Authors: Xie Wenhui , Liu Yanli , Lin Juntang
Published: October 2023

“All in one” organic–inorganic nanocomposites with high biocompatibility and excellent physicochemical properties have recently attracted special attention in cancer imaging and therapy. Combination of organic and inorganic materials confers the nanocomposites with superior biocompatibility and biodegradability of organic materials, as well as magnetic, mechanical, and optical properties of inorganic materials. Increased endeavors have been made to produce diverse organic–inorganic nanocomposites and investigate their potential applications in cancer treatment. Thus, a systematic review of research progresses of diverse organic–inorganic nanocomposites in cancer imaging and therapy is indispensable. Following a brief overview of nanocomposites synthesis, classification, and functionalization, the current review is focused on comprehensively summarizing representatives of both organic–inorganic nanoscale nanocomposites (including organic-silica, organic-carbon, organic-quantum dots, organic-platinum family metals, organic-gold, organic metal oxides, and other nanocomposites) and organic–inorganic molecular nanocomposites (including metal-organic frameworks, organosilica nanoparticles, and amorphous metal coordination polymer particles), and further analyzing their working mechanism in cancer imaging and therapy. Finally, the challenges and future perspectives of organic–inorganic nanocomposites are addressed for promoting their developments and clinical application in cancer treatment.
Exploring Twenty-First-Century Catholic Traditionalist Resistance Movement through Digital Cartoons of Pope Francis
Authors: Guzek Damian , Słomka Jan , Cieslik Emma
Published: October 2023

Ever since cartoons were created as a medium of political and social commentary, they have been used to both criticize and uplift religious communities. The anti-Catholic cartoons of Thomas Nast and Jack Chick are easily recognizable, but interestingly, among twenty-first-century Catholic communities in Europe and the United States, Catholics themselves have been creating caricatures of Pope Francis, a more left-leaning pope in favor of reinforcing post-Second Vatican Council modernizations. These digital cartoons are tangible examples of a radically traditional antagonistic Catholic counter-public. This study delves into how radical traditional Catholic communities, who argue that pre-Vatican II traditions are a more authentic form of Catholicism than that encouraged by the current Pope Francis, are using cartoons to voice their agenda. By drawing from discourse theoretical analysis and hermeneutics, we identify four themes of criticism and discontent surrounding the pope: exposing his “bad agency,” ridiculing papal values, unveiling Francis’ “polarized and unbalanced” behavior, and expressing his predatory attitude toward representatives of Catholic traditionalism. Ultimately, we see these cartoons as the product of an antagonistic and anti-Pope Francis force internal to the Church, hypermediation without sources to public actions, and the digital milieu based on modernity in technology.

To be is not to inhabit: Yuri M. Lotman’s Ulysses and his transhumanist context
Authors: Váša Ondřej
Published: October 2023

This essay contextualizes the Dantean figure of Ulysses, as conceived by Yuri M. Lotman, and draws this key figure of modernity into a network of mutually interconnected discourses: primarily transhumanist visions of the human future in space, which nevertheless arise from the specifically modern epistemic dimension of “restlessness,” and intertwine with post-war astronautics, cyborg visions of human re-engineering, and revolutionary considerations of speculative realism. The key is Lotman’s emphasis on Ulysses as a figure of “energy of thought”; in this regard, the essay shows how the original poetic “decision,” embodied by the Ulysses figure, advocates implicit cruelty in the name of the future (treated as an inevitable fate), and how this decision generates a logical and progressively unfolding series of “inhuman” images of man situated in the universe as an event of saturation of matter with merciless intelligence.
The impatient gaze: on the phenomenon of scrolling in the age of boredom
Authors: Marek Jakub
Published: October 2023

In four major parts, this study investigates the phenomenon of scrolling. Its first task is to argue in favor of a specific quality of the experience of scrolling, distinguishing it from other forms of distraction, notably from the flow experience. Scrolling takes the shape of aimless drifting. Secondly, it investigates the phenomenon of scrolling against its relevant historical, economic, social, and cultural backdrop, with the intention of understanding scrolling as a typical phenomenon of today, rather than subscribing to a biased and superficial critique of its wastefulness or outright pathological character. The third part presents a comprehensive analysis of the temporal makeup of scrolling. Its temporality is expressed in the specific impatience of scrolling. Furthermore, scrolling amounts to a temporal reduction in the sense of favoring the present moment (and suppressing the temporal dimensions of the past and the future). The reductiveness of scrolling pertains to the semantic content as well. I argue that scrolling does not allow for certain experiences (such as, e.g., profound sadness). The temporality of scrolling is one of experiencing lived time as the permanence of passing. In the last section, I connect scrolling to boredom, and argue that scrolling accomplishes the task of allowing for an existential distractedness. In conclusion, I propose a nuanced evaluation of scrolling: in a Pascalian sense, scrolling responds to a profoundly human need of distraction. Yet I find scrolling dangerous in how easily available such distraction becomes, and in how it accustoms the users to a reductive existential experience. Scrolling, unlike art (but also, in principle, photography, movies, books), shields the user from challenging and enriching experiences.

Authors: Pashanova Olga , Zubko Elena , Aringazina Raisa , Yumashev Alexey
Published: October 2023

The research on the influence of antioxidant vitamins C and E on the catalytic activity of cytochrome P450 3A4 in electrochemical experiments is relevant, as they are widely used as additional biologically active substances in human diets and can affect biochemical processes in the body. Understanding these effects is of significant importance for pharmacology and medicine. The purpose of this study is to investigate how antioxidant vitamins C and E impact the catalytic activity of cytochrome P450 3A4 within the framework of electrochemical experiments. The voltammetry was performed in the presence of potassium phosphate buffer of neutral pH value (0.2 M) and 0.5 M erythromycin solution (Er). The ratio between the measures of current obtained in the presence of O2 and Er was 2.10 ± 0.09 (100 %, P < 0.05). With vitamin C and Er, it corresponded to 2.80 ± 0.12 (133 %, P < 0.05). The voltammograms of Cyt with Dic show a higher current stimulated by ascorbic acid. The effect of vitamin C on the H-dimethylation process of Er was investigated with a spectrophotometer (value 408 nm). The catalytic current of cytochrome P450 3A4 in the presence of diclofenac was stimulated by ascorbic acid, the effect of which on the N-demethylation of erythromycin was studied spectrophotometrically at 408 nm based on the formation of formaldehyde using the acetylacetone reagent. The obtained results suggest the potential impact of antioxidant vitamins not only on the stimulation of electrochemical reduction of cytochrome P450 3A4 but also on the clinical metabolism of substrates in patients. These findings provide valuable insights for further clinical investigations aimed at predicting the risk of drug interactions with antioxidants.
A wall or a road? A remote sensing-based investigation of fortifications on Rome's eastern frontier
Authors: Casana Jesse , Goodman David D. , Ferwerda Carolin
Published: October 2023

During a pioneering aerial survey of the Near East in the 1920s, Father Antoine Poidebard recorded hundreds of fortified military buildings that traced the eastern frontier of the Roman Empire. Based on their distribution, Poidebard proposed that these forts represented a line of defence against incursions from the east. Utilising declassified images from the CORONA and HEXAGON spy satellite programmes, the authors report on the identification of a further 396 forts widely distributed across the northern Fertile Crescent. The addition of these forts questions Poidebard's defensive frontier thesis and suggests instead that the structures played a role in facilitating the movement of people and goods across the Syrian steppe.
The Effect of a Novel Weight-Supported Kinetic Chain Resistance Training Program on Proximal Core Muscular Endurance, Trunk-to-Arm Muscular Power, and Bat Swing Speed

Published: October 2023

Palmer, TG, and McCabe, M. The effect of a novel weight-supported kinetic chain resistance training program on proximal core muscular endurance, trunk-to-arm muscular power, and bat swing speed. J Strength Cond Res 37(11): 2130–2140, 2023—Muscular stability and muscular power at the proximal core segments of the pelvis, spine, and trunk are essential attributes in maximizing bat swing speed in the sport of softball. Weight-supported kinetic chain resistance training (WsKC) is a novel closed kinetic chain technique that provides synergistic multiplanar stressors to the proximal core segments via the lower and upper extremities while limiting joint compression and sheer forces throughout the kinetic chain. The aim of this study was to assess the effect a 7-week preseason WsKC program would have on an isometric muscular endurance plank, trunk-to-arm peak muscular power (TAPP), trunk-to-arm peak velocity (TAPV), and bat swing speed (BSS) compared with a traditional isotonic weight resistance training program. Twenty-seven female high school softball players (age = 16 years, height = 167.6 cm, body mass = 62.86 kg) were assigned in a blocked randomization to one of 2 groups: a standing weight-supported kinetic chain resistance training (WsT) group (n = 13) or a pseudo-control traditional isotonic training (TT) group (n = 14). The WsT group had significant improvements (p < 0.05) for the isometric endurance plank (p = 0.001), TAPP (p = 0.002), TAPV (p = 0.001), and BSS (p = 0.02) compared with the TT group. The training effect size (ES) was large for the WsT group for all variables (ES = 1.0–7.4) and small to moderate for a majority of the TT variables (ES = 0.06–0.47). The simultaneous improvement in the isometric endurance plank, trunk-to-arm rotations, and BSS indicates that the WsKC contributed to subsequent improvements in BSS in high school softball players.

Redshaw, AS, Carrick-Ranson, G, Bennett, H, Norton, KI, and Walker, A. Effect of aging on movement quality in Australian urban firefighters. J Strength Cond Res 37(11): e601–e608, 2023—Adequate levels of movement quality (MQ) are required to safely perform occupational tasks in physically demanding and hazardous professions such as firefighting. Although it is well established that MQ deteriorates with age in population studies, there is conflicting evidence in older tactical populations. This study sought to examine the relationship between age and MQ in Australian urban firefighters. The impact of physical activity, injury history, and body mass index on MQ were also explored. The MQ of 324 professional Australian urban firefighters was assessed using MovementSCREEN MQ assessment tool. Scores of whole-body MQ ranged from 35.3 to 82.6 (0–100 scale), with a mean score of 59.2 ± 10.0. There was a moderate, negative association between MQ and age (r = −0.500; p ≤ 0.001), with those older than 50 years of age having significantly lower scores of MQ than their younger counterparts (p ≤ 0.001). Secondary analysis found that higher body mass index (r = −0.285; p ≤ 0.001), lower habitual physical activity levels (r = 0.165; p ≤ 0.003), and the presence of any musculoskeletal injury in the previous 12 months (p = 0.016) had significant negative effects on composite MQ. Firefighters older than 50, obese, and engaging in low levels of physical activity should be considered a high priority for functional strength training interventions to maintain adequate MQ throughout their careers.

Valdes, O, Inzulza, S, Collao, N, Garcia-Vicencio, S, Tufano, JJ, Earp, J, Venegas, M, and Peñailillo, L. Eccentric cycling is an alternative to Nordic hamstring exercise to increase the neuromuscular function of knee flexors in untrained men. J Strength Cond Res 37(11): 2158–2166, 2023—Nordic hamstring exercise (NHE) has been proposed to reduce knee flexor (KF) injuries. However, submaximal alternatives to NHE are necessary for the clinical or weaker population. The aim of this study was to compare the effects of Nordic hamstring training (NHT) and eccentric cycling (ECC) training on the neuromuscular function of the KF. Twenty healthy men (27.7 ± 3.5 years) were randomly assigned into 2 groups that performed 10 training sessions (2–3 sessions·week−1) of either NHT (n = 10) or ECC (n = 10). Maximal voluntary isometric contraction of the KF and knee extensor (KE) muscles (MVICKF and MVICKE) was measured, and the hamstring/quadriceps strength (H/Q) ratio was calculated. Furthermore, changes in NHE maximum reaction force (NHE-MRFKF), NHE break-point angle (NHE-BPA), and muscle activity of the semitendinosus (STEMG) and biceps femoris (BFEMG) during the NHE after the interventions were compared. Although no group × time effects were observed (p = 0.09–0.70), but time effects were found for all variables. Pairwise comparisons revealed that MVICKF (+16.9%; p = 0.02), H/Q ratio (+11.8%; p = 0.01), NHE-MRFKF (+19.8%; p = 0.005), and NHE-BPA (+30.8%; p = 0.001) increased after ECC, whereas NHE-MRFKF (+9.7%; p = 0.003), NHE-BPA (+35.5%; p = 0.0002), and STEMG (+33.7%; p = 0.02) increased after NHT. A group × time effect was observed (p = 0.003) in BFEMG, revealing an increase only after ECC (+41.1%; p < 0.0001). Similar neuromuscular adaptations were found after both training modalities. Therefore, ECC provides similar adaptations as NHT and may serve as an alternative form of KF training for those unable to perform NHE.
Self-Massage Techniques for the Management of Pain and Mobility With Application to Resistance Training: A Brief Review

MacLennan, M, Ramirez-Campillo, R, and Byrne, PJ. Self-massage techniques for the management of pain and mobility with application to resistance training: a brief review.J Strength Cond Res37(11): 2314–2323, 2023—Fascial restrictions that occur in response to myofascial trigger points (MTrP), exercise-induced muscle damage (EIMD), and delayed onset of muscle soreness (DOMS) cause soft tissue to lose extensibility, which contributes to abnormal muscle mechanics, reduced muscle length, and decrements in joint range of motion (ROM) and actively contributes to musculoskeletal pain. Resistance training and in particular, weightlifting movements have unique mobility requirements imperative for movement efficacy and safety with ROM restrictions resulting in ineffective volume and intensity tolerance and dampened force output and power, which may lead to a failed lift or injury. Self-massage (SM) provides an expedient method to promote movement efficiency and reduce injury risk by improving ROM, muscular function, and reducing pain and allows athletes to continue to train at their desired frequency with minimal disruption from MTrPs-associated adverse effects. Thus, the aim of this review was to determine the efficacy of various self-massage tools in managing pain and mobility and to explore the potential benefits of SM on resistance training performance. Many SM devices are available for athletes to manage ROM restrictions and pain, including differing densities of foam rollers, roller massagers, tennis balls, and vibrating devices. To attenuate adverse training effects, a 10-to-20-minute bout consisting of 2-minute bouts of SM on the affected area may be beneficial. When selecting a SM device, athletes should note that foam rollers appear to be more effective than roller massagers, with vibrating foam rollers eliciting an increased reduction to pain perception, and tennis balls and soft massage balls were shown to be efficacious in targeting smaller affected areas.

Published: October 2023

The availability of quality materials for the construction of pavements has been a problem in some regions. This scarcity enforced geosynthetic materials as one of the quests for su1stainability in the pavement industry. This study attempted to stabilize marginal (tunnel muck, reclaimed asphalt pavement material) and industrial waste (zinc slag) materials by employing high density polyethylene geocell to appraise the effectiveness of geosynthetic reinforcement in enhancing the characteristics of pavement materials and mitigating their rutting. The cyclic plate load tests are performed on marginal and industrial waste material with geocell-reinforced and unreinforced base layers over black cotton soil as the subgrade. The tests were conducted following the trapezoidal loading pattern with a 0.77-Hz frequency. The geocell-reinforced pavement performance was evaluated for resilient deformation, accumulated permanent deformation, rut depth reduction, traffic benefit ratio, and base layer thickness reduction. The mechanistic empirical pavement design guide (MEPDG) permanent deformation performance (PDP) model framework was used to predict the accumulated permanent deformation in unbound granular layers and to differentiate the rutting performance in geocell-reinforced and unreinforced sections. This study determined the material constants of the MEPDG PDP model for marginal and industrial waste materials used in the pavement section for quantifying the reduction in base layer thickness.

Published: October 2023

Polydimethylsiloxane (PDMS) is widely used for microfluidic and biomedical applications because of its chemical inertness and affordability. However, its low surface energy limits its adhesion properties, thus necessitating mandatory surface activation, via plasma treatments or chemical processing, especially for improving its hydrophilicity. In this study, we employed an atmospheric pressure plasma jet (2 W) in order to enhance the PDMS surface adhesion for application in microfluidic devices. Treatment variables, including exposure and recovery time and adhesion quality, were investigated. It was possible to achieve a minimum exposure time of 15 s/cm2 for thin PDMS (sheet, 250 μm) and 30 s/cm2 for thick (resin, 3 mm) PDMS. A robust and efficient methodology for scaling the jet system treatment of larger areas was developed. Additionally, we examined the effect of ambient humidity on the plasma treatment. Results showed that water adsorption on PDMS-treated surfaces indicated a difference between the well-established contact angle method for determining surface hydrophilicity (and thus, its adhesion) and the real adhesion properties of the treated surfaces.

The immune system is in place to assist in ensuring tissue homeostasis, which can be easily perturbed by invading pathogens or nonpathogenic stressors causing tissue damage. Extracellular nucleotides are well known to contribute to innate immune signaling specificity and strength, but how their signaling is relayed downstream of cell surface receptors and how this translates into antiviral immunity is only partially understood. Here, we systematically investigated the responses of human macrophages to extracellular nucleotides, focusing on the nucleotide‐sensing GPRC receptors of the P2Y family. Time‐resolved transcriptomic analysis showed that adenine‐ and uridine‐based nucleotides induce a specific, immediate, and transient cytokine response through the MAPK signaling pathway that regulates transcriptional activation by AP‐1. Using receptor trans‐complementation, we identified a subset of P2Ys (P2Y1, P2Y2, P2Y6, and P2Y11) that govern inflammatory responses via cytokine induction, while others (P2Y4, P2Y11, P2Y12, P2Y13, and P2Y14) directly induce antiviral responses. Notably, P2Y11 combined both activities, and depletion or inhibition of this receptor in macrophages impaired both inflammatory and antiviral responses. Collectively, these results highlight the underappreciated functions of P2Y receptors in innate immune processes.

Published: October 2023

Due to the electrification of modern vehicles the role of the electric drive is growing as the main mover. In conditions of increasing requirements for the safety controllability and energy efficiency of a vehicle on electric traction,it is actual to take into account the dynamic properties of a vehicle in various driving modes when developing an automatic control system. In the work it is investigated the influence of the mass center position on the redistribution of forces during acceleration on a straight-line section. Taking into consideration the position of the mass center in the control system allows redistributing the desired moment to the wheels with better adhesion to the surface, which increases the safety and controllability of the vehicle, as well as minimizes energy costs on wheels with the worst adhesion. The aim of the work is to investigate the influence of the mass center position on the dynamics of a vehicle with full, rear and front wheel drive using computer simulation. The mathematical description includes analytical expressions for the redistribution of the support reactions for each of the wheels, which makes it possible, on their basis, to carry out computer simulation of the electric vehicle acceleration on a straight-line section. For the indicated types of vehicle drives, a computer model has been developed that includes, in the automatic control system for torque redistribution, the coordinates of the mass center position, which are converted on the basis of analytical expressions into the physical parameters of the system.Computer simulation of acceleration from zero to one hundred km/h with full pressing of the accelerator pedal for nine different positions of the mass center and three types of drive was carried out. Data were obtained on the change in accelerations, support reactions and torque of wheels during acceleration at various mass center positions. Based on the results obtained, the most preferable coordinates of the mass center for each type of drive from the point of view of the acceleration dynamics on a straight section were determined. The developed computer model can be used to study the dynamics of an electric vehicle when cornering, as well as to study energy indicators in all dynamic driving modes.

Authors: Udayasree Bakigari , Kumar G. Shravan
Published: October 2023

The sustainable design of concrete is of paramount importance in the construction industry as it strives to minimize environmental impact while maintaining performance and durability. A key aspect of this endeavor is the assessment and integration of industrial waste materials and additives into concrete formulations. Concrete is the most frequently used construction material in the world.  Each year, over ten billion tonnes of concrete are produced, resulting in the depletion of natural resources and a colossal carbon footprint. One of the primary objectives of contemporary concrete technology is to reduce the use of Portland cement and natural fine aggregates by partially substituting them with various waste materials and industrial byproducts. This paper summarises the findings of a study in which steel slag aggregate, silica fume and glass refuse were successfully used to partially replace river sand and Portland cement.
Academic Burnout, Self-Efficacy, and Emotional Stress Reaction of Learners: Conditional Process Analysis

Published: October 2023

Academic burnout lessens learners' insights into their ability to study and their academic achievement, as well as has a detrimental effect on their physical and mental health, which may be tied to an emotional stress reaction. The current study aimed to assess academic burnout, self-efficacy, and emotional stress reaction of sandwich learners through conditional process analysis. For the study, a descriptive survey with a sample size of 385 students who represented a reachable population of 1, 925 respondents was used. Data was collected using a questionnaire with r = .776 through online Google format. Frequencies, percentages, the Pearson product-moment r, and a structural equational model were used to analyze the data. According to the study, there are three levels of self-efficacy for students. However, the study found that most learners have moderate self-efficacy. The study also revealed that there is no substantial relationship between learners’ self-efficacy and their emotional stress reactions. It was again found that self-efficacy significantly moderates the influence of academic burnout on emotional stress reactions. Finally, the study found that self-efficacy does not significantly mediate the influence of academic burnout on emotional stress reactions. After these predominant findings, it was concluded that the majority of learners tend to exhibit moderate self-efficacy. This implies that while they possess a certain degree of confidence in their abilities, there is room for improvement and growth in terms of their self-belief. It is advised that educational institutions and teachers concentrate on interventions and tactics to improve students' self-efficacy in light of these findings.

All his life I. Gasprinsky was defending the interests of the Crimean Tatars, Mus- lims and societies living in conditions of colonial slavery. Gasprinsky was one of the most outstanding thinkers of the Turkic world. UNESCO declared 2014 the year of Ismail Gasprinsky for his contribution to education and philosophy.

The study showed that the modern interest in I. Gasprinsky is caused by the increasingly unfolding globalization and the formation of an ecological-humanistic civilization, as a new form of preserving cultural diversity in its entirety.
Size matters: identity of culturally important herrings in northeastern Brazil

Fishery statistics are mainly made by recording the popular fish names, which is later translated into scientific identification. However, these names often either refer to a species group and/or vary along their distribution, increasing identification uncertainty. Species that have cultural value for traditional communities are known as culturally important species (CIS). Herein, we assessed Fishers’ Ecological Knowledge to investigate small-silvery herrings (ginga) used as part of a traditional dish \ginga com tapioca", that is recognized as a cultural heritage in the Brazilian northeastern. Through 103 interviews conducted in six communities in three states, we determined that ginga, although a name known elsewhere, is only traded as such in the metropolitan area of Natal. In this region, ginga is caught with drift net and deemed profitable by fishers. We identified both over- and under-differentiation, with ginga recognized by fishers as five, and sold as three main species, namely Opisthonema oglinum, Harengula sp., and Lile piquitinga. The larger specimens of two of those species (O. oglinum and Harengula sp.) were also traded as sardines. We found that most individuals sold as ginga were juveniles, which might impact the recruitment of some fish species. Due to its unique cultural relevance to the local community of Natal, ginga could be considered a CIS, which could aid future management or conservation measures.

Ethnoichthyology has been highlighting in several regions of the world, due to the collaboration of studies that seek to understand the traditional or local ecological knowledge about different uses and meanings of fish among different human groups. Therefore, we present a systematic review of the literature concerning the current situation of ethnoichthyological studies in Brazil. We examine the temporal and spatial citation trends in Brazil, as well as who are the research actors and the thematic areas covered in the articles. In all, 177 published articles related to the topic were found in Brazil. The number of published articles increased significantly in time, with most studies concentrated in the Northeast Region of the country (44.4%), especially in the state of Bahia (16.8%). The types of aquatic environments include both marine and freshwater, such as sea (46.3%) and rivers (70.2%). The articles mainly rely on the collaboration of artisanal fisherman (74.3%). The topic most frequently addressed in the studies was bio-ecological aspects of fish (33.8%). On the other hand, studies on morphological aspects (2.7%) represented the less frequently among the thematic areas. We concluded that ethnoichthyology is increasing significantly in Brazil. However, some issues needed to be better understand, especially the knowledge of the recreational fishermen, the morphological aspects of the fish species by local fishermen and there are few studies in South and Midwest in Brazil, which will indicate the future efforts to improve the species conservation and the resource management.
„Készíts amulettet, írd rá ezt a ráolvasást, majd akaszd a nyakába!”

Tanulmányunk a mezopotámiai orvosi-mágikus amulettek egyik sajátos csoportját, az agyaghengeres amuletteket vizsgálja. E tárgyak alakja a kőből készült pecséthengerekéhez hasonló, ám agyagból készültek, s a felületükön ráolvasások szövege olvasható, melyek sokszor az amulettek tulajdonosait is megnevezik. Munkánk célja a választott tárgytípus valamennyi darabjának összegyűjtése, azok osztályozása és elemzése a rajtuk szereplő feliratok alapján, továbbá azon rítusleírások tanulmányozása, amelyek ezeknek az amuletteknek az alkalmazását említik. Vizsgáljuk e tárgyak kutatástörténetét, régészeti kontextusát, valamint a tulajdonosaikat. A rajtuk szereplő ráolvasások egyéb, kőből készült amuletteken és pecséthengereken is megjelennek, amelyeket a munkánk végén található Appendixben gyűjtöttünk össze.
Die lieblichste der lieblichsten Gestalten

Ez a rövid írás néhány jellemző példával mutat rá a szerelmi költészet egyik motívumának (’erotikus kizárólagosság’) egyszerre ősi és folytonos mivoltára. A kiindulópont Goethe egy helye, innen vezet az út a görög és a latin költészethez, hogy a végén modern példákkal zárjuk ezt a rövid, ám annál kalandosabb áttekintést. A vizsgált motívum ilyenformán korokon és műfajokon átívelő örök emberi gondolatnak és kifejezési formának bizonyul.

Pensar el alimento: experiencia de investigación creación participativa como medio de transformación comunitaria
Authors: De la Horra Ana Elizabeth , Grill Judith Betsabé
Published: October 2023

El siguiente trabajo presenta una experiencia de investigación creación entre mujeres trabajadoras de un comedor y huerta comunitarios de un barrio vulnerable de la ciudad de Córdoba Capital (Argentina). Específicamente, propone analizar cómo los aspectos metodológicos empleados permitieron el desarrollo de la experiencia desde una praxis participativa y presentar los resultados del proceso. La metodología se planteó como cíclica y progresiva y desde las premisas del diálogo de saberes, el diseño otro y el arte participativo. En las instancias de investigación y reflexión se utilizó el fotovoz, y en las etapas de experimentación y diseño se usaron técnicas como collage, dibujo y xilografía. Como resultado del trabajo realizado se crearon tres productos desde un diseño otro: un logo, recetarios comunitarios y una producción audiovisual, que recuperaron lo comunitario y permitieron pensar y materializar otras realidades posibles. El arte y el diseño participativo aportaron elementos que, si bien presentaron límites difusos, posibilitaron la investigación y reflexión en torno a imaginarios sociales relacionados al alimento y al trabajo comunitario; se fortalecieron los vínculos sociales entre las participantes y la comunidad próxima, y se creó contenido cultural y saber específico.
Narraciones de mujer sobre la casa rururbana de Riosucio (Caldas): experiencias de otras maneras del diseño desde un proceso de investigación creación
Authors: Arango Marín Miguel , Cardona González Marcela
Published: October 2023

En este artículo presentamos algunos de los resultados de una investigación creación que integra diversas disciplinas de las áreas creativas, humanidades y ciencias sociales, que llevamos a cabo en la zona rururbana del municipio de Riosucio (Caldas) en Colombia y que, a nuestro entender, se asienta en otras maneras de pensar-hacer desde un saber diseñístico contextualizado. En esencia, desde esta investigación creación buscamos dar cuenta de los saberes de la domesticidad cotidiana y territorializada que reposa en las narraciones y las prácticas de tres grupos de mujeres con los que trabajamos de manera colaborativa con el objetivo de renarrar, con ellas, aquello que saben y ponen en práctica todos los días para cuidar y producir sus casas y sus territorios. Así, en este documento avanzamos hacia la consecución de este propósito desde tres coordenadas relacionadas: (i) una epistemológica, que apunta a la materialización de otras maneras de hacer del diseño, (ii) una conceptual, para aproximarnos a esos saberes que queremos reconocer y que hemos denominado el sistema Casa-Habitante-Artefacto (C-H-A) y (iii) una metodológica, que centra la atención en las formas en que ese sistema C-H-A condujo al trabajo colaborativo con las mujeres participantes de la investigación, consiguiendo recabar aquellos saberes domésticos que hacen la casa y, en parte, el territorio. Con lo anterior, concluimos que las narraciones de las mujeres con las que trabajamos son una voz resonante que se suma al sostenimiento cultural y ambiental de la vida cotidiana de estos territorios. Y que los diseños otros se resuelven más en las propuestas afincadas en la conversación con grupos de personas situadas y territorializadas, que en el plano de la discusión experta y metadiscursiva del diseño. Porque cuando las experiencias del diseño (otras) son tangibles, pueden ser identificadas, evaluadas y criticadas.
