The Confucian Contingency Model: Person, Agency, and Morality
Authors: D'Ambrosio Paul J.
Published: February 2024

Abstract: The Analects and the Mencius are among the most influential early Confucian texts. They emphasize the importance of moral self-cultivation. The individual is expected to identify what is good, and freely choose it regardless of their internal predispositions or external conditions. Curiously, in their philosophical frameworks they do not posit anything outside of contingencies. This means there is no non-contingency-based notion of "good" or "agency." This paper contributes to the current discourse by explaining how morality and agency can be possible in a completely contingent system. Instead of positing a pregiven principle, self, will, or even capacity for agency, I will argue that Confucian texts assume that morality and agency emerge out of contingencies. As such, morality and agency are categorically distinct from contingencies, and are thereby able to reflect on them, without being ultimately sourced from any power outside of contingencies.
Catharsis, Transtextuality, and Poetic Persona in Pessoa-Campos's 'Saudação a Walt Whitman'
Authors: Brocca Josué
Published: February 2024

Abstract: This article presents a comparative approach to understanding the literary characterization of Fernando Pessoa's heteronym, Álvaro de Campos, in relation to Walt Whitman's poetic persona. Two main axes structure it. The first makes a brief introduction to Fernando Pessoa's drama-em-gente and highlights the distinctive role of Álvaro de Campos in this system through a bibliographical and critical review. The second consists of a reading of the 'Saudação a Walt Whitman' as a poem of catharsis through stylistic comparison, Gérard Genette's concept of transtextuality, and the topology of identification in the reception of Hans Robert Jauss. Throughout the analysis, I contrast the poetic personas of Campos and Whitman in terms of style, I point out the fundamental devices with which Campos identifies in Whitman's persona, and I refer to the presence of transtextual references to Whitman's work in Campos's poem. Throughout these pages, I also raise suggestions about how the cosmopolitan themes of Whitman's transcendental poems are derived and changed to shape a part of Pessoa's avant-garde poetics. Resumo: O presente artigo apresenta uma abordagem comparativa para compreender a caracterização literária do heterónimo de Fernando Pessoa, Álvaro de Campos, em relação à persona poética de Walt Whitman. Dois eixos principais o constroem. O primeiro faz uma breve introdução ao drama-emgente de Fernando Pessoa e destaca o papel marcante de Álvaro de Campos nesse sistema por meio de revisão bibliográfica e crítica. O segundo consiste numa leitura da 'Saudação a Walt Whitman' como um poema de catarse através da comparação estilística, do conceito de transtextualidade de Gérard Genette e da topologia da identificação na recepção de Hans Robert Jauss. Ao longo da análise, contrasto as personas poéticas de Campos e Whitman em termos de estilo, aponto os dispositivos fundamentais com os quais Campos se identifica na persona de Whitman e refiro-me à presença de referências transtextuais à obra de Whitman no poema de Campos. Ao longo destas páginas, também levanto sugestões sobre como os temas cosmopolitas dos poemas transcendentais de Whitman derivam e mudam para dar forma a uma parte da poética de vanguarda de Pessoa.

Published: February 2024

The kidney is an important organ for excreting metabolic waste and maintaining the stability of the body’s internal environment. The renal function involves multiple complex and fine structures in the whole kidney, and any change in these structures may cause impaired nephric function. Consequently, achieving three-dimensional (3D) reconstruction of the entire kidney at a single-cell resolution is of significant importance for understanding the kidney’s structural characteristics and exploring the pathogenesis of kidney diseases. In this paper, we propose a pipeline from sample preparation to optical microscopic imaging of the entire kidney, followed by data processing for 3D reconstruction of the whole mouse kidney. We employed transgenic fluorescent labeling and propidium iodide (PI) labeling to obtain detailed information about the vascular structure and cytoarchitecture of the kidney. Subsequently, the entire mouse kidney was imaged at submicron-resolution using high-definition fluorescent micro-optical sectioning tomography (HD-fMOST). Finally, we reconstructed the structures of interest through various data processing methods on the original images. This included detecting glomeruli throughout the entire kidney, as well as the segmentation and visualization of the renal arteries, veins, and three different types of nephrons. Our method provides a powerful tool for studying the renal microstructure and its spatial relationships throughout the entire kidney.
Phase fluctuations-induced bit error ratio of deep-space optical communication systems during superior solar conjunction

Published: February 2024

Deep-space optical communication has garnered increasing attention for its high data transfer rate, wide bandwidth, and high transmission speed. However, coronal plasma turbulence severely degrades optical signals during superior solar conjunction. In this study, we introduce the models for plasma density and generalized non-Kolmogorov turbulence power spectrum. Based on these models, we derive the variance of the phase fluctuations with the assistance of the Rytov theory in the weak turbulence regime involving various variables, such as turbulence outer scale, spectral index, relative fluctuation factor, and wavelength. Subsequently, we evaluate the bit error ratio (BER) performance of the deep-space optical communication system, considering phase fluctuations and intensity scintillations, under binary phase shift keying modulation. Numerical calculations reveal that small heliocentric distance, large relative fluctuation factor and spectral index, could induce severe phase fluctuations and high BER. Fortunately, the effects of the plasma irregularities on the BER performance can be mitigated by short optical wavelength under large outer scale.

Published: February 2024

We demonstrate a novel, to the best of our knowledge, high-temperature pressure sensor based on a highly birefringent fiber Bragg grating (Hi-Bi FBG) fabricated in a dual side-hole fiber (DSHF). The Hi-Bi FBG is generated by a femtosecond laser directly written sawtooth structure in the DSHF cladding along the fiber core through the slow axis (i.e., the direction perpendicular to the dual-hole axis). The sawtooth structure serves as an in-fiber stressor and also generates Bragg resonance due to its periodicity. The DSHF was etched by hydrofluoric acid to increase its pressure sensitivity, and the diameter of two air holes was enlarged from 38.2 to 49.6 µm. A Hi-Bi FBG with a birefringence of up to 1.8 × 10−3 was successfully created in the etched DSHF. Two distinct reflection peaks could be observed by using a commercial FBG interrogator. Moreover, pressure measurement from 0 to 3 MPa at a high temperature of 700°C was conducted by monitoring the birefringence-induced peak splits and achieved a high-pressure sensitivity of −21.2 pm/MPa. The discrimination of the temperature and pressure could be realized by simultaneously measuring the Bragg wavelength shifts and peak splits. Furthermore, a wavelength-division-multiplexed (WDM) Hi-Bi FBG array was also constructed in the DSHF and was used for quasi-distributed high-pressure sensing up to 3 MPa. As such, the proposed femtosecond laser-inscribed Hi-Bi FBG is a promising tool for high-temperature pressure sensing in harsh environments, such as aerospace vehicles, nuclear reactors, and petrochemical industries.
Turbulence mitigation of four mode-division-multiplexed QPSK channels in a pilot-assisted self-coherent free-space optical link using a photodetector array and DSP-based channel demultiplexing

Published: February 2024

In this Letter, we demonstrate turbulence mitigation of four mode-division-multiplexing (MDM) quadrature-phase-shift-keying (QPSK) channels in a pilot-assisted self-coherent free-space optical (FSO) link using a photodetector (PD) array and digital signal processing (DSP)-based channel demultiplexing. A Gaussian pilot beam is co-transmitted with four 1-Gbaud QPSK channels carried by four orbital angular momentum (OAM) modes. The pilot beam experiences similar turbulence-induced wavefront distortion to the data beams. At the receiver, the turbulence distortion is mitigated by its conjugate during the pilot–data mixing in a PD array. Subsequently, we demultiplex the four channels by applying in DSP a fixed matrix on the signals. Results show that our approach has <3-dB turbulence-induced power penalty at a 7% forward error correction (FEC) limit under a turbulence strength of 2

Published: February 2024

We observe that the modal field distribution of a dielectric slot waveguide closely resembles a magnetic dipole antenna. Such an aperture distribution traditionally demands metals, making it ill-suited to high frequencies due to excessive ohmic loss. By terminating a dielectric slot waveguide with a matched free-space interface, a compact all-dielectric radiating magnetic dipole is realized. In this way, we introduce general-purpose dipole antennas, which have long been a mainstay of RF and microwave ranges, into the realm of light wave photonic integrated circuits. The existence of the desired magnetic dipole aperture distribution is experimentally confirmed in the terahertz range, at ∼275 GHz, and good matching is evident in the ∼−25 dB reflection level. This is the electrically smallest radiator to ever be incorporated into an all-dielectric waveguiding platform.

Published: February 2024

Structured illumination microscopy (SIM) has been widely applied to investigate intricate biological dynamics due to its outstanding super-resolution imaging speed. Incorporating compressive sensing into SIM brings the possibility to further improve the super-resolution imaging speed. Nevertheless, the recovery of the super-resolution information from the compressed measurement remains challenging in experiments. Here, we report structured illumination microscopy with complementary encoding-based compressive imaging (CECI-SIM) to realize faster super-resolution imaging. Compared to the nine measurements to obtain a super-resolution image in a conventional SIM, CECI-SIM can achieve a super-resolution image by three measurements; therefore, a threefold improvement in the imaging speed can be achieved. This faster imaging ability in CECI-SIM is experimentally verified by observing tubulin and actin in mouse embryonic fibroblast cells. This work provides a feasible solution for high-speed super-resolution imaging, which would bring significant applications in biomedical research.
Factors associated with initial AstraZeneca vaccine knowledge, attitudes, and uptake among hospital nurses: A cross-sectional study in Ghana’s Upper East region
Authors: Atongu Simon Ferguson , Aninanya Gifty Apiung , Howard Natasha
Published: February 2024

The COVID-19 pandemic has caused over 171,657 confirmed cases and 1,462 deaths in Ghana, particularly among frontline health-workers involved in pandemic response. Prevention measures in Ghana include AstraZeneca ‘Covishield’ vaccination of health-workers, but research on factors affecting uptake of COVID-19 vaccines in Ghana were initially limited. Therefore, this study aimed to analyse knowledge, attitudes, and initial uptake of Covishield among nurses in the War Memorial Hospital in Navrongo, Upper East Region. We conducted a cross-sectional survey of 128 district hospital nurses using simple random sampling. We first calculated descriptive statistics and two composite variables summing either participant knowledge or attitude variables, with a threshold over 50% considered ‘sufficient’ or ‘positive’ respectively. We then analysed associations between demographic variables and Covishield knowledge, attitudes, or uptake using binomial logistic regression with a 95% confidence interval and p-value of <0.05 considered significant. All participants had heard of Covishield vaccine, with attitudes toward it generally positive (53%), and uptake high (72%). Reasons cited by the 28% unvaccinated included absence during vaccination, having already been infected with COVID-19, lack of trust in vaccine safety/efficacy, or pregnancy/breastfeeding. Education, residence, and family type were the only demographic factors significantly associated with nurses’ knowledge about, attitudes towards, or uptake of COVID-19 vaccination. While ‘positive’ attitude was significantly associated with higher odds of being vaccinated (AOR 4.75; 95%CI 1.59–14.1), ‘sufficient’ knowledge was not (AOR 1.33; 95%CI 0.53–3.32). This is the first study in Ghana’s resource-constrained Upper East region to examine health-worker perceptions of a novel vaccine and showed nurses’ knowledge, attitudes, and uptake of COVID-19 vaccination were good overall. Further research is needed to determine how best to address hesitancy and understand findings that attitudes appeared more relevant than knowledge for uptake. Findings are relevant for local health authorities in improving vaccine availability and strengthening emergency risk communication and management of adverse events following immunisation.
“Non-Eloquent” brain regions predict neuropsychological outcome in tumor patients undergoing awake craniotomy
Authors: Chohan Muhammad Omar , Flores Ranee Ann , Wertz Christopher , Jung Rex Eugene
Published: February 2024

Supratotal resection of primary brain tumors is being advocated especially when involving “non-eloquent” tissue. However, there is extensive neuropsychological data implicating functions critical to higher cognition in areas considered “non-eloquent” by most surgeons. The goal of the study was to determine pre-surgical brain regions that would be predictive of cognitive outcome at 4–6 months post-surgery. Cortical reconstruction and volumetric segmentation were performed with the FreeSurfer-v6.0 image analysis suite. Linear regression models were used to regress cortical volumes from both hemispheres, against the total cognitive z-score to determine the relationship between brain structure and broad cognitive functioning while controlling for age, sex, and total segmented brain volume. We identified 62 consecutive patients who underwent planned awake resections of primary (n = 55, 88%) and metastatic at the University of New Mexico Hospital between 2015 and 2019. Of those, 42 (23 males, 25 left hemispheric lesions) had complete pre and post-op neuropsychological data available and were included in this study. Overall, total neuropsychological functioning was somewhat worse (p = 0.09) at post-operative neuropsychological outcome (Mean = -.20) than at baseline (Mean = .00). Patients with radiation following resection (n = 32) performed marginally worse (p = .036). We found that several discrete brain volumes obtained pre-surgery predicted neuropsychological outcome post-resection. For the total sample, these volumes included: left fusiform, right lateral orbital frontal, right post central, and right paracentral regions. Regardless of lesion lateralization, volumes within the right frontal lobe, and specifically right orbitofrontal cortex, predicted neuropsychological difference scores. The current study highlights the gaps in our current understanding of brain eloquence. We hypothesize that the volume of tissue within the right lateral orbital frontal lobe represents important cognitive reserve capacity in patients undergoing tumor surgery. Our data also cautions the neurosurgeon when considering supratotal resections of tumors that do not extend into areas considered “non-eloquent” by current standards.
Influence of open-source virtual-reality based gaze training on navigation performance in Retinitis pigmentosa patients in a crossover randomized controlled trial
Authors: Neugebauer Alexander , Sipatchin Alexandra , Stingl Katarina , Ivanov Iliya , Wahl Siegfried
Published: February 2024

Methods

A group of RP patients (n = 8, aged 20-60) participated in a study consisting of two 4-week-phases, both carried out by the same patient group in randomized order: In the ‘training phase’, participants carried out a Virtual-Reality gaze training for 30 minutes per day; In the ‘control phase’, no training occurred. Before and after each phase, participants were tasked to move through a randomized real-world obstacle course. Navigation performance in the obstacle course as well as eye-tracking data during the trials were evaluated. The study is registered at the German Clinical Trials Register (DRKS) with the ID DRKS00032628.

Results

On average, the time required to move through the obstacle course decreased by 17.0% after the training phase, the number of collisions decreased by 50.0%. Both effects are significantly higher than those found in the control phase (p < 0.001 for required time, p = 0.0165 for number of collisions), with the required time decreasing by 5.9% and number of collisions decreasing by 10.4% after the control phase. The average visual area observed by participants increases by 4.41% after training, however the effect is not found to be significantly higher than in the control phase (p = 0.394).

Conclusion

The performance increase over the training phase significantly surpasses the natural learning effect found in the control phase, suggesting that Virtual-Reality based gaze training can have a positive effect on real-world navigation tasks for patients with RP. The training is available as work-in-progress open-source software.

Introduction

Ongoing changes in post resuscitation medicine and society create a range of ethical challenges for clinicians. Withdrawal of life-sustaining treatment is a very sensitive, complex decision to be made by the treatment team and the relatives together. According to the guidelines, prognostication after cardiopulmonary resuscitation should be based on a combination of clinical examination, biomarkers, imaging, and electrophysiological testing. Several prognostic scores exist to predict neurological and mortality outcome in post-cardiac arrest patients. We aimed to perform a meta-analysis and systematic review of current scoring systems used after out-of-hospital cardiac arrest (OHCA).

Materials and methods

Our systematic search was conducted in four databases: Medline, Embase, Central and Scopus on 24th April 2023. The patient population consisted of successfully resuscitated adult patients after OHCA. We included all prognostic scoring systems in our analysis suitable to estimate neurologic function as the primary outcome and mortality as the secondary outcome. For each score and outcome, we collected the AUC (area under curve) values and their CIs (confidence iterval) and performed a random-effects meta-analysis to obtain pooled AUC estimates with 95% CI. To visualize the trade-off between sensitivity and specificity achieved using different thresholds, we created the Summary Receiver Operating Characteristic (SROC) curves.

Results

24,479 records were identified, 51 of which met the selection criteria and were included in the qualitative analysis. Of these, 24 studies were included in the quantitative synthesis. The performance of CAHP (Cardiac Arrest Hospital Prognosis) (0.876 [0.853–0.898]) and OHCA (0.840 [0.824–0.856]) was good to predict neurological outcome at hospital discharge, and TTM (Targeted Temperature Management) (0.880 [0.844–0.916]), CAHP (0.843 [0.771–0.915]) and OHCA (0.811 [0.759–0.863]) scores predicted good the 6-month neurological outcome. We were able to confirm the superiority of the CAHP score especially in the high specificity range based on our sensitivity and specificity analysis.

Conclusion

Based on our results CAHP is the most accurate scoring system for predicting the neurological outcome at hospital discharge and is a bit less accurate than TTM score for the 6-month outcome. We recommend the use of the CAHP scoring system in everyday clinical practice not only because of its accuracy and the best performance concerning specificity but also because of the rapid and easy availability of the necessary clinical data for the calculation.
No influence of emotional expression on size underestimation of upright faces
Authors: Walsh Eamonn , Whitby Jack , Chen Yen-Ya , Longo Matthew R.
Published: February 2024

Faces are a primary means of conveying social information between humans. One important factor modulating the perception of human faces is emotional expression. Face inversion also affects perception, including judgments of emotional expression, possibly through the disruption of configural processing. One intriguing inversion effect is an illusion whereby faces appear to be physically smaller when upright than when inverted. This illusion appears to be highly selective for faces. In this study, we investigated whether the emotional expression of a face (neutral, happy, afraid, and angry) modulates the magnitude of this size illusion. Results showed that for all four expressions, there was a clear bias for inverted stimuli to be judged as larger than upright ones. This demonstrates that there is no influence of emotional expression on the size underestimation of upright faces, a surprising result given that recognition of different emotional expressions is known to be affected unevenly by inversion. Results are discussed considering recent neuroimaging research which used population receptive field (pRF) mapping to investigate the neural mechanisms underlying face perception features and which may provide an explanation for how an upright face appears smaller than an inverted one. Elucidation of this effect would lead to a greater understanding of how humans communicate.
Beyond traditional training: Integrating data from semi-immersive VR dual-task intervention in Parkinsonian Syndromes. A study protocol

Completing cognitive and motor tasks simultaneously requires a high level of cognitive control in terms of executive processes and attentional abilities. Most of the daily activities require a dual-task performance. While walking, for example, it may be necessary to adapt gait to obstacles of the environment or simply participate in a conversation; all these activities involve more than one ability at the same time. This parallel performance may be critical in the cognitive or motor load, especially for patients with neurological diseases such as Parkinsonian Syndromes. Patients are often characterized by a crucial impairment in performing both tasks concurrently, showing a decrease in attention skills and executive functions, thus leading to increased negative outcomes. In this scenario, the accurate assessment of the components involved in dual-task performance is crucial, and providing an early specific training program appears to be essential. The objective of this protocol is to assess cognitive and motor components involved in dual-task performance and create a training program based on ecological activities focusing on executive and motor functions. Thus, we will employ Virtual Reality to provide semi-immersive, multisensory, ecological, standardized, and realistic experiences for rehabilitative purposes in patients with Parkinsonian Syndromes, considering its high prevalence in aging and the incidence of motor and cognitive dysfunctions in this population. Moreover, we propose to integrate the great amount of different data provided by dual-task and Virtual Reality system, using machine learning techniques. These integrations may increase the treatment’s reliability in terms of better prognostic indexes and individualized training.
Pharmacogenomics of poor drug metabolism in greyhounds: Canine P450 oxidoreductase genetic variation, breed heterogeneity, and functional characterization

Published: February 2024

Greyhounds metabolize cytochrome P450 (CYP) 2B11 substrates more slowly than other dog breeds. However, CYP2B11 gene variants associated with decreased CYP2B11 expression do not fully explain reduced CYP2B11 activity in this breed. P450 oxidoreductase (POR) is an essential redox partner for all CYPs. POR protein variants can enhance or repress CYP enzyme function in a CYP isoform and substrate dependent manner. The study objectives were to identify POR protein variants in greyhounds and determine their effect on coexpressed CYP2B11 and CYP2D15 enzyme function. Gene sequencing identified two missense variants (Glu315Gln and Asp570Glu) forming four alleles, POR-H1 (reference), POR-H2 (570Glu), POR-H3 (315Gln, 570Glu) and POR-H4 (315Gln). Out of 68 dog breeds surveyed, POR-H2 was widely distributed across multiple breeds, while POR-H3 was largely restricted to greyhounds and Scottish deerhounds (35% allele frequencies), and POR-H4 was rare. Three-dimensional protein structure modelling indicated significant effects of Glu315Gln (but not Asp570Glu) on protein flexibility through loss of a salt bridge between Glu315 and Arg519. Recombinant POR-H1 (reference) and each POR variant (H2-H4) were expressed alone or with CYP2B11 or CYP2D15 in insect cells. No substantial effects on POR protein expression or enzyme activity (cytochrome c reduction) were observed for any POR variant (versus POR-H1) when expressed alone or with CYP2B11 or CYP2D15. Furthermore, there were no effects on CYP2B11 or CYP2D15 protein expression, or on CYP2D15 enzyme kinetics by any POR variant (versus POR-H1). However, Vmax values for 7-benzyloxyresorufin, propofol and bupropion oxidation by CYP2B11 were significantly reduced by coexpression with POR-H3 (by 34–37%) and POR-H4 (by 65–72%) compared with POR-H1. Km values were unaffected. Our results indicate that the Glu315Gln mutation (common to POR-H3 and POR-H4) reduces CYP2B11 enzyme function without affecting at least one other major canine hepatic P450 (CYP2D15). Additional in vivo studies are warranted to confirm these findings.

Currently, we can label the certain cells by transducing specific genes, called reporter genes, and distinguish them from other cells. For example, fluorescent protein such as green fluorescence protein (GFP) is commonly used for cell labeling. However, fluorescent protein is difficult to observe in living animals. We can observe the reporter signals of the luciferin-luciferase system from the outside of living animals using in vivo imaging systems, although the resolution of this system is low. Therefore, in this study, we examined the reporter genes, which allowed the MRI-mediated observation of labeled cells in living animals. As a preliminary stage of animal study, we transduced some groups of plasmids that coded the protein that could take and store metal ions to the cell culture, added metal ions solutions, and measured their T1 or T2 relaxation values. Finally, we specified the best reporter gene combination for MRI, which was the combination of transferrin receptor, DMT1, and Ferritin-M6A for T1WI, and Ferritin-M6A for T2WI.

¿Cómo se mira un sueño?
Authors: Muriedas Díez Maria
Published: February 2024

Este texto se fundamenta en la experiencia del hacer, partiendo del proyecto que desde hace un tiempo estoy desarrollando en torno a la traducción a imágenes vídeo de una serie de sueños. A la vez que se proponen las traducciones de los sueños a texto como partituras o protocolos performativos, se evidencia, en un intento de búsqueda a priori alejado de simbolismos y significados ocultos, la imposibilidad de trasladar/registrar fielmente lo soñado tanto a palabras como a imagen en movimiento. En esta doble imposibilidad, el proceso de materialización en vídeo de estos enunciados mediante el dispositivo de registro y la puesta en escena, lo onírico choca con lo contingente, y de esta forma, se producen narrativas que pueden trasladarnos a sucesos cotidianos que conectan con nuestras vivencias o inquietudes personales. Esta metodología de choque, posibilita una investigación de análisis teórico y práctico que permite indagar en torno a conceptos como: lo real y lo ficcional, visibilidad e invisibilidad, la imagen y su representación, así como las narrativas abiertas o inconexas, y el papel que éstos ocupan en las formas del vídeo de exposición contemporáneo.
Reflexión teórico-práctica sobre la creación audiovisual participativa

Published: February 2024

Existe una forma de creación audiovisual participativa que se desarrolla en entornos educativos, comunitarios o artísticos, y que se distingue de los modelos de producción audiovisual más convencionales. En términos de procesos creativos, se establecen desde enfoques más horizontales, con una dimensión política, y suelen estar vinculados a proyectos que evolucionan según las contribuciones de las personas participantes. Estas narrativas colectivas, colaborativas y/o participativas se construyen mediante procesos de mediación y metodologías participativas. Este artículo tiene como objetivo crear un corpus discursivo en torno a las prácticas audiovisuales colaborativas y/o participativas para seguir ahondando en su práctica y reflexión teórica. Para ello, se plantea confrontar las referencias teóricas con el estudio de caso de un proyecto real de video participativo desarrollado en 2022 en una residencia de mayores de Bermeo (Bizkaia) bajo el nombre de «Remake».
Pertinencia y actualidad de las prácticas y estéticas del vídeo arte doméstico en España
Authors: Trigueros Mori Carlos
Published: February 2024

El video arte doméstico hace referencia a una serie de trabajos artísticos que utilizan tanto la tecnología no profesional del video como medio de expresión, así como sus modos de hacer, con temáticas variadas que van desde la vida cotidiana hasta la recepción de los impactos mediáticos. Durante la segunda década del siglo XXI en este país su desarrollo se ha decantado hacia registrar y documentar tanto la vida cotidiana, así como narrativas desnormalizadas a partir de material de archivo familiar o personal, de manera crítica y creativa. Así mismo, se han acentuado las capacidades de esta subcategoría del vídeo arte hacia la veracidad de lo mostrado y la cercanía con el espectador, a diferencia de otros usos que propugnan la distancia y la artificiosidad. En esta revisión se indagará, consustancialmente, en la ruptura generacional que ha producido la pandemia en las prácticas de vídeo arte doméstico.
La Iglesia católica y el sindicalismo vertical: entre la colaboración y la crítica, 1951-1959
Authors: Bernal García Francisco
Published: February 2024

Durante la década de 1950, en la España franquista, el sindicalismo vertical fue objeto de controversia desde una perspectiva católica. Los dirigentes de los sindicatos trataron de legitimarse defendiendo su adecuación a la doctrina social de la Iglesia. Algunos sectores eclesiásticos avalaron esta pretensión, pero otros la rechazaron. Tanto los defensores de la catolicidad del verticalismo como los detractores de esta idea coincidían en que era necesario poner fin al sistema de reglamentaciones laborales elaboradas por el Ministerio de Trabajo y permitir autonomía a empresarios y trabajadores en la negociación de las condiciones de trabajo. Debido a ello, cuando en 1958 fue promulgada la Ley de Convenios Colectivos, los dirigentes verticalistas pensaron que finalizarían las críticas católicas a su modelo. Sin embargo, esta Ley, lejos de acabar con la controversia, provocó una escalada en la misma, con nuevas críticas, dirigidas ahora a la insuficiente representatividad de los sindicatos.

Las mariposas han sido representadas como parte del simbolismo mesoamericano prehispánico y posthispánico. Algunos investigadores han estudiado esas representaciones desde la clasificación taxonómica. El objetivo de esta investigación fue sistematizar la diversidad taxonómica de lepidópteros mesoamericanos proporcionada por fuentes históricas. Para ello, i) se realizó una revisión sistematizada de las especies de mariposas reportadas en la literatura, ii) se incluyó una revisión de la nomenclatura actual de las especies, iii) se sugirió un cambio/corrección de la identificación de un taxón. En general, se obtuvo un listado taxonómico de doce lepidópteros en estado adulto y nueve lepidópteros en estado larvario con base en las fuentes de información prehispánicas y posthispánicas. Se sugirió un cambio/corrección de Acentrocneme kallari Scudder, 1875 (Aegiale hesperiaris Walker, 1856) a Scyphophorus acupunctatus Gyllenhal, 1838, basado en conocimientos biológicos, lingüísticos y etnológicos vinculados a la especie propuesta. Este estudio da cuenta del nacimiento de la lepidopterología en la región neotropical.
Children’s and young people’s cognizance of physical-symbolic reality: The production and acquisition of spatial knowledge

Published: February 2024

In this article, we address the central topic of the call for papers, childhood educates space, from the perspective of children’s and young people’s spatial knowledge. We argue that both childhood and youth educate as much as are educated by space. To shed light on this dynamic and complex interaction, we focus on the arenas and agencies at play within the production and acquisition of spatial knowledge. The term arena refers to the spatial conditions that delineate an area of activity related to the production and acquisition of spatial knowledge, and agency denotes the crucial means, agents, and tools that are instrumental in and buttress such area of activity. To render operative the analysis, we draw on two driving themes: (i) the gradual development of a comprehensive conception of space and (ii) its accompanying (and traversing) learning processes. Moreover, to substantiate the assertion that education between childhood and youth and space is mutually constitutive, we present a selection of findings from a qualitative meta-analysis conducted to reconstruct the evolution of young people’s spatial knowledge from the 1970s onwards. All in all, we claim that the process of production and acquisition of spatial knowledge forms the basis of, on the one hand, the keenness and depth of the perception that children and young people have of the physical world and, on the other, the ways they subjectively and symbolically characterize it.
Espacios de transición en la arquitectura escolar pública colombiana. 2000-2020
Authors: Arango Silvia
Published: February 2024

En las primeras dos décadas del siglo XXI, la arquitectura escolar se ha consolidado como una expresión distintiva de la identidad arquitectónica en Colombia. La construcción de cientos de edificios educativos, que se destacan por su calidad espacial, ha implicado un esfuerzo significativo en el contexto de América Latina. El artículo examina inicialmente los antecedentes políticos y arquitectónicos de este fenómeno, especialmente en lo atinente a la llamada “arquitectura del lugar”, para explicar la importancia de la arquitectura escolar pública como representativa de este trabajo colectivo a nivel nacional, regional y municipal. En el diseño de la arquitectura escolar colombiana reciente, se analizan los espacios de transición como lugares privilegiados de interacción y porque se considera que en ellos reside la calidad arquitectónica. Por eso se identifican dos escalas: la general y la cercana. En la escala general, se precisan cinco sistemas compositivos principales: bloques, claustros, metáforas urbanas, tramas y collares, concebidos como pautas para clasificar las variaciones que dependen de los distintos contextos geográficos, culturales e históricos. En la escala cercana, se observan los materiales, detalles y espacios de los espacios intermedios, o de transición que resultan fundamentales en el diseño de las escuelas tanto en su relación social con la comunidad que le sirve de contexto, como en las relaciones interpersonales al interior de ellas. Las distintas estrategias que disuelven los límites, facilitan y multiplican estas interacciones tan importantes en el contexto colombiano contemporáneo.
Balancing Green and Gold: The Link Between Sustainability Reporting and Corporate Reputation in Malaysia

Published: February 2024

Corporate reputation has gained significant attention within academic circles and emerged as a critical concern in practical business contexts. However, prior studies on this topic have been somewhat fragmented, creating fertile ground for exploring new research avenues, particularly in assessing reputation. Sustainability reporting, corporate governance, and company attributes have been associated with enhancing corporate reputation. Nevertheless, there remains a dearth of research exploring these variables' impact on the novel reputation measurement proxy, especially in emerging economies like Malaysia. Therefore, this study investigates the intricate relationship between sustainability reporting and corporate reputation using the new proxy of reputation in the context of Malaysia, a dynamic and rapidly growing economy. Balancing the 'Green' aspects of sustainability with the 'Gold' aspects of company performance and reputation is a pivotal concern for organizations in the region. The results showed sustainability reporting significantly impacts corporate reputation to sustain a harmonious equilibrium characterized by "Green" and "Gold" elements. The findings encourage Malaysian PLCs to navigate this duality successfully and can reap long-term benefits regarding reputation, stakeholder trust, and sustainable profitability.

The Role of Innovative Work Behavior, Teamwork Climate, and Information Sharing in Enhancing the Innovative Performance of Energy Companies
Authors: Jankelová Nadežda , Mišún Juraj , Joniaková Zuzana
Published: February 2024

This paper aims to test a positive relationship between managers' support for innovative work behavior (IWB) and innovative performance (IP) of energy companies (EC), mediated by information sharing (IS) and teamwork climate (TWC).

The sample consisted of 235 EC in Slovakia. Data analysis was carried out using the PLS-SEM method.

The results show that support for IWB can be considered as a predictor of IP, as managerial support for employees' innovative behavior (IB) has a positive effect on firms' IP. However, its effect may be enhanced by the interaction of other factors. Transparency of communication and support for teamwork (TW) have positive effects on overall IP. Sharing information with employees and fostering a climate of TW become important tools for innovative management. Neither the manager's seniority nor the manager's age has a significant effect on the relationship examined.

Keywords: innovative performance of energy companies; innovative work behavior; information sharing; teamwork climate; management of energy companies
Well-being and Sustainable Development: An Exploratory Approach from a Marketing Perspective
Authors: Lopez Diana Vanegas
Published: February 2024

Since the publishing of the Brundtland Report (1987), which formally introduced, defined, and approached the concept of sustainable development creating the framework for its implementation, the concern for preserving what we have for future generations has steadily and significantly increased. Consumers, citizens, businesses, and public entities have acknowledged the need to ensure an appropriate economic, social, and environmental development capable of providing a sustainable common future. Strategies, plans, and programs have been drafted, projects and activities have been conducted, and a huge amount of practical experience, as well as a rich dedicated scientific

literature, has been accumulated.

The tremendous effort that has led to the SDGs, Net Zero, and Green Deal has been designed and implemented from a societal perspective under a vision underlining the prevalence of the common or greater over the individual good, the last one being the consequence of the overall development of the society. What if the perspective changes by focusing on the individuals and individual good considering the greater or common good as an aggregate result achieved by the entire society by adding the state of well-being experienced by each and every individual? Viewing the subject from a marketing angle, the aggregated well-being of individuals should generate an overall sustainable development of society. The article presents and discusses the findings of exploratory research assessing the connections between individual well-being and sustainable development

Public Voices in the Environmental Decision-Making in Georgia
Authors: Chichua Marina , Matchavariani Lia
Published: February 2024

The article presents the results of the scientific research and gives the ways to solve the problems dedicated to PP (public participation) in the process of EDM (environmental decision-making) in Georgia. Several obstacles were found, by studying the environmental non-governmental organizations (NGOs) in Georgia. All necessary information was collected through interviews and questionnaires. The study discusses the existing legislation on this issue and aims to find answers to these obstacles. Four hypotheses were developed - transparency in the decision-making process promotes successful public participation, effective cooperation with one another is a better way for NGOs to participate in the environmental decision-making process, Georgian NGO’s successful participation in the process of DM (decision-making) was related to the development of an environmental legal system, self-financing helps the Environmental NGOs in Georgia to improve their financial status and increase their flexibility in the EDM  process. The Soviet regime caused the nonexistence of PP approaches in EDM. Currently, many international and trans-boundary projects are taking place and will be completed shortly in Georgia. The participation of the public, especially non-governmental organizations is a key point and crucial element in decision making as most of these developments entail additional environmental problems and to prevent damage to the environment and foster sustainable development when such projects are completed. The research gives key provisions that require improvement to increase the effectiveness of PP in EDM process.
