Authors: Xie Xinyu
Published: February 2025

This study focuses on the influencing factors of China's grain yield and utilizes econometric methods for in-depth analysis. A suitable econometric model is constructed by collecting data from various aspects, including total power of agricultural machinery, effective irrigated area, pure amount of agricultural fertilizer applied, sown area of grain crops and affected area indicators. The empirical analysis of the degree and direction of the influence of each factor on China's grain production shows that some factors, such as effective irrigated area and the amount of agricultural fertilizer used, have a significant positive correlation with grain production. The conclusions of the study help to understand the internal mechanism of China's grain production system, and provide valuable theoretical basis and data support for the formulation of scientific and reasonable agricultural policies to guarantee food security and increase grain production.
Empirical Analysis on Different Portfolio Management Strategies
Authors: Li Xiaoxi
Published: February 2025

This thesis examines portfolio management strategies, comparing optimization models with the equal-weight (1/N) strategy. A literature review highlights 1/N's robustness due to simplicity and reduced estimation errors, often outperforming complex models like Black-Litterman. The empirical analysis replicates the Black-Litterman 1/N model using 25-FF data, evaluating performance metrics such as Sharpe ratio and Omega measure. While Black-Litterman achieves lower volatility, 1/N outperforms in net returns due to lower transaction costs. The study underscores the importance of mitigating estimation risks and incorporating diverse asset classes to enhance advanced strategies, while highlighting 1/N's practical appeal in real-world applications.

Authors: Arriola-Ruiz Eduardo , Vázquez Guzmán David
Published: February 2025

Este trabajo busca indagar acerca de la relación entre la productividad de la manufactura y el nivel salario en México. Con pruebas estadísticas variadas, se obtuvo que, para los años seleccionados y de manera paradójica, entre mayor es la productividad de un sector en México le corresponde un menor salario promedio, particularmente en el sector industrial. Se comparó el salario promedio de entidades federativas diferenciando entre aquellas con alto y otras con bajo nivel de productividad y manufactura, a través de la construcción de un panel de datos con información oficial del Instituto Mexicano del Seguro Social y del Instituto Nacional de Estadística, Geografía e Informática (IMSS e INEGI) para el período 2007–2017. Se realizó una prueba−t de diferencia de medias para muestras independientes, y se construyó un modelo regresivo lineal con diferentes pruebas de robustez, donde concluimos que esta dinámica puede ser explicada por la brecha salario–productividad existente en el país, la automatización y por la heterogeneidad de la inversión en tecnología a través de los diferentes sectores productivos en las entidades de la federación

Authors: Handayani Nurma , Sari Shinta Permata
Published: February 2025

Achieving the Sustainable Development Goals (SDGs) requires support from business actors to address environmental degradation and climate change. This study aims to analyze the impact of SDG achievement influenced by Environmental Accounting, Material Flow Cost Accounting, Environmental Performance, and Environmental Cost in mining companies listed on the Indonesia Stock Exchange during the period of 2019–2023. The applied approach is quantitative, using purposive sampling, involving 70 companies as samples. Data processing was carried out using multiple linear regression methods. The findings of this study show that Environmental Accounting does not impact the SDGs, as its implementation remains formal and not fully integrated. In contrast, Material Flow Cost Accounting has an effect on the SDGs by improving resource efficiency and reducing waste. Environmental Performance impacts the SDGs, emphasizing the urgency of sustainable resource management and environmental protection. On the other hand, Environmental Cost does not influence the SDGs, indicating that the allocation of environmental costs by companies has not been optimally carried out. This research contributes to the development of the sustainability literature in the mining sector and encourages more effective environmental strategies. The practical implications of this study highlight the importance of implementing sustainability strategies to enhance corporate competitiveness and image, and it can serve as a basis for designing stricter regulations to promote environmentally friendly business practices and support the achievement of SDGs.

Authors: Situmorang Marissa Septyani , Ritonga Siti Hazzah Nur
Published: February 2025

In realizing the implementation of a smart city in Medan, the city government has introduced several applications. One such application is the SiBisa Application, which aims to facilitate the public in managing administrative documents online, allowing them to do so anytime and anywhere. This study aims to examine and describe the development of the SiBisa Application in realizing the smart city program by the Medan Civil Registry Office. This research adopts a qualitative approach, employing Merilee S. Grindle's (1997) capacity development model, which consists of three indicators: human resource development, organizational strengthening, and institutional reform. The findings indicate that (a) Human resource development at the Medan Civil Registry Office remains inadequate in terms of the number of personnel, resulting in suboptimal training and education efforts; (b) The establishment of specialized teams, such as the SiBisa Service Implementation Team (Operators and Verifiers) and an Expert Team, whose roles align with their respective expertise and procedures, serves as a supporting factor in organizational strengthening; and (c) Institutional reform at the Medan Civil Registry Office is reflected in the transition from manual to digital services. However, a lack of public understanding of the technology provided remains a challenge.

Literature Review: Policy Analysis on Exclusive Breastfeeding for Working Mothers
Authors: Husnul Khotimah  , Dumilah Ayuningtyas
Published: February 2025

Exclusive breastfeeding is an important part of fulfilling infant nutrition to achieve optimal growth and development in early life and subsequent growth. Some mothers cannot provide exclusive breastfeeding, especially working mothers. The purpose of this study was to analyze health policies on providing exclusive breastfeeding to working mothers. This study is a systematic review conducted in 2024 which was taken from the search site "google scholar". The articles selected after going through the process of identification, screening and determining the inclusion criteria were 9 articles. Working mothers face major challenges in providing exclusive breastfeeding to their babies. This challenge arises because of the conflict between work and family demands, busy work schedules, lack of flexibility, and inadequate lactation facilities in the workplace are the main obstacles, lack of social support from the surrounding environment also exacerbates the situation, stress due to work and family demands can affect breast milk production and make mothers feel uncomfortable while breastfeeding. However, with strong support from various parties, such as companies, families, and communities, working mothers can overcome these challenges and continue to provide exclusive breastfeeding. Comprehensive solutions are needed to address this complex problem, such as providing adequate lactation facilities, company policies that support breastfeeding, and socialization about the importance of exclusive breastfeeding.
Isoeugenol's biotransformation to vanillin using microorganisms
Authors: Verma Rupa , Dutta Abhijit
Published: February 2025

The biotechnological route of producing natural biological food products is preferred over synthetically created ones. One such pathway is biotransformation, which entails the chemical transformation of one substance into another using microorganisms acting as biocatalysts. One crucial process in green chemistry is biotransformation, which results in the biological production of numerous valuable chemicals. Due to its distinct aroma, vanillin is one of the most widely used flavors in the world. It is used in ice cream, cakes, biscuits, chocolates, and cosmetics. Compared to chemically synthesized vanillin, biologically produced vanillin has very few or no radicals, which is why it has very little or no negative effects on humans. Biological precursors such as eugenol and isoeugenol, as well as ferulic acids, can be utilized in the production of vanillin. Pure bacterial cultures were isolated from soil (isolates coded as DSH1001 to DSH1004) and identified by various biochemical reactions as Gram-negative rods. The microorganism identified by 16S ribosomal sequencing with accession number OR140859 can convert isoeugenol to vanillin. Their capacity to biotransform isoeugenol was also investigated. Using HPLC, a final screening of the selected bacterial isolate was carried out at a temperature of 37°C, pH 7.2, agitation rate of 150 rpm, and an initial isoeugenol concentration of 0.01%. The food sector can profit from the commercial production of vanillin by biological means.
Family Climate and Resilience: Coping and Growth When a Spouse and Co-Parent Faces Long-Term Severe Illness
Authors: Dor Asnat
Published: February 2025

This study examines how family climate supports one parent in coping with a spouse's long-term severe illness, focusing on the impact of family dynamics on coping strategies and personal growth. Such illnesses often disrupt family balance, creating stress for all members, with the healthy spouse relying on internal strengths and external resources.

The research addresses three key questions:

How can the coping process of the healthy parent be described when dealing with a partner’s long-term illness?
What family climate factors either hinder or support the coping process?
How do the meanings attributed to coping by the healthy parent relate to the family climate experienced during the illness?

A qualitative study, based on in-depth interviews with 16 parents (April–May 2023), identified two coping patterns: personal regression and growth. Participants highlighted family traits that either facilitated or hindered coping, emphasizing the interplay between family dynamics and individual responses.

Findings underscore the role of supportive family traits in fostering resilience and guiding individuals and families toward effective adaptation and growth during crises.
The impact of financial inclusion on poverty in the ASEAN-8 countries
Authors: Nguyen Trang Thi Thu , Tran Huong Thi Thu , Nguyen Ngoc Bich
Published: February 2025

One of the effects of financial inclusion in countries and regions is that it plays a significant role in poverty alleviation. This study analyzes the impact of financial inclusion on poverty in ASEAN-8 countries, including Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Thailand, and Vietnam. The authors employed panel data, which includes macro and micro annual data from 8 countries over 17 years from 2004 to 2020. The authors also do a thorough study of the impacts of different aspects of financial inclusion, such as the quantity of bank accounts, debit cards, credit cards, ATMs, branches, outstanding loans, and bank deposits. Using a random effects model, the study shows that financial inclusion, which is measured by a financial inclusion index, helps reduce poverty in the ASEAN-8 countries. Also, the main things that affect the negative relationship between financial inclusion factors and poverty are the number of bank accounts, the use of debit and credit cards, and the amount of money that people deposit in banks compared to their GDP. In addition, economic growth and government spending on education have negatively impacted poverty in these countries. The findings of this study provide practical implications for poverty reduction in the ASEAN-8 countries.
Entrepreneurial networking as a mediator between entrepreneurial orientation and business performance: Insights from small business owners in Malaysia
Authors: Sagita Ardio , Yusof Muhammad Suhaimi Mohd , Budiharjo Roy , Nsereko Isa , Suhimi Shyalwi
Published: February 2025

This research investigates the influence of entrepreneurial orientation on small business performance in Malaysia with the mediating effect of entrepreneurial networking. The responses from 146 business owners in the manufacturing sector were analysed using SPSS and Smart Partial-Least Square (PLS). The results showed that being innovative and proactive don't have a big impact on performance, but being independent, taking risks, and being competitively aggressive do. Contrary to the widespread belief about innovation and firm performance, this study highlighted possible cultural or regional effects of entrepreneurial orientation. Although limited in sample size, the results encourage further inquiry into variations within different markets. This may offer some benefits in terms of Malaysia’s small business success for practitioners and scholars as well, which accentuates the importance of entrepreneurial networking. Additionally, the findings suggest that fostering a culture of autonomy and encouraging risk-taking behaviours could be more beneficial for small businesses in Malaysia than previously thought. This insight is particularly valuable for policymakers and business advisors who aim to tailor their support strategies to the unique entrepreneurial landscape of Malaysia, and it could also serve as a focus for future research. Future research could explore these dynamics in other sectors and regions to build a more comprehensive understanding of how entrepreneurial orientation impacts business performance globally.
Debt policy score and performance score among energy companies: Empirical evidence
Authors: Aljaaidi Khaled , Alwadani Neef
Published: February 2025

The objective of this study is to examine the association between debt policy and financial performance among Saudi Arabian energy companies. The final sample consists of 18 firm-year observations listed on the Saudi Stock Exchange (Tadawul) from 2021 to 2023. This study used a quantitative-based method, and the data were hand-collected from the annual reports of the sample companies. The result of the Pooled Least Square regression (OLS) reveals a statistically significant positive relationship between debts and financial performance. This indicates that the higher the level of debt structure among energy companies in Saudi Arabia, the higher the performance they achieve. The energy companies use the debts as an external financing source to effectively and efficiently finance their investing activities. This finding backs up the trade-off and agency cost theories, which say that good debt management improves company performance by making the best use of capital structure. This study has implications for corporate finance decision-making in the energy sector, emphasizing the importance of balancing debt to foster financial growth. It contributes to the corporate finance literature by providing empirical evidence specific to the Saudi energy sector, highlighting both the benefits and complexities of debt policies. In specific, the results have significant implications for managers, investors, and policymakers regarding capital structure decisions and financial performance optimization.
Female CEO and firm performance in Vietnamese family business
Authors: Truong Khiem Dieu
Published: February 2025

This study examines the relationship between female CEOs and the performance of firms in the family business. The study uses 137 Vietnamese-listed family businesses on the Ho Chi Minh Stock Exchange from 2010 to 2022. The study indicates that the external female CEO is less likely to impact the financial performance of a business family because of their control over family members. On the other hand, the financial performance of the family business is significantly influenced by the relationship between the female CEO heir and the female CEO founder. The result of the study is consistent with the upper echelon theory and double standards of competence theory. Furthermore, the study employs the 2SLS model to strengthen the findings in situations involving endogenous factors. The result of 2SLS reconfirms the role of the internal female CEO in the family business, which indicates that there is a positive relation between the internal CEO and financial performance in the family business. Otherwise, there is no relationship between the external CEO and financial performance in the family business. The study illuminates the significance of gender diversity in the top-tier positions within family businesses. The result of the study contributes to the practical implications for the government, firms, and investors.
Investigating the effect of the shadow economy on Malaysia’s economic growth: Insight from a nonlinear perspective
Authors: Gamal Awadh Ahmed Mohammed , Salem Sultan Ali Mohammed , David Joseph , Tha Gan Pei , Viswanathan K Kuperan
Published: February 2025

Utilizing a nonlinear autoregressive distributed lag (NARDL) model, the goal of this study is to find out if the shadow economy's (SE) effect on Malaysia's economic growth is not linear from 1970 to 2022. This model uniquely identifies potential nonlinearities or asymmetries in the relationship between SE and growth. The results of the bounds tests show that there is a strong long-term link between economic growth and both good and bad changes in the SE, as well as variables like inflation, urban population growth in cities, financial development, and economic uncertainty. Furthermore, the results indicate that the SE’s influence on growth is nonlinear, both in the short and long term. In particular, both growing and shrinking the SE have positive effects on growth, but growing the SE has a bigger long-term effect than shrinking it. Conversely, in the short term, reductions in the SE’s size have a greater impact. Additionally, inflation, urban population growth, financial development, and economic uncertainties emerge as key determinants of growth across both time horizons. These findings suggest the need for policies that reduce the size of the shadow economy and encourage the shift from informal to formal economic activities to foster sustained economic growth.
Remittances and domestic investment in BRICS: Does financial development matter?
Authors: Tsaurai Kunofiwa
Published: February 2025

The study investigated the impact of remittances on domestic investment within the BRICS region. It also explored the complementarity effect (remittance and financial development) on domestic investment using the same data set. The existing literature shows a lack of consensus; hence, their findings are mixed, inconsistent, and divergent, and they show an absence of consensus. The study employed fixed effects, fully modified ordinary least squares (FMOS), and pooled ordinary squares (OS). Panel data used ranged from 1989 to 2020. Using personal remittance inflow per capita as a proxy, remittance’s influence on domestic investment was positive and significant across all three panel methods. When personal remittances received were employed as a proxy, remittance’s impact on domestic investment was significantly deleterious under the pooled OS. Financial development significantly improved domestic investment, as observed by Pooled OS (all three models) and FMOS (model 3). Pooled OS (model 1) and FMOS (model 2) produced results that show that financial development improved remittances’ ability to significantly improve domestic investment. The study shows that remittances are a critical element in enhancing domestic investment in BRICS. BRICS nations are urged to develop policies that enhance financial development and remittance inflow to improve domestic investment.

Authors: Manh Pham Tien , Linh Nguyen Do Tue , Linh Nguyen Ngoc Phuong
Published: February 2025

Vietnam's stock market is now highly developed and significant to the economy of the country. Many previous researches have studied the factors that affect stock prices on the stock market. Therefore, in this article, the authors examine the impact of stock liquidity on stock price crash risk with a sample space of companies on the Ho Chi Minh City Stock Exchange (HOSE) from 2016 to 2022. By using the linear regression research model, the authors found that stock liquidity has a negative impact on stock price crash risk. In this model, stock price crash risk will be the dependent variable, whereas stock liquidity will be the explanatory variable, which will ultimately determine the accuracy and suitability of the model through observed data. This topic provides considerable value to the depth of knowledge on stock liquidity and stock price crash risk in emerging markets and is helpful for emerging markets to monitor stock liquidity there. Additionally, this study offers potential strategies to manage stock price crash risk, which is valuable information for investors, authorities, regulators, and policymakers.
ROLUL ZINCULUI ÎN PROCESELE DE CREȘTERE ȘI DEZVOLTARE A PLANTULELOR DE PORUMB EXPUSE SECETEI FIZIOLOGICE
Authors: Brînză Lilia , Danilescu Olga , Bulhac Ion , Nedbaliuc Boris
Published: February 2025

The present work elucidated the effect of the new zinc coordination compound, with the formula {[Zn3(HL)2(H2O)6](SO4)2⋅1.5dmf∙2.5H2O}n (CCZn) (H2L=2,6-diacetylpyridine bis(isonicotinoylhydrazone), on the growth and development processes of seedlings of Zea mays L., the hybrid SY Ulises, exposed to physiological drought. The physiological drought was induced by adding the natural polymer polyethylene glycol (PEG6000) to the aqueous solutions. PEG6000 reduced the availability of water in the solutions and caused water stress to the seedlings. The experiments were carried out in laboratory conditions, and the research results showed that the CCZn has a positive effect in the early development of maize seedlings, both under favorable conditions and drought conditions. The significant physiologically beneficial influence of CCZn in the concentration range of 0.0001 – 0.01% was highlighted. In the early stages of seedling development, under moderate drought conditions, CCZn presents characteristics of a biologically active substance with anti-stress properties, evidenced by maintaining the growth and biomass accumulation of Zea mays L. plants at a significantly higher level than in the „control plant” variant.
În lucrare a fost elucidat efectul compusului coordinativ nou al zincului, cu formula {[Zn3(HL)2(H2O)6](SO4)2⋅1,5dmf∙2,5H2O}n (CCZn) (H2L=2,6-diacetilpiridină bis(izonicotinoilhidrazonă), asupra proceselor de creștere și dezvoltare a plantulelor de Zea mays L., hibridul SY Ulises, expuse secetei fiziologice. Seceta fiziologiă a fost indusă prin adăugarea în soluțiile apoase a polimerului natural polietilenglicol (PEG6000). PEG6000-ul a redus disponibilitatea apei în soluții și a provocat plantulelor un stres hidric. Experimentele au fost realizate în condiții de laborator, iar rezultatele cercetării au demonstrat că CCZn are un efect pozitiv în fazele incipiente ale dezvoltării plantulelor de porumb, atât în condiții favorabile, cât și în condiții de secetă. S-a evidențiat influența fiziologică semnificativă benefică a CCZn în intervalul de concentrații de 0,0001 – 0,01%. În fazele incipiente ale dezvoltării plantulelor, în condiții de secetă moderată, CCZn prezintă caracteristici de substanță biologic activă cu proprietăți antistres, evidențiate prin menținerea creșterii și acumulării biomasei plantelor de Zea mays L. la un nivel semnificativ mai ridicat decât în varianta „plante martor”.

Published: February 2025

The article presents an analysis of the stage-by-stage use of the protein electrophoresis method (as a key method of protein chemistry) in the selection and seed production of maize for the period 1988-2023 in the Republic of Moldova. The possibility of using a set of methodological developments (electrophoresis method and computer modeling principles) on a large volume of maize breeding and genetic material has been experimentally substantiated. This methodological complex helps to solve two important problems: the problem of exporting seeds of Moldovan breeding hybrids of maize and for a wide range of research work in the field of genetics and selection and seed production of Zea mays L. The analysis of the recent year’s results allowed the authors of this article to focus on the development and creation specifics of a catalogue of electrophoretic passports of new generation maize hybrids. The authors consider this catalog as a serious argument for the effectiveness of introducing modern methods of biochemical genetics and computer technologies into agronomic practice, which can be used successfully at the national and international levels.

70 jaar Statuut voor het Koninkrijk der Nederlanden. Verslag van het symposium van de Nederlandse Vereniging voor Rechtsvergelijking van 8 mei 2024

Het is inmiddels 70 jaar geleden sinds het Statuut voor het Koninkrijk der Nederlanden in het leven werd geroepen. Op 8 mei 2024 kwamen experts bijeen om met elkaar te spreken over de huidige staat van het Koninkrijk. Als student was ik daarbij aanwezig en in dit verslag heb ik de discussie neergeschreven. Het blijkt dat het Statuut breed gesteund wordt, maar dat er misschien ook verandering nodig is. De toekomst van ons Koninkrijk wordt ten dele bepaald door de toekomst van het Statuut. Een discussie daarover is dus fundamenteel.
