Post-Internet Music: Negotiating Queer Identity in the Digital Era
Authors: Affaticati Lucia Clara
Published: July 2024

My paper investigates an electronic music genre that emerged in the 2010s, in conjunction with the rise of attention to identity politics on mainstream platforms. The genre does not have a definite name; however, attempts have been made by critics (see, for example, Waugh 2017) to categorise it under the umbrella term "post-internet music". Such a label encompasses different and often competing sub-genres, all of which nonetheless share an imbrication in internet discourse: these range from Hyperpop, to ‘Deconstructed Club, to ‘Conceptronica’ (Reynolds 2019). As such, the post-internet genre has three distinguishing features: a) many artists operating within it identify both themselves and their music as queer; b) on the sonic side, the genre often comprises complex sound design, loud mixes, a wide stereo field, organic drum samples, pitched-up vocals, and beats that elude conventional time-signatures, so as to sound "deconstructed"; c) the music often makes overt or subtle reference to internet culture, and the digital domain. I seek to place particular attention to the conjuncture between the genre's sonic properties and its ‘queerness’, arguing that the genre is both enabled by, but also enables, internet-mediated identity categories. In this sense, I question what it means to be queer in the contemporary neoliberal era, how this might historically differ from previous elaborations of queerness, and to what extent electronic music - a genre so entrenched in masculinist narratives of technology - can act as a vehicle for counter-normative expression. 
Motivación laboral en el sector cooperativo
Authors: Romero Melina , Scrivanelli Antonella
Published: July 2024

Se presenta un estado del arte sobre motivación laboral en el sector cooperativo, con foco en las cooperativas de trabajo, a partir de la revisión sistemática descriptiva de literatura académica entre los años 2012 y 2022. Se constata poca acumulación teórica, con el desempeño laboral como foco de estudio y el interés en la motivación laboral en tanto su relación con este. Las investigaciones son mayormente cuantitativas y provenientes de Asia, con escasa referencia a las teorías de motivación laboral y al cooperativismo, sin contemplar el diferencial cooperativo en los análisis de resultados, centradas mayoritariamente en los empleados de cooperativas de usuarios. Los escasos trabajos que hacen foco en las y los cooperativistas provienen de Latinoamérica y presentan factores motivacionales para estos trabajadores. Se evidencia la necesidad de investigar, desde la administración, sobre las cooperativas de trabajo, donde la particularidad de la gestión colectiva se visualiza más fuertemente.

Digital services of tourist areas—Key to competitiveness
Authors: Happ Éva , Horváth Zsuzsanna Ivancsóné , Kupi Marcell
Published: July 2024

In our study, we examined 11 designated tourist destinations in Hungary, which can also be interpreted as tourism products including services, infrastructure and attractions. The National Tourism Development Strategy (NTS) also puts a strong emphasis on digitalisation, as it is an unstoppable process with a significant impact on tourism, thanks to globalisation, increasing competition, accelerating information flows and the dominant paradigm shifts on the demand and supply side. We used both qualitative and quantitative methods in our primary research. First, we conducted in-depth interviews with several important tourism service providers in Hungary on the topic of the digitalisation of tourism. A professional questionnaire, addressed to the offices responsible for destination management was distributed in the designated tourist destinations in Hungary in order to get a more comprehensive picture of the attitudes towards digitalisation in the regions under study. In the course of our work, we managed to classify the destinations into three distinctly different clusters. Our hypothesis—that the higher the digitalisation of a tourist destination is, the higher the average length of stay—was partially confirmed by calculating the regional value of the digitalisation, logistic regression analysis, slope and the individual factor categories.

Mathematical Analysis of Chemically Reacting Species and Radiation Effects on MHD Free Convective Flow Through a Rotating Porous Medium
Authors: Sharma Pawan Kumar , Sharma Bhupendra Kumar , Kumar Anil
Published: July 2024

The present study deals with the effects of radiation and mass transfer on a laminar unsteady free convective flow of a viscous, incompressible, electrically conducting and chemically reacting fluid past a vertical surface in a rotating porous medium. It is assumed that the surface is rotating with angular velocity Ω. The governing mathematical equations are developed and solved by adopting complex variable notations and the analytical expressions for velocity, temperature and concentration fields are obtained. The effects of various parameters on mean primary velocity, mean secondary velocity, mean temperature, mean concentration, transient primary velocity, transient secondary velocity, transient temperature and transient concentration have been discussed and shown graphically. Further, the consequences of different parameters on rate of heat transfer coefficient (Nusselt number), rate of mass transfer coefficient (Sherwood number) and drag coefficient (mean skin-friction) are analysed. It is observed that the mean and transient primary velocities increase with the radiation parameter E, while reverse phenomena are observed for the Schmidt number, Sc, and the chemical reaction parameter, γ. The results may be useful in studying oil or gas and water movement through an oil or gas field reservoir, underground water migration, and the filtration and water purification processes.
Testing the Thermal Properties of the Insulating Structures of A Flight Data Recorder
Authors: Panas Andrzej J. , Szczepaniak Robert , Krupińska Anna , Łęczycki Krzysztof , Nowakowski Mirosław
Published: July 2024

This paper deals with the problems faced during the research on the insulating structures used in the thermal shielding of flight recorders. These structures are characterised by specific properties determined by, among other aspects, their porosity. The complex and coupled heat-exchange phenomena occurring under the operating conditions of the recorders, and in numerous cases combined with mass exchange, require dedicated test methods. The paper characterises the origin of the research problem, presents a methodology for comprehensive testing of the thermal propertiesand uses the example of determining the insulating properties of the Promalight microporous structure ®-1000R. The authors focussed on thermal diffusivity tests performed by means of the oscillatory excitation method. The measurements were conducted on a test stand to determine the effect the type of gas filling had on the porous structure and the pore filling gaspressure effect on the temperature characteristics of apparent thermal diffusivity. The authors also conducted research on the structure’s resistance to direct flame exposure. The analysis of the obtained results enable recognition and characterisation of the key phenomena of heat and mass transfer; the numerical results exert a significant influence on their application.
Limits of Commitments
Authors: Dominik Martin
Published: July 2024

In this paper, I examine Brandom’s notion of a de re reading of a tradition and question its legitimacy under certain circumstances. Specifically, I argue that within the language game of giving and asking for reasons, commitments should be ascribed to the utterer within reasonable limits, with the utterer only responsible for intentional or negligent breaches of duty. Even if we were to include an ideal speaker who knows all facts available at the time of her utterance, she cannot be held accountable for ignorance of things that do not yet exist. Therefore, I further argue that the time of the utterance must be taken into consideration when ascribing commitments and keeping score in the game of giving and asking for reasons. This temporal aspect is suppressed by Brandom’s notion of de re reading for pragmatic reasons, as he seeks to tell an inferentialist story of the philosophical tradition. Nevertheless, I argue that legitimacy poses a problem even for this approach because Brandom formulates his account in terms of rules, responsibility and sanctions. I offer a critical perspective on Brandom’s de re reading and the broader implications of his inferentialist framework.
Numerical Simulation of Air Distribution in a Wide Chute
Authors: Shayanseresht Saeed
Published: July 2024

Desirable conditions of airflow should be provided for spillway chute aerators in two-phase air-water flow, especially in large-width chutes. There is no general approach to determine air entrainment, concentration distribution, and submergence along a chute introduced by an aerator shaft. The two-phase air-water modeling of Gavoshan dam in Iran as a case study of chute flow, its aerator, and the characteristics of flow into the cavity formed below the jet have been numerically investigated, and the results obtained have been validated against the laboratory experiments. The hydraulic parameters of the cavity and aerator shaft were determined to evaluate their performance and emphasize the importance of a proper aerator design. Sections with a greater distance from the bottom of the chute exhibit higher pressure magnitudes, while the mean air concentration values in the cavity are smaller in sections close to a ramp. Higher water discharge, lower pressure head in sections near the bottom of the cavity, and lower air concentration in sections near the ramp into the cavity increase the probability of cavitation occurrence.
Recombinase Polymerase Amplification assay for detection of the British root-knot nematode, Meloidogyne artiellia
Authors: Subbotin Sergei A. , Palomares-Rius Juan E. , Castillo Pablo
Published: July 2024

Recombinase polymerase amplification (RPA) is an isothermal in vitro nucleic acid amplification technique that has been adopted for simple, robust, rapid, reliable diagnostics of nematodes. In this study, the real-time RPA assay and RPA assay combined with lateral flow dipsticks (LF-RPA) have been developed targeting the ITS rRNA gene of the British root-knot nematode, Meloidogyne artiellia. The assay provided specific and rapid detection of this root-knot nematode species from crude nematode extracts without a DNA extraction step with a sensitivity of 0.125 second-stage juvenile (J2) specimen per a reaction tube for real-time RPA during 11 min and a sensitivity of 0.5 J2 specimens per a reaction tube for LF-RPA during 25 min. The RPA assays were validated with a wide range of non-target root-knot nematodes. The LF-RPA assay has great potential for nematode diagnostics in the laboratory having minimal available equipment.
How a Child Learns to ‘Talk’ to a Smart Speaker: On the Emergence of Enlanguaged Practices
Authors: Fester-Seeger Marie-Theres
Published: July 2024

In this paper, I am concerned with the socio-material practice of engaging with voice-enabled machines. Far from ‘talking’ to a smart speaker, a user must master the skill of composing a command while routinely engaging with the machine. While the practice relies on practical understanding and intelligibility, attention must be paid to the trans-situational aspects that enable the situated enactment of socio-material practices. By conceptualizing engagement with the smart speaker as an enlanguaged practice, I trace the ability to engage in a seemingly individualistic practice to a person‘s history of engagement in and with the world. Specifically, I consider how a pre-literate child relies on instances of recursive bodily coordination with her caregiver to learn how to engage with a smart speaker. Informed by the languaging perspective which treats language as multiscalar bodily verbal activity, I trace enlanguaging to the intricate interplay of dialogicality, temporality, and embodiment.
Frost-salt Testing Non-air Entrained High-Performance Fly-ash Concrete. Part I: Relations Liquid uptake - Internal Cracking – Scaling
Authors: Asadi Iman , Skjølsvold Ola , Kanstad Terje , Jacobsen Stefan
Published: July 2024

The surface scaling of low CO2-emission High Performance Concretes (HPC) was studied in freeze/thaw performance tests with a 3 mm layer of 3% NaCl on the surface to investigate whether such concretes can be made frost durable without air entrainment. Four different non-air entrained silica fume (SF)-fly ash concrete mixes with w/b = 0.30 – 0.35 with 91d strengths >100 MPa were investigated after 3 different curing conditions (Normal, Dried, Wrapped). The w/b=0.30 CEM IIA reference mix without additional FA had lowest scaling following all curing conditions. However, all 4 mixes at all 3 curing conditions had severe internal damage. Liquid Uptake (LU) during freeze/thaw related best to internal damage. The correlation between LU-scaling and strain-scaling was very good for wrapped curing which also showed high internal damage. We therefore suggest proceeding in modelling simultaneous salt scaling and internal damage.
The Social Practice of E-Sports in the United Arab Emirates: An Empirical Field Study on a Sample of University Students
Authors: Benlarbi Yahia , Hashim Samia , Belghitia Samira
Published: July 2024

This research examines United Arab Emirates (UAE) university students’ electronic sports habits and motivations using the theory of uses and rewards and the motivation scale for sports consumption (MSSC). A deliberate sample of 172 participants was surveyed using an electronic questionnaire to give their perspectives on various electronic sports-related topics. Most respondents considered e-sports a serious sport and valued it as a social practice. They practiced e-sports for two to four hours daily, preferring multiplayer games, confirming the collective tendency. Live-streaming services have helped electronic sports to become mainstream. Considering the UAE’s enthusiasm, most respondents played e-sports professionally. Finally, indirect realization, aesthetics, and escapism motivated e-sports players. These findings shed light on the perspectives and experiences of UAE residents who participate in electronic sports and may be used to guide efforts to legitimize and mainstream the activity.
Endoscopic Colour Analysis of Nasal Mucosa: Methodology and Clinical Data
Authors: Rubīns Uldis , Krieviņa Agate Kristena , Peksis Kaspars , Spīgulis Jānis
Published: July 2024

Diseases of the nasal mucosa are common in clinical practice; on average, every third ENT (ear, nose, throat) patient complains of nasal mucosa problems. Mucosa pathologies change the structure and composition of tissue; the presence of different cells, variation in biochemical composition and dilation or constriction of blood vessels lead to mucosa colour changes that help setting the diagnosis. However, experience and colour vision vary between doctors, so a more objective mucosa colour examination could be helpful. The aim of this study was to investigate whether colour analysis of camera-captured endoscopic images can distinguish healthy from pathological nasal mucosa and how specific such analysis could be for various diseases. A total of 66 participants (four groups, including healthy volunteers) underwent anterior nasal endoscopy, and the taken photos and videos were further analysed using self-developed Matlab software. The procedure involved selection of the region of interest (inferior nasal turbinate), segmentation and averaging the colour parameters over selected areas, exploiting the RGB and L*a*b colour scales. Allergic, chronic hyperplastic and inflamed (chronic and acute) nasal mucosa conditions in comparison with healthy mucosa were studied in this work. A relatively wide spread of colour parameter values was observed in the healthy volunteer group as well as in all patient groups. The most sensitive colour parameters for each of the pathology groups were identified.
How Changes in Plant Taxonomy Are Reflected in Practice, the Case of Salix alba, S. euxina and S. × fragilis Complex: An Example of Latvia’s Official Normative Documents
Authors: Stalažs Arturs
Published: July 2024

In 2009, the nomenclature of the former ‘Salix fragilis’ complex was revised; as a result, the pure species Salix euxina Belayeva was described. Over the past ten years, these changes have been ignored by a number of authors (both in Latvia and abroad), and only some authors have used all the names within this complex according to nomenclatural changes introduced by Belayeva. In the context of these taxonomic changes, the official Latvian normative documents (regulations) were analysed in regard to the species Salix alba, S. euxina and S. ×fragilis (=Salix ×rubens).Unfortunately, the taxon S. euxina is not recognised at the official level in Latvia, but the name ‘S. fragilis’ is widely used, referring more to the S. euxina; and S. ×rubens for the S. alba/euxina hybrid complex. Given that plant taxonomy is studied by experienced scientists rather than political organisations, in theory, politicians who lay down national laws and regulations as well as scientists should follow reasoned and justified changes in plant taxonomy. In case of the former S. fragilis complex, these taxonomic changes are also confirmed by genetic studies, which gives an even greater justification for their validity. Therefore, there is no reason to ignore these taxonomic changes.
Forced Fiscal Regulation: Impact Factors and Efficiency
Authors: Butmalai Valentina , Săracu Alina-Florentina , Susanu Irina , Abedin Bahareh
Published: July 2024

Tax regulation issues have been the focus since the COVID-19 crisis and the subsequent EU energy crisis. From the Keynesian approach, the expansionary fiscal policy of states can contribute to stimulating aggregate demand and, as a consequence, economic growth, on the other hand, the post-crisis macroeconomic policy trend has become fiscal compression (budget consolidation), corresponding to the neoliberal paradigm. This policy has been actively promoted by the supranational institutions of EU, which, with the help of various instruments of fiscal regulation, have effectively imposed budgetary consolidation on member countries.

Considering that the European Commission continues to urge countries to better the sustainability of their public finances and believes that the situation with the tax system is only safe in some EU countries, while in others, it finds significant imbalances, exceptionally high levels of public debt, which need to be corrected by the Stability and Growth Pact mechanisms, the relevance of this study is beyond doubt.

Authors: Mihai Vasile Iuliana , Hrestic Maria-Luiza , Nicolae Stan Ana-Maria
Published: July 2024

Analyzed from a social, educational and psychological point of view, the phenomenon of bullying has become a global concern in all schools. Taking into account the harmful effects they have on all educational factors (children, parents and teachers), governments around the world to create some policies and dedicated to the prevention and reduction of bullying in the school environment. In recent years, there has been an increasing number of acts of violence and intimidation, both in schools and in the online environment, becoming a problem not only in high schools in Romania, but also in secondary and even primary schools. Thus, although the statistics are worrying, legislative changes in the field of bullying in the educational system in Romania are at the beginning of the road and aspects are generally aimed at prevention. The present paper proposes to bring to the fore the need to develop an integrated intervention strategy in cases of school bullying, by involving the decision-making factors.

Published: July 2024

In order to improve the adsorption performance of CaO prepared from duck egg shells, a 1:1 composite of CaO/Fe3O4 were synthesized using a coprecipitation method. This composite was then used to adsorb Congo red and Procyon red MX-5b dyes from an aqueous solution. The adsorption process was studied by investigating the effects of contact time, temperature, and initial concentration of dye. It was found that the optimum conditions for Congo red adsorption are 50 minutes of contact, 50 °C, and 225 mg/L of dye, while for Procyon red MX-5b the conditions are 50 minutes of contact, 60 °C, and 250 mg/L of dye. The behavior of both adsorbents at equilibria follows a pseudo-second-order kinetic model and Langmuir isotherm, with the adsorption capacity at optimum condition for Congo red and Procyon red MX5b 46.95 mg/g and 47.39 mg/g, respectively. Thermodynamics studies showed that the adsorption process of Congo red was endothermic, while Procyon red MX-5b was exothermic, yet both were found to happen spontaneously.

Published: July 2024

A color scanner application using the TCS3200 sensor, Arduino Uno microcomputer with IDE Software Program, a black box container, and a 12x2 matrix display has been designed, built, and tested. This sensor is employed to measure the level of borax in food items such as meatballs, tofu, and noodles in Banda Aceh. The obtained results are then compared with the measurement results of the Standard Ultraviolet-Visible Spectrophotometry (UV-Vis) method. Samples were prepared using centrifuge technique and the filtrate was collected. Subsequently, optical samples were prepared using dried filter paper with curcumin and scanned with the TCS3200 color sensor. Sample collection was carried out at Lamnyong Market, Lamdingin Market, Seutui Market, Suzuya Mall, and Ulee Kareng Market. Sample identification was performed using qualitative analysis, namely the flame test, and quantitative analysis using the TCS3200 color sensor based on Arduino Uno. The results of the quantitative analysis obtained from the TCS3200 color sensor compared with the ultraviolet-visible spectrophotometry (UV-Vis) method as the standard method indicate that the samples of meatballs, tofu, and noodles do not contain the harmful preservative borax. The positive control for borax using the TCS3200 color sensor is 56.8 ppm, while using the UV-Vis spectrophotometer it is 57.6 ppm. The t-test results from both methods show consistency between the TCS3200 color sensor measurement method and UV-Vis spectrophotometer
Sustainability and Sustainable Public Procurement: An Assessment of Individual, Organizational, and Political Commitment in Brazilian Public Administration
Authors: Inglat Luís Phillipe da Silva , Cabral Vitor Neves , Castro Biancca Scarpeline de , Guerrieri Daduí Cordeiro
Published: July 2024

Objective: To analyze the commitment to sustainability and sustainable public procurement by individuals, organizations, and the political class, based on the perceptions of agents working in the procurement area.
 
Theoretical Framework: The main concepts and theories on sustainability and sustainable public procurement (SPP) were presented, as well as the importance of commitment from individuals, public organizations, and the political class for the implementation of these agendas.
 
Method: A quantitative approach was adopted, using a survey via an electronic questionnaire composed of closed questions with alternatives based on a five-point Likert scale. The sample consisted of 201 public agents working in the procurement area, and statistical analysis of the data was conducted to identify patterns and relationships between the variables regarding the perceptions of public agents.
 
Results and Discussion: Commitment to sustainability and SPP ranged from moderate to low, with the level of political commitment being lower than organizational commitment, and the latter being lower than individual commitment. At all levels (individual, organizational, and political), the commitment to CPS was lower than the commitment to sustainability. In line with the literature, the individual, organizational, and political commitments perceived in this research may explain the modest progress of these themes in recent years, despite their inclusion in the Brazilian legal framework and the existence of successful practices.
 
Research Implications: This study points to the need to promote initiatives that can enhance commitment to sustainability and SPP by the agents responsible for implementation, as well as by public organizations and the political class.
 
Originality/Value: This study contributes to the literature by addressing commitment to sustainability and SPP in the Brazilian context at different levels - individual, organizational, and political. By identifying patterns and relationships between variables, the research provides important directions for understanding opportunities and challenges associated with promoting sustainability and SPP.

Non-Linear Models With Autoregressive Error Structure for Studying Bean Seed Drying Kinetics
Authors: Gonzaga Natiele de Almeida , Azarias Edilene Cristina Pedroso , Salvador Rafaela de Carvalho , Silva Edilson Marcelino , Muniz Joel Augusto
Published: July 2024

Objective: To use the non-linear regression models (Lewis, Overhults, Page, Midilli, and Three-parameter simple Exponential) to describe the drying kinetics of bean seeds as a function of time (hours).
 
Theoretical Structure: The research project shows the steps taken to conduct and analyze data.
 
Method: The model parameters were estimated using the least squares method and the Gauss-Newton convergence algorithm. The assumptions of normality, homoscedasticity, and independence of residuals were tested using the Shapiro-Wilk, Breuch-Pagan, and Durbin-Watson tests, respectively. If the assumption of independence of residuals was violated, this dependence was modeled with an autoregressive error structure AR(1). The adjusted coefficient of determination (Raj2), Akaike information criterion (AIC), residual standard deviation (RSD), and Bates and Watts curvature measure were used to assess the goodness of fit of the models.
 
Results and conclusion: The results showed that the Midilli model presented a good quality fit to the data, and is the most suitable for describing the drying kinetics of bean seeds, with the drying rate averaging 0.4681 g of water/hour.
 
Research Implications: The research contributes to the literature with practical information about the drying process.
 
Originality/value: Highlights the importance of adjusting non-linear regression models to the drying kinetics of biological products. These models are used to represent the decrease in the amount of water in a given food over time.

Lo sagrado en Alcohólicos Anónimos: el dios de los alcohólicos
Authors: Torres Fabián
Published: July 2024

Este artículo examina la visión de lo sagrado presente en el programa de recuperación de Alcohólicos Anónimos mediante el análisis de su bibliografía y con ayuda de la Religioswissenschaft. Se hace un breve recorrido histórico de la agrupación con el fin de mostrar los postulados religiosos que dieron origen a esa visión y se concluye que, independientemente de si Alcohólicos Anónimos es o no una agrupación religiosa ─este artículo no participa en ese debate─, su visión teológica remite a un dios específico y no solo a un poder superior abstracto, como asegura la organización.
Palabras clave: Alcohólicos Anónimos, espiritualidad, lo sagrado.
La calidad ambiental urbana a través de la perspectiva ciudadana
Authors: Velázquez Álvarez Oscar Uriel
Published: July 2024

Son pocos los trabajos que abordan el estudio de la calidad ambiental urbana desde la óptica ciudadana, sin embargo, durante los últimos años países como Venezuela, Colombia y España han empleado técnicas de valoración de la calidad ambiental desde la perspectiva ciudadana, introduciendo herramientas y métodos propositivos para la planeación urbana y calidad de vida, en las cuales, los resultados han demostrado la importancia de considerar al habitante como principal referente de la calidad ambiental en las ciudades debido a que abre paso a la formulación de acciones de intervención en función de las necesidades de los mismos, lo que garantiza su satisfacción y mejora el nivel de calidad de vida urbana. Por lo tanto, la introducción del concepto de calidad ambiental urbana desde la perspectiva ciudadana en la gestión y planeación urbana de México, país que presenta un importante rezago en estudios de esta índole, resulta imprescindible para mejorar la calidad ambiental urbana y por ende la vida de sus habitantes.

Published: July 2024

La vivienda y la habitabilidad están íntimamente relacionadas y son fundamentales para el bienestar humano. Garantizar condiciones adecuadas en la vivienda es esencial para promover la salud, la seguridad y la dignidad de las personas. Según el informe de las Naciones Unidas sobre el derecho a una vivienda adecuada, "la vivienda es central para el bienestar individual y colectivo, y tiene un impacto significativo en la salud física, mental y emocional, la seguridad, la igualdad y la dignidad humana" (ONU-Hábitat., 2020). En este artículo se pretende realizar un análisis y evaluación de las condiciones de habitabilidad de las viviendas destinadas para los jornaleros agrícolas radicados en el Sur de Jalisco, México y sus implicaciones en la calidad de vida. El enfoque metodológico es de corte cualitativo y se complementa con información estadística. La metodología del estudio se dividió en tres partes. Como primer paso se realizó un análisis y clasificación de los tipos de viviendas para trabajadores de la agroindustria en los municipios de la región. En segundo lugar, se seleccionaron dos modelos de vivienda como casos de estudio, donde se recogieron datos relevantes sobre las viviendas y su entorno a partir del método etnográfico mediante evidencia gráfica, fotográfica y aplicación de cuestionarios de evaluación. Finalmente, se analizaron los resultados obtenidos confrontando las diferencias espaciales de ambos casos y su inferencia en el bienestar y calidad de vida de sus ocupantes.
Territorio, vivienda y reconfiguración. Tenencias del sureste de Morelia, Michoacán
Authors: Aguilar Hernández Elsa Anaid
Published: July 2024

El presente trabajo expone la dicotomía inmersa en las relaciones campo ciudad, suscitadas por el proceso de conurbación. Aquí se anuncian aspectos relacionados con el valor cultural, formas de vida y los cambios derivados del crecimiento exponencial de la mancha urbana en el territorio de borde, que tiene como fin el ofrecer vivienda de baja densidad y que conlleva a su paso modificaciones diversas en el habitar de los pobladores preexistentes. Así mismo, se hace un breve estudio relativo a algunas modificaciones realizadas al artículo 27 constitucional, que facilitaron el cambio de uso de suelo de rural a urbano. Es pertinente mencionar que el proceso de reconfiguración territorial de los bordes urbanos es una constante en nuestro país tanto en áreas boscosas, como en sitios de playa, lo que hace relevante el tema, y en este caso es abordado bajo el análisis y la exploración de hechos que modifican tanto el habitar del ser humano, como el medio físico natural. El objetivo de este estudio es el de identificar la relación existente entre producción del espacio físico, el sustento y las prácticas cotidianas de borde urbano, en el medio rural y la ciudad. La metodología surge desde la geografía regional, mediante el análisis del espacio físico y el habitar. Al respecto nos cuestionamos ¿en qué elementos se puede evidenciar la reconfiguración del territorio y cuál es su impronta en el medio físico y natural?

Leber Hereditary Optic Neuropathy: Report of Two Cases and Clinical Overview
Authors: Duc Anh Nguyen , Thanh Tung Hoang , Thi Hong Nhung Le
Published: July 2024

Introduction: Leber hereditary optic neuropathy (LHON) is a rare genetic condition characterized by bilateral irreversible vision loss, predominantly affecting young males. Case presentation: We report two clinical cases of two young male patients who were admitted to the hospital because of painless vision loss. Their family members either have the LHON condition or carry a mutation of that in their gene. Fundoscopic examination of the optic nerve currently appeared to have temporal pallor. Orbital Magnetic Resonance Imaging (MRI) scan showed hyperintensity of the optic nerve. Optical Coherence Tomography (OCT) of the optic nerve head and retinal nerve fiber layer showed thinning of the temporal nerve fiber layer. Humphrey visual field revealed paracentral scotoma. Genetic testing revealed the patients had a m.11778G > A mutation in MT-ND4 gene. They were both treated with oral Coenzyme Q10 and Idebenone. Conclusions: Leber's hereditary optic neuropathy may mimic optic neuritis in the acute phase, requiring precise, systematic clinical evaluation and genetic testing for confirmation.
الأوراسية الجديدة وممكنات الصعود الروسي نحو العالمية في ظل أفكار الكسندر دوغين : دراسة جيو سياسية نقدية

لقد شكل انهيار المنظومة الشيوعية بقيادة الاتحاد السوفيتي السابق ، علامة فارقة ونقطة تحول كبيرة في مجرى العلاقات الدولية ، والتي كانت من أهم نتائجها ظهور الولايات المتحدة الامريكية كقطب اوحد ومهيمن على الشأن الدولي ، فضلا عن الانعكاسات الكبيرة على الداخل الروسي وعلى مختلف المستويات ، إذ افرز هذا التحول في المشهد العالمي ، ظهور العديد من المفكرين والسياسيين الروس الذين اخذو بالتفكير بإعادة أمجاد دولة روسيا كونها تمتلك ما يؤهلها من مقومات القوة لتكون قطبا موازيا للولايات المتحدة الامريكية ، فضلا عن امتلاكها الايديولوجية السياسية والتي باستطاعتها في حال اغتنام الفرصة من توظيفها بالشكل الذي يخدم مصالحها واهدافها للوصول الى العالمية ، علما بأن هذه الايديولوجية تتميز بكونها شاملة لجميع دول العالم ، وعلى الرغم من ظهور عدة شخصيات استراتيجية وسياسية اهتمت بالشأن الروسي ، إلا اننا ومن خلال هذه البحث سوف نركز على شخصية واحدة ، أخذت تبرز وبشكل لافت في المشهد السياسي الروسي ، والسبب يعود في ذلك الى كثرة طروحاته الفكرية التي لاقت رواجا لها داخل المجتمع الروسي وخارجه ،بحيث وصف بأنه " عقل بوتين " و " ظاهرة دوغين " و " الفاشي الجديد " و " اليميني المتطرف " إذ جاء هذا البحث ليسلط الضوء على ابرز افكار دوغين من خلال تناوله للاوراسية الجديدة ، وهل من الممكن وعبر تلك الافكار أن تصل روسيا الى العالمية في ظل ما تمتلكه من مقومات سياسية واقتصادية وعسكرية ، ومن بين تلك الآراء والافكار الجيو سياسية الجديدة. بأن الاوراسية التي تحتل روسيا فيها مكانة القلب تتكامل مع النظرية السياسية الرابعة وتشكل الايديولوجية الرسمية التي يجب أن تتبناها روسيا كمشروع سياسي عالمي تجعل من روسيا دولة قوية قادرة على تحقيق أهدافها العالمية، وتنهي تفرد الولايات المتحدة الامريكية كقطب أحادي مسيطر على النظام الدولي .

الأمن القومي العراقي: دراسة في أثر المتغير الإقليمي
Authors: راضي د. محمد عبدالله
Published: July 2024

تلقي التطورات المتسارعة في العالم بظلالها على تفاعلات العراق مع جواره الاقليمي، كما تنعكس الطبيعة الداخلية للأنظمة السياسية والاوضاع المجتمعية في تحييد، او تبدل، او ظهور متغيرات اقليمية جديدة مؤثرة في الامن القومي العراقي. ومن ذلك، وجد ان تفاعل تلك التطورات مع الاولويات الوطنية تفضي الى وجوب التكيف مع القواعد الاقليمية الجديدة سواء أكانت بشكل تهديدات او فرص. وهو ما تم افتراضه في هذا البحث والتحقق منه من خلال استخدام مناهج متعددة من بينها المنهج التحليلي. وقد ثبُت الى ان العراق بحاجة الى استراتيجية وطنية شاملة تكون ساندة ومكملة للخطط المجتمعية والبرامج الحكومية والتنمية الاقتصادية، هذه الاستراتيجية الوطنية تكون ميسرة ومكملة لرؤية العراق في السنوات القادمة. وبالمحصلة، فأن واحدة من اهم العوامل التي تعمل على تحييد عناصر التهديد الخارجي للأمن القومي العراقي، تكمن في بناء المواطنة العراقية المتفق عليها داخلياً والتي تعزز من روح الانتماء.
