Occurrence and dietary risk assessment of AFB1 in tomato and pepper pastes in Türkiye
Authors: Aydemir Atasever Meryem , Özlü Hayrunnisa , Atasever Mustafa
Published: February 2025

Tomato and pepper pastes are essential ingredients in Mediterranean and Middle Eastern cuisines and contain beneficial health components. However, they may also contain toxic substances, such as aflatoxins. This study aimed to measure the levels of aflatoxin B1 (AFB1) in commercially branded and locally produced tomato and pepper pastes, and to determine the association between water activity (AW) and AFB1 contamination. Additionally, a risk assessment for AFB1 was conducted by calculating the estimated daily intake (EDI), margin of exposure (MOE), and hepatocellular carcinoma (HCC) risk. An evaluation of paste type (tomato or pepper) and source (branded or unlabeled) showed no statistically significant difference in AFB1 contamination (p>0.05). No statistically significant correlation was discovered between AW and AFB1 contamination in samples of tomato and pepper pastes (p>0.05). Evaluation of the data revealed that although the observed AFB1 levels were quite low, EDI, MOE, and HCC values were high. This may be due to the high daily consumption of tomato paste. Therefore, public health authorities must prevent AFB1 contamination in foods having high daily consumption. Legal limits of AFB1 contamination in such foods should be reduced as much as possible or not allowed at all.

Published: February 2025

Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare type of renal cell carcinoma (RCC) recognized as an independent entity in the latest WHO (World Health Organization) classification. We here report a case of a 51-year-old female patient with MTSCC, who presented with abdominal pain and left lower pole kidney lesion on the computed tomography scan. A robotic-assisted laparoscopic partial nephrectomy was performed. The diagnosis was confirmed on histopathological examination. MTSCC is rare and generally indolent. Either partial or radical nephrectomy is usually curative. The prognosis is usually favorable. However, occasionally, MTSCC could demonstrate aggressive features requiring systemic therapy. There are also several mimickers of MTSCC, which carry different prognostic and treatment profiles. Histological, immunohistochemical, and molecular genetic profile are useful in diagnosing the disease.

Son yıllarda kronik hastalıklar dünya genelinde önemli sağlık sorunlarından biri olarak ön plana çıkmaktadır. Çünkü bu hastalıklar nedeni ile her yıl milyonlarca insan hayatını kaybetmektedir. Ancak kronik hastalık ölümlerinin gelecek seyri net değildir. Bu nedenle, bu çalışmada BRICS-MT ülkelerinde her 100 bin kişiye düşen ölüm sayılarının 2035 yılına kadar tahmin edilmesi amaçlanmaktadır. Çalışma amacına ulaşabilmek için Institute for Health Metrics and Evaluation tarafından yayımlanan ölüm hızları istatistikleri dikkate alınmıştır. Verilerin analizinde ise 1970 yılında Box ve Jenkins tarafından zamansal veri analizleri için geliştirilen ARIMA kullanılmıştır. Çalışma sonucunda BRICS-MT ülkelerinde kronik hastalık ölümlerin önümüzdeki yıllarda da artarak devam edeceği belirlenmiştir. Özellikle Çin, Brezilya ve Meksika’da daha büyük artışlar olacağı tespit edilmiştir. Türkiye ve Güney Afrika için ise artışların daha sınırlı olacağı öngörülmektedir. Kronik hastalıkların toplum sağlığı ve sistem üzerindeki olumsuz etkilerini ortadan kaldırabilmek için ise eylem planlarının hazırlanması ve kronik hastalıklarla topyekûn mücadele edilmesi gerekmektedir.

1934’te kabul edilen Soyadı Kanunu, Cumhuriyet Türkiye’sinin kimlik dokusuna atılan kültürel bir mühürdür. Yeni kurulan Türkiye Cumhuriyeti’nin modernleşme ve millî kimlik oluşturma sürecinin en önemli adımlarından biri olan bu kanun, toplumun her bireyine bir soyadı kazandırarak, kişisel kimliği ulusal bağlamda güçlendirmeyi hedefler. Mustafa Kemal Atatürk’ün bu yasa doğrultusunda yakın çevresine verdiği soyadları Türk Milleti’nin köklerine ve kültürel mirasına işaret eden güçlü semboller olarak belirir. Her bir isim, Türkiye’nin geçmişine olan bağlılığıyla birlikte Cumhuriyet’in modern yapısını ve değerlerini yansıtır. Bu çalışmada, Atatürk’ün seçtiği soyadlarının etimolojik derinlikleri ve tarihsel arka planları incelenmiş; her bir soyadının, o şahsiyetlerin kimlikleriyle uyumu ve Türk Milleti’nin toplumsal hafızasındaki yeri araştırılmıştır. Soyadı Kanunu ile seçilen soyadları, yalnızca bir kimlik göstergesi değil, aynı zamanda Türkiye’nin yeni kimliğini şekillendirmede kullanılan önemli bir araç olarak kabul edilir. Özellikle seçilen adlar, Türk tarihini canlandıran, geçmişin izlerini geleceğe taşıyan anlamlarla yüklüdür. Atatürk’ün bu tercihleri, sadece bireysel kimlikleri değil, aynı zamanda milletin kolektif hafızasını da pekiştirme amacı taşır ve toplumda ortak bir aidiyet duygusu oluşturur. Bu isimlendirme tercihleri, yalnızca kişisel anılar değil, ortak bir geleceğe işlenen kültürel nişaneler olarak değerlendirilmektedir. Böylece, Atatürk’ün soyadı politikaları, Türk dünyasıyla kültürel bağları pekiştirmek ve Türkiye Cumhuriyeti’ne tarihî mirasla güçlendirilmiş bir kimlik kazandırmak için atılan bir adım olarak öne çıkar.

Authors: Khachikyan Kh.M. , Michenko A.V. , Topchyan A.P.
Published: February 2025

Histopathological knowledge of dermatologists and dermatological knowledge of histhopathologists and their cooperation help to more clearly diagnose and classify inflammatory skin diseases and skin cancers: it is no coincidence that they correlate positively and strongly. The fact is that the same pathology in different periods of its development is characterized by different, often complex, masking each other structural changes, which causes difficulties in differential diagnostics. Histological diagnosis is based on systematic analysis of pathohistological patterns. The pathohistological diagnosis of most inflammatory skin diseases is based on 6 pathohistological reactions: psoriatic (hyperkeratosis, acanthosis, parakeratosis, papillomatosis, etc.), lychenoid/ interface (compact orthokeratosis, diskeratosis, alternation of hyper- and hypogranulosis, lichenoid lymphocyte infiltration, vacuolar or hydropic changes in basal keratinocytes, etc.), spongious (intraepidermal spongiosis, exocytosis, neutrophilic and/or eosinophilic spongiosis, etc.), granulomatous (content of epithelioid and giant cells, asteroid and Schaumann bodies, necrobiosis, etc.), vesiculo-bullous (spongiosis, vacuolization, acantholysis, etc.), vasculopathic (inflammation of the vascular walls, hemorrhagic and ischemic changes of the vessels, infiltrative erythema, petechiae, purpura, nodules, livedo, etc.). The article considers dermatological and dermatooncological problems in the context of correlation of clinical and histological data with modern methods of optical skin diagnosis, which certainly increases the significance, especially for complex, dermoscopic, clinical and pathohistological evaluations.

Published: February 2025

Benign familial chronic pemphigus is a rare genodermatosis that has a significant impact on the quality of life of patients, currently incurable. Lack of unified clinical guidelines, diversity of methods of local and systemic therapy that do not give a pronounced long-lasting effect, cause researchers’ interest and necessity to find new therapeutic tactics for managing this disease. It is known that IgE-mediated pathological mechanisms promote degranulation of mast cells and basophils and stimulate Th2 immunity, that plays a leading role in creating protection against many diseases. It has been proven not so long ago that IgE autoantibodies are involved in autoimmune responses. Such autoimmune reactions include direct tissue damage, activation and migration of basophils to lymph nodes, and induction of type 1 interferon reactions, opening new possibilities for developing previously untried therapy methods. We present a series of clinical cases — 5 patients with benign familial chronic pemphigus of different localization, total IgE level above reference values (>100 mIU/ml), who positively responded to subcutaneous administration of omalizumab in a dosage of 300 mg on 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 42 weeks. Objective — to demonstrate the effectiveness of a new method for benign familial chronic pemphigus treatment in a series of clinical cases.

Published: February 2025

Objectives: The present investigation is devoted to analyzing the behavior of pressure and load carrying capacity of the hydrodynamic lubrication problem. The corresponding Reynolds equation of the considered hydrodynamic lubrication problem is acquired by the application of the Stokes equations of motion to the microcontinuum theory. This modification takes into consideration the couple of stress effects that arise from the combination of various additives with the lubricant. Method: The Daubechies wavelet multigrid method is used to find the solution of the non-dimensional Reynolds equation. Findings: Initially to validate the efficiency and accuracy of the proposed strategy, the test problem is considered. The findings of the test problems are presented in tables and captured in terms of the figures to ensure that the proposed method is more accurate and consumes less computational time as compared with the Finite difference method, Multigrid Method. Later, the effect of non-dimensional pressure and load carrying capacity for the considered geometry is calculated for varied parameters. Novelty: Most of the lubrication problems that are available in the literature are solved by the Finite difference method and this Finite difference method has errors (truncation and roundup) and also consumes a lot of time to find the solution. In order to overcome this, the multigrid method was introduced. Again to obtain more accuracy in the solution we used the Daubechies wavelet multigrid method. When a couple stress parameters changes from 0.0 to 0.2 pressure distribution increases to 111.03%.

Objectives: The focus of this article is to present the idea of employing complement, union, and intersection and examine these fundamental operations in both bipolar intuitionistic anti fuzzy (BIAF) ideals. We investigate the conditions of BIAF ideal and BIAF α-ideal of a BP-algebra in this research work. Comparing the fuzzy set to a bipolar intuitionistic fuzzy set revealed a definite result. Therefore, the concept of bipolar intuitionistic fuzzy set was defined as a combination of intuitionistic fuzzy set and bipolar fuzzy set. It provides useful outcomes for problem analysis. Methods: We provide the conditions for both BIAF ideals. We also give characterizations of a bipolar intuitionistic fuzzy (BIF) set. Findings: Implementing the fuzzy theory and ideal theory of a BP-algebra is the main aim of this study that can represent uncertainty and bipolarity in data. We consider the methodology as a concept of the BIAF ideals and discuss the operations. Novelty: The introduction of the BIAF ideals and the thorough examination of the basic operations constitute the research's uniqueness. In BIAF ideals, the study highlighted the concepts of complement, the union of two BIAF ideals and intersection of two BIAF ideals that can be investigated to provide more ﬂexibility in analyzing problems. This study is easy to understand, very effective, and appropriate for novices in a variety of professions. In this article, BIAF ideals play the major role with some basic operations. 2020 MSC: 03E72, 08A72.

Today, in Russia and globally, recycling of industrial waste is an extremely urgent task, the solution of which will enable the transition to a low-carbon circular bioeconomy and reduce the carbon footprint of anthropogenic impact. The goal of the research is to develop a technology for processing and utilization of pulp and paper industry waste containing synthetic polymers. It is carried out by their co-utilization in the form of combined fuel briquettes of the 2nd generation consisting of solid wood waste and laminated paper production waste, with subsequent utilization in a boiler plant with a low-temperature vortex furnace. The aim is to minimize harm for the ecological environment and increase the maximum energy and economic efficiency of industrial enterprises. To achieve the stated goal, the following research methods have been used: study of thermoplasticity of synthetic polymers and moisture plasticity of polymeric components of wood in the process of briquette formation, empirical determination of the optimal composition of combined briquette and properties of the obtained briquette using muffle furnace and calorimetric unit. The paper presents the results of the conducted research and experiments, in particular, the obtained values of density, strength, and calorific value of the obtained briquette at different compositions of feedstock. In case of the optimally chosen composition of raw materials in the fuel briquette, which is defined as the ratio of 50 % of solid wood waste and 50 % of laminated paper production waste, the final density is 1036 kg/m3, the average value of the lowest heat of combustion of fuel is 19 MJ/kg. Also, the compressive strength of 4,5 MPa has been determined under pressure on the cross-section of the briquette. The fuel briquettes obtained during the research have high indicators of density, strength and heat of combustion of fuel. The innovative technology of processing wood waste and waste packaging laminated paper will minimize harm for the environment and increase the maximum energy and economic efficiency of industrial enterprises. The use of the obtained fuel and the technology of its production will make it possible to reduce the load on landfills with currently unutilized waste and use the obtained fuel energy for own needs.
Multiparameter current protection against earth faults in 6–10 kV networks with isolated neutral

In distribution networks with a voltage of 6–10 kV operating with an isolated neutral, current protections based on monitoring the fundamental frequency component of the zero-sequence current are used for protection against single-phase earth faults (SPEF). The selectivity and stability of such protections are significantly affected by intense transient processes during arc intermittent SPEF. One of the promising areas to improve current protection against SPEF is to increase the selectivity and stability of their operation based on recognizing the types of earth faults using a multiparameter approach to implementing relay protection. To develop and study methods and algorithms to recognize types of earth faults in 6–10 kV networks with isolated neutral and to evaluate the efficiency of their application to improve the selectivity and stability of current protection against single-phase earth faults, simulation modeling in Matlab, SimPowerSystems and Simulink has been used. The configuration and parameters of the simulation models consider the key features of distribution cable and overhead networks with a voltage of 6–10 kV of industrial, urban, and agricultural power supply systems, determining the characteristics of steady-state and transient modes during single-phase earth faults. The principles of implementation and the scheme of multiparameter current protection against single-phase earth faults for 6–10 kV networks with isolated neutral have been developed. They ensure recognition of all considered types of earth faults (stable, arc intermittent faults and non-hazardous for the network arc faults) and the possibility of automatic selection of the most effective method of its operation (signal or trip action). Functional tests on simulation models have confirmed the efficiency of the developed algorithms of operation of multiparameter current protection for all considered types of single-phase earth faults in 6–10 kV networks with isolated neutral. The developed technical solution implements multiparameter current protection against earth faults ensuring increased selectivity and stability of operation for all types of earth faults compared to traditional designs of current protection against this type of damage, continuity of operation not only for stable, but also for the most dangerous arc intermittent earth faults, as well as the ability to select the method of protection for these types of earth faults.
Electrical system for converting vibration energy based on the combined operation of a linear generator and a magnetic fluid damper
Authors:   Ivanovo State Power Engineering University, Kazakov Yu.B. , Egorov I.S. ,   Ivanovo State Power Engineering University
Published: February 2025

Linear generators used as autonomous sources of electric power and electromechanical shock absorbers convert vibration energy into electric energy with a linear reciprocating motion of the inductor. The EMF of the generator has a non-sinusoidal shape due to higher spatial and temporal harmonics. The change in the speed of the inductor is determined by the nature of the acting forces, but during the analysis, it is usually taken as harmonic with a sinusoidal distribution of magnetic induction. Reduction of EMF harmonics is possible in an electrical system with a linear generator and a magnetic liquid damper, by improving the designs based on a refined analysis. The reduction of spatial harmonics of EMF has been achieved by improving the tooth zone and armature winding, using magnetic fluid. The reduction of time harmonics has been achieved by providing the electrical system with the necessary change in the linear speed of the inductor. The analysis has been carried out using the ANSYS Electronics Desktop, ANSYS MAXWELL and Elcut packages. An electrical system to convert vibration energy based on a linear generator and a magnetic liquid damper has been developed; its functions, features and operating modes have been described. The authors have developed combined device designs, a three-phase combined winding with an EMF increased by 2 % and a sinusoidal distortion coefficient reduced by 20 %. Mathematical analytical and numerical methods to calculate characteristics based on finite element modeling have been proposed. The developed electrical system allows efficient redistribution of vibration energy between the linear generator and the magnetic liquid damper and ensures reduction of higher harmonics in the EMF. The use of magnetic liquid controlled by a magnetic field allows us to regulate the resistance force to the inductor movement, to control viscous energy dissipation in liquid layers, to dampen vibrations, to increase the magnetic conductivity of the gap and the magnetic flux, to reduce the pulsations of the tooth harmonics of magnetic induction, to increase heat removal from magnets and winding, and to ensure efficient lubrication.

Воспалительная миофибробластическая опухоль тела матки представляет собой редкое новообразование, характеризующееся разнообразием морфологических проявлений и иммуногистохимического профиля. Большинство таких опухолей имеют благоприятный прогноз, однако в части случаев опухоль демонстрирует агрессивное поведение, рецидивирует и метастазирует. Экспрессия гладкомышечных маркеров усложняет дифференциальную диагностику с гладкомышечными опухолями, такими как гладкомышечная опухоль с неопределенным злокачественным потенциалом и лейомиосаркома. Экспрессия AL K в большинстве описанных случаев имеет важное диагностическое значение, однако пул ALK-негативных воспалительных миофибробластических опухолей может оставаться нераcпознанным. Представленный случай демонстрирует трудности морфологической диагностики воспалительной миофибробластической опухоли с доминирующим веретеноклеточным вариантом строения и невыраженным воспалительным инфильтратом. Точная диагностика имеет ключевое значение для выбора оптимальной тактики лечения, поскольку пациенты с агрессивным вариантом течения заболевания могут получать таргетную терапию ингибиторами тирозинкиназы.

The article also examines findings from Russian and Soviet studies on the effects of xenobiotics on the human body. Research on the acute toxicity of these substances peaked in the 1960s–1970s, while studies on their chronic effects began to emerge in the 1980s–1990s. Currently, such studies are extremely scarce.
Throughput-optimized channel assignment for random access wireless communication with and without collision resistance
Authors:   , Dutta Abhinanda , Weber Steven P.
Published: February 2025

The random access radio to channel assignment problem concerns the assignment of N homogeneous radios, operating in a common collision domain and with a fixed and common contention probability p, to M homogeneous channels so as to maximize the channel-average throughput. The throughput on each channel is the expected number of received transmissions in a time slot. Two cases are considered. The first case, termed collision loss, assumes that multiple transmissions in a time slot on a channel collide and are not received, i.e., a transmission is received when it is the sole transmission in the time slot on its channel; this is a classical model known as the collision channel. The second case, termed collision resistance, assumes the receiver is capable of multi-packet reception (MPR) in that it can receive up to K transmissions in a time slot on a channel but all such transmissions are lost when that number exceeds K. Evidently, the second case generalizes the first case, which corresponds to K = 1. The single channel throughput is nonlinear in the number of assigned radios -- it is initially increasing in the "underloaded" regime, reaches its global maximum, and then is subsequently decreasing in the "overloaded" regime. The assignment problem is a nonlinear combinatorial optimization problem. The problem is approached by integer relaxation: instead of assigning discrete radios to channels, the relaxed problem considers the assignment of a continuous quantity called load across the channels. This relaxation permits the use of classic techniques for the nonlinear optimization over continuous variables, e.g., Karush-Kuhn-Tucker (KKT) conditions. Numerical investigation of the accuracy of the solution of the relaxed problem to the solution of the combinatorial problem is limited by the combinatorial explosion of the search space for even moderate size problem instances, i.e., M and N, but the investigation suggests the solution of the relaxed problem yields channel-average throughputs that are close to those of the solution of the combinatorial problem. The assignment problem is of relevance in random access multi-channel wireless systems. Specifically, the proliferation of the Internet of Things (IoT) and the advent of massive machine-type communication (MMTC) have ushered in a new focus in wireless communication on enabling Low Power Wide Area Networks (LPWANs). LPWANs are specifically engineered to support a large number of low-power wireless devices operating over vast geographical ranges with low duty cycles. Among the LPWAN protocols, Long Range Wide Area Network (LoRaWAN) has emerged as a prominent solution, leveraging a multi-channel random access protocol to facilitate efficient communication.

Authors: Abdulloev A. M. , Gvozdev N. S. , Tropin D. V. , Popkov D. A.
Published: February 2025

Introduction Pediatric limb reconstruction associated with impaired osteogenesis and fragile bone suggests the use of combined techniques with telescopic intramedullary rods left in situ.

The objective was to test the hypothesis that transphyseal telescopic rods applied simultaneously with  an  external fixation device for pediatric femur or tibia lengthening associated with weak and brittle bone in  Ollier disease and osteogenesis imperfecta does not lead to the rod blocking during fixation, does not prevent distraction bone regeneration, lengthening and deformity correction.

Material and methods The study involved four male patients with Ollier disease and a female patient with osteogenesis imperfecta who underwent limb lengthening and/or deformity correction using a combined technique. Ilizarov apparatus was used as an external fixator, and a telescopic titanium rod was placed simultaneously with external fixator. With the bone consolidated, the Ilizarov apparatus was removed and the telescopic rod left in place.

Results The length gain and deformity correction intended were achieved in all patients. No loss of fixation of the threaded rod was observed in the femur and tibia epiphyses, or greater trochanter apophysis during distraction. There was no blocking of the rod telescopes during distraction. The external fixation index was 11.6 days/cm for polysegmental lengthening, 22.6 days/cm to 28.8 days/cm with monosegmental femoral lengthening.

Discussion Limb lengthening with a telescopic rod has the advantages of additional reinforcement through the segment with no risk of intramedullary construct migration as compared with combined lengthening techniques using flexible intramedullary nailing. There were no problems with formation of the distraction regenerate and longer period of external fixation, which can be seen with other techniques.

Conclusion Outcomes in this series indicated the possibility of limb lengthening and simultaneous osteosynthesis using external fixator and a telescopic titanium rod in patients with pathological osteogenesis. No loss of fixation of the threaded parts of the intramedullary rod, no blocking of the sliding parts of the rod were observed during limb lengthening.

Published: February 2025

Introduction Upper limb injuries sustained by children and adults with electric meat grinders in motion are mutilating. These injuries may lead to physical disability and severe psychological consequences not only for the injured subjects, but also for their family members.

Aim Based on current medical literature, to analyze the issues of incidence, etiopathogenesis, clinical symptoms, surgical treatment, rehabilitation, prevention of injuries to the upper limbs sustained with electric meat grinders and to illustrate the material with authors’ own clinical cases.

Material and methods The search for scientific publications was carried out in the electronic databases and libraries PubMed, eLIBRARY, CyberLeninka. The search depth was 47 years. In total, 49 scientific articles were analyzed and studied: 9 domestic sources (18.36 %) and 40 foreign ones (81.64 %).

Results and discussion Epidemiological data show that the incidence of injuries sustained by individuals while contacting with electric meat grinders in motion is 1.4 % to 11.1 % of open injuries to the upper limbs,. The main cause of this type of injury in children is the lack of control by adults, and in adults it is failure to comply with safety measures. The main mechanisms of trauma are traction and rotation. The right hand is most often injured, namely its fingers II, III and IV. Injuries are characterized by traumatic amputations, ruptures and crushing of hand segments. The most important goals of surgical treatment is excision of non-viable tissue, arrest of bleeding, shaping stumps of finger phalanges and metacarpal bones and / or osteosynthesis of  broken bones, suturing of vessels and nerves, the maximum possible closure of  the  soft tissue wound with preserved skin flaps. As preventive measures, it is proposed to inform the population on safety measures by operating electric meat grinders. There should be careful supervision by adults over young children if they are in places where food is prepared. Services of professional butchers are highly recommended.

Conclusion Based on data from 49 scientific articles, information was obtained on the frequency of occurrence, causes, mechanisms, clinical features, surgical treatment, rehabilitation and prevention of severe hand injuries sustained by individuals contacting with operation electric meat grinders.
Do monitoring agents strengthen the impact of founder and family boards on firm performance?
Authors: Suparman Meiliana , Jurnali Teddy , Lau Andy , Septiany Sheila
Published: February 2025

Research aims: This research aims to test the moderating effect of monitoring agents on the effect of the founder-board of directors (founder-BOD) and family-board of directors (family-BOD) on firm performance. Monitoring agents are represented by independent directors and commissioners. In this case, the age, size, and industrial type of the firms are the control variables.Design/Methodology/Approach: This quantitative research employed secondary data from 489 firms registered in the Indonesia Stock Exchange from 2018 to 2022. In this case, the observation data were 2,445, which were tested using a panel regression method. Research findings: Hypothesis test results show that monitoring agents strengthen the negative effect of founder-BOD on firm performance. Another result shows that family-BOD does not have a significant effect on firm performance, and monitoring agents do not show a moderating effect on the relationship. Theoretical contribution/Originality: This research provides new insights into the role of monitoring agents within Indonesia's two-tier governance system, enhancing our understanding of corporate governance in emerging economies. It offers a novel perspective on how independent directors and commissioners influence firm performance, contributing to the literature on corporate governance. Practitioner/Policy implication: The findings underscore the importance of enhancing the independence and effectiveness of monitoring agents to improve firm governance. These insights are relevant for policymakers and corporate governance reforms in Indonesia and similar emerging economies.Research limitation/Implication: Further research could consider the quality of monitoring agents, such as regulation, culture, social relationships, and knowledge.

Published: February 2025

Research aims: This study aims to determine the effect of human capital on the performance of VOEs through innovation capability and moderated by the accountability public on VOEs in the province of Bangka Belitung and West Sumatra.Design/Methodology/Approach: The sample consisted of 152 VOEs from West Sumatra and Bangka Belitung. Data were analyzed using SEM-PLS with SmartPLS 4.0. This quantitative study used primary data from questionnaires distributed to VOE management in both provinces.Research findings: The results show that Human Capital has a direct impact on the performance of VOEs and their innovation capability. The Innovation Capability also has a direct effect on performance. In addition, human capital affects VOE performance through innovation capability. Public accountability can weaken the innovation capability on performance.Theoretical contribution/Originality: This research is a development of previous research by adding public accountability as a moderating variable that can affect the quality of performance that is not present in previous studies. Practitioner/Policy implication: This study's findings suggest that the management of VOEs can improve service quality and human resources to create innovation and performance, which is important for local governments to create a supportive environment for VOEs innovation. Research limitation/Implication: The limitation of this research is that it only focused on VOEs in the Provinces of Bangka Belitung and West Sumatra. This research also only uses social desirability research instruments. Future research should expand the research scope, conduct research using interviews or other methods, and add other variables such as social capital and transparency.
From family control to female leadership: Enhancing anti-corruption transparency in Indonesian corporations
Authors: Barokah Zuni
Published: February 2025

Research aims: This study explores how family ownership and board diversity, particularly the presence of female directors, influence the extent of anti-corruption disclosures among the largest publicly listed companies in Indonesia and whether female board members affect the impact of family on the disclosures. Grounded in agency theory, the research posits that family ownership limits the transparency of anti-corruption disclosures. Additionally, drawing on upper-echelon theory, it is hypothesized that female directors promote more transparent anti-corruption reporting, thereby mitigating the negative impact of family ownership.Design/Methodology/Approach: This study analyzed a dataset of 443 firm-year observations from Indonesian non-financial companies between 2018 and 2023 and employed an OLS regression model that controls industry effects and uses robust standard errors.Research findings: The results reveal that family ownership is associated with lower levels of anti-corruption disclosure transparency. However, the presence of female directors on boards increases the level of anti-corruption disclosures, helping to counteract this negative effect and enhance transparency. Theoretical contribution/ Originality: This study contributes to the literature on anti-corruption disclosures and offers valuable insights into the governance implications of family ownership and gender diversity on corporate boards.Practitioner/Policy implication: The findings highlight the importance of promoting gender diversity within corporate leadership, as it can play a crucial role in improving governance quality, particularly in the area of anti-corruption disclosures.Research limitation/Implication: The study did not have many alternative family firm measurements because of the limited data in Indonesia. Family firm data is difficult to trace.
