Resumen
This paper describes the results of the experiment to data the practices that the graphic designers follow to when developing a TDI (interactive digital text) if their previous experience has been only with printed publications. For the tests, the sample designers used the capabilities and interactive editing tools of the Adobe InDesign program and, based on the empirical results, a standardized model called MDA (Current Design Model) was formulated, from which one can identify the recurrent failures in the work process, which allows for pose possible solutions.Introduction: From the theoretical aspect, the methods for editorial design do not include the possibility of an interactive design. According to Jorge de Buen (2008) there are two methods for editorial design, additive and subtractive, none of these methods include what is being done in practice: the use of interactive features. "The interactive is defined by the capacity of participation on the part of the receiver, with the consequent modification of the original message, which is reconstructed according to the interests and interpretations of the last decoder; something that leads us to question the alteration of the idea of authorship. We refer to a new author-creator that is characterized by its plurality" (Caldevilla Domínguez, 2011). For the purposes of this experiment, TDI is defined as any text, whose message is transmitted through the combination of written language, animation, audio, video, links, and graphics, with the possibility of being used at will by the reader to complete the message, and not just as accompaniment. In this definition, the term "text" is preferred, which allows us to move from the book, journal and newspaper conceptions coming from the world of printed publications (Salinas, 2017). The lack of a specific method for the edition of TDI results in a practical problem: the designers adapt at will the additive or subtractive methods to produce TDI and although these adaptations can have successes, knowing how they solve the production of a TDI allows to identify the recurring errors.Method: 44 graphic design students were the case study in order to observe, gather and describe the current practices that graphic designers use in the development of TDI. They were asked to design and produce a TDI, using theoretical knowledge, the experience of having made at least one book and knowledge of the interactive capabilities of the Adobe InDesign editing program; after that, the instrument was applied for the collection of information.Results: A general work itinerary was identified that is represented by the MDA scheme (Current Design Model). This model is not a solution, but a representation of the current situation about the tasks developed by graphic designers when designing TDI without following a specific method for interactive design.Discussion or Conclusion: Using the MDA model, corrections to the work itinerary can be proposed, obtaining a method that considers the design of the interactive message, which induces the formulation of a method for TDI.

Resumen
Introduction: The work carried out through the use of a techno-pedagogical scenario is described, which is made up of the content of the subject of Applied Calculus in the Higher Level, the use of teaching and learning strategies (pedagogical work) and the use of technology. Specifically, we worked with an expert system called SIMAATCA, in which there are several multimedia resources to which students have access. It is intended to determine if with the employment of the techno-pedagogical scenario the students manage to improve their performance in one of the units of the curriculum (Unit 1. Applications of the Derivative) of the subject of Applied Calculus.Method: The research study was developed with two groups of 33 students each one, who were starting their second semester in the degree, one group was considered as the control one (GC) and the other was an experimental group (GE). In both groups the same Unit of the curriculum was approached, what differentiates the two groups is the teaching strategy used. In the control group was worked in a traditional way, using exclusively the blackboard and the textbook; while in the experimental group was worked with the techno-pedagogical scenario. The student's academic performance was measured by comparing the results obtained between the pretest and the posttest, both questionnaires applied to the two groups (control and experimental).Results: The results obtained in the diagnostic questionnaire (pre-test) both by the control group (CG) and the experimental group (EG) was very low since the students presented difficulties in the approaches of most of the problems. After having worked with both groups using different strategies, the post-test was applied. This time there was an improvement in the results obtained by both groups, but the EG excelled in the number of correct answers and the way to face each problem, compared to the CG.

Resumen
Introduction: The climate change consequences have been manifested on the environmental condition’s changes (temperature, rainfall, frost, drought, and soil salinity), then, the analysis of maize genetic diversity and their environment interaction is suggested. The objectives of this research were to determine the yield potential, the response to different environments of 63 maize landrace populations representative of the genetic variation in the southeast of Coahuila, Mexico.Method: The agronomic evaluation of native maize populations of eight racial groups was carried out in the spring-summer cycle in 2013 in two contrasted and representative locations of the environmental conditions in the southeast of Coahuila. Blocks were established independently within each location, and, in one location, blocks were different planting date. The blocks × location combinations were considered different environments to explore and make an interpretation of the genotype by environment interaction. In this paper, the response to the environment is analyzed based on grain yield and days to male flowering.Results: Eight populations were identified with an outstanding average yielding potential across environments, with values between 7.4 and 8.5 t ha-1, mainly representative from the Tuxpeño, Raton and Tuxpeño Norteño races. Populations adapted to transition-high altitude areas had an average yield reduction of 4.1 t ha-1 (55.0 %) after been exposed to intermediate altitude conditions.Discussion or Conclusion: The graphic interpretation of the genotype x environment interaction allowed to identify and to group the genotypes with specific adaptation in the environments of evaluation, as well as the ones with an average performance across environments. Twenty-two populations were identified with adaptation to transition- high altitude conditions, 14 to intermediate altitude areas and 27 populations with an average performance across environments.

Resumen
Introduction: Laelia autumnalis is an endemic orchid species from Mexico which is threatened by its habitat loss. In order to preserve this species disinfestation and adequate drying methods are necessary developed of cryopreservation and in vitro culture technics.Method: For a good long-term storage optimization the direct immersion technic in liquid nitrogen was considered in the first experiment (E1), however, asymbiotic germination was affected by the fungi Alternaria sp.; because of that, a second experiment was carried out with two assays in order to evaluate the seed viability and asymbiotic germination based on 1% (w/v) of calcium hypochlorite (CaCl2O2) and 15% (v/v) of commercial sodium hypochlorite (NaClO) as disinfection methods and using the air of laminar air-flow (A), silica gel (G) and vacuum pump (V) as drying methods before (E2) and after (E3) liquid nitrogen immersion (LN).Results: Viability was reduced in 49% and 37% by CaCl2O2 and NaClO, respectively, while A and V drying methods were caused the highest viability loss (36 and 28%), respectively. The loss of viability in E3 was lower than E2 and it was observed a stimulation by NaClO in germination (100%).Conclusion: These seeds must be disinfected with NaClO and dried using the air of laminal air-flow after cryopreservation by direct immersion in order to avoid plant tissues damage.

Resumen
Quantitative analysis of the architecture of the superior and inferior temporal retinal veins and their monitoring over time could facilitate the diagnosis and timely treatment of diabetic retinopathy. This paper presents a novel method consisting of two stages for automatic segmentation and parabolic modeling of the superior and inferior temporal arcade vessels in retinal fundus images. In the first stage, the Multiscale Line Detector (MLD) is used to detect vessel-like structures in the retinal images. Since the MLD, is a vessel enhancement method, a thresholding strategy has to be used to classify vessel and non-vessel pixels, where an experimental threshold value is compared with five state-of-the-art thresholding methods. In this stage, the proposed segmentation method is compared with six state-of-the-art specialized methods in terms of segmentation accuracy. In the second stage, a parabolic modeling using an optimization strategy based on the Univariate Marginal Distribution Algorithm (UMDA) is performed over the segmented vessels and the results are compared with two state-of-the-art parametric methods and with the ground-truth images outlined by specialists. The results of vessel segmentation using the multiscale line detector demonstrated a high segmentation accuracy with a 0.9618 value using the DRIVE database of retinal fundus images. In addition, the parabolic modeling results provided an average accuracy of 0.825 with the ground-truth of the superior and inferior temporal arcade vessels outlined by ophthalmologists. According to the accuracy and the computational time (5.62 seconds) results, the proposed method can be considered as highly appropriate to perform computer-aided diagnosis in Ophthalmology.

Resumen
Introduction: The transparent evaluation of projects proposals for scientific research with financial support through calls made by governmental institutions or private organizations becomes extremely important, along with increasing confidence in the researchers who participate in the calls for the allocation of financial resources. Therefore, this research presents an alternative to the process of evaluating projects with financial resources. The current method of evaluating funded projects is to obtain an average of the scores assigned to each project by a group of reviewers. However, this method does not discount the effect of the reviewer and produces a bias in the final evaluation of each project, since projects are likely to be favored when reviewers are relaxed and affected when reviewers are demanding and very strict. Method: This research proposes the use of two experimental design statistical methods for project evaluation: (a) incomplete balanced block design and (b) Alpha block design. In addition, we provide codes in the statistical software R, for both statistical designs, which allows us to implement project evaluation quickly and accurately. Results: Based on the proposed methods, it was found that the traditional method presents a very important bias due to the heterogeneity among the reviewers. Discussion and Conclusion: The use of experimental design statistical methods (balanced incomplete block design or Alpha design) can reduce this bias considerably, obtaining a higher accuracy for evaluations.

Resumen
The article analyzes, theoretically and empirically, the importance of competitiveness, which is the basis for a successful entry inside automaker´s market with a structure of monopolistic competition on global scale, such is the case of the Mexican automotive industry. The mentioned business sector is an example of constant changes in its market structure with the recent entry of Korean companies which are Hyundai and KIA motors. The results demonstrate that since the entry of KIA Motors in July 2015, there was some market deconcentration in the industry, leading it to become the fifth largest assembler in Mexico. The graphic analysis of market shares indicates that Hyundai is less successful than its partner brand (KIA). However, the econometric results indicate that the deconcentration of the market is associated to a greater extent with the growth of the Hyundai´s market share , as well as, the growth of smaller brands in its market quote that have longer time competing in Mexican market, comparing them to Korean companies such as Hyundai and KIA in Mexico. The results invites us to do a reflection on the classical assumptions about entry into a structure of monopolistic competition and its degree of concentration because it is commonly mentioned that entry of new competitors deconcentrates the market. However, if the rivalry increases, there will also be a bigger market deconcetration. It is concluded that in the Mexican automotive industry, the competitiveness and competitive strategy of brands (automakers), explain the concentration and performance of companies in this type of market.

Resumen
Introduction: Values are cultural elements that act as social glue; its analysis in the organization allows us to better understand the human being. Various models have been proposed. In this paper we return to Shalom Schwartz (2005) to analyze the relationship and hierarchical structure of desirable values, desired and practiced among university students and the meanings that students assign to these values, in order to provide explanatory frameworks of human behavior through the interaction between organization and individual. Method: The research was carried out in students of the School of Administrative Sciences of the University La Salle Morelia by means of a mixed technique that consisted in the application of a questionnaire to a probabilistic sample and later the data were analyzed with the help of natural semantic networks. Results: The results show a convergence of the practiced values with those of the institutional ideology; as well as, changes in the ordering as they advance in the career, so that the student moves from values mostly of personal promotion to those of transcendence. In addition, he always prefers openness to change over conservation. Discussion or Conclusion: The greatest differences are found between the desired and practiced values that can be explained by the meanings that students assign to each value, so it is verified that the operational definitions assigned to each value influence its hierarchical ordering.
