Introduction. Computation of matrix pseudospectra is required in many applications when modeling by differential equations. This computation is really expensive, especially for large matrices, for which highly parallelizable algorithms have been successfully implemented on high performance computers. Objective. We present an exploratory analysis of the pseudospectra computation in a hybrid architecture CPU-GPU where the graphics processing unit performs the massive parallel computation. Methodology. A proposal is formulated after analyzing some parallel implementations on high performance computers, methods based on Krylov methods, and the capacities of the graphics processor units for massive computation in the large-scale setting. Results. The proposal is attractive since the graphics processing units currently can be found on a wide range of computers, or can be adapted to any computer at a very a low cost. Conclusions. In this document we describe a general scheme for the parallel computation of pseudospectra on a hybrid architecture CPU-GPU.

Introduction. Within the organizational dynamics, multiple relationships are displayed characterized by the culture of that work space, one of the most important relationships is the one established between the workers and the factors that determine their performance. Hence, these factors are identified as the variables that influence the work behavior of employees and consequently intervene in the quality of work, considering that a problem could appear if these factors negatively affect the work performance of workers and affect the quality of the final product. Objective. Analyze job performance and the performance of workers related to the quality of civil construction works within the Autonomous Decentralized Municipal Government (GADM) of Pucará. Methodology. The qualitative, non-experimental approach was used, with a descriptive and cross-sectional scope. It is a field investigation because the information was obtained directly from the workplace where the problem situation occurs, a survey was designed in questionnaire format, structured by 10 items to be applied to 16 construction foremen and 15 construction assistants. Results. They indicated that there are factors within the GADM of Pucará that positively determine the product of civil works. Observing respect and acceptance of regulations, adequate interpersonal relationships based on companionship. Also, there are aspects that can be improved such as schedules, remuneration and construction training. Conclusions. It was shown that the factors that determine job performance can enhance or negatively affect this performance.

The increasing levels of competition in the tourism sector today and some more experienced and demanded tourists, force hotels managers to apply judgments of greater professionalism in the management of their establishments, and to pay particular attentionto the satisfaction of the customer needs and to the detection and identification of market opportunities that may arise. This study proposes the identification of the Hotel Santa Isabel´s competitors, by studying its position in the market. To accomplishthe definition of the competitors, a change of approach of the positioning studies was made, starting from the design of a perceptual map or market positioning map. The change of approach was given under the conditions of considering a competitor of an establishment, to that company that delivers the same attributes to the same market segment in a similar way. As a result, was determined the main competitor of the Hotel Santa Isabel, based on its location on a three-dimensional positioning map and the distance in relation to the rest of the hotels studied, demonstrating the usefulness of this tool for identifying competitors.

Introduction. Meat consumption trends; the way it is produced and marketed is changing worldwide. In this sense, Ecuador has not been the exception, and particularly the province of Chimborazo where both the production and consumption of this food has undergone changes. On the other hand, the issue of health, environmental awareness are some of the factors that have influenced the consumption of this protein and that also merit an analysis. The objective of the research proposes a theoretical approach to the analysis of the production and consumption of meat in the province of Chimborazo in order to serve as a baseline and contribution for future investigations that wish to deepen the subject, as well as guide future commercial decisions and of production within the province. Methodology. The research design is qualitative-quantitative and cross-sectional. The methods used were the historical-logical, inductive-deductive, analytical-synthetic. Results. Among the most significant results, it can be highlighted that almost half of the cattle destined for meat production are found on the Coast, while dairy cattle are concentrated in the Sierra. Chimborazo represents only 6% of livestock production compared to the other provinces. Conclusions. One of the main conclusions is that factors such as health, price, product presentation and ecology affect the consumption of red meat.

This case study addresses as a scientific problem from the socio-technical, the current limitations of educational and pedagogical communication as science and knowledge. The object of the case study focuses on the distribution, function and social use of technology to the understanding of the educational communication strategy, aimed at the work of sociocultural and community management in the Integral Transformation Workshop of the Neighborhood (TTIB-Canal) of the Cerro Municipality. The general objective is therefore: Explain the main factors that currently limit or hinder the distribution, function and social use of technology to the understanding of the educational communication strategy, aimed at sociocultural and community management work in the Workshop on Integral transformation of the Neighborhood (TTIB-Canal) of the Cerro Municipality, as specific: Make a socio-technical approach to the educational communication strategy directed to the work of sociocultural and community management in the TTIB-Canal of the Cerro Municipality. Determine the limitations that are presented in the educational communication strategy, aimed at sociocultural and community management work in the TTIB-Canal of the Cerro Municipality. Define the social impacts that are generated or not from the socio-technical point of view from the interaction of the strategy and describe its elements.

Sociocultural and community management has been defined, from a socio-technical approach as systems of strategic socio-technical processes through which the knowledge and socio-cultural and community practices of the community are legitimized as living heritage, they are assumed as identity value of the community and its transformative potentialities are channeled in negotiation contexts. It is considered that the current limitations of this cultural management are influenced by three types of determinants or factors, mainly the epistemic, technological and cultural-communicological factors.

The use of strategy and planning dates back to the dawn of mankind, the first inhabitants relied on it for the development of their first tasks; activities related almost entirely to war but managed to develop this practice over the years. Already in modern times, planning became the foundation of business success of the companies of the twentieth century; however, with the passing of time, the development of this administrative tool has not only not lost its validity, but on the contrary, in a highly complex and competitive world, it is necessary to take firm and safe steps that enable an adequate use of resources and promote the fulfillment of organizational objectives. The present study sought to find the relationship between the theory of strategic planning and its support in the results of Ecuadorian companies that have been recognized for their work, and that in their official means of communication state that they use strategic planning as the basis of their success. An exhaustive bibliographic review made it evident that despite the years, the formulation of planning and its adequate implementation guide the achievement of organizational objectives.

Introduction. The ancestral knowledge allows living and immortalizing the customs, uses and traditions that the ancestors have left through time in the communities of Ecuador. The ancestral ethno-knowledge of the Shuar community located in the province of Pastaza, northeast of the Amazon region is extraordinarily rich and varied. Methodology. Data collection was done through participatory workshops, surveys, and expeditions in the study area. Objective. The purpose was to collect plant species and identify them in situ, always accompanied by local people considered to have experience and knowledge of their territory. Results. A total of ten species of flora that are part of the traditions and culture of the community were recorded, from which it was concluded that ayahuasca followed by cat's claw are the representative species and that the forest is the main source of food, medical supplies, rituals, music, handicrafts, construction, celebrations, etc. Conclusions. The importance of tourist architecture lies in the design of community ancestral tourist houses with low environmental impact thanks to the use of raw material extracted from local plants for its construction, has allowed to have adequate spaces for demonstrations of ethnobotanical knowledge where the intercultural connection between the shaman who has the ancestral heritage with its physical - natural and cultural - religious - spiritual environment, allowing the tourist to eliminate elements that cause the evil that suffers, ethnobotanical knowledge of the Shuar community that have great acceptance by domestic and foreign tourists.
