Authors: KASPERCZYK Damian , BARBUSIŃSKI Krzysztof , KOZIK Violetta
Published: September 2018

The study presents the preliminary results of research with the aim to test a Compact Trickle-Bed Bioreactor (CTBB) to the biopurification of air from VOC’s mixtures (ethyl alcohol, dimethyl sulphide, styrene). The experiments were performed using a 45 dm3 semi-industrial scale bioreactor in which gas and liquid phases flowed co-currently in downward direction through a bed made up of polyethylene rings. The bioreactor was inoculated with a co-culture of microorganisms including bacterial strains found in the wastewater and adopted to chosen pollutants. The gas-flowrate was 4.0 m3/h and VOC concentration in the gas phase was changed from 40 to 255 ppm. In the whole period of research the efficiency of pollutant removal was in the range 92-99%. The lowest result of efficiency was achieved in the 2nd day of research as a response of the highest concentration of VOC. Possible consequences of a violent pollutant overload and the time required for regenerating the microorganisms and returning to the stable process conditions were also investigated. An increase of VOC concentration to 220-255 ppm did not significantly influence the deterioration of process efficiency. After the period of adaptation of microorganism to the process condition and immobilization of microflora on the packing material, the experimental set-up has been working reliably for 21 days.
Between Architecture And Art. The Space of Aquaintance
Authors: MIZIA Małgorzata
Published: September 2018

The article is based on the definition of architecture as an art of shaping space (B. Zevi), comparing it to the art of sculpting, and the concept of sculpting-ness which refers to spatial effects and the creative/artistic character of the designing. The wrapping space of architecture has been treated as a non-material virtual sphere of information exchange. It is a space of mutual communication of: knowledge, skills, art and poly-sensory perception of the recipient. Similar selected phenomena concerning architecture and other arts have been compared. The result points to a common nature of the phenomena in spite of their diametrically different uses. It also points to their identical character respectively in the spheres of: creation, notation, and realization of goals within the individual arts. Additionally the scale and protective character of architecture endow this art with a special utilitarian function which is superior and irreplaceable in human life. The whole article has been treated as a description of earlier research.

Authors: SZTUBECKI Jacek , MRÓWCZYŃSKA Maria , SZTUBECKA Małgorzata
Published: September 2018

Weirs are civil engineering structures designed to dam up the stream of water. They are often very old structures subject to preservation care. In order to maintain the level of ground water, it is essential to keep them in good repair. Therefore, weirs require monitoring of their technical condition and geometry.

This article contains an elaboration of the results of measurements of the geometry of a steel cylinder which is a major component of the historical weir Czersko Polskie in Bydgoszcz. The spatial layout and the geometry of the cylinder were determined on the basis of results obtained from measurements referenced to selected points located on its surface, downstream of the dam. The availability of the cylinder surface for the measurements was limited to the visible part, downstream of the structure. Nevertheless, using the adopted calculation procedure it was possible to determine the position of the cylinder axis as well as the twisting and deformation of the cylinder surface.

Taking Up Residence Near The Garden As The Substitute Of The Garden-City Idea The housing development and spatial structure of the suburban areas as the combination of ignoring a place context and a myth of living in the garden-city on the example of the buffor zone of the Łagiewnicki Forest in Łódź
Authors: Krzysztofik Sylwia
Published: September 2018

Garden city is an idea regarded as one of the reasons for the spontaneous sprawl of buildings around the city. The paper compares the assumptions described in the book “Garden Cities of Tomorrow” with the way of the investment implementation on the outskirts of Łódź, in the buffer zone of the Łagiewnicki Forest. The analysis of the spatial structure of the newly urbanized open areas, made on the basis of aerial photography and introduction of geodesic division shows that the emerging housing development is not being inspired by the idea of the garden city. The newly urbanized areas are being built up in any manner without designed spatial composition, road system and public transport system and ignoring the use of landscape. The suburban housing emerges as individual investments, inhabitants of urban sprawl are not active in the life of local communities. The current situation requires the creation of effective urban planning doctrine. The guidelines described by Howard may serve as an inspiration for improving the quality of space in suburban areas, providing urban standards which are used require a quality space while implementing new investments.
Daylight Prediction In Individual Floors Using Well Index
Authors: Mohsenin Mahsan , Hu Jianxin
Published: September 2018

This research is focused on assessing daylight performance in different floors based on the building proportion. Previous studies showed that atrium with the same Well Index (proportion) will receive the same daylight. This study aims to examine the relation between daylight in different floors of a building, using Well Index.

Using DIVA for Rhino and DesignBuilder as the optimized daylight and energy simulation tools, this paper employs Daylight Autonomy (DA) and thermal performance as measured metrics.

The research findings have demonstrated that Well Index can be a valid indicator to characterize proportion for assessing daylight at individual floors in buildings. This methodology improves the existing research method by proving that spaces with the same Well Index will have very close dynamic daylight metrics under the same condition, assumptions and material properties.

Authors: Popiolek Zbigniew , Kateusz Przemysław
Published: September 2018

The Polish National Centre for Research and Development has been coordinating the implementation of a strategic research project “Integrated System for Reducing Energy Consumption in the Maintenance of Buildings”. The main goal of the project is to support Poland’s efforts to reduce energy consumption in buildings, which is a strategic goal of the European Union. Within the scope of the aforementioned project, Task 4, “Development of thermal diagnostics of buildings”, was realized. Silesian University of Technology in Gliwice was a leader of the scientific-industrial consortium implementing the task. The main objectives of Task 4 and achieved relevant results are presented in the paper. A new method for the rapid on-site thermal diagnosis of a building envelope and systems of heating, ventilation, air conditioning and domestic hot water preparation and the diagnosis of indoor environment quality, as well as a method for drawing up energy performance certificates based on the measurements were developed.

Authors: Bartosz Dorota , SpecjaŁ Aleksandra
Published: September 2018

The paper analyzes the possibility of using the energy signature method based on the linear regression to determine the seasonal energy demand for cooling and ventilation in the office building. The “extended” energy signature method (H-m method) was described and applied. In accordance with Standard (EN 15603) the estimation of energy consumption for cooling can be performed for a period shorter than the entire season, but data range must be appropriate to obtain the correct accuracy of the results. The presented analysis concerns the uncertainty of estimation the seasonal demand for cooling and ventilation of the building based on monthly and 14-day data. The objective was to choose the shortest possible time period in order to obtain proper accuracy. It has been shown that the H-m method cannot be used to estimate cooling demand based on short-term (monthly or 14-days) data due to unacceptable uncertainty of results.

The main goal of the Task 4 “Development of thermal diagnostics of buildings” of Strategic Research Project “Integrated System for Reducing Energy Consumption in the Maintenance of Buildings” was to develop new tools for thermal diagnostics of different types of buildings, including development of the rapid method of a cooling sources diagnostics. The paper presents a method for assessing the cooling sources based on on-site measurements. The cooling capacity of the cooling sources and the electric power consumed by the cooling sources were measured in two air-conditioned office buildings. The measurement results were used to calculate the cooling energy generated during the measurement period and the operational Energy Efficiency Ratio EERo
of the chillers. Electric energy consumed in the measuring period by the auxiliary equipment of the cooling system, i.e.: coolant pumps and fan coil fans, was estimated. The possibility of significant reduction of the energy consumption for air conditioning in both buildings was indicated.
PARAMETRIC SHAPING OF CONSISTENT ARCHITECTURAL FORMS FOR BUILDINGS ROOFED WITH CORRUGATED SHELL SHEETING
Authors: ABRAMCZYK Jacek
Published: September 2018

The paper presents a method for a parametric shaping of innovative building free forms covered with corrugated steel shell roofs and flat glass elevation walls. Each shell roof is made of plane steel sheets folded in one direction and transformed elastically into spatial shape. The obtained shapes can be really diversified sectors of various ruled surfaces. Therefore there is a great need for creating such a method that leads to a fine integration of the shapes of a free form shell roof and plane oblique elevation walls for each building free form. Thus, it was elaborated the innovative parametric method, whose algorithm allows for seeking attractive and consistent architectural free forms by means of computer programs. A relatively small set of initial relevant parameters enables the designer intuitively to affect the attractiveness of the designed free forms. Some special attention is paid to selected fine proportions of these geometrical parameters leading to the really attractive architectural free forms.
SURFACE BLAST-CLEANING WASTE AS A REPLACEMENT OF FINE AGGREGATE IN CONCRETE
Authors: KUBISSA Wojciech , JASKULSKI Roman , SIMON Tamás
Published: September 2018

In the article the possibility of using a surface blast-cleaning waste as a replacement of fine aggregate in concrete manufacturing was presented. Concretes with w/c ratio 0.6 and 300 kg/m3 dosage of cements: CEM I 32.5R and CEM II/B-V 32.5N were tested. The quite high value of the w/c ratio resulted in good compactibility of the mixtures without use of plasticizer. The replacement rate of the fine aggregate (0–2 mm) with copper slag (CS) was 33%, 66% and 100% respectively. Concretes of the same composition served for reference except for with river sand as fine aggregate instead of slag. The performed tests focused on: compressive and tensile strength (both after 28 days), sorptivity, free water absorption capacity and abrasion resistance. The obtained results showed that the strength and some other tested properties of concretes with copper slag as sand replacement were similar or even better than that of the control mixtures.
APPLICATION OF POTENTIOSTATIC MEASUREMENTS ACCORDING TO PN-EN 480-14 IN ASSESSMENT OF THE EFFICIENCY OF REINFORCEMENT PROTECTION AGAINST CORROSION BY CONCRETE WITH ADDITION OF FLY ASHES
Authors: DOMAGAŁA Katarzyna , ŚLIWKA Andrzej
Published: September 2018

Replacing part of the cement in the concrete with fly ash – products of solid fuel burning, requires testing, including the degree of the reinforcement protection against corrosion provided by concrete. The paper presents a comparison of the results of the tests of the effectiveness of corrosion protection of reinforced concrete with the addition of calcareous fly ash. Tests were conducted by two electrochemical methods. Results obtained by potentiostatic measurement on reinforcement inserts deposited in cylindrical specimens in accordance with EN 480-14 standard were compared with studies investigating the progress of reinforcement corrosion caused by chlorides in loaded and cracked test elements made of these concretes. Tests of the cracked elements reflect the behaviour of reinforced concrete construction during operation in adverse environmental conditions, classified as standard XD and XS exposure classes. Comparison of the tests indicates the potential for potentiostatic measurement to be used to current assessment of protective properties of concrete with mineral additives.

Published: September 2018

This paper presents discussion of the problem of rural sanitation economic sustainability, affecting the overall investment agreement with the principles of sustainable development. In our opinion, economic aspects of sustainability, understood as affordability and profitability of the investment are crucial because they affect the social acceptance and willingness to pay by the members of rural communities. Additionally, it was proposed to use the well-known decision-making indicators of cost efficiency to assess the economic sustainability of rural sanitation. Four different variants of rural sanitation, centralized and decentralized, utilizing up-to-date state of art and technologies, were developed and tested with use of NPV, BCR and DGC indicators. The performed multivariate analysis using Weighted Sum Model showed the low profitability of centralized systems of rural sanitation, thus their sustainability may be questioned from economic and social point of view.

APPLICATION OF THE ANALYTIC HIERARCHY PROCESS (AHP) FOR ACOUSTIC ADAPTATION OF CLASSROOMS
Authors: NOWOŚWIAT Artur , SZURMAN Florentyna
Published: September 2018

In the paper we put forward a proposition of acoustic adaptation of classrooms based on the analytical hierarchy process (AHP). The main objective of such an adaptation is to increase speech intelligibility aiming to enhance the teaching quality level. The model is based on four main criteria which have impact both on the teaching process and on the adaptation costs. The said criteria comprise reverberation time, speech transmission index STI, financial cost of the adaptation and non-economic costs. The priorities and significance of the main criteria are identified by way of measureable calculations involving reverberation time, STI, costs and expertise, intangible, non-economic cost estimations. The AHP analysis should be viewed as a framework facilitating decision making processes applied in scientific or engineering analyses. The paper demonstrates the acoustic adaptation method of classrooms in terms of acoustic parameters and implementation costs of such an adaptation. The AHP analysis can help architects and classroom users adopt a more rational approach to further optimization and work out a definite building process which could provide a platform to compare different alternatives on a common and comprehensive basis.

Authors: NOWAK Robert , IMPEROWICZ-PAWLACZYK Anna
Published: September 2018

In this work, attention has been paid to the problem of quality of groundwater, which is the main source of supply of drinking water for rural inhabitants. In particular, the important factors for the groundwater quality in rural areas have been presented. This paper also shows the impact of the quality and quantity of available water resources on the exploitation of chosen small water intakes. Results of research on the quality parameters of groundwater, obtained in 2012÷2016 for selected rural intakes in north-western Poland, were presented. There was an increase in the content of iron and manganese compounds, ammonium ions, as well as the presence of bacteriological contaminants in test water samples. For these reasons, problems with providing the receivers with water of appropriate quality parameters have been reported in described rural intakes. The paper is an attempt to show the relationship between the type and magnitude of changes in the groundwater quality and the efficiency of the water treatment. In addition, pro-quality activities undertaken by local water companies were emphasized.

Authors: KACZMARCZYK Jan , LIPCZYŃSKA Aleksandra , KATEUSZ Przemysław
Published: September 2018

The indoor environment determines the occupants’ comfort and significantly affects the energy consumed for heating and ventilating the building premises. Therefore, the proper complex thermal diagnostics of existing buildings requires a fair assessment of indoor environment conditions. The method for measuring and assessing the quality of the thermal environment and the quality of the indoor air is demonstrated through the example of two single-family houses and one apartment in a multi-family house. In this paper, attention was paid to the issues that should be taken into account when conducting indoor environment diagnostics in residential buildings.

Soybean meal is the main vegetable protein source in animal feed. Soybean meal contains several anti-nutritional factors, which directly affect digestion and absorption of soy protein, thereby reducing growth performance and value in animals. Fermented soybean meal is rich in probiotics and functional metabolites, which facilitates soybean protein digestion, absorption and utilization in piglets. However, the mixed solid-state fermentation (SSF) conditions of soybean meal remain to be optimized. In this study, we investigated the optimal parameters for SSF of soybean meal by Lactobacillus species and Clostridium butyricum. The results showed that two days of fermentation was sufficient to increase the viable count of bacteria, lactic acid levels and degradation of soybean protein in fermented soybean meal at the initial moisture content of 50%. The pH value, lowering sugar content and oligosaccharides in fermented soybean meal, was significantly reduced at the initial moisture content of 50% after two days of fermentation. Furthermore, the exogenous proteases used in combination with probiotics supplementation were further able to enhance the viable count of bacteria, degradation of soybean protein and lactic acid level in the fermented soybean meal. In addition, the pH value and sugar content in fermented soybean meal were considerably reduced in the presence of both proteases and probiotics. Furthermore, the fermented soybean meal also showed antibacterial activity against Staphylococcus aureus and Escherichia coli. These results together suggest that supplementation of both proteases and probiotics in SSF improves the nutritional value of fermented soybean meal and this is suitable as a protein source in animal feed.

The growing number of children with overweight and obesity constitutes a major health problem of the modern world and it has been suggested that intestinal microbiota may influence energy intake from food. The objectives of this study were to determine quantity and proportions of dominant genera of Bacteroides, Prevotella (phylum Bacteroidetes); Clostridium, Lactobacillus (phylum Firmicutes) and Bifidobacterium (phylum Actinobacteria) in the intestines and to determine the content of short-chain fatty acids (SCFAs) and branched-chain fatty acids (BCFAs) in the stool of 20 obese children and 20 children with normal body weight. Strains classified as Firmicutes (Clostridium and Lactobacillus) predominated in stool microbiota of obese children, while those of Bacteroidetes (Prevotella and Bacteroides) were in minority (p < 0.001). Concentration of SCFAs in the stool of obese children was lower in comparison to the stool of normal weight children (p = 0.04). However, these differences were significant only in obese children, not in overweight children in comparison with the lean ones. Therefore, in our study obesity was associated with intestinal dysbiosis and a predominance of phylum Firmicutes. Secondly, stool of obese children contained lower amounts of SCFAs.
Are Probiotic Really Safe for Humans?
Authors: ZAWISTOWSKA-ROJEK ANNA , TYSKI STEFAN
Published: September 2018

Probiotic bacteria have been used as a health-promoting factor for a very long time. Nowadays, products containing probiotic bacteria are becoming more and more popular on the market. The term probiotics refers to the products belonging to the following groups: probiotic drugs (medicinal products – live biotherapeutic products for human use), medical devices, probiotic foods (e.g. foods, food ingredients, dietary supplements or food for special medical purposes), directly fed microorganisms (for animal use) and designer probiotics (genetically modified probiotics). Safety assessment of bacterial strains used as probiotics should be carefully studied. Even though probiotic bacteria have the generally recognized as safe (GRAS status), there are several reports about side effects triggered by the presence of these organisms. Microorganisms used as probiotics may cause systemic infections, stimulate the immune system, disturb metabolism and participate in horizontal gene transfer.

The growing resistance of microorganisms towards antibiotics has become a serious global problem. Therapeutics with novel chemical scaffolds and/or mechanisms of action are urgently needed to combat infections caused by multidrug resistant pathogens, including bacteria, fungi and viruses. Development of novel antimicrobial agents is still highly dependent on the discovery of new natural products. At present, most antimicrobial drugs used in medicine are of natural origin. Among the natural producers of bioactive substances, Actinobacteria continue to be an important source of novel secondary metabolites for drug application. In this review, the authors report on the bioactive antimicrobial secondary metabolites of Actinobacteria that were described between 2011 and April 2018. Special attention is paid to the chemical scaffolds, biological activities and origin of these novel antibacterial, antifungal and antiviral compounds. Arenimycin C, chromopeptide lactone RSP 01, kocurin, macrolactins A1 and B1, chaxamycin D as well as anthracimycin are regarded as the most effective compounds with antibacterial activity. In turn, the highest potency among selected antifungal compounds is exhibited by enduspeptide B, neomaclafungins A-I and kribelloside D, while ahmpatinin iBu, antimycin A1a, and pentapeptide 4862F are recognized as the strongest antiviral agents.
Analysis of the performance indicators of oil well sucker-rod pumps
Authors: Eyvazova Z. E. , Farajov T. E.
Published: September 2018

The paper notes that as the depths of operated wells grow, the application of cable and pulley mechanisms becomes preferable as compared to the existing pumpjacks. A generalized theoretical analysis of the kinematics of cable and pulley drives is set forth. The authors present the general theoretical analysis of the kinematics of the above mechanisms, as well as the results of computer calculations based of the developed equations for a number of cases. Further analysis of the results showed that the crank mechanisms of a rope pulley have “smooth” kinematics. The research resulted in a proposed invention of the design of mast-type oil well sucker-rod pump drive with lower steel intensity and power consumption that would allow increasing the performance of sucker-rod pumps.

The Purpose of this article consists in finding a utility model of a pump for the well rod in order to ensure the environmental safety of the equipment. That is achieved by lightening the metal structure of the pump with rotary stem and energy consumption is reduced. In the context of this problem, some calculations were performed in order to prove the system’s dependability. Based on the performed calculations it was established that the light structure can be used instead of the old heavy structure being its environmentally safe version. Experimental studies conducted by AzINMASH Research and Design Institute of Petroleum Engineering (Baku, Azerbaijan) indicate the feasibility of normal operation of sucker-rod pumps under the condition that n∙S = 54÷60 m/min. The authors examined the dependence between the peak output Q and the number of strokes n for various standard pumpjack sizes. The analysis of the parameters shown that the value of the product n∙S in the existing pumpjacks is below the recommendations based on experimental data, i.e. there is a tangible opportunity of increasing the productivity by extending the stroke of the rod hanger center, since well pump barrels may be as long as 6 to 7 meters. Estimates show that while studying the kinematics of long-stroke drives the changes in the length of the rope may be practically disregarded due to the displacement of the rope-to-pulley contact point. This simplifies the formulas that describe the kinematics of this type of long-stroke drives. Using the resulting formulas, comparative computer calculations for various cases were performed. It is shown that cable and pulley mechanisms have “softer” kinematics. The calculations confirmed the advisability of modification of the pump’s design that ensured reduced pollution of environment and energy savings. The future world will need renewable sources of energy, more power-efficient oil and gas production, minimal or zero pollution of the environment, thus the proposed solution appears to be of relevance. The authors propose a more productive design of sucker-rod pump that is easy to install and maintain at oil and gas production facilities. That can be achieved based on the calculations mentioned above.

Sobre lo político: Schmitt contra Schmitt
Authors: Arditi Benjamín
Published: September 2018

Un comentario habitual en los estudios acerca de la obra de Carl Schmitt es que su concepto de lo político oscila entre la nostalgia por el Estado fuerte de la era westfaliana y la convicción de que la escena política contemporánea ha cambiado irremediablemente al poblarse con nuevos actores, tanto estatales como no estatales. A pesar de esta ambivalencia hay vetas importantes que vale la pena desarrollar pensando con Schmitt y a la vez contra él, sea navegando a través de su teoría de lo político, sin avalar todas las consecuencias que extrae de ellas, o llevando su reflexión en una dirección que no contempló o en la cual no pudo o no quiso ir. En este trabajo discutiré algunas de las tensiones en su reflexión –la naturaleza del nexo entre guerra y política, al estatuto del enemigo y el argumento normativo acerca del orden como bueno en sí mismo– para luego examinar su distinción entre la política y lo político –tal vez su aporte más original y duradero al pensamiento político contemporáneo– y desarrollar el tema de la doble inscripción de lo político.
Inserción de problemas públicos del sector ambiental en la agenda institucional de organizaciones legislativas locales
Authors: Contreras Manrique Julio César , García Méndez Érika
Published: September 2018

Este trabajo aborda la agendación de problemas públicos en el espacio institucional de la organización legislativa local tomando el caso de un problema público del sector ambiental originado por la actividad de la compañía Minera San Xavier en la localidad de Cerro de San Pedro, San Luis Potosí, México. Encuadrado teóricamente en la concepción tripartita de las organizaciones de partido político y en el proceso de las políticas públicas, muestra la relevancia de los activistas partisanos cuando se desempeñan en cargos públicos para definir la participación activa de las organizaciones políticas en la promoción de problemas públicos así como la importancia de empatar los valores de las coaliciones promotoras con los principios partidistas de las fracciones y representaciones parlamentarias locales para lograr la introducción de dichos problemas en la agenda institucional.
Las fuerzas armadas y el crimen organizado en la democracia mexicana
Authors: Nava Hernández Mauricio Manuel
Published: September 2018

La actuación del crimen organizado ha sido un elemento fundamental dentro del proceso de deterioro de la calidad de la democracia en países latinoamericanos como México, Brasil o Colombia, a lo que se debe sumar el papel creciente de las fuerzas armadas para asegurar las libertades políticas y civiles de la población en estos países y garantizar la democracia, lo cual llega a ser un tanto irónico para muchos países de la región que sufrieron dictaduras militares antes de lograr su transición democrática. Así pues, el caso mexicano se puede destacar por su proceso de transición pacífica a la democracia debido a la relativa poca injerencia que habían tenido los militares en los asuntos políticos del país. En este sentido, resulta interesante la forma en la que fenómenos como el crimen organizado, particularmente el narcotráfico, comenzaron a derivar en un incremento de la influencia de los militares mexicanos en asuntos políticos como consecuencia de las nuevas prerrogativas que se les otorgaban para hacer prevalecer la paz interna, defender la democracia y combatir al narcotráfico.
Las ideas y el proceso político en las estrategias para hacer frente a la crisis del agua. Dos casos mexicanos
Authors: Caldera Ortega Alex Ricardo
Published: September 2018

Si se asume que la actual crisis del agua, es una crisis de gobernanza, es decir, que los principales retos se ubican en las instituciones para la toma de decisiones, la resolución de conflictos y la coordinación entre los actores involucrados, las perspectivas neoinstitucionalistas se presentan como un marco teórico-conceptual útil para abordar los procesos políticos alrededor del diseño de instituciones y generación de estrategias para hacer frente a los problemas de escasez y degradación de los recursos hídricos. Recientemente en ciencia política se habla de un neoinstitucionalismo de cuarto tipo, el llamado Nuevo Institucionalismo Discursivo, esencialmente interesado en identificar el conjunto de ideas detrás del proceso de hechura de políticas públicas y diseño institucional. El presente trabajo es una revisión de este planteamiento a la luz de los casos de los acuíferos del Valle de Aguascalientes y el Valle de León, ubicados en el centro de México, los cuales enfrentan una seria crisis del agua en lo local.

Eficacia ritual y efectos sensibles. Exploraciones de experiencias perceptivas wixaritari (huicholas)
Authors: Kindl Olivia
Published: September 2018

Este ensayo se enfoca en los aspectos sensibles que caracterizan diferentes acciones rituales llevadas a cabo por los wixaritari (huicholes). El uso y manejo de, por ejemplo, ciertos colores, formas, juegos de luces y sombras, sonidos y temperaturas son descritos en virtud del papel determinante que —se plantea— juegan en los contextos ceremoniales descritos. Además, se observa que en ocasiones algunas instancias sensoriales pueden cobrar vida o, dicho de otro modo, adquirir un cierto grado de agencia (agency, según Gell, 1998). En efecto, pueden manifestar la presencia de seres vivos, difuntos y/o antepasados-dioses. Se interrogarán los diversos puntos de vista que intervienen en estos contextos ceremoniales y desde los cuales se manejan aspectos sensoriales para lograr cierta eficacia. Así, desde un enfoque dinámico y fundamentado en la observación de las acciones concretas (sin obviar las exégesis al respecto), en el cual se consideran las acciones rituales como procesos creativos, se reflexionará sobre las imbricaciones entre dichas prácticas y efectos sensibles. El horizonte más amplio en el que este análisis se sitúa atañe a las articulaciones entre arte y ritual. Se retomarán fragmentos etnográficos observados en rituales muy diferentes practicados por los huicholes: actividades realizadas por los peyoteros durante sus peregrinaciones, en particular a la zona de Wirikuta (altiplano potosino); ceremonias de Hikuri Neixa (Danza del Peyote) y de Tatei Neixa (Danza de Nuestras Madres, también llamada Fiesta del Tambor); celebraciones de Semana Santa, y una “corrida del alma” (ritual funerario).

El texto es resultado de la experiencia etnográfica realizada en la Calzada de Guadalupe o Avenida Juárez, una de las vías más importantes de la Ciudad de San Luis Potosí. El avance de esta investigación nos remite a la transformación que ha tenido éste espacio urbano al cabo de los años, y sobre todo desde su origen procesional, como ruta hacia el Santuario de Guadalupe, hasta su modernización como corredor urbano y atractivo turístico en la época reciente. El uso social de la Calzada o Avenida que estudiamos, evidencia la diversidad de contactos y presencias humanas que, dentro de un espacio pueden verse influidos, lo mismo por la fe que por las actividades educativas y comerciales, incluso turísticas, y cómo la confluencia de todas le otorgan una significación relevante para la capital potosina.

La configuración de la maternidad a través de la inversión social en los niños. Ejemplos de Canadá y México
Authors: Luccisano Lucy , Wall Glenda
Published: September 2018

Como ha sido señalado por otros estudiosos en el ámbito del posneoliberalismo, la inversión social dirigida a grupos en riesgo se ha convertido en el enfoque central para los gastos sociales de los Estados-nación alrededor del mundo, y los niños, dado su potencial inherente, se han convertido cada vez más en el enfoque de las inversiones del Estado dirigidas a mejorar su futura integración en la economía de mercado. Este artículo detalla los resultados de dos casos de estudio de la regulación de la maternidad en dos contextos muy diferentes en los que las técnicas neoliberales dirigen la inversión hacia los niños. En Canadá, recientes campañas han instado a las madres a que inviertan grandes cantidades en sus hijos durante sus primeros años con el fin de mejorar su desarrollo cerebral y su eventual éxito en el mercado. En México, el programa antipobreza patrocinado por el Estado pretende aumentar el desarrollo del capital humano de los niños a través del sistema educativo como una manera de asegurar la futura inserción de los mexicanos de zonas rurales en la economía de mercado. Se comparan los resultados de entrevistas en profundidad realizadas con madres en el sur de Ontario y en zonas rurales de México. Si bien las experiencias de estas madres están marcadas por muchas diferencias culturales y de clase social, existen similitudes sorprendentes en términos de los efectos de un marco de inversión social en la regulación de la maternidad.
La influencia de los regímenes internacionales sobre los Derechos de la Infancia en el régimen de adopciones en México
Authors: Alonso Soriano Ana Lucía
Published: September 2018

El presente artículo pretende analizar la influencia de los regímenes internacionales sobre los derechos de la infancia en el sistema mexicano de adopciones internacionales, es decir, las adopciones de niños mexicanos hechas por extranjeros. La importancia de realizar esta investigación desde el enfoque de las Relaciones Internacionales (RI) es que dicha disciplina ofrece las herramientas necesarias para explicar la influencia de los regímenes internacionales en la agenda de los Estados sobre determinados grupos al interior de la Sociedad. La pregunta que intento responder en este artículo es: ¿han influido los regímenes internacionales relativos a los derechos de la infancia en la política de adopción transnacional en México? La internalización de las normas internacionales en esta materia garantizaría que las reformas legales al sistema de adopciones mexicano tuvieran como fin privilegiar los derechos de los niños en esta condición. Esta influencia de las normas se debería de apreciar en reformas y cambios en la Constitución, leyes federales y locales para que los procesos de adopción internacional se realicen según lo establecido en los tratados internacionales a los que México adoptó.

Imperio, imperialismo y violencia: una visión desde la periferia
Authors: Curcó Cobos Felipe
Published: September 2018

Este ensayo reflexiona sobre la crisis de las instituciones ciudadanas del Estado y de la sociedad civil como consecuencia del proceso de globalización actual. Efecto de este proceso es que los Gobiernos locales se ven cada vez más obligados a orientar su política conforme a los criterios de flujos económicos globales. Con ello, los Estados ven desbordada su capacidad de gestión, con lo que tienden a sacrificar intereses de sectores hasta entonces protegidos por ellos. Este texto se dirige a reflexionar sobre los fenómenos de exclusión, violencia y subalternidad que dicha exclusión genera. Su interés es hacer una exploración crítica de tres categorías analíticas centrales: imperio, imperialismo y multitud, a partir de la importante obra publicada en el año 2000 por Hardt y Negri. Al final, se mostrará su importancia para desvelar diversos fenómenos derivados de esta condición mundial y la violencia que genera, así como la necesidad de analizar el pensamiento de Hardt y Negri a partir de ciertas coordenadas de reflexión latinas.
El humanismo radical de Juan Carlos Onetti
Authors: Martínez González Víctor Hugo
Published: September 2018

Juan Carlos Onetti es un autor universal, pero veinte años después de su muerte es aún visto como un escritor para lectores atormentados. Este ensayo demuestra cómo ese y otros prejuicios son un error. Para contestar los lugares comunes y falsos sobre Onetti, aquí se exploran diferentes hipótesis sobre su grandeza y se subraya la raíz humana de sus ficciones.
Recuperación de cascos hacendarios en México: El ecomuseo como alternativa
Authors: Flores García Laura Gemma
Published: September 2018

A partir de las características del patrimonio construido forjado en la diversidad tipológica de los cascos hacendarios en México, se visualiza la potencialidad de su uso. Para ello se procede a la revisión crítica de los usos actuales que se les han conferido a dichos espacios a través del planteamiento de estrategias de recuperación y aprovechamiento, desde el marco de la economía aplicada a la cultura. La sugerencia específica plantea, de acuerdo con cuatro dimensiones: cohesión territorial, dimensión económica, cohesión social y restauración, la creación del ecomuseo como experiencia alternativa probada tanto en Europa como en América Latina.
Identidades renovadas en ciudad tomada de Maurico Montiel Figueiras
Authors: Castillo Garcia Maria Esther
Published: September 2018

Montiel Figueiras, al asumir el balance estético cortazariano, enfatiza la necesidad del intertexto en tanto conocimiento y fundamento de la antología Ciudad tomada. Su obra emprende una búsqueda similar a través de personajes que bien revelan la percepción de un espacio contradictorio pleno de reacciones dolorosas, angustias presentidas que deben traspasar la memoria o la imagen imprecisa de una “presencia animal”, como también de expresiones de carácter adjetivo que subrayan el dejo irónico y corrosivo de la ficción.
