Published: July 2024

The ability of mechanical deformation and adaptive shape locking exerts in bulk crystals would offer great promise for ferroelectrics to enable emerging and exciting applications. However, conventional ferroelectric crystals generally suffer from poorly mechanical properties, inherent brittleness and easy to fracture. Here, by implementing fluorination on negative dipoles, we successfully designed a flexible organic ferroelectric phenylethylammonium trifluoromethanesulfonate (PEA-TFMS) capable of shape-changing and locking with outstanding mechanical deformability in its bulk crystals. To our knowledge, it is the first observation since the discovery of organic ferroelectric crystal triglycine sulfate in 1956. Compared to parent PEA-MS (phenylethylammonium mesylate), fluorination subtly alters ionic orientation and interactions to reorganize dipole arrangement, which not only bring switchable spontaneous polarization but also endow PEA-TFMS crystal with directly macroscopical bent and spiral deformability, making it competitive candidates for flexible and wearable devices. Our work will bring inspiration for obtaining mechanically deformable organic ferroelectric crystals toward flexible electronics.

Published: July 2024

The cloning of disease resistance genes in wheat has been disproportionately slow, tedious and costly because of the large and complex genome. Wheat gene cloning projects in the late 1990s and early 2000s were multi-year endeavors, often spanning a decade or longer. The development of genomics-assisted gene cloning tools and speed breeding have significantly accelerated gene cloning in wheat over the past years. Here, we present an optimized, high-throughput disease resistance gene cloning workflow that allows to identify candidate genes in less than six months. As a proof-of-principle, we cloned the stem rust resistance gene Sr6, which has been a historically relevant source of resistance to confine a major stem rust outbreak in North America in the mid-20th century. Sr6 encodes a BED-domain-containing nucleotide-binding and leucine-rich repeat (NLR) immune receptor. Our work exemplifies the progress in wheat disease resistance gene cloning. The workflow described here provides a basis to tackle the systematic cloning of all the genetically described disease resistance genes by the wheat community, which will allow knowledge-guided deployment of resistance genes in wheat breeding.

The wheat stem rust pathogen, Puccinia graminis f. sp. tritici (Pgt), has caused devastating crop losses worldwide. Several stem rust resistance (Sr) genes display temperature-dependent immune responses. Sr6-mediated resistance is enhanced at lower temperatures whereas Sr13 and Sr21 resistances are enhanced at higher temperatures. Here we report cloning of Sr6 by mutagenesis and resistance gene enrichment and sequencing (MutRenSeq), showing it to encode an NLR protein with an integrated BED domain. Sr6 temperature sensitivity was also transferred to wheat plants transformed with the Sr6 transgene. Differential gene expression analysis using near-isogenic wheat lines inoculated with Pgt at varying temperatures revealed that genes upregulated in the low-temperature-effective Sr6 response differed significantly from those upregulated in the high-temperature-effective responses associated with Sr13 and Sr21. Understanding the molecular mechanisms and pathways involved in temperature sensitivity can inform future strategies for deployment and engineering of genetic resistance in response to a changing climate.

Modern rose (Rosa hybrida) is a recently formed interspecific hybrid and has become one of the most important and widely cultivated ornamentals. Here, we report the haplotype-resolved chromosome-scale genome assembly of the tetraploid R. hybrida ‘Samantha®’ (‘JACmantha’) and a genome variation map of 233 Rosa accessions involving various wild species, and old and modern cultivars. Homologous chromosomes of ‘Samantha®’ exhibit frequent homoeologous exchanges. Population genomic and genomic composition analyses reveal the contributions of wild Rosa species to modern roses and highlight that R. odorata and its derived cultivars are important contributors to modern roses, much like R. chinensis ‘Old Blush’. Furthermore, selective sweeps during modern rose breeding associated with major agronomic traits, including continuous and recurrent flowering, double flower, flower senescence, and disease resistance, are identified. This study provides insights into the genetic basis of modern rose origin and breeding history and offers unprecedented genomic resources for rose improvement.

This study aims to comprehensively investigate the role of various environmental and lifestyle factors—including obesity, diet, physical inactivity, urbanization, socioeconomic status, sleep patterns, stress, environmental pollutants, gut microbiota, smoking, and alcohol consumption—in the pathogenesis of Type 2 diabetes mellitus (T2DM).
Background:
Type 2 diabetes mellitus (T2DM) is a global health challenge influenced by genetics, environment, and lifestyle. Key factors affecting T2DM include obesity, unhealthy diet, physical inactivity, urbanization, socioeconomic status, sleep patterns, stress, environmental pollutants, gut microbiota, smoking, and alcohol consumption. Understanding these factors' roles in insulin resistance, beta-cell dysfunction, glucotoxicity, lipotoxicity, and inflammation is crucial for effective prevention and management.
Methods:
A comprehensive search of databases such as PubMed, MEDLINE, Google Scholar, and various journals was conducted without date restrictions. The studies were systematically reviewed to explore the mechanistic links between environmental factors and T2DM pathophysiology. The study adhered to PRISMA guidelines.
Results:
The study revealed diverse associations between environmental and lifestyle factors and T2DM pathogenesis. Obesity was identified as a central contributor, promoting insulin resistance and adipose tissue dysfunction. Unhealthy diets increased T2DM risk through glucotoxicity and lipotoxicity. Sedentary behavior and urbanization compounded these effects. Socioeconomic disparities influenced T2DM prevalence, with lower SES individuals at higher risk. Sleep patterns, stress, environmental pollutants, and gut microbiota composition significantly affected T2DM development. Smoking and alcohol consumption were linked to increased insulin resistance and beta-cell dysfunction. These findings highlight the multifactorial nature of T2DM and the importance of addressing diverse environmental and lifestyle factors for effective prevention and management strategies.
Conclusion:
Obesity, diet, physical inactivity, urbanization, socioeconomic status, sleep patterns, stress, environmental pollutants, gut microbiota, smoking, and alcohol consumption collectively influence insulin resistance, beta-cell dysfunction, glucotoxicity, lipotoxicity, and inflammation in T2DM. Addressing these factors is essential for prevention and management. Promoting healthy lifestyles, improving healthcare access, and mitigating environmental exposures can reduce risk and improve outcomes. Understanding the interplay of these factors provides insights into T2DM's complex nature and informs comprehensive strategies for its prevention and treatment.

Published: July 2024

Cardiac fibrosis after Myocardial Infarction (MI) constitutes the formation of the fibrous scar as part of the wound healing reparative process in the tissue. This scar is essential for replacing the damaged myocardium, and thus preventing the risk of ventricular wall rupture. Nevertheless, scarring may turn excessive by expanding in areas remote to the infarction, causing undesired morphology changes. The increased ventricular stiffness and altered chamber compliance impair cardiac output, and eventually lead to heart failure. Periostin has been marked as a source of interest for its involvement in MI-induced fibrosis. Produced by activated fibroblasts (the scar-forming cells), periostin was found positively correlated with increasing levels of collagen in the myocardium, and upregulated in mouse models of fibrosis-associated-hypertrophic cardiomyopathy. Our study aimed to show that periostin can be used not only as a therapeutic goal itself (for the regulation of post-MI fibrosis), but also as the strategical intermediate to target the activated fibroblasts (prior to inducing therapeutics). Here we show that the conjugation of anti-periostin antibody (AB) to short interfering RNA (siRNA)-based-nanoparticles (NPs) is a feasible and effective practice for this purpose. Produced by the covalent binding of AB to AlgS and the electrostatic interactions between AlgS and siRNA with Ca2+, the NPs presented physical features suitable for in-vivo administration. Their capacity to reach cardiac activated fibroblasts in MI-induced mice was governed by the insertion of AB to their surface, enabling to specify gene therapy against periostin to these cells in particular. Importantly, the delivery of NPs with siRNA against periostin resulted in periostin reduction within the infarction, testifying to the potential therapeutic benefit of the targeting NPs, to be further studied.

Published: July 2024

Functional analysis is the gold standard for assessing challenging behaviors in Applied Behavior Analysis (ABA), particularly important for neurodivergent populations such as individuals with autism. Despite its efficacy, functional analysis needs to be more utilized due to its complexity, time demands, and potential to evoke dangerous behaviors. The Interview-Informed Synthesized Contingency Analysis (IISCA) addresses these issues by offering a faster, less traumatic alternative requiring fewer challenging behaviors. This study aimed to teach IISCA to professionals working with autistic individuals through an asynchronous online training program using Behavioral Skills Training (BST). Thirty professionals participated in theoretical instruction, modeling, rehearsal, and feedback via Google Classroom. Results showed significant improvement, with correct responses increasing from 52% pre-intervention to 82% post-intervention. After multiple attempts, most participants successfully applied IISCA with clients, underscoring the need for iterative learning and feedback. This study demonstrates the efficacy of asynchronous online training in teaching IISCA, providing a flexible, accessible method for training professionals, especially in remote or underserved areas. Future research should explore integrating synchronous elements to enhance learning and investigate the long-term impact on client outcomes.
Smoothly vanishing density in the contact process by an interplay of disorder and long-distance dispersal
Authors: Juhász Róbert , Kovács István A.
Published: July 2024

Realistic modeling of ecological population dynamics requires spatially explicit descriptions that can take into account spatial heterogeneity as well as long-distance dispersal. Here, we present Monte Carlo simulations and numerical renormalization group results for the paradigmatic model, the contact process, in the combined presence of these factors in both one and two-dimensional systems. Our results confirm our analytic arguments stating that the density vanishes smoothly at the extinction threshold, in a way characteristic of infinite-order transitions. This extremely smooth vanishing of the global density entails an enhanced exposure of the population to extinction events. At the same time, a reverse order parameter, the local persistence displays a discontinuity characteristic of mixed-order transitions, as it approaches a non-universal critical value algebraically with an exponent \beta_p'<1βp′<1.
Circular economy awareness, adoption, and its effects on business performance in Saudi Arabia
Authors: Akinwale Yusuf
Published: July 2024

A circular economy has become an innovative business model, though contentious, to replace a linear economy in achieving sustainable and efficient production. This study aims to investigate the level of awareness, adoption, and effect of factors driving the circular economy adoption on the financial performance of micro, small, and medium enterprises (MSMEs) in Saudi Arabia. The survey was conducted among 301 MSMEs, and the method of logistic regression was utilized for its analysis. The results revealed that the level of awareness is averagely high, with an average of seven out of 10 enterprises. However, the outcome further showed that only an average of three out of 10 had implemented a circular economy during the period of the survey. In addition, logistic regression revealed the significant influence of drivers of circular economy adoption on the financial performance of MSMEs. The following drivers of circular economy adoption have a great likelihood and significant effect on the enterprise’s financial performance: training of employees, availability of financial resources, top management commitment, digital technology, product/service upgrade, material generated/buy back cheaper to use, and pressure from people. This is based on the outcome of logistic regression of the survey conducted on the factors driving circular economy adoption in the previous literature. However, the results revealed that regulatory incentives toward the environment and pressure from government and companies are not significant. Hence, this study provides policy implications for stakeholders in the circular economic system.

Authors: Elfan Kaukab M.
Published: July 2024

Companies try to survive and gain competitive advantage by leveraging their innovation capabilities, which need to be more accurately measured through company annual reports to provide valuable insights for investors and stakeholders. The study aims to analyze how innovation capability can be understood using innovative textual analysis based on linguistic cues to assess the level of a company’s innovation capability using secondary data from companies’ annual reports and then validated by empirical tests. The study surveyed 30 companies listed on the Indonesian Stock Exchange from various sectors and industries and applied panel data regression with a five-year time series (2018–2022). Innovation capability was an independent variable, measured by textual analysis approach, and return on assets (ROA) and return on equity (ROE) were dependent variables. Descriptive statistics showed no significant differences in innovation capability, ROA, and ROE across sectors. Correlation analysis revealed no significant association between company age and these variables. Panel data regression confirmed that innovation capability positively influences ROA (p-value 0.078) and ROE (p-value 0.035). Notably, the impact of innovation capability on ROA increased during and after the COVID-19 pandemic, highlighting its growing importance in financial performance during challenging times.

Published: July 2024

Twitter is a popular social media with hundreds of millions of users, but some are not human. About 48 million accounts are created by Build Operate Transfer (BOT), which represents up to 15% of all accounts. BOTs are created for various purposes, one of which is to post information about news automatically. However, BOTs have also been abused, such as spreading hoaxes or influencing public perception of a topic. The research aimed to determine which Twitter accounts were identified as BOT accounts based on predefined attributes. The research used tweet data from 213 Twitter accounts. The accounts used as test data were accounts that had influence. After that, the data were clustered using k-means using the attributes of retweets + replies count, followers count, account age, friends count, status count, digits count in name, username length, name similarity, name ratio, and likes count. The results show the optimal number of clustering at k = 3 on the Sum of Squared Errors (SSE) evaluation and the Elbow method and the best quality and cluster power at k = 2 on the silhouette coefficient. It shows that the clustered accounts with the highest number of members on each attribute are places for accounts with high BOT scores from several aspects of the BOT score type.

Published: July 2024

The first model of oxygen transport was formulated by August Krogh. However, the investigations conducted have yet to yield a complete analytical model and a widely applicable solution for One-Dimensional (1D) network construction. The research sought to provide numerical and analytical solutions for the oxygen transfer model in mitochondrial cells to enable researchers to estimate the molecular dynamics and diffusion characteristics in mitochondrial cells. The oxygen diffusion process in mitochondria was modeled with ID numerical models. The numerical models used to solve the equations were explicit and implicit. The explicit model consisted of Forward Time Center Space (FTCS) and DuFort-Frankel. Meanwhile, the implicit model had Crank-Nicholson and Laasonen. The numerical solutions of the explicit and implicit were divided into four scenarios with a variation of Δt and compared with the analytical solutions. The results show that the Laasonen method is the best in describing the diffusion process. The best scenario with the lowest slope value and small Root Mean Square Error (RMSE) value is scenario 2 (Δt = 3,33E-4 s and Δx = 2,00E-5 cm). The numerical model and analytical solution show that the time required to reach a steady state is 0,7 s. It indicates oxygen exchange in two sides of the mitochondrial cell after 0,7 s.

Published: July 2024

The rapid progress of Information and Communication Technology (ICT), especially the Internet, has changed lifestyles in profound ways, including sharing ideas, virtual interactions, digital entertainment, and online transactions. It has resulted in businesses globally turning to electronic commerce (e-commerce) to market products. E-commerce has revolutionized operations with features such as centralized storage and detailed product information in the marketing process. However, the inefficiency and lack of transparency in these centralized systems lead to high costs and limited user control, posing a significant challenge. Challenges include commission fees from E-Commerce providers, which hinder business growth. The research aimed to propose a more efficient and transparent model for Consumer-to-Consumer (C2C) e-commerce using blockchain technology. The C2C model enhanced user transactions and minimized third-party dependence, but centralization increased costs and limited seller access. Thus, a decentralized blockchain approach was proposed for greater transparency in e-commerce. The research innovatively applied blockchain to C2C e-commerce, enhancing market efficiency and transparency. The research method applied was a combination of Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis and practical application. The result shows that the approach succeeds in reducing high costs, transparency of data storage, and dependence on third parties. Blockchain reduces third-party involvement and promotes a fairer business environment because it uses a tamper-proof database for transparency, security, and efficiency in the ever-growing e-commerce ecosystem. Blockchain ensures automated transactions, real-time data tracking, and data security.

Published: July 2024

Microparticulated whey protein can be used as a fat substitute in foods to enhance their nutritional value and improve their sensory and rheological characteristics. Microparticulation denatures whey proteins through heat treatment, followed by shear rate control to determine the aggregate sizes formed. The processing method used during microparticulation can modify the protein denaturation rate, which may enable the application of new proteins. This study sought to develop a methodology for quantifying whey protein fractions in commercial samples before and after microparticulation at different concentrations and physical states. The developed methodology proved to be applicable because of its selectivity, quantification, detection limits, and precision. The analyzed samples exhibited a higher denaturation rate for β-lactoglobulin than α-lactoalbumin; the denaturation rate varied among samples due to differences in the microparticulation process.

Phosphorus recovery potential from sewage sludge by struvite precipitation: remodelling policy framework in Rajasthan, India
Authors: Srivastava Ankit , Saxena Kanika , Brighu Urmila
Published: July 2024

The manufacturing of fossil-based fertilizers by extraction of rock phosphate has contributed to carbon emissions and depleted the non-renewable phosphorus reserves. Sewage sludge, which is a waste product from Sewage Treatment Plants (STPs), is rich in phosphorus. The existing techniques for sludge management contribute to carbon emissions and ecological footprint. Struvite (raw fertilizer) and biochar recovery from sludge has emerged as viable methods to reduce carbon emission and ensure economic sustainability of STPs. In this work, the potential for phosphorus recovery and revenue generation is discussed for Rajasthan state in India. The fate of phosphorus and heavy metals in STPs is evaluated which indicates that about 70% of the phosphorus and trace amounts of metals end up in sewage sludge. Further, the power consumption is high in STPs due to industrial wastewater ingress. There is a need to bridge the gap between sewage treatment and generation in Rajasthan, improve STP performance before resource recovery inclusion at policy-level and scale-up. Mixing struvite with biochar can lead to safe application of struvite as raw fertilizer as heavy metals are sequestered by biochar. A business framework is developed to serve as a blueprint and potential model for linking technical and market viability.

Conservar o meio ambiente mediante implementação de unidades de conservação, ou seja, designar áreas que devem ser especialmente protegidas e como instrumento de gestão dos remanescentes florestais e do solo, é uma tendência mundial cada vez mais praticada. Para tal, é necessário recolher as representações sobre os anseios, as necessidades e os valores da população inserida nesses locais, que geralmente são bastante habitados. Nem sempre as comunidades que detêm essas áreas são incluídas nas decisões sobre as condições atuais e futuras das unidades de conservação. A implantação de unidades de conservação pode causar impactos socioculturais. Este artigo fez uma análise sobre os conhecimentos da comunidade do bairro Adhemar Garcia, vizinha ao Parque Natural Municipal Caieira, uma unidade de conservação de proteção integral na cidade de Joinville, SC. A metodologia utilizada foi apoiada em uma abordagem qualitativa, com alguns dados quantificáveis, em que, com o uso da vocação hierarquizada de palavras, a comunidade atribuiu valores por meio de suas representações sociais. Os valores identificados foram: “negativista”, “moralista”, “naturalista”, “estético”, “ecológico-científico”, “humanista”, “utilitarista” e “dominador”, demonstrando como a comunidade vê o Parque. Esses valores oferecem subsídios para que eles sejam reelaborados, por meio do envolvimento da comunidade com a unidade de conservação em questão.

The present research aimed to analyze biometric characteristics of Campomanesia xanthocarpa and its fruits and its fruit yield. This study was developed in araucaria forest at Irati National Forest, Paraná state. To perform this analysis, 31 individuals were selected and the total height and commercial height, diameter breast height (DBH), crown diameter, crown length, crown proportion, crown formal, salience index, range index and slenderness rate were measured. From the fruits, variables as length, width, weight and number of seeds per fruit were measured. The fruit yield was estimated by means of the fruit number per branch and the average fruit weight per tree. The species presented total height, DBH and crown diameter of 14.2 m, 32.09 cm and 9.5 m, respectively. The crown diameter is 30 times greater than DBH, and 49.71% from total height is occupied by its crown. The fruits presented 22.01 mm, 19.74 mm, 6.64 g and eight units for width, length, weight and seeds/fruit, respectively. The yield was 1.273 fruits, with 8.64 kg.tree-1. The species presents slow growth, with slender crown and resistance to weathering. Its fruits had great potential for selection for commercialization.

Published: July 2024

A Bacia Hidrográfica do Rio Cachoeira está inserida integralmente no município de Joinville, Santa Catarina, percorrendo um trecho predominantemente urbano. Grande parte da sua vegetação ciliar já foi removida, restando apenas alguns fragmentos. O objetivo deste estudo foi caracterizar, ao longo da bacia hidrográfica, a comunidade de aves que ocorre em fragmentos próximos e também às margens do Rio Cachoeira. Realizaram-se duas campanhas (abril e novembro de 2016), com duração total de 12 dias cada, distribuídas em cinco pontos de amostragem. Para o inventário, foram utilizados transecções e pontos fixos previamente definidos em cada ponto de amostragem. Durante o período, identificaram-se 241 espécies de 63 famílias. O ponto de maior riqueza foi a área Itinga, com 199 espécies, e aquele com menor riqueza foi o das transecções na margem do rio, com 116 espécies. A área Itinga representa o maior fragmento amostrado, com grande concentração de palmito (Euterpe edulis), o que favorece a alimentação de várias espécies e contribuiu para a sua manutenção. Um total de 12 espécies está inserido em alguma categoria de ameaça, o que reforça a importância desses fragmentos para a sobrevivência de tais espécies. A Bacia Hidrográfica do Rio Cachoeira apresentou uma avifauna muito rica e merece especial atenção considerando a forte pressão da urbanização que vem sofrendo.

The study examines the role of transformational leadership and Dynamic Managerial Capabilities in public sector innovation, specifically in addressing the challenges of managing the livelihood eligibility of the community, including older people, in order to build an elderly-friendly community. The study focuses on the leadership of Jambi Mayor and Vice Major in employing innovation to realize Jambi as a Smart Living. This descriptive qualitative study aims to identify new information related to the transformational leadership and Dynamic Managerial Capabilities of the Jambi Government in innovating feasible urban living. The authors identified transformational leadership as a major style in carrying out innovation and dynamic managerial capabilities. The study found that Jambi City is continuously promoting the importance of creating smart living as one of the smart city indicators, especially in elderly-friendly cities, through the leadership of its mayor and vice mayor. Both initiated change by identifying challenges and opportunities, finding good examples of smart living, inspiring and implementing innovations, encouraging changes in how the bureaucracy works, and motivating civil servants to improve their attitudes and assumptions, especially toward health services for the elderly. The study concludes that leadership style and dynamic managerial ability to adapt to change contribute to the success of smart living innovation.
Spinoza and Spinozism in Twenty-First Century Anglophone Philosophy
Authors: Steinberg Justin
Published: July 2024

In this paper, I survey some prominent developments in Spinoza scholarship in English-speaking countries in the past quarter-century. Picking up where Tom Cook left off in his analysis of the reception of Spinoza in Anglo-American philosophy in the hundred years after the founding of the Vereniging Het Spinozahuis (1897–1997) (“Spinoza's Place in Twentieth Century's Anglo-American Philosophy”), I seek to identify some of the main currents in the rich profusion of twenty-first century Spinoza scholarship in the USA, UK, Canada, and Australia. Scholarship on Spinoza’s metaphysics has continued to blossom, harkening back in some respects to the idealist interpretations with which Cook opens his survey. But whereas there was a notable lack of scholarly works on Spinoza’s moral and political philosophy in the twentieth century, there is now an abundance of scholarship in these fields. I will conclude by examining the reach of Spinozism in the twenty-first century, looking at the ways in which scholars and journalists have presented Spinoza’s philosophy to a non-academic readership, and exploring the ways in which contemporary metaphysicians and philosophers of emotion and cognition have cast their work under the “brand” of Spinozism.
The History of Reception as a Battlefield: French uses of “Spinoza” in the nineteenth and twentieth centuries
Authors: Lantoine Jacques-Louis
Published: July 2024

The French reception of Spinoza during the nineteenth and twentieth century shows that what we call the “reception” of a corpus must be understood in a quite different way than the word suggests. The receiver must be disposed to make use of the corpus, and this attitude is determined by the receiver’s position within the structure of the academic or intellectual field. Spinoza was received in France in the early nineteenth century because it played a strategical role in the debate about pantheism as an atheism. But the “Spinoza” that was inherited was a corpus of works, while a certain reading of it had been elaborated in another context for other goals, namely, that of German idealism. Reception is not merely passive: the receivers impose their own structure to what affects them. At first, “Spinoza” was a figure or a label that played a role in a battlefield. This is still true for what we may call (albeit not in an ontological sense) the “materialist” reception in the 1960s. Yet, it was not doomed to give a purely imaginative knowledge of “Spinoza”: a better knowledge of the corpus, international exchanges between scholars of all over the world, and history of reception itself, made a rational knowledge of Spinozism, and even a singular understanding of Spinoza, possible.
Spinoza and Twentieth-century Italian Culture
Authors: Mignini Filippo
Published: July 2024

The paper distinguishes between philosophy and culture and explains the reasons why it is preferable to investigate the relationships between Spinoza and the Italian culture (rather than philosophy) of the twentieth century. Italian culture is characterized by five prevailing forces: Roman Catholicism, the neo-idealism of Croce and Gentile, fascism, Marxism, the mass media. Spinoza’s conceptual world has remained foreign to Italian culture, where it has not been expressly opposed, as, for example, by the Catholic side. The paper then examines some of the main philosophical interpretations of Spinoza (as advanced by Giovanni Gentile, Piero Martinetti, Augusto Guzzo, and Antonio Banfi) showing the relationships between them, the philosophy of their authors, and some salient characteristics of the Italian culture of the century. The theologizing attitude of these philosophers (except Banfi), although expressed in different forms, led them to often misleading interpretations that contributed to nullifying a possible encounter between Spinoza and Italian culture. Finally, mention is made of the historical, philological and exegetical research which, over the last thirty years, has offered a new and significant contribution, with an international impact, to Spinoza studies.
Using School-Based Teleconsultation Services to Make Community Health Services Accessible in Semirural Settings of Pakistan: Sequential Explanatory Mixed Methods Study

Background

In Pakistan’s remote areas, quality health care and experienced professionals are scarce. Telehealth can bridge this gap by offering innovative services like teleconsultations. Schools can serve as effective platforms for introducing these services, significantly improving health service access in semirural communities.

Objective

This study aims to explore the feasibility of introducing school-based teleconsultation services (TCS) to strengthen community health in a semirural area of Karachi, Pakistan.

Methods

This study used a mixed methods design. A total of 393 students were enrolled for the quantitative component, while 35 parents, teachers, and community stakeholders participated in the qualitative arm (focused group discussion). Proportional computation for the quantitative data was done using SPSS (version 24; IBM Corp), while qualitative data underwent thematic analysis.

Results

A total of 1046 successful teleconsultations were provided for 393 students over 28 months. The demographic data showed that the mean age of the students availing TCS was 9.24 (SD 3.25) years, with the majority being males (59.3%, 233/393). Only 1.24% (13/1046) of cases required referrals. The qualitative analysis yielded three themes: (1) transformation of the health care experience, (2) escalating demands for teleconsultation, and (3) the psychological aspect of care.

Conclusions

This study demonstrated the efficacy of integrating TCS in a semiurban school in Karachi to address health care accessibility gaps. Implementing TCS through the school platform improved the overall health status of school children while reducing school absences and financial burdens on families. The study highlighted TCS’s cost-effectiveness, time efficiency, and quality, with community support for 24/7 availability, expansion to adults, and a reimbursement model. School health nurse-led TCS offers a scalable solution to health care challenges, enhancing health outcomes for school-going children in Pakistan and globally, particularly in low- and middle-income countries, where accessibility is a major issue.
