Authors: Arafa Mostafa A. , Farhat Karim Hamda , Rabah Danny M. , Khan Farrukh K. , Mokhtar Alaa , Al-Taweel Waleed
Published: October 2023

Background:

Prostate cancer screening with prostate-specific antigen (PSA) can result in unnecessary biopsies and overdiagnosis. Alternately, PSA density (PSAD) calculation may help support biopsy decisions; however, evidence of its usefulness is not concrete.

Objective:

To evaluate the predictive value of PSAD for clinically significant prostate cancer detection by systematic and MRI-targeted biopsies.

Methods:

This prospective study was conducted at two tertiary hospitals in Riyadh, Saudi Arabia, between December 2018 and November 2021. Patients suspected of prostate cancer were subjected to multi-parametric MRI, and for those with positive findings, systematic and targeted biopsies were performed. Clinically non-significant and significant prostate cancer cases were classified based on histopathology-defined ISUP grade or Gleason score. The PSAD was measured using the prostate volume determined by the MRI and categorized into ≤0.15, 0.16–0.20, and >0.20 ng/ml2 subgroups.

Results:

Systematic and targeted biopsies were carried out for 284 patients. The discriminant ability of PSAD is higher in MRI-targeted biopsy compared with systematic biopsy (AUC: 0.77 vs. 0.73). The highest sensitivity (97%) and specificity (87%) were detected at 0.07 ng/ml2 in targeted biopsy. More than half of the clinically significant cases were detected in the >0.2 ng/ml2 PSAD category (systematic: 52.4%; targeted: 51.1%). The CHAID methodology found that the probability of having clinically significant cancer (CSC) in patients with PSAD >0.15 ng/ml2 was more than threefold than that in patients with PSAD ≤0.15 ng/ml2 (64% vs. 20.2%). When considered by age, in PSAD ≤0.15 ng/ml2 subgroup, the percentage of CSC detection rate increased from 20.2% to 24.6% in patients aged ≥60 years.

Conclusion:

PSAD has good discriminant power for predicting clinically significant prostate cancer. A cutoff of 0.07 ng/ml2 should be adopted, but should be interpreted with caution and by considering other parameters such as age.
Surgical Consent in the Pediatric Age Group: Parental Perceptions Toward Legal Aspects of Informed Consent
Authors: Essa Madani
Published: October 2023

Background:

The perceptions of parents/legal guardians may drive their decisions on providing informed consent for minors. Currently, no study from Saudi Arabia has assessed the perceptions of parents/legal guardians toward informed consent for pediatric surgical procedures.

Objective:

To determine parents’ perception and understanding of pediatric informed consent for surgeries from Saudi Arabia and determining their level of participation in the decision-making process of the treatment modality.

Methods:

This observational cross-sectional study was conducted among parents from the Jazan region of Saudi Arabia with at least one child aged ≤ 12 years. Three aspects of surgical informed consent were evaluated: parents’ awareness, attitude, and understanding of informed consent and its legal issues; the knowledge they sought during informed consent discussions; and parents’ opinions about their respective roles in the decision-making process for the treatment.

Results:

A total of 366 responses were included in this study. More than 95% of the participants agreed that informed consent was necessary; however, 94.7% felt that regardless of their beliefs, they had to sign the form. Surprisingly, the majority (61%) believed that any relative can sign the consent form on behalf of the parents/legal guardian. Most respondents believe that pre-operative procedures (80.8%), the cost (93.9%), and the reason for the procedure and its alternatives (87.2%) should be discussed when informed consent is being sought. About 76.5% of the participants wanted to know all the information regarding the procedure; of these, 48.3% responded that they would play a role in deciding the eventual treatment modality.

Conclusion:

The findings of this study indicate the need to increase knowledge regarding surgical informed consent among parents in the Jazan region of Saudi Arabia.

О симметризованных критериях типа хи-квадрат в авторегрессии с выбросами в данных
Authors: Boldin Mixail Vasil'evich
Published: October 2023

Мы рассматриваем линейную стационарную модель $\mathrm{AR}(p)$ с неизвестными средним, коэффициентами и функцией распределения инноваций $G(x)$. Наблюдения за авторегрессией содержат грубые ошибки (выбросы, засорения). Распределение засорений $\Pi$ неизвестно, их интенсивность - $\gamma n^{-1/2}$ с неизвестным $\gamma$, $n$ - число наблюдений. Основной задачей (помимо прочих) является проверка гипотезы о нормальности инноваций
$\boldsymbol H_{\Phi}\colon G (x)\in \{\Phi(x/\theta), \theta>0\}$, $\Phi(x)$ - функция распределения $\boldsymbol N(0,1)$. В рассматриваемой ситуации неприменимы тесты, которые строились ранее для авторегрессии с нулевым средним. В качестве альтернативы в этой работе предлагаются специальные симметризованные тесты типа хи-квадрат. Их асимптотическое распределение при гипотезе и $\gamma=0$ свободно. Изучается асимптотическая мощность при локальных альтернативах в виде смеси $G(x)=A_{n,\Phi}(x) :=(1-n^{-1/2})\Phi(x/\theta_0)+n^{-1/2}H(x)$, где $H(x)$ - функция распределения, а $\theta_0^2$ - неизвестная дисперсия инноваций при $\boldsymbol H_{\Phi}$. Устанавливается асимптотическая качественная робастность тестов в терминах равностепенной непрерывности семейства предельных мощностей (как функций $\gamma$, $\Pi$ и $H(x)$) относительно $\gamma$ в точке $\gamma=0$.

Mother to child transmission (MTCT) of human T-cell lymphotropic virus (HTLV)–1 is associated with increased risk of adult T-cell leukemia and can be unrecognized without routine antenatal screening. We assessed the seroprevalence of HTLV-1/2 among pregnant women attending The University Hospital of the West Indies Antenatal Clinic, 2019, and validated a cost-effective strategy to screen antenatal clinic attendees for HTLV-1/2. Residual antenatal samples from 370 women were tested for HTLV-1/2 by chemiluminescence microparticle immunoassay (CMIA). Six samples were confirmed HTLV-1 positive by Western blot (none for HTLV-2) for a prevalence of 1.62%. Four mother–child pairs were able to be recruited for HTLV testing of children, with two children testing HTLV-1/2 positive. Medical records of HTLV-1–infected women revealed that all women breastfed, indicating an unrecognized risk for HTLV MTCT. To assess whether pooling of samples as a cost-reduction strategy could be introduced, we pooled all antenatal samples received between November and December 2021 into 12 pools of eight samples/pool. Two pools were CMIA positive, and de-pooling of samples identified two CMIA-positive samples (one per pool), both confirmed as HTLV-1 by Western blot. These results indicate that HTLV-1 remains prevalent in pregnant Jamaican women and that sample pooling can be a cost-effective strategy to limit MTCT in Jamaica.

Dwellings of the Czartoryski lineage on the eastern frontier of Poland – a subjective take

Until the beginning of the 19th century the Czartoryski family felt at home on the eastern frontier of Poland. This is where their influence was originated and developed; this is where they built their dwellings, castles, Roman and Greek Catholic churches, Orthodox churches and funded schools. Finally, this is where the foundation for the family’s economic power came from. The article is a subjective take on the historical role played by the dwellings of the Czartoryski lineage – Czartorysk, Klewań, Korzec, Czernelica, Międzyboż – as well as the material remains and remnants present in the 21st century in the memory of the local residents. The story, expanded to include the turn of the 20th century, recalls the social activity of Jerzy Czartoryski in the eastern Galicia, as well as the Czartoryski Kazimirs, in the period of the Second Polish Republic in Żurawno and the alabaster manufacture also set up during this period.

Authors: Pezda Janusz
Published: October 2023

“My Emblem was and always will be: The country – its goodness and its will.” A contribution to the history of the Czartoryski family The Czartoryski family, originating from the Gediminas family, is mentioned many times in the history of Poland. It has been present in its history since the beginning of the Polish-Lithuanian union. Its importance grew systematically so that in the 18th and 19th century the Czartoryski family became one of the richest and most influential families in the Polish-Lithuanian Commonwealth. Political connections and friendships gave the opportunity to influence the course of events, while strengthened the position of the family; the growing fortune and income that flowed from it supported these efforts. The characters selected are only examples from among all representatives of the family. They are a testimony that the Czartoryski family has always served, and continues to serve Poland faithfully, both in times of its splendor as well as its decline, supporting with their strength and abilities the efforts for its flourishing and rightful place in Europe.

Matuszewicz family and their relationships with selected representatives of the Czartoryski family

This article presents the relationships of the Czartoryski family with selected representatives of the Matuszewicz family, namely: Marcin Matuszewicz, Tadeusz Matuszewicz and Zofia Matuszewiczówna. The Matuszewiczs, who were middle-class nobility, owed the Czartoryski a lot of favors. Because of the protection of Michał Fryderyk Czartoryski and his nephew Adam Kazimierz Czartoryski, Marcin and Tadeusz had the possibility to start on their paths of political careers. Contrary to Marcin, Tadeusz Matuszewicz was not only a client of the Czartoryski family; over time, he became their trusted household member and friend. His daughter Zofia Matuszewiczówna had a special close relationship with the Czartoryski family. Duchess Izabela Czartoryska treated her as her own daughter, and she wanted to see her as a daughter-in-law.

Published: October 2023

This study addresses the issue of identifying the determinants of the institution of a civic legislative initiative. It aims to present selected legal and factual limitations related to this institution, identified at the level of the regulations of local self‑government systems, and in selected resolutions defining the detailed principles for filing a legislative initiative. The discussion also covers issues related to submitting a draft resolution for an opinion (the stage at which such an opinion should be given) and/or for agreement with other competent authorities (the entity responsible for performing the duty of agreement). The article also looks at matters that, based on specific provisions, cannot be the subject of a civic legislative initiative. It primarily uses an analytical‑dogmatic research method, drawing on monographs and scholarly articles on the studies of administrative law, along with administrative court judgments.
Zmiany w wybranych przepisach ustawy z dnia 4 lutego 2011 r. o opiece nad dziećmi do lat 3 wprowadzone w związku z pandemią COVID-19
Authors: Szeląg Tomasz
Published: October 2023

This article aims to discuss changes in the provisions of the Act of 4 February 2011 on the care of children under the age of 3 introduced in connection with the COVID- 19 pandemic, both in terms of new and amended provisions. The pandemic resulted in the introduction of two completely new provisions to the Act (Articles 6a and 6b). One of these allows the minister competent for family affairs, by way of an ordinance, to temporarily limit or suspend the functioning of forms of care for children aged up to 3 across all or part of the country; the other provides that, if necessary, certain provisions of the Act in relation to all or some forms of care for children under the age of 3 can be excluded by means of an ordinance. However, the most important controversy may be over changes regarding the issue of preventive vaccinations. These are not yet required by law, but nothing stands in the way of such a requirement being introduced; individual institutions running nurseries or children’s clubs already have provisions in their statutes requiring or favouring vaccination of children.
Dostęp do usług świadczonych w ogólnym interesie publicznym w zakresie publicznego transportu zbiorowego w przepisach Unii Europejskiej i prawa krajowego na przykładzie prawa polskiego
Authors: Nodżak Agata
Published: October 2023

Services of general interest in the field of public transport are governed by an extensive system of laws, created by the European Union and national authorities. This is done on the basis of the division of competences between the Union and the Member States, pursuant to Article 4 of the Treaty on the Functioning of the European Union. It is therefore possible, on the one hand, for the Union to make a positive contribution to the development of services of general interest in the field of public transport by creating uniform standards; and, on the other, for the diversity of traditions, structures and situations in the individual Member States to be preserved through the law‑making activities of the national authorities. Using the example of Poland, it may be stated that the legal system relating to the provision of services of general interest in the field of public transport consists of regulations ranging from treaty provisions, through Article 36 of the Charter of Fundamental Rights and EU rules, to statutory regulations and local laws.
The nexus between human security and human rights
Authors: Pavleski Aleksandar
Published: October 2023

The expansion and deepening of security have initiated the emergence of new concepts, which, among other things, have enabled new ways of understanding and interpreting threats and risks in the security sphere. Human security is one of the new concepts that are becoming part of the security strategies of many countries, despite still-present dilemmas, especially over its practical significance and usability. This paper explores the interrelationship between human security and human rights, starting from the reference object towards which both are directed; that is, the individual. On the one hand, it explores the placement and meaning of human rights in the concept of human security, also enabling its greater concretization; on the other, it analyses the meaning and impact this concept has and should have in promoting and protecting human rights. Hence, the main thesis is that the human security concept has a greater chance of being more widely accepted and more effective when based on human rights, and that human rights are more likely to be protected and respected if treated as part of human security.
Ensuring the human rights to a healthy environment: normative regulation and practice of the ECtHR
Authors: Volkova Yulia
Published: October 2023

This article examines the regulatory practice and the practice of the ECtHR in ensuring the right to a healthy environment. At the present stage of humankind, the question of understanding a person as part of an ecosystem is increasingly being raised. In this regard, it is important to emphasize that the current state of international legal regulation of environmental relations strongly indicates the need for serious reforms to international environmental law, primarily in terms of increasing the effectiveness of existing mechanisms for environmental cooperation between states and creating new mechanisms for such cooperation. It has been established that environmental rights are implemented primarily through the formation of international policy and legislation, especially the EU’s strategic position on the environment. This was legally enshrined in the Treaty on the European Community, which declared the EU’s aspirations for a high degree of protection, improving the quality of the environment and people’s standard of living. Over time, this became a starting point for the environmental policy and law of the EU, and then a duty for the implementation of national environmental legislation. It is indicated that the scientific recognition and normative consolidation of environmental rights in international law are important for the development of international ideological concepts of environmental protection, based on the ideas of solving environmental problems in the interests of the individual and all humankind. This is also salient for the formation of a system of international environmental law. A striking example of an international treaty that secures environmental human rights is the Convention of the United Nations Economic Commission for Europe on Access to Information, Public Participation in Decision-​Making and Access to Justice on Environmental Issues, adopted on 25 June 1998, in Aarhus, Denmark (the Aarhus Convention). This identified three main types of environmental rights considered as important factors in the development of democracy: public access to environmental information; public participation in the decision-​making process on environmental issues; public access to justice on environmental issues. These rights are implemented primarily through the formation of international environmental policy and international environmental legislation, especially the EU’s strategic position on the environment. This was legally enshrined in the Treaty on the European Community, which declared the EU’s aspirations for a high degree of protection, improving the quality of the environment and people’s standard of living. Over time, it became a starting point for the environmental policy and law of the EU, and then a duty for the implementation of national environmental legislation.
Verifying an Effect-Handler-Based Define-By-Run Reverse-Mode AD Library
Authors: de Vilhena Paulo Emílio , Pottier François
Published: October 2023

We apply program verification technology to the problem of specifying and
verifying automatic differentiation (AD) algorithms. We focus on define-by-run,
a style of AD where the program that must be differentiated is executed and
monitored by the automatic differentiation algorithm. We begin by asking, "what
is an implementation of AD?" and "what does it mean for an implementation of AD
to be correct?" We answer these questions both at an informal level, in precise
English prose, and at a formal level, using types and logical assertions. After
answering these broad questions, we focus on a specific implementation of AD,
which involves a number of subtle programming-language features, including
dynamically allocated mutable state, first-class functions, and effect
handlers. We present a machine-checked proof, expressed in a modern variant of
Separation Logic, of its correctness. We view this result as an advanced
exercise in program verification, with potential future applications to the
verification of more realistic automatic differentiation systems and of other
software components that exploit delimited-control effects.
The Story of Definite Integrals: A Calculus Textbook Narrative Analysis
Authors: Huffman Hayes Amanda
Published: October 2023

There is a plethora of textbooks to choose from. While most textbooks contain the same content, teachers need to understand the textbook they have chosen to support their students’ learning, as textbooks can significantly impact student learning and teacher instruction. When searching for a way to understand the various textbooks, my research question became, How do calculus textbooks tell the story of definite integrals? My research is in response to the never-ending search for how teachers can select and use their resources. Also, this study contributes to understanding the relationships between stories and knowledge construction using Dietiker’s (2015) narrative framework to analyze the written calculus curriculum. I wrote the specific stories of introducing the definite integral as told by five calculus textbooks. Analyzing how the stories developed disclosed the similarities and differences among the texts in teaching definite integrals. The analysis also revealed a variety of avenues to introduce and teach definite integrals, including a focus on the area under the curve, Riemann sums, or the Fundamental Theorem of Calculus, and some implications to the context of physics related to these avenues. These insights provide teachers with a deeper understanding of textbook lessons and the variances that can potentially alter student learning.
Engineering Praxis Ethos: Designing Experiences to Support Curricular and Instructional Improvement in STEM Education
Authors: Salcedo Oscar H. , Carrejo David J. , Luna Sergio
Published: October 2023

This paper discusses engineering praxis ethos (EPE), a proposed framework for constructing a STEM learning environment embedding interrelated components of learner experience and design activity, which can support curriculum and instructional design and evaluation in STEM education.  The authors propose that STEM is a meta-discipline that relies on the design life cycle, the intellectual root of engineering disciplinary knowledge. The nature of design and design activity calls attention to domain-specific needs of STEM teachers and focuses discussions and critiques about the epistemological adequacy of integrated STEM content knowledge. Given the urgent need for learners to develop 21st century skills in STEM, the authors argue for the feasibility of incorporating both mathematical and simulation models using new technologies when designing experiences for learners.  An example of teaching and learning systems thinking in undergraduate engineering education highlights how EPE can be a viable theory of action for STEM educators.
Scaling up a Technology-Based Literacy Innovation: Evolution of the Teacher Professional Development Course
Authors: Head Jennifer , Lysenko Larysa , Wade Anne , Abrami Philip C.
Published: October 2023

Good teachers are a major predictor of students’ success in school and beyond it. Finding ways to increase the quality of teaching has been a concern for educational systems across various income contexts and, particularly, in the Global South. This paper discusses the iterative design of an online teacher professional development program geared to improving teachers’ English language instruction by means of implementing early literacy software. The program was implemented in various modes (face-to-face, blended and online) with early primary teachers scattered throughout Kenya during the pandemic school closures and after reopening. Relying on the blended learning approach, a potentially effective technology-driven TPD offers multifaceted content, has adaptive and flexible design, and is ongoing until mastery of core concepts is achieved. Further, such solution develops motivational dispositions of teachers about teaching with early literacy software so that its perceived value and the likelihood of success are high, and the benefits outweigh the costs of implementation. The next step of this research is to learn about the specific outcomes of the blended TPD, including changes in literacy instruction and subsequent improvements in student literacy skills.

Objetivo: O presente estudo busca elucidar as influências sociais e de políticas públicas sobre o sofrimento de cuidadoras, a partir de uma perspectiva ético-política. Método: Esta pesquisa é de natureza qualitativa. Foram conduzidas entrevistas semiestruturadas com dez cuidadoras informais. Todas as participantes são mulheres e possuem vínculo familiar com as pessoas das quais cuidam. Os dados coletados foram analisados com base no conceito de sofrimento ético-político. Resultados e Discussão: O sofrimento ético-político de cuidadoras é marcado pela desigualdade de gênero, quando da divisão das tarefas de cuidado. O Estado, que aparece como coadjuvante na execução de suas políticas públicas, ao se desresponsabilizar pelo cuidado à saúde de pacientes domiciliados, impõe às cuidadoras um papel que deveria ser seu. Ainda assim, a subjetividade das participantes floresce em meio à exclusão, sendo perpassada por gratidão, indignação, solidão, esperança e frustrações. Considerações finais: O estudo aponta para a necessidade de criação de políticas públicas que considerem aquilo que as cuidadoras têm a dizer sobre sua situação, as responsabilidades do Estado e o sofrimento ético-político que marca essa categoria.

Industrial production today requires new improved materials to meet market demands, which leads to the production of new materials with improved properties. One kind of response to those requirements is the development of metal matrix composites (MMCs) with the aim of obtaining materials with better properties when compared to conventional metals and alloys. Nowadays, metal matrix nanocomposites (MMnCs) are being increasingly investigated due to the possibility of achieving better machinability, high fracture toughness and improved ductility when compared to conventional composites. Considering the pace of development and the huge perspective of different classes of materials, this research aims to provide insight into the mechanical properties of aluminium nanocomposites. Aluminium nanocomposites are attracting a lot of attention due to their high strength-to-weight ratio, wear resistance and low costs, when compared to matrix alloy. In this paper, an attempt is made to review other research reports and make a connection between the characteristics of the microstructure and the mechanical properties, which are dependent on the method of fabrication and type and content of reinforcement.

Sliding friction is a common tribological effect that occurs between the contact surfaces of the inner components (inner race, outer race and balls) of a spindle rolling bearing during operation. This friction generally generates heat, which can affect the performance of the rolling bearing. To date, numerous studies have assumed that the contact surface between the inner components of the bearing is circular and stationary. While this assumption has yielded adequate results, it is not sufficient in the case of angular contact ball bearings, where the contact surfaces are elliptical and could be treated as either stationary or moving heat sources. This paper presents solutions for both, stationary and moving heat sources for elliptical contact surfaces in a spindle rolling bearing. The primary objective is to find the thermal contact resistances which are dependent on the shape of contact, the loads, the rotational speed and the material properties thereof, applying the mathematical expressions developed by Muzychka and Yovanovich. These expressions were used to calculate various thermal resistances, providing results applicable to the analysis of thermal models in spindle rolling elements. Through finite element analysis (FEA) performed in Ansys Workbench, the stationary and moving heat sources were compared, finding the heat distribution along the elements of the bearing. The findings herein are suitable for the creation of thermal networks in rolling bearings, which are essential to predict their thermal behaviour.

Authors: YENİLMEZEL Simge , ERTUĞRUL İrfan
Published: October 2023

Today, companies that are under intense competition have needed to ensure the flow of information, use and store information effectively with the development of technology. Since these needs are met through IT, the IT sector is becoming increasingly important. The formation of many IT companies in the sector requires investors, lending institutions and shareholders to follow the market. In doing so, it is possible to utilize Multi-Criteria Decision Making (MCDM) methods. By using MCDM methods, it is possible to see and evaluate the changes in the financial performance of different companies in the same sector over the years. In this study, it is aimed to evaluate the financial performance of 8 companies that have gained a place in the IT sector in 2021 under 8 criteria. In this evaluation, the criteria weights were determined by the CILOS method, one of the objective criteria weighting methods, and the ranking of the alternatives was done by the CoCoSo method. As a result of the procedures, the most important criterion is K1 Current Ratio and the company with the best performance among the alternatives is A1 FONET. The fact that the two methods chosen are new methods makes the study original.

Published: October 2023

This study investigated the effects of cognitively challenging with nonlinear pedagogical games on the executive functions and situational interests of students in physical education. Participants were 145 fifth and sixth-grade students (74 boys, 71 girls) from four elementary schools. This acute investigation, which included a physical education session, utilized a quasi-experimental design with four groups, repeated measures, and cross-over. After the post-test, one fifth- and one sixth-grade class from each school was randomly assigned to Group 1 with cognitively challenging nonlinear pedagogy games, Group 2 with a session for teaching soccer skills, Group 3 with a session for teaching track and field skills, and Group 4 control group, all the group with cognitively challenging physical with activity nonlinear pedagogy games. Included were pre- and post-test measures of executive functioning and a post-test assessment of situational interest. Students in Group 1 who engaged in cognitively challenging physical activity with nonlinear pedagogy games increased their executive function scores (t(39) =−19.75, p < 0.001, d=1.82) more than students who participated in sessions with group 2 soccer (t(33) =−3.14, p=0.005), group 3 track and field skills (t(38) =−0.98, p=0.325) and those group 4 the control group (t(32) =−0.68, p=0.523). The positive effects on the executive functions of students were duplicated when the cognitively demanding physical activity with nonlinear pedagogy games session was administered to the control group on the waiting list Students who participated in the soccer skills session showed some improvements in their executive functions. Students who participated in cognitively challenging physical nonlinear games scored higher on novelty than those who participated in soccer or track and field. These findings confirm the efficacy of cognitively challenging physical activity using nonlinear games in stimulating the executive functions of students in physical education.

Archetypes of Sex. Unmasking Algae’s Innocence, the Nathanael Pringsheim Revolution.
Authors: Deutsch Andreas
Published: October 2023

Algae have played a crucial role in shaping our planet’s atmosphere, as they transform CO2 into the oxygen we breathe. They contribute to building a sustainable future by aiding in the fight against climate change, providing new energy sources and essential resources for nutrition. NATHANAEL PRINGSHEIM (1823–1894), a pioneer of modern botany and a contemporary of Charles Darwin, revolutionized the understanding of biology. In his research on algae, Pringsheim revealed that sexuality was a fundamental principle even in organisms previously classified as “lower” life forms. This book offers readers: – exciting insights into the development of modern biology illustrated through Pringsheim’s fascinating life and scientific achievements, – the first-ever account of the Pringsheim family, persecuted in the Third Reich, and their contributions to the natural sciences, – an enthralling narrative of the challenging journey to establish the first German marine biology research station on the island of Helgoland, – an appealing showcase of large-scale artistic interpretations of microscopic worlds, created by Pringsheim, also a master of scientific illustration – and last but not least, new perspectives on algae research, which is more relevant today than ever before.
A transcultural approach: mapping cosmopolitanism in Zadie Smith’s White Teeth (2000)
Authors: Iqbal Maham , Siddique Maryam , Ahmed Arslan
Published: October 2023

This paper aims to probe into the transcultural aspect of White Teeth by Zadie Smith. Under transculturalism, cosmopolitanism is pivotal in transcending ethnographic and cultural borders. Zadie Smith’s avant-garde effort to acknowledge people around the globe about the perks of a communal society is phenomenal. Her novel addresses thematic concerns of immigration, postcolonial conflicts, globalization, multiculturalism, and identity. Previously, her novel was read and discussed as a postcolonial text. However, this research paves the way to re-read it through a liberal lens and delineates the cosmopolitan approach proposed by Kwame Anthony Appiah. The novel invites readers to consider the complexities of living in a world where cultures intersect, clash, and coexist. This article explains the relationship between the main characters in addition to the bildungsroman of the second generation. The generational differences within families highlight the evolving nature of cosmopolitanism as the characters attempt to reconcile their heritage with their present circumstances. Zadie Smith’s technique of inter-narrativity rekindles hope in global citizens to build a transcultural society together. The article directs the audience to see beyond the postcolonial intrusions and accept intercultural changes as challenges needed to move and grow in this era of globalization.

O presente artigo relata a percepção dos alunos dos cursos de engenharia ofertados por um dos campi de uma universidade, cuja sede é localizada no Norte do Paraná, quanto ao aprendizado e oportunidades nas modalidades de ensino presencial e remoto. Para a obtenção dos dados a serem analisados, foi realizado um estudo de caso exploratório e descritivo, com abordagem quantitativo-qualitativa, utilizando como técnica de coleta dos dados a aplicação de um questionário on-line. Concluiu-se que há a tendência por parte dos alunos em apoiar uma proposta de ensino híbrido, visto que aproximadamente 54,6% dos estudantes acreditam que essa modalidade é igual ou superior ao ensino presencial. Isso acontece, dado as vantagens e/ou desvantagens em ambos os tipos de ensino, como mais tempo de estudo no ensino presencial e mais oportunidades de fontes de renda no ensino remoto emergencial, que podem ser balanceados em uma metodologia híbrida. A título comparativo, 80,4% dos alunos acreditam que aprendem mais no ensino presencial, contra 19,6% do ensino remoto.
