Importance of Emotional Intelligence for the Leaders to Manage People and Business Effectively in Times of Crisis
Authors: K. Abirami , S. M. Jayasudha
Published: March 2023

Businesses have had financial and economic crises in the past, but none have compared to the COVID-19 pandemic, according to industry leaders. There is always a need for consistency, safety, and compassion in situations like COVID-19. Emotional intelligence has long been considered a crucial leadership skill. Now more than ever it is essential to navigate this crisis and establish a new normal. Consider emotional health as water in a glass that, in normal circumstances, might slowly evaporate and that leaders occasionally need to top off. Change, uncertainty, tension, and anxiety, however, behave like holes in the glass during a crisis, allowing water to pour out all over the place. There needs to be more top-down additions made in order to maintain emotional stability. Leadership plays an essential role in difficult situations to guide individuals or the group down the rocky path that lies ahead. Leaders must develop the traits that will enable them to efficiently manage their emotions and, in turn, assist others in managing theirs.
An Adaptable Approach to Fault Tolerance in Cloud Computing
Authors: Kumari Priti , Kaur Parmeet
Published: March 2023

Existing fault tolerance approaches in the cloud are broadly based on replication and checkpointing. Each of these approaches has its advantages and limitations. This paper presents an adaptable fault tolerance method for determining which of the two approaches will be appropriate for the successful execution of a task in the given cloud conditions. The proposed method classifies the failure risk of host machines available for task execution based on their failure history. Subsequently, fuzzy logic is used to determine the appropriate fault tolerance approach by considering a host's failure risk, user-defined task's priority, and level of resource redundancy. Setting a task's priority provides a user with control to solicit a desired fault tolerance level while the availability of resources reflects a cloud provider's capability to offer fault tolerance. Simulation experiments have verified that the proactive selection of a fault-tolerance method increases the number of tasks that complete successfully.
Enterprise Management Data Acquisition System Based on WoT
Authors: Yan Kun , Li Dongyan
Published: March 2023

With the rapid development of the WoT, acquisition requirements to the data grow with each passing day. However, the existing data acquisition systems usually use the upload mode. Uploading data not only takes a lot of time, but also requires staff to continuously monitor on duty. Aiming at the problem of enterprise management data acquisition, a WoT-based enterprise management data acquisition and analysis system is constructed. The system obtains multiple monitoring data through the data acquisition module and integrates these data through the processing module, which can solve the problems of traditional data acquisition systems. In order to effectively fuse data, based on canonical correlation analysis (CCA), the multiple order statistics correlation discrimination analysis algorithm is proposed as a fusion strategy. Experimental results show that the fusion strategy based on CCA can effectively integrate monitoring data and accurately identify different characters.
Effect of Electrical Poling on the Structural, Dielectric, and Photoluminescence Properties of Eu3+ Substituted Eco-Friendly Ferroelectric Material Na0.5Bi0.5TiO3
Authors: Mev Sumit Kumar , Sireesha Lavadiya , Raavi Sai Santosh Kumar , Asthana Saket
Published: March 2023

In this work, the effect of electric field on structural, photoluminescence, dielectric, and piezo/ferroelectric properties of 2.5 mole % Eu3+substituted sodium bismuth titanate (Na0.5Bi0.475Eu0.025TiO3 abbreviated as NBT-Eu) ferroelectric material has been investigated. Rietveld refinement on the X-ray diffraction patterns of poled and unpoled ceramics suggested lower monoclinic symmetry (Cc) with 93.64% as major phase fraction and higher orthorhombic symmetry (Pbnm) with 6.36% as minor phase fraction. For the poled composition, the monoclinic (Cc) phase fraction decreased to 83.53%, and the orthorhombic (Pbnm) phase fraction increased to 16.47%. Improved ferroelectric and piezoelectric characteristics in comparison to pure NBT were found in Eu3+ substituted NBT. Moreover, the substitution with Eu3+ enabled observation of photoluminescence (PL) emission in the visible region under an excitation wavelength of 532 nm for electrically poled and unpoled ceramics, thereby enabling additional functionality for this material along with ferroelectric and dielectric properties. Intensities of PL emissions were tuned by the application of electric poling of the ceramic, which generates the possibility of using these materials in optoelectronics device applications.

Published: March 2023

Today, biodegradable polymers are used to obtain various functional materials, including for the needs of agriculture. The article describes the current state of the production of polymeric materials, the problems of their operation, as well as the prospects for the creation of new polymeric biodegradable materials for agriculture. It is found that, depending on the method of obtaining a biopolymer-based material, its ability to diffuse water and water absorption is different – non-woven materials have higher performance than film materials. After seed germination, the thermophysical characteristics of the polylactide-based material change, the degree of crystallinity decreases by 7-10%, which indicates the destruction of the crystalline phase.
Durability of Asphalt Concrete with Mineral Fillers Made of Non-Carbonate Raw Materials
Authors: Kopylov V.E. , Burenina O.N.
Published: March 2023

The decisive influence on the corrosion resistance of asphalt concrete, and, consequently, on its durability is influenced by the presence of structural bonds at the interface between phases "crushed stone - binder". The weakening of these bonds leads to formation of various defects in roadway - cracks, potholes, etc. The article examines influence of mineral fillers made of non-carbonate raw materials on the durability of asphalt concrete. Analysis of group composition of bitumen made it possible to establish a mechanism for slowing down the aging rate of an organic binder when using porous mineral fillers made of natural zeolites and brown coals. It was found that asphalt concrete with natural zeolite and brown coal in their composition have low dependence of deformative properties on ambient temperature compared to asphalt concrete with traditional limestone mineral filler.

Authors: Novikov M.V.
Published: March 2023

The technique and results of experimental studies of creep deformations of compressed elements made of foam concrete at constant compressive stresses in the 0.15-0.75 range of Rb are presented. The nature of the relationship between stresses and the corresponding deformations, the degree of reversibility of creep deformations during unloading of samples and the tendency of concrete to aging have been established. From the standpoint of the hereditary theory of aging, analytical expressions have been selected to approximate the curves of specific creep deformations depending on the average density of foam concrete and the magnitude of compression stresses. The largest deviations of the specific creep deformations of foam concrete between theoretical and experimental values are 11.4%, and the standard deviations for the entire observation period are 2.0%

Published: March 2023

The use of Atomic Force Microscopy (AFM) to observe the microstructure of asphalt binder promises a better insight compared to other microscopy techniques. In this study, AFM was used to investigate the effect of nanosilica concentration and aging conditions on the microstructure of asphalt binders. Asphalt binder penetration grade of 60/70 was modified with nanosilica (NS) by varying its concentration ranging from 1% to 5% (with the increment of 1%). Nanosilica modified binder (NSMB) were aged using a pressure aging vessel (PAV). The microstructure of the NSMB before and after aging were characterized using tapping mode of the atomic force microscopy (AFM). The effect of nanosilica (NS) addition and PAV ageing on the phase distribution, size of ‘bee’ structure and surface roughness of the asphalt binder were investigated. Based on this study, it was found that the addition of NS into asphalt binder tended to increase the distribution of the catana phase, as well as increasing the size of the bee structure and surface roughness of the AFM image. Besides that, the after long-term ageing was applied, the number of the bee structure and distribution of catana and peri phase also increased. It can be concluded that the addition of NS and aging increased the overall surface stiffness of the bitumen and has made the material surface more solid-like.

Self-consolidating concrete mix (SCC) is the innovative construction material meeting strict and current requirements. Due to high flowability thereof and own weight it is able to flow within and around the formwork with no vibration.
The “Construction Materials” department at the Ufa State Petroleum Technological University together with experts from the “Reinforced Concrete and Masonry Structures” department at the Moscow National Research State University of Civil Engineering made a range of experiments for making compositions of the modern innovative concrete mix. Regional materials were taken as the original ones to be used for concrete compositions.
Fresh concrete consistency, flowability (by slump and cone flow diameter), concrete life time, delamination by amount of bleeding water, strength of tested samples at 4, 7, 28 days of standard curing, density of hardened samples were monitored during the experiments.
Under the laboratory results SCC recipes for В25, В30, В35, В40, В45 compressive strength grade were prepared. Laboratory SCC compositions by compressive strength for В25-В45 grade complied with the required technological characteristics.
Under practical application of SCC some peculiarities were identified in the technology of making and pouring thereof to be considered to prevent defects in cast-in-situ constructions.

development of these techniques follows the fast evolution of more powerful computer hardwares and softwares. Studies have been carried out to establish the usefulness of several quantitative techniques in solving typical geological/geotechnical problems using available exploration and production
drillhole data. Results derived from these studies show the techniques are suitable for use in orebody modelling and mine planning. Practical case studies are presented in the report. Following these studies, modelling of bulk material handling systems is used to control mineral or metal feed
fluctuations.
The explosibility of three canadian coal dusts
Authors: Mintz K J
Published: March 2023

Explosibility measurements on coal dusts from the Cape Breton Development Corporation's Lingan Mine, TransAlta's Highvale Mine and the Quintette Mine in B.C. have been carried out along with some tests on Pittsburgh Standard coal dust. The Quintette coal dust
would not explode in the classical Hartmann apparatus, but did explode in the new 20-L vessel using a more powerful ignition source. The minimum explosible concentrations of the Lingan, Highvale and Pittsburgh coal dusts were all about the same (40 - 45 mg/L), that of the Quintette was higher (140
mg/L). The difference may be attributed to the much greater mean particle size of the Quintette dust. The explosion pressures (in kPa) were: Highvale, 600, Pittsburgh, 520, Lingan, 510, and Quintette, 440. The minimum oxygen concentrations required for explosions were (in % oxygen): Highvale
10.4, Lingan 10.5, and Quintette 14. The minimum ignition temperatures of dust clouds were (in °C): Highvale 510, Lingan 600, Quintette 620 and Pittsburgh 620. Further work is required to reconcile limit values.

Insulin resistance (IR) develops in obese children because of low vitamin levels and increased pro-inflammatory cytokine levels.This study aimed to analyze the relation between vitamin D, insulin resistance, tumor necrosis factor-alpha and interleukin 6 (IL-6)levels at admission and after weight loss. This study included 84 obese and 28 healthy pubertal children. Patient group was dividedinto four: IR positive and negative; weight loss (WL) positive and negative. Baseline and follow-up (6th month) values of serum25-hydroxyvitamin D and other parameters were evaluated. The prevalence of serum vitamin D deficiency and insufficiency were3.6% and 21.4% in the control group, 15.2% and 10.9% and 7.9% and 15.8% in the obese insulin positive and negative group;respectively. There was no relationship between vitamin D and IRand IL-6 levels, whereas cytokine levels were lower in obesechildren. As WL increased, vitamin D level and IR improved. No significant difference was found between vitamin D levels of obeseand control subjects. In obese children with weight loss, an insignificant increase was observed in vitamin D, cytokines, quantitativeinsulin sensitivity check index values and an insignificant decrease was noted in homeostatic model assessment for IR value.Further longitudinal studies with larger patient series with greater WL are warranted.

The researched variables consisted of the percentage of crude fiber, crude protein and ekstract ether. Laboratory analysis data for each treatment obtained were tabulated in a table and analyzed using analysis of variance (ANOVA) with the F test at the 5% level and continued with Duncan's test if parameters were found to be significantly different between treatments (Steel and Torrie, 1990). The results showed that there was a significant difference (P<0.05) in the percentage of crude fiber and ekstract ether, while the percentage of crude protein content did not show a significant difference (P>0.05). 0 days, 7 days, 14 days and 21 days affected the percentage of crude fiber and ekstract ether but did not affect the percentage of crude protein of fermented dregs sago.
“… con tutte le qualità che lo innalzano e i difetti che l’affliggono…” – O Instituto Nacional de Música de Vincenzo Cernicchiaro
Authors: Vidal João Vicente , Draghi Giulio
Published: March 2023

Reconhecida como uma das mais importantes obras da historiografia musical brasileira, a Storia della musica nel Brasile: Dai tempi coloniali sino ai nostri giorni (1549-1925) de Vincenzo Cernicchiaro permanece ainda hoje insuficientemente conhecida e compreendida. Partindo de um recorte da obra focando a relação do autor com o Instituto Nacional de Música, criado em substituição ao antigo Imperial Conservatório em 1890, procura-se jogar luz sobre importantes debates e disputas estéticas que tiveram lugar no Rio de Janeiro na primeira fase da República. Acredita-se assim que as reverberações de Cernicchiaro de dois momentos críticos daquela instituição, a época de sua fundação e a época em que escreveu o livro, terminam por oferecer uma abertura privilegiada para o pensamento histórico do autor.
TRADITIONAL AND UPDATED EVALUATION OF THE RANGELAND SITE AND CONDITION IN THE SEMIARID SCRUB OF THE HIGH PLATEAU
Authors: Aguirre-Rivera Juan Rogelio , Negrete-Sánchez Luis Octavio , Castro-Rivera Rigoberto
Published: March 2023

In Mexico, the concepts of rangeland site and condition are not well known. For this reason, most of the rangelands of private ranches on the high plateau of San Luis Potosí and Zacatecas are undergoing a process of severe generalized deterioration. The purpose of this study was to survey and characterize multi-branched rangeland sites of three beef cattle ranches on the San Luis Potosí-Zacatecas High Plateau, as well as to assess their condition using a quantitative ecological method complemented by updated technological tools. The hypothesis proposed was that the site and condition of rangeland evaluated with the quantitative ecological method (used for grasslands and soil), complemented by updated technology, are also identifiable in multi-branched rangelands of this type of production units on the San Luis Potosí-Zacatecas High Plateau. Based on a Landsat satellite image, an unsupervised classification process was performed for the three ranches, which was then confirmed by field observations. A total of 11 sites were surveyed, three on each ranch (microphyll desert scrub, predominantly Bouteloua gracilis; microphyll desert scrub, with predominance of Sporobolus airoides; and an ecotone between microphyll desert scrub and rosetophile desert scrub) and two exclusive locations (crassicaule scrub and rosetophile desert scrub with predominance of Muhlenbergia villiflora). Rangeland condition was evaluated by measuring density and volume (volumetric biomass) of the main plant species, categorized by forage value, and the actual state of the soil surface was assessed in terms of bare soil and vegetation, litter, feces and rock cover. The data were ordered and classified with the DECORANA and TWINSPAN modules from the PC-ORD program. Site and condition evaluation under this approach was satisfactory for surveying the state of the rangelands of the three private cattle ranches studied on the San Luis Potosí-Zacatecas High Plateau.
Fragmentação da morfologia peri-urbana de Curitiba/PR
Authors: Dias de Almeida Proença Anderson
Published: March 2023

A expansão urbana morfologicamente dispersa e fragmentada está associada ao surgimento de problemáticas territoriais como o consumo exagerado de terras, água e energia, a má relação entre custo-benefício para implantação de infraestruturas urbanas, e o aumento das distâncias necessárias para a mobilidade cotidiana. Tal modelo de urbanização, em um contexto de elevada desigualdade socioeconômica como o brasileiro, tende a ser ainda mais agravados para as camadas mais pobres da população. A partir deste aparato conceitual, neste artigo objetivou-se analisar a expansão recente da Regional Tatuquara, localizada no extremo sul dos limites municipais de Curitiba, que constitui o principal vetor de expansão urbana da Região Metropolitana desde a década de 1990. Identificou-se o predomínio de uma morfologia urbana descontínua em relação ao tecido urbano central da metrópole, constituída majoritariamente por loteamentos horizontais e conjuntos habitacionais isolados que fomentam a fragmentação do espaço urbano. Conclui-se que este modelo de urbanização está vinculado à uma estratégia explicita de afastamento das áreas destinadas à habitação social por parte dos planos urbanos existentes.
O QUE HÁ EM UM NOME?
Authors: Perdigão Hêmille
Published: March 2023

Partindo do questionamento da personagem Julieta, da peça Romeu e Julieta, de William Shakespeare, sobre o que há em um nome, o presente trabalho propõe uma leitura dos romances Um Retrato do Artista quando Jovem e Ulysses, de James Joyce, discutindo os possíveis significados dos nomes dos personagens. Foi constatado que, em alguns momentos dos romances, há um equilíbrio entre nome e identidade, o qual é, em seguida, abalado. A conclusão foi que o romance Um Retrato do Artista quando Jovem  é uma obra na qual há uma falsa impressão, pelo protagonista Stephen Dedalus, de que nome e identidade se equilibram definitivamente, ao passo que, em Ulysses, o desequilíbrio entre identidade e nome é constatado, tendo destaque, nessa descoberta, as cenas em que há imagens de flores desabrochando e do litoral como metonímias dos processos identitários vividos pelos protagonistas Stephen Dedalus e Leopold Bloom.

O Ser Humano É uma Aventura: Por uma Antropopedagogia Contemporânea
Authors: Charlot Bernard
Published: March 2023

Como pensar uma pedagogia contemporânea, para além do debate entre pedagogias “tradicionais” e “novas”? Uma pedagogia que nos permite enfrentar os desafios do século XXI – ecológicos, tecnológicos, demográficos, e este desafio constituído pelo atual regresso de velhas formas de barbárie e pela emergência da ciberbarbárie. Historicamente, nunca o indivíduo foi tão livre e nunca o sujeito foi tão abandonado. Numa sociedade contemporânea que legitimou o desejo e multiplicou as redes de comunicação, como repensar essa relação dialética entre Desejo e Norma que está no centro de todos os discursos pedagógicos que herdamos, clássicos ou novos? Precisamos hoje de uma nova Utopia antropológica para escapar à lógica da competição generalizada que devora as nossas sociedades, incluindo as escolas, e recolocar o ser humano no centro da reflexão e das práticas pedagógicas. Não o ser humano como “natureza humana”, mas o ser humano como Aventura.
Chains Defects Detection in a Printed Circuit Board Image by the Plane Partition and Flood-filling of Traces

Published: March 2023

An approach to dividing the printed circuit board into parts to increase visibility of defects in a PCB image is considered. The approach is based on a piecewise linear approximation of a cumulative histogram. The last one is calculated for numbers of informative pixels placed in rows and columns of an image matrix. Informative pixels are those indicating contacts and C traces. The histogram demonstrates a distribution of informative pixels along the OX and OY axes. The beginning and ending points of linear lines are taken as coordinates of the divided parts of the PCB board. The flood-fill algorithm is used to color and separate the PCB chains components. The start pixels are taken from a set of informative pixels. To measure defect values, a mean intensity and gradient functions for the template and manufactured images are used. Distributed cumulative histograms are applied to PCB components to detect places and intensity of defects.

Object detection systems based on deep learning have been immensely successful incomplex object detection tasks images and have shown potential in a wide range of real-life applicationsincluding the COVID-19 pandemic. One of the key challenges in containing and mitigating the infectionamong the population is to ensure and enforce the proper use of face masks. The objective of this paperis to detect the proper use of facial masks among the urban population in a megacity. In this study, wetrained and validated a new dataset to detect images such as ‘with mask’, ‘without mask’, and ‘masknot in position’ using YOLOv5. The dataset is comprised of 6550 images with the three classes. Thedataset attained a commendable performance accuracy of 95% on mAP. This study can be implementedfor automated scanning for monitoring the proper use of face masks in different settings of public spaces.
A Literature Review on Developing Causes and Mitigation Strategies of Delay in Construction Projects: Gaps Between Owners and Contractors in Successful and Unsuccessful Projects
Authors: Lokeshwaran M  , Aswin Bharath A
Published: March 2023

The construction industry is known for its high risk of project delays, which can lead to cost overruns and reduced project performance. This literature review examines the causes of delays in construction projects, as well as the mitigation strategies used by owners and contractors to address these issues. The study also explores the gaps between owners and contractors in successful and unsuccessful projects, highlighting the need for improved communication and collaboration between these two groups. The review found that the most common causes of delay in construction projects are design changes, poor project management, labour shortages, and material shortages. To mitigate these issues, owners and contractors employ various strategies, including scheduling and resource allocation, risk management, and project monitoring and control. The study also revealed that successful projects are characterized by effective communication and collaboration between owners and contractors, while unsuccessful projects often result from a lack of trust and cooperation. The review suggests that owners and contractors can improve project outcomes by establishing clear project goals, developing a shared understanding of project risks and requirements, and fostering open communication throughout the project lifecycle. Overall, this literature review highlights the importance of addressing the causes of delay in construction projects through effective mitigation strategies and improved collaboration between owners and contractors. By implementing these measures, stakeholders can improve project outcomes and reduce the risk of costly delays and overruns.
EFFECT OF SODIUM GLUCOSE CO-TRANSPORTER 2 INHIBITORS ON LIPID LEVELS IN NEWLY DIAGNOSED HYPERTENSIVE PATIENTS WITH TYPE 2 DIABETES MELLITUS
Authors: Doğanay Birsen , Özcan Çelebi Özlem
Published: March 2023

Aim: This study aimed to examine the effects of sodium glucose
cotransporter 2 inhibitors (SGLT-2i) on lipid levels at 12 weeks of
follow-up in newly diagnosed hypertensive (NDHT) patients with type
2 diabetes mellitus (T2DM).
Methodsː This retrospective study, 236 NDHT patients with T2DM
were included. The SGLT-2i group consisted of patients who received
SGLT-2i (empagliflozin or dapagliflozin) in addition to stable triple
combination treatment. The control group was selected over NDHT
patients with T2DM who did not receive SGLT-2i and matched with the
SGLT-2i group in terms of baseline risk factors by propensity score.
The laboratory findings of the patients were compared retrospectively
at the time of diagnosis of NDHT (baseline) and at 12-month followup.
Resultsː The decrease in fasting blood glucose and hemoglobin
A1C levels was higher in the SGLT-2i group than control group.
Although both groups received similar antihypertensive therapy, the
improvement in lipid profile was higher in the SGLT-2i group. Glycemic
control and side effects were similar in empagliflozin and dapagliflozin
groups. However, greater improvement in lipid profiles was detected
in dapagliflozin users.
Conclusionsː In NDHT patients with T2DM, the addition of SGLT2i to treatment management in cases where glycemic control is not
achieved is associated with more improvement of the lipid profile
without significant side effects. However, the effects of various SGLT2i agents on this improvement may be different.

Política externa, soberania e direitos individuais dos estrangeiros – o epílogo do caso Battisti à luz de uma análise histórica da jurisprudência do STF (Supremo Tribunal Federal)
Authors: Borges Daniel Damasio
Published: March 2023

O modo pelo qual o Estado brasileiro direciona e implementa a sua política externa afeta os direitos individuais de estrangeiros, especialmente em matéria de expulsão e de extradição. A recente decisão do STF sobre o caso Battisti é disso uma ilustração. Esse caso nos dá o fio condutor para refletir sobre essa relação entre política externa e direitos individuais. Ao longo de sua história, o STF tem adotado duas noções de soberania nos casos envolvendo a política externa brasileira. A primeira é no sentido de uma soberania limitada pela Constituição, em que os direitos dos estrangeiros devem ser assegurados. A segunda é na acepção do poder irrestrito do Poder Executivo, não suscetível de ser controlado pelo Poder Judiciário. O artigo procura analisar os acórdãos do STF em que esses dois sentidos aparecem. Para levar a efeito essa análise, fez-se um estudo da jurisprudência do STF, abordando casos históricos sobre essa questão desde a primeira Constituição Republicana de 1891. Se o primeiro conceito de soberania evita arbítrios do Poder Executivo, o segundo os justifica.
Prestaciones patrimoniales de carácter público
Authors: Palao Taboada Carlos
Published: March 2023

El concepto de «prestación patrimonial de carácter público» (PPCP) se utiliza por el artículo 31.3 CE con la única finalidad de delimitar el ámbito de la reserva de ley y es aplicable a prestaciones de cualquier naturaleza, públicas y privadas, tributarias o no. Por consiguiente, dicho concepto no designa a una determinada clase de prestaciones en sentido material. Sin embargo, algunas afirmaciones del Tribunal Constitucional vincularon el concepto de PPCP al de tributo y sobre esta base, respaldada por el legislador, un sector relevante de la doctrina sostuvo la existencia de un concepto constitucional de tributo más amplio que el ordinario. En virtud de esta tesis, la retribución pagada por los usuarios de los servicios públicos indispensables (por tanto PPCP) tenía que tener necesariamente, por mandato constitucional, naturaleza tributaria, es decir, de tasa, y no de «tarifa» o precio privado, independientemente de la forma de gestión del servicio. Esta tesis, que pasó por diversas vicisitudes normativas y jurisprudenciales, fue finalmente abandonada por la reforma que realizó en esta materia la Ley 9/2017, de Contratos del Sector Público (LCSP), que calificó a las tarifas de los servicios públicos con un régimen de gestión de Derecho privado de «PPCP no tributarias». Este concepto, que causó una cierta perplejidad en la parte de la doctrina para la que esta expresión encierra una contradicción en los términos, significa sencillamente la definitiva desaparición, sancionada por la STC 63/2019, del erróneo concepto constitucional de tributo.
Las PPCP consistentes en la retribución por la utilización de servicios públicos necesarios deben distinguirse nítidamente de aquellas otras que consisten en la obligación de soportar una carga o gravamen sin que exista una contraprestación del ente público directa o indirectamente beneficiario. Esta segunda clase de PPCP plantea problemas constitucionales distintos de los suscitados por la clase anterior; por ello mantenerlas debidamente separadas es una exigencia de claridad, no siempre respetada suficientemente ni por el legislador ni por el TC. Las PPCP de esta segunda clase entran sin dificultad en la amplia categoría de los tributos parafiscales, algo que advirtió también confusamente el legislador de la LCSP cuando sustituyó la norma sobre exacciones parafiscales contenida en la DA Primera de la LGT por otra relativa a las PPCP.
El trabajo se complementa con un examen de la naturaleza de los gravámenes temporales energético y sobre entidades de crédito establecidos por la Ley 38/2022, de 27 de diciembre, que la propia Ley califica como «PPCP no tributarias».
