The present article has as its theme public policies in the democratic state: a tool for the promotion of citizenship,delimiting itself to aspects related to the guarantee of the rights expressed in the Federal Constitution of 1988 for citizensthrough State actions. The study seeks to answer the problem question: what is the role of public and social policiesin the realization of citizens’ rights? For that, it was based on the hypothesis that, through public policies, one seeks toobtain social balance, in order to comply with what is expressed by the Brazilian Constitution. In this context, the mainjustifi cation for the development of research on the proposed theme is that social inequalities are unquestionable in Brazil,being fully relevant to carry out studies and research aimed at a better understanding of the means available to achievethe minimization of this situation. The general objective of this study is to analyze how public policies can contributeto the promotion of citizens’ rights, considering the responsibility of the State in its implementation. For this purpose, abibliographical methodology research was developed, based on national legislation, and authors such as Tavares (2020);Barroso (2013); Fernandes (2020); Secchi (2020), among others who discuss the subject. The research indicated thatthe rights enacted by the Federal Constitution of 1988 are consolidated by the Democratic State of Law through socialpublic policies, which represent important tools for building citizenship.

Authors: Diógenes João Paulo Peixoto
Published: February 2024

Characterized by the principles of stimulating individual diff erences, valuing each individual, learning through cooperation and living with diversity as a single purpose, which is the role of education and its school management, above all to benefi t each individual in an environment of freedom and autonomy recognizing among their peers the same legal space that exists for themselves, this analysis can conclude that the meaning of inclusion also encompasses those who are excluded from educational environments, not just students with special needs. Many educational institutions have adapted their school management systems to adapt to the specifi cities of their students, prioritizing general effi ciency, administrative effi ciency and human development. Families are now increasingly familiar with the rights of children with disabilities and work strongly with schools in defense of the inclusion of all in society and the educational environment.

Published: February 2024

The theme of literacy at the right age will be discussed in this article, and its importance for an adequate formation of the student within basic education. The work is a literature review based on authors who had relevant productions within the area of interest of this work. The hypothesis raised here is to what extent literacy is a prerequisite for the process of educating the student for the other stages that make up basic education. The objectives pursued here are to discuss the importance of literacy at the right age for the development of the student in the other stages of schooling; discuss how these processes develop, discuss how they occur and are understood by students. The work was structured in three subtopics, which, one by one, were developing and qualifying the production presented here. The fi rst subtopic focused on the general concept of literacy, the second discussed how literacy occurs, ending with the third topic that presents the importance of this process for the student’s life. We saw then that literacy at the right age is, in today’s society, more than just making the student able to join syllables and read words, it has the ability to present a wide and connected world, where reading and, mainly, interpretation of what is presented to you is extremely important. Thus, literacy at the right age is more than ever a fundamental right of children up to eight years old.

Alteração de Prenome e Sobrenome na Via Extrajudicial: uma Análise da Lei 6.015/73 Alterada pela Lei 14.382/22
Authors: Dias Raiane França , Oliveira Denis Marcio Jesus
Published: February 2024

This article aims to address the importance of changing one’s fi rst and last name through an extrajudicial process, regulated by Law No. 6.015/73 on Public Records, which was recently amended by Law No. 14.382/2022. As provided in Article 16 of the Civil Code, every person has the right to a name, which encompasses both the fi rst and last names. Because this is a recent topic, the use of periodicals and specialized doctrine was essential for the development of the work. Therefore, it is important to note that the possibility of changing one’s fi rst and last name through an extrajudicial process has brought more speed and effi ciency to the processes, relieving the Judiciary and allowing interested parties to make the change without the need to resort to a court action. With the entry into force of Law No. 14.382/2022, the rules for name changes have been updated, enabling more people to make the change without having to prove the existence of damages or justify the need for the change. The research conducted seeks to allow a better understanding of the changes in the legislation and to highlight the importance of staying updated about changes and innovations in Civil Law.
Direito ao tratamento de crianças com síndromes epilépticas refratárias
Authors: Ferraz Solrac Gigante , Meira Rodrigo Santos
Published: February 2024

The use of cannabidiol in children with refractory epileptic syndromes is a subject that has generated heated debates in the medical and legal community. Although cannabidiol is a substance found in the marijuana plant, its use for medicinal purposes has been studied and approved in several countries, including Brazil. However, despite its proven eff ectiveness in treating some diseases, access to this treatment is still a challenge for many families, who face bureaucratic and legal barriers to obtaining medication. Given this, the question is what is the impact of bureaucratic and legal barriers on the use of cannabidiol in children with refractory epileptic syndromes, and how to guarantee the right of access to this treatment in a safe and eff ective way? The primary hypothesis is that the use of cannabidiol in children with refractory epileptic syndromes is eff ective and can provide a signifi cant improvement in the quality of life of these patients. The general objective of this article is to analyze the challenges and opportunities in the right of access to cannabidiol treatment in children with refractory epileptic syndromes. It was noticed that bureaucratic and legal barriers in the use of cannabidiol in children with refractory epileptic syndromes have a signifi cant impact, making access to this treatment diffi cult. This can result in delays in the initiation of treatment, deprivation of the therapeutic benefi ts of cannabidiol, and increased distress for these children and their families. In addition, it is essential to promote the awareness and training of health professionals about the benefi ts and risks of cannabidiol, so that they can make informed and informed decisions when prescribing this treatment.

The objective of this work is to highlight the challenges faced by Physical Education in remote teaching. This discipline is fundamental for the formation of critical individuals, capable of developing their motor and psychomotor skills, and inter acting with the world a round them. However, in the context of remote teaching, Physical Education faces new obstacles that hinder its eff ectiveness. To emphasize the importance of Physical Education in the teaching-learning process in times of remote teaching, qualitative bibliographical research was carried out that highlighted the benefi ts of this discipline of teaching. In this sense, the importance of Physical Education and the inclusion of cross-cutting themes for building a society based on mutual respect, without any kind of distinction or discrimination, is highlighted. In view of this, it is necessary for society to strive to minimize and solve the challenges imposed by Physical Education in remote teaching, in order to guarantee that this discipline continues to contribute to the formation of critical and refl ective individuals, capable of developing the motor skills and psychomotor skills, even in virtual contexts. In short, this work points out the challenges faced by Physical Education in remote teaching and highlights the importance of including cross-cutting themes for the construction of amorous and egalitarian society.
As nuances do controle de constitucionalidade nos entes municipais com ênfase nas disposições jurisprudenciais
Authors: Pinheiro Hana Ferber Corezzi Ferrer
Published: February 2024

The present work aims to study the nuances of judicial review in municipal entities, defi ning its parameters and emphasizing especially the jurisprudential constructions. For this purpose, the descriptive method was used, supported by research articles, bibliographical research of doctrinal works in jurisprudence of the Superior Courts, as well as materials available on the internet. These documents were then read and, through the results obtained, a broad, critical and refl ective discussion was carried out, which culminated in the general conclusion that the concentrated judicial review is applicable to municipal norms, but not fully, a since it has limited parameters. As a rule, the said control is carried out using the norms present in the State Constitution as a parameter, through the local Court of Justice, through the initiative of legitimate parties also provided for in the State Charter. Thus, only in the face of norms of mandatory reproduction is the Federal Constitution used as a parameter, for the purpose of controlling municipal constitutionality, avoiding confl icting decisions with the supreme norm of the Brazilian legal system. In this sense, it is important to highlight that this possibility arose from jurisprudential constructions, not being expressly provided for by law. In addition, despite the existence of doctrinal divergence, the impossibility of concentrated control of constitutionality using Municipal Organic Laws as a parameter has been demonstrated. That said, given municipal regulations that violate it, it should be restricted to legality control.

Authors: SHIDOSHI Christian José , Santos Claudio Luciano dos
Published: February 2024

Citrus Greening, also known as Huanglongbing (HLB), is one of the most devastating diseases affecting citrus cultivation worldwide. This disease is caused by a bacterium transmitted by psyllids, insects that feed on plant sap. Greening results in severe symptoms such as wilting and yellowing of the leaves, compromising the production and quality of the fruits, and in many cases, leading to the death of the trees. The losses have been significant in various parts of the world, especially in Florida, where crops have been decimated, resulting in substantial economic damages to the citrus sector. Given this threat, the adoption of appropriate control measures and strategies is essential for effective prevention and combat of the disease. The general objective of this work is to investigate and present a synergistic and integrated approach to measures and control strategies for Citrus Greening, aiming to prevent the spread of the disease, combat its propagation, and promote proper and sustainable management of citrus crops. The methodology used in this work consists of a comprehensive and systematic bibliographic review on the topic of Citrus Greening control.

Published: February 2024

A variety of illnesses, including arthritis, tenosynovitis, stunted growth, and malabsorption syndrome, are caused by Avian Reoviruses (ARVs), which have become more prevalent in Egypt during recent years and resulted in significant economic losses. This study investigated 27 suspected samples collected from 14 broiler breeders and 13 broilers suffering from immunosuppression, decreased body weight, and diarrhea. Fourteen samples tested positive based on RT-PCR, and the virus could be isolated from ten samples in Specific Pathogen Free (SPF) embryonated chicken eggs. Ten isolates were subjected to molecular and genetic analysis of the S1 gene (sigma C) and S2 gene (sigma A). The amino acid identity of the S1 gene revealed that these viruses are closely related to the viruses that were identified in Israel during 2020 (91.8%-97.2% identity) and belonged to the genetic cluster 5 (genotype 5), which also includes some viruses that are circulating in the United States and Canada. They also showed weak similarity (48.9%-50.2%) with the available vaccine strains in the Egyptian field that belong to cluster 1, genotype 1. The S2 gene showed amino acid homology of 91.7%-98.2% with the current vaccine used in Egypt. However, the Egy-Reo-7-2021 virus had the lowest similarity (84.2%-87.6%) to the available vaccine. It is hypothesized that the difference between field and vaccine strains may have contributed to the failure of current vaccinations to produce protective immunity against current ARV strains circulated in Egypt, which made the disease a problem to the poultry industry. Developing homologous vaccines and evaluating their potency and efficacy are required in Egypt.

Published: February 2024

Abstract. Comprehensive observations of hydroxyl (OH) and hydroperoxy (HO2) radicals were conducted in October 2019 at a coastal continental site in the Pearl River Delta (YMK site, 22.55∘ N, 114.60∘ E). The daily maximum OH and HO2 concentrations were (4.7–9.5) × 106 and (4.2–8.1) × 108 cm−3, respectively. The synchronized air mass transport from the northern cities and the South China Sea exerted a time-varying influence on atmospheric oxidation. Under a typical ocean-atmosphere (OCM), reasonable measurement model agreement was achieved for both OH and HO2 using a 0-D chemical box model incorporating the regional atmospheric chemistry mechanism version 2-Leuven isoprene mechanism (RACM2-LIM1), with daily averages of 4.5 × 106 and 4.9 × 108 cm−3, respectively. Land mass (LAM) influence promoted more active photochemical processes, with daily averages of 7.1 × 106 and 5.2 × 108 cm−3 for OH and HO2, respectively. Heterogeneous uptake had certain effects on HOx chemistry, but the influence of the halogen mechanism was limited by NOx level. Intensive photochemistry occurred after precursor accumulation, allowing local net ozone production comparable with surrounding suburban environments (5.52 ppb h−1 during the LAM period). The rapid oxidation process was accompanied by a higher diurnal nitrous acid (HONO) concentration (> 400 ppt). After a sensitivity test, HONO-related chemistry elevated the ozone production rate by 33 % and 39 % during the LAM and OCM periods, respectively. The nitric acid (P(HNO3)) and sulfuric acid (P(H2SO4)) formation rates also increased simultaneously (∼ 43 % and ∼ 48 % for LAM and OCM sectors, respectively). In the ozone-prediction test, simulated O3 decreased from ∼ 75 ppb to a global background (∼ 35 ppb) without the HONO constraint, and daytime HONO concentrations were reduced to a low level (∼ 70 ppt). For coastal cities, the particularity of the HONO chemistry tends to influence the ozone-sensitive system and eventually magnifies the background ozone. Therefore, the promotion of oxidation by elevated precursors deserves a lot of attention when aiding pollution mitigation policies.
Measurement report: Source attribution and estimation of black carbon levels in an urban hotspot of the central Po Valley: An integrated approach combining high-resolution dispersion modelling and micro-aethalometers
Authors: Veratti Giorgio , Bigi Alessandro , Stortini Michele , Teggi Sergio , Ghermandi Grazia
Published: February 2024

Abstract. Understanding black carbon (BC) levels and their sources in urban environments is of paramount importance due to their far-reaching health, climate and air quality implications. While several recent studies have assessed BC concentrations at specific fixed urban locations, there is a notable lack of knowledge in the existing literature on spatially resolved data alongside source estimation methods. This study aims to fill this gap by conducting a comprehensive investigation of BC levels and sources in Modena (Po Valley, Italy), which serves as a representative example of a medium-sized urban area in Europe. Using a combination of multi-wavelength micro-aethalometer measurements and a hybrid Eulerian-Lagrangian modelling system, we studied two consecutive winter seasons (February–March 2020 and December 2020–January 2021). Leveraging the multi-wavelength absorption analyser (MWAA) model, we differentiate sources (fossil fuel combustion, FF, and biomass burning, BB) and components (BC vs. brown carbon, BrC) from micro-aethalometer measurements. The analysis reveals consistent, minimal diurnal variability in BrC absorption, in contrast to FF-related sources, which exhibit distinctive diurnal peaks during rush hours, while BB sources show less diurnal variation. The city itself contributes significantly to BC concentrations (52 % ± 10 %), with BB and FF playing a prominent role (35 % ± 15 % and 9 % ± 4 %, respectively). Long-distance transport also influences BC concentrations, especially in the case of BB and FF emissions, with 28 % ± 1 % and 15 % ± 2 %, respectively. When analysing the traffic related concentrations, Euro 4 diesel passenger cars considerably contribute to the exhaust emissions. These results provide valuable insights for policy makers and urban planners to manage BC levels in medium-sized urban areas, taking into account local and long-distance sources.
Opinion: Understanding the impacts of agriculture and food systems on atmospheric chemistry is instrumental to achieving multiple Sustainable Development Goals
Authors: Tai Amos P. K. , Luo Lina , Luo Biao
Published: February 2024

Abstract. Agriculture and food systems play important roles shaping atmospheric chemistry and air quality, most dominantly via the release of reactive nitrogen (Nr) compounds, but also via agricultural burning, energy use, and cropland and pastureland expansion. In this opinion, we first succinctly review our current understanding of agricultural and food-system emissions of Nr and other atmospherically relevant compounds, their fates and impacts on air quality, human health and terrestrial ecosystems, and how such emissions can be potentially mitigated through better cropland management, livestock management and whole food-system transformation. With that, we highlight important knowledge gaps that warrant more extensive research, and argue that we scientists need to provide a more detailed, process-based understanding of the impacts of agriculture and food systems on atmospheric chemistry, especially as the importance of emissions from other fossil fuel-intensive sectors is fading in the face of regulatory measures worldwide. Such knowledge is necessary to guide food-system transformation in technologically feasible, economically viable, socially inclusive, and environmentally responsible manners, and essential to help society achieve multiple Sustainable Development Goals (SDGs), especially to ensure food security for the people, protect human and ecosystem health, improve farmers’ livelihood, and ultimately help communities achieve socioeconomic and environmental sustainability.
Constraining the carbon cycle in JULES-ES-1.0
Authors: McNeall Douglas , Robertson Eddy , Wiltshire Andy
Published: February 2024

Abstract. Land surface models are an important tool in the study of climate change and its impacts, but their use can be hampered by uncertainties in input parameter settings and by errors in the models. We apply uncertainty quantification (UQ) techniques to constrain the input parameter space and corresponding historical simulations of JULES-ES-1.0 (Joint UK Land Environment Simulator Earth System), the land surface component of the UK Earth System Model, UKESM1.0. We use an ensemble of historical simulations of the land surface model to rule out ensemble members and corresponding input parameter settings that do not match modern observations of the land surface and carbon cycle. As JULES-ES-1.0 is computationally expensive, we use a cheap statistical proxy termed an emulator, trained on the ensemble of model runs, to rule out parts of the parameter space where the simulator has not yet been run. We use history matching, an iterated approach to constraining JULES-ES-1.0, running an initial ensemble and training the emulator, before choosing a second wave of ensemble members consistent with historical land surface observations. We successfully rule out 88 % of the initial input parameter space as being statistically inconsistent with observed land surface behaviour. The result is a set of historical simulations and a constrained input space that are statistically consistent with observations. Furthermore, we use sensitivity analysis to identify the most (and least) important input parameters for controlling the global output of JULES-ES-1.0 and provide information on how parameters might be varied to improve the performance of the model and eliminate model biases.

Abstract. Supraglacial lakes form on the Greenland ice sheet in the melt season (May to October) when meltwater collects in surface depressions on the ice. Supraglacial lakes can act as a control on ice dynamics since, given a large enough volume of water and a favourable stress regime, hydrofracture of the lake can occur, which enables water transfer from the ice surface to the bedrock, where it can lubricate the base. The depth (and thus volume) of these lakes is typically estimated by applying a radiative transfer equation (RTE) to optical satellite imagery. This method can be used at scale across entire ice sheets but is poorly validated due to a paucity of in situ depth data. Here we intercompare supraglacial lake depth detection by means of ArcticDEM digital elevation models, ICESat-2 photon refraction, and the RTE applied to Sentinel-2 images across five lakes in southwest Greenland. We found good agreement between the ArcticDEM and ICESat-2 approaches (Pearson's r=0.98) but found that the RTE overestimates lake depth by up to 153 % using the green band (543–578 nm) and underestimates lake depth by up to 63 % using the red band (650–680 nm). Parametric uncertainty in the RTE estimates is substantial and is dominated by uncertainty in estimates of reflectance at the lakebed, which are derived empirically. Uncertainty in lake depth estimates translates into a poor understanding of total lake volume, which could mean that hydrofracture likelihood is poorly constrained, in turn affecting ice velocity predictions. Further laboratory studies to constrain spectral radiance loss in the water column and investigation of the potential effects of cryoconite on lakebed reflectance could improve the RTE in its current format. However, we also suggest that future work should explore multi-sensor approaches to deriving lake depth from optical satellite imagery, which may improve depth estimates and will certainly result in better-constrained uncertainties.

Ընտանեկան ձեռնարկատիրությունը որպես ձեռնարկատիրական գործունեության ինքնուրույն ինստիտուտ / Family Business as an Indipendent Institute of Entrepreneurial Activity
Authors: MKRTCHYAN HAYK
Published: February 2024

The purpose of the article is to present the current state of legal regulation of the
institution of family entrepreneurial activities, because currently, civil, family, and
entrepreneurial law need to be reinterpreted and developed, which will enable them to
move along with modern social and economic factors. The existing legal regulation of
family entrepreneurship is not sufficient to protect and ensure the rights and legal
interests of the participants of these legal relations.
The range of participants on the doctrinal and legislative levels is not specified. A conflict emerges between modern economic and social norms and family entrepreneurship activities. In the mentioned work, an attempt was made to present recommendations related to the improvement of this institution and to identify its features, which will enable a more accessible understanding of it and improve the legislation.
Los informes de sostenibilidad de empresas chilenas, españolas y mexicanas: un análisis crítico del género
Authors: Basanta Almudena , Vangehuchten Lieve
Published: February 2024

En este artículo se plantea un análisis crítico del género del informe de sostenibilidad en tres de las principales variantes dialectológicas del idioma español, a saber el español chileno, el mexicano y el peninsular, que a su vez se corresponden con tres zonas con diferentes niveles de implementación de Responsabilidad Social Corporativa (RSC). El corpus se compone de los informes de seis empresas de los sectores extractivo y financiero, especialmente sensibles a la sostenibilidad y con grandes desafíos para alcanzar el equilibrio entre las personas, el planeta y el beneficio. Partimos del supuesto que el discurso de la RSC es una forma de comunicación empresarial híbrida que desempeña, además de su papel informativo primordial, las funciones comunicativas de legitimar las acciones de la empresa, gestionar su reputación y establecer un diálogo sostenible con las partes interesadas. Mediante un análisis léxico-semántico discursivo que hace uso de la modelización de temas o topic modeling se comparan los informes de los tres subcorpus y se llega a la conclusión de que en el subcorpus peninsular la comunicación de la RSC es principalmente de índole estratégica, mientras que en los subcorpus chileno y mexicano también es claramente responsiva, lo que se puede explicar desde una perspectiva transcultural e institucional. En cuanto a los interdiscursos que sirven para reforzar el discurso general de RSC, llama la atención que los informes chilenos y mexicanos recurren significativamente más a las estrategias comunicativas de la legitimación y la reputación, de manera que quieren claramente explotar el potencial de promoción del informe más de lo que parece ser el caso en el subcorpus peninsular. Finalmente, al tomar en cuenta los factores extratextuales, se observa que la estrategia de la omisión también ejerce una influencia importante en el discurso de este género.
Contribución de la semántica combinatoria al desarrollo de herramientas digitales multilingües
Authors: Domínguez Vázquez María José
Published: February 2024

El presente trabajo describe cómo la semántica combinatoria ha contribuido al diseño de tres prototipos de generación automática de esquemas argumentales del nombre en español, francés y alemán – Xera, Combinatoria y CombiContext. Asimismo, da cuenta de la importancia del conocimiento sobre la interfaz sintáctico-semántica argumental en una situación de producción en lenguas extranjeras. Tras un apartado descriptivo sobre el diseño, tipología y niveles informativos de los recursos, sigue una exposición sobre el papel fundamental del significado combinatorio —relacional y categorial— en su desarrollo. El estudio detalla diferentes filtros semánticos aplicados en la selección, organización y expansión del caudal léxico, siendo estas piezas clave para la generación de frases nominales mono y biargumentales gramaticalmente correctas y semánticamente aceptables.

A malária, uma parasitose de grande impacto na saúde pública mundial, está associada a sequelas neurológicas, cognitivas e comportamentais em humanos e modelos experimentais murinos, principalmente, nas formas graves da doença e sobretudo na malária cerebral. Entretanto, danos cognitivos manifestos como sequelas da malária humana são observados mesmo após episódios de malária não grave, e até após infecções assintomáticas. Embora pouco documentadas, tais consequências da doença são também relatadas em estudos sobre malária não grave em modelo experimental murino. Aqui, abordaremos as sequelas cognitivo-comportamentais associadas às malárias não graves humana e murina e no comprometimento da homeostasia cognitiva em infecções assintomáticas.
