Effect of Palm Oil Wastes Soil On Crop Germination in Ogodo, Kogi State
Authors: Egu Dr. Samuel Attah , Momoh Theophilus Boniface , Iyeh Veronica Amina
Published: April 2024

The study looked into how different soil properties and Amaranthus hybridus growth were affected by palm oil wastes. Comparing the contaminated soil with the control sample, physico-chemical examination showed that the contaminated soil had greater amounts of Na, K, Mg, Ca, TEB, EA, ECEC, AP, WHC, pH, OC, and TN. Particle size measurement revealed differences in the amounts of silt, clay, and sand; samples closer to the dumpsite and in the vicinity were primarily classified as sandy clay loam, whereas those farther away were classified as sandy loam. The palm oil waste soil had a substantial impact on the germination count and growth characteristics of A. hybridus, with greater counts and growth noted in contaminated soil compared to control. Significant effects were also observed in antioxidant activity, with the dumpsite showing the strongest suppression of DPPH radicals. Furthermore, there were notable differences in the proximate and mineral elements of A. hybridus. Plants grown in soil contaminated with palm oil waste were found to have higher levels of protein, ash, fiber, moisture, carbohydrates, and lipids than the control. The contents of soil samples differed in terms of calcium, iron, potassium, and phosphorus, but there was no discernible difference in sodium and zinc. The study's overall findings demonstrate the profound effects of palm oil wastes on the physico-chemical characteristics of soil, plant growth, and nutritional value.

Published: April 2024

Passive radiative cooling coating, PolyCool, has been developed with a solar reflectance of 97.4% and emissivity at the atmospheric window of 91%. This coating utilizes porous polyethylene, characterized by a broad pore size for enhanced solar reflectance, and incorporates PDMS nanoparticles to augment emissivity at the atmospheric window. A method that enables the scalable and size-controlled synthesis of PDMS nanoparticles has been established. Additionally, a technique for creating a porous structure coating using low-density polyethylene has also been developed. The microstructure and coating thickness can be precisely controlled throughout the coating process. In comparison to traditional methods for manufacturing superhydrophobic surfaces, our approach allows for the rapid preparation of a pure polyethylene-based surface with minimal equipment and material costs. The coating could also be deposited flexibly on various substrates, including metal.

There are studies which indicate that some sulfonamide derivatives can produce changes in the cardiovascular system; however, their biological activity on perfusion presure and coronary resistance is not clear. The aim of this research was to evaluate the effect exerted by benzenesulfonamide, and  their derivatives (2,5-dichloro- N-(4-nitro-phenyl)-benzene-sulfonamide, 2-hydrazino-carbonyl-benzenesulfonamide, 4-(2-amino-ethyl)-benze- ne-sulfonamide, and 4-[3-(4-nitro-phenyl)-ureido]-benzene- sulfonamide) on perfusion pressure and coronary reistance.  To evaluate the biological activity of benzenesulfonamide and their derivatives on perfusion pressure and coronary reistance an isolated rat heart model was used. Furthermore, theoretical interaction of 4-(2-amino-ethyl)-benzenesul- fonamide with Calcium channel surface was determined using 6jp5 protein, nifedipine, amlodipine, verapamil and BayK 8644 as theoretical tools in a DockingServer program. The Results showed that 4-(2-amino-ethyl)-ben- zenesulfonamide decreased perfusion pressure and coronary resistance compared to benzenesulfonamide, 2,5-dichloro- N-(4-nitro-phenyl)-benzene-sulfonamide, 2-hydrazinocar- bonyl-benze-nesulfonamide, 4-[3-(4-nitro-phenyl)-ureido]- benenesulfonamide and the control conditions. Besides, theoretical data suggest that 4-(2-aminoethyl)benzenesulfo- namide could interact with aminoacid residues such as Glu614 and Ala320 involved in 6jp5 protein surface. This phenomenon could result in an ligand-Calcium channel  complex  formation to produce a decrease in perfusion pressure and vascular resistance. It is noteworthy that  biological and experimental  models used in this study is an invaluable research tool for investigating questions across the spectrum of physiologic functions of cardiovascular system such as perfusion pressure and coronary resistance
“How do I tell the story?”: Exploring sexual harassment and victimization among male students in Nigerian universities
Authors: Anugwom Kenechukwu Nwakego
Published: April 2024

The paper investigated the phenomenon of sexual harassment in tertiary institutions in Nigeria. It however differs from the well-trodden path of perceiving sexual harassment as limited to the female gender. Sexual harassment is an old phenomenon that has ravaged societies and institutions for decades but has not yet been fully comprehended as a problem afflicting both genders in the society. Conventionally, sexual harassment was perceived as tool used by men to exhibit dominance over women. Incidentally, the paper utilizing qualitative methods of study discovered that even men (mainly male students and men in lower positions in organizations) experienced sexual harassment at one point or another in their lives. It also found out that these experiences are hardly reported or investigated. This situation derives mainly from the patriarchal nature of the African society where men are not socialized to express their pains and emotions openly as the society sees men as the stronger gender. In view of the foregoing, the paper makes a strong case for the utilization of social work approach among other strategies in tackling the problems faced by these silent victims of sexual harassment in tertiary institutions.

Introducing technologies into national large-scale testing: Are we ready?
Authors: Cipriano Gabriel , Martins Susana da Cruz
Published: April 2024

In recent decades, the potential benefits of introducing technologies into large-scale tests have been much discussed. Yet the path to effective technology use on large-scale testing has fallen short of expectations, especially when these tests have medium or high stakes for students. After a temporary cancelation of external assessment of learning due to the COVID-19 pandemic, the Portuguese government is taking a step forward. With a gradual implementation until 2025, the reintroduction of external assessment of learning in the Portuguese education system foresees all national assessment tests and all national examinations in digital format with the implementation of the External Assessment Dematerialization Project (DAVE). However, assessment reforms, such as DAVE, raise concerns within school communities. To identify and analyze these concerns, we conducted 32 semi-structured interviews with head teachers from mainland Portugal. To understand to what extent these concerns were considered and covered in DAVE’s design and implementation, a supplementary interview was conducted with the president of the Portuguese institute responsible for DAVE. In addition, a survey with 2 673 teachers was carried out to find out their degree of agreement with the implementation of DAVE. Results show that DAVE raises many concerns among head teachers, and it is not fully accepted by the teachers.
Area Studies in the Social Sciences
Authors:   Freie Universitat Berlin, Libman Alexander
Published: April 2024

In the last decades, area studies have been subject to substantial criticism by the most mainstream social sciences. Area specialists are perceived as lacking the knowledge of modern research methodology and rather following the interests of humanities than social sciences. At the same time, studying individual regions and countries certainly requires the accumulation of specific knowledge, which would most likely be lost without area studies research. This paper discusses the main directions of criticism of area studies and possible suggestions towards modernization of this research tradition. The criticism towards area studies can be linked to three issues: the excessive dominance of the humanities in most area studies communities; insufficient consideration of modern theoretical and empirical approaches; and implicit normativity, i.e., the substitution of scientific analysis with value assertions. The modernization of area studies as an academic field is related to the application of alternative approaches to regional and country studies within three research projects: Comparative Area Studies (CAS), Transregional Studies, and regional specialization within individual disciplines

Published: April 2024

Kota Semarang merupakan Ibu Kota Provinsi Jawa Tengah yang berada di dataran rendah dan tercatat total jumlah kejadian bencana banjir menurut BPBD Kota Semarang selama tahun 2022 yaitu dengan total 63 kejadian banjir. Semakin tingginya tingkat bencana banjir di Kota Semarang, maka semakin tinggi juga kapasitas yang harus dimiliki oleh Kota Semarang dalam menghadapi banjir. Upaya pemetaan kapasitas banjir, penting untuk dilakukan untuk mengetahui sejauh mana kesiapan Kota Semarang terhadap bencana banjir, baik dari komponen fisik, kesehatan, pendidikan, sosial, lingkungan, dan ekonomi. Pada penelitian ini, pemetaan dan analisis tingkat kapasitas banjir di Kota Semarang dilakukan menggunakan metode Principal Component Analysis (PCA). Metode PCA dapat menentukan tingkatan kapasitas banjir di Kota Semarang dengan mengelompokkan variabel – variabel atau parameter penentu tingkat kapasitas banjir yang tidak memiliki korelasi antara setiap variabelnya menjadi bentuk variabel baru yang dapat mewakili rangkaian informasi dari variabel asli atau dapat disebut dengan komponen utama. Tingkat kapasitas banjir dihitung menggunakan nilai varians kumulatif dari komponen utama yang terbentuk dan menghasilkan 3 kelas kapasitas yaitu Kapasitas Rendah yang berisi 1 Kecamatan, Kapasitas Sedang yang berisi 13 Kecamatan, dan Kapasitas Tinggi yang berisi 2 Kecamatan. Peta kapasitas menggunakan perhitungan PCA kemudian dihubungkan dengan peta ancaman dan kerentanan dari BPBD Kota Semarang untuk menntukan tingkat risiko. Hasil dari perhitungan risiko diperoleh wilayah dengan tingkat risiko rendah seluas 28392,126 Ha, atau sekitar 72,045%, tingkat risiko sedang memiliki luas sebesar 6510,210 Ha, atau sekitar 16,520%, dan tingkat risiko tinggi memiliki luas sebesar 4506,334 Ha atau sekitar 11,435% dari total luas wilayah Kota Semarang.

Abstract: Despite the fact that lean construction (LC) has been shown to increase construction safety, little research has been done been carried out to investigate how LC technology can be applied to safety management. This the study aims to close this gap by developing a safety planning and control (SPC) process based on LC technology and evaluate it using a structural equation model. The process is based on the final planner system research framework (LPS) and consists of four sub-systems (ie, analysis layer, planning layer, control layer, and performance layer). Data was collected from 150 projects HSE employee at building construction in the Jakarta area. These findings will serve as a guide for construction stakeholders looking to improve efficiency safety management by incorporating some LC technology into the SPC process. And four subsystems work together to create a positive circulation system that aids long-term improvement construction safety management.
TRILOCK BRICK : INOVASI DESAIN BATAKO BENTUK SEGITIGA DENGAN SISTEM INTERLOCK
Authors: Ningtiyas Ubbidah Agus
Published: April 2024

As the construction industry in Indonesia continues to grow, it has significantly impacted the demand for building materials, particularly in the construction sector. One such material is "batako," which is used as a wall filler, along with cement as a bonding material (grout). Therefore, there is a need for a solution that provides easier workability during installation and is cost-effective. The objective of this research is to innovate and analyze the design of triangular-shaped batako with an interlocking system on each side. The methodology used involves experimental testing in a laboratory and follows the Indonesian National Standard (SNI) 03-0349-1989. The process includes material testing, specimen production, compressive strength testing, absorption testing, and a cost comparison analysis. The research resulted in the development of "trilock brick," a triangular-shaped batako measuring 36 cm in length and 9 cm in thickness. The average compressive strength at 28 days was 9,487 MPa, with an average water absorption rate of 5.344%. The installation cost per 1 m2 was Rp. 76,802, with a grout thickness of 0,5 cm. This research demonstrates that this innovation possesses compressive strength and water absorption values comparable to conventional batako. Additionally, trilock brick offers economic advantages with a cost difference of up to 13% compared to conventional batako requirements.

Published: April 2024

Objectives

Secretoneurin (SN) is a novel cardiac biomarker that associates with the risk of mortality and dysfunctional cardiomyocyte Ca2+ handling in heart failure patients. Reference intervals for SN are unknown.

Methods

SN was measured with a CE-marked ELISA in healthy community dwellers from the fourth wave of the Trøndelag Health Study (HUNT4) conducted in 2017–2019. The common, sex and age specific 90th, 95th, 97.5th and 99th percentiles were calculated using the non-parametric method and outlier exclusion according to the Reed test. The applicability of sex and age specific reference intervals were investigated using Harris and Boyd test. We also estimated the percentiles in a subset with normal findings on echocardiographic screening.

Results

The total cohort included 887 persons (56.4 % women). After echocardiographic screening 122 persons were excluded, leaving a total of 765 persons (57.8 % women). The 97.5th percentile (95 % CI in brackets) of SN was 59.7 (57.5–62.1) pmol/L in the total population and 58.6 (57.1–62.1) pmol/L after echocardiography screening. In general, slightly higher percentiles were found in women and elderly participants, but less than 4 % in these subgroups had concentrations deviating from the common 97.5th percentile. Low BMI or eGFR was also associated with higher concentrations of SN.

Conclusions

Upper reference limits for SN were similar amongst healthy adult community dwellers regardless of prescreening including cardiac echocardiography or not. Women and elderly showed higher concentrations of SN, but the differences were not sufficiently large to justify age and sex stratified upper reference limits.

Published: April 2024

Naegleria fowleri is a free-living amoeba that causes primary amoebic meningoencephalitis. Despite combination drug therapies, N. fowleri is not sensitive to current drug therapies, contributing to the pathogen’s mortality rate of 98%. To enable rational drug designing, this study has proposed an integrated track of nanotechnology coupling with the enrichment concept. In the current study, zinc oxide nanoparticles (ZNP) were screened against ERK protein, which is responsible for the production of pro-inflammatory cytokines that cause brain disturbance in N. fowleri infection. Furthermore, an enrichment analysis has been executed to increase the efficiency of the ZNP through the addition of two amines and one chlorine group. The computational prediction of zeta potential, cytotoxicity, organ toxicity, calculations of binding free energy, and ADMET analysis shows that it is stable and possesses no toxic effect. Amine + chlorine enriched ZNP resulted in a binding energy of −7.8 kcal/mol, a zeta potential reliability of −40 mV, a cytotoxicity of −0.0002, inactive against all the targeted organ models, ADMET profiling shows a molecular weight of 320.54 g/mol, a lipophilicity of −0.99, high water solubility, and good gastrointestinal tract absorption. This proposed invention represents the future work for in vitro in combating this devastating disease toward a reliable therapeutic target with drugs that specifically aimed to inhibit the infection.

Authors: Enescu Adrian-Gabriel , Raileanu Szeles Monica
Published: April 2024

This study contributes to the literature on portfolio choices of elder persons by examining the influence of digital literacy on the propensity to own risky assets, when considering individual- and country-level variables. Our empirical analysis is based on data from Survey of Health, Ageing and Retirement in Europe and a set of macroeconomic indicators retrieved from international databases. To capture the impact of individual- and country-level factors, we have utilized multilevel models with a two-level sampling design. The results obtained provide evidence for a positive relationship between individual- and country-level digital literacy and portfolio riskiness, as well as heterogeneity in the portfolio choices of older individuals across the European Union (EU) countries. In addition, age is found to influence differently the portfolio riskiness of elder persons across the EU countries. Bridging the digital divide may provide access to balanced-risk portfolios for elderly persons.
Obliquity-paced summer monsoon from the Shilou red clay section on the eastern Chinese Loess Plateau
Authors: Xu Silu , Chen Jiasheng
Published: April 2024

The red clay of the Chinese Loess Plateau (CLP) is an important geological archive for understanding the variability in the late Neogene East Asian monsoon. The periodicity of the summer monsoon of the red clay on the eastern CLP is dominated by eccentricity cycles within the constraints of the palaeomagnetic chronological framework, whereas global climate change characteristics represented by the deep-sea oxygen isotope record at that time show a dominating obliquity cycle. Here, we analyzed the East Asian summer monsoon proxies from the Shilou red clay section with the cyclostratigraphy method. The results show that the summer monsoon variation was dominated by obliquity, the optimum deposition rate was 4.451 cm/kyr, and the floating age of the Shilou red clay section was ca. 1.7 Ma. The late Neogene East Asian summer monsoon inferred from the eastern CLP was thus paced by the obliquity cycle, which is consistent with global change.
Humor, emotion, and interpretive communities in the controversy over Jerry Springer: The Opera
Authors: Martin Paul S
Published: April 2024

Satires that tackle religion have always courted controversy. When Jerry Springer: The Opera was originally aired on the BBC in 2005, the show received 63,000 complaints and Christian Voice attempted to prosecute Mark Thompson (the Director General of the BBC) for blasphemy for airing the show. In this article I draw on the work of Stanley Fish and Gerben van Kleef to argue that interpretive communities of emotional readers provide a valuable framework for interpreting humor scandals. This framework contributes to our appreciation of the interpersonal in the emotional experience of humor and demonstrates that interpretations of humor are often goal-oriented and ideologically motivated. Using the examples of Christian Voice and Mediawatch-UK, I demonstrate how these emotional communities are constructed as well as the rhetorical strategies these organizations adopted. To accuse Jerry Springer: The Opera of blasphemy, for example, Christian Voice presented themselves as defenders of traditional British values. Finally, my analysis of these examples demonstrates that the potential for community outrage increases especially when the community faces a crisis of identity.
CFD-DEM simulation of chemical looping hydrogen generation in a moving bed reactor

Published: April 2024

Chemical looping hydrogen generation represents a viable technology for high-purity hydrogen production and CO2 capture. Moving bed reactors are considered effective for this process, but the high cost of experiments and the complexity of the biomass gas reaction have hindered the development of hydrogen generation from biomass gas.This investigation employs Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) to simulate gas-solid phase distribution and reactions within a moving bed fuel reactor, aiming to amplify biomass gas and oxygen carrier conversion rates. Findings indicate that enhancing particle flux rate and reaction temperature substantially increases the conversion efficiency of both biomass gas and oxygen carrier. Notably, achieving complete CH4 conversion presents significant challenges in biomass gasification, with CH4 conversion dictating the requisite bed height for total biomass gas conversion. Furthermore, the gas-phase equilibrium conversion rate of Fe3O4 to FeO delineates the operational limit within the moving bed. Under full reaction conditions of biomass gas, the oxygen carrier’s maximum achievable conversion ranges between 29.2  and 31.6 % at 850 °C. These insights substantially advance the application of biomass gas in the chemical looping domain and inform future design and operational strategies for reactors.
Establishing the limits between polarity sensitivity, negative polarity and negative concord
Authors: Etxeberria Urtzi , Espinal M.Teresa , Tubau Susagna
Published: April 2024

In this paper, by focussing on the behaviour of polarity elements from a variety of languages from different language families (namely, Basque, Hindi, English, Romanian, Spanish, Greek, Czech, and Russian) we investigate the relationship between polarity sensitive items (PSIs) and negative polarity items (NPIs) on the one hand, and between PSIs and negative concord items (NCIs) on the other. Based on a number of contrasts that we find, we argue that: (i) if a language has PSIs it does not necessarily have NCIs; (ii) PSIs need to be distinguished from NPIs; (iii) NCIs emerge as a subtype of PSIs, not of NPIs; and (iv) all languages that show negative concord (NC) also have polarity sensitivity (PS), but the opposite does not hold. We thus postulate that PS is a general phenomenon across languages with negative polarity (NPol) and NC as possible subtypes of PS but independent among them, and argue against the standard hypothesis that NC is a special subtype of NPol.
Computational study on reactivity, aromaticity, and absorption spectra of chrysene: effect of BN doping and substituents
Authors: Saha Bapan , Bhattacharyya Pradip Kr.
Published: April 2024

Density functional study (DFT) is performed for understanding the reactivity, aromaticity, and UV-visible absorption spectra of chrysene-based materials. Effect of BN doping on the said parameters are analyzed along with the effect of –Me (methyl), –OH (hydroxyl), –CHO (formyl) –COOH (carboxyl) and –CN (cyano) substituents. Global reactivity parameters viz. energy of HOMO (E
HOMO), global hardness (η), chemical potential (μ) and electrophilicity (ω) are computed. Nucleus independent chemical shifts (NICS) values are estimated to study the variation in aromaticity. Time dependent density functional theory (TD-DFT) is used to study the UV–Visible absorption spectra. Effects of BN doping and substituents on corresponding dipole moments and band gaps are also analyzed. Presence of BN unit and/or substituents induced considerable impact on global reactivity, dipole moment, band gap and aromaticity of the chosen systems, especially for BN doped chrysene at the edge. Absorption spectra which are red shifted in presence of BN and substituents are mostly found within the UV-region.
Amyopathic dermatomyositis may be on the spectrum of autoinflammatory disease: A clinical review
Authors: Sharmeen Saika , Christopher-Stine Lisa , Salvemini Joann N. , Gorevic Peter , Clark Richard , Yao Qingping
Published: April 2024

Systemic autoinflammatory diseases (SAIDs) are distinct from autoimmune diseases. The former primarily results from abnormal innate immune response and genetic testing is crucial for disease diagnosis. Similar cutaneous involvement is a main feature for both SAID and dermatomyositis (DM), so they can be confused with each other. A literature search of PubMed and MEDLINE was conducted for relevant articles. The similarities and differences between these two types of diseases were analyzed. We found phenotypic similarities between these two types of disorders. Accumulating data supports a major role of the innate immune system and a similar cytokine profile. Molecular testing using an autoinflammatory disease gene panel may help identify SAID patients from the DM population and may offer therapeutic benefit using interleukin-1 (IL-1) inhibitors. A subset of DM, notably amyopathic dermatomyositis in the absence of autoantibodies may be on the spectrum of autoinflammatory disease.
Critical comments in the disciplines: a comparative look at peer review reports in applied linguistics and engineering
Authors: Kashiha Hadi
Published: April 2024

Critical comments have shown to figure prominently in determining the fate of manuscripts submitted to reputable journals. While various studies have explored different facets of this evaluative genre, there has been limited examination in the context of second language and disciplinary writing. Using a discourse analytic approach, this study analyzed a corpus of 160 reviewers’ reports on submissions by Iranian nonnative writers in applied linguistics (AL) and engineering. The aim was to compare how reviewers employ different categories of critical comments to prompt writers to revise their submissions. The findings revealed that reviewers, regardless of discipline, more frequently commented on language-use issues than content-related issues. Among language-use comments, issues pertaining to lexical and syntactical usage of English were more prominent than concerns about discourse and rhetoric. The analysis also indicated consistent patterns in the reviewers’ reports regarding discourse organization and the balance between positive and negative feedback. These findings are discussed in terms of their practical implications for novice and nonnative researchers in the examined fields, offering insights into the rhetorical and disciplinary norms governing peer reviews and the linguistic choices made by reviewers to guide authors throughout the review process. Increased awareness of these issues can facilitate more effective responses to reviewers’ feedback.

The Romanian deadlift (RDL) is a useful exercise to isolate and train primarily the hip extensors in a weight-bearing stance, but anterior-posterior instability is a limitation that warrants exploration to improve the exercise. The landmine Romanian deadlift is a modification of the RDL that provides greater anterior-posterior stability. This difference in stability has the potential to minimize error in technique, improve muscle activation and force output, and reduce the risk of injury.

Authors: Baumeister Elena , Berg Fiona , Eitelbach Charlotte S. , Holzberger Sophie , Purkpong Arisa
Published: April 2024

feminist elsewheres takes the question of an elsewhere of feminist film history as a foundation of its engagement with two events that took place at the Arsenal cinema in Berlin: the First International Women’s Film Seminar in 1973, which is considered the starting point of the feminist film movement in West Germany, as well as its 1997 revisitation titled…the point is to change it. Films, Festivals, Feminism. In 2023, feminist elsewheres celebrated over fifty years of feminist film work with a film program, workshops, and an exhibition. This text is collectively authored by feminist elsewheres and its objective is twofold: introducing the historical present of these events while at the same time reflecting on feminist modes of collaborations as central strategies in shaping film history. No film stands alone, No history is stable, feminist elsewheres is many.
Curation as the Cure for the Archive
Authors: McLeod Dayna , Olibet Ylenia , Thain Alanna ,   In collaboration with Groupe Intervention Vidéo
Published: April 2024

Groupe Intervention Vidéo (GIV) is an independent artist run center in Montreal “dedicated to the promotion of videos created by women (in its most inclusive definition) by distributing and presenting them” (GIV website) At the crossroads of longevity, consistency, commitment, and the precarity that accompanies most forms of feminist labor, GIV is one of the most important “accidental” archives of feminist organizing and expression in Quebec. Their curatorial practices resist any archiving separated from the practice of everyday life. This article focuses on the thirty-year history of Vidéo des Femmes dans le Parc (VFP), GIV’s annual public and outdoor screening of new works from an open call. We trace how this event serves to “call in” artists to build feminist community and continually change GIV’s definition of who their community is.
The Work of Care
Authors: Kim Hieyoon
Published: April 2024

This essay examines feminist curation as a work of care with the example of Purplay, a South Korean streaming service. In less than four years since its official launch, Purplay has grown into a platform that currently streams 330 films made by women, hosts a community of 30,000 subscribers, and produces new discourse on women’s cinema through its various initiatives. I analyze an array of Purplay’s curatorial practices as a feminist intervention that not only provides increased access to women’s films but also forges a sense of community among the platform’s participants. These practices, I argue, have constituted a sober reckoning with the inequitable dynamics that characterize South Korea’s current social fabric, and are redefining its screen culture.
El montaje cinematográfico y la memoria
Authors: Rodríguez Arévalo Diego Mauricio
Published: April 2024

El método desarrollado por Serguei Eisenstein, a través del cual logra encadenar y dar sentido a una serie de planos cinematográficos, pone de manifiesto la importancia del montaje, en tanto que permite revelar sensaciones y afectaciones, es decir, un pathos que hace referencia a intereses vitales, miedos, deseos y nostalgias de diferentes lugares y épocas que irrumpen de manera fulgurante en forma de imagen. En términos de la memoria, existe de manera similar un montaje de imágenes, por medio de las cuales se representa el pasado. Por tanto, el presente artículo desarrolla algunas reflexiones acerca de la película El acorazado Potemkin, y a su vez plantea la posibilidad de trasladar una serie de características del montaje Eisensteniano a los procesos de la memoria.
Políticas Turísticas en Temoaya Estado de México: análisis mediante el Enfoque de Redes de Política Pública
Authors: Salazar Mondragón Gustavo , Cruz Jiménez Graciela , Ramírez Hernández Omar Ismael , Castillo Nechar Marcelino
Published: April 2024

En México históricamente las políticas turísticas se orientado al turismo de sol y playa; no obstante, desde hace algunos años han emergido proyectos enfocados al desarrollo de espacios con otras cualidades, a fin de alentar alternativas recreativas, generar nuevos empleos y mejorar la calidad de vida de su población a partir de diversificar la economía, revalorizar el territorio, preservar el ambiente y evitar la migración. Uno de esos destinos es Temoaya, municipio con importante patrimonio natural y cultural heredado de su tradición otomí, cuyas políticas turísticas no han alcanzado los resultados deseados. Este artículo tuvo como objetivo develar los principales motivos, entre los que sobresalen deficiente planeación, falta de conocimiento del personal e intereses individuales de los actores vinculados a este fin. El soporte teórico-metodológico de esta aproximación fue el Enfoque de Redes de Política Pública que posibilitó identificar de qué manera se orientaron las políticas a favor del turismo entre los años de 2019 a 2023. Se concluye que priorizar la promoción, el crecimiento de la infraestructura, y al sector artesanal, ha limitado el pleno aprovechamiento del patrimonio natural y la atención de problemas como la pobreza mediante el turismo.
Las humanidades digitales: transgresión e indisciplina
Authors: Santofimio Rojas Germán Andrés
Published: April 2024

El artículo de reflexión examina el carácter de las humanidades contemporáneas en el contexto de la era digital y globalizada. Se destaca su capacidad para integrar diversas perspectivas culturales y tecnológicas, lo que refleja su importancia en la construcción de una comprensión crítica y contextualizada de la realidad. A pesar de enfrentar desafíos, como la presión utilitaria y la priorización de disciplinas, las humanidades contemporáneas pueden aprovechar estas presiones como oportunidades para abordar cuestiones éticas y sociales. Asimismo, se resalta el cambio hacia un enfoque transdisciplinario en las humanidades contemporáneas, rompiendo barreras tradicionales para abordar problemas complejos que trascienden fronteras académicas convencionales. Además, destaca el papel crucial de las humanidades en la sociedad actual al proporcionar una comprensión profunda de la condición humana y sus complejidades, facilitando la empatía y la comprensión intercultural. Finalmente, se enfatiza el carácter transgresor e indisciplinado de las humanidades, como una fuerza impulsora para mantener su dinamismo y relevancia al desafiar las normas preexistentes y ampliar los límites del conocimiento.
Un acercamiento al populismo como herramienta para el análisis de mandatos y campañas políticas en Colombia
Authors: Orozco Macias Andrés Fernando , Madrid Garcés Pedro José
Published: April 2024

Objetivo: Analizar como a partir de la identificación de una frágil definición académica del concepto populismo, en el ámbito de América Latina y especialmente en Colombia, se desarrolla un proceso analítico-conceptual, sobre cuáles son las definiciones y aplicaciones de los conceptos en la realidad política. Métodos: El artículo plantea a través de un modelo metodológico-experimental, la posibilidad de profundizar conceptos que permitan explicar e identificar acciones o discursos populistas en el contexto colombiano. Resultados: Se encontró, que en muchas de las investigaciones se intenta definir el concepto a partir de los diferentes acontecimientos de la historia política de los países en análisis, y sobre todo, de los políticos en los que se sospecha populismo a partir de sus discursos; en consecuencia, en la aplicación de la metodología-experimental de esta investigación, se tomó autores como Zanatta (2013) y Rosanvallon (2020), en los que se identifican categorías conceptuales como: populismo como eje comunitario, populismo como centralidad y seguridad, populismo como abarcamiento de una gran mayoría con un margen de pequeñas minorías que constituyen los enemigos, a su vez surgieron unas subcategorías de emociones políticas que garantizan esas primeras, entre ellas emociones de posición, emociones de acción y emociones de intelección, todas seis conectadas respectivamente. Conclusiones: El desarrollo de conceptos que contribuyan a la explicación del fenómeno populista en campañas electorales, es clave para comprender las aristas de la cultura política y los nuevos ordenes sociopolíticos en los procesos electorales.
