Modeling the Effects of Interactions between Environmental Variables on the State of an Environmental Issue: The Case of the Morelos State in Mexico  [PDF]
Fernando Ramos-Quintana, Deny L. Hernández-Rabadán, Enrique Sánchez-Salinas, María Laura Ortiz-Hernández, María Luisa Castrejón-Godínez, Edgar Dantán-González
Journal of Environmental Protection (JEP) , 2015, DOI: 10.4236/jep.2015.63023
Abstract: An important use of environmental indicators is oriented to know their individual impact on the whole environment quality. Nevertheless, most of the important causes of environment affectations are derived from multiple interactions between indicators which correspond more specifically to the environmental reality. The affectations derived from interactions should be analyzed and interpreted through numerical expressions representing a relevant challenge for developers of environmental indicators. To cope with the analysis and interpretation problem, we propose in this work a methodology in two senses: in a bottom-up sense a directed graph is built representing interactions between environmental indicators as behavioral relations, which exert an effect on the state of an environmental issue of a site over time (10 years); in a top-down sense to assist users in the analysis and interpretation of interactions through a computer interface that provides users with the capacity of knowing how and what relational behaviors between indicators are affecting, the most or the least, the performance of the environmental issue being studied. This methodology was applied to the analysis an interpretation of interactions between environmental variables that affect the state of an environmental quality issue related with the State of Morelos in Mexico. The results showed the adequate expressivity of a directed graph to represent interactions allowed to verify the coherence of the numerical values associated with their behaviors during a period of time and with their effects on the environmental issue under study.
Incorporation of Environmental and Sustainable Indicators in Universities  [PDF]
Lourdes Ruiz
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76075

The use of environmental and sustainable indicators of global organizations has greater advantages than those of national initiatives or those developed by researchers in said subject, due to the fact that they have a much broader scope for sustainability, have been applied in a systematic manner and therefore have greater comparability and reliability. The environmental indicators are constructed from the approaches to sustainable development in universities with regards to the social, economic, institutional and environmental dimensions in the organizations. This work involves the application of environmental and sustainable indicators for internationally recognized efficiency in university activities, which contribute towards organizing, summarizing and developing the processes for development planning and environmental management.

Effect of Recreation on the Species Richness and Diversity of Rotifers in Ponds  [PDF]
Ewa Skowronek, Anna Cudak, Irena Bielańska-Grajner
Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.49091
Abstract: Planktonic rotifers were examined from April to October 2007 in two ponds created by sand extraction: Hubertus III (infrequently used for recreation)—pond I and Stawiki (commonly used for recreation)—pond II. The ponds are located within the protected Landscape Complex “Szopienice-Borki” in Silesian Upland (SW Poland). A total number of 58 taxa of rotifers were noted. The number of rotifer species and their densities were smaller in pond I than in pond II. In pond I, Polyarthra species were the most abundant, accounting for 48% of total rotifer density, whereas in pond II, Keratella cochlearis reached the highest density (accounting for 36% of total density). Analysis of variance (ANOVA) revealed a significant difference between communities of rotifers in species diversity (F = 5.88, p = 0.02) and species richness (F = 5.57, p = 0.03). The research proved that the pond commonly used for recreation (pond II) is characterized by a higher trophic state. Results of this study indicate that the methods and range of use of water bodies by humans have an important influence on the species richness and diversity of communities of planktonic rotifers.
Indicators of Energy Efficiency in Buildings. Comparison with Standards in Force in Argentina  [PDF]
María Belén Salvetti, Jorge Czajkowski, Analía Fernanda Gómez
Open Journal of Energy Efficiency (OJEE) , 2013, DOI: 10.4236/ojee.2013.24021

In this work we make a comparative study of the energy behaviour in different building types. We analyze three cases of office buildings and three residential buildings, and compare them with a previous sample. We seek to find correlations or differences in behavior in terms of potential energy losses and gains, and UL values compared with Argentinian Standards to verify the degree of efficiency. For energy analysis we used a software which allows the analysis of thermal and energy building performance at steady state on a monthly basis. This software is called EnergoCAD and it also determines formal indicators based on IRAM standards. We conclude that the indicators used are clear to energetically grade buildings and to facilitate comparisons. In turn, smaller buildings are relatively less energy efficient than larger ones. At the same time it is noteworthy that the energy inefficiency has been growing rapidly over the years. Finally it is noted that none of the cases analyzed meets the National Standards.

Indicators Benchmarking of Cement-Based Construction Technologies: Brazilian Case Study  [PDF]
Alberto Casado Lordsleem Júnior, Bárbara Eloá Gon?alves de Lima
Open Journal of Civil Engineering (OJCE) , 2014, DOI: 10.4236/ojce.2014.44025
Abstract: The adoption of performance indicators promotes knowledge of quantitative and qualitative material wastes in businesses and, when inserted in a collaborative process, provides a comparative evaluation of results between companies and, thereafter, an identification of best practices (bench-marking). The purpose of this paper is to present the best practices identified by performance indicators, related to the measurement of wastes and associated to construction companies participation in the benchmarking research process “Implementation of a system of performance indicators of cement-based construction technologies of the Community of Construction of Recife city in Brazil-PROGRIDE”, coordinated by the Brazilian Association of Portland Cement-ABCP. Therefore, it was sought to characterize best practices that led to the benchmarking of performance indicators related to the wastes of concrete, industrialized mortar for masonry settling and blocks/ bricks. As a contribution, a set of factors that characterize the best practices for each technology and conducted to benchmarking were identified.
Social Vulnerability Index: A Methodological Proposal for Application in the Cities of Barra do Garcas—MT, Pontal Do Araguaia—MT and Aragarcas—GO, Brazil  [PDF]

Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.412004
Abstract: The concept of vulnerability is intrinsically attached to the risks that can affect the balance of life in countless ways. Thus, this paper aimed to determine the sites that present social vulnerability levels in the urban context of the municipalities of Barra do Garcas—MT, Pontal do Araguaia—MT and Aragarcas—GO. The social vulnerability index was calculated using a set of 23 indicators, arranged in 05 subjects: Conditions of breadwinners, family conditions, housing conditions, urban infrastructure and economic dimension. Then these results were inserted in the geographic information system through ARCGIS program for spatial representation of social vulnerability levels. It was found that the social vulnerability indices found for the study area were very low, low and medium, which did not show a very critical situation. In Pontal do Araguaia—MT was found low level of vulnerability. In contrast, in Barra do Garcas—MT, the sectors with greater social vulnerability are located in the western part of the city, which includes neighborhoods with lower family income, and lack of infrastructure. Regarding the Aragarcas city was noted that the socio-territorial segregation of vulnerability is more evident, and the sectors with medium index of vulnerability are located more on the outskirts of the city. The proposed methodology was effective and the socio-economic dimension has been well addressed, which is a diagnostic path that can be used to search for a more efficient urban development through specific public policies, which in turn will increase the resilience of the population involved.

Abstract: population urbanization is a global trend, and socioeconomic activities in urban areas cause changes that affect the environment and human well-being beyond the specific territories, thus connecting urban to non-urban areas and creating city-regions. this article's objective, from an ecosystem perspective, is to gather a set of information on municipalities (counties) belonging to the middle paraíba river valley region in the state of rio de janeiro, brazil, in order to identify conditions and trends in environmental sustainability and well-being. the conceptual framework adopted here was that of the millennium ecosystem assessment, identifying direct and indirect driving forces that affect human well-being, with health as a component of the latter. we used a set of available public-domain data and information sources on the municipalities, grouped by socioeconomic and environmental conditions and the soundness of institutional structural well-being for sustainability. the indicators used here point to a process of degradation in the ecosystem services that has still not been prevented by the prevailing institutional structure, thus increasing constraints on well-being and the spread of socio-environmental impacts in the middle and long terms.
Statistical Indicators System regarding Religious Phenomena
Claudiu Herteliu
Journal for the Study of Religions and Ideologies , 2007,
Abstract: The approaching ways in religious phenomenon quantitative studies are, most of the times, based only on the evolution of adherent flows and population structure from a religious point of view. In this pape, an integrated statistical indicators system will be designed. The main purpose of the system is to enhance the quality and coherence of the religious phenomenon. The most important indicators from the integrated system are: context indicators (political, economical, socio-cultural, demographical), basic indicators, level and structure indicators, participation indicators, resource indicators (spiritual, human and pecuniary), quality, efficiency and outcomes (religious freedom, social connections, international relationships). Designing a complete, coherent system of indicators is necessary for a correct approach in studying the religious phenomenon. Statistical indicators can supply quantitative data for the operational description of the religious phenomenon. The indicators’ system makes possible not only a descriptive analysis but also some advanced statistical techniques (e.g. regression and correlation method).
Agricultura sustentável III: Indicadores
Costa,Ana Alexandra Vilela Marta Rio;
Revista de Ciências Agrárias , 2010,
Abstract: the sustainability indicators, alone or integrated into complex models, constitute the instrument of sustainability assessment usually found in literature and applied empirically. the found procedure to identify the indicators and its measurement has, however, lead to some relevant issues, jeopardizing the value retrieved and the sustainability evaluation developed. in this sense, some considerations concerning the development of sustainability indicators are presented, that can justify the conclusion about the infinity of indicators that are liable to identify in different methodologies for sustainability assessing, as well as the limitation of criteria used in the occasion of their selection and measurement, despite the long list of cautions that can be encountered in various documents on the subject.
