En marzo de 2020, el gobierno argentino decretó el Aislamiento Social Preventivo y Obligatorio (ASPO) para enfrentar el avance del COVID-19. En este contexto, el sistema educativo en su conjunto debió desplegar estrategias didácticas innovadoras para dar continuidad a los aprendizajes. En el Programa de Lectura y Escritura Académicas de la Universidad de Flores (Buenos Aires, Argentina), en particular, se introdujeron innovaciones al dispositivo didáctico (Moyano, 2007), sin dejar de lado el marco teórico que adopta regularmente el programa (Martin, 1999; Martin y Rose, 2007, 2008; Moyano 2007, 2011). En este trabajo se expone y analiza la experiencia docente llevada a cabo. La enseñanza se implementó en cuatro grupos, correspondientes a cuatro asignaturas de la carrera de Derecho. Los resultados obtenidos se evaluaron teniendo en cuenta el proceso evolutivo de cada grupo a lo largo de un semestre, comparando sus desempeños en escritura en dos momentos de construcción de un texto, correspondiente al género académico o profesional seleccionado para cada asignatura: la primera construcción y la versión final. Sobre la base de los resultados, se argumenta que las estrategias didácticas implementadas permitieron sostener la enseñanza, evitaron la pérdida de matrícula y acompañaron el proceso de trabajo de forma satisfactoria, en tanto las producciones escritas lograron altos niveles de desempeño en términos de su calificación final.

Management of the adverse effects of cancer immunotherapy with a focus on the respiratory and nervous systems
Authors: Park Song Ee
Published: March 2023

Background: The incidence of adverse toxic reactions to immunotherapy using immune checkpoint inhibitors is 2-10% in the respiratory system and 3.9% to 12% in the neurologic system. The severity of adverse effects increases when combined immunotherapeutic agents are administered.Current Concepts: In cases of high-grade toxicity, it is important to discontinue immunotherapy immediately. In cases of grade 3 to 4 toxicity, immunosuppressive corticosteroid therapy is the first-line treatment. Short-term steroid treatment does not affect anti-tumor efficacy. It is thus necessary to use steroids for an appropriate period then carefully taper the steroid dose to prevent recurrence. If no improvement is achieved within 48-72 hours after the administration of steroids, it is essential to initiate multidisciplinary treatment involving related departments and add immunosuppressive drugs. If the patient is administrated immunotherapy again, it may be necessary to permanently discontinue the immunotherapy depending on the toxicity grade that first occurred.Discussion and Conclusion: The primary goals for effective management of immunotherapy-related adverse events are early recognition of symptoms and immediate treatment.
How do we trade off benefits and harms of anticancer drugs for advanced cancer patients?
Authors: Kim Do Yeun
Published: March 2023

Background: The overall survival rate of advanced cancer patients has improved thanks to the development of modern medical treatments, particularly new and innovative chemotherapeutic agents such as targeted therapies and immune checkpoint inhibitors.Current Concepts: Chemotherapy is administered in neoadjuvant, adjuvant, and palliative settings, and its ultimate goal is to improve overall survival. Chemotherapy has several proven and valuable clinical benefits, but also many side effects that cannot be ignored, especially in patients with poor European Cancer Oncology Group performance status. Therefore, we must carefully weigh and trade off the benefits and harms from many chemotherapy agents. In fact, it can be difficult to determine whether advanced cancer patients really benefit from chemotherapy, which is why a number of value measurement tools such as the American Society Clinical Oncology-Value Framework and the European Society for Medical Oncology-Magnitude of Clinical Benefit Scale have been developed.Discussion and Conclusion: We need to include individual cancer patients in decision-making processes and use appropriate shared decision-making to decide whether or not to administer chemotherapy. Furthermore, we should perform rational trade-offs in consideration of limited health resources.
Managing the adverse effects of cytotoxic chemotherapy at the level of primary healthcare
Authors: Hong Ji Hyung
Published: March 2023

Background: Despite the increased incidence of cancer, more effective cancer drugs are being developed and cancer patient survival expectancy has been prolonged. Here, we discuss the contribution of primary healthcare clinics to managing the side effects of cytotoxic chemotherapy and provide a compilation of what is currently being used in this field.Current Concepts: Loperamide is recommended for active use when diarrhea occurs. In severe cases, octreotide can help control diarrhea by reducing small bowel fluid secretion. Mouthwash mixed with salt and sodium bicarbonate is helpful for controlling mucositis, and transdermal fentanyl patches can be used for severe pain. Limited evidence suggests that pilocarpine may be helpful for xerostomia. Neurokinin-1 receptor antagonists, serotonin receptor antagonists, glucocorticoids, metoclopramide, and olanzapine are used for nausea and vomiting. Opioid-related constipation can be relieved without counteracting the analgesic effect of opioids via peripherally acting μ-opioid receptor antagonists. Granulocyte colony-stimulating factor is recommended to treat neutropenic fever. In cases with neutropenia but no fever, the decision to use it should be based on the patient’s condition. Minoxidil can be used for hair loss, and scalp cooling can also be considered, but its practical applications are limited. Topical steroid ointments are used to treat hand-foot syndrome. Selective serotonin re uptake inhibitors are recommended for depression in cancer patients because they have little interaction with other drugs and are well tolerated.Discussion and Conclusion: Due to an increased cancer patient management burden and limited medical resources, primary healthcare practitioners should know these management strategies for cancer patients receiving cytotoxic chemotherapy.
Clinical forms and diagnosis of tuberculosis
Authors: Cesur Salih
Published: March 2023

Tuberculosis is an infectious disease whose diagnosis dates back to very early ages, which still maintains its importance in the world and in our country, can be treated and prevented with preventive (prophylactic) treatment. It is one of the leading causes of death in HIV/AIDS positive patients. Tuberculosis can be seen in two ways, mainly lung tuberculosis and extra-pulmonary tuberculosis. Tuberculosis forms other than lung and laryngeal tuberculosis are not contagious. Today, the HIV epidemic and international migration are the main causes of the increase in the number of tuberculosis cases. In this collected work, lung and non-pulmonary forms of tuberculosis, clinical diagnosis, and current developments in diagnosis are summarized.

Abstract. At present, a strong latitudinal sea surface temperature (SST) gradient of ~16 °C exists across the Southern Ocean, maintained by the Antarctic Circumpolar Current (ACC) and a set of complex frontal systems. Together with the Antarctic ice masses, this system has formed one of the most important global climate regulators. The timing of the onset of the ACC-system, its development towards modern-day strength, and the consequences for e.g., the latitudinal SST gradient around the southern Atlantic Ocean, are still uncertain. Here we present new TEX86-biomarker records, calibrated to SST, from two sites located east of Drake Passage (southern South Atlantic) to assist in better understanding two critical time intervals of prominent climate transitions during the Cenozoic: The Late Eocene–Early Oligocene (ODP Site 696) and Middle–Late Miocene (IODP Site U1536) transitions. Our results overall show rather temperate conditions (20–11 °C) during the Late Eocene to Early Oligocene interval, with a weaker latitudinal SST gradient (~8 °C) across the Atlantic sector of the Southern Ocean compared to present day (~16 °C). We ascribe the regional similarity in SSTs across the Late Eocene–Early Oligocene South Atlantic to a persistent, strong Subpolar Gyre circulation, connecting all sites, which can only exist in absence of a strong throughflow across the Drake Passage. Surprisingly, the southern South Atlantic records show comparable SSTs (~12–14 °C) during both the Earliest Oligocene Oxygen Isotope Step (EOIS, ~33.65 Ma) and the Miocene Climate Optimum (MCO, ~16.5 Ma). Apparently, maximum Oligocene Antarctic ice volume could coexist with warm ice-proximal surface ocean conditions, while at similar ocean temperatures, the Middle Miocene Antarctic ice sheet was strongly reduced. Southern South Atlantic SSTs cooled to ~5 °C at the onset of the Middle Miocene Climate Transition (MMCT, 14 Ma), making it the coldest oceanic region recorded around Antarctica and the likely main location for deep water formation. The already cold southern South Atlantic conditions at MMCT meant it experienced little cooling during the latter part of the Miocene, which contrasts the profound cooling due to northward expansion of the Southern Ocean frontal systems in the lower latitudes and other sectors of the Southern Ocean.
Using statistical models to depict the response of multi-time scales drought to forest cover change across climate zones
Authors: Li Yan , Rust Henning W. , Huang Bo
Published: March 2023

Abstract. The interaction between forest and climate exhibits regional differences due to a variety of biophysical mechanisms. Observational and modelling studies have investigated the impacts of forested and non-forested areas on a single climate variable, but the influences of forest cover change on a combination of temperature and precipitation (e.g., drought) have not been explored owing to the complex relationship between drought conditions and forests. In this study, we use the historical forest and climate datasets to explore the changes in forest fraction and drought from 1992–2018. A set of linear models and an analysis of variance approach are utilized to investigate the effect of various factors on droughts across different time scales and climate zones. Our findings reveal that precipitation is the dominant factor leading to drought in the equatorial, temperate, and snow regions, while temperature controls drought in the arid region. The impact of forest cover on droughts varies under different precipitation and temperature quantiles. Precipitation modulates forest cover's impact on long-term drought in arid and snow regions, while temperature modulates forest cover's impact on both short- and long-term drought in the arid region as well as only on long-term drought in temperate and snow regions. Forest cover can also modulate the impacts of precipitation and temperature on drought. High forest cover leads to a combined effect of precipitation and temperature on long-term drought in equatorial, arid and snow regions, while precipitation is the only dominant factor in low forest cover conditions. In contrast, low forest cover triggers a strong combined effect of precipitation and temperature on drought in the temperate region. Our findings improve the understanding of the interaction between land cover change and the climate system and further assist decision-makers to modulate land management strategies in different regions in light of climate change mitigation and adaptation.
Characterizing 4 decades of accelerated glacial mass loss in the west Nyainqentanglha Range of the Tibetan Plateau

Published: March 2023

Abstract. Glacier retreat is altering the water regime of the Tibetan Plateau (TP) as
the region's climate changes, but there remain substantial gaps in our
knowledge of recent glacier loss in this region due to the difficulty of
making direct high-mountain observations, and this limits our ability to
predict the future of this important water resource. Here, we assessed 44 years of glacier area and volume changes in the major west Nyainqentanglha Range (WNR) that supplies meltwater to the densely populated Lhasa River basin and Nam Co, the second largest endorheic lake on the TP. Between the two periods 1976–2000 and 2000–2020, we found that the glacier areal retreat rate more than doubled (from -0.54±0.21 % a−1 to -1.17±0.30 % a−1), and surface lowering also accelerated (from -0.26±0.09 to -0.37±0.15 m w.e a−1) with particularly intense melting after 2014. This acceleration is similar in both timing and magnitude to that observed for Himalayan glaciers farther south. Besides, the areal retreat rate and mass loss rate of most glaciers in the WNR were not synchronized. To understand the sensitivity of WNR glaciers to climate forcing, we examined the effects of topography, debris cover and the presence of proglacial lakes on our observed changes. We found consistently faster areal retreat but slower thinning rates on steeper slopes and an inconsistent relationship with aspect. We concluded that our observed spatial and temporal patterns of glacier change were dominated by observed local variations in temperature and precipitation, the melt-reducing role of supraglacial debris, and the increasing influence of ice-marginal lakes on glacier ablation.
Sensitivity analysis of a built environment exposed to the synthetic monophasic viscous debris flow impacts with 3-D numerical simulations
Authors: Huang Xun , Zhang Zhijian , Xiang Guoping
Published: March 2023

Abstract. The characteristics of exposed built environments have a
significant effect on debris flow impacts on buildings, but knowledge about
their interactions is still limited. This paper presents a sensitivity
analysis on the peak impact forces on a whole building resulting from the
built environment parameters, including the orientation, opening scale of
the target building, and azimuthal angle and distance of surrounding
buildings. The impact forces were obtained from the monophasic viscous
debris flow with a synthetic and simplified hydrograph using the FLOW-3D
model, a computational fluid dynamics approach, verified through the
physical modeling results. The results show that the surrounding buildings'
properties have significant roles in determining the peak impact forces. A
shielding effect or canalization effect, which reduces or increases impact
forces, respectively, can be produced by changing the azimuth angle. A
deflection wall for building protection is recommended according to the
shielding effect. A narrowed flow path, determined by both the azimuth angle and distance, has a significant effect on the variation in impact forces. In
addition, it is concluded that a splitting wedge should be designed
following a criterion of avoiding the highest flow depth – the maximum
approaching angle – appearing near the longest wall element. The protruding parts caused by changing the building's orientation contribute to increasing
impact loads within a shielding area. A limited opening scale effect is
observed on the whole building if there is sufficient time for material
intrusion. The insights gained contribute to a better understanding of
building vulnerability indicators and local migration design against debris
flow hazard.
A corrected finite-difference scheme for the flexure equation with abrupt changes in coefficient
Authors: Hindle David , Besson Olivier
Published: March 2023

Abstract. The fourth-order differential equation describing elastic flexure of the lithosphere is one of the cornerstones of geodynamics that is key to understanding topography, gravity, glacial isostatic rebound, foreland basin evolution, and a host of other phenomena. Despite being fully formulated in the 1940s, a number of significant issues concerning the basic equation have remained overlooked to this day. We first explain the different fundamental forms the equation can take and their difference in meaning and solution procedures. We then show how numerical solutions to flexure problems as they are currently formulated are in general potentially unreliable in an unpredictable manner for cases in which the coefficient of rigidity varies in space due to variations of the elastic thickness parameter. This is due to fundamental issues related to the numerical discretisation scheme employed. We demonstrate an alternative discretisation that is stable and accurate across the broadest conceivable range of conditions and variations of elastic thickness, and we show how such a scheme can simulate conditions up to and including a completely broken lithosphere more usually modelled as an end-loaded, single, continuous plate. Importantly, our scheme will allow breaks in plate interiors, allowing, for instance, the creation of separate blocks of lithosphere which can also share the support of loads. The scheme we use has been known for many years but remains rarely applied or discussed. We show that it is generally the most suitable finite-difference discretisation of fourth-order, elliptic equations of the kind describing many phenomena in elasticity, including the problem of bending of elastic beams. We compare the earlier discretisation scheme to the new one in one-dimensional form and also give the two-dimensional discretisation based on the new scheme. We also describe a general issue concerning the numerical stability of any second-order finite-difference discretisation of a fourth-order differential equation like that describing flexure wherein contrasting magnitudes of coefficients of different summed terms lead to round-off problems, which in turn destroy matrix positivity. We explain the use of 128 bit floating-point storage for variables to mitigate this issue.
Platform yaw drift in upwind floating wind turbines with single-point-mooring system and its mitigation by individual pitch control
Authors: Sandua-Fernández Iñaki , Vittori Felipe , Martín-San-Román Raquel , Eguinoa Irene , Azcona-Armendáriz José
Published: March 2023

Abstract. This work demonstrates the feasibility of an individual pitch control strategy based on nacelle yaw misalignment measurements to mitigate the platform yaw drift in upwind floating offshore wind turbines, which is caused by the vertical moment produced by the rotor. This moment acts on the platform yaw degree of freedom, being of great importance in systems that have low yaw stiffness. Among them, single-point-mooring platforms are one of the most important ones. During recent years, several floating wind turbine concepts with single-point-mooring systems have been proposed, which can theoretically dispense with the yaw mechanism due to their ability to rotate and align with environmental conditions (weather-vaning). However, in this paper it is proven that the vertical moment overcomes the orienting ability, causing the yaw drift. With the intention of reducing the induced yaw response of a single-point-mooring floating wind turbine, an individual pitch control strategy based on nacelle yaw misalignment is applied, which introduces a counteracting moment. The control strategy is validated by numerical simulations using the 5 MW National Renewable Energy Laboratory (NREL) wind turbine mounted on a single-point-mooring version of the DeepCwind OC4 floating platform to demonstrate that it can mitigate the yaw drift and therefore maintain the alignment of the wind turbine rotor with the wind.
Force-Velocity Profiling in Club-Based Field Hockey Players: Analyzing the Relationships between Mechanical Characteristics, Sex, and Positional Demands
Authors: Hicks Dylan S. , Drummond Claire , Williams Kym J. , Tillaar Roland van den
Published: March 2023

The purpose of this study was to investigate differences between sex and positional demands in club-based field hockey players by analyzing vertical force-velocity characteristics. Thirty-three club-based field hockey athletes (16 males - age: 24.8 ± 7.3yrs, body mass: 76.8 ± 8.2kg, height: 1.79 ± 0.05m; 17 females - age: 22.3 ± 4.2yrs, body mass: 65.2 ± 7.6kg, height: 1.66 ± 0.05m) were classified into two key positional groups (attacker or defender) based on dominant field position during gameplay. Force-velocity (F-v) profiles were established by performing countermovement jumps (CMJ) using a three-point loading protocol ranging from body mass (i.e., zero external mass, 0%) to loads corresponding to 25% and 50% of their own body mass. Across all loads, between-trial reliability of F-v and CMJ variables was determined by intraclass correlation coefficients (ICCs) and coefficient of variation (CV) and deemed to be acceptable (ICC: 0.87-0.95, CV% 2.8-8.2). Analysis by sex identified male athletes had significantly greater differences in all F-v variables (12.81-40.58%, p ≤ 0.001, ES = 1.10-3.19), a more enhanced F-v profile (i.e., greater theoretical maximal force, velocity, and power values), plus overall stronger correlations between relative maximal power (PMAX) and jump height (r = 0.67, p ≤ 0.06) when compared to female athletes (-0.71≤ r ≥ 0.60, p = 0.08). Male attackers demonstrated a more ‘velocity-oriented’ F-v profile compared to defenders due to significant mean differences in theoretical maximal velocity (v0) (6.64%, p ≤ 0.05, ES: 1.11), however differences in absolute and relative theoretical force (F0) (15.43%, p ≤ 0.01, ES = 1.39) led to female attackers displaying a more ‘force-oriented’ profile in comparison to defenders. The observed mechanical differences identify the underpinning characteristics of position specific expression of PMAX should be reflected in training programmes. Therefore, our findings suggest F-v profiling is acceptable to differentiate between sex and positional demands in club-based field hockey players. Furthermore, it is recommended field hockey players explore a range of loads and exercises across the F-v continuum through on-field and gym-based field hockey strength and conditioning practices to account for sex and positional mechanical differences.
Génesis de la noción de trabajo de duelo en Glas de Jacques Derrida
Authors: Campos Salvaterra Valeria
Published: March 2023

Abordamos la primera configuración de la tesis del trabajo de duelo (travail du deuil) en la filosofía de Jacques Derrida, desarrollada en el texto Glas de 1974, en directa relación con la filosofía de Hegel. Dicha tesis es central para la deconstrucción y alude a un esquema especulativo que puede relacionarse tanto con las tempranas propuestas sobre la auto-afección como proceso de constitución del sí mismo, como también con la operación de consumación idealizante que está a la base de las teorías sobre el origen del sentido en la tradición filosófica occidental. En ambos casos, se trata de configurar una tesis deconstructiva sobre la relación con la alteridad en general, cuestión que constituye para Derrida el núcleo del problema epistemológico de la historicidad del sentido. Sostenemos que la configuración del trabajo de duelo es el resultado de una serie de decisiones teóricas en relación con la filosofía de Hegel, que implican considerar el lugar de la vida y la muerte en sistema, así como también una relación incorporativa entre una y otra, mediada por la dinámica de la Aufhebung.

This article investigated brine cheeses' nutritional value and safety by adding vegetable additives (dry powder of white cabbage and coriander). Brynza brine cheese was used as the basis for the recipe. By the chemical composition of the cheese with vegetable, additives has a significantly higher protein content (26.27 g/100g), while the fat content is lower (14.98 g/100g). There is a high content of amino acids and fatty acids (PUFA 6%, MUFA 24%). During prolonged storage of brine cheese, water activity aw decreases in control from 0.997 to 0.990, mass fraction of moisture increases from 60% to 62.5%, in the brine cheese with vegetable additives aw from 0.998 to 0.991, mass fraction of moisture from 61.1% to 63.7%.The use of vegetable additives in the formulation of cheeses does not affect the deterioration of microbiological parameters compared to the control sample. As a result of experimental studies, the shelf life of brine cheese with vegetable additives is 8-10 days.

The effectiveness of plastic packaging in protecting food is quite appreciable, but its non-biodegradable characteristic raises concerns about environmental impacts. This has drawn attention to the development of alternative materials for food packaging from bio-based polymers. Chitosan, a polysaccharide with biodegradable, biocompatible, and non-toxic properties, is widely used in the formulation of food films. The objective of this work was to create a biodegradable and sustainable chitosan-based film whose active and intelligent action is obtained from red cabbage anthocyanins and the addition of propolis. The edible film’s thickness and total polyphenol content were 61.0 ±0.1μm and 20.08 ±0.5 mgAG g-1, respectively. The content of phenolic compounds and the biodegradation showed significant results (p <0.05), besides the good thermal stability to 200 °C and transparency. The proposed formulation developed an edible, biodegradable, and active (antioxidant) film with interesting heat-sealing resistance, moisture barrier and gas transfer, which contributes to increasing food shelf life.

Rationale: Clinical reasoning (CR) skills of physical therapy (PT) residents may be limited by a lack of clinical experience, and the complexity of neurologic and elderly patients requires individualized approaches for prescribing walking assistive devices (ADs). Script concordance tests (SCTs), which are case-based assessments that present information that the test taker must examine before answering, can measure the growth in CR. The purpose was to validate a SCT designed to measure CR growth in residents for walking AD prescription.
Methods: Using a prospective cohort design, a panel of 20 experienced practicing clinicians reviewed the test content and provided the correct answers. Neurologic and geriatric residencies were identified from the American Board of Physical Therapy Residencies and Fellowships database. Residency directors were informed of the study, and 27 of them provided access to their residents. Residents gave assent in month 1 and were followed through month 6. The SCT and instructions were emailed at both time points. In total, 27 month-1 tests and 20 month-6 tests were returned. Fleiss kappa was used to evaluate the consistency of the clinician panel’s and the residents’ responses at both time periods. Mean scores for the panel and the residents at months 1 and 6 were calculated. Testing for differences between the clinician panel and the residents at months 1 and 6 was assessed using a Mann-Whitney U test, and testing for differences between the residents at the same time points was assessed using a Wilcoxon signed rank test.
Results: Demographics of the clinical panel and residents are presented. Internal consistency was moderate, and chance agreement was fair in both groups. Mean test scores were 34.8 (4.3), 34.5 (4.1), and 36.3 (3.9) points for the panel, and residents at months 1 and 6, respectively. Concordance of choices on the SCT between the clinician panel and residents was similar at month 1 and grew more concordant by month 6.
Conclusion: The SCT did not differentiate between the practicing clinicians’ and residents’ CR skills to prescribe ADs. Further research comparing the CR of PT residents to PT clinicians in early practice should be undertaken since the residents’ responses were consistent with the practicing clinicians. The unique test construction or the clinician panel, whose members were not required to be board certified, may have introduced error.
ANALYTICAL INVESTIGATION OF WAX MIGRATION IN RUBBER COMPOUNDS

Migration of wax in a model sidewall formulation was studied by characterization of the compound surface over time. Vulcanizates were prepared with different wax types at equal loadings, including neat paraffinic wax, a 1:1 blend of paraffinic and microcrystalline wax, and neat microcrystalline wax. The amount of wax on the surface was measured by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and was governed by the type of wax included in the formulation. The ATR-FTIR findings were corroborated by the performance of each vulcanizate under ozone aging at static conditions. Despite the distinct differences observed in the quantity of surface wax, gas chromatography (GC) analysis of the surface waxes indicated that the composition of the migrated wax was remarkably similar regardless of the wax type used. Additionally, the degree of similarity between the composition of the constituent wax and wax recovered from the surface film correlated directly with film thickness. These results provide observable evidence in support of the theory that wax migration is governed by the competing effects of solubility and mobility of alkane chains within the rubber matrix and demonstrate a framework for future investigations of rubber oxidation mitigation. The combination of ATR-FTIR and GC, in particular, permits identification of specific wax fractions migrating out of the rubber matrix and quantification of the corresponding film thickness over an extended period of time, resulting in a robust characterization of the compound surface and thorough understanding of optimal wax compositions for various implementations under isothermal, application-specific conditions.

El presente artículo busca abrir el diálogo sobre una dimensión poco explorada de la obra y la teoría de Oscar Correas, su íntimo vínculo con la teoría posestructuralista a través de la influencia dentro de su perspectiva marxista, de la crítica a la metafísica que retoma de Oscar del Barco, quien a su vez se vio profundamente influenciado por autores como Deleuze y Derrida. Aspiramos, a través de un análisis de los conceptos de ideología e inversión en la obra de Correas, a mostrar algunas de las líneas de investigación que se abren como posibilidades en el contexto de este diálogo.

Los ingresos públicos tras la pandemia. Residuos fiscales e inflación
Authors: García-Miralles Esteban , Martínez Pagés Jorge
Published: March 2023

Motivación

Tras la pandemia de COVID-19, el elevado dinamismo de los ingresos públicos en España ha redundado en un aumento de su peso como porcentaje del PIB de 3,7 puntos porcentuales (pp) desde 2019. Entender la naturaleza de esta evolución resulta fundamental a la hora de evaluar la política fiscal española.

Ideas principales

•El artículo descompone el crecimiento de los ingresos en cuatro factores explicativos: la actividad económica real, el avance de los precios, el efecto de las medidas fiscales y la parte no explicada o residuo.

•El efecto de los precios (inflación) ha ido ganando peso y, en 2022, explicaría algo más de la mitad del crecimiento observado de los ingresos, especialmente en el IVA y en el IRPF.

•Con todo, se estima que 2,6 pp de los 3,7 pp de aumento de la ratio de ingresos sobre PIB de los tres últimos años no podría explicarse por la actividad económica, los precios o las medidas fiscales aprobadas. En ausencia de una explicación sobre la naturaleza permanente o transitoria de este fenómeno, el principio de prudencia aconsejaría no considerar este incremento de los ingresos como permanente.
