La Relación de los Actores Colectivos con el Estado: el Caso Venezolano
Authors: Valdez-Sarabia Magaly
Published: January 2025

La relación entre el Estado y la sociedad en Venezuela ha experimentado importantes transformaciones desde el ascenso del chavismo hasta la era postchavista. Este artículo analiza las interacciones entre actores colectivos y el proyecto hegemónico estatal a lo largo de tres periodos: 1999-2006, 2006-2015 y 2015-2022. Se exploran los cambios desde la incorporación de demandas populares y la promoción de mecanismos participativos, hasta el debilitamiento de los vínculos con sectores organizados debido a la crisis del modelo de desarrollo. Aunque el bloque de poder ha perdido legitimidad y se enfrenta a limitaciones estructurales, algunas organizaciones han desarrollado estrategias efectivas para mantener su capacidad de acción e influencia en el Estado por medio de tres vías: autonomista, itinerante y estratégica. Comprender estas dinámicas requiere una perspectiva relacional que considere tanto los aspectos formales como los mecanismos informales y las bases sociales que configuran el campo socioestatal venezolano.
Una mirada a los sistemas alimentarios de Colombia para pensar las políticas públicas alimentarias y nutricionales
Authors: Ruiz Pineda Adriana Marcela , Cadavid Castro Martha Alicia
Published: January 2025

Se realizó una revisión narrativa de literatura de los años 2003 a 2023, para describir la situación actual de algunos elementos de los sistemas alimentarios en Colombia. Se encontró que en este país predomina la producción agrícola basada en monocultivos con uso intensivo de plaguicidas y fertilizantes químicos y la ganadería extensiva en latifundios, el área ocupada por pequeños productores es reducida. El aporte del sector agropecuario al producto interno bruto es bajo y se depende de importaciones de alimentos para el abastecimiento. Más de la mitad de la población tiene dificultades para acceder a los alimentos, lo que puede explicar la prevalencia de malnutrición y enfermedades no transmisibles en la población. Se requieren políticas de producción agropecuaria saludable y sustentable, y medidas dirigidas a mejorar los entornos alimentarios para mejorar la salud de las personas y mantener la biodiversidad.

Published: January 2025

Background: The association of fragmented QRS (fQRS) with many cardiac pathologies such as cardiac fibrosis has been described previously. Paraaortic adipose tissue (PAT) is thought to be associated with many cardiac diseases and there is only one publication on its echocardiographic evaluation. This study aims to describe the possible relationship between fQRS and PAT.
Methods: Patients presenting to the cardiology outpatient clinic were evaluated for inclusion in the study. Presence of additional R' wave or notching/splitting of S wave in two contiguous ECG leads was defined as fragmented QRS (fQRS) and patients were divided into two groups according to fQRS status on ECG. The hypoechoic space in front of the ascending aorta was considered as PAT in the parasternal long-axis view. The medical history and routine laboratory parameters of the participants were recorded. Univariate and multivariate binary regression analysis was used to determine the relationship between PAT and fQRS.
Results:A total of 221 patients were enrolled and divided into two groups according to fQRS status. PAT was significantly higher in the fQRS group [9.2mm (7.1/12.3) vs 6.8mm (1.2/10.9), p=0.001]. Univariate analysis showed significant association between fragmented QRS and PAT size (OR 1.122, p= 0.001).  Binary regression analysis revealed an independent and strong association between aortic size (OR 1.4, CI 1.012-1.938, p=0.042), paraaortic adipose tissue (OR 1.483, CI 1.084-2.029, p=0.014) and fragmented QRS.
Conclusions: The presence of fQRS is associated with PAT, a newly defined parameter in echocardiography.

Published: January 2025

Objectives:

This study was conducted to assess clinico-epidemiological features of atopic dermatitis (AD) in children and evaluate disease severity using the SCORing atopic dermatitis index (SCORAD Index).

Material and Methods:

This was a hospital-based cross-sectional study carried out at the department of Dermatology at a tertiary care centre in North India over a period of 1 year. This study enrolled children aged between 3 months and 16 years of age clinically diagnosed with AD using Hanifin and Rajka criteria (HRC).

Results:

The prevalence of AD was found to be 8.12%. Age of presentation ranged from 4 months to 16 years of age, with a mean age of 4.18 ± 3.88 years. 42% of patients had personal and 52.50% of patients had a family history of atopy. We report pruritus as a major presenting symptom seen in 100% of children with AD. Typical morphology and distribution were observed in 97.50% of cases, with the face being the most commonly affected site in infants (95.08%) and flexural involvement more common in children (77.70%). Infants had acute eczema (63.93%) and children with AD mostly presented with chronic eczematous lesions (58.27%). The most common minor feature of HRC observed was xerosis, seen in 94% of patients. Amongst atypical features, scalp scaling was the most common feature seen in 17%. SCORAD Index grading was mild in 49.50% of children with AD, moderate in 40.50% and severe grading was seen only in 10% of children.

Conclusion:

Clinical features, prevalence and severity of AD are affected by various geographical, environmental and local factors such as lifestyle, clothing and eating/dietary factors.

Zachowania transgresyjne w rozwoju zawodowym osób z zaburzeniami integracji sensorycznej
Authors: Kozakiewicz Jerzy
Published: January 2025

Przełamywanie barier, pokonywanie własnych ograniczeń jest udziałem każdego z nas. Nie każdy zdaje sobie jednak sprawę, że są wśród nas ludzie, którym – choć są w zasadzie zdrowi – pokonywanie owych barier przychodzi ze szczególnym trudem. Nazywani są różnie: fajtłapami, ciapami czy dźwięcznie – po angielsku – clumsy. Nie są chorzy, tylko ich mózgi (z powodów opisanych poniżej) działają nieznacznie inaczej. Potykają się bez powodu, ciągle im coś wypada z rąk, źle reagują na określone dźwięki, smaki, zapachy. Czasem przez to krzyczą i uciekają, wzbudzając niezdrową ciekawość gawiedzi. Muszą oni przez to mierzyć się z niezrozumieniem, ostracyzmem społecznym, czasem z brakiem akceptacji nawet wśród najbliższych. Szkoła, a później praca zawodowa stają się przez to dla nich wyjątkowo trudnym wyzwaniem. Są to osoby z zaburzeniami integracji sensorycznej, a niniejszy artykuł jest próbą zbadania i przedstawienia, w jaki sposób radzą sobie oni w środowisku szkolnym i w trakcie kariery zawodowej.

Abstract Trademark rights as movable and intangible objects because they can be bought or sold and have economical value should have the opportunity to be used as collateral objects. In accordance with the principle of specialization, guaranteed trademark rights must be proven by a trademark certificate as a sign that the trademark has been registered. However, the Trademark and Geographical Indications Law does not explicitly regulate what collateral institutions can cover trademark rights. The problem is what are the criteria and implementation of brand rights as collateral objects to obtain credit? The method used in this type of research is normative legal research. The results of the study brand rights can be used as credit collateral because they have the characteristics contained in material security rights, such as the brand is the property or personal property of the brand owner; has economic value; movable or hand-transferable; has the characteristic of droit de suite, namely following the object wherever the object is. Abstrak Hak Merek sebagai benda bergerak dan tidak berwujud karena dapat diperjualbelikan dan memiliki nilai ekonomis seharusnya mempunyai kemungkinan untuk dijadikan sebagai objek jaminan. Menurut asas spesialitas, hak merek yang dijaminkan harus dibuktikan dengan adanya sertifikat merek sebagai tanda telah didaftarkannya merek tersebut. Namun, dalam UU Merek dan Indikasi Geografis tidak diatur secara eksplisit mengenai lembaga jaminan apa yang dapat membebani hak merek. Adapun permasalahan agaimana kriteria dan pelaksanaan hak merek sebagai objek jaminan untuk mendapatkan kredit? Metode yang digunakan jenis penelitian ini adalah penelitian hukum normatif. Hasil penelitian hak merek dapat dijadikan sebagai jaminan kredit karena memiliki sifat-sifat yang terdapat dalam hak jaminan kebendaan seperti merek merupakan kepunyaan atau hak milik pribadi pemilik merek; mempunyai nilai ekonomi; dapat dipindahtangankan atau dialihkan; mengikuti bendanya dimanapun benda itu berada (sifat droit de suite).
Characterizing the conformational ensemble of PROTAC degraders in solutions via atomistic simulations
Authors: Bhusal Shikshya , Valsson Omar
Published: January 2025

Targeted protein degradation has emerged as a promising strategy for developing novel therapeutics, particularly for "undruggable" disease-related proteins. One approach is the use of PROteolysis TArgeting Chimeras (PROTACs) degraders, which induce the formation of ternary complexes between the target protein and E3 ligase, leading to ubiquitination and degradation of the target protein. Understanding the conformational behavior of PROTACs in solutions and how it relates to their pharmacokinetic properties is crucial for optimizing PROTAC design and efficacy. Due to the large size and flexibility of PROTACs and their chameleonic character, it is essential to understand their conformational ensemble, and how it depends on the environment, rather than considering a single structure. Here, we introduce a novel methodology for exploring PROTAC conformational behavior using atomistic simulations. We employ the enhanced sampling method Parallel-Bias Metadynamics, where we bias generic local collective variables, specifically all rotatable dihedral angles, thereby avoiding the considerable challenge of identifying suitable global collective variables for biasing. The methodology allows for obtaining free energy surfaces of global CVs via reweighting, thus giving valuable insight into the conformational ensemble. We apply the method to the prototypical case of the MZ1 PROTAC degrader, which targets bromodomain-containing protein-4 (BRD4) for degradation via the von Hippel-Lindau (VHL) E3 ligase, and elucidate its conformational behavior in different solvents, allowing us to gain insights into the chameleonic property of MZ1. Our methodological framework is generally applicable to large flexible molecules like PROTACs and the results demonstrate its efficiency, laying the groundwork for similar investigations for other PROTACs and other "beyond-rule-of-5" drug candidates. This work provides valuable insights into the design and optimization of PROTACs, ultimately contributing to developing novel therapeutics for "undruggable" diseases.
Overbreadth Revisited
Authors: Stewart Hamish
Published: January 2025

The norm against overbreadth—a law should not be overbroad in relation to its own purposes—is well established as a principle of fundamental justice under section 7 of the Charter. But the Supreme Court of Canada’s case law contains two competing formulations of this norm. According to the strict version of the norm, a law is overbroad if it applies in even one (actual or hypothetical) case that is not directly necessary to the achievement of its purpose. According to the relaxed version of the norm, a law is overbroad only if it applies in cases beyond those that are reasonably neces-sary to its operation. The strict version of the norm is unworkable because it relies on two un-tenable assumptions: first, that a law is always an instrument for achieving a purpose that can be fully specified apart from the idea of legal order; second, that a law can be drafted and applied so that it never goes beyond that pur-pose. The result is that, on a proper application of the strict version of the norm, all laws are overbroad. The relaxed version of the norm shares the first assumption but not the second. With respect to those laws that are properly characterized as instrumental, it would be bet-ter to abandon the strict version of the norm and adopt the relaxed version
autorité internationale des fonds marins :
Authors: Kempf Nicolas
Published: January 2025

La Zone internationale des fonds marins (la « Zone ») est administrée par l’Autorité in-ternationale des fonds marins (l’« Autorité ») au nom et au bénéfice de l’humanité tout entière. Bien que l’Autorité se soit d’abord concentrée sur l’élaboration de règles relatives à l’exploration et à l’exploitation de la Zone, elle dispose également d’un mandat environnemen-tal. Dans cette contribution, l’auteur se penche sur les fondements de la protection de l’environnement des fonds marins internatio-naux, depuis la conceptualisation du patri-moine commun de l’humanité jusqu’à la modifi-cation de ce concept dans l’Accord relatif à l’application de la partie XI de la Convention des Nations Unies sur le droit de la mer de 1994. Il procède ensuite à l’analyse de l’évolution ré-cente du mandat environnemental de l’Autorité dans le but de dénoncer l’écart entre le discours de plus en plus environnementaliste de cette ins-titution et le peu de mesures concrètes adoptées.
Changes in Attitudes Toward the Enemy in Modern Wars: Dehumanization of Russian Soldiers in the Perception of Civilians and the Military of Ukraine
Authors: Skorokhod Kateryna
Published: January 2025

The article analyzes the possibilities and limitations of the classical sociological discourse of war for analyzing Russian aggression against Ukraine. It is emphasized that Russia's full-scale invasion of Ukraine on February 24, 2022, has created new challenges for the theoretical substantiation of sociological studies of war. The questions are raised whether it is worthwhile to fully rely on the achievements of the "new wars" theorists who argue that due to significant changes in the conduct of modern wars, Clausewitz's postulate of the secondary "paradoxical trinity" inherent in war: people, army and government cannot be applied; or whether the arguments of the supporters of the "old wars" theory should be accepted, who note that the fundamental characteristics of war remain unchanged, only the context of war becomes different. The author emphasizes the dehumanization of Russian soldiers by Ukrainian civilians and the military. Based on the analysis of the results of the author's empirical research conducted in March-June 2022 using the method of in-depth semi-structured interviews with Ukrainian civilians, as well as with military personnel and combat veterans, it is concluded that at the stage of the full-scale Russian-Ukrainian war, the attitude of Ukrainians towards Russian soldiers, in particular their dehumanization, has reached an extremely high level. The author emphasizes the differences in the dehumanization of civilians and military personnel by the enemy. It is noted that for civilians, the dehumanization of the enemy simultaneously serves to strengthen the self-identification of their own group as a conductor of humanistic values. The dehumanization of the enemy by the military is characterized by the depersonalization of Russian soldiers, and their destruction is perceived as part of their professional work. The military mostly avoids the moral context in perceiving the enemy. In both groups, both a normative aversion to violence and tolerance of aggression as a response to the enemy based on the desire to destroy it are recorded. The general conclusion is made that classical theoretical constructs on the peculiarities of interaction in intergroup conflicts, in particular in war, can be applied to explain the attitude to the enemy in the case study, which gives grounds to consider "old" and "new" wars as similar, at least in the context of the population's understanding of the events of the war. Possible further directions for theoretical and empirical research on the issues chosen by the author are identified.

Authors: Mirchuk Iryna , Zelena Oksana
Published: January 2025

This article presents the results of two waves of the sociological research "Students and War" conducted at Drohobych State Pedagogical University of Ivan Franko on June 20-27, 2022 and September 12-21, 2022. Based on the obtained data, the dynamics of psycho-emotional states of student youth were studied, a comparison of attitudes regarding the prospects of their future and the future of Ukraine after the victory in the war was made, the issue of social activity of student youth in war conditions was studied, in particular, their involvement in volunteer activities. It is shown that military topics have not lost their relevance in the youth environment even after seven months of the full-scale Russian-Ukrainian war. The predominant use of Ukrainian information resources by students has been demonstrated. It is emphasized that the war significantly affects the psycho-emotional state of youth. The level of accumulation of negative emotions related to the war, and at the same time the growth of optimistic moods of student youth, their confidence in the victory of Ukraine, and the reduction of anxiety, pessimism, hopelessness and confusion were determined. The increasing number of those, who was directly affected by the war in seven months of the war has been confirmed. Despite the duration of the war, it is emphasized that the level of faith of our students in victory only increased. It was found that for more than six months of the war, the level of social activity of young Ukrainians increased significantly primarily due to their involvement in volunteer initiatives. It is shown that with the duration of the war, the attitude of student youth towards the prospects of their own future has somewhat increased in doubt and confusion. Instead, the results of the study showed a noticeable increase in the sense of hope and optimistic feeling of the future of the Ukrainian state among the students.

Calcium as a factor in structuring the enteral flora
Authors: Ksenofontov D. A. , Ksenofontova A. A.
Published: January 2025

Experiments were carried out on animals of different species to study the parameters of calcium metabolism at the level of the small and large intestines. In monogastric and polygastric animals, the fractional composition of chyme was studied by centrifugation and the concentration of calcium in its exogenous and endogenous components was determined by atomic absorption spectrophotometry. An analysis of native chyme from different parts of the rabbit intestine was carried out by X-ray structural analysis using the small-angle diffraction method. It was found that as the chyme and its endogenous fraction move along the intestine, the calcium content increases with a predominant relative proportion of other mineral elements. Diffraction maxima exceeding the width of true crystals and characteristic of amorphous crystalline substances were obtained on X-ray patterns. The general biological phenomenon of calcium deposition in endogenous structures of chyme to form a nano-ordered framework of enteroplasm was inferred. The regularities of enteral calcium metabolism in animals of different species established during the experiments are of scientific importance for the study of the mechanisms of its homeostasis in the body and of practical value in the field of setting mineral nutritional standards, taking into account the significant calcium accumulation by endogenous components of the small and large intestines. The X-ray structural analysis of chyme complements the theoretical basis of the strip digestion concept and allows for a preliminary assessment of its physicochemical properties.
Age-related changes in fertility of female Batura toads, Bufotes baturae (Stöck, Schmid, Steinlein and Grosse, 1999), under laboratory conditions
Authors: Matushkina K. A.
Published: January 2025

The work is devoted to the study of age-related changes in reproductive parameters of female Batura toads, Bufotes baturae, under laboratory conditions. The material for the study were clutches obtained from toads aged 2 to 7 years. The highest fertility (1830±298.6 eggs) was observed in 5-year-old females. The peak of reproductive activity is between 3 and 6 years of age, after which fertility decreases statistically significantly. Other reproductive parameters (egg diameter and spawn cord width) did not show any age-related changes. The results obtained will be useful in planning laboratory and conservation projects for breeding Batura toads. Based on the results of the studies, we recommend to form a reproductive nucleus from animals aged 3-6 years.

The independent sample t-test was also used to compare two normally distributed groups, while the one-way Anova test was used to compare three or more groups. Findings reveal a positive and significant effect of HPWS on IB. Moreover, demographic factors such as gender, age, education, tenure, and status are examined for their impact on HPWS and innovation behavior, which yields varying and significant outcomes. The study contributes to theoretical understanding by identifying the mechanisms by which HPWS foster innovation and providing useful insights for organizational practitioners seeking to leverage human capital to achieve sustainable competitive advantage.

Abstract
Water used in post‐harvest handling and processing operations is an important risk factor for microbiological cross‐contamination of fruits, vegetables and herbs (FVH). Industrial data indicated that the frozen FVH sector is characterised by operational cycles between 8 and 120 h, variable product volumes and no control of the temperature of process water. Intervention strategies were limited to the use of water disinfection treatments such as peroxyacetic acid and hydrogen peroxide. Chlorine‐based disinfectants were not used, and water replenishment was not observed within studied industries. The industrial data, which included 13 scenarios, were used to develop a guidance for a water management plan (WMP) for the frozen FVH sector. A WMP aims to maintain the fit‐for‐purpose microbiological quality of the process water and consists of: (a) identification of microbial hazards and hazardous events linked to process water; (b) establishment of the relationship between microbiological and physico‐chemical parameters; (c) description of preventive measures; (d) description of intervention measures, including their validation, operational monitoring and verification; and (e) record keeping and trend analysis. A predictive model was used to simulate water management outcomes, highlighting the need for water disinfection treatments to maintain the microbiological quality of the process water and the added value of water replenishment. Relying solely on water replenishment (at realistic feasible rates) does not avoid microbial accumulation in the water. Operational monitoring of the physico‐chemical parameters ensures that the disinfection systems are operating effectively. Verification includes microbiological analysis of the process water linked to the operational monitoring outcomes of physico‐chemical parameters. Food business operators should set up and validate a tailored WMP to identify physico‐chemical parameters, as well as microbial indicators and their threshold levels as performance standards for maintaining the fit‐for‐purpose microbiological quality of the process water during post‐harvest handling and processing operations.

Abstract
This tender, developed under a self‐task mandate from the BIOHAZ Panel, analysed the characteristics of the water and the practices followed by the European food business operators (FBOs) to maintain process water quality used during the post‐harvest handling and processing operations for fresh and frozen fruits, vegetables and herbs (ffFVHs) using: information and data obtained from FBOs, experimental data extracted from literature and dynamic mass balance modelling. Quantitative data were obtained from 61 FBO scenarios (29 from the fresh‐whole sector, 19 from the fresh‐cut sector, and 13 from the frozen sector). The impact of no water treatment was evaluated in 17 scenarios, while in 44, the challenges of maintaining the microbiological quality with water disinfection agents were examined, including chlorine, peroxyacetic acid, and hydrogen peroxide. The findings highlighted that when no water disinfection treatment was used Listeria monocytogenes was detected in some scenarios of the fresh‐whole and frozen FVH sectors as well as Salmonella, pathogenic Escherichia coli and norovirus in the fresh‐cut and frozen FVH sector. Additionally, inadequate or improper monitoring systems resulted in either excessively high or insufficient disinfectant concentrations in the water, which, when too low, failed to sufficiently reduce the microbial load. The literature review revealed a tendency to: focus on leafy greens, use chlorine‐based disinfectants, and employ chemical oxygen demand (COD) as the primary physico‐chemical parameter, with total dissolved solids (TDS) and turbidity considered to a lesser extent, as indicators of water quality. Additionally, dynamic mass balance modelling was used to interpret experimental data from literature and FBOs. The model was fundamental to estimate key unknown parameters, predict the microbial contamination and accumulation of organic matter and allowing to simulate “what‐if scenarios.”

Published: January 2025

En este artículo se propone un nuevo índice de heterogeneidad que compara dos vectores, uno de observación y otro el esperado. Un caso particular resulta cuando el vector esperado tiene las mismas entradas en todos sus elementos, entonces, el índice propuesto resulta ser de desigualdad. La construcción geométrica y analítica del índice propuesto le confiere robustez matemática, además de su amplia gama de aplicaciones en distintas disciplinas como economía, estadística y sociología. En este trabajo hemos aplicado el índice en tópicos como el reparto de bienes, el desarrollo humano y el salario mínimo, obteniéndose resultados bastantes satisfactorios.
Narrativas de ficción para el análisis del imaginario social del docente y/o experto en química
Authors: Cuevas Romo Julio
Published: January 2025

En este aporte se analizan las narrativas de ficción como un recurso didáctico para reflexionar sobre procesos vinculados a la enseñanza de las ciencias, en específico sobre la enseñanza de la química. A partir de una selección de narrativas y personajes populares, tanto actuales como de hace algunas décadas, se sistematizan los imaginarios sociales que son presentados en productos como cine, series de televisión o el cómic. Se utilizan posteriormente algunos planteamientos de expertos como Pozo y Gómez (2004) sobre lo que implica el enseñar química y el perfil del profesional en su enseñanza, para contrastarlos con los imaginarios sociales detectados, analizando si estas narrativas de alto consumo, como pueden ser la serie Breaking Bad o la saga cinematográfica de Harry Potter, nos refuerzan estereotipos sobre la química o nos ayudan a aproximarnos a una visión más realista, resaltando el potencial didáctico del análisis.
