Published: January 2025

The continuing reduction of supply voltage for reliable operation of analog integrated circuits is widely recognized. Analog circuits must adhere to this trend. As a result, researchers are currently developing low-voltage analog circuit methodologies. Current-mode signal processing circuits are examples of these concepts. Therefore, the objective of this work is to present circuit realizations of low-voltage current-mode logarithmic and exponential function generators with temperature compensation. Both the input and output signals operate in current mode. The design approach utilizes the current-mode translinear technique to produce the output currents that exhibit a directly proportionality to the absolute values of the logarithmic and exponential functions. By simply adjusting the external bias currents, one can electronically tune the output currents and transfer current gains for both proposed circuits. The proposed circuits utilize only npn bipolar transistors and can operate with low-level supply voltages of ±1V, which are appropriate for low-power, high-frequency applications. Nonideality performance considerations are also discussed in detail. In order to verify the operational function of the circuits and illustrate their superior thermal stability, the PSPICE simulation has been performed using real transistor models provided for the HFA3096 mixed bipolar array technology. The simulation findings illustrate that the proposed logarithmic and exponential amplifier circuits can compensate for temperature variations, as evidenced by the good stability of their output currents over a temperature range of -40 °C to 100 °C.

Published: January 2025

The large dimensions and extra weight frequently encountered on the Pantura line create a need for policymakers to introduce allowances for logistics transportation services using government-subsidized funds, particularly directed at railway logistics services transporting goods on this route. This study focuses on optimizing subsidy allocations to KALOG (the Indonesian Train Logistics Company) by examining three key factors: logistic railway service expenses, the distance between industrial centers and the nearest KALOG facilities, and truck operational costs. These elements are instrumental in enhancing KALOG's profitability while reducing issues related to overdimensioning and overloading along the Pantura line. Centered in Jakarta, which also serves as the nation’s logistics hub, the railway network extends to major cities including Tangerang, Bandung, Semarang, Yogyakarta, and Surabaya, offering substantial potential to improve the efficiency and reliability of rail freight in Indonesia. The study uses an optimization simulation to determine the optimal percentage for subsidy allocation, aiming to maximize profitability and, in turn, benefit both KALOG’s capital accumulation and Indonesia’s broader economic infrastructure. Numerical estimates generated in the simulation indicate that reallocating subsidies toward rail transport rather than highway logistics can lower operational costs significantly and reduce traffic congestion and road damage on highways in the Pantura region. Additionally, by adjusting for increased demand in logistics railway services through measures such as adding more wagons or improving infrastructure, the subsidy allocation model enhances rail transport's economic viability. The results provide a clear picture of the impact that a targeted optimization strategy can have on both the performance and competitiveness of logistics companies – particularly in the rail sector. Through continuous innovation, adapting to market changes, and prioritizing high-quality services, logistics companies not only enhance their competitive edge but also contribute to long-term, sustainable growth, benefiting Indonesia's logistics sector and national development
Biological activities and phenolic content of endemic Helichrysum artvinense P.H. Davis et Kupicha (Asteraceae)
Authors: Acet Tuba , Özcan Kadriye , Aksu Kalmuk Nursen
Published: January 2025

Species from the Asteraceae family have been extensively utilized in traditional medicine and as food sources for centuries. They also exhibit important biological activities attributed to their diverse array of phytochemical compounds. This research aimed to determine total phenolic and flavonoid contents of ethanol (EtOH) and methanol (MeOH) extracts of endemic Helichrysum artvinense and to reveal its antioxidant, antimicrobial enzyme inhibitory (α-glucosidase, α-amylase, and tyrosinase) and DNA protective activities. In addition, phenolic compound analyses were conducted using high-performance liquid chromatography (HPLC), establishing a correlation with the aforementioned biological activities. Based on the obtained data, the ethanol (EtOH) extract of the plant demonstrated greater prominence in terms of the screened biological activities. This extract was found to contain significant phenolic components, including epicatechin, chlorogenic acid, and luteolin. Consequently, it appears that the plant has the potential to serve as a natural alternative in both food and pharmacological applications. However, further studies to elucidate the mechanisms underlying the observed biological activities would be beneficial for the product development phase.
Effect of ZnO nano priming on germination and root length of soybean seeds (Glycine max L.)
Authors: Akbay Burcu , Yalçın Fehime Sevil
Published: January 2025

Nano-priming is a pioneering method of treating seeds that improves seed germination, growth, and yield by imparting resilience to several plant stressors. Zinc oxide (ZnO) is a nanomaterial with a specific surface area, high pore volume, low toxicity, and an extended lifetime, and used in nano-priming. This study aimed to determine the effect of ZnO nanoparticles (NPs) on seed germination and root length in determining the optimum concentration of ZnO-NPs for soya plants. The transmission of electron microscopy (TEM) and zeta potential measurements were used to characterize ZnO-NPs. Soya seeds were treated with different concentrations of ZnO-NPs (0, 250, 500, 1000 and 2000 mgL-1) for 24 h. to determine the optimum concentration of ZnO-NPs for selected variants. After priming, the germination percentage and root length of each treatment were measured. The effect of ZnO nanoparticles (in soya plants was investigated by comparing them with seeds germinated in a control (hydro-priming) medium. The investigation demonstrated that the high concentration of ZnO NPs had an adverse impact on both seed germination and root length. Based on this, it was suggested that studies should be conducted including different concentrations of ZnO nanoparticles, which are thought to have a complex structure, to understand the mechanism of action, to find the appropriate concentration for soybean plants, and to increase seed germination.

Published: January 2025

In this study, the detection status of security attacks on smart vehicles is analyzed. In our study, synthetically produced data will be detected using the EWMA algorithm. In this algorithm, a data set was created and applied to this algorithm as 80% non-attack situation and 20% attack situa-tion. While applying the algorithm, the 𝛼 value in the EWMA formula was tried as 0.8, 0.7 and 0.6, and the value of 0.7, which gave the best results, was selected. In line with these choices, studies have been carried out using this algorithm and data set. In the studies carried out, the results obtained by normalization of the function determined as the selection function in the EWMA algorithm were applied according to the criteria and rates determined by taking expert opinions. Those rates and selected criteria; For EWMA, the effects were taken into account as 24 percent for rpm, 40 percent for speed, and 18 percent each for fuel quantity and accelerator pedal pressing amount. The data obtained as a result of all these studies were evaluated. As a result, warnings can be given to vehicles that will be under attack with the warnings obtained from the EWMA algorithm, or the vehicle can be saved from the attack by stopping the systems.

Published: January 2025

There is an urgent need to expand wastewater treatment on the African continent. To help choose appropriate technologies for this task, we evaluated the efficiency, energy and chemical demands, and costs of four wastewater treatment plants (WWTPs). These plants represent the main wastewater treatment technologies operated by the Addis Ababa Water and Sewerage Authority (AAWSA): waste stabilization pond (WSP), anaerobic baffled reactor (ABR), up-flow anaerobic sludge blanket with trickling filter (UASB-TF), and membrane bioreactor (MBR) technologies. Principal component analysis revealed that season significantly impacts the raw and treated wastewater quality (ANOSIM, R = 0.3126, p = 0.001), while the type of treatment plant did not significantly affect the measured effluent characteristics (ANOSIM, R = 0.1235, p = 0.2000). In contrast, construction and operational costs, as well as energy and chemical demands per m3 of treated wastewater, varied starkly between the WWTPs. Total costs of wastewater treatment in 2022 ranged from $0.045 to 0.546 per m3 of wastewater treated, being 6–12 times higher for MBR compared with the other WWTP technologies. Real-world performance data as reported in this study are essential for choosing appropriate technologies that meet Africa's wastewater treatment needs.

Authors: Shi Hanfei , Sun Kai , Wang Yan
Published: January 2025

Background

Cheilitis glandularis (CG) is a rare inflammatory disorder affecting the minor salivary glands. Nonetheless, the ideal management of CG remains elusive. Hence, this study aimed to broaden the understanding of the etiopathogenesis of CG and recommend bacterial culture and drug sensitivity tests for CG patients with suspected infection.

Case Presentation

A 78-year-old female came to our hospital complaining of painful protrusion in her right lower labial mucosa for three weeks. Clinical examination revealed local enlargement with pyorrhea on the right lower labial mucosa. Histopathological examination indicated the features of CG. Bacterial culture and drug sensitivity test demonstrated Pseudomonas aeruginosa (P. aeruginosa) infection with several susceptible antibiotics. The patient was treated with surgical excision of the right lower labial mucosa combined with levofloxacin daily for two weeks. At the 4-week follow-up after excision, only a small amount of scar remained in the excision area. The patient had no symptoms in the oral mucosa.

Conclusion

CG may be accompanied by P. aeruginosa infection. Bacterial culture and drug sensitivity tests may contribute to identifying potential pathogens in CG patients and improving the efficacy of the treatment.

University as "preparation for life": An investigation on parents' metaporical expressions
Authors: Güngör Cumhur
Published: January 2025

In the contemporary era, the transition from adolescence to adulthood primarily begins with the choice of university, where parental guidance and influence are significantly pronounced. This research aims to unveil the perceptions parents hold towards the concept of "university" through the use of metaphors. It is a qualitative study designed to describe and interpret the metaphorical thoughts of parents whose children are university students, regarding the phenomenon of university. Content analysis, a commonly employed method in qualitative research analysis, was utilized. The study's participants consist of parents of students enrolled in various undergraduate programs across universities in our country during the fall semester of the 2022-2023 academic year. The sample includes 163 parents. In the study, 142 metaphors produced by parents are analyzed under different categories by subjecting them to content analysis. The metaphors of parents regarding the concept of university are grouped under 12 categories. The analysis of metaphors produced by parents regarding the concept of "University" indicates a predominantly positive perception, characterized by a blend of abstract and concrete expressions. The metaphors most frequently cited—"Life," "Family," "Home," "Development," and "Education"—highlight the university's integral role in personal development, social relationships, and intellectual enrichment. This suggests that parents regard the university not only as an educational institution but as a pivotal life stage pivotal for overall development and social integration. The analysis of parental metaphors concerning the university concept reveals a comprehensive perspective that transcends the educational scope, highlighting its significance in personal growth, intellectual development, social integration, and professional preparation.

Bu doğrultuda görüş sunan katılımcılar bunun nedenini; öğretmen ve toplumun gözünde saygın bir yer edinmeye, ulaşılmak istenilen hedeflerinin olmasına, başarılı olma/aynı başarıyı yakalama, maddi destek ve ödüllere sahip olma isteğine dayandırmıştır. Dezavantajlı yüksek başarılı öğrencilerin benzer dezavantajlara sahip öğrenciler üzerinde devamsızlık ve davranış sorunlarında azalma, kitap okuma eğiliminde artma, okula karşı olumlu tutum geliştirme, özgüven ve motivasyon yüksekliği ve bireysel yeteneklerin ortaya çıkması gibi olumlu yansımalarının olduğunu saptanmıştır.
A Model of State-Owned Asset Management Based on Pancasila Values: Achieving the Highest and Best Use
Authors: Koeswahyono Imam
Published: January 2025

This article discusses the formulation of a model called "Sustainable and Equitable Organization and Management of State/Region/Village-Owned Assets Based on the Pancasila". The authors introduce a “highest and best use” approach to state asset management, aiming to address gaps in existing norms around asset governance, particularly regarding the absence of a mechanism for asset management and dispute resolution. This condition can potentially bring about corruption through the exchange of state land assets that are unequal in value. The model initiated by the authors comes from the need to elaborate the legal politics of Pancasila into laws that specifically regulate the management of state assets with the principle of best utilisation oriented towards the greatest prosperity of the people. This conceptual research aims to formulate and develop a research model with the following outputs: a. to find a paradigm for agrarian legal research that is based on the critical agrarian approach in the perspective of legal science; b. to determine the integrity and harmony with the Pancasila philosophy, and the constitutionality of regulation and institutionalism, of the management of state/region/village-owned assets; c. to formulate an institutional model for conflict resolution in agrarian affairs, primarily for cases of conflict involving state/region-owned assets in the form of an agrarian court that can resolve and eliminate the backlog of cases of agrarian conflicts for both public and private aspects specifically, with legal certainty and justice. Achieving this goal requires establishing a State Asset Management Agency and the existence of an Agrarian Court. The weakness of this idea lies in the realization of forming regulations that need to be in harmony with related laws and regulations. This model is necessary for synergising the roles of legislators, stakeholders, and the public based on the principle of sustainable and just management of state assets according to Pancasila.

Published: January 2025

BACKGROUND

Wearables are increasingly used in pediatric cardiology for heart rate (HR) monitoring due to advantages over traditional heart rate monitoring, such as prolonged monitoring time, increased patient comfort and ease of use. However, their validation in this population is limited.

OBJECTIVE

This study investigates the HR accuracy and validity of two wearables, the CardioWatch bracelet and Hexoskin shirt, in children attending the pediatric cardiology outpatient clinic. In addition, factors that influence HR accuracy, the Hexoskin shirt's arrhythmia detection efficacy, and patient satisfaction are investigated.

METHODS

Children indicated for a 24h-Holter ECG were equipped with a 24h-Holter ECG (gold standard), together with both wearables. HR accuracy was defined as percentage of HRs within 10% of Holter values and agreement was assessed using Bland-Altman analysis. Subgroup analyses were conducted based on body mass index (BMI), age and time of wearing, among other factors. A blinded pediatric cardiologist analysed Hexoskin shirt data for rhythm classification. Patient satisfaction was measured using a 5-point Likert-scale questionnaire. 

RESULTS

Thirty-one participants (mean age 13.2±3.6 years; 45% female) and thirty-six (mean age 13,3±3,9) participants were included for the CardioWatch and Hexoskin measurements respectively. Mean accuracy was 84.8% (±8.7%) for the CardioWatch and 87.4% (±11.0%) for the Hexoskin shirt. Hexoskin shirt accuracy was notably higher in the first 12 hours (94.9±7.4%) compared to the latter 12 (80.0±16.7%, P<.001). Higher accuracy was observed at lower HRs (low vs. high HR: CardioWatch: 90.9±9.3% vs. 79.0±10.6%, P<.001; Hexoskin shirt: 90.6±14.0% vs. 84.5±11.8%, P<.001). Both wearables demonstrated good agreement in their HR measurement with Holter readings (CardioWatch bias: –1.4 beats per minute [BPM]; 95% Limits of Agreement [LoA]: –18.8 to 16.0. Hexoskin shirt bias: –1.1 BPM; 95% LoA: -19.6 to 17.4). Correct classification of the Hexoskin’s shirt rhythm recordings was achieved in 86% (31/36) of cases. Patient satisfaction scores (median[range]) were significantly higher for both the CardioWatch (3.8[3.5–4.3], P<.001) and Hexoskin shirt (3.7 [3.0–4.0], p<0.001) compared to the Holter ECG (2.6 [2.1-3.2]).

CONCLUSIONS

The Corsano CardioWatch and Hexoskin shirt demonstrate good accuracy in pediatric HR monitoring and provide higher patient comfort than conventional monitoring. Both wearables show good agreement in relation to the gold standard device. However more research is needed to explore the reasons for inaccuracy during higher heart rates. The Hexoskin shirt also shows potential in arrhythmia detection. While further development is warranted, these wearables show promise in enhancing diagnostics, therapeutic monitoring and patient safety in pediatric cardiology.

“They Always Kept That Very Icon”: Memories of Old Believers about the Practices of Interaction with Icons in Soviet and Post-Soviet times
Authors: Dushakova N. S.
Published: January 2025

The article deals with the practices of venerating icons among Old Believers in the context of anti‑religious policy in the USSR and their transformation after the end of religious persecution. The data comes from ethnographic observations and memories recorded from 2008 to 2023 among the Old Believers of the North‑Western Black Sea region as well as migrants from this region to other parts of Russia. Since the narrativization of personal experience occurs with the support of material objects, ethno‑confessional symbols play an important role in autobiographical memories of manifesting everyday religiosity. The article shows the role of icons in the perception of religious experience, transmitting ideas about one’s faith as well as rules of interaction with an icon in different contexts. During anti‑religious campaigns, the veneration of icons was transferred to a safe space hidden from the external environment, and the most significant thing for a believer, judging by the interview materials, was the very fact of the presence of the sacred objects in the home space. After the end of religious persecutions, new rules were formulated that allow for a freer arrangement of icons in the house, with less rigid regulating rules. Still there are prohibitions on placing a bed under the icon, or placing a mirror or mobile phones next to it, or placing a TV set at the sacred corner / under the icon / opposite the icon, etc. An important function of home icons is to preserve memory about the past. The choice of the most revered images is determined by events significant for family history, often associated with overcoming a difficult past, which is clearly manifested in the tradition of “serving a holiday” / “taking a holiday into the house,” thus establishing a votive holiday, which is then passed on from generation to generation.
Sacred Corner in a Peasant’s Dwelling: Sacred, Informational and Communicative Functions
Authors: Levkievskaya E. E.
Published: January 2025

The article analyzes the evolution of the «sacred corner» and its structure in the Russian peasant tradition from the point of view of vernacular functions that it performed in the peasant house of the 19th — early 21st centuries. The work was carried out at the intersection of ethno‑linguistic, ethnographic and cultural methods. The material for the work comes from field research of the last two decades in the Lower Volga region and in the northwestern regions of Russia as well as ethnographic data of the 19th–20th centuries. The evidences of foreigners who visited Russia in the 16th–18th centuries are used to understand the history of а sacred corner formation. A pragmatic analysis of the available data makes it possible to consider the sacred corner (in the form in which it has been known since the 19th century) as a complexly structured locus of a peasant dwelling. The sacred corner performed broader mental and information functions besides the sacral one. The sacred corner was a symbolic center that reflected the intellectual interests and the worlview of the house owner. The sacred corder retained and expanded the status of an information and communicative center in the 20th century in spite of atheistic persecution it now included both a radio or TV sets as well as the most important information, from psalms and the Bible to medical prescriptions and notes with ritual spells.
The New Year Tree and the Foil Icon: Non-Obvious Kinship and Social Biographies
Authors: Antonov D. I.
Published: January 2025

The article examines two objects that spread in the Russian Empire in the first half of the XIX century and, it would seem, had little in common: Christmas trees and kiotki icons (religious images in wooden kiotki decorated with foil). As the author shows, from the very first decades of their existence, these hybrid artifacts turned out to be related to each other in many ways. They were united by the materials used — foil, paper, chromolithographic images, etc.; The principles of decoration are, first of all, imitation of precious metals, the use of inexpensive sparkling decorative elements; crafts and production practices that supplied them with these elements. The morphology and symbolism of the Christmas tree were closely tied to the Christian context and obviously converged in this with the icon. Finally, the practices of interacting with these objects and the emotional registers associated with them also had a lot in common. The religious and near‑religious home object developed along similar trajectories throughout the 19th century. After the revolution, in the wake of anti‑religious campaigns, the Bolsheviks tried to destroy these artifacts and the rituals in which they were involved. However, both the icon and the Christmas tree survived the persecution of the 1902s and 1930s, and adapted to new cultural and material conditions. The morphology of the Soviet Christmas tree and the Soviet icon turned out to be related again. Later, the icons began to borrow elements first from pre‑revolutionary, and then from Soviet Christmas trees, which brought these bricolage objects even closer. Finally, in recent decades, the Soviet Christmas tree toy and the Soviet icon have been experiencing similar scenarios, turning into a cultural, scientific and museum object.
Soviet Icons and the Material Religion of the Communist Era
Authors: Antonov D. I.
Published: January 2025

Soviet icons are a phenomenon that has been discovered and conceptualized in recent years. These are the most massive religious artifacts that were created during the Soviet era. They are complex objects: prayer images placed in a wooden case, decorated with chasubles and complex decor. Soviet icons are the heirs of the foil icons, which spread massively in the Russian Empire in the second half of the 19th — early 20th century. Artifacts of this type are an “information container” — the principles of their manufacture, functioning, and perception conceal the most important information about cultural strategies, religious practices, social interactions, and the material realities of the epoch. The creation of Soviet icons required the construction of many shadowy social networks. The tools and materials that Soviet craftsmen used mirrored the realities of the Soviet village. Until recently, these objects did not attract the attention of specialists. In modern Russia, they are rapidly disappearing — perceived as “outdated” objects and “church garbage” they are being disposed of. A comprehensive study of these icons and the social contexts in which they existed and continue to exist is an urgent scientific task. It helps to reveal not only the religious and social specifics of the Soviet province, but also many processes taking place in post-Soviet urban and rural society. This work explores important trends in the religious life of church and monastery communities, and in much broader social circles — among pilgrims, parishioners and people who occasionally visit churches. The article describes the history of the discovery of Soviet icons. The author also focused on the material, social and cultural uniqueness of these artifacts, and examines post-Soviet scenarios in which they are involved.

This study aimed to test and analyze the effect of workplace spirituality and work discipline on employee performance, with work motivation as a mediating variable. This study uses quantitative methods involving a population of all Tulungagung Regency Environmental Service employees. The survey was conducted using the Non-Probability Sampling method for 98 employees. The data were processed using SmartPLS version 4.0 with validity, reliability, and hypothesis testing. The results showed that workplace spirituality did not significantly affect employee performance, and work discipline did not considerably affect employee performance. Furthermore, work motivation affects employee performance. Work Motivation can also mediate the relationship between Employee Performance and Workplace Spirituality. In addition, Work motivation can also mediate the effect of Work Discipline on Employee Performance on employees of the Tulungagung Environmental Service. This research implies that focusing on Spirituality in the workplace can improve employees' emotional and psychological well-being, which can increase job satisfaction and loyalty to the organization.

In this issue we are delighted to showcase several research articles that trace their origins to the Irish Learning Technology Association (ILTA)’s EdTech Conference 2024, held this year in ATU Sligo at the end of May. This progression from conference presentation to peer-reviewed publication exemplifies ILTA’s commitment to advancing scholarship through the Irish Technology Enhanced Learning (IJTEL). Through the pages of this journal, we can see how initial concepts and dialogues sparked at the conference event have matured into comprehensive research contributions. This natural evolution from conference discourse to scholarly publication demonstrates the vibrant academic ecosystem that exists between practitioners and researchers supporting each other in their scholarship of teaching and learning, making their work more publicly available for peer review and critique, and for these findings to ultimately become reproducible and extensible by others.
The Power of Sharing Failures: The Effects of Failure Disclosure on Exploration Performance
Authors: Chen Clara Xiaoling , Huang Xian , Wang Laura W.
Published: January 2025

Creativity-dependent companies often implement failure disclosure programs to encourage employees to publicly disclose failures encountered in exploration activities with a focus on learning. We examine the effects of failure disclosure on employees’ exploration performance using an experiment in which participants perform a letter-search task by counting the search letters in each question (i.e., exploitation) or identifying an embedded shortcut that applies to all questions (i.e., exploration). We manipulate two factors: (1) whether participants are encouraged to disclose their failed attempts at finding the shortcut to future participants and (2) whether they are evaluated for their task-related skills. We predict and find failure disclosure increases the likelihood of shortcut identification in the presence of evaluation, and this effect is mitigated in the absence of evaluation. Because evaluation is typically present in natural work settings, our theory and results suggest failure disclosure is an effective mechanism to increase employees’ exploration performance.
Evaluación de tres dilutores comerciales sobre el semen de ovino post-congelación
Authors: Paucar Quito Janneth Elizabeth
Published: January 2025

La cría de ovinos tiene un impacto significativo en la economía del país, sin embargo, en esta industria suelen mantener prácticas de manejo tradicionales, lo que resta competitividad internacional, por esto es primordial mejorar la producción ovina mediante la mejora genética de animales con alto potencial productivo y reproductivo. El objetivo de la presente investigación fue evaluar la eficiencia de tres dilutores comerciales, Ovixcell, Andromed y Triladyl sobre la calidad espermática del semen ovino postcongelación. De acuerdo a los parámetros de cada casa comercial en semen de carneros de las razas Katahdin, Pelibuey y Dorper, con 15 extracciones, 5 por cada ovino, para un total de 45 muestras, evaluadas mediante microscopia tradicional por tinción, fluorescencia, pH, además se incluyeron parámetros cinéticos evaluados mediante el sistema CASA, todas las variables fueron evaluadas en dos intervalos, en semen fresco recién diluido y postcongelación. En los análisis de permeabilidad y progresividad en semen fresco diluido, Triladyl obtuvo resultados eficientes (p< 0.05), mientras que en cinética Andromed y Triladyl lograron un impacto notable (p< 0.05), al analizar los parámetros mencionados en postcongelación Triladyl obtuvo resultados significativos (p< 0.05) mientras que los otros testigos rotaron, Ovixcell en segundo lugar demostrando mejor resistencia a la criopreservación (p< 0.05) ante Andromed, el cual ha evidenciado un descenso significativamente drástico, indicando alta mortalidad en semen descongelado. Se concluye que el diluyente Triladyl preserva mejor las características funcionales del esperma ovino al proteger la membrana plasmática, conservando la vitalidad y brindando mayor protección ante las consecuencias de la criopreservación.

Este estudio se enfoca en evaluar el grado de adopción de las Tecnologías de la Información y Comunicación (TIC) en las micro, pequeñas y medianas empresas (Mipymes) de cuatro alcaldías de la Ciudad de México. A través de un enfoque mixto, que combina métodos cualitativos y cuantitativos, se identificó que la mayoría de las empresas analizadas se encuentran en etapas iniciales de digitalización, utilizando herramientas básicas como el correo electrónico y páginas web sencillas.
Sin embargo, se detectaron importantes barreras que limitan una mayor adopción de tecnologías digitales, entre las que destacan la falta de infraestructura adecuada, la escasez de capacitación en el uso de herramientas digitales y una cultura empresarial poco orientada hacia la innovación tecnológica.
Los hallazgos de esta investigación subrayan la necesidad de implementar políticas públicas y programas específicos para apoyar a las Mipymes en su proceso de transformación digital. Las recomendaciones incluyen desarrollar competencias digitales, facilitar el acceso a tecnologías y crear incentivos para la inversión en soluciones digitales.
Finalmente, este estudio facilita la comprensión de la situación actual de las Mipymes en términos de digitalización y proporciona información valiosa para diseñar estrategias que permitan reducir la brecha digital y fortalecer la competitividad de este sector empresarial en la Ciudad de México.
Incommensurability, Environment and Planning: A Response to Hahnel's Reply
Authors: O'Neill John
Published: January 2025

This paper responds to Hahnel’s reply to my paper ‘Pluralism, ecology and planning’ in this special issue. It focuses on disagreements concerning value commensurability and growth. It defends the possibility of rational choices in the use of resources in the absence of value commensurability. It defends the claim that the systematic drive for growth in capitalism is a central source of environmental problems and of environmental injustice. It questions Hahnel’s assertion that substitution in production and consumption alone is the only strategy to achieve environmental sustainability. Substitution is necessary but not sufficient. Environmental limits require consumption and production corridors above sufficiency for all but below excess. Those corridors are a condition for meeting the needs of the poor within environmental limits. Both the examination of environmental problems in capitalism and democratic planning require forms of in-kind analysis defended by Neurath and Kapp to address the problem of meeting human needs within environmental limits.
