Os modelos de previsão aplicados foram os modelos ARIMA com intervenção e ARIMA X-12, os quais apresentaram uma previsão de demanda adequada para o planejamento dos recursos a serem aplicados na área de turismo na localidade estudada cuja previsão de crescimento para os próximos anos pode ser usada para tomadas de decisão estratégica relacionadas ao crescimento turístico.
The Social Evolution of World Politics
Authors: Albert Mathias , Brunkhorst Hauke , Neumann Iver B. , Stetter Stephan
Published: September 2023

How can we understand long-term change in world politics better? Based on readings of thinkers as diverse as Habermas, Foucault and Luhmann, the authors of this book propose a framework for understanding such change in terms of social evolution. They show that processes of social learning and unlearning are key to understanding the long-term historical evolution of complex societies, and propose to approach these with the core concepts of autonomization, hierarchical complexity, and co-evolution. Three case studies illustrate this social evolutionary perspective to the study of world politics, examining the evolution of forms of organizing political authority, of conflicts, of diplomacy, of law as boundary condition.
Religion im urbanen Raum
Authors: Kanitz Juliane , Moos Thorsten , Zarnow Christopher
Published: September 2023

Religion existiert nicht im luftleeren Raum. Sie ist gebunden an Orte und Gebäude, lokale Gepflogenheiten und regionale Mentalitäten. Auch die vermeintlich säkulare Stadt erweist sich bei näherer Betrachtung als religiös geprägter Raum. Kirchtürme und Minarette sind weithin sichtbare Manifestationen von Transzendenz. Umgekehrt schreiben sich die Materialität des Stadtraums, seine soziale Schichtung und kulturelle Diversität in das religiöse Leben ein. In einer qualitativ-empirischen Untersuchung neuer Stadtquartiere beschreiben die Autor*innen Prozesse und Strukturen der Verräumlichung von Religion im urbanen Raum und interpretieren diese vor dem Hintergrund aktueller sozialwissenschaftlicher Debatten.

Nanoarchitectonics and performance evaluation of a Fe3O4-stabilized Pickering emulsion-type differential pressure plugging agent
Authors: Zhao Chun , He Mengqi , Duan Jibin , Wang Jiaqi , Fan Zhenzhong , Tong Qilei
Published: September 2023

With the rapid growth of natural gas consumption capacity, the important role of gas storage in seasonal peak shaving and emergency response is gradually emerging. Long-term forced production and injection of gas storage will lead to problems such as wellhead equipment leakage and string seal failure. Replacing the string is not only costly but also takes a long time. Aiming at thread leakage caused by multiple rounds of forced production and injection in gas storage, a Pickering emulsion differential pressure plugging agent with a self-sealing function under a certain pressure difference was developed. We selected carboxyl nitrile latex with a self-polymerization function and modified the nano-stabilizer Fe3O4@SiO2. The Pickering differential pressure plugging agent with excellent plugging performance was prepared by the combination of modified particles and non-ionic emulsifier OP-10. The plugging test was carried out for the simulated oil pipe thread. When the leakage rate was 50 mL/min, no leakage occurred under a pressure of 20 MPa after plugging. The differential pressure plugging agent is expected to achieve plugging without moving the pipe string and rebuild the integrity of the wellbore.

Published: September 2023

In order to realize the automatic detection system of electric sensor, a method based on sensor and nonlinear machine vision is proposed. Aiming at complex scenes and dynamic changes in target recognition and detection in large-scale industrial field, a target recognition and detection system based on the fusion of vision sensor and nonlinear machine vision is proposed. The system introduces nonlinear features and uses deep neural network to realize multi-scale analysis and recognition of image data on the basis of traditional machine vision. The system uses C++ language development and has a good user interface. The photoelectric sensor weld image is collected by machine vision technology, the target area of the image is detected by Gaussian model, the feature points of the target area are extracted by combining Hessian matrix, the extracted feature points are input into the quantum gate neural network model, and the recognition results are obtained. The simulation results show that the author’s method has the highest value among the three test indicators, with the highest accuracy rate of 97%, the highest recall rate of 98%, and the highestF1 value of 94. The time consumed by the author’s method for automatic identification of photoelectric sensor welding is within 6 s, the time spent on the film wall recognition method for automatic identification of photoelectric sensor welding is within 20 s, and the time spent by the feature extraction and identification method for automatic identification of photoelectric sensor weld is within 22 s. It has been proven that the method based on the fusion of sensors and nonlinear machine vision can achieve an automatic recognition and detection system for electrical sensor welds. The object detection and recognition method proposed in this article can be applied to dynamic changes and complex scenes in various complex backgrounds and has a good application prospect. The system proposed in this article has some limitations, such as the algorithm in the calculation accuracy, real-time, and other aspects that have room for improvement.
High-Performance Programs for First Responders: Considerations and Potential Benefits of Implementation
Authors: Lockie Robert G. , Dawes J. Jay
Published: September 2023

In recent years, tactical personnel, especially within the military, have integrated sports science–related practices into their training. This effort has been less pronounced with first responders (police, firefighters, emergency services), despite the structured academy training typically completed by recruits, challenging job tasks and long-term health, fitness, and wellness concerns. One example of how sports science practices could be applied for first responders is through high-performance programs. High-performance programs are commonplace within elite sport and can help set roadmaps for success. Numerous factors contribute to an effective program, much of which relates to the resources provided to personnel. This can include a multidisciplinary team (e.g., strength and conditioning coaches, athletic trainers/medical staff, psychologists, nutritionists, researchers) and appropriate resources (e.g., gyms, facilities, testing and training equipment). This review will discuss whether high-performance programs, or at least components of these programs, could be adopted in first-responder populations. The authors will discuss literature to demonstrate how and why high-performance programs could be implemented for first responders and whether these programs are aspirational, attainable, or objectionable. Finally, the authors will provide actionable high-performance program-related information for the strength and conditioning coach and tactical scientist working with first responders.

Somatostatin receptor expression and clinical outcome of multilineage pituitary tumours expressing PIT1 and SF1
Authors: Fookeerah Prishila , Varikatt Winny , Shingde Meena , Dexter Mark A J , McLean Mark
Published: September 2023

The application of transcription factor immunohistochemistry to pituitary neuroendocrine tumour (PitNET) assessment has allowed identification of tumours that do not conform to a single lineage. Multilineage pituitary transcription factor 1 (PIT1) and steroidogenic factor 1 (SF1) PitNETs are a rare and relatively newly described tumour subtype. These tumours express both transcription factors and may also express combinations of hormones corresponding to both lineages. Histological and clinical characteristics can vary, and overall clinical behaviour and prognosis is not known. We describe the clinical outcomes and somatostatin receptor status (SSTR) of a series of nine cases identified from our cohort of pituitary tumours at Westmead Hospital. Eight PitNETs (88.9%) expressed growth hormone and caused acromegaly at presentation. Of the seven macrotumours that caused acromegaly, one had cavernous sinus invasion. The Ki-67 labeling index score ranged from 0.6% to 3.6%. About 88% of tumours that secreted excess growth hormone exhibited strong immunostaining for SSTR 2 and all tumours displayed weak immunoreactivity for SSTR5. In 62.5% of patients with acromegaly, cure was achieved after surgical resection. Somatostatin receptor ligands resulted in clinical remission in cases where medical treatment was initiated. There was no new tumour recurrence or regrowth over an overall mean follow-up period of 62.5 months.

Published: September 2023

The aim of this study is to investigate the wear resistance of diamond-like carbon (DLC) films and wear debris of polyethylene using pin-on-disc testing on two groups of CoCrMo discs with DLC coatings. DLC coatings deposited with use high productive vacuum-arc filtered plasma source in two regimes: with and without Ti interlayer on CoCrMo discs. The Orthopaedic Innovation Centre performed 2.5 million cycles (Mc) of POD testing on two groups of CoCrMo discs with DLC based on ASTM G99-17. The discs used were made of wrought low carbon alloy CoCrMo according to ASTM F1537. Wear performance of the PE pins against the DLC coated discs was determined and reported below. Lubricant samples were collected for each group after 0.5 and 2.5 Mc of testing, and used to characterize wear particles. All PE pins were assessed for damage features following 2.5 Mc of wear testing. The damage features identified included burnishing, scratching and grooving. The new process of DLC coating deposition from filtered vacuum arc plasma flows allows obtaining the stable DLC coating on the CoCrMo substrate. Thus, considering the low friction coefficient and the stable behavior of DLC such coating would be highly perspective for CoCrMo artificial joint implants.

Suppression of Simultaneous Switching Noise Using Embedded Capacitor Method in High-Speed Systems
Authors: Saini Lakshya , Agarwal Ravinder
Published: September 2023

Gbps signals are commonly used in modern high-speed IO designs. These systems require a high level of signal accuracy. However, these signals can cause current fluctuations at high frequencies due to parasitic inductance on the package and board, leading to significant changes in supply voltage. DDRX interfaces that transmit data up to 4.8 Gbps induce simultaneous switching noise (SSN) in the voltage regulator module (VRM). One of the adverse effects of SSN is timing jitter, also known as power supply-induced jitter. The amount of SSN is directly proportional to the number of signals on a parallel bus. Discrete capacitors may not be effective in reducing SSN impact when data is transmitted at high speeds. The current approach used to predict and evaluate errors in SSNs relies on the designer's expertise, which requires accurate estimates of packaging parasitic. In this paper, a practical approach to lessen SSN is presented through the use of embedded capacitors placed between planes and optimizing discrete capacitors by connecting them in a way that measures the impact of supply noise on the I/O transistor circuit performance at the DDRX interface. Two boards were designed, evaluated, and subsequently compared their results.

Published: September 2023

This developmental study aimed to evaluate the disaster risk reduction and management (DRRM) capabilities, preparedness, and emergency response competence of Filipino school principals in Guimaras Island, while also developing a relevant contingency management planning toolkit tailored to the needs of the region. The study involved 92 deliberately selected participants, including public elementary and secondary school principals, as well as private school administrators. Data was collected using a researcher-made questionnaire consisting of three sections: DRRM Assessment Capability, Preparedness, and Emergency Response Competence. Descriptive statistics, including frequency counts, percentage analysis, mean, standard deviation, and rank, were used for data analysis. The results indicated that both public and private school principals in Guimaras demonstrated a high capability for risk assessment, substantial preparedness, and a significant level of competence in emergency response. Notably, their assessment capability was strongest in areas such as monitoring and evaluating DRRM programs and understanding Site Development Plans, while their least predominant skills were related to maintaining and strengthening lifeline systems and estimating equipment lifespans. In terms of DRRM preparedness, strengths included utilizing DepEd Orders for class suspensions during inclement weather and providing emergency contact directories. Weaknesses were identified in areas like capacitating student-led watch teams and preparing localized school policies for disaster preparedness. Regarding emergency response, school principals were found to be highly competent in managing personnel and coordinating with the Local DRRM Team. They were also proficient in providing necessities to teachers and students and reporting damages using the RADaR App. To address the identified gaps, a contextualized toolkit was proposed, tailored to the specific needs of Guimaras schools. This toolkit received excellent ratings from experts in terms of its attributes, objectives, content, usefulness, and self-help features.

Exo-erythrocytic stages of Haemoproteus (Apicomplexa, Haemosporida) parasites in wild birds: insights into developmental patterns
Authors:   , Duc Melanie Yvonne Ludivine
Published: September 2023

Avian haemosporidian parasites of the genus Haemoproteus (Apicomplexa, Haemosporida) are widespread and can cause mortality in non-adaptive hosts. Over 170 species of these parasites were described but little is known about their complete life cycles, especially exo-erythrocytic stages, which develop in the organs of their bird host. The objective was to expand the knowledge about exo-erythrocytic stages of Haemoproteus parasites in naturally infected birds and to unravel some patterns of their development. The results showed that the parasites were species-specific in regard of their exo-erythrocytic development, and this character is valuable for future taxonomic research. Haemoproteus majoris, H. pastoris and H. hirundinis developed megalomeronts (huge-size tissue stages) while H. dumbbellus and H. attenuatus developed only meronts (relatively small tissue stages). All found tissue stages were of different morphologies between the different parasites. The intensity of parasitemia was found to be an unreliable indicator of avian host with exo-erythrocytic stages. Chromogenic in situ hybridization technique was successfully used for the search of tissue stages and the confirmation of their generic identity. The obtained new data contribute to new knowledge about exo-erythrocytic development of Haemoproteus parasites, including the predictability of molecular phylogenies in investigation of tissue stages of avian haemoproteids.

Mosquitoes represent the most important agent disseminating infectious diseases like yellow fever, dengue, chikungunya, and malaria, among others. An essential strategy for its control is killing them at immature stages using industrial insecticides. However, those chemicals often generate resistance and affect the environment and human health. Agricultural and plant by-products constitute a new sustainable option to obtain harmless and eco-friendly bioinsecticides to prevent mosquitoes from spreading. This study aimed to investigate the phytochemical profile of Persea americana Mill (Lauraceae) seed extracts and their insecticide activity against Aedes aegypti at larval and pupal stages. The ethanol extracts from avocado seeds were obtained by Maceration/stirring (MaE) and Soxhlet extraction (SE) methods. The main chemical profile was determined by quantitative and UPLC assays. Insecticide activity was assessed by the exposition of mosquitoes at larval and pupal stages to seed extracts. Human cell lines were used to evaluate the cytotoxicity. Soxhlet methodology was more efficient in the extraction of P. americana seeds metabolites (42.13±1.76 mg/mL) compared with MaE (20.46±1.66 mg/mL) (p< 0.05). Additionally, SE showed a higher amount of polyphenols (5.12±0.18 mg/mL). The UPLC spectra analysis revealed the presence of polyphenols, mainly catechin, and neolignan constituents. Both extracts showed larvicidal and pupicidal effects, but SE was more active at lower concentrations. Moreover, no significant toxic effects on human monocytes and fibroblast cell lines were found after treatment. In sum, avocado seed by-products can be considered an eco-friendly insecticide and its use may help to substantially decrease the vector-transmitted diseases in developing countries.

Authors: Ruiz Molina Victoria Estefanía , Muñoz Perea Carlos Germán
Published: September 2023

La velocidad de infiltración básica (Vib) es un parámetro importante para planificar sistemas de irrigación; sin embargo, este parámetro se desconoce en la mayoría de suelos de ladera del Valle del Cauca, Colombia. Por tal razón, el objetivo de esta investigación fue determinar la Vib en tres zonas de ladera usando una nueva adaptación de goteros tipo Mariotte de bajo volumen de trabajo, a partir del área mojada y el caudal del gotero diseñado. La experimentación se desarrolló en tres zonas de ladera de Roldanillo, Dagua y Pradera en el Valle del Cauca, en cultivos de aguacate Hass, piña MD-2 y mora, respectivamente. Los suelos se clasificaron en: franco-limoso, arcilloso y arcillo-limoso, respectivamente. Se aplicaron láminas de agua de 2, 3, 3.5 y 4 litros usando el principio de gotero Mariotte y se distribuyeron a partir de un diseño completo al azar en cada finca. Se obtuvo el área mojada (Am) de cada una de las láminas aplicadas usando un software de procesamiento de imágenes. Se encontró que la longitud del diámetro de humedecimiento tiende a estabilizarse a partir de 2.26 litros a +/- 20 cm de profundidad, por lo que se estimaron velocidades de infiltración básica utilizando el modelo empírico de Kostiakov de 38.00 mm hr-1, 1.29 mm hr-1 y 1.40 mm hr-1 para cada zona de estudio. Se comprobó la relación entre el área de humedecimiento y el caudal aplicado por los goteros asociados a la velocidad de infiltración instantánea (vii).

Published: September 2023

Black pod rot (BPR), caused by several species of the genus Phytophthora, is one of the most limiting diseases for the production of cocoa as it appears in all of the producing regions of the world and generates significant losses. The aim of this study was to establish the response to this infection in six cacao clones (EET8, IMC67, TSH565, PA46, ICS95, and CCN51), through an inoculation test on detached fruits using five P. palmivora isolates from five producing regions. The incidence and severity of the disease in the detached pods were evaluated at six and ten days after inoculation (DAI). Clone CCN51 was classified as susceptible, and clones IMC67 and PA46 as moderately susceptible at six DAI. All the clones evaluated were categorized as susceptible at ten DAI. The HURV19 isolates of P. palmivora showed the highest aggressiveness compared to ANYA228, which was found to be the least aggressive.

Authors: Ramos Calderón Pablo Fernando , Rodriguez  Pérez Wilson , Castrillon Rivera Beatriz , Ramos Rodriguez Freddy Alejandro , Suárez Salazar Juan Carlos
Published: September 2023

Cacao (Theobroma cacao L.) is a crop of globally importance on whose production around 20 million people depend directly. The crop is threatened due to the incidence of diseases caused by phytopathogenic fungi such as Moniliophthora roreri, causing losses of more than 80 % of the annual production. For this reason, in this study, a natural product such as the essential oil (EO) obtained from Siparuna guianensis was evaluated as a control alternative. The chemical composition of the EO, as well as the antifungal effect in vitro and in vivo on M. roreri, the causal agent of moniliasis frosty pod rot, were determined in the cacao pods located in a commercial plantation in southern Huila, Colombia. 28 compounds were detected, predominating: D-Germacrene (26.5 %), (E)-nerolidol (21.5 %), β-caryophyllene (9.3 %), elemol (8.0 %), bicyclogermacrene (7.5 %), δ-elemene (3.5 %), β-elemene (3.0 %), and α-pineno (2.4 %). At a concentration of 1000 μg ml-1 of EO in vitro, an inhibitory effect of 98 % on the mycelial growth of M. roreri was obtained. In the in vivo test at concentrations of 1000 μg ml-1 and 750 μg ml-1, a direct relationship in the decrease of the incidence, external gravity, and internal gravity of M. roreri in cocoa pods was observed, using EO as fungicide. It was concluded that S. guianensis EO represents a great potential for the control of frosty pod rot.
Does this fruit look appetizing? Psychometric modeling of fruit consumption preferences
Authors: Arboleda Arango Ana Maria , Alonso Julio C. , Arce-Lopera Carlos A.
Published: September 2023

Consumers’ sensory evaluation of fruits to determine the expected quality is a frequent practice. However, consumers’ assessment of fruit quality is an ambiguous concept. This research aimed to determine the preferred fruit image when consumers decide that it is ready to eat, or it is too old. This within-subjects experimental design was conducted through an online survey using four fruits: avocado, banana, lulo, and guava. The questionnaire used a two-alternative forced-choice method: From a pair of fruit images, participants chose which one they preferred to eat, and which was too old. The results showed that participants do not always agree on the fruit image they find to be ready to eat, whereas the results for assessing an old fruit mimic the fruit maturity condition. Thus, food quality standards should use sensory evaluations that assess ideas that matter to the consumer. The value of this research is to provide a methodological approach to evaluate the consumers’ expectations, which will be helpful within agricultural processes and the distribution chain.

Septiembre de 2021: el triunfo islamista de los talibanes
Authors: Patiño Villa Carlos Alberto
Published: September 2023

El triunfo de los talibanes en Afganistán, tras la salida de tropas estadounidenses, tiene como consecuencia no solo importantes transformaciones sobre la sociedad afgana, sino también un cambio radical en la acción geoestratégica de las potencias con interés en Asia Central. Comprender los últimos acontecimientos de violencia en Afganistán implica remontarse al origen del fenómeno talibán, a las alianzas políticas que se crearon desde antes de la Guerra Fría, a la presencia de Al Qaeda y a la intervención de Estados Unidos después de los ataques del 11 de septiembre de 2001. Este capítulo se cierra, por el momento, con el fallido intento de las potencias occidentales de transformar un territorio caracterizado por luchas intertribales, corrupción sistémica y el retorno de los talibanes al poder de un Estado débil, pero con importantes apoyos internacionales que suponen cambios en la geopolítica mundial.

En este estudio se evaluó la sustentabilidad urbana de una ciudad intermedia en el contexto latinoamericano, para lo cual se tomó un sector piloto en la ciudad de Loja (Ecuador). Se utilizó la metodología de Evaluación de la Sustentabilidad Urbana a través de indicadores de  densificación urbana sustentable. Se recopiló información del sector y se aplicaron geoprocesos en QGis para visualizar y obtener indicadores de diversidad de uso y vivienda, accesibilidad peatonal, verde urbano e integración socioespacial. Los resultados revelaron valores bastante inferiores a los óptimos propuestos, cinco de los ocho indicadores alcanzan el valor óptimo en subsectores del área del estudio y 3 indicadores no lo alcanzan. El Indice de Densificación Urbana Sustentable es inferior a la mitad del valor referencial. En conclusión, el estudio muestra cuan bajo es el desarrollo urbano desde la visión de la sustentabilidad en un sector representativo de la ciudad, esto resalta la necesidad de realizar mediciones para establecer objetivos que orienten las políticas de planificación hacia la sustentabilidad y tiendan a disminuir las desigualdades urbanas.

We studied the rheophytic vascular flora of the middle Caquetá River basin in the Colombian Amazon, by sampling along the margins and islands of its two largest rapids, Angostura and Araracuara, along the rapids of the black-water Yarí river, its second largest tributary, and along a swift black-water creek flowing from a small Tepui into the latter. We identified and quantified rheophytes in 12 plots and collected other rheophytic species spotted outside the plots. We found 28 species of rheophytes, belonging to 20 families, mostly herbs and subshrubs. The rheophytic flora of the white-water Río Caquetá only shared three species, with that of the Yarí River; instead, the Yarí River shared no rheophytic species with its tributary creek, despite being just a few meters away. The family Podostemaceae dominates the extreme rheophytic belt, where the current hits the strongest. The most diverse families were Myrtaceae, and Xyridaceae (three species each); Acanthaceae (two species) is the most diverse family in the middle level, whereas Myrtaceae (three species) predominates in the upper rheophytic belt of small trees, and makes up a transition between the truly rheophytic and the riparian floras. The most abundant and frequent species was Pfaffia iresinoides (Amaranthaceae). Eight species are endemic to this area, and no species is shared with the other Neotropical areas where rheophytes have been surveyed.
Cuestiones de derecho, cuestiones de hecho: la paradoja del rol de las mujeres en la gestión y conservación de la biodiversidad en Argentina
Authors: Solans Mariana Laura
Published: September 2023

La reforma de la Constitución Argentina sancionada en 1994 significó el reconocimiento del derecho de todos los habitantes a un ambiente sano y equilibrado, apto para el desarrollo humano y para que las actividades productivas satisfagan las necesidades actuales, sin comprometer las de las generaciones futuras. En línea, el Estado argentino ha adherido y cumplido estos principios ambientales fundamentales, y desarrollado acuerdos e instrumentos jurídicos para potenciar la idea de igualdad de género en materia de protección ambiental. Ha reconocido el papel relevante de las mujeres en la conservación y el uso sostenible de la diversidad biológica. Mediante el análisis de la normativa vigente y de indicadores que dan cuenta de la presencia de mujeres en cargos de gestión gubernamental, este artículo muestra una paradójica brecha entre las normas jurídicas y los hechos, en relación con la participación plena y efectiva de las mujeres. Si bien ha habido avances significativos desde 1994 en la promoción e implementación de políticas dirigidas a la transversalización de la perspectiva de género y diversidad en algunas áreas de gobierno, como las Áreas Nacionales Protegidas (Parques Nacionales), aún prevalece la desigualdad en el acceso de las mujeres a los derechos relacionados con el medio ambiente.
El rol de las epistemologías feministas y trans* en la deconstrucción de la ciencia androcéntrica y [cis]sexista
Authors: Zimmermann Leila Selena
Published: September 2023

El género como categoría analítica ha sido objeto de diversas transformaciones y controversias al interior de las epistemologías feministas y trans*, las cuales se proponen desapegarse del paradigma androcéntrico con el objetivo de aportar a la deconstrucción de las ciencias desde distintas miradas respecto a las nociones de sexo y género. En primer lugar, el presente artículo tiene como objetivo describir las principales características de la ciencia androcéntrica en relación a la construcción y naturalización del sexo binario; y en una segunda instancia, analizar cuál es el rol que ocupan los estudios de género y las epistemologías feministas y trans* en el proceso de transformación de los sesgos androcéntricos y [cis]sexistas al interior de las ciencias. La metodología es de tipo cualitativa mediante análisis de fuentes bibliográficas. El trabajo concluye que el devenir de las epistemologías ubicadas en los márgenes de la ciencia androcéntrica continúa generando nuevos aportes y debates académico-activistas en las disputas del campo del saber, bajo la finalidad de erradicar los presupuestos de la ciencia como un espacio neutral, objetivo y ahistórico.
Apuntes en torno a los límites del género y potencias del patriarcado como categorías de análisis en la disputa por la reproducción de la vida desde México
Authors: Cornejo Hernández Amaranta
Published: September 2023

El presente artículo presenta apuntes en torno a algunas reflexiones críticas producidas por académicas-activistas que invitan a revisar la categoría patriarcado como un germen con el que (re)construir sentido en la intensa vida política, sacudiendo al género, en tanto categoría analítica, a la luz de los procesos histórico-feministas en la región, en el contexto de lo que en 2018 las zapatistas enunciaron como “una lucha multicoral por mantenernos vivas”. Así se revisita al género a la luz de propuestas teóricas de los feminismos materialistas, de la diferencia, intuitivos, y de la economía feminista emancipatoria, para dialogar a su vez con los renovados repertorios de acción feministas como son los paros y la producción de justicia feminista, los cuales disputan la reproducción social de la vida en un contexto de violencias exacerbadas en contra de las mujeres y seres feminizados.
Hydrodynamic and experimental characterization of pumps as turbines

Published: September 2023

To estimate the performance, efficacy, modes of operation, hydrodynamic instabilities, and methodologies for harnessing energy from the pump as turbine (PAT), it is necessary to characterize these hydraulic turbomachines in all their modes of operation using an experimental test rig that simulates actual operating conditions. In this process, the characteristic curve of four quadrants of a turbomachine is constructed, especially its five modes: pump mode, brake pump mode, turbine mode, brake turbine mode, and reverse pump mode. In addition, with dynamic sensors installed in the pump volute, it is possible to know the hydrodynamic phenomena within PAT, finding its average behavior and frequency response, which is a tool for diagnosing the machine’s condition.

Entre lo exógeno y lo exótico: las periferias, los supuestos económicos sobre Ciencia, Tecnología e Innovación y sus implicancias para el desarrollo tecno-productivo
Authors: Kataishi Rodrigo , Brixner Cristian
Published: September 2023

Este artículo discute los principales cimientos teóricos en la conceptualización acerca del rol de los sistemas de ciencia y tecnología (CyT) y su influencia sobre el plano productivo. Se desarrolla una sistematización de elementos conceptuales claves de la literatura y un análisis crítico de los componentes principales que emergen de las dos escuelas centrales de pensamiento en la materia: la neoclásica y la neoschumpeteriana. Las contribuciones y los aspectos diferenciales de este artículo se centran en la reflexión en torno a un diagnóstico que contrasta las realidades latinoamericanas con las ideas y supuestos clave de dichas teorías. Como conclusión, se señalan algunas inconsistencias entre los puntos de partida y los efectos esperados de las políticas de CyT derivados de supuestos económicos que no se adaptan fielmente a nuestra realidad. Finalmente, se recomienda el reconocimiento de las características y dinámicas propias de la periferia como paso inicial para pensar nuevas estrategias de intervención en el territorio.
Estructura productiva y terciarización en regiones periféricas de Argentina. Santiago del Estero en perspectiva comparada
Authors: Gurmendi María Noelia
Published: September 2023

En el presente artículo se propuso describir la estructura y terciarización productiva de la provincia de Santiago del Estero (históricamente como una de la más rezagada de Argentina), al concebir que esta provincia constituye un elemento medular para comprender la configuración social del país. Se estudió el período 2000-2007, ya que el análisis de estos años permite apreciar atributos en materia productiva, pero también identificar rezagos que fueron agudizando la heterogeneidad de la misma. Metodológicamente, el estudio aplicó análisis de series de tiempo y estimación lineal, para determinar la tasa de crecimiento por sector que permita acceder al análisis del comportamiento sectorial y participación productiva, advirtiendo las particularidades de su matriz en relación con la nación. El análisis se sustentó en los aportes teóricos neoestructuralista de la CEPAL, escuela que permite comprender la desigualdad social y económica de la región bajo contribuciones genuinas de la realidad latinoamericana. Por último, se evidenció que la sociedad santiagueña —subcapitalizada— se ha caracterizado por un proceso de transición degenerativa enmarcado en la terciarización forzada. Otra observación se vincula al hecho de la elevada participación productiva y laboral en actividades de baja productividad y dinamismo.
