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.

In an era of globalization, economies over the world have become increasingly international and competitive. According to Alahuhta et al (2005), the last three decade has seen a massive revolution in technology use at both individual and organizations level with several organizations replacing the manual system of operation with modern technologies and computer powered machines. Acheampong, et al (2017) explain that three decades ago it was a dream to conceive that at a point in time all of the world’s knowledge could be put on a single world wide web and browsed by people from different parts of the world for free. These are the realities of the contemporary business place which Casey & Wilson-Evered (2012) explained has been facilitated by the advances in technology and globalization. According to Zaremohzzabieh, et al (2014), e-commerce platform appeared along with the development of internet and the necessities of ventures has given a web-based exchanging spot to customers and suppliers. It is a virtual system for purchasers and merchants, utilizing computer programming technology to coordinate assets on the web and accomplish the objective of community program (Ruzzier, AntonciC, Hisrich, & Konecnik, 2007). E-commerce platform gives all members equivalent and public information location of many services. Merchants can disseminate product information on e-commerce platforms, while purchasers can get a wide range of information without going outside (Strauss, 2016). As a new trend in the economic development and a new pattern of future business advancement, e-commerce platform plays a critical part with many attributes i.e. third party, service nature, neutrality and integration (Ling, et al, 2010).

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”.

Databases and the World Wide Web have overwhelmed the information market. Bibliographic reference databases with links to electronic journals that publish full text manuscripts provide information seekers with a wide range of fast and convienient searching methods. Increasingly organisations present their activities on the WWW which allows them to disseminate updated information about their experts, publications and on-going research projects better than was possible previously. The web technology has a major advantage over printed products since it allows end-users to search, browse and print the information in different formats according to their own specific needs. Agricultural and food science papers published in Finland have been documented annually in this journal for a number of years, but the advent of web technologies have made this much less valuable.;

Geographic Information System (GIS) is a tool used for capture, storage, manipulation, query and presentation of spatial data that have applicability in diverse fields. Web GIS has put GIS on Web, that made it available to common public which was earlier used by few elite users. In the present paper, development of Web GIS frameworks has been explained that provide the requisite knowledge for creating Web based GIS applications. Open Source Software (OSS) have been used to develop two Web GIS frameworks. In first Web GIS framework, WAMP server, ALOV, Quantum GIS and MySQL have been used while in second Web GIS framework, Apache Tomcat server, GeoServer, Quantum GIS, PostgreSQL and PostGIS have been used. These two Web GIS frameworks have been critically compared to bring out the suitability of each for a particular application as well as their performance. This will assist users in selecting the most suitable one for a particular Web GIS application.

Wildfire is one of the complex and damaging natural phenomena in the world. Wildfires pose an enormous challenge to predict and monitor complicated integration chemistry with the physical aspects of solid-gas stage combustion and heat transmission spatially diverse vegetations, topography, and detailed time and space conditions at various spatial and time scales. The research community has greatly enhanced its efforts in the last 25 years to better understand wildfires by improving observation, measurement, analysis and modelling. The fast development of spatial data analysis and computer technology has been facilitated. This combination allowed new decision promotion systems, information collection, analysis methods, growth, and existing fire management instruments. In several countries, despite this activity, forest fires remain a serious problem. Factors that raise the world risk of wildfires are climate change, urban-rural migration and the creation of the interface between urban and wildlands. These events demonstrate the tremendous destructive force of wildfires of great magnitude, sometimes well beyond our concrete containment and control capability. In addition to firefighters, foresters and other organised systems, the scientific community is key to addressing the problems of fire recognition in the countryside. Advances in our understanding of fire-fighting mechanisms and the relationship between fire activity and the natural and constructed environment can lead to successful fire risk decision support systems, the predictions for fire propagation and the reduction of fire risk. The convergence of forest ecosystems and forest fires has become the growing threat posed by human influences and other factors to ecosystems, resources and even human lives. Climate change will change forest fire regimes to enhance forest fire understanding and to build strategies for mitigation and adaptation. The study highlights broad aspects of forest fire in combination with

According to information scientists, information is modified into knowledge by adding experience. Researchers need powerful and successful filters to help them stay abreast of literature in their field, as well as methods to track the impact of their own research in often very specialized areas of interest. Traditional mechanisms such as peer review and citation searching using bibliometrics are no longer sufficient tools to aid researchers. How can librarians become leaders and powerful allies in this new landscape? Enter the world of Altmetrics. Altmetrics, or alternative citation metrics, provides researchers and scholars with new ways to track influence across a wide range of media and platforms. Altmetrics are metrics and qualitative data that are complementary to traditional, citation-based metrics. Altmetrics is a field of web-based metrics that accounts for total author influence which also looks beyond journal and monographic citation counts to the social web. The aim of this chapter is to explain the concept of library and librarian involvement with altmetrics.

This chapter describes a prototype Web geographic information system (GIS) and spatial model application for mapping person crime rates in Brisbane, Australia. Our application, which integrates GIS functionality, a clustering model, client/server technology and the Internet, can generate useful documents such as maps and tables to examine and present crime patterns in space and time. Our chapter also demonstrates the usefulness and appeal of the Web GIS application as an information dissemination and spatial data analysis tool for promoting public awareness of social conditions. This chapter argues that Web-based data access is a better approach to delivering large volumes of crime data and geographical information to the public. We expect that police, community workers and citizens could utilize the application and associated maps to facilitate and enhance crime prevention activities. We note, however, that further development of Web-based GIS applications need to answer a number of pertinent questions regarding system maintenance, data integrity and neighborhood crime prevention.
