Sadness and Loneliness in Adolescents with Physical, Sensory or Health Problems in Low/Middle-Income Countries.

Feelings of loneliness and sadness are increasing among the global youth, especially in disadvantaged settings. Young people with disabilities from low-income countries may be at greater risk of experiencing such emotions. This study aims to assess the dependence between difficulties/disability and sadness, loneliness and crying for no reason in young people from low- to middle-income countries and to test the risk of experiencing these emotions in young people with different disabilities versus the overall population. A cross-sectional study was conducted based on the Programme for International Student Assessment for Development survey, with 34,604 participants aged 15 years from seven countries: Cambodia, Ecuador, Guatemala, Honduras, Paraguay, Senegal, and Zambia. Dependent relationships were found between difficulties/disabilities and loneliness, sadness and crying. People with disabilities had a higher prevalence of these emotions. The probability of experiencing sadness, loneliness and crying was higher among people with difficulties/disabilities. Young people with disabilities in low-income countries are at a higher risk of experiencing feelings of loneliness, sadness and crying compared to the general population of the same age.

Inherited age of floating charcoal fragments in a sand-bed stream, Macdonald River, NSW, Australia: Implications for radiocarbon dating of sediments

Radiocarbon dates on multiple individual charcoal fragments floating together down the Macdonald River, New South Wales, Australia, have calibrated ages spanning >1700 years. Partial explanations of this range of inherited ages can be attributed to the inbuilt age of living biomass, charcoalisation conditions, hillslope transport and storage and/or valley floor (fluvial) transport and storage, but the contribution of each of these components can be constrained only rarely. These results caution against using radiocarbon dating of charcoal as the sole dating technique to interpret Late-Holocene sedimentary histories. These findings also show that it is unlikely that deposit age has a dependable relationship to charcoal age.

Investigation of a novel Couette flow with cylindrical baffles

The high-precision measure instrument for flow velocity is essential for industrial applications because the high-precision velocity can well reflect the physical characteristic of the flow. A restricted laminar Couette flow with cylindrical baffles, using a synthetic heat conduction liquid, was designed to obtain a steady vortex flow and wider work scope, according to Couette flow and Suspension flow characteristics. The heat transfer mechanism was investigated with a laminar flow model by the Fourier law. The research indicates that the heat transfer enhancement is related to the Temperature Boundary Layer (TBL). The TBL is affected by the Velocity Boundary Layer (VBL). The TBL thickness and Nusselt number (Nu) have a dependent relationship. The Reynolds number (Re) and the gap between the baffle and plate wall (Δh/h) can further affect Nu. The vortex flow generated by Couette flow can significantly enhance the heat transfer performance by a double spiral structure, which can rapidly mix heat fluxes and make the temperature converge to uniform. There is a sensitive and stable relationship between flow velocity and heat transfer. Notably, it is linear when Δh/h or Re is small, which can be used to design a high-precision thermal flow velocity meter.

Strategies to develop a sustainable and resilient vaccine supply chain in the context of a developing economy

Developing a vaccine supply chain (VSC) is an intricate process due to product perishability issues and cross-border supply complexities. On top of that, developing a pandemic-driven VSC is more challenging due to having significant operational, infrastructural, and policy-related disruptions. From the perspective of a developing economy such as Bangladesh, handling the global COVID-19 pandemic through the proper establishment of a VSC has been disrupted by a multitude of organizational, economic, and policy barriers. This has hindered the process of establishing a resilient VSC let alone ensuring the sustainability of the supply chain (SC). Therefore, this study strives to identify the key VSC strategies and their interrelationships under four groups: Intra-organizational, Inter-organizational, Legislative, and Environmental, based on previous literature and the expert opinions of industrial practitioners and policymakers. 20 strategies are ranked, and their causal relationships are discussed using the fuzzy DEMATEL method. This study utilizes the fuzzy set theory to deal with the vagueness of human beings' perceptions, and the DEMATEL method to form a structural model to find out the cause (influencing and independent) and effect (influenced and dependent) relationships among different strategies. The outcome of this study shows that ‘developing local production facilities for vaccines’, ‘creating extensive governmental policy to ensure efficient distribution of vaccines’, ‘ensuring sustainable investment in vaccine manufacturing and distribution’, ‘integrating advanced data analytics for robust and resilient demand prediction’ and ‘promoting public-private-people partnership for sustainable investment’ are the most prominent strategies. The findings provide stakeholders and policymakers with a practical framework for developing a sustainable VSC prepared for any virus outbreak, such as COVID-19, while also achieving the Sustainable Development Goals (SDGs).

Effect of International Political Developments on the Vietnamese Stock Exchange

This article examines how international political events have affected the volatility of Vietnam's stock market from 2010 to 2023. Through a statistical comparison of the VN-Index's volatility rate over time after political events, the research results have revealed three main trends. First, the VN-Index to fluctuate more strongly in the short term as it moves further away from the time of the event. Second, the volatility index changes depends on the dependent relationship of the place where the event occurs with the Vietnamese market. Finally, as Vietnam's stock market matures and moves further away from its establishment in the 2000s, the volatility of the VN-Index has decreased Keywords: International Political Events, Stock Market, Stock Market, Market Volatility.

Perioperative allogenic blood transfusions are associated with increased fracture related infection rates, but not nonunion in operatively treated distal femur fractures

IntroductionDistal femur fractures are common injuries that remain difficult for orthopedic surgeons to treat. High complication rates, including nonunion rates as high as 24% and infection rates of 8%, can lead to increased morbidity for these patients. Allogenic blood transfusions have previously been identified as risk factors for infection in total joint arthroplasty and spinal fusion surgeries. No studies have explored the relationship between blood transfusions and fracture related infection (FRI) or nonunion in distal femur fractures. Methods418 patients with operatively treated distal femur fractures at two level I trauma centers were retrospectively reviewed. Patient demographics were collected including age, gender, BMI, medical comorbidities, and smoking. Injury and treatment information was also collected including open fracture, polytrauma status, implant, perioperative transfusions, FRI, and nonunion. Patients with less than three months of follow up were excluded. Results366 patients were included in final analysis. One hundred thirty-nine (38%) patients received a perioperative blood transfusion. Forty-seven (13%) nonunions and 30 (8%) FRI were identified. Allogenic blood transfusion was not associated with nonunion (13% vs 12%, P = 0.87), but was associated with FRI (15% vs 4%, P<0.001). Binary logistic regression analysis identified a dose dependent relationship between number of perioperative blood transfusions and FRI: total transfusion ≥2 U PRBC RR= 3.47(1.29, 8.10, P = 0.02), ≥3 RR= 6.99 (3.01, 12.40, P<0.001), and ≥4 RR= 8.94 (4.03, 14.42, P<0.001). DiscussionIn patients undergoing operative treatment of distal femur fractures, perioperative blood transfusions are associated with increased risk of fracture related infection, but not the development of a nonunion. This risk association increases in a dose-dependent relationship with increasing total blood transfusions received.

Towards ‘bogus employment?’ The contradictory outcomes of ride-hailing regulation in Berlin, Lisbon and Paris

Abstract The issue of employment classification has been central in the politics around the platform economy. Crucial has been the phenomenon of ‘bogus self-employment’, whereby workers in de facto dependent employment relationships conduct services as independent contractors. Legislators around the world have aimed to tackle this issue by obliging platforms to classify their workers as employees. Based on empirical research in the ride-hailing industry of Berlin, Paris and Lisbon, where such classification exists already, we highlight its contradictory outcomes. We argue that platform companies have managed to introduce forms of ‘bogus employment’ whereby even formally employed workers lack basic worker rights.

IMPACT OF FINANCIAL LITERACY AND INVESTMENT SKILLS ON INVESTORS’ BEHAVIOUR IN COLOMBO STOCK EXCHANGE – MEDIATING ROLE OF DIGITAL LITERACY

"Rationality among the investors in decision making is essence for the performance of Colombo stock exchange (CSE) and also to development of country’s economy. Investor’s behaviour is unpredictable by any economist and even by equity market experts. Investor in the CSE can exhibit rational or irrational behaviour due to the multiple factors affecting investment. Therefore, study of investors behaviour is vital for improve the rationality among investors. As reviewed from literatures of many article, researchers found that, the increasing level of financial literacy and high level of practice in investment skills can improve the rationality of investment decision. The Covid-19 pandemic has driven in the explosive growth of ""Digital"" Financial Services (DFS) and online trading in CSE. Therefore, it is vital for the investor to familiar with digital advancement. Accordingly, Present study amid to analyse the impact of financial literacy and investment skills on investors behaviour and further carried the mediation analyse of digital literacy. Researchers point of view is “financial literacy teach investor to use money efficiently while, investment skills provide the ability to track, collect, analyse and research data to make decision in order to select the most profitable portfolio in CSE. However digital literacy is vital to apply the knowledge of Finance and investment skills in making investment decision in CSE”. This study conducted to identify the rationality of investor’s behaviour from assessing the impact of financial literacy and investment skills level of investors in CSE, and find the mediating role of Digital literacy. A self-administrated questionnaire was issued to the investors in CSE and 227 responses were collected via online. Present study adopted descriptive and inferential statistics to measure the independent- dependent relationship and Mediation relationship of the study. The findings revealed that, financial literacy and investment skills have impact on investor’s behaviour whereas digital literacy does not impact on investor’s behaviour. Moreover, findings revealed that, primal mediation of the study was insignificant accordingly there is no mediation predicted in present study.

The dependency‐autonomy paradox: A core‐periphery analysis of tourism development in Mediterranean archipelagos

AbstractDebates on island tourism have challenged the inevitability of underdevelopment in peripheral islands. A paradox of geopolitical dependency but optimal autonomy has been proposed where tourism can create a ‘virtuous periphery syndrome’. This study used a dependency theory lens and a core‐periphery framework to analyse stakeholders' perspectives on this, in two Mediterranean archipelagos. The most peripheral islands experienced the highest levels of environmental protection and lowest levels of development, which can be favourable for the development of tourism, but this was perceived as being constrained by dependent relationships. Problematic core‐periphery relations dominated tourism development in both archipelagos. Tourism can provide opportunities for island empowerment but local understanding of this must be developed for optimal autonomy through tourism to be achieved.

The Myth of Peace and Statehood in European Integration Theory: The Imperial Legal Order of the Rome Treaty

This article challenges the ontological assumptions of European Union (EU) theory that rest on the primacy of ‘states’. It also refutes the narrative of peace which is celebrated in scholarship and EU self-representation. It looks at early EU integration through the postcolonial lens and argues that both EU self-image and EU theory do not consider colonialism and empire and have silenced the violence committed outside Europe. Hence, they have produced a historically inaccurate and conceptually misleading account of early European integration. The post-colonial reading of the EU brings history back to the story of Europe to advance a revisionist account of theories of early European integration. The examination of arrangements laid out in Europe’s capitals – from Berlin in 1885 to Paris in 1919 to Rome in 1957 – reveals continuity of goals, motivations, and technologies of domination, rather than Europe’s ‘new beginnings’. The article demonstrates that the legal order established by the Treaty of Rome institutionalized the colonialism of EU members at the new supra-national level. It subordinated foreign people and economies to the interests of European capital, legitimized control of resources, camouflaged the old civilizing mission under a new guise of development, and reproduced and maintained the colonial racialized relationship of inequality and dependence. Ultimately, Rome infused the new European project with imperial, violent, hierarchical, and racial characteristics that remain unacknowledged by the EU theory.

Handling dependencies among performance shaping factors in SPAR-H through DEMATEL method

The Standardized Plant Analysis Risk-Human Reliability Analysis (SPAR-H) method is a widely used method in human reliability analysis (HRA). Performance shaping factors (PSFs) refer to the factors that may influence human performance and are used to adjust nominal human error probabilities (HEPs) in SPAR-H. However, the PSFs are assumed to be independent, which is unrealistic and can lead to unreasonable estimation of HEPs. In this paper, a new method is proposed to handle the dependencies among PSFs in SPAR-H to obtain more reasonable results. Firstly, the dependencies among PSFs are analyzed by using decision-making trial and evaluation laboratory (DEMATEL) method. Then, PSFs are assigned different weights according to their dependent relationships. Finally, multipliers of PSFs are modified based on the relative weights of PSFs. A case study is illustrated that the proposed method is effective in handling the dependent PSFs in SPAR-H, where the duplicate calculations of the dependent part can be reduced. The proposed method can deal with a more general situation that PSFs are dependent, and can provide more reasonable results.

The role of mother-child relationship in the association between maternal parenting stress and emotional and behavioral problems in preschool children

To study the moderating effect of mother-child relationship in the association between maternal parenting stress and emotional and behavioral problems in preschool children, and to provide reference for the prevention and control of emotional and behavioral problems in preschool children. Using a stratified cluster sampling method, 2 049 preschool children were surveyed from November to December 2021, who sampled from 12 kindergartens in Wuhu City, Anhui Province. The emotional and behavioral problems of preschool children were assessed with the Strength and Difficulties Questionnaire. Pearson correlation analysis was used to evaluate the relationship of maternal parenting stress and mother-child relationship with children's emotional and behavioral problems. The PROCESS Macro was used to analyze the moderating effect of conflicted and dependent mother-child relationships in the association between maternal parenting stress and emotional and behavioral problems in these preschool children. Among these preschool children, maternal parenting stress was positively correlated with the scores of emotional symptoms, conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001); intimate mother-child relationships were negatively correlated with the scores of conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001); conflicted and dependent mother-child relationships were positively correlated with the scores of emotional symptoms, conduct problems, hyperactivity, and peer problems subscales and total difficulty scores (P<0.001). After controlling for relevant confounding factors, conflicted mother-child relationship (β=0.05, P=0.001) and dependent mother-child relationship (β=0.04, P=0.012) were found to have a moderating effect on the association between maternal parenting stress and total difficulty scores in these preschool children. Negative mother-child relationships play a moderating role in the association between maternal parenting stress and emotional and behavioral problems in preschool children. Prevention of emotional and behavioral problems in preschool children should focus on reducing maternal parenting stress and improving negative mother-child relationships.

Association between immunoscore with lymphovascular invasion and clinical staging in colorectal cancer

Background: Despite the immunoscore benefit function as a prognostic tool in colorectal cancer, no study reports its reason. This study tried to identify the relationship between the immunoscore and the incidence of lymphovascular invasion and clinical stage in colorectal cancer patients as a mechanism for immunoscore to predict the outcome of colorectal cancer. Methods: This is correlational with a cross-sectional study that analyzed medical record data and laboratory results. Immunoscore was collected from an independent private laboratory, and other data (gender, age, diagnosis, tumor location, lymphovascular invasion) were from medical records from the Private Hospital colorectal cancers registry. Data collection was carried out from October to December 2022. We performed data analysis with the Chi-Square statistical test with a significant p-value&lt;0.05. Results: The results showed that the majority of subjects had tumor locations in the rectosigmoid (25%) and advanced stages (65%) with lymphovascular invasion findings (80%). Chi-Square statistical test shows the result of p = 0.025 and p = 0.64, respectively, lymphovascular invasion and clinical staging. Conclusion: This study shows that the immunoscore has a dependent relationship with the incidence of lymphovascular invasion and an independent relationship with the clinical stage of TNM in colorectal cancer patients. The application and use of immunoscore are beneficial for clinicians to give suggestions and understanding to patients about their choice of therapy also outcome for the patient.

High density polarization-induced 2D hole gas enabled by elevating Al composition in GaN/AlGaN heterostructures

A two-dimensional hole gas (2DHG) induced by polarization charges at the GaN/AlGaN hetero-interface is attracting much attention because of its potential to develop p-channel transistors required for GaN complementary logic integrated circuits. This platform is compatible with commercial AlGaN/GaN n-channel electronics, but the performance of GaN p-channel transistors has been far behind. In this work, 2DHGs in GaN/AlGaN/GaN heterostructures grown by plasma-assisted molecular beam epitaxy have been investigated. The Al composition of the AlGaN barrier has been pushed as high as possible without obvious strain relaxation, and the record high 2DHG sheet density and conductivity on the GaN/AlGaN/GaN platform have been obtained. By adopting a parallel conduction model, a dependent relationship of the 2DHG density on temperature has been extracted. The temperature dependent Hall-effect results have demonstrated that the 2DHG density boosts by 75 times and 46 times at room temperature and 77 K, respectively, when the Al composition is pushed from 0.18 to 0.45 for the AlGaN barriers. The 2DHG sheet density reaches 3.6 × 1013 and 2.1 × 1013 cm−2 at room temperature and 77 K, respectively, and the lowest sheet resistance is 8.9 kΩ/□ at 77 K. Such a 2DHG is beneficial for fabrication of p-channel GaN transistors with lower on-resistance on the already-industrialized platform.

Modeling the impact of tissue oxygen profiles and oxygen depletion parameter uncertainties on biological response and therapeutic benefit of FLASH.

Ultra-high dose rate (FLASH) radiation has been reported to efficiently suppress tumor growth while sparing normal tissue; however, the mechanism of the differential tissue sparing effect is still not known. Oxygen has long been known to profoundly impact radiobiological responses, and radiolytic oxygen depletion has been considered to be a possible cause or contributor to the FLASH phenomenon. This work investigates the impact of tissue pO2 profiles, oxygen depletion per unit dose (g), and the oxygen concentration yielding half-maximum radiosensitization (the average of its maximum value and one) (k) in tumor and normal tissue. We developed a model that considers the dependent relationship between oxygen depletion and change of radiosensitivity by FLASH irradiation. The model assumed that FLASH irradiation depletes intracellular oxygen more rapidly than it diffuses into the cell from the extracellular environment. Cell survival was calculated based on the linear quadratic-linear model and the radiosensitivity related parameters were adjusted in 1Gy increments of the administered dose. The model reproduced published experimental data that were obtained with different cell lines and oxygen concentrations, and was used to analyze the impact of parameter uncertainties on the radiobiological responses. This study expands the oxygen depletion analysis of FLASH to normal human tissue and tumor based on clinically determined aggregate and individual patient pO2 profiles. The results show that the pO2 profile is the most essential factor that affects biological response and analyses based on the median pO2 rather than the full pO2 profile can be unreliable and misleading. Additionally, the presence of a small fraction of cells on the threshold of radiobiologic hypoxia substantially alters biological response due to FLASH oxygen depletion. We found that an increment in the k value is generally more protective of tumor than normal tissue due to a higher frequency of lower pO2 values in tumors. Variation in the g value affects the dose at which oxygen depletion impacts response, but does not alter the dose-dependent response trends, if the g value is identical in both tumor and normal tissue. The therapeutic efficacy of FLASH oxygen depletion is likely patient and tissue-dependent. For breast cancer, FLASH is beneficial in a minority of cases; however, in a subset of well oxygenated tumors, a therapeutic gain may be realized due to induced normal tissue hypoxia.

How the UEFA Champions League divided Europe and harmed competitive balance within domestic leagues

ABSTRACT By fulfilling the gaps in the competitive balance literature in the sports industry and referring to Resource Dependence Theory, we analysed the mutually dependent relationship between UEFA and elite European football clubs, and precisely, elite clubs’ attempt to establish European Super League. Then, we examined the competitive balance within the top five European leagues and the UEFA Champions League and how unprecedented hegemony has occurred such that Juventus, Bayern Munich, PSG, Manchester City, and Barcelona won at least half of their national league titles in the last decade. Findings suggested that firstly participation rules and revenue distribution policies applied by UEFA in the Champions League may have harmed the competitive balance within national leagues. Secondly, increasing financial differences due to UEFA’s policies might also increase the power asymmetry between the top five and semi-periphery countries. Finally, we discussed what UEFA and football federations should do to eliminate these competitive disadvantages.

Extending Quality Function Deployment and Analytic Hierarchy Process under Interval-Valued Fuzzy Environment for Evaluating Port Sustainability

To confront the related problems of environmental protection, energy saving, and carbon reduction, sustainability has been a prominent issue for enterprises seeking to meet the requirements of the Earth Summit’ sustainable development goals (SDGs). Basically, sustainability evaluation of enterprises must be considered from environmental, social, and economic perspectives, recognized as quality requirements. Numerous enterprises, especially for international ports, must pay attention to these requirements in expressing their corporate social responsibility (CSR) for decreasing marine pollution. Practically, the three requirements may be dependent under uncertain environments, and rationally evaluated by fuzzy multi-criteria decision-making (FMCDM) with dependent evaluation criteria (DEC). In other words, evaluating port sustainability, containing location expanding, should belong to FMCDM with DEC. For DEC under uncertain environments, fuzzy extension of the analytic network process (ANP) is a feasible solution to solve the above problems. However, fuzzy computations of ANP are heavily complicated; thus, we desire to combine quality function deployment (QFD) with the analytic hierarchy process (AHP) under the interval-valued fuzzy environment (IVFE) into a hybrid method for evaluating port sustainability. In numerous multi-criteria decision-making (MCDM) efforts, AHP was often extended into FMCDM to encompass the imprecision and vagueness of data, but the extension was properly used for FMCDM with independent evaluation criteria (IDEC). Herein, QFD is utilized to express the dependent relationships between criteria, and thus transforms IDEC into DEC for the evaluation of port sustainability. Through the hybrid method, QFD is combined with AHP to replace ANP under IVFE, the complicated ties of ANP-corresponding interval-valued fuzzy numbers (IVFNs) are overcome, and the problem of evaluating port sustainability is rationally solved.

Estimating the probability distributions of radioactive concrete in the building stock using Bayesian networks

The undesirable legacy of radioactive concrete (blue concrete) in post-war dwellings contributes to increased indoor radon levels and health threats to occupants. Despite continuous decontamination efforts, blue concrete still remains in the Swedish building stock due to low traceability as the consequence of lacking systematic documentation in technical descriptions and drawings and resource-demanding large-scaled radiation screening. The paper aims to explore the predictive inference potential of learning Bayesian networks for evaluating the presence probability of blue concrete. By integrating blue concrete records from indoor radon measurements, pre-demolition audit inventories, and building registers, it is possible to estimate buildings with high probabilities of containing blue concrete and encode the dependent relationships between variables. The findings show that blue concrete is estimated to be present in more than 30% of existing buildings, more than the current expert assumptions of 18–20%. The probability of detecting blue concrete depends on the distance to historical blue concrete manufacturing plants, building class, and construction year, but it is independent of floor area and basements. Multifamily houses and buildings built between 1960 and 1968 or nearby manufacturing plants are more likely to contain blue concrete. Despite heuristic, the data-driven approach offers an overview of the extent and the probability distribution of blue concrete-prone buildings in the regional building stock. The paper contributes to method development for pattern identification for hazardous building materials, i.e., blue concrete, and the trained models can be used for risk-based inspection planning before renovation and selective demolition.

Mathematical modeling of strategic behavior: the Battle of Midway, 1942

In this paper, an innovative discrete dynamical model is presented, which is used to predict the kind of strategic behavior the participants should adopt to win a battle. For study purposes, a computer model is developed to reveal the most critical factors that strategically affect combat and the relationship of dependence between the warring parties. Besides, it can predict the outcome of a battle under specific scenarios. Furthermore, the proposed dynamical system is applied in Midway’s air–naval battle, which was one of the most decisive battles of World War II (WWII). It was a significant turning point in the history of naval warfare in the Pacific Ocean since the victory of the United States marked an end to Japanese expansionist policy, and these are the reason this battle was chosen. The numerical results of the analysis were presented, and the key factors (e.g., persons, decisions, and weather conditions represented by the critical values of model parameters) were highlighted, defining the outcome of the conflict.

Small-Scale Vannamei Shrimp Farm Business Sustainability Analysis With Micmac: A Study on Kebumen Coastal Area, Indonesia

Purpose: The objective of this study was to identify the internal and external factors of the sustainability of the vannamei shrimp farming business and the relationship of influence and dependence between the factors. Theoretical framework: Sustainability is required to create a balance between nature and humans for the use of coastal space in Kebumen Regency as a development area for the shrimp farming business to be carried out sustainably and provide sustainable benefits, as well as to preserve existing resources for long-term sustainability (UN, 2020). Development that ignores the interaction of the two results in price increases, which leads to a general decline in human welfare (Fauzi, 2019). This is to the global development agenda and the Sustainable Development Goals(SDGs)., which call for Indonesia to become a maritime axis. Design/methodology/approach: The research used a participatory method with semi-structured and in-depth interviews with the shrimp farming community and FGD. The data were analyzed using the sustainability analysis technique of Matrix of Cross Impact Multiplications Applied to a Classification (MICMAC). Findings: Identification of key elements in the sustainability of shrimp farming is essential to overcome and limit the risk of uncertainty caused by external and internal disturbances and pressures on shrimp farms. Government policy is a variable that has a strong and large influence on the sustainability of the shrimp farming business, and good government policy will enable the shrimp farming business system to reduce the pressure and threat of continuity. Research, Practical &amp; Social implications: Future research should focus on the management of shrimp farming and waste management to reduce the ecological, social, and economic impacts and the sustainability of shrimp farming that is environmentally and socially friendly. Originality/value: Government policy is a variable that has a strong and significant impact on aquaculture sustainability, with good government policies allowing the aquaculture system to reduce pressure and threats to shrimp. According to the facts on the ground, the shrimp farming business on the coast of Kebumen regency is operating independently due to a lack of attention, guidance, and policies governing the implementation of the shrimp aquaculture business.
