Piñon–juniper (PJ) fire regimes are generally characterised as infrequent high-severity. However, PJ ecosystems vary across a large geographic and bio-climatic range and little is known about one of the principal PJ functional types, PJ savannas. It is logical that (1) grass in PJ savannas could support frequent, low-severity fire and (2) exclusion of frequent fire could explain increased tree density in PJ savannas. To assess these hypotheses I used dendroecological methods to reconstruct fire history and forest structure in a PJ-dominated savanna. Evidence of high-severity fire was not observed. From 112 fire-scarred trees I reconstructed 87 fire years (1547–1899). Mean fire interval was 7.8 years for fires recorded at ≥2 sites. Tree establishment was negatively correlated with fire frequency (r=–0.74) and peak PJ establishment was synchronous with dry (unfavourable) conditions and a regime shift (decline) in fire frequency in the late 1800s. The collapse of the grass-fuelled, frequent, surface fire regime in this PJ savanna was likely the primary driver of current high tree density (mean=881treesha–1) that is >600% of the historical estimate. Variability in bio-climatic conditions likely drive variability in fire regimes across the wide range of PJ ecosystems.

The article discusses possibilities of geochronological tracking technology for studying the spatial mobility of social groups in Russia in the past. The GIS proposed is necessary to visualize and analyze spatial data in a prosopographic research of about 400 szlachta representatives in Peter’s Epoch. Spatial mobility is understood as the intensity of person's translocation through settlements and his ability to respond to external challenges by moving. The archival materials of the Senate inspection of the szlachta (1721-1723) served the basis for the study and the resource formation. Particular attention is paid to the design of software research tools – the PostgreSQL database and the web GIS based on the latter. It is the first time when geochronological tracking as a geoinformatics method was used to prosopographically study the Russian nobility. The methods of historical source spatial data representation and visualization are implemented in the form of a geodatabase that is publicly available. Two program modules (the GIS among them) grant a wide range of Internet users an access to historical sources text data as well as synchronically visualized data on the szlachta service under Peter the first.  The authors conclude that it is promising to create a special web interface which provides users with flexible text and geodata filtering and analysis. The web project created can be used both for research in the field of social history, historical geography, genealogy and for educational purposes in such courses as “historical computer science” and “digital humanities”.

With the implementation specification of the Web Processing Service (WPS), a standard to process spatial data on the web is available from the Open Geospatial Consortium (OGC). This new possibility in web-based information systems allow an interoperable processing of different data based on service-oriented architectures. This paper describes requirements and an implementation for web-based processing and workflow creation to generate and provide remote sensing products like fire hotspot points and land surface temperatures based on NASA MODIS data. Therefore, a WPS as well as service chains to process these remote sensing products are implemented. PyWPS is used as WPS and tested with focus on processing remote sensing data. To chain the developed processes, software like 52° North Orchestration Engine, Apache ODE and internal software for executing processing chains and providing a workflow as WPS process are tested. A Web-GIS with open-source software was developed to manage started and finished processes, to search for available satellite data and to create processing chains interactively. An interface to retrieve and process archived data was integrated; the user of this system can search interactively for archived satellite data and process it with the developed processing services and workflows. The Web-GIS also acts as a WPS client, client for visualizing processed data and creator as well as security layer for processing chains. These developments and research work show that there is additional work to improve the WPS specification for example by adding domain-specific profiles for working with large raster data to define standardised rules for data-exchange between the processes. In the field of process orchestration, no standardised data format describing processing chains exists yet.

In this paper, we present the Web-based CALL environment (or WALL) which is currently being experimented with at the University of Paris 13 in the Computer Science Department of the Institut Universitaire de Technologie. Our environment is being developed to teach computer science (CS) English to CS French-speaking students, and will be extended to other languages for specific purposes such as, for example, English or French for banking, law, economics or medicine, where on-line resources are available.English, and more precisely CS English is, for our students, a necessary tool, and not an object of study. The learning activities must therefore stimulate the students' interest and reflection about language phenomena. Our pedagogical objective, relying on research acquisition (Wokusch 1997) consists in linking various texts together with other documents, such as different types of dictionaries or other types of texts, so that knowledge can be acquired using various appropriate contexts.Language teachers are not supposed to be experts in fields such as computer sciences or economics. We aim at helping them to make use of the authentic documents that are related to the subject area in which they teach English. As shown in Foucou and Kübler (1998) the wide range of resources available on the Web can be processed to obtain corpora, i.e. teaching material. Our Web-based environment therefore provides teachers with a series of tools which enable them to access information about the selected specialist subject, select appropriate specialised texts, produce various types of learning activities and evaluate students' progress.Commonly used textbooks Tor specialised English offer a wide range of learning activities, but they are based on documents that very quickly become obsolete, and that are sometimes widely modified. Moreover, they are not adaptable to the various levels of language of the students. From the students' point of view, working on obsolete texts that are either too easy or too difficult can quickly become demotivating, not to say boring.In the next section, we present the general architecture of the teaching/learning environment; the method of accessing and using it, for teachers as well as for students, is then described. The following section deals with the actual production of exercises and their limits. We conclude and present some possible research directions.

Patients undergoing radiation treatment for head and neck cancer experience significant side-effects that can impact a wide range of daily activities. Patients often report receiving insufficient information during and after treatment, which could impede rehabilitation efforts; they may also encounter practical and logistical barriers to receipt of supportive care. Thus, we developed a web-based program, My Journey Ahead, to provide information and strategies for managing symptom-focused concerns, which may be easily accessed from the patient’s home. The purpose of this study was to evaluate patient acceptability and satisfaction with the My Journey Ahead program. In Phase 1, five patients with head and neck squamous cell carcinoma (HNSCC) reviewed the web-based program and provided initial feedback, which informed program modifications. In Phase 2, 55 patients were recruited to evaluate the program. Patient assessments were obtained prior to and after use of the web-based program, and included measures of psychological distress, self-efficacy in coping with cancer-related issues, and satisfaction with the website. Among the 55 patients enrolled, 44 logged in and viewed the web-based program. Participants reported high levels of satisfaction with the information received, and indicated that the website was interesting and easy to use. Older age and higher levels of self-efficacy in coping were each associated with higher levels of satisfaction with the website. In summary, the web-based program was well-received by patients, the majority of whom found it to be informative and useful. An easy-to-use web-based program, particularly for older patients who may have difficulty locating reliable evidence-based information on the internet, may be helpful in addressing survivors’ needs in symptom management and coping with cancer.Clinical Trial Registrationhttps://clinicaltrials.gov/, NCT02442336

Fire, being both a natural and cultural phenomenon, presents problems in disentangling the historical effect of humans from that of climate change. Here, we investigate the potential impact of humans on boreal fire regimes from a perspective of fuels, ignitions and culture. Two ways for a low technology culture to impact the fire regime are as follows: (i) by altering the number of ignitions and their spatial distribution and timing and (ii) by hindering fire spread. Different cultures should be expected to have quite different impacts on the fire regimes. In northern Fennoscandia, there is evidence for fire regime changes associated with the following: a reindeer herding culture associated with few ignitions above the natural; an era of cattle husbandry with dramatically increased ignitions and somewhat higher fire frequency; and a timber exploitation era with decreasing fire sizes and diminishing fire frequency. In other regions of the boreal zone, such schemes can look quite different, but we suggest that a close look at the resource extraction and land use of different cultures should be part of any analysis of past fire regimes.

The Marine Irish Digital Atlas (MIDA) is an Internet resource built in a web GIS environment, where people interested in coastal and marine information for Ireland can visualize and identify pertinent geospatial datasets and determine where to acquire them. The atlas, which is being constantly maintained, currently displays more than 140 data layers from over 35 coastal and marine organizations both within Ireland and abroad. It also features an “InfoPort” which is a repository of text, imagery, links to spatial data sources and additional reference material for a wide range of coastal and marine topics. The MIDA team has been active in the creation of the International Coastal Atlas Network and the Atlas was chosen as one of the nodes for the Semantic Interoperability Demonstrator.


The chapter presents examples of applications and study cases of platforms of geospatial decision support systems for national public policies and strategies. The rapid progress of internet with the combination of GIS has paved the ways for web distribution of spatial data. Users can access the spatial data through a Web-GIS website, make thematic maps, and perform all types of spatial queries and analysis. In the context of an increasing emphasis on decentralized planning, the need for collection and dissemination of data at local levels has been increased. Use of the web as a dissemination medium of geographic data in the form of interactive maps can be regarded as a major advancement in digital cartography and opens many new opportunities, such as real-time maps, cheaper dissemination, and decentralized sharing of geographic information.

Spatial depictions of fire regimes are indispensable to fire management because they portray important characteristics of wildland fire, such as severity, intensity, and pattern, across a landscape that serves as important reference for future treatment activities. However, spatially explicit fire regime maps are difficult and costly to create requiring extensive expertise in fire history sampling, multivariate statistics, remotely sensed image classification, fire behaviour and effects, fuel dynamics, landscape ecology, simulation modelling, and geographical information systems (GIS). This paper first compares three common strategies for predicting fire regimes (classification, empirical, and simulation) using a 51�000�ha landscape in the Selway-Bitterroot Wilderness Area of Montana, USA. Simulation modelling is identified as the best overall strategy with respect to developing temporally deep spatial fire patterns, but it has limitations. To illustrate these problems, we performed three simulation experiments using the LANDSUM spatial model to determine the relative importance of (1) simulation time span; (2) fire frequency parameters; and (3) fire size parameters on the simulation of landscape fire return interval. The model used to simulate fire regimes is also very important, so we compared two spatially explicit landscape fire succession models (LANDSUM and FIRESCAPE) to demonstrate differences between model predictions and limitations of each on a neutral landscape. FIRESCAPE was developed for simulating fire regimes in eucalypt forests of south-eastern Australia. Finally, challenges for future simulation and fire regime research are presented including field data, scale, fire regime variability, map obsolescence, and classification resolution.
