Authors: Ren Wenxuan , Wang Rui , Mohamad Syamsul Nor Azlan , Mao Chaojin , Harutyunyan Hasmik
Published: February 2024

In China, there is a thriving trend of utilizing a unique form of blended learning that combines MOOCs (massive open online courses) and SPOC (Small Private Online Course). However, the evaluation methods used for these blended learning courses have not been adequately developed. The objective and accurate evaluation of blended learning poses a challenge. Therefore, it is imperative to conduct a preliminary study to examine the relationships between various factors, such as the quality of the teaching environment, the quality of teachers' offline teaching, the quality of teachers' online teaching, and their impacts on students' learning satisfaction and learning outcomes in a blended learning setting. This study aims to analyze the factors in blended learning by employing structural equation modeling and interviews with 275 students. The findings of this research contribute to the advancement of student learning evaluation in blended learning by incorporating the evaluation of the teaching environment, the quality of teachers' online teaching, the quality of teachers' offline teaching, student satisfaction, and students' learning outcomes. Furthermore, this study offers a comprehensive analysis of the influence of the teaching environment on the aforementioned factors in blended learning, thereby providing a rationale and robust empirical evidence for the Chinese government's sustained investment in information technology infrastructure in higher education.
¿Giro a la izquierda? Nuevos gobiernos en América Latina
Authors: Cantamutto Francisco J.
Published: February 2024

El presente trabajo problematiza la idea de un reciente “giro a la izquierda” de los gobiernos de la región. Sin menospreciar los cambios efectivos que el nuevo siglo ha traído, entendemos que la caracterización de estos gobiernos como de izquierda es inadecuada: existen diversas limitaciones para diferenciarse de otros tipos de gobiernos contemporáneos. Para dar cuenta de esta idea se revisan criterios establecidos por la literatura sobre el tema y se analizan algunos indicadores económicos. Se proponen, además, distinciones entre los gobiernos considerados de izquierda.
Efectos de la resolución del contrato por incumplimiento: restituciones e indemnización por daños en una perspectiva de comparación dentro de la latinidad jurídica
Authors: Nicolussi Andrea , Troncoso María Isabel
Published: February 2024

El ensayo aborda las restituciones derivadas de la resolución por incumplimiento en un horizonte comparativo dentro de la latinidad jurídica. En particular, se comparan las soluciones aceptadas en el derecho italiano (latinidad jurídica europea), y las de dos ordenamientos latinoamericanos, Colombia y Perú. Desde el punto de vista de la disciplina dedicada a la resolución y sus consecuencias, los códigos italiano y peruano son los más avanzados, mientras que el colombiano, que data del siglo XIX, deja un amplio espacio al desarrollo jurisprudencial de la figura. En cualquier caso, los tres ordenamientos parecen converger en la función de las restituciones como herramienta para devolver a las partes a la situación económica anterior al contrato. Sin embargo, en lo que respecta al fundamento de la función restitutiva, persisten las incertidumbres entre la repetición de lo indebido y devoluciones específicamente reguladas por la resolución. Incluso el vínculo recíproco entre las restituciones debidas por ambas partes sigue siendo poco profundizado. Finalmente, la coordinación entre restituciones e indemnización de daños y perjuicios en el marco de la resolución parece captada más claramente en la doctrina italiana, a la que la peruana parece más cercana. La indemnización de daños y perjuicios tiene que ser compatible con el hecho de que la parte cumplida del contrato ya no debe su observancia al mismo, y además de renuncia también a la contraprestación. La indemnización, por tanto, no puede incluir el valor de la prestación incumplida, sino que debe proteger a la parte fiel al contrato en lo que respecta a su interés positivo en el mismo, es decir, en el beneficio que le habría aportado la prestación debida por la parte que incumplió.
El control del contenido en contratos estandarizados. Análisis de la prohibición de cláusulas abusivas bajo el artículo 1399 del Código Civil peruano
Authors: Vásquez Rebaza Walter Humberto
Published: February 2024

Una de las formas más importantes –y controvertidas– en que el legislador interviene en contratos estandarizados (es decir, contratos con cláusulas generales de contratación y contratos de adhesión) reside en la posibilidad de que las autoridades jurisdiccionales controlen su contenido negocial con el fin de eliminar o sustituir cláusulas efectivamente incorporadas en aquellos, por ser abusivas o vejatorias. En el presente trabajo, se examina la disciplina de control del contenido dispuesta por el artículo 1399 del Código Civil, norma que, pese a haber sido injustamente relegada por los estudiosos nacionales, cuenta con un enorme potencial para –correctamente entendida– lograr los propósitos de tutela fijados por nuestro Código Sustantivo.Con ocasión a ello, se analizará, en primer lugar, las diversas normas jurídicas contenidas en el artículo 1399, así como sus respectivas hipótesis y consecuencias. El referido análisis será complementado por una aplicación práctica a casos concretos, lo que permitirá comprender el funcionamiento del dispositivo normativo. En segundo lugar, se reparará en el fundamento e importancia del artículo en mención, así como su potencialidad para convertirse en una noción capaz de erradicar estipulaciones disfuncionales más allá de la escueta nómina consagrada por el legislador peruano de 1984 en el artículo 1398. En tercer y último lugar se desarrollará cuáles son las circunstancias justificadoras capaces de neutralizar, en cada caso concreto, el carácter abstractamente vejatorio de una cláusula presuntamente abusiva bajo el artículo 1399. Este análisis cobra especial relevancia pues su tratamiento por los estudiosos nacionales ha sido casi inexistente.

Sendo a transação instrumento jurídico de grande importância prática e teórica, cuja finalidade precípua reside em servir para a regulação de conflitos entre particulares, mediante as concessões recíprocas, reputa-se necessário destacar e examinar suas particularidades, no quadro dos contratos e verificar o desenvolvimento dado a ela pela jurisprudência nos vinte anos de vigência do Código civil de 2002. Além disso, cumpre destacar a nova posição atribuída à transação pelo novo Código de Processo Civil brasileiro, de 2015.
La Protección al Consumidor en las Estructuras Negociales Contemporáneas: a Propósito de la Conexidad Contractual en los Contratos de Consumo
Authors: Frustagli Sandra A.
Published: February 2024

El trabajo analiza las consecuencias jurídicas de la conexidad contractual en los contratos de consumo desde la perspectiva del ordenamiento jurídico argentino. Se toma en consideración que el Código Civil y Comercial dispone un régimen normativo propio para el contrato de consumo como categoría negocial diferente del contrato paritario. Sin embargo, dado que las normas que rigen la conexidad contractual se ubican metodológicamente dentro de la teoría general del contrato, la aplicación de ese régimen a los contratos de consumo conexos debe hacerse a la luz del principio pro consumidor, de jerarquía constitucional (artículo 42 de la Constitución Nacional), a fin de garantizar el derecho fundamental a la protección de sus intereses económicos. Esto conduce a reconocer un régimen de acciones en favor del consumidor que resulta más amplio que el emergente de los artículos 1073 a 1075 del Código Civil y Comercial para los contratos conexos en general.

Published: February 2024

Technology has been the main driver for the financial sector. Fintech tools emerged to support the provision of financial services, especially Robo-Advisors (RAs), which allow the automation of the investment management process. The main functions are the creation of an investment portfolio and allocating assets, and daily management of investment portfolios based on a machine learning algorithm. This paper presents a literature review to summarise the importance of RAs in the financial sectors as well as the perception of investors. Also, this literature review presents the main algorithm’s characteristics behind the intelligence of RAs and the primary concerns. The Scopus and Web of Science databases revealed 114 research papers. It was found that investor acceptance of these technologies is affected by aspects of high volatility, which includes financial markets. The algorithm's mathematical models and system architecture might be improved so that this instrument can better suit the needs of investors.

Authors: Pratas Joaquim , Amorim Carla , Reis José Luís
Published: February 2024

Smart retailing technologies are transforming retailers’ operations, consumer shopping experiences, and perceptions about retailers. These technologies are becoming increasingly numerous and may have different interfaces and ways of implementation. Based on the literature review, this study develops a framework to measure the impacts of implementing non-store-based and store-based smart retailing technology pilot projects, with appropriate metrics based on brand leadership, market performance and word-of-mouth. The proposed method is based on a survey distributed to a sample of customers and control groups, using an experimental Latin square design that controls the effects of extraneous variables. With this methodology, different interfaces can be evaluated in the non-store-based pilot projects, and different locations in the store-based pilot projects implementation, controlling extraneous variables such as seasonality, customer profiles and store-specific characteristics. Finally, the academic and managerial contributions to retailers, consumers and technology companies are highlighted, as well as limitations and avenues for future research.

Authors: Ribeiro Diana , Varajão João
Published: February 2024

Information Systems professionals deal daily with ethical dilemmas, which are most notorious when making decisions. Due to the importance of ethical behavior and to prevent unethical situations without full awareness of them, the development of codes of ethics and conduct for companies and communities of professionals has been fundamental. Since the creation of the first code of ethics in computing in 1972, many codes of ethics and conduct have emerged from the initiative of various societies, organizations, and associations all over the world. This article identifies and describes the structural evolution of the main codes in the Information Systems area, from the original to the most recent versions. From analyzing the codes, the following results were obtained: (1) codes of ethics and codes of conduct are the most common code types; (2) the codes are directed mainly at all members of the entities (without differentiation); (3) the evolution of codes is related to the changing of descriptions of conducts, the changing of the structure of documents, and in many cases there is an increase of the number of conducts of ethical behavior in the newer versions of the codes.
Towards an Agile Information Systems Development Process Model
Authors: Meneses Beatriz , Varajão João
Published: February 2024

Process models are fundamental for structuring Information Systems Development (ISD) endeavors and contribute significantly to ISD projects’ efficiency and effectiveness. On the one hand, agile process models have been increasingly adopted in software development. In general, the agile approach emerged to overcome the limitations of the classical models, such as the late delivery of products or the lack of response to changes. On the other hand, regarding ISD, as far as we know, there are no specific proposals for agile processes. Considering the socio-technical nature of ISD, agile processes cannot be adopted in this context without being adequately tailored. This paper describes an ISD agile process model, underlying principles, and activities. It also discusses the model’s practical feasibility, benefits, and limitations.

Published: February 2024

Most car manufacturers are increasingly looking to invest in autonomous driving technology, incorporating driver assistance functions with the aim of improving the safety of their products. Even though more and more vehicles are equipped with driver-assistance technologies, the idea of the vehicle itself performing the driving function completely makes most drivers fearful. A study was therefore carried out, applied to the Portuguese context, with the aim of studying the acceptance of this technology. An explanatory model was used, which incorporates dimensions from the technology acceptance model (TAM) and the main factors that contribute to technology acceptance were also identified. The results contribute to understanding the determinants of autonomous driving technology adoption.

Exploring the Components of Digital Identity on Social Networks Sites: Identifier, Post, Profile Photo, and Selfie
Authors: Reda El Yazidi
Published: February 2024

The digital age has ushered in a paradigm shift in self-expression and identity construction, with social network sites (SNSs) serving as vibrant canvases for individuals to shape and project their digital personality. This paper focuses on delving into the intricate components of digital identity on SNS, focusing on four key elements: identifiers, posts, profile photos, and selfies. Based on a descriptive and analytical method, this article attempts to draw up a detailed and nuanced analysis of the multiple facets of digital identity, thus providing a solid basis for in-depth understanding of this complex phenomenon in the specific context of social networks which technically regulate the representation of self. The results obtained show that the construction of a digital identity is framed by the architecture of SNSs, which incite users to manifest their selves, thus producing unlimited digital traces that reflect their personality traits. The results also provide an understanding of the structure of SNSs that aim to raise awareness of presenting a positive self-image in the digital world.

El sexo, la edad y la modalidad de enseñanza (presencial o virtual) no inciden de manera diferenciada en el uso de las herramientas de aprendizaje activo. Se puede afirmar que, al estar de acuerdo en la implementación de las herramientas de aprendizaje activo, los docentes consideran apropiado este enfoque pedagógico.

 

Active learning is an educational approach that involves the active and direct participation of students in their learning process. The objective of the research was to analyze the role of active learning in higher education as a pedagogical approach of the faculty members of the Facultad de Contaduría y Administración de la Universidad Autónoma de Chihuahua. The research method was analytical-synthetic, involving fieldwork with bibliographic support and using a probabilistic random sampling. The evaluated variable was active learning in higher education from a pedagogical perspective. The main results indicate that teachers with more seniority use active learning tools, mainly teamwork, problem-based learning, project-based learning, as well as online learning and virtual platforms. Younger and contractor teachers also use challenge-based learning, but they give less importance to teamwork. Gender, age, and the mode of teaching (in-person or virtual) do not have a differentiated impact on the use of active learning tools. It can be affirmed that, by agreeing on the implementation of active learning tools, teachers consider this pedagogical approach appropriate.

The finding of this study is vital to business entities in the extension of mobile marketing coverage together with rural consumers to improve the way of life in the current mobile phone era. The Implications and limitations of the research were discussed.
“What’s COVID-19 Vaccine Like?” – From A Cognitive Frame to A Similative Proposition
Authors: Guliashvili Nino
Published: February 2024

Frames and propositions are supposed to be cognitive acts that play a significant role in the perception of reality and the enactment of discursive practices. The linguistic scrutiny of the Covid-19 pandemic discourse could shed light on how the figurative language, similes in particular, are conceptualized by the cognitive structures and represented discursively as surface-level manifestations of the pandemic reality. Thus, the present research is concerned with the analysis of discursive as well as cognitive structures of the figurative language to delineate on relevant theoretical stances. To scrutinize how similes work on a discursive dimension, a discourse analysis is applied, which qualitatively characterizes the concordance lists of the target lingual units obtained from The Coronavirus Corpus https://www.english-corpora.org/corona/. As for the investigation of the cognitive basis of similes, source and target entities/ concepts are identified to focus on the propositional structures. The paper argues that similes as opposed to metaphors explicitly expound propositions and communicative frames in the discourse to avoid incipient cognitive ambiguity of the comparison. The two-fold cognitive shift is evident, which morphs a cognitive proposition into a textual one and lessens the exact sameness. Moreover, discursive elaboration of a simile as a short explanatory phrase transforms into a mini explanatory narrative to provide rational for the novel source concepts of comparison (i.e., computer software, technology, and adventure), which could be rather complex for the human mind to perceive. As it appears, similes may come forward as more tangible cognitive-discursive structures that assist the human mind to cope with novel cognitive comparisons.

Revisiting the Formation and Radicalisation of Boko Haram and Al-Qaeda in the Lands of the Islamic Maghreb (AQIM) through Social Movement Theory
Authors: Danguguwa Kabiru Ibrahim , Hotoro Bello Adamu , Kabara Bello Sani
Published: February 2024

This paper uses social movement theory to examine the rise and development of Boko Haram and AQIM into radical groups. Boko Haram and AQIM were initially established as moderate and conservative Islamist groups in Nigeria and Algeria respectively. AQIM was originally a political party – the FIS but changed names to the GIA, the GSPC, and AQIM each with a different modus operandi. Boko Haram was a local organization that has been espousing an anti-system frame alongside violent tactics since 2009. Relying on secondary data, this paper found that the emergence and eventual transformation of Boko Haram and AQIM into radical movements signify the existence of social movement factors of political opportunity structures, mobilizing structures, and framing processes in Nigeria and Algeria. Results from content analysis of the data show that while the two movements emerged in two distinct socio-economic and political environments, they were rational actors who continued to utilize the available political structures opportunity, mobilizing structures and framing processes to mobilize and sustain collective actions. It is evident that government repression only made the two groups change tactics and strategies when what they regarded as free spaces diminished at times they gathered material and non-material resources. That coincided with the radical views of some of the groups’ members, the presence of mobilizing structures, and a frame resonance that ensured recruitment into the two movements.
E-tax System Adoption and Tax Compliance in Ethiopia: Large and Medium Taxpayers’ Experience
Authors: Yimam Seid , Lidetu Kebede , Belete Tihtina
Published: February 2024

In the last decade, tax administrations in developing countries have been introducing technological innovations such as e-filing and e-payment platforms. The main aim of introducing these technologies is to improve tax compliance and boost revenue collection by increasing convenience and flexibility for taxpayers and reducing their compliance costs. E-filing and e-payment could save taxpayers time preparing and returning taxes and reduce errors and opportunities for corruption. However, the adoption of these technologies and their effectiveness in improving tax compliance could be undermined by several factors. Using tax administrative records, we examined the adoption rate trend of the e-filing system and the correlation between e-filing adoption and tax compliance of large and medium taxpayers in Ethiopia. The timeliness of value-added tax (VAT) and corporate income tax (CIT) return filing and the amount of tax declared are the two main compliance indicators used in this study. Furthermore, we explored the existing challenges and the way forward to improve the adoption of the e-tax system using focus group discussions (FGDs).

Published: February 2024

Rheumatoid arthritis (RA) is a systemic inflammatory disease affecting mainly small and major joints. The development for new drugs for the treatment of RAs is constantly underway, while the purposeful synthesis of multi-targeted small molecules can be considered a promising direction for the synthesis of new anti-rheumatic drugs.

The aim. To evaluate the anti-inflammatory and antiresorptive effects of acyl substituted chromone derivatives in experimental animal model for rheumatoid arthritis.

Materials and methods. RА was modeled in rats by injection of a suspension of human type II collagen and a complete Freunds adjuvant (in a ratio of 1:1) under plantar aponeurosis of the hind limb of the animal. The analyzed substances under ciphers X3A7 and X3A9 at a dose of 20 mg/kg and the reference drug dexamethasone at a dose of 3 mg/kg were administered intraperitoneally for 28 days from the moment of RA modeling. On the 7th, 14th, 21st and 28th days of the experiment, the severity of the clinical manifestations of RA was determined. After 28 days, changes in the content of cytokines in the rats blood serum were assessed: tumor necrosis factor-α (TNF-α), interleukins (IL-1, IL-6, IL-10 and IL-12). Changes of myeloperoxidase activity and concentrations of matrix metalloproteinases (MMPs) of type 2 and 9 were determined in synovial tissues.

Results. During the study, it was shown that the use of the tested compounds X3A7 and X3A9, as well as the reference, contributed to a decrease in the severity of clinical manifestations of RA, starting from the 14th day of the experiment. Subsequently, it was demonstrated that in animals treated with dexamethasone, the cytokine content in blood serum decreased in relation to untreated animals: TNF-α – by 57.8% (p <0.05), IL-1 – 64.1% (p <0.05), IL-6 – 59.1% (p <0.05) and IL-12 – 72.3% (p <0.05), with an increase in the level of IL-10 – by 75.4% (p <0.05). The cytokine profile of the blood serum changed similarly when the studied compounds were administered to animals. It worth be noting that against the background of the administration of dexamethasone, X3A7 and X3A9 substances, the activity of myeloperoxidase decreased by 41.7 (p <0.05), 61.7 (p <0.05) and 65.0% (p <0.05), respectively, while the concentration of MMP2 decreased by 24.0 (p <0.05), 38.5 (p <0.05) and 34.4% (p <0.05), respectively, and MMP9 – by 13.5 (p <0.05), 37.9 (p <0.05) and 35.6% (p <0.05).

Conclusion. The study showed that the administration of the analyzed chromone derivatives X3A7 and X3A9 suppresses inflammatory reactions and resorptive processes in synovial tissues, which can serve as a basis for their further study as antirheumatic agents.

Terrestrial isopods are generally considered as detritivore invertebrates, but in recent years and in different parts of the world they seem to become potential agricultural pests for different crops. The crops affected so far have been mainly arable crops, but damages to few horticultural crops were also documented. Until now, no referenced problems with isopods as crop pests had ever occurred in Italy. In March/April 2023 on two organic farms in northern Italy newly transplanted seedlings of smooth melon in greenhouses were damaged by isopods. Among farms, the loss was estimated between 40% and 50% of the seedlings. The isopod that caused the damage was identified as Armadillidium arcangelii, and, until now, the species had never been reported as a crop pest.

A kereskedelmi hálózatok vizsgálata a mai napig nagyon széles körben kutatott téma. Közgazdászok, hálózatkutatók vizsgálják egy-egy termékcsoport kereskedelmi hálózatainak dinamikáját. Ugyanakkor ahhoz, hogy megértsük, hogy a sokkok, a válságok vagy a technológiai változások hogyan hatnak a termékek kereskedelmére, ezen keresztül pedig a kereskedelmi hálózatokra, elengedhetetlen a hálózati mutatók mintázatainak és összefüggéseinek idősoros vizsgálata, amellyel eddig kevésbé foglalkoztak. Ez a kutatás a kereskedelmi hálózatok időbeli dinamikáját vizsgálja több módszertani megközelítés ötvözésével, ami magában foglalja a hálózat- és klaszterelemzéseket, valamint az oksági vizsgálatokat. Tanulmányunkban olyan módszereket javaslunk, amelyek meghatározzák a különböző termékek kereskedelmi hálózati, strukturális mutatóinak mintázatait, azok válságokra, sokkokra vonatkozó változásait, ok-okozati összefüggéseit. Az eredményeink azt mutatják, hogy a legtöbb termékkategória kereskedelmi hálózata viszonylag kis késéssel, egyformán reagál a sokkokra és a technológiai változásokra, függetlenül attól, hogy nyersanyagokról vagy feldolgozott termékekről van szó. Kutatásunk rámutat, hogy a 2008-as pénzügyi válság nem változtatta meg a reáliák kereskedési hálózatát, azonban a Covid19-járvány kitörése előtt a kereskedelmi hálózatok sérülékenyebbek, koncentráltabbak lettek, így a pandémia és a későbbi háborús konfliktusok egy sebezhetőbb kereskedelmi hálózaton sokkal erőteljesebben fejthették ki negatív hatásaikat. Ennek eredményeképpen közvetve jobban megérezhettük a válság hatását, amely az ellátási láncokat is érintette.

Los derechos de las personas LGTBI en los países del Norte de Europa
Authors: Santamaría Lambás Fernando
Published: February 2024

Los derechos de las personas LGTBI están de actualidad en la sociedad del si- glo XXI. Es nuestro propósito estudiar las normas sobre orientación sexual e identidad de género en los países del Norte de Europa (Reino Unido, Irlanda, Islandia, Finlandia, Dinamarca, Noruega, Suecia, Estonia, Letonia y Lituania). Nos dedicaremos sobre todo al estudio del grado de reconocimiento del derecho al cambio de género en las leyes nacionales, así como si esas legislaciones res- petan o no el Convenio Europeo de Derechos Humanos y la legislación de la Unión Europea, a través de las resoluciones del Tribunal Derechos Humanos y del Tribunal de Justicia de la Unión Europea.

Time-domain instability mechanism for artificial boundary condition of semi-infinite medium described by discrete rational approximation
Authors: Tang Zhenyun , Fu Boxin , Li Xin
Published: February 2024

The use of discrete rational approximation functions to represent foundation dynamic impedance plays a crucial role in the time-domain analysis of soil-structure interaction regarding artificial boundary. In modeling, the rational approximation functions need to be transformed into time-domain recursive models for incorporation into time-history analysis. However, this method also suffers from uncertainties in parameter identification and instability in time-domain analysis when the time-domain recursive models of soil are coupled with upper structure. The stability issue in artificial boundary coupled time-domain computation has not been effectively addressed. This paper establishes the closed-loop transfer function of the coupled system and analyzes the causes of instability in the coupled system based on gain margin analysis. Different numerical simulations demonstrate that the major cause of artificial boundary system instability is the description errors of discrete rational approximation functions beyond the fitting frequency range.
Expert Opinion on the Use of Oral Antibiotics with A Special Focus on Amoxicillin-Clavulanate and Cefuroxime for the Management of Respiratory Tract Infections and Otitis Media in Indian Settings
Authors: Suresh Manjula , Kumar M. Krishna
Published: February 2024

Respiratory tract infections (RTIs) are a major public health concern due to their high morbidity and mortality rates, and widespread distribution. Studies regarding the expert opinion on current practices, clinical observations, and experiences related to the use of oral antibiotics primarily, amoxicillin-clavulanate and cefuroxime for managing respiratory tract infections (RTIs) and otitis media in Indian settings were scarce. So, a cross-sectional, questionnaire based study was conducted to collect opinion among physicians involved in treating RTIs and otitis media across India between June 2022 and December 2022. It was observed that managing upper respiratory tract infections (URTI), majority of the experts (94.1%) preferred amoxicillin + clavulanic acid over other oral antibiotics, such as cefpodoxime, cefixime, azithromycin, cefuroxime, and cefuroxime + clavulanic acid. Furthermore, 91% of the experts opined that amoxicillin with clavulanic acid was better for URTI than other antibiotics and 88% of the respondents preferred to prescribe amoxicillin with clavulanic acid in managing acute otitis media. Additionally, majority of the clinicians (81%) reported that cefuroxime was the most commonly used oral antibiotic for managing lower respiratory tract infections (LRTIs). Nearly 62% of clinicians opined that cefuroxime has better tissue penetration compared to other broad-spectrum antibiotics. Thus, it was found that experts recommended a combination of amoxicillin with clavulanic acid and cefuroxime for the treatment of RTIs. Amoxicillin with clavulanic acid was the preferred choice for managing URTIs and acute otitis media in children, while cefuroxime was favored for lower LRTIs due to its superior tissue penetration and broad-spectrum antibiotic properties.
