Published: November 2024

ABSTRACT

Background:

The use of silver nanoparticles (AgNPs) in biomedicine has emerged in a big way owing to its antibacterial and anti-inflammatory properties. We hypothesize that combining the AgNPs with antibiotics for coating sutures will enhance the antibacterial property of sutures with the added advantage of the immunomodulatory effect of AgNPs on tissue healing.

Materials and Methods:

Polyglactin sutures were coated with AgNPs using the dip-coating method. The uniform coating and morphology of AgNPs on the suture surface were confirmed using scanning electron microscopy (SEM). Each type of suture – polyglactin plain, antibiotic coated (Triclosan), AgNP coated, and dually coated (antibiotic and AgNP) – was assessed for their antibacterial properties against Gram-positive bacteria, Gram-negative bacteria, and anaerobes. These sutures were utilized in an abdominal and systemic inflammatory mice model for ileal anastomosis. The intestinal tissue was evaluated for acute and chronic inflammation and collagen deposition to assess the healing and inflammatory response.

Results:

The SEM and energy dispersive X-ray analysis showed successful coating of AgNPs on plain and antibiotic-coated sutures. In comparison with the other groups, the dually coated suture had the best in vitro antibacterial efficacy. The AgNP-coated sutures were able to decrease both acute and chronic inflammatory cell infiltration, but the collagen synthesis and deposition were enhanced.

Conclusion:

AgNPs can be coated on Polyglactin suture either alone or in combination with antibiotics with preserved antibacterial effects. The dual coating of sutures gives a synergistic antibacterial effect. The AgNP diminishes immune response in the presence of preserved extracellular matrix generation.

Protein arginine methyltransferase-6 participates in a range of biological functions, particularly RNA processing, transcription, chromatin remodeling, and endosomal trafficking. However, it remains unclear whether protein arginine methyltransferase-6 modifies neuropathic pain and, if so, what the mechanisms of this effect. In this study, protein arginine methyltransferase-6 expression levels and its effect on neuropathic pain were investigated in the spared nerve injury model, chronic constriction injury model and bone cancer pain model, using immunohistochemistry, western blotting, immunoprecipitation, and label-free proteomic analysis. The results showed that protein arginine methyltransferase-6 mostly co-localized with β-tubulin III in the dorsal root ganglion, and that its expression decreased following spared nerve injury, chronic constriction injury and bone cancer pain. In addition, PRMT6 knockout (Prmt6
–/–) mice exhibited pain hypersensitivity. Furthermore, the development of spared nerve injury–induced hypersensitivity to mechanical pain was attenuated by blocking the decrease in protein arginine methyltransferase-6 expression. Moreover, when protein arginine methyltransferase-6 expression was downregulated in the dorsal root ganglion in mice without spared nerve injury, increased levels of phosphorylated extracellular signal-regulated kinases were observed in the ipsilateral dorsal horn, and the response to mechanical stimuli was enhanced. Mechanistically, protein arginine methyltransferase-6 appeared to contribute to spared nerve injury–induced neuropathic pain by regulating the expression of heterogeneous nuclear ribonucleoprotein-F. Additionally, protein arginine methyltransferase-6-mediated modulation of heterogeneous nuclear ribonucleoprotein-F expression required amino acids 319 to 388, but not classical H3R2 methylation. These findings indicated that protein arginine methyltransferase-6 is a potential therapeutic target for the treatment of peripheral neuropathic pain.

Published: November 2024

Olfactory receptors are crucial for detecting odors and play a vital role in our sense of smell, influencing behaviors from food choices to emotional memories. These receptors also contribute to our perception of flavor and have potential applications in medical diagnostics and environmental monitoring. The ability of the olfactory system to regenerate its sensory neurons provides a unique model to study neural regeneration, a phenomenon largely absent in the central nervous system. Insights gained from how olfactory neurons continuously replace themselves and reestablish functional connections can provide strategies to promote similar regenerative processes in the central nervous system, where damage often results in permanent deficits. Understanding the molecular and cellular mechanisms underpinning olfactory neuron regeneration could pave the way for developing therapeutic approaches to treat spinal cord injuries and neurodegenerative diseases like Alzheimer’s disease. Olfactory receptors are found in almost any cell of every organ/tissue of the mammalian body. This ectopic expression provides insights into the chemical structures that can activate olfactory receptors. In addition to odors, olfactory receptors in ectopic expression may respond to endogenous compounds and molecules produced by mucosal colonizing microbiota. The analysis of the function of olfactory receptors in ectopic expression provides valuable information on the signaling pathway engaged upon receptor activation and the receptor’s role in proliferation and cell differentiation mechanisms. This review explores the ectopic expression of olfactory receptors and the role they may play in neural regeneration within the central nervous system, with particular attention to compounds that can activate these receptors to initiate regenerative processes. Evidence suggests that olfactory receptors could serve as potential therapeutic targets for enhancing neural repair and recovery following central nervous system injuries.

Offset Active Prechamber (OAP): A Strategy to Enable Low Load GCI Operation
Authors: Gupta Saurabh K , Hanson Reed , Dempsey Adam , Kokjohn Sage
Published: November 2024

High fuel stratification gasoline compression ignition (HFS-GCI) strategies allow for the use of ignition control methods similar to those used by diesel-fueled compression ignition (CI) engines while offering the emissions benefits of gasoline-like fuels. Despite this benefit, low load GCI operation requires ignition assistance viz. intake boosting, intake heating, cylinder deactivation, etc. for consistent autoignition. A novel ignition assistance methodology using an offset active prechamber (OAP) is proposed in this work to enable low load GCI operation. A 1.5cc OAP with a pressure-sensing spark plug and gaseous fuel injection system is designed and mounted in a medium-duty single-cylinder test engine based on the Cummins ISB engine. The prechamber is provided with two holes designed to ignite the fuel spray from the centrally mounted direct injection (DI) fuel injector. Gasoline was used as the main chamber fuel and methane was used as the prechamber fuel. A detailed parametric optimization for both prechamber and main chamber parameters are performed and presented. Results show that the OAP improves the combustion stability at low load GCI operation with no thermal efficiency penalty.

Published: November 2024

The focus on sustainability has encouraged innovation across industries with a growing emphasis on minimizing environmental impact. In the transportation sector, optimizing engine lubricants emerges as a crucial avenue for achieving sustainable performance as used engine oil is the primary lubricants waste stream. Re-Refined Base Oil (RRBO) presents a compelling solution, offering a sustainable alternative to virgin base oils. By reclaiming and reprocessing used oil, RRBO not only minimizes waste but also embodies the ideology of circularity, promoting resource efficiency and environmental conservation.

This study presents the collaborative efforts between an Indian Automotive OEM and Lubricant Technology Partner towards the development of engine oil utilizing Re-Refined Base Oil (RRBO) for automotive applications. Specifically, two formulations were targeted: a 5W-30 A5/B5 oil for Bharat Stage IV passenger car usage and a 15W-40 CI4+ oil for Bharat Stage IV commercial vehicle application, both incorporating 10% RRBO.

Extensive testing was conducted to assess the physicochemical properties of the base oil and the finished oils containing RRBO. Bench tests were employed to identify performance of key parameters, including oxidation resistance, deposit formation, and corrosion susceptibility. Engine test bed and vehicle field testing were performed to evaluate the real-world performance of finished oils with RRBO. The results demonstrate that 10% RRBO-based formulations exhibit performance levels comparable to those formulated with virgin base oil, affirming the viability and efficacy of RRBO as a sustainable alternative.

In conclusion, this study highlights the integral role of RRBO in advancing circular economy principles within the automotive industry without sacrificing performance. By embracing resource efficiency and waste reduction, RRBO contributes to a more sustainable and resilient lubrication ecosystem, paving the way for a greener and more responsible future.
Experimental and Numerical Investigations on the Effect of Urea Pulse Injection Strategies to Reduce NOx Emission in Urea-SCR Catalysts
Authors: Yoshida Fuka , Takahashi Hideaki , Kotani Yuya , Zu Qiuyue , Sok Ratnak , Kusaka Jin
Published: November 2024

A major challenge for auto industries is reducing NOx and other exhaust gas emissions to meet stringent Euro 7 emission regulations. A urea Selective Catalyst Reduction (SCR) after-treatment system (ATS) commonly uses upstream urea water injection to reduce NOx from the engine exhaust gas. The NOx emission conversion rate in ATSs is high for high exhaust gas temperatures but substantially low for temperatures below 200°C. This study aims to improve the NOx conversion rate using urea pulse injection in a mass-production 2.2 L diesel engine equipped with an SCR ATS operated under low exhaust gas temperature. The engine experimental results show that, under 200°C exhaust temperature and 3.73x104 h-1 gross hourly space velocity (SV), the NOx conversion rate can be improved by 5% using 5-sec ON and 12-sec OFF (denoted as 5/12 s) urea pulse supply compared to the constant supply under time-averaged 1.0 urea equivalence ratio. It is experimentally observed that the urea pulse supply’s efficacy decreases under higher exhaust gas temperatures. The SCR model is developed with surface reactions, and the CFD results indicate that the urea pulse supply oscillates the surface reaction rates for NO and NO2, suggesting improved conversion rates. Further results on the urea pulse and constant supplies at high exhaust temperatures are reported. The NOx conversion improvement rates under various ON-OFF urea pulses are also discussed. The predicted dynamic fluctuation of the pulse supply and dithering SCR reaction is investigated.

We study deformations of certain crepant resolutions of isolated rational Gorenstein singularities. After a general discussion of the deformation theory, we specialize to dimension $3$ and consider examples which are good (log) resolutions as well as the case of small resolutions. We obtain some partial results on the classification of canonical threefold singularities that admit good crepant resolutions. Finally, we study a noncrepant example, the blowup of a small resolution whose exceptional set is a smooth curve.

Rethinking General Education from the Perspective of High School and Higher Education Curriculum Articulation
Authors: Hong Seongyoun
Published: November 2024

This study explores the concept of curriculum articulation between secondary and higher education, focusing on the continuity of curricula and their implications for foundational liberal education in universities. It analyzes the similarities and differences between general education at the high school and university levels. Both frameworks aim to cultivate holistic individuals equipped with essential competencies and a sound moral character through broad-based education. They share commonalities in historical origins, educational objectives, and curricular structures. However, high school curricula are typically organized around subject-based learning, whereas university curricula are more discipline-oriented, with pedagogical differences arising from the distinct roles of teachers and professors. These differences manifest in instructional content, teaching methodologies, and assessment practices. From the perspective of curricular continuity, sequence, and integration, the study advocates for the development of academically rigorous liberal arts courses at the university level that facilitate interdisciplinary mobility and integration for students, and the enhancement of teaching methods for interdisciplinary courses through ongoing faculty research. The conclusion suggests conceptualizing liberal education as encompassing three distinct domains: basic literacy education, liberal arts education, and experiential learning. It emphasizes that the scope of liberal arts education should extend beyond basic competencies, asserting that continuous faculty engagement and scholarly inquiry are essential for the effective development and refinement of liberal education curricula.
Studying an Integrated Reading-writing Education Method to Deepen the Humanities Thinking of University Students : Focusing on the ‘Questioning in the Form of Problem Discovery’ to Foster the Activeness and Creativity of Thinking
Authors: Shin Yunhee
Published: November 2024

The purpose of this paper is to explore the direction of humanities and liberal arts education at universities in the advent of the digital AI era, in which Generative AI invades human-specific areas due to the increasingly accelerated development of computer Internet technology, and to suggest what competencies learners need at this time and the contents and methods of education to cultivate them. Finding ways to coexist with digital AI technology, which has become a trend of the times, is a current task in the field of university education that needs to quickly respond to rapid social changes, adapt, and cultivate members of the future society. However, until sufficient research on this new media technology is done and its strengths and limitations are revealed in a relatively clear manner, I think it is necessary to examine and supplement the existing teaching methods that have already been developed based on sufficiently accumulated research and experience. Therefore, this paper proposed a reading-writing integrated education method that can shape the form and content of humanities thinking.

Authors: Park Soyoung
Published: November 2024

This study proposes a column-writing course model that utilizes public service advertisements (PSAs) and aims to elucidate the educational effectiveness and significance of the course through a survey conducted among learners. The study participants consisted of 99 learners enrolled in the course “Media Society and Critical Writing,” which is part of the mandatory liberal arts curriculum, , at Soongsil University. The course model is designed with the goal of analyzing various social issues presented in PSAs, collaboratively exploring solutions with peers, and ultimately completing a column. The design reflects Bransford et al. (1998) “IDEAL Problem Solving” method, the Engaged Learning+ approach implemented at Soongsil University, and the core competencies outlined by the World Economic Forum (2023). This paper aims to enhance learners' creative and analytical thinking, facilitate the establishment of social and self-awareness among students through their communication with others, and assist in articulating these insights in a column format. Additionally, a key design goal of this course model is to enable learners to concretely articulate the process of understanding and empathizing with the difficulties of others, which they may not have personally experienced, through the analysis of PSAs. The survey conducted among the learners revealed that this course model significantly contributed to improving their abilities in media text analysis, communication, and writing.
Characteristics and Challenges of AI Education in the Liberal Arts Curriculum of Domestic Universities : With Emphasis on the Linkage between the Primary and Secondary Education Curriculum and the Liberal Arts Curriculum of University in the Digital Transition Era
Authors: Song Sun Young
Published: November 2024

This paper aims to explore the characteristics and challenges of Artificial Intelligence (AI) education in the liberal arts curriculum of domestic universities. The revision of the curriculum to strengthen digital literacy has been in the field of the liberal arts in major universities. However, universities haven’t been aligning their curriculum with the core competencies developed in earlier stages. This has resulted in a disconnect occurring between AI education at the primary/secondary level and the university level. This gap can lead to students struggling to advance in AI-related topics as they transition to higher education. The liberal arts education of universities does not consider or reflect any linkage with the coherent system of the national curriculum, such as the 2022 revised national curriculum, of primary and secondary schools, which prevents the progress of students’ learning agency. For example, universities should take steps to open and run AI-related courses, regardless of government-supported projects, such as software (SW)-centered university projects. In fact, these project-based courses have not successfully addressed the need for a comprehensive AI and digital literacy education within the liberal arts. This paper, therefore, makes the following suggestions. Firstly, the liberal arts curriculum for AI education should restore its essence of humanity, preparing students to critically assess both the benefits and risks of AI in experiencing the digital transition. Secondly, universities should open and support AI-related courses in the liberal arts, ensuring that lecturers and professors receive the necessary resources to teach comprehensive AI education effectively.

Authors: Romero Hermes , Morales Juan Antonio
Published: November 2024

Purpose: To determine the effects of Kinesio Taping (KT) on physical performance in soccer players. Methods: A systematic search was conducted using the PubMed, Medline, and Web of Science databases. Inclusion criteria were randomized clinical trials; studies on healthy male and female soccer players aged 18-65 years; studies using KT. The search terms used were "(Kinesio Tape OR Kinesio Taping OR Kinesiology Tape OR Kinesiology Taping) AND (Football OR Soccer) AND (Performance OR Strength OR Balance)". All original studies published in English or translated to English from January 2014 to June 2024 were considered. Results: Six studies with a total of 172 subjects (all male, aged 18-31 years) were included. Three studies applied KT to prevent instability using functional correction techniques, on the knees and ankles. Five studies used KT to improve performance-related parameters using muscular strengthening/facilitation techniques, targeting the quadriceps, tibialis anterior, and iliopsoas muscles. Three studies showed significant performance improvements with KT, though two of these also included balance exercise protocols. Conclusions: While some studies demonstrated positive effects of KT on soccer performance, the evidence is not conclusive. More high-quality research is needed to definitively determine the effectiveness of KT for enhancing physical performance in soccer players.
Los orígenes de la pelota vasca y del boliche en Costa Rica (1899-1950)
Authors: Urbina Gaitán Chester Rodolfo
Published: November 2024

Este artículo aborda el siguiente objetivo: estudiar los orígenes de la pelota vasca y del boliche entre 1899 y 1950 para el primero y de 1901 a 1950 para el segundo. Para ello se reunirá la información que ofrezca los principales periódicos nacionales del período de estudio. El análisis de los datos obtenidos permite concluir que ambos deportes fueron practicados por una elite integrada por miembros de las colonias española, alemana y algunos de la burguesía, por lo que no fueron actividades al alcance de los sectores subalternos. Su ejecución se limitó a San José debido a que en esa ciudad existían locales adecuados para su enseñanza y competencia. Ambas disciplinas les permitieron la práctica a mujeres del grupo antes indicado debido a que ellas contaban con el capital necesario para comprar sus implementos deportivos y costear la afiliación a clubes deportivos exclusivos. Estos deportes experimentaron al final del período de estudio una decadencia en su práctica, debido a la crisis económica ocasionada por la Segunda Guerra Mundial y la polarización política que experimentó el país y que condujo a la Guerra Civil de 1948.

Purpose: The goal of the study was to evaluate the reproducibility between the application-replication of the electronic version of the WebCas questionnaire. Methods: The sample consisted of 152 students (10 to 15 years old) of both sexes, enrolled in a public school in the city of Curitiba (PR). Anthropometric data (weight and height) were collected to calculate the body mass index. The reproducibility of the questionnaire was assessed by means of concordance between the repeated measures obtained by applying the WebCas, with a 7-day interval between applications. Results: Most of the variables showed percentages of reproducibility above 50% (7/12 variables). Eight variables presented Kappa values considered “very good”: commuting to school (K=0.95); alcohol intake in the last 30 days (K=0.92); alcohol intake in doses (K=0.92); smoking (K=0.93); intoxication (K=0.92), nap (K=0.83), illness (K=0.94) and medication use (K=0.90). Daytime sleepiness, frequency of consumption of fruits, vegetables, sweets, snacks and soft drinks showed “moderate” Kappa values (0.41 to 0.65). Regarding accuracy, the variables hours of sleep, time to wake up on weekdays and bedtime on weekdays showed substantial values (>0.95 to <0.99). For the other variables, the values were almost perfect (≥0.99), with the exception of the variable “bedtime the night before” which showed low accuracy (Cb=0.90). Conclusion: The results showed that the WebCas questionnaire showed satisfactory evidence of reproducibility.
Intensive white shrimp (Litopenaeus vannamei) culture integrated with green mussel (Perna viridis), seaweed (Gracilariopsis bailiniae), and tilapia (Oreochromis mossambicus): impacts on water quality and growth of the shrimp

Published: November 2024

The production of Litopenaeus vannamei has significantly intensified, and integrated multi-trophic aquaculture (IMTA) has emerged as an effective farming technique to sustain the shrimp industry. Integrated aquaculture reduces pollution while increasing aquaculture production. This production system could give both ecological and economic benefits. Its contribution to the reduced amount of nutrients from intensive shrimp farming effluents and to the improvement of water quality conditions and growth of white shrimp are significant. This study aimed to evaluate the impacts on water quality and growth performance of shrimp (L. vannamei) at the same time assess the viability of rearing shrimps integrated with either green mussel, Perna viridis (GM alone), GM+seaweed (Gracilariopsis bailiniae), GM+tilapia (Oreochromis mossambicus), or GM+seaweed+tilapia. Shrimps were cultured outdoors for 60 days in a recirculating system at an average water exchange rate of 6 L hr-1. Shrimps were stocked at 400 shrimp m-3 in shrimp tank while seaweed (2kg m-2), green mussels (50 individuals per meter line), and tilapia (350 grams m-3) were cultivated separately in plastic baskets inside the biofiltration tank. Shrimp effluents were recirculated from the shrimp tank to the biofiltration tank. After 60 days of culture, results showed that shrimps without integration had the lowest average body weight (ABW), survival, weight gain, specific growth rate (SGR), biomass gain, and high feed conversion ratio (FCR) compared to shrimps with integration. This experiment confirmed that shrimp can be cultured intensively with either green mussel (GM alone), GM+ seaweed, GM+tilapia, or GM+seaweed+tilapia without adversely affecting the water quality and its growth performance and could even result in better yield than the shrimp cultured without integration. This research demonstrated the benefits of integrated aquaculture and could be further verified using large-scale culture.

Published: November 2024

Broiler chicken (Gallus gallus domesticus L.) production in Mexico is fundamental for contributing to food security since it is inexpensive and has a high nutritional value. However, given the insufficient national production of ingredients such as soybeans to obtain oil and make balanced foods, it has been necessary to import them, thus increasing the cost of raising broilers. In this context, sunflower seed (Helianthus annuus L.), due to its nutritional makeup, can be used to replace soybean meal and soybean oil in broiler diets. The purpose of this study was to evaluate the effect of partially replacing soybean meal and soybean oil in broilers’ diets with dehulled sunflower seeds on the physicochemical properties, fatty acid profile, and antioxidant capacity of meat. The experimental design was completely randomized: basal diet (sorghum-soybean meal); diet with 5 % sunflower seed and soybean oil; diet with 5 % sunflower seeds without soybean oil; and diet with 10 % sunflower seeds without soybean oil. There was no effect of the diet on the physicochemical characteristics (p > 0.05), but there was an effect on the fatty acid profile, which was better (p ≤ 0.001) in the treatments with sunflower seed, with or without soybean oil. The antioxidant activity in raw and cooked meat decreased after 9 and 6 days of refrigerated storage (p ≤ 0.05), respectively, without diet effect. Therefore, soybean meal can be substituted at 10 %, and soybean oil can be partially or completely replaced by dehulled sunflower seed in broiler diets as long as production parameters are not negatively affected.

Forecasting world crude oil prices needs to be done because it has an essential role in Indonesia’s economy, so an accurate and efficient forecasting approach is needed. This research combines heuristic and Fuzzy C-Means (FCM) models on Type 2 Fuzzy Time Series (T2FTS) to forecast crude oil prices. T2FTS, an extension of Fuzzy Time Series (FTS) by adding observations, is used to enrich the fuzzy relationship of the Type 1 model and can improve forecasting performance. FCM is used to determine unequal interval lengths and heuristic models to optimize fuzzy relations by identifying crude oil price movements using up and down trends. The data used in this study is the price of Brent crude oil as one of the benchmarks for world crude oil prices from 1 January 2023 – 31 May 2024. Mean Absolute Percentage Error (MAPE) measures accuracy in assessing forecasting results. The results showed that the combination of heuristic and FCM models in T2FTS gave accurate results, as evidenced by the MAPE value obtained, which was 1.50%, so it fell into the excellent category.

The rapid advancement of business in the seamless technology era has disrupted nearly every industry. Amidst this disruption, PT. Dayamitra Telekomunikasi (also known as/abbreviated as “Mitratel”) has encountered challenges, particularly an increasing rate of employee turnover. This turnover is thought to be driven by employee dissatisfaction with various internal and external company factors, along with low engagement levels. Previous research suggests that poor job satisfaction often results in higher turnover intentions, whereas strong employee engagement can help reduce turnover. This study explores the relationship between job satisfaction, employee engagement, and turnover intention at PT Dayamitra Telekomunikasi. The study employed a questionnaire based on an ordinal Likert scale, with data analyzed using the Partial Least Square (PLS) model, which doesn’t require a normal distribution and uses bootstrap techniques to examine correlations between latent variables. The results show that job satisfaction significantly impacts turnover intention, with 76.1% of job satisfaction indicators negatively influencing turnover intentions. However, employee engagement has minimal influence, with only 3.2% of engagement indicators affecting turnover intention. Therefore, while higher job satisfaction reduces turnover, employee engagement does not substantially affect turnover intentions. In summary, the study confirms that job satisfaction is crucial in lowering turnover intention, consistent with previous research, while employee engagement has a negligible effect on turnover rates.

In an increasingly competitive market, Geonusa, a geospatial service provider in Indonesia, faces challenges from price-sensitive competitors and low barriers to entry. This paper explores strategies to position Geonusa as a thought leader in the industry, enabling the company to differentiate itself and move beyond competing on price. By leveraging its expertise, fostering innovation, and strengthening its marketing and government relations, Geonusa can secure a competitive edge and improve its market presence. The paper discusses how adopting a thought leadership strategy can help Geonusa address current challenges in market visibility and customer retention. However, the strategy focuses primarily on marketing and does not comprehensively address cost optimization and operational efficiency, which are essential for long-term success.
Balancing Equity and Innovation of Japanese Corporate Governance
Authors:   Keio University, Kim Jungeun Elly
Published: November 2024

This paper critically examines Japanese corporate governance, evaluating its role as a benefit or constraint in achieving equity and efficiency. It contrasts Japan's stakeholder-oriented model, characterized by long-term stability and employee-centric management, with the shareholder-focused frameworks of the United States and the United Kingdom. The analysis focuses on the unique roles of CEOs in Japan, emphasizing their responsibility toward employee welfare over short-term financial gains. It further explores Japan's historical business structures, including Zaibatsu and Keiretsu, which foster interconnected corporate networks but limit flexibility and innovation. The relationship between firms and main banks within Keiretsu is analyzed, highlighting their role in financial oversight and stability. Additionally, the study addresses Japan's "Three Sacred Treasures" of labor-management relations—lifetime employment, seniority-based wages, and enterprise unions—as integral to its governance approach. Despite its strengths, Japan’s model faces challenges, including limited board independence and slow decision-making processes. Recent reforms aimed at increasing transparency and aligning with global governance standards are discussed, suggesting a shift toward a hybrid model that blends traditional stability with market responsiveness. This paper provides a comprehensive analysis of the evolving dynamics of Japanese corporate governance, offering insights into its impact on Japan’s global economic competitiveness.

Flexible Rent Payment Options for Tenants

Published: November 2024

The amount of pressure that tenants are experiencing to make timely rent payments has also influenced the need for flexible rent payment solutions. The conventional rental structures where tenets are expected to remit rent in full on the first of every month are also partial since many renters have irregular income patterns, such as those paid biweekly or weekly. These gaps have been further amplified by actionable factors such as the increase in living standards, volatility of income, and contract work. Analyses like the one conducted at the Joint Center for Housing Studies at Harvard show that most renters are "cost-burdened," paying more than 30% of their income on rent. This article also covers renters' financial vulnerability, including unstable income, disharmonization pay cycle, and sanctions for delayed rent, such as credit history deterioration, eviction, and damaged relations with a landlord. The discussion continues regarding the current payment solutions, such as third-party apps, auto-payments, and payment methods proposed by the landlord, with the pros and cons highlighted. Subsequently, the ability of flexible payment systems to mitigate tenants' cash stresses and prevent eviction is evaluated. The article also discusses the possibilities of future trends in rent payment flexibility, such as new technological advancements, implementation of subscription-based services, and changes in policies that can foster the improved utilization of flexibility in payment. Finally, tenants and landlords are given guidelines to guide individuals in the changing structure of rent payment choices and enhance living conditions.

Authors: Broadley Tania
Published: November 2024

Impending changes in Australian education brings forth the expected transformation of teachers working in schools. Three key points for transforming Australian schools has been identified by Gillard (2008a) including the improvement of quality teaching, ensuring every child benefits and mandating transparency and accountability. A number of initiatives were considered to assist with such reform including the implementation of a Digital Education Revolution, the move to the Australian Curriculum and the implementation of a National Framework for Professional Standards for Teaching. As these transformative initiatives are rolled out to teachers across Australia, the equitable access to PD to support all teachers, regardless of their geographical location, is in question. In line with the literature, the author proposes the concept of delivering PD and accessing PD from regional and remote areas be reconsidered. This research paper will outline the findings from the study including travel time being significant and impacting on teachers personal time; limited relief teachers impacting on access to PD; promotion and teacher registration being explicitly linked to PD; professional learning communities being valued but often limited by small staff numbers; professional learning conducted in the local context being preferred; professional learning established at the teacher and school level being desirable; teachers being confident in using technology and accessing PD online if required; and social cohesiveness being valued and often limited by isolation. Further this research has culminated in the development of a conceptual framework that would facilitate improving the amount and variety of professional learning available to regional and remote teachers.
