Abstract: We evaluated the differences existing in the public information presented by local administrative units in Romania by analyzing the websites of 3175 local administrative units based on a standard database which contains 17 indicators (grouped into three categories: identification, content and administrative support). We used descriptive statistics for analyzing results and ArcGis 10 for mapping the geographical patterns of distribution. 2769 local administrative units (87.09%) have a dedicated website, but the information presented on them are scarce, and in a direct connection with its rank in the network of settlements. The unbalance between content indicators and the administrative support indicators reveals a politicization of the websites, detrimental to public information and participation. The lowest values of online public information (<20%) are present in counties with a high proportion of profound rural settlements or a particular ethnical distribution of population.
Abstract: The present study is attempted under four points. The first point discusses the regional trends and patterns of literacy rate by decades since 1951. The second examines the trends of literacy rate by inter-states and union territories in the study area during 1951-2011. The third observes the distribution pattern and male-female literacy differentials during 2011, while the fourth explains the factors which influence the literacy level in the study area. The study reveals that the total literacy of India increased from 18.33 per cent to 73.00 from 1951 to 2011. All the states showed positive growth in literacy rate, especially Kerala (93.91 per cent) and Mizoram (91.58 per cent) having the highest growth. The male (96.1 per cent) and female (92.1 per cent) literacy was found to be the highest in Kerala (96.1per cent). The present study concludes that lower gross enrolment ratio and high dropout rates are chief determinants of literacy in the study area. The study is based upon suitable statistical techniques to analyze the data. Finally, some suggestions have been given to enhance the level of literacy rate that may result into positive socio-cultural transformation.
Abstract: As past seismic events showed, Bucharest (capital of Romania) can be significantly affected by another intermediate depth (or subcrustal) Vrancea earthquake. The 1940 (Mw 7.7) and 1977 (Mw 7.4) earthquakes put the number of casualties in Bucharest over 1600. Although most people and authorities are aware of the exposure, the mitigation actions are still improper and there is actually a very uncertain image of the current damage extent. The paper provides scientifically based answers, through quantitative earthquake loss estimation based on recently developed analytical methods, applied for buildings in the historic centre of Bucharest. The approach offers a relevant picture of the actual possible damage distribution after an earthquake similar to the 1977 event, in an area with heavy traffic and a high number of tourists. The Improved Displacement Coefficient Method used in this study relies on the description of structural behaviour within different limits due to specific ground motion parameters like spectral acceleration. The 358 buildings in the study area are assessed individually and specific vulnerability curves are assigned to each typology, based on height, construction year and material. The same classification as in the Near Real-Time System for Estimating the Seismic Damage in Romania is used. The results are evaluated in order to be further included in the system. In addition, an empirical loss assessment procedure reflecting the economic impact of the previously calculated situation was employed. Relevant maps for mean damage ratio and economic losses are presented and interpreted.
Abstract: The increasing availability of the high spatial resolution satellite images has provided a new data source for building extraction. This paper proves the concept of object oriented classification using high-resolution satellite data (Cartosat-1 satellite data fused with IRS-1C, LISS IV data) for automatic building extraction using eCognition software. In this study, the overall accuracy of classified image is 0.94 and Kappa accuracy is 0.92. The producer accuracy for building, vegetation and shadow are 0.9745, 1.0 and 0.8999, respectively, whereas user accuracy for building, vegetation and shadow are 1.0, 0.9475 and 1.0 respectively. The classification overall accuracy is based on TTA mask (training and test area mask) and it is 0.98 and Kappa accuracy is 0.96. The producer accuracy for building, forest and shadow are 1.0, 1.0 and 0.7344, respectively and user accuracy for building, vegetation and shadow are 1.0, 0.9475 and 1.0, respectively.
Abstract: In order to evaluate the potential usage of high-accuracy climatic data measured continuously in the frame of newly developed renewable energy facilities in Romania for real-time local scale monitoring of climatic parameters, we used 2 years (May 2009 – May 2011) of in-situ climatic datasets measured at 7 met masts locations in Tulcea County. Realization of detailed thematic climatic maps afforded a more focused view of the spatial distribution and of the local patterns for air temperature, relative humidity and pressure, wind speed, direction and energy in the frame of the study site. On the basis of these preliminary results, we emphasize the great potential of similar in-situ real-time measured data to be integrated in the future, together with the data provided by meteorological stations, into complex databases. Their usefulness emerges from their capabilities of being integrated in specialized web-GIS platforms for real-time or near-real-time monitoring of small spatial scale climatic parameters and of contributing to climatic models calibration, weather forecasting, feeding early warning systems for local climatic hazards or to rapid small spatial scale assessment of air pollutants dispersal following different scenarios of wind speed and direction. Further research and initiatives are necessary in the near future for the creation and implementation of these databases in order to become operational.
