study sites. The results indicate an increased amount of transition metals and Pb in the upper peat layer. This can be explained by a direct impact from anthropogenic sources (agricultural land use, pollution, etc.). Metal binding in fen peat profiles is directly related to the alkali and alkaline earth metal content in peat, as Ca, Mg, Na and K ions are replaced by more tightly bound metal ions. In raised bogs, in turn, metal binding is associated with the acidic functional groups common to peat.
Faculty Experience Teaching in an Interdisciplinary First-Year Seminar Program: The Case of the University of Guelph
Authors: Murray Jacqueline , Wolf Peter
Published: June 2016

First-year seminar programs have been a feature on the landscape of post-secondary teaching and learning in the United States, since they first appeared in the 1880s at Boston University (Mamrick, 2005). More recently, they have begun to appear at Canadian universities. For example, first-year seminars were introduced a decade ago at the University of Guelph, as a campus-wide initiative. To recognize the first decade that these unique, interdisciplinary seminars have been offered, faculty were surveyed to understand better the impact of the program on those teaching in it, as well as their perceptions of their students. The experience of the University of Guelph suggests first-year seminar programs can have a significant influence on the teaching and professional experience of faculty and encourages them to extend their networks beyond the department and across the campus. Significantly, seminars serve as sites for pedagogical experimentation that can influence departmental curricula. Faculty who teach a first-year seminar have high satisfaction and report myriad benefits to morale, teaching, and research. The salutary effects of a first-year seminar program are not local but would be transferable across post-secondary institutions.
Aux États-Unis, on a beaucoup parlé des programmes de séminaires de première année dans le paysage de la pédagogie dans l’enseignement supérieur, depuis leur première apparition dans les années 1880 à l’Université de Boston (Mamrick, 2005). Plus récemment, ils ont commencé à apparaître dans les universités canadiennes. Par exemple, des séminaires de première année ont été introduits il y a dix ans à l’Université de Guelph en tant qu’initiative à l’échelle du campus. Afin de marquer la première décennie au cours de laquelle ces séminaires interdisciplinaires uniques ont été offerts, une enquête a été menée auprès des professeurs pour mieux comprendre les effets du programme sur les enseignants, ainsi que les perceptions de leurs étudiants. L’expérience de l’Université de Guelph suggère que les programmes de séminaires de première année peuvent avoir une influence importante sur l’enseignement et sur l’expérience professionnelle des professeurs et peuvent les encourager à élargir leur réseau au-delà du département et sur tout le campus. Il est significatif de constater que les séminaires servent de sites pour des expériences pédagogiques qui peuvent influencer les programmes d’études départementaux. Les professeurs qui enseignent un séminaire de première année en retirent une grande satisfaction et rapportent une myriade d’avantages pour le moral, l’enseignement, et la recherche. Les effets salutaires d’un programme de séminaires de première année ne sont pas ressentis uniquement au niveau local, ils sont transférables à tous les établissement d’enseignement supérieur.
Francisco Franco, articulista de incógnito (1945–1960)
Authors: Sánchez Illán Juan Carlos , Lumbreras Martínez Daniel
Published: June 2016

Se trata de un análisis pormenorizado de los artículos publicados por Francisco Franco en el periódico Arriba entre los años 1945 y 1960 bajo los seudónimos de Jakim Boor, Hispanicus y Macaulay. Se lleva a cabo su disección en dos grandes categorías: enemigos del Régimen y política, economía y sociedad. Para ello, se toma como ejemplo el propio artículo de Hispanicus titulado “Lo político, lo económico y lo social”. En la primera de las dos grandes categorías se agrupan todos aquellos elementos abstractos -instituciones o ideologías- que Franco consideraba perjudiciales para la España que él gobernaba o que históricamente habían sido hostiles a este país; en la segunda se recogen el comentario sobre política en términos actuales o generales, las situaciones económicas y sociales así como los numerosos fragmentos de Historia de España que el dictador gustaba de incluir en sus colaboraciones periodísticas.
Peruanos y bolivianos en la sátira chilena de la Guerra del Pacífico (1879 - 1884)
Authors: Ibarra Cifuentes Patricio
Published: June 2016

A partir de los grabados publicados en las páginas de los periódicos que incluyeron humor gráfico en sus ediciones durante la Guerra del Pacífico (1879 - 1883), los caricaturistas chilenos desplegaron un discurso visual agresivo en clave patriótica y belicista, donde presentaron a sus lectores una imagen crítica y despectiva respecto de los adversarios de Chile. Recalcaron la supuesta falta de ánimo y valor combativo, ante la sola presencia de los efectivos militares chilenos tanto en el mar como en tierra. Así, la tinta y el papel, se transformaron en otra de las armas que intervinieron en el conflicto de Chile contra el Perú y Bolivia por la posesión de los ricos territorios salitreros de Tarapacá y Antofagasta. Las imágenes fueron interpretadas a partir de los postulados de la Escuela de Warburg, en especial los de Erwin Panofsky, que propone tres niveles de estudio del significado de cada obra, a saber, la “descripción preiconográfica”, luego el “estudio iconográfico” en cuanto tal y, finalmente, la “interpretación iconológica”.
Entre la representación y la figuración. El cine de la Nouvelle Vague: una revisión histórica
Authors: Vilaró i Moncasí Arnau
Published: June 2016

Cincuenta años después del nacimiento de la Nouvelle Vague, sus herencias recibidas en el cine contemporáneo son inevitables. Figuras y motivos visuales; relatos, temas, rostros o lugares comunes; recursos estéticos y de lenguaje. Los ecos se manifiestan de diversos modos, cada filiación implica una relación distinta y por tanto una aproximación dispar para su análisis. Y sin embargo, tanto la academia como la crítica de cine siguen pensando en la Nouvelle Vague como un conjunto, un universo, una corriente o una tendencia estética. Pero, ¿existe una estética nouvellevaguesca? Y, si es así, ¿por qué abordar de nuevo su revisión histórica? A partir de las tesis de Deleuze sobre la imagen-tiempo y de la aseveración de Serge Daney según la cual la Nouvelle Vague contribuyó al paso de un cine del ideal a un cine de la alteridad, el artículo siguiente da respuesta a estas preguntas partiendo de la convicción que los cineastas franceses no crearon un estilo, sino que asentaron un método. Este método consistiría en poner en crisis una relación propia de la narración para hallar una nueva relación en términos de montaje y puesta en escena. En particular, el artículo sostiene que la Nouvelle Vague aboga por esta aproximación haciendo del filme el espacio que permite pensar la visibilidad de la imagen y su figurabilidad a partir de la búsqueda y la pérdida del objeto de deseo en el relato, de lo que resulta una lógica de las imágenes a medio camino entre la representación y la figuración. Para abordar el análisis, el artículo propone una revisión de las primeras obras de François Truffaut, Jean-Luc Godard y Alain Resnais, y el cine de Philippe Garrel como representante de la primera generación francesa después de la Nouvelle Vague.

Italian Fashion in the Latest Decades: From Its Original Features to the “New Vocabulary”
Authors: Calefato Patrizia
Published: June 2016

“Made in Italy” is an indication of origin, recorded and rooted in history, society, and the imaginary world; it is a “half-brand” that, in the latest years of the twentieth century, aimed at characterizing Italian products and its tradition in a clear way. This article aims at pinpointing some elements of fashion theory with reference to Italy. After outlining certain historical original traits of the Italian style, I will point out the characteristics of the two “long waves” of the Made in Italy brand: the first one that dates from the Sixties to the Eighties, and the second one from the late Nineties to the present.
