Percepción y significación de la gráfica urbana, en un acercamiento a la transdisciplinariedad

MARIA TERESA OLALDE RAMOS (2023, [Capítulo de libro])

Capítulo número 1 de la Sección El juego de los signos.

Se puede decir que los gráficos urbanos al ser analizados desde los distintos enfoques en que son interpretados, pueden ser entendidos como un fenómeno complejo, vistos desde su representación formal como signos, o también de acuerdo a su funcionalidad práctica como pueden ser las señales de tránsito, o bien los anuncios publicitarios y su impacto comercial que, como parte del contexto en que se ubican, pueden cambiar su sentido práctico y tomar nuevos roles de acuerdo a su significado. Estos mismos mensajes visuales pueden llegar a ser interpretados y significados como símbolos representativos de un sitio o como decoraciones escenográficas del mismo. Lo importante es entender es que todos y cada uno de los elementos visuales que encontramos en el contexto urbano comunican, ya que intrínsecamente llevan un mensaje en su propia representación visual, que a su vez son interpretados desde distintos enfoques por el sujeto con el que interactúan. El estudio transdisciplinario enriquecerá el conocimiento de la ciudad, lo cual puede ser un gran apoyo en la creación de distintas intervenciones en cuanto a la organización de espacios, desarrollo de edificaciones, de elementos mobiliarios, de transporte, así como de procesos de comunicación, las cuales se verán enriquecidas con los distintos enfoques disciplinarios que podemos encontrar en las diversas interpretaciones de los múltiples sujetos que la viven y la utilizan como parte de su cotidianeidad.

Data for the synthesis, characterization, and use of xerogels as adsorbents for the removal of fluoride and bromide in aqueous phase

NAHUM ANDRES MEDELLIN CASTILLO ELIZABETH DIANE ISAACS PAEZ Liliana Giraldo Gutiérrez JUAN CARLOS MORENO-PIRAJAN ITZIA RODRIGUEZ MENDEZ SIMON YOBANNY REYES LOPEZ JAIME REYES HERNANDEZ SONIA JUDITH SEGOVIA SANDOVAL (2022, [Artículo])

"Groundwater with high fluoride concentrations has been recognized as one of the serious concerns worldwide. Besides, the fluoride released into the groundwater by slow dissolution of fluoride-containing rocks, various industries also contribute to fluoride pollution [1]. Excess intake of fluoride leads to various health problems such as dental and skeletal fluorosis, cancer, infertility, brain damage, thyroid diseases, etc. [2]. On the other hand, bromide is naturally present in surface and groundwater sources. However, during the chlorination process, bromide can be oxidized to HOBr, which can react with natural organic matter in water to form brominated organic disinfection byproducts, which are very harmful to human health [3]. Among various methods for water treatment, the adsorption process has been widely used and seems to be an efficient and attractive method for the removal of many contaminants in water, such as anions, in terms of cost, simplicity of design, and operation [4,5]. In the past years, xerogels and carbon xerogels, a new type of adsorbents, which are synthesized by the sol-gel polycondensation of resorcinol and formaldehyde, have gained attention due to their moldable texture and chemical properties [6]. Moreover, melamine addition in resorcinol and formaldehyde xerogels adds basic groups on its surface, favouring Lewis acid-base interactions between xerogels and other components by adsorption [7]. In this data article, the synthesis of three resorcinolformaldehyde (R/F) xerogels with an increasing amount of melamine (M) was carried out by colloidal polymerization (molar ratios of M/R = 0.5, M/R = 1.0, and M/R = 2.0). Additionally, samples of M/R = 0.5 xerogel were carbonized at 400, 450, and 550 degrees C under an inert atmosphere to increase their specific area. Organic and carbon xerogels obtained were characterized by FTIR, TGA, SEM, Physisorption of N 2, and the pH at the point of zero charge (pH PZC). All organic xerogels were also tested as adsorbents on the removal of fluoride and bromide ions from aqueous phase. The Freundlich, Langmuir, and Radke-Prausnitz isotherm models were applied to interpret the experimental data from adsorption equilibrium. Additionally, the data of the mass of the xerogel needed to remove fluoride and bromide from groundwater and fulfill the maximum concentration levels are also included."

Structural analysis evaluationfor rollers of chassis dynoUsing finite element software

Jesús Emmanuel López Rizo ALFREDO CHAVEZ LUNA JAIME GONZALO SANTANA ESQUIVEL (2023, [Artículo])

This paper discusses the design considerations for a chassis dynamometer, focused on the rollers system used for measuring the power and torque of a vehicle in a university-level workshop. The design must prioritize factors such as safety, ease of use, adaptability to diverse types of vehicles, and the inclusion of safety systems to protect students and the vehicle. The work suggests adaptative features for the design, such as an adjustable fastening system and a compact and portable design, to adapt the structure into a university laboratory. The study also describes common methods for measuring engine power and torque using a chassis dynamometer, and the accurate and reliable measurement systems used for this purpose. This concludes with a discussion of the manufacturing methods used for the chassis dynamometer and a static analysis of the maximum effort capacity in each roller using Von Mises and Goodman fatigue theories. Developing a chassis dynamometer, in accordance the current patents available for workshop practices in a university is essential for providing students with comprehensive training.

Do provisioning ecosystem services change along gradients of increasing agricultural production?

Ronju Ahammad Stephanie Tomscha Sarah Gergel Frédéric Baudron Jean-Yves Duriaux Chavarría Samson Foli Dominic Rowland Josh Van Vianen Terence Sunderland (2024, [Artículo])

Context: Increasing agricultural production shapes the flow of ecosystem services (ES), including provisioning services that support the livelihoods and nutrition of people in tropical developing countries. Although our broad understanding of the social-ecological consequences of agricultural intensification is growing, how it impacts provisioning ES is still unknown. Objectives: We examined the household use of provisioning ES across a gradient of increasing agricultural production in seven tropical countries (Bangladesh, Burkina Faso, Cameroon, Ethiopia, Indonesia, Nicaragua and Zambia). We answered two overarching questions: (1) does the use of provisioning ES differ along gradients of agriculture production ranging from zones of subsistence to moderate and to high agriculture production? and (2) are there synergies and/or trade-offs within and among groups of ES within these zones? Methods: Using structured surveys, we asked 1900 households about their assets, livestock, crops, and collection of forest products. These questions allowed us to assess the number of provisioning ES households used, and whether the ES used are functionally substitutable (i.e., used similarly for nutrition, material, and energy). Finally, we explored synergies and trade-offs among household use of provisioning ES. Results: As agricultural production increased, provisioning ES declined both in total number and in different functional groups used. We found more severe decreases in ES for relatively poorer households. Within the functional groups of ES, synergistic relationships were more often found than trade-offs in all zones, including significant synergies among livestock products (dairy, eggs, meat) and fruits. Conclusions: Considering landscape context provides opportunities to enhance synergies among provisioning services for households, supporting resilient food systems and human well-being.

Structural violence against children in Chihuahua

Hector Castro-Loera Gabriela Orozco Lopez (2022, [Artículo, Artículo])

Within the framework of philosophy and its social function, structural violence against children in Chihuahua is studied; To approach the phenomenon and propose alternatives, three theories will be related: i) feminist studies regarding violence, concepts such as intersectionality, pedagogies of cruelty and structural violence will be used, ii) the philosophy of children's rights, child´s play will be appreciated as a necessity and legal position of freedom, and iii) the event of the Aufklärung, that is, the assimilation of the present of humanity or the Enlightenment in Foucault's thought.

Determinantes del comportamiento de queja del consumidor en México

Determinants of consumer complaint behavior in Mexico

IGNACIO JAVIER CRUZ RODRIGUEZ JAVIER GALAN FIGUEROA (2019, [Artículo])

El objetivo del trabajo es explicar los determinantes del comportamiento de queja del consumidor en los niveles socioeconómico y empresa. Para ello se acude a la metodología de datos de panel estático a fin de estimar el impacto de los determinantes de las quejas de los consumidores. Los resultados a nivel socioeconómico indican que las quejas se encuentran determinadas por el ingreso, las conciliaciones a favor de los consumidores y por la población residente en zonas urbanas. Mientras a nivel empresa los resultados muestran que tanto la cuota de mercado como el tamaño de la firma afectan positivamente las quejas. Se concluye que los resultados coinciden con la literatura revisada y que se puede esperar un aumento en el número de quejas presentadas por los consumidores.

This work aims to quantify the determinants of consumer complaint behavior in socioeconomic and business levels. For this purpose, the static panel data methodology is used in order to estimate the impact of consumer complaints both at the federal level of the Mexican Republic and at the level of the main companies that are considered leaders in their field. The results by the state indicate that the complaints are determined by income, reconciliations in favor of consumers and population residing in urban areas.While at the company level, the results show that both market share and company size positively affect consumer complaints. In conclusion, the results agree with the literature reviewed, and a rise in the number of complaints is possible.

INFLUENCIA DE CONDICIONES AMBIENTALES SOBRE LA DISTRIBUCIÓN, ABUNDANCIA Y DESARROLLO DE LARVAS DE Totoaba macdonaldi (Gilbert, 1890), EN EL ALTO GOLFO DE CALIFORNIA

Marcelo Vidal Curiel Bernal (2023, [Tesis de doctorado])

"La presente tesis aborda una investigación sobre la biología, ecología y crecimiento de la Totoaba macdonaldi en el alto golfo de California. La totoaba, una especie endémica a esta región se encuentra actualmente en peligro de extinción debido a una serie de amenazas como: cambios en su ecosistema reproductivo y de crianza, pesca, incidental de juveniles e ilegal de adultos. Aunque en los últimos 30 años la población dio signos de recuperación, existen indicios de que tanto la población adulta como las abundancias de larvas presentan una tendencia decreciente. Lo que resalta la importancia de estudiar cómo la variabilidad ambiental incide en la distribución y abundancia de larvas de totoaba y subsecuentemente en el stock recluta de la especie. El estudio comienza con un análisis de la variabilidad del crecimiento individual en etapas juveniles y adultas de la totoaba. Para este propósito, se utiliza la varianza observada como elemento clave para parametrizar modelos de crecimiento individual. Los resultados indican que este enfoque proporciona estimaciones sólidas de los parámetros de crecimiento. A continuación, se investiga el crecimiento de las larvas de totoaba en condiciones de cultivo. Los datos revelan que un modelo sigmoideo describe mejor el crecimiento y se identifican dos puntos de inflexión en el crecimiento de las larvas. Estos hallazgos tienen importantes implicaciones para la cría y el cultivo de la totoaba para efectos de repoblación. Por último, se analiza la ecología y el transporte de las larvas de totoaba en el alto golfo de California. Se identifica una ventana óptima para el desove de la totoaba en términos de temperatura y concentración de clorofila, y se sugiere que las condiciones ambientales y la distribución de los adultos pueden influir en las abundancias de larvas en diferentes años. Además, se destaca la importancia del frente permanente al sur del alto golfo de California como una posible zona de acumulación de larvas como factor que contribuye al endemismo en la región. En conjunto, esta tesis representa un enfoque multidisciplinario para comprender los aspectos clave de la biología, ecología y crecimiento de la totoaba en el alto golfo de California. Los resultados proporcionan información valiosa para la conservación de esta especie amenazada y destacan la importancia de un enfoque integral en la gestión de los recursos marinos en esta región única."

"The following thesis addresses a research on the biology, ecology, and growth of Totoaba macdonaldi in the upper gulf of California. The totoaba, a fish species endemic to this region, is currently endangered due to a series of threats such as: changes in its reproductive and breeding ecosystem, juvenile bycatch, and illegal fishing. Although over the last 30 years, the population has shown signs of recovery, there are indications that both the adult population and larval abundances are on a declining trend. This underscores the importance of studying how environmental variability affects the distribution and abundance of totoaba larvae and subsequently the recruitment stock of the species. The study begins with an analysis of growth in juvenile and adult stages of the totoaba. For this purpose, observed variance is used to parameterize individual growth models. Results indicate that this approach provides robust estimates of growth parameters. Next, the growth of cultivated totoaba larvae is investigated. The data reveal that a sigmoid model better describes the growth in the early life stages of the totoaba, and two inflection points in larval growth are identified. These findings have important implications for the breeding and cultivation of the totoaba for restocking purposes. Finally, the ecology and transport of totoaba larvae in the upper gulf of California are analyzed. An optimal window for totoaba spawning in terms of temperature and chlorophyll concentration is identified, and it is suggested that environmental conditions and the distribution of adults may influence larval abundances in different years. Additionally, the importance of the permanent front to the south of the upper gulf of California is highlighted as a possible larval accumulation zone and a contributing factor to endemism in the region. Overall, this thesis represents a multidisciplinary approach to understanding key aspects of the biology, ecology, and growth of the totoaba in the upper gulf of California. The results provide valuable information for the conservation of this threatened species and underscore the importance of a comprehensive approach in the management of marine resources in this unique region."

Using Observed Residual Error Structure Yields the Best Estimates of Individual Growth Parameters

Marcelo Vidal Curiel Bernal EUGENIO ALBERTO ARAGON NORIEGA MIGUEL ANGEL CISNEROS MATA LAURA SANCHEZ VELASCO SYLVIA PATRICIA ADELHEID JIMENEZ ROSENBERG ALEJANDRO FRANCISCO PARES SIERRA (2021, [Artículo])

"Obtaining the best possible estimates of individual growth parameters is essential in studies of physiology, fisheries management, and conservation of natural resources since growth is a key component of population dynamics. In the present work, we use data of an endangered fish species to demonstrate the importance of selecting the right data error structure when fitting growth models in multimodel inference. The totoaba (Totoaba macdonaldi) is a fish species endemic to the Gulf of California increasingly studied in recent times due to a perceived threat of extinction. Previous works estimated individual growth using the von Bertalanffy model assuming a constant variance of length-at-age. Here, we reanalyze the same data under five different variance assumptions to fit the von Bertalanffy and Gompertz models. We found consistent significant differences between the constant and nonconstant error structure scenarios and provide an example of the consequences using the growth performance index _0 to show how using the wrong error structure can produce growth parameter values that can lead to biased conclusions. Based on these results, for totoaba and other related species, we recommend using the observed error structure to obtain the individual growth parameters."
