The Effects of Tourism Architecture on Island Ecosystems  [PDF]
Lourdes Ruiz
Journal of Building Construction and Planning Research (JBCPR) , 2015, DOI: 10.4236/jbcpr.2015.34016
Abstract: This research aims to propose environmental prevention and mitigation on fragile coastal ecosystems due to the actions of the tourist architecture, using methods of life-cycle assessment of buildings, matrix methods of the actions that cause severe environmental impact and statistical processing through multivariate analysis. A study of projects was undertaken in Cayo Coco located to the north of Ciego de Avila, Cuba, being built today and where the tourist development of the archipelago Sabana-Camaguey started. It has been determined that suitable architecture would decrease the negative impact of these fragile ecosystems.

Lourdes Ruiz
Journal of Building Construction and Planning Research (JBCPR) , 2016, DOI: 10.4236/jbcpr.2016.41005
Abstract: The aim of this study is to apply the methodology for assessment of environmental impact whether of a physicochemical nature and on the biodiversity and ecosystems, or whether sociocultural and economic aspects of the historic towns with tourism interest that are assessed. The automated method of the RIAM software is used which requires a baseline study of the environment of different towns to be prepared. In addition, the analysis of the social perception on tourism of the local people from the course work of students at the UIDE shall be applied. The conclusions of the case studies undertaken allow for strategic proposals and recommendations to be prepared so that they can be incorporated into the management plans for tourism in the historic towns with heritage value.
Incorporation of Environmental and Sustainable Indicators in Universities  [PDF]
Lourdes Ruiz
Journal of Environmental Protection (JEP) , 2016, DOI: 10.4236/jep.2016.76075
Abstract:

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.

Adverse Environmental Effects of Tourism on Communities in the Ecuadorian Highlands Region  [PDF]
Lourdes Ruiz
Current Urban Studies (CUS) , 2017, DOI: 10.4236/cus.2017.53019
Abstract: The objective of this study is to determine the adverse environmental effects of tourism activities on various heritage populations located in the sierra or Andean highlands region of Ecuador. The effects being studied have been classified into impacts on the physical, abiotic, biotic, socio-culture and economic environment. The automated method using RIAM (Rapid Impact Assessment Matrix) software was employed in this analysis, which required the preparation of a baseline study in the small communities evaluated. A social perception survey was conducted of local residents regarding tourism, assisted by International University of Ecuador students fulfilling practical coursework requirements. Based on the conclusions of the case studies, some strategic proposals and recommendations were developed that can be incorporated into sustainable tourism management plans in communities with natural and cultural heritage values.
Using an Interactive Computer System to Support the Task of Building the Notions of Ratio and Proportion  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2010, DOI: 10.4236/ce.2010.12017
Abstract: This article describes the design and general outcome of applying a computer system that includes interactive activities to the topics of ratio and proportion. The work was undertaken with Mexican students attending primary school grade six (11 year olds). In designing the activities, our work was based on the studies of researchers who have focused on such topics, as well as on the work of researchers in the field of computer sciences and education technology. Support of the activities designed is found in psycho-pedagogy, in knowledge of mathematics and in the fields of computer sciences and education technology.
Representation Registers in the Solution of Calculus Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23036
Abstract: This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico). The article reports on the problems found among Engineering students with respect to their resistance to using different representation registers when solving optimization problems in the Calculus Learning Unit. Use of such registers could help the students to build mathematics know ledge and to solve calculus problems. As a didactic strategy, simulations are used in an electronic environment in order to support the students by fostering their use of tabular, graphical and algebraic representation registers. Interviews are undertaken of six of the professors who give the calculus courses, and a diagnostic questionnaire is applied to 68 students prior to and after working with the proposal. As for the theoretical framework, the work reported by Duval and Hitt is salient in this report, particularly their emphasis of the fact that working on activities by way of one single representation system is not sufficient. From the first responses provided by the students, one can conclude that the algebraic register is preferred by the majority of students. It is however used in a mechanical fashion without affording any meaning to the content of the problem and to the process of solving it. Another conclusion reported is that implementing tasks in the classroom in which the mathematics activity requires coherent use of different representations is necessary.
Primary and Secondary Teachers’ Knowledge, Interpretation, and Approaches to Students Errors about Ratio and Proportion Topics  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23035
Abstract: This study investigated elementary and secondary teachers’ understanding and pedagogical strategies applied to students making errors in finding a missing length in similar rectangles. It was revealed that secondary teachers had better understanding of ratio and proportion in similar rectangles than elementary teachers. While all secondary teachers solved the similar rectangles problems correctly, a large portion of elementary teacher struggled with the problem. In explaining their solution strategies, and even though similar strategies appeared both from elementary teachers and secondary teachers, a majority of secondary teachers pointed out the underlying idea of similarity, whereas less than half of the elementary teachers explained their reasoning for using ratios and proportion. This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico)
A Cognitive Analysis When the Students Solve Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34063
Abstract: The research reported in this paper shows an analysis of the cognitive process of students from the senior technical program on food technology, whom are asked to solve a contextualized event on systems of linear algebraic equations within the context of balance of matter in situations of chemical mixtures. The cognitive analysis is founded on the theories of Conceptual Fields and vents. For the analysis attention is focused on the representations carried out by students regarding the invariants in the schemes that they build when they face an event of contextualized mathematics. During the acting process of students emerge different types of representation which are appropriate to the context in which the research develops, with which a proposal for the classification of them.
Econographication  [PDF]
Mario Arturo Ruiz Estrada
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.45036
Abstract:

The rationale of Econographication revolves around the efficacy of multidimensional graphs as the most effective visual tool to understand any economic phenomenon from a multidimensional view. The main motivation behind the creation of Econographication is to evaluate multidimensional graphs evolved so far in economics and to develop new type of multidimensional graphs to facilitate the study of economics, as well as finance and business. Thereby, the mission of Econographication is to offer academics, researchers and policy maker’s an alternative multidimensional graphical modeling approach to the research and teaching-learning process of economics, finance and business from a multidimensional perspective. Hence, this alternative multidimensional graphical modeling approach is offering a set of multidimensional coordinate spaces to build different types of multidimensional graphs to study any economic phenomenon. The following new types of multi-dimensional coordinate spaces are presented: the pyramid coordinate space (five axes and infinite axes); the diamond coordinate space(ten axes and infinite axes); the 4-dimensional coordinate space (vertical position and horizontal position); the 5-dimensional coordinate space (vertical position and horizontal position); the infinity-dimensional coordinate space (general approach and specific approach); the inter-linkage coordinate space; the cube-wrap coordinate space; the mega-surface coordinate space. All these multi-dimensional coordinate spaces mentioned previously, they are available to represent graphically 4-dimensions, 5-dimensions, 8-dimensions, 9-dimensions until infinity-dimensions.

The Global Dimension of the Regional Integration Model (GDRI-Model)  [PDF]
Mario Arturo Ruiz Estrada
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.45037
Abstract:

This research paper presents a new model of analysis to study the trend of regional integration from a global perspective. This new model is called the Global Dimension of Regional Integration Model (GDRI-Model). The rationale for the creation of this model is the necessity to study regional integration from political, social, economic, and technological perspectives simultaneously. There are four basic phases in the implementation of the GDRI-Model. The first phase is the design of the multi-input database table. The second phase is the measurement of individual Regional Global Development Indexes (Xi), which include the Regional Global Political Development Index (X1), Regional Global Social Development Index (X2), Regional Global Economic Development Index (X3) and Regional Global Technological Development Index (X4). The third phase is the measurement of the Regional Global Development (RGD) index. The last phase is the measurement of Regional Integration Stage (RIS) index. The general objective of the GDRI-Model is to offer policy-makers and researchers a new analytical tool to study the evolution and stages of any regional integration process from a global perspective—based on a group of indexes and graphs. The GDRI-Model is not intended to be a forecasting model in any case. However, its application is not limited to the study of a special group of countries or regions. It is not constrained by issues about the region or the development stages of any member in a region that is interested in integrating into a single regional trade bloc. The GDRI-Model, in effect, is a simple and flexible scheme, which can be applied to any case of regional integration.
