Towards a Standardized LCOE Calculation for Informed Decision-Making in Energy Policy and Investment: Application to the Colombian Context

The Levelized cost of electricity - LCOE represents a constant cost per unit of generated electrical energy, resulting from the analysis of the total costs throughout the life cycle of a generation plant. Its widespread use, thanks to its simplicity of calculation and potential of standardization, has made it one of the primary criteria for comparing electricity generation technologies. However, in the pursuit of simplification and generalization, certain aspects associated with the socioeconomic context of the region, as well as accounting and financial concepts, are excluded due to externalities or incentives related to regulatory and fiscal policies. These exclusions affect the accuracy of LCOE and introduce uncertainty when using it as a criterion for investment decision-making or allocation of public resources for the development of renewable sources. This article proposes a clear and standardized methodology for calculating LCOE, which allows for a fair and precise comparison of renewable energy generation options in rural areas. It contributes to informed and transparent decision-making in the fields of energy policy and public investment for expanding electricity service coverage. The proposed methodology is based on the financial cash flow matrix to address variability sources in the calculation, considering the local context of the generation project.

The Financial Model for Water and Sanitation Services in Portugal: Lessons from Decades of Subsidies and Questionable Public Policies

Despite the billions of euros used as subsidies over recent decades, Portugal’s water sector continues to struggle, being characterized by significant inefficiencies and differences between high- and low-performing water and sanitation services (WSSs). Current subsidy policies lack transparency and are not linked to performance results, undermining efforts to promote efficiency and sustainability in both environmental and financial dimensions. To address these issues, this article highlights relevant aspects to be taken into account in the redefinition of funding allocation in the Portuguese WSS sector. By implementing performance-based criteria for subsidy allocation and prioritization, regardless of the identity of beneficiaries or providers, we aim to instigate accountability and efficiency in this process. The analysis draws on empirical data to highlight the shortcomings of existing practices and demonstrates the potential benefits of adopting the “user-pays” principle. This principle is able to improve the definition of tariffs aiming for full cost recovery, while still providing for disadvantaged and vulnerable customers through social tariffs or assistance programs. Key findings indicate that coordinated efforts among government agencies, regulators, public and private utilities, and municipalities are essential to develop and promote effective financing strategies. This stakeholder’s cooperation is essential for managing the urban water cycle sustainably and addressing the sector’s long-term challenges. This research implies that a strategic shift in subsidy allocation is required, to develop accountability, efficiency, and equity in the WSS sector. The allocation of financial resources must be better justified to enhance overall performance in the sector.

Personal responsibility for health in Bulgarian public health law and social legislation

BackgroundIn the last decades all health systems have experienced a lack of resources. Against this background, the idea of ​​applying personal responsibility of the patient as a criterion for allocation of resources (PRCAR) is gaining increasing attention. Bulgarian healthcare reform has been marked by the implementation of many new strategies, that grounded our scientific interest towards investigating PRCAR in Bulgarian public health law and social legislation.MethodsThrough a search of national legal databases 7 documents were selected and subjected to content analysis.ResultsProspective responsibility was found in two and retrospective responsibility - in three documents, two of which imposed explicit penalties on the patient. Two documents did not distinguish between the types of patient responsibility. PRCAR was found to be controversial through the prism of the social justice principle. The discussion was conducted through the perspectives of evidence translation of research to law, particularities of social cohesion in Bulgaria, and the interpretation of principles of public health ethics.ConclusionAlthough PRCAR was traceable in Bulgarian legislation, no supporting arguments for its introduction were deduced. The applicability of PRCAR should be further studied and wider public debate should be initiated.

On the Different Fair Allocations of Economic Benefits for Energy Communities

Energy Communities (ECs) are aggregations of users that cooperate to achieve economic benefits by sharing energy instead of operating individually in the so-called “disagreement” case. As there is no unique notion of fairness for the cost/profit allocation of ECs, this paper aims to identify an allocation method that allows for an appropriate weighting of both the interests of an EC as a whole and those of all its members. The novelty is in comparing different optimization approaches and cooperative allocation criteria, satisfying different notions of fairness, to assess which one may be best suited for an EC. Thus, a cooperative model is used to optimize the operation of an EC that includes two consumers and two solar PV prosumers. The model is solved by the “Social Welfare” approach to maximizing the total “incremental” economic benefit (i.e., cost saving and/or profit increase) and by the “Nash Bargaining” approach to simultaneously maximize the total and individual incremental economic benefits, with respect to the “disagreement” case. Since the “Social Welfare” approach could lead to an unbalanced benefit distribution, the Shapley value and Nucleolus criteria are applied to re-distribute the total incremental economic benefit, leading to higher annual cost savings for consumers with lower electricity demand. Compared to “Social Welfare” without re-distribution, the Nash Bargaining distributes 39–49% and 9–17% higher annual cost savings to consumers with lower demand and to prosumers promoting the energy sharing within the EC, respectively. However, total annual cost savings drop by a maximum of 5.5%, which is the “Price of Fairness”.

A study on the introduction of mixed payment compensation system through top-down cost information analysis in Korea

This study aims to identify the problems of the Korean health insurance fee system and to suggest a reasonable insurance fee construction alternative using the cost analysis data of hospitals. To this end, the characteristics of the medical fee payment system and hospital cost analysis were examined, and the cost data of one national public general hospital were used for the analysis. The cost allocation criteria were divided into labor costs, material costs, pharmaceutical costs, equipment costs, and overhead costs, and a top-down cost analysis was conducted. The analysis results showed that the cost was greater than the income in the case of outpatient and inpatient treatment performance, and the analysis results on the amount of physician workload showed that the relative value of physician workload calculated based on the cost was analyzed to require an increase of 1.52 times for hospitalization fees and 1.72 times for examination fees. The main factor affecting the cost compensation rate was that when the proportion of examination fees was high, the cost compensation level increased, while on the other hand, the cost compensation rate decreased as the proportion of physician labor costs increased or the length of stay increased. In order to resolve the ongoing complaints of medical service providers under the current fee-for-service system and secure the appropriateness of health insurance compensation rates, compensation for physician fees should be induced to realize the level of cost compensation through cost-based, per-service fee calculations, and the rationality of the payment compensation system can be secured by securing autonomy of providers through bundled fees for hospital costs and changing the payment method.

Factors Associated with Waitlist Time on Liver Transplantation

Objectives: Liver transplantation (LT) is the main therapy for patients with cirrhosis or fulminant liver failure. However, there is a disproportion between the demand and availability of organs, such that the waitlist mortality ranged from 20 to 38% when the only allocation criterion was the time of inclusion on the waitlist. Brazil then adopted the Model for End-stage Liver Disease (MELD) score, aiming to prioritize patients with a higher risk of death for LT. !erefore, this study aimed to determine factors associated with waitlist time for LT. Methods: Retrospective cohort study of adult patients listed for LT from October 2012 to December 2019 in a single state in Brazil. Results: !e study analyzes 1,262 patients (869 males, 68.91%; median age, 53.33 ± 11.48 years; median waitlist time, 103.88 ± 162.05 days; median MELD Sodium [MELD-Na] score of 22.41 ± 6.09). Alcoholic liver cirrhosis (n = 369; 29.24%) and chronic viral hepatitis (n = 295; 23.38%) were the most prevalent reasons for LT. Blood groups O (n = 534; 42.31%) and A (n = 474; 37.56%) prevailed among the recipients. !e state capital and its metropolitan region accounted for 91.20% (n = 1,151) of all liver transplants performed. Most donors were deceased (n = 1,258; 99.68%). Patients with MELD-Na scores > 21 (p < 0.001), non-O blood group (p = 0.002), age < 53 years (p = 0.003), and those listed ≥ 2017 spent ≤ 30 days on the waitlist (p < 0.001). Conclusion: A waitlist period of ≤ 30 days was associated with higher MELD-Na scores, younger ages, non-O blood groups, and LT listings before 2017.

Acute Kidney Injury after Liver Transplantation

Abstract Liver transplantation is the only curative treatment for terminal liver failure. Advances in immunosuppressive therapy and improvements in surgical techniques have improved patient survival in the post-transplant period. At the same time, however, the incidence of late complications is increasing, which has been contributed to by the broadening of the indication criteria in liver allocation. The most common complications include chronic kidney disease, the aetiology of which is multifactorial with a predominance of calcineurin inhibitor toxicity in the post-transplant period. The prevalence ranges from 30% to 90% depending on the definition used and the methodology used to measure renal function. Early detection of risk factors and early intervention lead to a significant improvement in the quality of life of recipients in the post-transplant period.

Determination of Accommodation Tax Spending Areas Using the SWARA Method

The allocation of revenue generated from the accommodation tax, which has recently been introduced in Türkiye, has not been specified within the framework of the law. In this context, the aim of the research is to determine the spending areas and establish priority ranking for the tax collected from tourists. In this regard, data was collected using a survey form consisting of 20 criteria and analyzed using the SWARA method. Upon examining the research findings, the highest average criteria for allocation are financing activities, improving infrastructure and superstructure services, preserving and restoring natural and cultural heritage sites, investing in destination marketing efforts, maintaining museums, and creating recreation activity areas. The lowest average criteria, on the other hand, include supporting projects for refugee integration, providing holiday support to disadvantaged groups, and offering campaigns for public transportation services. As a result of the research, participants indicated that the tax revenue should be allocated to creating permanent structures, restoration and maintenance efforts, and areas related to destination marketing rather than campaigns, projects, or aids that would directly benefit tourists, local residents, or refugees.

Contemporary Bridge to Heart Transplantation With Venoarterial Extracorporeal Membrane Oxygenation.

Objective: In October 2018, the United Network for Organ Sharing changed their heart allocation criteria to prioritize patients on temporary mechanical circulatory support. This study assesses outcomes of patients bridged to orthotopic heart transplantation (OHT) with venoarterial extracorporeal membrane oxygenation (VA ECMO) since this change. Methods: We conducted a retrospective single-center study of adults (≥18 years) supported with VA ECMO at the time of OHT (October 1, 2018, to December 31, 2021). The primary outcome was midterm survival. Results: During the study period, 117 patients underwent OHT including 52 adults ≥18 years (44%) and 65 children <18 years (56%). Among adults, 8 (15%) were supported with VA ECMO at the time of OHT and are included in this study; 75% were male (n = 6), and the median age was 52.5 (interquartile range [IQR] = 23.5 to 57.25) years. Most patients were peripherally cannulated (75%, n = 6) and supported with an intra-aortic balloon pump during the pretransplant period (87.5%, n = 7). The median ECMO duration was 7 (IQR = 4.5 to 25.25) days. Three patients experienced complications on ECMO (37.5%), including thromboembolic bowel infarction (12.5%, n = 1) and bleeding requiring reintervention (25%, n = 2). All patients survived to discharge without posttransplantation complications and were alive at the latest follow-up. The median follow-up time was 24.8 (IQR = 19.5 to 28.2) months. Conclusions: Patients can be successfully bridged with VA ECMO directly to OHT with excellent midterm results. Key contributors to our outcomes include early extubation, use of bivalirudin over heparin, ambulation, and rehabilitation while on ECMO.

Minimizing Misconceptions: Designing an Electrical and Magnetic Syllabus for Prospective Elementary School Teachers Using Predict Observe Explain-Conceptual Change Text (POE-CCT)

This study aims to 1) Obtain empirical data on the needs analysis for developing electrical and magnetic learning devices using the Predict-Observe-Explain (POE) approach assisted by Conceptual Change Text (CCT), and 2) Gather comprehensive information on designing a syllabus for electricity and magnetism using POE assisted by CCT. This qualitative research focuses on the define and design stages of the 4D model and involves 30 second-semester students from the Elementary School Teacher Education Study Program, including 6 men and 24 women, enrolled in the Basic Science Concepts course. Data collection methods included interviews to develop and validate a product based on needs analysis, such as graduate learning outcomes related to the course, relevant study materials, learning methods, time allocation, learning resources, references, learning media, and assessment criteria. The data was analyzed using content analysis techniques. The findings of this study confirm that 1) A learning tool using the POE-CCT approach is necessary to reduce misconceptions among prospective elementary school teachers, particularly in understanding the domains of electricity and magnetism, which are conceptually complex. The designed syllabus aims to address these misconceptions by incorporating POE learning tools assisted by CCT. This includes stages where students predict outcomes and reasons, observe and record their findings, and explain their observations followed by class discussions. 2) The syllabus development stage, based on needs analysis, results in POE learning tools with CCT assistance that promote independent prediction, observation, and explanation. This structured approach enhances active engagement, deeper understanding, and conceptual refinement through collaborative discourse, promising improved comprehension and retention of complex scientific concepts in the classroom.

How to control China's total amount of carbon emissions? An analysis of provincial allowance demands

Establishing a total amount control system for carbon emissions is crucial for China to achieve its carbon peak and neutrality targets. Given the heterogeneity among provinces, it is essential to consider provincial demands for carbon emission allowances (CEA) when allocating China's total amount target of carbon emissions. By identifying provincial preferences for different allocation criteria (equality, responsibility, capability, and efficiency), this study proposed a CEA allocation scheme that contributes to achieving China's 2030 carbon emission target with the least compromise among provinces. The results show that emission reduction efforts vary widely across provinces under any single-criterion scheme. Preferences for allocation criteria diverge among provinces, with a notable preference towards responsibility and equality. However, adhering to provincial expectations for CEA could jeopardize the attainment of national emission reduction target. The least-compromise allocation scheme integrates various criteria while weighting them differently: equality (0.42), responsibility (0.28), efficiency (0.16), and capability (0.14). Considering the varying pressure for emission reduction among provinces, it is vital to formulate differentiated policies and measures.

Ethical prioritization of critical care resources during COVID-19: perspectives from Italy and the United States.

This article examines some of the ethical challenges of prioritizing intensive care resources during the Covid-19 pandemic by comparing the Italian and United States contexts. After presenting an overview to the clinical, ethical, and public debates in Italy, the article will discuss the development of triage allocation protocols in United States hospitals. Resource allocation criteria underwent increased scrutiny and critique in both countries, which resulted in modified professional and expert guidance regarding healthcare ethics during times of emergency and resource scarcity.

Listening to Stakeholders' Voices on Funding Social Inclusion in Sport for People with Disabilities-Proposal for Criteria.

The value of sport is extensively documented; however, there are still groups who do not have the opportunity to enjoy the benefits of sport due to lack of investment, particularly important for people with disabilities. A gap persists in understanding the effectiveness of inclusive sport programs in addressing equity-related targets, particularly on the effective methods of financing inclusion in sport for individuals with disabilities. Therefore, providing a platform for stakeholders to express their perspectives becomes crucial. Through focus groups and the World Café approach, the aim of this study was to gather insights from athletes, parents, professionals, and sport club managers regarding the funding of inclusive sport for people with disabilities. A total of 72 participants took part in nine focus groups in Portugal, Slovenia, and Hungary: 27 athletes with disabilities, 22 coaches, other technicians and parents, and 23 club managers/directors. Findings were divided into five topics: (1) perspectives on current funding satisfaction; (2) perspectives on sources and criteria for funding; (3) perspectives on ideal funding; (4) perspectives on ideas to reach decision-makers; and (5) proposals on ideal criteria for funding. Based on these findings, six measurable criteria for fair funding allocation were suggested that could develop a properly weighted system of criteria for decision-makers to assess the allocation of funding among inclusive sport organizations with the potential to catalyze broader policy and societal changes. Additionally, there is a pressing need to develop a funding model for inclusive sport for individuals with disabilities.

Alleinerziehende in der Betreuungsplatzvergabe: Status quo und Handlungsempfehlungen

Abstract Single parents and their children benefit particularly from early childhood education and childcare programmes. Nevertheless, almost a third of single parents in Germany who need childcare for their children under the age of three are unable to find it. Although around 70 % of day care providers claim to take the single-parent criterion into account when allocating slots, the prevailing allocation procedures cannot guarantee that this is implemented. This article shows how transparent allocation criteria can be designed nationwide and how their implementation can be realised through suitable, centralised, municipal allocation systems. Particularly in (western) German regions with a high unmet demand for institutional childcare, single-parent status should be considered as an independent criterion in addition to other factors such as employment and child age.

Needs assessment in long-term care: expression of national principles for priority setting in service allocation

BackgroundLong-term care services for older adults are characterised by increasing needs and scarce resources. Political strategies have led to the reorganisation of long-term care services, with an increased focus on “ageing in place” and efficient use of resources. There is currently limited research on the processes by which resource allocation decisions are made by service allocators of long-term care services for older adults. The aim of this study is to explore how three political principles for priority setting in long-term care, resource, severity and benefit, are expressed in service allocation to older adults.MethodsThis qualitative study uses data from semi-structured individual interviews, focus groups and observations of service allocators who assess needs and assign long-term care services to older adults in Norway. The data were supplemented with individual decision letters from the allocation office, granting or denying long-term care services. The data were analysed using reflexive thematic analysis.ResultsThe allocators drew on all three principles for priority setting when assessing older adults’ long-term care needs and allocating services. We found that the three principles pushed in different directions in the allocation process. We identified six themes related to service allocators’ expression of the principles: (1) lowest effective level of care as a criterion for service allocation (resource), (2) blanket allocation of low-cost care services (resource), (3) severity of medical and rehabilitation needs (severity), (4) severity of care needs (severity), (5) benefit of generous service allocation (benefit) and (6) benefit of avoiding services (benefit).ConclusionsThe expressions of the three political principles for priority setting in long-term care allocation are in accordance with broader political trends and discourses regarding “ageing in place”, active ageing, an investment ideology, and prioritising those who are “worse off”. Increasing attention to the rehabilitation potential of older adults and expectations that they will take care of themselves increase the risk of not meeting frail older adults’ care needs. Additionally, difficulties in defining the severity of older adults’ complex needs lead to debates regarding “worse off” versus potentiality in future long-term care services allocation.Trial registrationNot applicable.

ECMO as a bridge to heart transplantation: Insights into stratification by heart failure etiology

PurposeRevisions to the heart allocation criteria in 2018 motivated an increased use of extracorporeal membrane oxygenation (ECMO) as a bridge to transplantation. Studies have demonstrated inferior post-transplant outcomes in patients bridged with ECMO but do not account for underlying diagnosis. Our objective was to elucidate the differential impact of ECMO on outcomes by heart failure (HF) etiology. MethodsThe United Network of Organ Sharing (UNOS) database was queried for adults who underwent isolated heart transplantation after October 2018. Patients were stratified by ECMO utilization at time of transplantation, and then by HF etiology. After baseline statistical comparisons, survival analysis relied on Kaplan-Meier estimates and Cox proportional models. Results13,203 patients were included, of whom 761 (5.8%) were supported with ECMO. ECMO patients were younger (48 vs. 54 years, p<0.001), less likely to have diabetes (24% vs 30%, p<0.001), smoke cigarettes (31% vs 41%, p<0.001) or have prior cardiac surgery (29% vs. 36%, p<0.001), more likely to require dialysis (20% vs. 5%, p<0.001), and spent fewer days on the waitlist (59 vs. 190, p<0.001). After adjustment, ECMO was associated with increased mortality (HR 1.85, p<0.001) in the full cohort. After incorporating HF etiology, this increased mortality risk persisted in all subgroups except restrictive cardiomyopathy and congenital heart disease (CHD). ConclusionsOur findings illustrate that HF etiology is associated with differing outcomes when bridging with ECMO. ECMO patients with restrictive cardiomyopathy or CHD did not have increased mortality risk. With ECMO utilization increasing, these data are hypothesis-generating and serve as a basis for further studies.

Collaborative target assignment problem for large-scale UAV swarm based on two-stage greedy auction algorithm

This paper introduces a collaborative allocation model designed for multiple UAVs and diverse targets in maritime combat situations. The model incorporates factors such as distance, angle, interception rate, and recognition rate to comprehensively represent the UAVs' overall damage advantage against targets. Given the complexity of real-world environments and real-time demands, large-scale UAV swarm missions necessitate swift and effective responses. To address this, the paper proposes a Two-Stage Greedy Auction Algorithm, enabling the rapid and efficient completion of cooperative strike tasks within large-scale UAV swarms while preventing deadlock occurrences. In the initial allocation stage, the entropy weight method is utilized to assess task advantages, ensuring a rational allocation criterion for various metrics during the strike process. Subsequently, to enhance the overall effective strike rate within all constraints, a reassignment algorithm is designed based on effective strike benefit indices and the initial assignment result. Simulation results demonstrate the algorithm's quick and stable running time in small-scale and large-scale scenarios.

The hydrometallurgical recovery of critical and valuable elements from WEEE shredding dust: Process effectiveness in a life cycle perspective

Waste electrical and electronic equipment (WEEE) recycling stands as a crucial opportunity to get critical resources while managing a waste stream in accordance with the circular economy principles. Recently, a two-step hydrometallurgical process has been successfully investigated to treat the dust originating from the mechanical processing of WEEE. The best operating conditions selected in this study were used to further investigate the recovery of precious metals and critical elements, achieving extraction yields of approximately 77.7 % and 53.1 %, respectively; base metals (i.e. aluminum, zinc, copper, ..) were also leached from dust up to 96 %. A life cycle approach was also applied to preliminary assess and compare the potential environmental impact of the proposed process with respect to the manufacturing process of the virgin material. The analysis focused on standard environmental indicators (i.e. global warming potential, acidification, …), human toxicity and eco-toxicty and a set of five different characterisation models for abiotic depletion of resources. Four scenarios, differing for allocation criteria (mass/economic) and the possible recovery of metals along with REEs, were compared. Among the recovered products, the greates potential benefits were found in the case of rare earth elements, in the scenario considering the complete recovery of base and precious metals and performing an economic allocation. Impacts on abiotic depletion and toxicity account for the highest benefits from maerial recovery. Nevertheless, the recovery of sulphuric acid would allow a further reduction also in other impacts, strengthening the potential competitiveness of REE recovery against the manufacturing of virgin materials.

Impact of age over 70 years in the new allocation system on the outcomes of heart transplantation in the US.

United Network for Organ Sharing (UNOS) allocation criteria changed in 2018 to accommodate the increased prevalence of patients on a ventricular assist device as a bridge to heart transplant and prioritize sicker people in anticipation of a heart graft. We aimed to assess the impact of patient age in the new allocation policy on mortality following heart transplantation. Secondary outcomes included the effect of age ≥70 on post-transplant events, including stroke, dialysis, pacemaker, and rejection requiring treatment. The UNOS Registry was queried to identify patients who underwent heart transplants alone in the US between 2000 and 2021. Patients were divided into groups according to their age (over 70 and under 70 years old). Patients aged over 70 were more likely to require dialysis during follow-up, but less likely to experience rejection requiring treatment, compared with patients aged <70. Age ≥70 in the new allocation system was a significant predictor of 1-year mortality (adjusted HR: 1.41; 95% CI: 1.05-1.91; p=.024), but its effect on 5-year mortality was not significant after adjusting for potential confounders (adjusted HR: 1.27; 95% CI:.97-1.66; p=.077). Undergoing transplantation under the new allocation policy vs the old allocation policy was not a significant predictor of mortality in patients over 70 years old. Age ≥70 is a significant predictor of 1-year mortality following heart transplantation, but not at 5 and 10 years; however, the new allocation does not seem to have changed the outcomes for this group of patients.

Digital Content Creation: An Analysis of the Impact of Recommendation Systems

The success of digital content platforms, such as YouTube, relies on both the creativity of independent content creators and the efficiency of content distribution. By sharing advertising revenue with content creators, these platforms can motivate creators to exert greater effort. Most platforms use recommendation systems to deliver personalized content recommendations to each consumer. As creators’ revenues are contingent on their demand, the demand allocation criteria inherent in the recommendation system can influence their content creation behavior. In this paper, we investigate the influence of a platform’s recommendation system on revenue-sharing plans, content creation, profits, and welfare. Our results show that a platform could benefit by biasing recommendations, that is, recommending content that is not an ideal match to a consumer’s preference, to incentivize creators to produce better-quality content. We refer to this as a biased recommendation strategy. Interestingly, we find that such a biased recommendation strategy may lead to a win-win in which the platform, consumers, and content creators can benefit. Our study also shows that consumers may be worse off when they are more knowledgeable and less dependent on the recommendation system. In addition, the platform, consumers, and creators can benefit when the platform has more accurate information on consumer preferences. This paper was accepted by Raphael Thomadsen, marketing.
