CHRISTIAN-MUSLIM PEACEFUL COEXISTENCE: A SINE QUA NON FOR SUSTAINABLE DEVELOPMENT IN NIGERIA
Authors:   Baptist College of Theology, Benin City, Edo State, Nigeria, IFATOKUN Victor
Published: January 2024

The thrust of this work is on the necessity of peaceful coexistence between Christians and Muslims to enhance and strengthen sustainable development in Nigeria. Christianity and Islam are the two major and decisive religions in Nigeria. Deplorably, the two religions that should teach and promote love, tolerance, and unity as enshrined in both the Bible and al-Qur’an, have been subtlety used as an indicator of political and social identity in a way that rouse conflicts over resources, land, political and economic power. This has led to the upsurge in religious intolerance and bigotry, unbridled and aggressive action of the fundamentalists, wrong religious orientations, mindless selfishness among some religious leaders, and low level of religious literacy among some adherents, which is currently posing a crucial threat to sustainable development in Nigeria. Therefore, this study critically examines the interplay of peaceful coexistence between Christians and Muslims through dialogue for the transformation and sustainable development of Nigeria. The study employed a descriptive research method, purely based on written sources comprised of books, journals, and websites. The study, among other things, revealed that peaceful coexistence between Christians and Muslims is crucial for the economic, political, and social development of Nigeria. It was discovered that through dialogue, the intolerance and conflict situation in Nigeria can be transformed into a culture of peace characterized by respect, trust, liberty, tolerance, equality, and brotherliness that will foster sustainable development. The study, therefore, concluded with the recommendation that since religious isolation and bigotry are not conducive to sustainable progress and development, individual and religious institutions should embrace and proclaim dialogue reflecting brotherhood, peace, solidarity, unity, and love, which will play a vital role in shaping and establishing a better prosperous future for the nation.

Consumers are the king of the market as they have full liberty to choose or not to choose the specific product. In this present paper we will focus on the study of consumer purchase behavior. Consumer is considered as a user, payer and a buyer who plays important and distinct role in the market. To study the purchase behavior of the consumer, we have to take some important factors. This research paper is well focused on the progress of approach taken by the consumer behavior related to purchase. The aim of the research is to analyze the steps that affect the purchase behavior of the consumers with respect to herbal and non-herbal beauty products. The nature of the research is descriptive. Data has been collected by the researcher to perform the research with the help of secondary method and quantitative method. Non-herbal products are used less as compared to the herbal products because herbal products have a huge impact on people over non-herbal products and the consumers prefer herbal products over non-herbal products. In the latest times it is noticed that there has been an excessive growth in the market of herbal products for skin than the non-herbal products. Timescale and budget are the prime limitation of this research study. This research study is done via secondary data analysis, so it is very important to create suitable questions and select right options for questionnaire by the researcher.
A sociological study of the impact of environmental fragility on the social status of individuals: The residents of the Taghdouine El Haouz community in Marrakech as an example.
Authors: Zidan Hasna  Zidan , Alouis Mohammed
Published: January 2024

Climate and environmental changes pose a clear threat to human security worldwide, and Morocco, along with other affected countries, bears a significant portion of this climate burden. The aim of this study is to shed light on the impact of environmental vulnerability on the social situation of families in the "Tirghedouine El haouz Marrakech" community. The study focuses on key theoretical approaches that interpret concepts such as environment, fragility, poverty, and emphasizes the importance of the environmental dimension in sociological studies. In the applied aspect of the study, the main environmental threats faced by families were identified, along with an examination of all the negative repercussions of these threats on various sectors of human security and societal stability. This includes economic decline and reduced income due to the deterioration of the agricultural and tourism sectors, which are essential for the livelihoods of the population, leading to an exacerbation of instability in the region. The study also attempted to identify the most important solutions and measures taken by the population to face floods, which are characterized by their simplicity as they are individual, self-patched solutions that are insufficient to avert danger. Additionally, the study monitored the main strategies and measures adopted by local authorities to address floods, which are characterized by weakness and procrastination. In conclusion, the research results confirm that environmental threats, particularly floods, have disrupted the security and stability of the region, resulting in negative socio-economic repercussions that have affected the livelihoods and environmental, social, and economic security of the population.

Cancer is a high mortality disease of public concern. Effectiveness of chemotherapy is often limited by toxicity to untargeted tissues among other serious side’s effects. Alternative therapy such as herbal remedies for cancer, which may have the potential to offer more efficacy and less side effects have, however, not been rigorously studied or tested. The Aim of this present study therefore was to validate the anti-cancer properties (using tumor cells) of some selected Nigerian medicinal herbal remedies used by the population in Watsilla, Michika LGA. Phytochemical analysis, Antimicrobial and antioxidant activities of the selected medicinal plants were carried out as preliminary studies. The selected herbal extracts revealed the presence of alkaloid, essential oil, phenol, glycosides, flavonoid, tanin, terpenoid, proteins and saponins. The medicinal plants demonstrated good antioxidant activity with IC50 ranging from 0.42-0.54 which is lower than IC50 of Ascorbic acid (IC50 0.60 and 0.66) in both DPPH and H2O2 free radical scavenging activity model used in this study.The brine shrimp toxicity results, a preliminary anti-cancer studies, indicated that 100% of the plant extracts tested had LC50 values lower than 1000 μg/mL; Heamatostaphisbarteri (LC50 23.31μg/mL),Cyanoglossum officinal’(LC50 50.32μg/mL), Ximenia americana (LC5086.57μg/mL) and Anchus officinalis(LC50 54.37μg/mL), are excellently none toxic and surely have no obvious danger of outright toxicity during acute exposure. Thus, from the analysis it was concluded that, thesemedicinal plants demonstrated good phytochemical constituents, antioxidant activities and notoxicity on brine shrimp, with a potential to reducing the risk of tumor causing diseases, thereby confirming folkloric information of the usage of the plant as a remedy for common maladies like tumors that lead to various cancers.From the results it was found that the antimicrobial, antioxidant and antitumor activities showed better results than the standard. Bergenin has been found to have some antimicrobial, antioxidants and anti-tumor activities. Key words: Medicinal plants, pyhtochemistry, anti-tumor, antioxidant activity, chemotherapy.

This research investigated the impact of the Naira Redesign Policy on Nigeria's Economic Development by administering structured questionnaires to 800 participants across 3 Deposit Money Banks and 3 Tertiary institutions in the South East region of Nigeria. Of these, 160 respondents, representing 20%, either did not return or submitted incomplete questionnaires. Utilizing Cluster Mean Analysis based on Likert’s Five Point Scale, the study addressed its research inquiries. Additionally, it critically reviewed existing theoretical analyses related to the subject matter. The results indicate that the Naira redesign policy did not curtail illegal activities or corruption, stabilize exchange rates, facilitate easy access to production and investment loans, prevent vote buying or monitor campaign funding, lower interest rates, or increase financial inclusion while reducing the unbanked population. However, the policy did reveal currency holdings previously outside commercial bank vaults, aided security agencies in combating banditry and ransom incidents, but contributed to low savings and investment, resulting in citizen poverty. The study recommends a necessary redesign, production, and circulation of the Naira, aligning with globally accepted Central Banking standards. This call is particularly crucial considering the lack of such an exercise by the CBN for almost two decades. Moreover, this redesign process should occur concurrently with the withdrawal of the old currency. Keywords: Naira Redesign, Likert’s Five Point, Cluster Mean Analysis, Economic Development

The objective of the study was to determine the active principles present and investigate if coconut husk charcoal used in traditional ulcer management adsorbs stomach acid (0.16 M). Simple chemical tests were undertaken to test for the phytochemicals. The coconut fiber charcoal was activated with 1M and 2M KOH and H2SO4 at 500 ℃ respectively in muffle furnace. Adsorption mechanism of stomach acid was studied by the adsorption of the acid onto an activated coconut husk charcoals. Adsorption which depends on contact time, amount of adsorbent and temperature is the transfer of stomach acid to the surface was determined by titrimetric method using 0.16 M NaOH and methyl red indicator. Five phytochemicals (alkaloids, carbohydrates, tannins, saponin and glycoside) were recorded present incoconut husk extracts. The result of adsorption mechanism revealed that KOH activated coconut husk charcoal is a better adsorbent than H2SO4 activated coconut husk charcoal. The optimum contact time (minutes) and amount (g) were found to be 15 minutes and 1g respectively. Temperature was found not to have any effect on the adsorption of stomach acid. The result of this study shows that KOH activated coconut husk charcoal can be effectively used in ulcer management.

Minimization of metabolic energy expenditure in collaborative order picking
Authors: TUTAM Mahmut
Published: January 2024

Order picking is one of the most repetitive, labor-intensive, and physically demanding operations in warehouses. Picking hundreds of orders daily requires high metabolic energy expenditure and is characterized by poor ergonomics posing high risks for musculoskeletal disorders. In traditional order picking, the order picker walks around racks in a warehouse throughout the day. Alternatively, it is aimed at minimizing inefficient time and musculoskeletal strains with ride-on order picking by allowing the order picker to stand on an operator’s platform of an order-picking truck and ride the truck between stop locations. However, the order picker has to step down from the platform at each stop location and step up onto the platform before riding the truck to the next stop location. Therefore, riding the truck with frequent stops leads to more metabolic energy expenditure and musculoskeletal disorders than walking, although it is faster. Benefiting advantages of both traditional and ride-on order picking, a relatively new order picking truck (collaborative order picking truck) is deployed in warehouses to reduce inefficient walking time and ergonomic riding disorders. In collaborative order picking, the order picker can walk from a stop location directly to the next pick location while the truck moves to the next stop location autonomously or ride the truck to the next stop location in case of having a large distance between stop locations. This paper develops an optimization model to minimize total metabolic energy expenditure in collaborative order picking by finding the shortest route and the best collaboration decision (walk or ride). Based on the Monte Carlo simulation, the metabolic energy expenditure with collaborative order picking is analyzed. Our results indicate metabolic energy savings with collaborative order picking up to 200% and 83% compared to traditional and ride-on order picking, respectively.

Sign language is a primary and widely used means of communication for individuals with hearing impairments. Current sign language recognition techniques need to be improved and need further development. In this research, we present a novel deep learning architecture for achieving significant advancements in sign language recognition by recognizing isolated signs. The study utilizes the Isolated Sign Language Recognition (ISLR) dataset from 21 hard-of-hearing participants. This dataset comprises 250 isolated signs and the x, y, and z coordinates of 543 hand gestures obtained using MediaPipe Holistic Solution. With approximately 100,000 videos, this dataset presents an essential opportunity for applying deep learning methods in sign language recognition. We present the comparative results of our experiments, where we explored different batch sizes, kernel sizes, frame sizes, and different convolutional layers. We achieve an accuracy rate of 83.32% on the test set.

In the study, polymer-derived SiOC powders was synthesized by sol-gel method. The resulting composites consists of β-SiO2, SiC and free carbon. Tetraethylorthosilicate (TEOS) and Polydimethylsiloxane (PDMS) were selected as starting materials to obtain organic-inorganic structure. After the gelling process, the powders were heat treated at 1100°C in Argon medium to obtain the desired phases. Scanning Electron Microscopy (SEM), Differential Thermal Analysis (DTA) and Fourier Transform Infrared Spectroscopy (FT-IR) analyses were used for characterization. In addition, instant phase changes were determined by high-temperature XRD in powders subjected to heat treatment up to 1500 °C in a helium environment. The effect of temperatures on the transformation in SiOC synthesis, the transformation temperatures of α-cristobalite to β-cristobalite were sharply determined and the SiC formation temperature was revealed. The effect of temperature on crystal size was also obtained as a result of the study.

prilozi u Glasu Sv. Antuna (1947. – 1955.)
Authors: Lončarević Vladimir
Published: January 2024

Hrvatska književnost doživjela je završetkom Drugoga svjetskoga rata 1945. veliki politički prijelom i, nedvojbeno, duhovni lom. Znatan dio književnika zbog političkih je razloga emigrirao nastavivši književni život u inozemstvu. Godine 1947. pokrenut je pod patronatom hrvatskih franjevaca u Buenos Airesu list Glas Sv. Antuna. Glavni urednik bio je književnik Ivo Lendić. Osim vjerskih i političkih tekstova, list je objavljivao i književne: poeziju, kratku prozu, esej, književni prikaz i književnu kritiku pa je pojava takva glasila samo dvije godine nakon završetka rata značila idejno-duhovni kontrapunkt književnosti u tadašnjoj Hrvatskoj u kojoj su književnici bili pod snažnim političkim pritiskom u ime jugoslavenske ideje i komunističke ideologije. Cilj je ovoga članka evidentirati osnovne činjenice s obzirom na autorstvo i broj književnih priloga prema vrstama i žanrovima, istaknuti umjetničkim i drugima značajkama važnije među njima te utvrditi književnu relevantnost Glasa Sv. Antuna koji je tada imao ulogu reprezentanta jedne književne generacije u emigraciji, čija su djela izrazito obilježena domoljubnim duhom i kršćanskim univerzalizmom.

Authors: Espirilla Sicos Waldir Milan , Ruiz Caro David Del Castillo , Paca Pantigoso Flabio Romeo
Published: January 2024

Esta investigación aborda cómo el paradigma del gobierno abierto, enfocado en la transparencia y participación ciudadana, influye en la consolidación democrática. A nivel internacional, se identifican desafíos como la limitada participación ciudadana y falta de canales efectivos para la involucración. A pesar de iniciativas prometedoras en Europa y América Latina, problemas como la corrupción y la desconexión entre gobernantes y ciudadanos persisten. En Perú, a pesar de esfuerzos legislativos y planes de acción, se enfrentan desafíos como la infraestructura de internet insuficiente y problemas de desigualdad en el acceso a la información, especialmente en regiones como Cuzco. La investigación utiliza un enfoque cuantitativo y positivista para explorar la relación entre gobierno abierto y participación ciudadana, enfocándose en aspectos como la transparencia, rendición de cuentas y tecnología. Los resultados muestran una correlación significativa entre un gobierno más abierto y la participación ciudadana, aunque también indican que otros factores influyen en esta dinámica.
Ludificación en la geografía española. Estado de la cuestión (1980-2022)
Authors: Morote Seguido Álvaro Francisco , Hernández María
Published: January 2024

La ludificación, a pesar de ser una metodología con varias décadas de implantación, en los últimos años está teniendo un protagonismo creciente tanto en la educación en general como en la enseñanza de la Geografía en particular. El objetivo de este estudio es llevar a cabo un estado de la cuestión de las publicaciones relacionadas con la ludificación en la materia de Geografía en España (1980-2022). Metodológicamente, se ha procedido a una búsqueda bibliográfica en bases de datos (Dialnet, Scielo, Scopus, Web of Science), así como en revistas y actas de congresos específicos de enseñanza de la Geografía. Como resultado, se han obtenido un total de 4.499 publicaciones que, tras su depuración, ascienden a 76 trabajos. Las primeras publicaciones datan de la década de 1980, pero no es hasta 2017, cuando se ha producido un repunte de estas investigaciones (el 52,6% entre 2017-2022). Por tipo de publicaciones destacan los artículos en revistas de investigación (43,4%), y por temáticas: aprendizaje lúdico, aprendizaje a través del juego, actividades lúdicas, etc. (42,1%). Asimismo, en relación con la tipología de las publicaciones, predominan las que se refieren a los trabajos de propuestas didácticas (48,7%). Como conclusión, a pesar de que se ha producido un notable incremento de estos estudios, cabe destacar la complejidad en el desarrollo y puesta en práctica de los elementos lúdicos en entornos de aprendizaje tanto en la etapa escolar como universitaria, de ahí que el mayor número de contribuciones se vinculen con propuestas y no tanto con resultados de experiencias.

Authors: Mylonopoulos Foivos , Kopka Timon , Coraddu Andrea , Polinder Henk
Published: January 2024

The current state of research in marine energy systems has concentrated on conventional diesel systems, while limited literature is available on the configuration and control of alternative energy sources such as hydrogen hybrid systems, which have attracted increasing interest recently owing to the energy transition. This paper presents a modelling and control study for conceptual retrofitting of a general cargo vessel to a hydrogen-hybrid version. Generic fuel cell, battery, and converter models are used, enabling easy adaptation to various powerplant sizes and ship types. A robustly coordinated Energy Management Strategy (EMS), which can be implemented for different vessel’s power profiles, was developed for power sharing, DC bus voltage control, and battery State of Charge (SoC) regulation. The total installed fuel cell power and battery capacity were heuristically selected from a range of power profiles of the ship. A database of fuel cells with stacks from different manufacturers was created to test different combinations in terms of fuel consumption, cost, and weight, based on the framework of the problem. Uncertainties in terms of fuel prices are presented using normal distribution graphs. The system configurations and control results are presented for one power profile of the vessel and the average fuel costs. It is demonstrated that with the proposed control method, the power losses are less than 1%, the DC bus voltage fluctuations are less than 0.5%, and the battery SoC remains between 35-65% for the entire duration of the analysed power profile. The configuration with eight stacks of 150 kW has the lowest total fuel cost (730 $) with an average difference of 7.1% from the other solutions, and the lowest total weight (10.54 tons) with an average difference of 15.4% from the other configurations. Overall, this study demonstrates the efficient configuration and control of hybrid energy systems using parameterized components.
Zero-emission Fueling Infrastructure for IWT: Optimizing the Connection between Upstream Energy Supply and Downstream Energy Demand
Authors: Pourbeirami Hir M. , Kirichek A. , Pourmohammadzia N. , Jiang M. , Van Koningsveld M.
Published: January 2024

A key challenge in the energy transition for Inland Water Transport is the functional design of bunker networks and first-order dimensioning of individual bunker stations. A fundamental ingredient for this is an improved understanding of how upstream energy supply (‘well-to-bunker-station’) and downstream demand (‘bunker-station-to-tank’) may interconnect. In this paper we discuss an approach to the design of bunkering networks that takes logistic modelling to estimate network scale energy demand as a starting point. Depending on the vessels that use the network and the anticipated fuel mix for the overall fleet, logistical modelling may be used to estimate the magnitude of the energy demand along the network. Estimates of the operational range of vessels per energy carrier help to estimate maximum bunker station inter-distances. Insight into the potential supply chains that connect the source of each energy carrier to a physical bunker facility is needed to close the loop. Energy carriers may be needed on board in a gaseous or liquid form, or in the form of electrons. Transfer may take place in the form of loading (e.g., filling the fuel tank, charging the battery pack) or swapping (e.g., exchanging fuel containers, exchanging battery containers). Depending on the energy carrier, transfer method(s) and demand quantities, functional designs of bunker stations (in terms of required system elements and their order-of-magnitude dimensions) can be made. Depending on service level requirements both the dimensions of individual bunker stations and their spread over the network may be optimized. Key contribution of this work is a thorough overview of aspects that play a role in the design of bunker infrastructure for the decarbonisation of inland shipping. Based on this overview steps for further research are recommended.
QUADRAPOD Air-Assist Catamaran
Authors: Dize Andrew P.
Published: January 2024

QUADRAPOD is an air-assist catamaran hull form developed to further advance the use of surface effect ship (SES) technology. The primary advantages presented by the QUADRAPOD technology include a significant reduction in propulsion power levels and fuel consumption to achieve a given design speed, and a low-wake signature to reduce wave energy to levels lower than a conventional semi-displacement catamaran hull form. The QUADRAPOD technology is able to achieve these benefits due to the unique hull geometry which incorporates hydrodynamic lift from conventional shaped planning hulls and air cavities to provide additional lift which results in reduced wetted surface resistance. The air cavities are unique in that no flexible skirts are required to maintain cushion pressure. In addition to the hull geometry elimination of high-maintenance flexible skirts, the hull design also allows for the use of conventional propellers, water jet propulsors, or surface drive units with no air ingestion interface issues. The QUADRAPOD air-assist catamaran hull form is a US and internationally patent-pending and trademarked technology that is currently being developed for use in commercial and military vehicle/passenger ferry applications. Size applications have been studied for vessels up to 650 feet in length.
Use of Commercial CFD Codes to Enhance Performance Prediction Capabilities for Planing Boats
Authors: Scherer John , Patil S.K.R. , Morton Scott
Published: January 2024

Commercial CFD codes have become common tools for evaluating hydrodynamic performance of marine components such as propellers and appendages. The codes have traditionally been limited to submerged, single-phase flow and displacement vessels. New modeling capabilities within these codes have extended their potential application to free surface problems and cavitating or ventilated flows. Mercury Marine has been evaluating the use of these codes for analyzing planing boat performance with the inclusion of appendages, propellers, tabs/interceptors, and their interactions. Validation cases and results of this investigation will be presented with recommendations for the application of these codes.
A Look at the Impact of Filter Selection on Peak Identification of High Speed Craft Vertical Accelerations
Authors: McCue Leigh , Jacobson Don , Weil Charles , Zseleczky John
Published: January 2024

This study was motivated by the desire to rapidly identify Types Alpha, Bravo, and Charlie slam events as defined in Riley, et al., (2010a), in an automated manner. Riley, et al. observed particular characteristics of vertical acceleration in the wave slam response of high-speed craft. These characteristic acceleration responses were identified as Alpha, Bravo, and Charlie based on free fall acceleration and longitudinal acceleration peaks as described in (2010a). A numerical code was developed to identify Alpha, Bravo, and Charlie events by searching for free fall occurrences and longitudinal acceleration peaks during a slam event. The specific procedure is as follows; note steps 1-5 follow the “Standard g” approach (Riley, et al, 2010b):.
Development of Empirical Equations for Planing Craft Motions in Irregular Waves through Genetic Algorithms
Authors: Giesberg Eric , Datla Raju
Published: January 2024

An approximate and quick prediction of planing boat performance in irregular waves is useful for verifying concept designs and for seeing the effects of speed, wave height and various geometric parameters on motions. Simple, but fairly accurate for initial design, empirical equations currently only exist for estimating vertical accelerations and added resistance, but not for heave and pitch motions. The present paper studies the effect of planing boat geometry parameters, speed and wave height on the resulting motions and accelerations. A genetic algorithm, a regression method that mimics natural evolution to optimize a solution, was used to develop the empirical equations. Data sets were taken from prismatic model tests by Fridsma(1971) and Brown (1980); and a free software tool, Eureqa, was used to generate several equations for heave, pitch, accelerations at the center of gravity and bow. The equations were narrowed down by hand picking and looking at trend graphs, and the final equations were selected on the basis of simplicity, accuracy and physical correctness. The accuracy of the newly generated equation was then compared against the existing methods, Fridsma's charts for heave and pitch and Savitsky's empirical equations for accelerations. Additional validation was performed using model results from Coast Guard 47 ft. MLB standard series and a few other newer hull forms tested in the Davidson Laboratory.
Static And Dynamic Forces and Wetted Lengths for a Planing Hull Model Forced in Roll
Authors: Judge Carolyn Q.
Published: January 2024

An experimental program at the United States Naval Academy has been designed to investigate the transverse plane stability of planing hulls. An experimental mechanism to force a planing hull model in roll motion was designed and built. The first model tested was a wooden prismatic planing hull with a constant deadrise of 20o , a beam of 1.48 ft (0.45 m), and a total length of 5 ft (1.52 m). The model was forced in roll while fixed in pitch, heave, sway, yaw and surge. The tests were done at three model speeds, two displacements, three roll amplitudes, and four oscillation frequencies. In addition to the dynamic tests, the model was run at the same model speeds and displacements while held fixed in roll at seven heel angles between 0o and 30o . For both the dynamic and static roll conditions the heave and sway forces, along with the roll moment, were measured and underwater photography was taken. This paper will explore how the heave and sway forces and roll moments depend on heel angle and roll amplitude as well as how the wetted lengths (keel and chine) vary between the static and the dynamic roll conditions.

Published: January 2024

With waterways traditionally presenting the safest or the only possible route of travel, boats have been used for transportation for centuries along coastal and inland routes. At present, their significance has decreased due to development of other transport types, but transportation by small (i.e. with hull length LH≤24m) watercraft is still in high demanded for tourism and recreational activities in many holiday destinations. For remote resorts such as Maldives, islands of the Andaman Sea, Gulf of Thailand or coast of Vietnam, small water craft (fig.1) are by now the only possible means of transport. Among the tourist boats are traditional local watercraft that evolved without proper engineering (fig.2). It is an interesting exercise for any boat designer to look at local boat types as a genesis of perfectly functional and authentic style that survives in today’s mass production. Unfortunately, the lack of safety regulation and inspection result in many of these craft being built and operated under lower safety standards.
Perspectivas filosóficas e implicaciones del constructivismo como modelo epistémico para la educación
Authors: Sánchez Molina Carmen Eloísa
Published: January 2024

El mapa de contenido desarrollado en este artículo contiene varios aspectos esenciales y susceptibles de estar inacabados debido a la enorme complejidad que implica el tema en cuestión. La visión del constructivismo se remonta a los presocráticos, en sus escritos existen evidencias que el hombre construye el conocimiento como sucede con Jenófanes en sus poemas, pero también en la edad moderna están Descartes, Galileo, Newton y Kant. Posteriormente, se desarrolla el constructivismo de manera formal a través de principios y conceptos propios que tienen su influencia desde la psicología a la educación. Así, entran en escena Piaget, Vigotsky, Foerster y Glasersfeld quienes consideran de manera diferente como se construye el conocimiento. En correspondencia con lo planteado, el propósito de este artículo es interpretar el constructivismo desde la antigüedad griega hasta llegar nuestros días con sus aportes a la educación. Se concluye que el conocimiento se puede construir, el estudiante es un ente activo y el docente debe generar estrategias que permitan desarrollar la construcción del conocimiento por parte del estudiante. Igualmente, se concluye que en la edad moderna los experimentos desarrollados por Newton y Galileo sirvieron de pauta para la construcción de hipótesis y comprobación de teorías.
El hilo indivisible pedagogía, filosofía y sociología en la educación

Published: January 2024

El artículo realiza un análisis a la relación que existe entre la pedagogía, filosofía y sociología. Los problemas de la educción se abordan desde la pedagogía. Pero, los principios de la educación se establecen desde la filosofía de la educación, de esa reflexión teórico-práctico de la pedagogía, sobre el sentido de la educación. No obstante, cuando es necesario ir hacia un análisis del sistema educativo como realidad social desde esas interacciones que existen con las partes de ese sistema global que es la sociedad; se tiene recurrir al estudio sociológico de la educación para lograr ese objetivo. Estos elementos están contenidos en el presente artículo.

Published: January 2024

This study aimed to explore the impact of Thai street food on the sense of adventure and cultural immersion among first-time visitors to Thailand. Using a cross-sectional design in authentic public street settings, participants were surveyed with a semi-structured questionnaire to gather their perspectives. Thematic analysis revealed five main themes: distinctiveness, economic value, service, regulation, and locality, which were categorized into two overarching constructs: Thai street food as a unique experiential journey and its social significance. The findings provide valuable insights into the dining experiences of Chinese tourists visiting Thailand for the first time, enriching the fields of gastronomy tourism and food sociology. The study offers practical recommendations for businesses, industries, and public authorities based on its outcomes. It focuses on the unique character of Thai street food and its impact on first-time visitors, showcasing how it fosters adventure and cultural immersion in authentic street settings.
Did the Israeli Supreme Court Kill the Constitutional Coup?
Authors: Gross Aeyal
Published: January 2024

On January 1, 2024, the Israeli Supreme Court struck down a constitutional amendment prohibiting judicial review of actions of the government, the prime minister, or any minister based on the “reasonableness” doctrine. The judgment illustrates how societal and judicial vigilance in recognizing “early warning” signals of potential “constitutional capture” may play a significant role in battling such processes. However, notwithstanding this judgment and the halting of the legislative process, the threat of democratic backsliding in Israel persists. The ongoing war has, in fact, paved the way for further anti-democratic measures, some of which were upheld by the very same Court that struck down the anti-reasonableness amendment.

Con la finalidad de conocer la respuesta de seis líneas de maíz al efecto de D-N P-K (D = densidad de población), se estableció un experimento durante el ciclo primavera verano de 1995, en terrenos del CECOT, bajo condiciones de temporal. Se utilizó un diseño experimental de bloques al azar, en parcelas divididas con dos repeticiones. El arreglo de los tratamientos fue un factorial completo 24. Las líneas LE-36, LE-37, LRB 14, D-539, POB 21 y POB 43 constituyeron las parcelas grandes y las parcelas chicas fueron los tratamientos derivados de los factores D (densidad de población) a 50 y 62.5 mil plantas por ha, N, P y K a 161-184, 46-69 y 0-60 kg ha-1, respectivamente. Los análisis de varianza para líneas mostraron significancia en 14 características agronómicas, incluido el rendimiento de grano. La densidad alta aportó el mayor rendimiento de grano con 4083.3 kg ha-1. Con respecto a la interacción líneas x tratamientos, se encontró que todas las líneas incrementaron su rendimiento de grano cuando se utilizó un mayor número de plantas por unidad de área, sin embargo, no hubo respuesta de éstas para la misma variable con la dosis alta de NP, y sí una diferente exigencia nutricional de las líneas a la aplicación individual y conjunta de ambos macronutrimentos en sus dos niveles respecto a las características del grano. Con la fertilización potásica se benefició el peso volumétrico de LE-36, LE-37 y POB 43.
Desempeño de Implementos de labranza en términos de consumo de energía y calidad de trabajo

Se efectuó la evaluación del desempeño tecnológico del multiarado, y del vibrocultivador, (ambos pertenecientes a un sistema de labranza vertical) para comparar resultados tecnológicos con arado de discos y rastra de discos (labores convencionales en el estado de Coahuila), a partir de la calidad y consumo de energía que los implementos desarrollan al labrar el suelo. El experimento se estableció en un suelo arcilloso, en un diseño de bloques al azar con seis tratamientos y tres repeticiones. En el desempeño de la configuración tractor-implemento se encontró que los tratamientos con vibrocultivador y rastra tienen una mayor capacidad teórica, un menor consumo de combus tible por área, así como un menor requerimiento de potencia, por lo que estadísticamente son diferentes a los tratamientos de arado y multiarado. En la calidad y energía de la operación de los implementos se determinó que el tratamiento de rastra supera significativamente al de rastra después de arado; este último presentó un incremento en la densidad en vez de una disminución. El multiarado dejó los agregados más grandes y el vibrocultivador los más pequeños. También se encontró que en el índice energético y el esfuerzo unitario de los tratamientos de arado de discos y multiarado existe diferencia con el resto de los tratamientos; asimismo, el arado de discos supera al multiarado en un 32 y 25.5 % con relación al índice energético y esfuerzo unitario, respectivamente. La diferencia del esfuerzo de cada implemento la influencian su forma geométrica, la intensidad del corte y la manipulación que hacen del suelo.

Con el objetivo de generar alternativas que favorezcan la extensión de vida en anaquel del tomate (Lycopersicon esculentum Mill) cv. Floradade, se estudiaron los efectos de diferentes temperaturas en el contenido de etileno, PG y ACC, durante el ciclo productivo primavera-verano 2001. Los frutos cosechados se almacenaron a temperatura ambiente (testigo) y a 7 y 9 °C. Las evaluaciones se empezaron a realizar seis días después de estar en esas condiciones. Se estudiaron las variables: peso, firmeza, sólidos solubles, almidón, etileno, cantidad de ácido-1-aminocilopropano-1-carboxílico (ACC), poligalacturonasa (PG) y vida de anaquel. Los frutos que se sometieron a temperatura de 7 °C mostraron mayor peso y firmeza; a temperatura ambiente, los frutos presentaron mayor contenido de °Brix y menor de almidón. La producción de etileno, ACC y PG fue menor en los frutos tratados a temperatura de 7 y 9 °C; su vida de anaquel se prolongó substancialmente al compararlos con los que se conservaron a temperatura ambiente. Se concluyó que las temperaturas de 7 y 9 °C provocaron menor contenido de etileno, ACC y PG, lo cual prolongó por más días la vida de los frutos de tomate cv. Floradade.
