Published: August 2023

Optical biometers are routinely used to measure intraocular distances in ophthalmic applications such as cataract surgery planning or myopia monitoring. However, due to their high cost and reduced transportability, access to them for screening and surgical planning is still limited in low-resource and remote settings. To increase patients’ access to optical biometry we propose a novel low-cost frequency-domain optical delay line (FD-ODL) based on an inexpensive stepper motor spinning a tilted mirror, for integration into a time-domain (TD) biometer, amenable to a compact footprint. In the proposed FD-ODL, the axial scan range and the A-scan rate are decoupled from one another, as the former only depends on the spinning mirror tilt angle, while the A-scan rate only depends on the motor shaft rotational speed. We characterized the scanning performance and specifications for two spinning mirror tilt angles, and compared them to those of the standard, more expensive FD ODL implementation, employing a galvanometric scanner for group delay generation. A prototype of the low-cost FD-ODL with a 1.5 deg tilt angle, resulting in an axial scan range of 6.61 mm and an A-scan rate of 10 Hz was experimentally implemented and integrated in a dual sample beam optical low-coherence reflectometry (OLCR) setup with a detour unit to replicate the measurement window around the anterior segment and the retina. The intraocular distances of a model eye were measured with the proposed low-cost biometer and found in good agreement with those acquired by a custom swept-source optical coherence tomography (SS-OCT) system, and two commercial biometers, validating our novel design.
Deep Optics Preconditioner for Modulation-free Pyramid Wavefront Sensing

Published: August 2023

The Pyramid Wavefront Sensor (PWFS) can provide with the sensitivity needed for demanding adaptive optics applications, such as imaging exoplanets using the future extremely large telescopes of over 30 meters of diameter. However, its exquisite sensitivity has a limited linear range of operation. Linearity, or dynamic range, can only be extended through the use of beam modulation, at the expense of sacrificing sensitivity and the addition of modulation optics in the sensor’s optical path. Inspired by artificial intelligence techniques, this work proposes to train an optical layer–comprised of a passive diffractive element placed at a conjugated Fourier plane where the tip of the pyramid lies–to boost the linear response of the pyramid sensor without the need for the cumbersome modulation. We develop an End-2-End simulation to train the single-layer optical preconditioner, while assuming a traditional least-square modal phase estimation. Simulation results with a large range of turbulence conditions show a noticeable improvement in the aberration estimation performance equivalent to over 3λ/D of modulation when using the optically preconditioned Deep PWFS (DPWFS). Experimental results validate the advantages of using the designed optical layer, where the DPWFS can pair the performance of a traditional PWFS with 2λ/D of modulation. Designing and adding an optical preconditioner to the PWFS is just the tip of the iceberg, since the same methodology herein developed can be used for the design of a new generation of wavefront sensors that can better fit the demands of sophisticated adaptive optics applications such as space and underwater optical communications, and imaging through scattering media.

Published: August 2023

The opportunistic pathogenPseudomonas aeruginosacauses antibiotic–recalcitrant pneumonia by forming biofilms in the respiratory tract. Despite extensive in vitro experimentation, howP.aeruginosaforms biofilms at the airway mucosa is unresolved. To investigate the process of biofilm formation in realistic conditions, we developed AirGels: 3D, optically accessible tissue–engineered human lung models that emulate the airway mucosal environment. AirGels recapitulate important factors that mediate host–pathogen interactions including mucus secretion, flow and air–liquid interface (ALI), while accommodating high–resolution live microscopy. With AirGels, we investigated the contributions of mucus toP.aeruginosabiofilm biogenesis in in vivo–like conditions. We found thatP.aeruginosaforms mucus–associated biofilms within hours by contracting luminal mucus early during colonization. Mucus contractions facilitate aggregation, thereby nucleating biofilms. We show thatP.aeruginosaactively contracts mucus using retractile filaments called type IV pili. Our results therefore suggest that, while protecting epithelia, mucus constitutes a breeding ground for biofilms.
Deep learning for COVID-19 topic modelling via Twitter: Alpha, Delta and Omicron
Authors: Lande Janhavi , Pillay Arti , Chandra Rohitash
Published: August 2023

Topic modelling with innovative deep learning methods has gained interest for a wide range of applications that includes COVID-19. It can provide, psychological, social and cultural insights for understanding human behaviour in extreme events such as the COVID-19 pandemic. In this paper, we use prominent deep learning-based language models for COVID-19 topic modelling taking into account data from the emergence (Alpha) to the Omicron variant in India. Our results show that the topics extracted for the subsequent waves had certain overlapping themes such as governance, vaccination, and pandemic management while novel issues aroused in political, social and economic situations during the COVID-19 pandemic. We also find a strong correlation between the major topics with news media prevalent during the respective time period. Hence, our framework has the potential to capture major issues arising during different phases of the COVID-19 pandemic which can be extended to other countries and regions.
Dynamics of international Trade: A 30-year analysis of key exporting nations
Authors: Yazawa Nobuo
Published: August 2023

This article aims to analyze the evolution of trading networks, emphasizing aspects of centrality and reciprocity among the major exporting nations, specifically, the U.S., China, India, Japan, and South Korea, from 1992 to 2020. The study problem we address is how these network structures have shifted over time, and what the implications of these changes are for international economic relations and policy. We further consider the impact of major global events on these trade networks and how they have shaped the evolution of these networks. We utilized three distinct methods. First, we examined time-series trade data during the study period and quantified network reciprocity through the sum of squared trade imbalances across different product categories. Second, we visualized these trade networks using arrows, with their sizes being proportional to the trade value between each pair of countries; significant trade relationships were indicated by arrows with a standard deviation value of 55 or above. Finally, we introduced a new cluster analysis methodology for studying the evolution of network structures over time. This method utilized an 80-dimensional vector representation of the annual networks, divided into four categories, and the resulting structures were visualized as dendrograms using R software. The network structure has become more reciprocal for most product categories, and the center of the network has shifted from the U.S. to China for all product categories, except for consumer goods and raw materials. The study also highlights the significant impact of global events and crises such as 9/11 attacks on the international trade network structure. Our findings inform several policy recommendations. These include encouraging balanced trade for economic stability and improved international relations, realigning trade focus in response to the shift in trade network center, and developing resilience policies that account for the substantial impact of global events on trade networks.

Authors: Xu Zhangmeng , Zhang Furong , Qiu Guorong , Shi Yushan , Yu Duoduo , Dai Guogang , Zhu Tianmin
Published: August 2023

Background

Observational studies suggest physical activity (PA) enhances intelligence, while sedentary behavior (SB) poses a risk. However, causality remains unclear.

Methods

We extracted genetic instruments from large genome-wide association studies summary data and employed an inverse-variance weighted (IVW) approach within a random-effects model as the primary method of Mendelian randomization (MR) analysis to estimate the overall effect of various physical activity statuses on intelligence. To assess IVW stability and MR sensitivity, we also utilized supplementary methods including weighted median, MR-Egger, and MR-PRESSO. Furthermore, multivariable MR analysis was conducted to examine the independent effects of each physical activity trait on intelligence.

Results

The MR primary results indicated that LST was negatively associated with intelligence (β = -0.133, 95%CI: -0.177 to -0.090, p = 1.34×10–9), while SBW (β = 0.261, 95% CI: 0.059 to 0.463, p = 0.011) may have a positive effect on intelligence; however, MVPA and SC did not show significant effects on intelligence. Inverse causality analyses demonstrated intelligence significantly influenced all physical activity states.

Conclusions

Our study highlights a bidirectional causal relationship between physical activity states and intelligence.
Novel anti-PTEN C2 domain monoclonal antibodies to analyse the expression and function of PTEN isoform variants
Authors: Torices Leire , Nunes-Xavier Caroline E. , López José I. , Pulido Rafael
Published: August 2023

PTEN is a major tumor suppressor gene frequently mutated in human tumors, and germline PTEN gene mutations are the molecular diagnostic of PTEN Hamartoma Tumor Syndrome (PHTS), a heterogeneous disorder that manifests with multiple hamartomas, cancer predisposition, and neurodevelopmental alterations. A diversity of translational and splicing PTEN isoforms exist, as well as PTEN C-terminal truncated variants generated by disease-associated nonsense mutations. However, most of the available anti-PTEN monoclonal antibodies (mAb) recognize epitopes at the PTEN C-terminal tail, which may introduce a bias in the analysis of the expression of PTEN isoforms and variants. We here describe the generation and precise characterization of anti-PTEN mAb recognizing the PTEN C2-domain, and their use to monitor the expression and function of PTEN isoforms and PTEN missense and nonsense mutations associated to disease. These anti-PTEN C2 domain mAb are suitable to study the pathogenicity of PTEN C-terminal truncations that retain stability and function but have lost the PTEN C-terminal epitopes. The use of well-defined anti-PTEN mAb recognizing distinct PTEN regions, as the ones here described, will help to understand the deleterious effects of specific PTEN mutations in human disease.
Why is it difficult for children and adults to follow a person’s eye gaze in polynomial social relationships with compound audio-visual stimuli: An eye-tracking study
Authors: Oka Misaki , Omori Mikimasa
Published: August 2023

Acquiring triadic social interactions could facilitate language and communication skills in early infancy. However, studies have rarely investigated polynomial relationships, defined as relationships among the self, two or more people, and objects. During the development from a child to an adult, the responsiveness to a preferred stimulus modality changes from visual to auditory dominance. Nevertheless, how people observe compound visual stimuli in polynomial social relationships and why it is difficult to ignore auditory cues remain unclear. Moreover, there is a need to identify differences between children’s and adults’ observing latencies in the time to the first fixation when detecting a stimulus. This study examined whether participants (24 adults and 19 children) demonstrated similar gaze patterns under triadic and polyadic conditions. The participants observed a target visual stimulus looked at by a face stimulus while we presented spoken names, either congruent or incongruent with the target visual stimulus. The results indicated that when the number of people in social relationships increased, children and adults decreased fixations on the target face and the stimulus and showed a shorter mean fixation duration on the face. Moreover, children had longer latencies and more fixation errors for the target stimulus, which might reflect children’s difficulties in communicating with others. We expect that understanding children’s communication transition from triadic to polynomial social relationships with audio-visual stimulus congruencies would facilitate understanding language development and social communication patterns.
Non-inactivating voltage-activated K+ conductances can increase photoreceptor signaling bandwidth beyond the bandwidth set by phototransduction
Authors: Frolov Roman V.
Published: August 2023

Evolution produced a large variety of rhabdomeric photoreceptors in the compound eyes of insects. To study effects of morphological and electrophysiological differences on signal generation and modulation, we developed models of the cockroach and blow fly photoreceptors. The cockroach model included wide microvilli, large membrane capacitance and two voltage-activated K+conductances. The blow fly model included narrow microvilli, small capacitance and two sustained voltage-activated K+conductances. Our analysis indicated that membrane of even the narrowest microvilli of up to 3 μm long can be measured fully from the soma. Attenuation of microvillar quantum bump (QB)-like signals at the recording site in the soma increased with the signal amplitude in the microvillus, due to the decreasing driving force. However, conductance of the normal-sized QBs can be detected in the soma with minimal attenuation. Next, we investigated how interactions between the sustained voltage-activated K+and light-induced conductances can shape the frequency response. The models were depolarized by either a current injection or light-induced current (LIC) and probed with inward currents kinetically approximating dark- or light-adapted QBs. By analyzing the resulting voltage impulse responses (IR), we found that: (1) sustained K+conductance can shorten IRs, expanding the signaling bandwidth beyond that set by phototransduction; (2) voltage-dependencies of changes in IR durations have minima within the physiological voltage response range, depending on the activation kinetics of K+conductance, the presence or absence of sustained LIC, and the kinetics of the probing current stimulus; and (3) sustained LIC lowers gain of IRs and can exert dissimilar effects on their durations. The first two findings were supported by experiments. It is argued that improvement of membrane response bandwidth by parametric interactions between passive, ligand-gated and voltage-dependent components of the membrane circuit can be a general feature of excitable cells that respond with graded voltage signals.
The effects of a comparatively higher dose of 1000 mg/kg/d of oral L- or D-arginine on the L-arginine metabolic pathways in male Sprague-Dawley rats
Authors: Kim Dain (Raina) , Martin Sarah , Desai Kaushik
Published: August 2023

Oral L-arginine supplements are popular mainly for their nitric oxide mediated vasodilation, but their physiological impact is not fully known. L-arginine is a substrate of several enzymes including arginase, nitric oxide synthase, arginine decarboxylase, and arginine: glycine amidinotransferase (AGAT). We have published a study on the physiological impact of oral L- and D-arginine at 500 mg/kg/day for 4 wks in male Sprague-Dawley rats. We investigated the effects of oral L-arginine and D-arginine at a higher dose of 1000 mg/kg/d for a longer treatment duration of 16 wks in 9-week-old male Sprague-Dawley rats. We measured the expression and activity of L-arginine metabolizing enzymes, and levels of their metabolites in the plasma and various organs. L-arginine did not affect the levels of L-arginine and L-lysine in the plasma and various organs. L-arginine decreased arginase protein expression in the upper small intestine, and arginase activity in the plasma. It also decreased AGAT protein expression in the liver, and creatinine levels in the urine. L-arginine altered arginine decarboxylase protein expression in the upper small intestine and liver, with increased total polyamines plasma levels. Endothelial nitric oxide synthase protein was increased with D-arginine, the presumed metabolically inert isomer, but not L-arginine. In conclusion, oral L-arginine and D-arginine at a higher dose and longer treatment duration significantly altered various enzymes and metabolites in the arginine metabolic pathways, which differed from alterations produced by a lower dose shorter duration treatment published earlier. Further studies with differing doses and duration would allow for a better understanding of oral L-arginine uses, and evidence based safe and effective dose range and duration.
Reframing the contribution of pelagic Sargassum epiphytic N2 fixation
Authors: Johnson Claire , Dubbs Lindsay L. , Piehler Michael
Published: August 2023

Though nitrogen fixation by epiphytic diazotrophs on pelagic Sargassum has been recognized for decades, it has been assumed to contribute insignificantly to the overall marine nitrogen budget. This six-year study reframes this concept through long-term measurements of Sargassum community nitrogen fixation rates, and by extrapolating mass-specific rates to a theoretical square meter portion of Sargassum mat allowing for comparison of these rates to those of other marine and coastal diazotrophs. On 24 occasions from 2015 to 2021, rates of nitrogen fixation were measured using whole fronds of Sargassum collected from the western edge of the Gulf Stream off Cape Hatteras, North Carolina. Across all dates, mass-specific rates ranged from 0 to 37.77 μmol N g-1 h-1 with a mean of 4.156 μmol N g-1 h-1. Extrapolating using a mat-specific density of Sargassum, these rates scale to a range of 0 to 30,916 μmol N m-2 d-1 and a mean of 3,697 μmol N m-2 d-1. Quantifying this community’s rates of nitrogen fixation over several years captured the sometimes-extreme variability in rates, characteristic of marine diazotrophs, which has not been reported in the literature to date. When these measurements are considered alongside estimates of the density of pelagic Sargassum, rates of nitrogen fixation by Sargassum’s epiphytic diazotrophs rival that of their coastal macrophyte and planktonic counterparts. Given Sargassum’s wide and expanding geographic range, the results of this study suggest this community may contribute reactive nitrogen on a meaningful, basin-wide scale, which merits further study.
Camp Cinema and the Queer Experience
Authors: Lamb Gabrielle
Published: August 2023

Camp is a queer sensibility which has recently begun to enter the mainstream. By viewing a case study of several key camp films of the twentieth and early twenty-first century, it is possible to chronicle its radicalism, and its gradual co-optation by the straight gaze. Camp, while at times reductive, has served to mirror and affirm the vibrancy of the queer experience, making an understanding of its roots essential.

Authors:   Crisis and Emergency Management: Theory and Praxis, Moon Sun-Hee
Published: August 2023

This study aims to evaluate the effect of a metaverse-based emergency nursing education program (MEEP) using V-story on nursing students. The MEEP included a five-hour orientation session, team-based case analysis, and role-play scenario writing and demonstration. In September and October 2021, the MEEP was used on 72 third-year nursing students from one college who had been simply divided into a control group (n = 38) or an intervention group (n = 34). Results indicated no significant difference in clinical competency between the two groups (t = 1.82, p = .073), but communication and nursing processes, which are sub-factors of clinical performance, significantly improved in the intervention group (t = 2.93, p = .005; t = 2.25, p = .027). No significant difference in problem-solving efficacy was found (t = −0.60, p = .549), but the intervention group reported significantly higher learning satisfaction (t = 2.48, p = .016). The study suggests that nursing education programs utilizing the metaverse should be developed on various topics.
Effects of Safety Management Perceived in Local Festivals on Sustainability: Focusing on Concert for Attracting Busan World Fair 2030
Authors:   Crisis and Emergency Management: Theory and Praxis, Kwon Seol A
Published: August 2023

The local festival is regarded as one of the important factors which may have economic, commercial, environmental, socio-cultural, psychological, and political effects on residents and also have effects on their social resilience and social capital strength. The purpose of this study is to analyze 'what effect do participants' perceptions have on the safety management provided to the festival?'. The findings show that the safety management perceived by participants who participated in the BTS 'Yet To Come' in BUSAN, a concert for attracting the Busan World Fair 2030 has a statistically significant effect on the sustainability of the festival, while the provision of safety information harms it, indicating that the higher the demand for providing information, the higher the need and the expectation for the safety management service. It would be necessary to specifically make safety management plans at the planning stage, to successfully attract local festivals, to implement transparent safety management policies and provide information in advance, to encourage the acceptance of such policies, and by increasing participants' reliability for safety.

Intrahepatic cholestasis as a paraneoplastic manifestation was first described by Dr. Maurice H. Stauffer in 1961. This paraneoplastic manifestation was primarily associated with renal cell carcinoma characterized by abnormal liver enzymes without hepatic metastasis. Stauffer syndrome is classified into 2 types: classical and jaundice variants. Indeed, the jaundice variant is extremely rare and only described in 13 published cases. We report a case of intrahepatic cholestasis associated with a type 1 papillary renal cell carcinoma with complete resolution after surgical treatment.

Introduction / Objectives: Gambling and gaming disorder are usually comorbid addictive behaviours in which alexithymia and emotional regulation have been proved to be of relevance. The present study aimed to analyse the relationship between those variables and their differences depending on the presence or absence of gambling and gaming behaviours. Method: The sample consisted of 1,219 people between 12 and 20 years of age (M = 15.55, SD = 2.07; 51.8% females). Results: The results showed significant differences between players and non-players in gambling disorder, alexithymia and emotional regulation. The findings also indicated that there were differences in alexithymia, emotional regulation, negative affect, gambling disorder and gaming disorder among the different profiles of video game players. The comparison of participants with gaming disorder, gambling disorder, both, or neither of them, showed differences in alexithymia, emotional regulation, negative affect, gambling disorder and gaming disorder. Furthermore, correlations between gambling disorder and age, gaming disorder, negative affect, alexithymia and emotional regulation were found. Similarly, gaming disorder was associated with gambling disorder, negative affect, alexithymia, emotional regulation and age. Conclusions: The hierarchical regression analyses demonstrated the predictive role of alexithymia and age in gambling disorder as well as the predictive role of age, sex and negative affect in gaming disorder.

Introducción: El estado de ánimo y la autoeficacia presentan estrecha relación con el rendimiento deportivo. En atletismo, contar con un control exhaustivo del entrenamiento físico y mental supone asentar las bases del máximo rendimiento, siendo el salto vertical un excelente elemento de control. Sin embargo, su relación con los aspectos psicológicos durante los entrenamientos se ha divulgado poco en la literatura. Este artículo tiene como objetivo analizar la relación entre el perfil de estado de ánimo y la autoeficacia durante saltos verticales en deportistas juveniles de la preselección nacional cubana de atletismo. Método: Se evaluó el estado de ánimo y la autoeficacia antes de ejecutar un salto con contramovimiento (CMJ), presentándose el valor de 40 cm como elemento de máximo rendimiento en atletas de élite. Resultados: Se encontró correlación significativa entre el factor ansiedad del POMS y variables del CMJ. Además, se encontró correlación negativa entre la autoeficacia y la ansiedad, aunque no significativa (p > .05). Conclusiones: Los deportistas con un estado de ánimo de puntuación media de ansiedad, aunque no sobreelevada (puntaje 2 sobre 4) antes de la ejecución de saltos verticales, obtuvieron mejores resultados de CMJ, consiguiendo un mayor rendimiento tanto en la altura de salto, como en la velocidad, fuerza y potencia del salto. Sin embargo, no se hallaron correlaciones significativas entre la autoeficacia y el estado de ánimo, ni con variables de salto.

The problem of optimal assignment of autonomous vehicles in production-logistics system
Authors: Volhonskaya Elizaveta E.
Published: August 2023

The problem of optimal assignment of autonomous vehicles to ongoing production processes is considered. Virtual testing for predictive maintenance involves the creation of digital twins based on simulation models. The solution of the assignment problem described in the article is the basis for building simulation models on Petri nets to analyze the dynamics of the production- logistics system. The structure of the agro-industrial system of grain harvesting by a complex of combines using autonomous vehicles based on KAMAZ vehicles is considered. Many characteristics of the production-logistics system have been determined: field areas and productivity, productivity of combines, carrying capacity and speed of vehicles, etc. The problem of minimizing operating costs for a complex of vehicles for a given distribution of combines over fields with grain crops has been formulated. The problem relates to integer linear programming with Boolean variables. The difference in the formulation of this problem lies in the formation of a number of restrictions that take into account the main parameters of the production-logistics system. An example of optimizing the distribution of autonomous vehicles for a given number of fields of harvesters processing them is considered. The resulting solution allows you to determine the set of vehicles ready for operation, as well as form a reserve of vehicles to reduce downtime. The solution of the proposed problem can be used as the basis for the structure of the simulation model as part of the digital twin of the production and logistics system. Also, the technique can be used in the current planning of real work of combines and vehicles.
Ambient temperature impact on the parameters of the electrical circuit of sensing element in cluster eddy current sensor of metal chips in the lubrication systems of gas turbine engines

Published: August 2023

The detection of the wear particles in the engines lubrication systems is one of the most effective ways to assess the state of the bearing assemblies of machines and mechanisms. The most promising existing systems for online monitoring of wear particles are based on the eddy current methods for monitored parameters conversion. The reason is that such systems have the ability not only to determine the particle size, but also to recognize its magnetic properties, which makes it possible (under certain conditions) to localize the place of the defect development. At the same time, it is known that the ambient temperature changes in the monitored zone are one of the main external factors that have a significant impact on the informative parameters of eddy current converters. This is of particular importance for debris monitoring systems in high-power plants lubrication systems (e.g. gas turbine engine), where the oil temperature can vary widely (-50...+160 C). The temperature impact on the parameters of the electrical circuit of sensing element in the cluster single-coil eddy current sensor of metal chips, which is a part of the debris continuous monitoring system prototype for high-thrust aviation gas turbine engine, is studied in the article. A typical design of the single-coil sensing element is considered. The study results of the temperature effect on the sensing element inductance, as well as on the parameters of the current lead that connects the sensing element to the matching transformer and to the measuring circuit are presented. Methods for reducing the impact of temperature changes in the monitored area on the parameters of the electrical circuit of the sensing element are proposed, too.

Published: August 2023

The pervasiveness of celebrity figures in contemporary media and the effect they have on the minds of the public made investigating their discourse and exhibiting the way they think a worthy topic to study closely. Celebrities, as a social group, use language as a means of inspiration, encouragement, and empowerment. In this regard, they become exemplary and inspirational to the public by conveying their opinion, attitude, ideas, and knowledge. It is worth saying, most celebrities are simultaneously influential, especially entertainers like sports stars. Their discourse is usually imbued with and drenched in feelings, qualities, morals, and values that attract people to follow them, share characteristics with them and watch them. Accordingly, the researchers of the current study selected three American athlete celebrities' speeches to analyze and investigate the type of language used and the kind of ideology imbued within the speeches. Van Dijk’s model (1995a, 2016) of the socio-cognitive approach, mainly the discourse-cognition-society paradigm, is applied to analyze the speeches. The main aim is to show how discourse, social and cognitive structures are used to convey ideologies and what types of ideologies are instilled in the (selected) athlete celebrities’ speeches. After conducting the analysis, the study ends with the conclusion that some profile athletes are key influencers as spokespersons in society at large and they mainly depict themselves in a positive bright way that assists in spreading their mindsets and ideologies.

Authors: Muhammed Ahmed A.
Published: August 2023

The paper examines different types of paradoxical connections in Sarah Ruhl’s Dead Man’s Cell Phone with respect to contemporary characteristics of American theatre. It is so clear that the play has a smooth transformation or connection between paradoxical states or situations. The transformation happens due to spatial, and temporal conditions, and different humankind values. The play is full of different types of connections due to social ties, contradictive life situations, death and life, the whole and the parts, the spatial and the temporal transformation, truth and lies, happiness and misfortune, fancy and facts, and humanity with technology. The study is qualitative depending on the study of the cases within the play that are contradicting each other, yet they serve in deepening the meaning and the understanding of the cases. The paradoxical issues to be studied in a comparative way, these comparative situations serve higher thematic issues in a philosophical dimension in very carefully woven relations between the characters and situational environment as well. The common sense that the play made is to accept the philosophy of black and white as positive paradoxical relation, that the black helps to see the pure white and vice versa. Common unanswered questions are to be presented in a rhetorical and philosophical manner; targeting these questions is the way of being closer to a bunch of truths about the complicated fabric relationships which link the characters all together.

One of the significant transformations in the Kurdistan Region of Iraq (KRI) is the implementation of the Bologna process. This alteration of the traditional system to the Bologna process system has also impacted the assessment schemes. More weight has been given to formative assessment that can help improve students’ grades and ease success in the courses. Nonetheless, the final exam still carries most of the grades. Therefore, setting appropriate questions that can meet all the cognition levels represented in Bloom’s taxonomy assists in raising students’ cognition to higher levels rather than only assessing bookish knowledge that is located on the baseline of Bloom’s taxonomy. To this intent, the present study endeavored to identify if instructors at colleges of Nursing and Science adhere to the various dimensions of Bloom’s taxonomy that are central to the Bologna process. More importantly, the association of each of the demographic variables to the level of the final examination questions was also examined. The study employed a quantitative method to tackle the topic. Totally, a sample of 75 final examination papers was collected from instructors, including 524 individual questions. The findings revealed that most of the examination papers revolved around low-order thinking questions and the association of the rate of success to the level of the questions was highly statistically significant.

A internacionalização da educação superior tem se alterado ao longo do tempo, a partir da indução de programas e fomentos governamentais, e as universidades, respondendo a essas demandas, têm buscado desenvolver ações de internacionalização que abarquem toda a comunidade universitária. Este artigo tem como objetivo analisar as estratégias de internacionalização contidas nos planos e políticas das instituições de educação superior brasileiras que participam do Programa Institucional de Internacionalização – Programa CAPES PrInt. Trata-se de um estudo de cunho qualitativo, realizado a partir de uma pesquisa documental e o tratamento de dados foi realizado com base na análise de conteúdo. A partir da análise dos dados, cinco áreas prioritárias foram observadas: Ensino; Políticas Linguísticas; Pesquisa; Extensão, Cultura e Arte; e Gestão. Não há predominância de um modelo de internacionalização entre as estratégias desenvolvidas pelas universidades no Brasil, mas o convívio entre as diferentes formas de internacionalização, caracterizando a busca por uma identidade que reflita as características do ensino superior brasileiro. Os resultados revelam a direção que as instituições brasileiras estão adotando rumo à institucionalização da internacionalização e sua contribuição para a consolidação do campo científico sobre a internacionalização da educação euperior ao preencher uma lacuna, ainda existente, na literatura brasileira.

Authors: López Martínez Juan
Published: August 2023

En el presente estudio se realiza un análisis de las obligaciones informativas de los intermediarios fiscales que han colaborado en el diseño de mecanismos transfronterizos de planificación fiscal agresiva, de las relaciones que se establecen entre ellos y los obligados tributarios interesados, y del alcance, y de sus contradicciones, de la dispensa de la obligación de informar como consecuencia del secreto profesional. En él se pone de manifiesto la insuficiencia armonizadora de la dac6 y la deficiente regulación de las normas de trasposición del Reino de España.
La incidencia del trabajo a distancia en la determinación de la residencia habitual de las personas físicas en el territorio de las CCAA como punto de conexión en los tributos cedidos y concertados
Authors: Rovira Ferrer Irene
Published: August 2023

Tras la generalización del trabajo a distancia a causa de la pandemia de Covid-19, la ausencia de barreras físicas y geográficas que caracteriza su desarrollo ha dado lugar a un nuevo escenario tanto a nivel interno como internacional. En este contexto, el principal objetivo del presente trabajo es analizar su impacto en uno de los aspectos de mayor importancia para el buen funcionamiento del sistema tributario español, como son los puntos de conexión que determinan la procedencia de los tributos cedidos y de los tributos concertados. En concreto, se determinará y analizará su incidencia respecto a los puntos de conexión basados en la residencia habitual de las personas físicas en el territorio de una Comunidad Autónoma, clarificando los aspectos más importantes que deberían tenerse en cuenta para su adecuada determinación en cada uno de los criterios que se establecen al respecto. Asimismo, con base en su estudio, se aportarán algunas propuestas para mejorar la regulación de cada uno de dichos criterios con carácter general.
El sustituto del contribuyente: revisión dogmática de un concepto que arraigó en la imposición sobre la renta (comentario a la STS 523/2023, de 17 de febrero de 2023)
Authors: Simón-Yarza María Eugenia
Published: August 2023

El Tribunal Supremo se pronuncia en casación sobre la legitimación de la Administración tributaria para dirigirse de manera directa al contribuyente obviando la figura del sustituto del contribuyente. La caracterización del contribuyente y del sustituto del contribuyente que realiza el TS coincide con las definiciones de la Ley General Tributaria. Las dificultades que plantea la asunción por parte del TS de unas declaraciones legales que son meramente formularias se desvanecen a la luz de los conceptos normativos de ambas figuras subjetivas.
El ejercicio de la deducción por las cuotas soportadas de IVA como derecho del contribuyente. Análisis de las SSTS 23 de febrero y de 25 de abril de 2023
Authors: González Aparicio Marta
Published: August 2023

Las Sentencias del Tribunal Supremo de 23 de febrero y 25 de abril de 2023 configuran el ejercicio de la deducción de las cuotas soportadas de IVA como un derecho del contribuyente, lo que supone que resulte admisible la solicitud de rectificación de una autoliquidación complementaria presentada fuera del plazo de declaración. El Tribunal se opone así la interpretación aplicada por la Administración, que consideraba tal ejercicio como una opción tributaria del artículo 119.3 de la LGT y consolida su jurisprudencia, iniciada en el año 2021, en relación con la conceptualización de las opciones tributarias. Los criterios ofrecidos por el Tribunal Supremo favorecen la seguridad jurídica, poniendo coto a la interpretación expansiva que la Administración viene sosteniendo de este concepto. Asimismo, la consideración de estos criterios por los órganos de la Administración se plantea como una oportunidad para reducir la litigiosidad vinculada a esta cuestión.
