O texto a seguir dividido em três partes visa fazer, a partir de uma breve digressão histórica, onde elenco os elementos possibilitadores da compreensão de legado africano, cultura e patrimônio, situando os dois primeiros fora do close errado de tratar a maafa como o marco histórico dos povos africanos e o último dentro do seu bojo civilizatório que é o ethos euro-ocidental. Na segunda parte, O Legado Africano vem primeiro, faço uma discussão sucinta do conceito situando-o ao tempo que descrevo alguns trabalhos acadêmicos em seu bojo teórico. Em sua terceira parte, O conceito de patrimônio sob crítica no cruzo com Legados Africanos, subdivide-se em três seções. Em Contemporaneidades do patrimônio eu destrincho discussõoes contemporâneas ao respeito do patrimônio bem como de manifestações e conflitos em que ele seja o foco e, de outro lado, a seção Reimaginação onde estabeleço as conexões possíveis entre o legado africano e ilustrado na literatura pretafricana (quilombista). Na seção três, Um legado afro-jequieense, eu reinterpreto meus dados da pesquisa de mestrado dando centralidade ao desdobramento da categoria legado africano em legado afro-jequieense.

Authors: Portela Pablo Luís dos Santos , Factum Ana Beatriz Simon
Published: September 2024

O dendê, símbolo peculiar e relevante da culinária nacional, tem sido objeto de investigação em diferentes vertentes, e neste trabalho será abordado pelo campo da visualidade e da cultura baiana. Buscou-se evidenciar o histórico do dendê, a tipologia e a classificação da estrutura formal, bem como a sua validação na religião de matriz africana do Candomblé. Nesse sentido, observa-se a existência do dendê na cultura material e imaterial das pessoas, sobretudo da população baiana, que interage nos modos de viver, trabalhar, conceber imagens e repertórios. A metodologia adotada é a revisão de literatura que compreende a identidade cultural, a identidade baiana, a cultura e o cultivo do dendê, e seu simbolismo no âmbito sagrado, que se consolidou com pensadores centrais como Munanga (2020), Mariano (2009), Barreto e Freitas (2008), Bolini (2012), Lody (1992, 2009), Moraes e Pachêco (1985), Correa (2012), Oliveira (2009). Desse modo, conclui-se que o dendê é um elemento interdisciplinar presente em diversos contextos do cotidiano como na cultura, na arte, nas relações de fé, em produtos, as ações efêmeras e o imaginário coletivo.
Simbolismos étnicos afirmados através do matriarcado de mulheres negras de terreiros
Authors: De Santana Marise , Sales Oliveira Viviane
Published: September 2024

Neste artigo, embora estejamos focadas na etnicidade como forma de organização social de mulheres negras, lideranças de terreiro, que estamos chamando de Matriarcas, nosso propósito é pensar sobre como a tradição é mantida pelos simbolismos étnicos. Entendemos simbolismos étnicos, como saberes e fazeres materiais e imateriais, ensinados/aprendidos através de narrativas míticas geradoras de símbolos tradicionais e que para nós, como estudiosas dos legados africanos, nos interessa pensar sobre os conhecimentos das tradições afro-brasileiras, em especial, das mulheres que exercem o Matriarcado em muitos terreiros. Estamos falando em Matriarcado, correndo todos os possíveis riscos que esse debate traz. Estamos tomando Matriarcado para falar de mulheres, que nos aponta narrativas negras referenciadas em seus saberes, mitos e símbolos transmitidos por meio de cantigas, danças, rezas. Portanto, as Matriarcas, no movimento feito da “porteira para dentro”, mantêm as tradições refletidas nos saberes dos simbolismos étnicos ancestrais a respeito do feminino.  Da “porteira para fora”, como liderança religiosa, social e cultural, lutam contra as discriminações sexistas e raciais. Neste sentido, falar sobre o conhecimento da etnicidade que a Matriarca possui, a coloca no lugar de quem tem o conhecimento mais profundo da magia e do encantamento mobilizados pelo grupo étnico ao qual pertence.

Impact of Corporate Climate Change Performance on Information Asymmetry: International Evidence
Authors: Dey Sajal Kumar , Bose Sudipta , Luo Le , Shams Syed
Published: September 2024

In this study, we examine the association between climate change performance and information asymmetry using 6,367 firm-year observations from 2011 to 2020 across 26 countries. We find that climate change performance is negatively associated with information asymmetry, suggesting that firms with higher climate change performance tend to have lower information asymmetry. We also find that the negative association between climate change performance and information asymmetry is stronger for firms with a higher level of institutional ownership and better corporate governance. Further analyses show a more pronounced negative association between climate change performance and information asymmetry for firms domiciled in countries with stakeholder-oriented business culture, a national emissions trading scheme, and a higher level of climate change performance. Our study’s findings have significant implications for capital market participants, managers, policymakers, researchers, and practitioners worldwide in understanding the role of corporate climate change performance in the capital market.

Adrenal Dysfunction Caused by Critical Illness and Its Correction by Controlling Body Temperature: Prospective Cohort Study
Authors: Altshuler N. E. , Kruglyakov N. M. , Kutsyi M. B. , Popugaev K. A.
Published: September 2024

BACKGROUND. Critical condition (CC) is defined as any life-threatening condition that requires support of the functions of vital organs and systems to prevent imminent death. From the point of view of the course of CC and the survival of the patient, adequate functioning of the hypothalamic-pituitary-adrenal axis (HPA) is fundamentally important.

   AIM OF STUDY. To improve treatment outcomes for critically ill patients requiring temperature management through early diagnosis and timely correction of adrenal dysfunction.

   MATERIAL AND METHODS. Of the 59 patients, 45 (76.3 %) patients were diagnosed with adrenal dysfunction upon body temperature management (BTM) caused by critical illness: group I with vascular failure (VF+); in 14 (23.7 %) patients of group II adrenal disfunction wasn’t revealed (VF-).

   RESULTS. In group I (VF+) there was a high SOFA score, the highest number of days from the moment of illness to admission to the intensive care unit andinitiation of BTM, the presence of liver dysfunction, and a high level of C-reactive protein. Vascular failure in patients in group I developed earlier than other organ dysfunctions and sepsis. The high level of cortisol in the blood plasma in group II (VF-) was associated with the development of corticoresistance.

   CONCLUSIONS. 1. At body temperature management initiation, patients with adrenal dysfunction had a statistically significant high sofa score compared to patients without adrenal dysfunction (8 (5–9); 7 (6–8), respectively, p < 0,05). 2. The number of days from the disease onset to admission to the icu and initiation of body temperature management was statistically significantly high in the group with adrenal dysfunction compared to the group without adrenal dysfunction (20 of 45 patients (44.4 %); 4 of 14 (28.6 %) respectively, p < 0.05). 3. In the development of septic shock in patients with adrenal dysfunction, the criterion for the efficacy of the therapy was stabilization of the patient’s condition: positive hemodynamic response to the introduction of hydrocortisone with reduced doses of noradrenaline and its subsequent cancellation. 4. Despite the fact that the rate of organ dysfunction, sepsis and septic shock were statistically significantly higher (p < 0.05) in the group with adrenal dysfunction and the presence of vascular insufficiency, the performed treatment (hydrocortisone administration) allowed outcomes comparable to these in patients without adrenal dysfunction to be achieved (p > 0.05).

Authors: Kozlovskij B. V. , Arustamyan V. A. , Mikhaylov I. P. , Demyanov A. M.
Published: September 2024

INTRODUCTION. Despite the widespread use of methods for thermoobliteration of varicose veins, there are no standards for prescribing solutions for tumescent anesthesia when performing these operations. Existing prescriptions can be difficult, both in terms of finding the necessary components in a certain concentration, and in terms of correct dilution of the components in saline.

   AIM OF STUDY. To determine the reasonability of using complex medicinal prescription solutions for tumescent anesthesia when performing endovenous laser obliteration of varicose veins of the lower extremities.

   MATERIAL AND METHODS. The prospective study included 64 patients who underwent endovenous laser obliteration of the great or small saphenous vein. The operations were performed in accordance with the standard protocol on a device with a wavelength of 1,940 nm and radiation power from 5.0 to 6.0 W. Tumescent anesthesia was created using an automatic infiltration pump using 21 G needles with a length of 120 mm. Group I included patients (n = 34) who were anesthetized with a 0.1 % lidocaine solution at room temperature. Group II included patients (n = 30), for whom the anesthesia solution was prepared according to Klein’s standard prescription for tumescent anesthesia. The distribution of patients into groups was carried out using random sampling. Evaluation criteria: the presence or absence of complaints of pain during surgery and the level of pain assessed using a visual analogue scale.

   RESULTS. The groups did not differ statistically significantly in terms of main clinical and demographic indicators (p < 0.05). Complaints of pain or burning during surgery were made by 2 patients (5.9 %) in group I and 5 patients (16.7 %) in group II (p = 0.0023). The average pain value according to the visual analogue scale in group I was 0.75 cm [0.30; 1.44], in group II – 1.85 cm [0.85; 2.72], p = 0.0017, while in group I the maximum number of patients — 24 (70.6%) were distributed in the range of 0–1 cm, in group II the maximum number of patients, 17 (56.7 %) were distributed in the range of 1.5–3 cm according to a visual analogue scale.

   CONCLUSIONS. When using a simple 0.1 % lidocaine solution for tumescent anesthesia, a significantly lower average pain value according to VAS was obtained in comparison with the group of patients who used the standard D. Klein solution (0.75 cm and 1.85 cm, respectively, p = 0. 0017). Also, for the study group, a significantly lower frequency of perioperative complaints and complaints of severe pain was obtained (p < 0.01). The use of complex prescriptions of solutions for tumescent anesthesia when performing endovenous laser obliteration of varicose veins is impractical. The use of a simple 0.1 % lidocaine solution at room temperature, while following the surgical protocol, provides comfortable anesthesia.
Autosplenotransplantation After Splenectomy: Long- Forgotten Past or Promising Future?
Authors: Otdelnov L. A. , Dzhabadari V. V. , Mamedov I. Z.
Published: September 2024

AIM OF THE STUDY. To investigate the clinical and functional outcomes of autosplenotransplantation in cases of spleen injuries, and to establish its effectiveness in clinical practice.

   MATERIAL AND METHODS. Using the databases “e-library” and “PubMed”, a thorough review of national and international literature on autosplenotransplantation in patients with traumatic splenic injury was performed.

   RESULTS. This study analyzes literature sources to describe the technical aspects of autosplenotransplantation. The immediate outcomes of this operation show a low incidence of postoperative complications and good graft survival. In addition, this study presents the indications and contraindications of autosplenotransplantation. Comparing autosplenotransplantation to splenectomy, functional results indicate the best indices of humoral and cellular immunity and hemocoagulation. In the published literature, the functional activity indices of the transplant were comparable to those of healthy individuals with the functioning spleen. However, the studies yielding these results were conducted on small patient samples, limiting the reliability of the conclusions drawn.

   CONCLUSION. Autosplenotransplantation appears to be the only viable option for preserving the function of the lost spleen in patients with traumatic splenic injury who, for various reasons, cannot receive organ-preserving treatment. Large randomized studies are needed to assess functional results of the operation and, particularly, the immunological function of the transplant.

AIM OF STUDY. To describe a rare clinical case of surgical treatment of chronic recurrent dislocation of the forearm bones using the method of circular plastic surgery of the elbow joint ligaments.

   MATERIAL AND METHODS. In the conditions of the Department of Traumatology and Orthopedics on the basis of the Department of Traumatology and Orthopedics of the Federal State Autonomous Educational Institution of Higher Education “Russian Peoples’ Friendship University” in the V. M. Buyanov City Clinical Hospital of the Moscow Health Department, a comprehensive diagnosis and treatment of a 38-year-old patient with recurrent dislocation of the forearm bones was carried out. Clinical and radiological examinations including computed tomography and magnetic resonance imaging of the elbow joint were performed to verify the diagnosis. After a diagnosis of chronic posterior instability of the elbow joint was established, simultaneous plastic surgery of the medial and lateral ulnar collateral ligaments was performed using a single-loop circular autograft from the peroneus longus tendon.

   RESULTS. At a follow-up period of 12 months, a successful clinical result of surgical treatment with restoration of stability and function of the elbow joint was observed. Pain syndrome on the VAS scale decreased to 1 cm (before surgery 0 cm) with physical activity. The amplitude of active movements in the elbow joint after surgery was: flexion 140° (before surgery 135°), extension 5° (before surgery 5°), pronation-supination 150° (before surgery 160°). After surgery: QuickDASH score 26 (before surgery 44 points), OES score 72 (before surgery 45), MEPS score 85 (before surgery 55). MEPS was score 55, OES was score 45, QuickDASH was 44 points, QuickDASH (work section) was score 75.

   CONCLUSION. The method of tendon circular plasty of the elbow joint is an effective method of surgical treatment of multidirectional recurrent instability of the elbow joint, helps restore stability and function of the joint and does not lead to limitation of movements.

Authors: Novirani Dwi , Susanto Edi , Othman Norfaridatul Akmaliah , Gunawan Sri
Published: September 2024

Performance measurement regarding collaborative supply chain of fresh produces such as fruit and vegetables that combines vertical and horizontal collaboration structures is rarely found in the literature. Performance metrics in this lateral collaborative structure are useful for tracking and measuring the achievement of more comprehensive business goals that are not found in only vertical or horizontal structures. This research aims to explore and propose the best model for collaborative performance system (CPS) in the fresh produce supply chain (FPSC) and success factors in CPS implementation, including CPS metrics and matching collaborative individual performance (CIP) and supply chain performance (SCP). Papers from the last seventeen years including journal papers, working papers and conferences were selected in three steps. From 175 articles found in the first step, 63 articles matched the topic. In the third step, 48 articles were selected as important topics of discussion focused on the field of fresh products, with three classifications of collaboration structures and identifying CIP and SCP metrics which were then analyzed. The results of this review provide good opportunity as reference material for further research, through a comprehensive analytical description complete with a conceptual model presented to complete the gaps in this field. Keywords: Collaborative Performance System, Lateral Model, Performance Metrics, Rural Farmers, Supply Chain.

Authors: Mutawalli Muhammad , Zainal Amin Ayub  , Amah Emmanuel Ibiam
Published: September 2024

The purpose of this study is to find out the strengthening of the President's authority and identify polemics that have arisen related to the dissolution of ministries based on a review of Law Number 39, 2008. This study used a normative qualitative approach. The research was conducted at ministry and official agencies, as well as several activists at state studies institutions in the provinces of South-Sulawesi and West-Sulawesi. This research applies legal material collection techniques through documentation or literature studies and interview techniques. The results of the analysis show that in the process of forming a cabinet, good cooperation between the two institutions is needed to reach agreement and consensus. Intense communication and dialogue between the president as the head of the executive and parliament as the legislature helped to reach a consensus on the composition of the cabinet which was considered effective and capable of obtaining sufficient political support. The polemic that occurred was due to the lack of transparency in public participation, as well as collaboration between government agencies in the preparation and ratification of laws and regulations.

The present study was conducted to reveal and identify the epidemiological features of the fowl adenovirus species circulating in the Belgrade city area. The research included clinical examination, necropsy, pathohistology, enzymelinked immunosorbent assay (ELISA), and PCR analysis. Clinically, general weakness, increased conversion, and poor growth were observed. Postmortem examinations showed multiple necrotic foci in the liver, and swollen and pale kidneys. Pathohistological examination of the liver revealed hepatocellular necrosis, vacuolar degeneration of hepatocytes, cholestasis, and hyperemia. Serological analysis of 210 blood sera confirmed seroconversion in 156 (74.28%) samples against FAdVs, and depending on the farm, it ranged from 23.33 to 100%. Using the PCR method, 105 cloacal swabs were analyzed to determine the virus genome found in 31 (29.52%) samples. Hexon gene sequence analysis identified two species: fowl aviadenovirus D (serotype FAdV-2, FAdV-11) and fowl aviadenovirus E (serotype FadV-8b). Those species are closely related to strains circulating in Hungary, Turkey, and other countries. Our findings suggest that FAdV strains are significantly prevalent and could be an emerging pathogen in Serbia.
Dreams and Time. A Phenomenological Analysis
Authors: GRIGORESCU Crina
Published: September 2024

Dreams are a complex phenomenon which the philosophical field knows very little about. However, scientists like Freud or Jung, were able to prove that dream interpretation brings different advantages to our lives. For that reason, the purpose of this paper is to demonstrate that dreams, when understood, can offer us a new life perspective, especially in difficult times.
Therefore, with the help of an innovative phenomenological approach introduced by Maria Zambrano, which focuses on the form of the dream and its relation with time perception, rather than the dream content, we are going to observe that people have many types of consciousness, as well as different forms of access to time which relate to multiple perception modes and emotional states. Applying this theory, Maria J. Neves, is able to demonstrate that a phenomenological dream analysis can produce significant changes in peoples’ lives.
O legado clássico de Horácio em Sá de Miranda e Ricardo Reis
Authors: Santos Ribeiro André Luís , De Castro Soares Maria Luísa
Published: September 2024

In Portuguese literature, revisitations of Classical Antiquity, particularly the Greek philosophical doctrines of Stoicism and Epicureanism, as well as the literary genres cultivated in Latin literature by Horace, are projected onto Sá de Miranda, in the Renaissance period, and onto the modernist avant-garde heteronym of Fernando Pessoa, Ricardo Reis. Themes such as carpe diem, exegi monumentum, and non usitata, in the manner of Horace, are reactualized in the works of Portuguese poets. The aurea mediocritas, the awareness of the inexorable passage of time, and the conception of utile et dulce are constant thematic and theoretical elements that resonate in Sá de Miranda and Ricardo Reis, although modified by the reasons of time. To carry out this study, hermeneutic and comparative methods of analysis are applied to the works of Sá de Miranda and Pessoa in order to scrutinize the similarities and differences of the authors with Horace.

Authors: Kassim Muhammad Asyraf Mohd , Hassan Md. Sharif , Amin Mohammad Bin , Abdullah Muhammad Safizal , Salahudin Shahrul Nizam , Illés Csaba Bálint
Published: September 2024

Road accidents involving motorcyclists significantly threaten sustainable mobility and community safety, necessitating a comprehensive examination of contributing factors. This study investigates the behavioral aspects of motorcyclists, including riding anger, sensation-seeking, and mindfulness, which play crucial roles in road accidents. The study employed structural equation modeling to analyze the data, utilizing a cross-sectional design and self-administered questionnaires. The results indicate that riding anger and sensation-seeking tendencies have a direct impact on the likelihood of road accidents, while mindfulness mitigates these effects. Specifically, mindfulness partially mediates the relationships between riding anger and road accident proneness, as well as between sensation-seeking and road accident proneness. These findings underscore the importance of effective anger management, addressing sensation-seeking tendencies, and promoting mindfulness practices among motorcyclists to enhance road safety and sustainable mobility. The insights gained from this research are invaluable for relevant agencies and stakeholders striving to reduce motorcycle-related accidents and foster sustainable communities through targeted interventions and educational programs.

Authors: Alharbi Bandar Fahad
Published: September 2024

Throughout the course of a project cycle, the many phases of project management—including planning, execution, control and monitoring, and ending—are integrated and executed. In modern firms, project management has become the dominant tool for managing change. Best practices have emerged due to global project management practices and company evolution. The primary goal was to investigate how project management approaches affected project performance of the Saudi Arabia Small and Medium Sized Enterprises (SMEs). This study investigated the impact of various project management practices including risk management, communication, leadership, and stakeholder management, on project performance in manufacturing SMEs in Riyadh, Saudi Arabia. A quantitative research methodology was employed, with data collected from 250 employees (i.e., supply chain, finance and R&D managers/supervisors) across 8 SMEs. The results revealed that risk management, leadership practices, and stakeholder management significantly contribute to project performance. Surprisingly, no significant relationship was found between communication practices and project performance. The findings of this study emphasize the importance of effective risk management, strong leadership, and efficient stakeholder management in achieving successful project outcomes. Finance managers and R&D managers in Saudi manufacturing SMEs should lead and engage stakeholders to improve project performance. Supply chain managers must manage risk and maintain stakeholder relationships to avoid disruptions. Communication improvements, despite their small impact, are essential for departmental coordination. Global project management strategies tailored to local culture and business will improve project success.

Authors: Lihoussou Messan , Badou François de Salle Mahoutin , Kploguede Sena Roland
Published: September 2024

African air transport is expected to take off after the Single African Air Transport Market (SAATM) launch in January 2018. Unfortunately, this seems not to be the case, particularly in West Africa, where adequate direct local flight is highly difficult to find. Hence, the fundamental question is: what levers should be activated for an effective revival of this sector? This paper aims to analyze West African air transport competitiveness factors by collecting data physically through surveys in various West African airports (Abidjan, Cotonou, Accra, Lome) also by interviewing professionals in the sector (Air traffic controllers, Air Navigation Service Providers, Air transports Managers, etc.) and among others, SAATM reports to appreciate its implementation. We were able to survey 435 actors (individuals and key informants) from January to July 2023 to evaluate quality of service, airline performance, safety, customer satisfaction etc. Airline operating costs were analyzed to understand the associated bottlenecks. The results show that SAATM is not yet well implemented in all contracting states, travelers are not satisfied with the air supply (airlines, infrastructure and fares) and taxation excessively increases ticket prices. The main factors for West African air transport take-off are liberalization, taxation and infrastructure investments.

Published: September 2024

The rise of fintech in the financial sector presents a transformative shift towards digitalisation and sustainability on a global scale, leveraging technologies like AI to minimise environmental footprint. Neobanks not only challenge traditional banking models but also offer innovative solutions that align with sustainable objectives. The purpose of this paper is to analyse the impact of neobanks on global sustainability from economic, environmental, and social points of view. A comprehensive literature review of existing literature and current sustainable practices of neobanks was conducted. Results reveal that neobanks significantly positively contribute towards environmental sustainability with reduced paper use and logistics requirements of banking services. By offering more accessible and affordable banking services they importantly contribute towards higher financial inclusion, and with innovative products towards more competitive and innovative financial markets. AI-based tools they employ are increasing financial literacy and social inclusion. This article also highlights concerns regarding electronic waste management, potential high energy consumption, required digital literacy and cybersecurity risks. In conclusion, despite the mentioned risks, neobanks importantly contribute to global sustainability in many ways and will even more in the future. These findings can help neobanks shape sustainable practices and guide policymaking, as well as spread awareness of the sustainable impact of banking services.

Authors: Zhang Pengfei , Jing Xianwu , Zhou Lang , Liu Qiang , Zhang Yadong
Published: September 2024

Methoxypolyethylene glycol 1900 and α-bromoisobutanoyl bromide were utilized for alcoholysis reaction to obtain a macromolecular initiator. Then, a simple amphiphilic diblockpolymer (mPEG-PDMAEMA) based on the initiator and dimethylaminoethyl methacrylate was synthesized through the atomic transfer radical polymerization (ATRP) method. The structures of the initiator and diblock polymer were accurately characterized using infrared spectrum and proton nuclear magnetic resonance spectroscopy (1H NMR). Cryo-transmission electron microscopy revealed the self-assembly of mPEG-PDMAEMA into vesicle-like structures in water. Upon injection of CO2 into the solution, the tertiary amine structure within PDMAEMA underwent protonation, resulting in the mPEG-PDMAEMA adopting a hydrophilic structure. Consequently, the vesicles dissociated and dispersed, forming a network-like structure in water. The protonation phenomenon was confirmed by 1H NMR, as evidenced by the shifting of alkyl hydrogen atoms near nitrogen atoms toward downfield positions.

Published: September 2024

The preparation of composite metal oxide to attain high efficiency in removing phenol from wastewater has a great concern. In the present study, the focus would be on adopting antimony-tin oxide coating onto graphite substrates instead of titanium; besides the effect of SbCl3 concentration on the SnO2-Sb2O3 composite would be examined. The performance of this composite electrode as the working electrode in the removal of phenol by sonoelectrochemical oxidation will be studied. The antimony-tin dioxide composite electrode was prepared by cathodic deposition with SnCl2 . 2H2O solution in a mixture of HNO3 and NaNO3, with different concentrations of SbCl3. The SnO2-Sb2O3 deposit layer’s structure and morphology were examined and the 4 g/l SbCl3 gave the more crystallized with nanoscale electrodeposition. The highest removal of phenol was 100% at a temperature of 30 oC, with a current density (CD) of 25 mA/cm2.

Islamic boarding school-based economic development leverages these schools to drive an independent economy through business units. This research aims to assess economic growth in West Java’s Islamic boarding schools using qualitative descriptive methods, which outline factual situations and problems. The study found several Islamic boarding schools in West Java operate business units, including cooperatives, building rentals, and Santri Marts. However, economic development is slow due to limited business expertise among staff and the reliance on profit-sharing for business management, reducing the need for extensive control. Historically, Islamic boarding schools have focused primarily on education and religion, but since the 1970s, some have started to address social issues, including economic and political challenges. With 4,328 Islamic boarding schools and over 5 million students in West Java, there is significant economic potential. To harness this, the West Java Islamic Boarding School Cooperative Center (Kopontren) and the West Java Regional Office of the Ministry of Religion (Kemenag) organize business internships for 204 students. Empowering these schools through economic development can create greater independence and effectively leverage the vast student population.

A firm's market value is a vital measure that encapsulates its overall operational performance and appeals to investors. Optimizing the capital structure can enable companies to bolster their value proposition and appeal to investors. This study investigates the relationship between capital structure and firm value, with the potential for dividend policy to act as a moderating factor. Comprehending the interplay between these elements is crucial in shaping the company's capital decisions and their subsequent impact on enhancing its market value. The research was conducted online through the official website of the Indonesia Stock Exchange, focusing on all Consumer Goods Companies listed on the IDX from 2020 to 2022. Purposive sampling was used to determine the study's sample. The analysis employed linear regression and moderate regression analysis methods with the assistance of SPSS for Windows statistical application. The findings suggest that capital structure does not affect firm value. Interestingly, this result implies that dividend policy may diminish the impact of capital structure on firm value. These insights underscore the significance of aligning funding strategies with appropriate dividend policies to maximize firm value and appeal to investors.

Authors: Khairurrizqo Khairurrizqo
Published: September 2024

Indonesia entered the era of political reform after the collapse of the Soeharto in 1998, which was marked by an agenda of government reform, including reform within the military. Reforms and dismantling of the dual-single doctrine (Dwifungsi) brought the army back to the barracks, and regulations ensured the army focused on its duties as guardians of national defense. Later in Indonesia's political process, informal military groups played a role behind the scenes as part of the team that formulated strategic policies. This research analyzes the development of military reform and influence in Indonesia from the reign of BJ Habibie to Joko Widodo and the factors that influenced the development of military reform. This paper uses a qualitative approach to describe the informal power of military groups in the political turmoil in Indonesia. This article uses data collection techniques in the form of documentation studies with a content analysis approach from various studies and news. The informal political power of the military group had a different impact on numerous policies of the President of Indonesia after the reformation. In the era of President BJ Habibie, the military still dominated, although the president later gave limits, especially to stop the Dwifungsi ABRI principle. In the Abdurrahman Wahid era, the influence of informal groups declined relatively due to Gus Dur's frontal policies to enforcing human rights. During the Megawati era, retired military officers strengthened the military's influence in Benny Moerdani's circle of influence. Under SBY, the influence of informal groups can be seen in his efforts to revoke TNI's business units entirely in various fields. The influence of informal groups returned in President Jokowi's era with his policy of recruiting retired military generals in various strategic posts in civilian ministries.
