Cuestiones jurídicas generadas por los smart contracts en el comercio electrónico B2C: foro, jurisdicción aplicable y derecho de desistimiento dentro del ordenamiento jurídico español
Authors: Martínez Boada Javier
Published: July 2024

El uso del comercio electrónico para celebrar relaciones de consumo cada vez toma más protagonismo en la sociedad de la información. El constante desarrollo de las tecnologías hace que las plataformas existentes puedan beneficiarse de sus características; sin embargo, también traen consigo diferentes cuestiones jurídicas que deben mitigarse a fin de proteger los intereses y derechos de los usuarios. La tecnología blockchain es una de las tecnologías que viene a revolucionar el ámbito de las relaciones electrónicas B2C gracias a su carácter transnacional, descentralización, garantía de confianza, inmutabilidad y a una de sus funcionalidades más características: los smart contracts. Este tipo de acuerdos se distinguen por su automatización y autoejecución, caracteres que a priori pueden poner en riesgo la legislación existente sobre consumidores y usuarios. Asimismo, las oportunidades que brinda blockchain de cara a que los usuarios puedan actuar de forma irreconocible puede poner en jaque la normativa encargada de determinar la competencia judicial internacional y la ley aplicable a las relaciones jurídicas de consumo B2C. Este trabajo analiza la aplicabilidad de los smart contracts en el ámbito del comercio electrónico, en especial en el de empresas con consumidores (B2C) y estudiar los posibles inconvenientes que generan sobre la normativa existente a fin de analizar si es necesario adaptar la legislación a estas tecnologías.
El rol del juez de garantía en el debate de medidas cautelares personales. Revisión normativa de los sistemas procesales penales de Chile, Uruguay y Argentina federal
Authors: Blanco Suarez Rafael
Published: July 2024

Las funciones que los tribunales de garantía o de control deben cumplir en los modelos acusatorios de corte adversarial son fundamentales para la debida protección de los derechos y las garantías de todos los intervinientes, en especial del imputado y el acusado. Estas funciones resultan críticas para los debates en torno a la procedencia de las medidas cautelares personales y suponen por parte del juez la estricta observancia de los principios que regulan tales medidas y la fundamentación acerca del modo en que estos principios son aplicados en cada caso. Los tribunales de garantía deben definir y explicitar los estándares exigibles para cada tipo de medida cautelar personal solicitada por los litigantes, y reproducir en sus resoluciones los criterios empleados y los fundamentos utilizados para dar por acreditados o desestimados los requisitos de las medidas cautelares personales, como son los presupuestos materiales de estas y la necesidad de cautela.

Published: July 2024

Introduction & Objective: The diversity of individuals living with T1D has increased, driven by Hispanic (H) and non-Hispanic Black (NHB) populations. Yet, whether H and NHB populations have different rates of SAB+ than other groups, which can impact clinical care and research opportunities, has not been well characterized. Area deprivation and race/ethnicity are strongly associated with each other and have compounding and adverse effects on diabetes-related health outcomes. We examined TrialNet data from relatives of persons with T1D screened for pancreatic autoantibodies and evaluated the frequency of SAB+ by race/ethnicity and area deprivation.

Methods: Persons (n=28330) screened between 4/9/19-12/31/22 were included. Race/ethnicity was categorized as non-Hispanic white (NHW), H, NHB, and non-Hispanic other (NHO). Home address zip codes were used to assign an Area Deprivation Index, a Health and Human Services Administration index incorporating neighborhood income, education, employment, and housing that ranges from 1 (least deprived) to 100 (most deprived). Deprivation was analyzed in quintiles.

Results: A majority (80.7%) self-identified as NHW; fewer as H (9.8%), NHB (2.5%), and NHO (7.0%). Deprivation differed by race/ethnicity (NHW 46±23, H: 45±24, NHB: 53±23, and NHO: 39±25, p<0.001). SAB+ was more common in NHB and H than NHO and NHW individuals (Overall: 3.0%, NHB: 4.7%, H: 3.8%, NHO: 3.1%, NWH: 3.0%; χ2 p=0.02). Logistic regression identified a linear relationship between SAB+ and deprivation (Deprivation quintiles 1 to 5: 2.9%, 2.7%, 3.1%, 3.1%, 3.5%; p=0.04).

Conclusion: These data suggest SAB+ status varies by both race/ethnicity and deprivation which warrants further investigation. Understanding patterns of autoantibody positivity that occur in diverse populations at risk for T1D is foundational to identifying persons who are SAB+ or in early stages of T1D who may now be eligible for preventive therapies.

Published: July 2024

Introduction & Objective: Longitudinal trends of glycemia and severe hypoglycemic events (SHE) among individuals with T1D are not well described, particularly in those using diabetes technologies (i.e., continuous glucose monitors [CGM], automated insulin delivery [AID]).

Methods: An online survey recruited adults with T1D through the T1D Exchange Registry or online communities from February-April 2021. Overall, 2,044 individuals completed the survey and eligible participants were invited to complete follow-up survey from April-May 2023. Participants self-reported CGM use, insulin delivery method, HbA1c, impaired awareness of hypoglycemia (IAH), and SHE.

Results: Of 1,999 eligible individuals, 1,056 completed the follow-up survey and were eligible for analysis (53% response rate; mean age: 46 y; mean T1D duration: 29 y; 71% female; 97% White). Most reported using CGMs at baseline (91.8%) and follow-up (94.4%), and use of AID increased (baseline: 53.5%; follow-up: 69.0%; Table). At baseline, 61.7% reported HbA1c <7% vs. 67.4% at follow-up. Rates of IAH and SHE in the prior year were similar at both time points.

Conclusion: Despite nearly universal CGM usage and increased adoption of AID, one-third of respondents did not achieve HbA1c targets and the proportion of respondents with IAH and SHE did not decline. These results highlight the need for innovative approaches to improve T1D care.

Published: July 2024

Islet transplantation (ITx) is an established treatment for recurrent, severe hypoglycemia in type 1 diabetes, however, requires lifelong immunosuppression (IS) which can be nephrotoxic. We conducted a risk regression to identify factors associated with progression to Stage 3 CKD (S3CKD) or worse post-ITx. We used data from adults undergoing ITx alone at the University of Alberta Hospital between March 11 1999 and Oct 1 2019 with >1 year follow up. IS included tacrolimus and sirolimus/mycophenolate. We identified episodes of irreversible S3CKD as eGFR <60 ml/min/1.73m2 for ≥90d in addition to a final 12m average eGFR below threshold. We conducted multivariable competing risk (death) regression with the covariates: baseline eGFR, age at first ITx, diabetes duration, total ITx count, mean tacrolimus trough levels in year 1 post-ITx, number of acute kidney injury (AKI) events in year 1 post-ITx, sex, baseline hypertension and sirolimus exposure. We identified 199 adults (41% M followed for a median 76.1m [IQR 38.0-131.6]), of which 47.7% progressed to S3CKD within a median 28m [IQR 9-57]. Female sex and more AKI events substantially increased the risk of progression to S3CKD (HR 1.50, [95% CI 1.31,1.80, p =0.004; HR 1.21, [95% CI 1.02, 1.45, p=0.028] respectively). Older age at first-ITx, lower baseline eGFR and longer diabetes duration had modest effect of significance on the risk of progression. Mean tacrolimus level in the first year post-ITx, number of ITx, baseline hypertension and exposure to sirolimus were not significant predictors for the risk of progression to S3CKD. No sex differences were found in risk for Stage 4 or 5 CKD. IS may put female ITx recipients at greater hazard of progressing to S3CKD, independently of other potential risk factors. Further study is required to elucidate this association, which could translate into sex-specific strategies to manage IS post-ITx. Effective IS regimens without nephrotoxicity remain an important goal.

Published: July 2024

Introduction & Objective: It is thought that viral infection triggers islet inflammation, an interferon signature, and autoimmunity resulting in type 1 diabetes. Despite extensive research, an inciting virus has not been identified. We hypothesized that impaired RNA editing and accumulation of double-stranded RNA in beta cells triggers an interferon response, causing islet inflammation, autoimmunity, and beta cell destruction. While RNA editing regulated by adenosine deaminases acting on RNA (ADAR) has been studied in some organs and in cancer, little is known about the role of ADAR in human islets.

Method: To elucidate the role of ADAR1 in human islets, we first studied ADAR expression and distribution in human pancreas across postnatal developmental timeline (1 day, 4 months, 2, 6, 10, 35 years). Then we transduced human pseudoislets with a shRNA for ADAR and examined their function and gene expression. The transduced pseudoislets were also transplanted into NSG mice. Insulin secretion was measured and grafts were studied.

Results: We found that ADAR1 expression at all ages was greater in endocrine cells than acinar cells. Using the shRNA approach, ADAR mRNA levels were reduced by 70% (n=11 donors). After 7-day culture, expression of dsRNA sensors, IFNB1, IRF7, IRF9, and interferon-stimulated genes was increased while INS and MAFA expression was reduced in ADAR knockdown islets without changes in insulin secretion. However, 3 weeks post transplantation, glucose/arginine-stimulated human insulin secretion was significantly decreased in mice with the ADAR shRNA graft compared with scrambled shRNA control graft (0.117 vs 0.300 ng/mL, p=0.0001, n=3 donors). Analysis of pseudoislet grafts 4 weeks after transplantation showed marked accumulation of mouse CD45+ cells around ADAR-knockdown islet grafts.

Conclusion: Interruption of RNA editing in human islets activates the interferon signaling pathway leading to islet inflammation and beta cell dysfunction.

Biogenic Degradation of Lignite Coal from Pakistani Coal Mine and Extraction of Humic Acid through Pretreatment Strategies by Fungal Isolate
Authors: N Fatima
Published: July 2024

The utilization of white rot fungal strain for degradation of low rank coal from coal environments is considered to be the best choice for converting raw coal into different kinds of valuable by products. NF-1, a fungal strain was isolated from coal mine of Thar region of Pakistan. For enhancing the process of biodegradation, the indigenous fungal isolate was used in the study. The lignite (low rank) coal sample degradation initiated by NF-1 strain were undergone through optimization process and had shown considerable production of organics at 1.5% Glucose, 1% coal loading ratio and 7 days of incubation period. The FTIR analysis of untreated coal and treated coal after solubilization was performed in order to observe changes in structural pattern by NF-1 fungal isolate. NF1 has the ability to break down the aromatic side linkages and attacking the amine and carboxyl groups. Scanning electron microscopy (SEM) of the coal treated by NF-1 strain was analyzed to investigate the attachment and adherence of the fungal mycelium on the coal surface. At 200µm the NF-1 isolate hyphae has clearly entrapped the coal particles showing erosion and up to 50µm colonization and visible changes on the coal surface can be observed clearly. Moreover, the residual coal after fungal pretreatment was processed for extraction of humic acid as a byproduct for defining the effect of such biological pretreatments. The produced humic acid was analyzed on the basis of E4/E6 ratio and FTIR. The fungal pretreated humic acid has shown more improvement in E4/E6 ratio as well as presence of functional groups related to humic acid through FTIR. This explains that the isolate NF1 have ability to speed up the biodegradation process and shows an aptitude of producing valuable by products i.e. humic acid as an alternative fuel.

Published: July 2024

Spina bifida or neural tube defect (NTD) is a spinal disorder that does not close completely, resulting in disability or developmental failure of the spinal cord. The cause of spina bifida has no definite reason, but there are several factors that are considered to increase the risk, namely folic acid deficiency, family history of spina bifida, and history of taking drugs. Patients with spina bifida will experience weakness in the lower extremity muscles, decreased ability to control urination, and decreased ability to carry out daily activities. The study used a case report study conducted at YPAC Surakarta for boys aged 15 years with spina bifida disorder. Physiotherapy plays a role in optimizing muscle strength, active movement of children, and improving functional abilities by using interventional stretching exercises, myofacial release, strengthening exercises, and a combination of Kegel Exercises and bridging exercises. After being treated for 6 times T1-T6 there was an increase in muscle strength as measured by manual muscle testing (MMT), changes in the range of motion of the joints (LGS) as measured by the goniometer, an increase in functional ability as measured by the Barthel Index.

A metodologia utilizada foi a pesquisa com base documental e a pesquisa bibliográfica. Contamos com o aporte teórico de Gimeno Sacristán (1999, 2000, 2011), Freire (2017), Arroyo (2013), Marcelo García (1999), Schön (2000), Imbernón (2011) e Laval (2004). Identificamos que a n.º 2/2019 define um projeto direcionado a formação de uma “personalidade global” (Laval, 2004) requerida pelo mercado, resultando na fragilidade da formação de professores. Conclui-se que a integração da competência como nuclear do currículo requer que a educação cumpra as funções que desconsideram os elementos essenciais para a sólida formação do professor.

A BNC-Formação tem sido motivo de grande debate no campo educacional no Brasil. A Resolução CNE/CP 2/2019 coaduna-se com outras reformas recentemente lançadas no cenário educacional brasileiro. Parte-se do pressuposto de que a BNC-Formação produz a padronização pragmatista da formação docente, alinhando-se à Pedagogia das Competências. Busca-se analisar criticamente o teor da Resolução CNE/CP 2/2019, em comparação com a Resolução CNE/CP 2/2015, desvelando o caráter pragmatista presente na primeira. Realizou-se um estudo de caráter bibliográfico e documental, tendo como base o materialismo histórico-dialético. Têm-se como apontamentos que a BNC-Formação padroniza uma supervalorização dos aspectos práticos e retrocede às conquistas reunidas na Resolução 2/2015. Outrossim, que ela agudiza a responsabilização dos docentes, assumindo a Pedagogia das Competências como vertente.

O artigo tem como objetivo analisar a atual política para a formação inicial e continuada de professores no Brasil. Para tanto, apresenta a seguinte problemática: Quais são as dimensões da profissionalização docente observadas nas orientações dos organismos internacionais e nas atuais diretrizes para formação de professores no Brasil? Com base na abordagem qualitativa, de metodologia bibliográfica e documental, a pesquisa considerou como fontes primárias as Resoluções CNE/CP Nº 2, de 20 de dezembro de 2019, e Nº 1, de 27 de outubro de 2020, além de documentos dos organismos internacionais. O referencial teórico valeu-se das análises de Meszáros (2011), Harvey (2016; 2017) entre outros. O principal resultado do estudo é a identificação da noção de profissionalização docente alicerçada em três dimensões: professor executor, professor gerencial e professor socioemocional.

O artigo focaliza o discurso que constitui o currículo da educação básica como referência para a Base Nacional Comum para a Formação Inicial de Professores (BNC-Formação) e os sentidos endereçados nessa articulação ao professor e à docência. A análise é orientada pela perspectiva pós-estrutural de currículo e pelas apropriações da Teoria Política do Discurso por esse campo, tencionando problematizar os efeitos discursivos da centralidade das aprendizagens essenciais dos estudantes da educação básica na política de formação de professores: a homologia de processos e as competências profissionais do professor para alcance da performance adequada para fazer aprender. Destaca-se o desejo (impossível) de controle total da produção curricular contextual, argumentando-se que em nome da igualdade e da equidade na educação, a centralização curricular acaba por produzir a exclusão da diferença.
Consumo cultural e racismo estrutural
Authors: Lucas Marcello Kochhann
Published: July 2024

Este artigo explora a relação entre consumo cultural e racismo estrutural, com foco em como reality shows como o Big Brother Brasil moldam as percepções públicas sobre raça e representatividade. Utilizando um estudo teórico-metodológico baseado na semiótica peirceana, analisamos o processo de significação de um trecho do conteúdo exibido na final do Big Brother Brasil 2023, da Rede Globo. A semiótica de Peirce oferece uma estrutura para compreender a relação entre o signo, o objeto e o interpretante, permitindo-nos explorar como os elementos visuais e sonoros presentes no programa contribuem para a construção e perpetuação de estereótipos raciais. A análise se concentra na identificação e classificação de signos como ícones, índices ou símbolos, investigando os níveis de significado atribuídos a eles e suas implicações culturais. Além disso, examinamos o impacto desse conteúdo nas discussões nas redes sociais e no debate público, considerando a alta audiência do programa e sua relevância como produto cultural popular. O artigo busca entender como a mídia de entretenimento influencia as narrativas sobre pautas como o racismo estrutural.

Introduction. The article investigates the ways to optimise the design of a truss-to-column connection in a frame structure made of round tubes. A steel lattice frame with a span of 66 m has been studied. A spanning member of a frame in the form of a truss transmits loads to a frame column through a rigid truss-to-column connection. In such structures, the maximum bending moments are applied to a truss-to-column connection, thus the problem of regulating its geometry is one of the objectives to be solved within the optimal designing. The aim of this paper is to create the most rational design solution for such a connection.

Materials and Methods. In the lattice frames, depending on the chosen design, 5 to 7 members subject to compression stress converge at its inner side. The conventional variants of executing this connection would require using the heavy wall tubes which would result in the excess of material consumption. Within the research, modeling and calculation of various configurations of the truss-to-column connection were executed. The analysis of the calculation results revealed the shortcomings of the studied truss-to-column connection in a frame structure.

Results. As a result of the connection design optimisation, a new configuration was suggested, where the connection of a bottom chord was executed by a slotted gusset plate. Such a solution allows for the most complete use of the bearing capacity of the bottom chord cross section.

Discussion and Conclusion. As a result of the optimisation, the proposed design of a truss-to-column connection makes it possible to reduce the metal consumption while maintaining the relative simplicity of manufacture. At the same time, by reducing the local stresses, it is possible to achieve the greater strength and reliability of a truss-to-column connection.
Political-Legal Means of Ensuring the Institution of Electoral Democracy Development in Russia

Published: July 2024

Introduction. At present, the Russian state is still undergoing the process of its social system transformation. The deterioration of the geopolitical situation has affected all spheres of state activity and has made the political, social and economic contradictions more acute. The electoral (vote-based) democracy is a category both social and political-legal. The institution of elections in the contemporary states becomes the focus of close attention due to capacity to involve a big amount of citizens into the social life. However, the process and final result of citizens' will expression is, to great extent, determined by the electoral system existing in the country. Legal scholars are very careful when referring to the issues of electoral system reform because in the countries with the transitional political systems of the late 20th century, the electoral institutions have developed intensely, but often inconsistently and without proper thinking. The aim of the present research is to reveal the weak points in the political-legal means of ensuring the electoral democracy development in Russia and propose the ways of reinforcing the political and ideological component in the electoral system of the country.

Materials and Methods. The political and legal basis for ensuring the institutional development of electoral democracy in Russia was analysed in the article. The general scientific and specific scientific methods were used in the research, such as, the cognitive analysis of the electoral democracy essence, the analysis of the official legal documents that legally stipulate the categorial apparatus of the object of the research, i.e. electoral democracy, the sociological method of studying the public opinion regarding elections in the country, and others.

Results. It has been proved that further institutionalisation of the vote-based or electoral democracy processes requires legal stipulation of the technological and socio-political innovations. Measures on improving the institution of electoral democracy in accordance with the social request of the Russian people have been proposed.

Discussion and Conclusion. The problems of political and legal ensuring the institute of electoral democracy in the Russian Federation have been revealed. The state policy goals for improving the institution of electoral democracy within the sustainable development of Russia could be achieved through further accomplishment of the system of suffrage, reinforcement of the political and ideological component of the electoral system of the country.

The ownership structure is a crucial aspect of corporate governance and firm value, understanding its implications allows companies to make informed decisions to enhance their value and governance practices. Therefore, this study empirically investigated if ownership structure influences the relationship between corporate governance and firm value. A composite index was developed to evaluate corporate governance, considering board independence, size, diversity, and audit committee independence, while Tobin’s Q was employed to estimate non-financial stock exchange firms’ value. Additionally, ownership structure was defined by three main categories: government ownership, managerial ownership, and foreign ownership. The study utilized a descriptive longitudinal research method to analyze secondary data, employing statistical measures like mean, median, standard deviation, and skewness and conducting a correlation test. Moreover, diagnostic tests were utilized to assess normality, multicollinearity, heteroskedasticity, stationarity, and autocorrelation, determining a random effects model as the most suitable. Correlation was also conducted using Pearson’s coefficient (r) to measure the strength and direction of the linear relationship. The empirical results exhibited that ownership structure moderated the relationship between corporate governance and firm value.
